Description:
CROSS REFERENCE 
     The present application for patent claims the benefit of U.S. Provisional Patent Application No. 63/136,297 by KHOSHNEVISAN et al., entitled “TECHNIQUES FOR SIGNALING USER EQUIPMENT CAPABILITY FOR PDCCH REPETITION,” filed Jan. 12, 2021, assigned to the assignee hereof, and expressly incorporated by reference herein. 
    
    
     TECHNICAL FIELD 
     The following relates to wireless communications, including techniques for signaling user equipment capability for physical downlink control channel (PDCCH) repetition. 
     BACKGROUND 
     Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE). 
     Some wireless systems may support the repetition of various signals, such as control information or data. For example, multiple repetitions of a physical downlink control channel (PDCCH) transmission may be transmitted within a single slot (e.g., intra-slot PDCCH repetition), across multiple slots (e.g., inter-slot PDCCH repetition), or both. By way of another example, in the context of single frequency networks (SFNs), a base station may transmit multiple linked (e.g., related) PDCCH transmissions, where each PDCCH transmission is associated with two transmission configuration indicators (TCIs). 
     SUMMARY 
     The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for signaling user equipment capability for physical downlink control channel (PDCCH) repetition. Generally, the described techniques provide for signaling and other techniques which enable a UE to inform the network that the UE is able to support receipt of single-frequency network (SFN) PDCCH transmissions, inter-slot PDCCH repetitions, or intra-slot PDCCH repetitions, or any combination thereof. In some aspects, a UE may indicate a capability to receive/decode multiple related downlink control channel transmissions using a UE capability report which indicates that the UE is able to receive multiple PDCCH repetitions, including SFN PDCCH transmissions, inter-slot PDCCH repetitions, and/or intra-slot PDCCH repetitions.

     DETAILED DESCRIPTION 
     Some wireless systems may support the repetition of various signals, such as control information or data. For example, multiple repetitions of a physical downlink control channel (PDCCH) transmission may be transmitted within a single slot (e.g., intra-slot PDCCH repetition), across multiple slots (e.g., inter-slot PDCCH repetition), or both. By way of another example, in the context of single frequency networks (SFN), a base station may transmit multiple linked (e.g., related) PDCCH transmissions, where each PDCCH transmission is associated with two transmission configuration indicators (TCIs). In these cases, a user equipment (UE) may receive and combine the multiple related PDCCH transmissions (e.g., PDCCH repetitions), which may serve to enhance reliability in the system and also provide transmission diversity for protection against interference. 
     However, not all UEs and other wireless devices may have the capability to receive and/or decode inter-slot PDCCH repetitions, intra-slot PDCCH repetitions, SFN PDCCH transmissions, or any combination thereof. Moreover, some UEs may be able to receive and/or decode related PDCCH transmissions according to one configuration, but another (e.g., a UE may support intra-slot PDCCH repletion, but not inter-slot PDCCH repetition). Accordingly, in some wireless communications systems, a network may not be aware of which UEs are capable of supporting SFN PDCCH transmissions, inter-slot PDCCH repetitions, or intra-slot PDCCH repetitions. As such, the network may refrain from communicating with the UEs via SFN PDCCH transmissions, inter-slot PDCCH repetitions, or intra-slot PDCCH repetitions, which may reduce a reliability of wireless communications within the wireless communications system and reduce transmission diversity. 
     Accordingly, techniques described herein may provide for signaling and other techniques which enable a UE to inform the network that the UE is able to support receipt of SFN PDCCH transmissions, inter-slot PDCCH repetitions, or intra-slot PDCCH repetitions, or any combination thereof. In some aspects, a UE may indicate a capability to receive/decode multiple related downlink control channel transmissions using a UE capability report which indicates that the UE is able to receive multiple PDCCH repetitions, including SFN PDCCH transmissions, inter-slot PDCCH repetitions, and/or intra-slot PDCCH repetitions. Based on the indicated UE capability, the UE may receive a configuration for receiving multiple related PDCCH transmissions, and may monitor a PDCCH in accordance with the configuration. 
     In some implementations, and in addition to indicating the types of multiple related PDCCH transmissions that are supported, the UE capability transmitted to the network may indicate additional parameters associated with each of the supported configurations. For example, the UE capability may indicate a maximum quantity of slots between related PDCCH transmissions, whether search space sets for related PDCCH transmissions may be overlapping in time/frequency, a maximum number of monitoring occasions within a single slot it may support, supported downlink control information (DCI) formats for related PDCCH transmissions, whether control resource sets (CORESETS) for related PDCCH transmissions may be the same or different, and the like. 
     Aspects of the disclosure are initially described in the context of wireless communications systems. Additional aspects of the disclosure are described in the context of an example process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for signaling user equipment capability for PDCCH repetition. 
       FIG. 1  illustrates an example of a wireless communications system  100  that supports techniques for signaling user equipment capability for PDCCH repetition in accordance with aspects of the present disclosure. The wireless communications system  100  may include one or more base stations  105 , one or more UEs  115 , and a core network  130 . In some examples, the wireless communications system  100  may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communications system  100  may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof. 
     The base stations  105  may be dispersed throughout a geographic area to form the wireless communications system  100  and may be devices in different forms or having different capabilities. The base stations  105  and the UEs  115  may wirelessly communicate via one or more communication links  125 . Each base station  105  may provide a coverage area  110  over which the UEs  115  and the base station  105  may establish one or more communication links  125 . The coverage area  110  may be an example of a geographic area over which a base station  105  and a UE  115  may support the communication of signals according to one or more radio access technologies. 
     The UEs  115  may be dispersed throughout a coverage area  110  of the wireless communications system  100 , and each UE  115  may be stationary, or mobile, or both at different times. The UEs  115  may be devices in different forms or having different capabilities. Some example UEs  115  are illustrated in  FIG. 1 . The UEs  115  described herein may be able to communicate with various types of devices, such as other UEs  115 , the base stations  105 , or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown in  FIG. 1 . 
     The base stations  105  may communicate with the core network  130 , or with one another, or both. For example, the base stations  105  may interface with the core network  130  through one or more backhaul links  120  (e.g., via an S1, N2, N3, or other interface). The base stations  105  may communicate with one another over the backhaul links  120  (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations  105 ), or indirectly (e.g., via core network  130 ), or both. In some examples, the backhaul links  120  may be or include one or more wireless links. 
     One or more of the base stations  105  described herein may include or may be referred to by a person having ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB), a Home NodeB, a Home eNodeB, or other suitable terminology. 
     A UE  115  may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE  115  may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA), a multimedia/entertainment device (e.g., a radio, a MP3 player, or a video device), a camera, a gaming device, a navigation/positioning device (e.g., GNSS (global navigation satellite system) devices based on, for example, GPS (global positioning system), Beidou, GLONASS, or Galileo, or a terrestrial-based device), a tablet computer, a laptop computer, a personal computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), a drone, a robot/robotic device, a vehicle, a vehicular device, a meter (e.g., parking meter, electric meter, gas meter, water meter), a monitor, a gas pump, an appliance (e.g., kitchen appliance, washing machine, dryer), a location tag, a medical/healthcare device, an implant, a sensor/actuator, a display, or any other suitable device configured to communicate via a wireless or wired medium. In some examples, a UE  115  may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples. 
     Some UEs  115 , such as MTC or IoT devices, may be low cost or low complexity devices, and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a base station  105  without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay that information to a central server or application program that can make use of the information or present the information to humans interacting with the program or application. Some UEs  115  may be designed to collect information or enable automated behavior of machines. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging. In an aspect, techniques disclosed herein may be applicable to MTC or IoT UEs. MTC or IoT UEs may include MTC/enhanced MTC (eMTC, also referred to as CAT-M, Cat M1) UEs, NB-IoT (also referred to as CAT NB1) UEs, as well as other types of UEs. eMTC and NB-IoT may refer to future technologies that may evolve from or may be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (enhanced further eMTC), and mMTC (massive MTC), and NB-IoT may include eNB-IoT (enhanced NB-IoT), and FeNB-IoT (further enhanced NB-IoT). 
     Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). A wireless network, for example a wireless local area network (WLAN), such as a Wi-Fi (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network may include an access point (AP) that may communicate with one or more wireless or mobile devices. The AP may be coupled to a network, such as the Internet, and may enable a mobile device to communicate via the network (or communicate with other devices coupled to the access point). A wireless device may communicate with a network device bi-directionally. For example, in a WLAN, a device may communicate with an associated AP via downlink (e.g., the communication link from the AP to the device) and uplink (e.g., the communication link from the device to the AP). A wireless personal area network (PAN), which may include a Bluetooth connection, may provide for short range wireless connections between two or more paired wireless devices. For example, wireless devices such as cellular phones may utilize wireless PAN communications to exchange information such as audio signals with wireless headsets. Components within a wireless communication system may be coupled (for example, operatively, communicatively, functionally, electronically, and/or electrically) to each other. 
     The UEs  115  described herein may be able to communicate with various types of devices, such as other UEs  115  that may sometimes act as relays as well as the base stations  105  and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in  FIG. 1 . 
     The UEs  115  and the base stations  105  may wirelessly communicate with one another via one or more communication links  125  over one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication links  125 . For example, a carrier used for a communication link  125  may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP)) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system  100  may support communication with a UE  115  using carrier aggregation or multi-carrier operation. A UE  115  may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. 
     In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and may be positioned according to a channel raster for discovery by the UEs  115 . A carrier may be operated in a standalone mode where initial acquisition and connection may be conducted by the UEs  115  via the carrier, or the carrier may be operated in a non-standalone mode where a connection is anchored using a different carrier (e.g., of the same or a different radio access technology). 
     The communication links  125  shown in the wireless communications system  100  may include uplink transmissions from a UE  115  to a base station  105 , or downlink transmissions from a base station  105  to a UE  115 . Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode). 
     A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system  100 . For example, the carrier bandwidth may be one of a number of determined bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communications system  100  (e.g., the base stations  105 , the UEs  115 , or both) may have hardware configurations that support communications over a particular carrier bandwidth or may be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communications system  100  may include base stations  105  or UEs  115  that support simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE  115  may be configured for operating over portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth. 
     Signal waveforms transmitted over a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements that a UE  115  receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE  115 . A wireless communications resource may refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with a UE  115 . 
     The time intervals for the base stations  105  or the UEs  115  may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T s =1/(Δf max ·N f ) seconds, where Δf max  may represent the maximum supported subcarrier spacing, and N f  may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023). 
     Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on subcarrier spacing. Each slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period). In some wireless communications systems  100 , a slot may further be divided into multiple mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f ) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation. 
     A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system  100  and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system  100  may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)). 
     Physical channels may be multiplexed on a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed on a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs  115 . For example, one or more of the UEs  115  may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to a number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs  115  and UE-specific search space sets for sending control information to a specific UE  115 . 
     In some examples, a base station  105  may be movable and therefore provide communication coverage for a moving geographic coverage area  110 . In some examples, different geographic coverage areas  110  associated with different technologies may overlap, but the different geographic coverage areas  110  may be supported by the same base station  105 . In other examples, the overlapping geographic coverage areas  110  associated with different technologies may be supported by different base stations  105 . The wireless communications system  100  may include, for example, a heterogeneous network in which different types of the base stations  105  provide coverage for various geographic coverage areas  110  using the same or different radio access technologies. 
     The wireless communications system  100  may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system  100  may be configured to support ultra-reliable low-latency communications (URLLC) or mission critical communications. The UEs  115  may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission critical functions). Ultra-reliable communications may include private communication or group communication and may be supported by one or more mission critical services such as mission critical push-to-talk (MCPTT), mission critical video (MCVideo), or mission critical data (MCData). Support for mission critical functions may include prioritization of services, and mission critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission critical, and ultra-reliable low-latency may be used interchangeably herein. 
     In some examples, a UE  115  may also be able to communicate directly with other UEs  115  over a device-to-device (D2D) communication link  135  (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs  115  utilizing D2D communications may be within the geographic coverage area  110  of a base station  105 . Other UEs  115  in such a group may be outside the geographic coverage area  110  of a base station  105  or be otherwise unable to receive transmissions from a base station  105 . In some examples, groups of the UEs  115  communicating via D2D communications may utilize a one-to-many (1:M) system in which each UE  115  transmits to every other UE  115  in the group. In some examples, a base station  105  facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs  115  without the involvement of a base station  105 . 
     The core network  130  may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network  130  may be an evolved packet core (EPC) or 5G core (5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs  115  served by the base stations  105  associated with the core network  130 . User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services  150  for one or more network operators. The IP services  150  may include access to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS), or a Packet-Switched Streaming Service. 
     Some of the network devices, such as a base station  105 , may include subcomponents such as an access network entity  140 , which may be an example of an access node controller (ANC). Each access network entity  140  may communicate with the UEs  115  through one or more other access network transmission entities  145 , which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs). Each access network transmission entity  145  may include one or more antenna panels. In some configurations, various functions of each access network entity  140  or base station  105  may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station  105 ). 
     The wireless communications system  100  may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. The UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs  115  located indoors. The transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz. 
     The wireless communications system  100  may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communications system  100  may employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as the base stations  105  and the UEs  115  may employ carrier sensing for collision detection and avoidance. In some examples, operations in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA). Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples. 
     A base station  105  or a UE  115  may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a base station  105  or a UE  115  may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a base station  105  may be located in diverse geographic locations. A base station  105  may have an antenna array with a number of rows and columns of antenna ports that the base station  105  may use to support beamforming of communications with a UE  115 . Likewise, a UE  115  may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support radio frequency beamforming for a signal transmitted via an antenna port. 
     The base stations  105  or the UEs  115  may use MIMO communications to exploit multipath signal propagation and increase the spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices. 
     Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station  105 , a UE  115 ) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating at particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation). 
     A base station  105  or a UE  115  may use beam sweeping techniques as part of beam forming operations. For example, a base station  105  may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE  115 . Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a base station  105  multiple times in different directions. For example, the base station  105  may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device, such as a base station  105 , or by a receiving device, such as a UE  115 ) a beam direction for later transmission or reception by the base station  105 . 
     Some signals, such as data signals associated with a particular receiving device, may be transmitted by a base station  105  in a single beam direction (e.g., a direction associated with the receiving device, such as a UE  115 ). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted in one or more beam directions. For example, a UE  115  may receive one or more of the signals transmitted by the base station  105  in different directions and may report to the base station  105  an indication of the signal that the UE  115  received with a highest signal quality or an otherwise acceptable signal quality. 
     In some examples, transmissions by a device (e.g., by a base station  105  or a UE  115 ) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from a base station  105  to a UE  115 ). The UE  115  may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across a system bandwidth or one or more sub-bands. The base station  105  may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or unprecoded. The UE  115  may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted in one or more directions by a base station  105 , a UE  115  may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE  115 ) or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device). 
     A receiving device (e.g., a UE  115 ) may try multiple receive configurations (e.g., directional listening) when receiving various signals from the base station  105 , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may try multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions). 
     The wireless communications system  100  may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. A Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate over logical channels. A Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide establishment, configuration, and maintenance of an RRC connection between a UE  115  and a base station  105  or a core network  130  supporting radio bearers for user plane data. At the physical layer, transport channels may be mapped to physical channels. 
     The UEs  115  and the base stations  105  may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly over a communication link  125 . HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, where the device may provide HARQ feedback in a specific slot for data received in a previous symbol in the slot. In other cases, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval. 
     In some aspects, a UE  115  of the wireless communications system  100  may be configured with up to three CORESETS within a given BWP. A CORESET may include one or more TCI states for PDCCH repetition, and may be associated with a quantity of resource blocks (RBs) in the frequency domain, and a quantity of symbols or other TTI in the time domain (e.g., quantity of OFDM symbols). In some aspects, a CORESET configured at the UE  115  may be associated with a CCE resource element group (CCE-REG) mapping type (e.g., CCE-REG bundle mapping type), a precoding granularity, an identifier (e.g., scrambling identifier) associated with scrambling for PDCCH demodulation reference signals (DMRS), coded bits of downlink control information (DCI) content, or any combination thereof. 
     In some aspects, a UE  115  may be configured with up to ten search space sets within a given BWP. In some aspects, each search space set may be associated with a given CORESET, and may include a set of monitoring occasions. In some aspects, a search space set may include a set of control channel monitoring occasions (e.g., PDCCH monitoring occasions). Moreover, a UE  115  may be configured to determine the control channel monitoring occasions associated with a given search space set based on one or more characteristics of the search space set which may be configured (e.g., pre-configured) at the UE  115 , indicated to the UE  115  via a base station  105 , or both. A UE  115  may be configured with one or more different types of search space sets (e.g., searchSpaceType), including UE-specific search space sets, common search space sets, or both. Additionally, each search space set may be associated with one or more DCI formats which are to be monitored. 
     Parameters of a search space set (s) may include a periodicity (k s ) of monitoring occasions (e.g., k s  slots), an offset (o s ) for monitoring occasions in units of slots (e.g., o s  slots) (e.g., monitoringSlotPeriodicityAndOffset), a duration (T s ) indicative of a quantity of slots within a period in which the search space set exists (where T s &lt;k s ), or any combination thereof. A UE  115  of the wireless communications system  100  may determine a quantity of PDCCH monitoring occasions within a slot η s,f   μ  and a frame η f  if η f ·N slot   frame,μ +η s,f   μ o s  mod k s =0. In some aspects, when monitoring a control channel, a UE  115  may be configured to monitor control channel candidates (e.g., PDCCH candidates) for a search space set s for T s  consecutive slots, starting from slot μ s,f   μ , and may refrain from monitoring control channel candidates for the search space set s for the next k s −T s  consecutive slots. Quantities of control channel candidates (e.g., PDCCH candidates) may be based on an aggregation level (e.g., quantity of CCEs) of wireless communications at the UE  115 . 
     In some aspects, a UE  115  may be configured to monitor a control channel according to a control channel monitoring pattern (e.g., PDCCH monitoring pattern) within a slot (e.g., monitoringSymbolsWithinSlot). For example, a PDCCH monitoring pattern within a slot may indicate a first symbol(s) of a CORESET within a slot for PDCCH monitoring. For instance, in the context of a slot including fourteen symbols, a CORESET configured at a UE  115  may be associated with a search space set including three symbols, and a control channel monitoring pattern (e.g., monitoringSymbolsWithinSlot) associated with the search space set may be configured as “01000010001000.” In this example, the UE  115  may be configured to determine that there are three monitoring occasions within each slot that the search space set exists. Moreover, the UE  115  may be configured to determine that the three monitoring occasions begin at the second, seventh, and eleventh symbols of each respective slot that the search space exists. 
     In the context of a SFN, SFN PDCCH transmissions (e.g., PDCCH DMRS) may be associated with two TCI states. In particular, for SFN PDCCH transmissions, one CORESET may be activated at UE  115  with two active TCI states. In such cases, each control channel candidate (e.g., PDCCH candidate) of a search space set associated with the CORESET may be associated with the two active TCI states of the CORESET. 
     Similarly, for PDCCH repetitions in which each PDCCH repetition includes a PDCCH candidate, two PDCCH candidates (e.g., two PDCCH repetitions) may be linked (e.g., related) together for possible repetitions of the same control channel transmission (e.g., repetitions of DCI). In the context of PDCCH repetitions, the payload (e.g., DCI payload) of the two PDCCH candidates (e.g., two PDCCH repetitions) may be the same. For example, a first PDCCH candidate may be related, or linked, to a second PDCCH candidate. In this example, a first repetition of DCI may be transmitted in the first PDCCH candidate, and a second repetition of DCI may be transmitted in the second PDCCH candidate, where the first and second repetitions of DCI are the same. In this example, a UE  115  may receive and/or decode only the first repetition of DCI or only the second repetition of DCI. Additionally, or alternatively, the UE  115  may receive and/or decode both the first and second repetitions of DCI by performing soft combining of the first and second repetitions of DCI. In some aspects, related/linked PDCCH candidates may have the same aggregation level (e.g., same quantities of CCEs). 
     In some aspects related PDCCH candidates in different search space sets which are associated with corresponding CORESETs may be linked together (e.g., related) for PDCCH repetition. In some cases, two PDCCH candidates with a same candidate index across two related search space sets may be linked or related. In other cases, PDCCH candidates with a same start CCE index may be linked. In some aspects, sets of related/linked PDCCH candidates may be configured via control signaling (e.g., RRC signaling). For example, a UE  115  may receive an RRC message which indicates that a first PDCCH candidate in a first search space set is linked with (e.g., related to) a second PDCCH candidate in a second search space set. Moreover, UEs  115  may be configured with sets of linked/related PDCCH candidates which are within a same slot or TTI (e.g., intra-slot PDCCH repetition), sets of linked/related PDCCH candidates which are in different slots (e.g., intra-slot PDCCH repetition), or both. 
     In some aspects, the UEs  115  and the base stations  105  of the wireless communications system  100  may support signaling and other techniques which enable a UE  115  to inform the network (e.g., base stations  105 ) that the UE  115  is able to support receipt of SFN PDCCH transmissions, inter-slot PDCCH repetitions, or intra-slot PDCCH repetitions, or any combination thereof. For example, in some aspects, a UE  115  may indicate a capability to receive/decode multiple related downlink control channel transmissions using a UE capability report which indicates that the UE  115  is able to receive multiple PDCCH repetitions, including SFN PDCCH transmissions, inter-slot PDCCH repetitions, and/or intra-slot PDCCH repetitions. Based on the indicated UE capability, the UE  115  may receive, from a base station  105 , a configuration for receiving multiple related PDCCH transmissions, and may monitor a PDCCH in accordance with the configuration. For instance, in cases where the UE  115  indicates it supports inter-slot PDCCH repetitions, the UE  115  may receive a first repetition of a PDCCH transmission in a first transmission time interval (TTI) (e.g., first slot), and may receive a second repetition of the PDCCH transmission in a second TTI (e.g., second slot). By way of another example, in cases where the UE  115  indicates it supports intra-slot PDCCH repetitions, the UE  115  may receive a first repetition of a PDCCH transmission and a second repetition of the PDCCH transmission in common TTI (e.g., common slot). 
     In some implementations, the UE capability transmitted by a UE  115  to the network (e.g., to a base station  105 ) may indicate additional parameters associated with each of the supported configurations. For example, the UE capability may indicate a maximum quantity of slots between related PDCCH transmissions, whether search space sets for related PDCCH transmissions may be overlapping in time/frequency, a maximum number of monitoring occasions within a single slot it may support, supported downlink control information (DCI) formats for related PDCCH transmissions, whether control resource sets (CORESETS) for related PDCCH transmissions may be the same or different, and the like. 
     Techniques described herein may provide for improved scheduling of wireless communications. In particular, by enabling a UE  115  to inform the network (e.g., base station  105 ) its capability to support one or more configurations for PDCCH repetition (e.g., SFN PDCCH transmissions, inter-slot PDCCH repetitions, intra-slot PDCCH repetitions), techniques described herein may enable the network to communicate with the UE  115  using the respective configurations for PDCCH repetitions depending on the characteristics of the network (e.g., quantity of data traffic, noise) as well as the capabilities of the UE  115 . Thus, techniques described herein may enable more widespread use of communications using PDCCH repetitions within the wireless communications system  100 , thereby improving a reliability of wireless communications, improving transmission diversity, and further protecting wireless communications against interference. 
       FIG. 2  illustrates an example of a wireless communications system  200  that supports techniques for signaling user equipment capability for PDCCH repetition in accordance with aspects of the present disclosure. In some examples, wireless communications system  200  may implement, or be implemented by, aspects of wireless communications system  100 . For example, wireless communications system  200  may support signaling which enables a UE  115  to indicate a capability to support SFN PDCCH transmissions, inter-slot PDCCH repetitions, intra-slot PDCCH repetitions, or any combination thereof. 
     The wireless communications system  200  may include a base station  105 - a  and a UE  115 - a , which may be examples base stations  105  and UEs  115  as described with reference to  FIG. 1 . The UE  115 - a  may communicate with the base station  105 - a  using a communication link  205 , which may be an example of an NR or LTE link between the UE  115 - a  and the base station  105 - a . In some cases, the communication link  205  between the UE  115 - a  and the base station  105 - a  may include an example of an access link (e.g., Uu link) which may include a bi-directional link that enables both uplink and downlink communication. For example, the UE  115 - a  may transmit uplink signals, such as uplink control signals or uplink data signals, to the base station  105 - a  using the communication link  205  and the base station  105 - a  may transmit downlink signals, such as downlink control signals or downlink data signals, to the UE  115 - a  using the communication link  205 . 
     In some aspects, the wireless communications system  200  may support signaling which enables the UE  115 - a  to indicate, to the base station  105 - a , whether it supports receipt of SFN PDCCH transmissions, inter-slot PDCCH repetitions, or intra-slot PDCCH repetitions, or any combination thereof. For example, in some aspects, a UE  115  may indicate a capability to receive/decode multiple related downlink control channel transmissions using a UE capability report which indicates that the UE  115  is able to receive multiple PDCCH repetitions, including SFN PDCCH transmissions, inter-slot PDCCH repetitions, and/or intra-slot PDCCH repetitions. Subsequently, the base station  105 - a  may be configured to transmit, to the UE  115 - a , a configuration (e.g., configuration for SFN PDCCH transmissions, configuration for inter-slot PDCCH repetition, configuration for intra-slot PDCCH repetition), which may enable the UE  115 - a  and the base station  105 - a  to communicate according to the indicated configuration. By enabling the UE  115 - a  to indicate, to the base station  105 - a , various capabilities and/or parameters associated with a SFN PDCCH transmissions, inter-slot PDCCH repetitions, and/or intra-slot PDCCH repetitions, techniques described herein may enable improved scheduling of wireless communications at the UE  115 - a  and enable more widespread use of PDCCH repetitions. 
     For example, the UE  115 - a  may transmit a UE capability  210  indicating that the UE  115 - a  supports receipt of multiple related downlink control channel transmissions (e.g., multiple related PDCCH transmissions  220 ) which are associated with one or more CORESETs. In some aspects, the UE capability  210  may be indicated via a UE capability report. In some aspects, the UE capability  210  may indicate that it can receive and/or SFN downlink control channel transmissions (e.g., SFN PDCCH transmissions), intra-slot downlink control channel repetitions (e.g., intra-slot PDCCH repetitions), inter-slot downlink control channel repetitions (e.g., inter-slot PDCCH repetitions), or any combination thereof. 
     In this regard, the UE capability  210  may indicate that the UE  115 - a  supports a first configuration  215 - a  for receiving/decoding SFN PDCCH transmissions, a second configuration  215 - b  for receiving/decoding intra-slot PDCCH repetitions, and/or a third configuration  215 - c  for receiving/decoding inter-slot PDCCH repetitions. As shown in  FIG. 2 , in cases where the UE  115 - a  supports the first configuration  215 - a  for receiving/decoding SFN PDCCH transmissions, the UE  115 - a  may be able to receive and/or decode a first SFN PDCCH transmission  220 , and a second SFN PDCCH transmission  220  which is related to the first SFN PDCCH transmission  220 . In the context of SFN PDCCH transmissions  220 , the same coded bits may be transmitted within a common set of resource elements (e.g., within a common set of CCEs and/or CCE-REGs). In such cases, SFN PDCCH transmissions  220  may be associated with two TCI states (e.g., two beams), where the UE  115 - a  receives a combined signal of the respective SFN PDCCH transmissions  220 , which may improve channel estimation. 
     In cases where the UE  115 - a  supports the second configuration  215 - b  for receiving/decoding intra-slot PDCCH repetitions, the UE  115 - a  may be able to receive and/or decode a first PDCCH transmission  220  and a second PDCCH transmission  220  in a common slot  225  (e.g., first slot  225 - a ), where the first and second PDCCH transmissions  220  are associated with one another (e.g., linked). Similarly, in cases where the UE  115 - a  supports the third configuration  215 - c  for receiving/decoding inter-slot PDCCH repetitions, the UE  115 - a  may be able to receive and/or decode a first PDCCH transmission  220  in a first slot  225 - a , and a second PDCCH transmission  220  in a different slot (e.g., second slot  225 - b , third slot  225 - c ), where the first and second PDCCH transmissions  220  are associated with one another (e.g., linked). 
     In some cases, a network (e.g., wireless communications system  200 ) may be configured with one or more standardized configurations for receiving/decoding multiple related downlink control channel transmissions. In such cases, the UE capability  210  may indicate that the UE  115 - a  supports one or more of the configurations for receiving/decoding multiple related PDCCH transmissions  220  via one or more bit field values of a UE capability report. 
     In some aspects, the UE capability  210  may indicate that the UE supports receipt of SFN downlink control channel transmissions. In other words, the UE capability  210  may indicate that the UE  115 - a  supports the first configuration  215 - a  for SFN PDCCH transmissions  220 . As noted previously herein, in the context of SFN, each PDCCH transmission  220  (e.g., PDCCH DMRS) may be associated with two TCI states. In such cases, the UE capability  210  may include an indication of a quantity of CORESETs within a BWP which may be configured at the UE  115 - a . In particular, the UE capability  210  may include an indication of a quantity of CORESETs within a BWP which may simultaneously be associated with two active TCI states for SFN PDCCH transmissions  220 . 
     In some cases, the UE capability  210  may indicate that the UE supports receipt of intra-slot downlink control channel transmissions, inter-slot downlink control channel transmissions, or both. In other words, the UE capability  210  may indicate that the UE  115 - a  supports the second configuration  215 - b  for intra-slot PDCCH repetitions, the third configuration  215 - c  for intra-slot PDCCH repetitions, or both. In such cases, the UE capability  210  may include one or more parameters associated with intra-slot and/or inter-slot PDCCH repetitions (e.g., parameters associated with the second configuration  215 - b  and/or the third configuration  215 - c ) including, but not limited to, quantities (e.g., maximum quantity) of downlink control channel monitoring occasions (e.g., PDCCH monitoring occasions) within one or more slots  225  which may be monitored by the UE  115 - a , indications that the UE  115 - a  does or does not support monitoring of UE-specific search space sets and/or common search space sets, a format (e.g., DCI formats including DCI 1_0, DCI 2_0, DCI 3_0, etc.) for downlink control information associated with intra-slot and/or intra-slot downlink control channel repetitions, or any combination thereof. 
     For example, the UE capability  210  may indicate a maximum number of PDCCH monitoring occasions within a slot  225  which can be configured for a search space set that is linked with another search space set for inter-slot and/or intra-slot PDCCH repetitions. The indication of a maximum number of PDCCH monitoring occasions which may be monitored by the UE  115 - a  may determine allowable values of RRC parameters (e.g., monitoringSymbolsWithinSlot) which the base station  105 - a  may configure for the related/linked search space sets. By way of another example, the UE capability  210  may indicate that the UE  115 - a  may receive and/or decode UE-specific search space sets and/or common search space sets for inter-slot PDCCH repetition, intra-slot PDCCH repetition, or both. By way of another example, the UE capability  210  may indicate which DCI formats the UE  115 - a  may receive/decode for inter-slot and/or intra-slot PDCCH repetitions. In some aspects, the indication of the DCI format may determine allowable values for of RRC parameters (e.g., searchSpaceType) which the base station  105 - a  may configure for the related/linked search space sets. 
     The UE capability  210  may indicate one or more parameters associated with sets of CORESETs which are linked for inter-slot and/or intra-slot PDCCH repetition. For example, the UE capability  210  may indicate that the UE  115 - a  supports receipt of a first PDCCH transmission  220  associated with a first CORESET, and a second PDCCH transmission  220  associated with a second CORESET, where the first and second PDCCH transmissions  220  are related or linked. In this example, the UE capability  210  may indicate a first set of parameters associate with the first CORESET, and a second set of parameters associated with the second CORESET. In some cases, the first and second sets of parameters may be the same or different. The parameters associated with the respective CORESETs may include, but are not limited to, CORESET durations, CCE-REG mapping types, precoding granularity, CORESET pool indexes, or any combination thereof. 
     For instance, the UE capability  210  may indicate a quantity of symbols of the respective CORESETs (e.g., CORESET duration). The UE capability  210  may indicate if the CORESET durations of the first CORESET and the second CORESET for inter-slot and/or intra-slot PDCCH repetition should be the same, if they may be different, or if the UE  115 - a  supports both. By way of another example, the UE capability  210  may indicate whether CCE-REG mapping types (e.g., CCE-REG bundling mapping type) and/or precoding granularities of the first CORESET and the second CORESET that are associated with the linked search space sets for inter-slot and/or intra-slot PDCCH repetition may be the same, and/or if they may be different. 
     Similarly, the UE capability  210  may indicate whether the first CORESET and the second CORESET that are associated with the linked search space sets for inter-slot and/or intra-slot PDCCH repetition may be configured with CORESET pool index values (e.g., CORESETPoolIndex values). In some aspects, CORESET pool indexes may be representative of TRP IDs for multi-DCI based multi-TRP UEs  115 , such that CORESETs which are configured with CORESET pool index values may effectively divide the CORESET into two or more groups. In cases where the UE  115 - a  indicates that it may be configured with CORESET pool index values for inter-slot and/or intra-slot PDCCH repetitions, the UE capability  210  may additionally indicate whether CORESET pool indexes for the first CORESET and the second CORESET that are associated with the linked search space sets for inter-slot and/or intra-slot PDCCH repetition may be the same, and/or if they may be different. 
     Additionally, or alternatively, in cases where the UE capability  210  indicates that the UE  115 - a  supports inter-slot and/or intra-slot PDCCH repetition (e.g., supports the second configuration  215 - b  and/or the third configuration  215 - c ), the UE capability  210  may additionally indicate whether the UE  115 - a  supports more than three CORESETs within an active BWP of a serving cell (and/or component carrier) supported by the base station  105 - a . For example, the UE capability  210  may indicate that the UE  115 - a  supports receipt of multiple related downlink control channel transmissions (e.g., PDCCH transmissions  220 ) which are associated with three or more CORESETs, where the three or more CORESETs are associated with a common BWP. In some aspects, the ability to support three (or more) CORESETs within a BWP may be applicable to a primary serving cell of the base station  105 - a . Moreover, in some implementations, the ability to support three (or more) CORESETs within a BWP may be applicable to only wireless communications performed within the FR2 frequency range. In particular, for FR2 communications, one CORESET may be dedicated for beam failure recovery (BFR), and one CORESET (e.g., CORESET0) may be dedicated for broadcast PDCCH (which generally utilize a wide beam). Thus, for FR2 communications in which three CORESETs are configured for a BWP, only one CORESET may be utilized for repetitions of downlink control channel transmissions (assuming that a narrow beams are to be used). 
     Furthermore, in cases where the UE capability  210  indicates that the UE  115 - a  supports inter-slot and/or intra-slot PDCCH repetition, the UE capability  210  may additionally indicate whether the UE  115 - a  supports span-based PDCCH monitoring within a serving cell configured for inter-slot and/or intra-slot PDCCH repetition. In particular, the UE capability  210  may indicate a maximum quantity of control channel candidates and/or CCEs (e.g., non-overlapping CCEs) per span of resources (e.g., span of time resources, span of frequency resources) which may be monitored or blindly decoded by the UE  115 - a . For example, the UE capability  210  may indicate that the UE  115 - a  supports monitoring of a quantity of control channel candidates per span of resources, a quantity of CCEs per span of resources, or both. In such cases, the UE capability  210  may indicate whether PDCCH repetitions may be monitored/decoded within a same span of resources, within different spans of resources, or both. 
     As noted previously herein, the UE  115 - a  may be able to decode multiple repetitions of related PDCCH transmissions  220  (e.g., first repetition of DCI, second repetition of DCI) by performing soft combining of the respective PDCCH transmissions  220 . As such, by supporting inter-slot and/or intra-slot PDCCH repetitions, the UE  115 - a  may be configured to store a soft output of a PDCCH candidate/repetition for a certain amount of time in order to combine the soft output with a later-received PDCCH candidate/repetition. The ability to store soft outputs of PDCCH repetitions may be particularly important in the context of inter-slot PDCCH repetitions (third configuration  215 - c ), in which the related/linked PDCCH repetitions are located in different slots  225 . For instance, the UE  115 - a  may only have the storage capacity and/or processing capability to store a soft output of a first repetition of a PDCCH transmission  220  for three slots  225 , and may therefore be unable to receive inter-slot PDCCH repetitions where the repetitions are separated by more than three slots  225 . 
     Accordingly, in cases where the UE capability  210  indicates that the UE supports receipt of inter-slot control channel repetitions (e.g., UE  115 - a  supports the third configuration  215 - c  for inter-slot PDCCH repetitions), the UE capability  210  may additionally indicate a quantity of slots  225  between linked/related downlink control channel transmissions which are capable of being blindly decoded. In particular, the UE capability  210  may indicate whether repetitions of PDCCH transmissions  220  may be received/decoded in contiguous slots  225 , non-contiguous slots  225 , or both. For example, the UE capability  210  may include an indication of a quantity of slots  225  (e.g., maximum quantity) between a first PDCCH transmission  220  and a second PDCCH transmission  220  associated with (e.g., related/linked to) the first PDCCH transmission  220  that are capable of being decoded by the UE  115 - a.    
     For instance, if the UE capability  210  indicates that a maximum quantity of slots  225  between linked PDCCH transmissions  220  is one, this may indicate that the UE  115 - a  supports inter-slot PDCCH repetitions only in contiguous (e.g., adjacent) slots  225 , whereas quantities of slots  225  between linked transmissions greater than one may indicate that the UE  115 - a  may support non-contiguous inter-slot PDCCH repetitions, contiguous inter-slot PDCCH repetitions, or both. In particular, if the UE capability  210  indicates that a maximum quantity of slots between linked PDCCH transmissions  220  is M, this may indicate that the UE  115 - a  may support inter-slot PDCCH repetition for (o s,2 −o s,1 ) mod k s ≤M, where k s  is the periodicity of a first and second linked search space set, o s,1  is the slot offset of the first search space set among the two linked search space sets, and o s,2  is the slot offset of the second search space set among the two linked search space sets. 
     Furthermore, in cases where the UE capability  210  indicates that the UE  115 - a  supports receipt of inter-slot control channel repetitions (e.g., UE  115 - a  supports the third configuration  215 - c  for inter-slot PDCCH repetitions), the UE capability  210  may additionally indicate a quantity (e.g., maximum quantity) of slots  225  in which a search space set exists within a search space set periodicity, where the search space set is linked with another search space set for inter-slot PDCCH repetition. In other words, the UE capability  210  may indicate a maximum search space set duration for sets of related search space sets which are linked for inter-slot PDCCH repetition. For example, the UE capability  210  may include an indication of a maximum number of slots  225  across which the UE  115 - a  supports one or more linked search space sets for inter-slot PDCCH repetitions in accordance with a search space set periodicity for the one or more linked search space sets. 
     Moreover, the UE capability  210  may indicate whether the UE  115 - a  may receive and/or decode PDCCH transmissions  220  which are received in overlapping search space sets. In particular, the UE capability  210  may indicate whether the UE  115 - a  may receive and/or decode PDCCH transmissions  220  which are received in monitoring occasions of one or more search space sets which overlap in the time domain, frequency domain, or both. For example, the UE capability  210  may indicate that the UE  115 - a  supports receipt of PDCCH transmissions  220  which are received within a first monitoring occasion of a first search space set, a second monitoring occasion of a second search space set, or both, where the first and second monitoring occasions at least partially overlap in the time domain, the frequency domain, or both. In some aspects, an ability of the UE  115 - a  to monitor search space sets/monitoring occasions which overlap in the time domain may enable the base station  105 - a  to determine applicable (e.g., allowable) values of the RRC parameter monitoringSymbolsWithinSlot for linked search space sets. Similarly, an ability of the UE  115 - a  to monitor search space sets/monitoring occasions which overlap in the frequency domain may enable the base station  105 - a  to determine applicable (e.g., allowable) configurations for two linked CORESETs which are associated with two linked search space sets for intra-slot PDCCH repetitions. 
     In some aspects, the various capabilities of the UE  115 - a  and/or parameters of the configurations supported by the UE  115 - a  may be indicated via the UE capability  210  at varying granularities. For example, the various capabilities of the UE  115 - a  and/or parameters of the configurations supported by the UE  115 - a  may be indicated for the UE  115 - a  (e.g., indicated on a per-UE  115  basis), may be indicated for each frequency band of the UE  115 - a  (e.g., indicated on a per-band basis), may be indicated for each frequency band combination of the UE  115 - a  (e.g., indicated on a per-band combination basis), may be indicated for each band of band combinations (e.g., on a per-feature set (FS) basis), may be indicated for each component carrier of a band of a band combination (e.g., indicated on a per-feature set per component carrier (FSPC) basis), or any combination thereof. 
     In some aspects, the UE  115 - a  may receive, from the base station  105 - a , a configuration  215  for receiving multiple related downlink control channel transmissions. In this regard, the UE  115 - a  may receive an indication of the first configuration  215 - a  for SFN PDCCH transmissions  220 , the second configuration  215 - b  for intra-slot PDCCH repetitions, the third configuration  215 - c  for inter-slot PDCCH repetitions, or any combination thereof. The configuration  215  may be indicated via control signaling, including RRC messages, DCI messages, MAC-CE messages, and the like. 
     In some aspects, the UE  115 - a  may receive the configuration  215  based on transmitting the UE capability  210 . In particular, the configuration  215  may be based on the one or more parameters or characteristics of the UE  115 - a  which were indicated via the UE capability  210 . Accordingly, the base station  105 - a  may configure the UE  115 - a  for SFN PDCCH transmissions  220 , intra-slot PDCCH repetitions, and/or inter-slot PDCCH repetitions (via the configuration  215 ) in accordance with the various capabilities or limitations of the UE  115 - a  which were indicated in the UE capability  210 . In other words, the base station  105 - a  may configure the UE  115 - a  with the configuration  215  for receiving multiple related PDCCH transmissions  220  which instructs the UE  115 - a  to monitor sets of resources, sets of related CORESETs, sets of related search space sets, sets of related monitoring occasions, or any combination thereof, for SFN PDCCH transmissions  220 , intra-slot PDCCH repetitions, inter-slot PDCCH repetitions, or any combination thereof. 
     For example, the configuration  215  may be based on any parameters or characteristics indicated in the UE capability  210  including, but not limited to, an ability to receive multiple related PDCCH transmissions  220  which are associated with three or more CORESETs that are associated with a common BWP, a quantity (e.g., maximum quantity) of slots between related PDCCH transmissions  220  that which are capable of being decoded by the UE  115 - a , an ability to receive/decode related PDCCH transmissions  220  within overlapping search space sets and/or overlapping monitoring occasions, a quantity of PDCCH monitoring occasions within one or more slots that are monitored by the UE  115 - a , an ability of the UE  115 - a  to monitor UE-specific and/or common search space sets, a format for PDCCH transmissions  220  (e.g., DCI format), parameters associated with CORESETs for intra-slot and/or inter-slot PDCCH repetitions, an ability of the UE  115 - a  to perform span-based monitoring, a quantity of CORESETs within a BWP, or any combination thereof. 
     For instance, in some cases, the UE capability  210  may indicate that the UE  115 - a  supports span-based monitoring. In such cases, the UE capability  210  may indicate that the UE  115 - a  supports monitoring of a quantity of control channel candidates per span of resources, a quantity of CCEs per span of resources, or both. In this example, the UE  115 - a  may receive the configuration  215  based on the quantities of control channel candidates and/or CCEs which may be monitored per span of resources, as indicated in the UE capability  210 . 
     In some aspects, the UE  115 - a  may receive an indication of one or more CORESETs  230  for receiving multiple related PDCCH transmissions  220 . The one or more CORESETs  230  may be indicated via control signaling, including RRC messages, DCI messages, MAC-CE messages, and the like. In some aspects, the UE  115 - a  may receive the indication of the one or more CORESETs  230  based on transmitting the UE capability  210 , receiving the configuration  215 , or both. Additionally, or alternatively, the indication of the one or more CORESETs  230  may be indicated along with the configuration  215 . In this regard, in some implementations, the configuration  215  and the CORESETs  230  may be indicated via a common control message (e.g., common RRC message, common DCI message). 
     In some aspects, the CORESETs  230  may be based on the one or more parameters or characteristics of the UE  115 - a  which were indicated via the UE capability  210 . Accordingly, the base station  105 - a  may configure the UE  115 - a  with one or more CORESETs  230  in accordance with the various capabilities or limitations of the UE  115 - a  which were indicated in the UE capability  210 . For example, the UE capability  210  may indicate whether the UE  115 - a  may support monitoring of two linked (e.g., related) CORESETs  230  in cases where the two linked CORESETs  230  have the same duration (e.g., same CORESET duration), different durations, or both. In such cases, the base station  105 - a  may configure the UE  115 - a  with a first CORESET  230  and a second CORESET  230  based on (e.g., in accordance with) the indication that CORESET durations of linked CORESETs  230  may be the same, different, or both. For instance, the UE capability  210  may indicate that the UE  115 - a  may receive intra-slot and/or intra-slot PDCCH repetitions associated with two linked CORESETs  230  which have different CORESET durations. In this example, the UE  115 - a  may receive an indication of a first CORESET  230  having a first CORESET duration (e.g., two symbols), and a second CORESET  230  having a second CORESET duration (e.g., three symbols), where the first CORESET  230  and the second CORESET  230  are linked for inter-slot and/or intra-slot PDCCH repetitions. 
     Similarly, the UE  115 - a  may receive an indication of one or more related search space sets  235 . The one or more related search space sets  235  may be indicated via control signaling, including RRC messages, DCI messages, MAC-CE messages, and the like. For example, the UE  115 - a  may receive an indication of a first search space set  235  and a second search space set  235 , where the first search space set  235  is related to (e.g., linked with) the second search space set  235 . In some aspects, the UE  115 - a  may receive the indication of the one or more search space sets  235  based on transmitting the UE capability  210 , receiving the configuration  215 , receiving the CORESETs  230 , or any combination thereof. Additionally, or alternatively, the indication of the one or more search space sets  235  may be indicated along with the configuration  215 , the CORESETs  230 , or both. In this regard, in some implementations, the configuration  215 , the CORESETs  230 , and the search space sets  235  may be indicated via a common control message (e.g., common RRC message, common DCI message). 
     In some implementations, the one or more search space sets  235  may be based on the one or more parameters or characteristics of the UE  115 - a  which were indicated via the UE capability  210 . Accordingly, the base station  105 - a  may configure the UE  115 - a  for with one or more search space sets  235  in accordance with the various capabilities or limitations of the UE  115 - a  which were indicated in the UE capability  210 . For example, in cases where the UE capability  210  indicates that the UE  115 - a  supports receipt of inter-slot PDCCH repetitions, the base station  105 - a  may transmit an indication of a first search space set  235  and a second search space set  235  associated with the first search space set  235 . In this example, the first and second search space sets  235  may each include one or more monitoring occasions in different slots  225  for inter-PDCCH repetition. For instance, the first search space set  235  may include a first monitoring in a first slot  225 - a , and the second search space set  235  may include a second monitoring occasion in a different slot  225  (e.g., second slot  225 - b , third slot  225 - c ), where the first and second monitoring occasions  235  are related or linked for inter-PDCCH repetitions. 
     By way of another example, the UE capability  210  may include indication of a quantity of slots  225  between a first PDCCH transmission  220  and a second PDCCH transmission  220  associated with the first PDCCH transmission  220  that are capable of being decoded by the UE  115 - a . For instance, the UE capability  210  may indicate that the UE  115 - a  may decode related PDCCH repetitions with up to three slots  225  between the related PDCCH repetitions for inter-slot PDCCH repetitions. In this example, the base station  105 - a  may configure the UE  115 - a  with a first search space set  235  and a second search space set  235  associated with the first search space set  235  in accordance with the indication of the quantity of slots  225 . In particular, in cases where the UE  115 - a  indicates a maximum quantity of M slots  225  between related PDCCH transmissions  220  which may be decoded by the UE  115 - a , the base station  105 - a  may configure the first and second search space sets  235  such that the monitoring occasions associated with the respective search space sets  235  are separated by no more than M slots  225 . 
     By way of another example, in cases where the UE capability  210  indicates that the UE  115 - a  supports receipt of intra-slot PDCCH repetitions (e.g., indicates support for the second configuration  215 - b ), the base station  105 - a  may transmit an indication of a first search space set  235  and a second search space set  235  associated with the first search space set  235 . In this example, the first and second search space sets  235  may each include one or more monitoring occasions in a common slot  225  for inter-PDCCH repetition. For instance, the first search space set  235  may include a first monitoring in a first slot  225 - a , and the second search space set  235  may include a second monitoring occasion in the first slot  225 - a , where the first and second monitoring occasions are related or linked for intra-PDCCH repetitions. In some aspects, sets of related or linked search space  235  sets and/or monitoring occasions for intra-slot PDCCH repetition may at least partially overlap in the time domain, the frequency domain, or both. In such cases, the base station  105 - a  may configure the UE  115 - a  with sets of overlapping search space sets  235  and/or overlapping monitoring occasions based on an indication, in the UE capability  210 , that the UE  115 - a  supports receipt of PDCCH transmissions  220  which are received in overlapping search space sets  235  and/or monitoring occasions. 
     In additional or alternative cases, the UE  115 - a  may receive the indication of the one or more search space sets  235  based on one or more additional parameters or characteristics indicated in the UE capability  210 , including a quantity of PDCCH monitoring occasions which may be monitored by the UE  115 - a , an indication that the UE  115 - a  supports monitoring of UE-specific search space sets  235  and/or common search space sets  235 , a DCI format associated with intra-slot and/or inter-slot PDCCH repetitions, or any combination thereof. 
     In some aspects, the UE  115 - a  may monitor a downlink control channel (e.g., PDCCH) in accordance with the configuration  215  for receiving multiple related downlink control channel transmissions. Moreover, the UE  115 - a  may monitor the control channel based on transmitting the UE capability  210 , receiving the configuration  215 , receiving the CORESETs  230 , receiving the search space sets  235 , or any combination thereof. 
     For example, in cases where the UE  115 - a  is configured with a first search space set  235  including a first monitoring occasion in a first slot  225 - a  and a second search space set  235  including a second monitoring occasion in a third slot  225 - c  for inter-slot PDCCH repetitions, the UE  115 - a  may monitor the first search space set  235  (e.g., first monitoring occasion), the second search space set (e.g., second monitoring occasion), or both, for inter-slot PDCCH repetitions in accordance with the configuration  215  and the search space sets  235 . Similarly, by way of another example, in cases where the UE  115 - a  is configured with a first search space set  235  including a first monitoring occasion in a first slot  225 - a  and a second search space set  235  including a second monitoring occasion in the first slot  225 - a  for intra-slot PDCCH repetitions, the UE  115 - a  may monitor the first search space set  235  (e.g., first monitoring occasion), the second search space set  235  (e.g., second monitoring occasion), or both, for intra-slot PDCCH repetitions in accordance with the configuration  215  and the search space sets  235 . 
     By way of another example, in cases where the UE capability  210  indicates that the UE  115 - a  supports receipt of SFN PDCCH transmissions  220 , the base station  105 - a  may configure the UE  115 - a  with a CORESET  230  including two TCI states at  315 . In this example, the UE  115 - a  may monitor the control channel (e.g., PDCCH) for SFN downlink control channel transmissions based on (e.g., in accordance with) the indication of the CORESET  230 . 
     In some aspects, the UE  115 - a  may receive, from the base station  105 - a , a first downlink control channel transmission (e.g., first PDCCH transmission  220 - a ). In some aspects, the base station  105 - a  may transmit the first PDCCH transmission  220 - a  according to a 5G radio access technology, an NR radio access technology, or both. In some aspects, the UE  115 - a  may receive the first PDCCH transmission  220 - a  based on monitoring the downlink control channel (e.g., PDCCH). Moreover, the UE  115 - a  may receive (and the base station  105 - a  may transmit) the first PDCCH transmission  220 - a  based on transmitting/receiving the UE capability  210 , transmitting/receiving the configuration  215 , transmitting/receiving the CORESETs  230 , transmitting/receiving the search space sets  235 , monitoring the downlink control channel, or any combination thereof. 
     Similarly, in some implementations, the UE  115 - a  may receive, from the base station  105 - a , a second downlink control channel transmission (e.g., second PDCCH transmission  220 - b ). In some aspects, the base station  105 - a  may transmit the second PDCCH transmission  220 - b  according to a 5G radio access technology, an NR radio access technology, or both. As noted previously herein, the second PDCCH transmission  220 - b  may be associated with (e.g., linked to, related with) the first PDCCH transmission  220 - a . For example, the first PDCCH transmission  220 - a  and the second PDCCH transmission  220 - b  may include repetitions of the same PDCCH transmission  220 , and may therefore include the same data payload. 
     In some aspects, the UE  115 - a  may receive the second PDCCH transmission  220 - b  based on monitoring the downlink control channel (e.g., PDCCH). Moreover, the UE  115 - a  may receive (and the base station  105 - a  may transmit) the second PDCCH transmission  220 - b  based on transmitting/receiving the UE capability  210 , transmitting/receiving the configuration  215 , transmitting/receiving the CORESETs  230 , transmitting/receiving the search space sets  235 , monitoring the downlink control channel, transmitting/receiving the first PDCCH transmission  220 - a , or any combination thereof. 
     For example, in cases where the UE capability  210  indicates that the first UE  115 - a  supports SFN PDCCH transmissions  220  (e.g., supports the first configuration  215 - a ), the UE  115 - a  may receive a configuration  215  for SFN PDCCH transmissions  220 . In this example, the UE  115 - a  may receive a first SFN PDCCH transmission  220 - a , and a second SFN PDCCH transmission  220 - b , in accordance with the configuration  215  for SFN PDCCH transmissions. By way of another example, in cases where the UE  115 - a  is configured for intra-slot PDCCH repetitions, the UE  115 - a  may receive a first PDCCH transmission  220 - a  within a first slot  225 - a , and may receive a second PDCCH transmission  220 - b  associated with (e.g., linked to, related with) the first PDCCH transmission  220 - a  within the same slot  225  (e.g., first slot  225 - a ). Similarly, in cases where the UE  115 - a  is configured for inter-slot PDCCH repetitions, the UE  115 - a  may receive a first PDCCH transmission  220 - a  within a first slot  225 - a , and may receive a second PDCCH transmission  220 - b  associated with (e.g., linked to, related with) the first PDCCH transmission  220 - b  within a third slot  225 - c  which is different from the first slot  225 - a.    
     In some aspects, UE  115 - a  may decode the first PDCCH transmission  220 - a , the second PDCCH transmission  220 - b , or both. In some aspects, the UE  115 - a  may decode the first PDCCH transmission  220 - a  and/or the second PDCCH transmission  220 - b  based on receiving the respective PDCCH transmissions  220 . Moreover, the UE  115 - a  may decode the first PDCCH transmission  220 - a  and/or the second PDCCH transmission  220 - b  based on transmitting the UE capability  210 , receiving the configuration  215 , receiving the CORESETs  230 , receiving the search space sets  235 , monitoring the downlink control channel, receiving the first PDCCH transmission  220 - a , receiving the second PDCCH transmission  220 - b , or any combination thereof. 
     For example, as noted previously herein, the first PDCCH transmission  220 - a  and the second PDCCH transmission  220 - b  may include repetitions of the same PDCCH transmission  220 , and may therefore include the same data payload. In this regard, the UE  115 - a  may be configured to decode (e.g., demodulate) the data payload of the respective PDCCH transmissions  220  by decoding the first PDCCH transmission  220 - a  or the second PDCCH transmission  220 - b . Additionally or alternatively, the UE  115 - a  may decode the data payload of the respective PDCCH transmissions  220  by performing a soft-combining procedure with both the first PDCCH transmission  220 - a  and the second PDCCH transmission  220 - b.    
     Techniques described herein may provide for improved scheduling of wireless communications. In particular, by enabling the UE  115 - a  to inform the network (e.g., base station  105 - a ) its capability to support one or more configurations for PDCCH repetition (e.g., SFN PDCCH transmissions  220 , inter-slot PDCCH repetitions, intra-slot PDCCH repetitions), techniques described herein may enable the base station  105 - a  to communicate with the UE  115 - a  using the respective configurations for PDCCH repetitions depending on the characteristics of the network (e.g., quantity of data traffic, noise) as well as the capabilities of the UE  115 - a . Thus, techniques described herein may enable more widespread use of communications using PDCCH repetitions within the wireless communications system, thereby improving a reliability of wireless communications, improving transmission diversity, and further protecting wireless communications against interference. 
       FIG. 3  illustrates an example of a process flow  300  that supports techniques for signaling user equipment capability for PDCCH repetition in accordance with aspects of the present disclosure. In some examples, process flow  300  may implement, or be implemented by, aspects of wireless communications systems  100 , wireless communications system  200 , or both. For example, the process flow  300  may illustrate a UE  115 - b  transmitting a UE capability to support receipt of multiple related downlink control channel transmissions, receiving a configuration for receiving multiple related downlink channel transmissions, and monitoring a downlink control channel in accordance with the configuration, as described with reference to  FIGS. 1-2 . 
     In some cases, process flow  300  may include a UE  115 - a , and a base station  105 - b , which may be examples of corresponding devices as described herein. In particular, the UE  115 - b  and the base station  105 - b  illustrated in  FIG. 3  may include examples of the UE  115 - a  and the base station  105 - a  illustrated in  FIG. 2 . 
     In some examples, the operations illustrated in process flow  300  may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components), code (e.g., software) executed by a processor, or any combination thereof. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added. 
     At  305 , the UE  115 - b  may transmit a UE capability indicating that the UE  115 - b  supports receipt of multiple related downlink control channel transmissions (e.g., multiple related PDCCH transmissions) which are associated with one or more CORESETs. In some aspects, the UE capability may be indicated via a UE capability report. In some aspects, the UE capability may indicate that it can receive and/or SFN downlink control channel transmissions (e.g., SFN PDCCH transmissions), intra-slot downlink control channel repetitions (e.g., intra-slot PDCCH repetitions), inter-slot downlink control channel repetitions (e.g., inter-slot PDCCH repetitions), or any combination thereof. In this regard, the UE capability may indicate that the UE  115 - b  supports a first configuration for receiving/decoding SFN PDCCH transmissions, a second configuration for receiving/decoding intra-slot PDCCH repetitions, and/or a third configuration for receiving/decoding inter-slot PDCCH repetitions. 
     In some cases, a network (e.g., wireless communications system  100 ,  200 ) may be configured with one or more standardized configurations for receiving/decoding multiple related downlink control channel transmissions. In such cases, the UE capability may indicate that the UE  115 - b  supports one or more of the configurations for receiving/decoding multiple related PDCCH transmissions via one or more bit field values of a UE capability report. 
     In some aspects, the UE capability may indicate that he UE supports receipt of SFN downlink control channel transmissions. In other words, the UE capability may indicate that the UE  115 - b  supports a first configuration for SFN PDCCH transmissions. As noted previously herein, in the context of SFN, each PDCCH transmission (e.g., PDCCH DMRS) may be associated with two TCI states. In such cases, the UE capability may include an indication of a quantity of CORESETs within a BWP which may be configured at the UE  115 - b . In particular, the UE capability may include an indication of a quantity of CORESETs within a BWP which may simultaneously be associated with two active TCI states. 
     In some cases, the UE capability may indicate that the UE supports receipt of inter-slot downlink control channel transmissions, intra-slot downlink control channel transmissions, or both. In other words, the UE capability may indicate that the UE  115 - b  supports a second configuration for intra-slot PDCCH repetitions, a third configuration for intra-slot PDCCH repetitions, or both. In such cases, the UE capability may include one or more parameters associated with intra-slot and/or inter-slot PDCCH repetitions which may be received/decoded by the UE  115 - b  including, but not limited to, quantities (e.g., maximum quantity) of downlink control channel monitoring occasions (e.g., PDCCH monitoring occasions) within one or more slots which may be monitored by the UE  115 - b , indications that the UE  115 - b  does or does not support monitoring of UE-specific search space sets and/or common search space sets, a format (e.g., DCI formats including DCI 1_0, DCI 2_0, DCI 3_0, etc.) for downlink control information associated with intra-slot and/or intra-slot downlink control channel repetitions, or any combination thereof. 
     For example, the UE capability may indicate a maximum number of PDCCH monitoring occasions within a slot which can be configured for a search space set that is linked with another search space set for inter-slot and/or intra-slot PDCCH repetitions. The indication of a maximum number of PDCCH monitoring occasions which may be monitored by the UE  115 - b  may determine allowable values of RRC parameters (e.g., monitoringSymbolsWithinSlot) which the base station  105 - b  may configure for the related/linked search space sets. By way of another example, the UE capability may indicate that the UE  115 - b  may receive and/or decode UE-specific search space sets and/or common search space sets for inter-slot PDCCH repetition, intra-slot PDCCH repetition, or both. By way of another example, the UE capability may indicate which DCI formats the UE  115 - b  may receive/decode for inter-slot and/or intra-slot PDCCH repetitions. In some aspects, the indication of the DCI format may determine allowable values for of RRC parameters (e.g., searchSpaceType) which the base station  105 - b  may configure for the related/linked search space sets. 
     The UE capability may indicate one or more parameters associated with sets of CORESETs which are linked for inter-slot and/or intra-slot PDCCH repetition. For example, the UE capability may indicate that the UE  115 - b  supports receipt of a first PDCCH transmission associated with a first CORESET, and a second PDCCH transmission associated with a second CORESET, where the first and second PDCCH transmissions are related or linked. In this example, the UE capability may indicate a first set of parameters associate with the first CORESET, and a second set of parameters associated with the second CORESET. In some cases, the first and second sets of parameters may be the same or different. The parameters associated with the respective CORESETs may include, but are not limited to, CORESET durations, CCE-REG mapping types, precoding granularity, CORESET pool indexes, or any combination thereof. 
     Additionally, or alternatively, in cases where the UE capability indicates that the UE  115 - b  supports inter-slot and/or intra-slot PDCCH repetition, the UE capability may additionally indicate whether the UE  115 - b  supports more than three CORESETs within an active BWP of a serving cell (and/or component carrier). For example, the UE capability may indicate that the UE  115 - b  supports receipt of multiple related downlink control channel transmissions which are associated with three or more CORESETs, where the three or more CORESETs are associated with a common BWP. 
     Furthermore, in cases where the UE capability indicates that the UE  115 - b  supports inter-slot and/or intra-slot PDCCH repetition, the UE capability may additionally indicate whether the UE  115 - b  supports span-based PDCCH monitoring within a serving cell configured for inter-slot and/or intra-slot PDCCH repetition. In particular, the UE capability may indicate a maximum quantity of control channel candidates and/or CCEs (e.g., non-overlapping CCEs) per span of resources (e.g., span of time resources, span of frequency resources) which may be monitored or blindly decoded. For example, the UE capability may indicate that the UE  115 - b  supports monitoring of a quantity of control channel candidates per span of resources, a quantity of CCEs per span of resources, or both. In such cases, the UE capability may indicate whether PDCCH repetitions may be monitored/decoded within a same span of resources, within different spans of resources, or both. 
     As noted previously herein, the UE  115 - b  may be able to decode multiple repetitions of related PDCCH transmissions (e.g., first repetition of DCI, second repetition of DCI) by performing soft combining of the respective PDCCH transmissions. As such, by supporting inter-slot and/or intra-slot PDCCH repetitions, the UE  115 - b  may be configured to store a soft output of a PDCCH candidate/repetition for a certain amount of time in order to combine the soft output with a later-received PDCCH candidate/repetition. The ability to store soft outputs of PDCCH repetitions may be particularly important in the context of inter-slot PDCCH repetitions, in which the related/linked PDCCH repetitions are located in different slots. For instance, the UE  115 - b  may only have the storage capacity and/or processing capability to store a soft output of a first repetition of a PDCCH transmission for three slots, and may therefore be unable to receive inter-slot PDCCH repetitions where the repetitions are separated by more than three slots. 
     Accordingly, in cases where the UE capability indicates that the UE supports receipt of inter-slot control channel repetitions (e.g., UE  115 - b  supports the second configuration for inter-slot PDCCH repetitions), the UE capability may additionally indicate a quantity of slots between linked/related downlink control channel transmissions which are capable of being blindly decoded. In particular, the UE capability may indicate whether repetitions of PDCCH transmissions may be received/decoded in contiguous slots, non-contiguous slots, or both. For example, the UE capability may include an indication of a quantity of slots (e.g., maximum quantity) between a first PDCCH transmission and a second PDCCH transmission associated with (e.g., related/linked to) the first PDCCH transmission that are capable of being decoded by the UE  115 - b . For instance, if the UE capability indicates that a maximum quantity of slots between linked PDCCH transmissions is one, this may indicate that the UE  115 - b  supports inter-slot PDCCH repetitions only in contiguous slots, whereas quantities of slots between linked transmissions greater than one may indicate that the UE  115 - b  may support non-contiguous inter-slot PDCCH repetitions, contiguous inter-slot PDCCH repetitions, or both. 
     Furthermore, in cases where the UE capability indicates that the UE  115 - b  supports receipt of inter-slot control channel repetitions (e.g., UE  115 - b  supports the third configuration for inter-slot PDCCH repetitions), the UE capability may additionally indicate a quantity (e.g., maximum quantity) of slots in which a search space set exists within a search space set periodicity, where the search space set is linked with another search space set for inter-slot PDCCH repetition. In other words, the UE capability may indicate a maximum search space set duration for sets of related search space sets which are linked for inter-slot PDCCH repetition. For example, the UE capability may include an indication of a maximum number of slots across which the UE  115 - b  supports one or more linked search space sets for inter-slot PDCCH repetitions in accordance with a search space set periodicity for the one or more linked search space sets. 
     Moreover, the UE capability may indicate whether the UE  115 - b  may receive and/or decode PDCCH transmissions which are received in overlapping search space sets. In particular, the UE capability may indicate whether the UE  115 - b  may receive and/or decode PDCCH transmissions which are received in monitoring occasions of one or more search space sets which overlap in the time domain, frequency domain, or both. For example, the UE capability may indicate that the UE  115 - b  supports receipt of PDCCH transmissions which are received within a first monitoring occasion of a first search space set, a second monitoring occasion of a second search space set, or both, where the first and second monitoring occasions at least partially overlap in the time domain, the frequency domain, or both. 
     In some aspects, the various capabilities of the UE  115 - b  and/or parameters of the configurations supported by the UE  115 - b  may be indicated via the UE capability at varying granularities. For example, the various capabilities of the UE  115 - b  and/or parameters of the configurations supported by the UE  115 - b  may be indicated for the UE  115 - b  (e.g., indicated on a per-UE  115  basis), may be indicated for each frequency band of the UE  115 - b  (e.g., indicated on a per-band basis), may be indicated for each frequency band combination of the UE  115 - b  (e.g., indicated on a per-band combination basis), may be indicated for each band of band combinations (e.g., on a per-FS basis), may be indicated for each component carrier of a band of a band combination (e.g., indicated on a per-FSPC basis), or any combination thereof. 
     At  310 , the UE  115 - b  may receive, from the base station  105 - b , a configuration for receiving multiple related downlink control channel transmissions. In this regard, the UE  115 - b  may receive an indication of a first configuration for SFN PDCCH transmissions, a second configuration for intra-slot PDCCH repetitions, a third configuration for inter-slot PDCCH repetitions, or any combination thereof. The configuration transmitted at  310  may be indicated via control signaling, including RRC messages, DCI messages, MAC-CE messages, and the like. 
     In some aspects, the UE  115 - b  may receive the configuration at  310  based on transmitting the UE capability at  305 . In particular, the configuration received at  310  may be based on the one or more parameters or characteristics of the UE  115 - b  which were indicated via the UE capability at  305 . Accordingly, the base station  105 - b  may configure the UE  115 - b  for SFN PDCCH transmissions, intra-slot PDCCH repetitions, and/or inter-slot PDCCH repetitions in accordance with the various capabilities or limitations of the UE  115 - b  which were indicated in the UE capability. In other words, the base station  105 - b  may configure the UE  115 - b  with the configuration for receiving multiple related PDCCH transmissions which instructs the UE  115 - b  to monitor sets of resources, sets of related CORESETs, sets of related search space sets, sets of related monitoring occasions, or any combination thereof, for SFN PDCCH transmissions, intra-slot PDCCH repetitions, inter-slot PDCCH repetitions, or any combination thereof. 
     For example, the configuration received at  310  may be based on any parameters or characteristics indicated in the UE capability including, but not limited to, an ability to receive multiple related PDCCH transmissions which are associated with three or more CORESETs that are associated with a common BWP, a quantity (e.g., maximum quantity) of slots between related PDCCH transmissions that which are capable of being decoded by the UE  115 - b , an ability to receive/decode related PDCCH transmissions within overlapping search space sets and/or monitoring occasions, a quantity of PDCCH monitoring occasions within one or more slots that are monitored by the UE  115 - b , an ability of the UE  115 - b  to monitor UE-specific and/or common search space sets, a format for PDCCH transmissions, parameters associated with CORESETs for intra-slot and/or inter-slot PDCCH repetitions, an ability of the UE  115 - b  to perform span-based monitoring, a quantity of CORESETs within a BWP, or any combination thereof. 
     For instance, in some cases, the UE capability may indicate that the UE  115 - b  supports span-based monitoring. In such cases, the UE capability may indicate that the UE  115 - b  supports monitoring of a quantity of control channel candidates per span of resources, a quantity of CCEs per span of resources, or both. In this example, the UE  115 - b  may receive the configuration based on the quantities of control channel candidates and/or CCEs which may be monitored per span of resources, as indicated in the UE capability. 
     At  315 , the UE  115 - b  may receive an indication of one or more CORESETs for receiving multiple related PDCCH transmissions. The one or more CORESETs may be indicated via control signaling, including RRC messages, DCI messages, MAC-CE messages, and the like. 
     In some aspects, the UE  115 - b  may receive the indication of the one or more CORESETs based on transmitting the UE capability at  305 , receiving the configuration at  310 , or both. Additionally, or alternatively, the indication of the one or more CORESETs indicated at  315  may be indicated along with the configuration at  310 . In this regard, in some implementations, the configuration at  310  and the CORESETs at  315  may be indicated via a common control message. 
     In some aspects, the CORESET received at  315  may be based on the one or more parameters or characteristics of the UE  115 - b  which were indicated via the UE capability at  305 . Accordingly, the base station  105 - b  may configure the UE  115 - b  with one or more CORESETs at  315  in accordance with the various capabilities or limitations of the UE  115 - b  which were indicated in the UE capability. For example, the UE capability may indicate whether the UE  115 - b  may support monitoring of two linked (e.g., related) CORESETs in cases where the two linked CORESETs have the same duration (e.g., same CORESET duration), different durations, or both. In such cases, the base station  105 - b  may configure the UE  115 - b  with a first CORESET and a second CORESET at  315  based on (e.g., in accordance with) the indication that CORESET durations of linked CORESETs may be the same, different, or both. For instance, the UE capability may indicate that the UE  115 - b  may receive intra-slot and/or intra-slot PDCCH repetitions associated with two linked CORESETs which have different CORESET durations. In this example, the UE  115 - b  may receive an indication of a first CORESET having a first CORESET duration (e.g., two symbols), and a second CORESET having a second CORESET duration (e.g., three symbols), where the first CORESET and the second CORESET are linked for inter-slot and/or intra-slot PDCCH repetitions. 
     At  320 , the UE  115 - b  may receive an indication of one or more related search space sets. The one or more related search space sets may be indicated via control signaling, including RRC messages, DCI messages, MAC-CE messages, and the like. For example, the UE  115 - b  may receive an indication of a first search space set and a second search space set, where the first search space set is related to (e.g., linked with) the second search space set. In some aspects, the UE  115 - b  may receive the indication of the one or more search space sets based on transmitting the UE capability at  305 , receiving the configuration at  310 , receiving the CORESETs at  315 , or any combination thereof. Additionally, or alternatively, the indication of the one or more search space sets indicated at  315  may be indicated along with the configuration at  310 , the CORESETs at  315 , or both. In this regard, in some implementations, the configuration at  310 , the CORESETs at  315 , and the search space sets at  320  may be indicated via a common control message. 
     In some aspects, the one or more search space sets received at  320  may be based on the one or more parameters or characteristics of the UE  115 - b  which were indicated via the UE capability at  305 . Accordingly, the base station  105 - b  may configure the UE  115 - b  for with one or more search space sets at  320  in accordance with the various capabilities or limitations of the UE  115 - b  which were indicated in the UE capability. For example, in cases where the UE capability indicates that the UE  115 - b  supports receipt of inter-slot PDCCH repetitions, the base station  105 - b  may transmit an indication of a first search space set and a second search space set associated with the first search space set. In this example, the first and second search space sets may each include one or more monitoring occasions in different slots for inter-PDCCH repetition. For instance, the first search space set may include a first monitoring in a first slot, and the second search space set may include a second monitoring occasion in a second slot, where the first and second monitoring occasions are related or linked for inter-PDCCH repetitions. 
     By way of another example, the UE capability transmitted at  305  may include indication of a quantity of slots between a first PDCCH transmission and a second PDCCH transmission associated with the first PDCCH transmission that are capable of being decoded by the UE  115 - b . For instance, the UE capability may indicate that the UE  115 - b  may decode related PDCCH repetitions with up to three slots between the related PDCCH repetitions for inter-slot PDCCH repetitions. In this example, the base station  105 - b  may configure the UE  115 - b  with a first search space set and a second search space set associated with the first search space set in accordance with the indication of the quantity of slots. In particular, in cases where the UE  115 - b  indicates a maximum quantity of M slots between related PDCCH transmissions which may be decoded by the UE  115 - b , the base station  105 - b  may configure the first and second search space sets such that the monitoring occasions associated with the respective search space sets are separated by no more than M slots. 
     By way of another example, in cases where the UE capability indicates that the UE  115 - b  supports receipt of intra-slot PDCCH repetitions, the base station  105 - b  may transmit an indication of a first search space set and a second search space set associated with the first search space set. In this example, the first and second search space sets may each include one or more monitoring occasions in a common slot for inter-PDCCH repetition. For instance, the first search space set may include a first monitoring in a first slot, and the second search space set may include a second monitoring occasion in the first slot, where the first and second monitoring occasions are related or linked for intra-PDCCH repetitions. In some aspects, sets of related or linked search space sets and/or monitoring occasions for intra-slot PDCCH repetition may at least partially overlap in the time domain, the frequency domain, or both. In such cases, the base station  105 - b  may configure the UE  115 - b  with sets of overlapping search space sets and/or overlapping monitoring occasions based on an indication, in the UE capability, that the UE  115 - b  supports receipt of PDCCH transmissions which are received in overlapping search space sets and/or monitoring occasions. 
     In additional or alternative cases, the UE  115 - b  may receive the indication of the one or more search space sets at  320  based on one or more additional parameters or characteristics indicated in the UE capability, including a quantity of PDCCH monitoring occasions which may be monitored by the UE  115 - b , an indication that the UE  115 - b  supports monitoring of UE-specific search space sets and/or common search space sets, a DCI format associated with intra-slot and/or inter-slot PDCCH repetitions, or any combination thereof. 
     At  325 , the UE  115 - b  may monitor a downlink control channel (e.g., PDCCH) in accordance with the configuration received at  310 . Moreover, the UE  115 - b  may monitor the control channel at  325  based on transmitting the UE capability at  305 , receiving the configuration at  310 , receiving the CORESETs at  315 , receiving the search space sets at  320 , or any combination thereof. 
     For example, in cases where the UE  115 - b  is configured with a first search space set including a first monitoring occasion in a first slot and a second search space set including a second monitoring occasion in a second slot for inter-slot PDCCH repetitions, the UE  115 - b  may monitor the first search space set (e.g., first monitoring occasion), the second search space set (e.g., second monitoring occasion), or both, for inter-slot PDCCH repetitions in accordance with the configuration received at  315  and the search space sets received at  320 . Similarly, by way of another example, in cases where the UE  115 - b  is configured with a first search space set including a first monitoring occasion in a first slot and a second search space set including a second monitoring occasion in the first slot for intra-slot PDCCH repetitions, the UE  115 - b  may monitor the first search space set (e.g., first monitoring occasion), the second search space set (e.g., second monitoring occasion), or both, for intra-slot PDCCH repetitions in accordance with the configuration received at  315  and the search space sets received at  320 . 
     By way of another example, in cases where the UE capability transmitted at  305  indicates that the UE  115 - b  supports receipt of SFN PDCCH transmissions, the base station  105 - b  may configure the UE  115 - b  with a CORESET including two TCI states at  315 . In this example, the UE  115 - b  may monitor the control channel (e.g., PDCCH) at  325  for SFN downlink control channel transmissions based on (e.g., in accordance with) the indication of the CORESET at  315 . 
     At  330 , the UE  115 - b  may receive, from the base station  105 - b , a first downlink control channel transmission (e.g., first PDCCH transmission). In some aspects, the base station  105 - b  may transmit the first PDCCH transmission at  330  according to a 5G radio access technology, an NR radio access technology, or both. In some aspects, the UE  115 - b  may receive the first PDCCH transmission at  330  based on monitoring the downlink control channel (e.g., PDCCH) at  325 . Moreover, the UE  115 - b  may receive (and the base station  105 - b  may transmit) the first PDCCH transmission at  330  based on transmitting/receiving the UE capability at  305 , transmitting/receiving the configuration at  310 , transmitting/receiving the CORESETs at  315 , transmitting/receiving the search space sets at  320 , monitoring the downlink control channel at  325 , or any combination thereof. 
     At  335 , the UE  115 - b  may receive, from the base station  105 - b , a second downlink control channel transmission (e.g., second PDCCH transmission). In some aspects, the base station  105 - b  may transmit the second PDCCH transmission at  335  according to a 5G radio access technology, an NR radio access technology, or both. As noted previously herein, the second PDCCH transmission may be associated with (e.g., linked to, related with) the first PDCCH transmission. For example, the first PDCCH transmission and the second PDCCH transmission may include repetitions of the same PDCCH transmission, and may therefore include the same data payload. 
     In some aspects, the UE  115 - b  may receive the second PDCCH transmission at  335  based on monitoring the downlink control channel (e.g., PDCCH) at  325 . Moreover, the UE  115 - b  may receive (and the base station  105 - b  may transmit) the second PDCCH transmission at  335  based on transmitting/receiving the UE capability at  305 , transmitting/receiving the configuration at  310 , transmitting/receiving the CORESETs at  315 , transmitting/receiving the search space sets at  320 , monitoring the downlink control channel at  325 , transmitting/receiving the first PDCCH transmission at  330 , or any combination thereof. 
     For example, in cases where the UE capability indicates that the first UE  115 - b  supports SFN PDCCH transmissions, the UE  115 - b  may receive a configuration for SFN PDCCH transmissions at  310 . In this example, the UE  115 - b  may receive a first SFN PDCCH transmission at  330 , and a second SFN PDCCH transmission at  335 , in accordance with the configuration received at  310 . By way of another example, in cases where the UE  115 - b  is configured for intra-slot PDCCH repetitions, the UE  115 - b  may receive a first PDCCH transmission within a slot at  330 , and may receive a second PDCCH transmission associated with (e.g., linked to, related with) the first PDCCH transmission within the same slot at  335 . Similarly, in cases where the UE  115 - b  is configured for inter-slot PDCCH repetitions, the UE  115 - b  may receive a first PDCCH transmission within a first slot at  330 , and may receive a second PDCCH transmission associated with (e.g., linked to, related with) the first PDCCH transmission within a second slot which is different from the first slot at  335 . 
     At  340 , the UE  115 - b  may decode the first PDCCH transmission, the second PDCCH transmission, or both. In some aspects, the UE  115 - b  may decode the first PDCCH transmission and/or the second PDCCH transmission at  340  based on receiving the respective PDCCH transmissions at  330  and/or  335 . Moreover, the UE  115 - b  may decode the first PDCCH transmission and/or the second PDCCH transmission at  340  based on transmitting the UE capability at  305 , receiving the configuration at  310 , receiving the CORESETs at  315 , receiving the search space sets at  320 , monitoring the downlink control channel at  325 , receiving the first PDCCH transmission at  330 , receiving the second PDCCH transmission at  335 , or any combination thereof. 
     For example, as noted previously herein, the first PDCCH transmission and the second PDCCH transmission may include repetitions of the same PDCCH transmission, and may therefore include the same data payload. In this regard, the UE  115 - b  may be configured to decode (e.g., demodulate) the data payload of the respective PDCCH transmissions by decoding the first PDCCH transmission or the second PDCCH transmission. Additionally, or alternatively, the UE  115 - b  may decode the data payload of the respective PDCCH transmissions by performing a soft-combining procedure with both the first PDCCH transmission and the second PDCCH transmission. 
     Techniques described herein may provide for improved scheduling of wireless communications. In particular, by enabling the UE  115 - b  to inform the network (e.g., base station  105 - b ) its capability to support one or more configurations for PDCCH repetition (e.g., SFN PDCCH transmissions, inter-slot PDCCH repetitions, intra-slot PDCCH repetitions), techniques described herein may enable the base station  105 - b  to communicate with the UE  115 - b  using the respective configurations for PDCCH repetitions depending on the characteristics of the network (e.g., quantity of data traffic, noise) as well as the capabilities of the UE  115 - b . Thus, techniques described herein may enable more widespread use of communications using PDCCH repetitions within the wireless communications system, thereby improving a reliability of wireless communications, improving transmission diversity, and further protecting wireless communications against interference.

     Additionally, or alternatively, in some examples, the communications manager  420 , the receiver  410 , the transmitter  415 , or various combinations or components thereof may be implemented in code (e.g., as communications management software) executed by a processor. If implemented in code executed by a processor, the functions of the communications manager  420 , the receiver  410 , the transmitter  415 , or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a central processing unit (CPU), a graphics processing unit (GPU), an ASIC, an FPGA, or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting a means for performing the functions described in the present disclosure). 
     In some examples, the communications manager  420  may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise in cooperation with the receiver  410 , the transmitter  415 , or both. For example, the communications manager  420  may receive information from the receiver  410 , send information to the transmitter  415 , or be integrated in combination with the receiver  410 , the transmitter  415 , or both to receive information, transmit information, or perform various other operations as described herein.

In particular, by enabling UEs  115  to inform the network (e.g., base station  105 ) of their capability to support one or more configurations for PDCCH repetition (e.g., SFN PDCCH transmissions, inter-slot PDCCH repetitions, intra-slot PDCCH repetitions), techniques described herein may enable the network to communicate with the UEs  115  using the respective configurations for PDCCH repetitions depending on the characteristics of the network (e.g., quantity of data traffic, noise) as well as the capabilities of the UEs  115 . Thus, techniques described herein may enable more widespread use of communications using PDCCH repetitions within the wireless communications system, thereby improving a reliability of wireless communications, improving transmission diversity, and further protecting wireless communications against interference.

     It should be noted that the methods described herein describe possible implementations, and that the operations and the steps may be rearranged or otherwise modified and that other implementations are possible. Further, aspects from two or more of the methods may be combined. 
     Although aspects of an LTE, LTE-A, LTE-A Pro, or NR system may be described for purposes of example, and LTE, LTE-A, LTE-A Pro, or NR terminology may be used in much of the description, the techniques described herein are applicable beyond LTE, LTE-A, LTE-A Pro, or NR networks. For example, the described techniques may be applicable to various other wireless communications systems such as Ultra Mobile Broadband (UMB), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, as well as other systems and radio technologies, including future systems and radio technologies, not explicitly mentioned herein. 
     Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof. 
     The various illustrative blocks and components described in connection with the disclosure herein may be implemented or performed with a general-purpose processor, a DSP, an ASIC, a CPU, a GPU, an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in the alternative, the processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration). 
     The functions described herein may be implemented in hardware, software executed by a processor, or any combination thereof. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, or functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. If implemented in software executed by a processor, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, hardwiring, or combinations of any of these. Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations. 
     Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, phase change memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium. Disk and disc, as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above are also included within the scope of computer-readable media. 
     As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of”) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (e.g., A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on.” As used herein, the term “and/or,” when used in a list of two or more items, means that any one of the listed items can be employed by itself, or any combination of two or more of the listed items can be employed. For example, if a composition is described as containing components A, B, and/or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination. 
     In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label, or other subsequent reference label. 
     The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration,” and not “preferred” or “advantageous over other examples.” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples. 
     The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
