Title: Techniques for scheduling full-duplex communications

Description:
FIELD OF TECHNOLOGY 
     The following relates to wireless communications, including techniques for scheduling full-duplex communications. 
     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 FDMA (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). 
     In some wireless communications systems, devices may be capable of performing full-duplex communications. Full-duplex communications may be associated with higher throughput, reduced latency, and greater spectral efficiency. However, some full-duplex communication schemes may also result in higher interference and decreased reliability. 
     SUMMARY 
     The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for scheduling full-duplex communications. Generally, the described techniques provide for performing full-duplex communications with reduced interference and greater reliability. In accordance with aspects of the present disclosure, a base station may identify an applicable restricted resource scheduling rule for restricting full-duplex operation on a first set of resources. The base station may transmit one or more control messages scheduling one or more full-duplex communications on a second set of resources based on the applicable restricted resource scheduling rule for restricting full-duplex operation on the first set of resources. In some examples, the second set of resources may overlap in time with the first set of resources. In other examples, the second set of resources may not overlap with the first set of resources in time or frequency. Accordingly, the base station may communicate the one or more full-duplex communications on the second set of resources. The described techniques may enable the base station to perform full-duplex communications with reduced interference and improved reliability, among other benefits.

     DETAILED DESCRIPTION 
     In some wireless communications systems, devices may be capable of performing full-duplex communications. For example, a base station may be capable of receiving an uplink message from a first user equipment (UE) while simultaneously transmitting a downlink message to a second UE. Full-duplex communications may be associated with higher throughput, reduced latency, and greater spectral efficiency. However, some full-duplex communication schemes may result in higher interference and decreased communication reliability. For example, if a base station attempts to transmit a downlink message to a first UE while simultaneously receiving an uplink message from a second UE in a same resource, transmission of the downlink message may interfere with reception of the uplink message. In some cases, this interference may result in decreased communication reliability at the base station. 
     Aspects of the present disclosure provide for performing full-duplex communications with greater reliability and decreased interference based on restricting devices from performing full-duplex communications on specific resources (e.g., time and frequency resources). For example, a base station may be restricted from scheduling full-duplex communications in specific time and frequency resources. Introducing full-duplex scheduling restrictions may result in lower interference and greater communication reliability, among other benefits. In some examples, the base station may be preconfigured with the full-duplex scheduling restrictions. Alternatively, the base station may receive scheduling information from a second base station, and may determine the full-duplex scheduling restrictions based on the scheduling information from the second base station. 
     In some examples, the base station may be unable to schedule full-duplex communications on a set of restricted resources. In other examples, the base station may schedule full-duplex communications on resources that overlap with the set of restricted resources (e.g., in the time-domain), provided that there is a guard band between the restricted resources and the scheduled resources. Including a guard band between the restricted resources and the scheduled resources may decrease the likelihood of leakage (e.g., interference) between the restricted resources and the scheduled resources. 
     In other examples, the base station may be configured with time and frequency resources that are dedicated to full-duplex communications. In such examples, the base station may be unable to schedule full-duplex communications outside of the dedicated resources. The techniques described herein may enable wireless devices (e.g., UEs and base stations) to perform full-duplex communications with reduced interference (e.g., self-interference, inter-UE interference, inter-base station interference) and greater communication reliability, among other benefits. 
     Aspects of the disclosure are initially described in the context of wireless communications systems, resource mappings, and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for scheduling full-duplex communications. 
       FIG.  1    illustrates an example of a wireless communications system  100  that supports techniques for scheduling full-duplex communications 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 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 tablet computer, a laptop computer, or a personal computer. 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. 
     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. 
     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 . 
     One or more numerologies for a carrier may be supported, where a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE  115  may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE  115  may be restricted to one or more active BWPs. 
     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, 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 . 
     Each base station  105  may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a base station  105  (e.g., over a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or others). In some examples, a cell may also refer to a geographic coverage area  110  or a portion of a geographic coverage area  110  (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the base station  105 . For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with geographic coverage areas  110 , among other examples. 
     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. 
     Some UEs  115  may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception simultaneously). In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs  115  include entering a power saving deep sleep mode when not engaging in active communications, operating over a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs  115  may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RB)) within a carrier, within a guard-band of a carrier, or outside of a carrier. 
     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). The UEs  115  may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, 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 a radio head, smart radio head, or transmission/reception point (TRP). 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 also operate in a super high frequency (SHF) region using frequency bands from 3 GHz to 30 GHz, also known as the centimeter band, or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), also known as the millimeter band. In some examples, the wireless communications system  100  may support millimeter wave (mmW) communications between the UEs  115  and the base stations  105 , and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate use of antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body. 
     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. 
     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). 
     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. 
     Some wireless communications systems may support full-duplex communications between wireless devices. For example, a wireless communications system may support simultaneous uplink and downlink transmission in a specific frequency range (e.g., frequency range 2 (FR2) or other frequency bands). The wireless communications system  100  may support full-duplex communications for IAB nodes or for access links between UEs  115  and base stations  105 . Both UEs  115  and base stations  105  may be capable of performing full-duplex communications. For example, a UE  115  or a base station  105  may perform uplink transmission and downlink reception using different antenna panels. 
     Full-duplex capabilities may depend on beam separation. In some examples, full-duplex communications may result in self-interference (e.g., between uplink and downlink operations), clutter echo, or both. However, full-duplex communications may also provide latency reduction. For example, a UE  115  may be able to receive a downlink signal in uplink slots, which may enable the UE  115  to experience latency savings. Full-duplex communications may also provide spectrum efficiency enhancements (e.g., per cell or per UE) and more efficient resource utilization. 
     Aspects of the present disclosure provide for restricting a base station  105  from scheduling full-duplex communications on specific resources. That is, the base station  105  may be restricted to scheduling full-duplex communications on a subset of time and frequency resources. Introducing full-duplex scheduling restrictions (e.g., restricted resource scheduling rules) may reduce inter-base station interference and inter-UE interference for critical channels and reference signals, and may ensure baseline performance. These full-duplex scheduling restrictions may be predefined, which may provide performance enhancements for deployments in which multiple operators share the same spectrum. Specifically, using predefined full-duplex scheduling restrictions may support aligned scheduling across multiple operators. 
     The wireless communications system  100  may support techniques for improved communication reliability and reduced interference, among other benefits. For example, the described techniques may provide for configuring a base station  105  with an applicable restricted resource scheduling rule. This applicable restricted resource scheduling rule may restrict the base station  105  from scheduling one or more full-duplex communications on a set of one or more restricted resources (e.g., one or more restricted resources  320  described with reference to  FIG.  3   ). Additionally or alternatively, the applicable restricted resource scheduling rule may restrict the base station  105  to scheduling one or more full-duplex communications on a set of one or more dedicated resources (e.g., one or more dedicated resources  330  described with reference to  FIG.  3   ). Configuring the base station  105  with a restricted resource scheduling rule may reduce interference levels on the set of one or more restricted resources and increase the likelihood of successful communications at the base station  105 . 
       FIG.  2    illustrates an example of a wireless communications system  200  that supports techniques for scheduling full-duplex communications in accordance with aspects of the present disclosure. The wireless communications system  200  may implement or be implemented by aspects of the wireless communications system  100 . For example, the wireless communications system  200  may include a UE  115 - a , a UE  115 - b , a base station  105 - a , and a base station  105 - b , which may be examples of corresponding devices described with reference to  FIG.  1   . The base stations  105  and the UEs  115  may communicate within a geographic coverage area  110 - a , which may be an example of a geographic coverage area  110  described with reference to  FIG.  1   . In the wireless communications system  200 , the base stations  105  may refrain from scheduling full-duplex communications on a set of restricted resources in accordance with a restricted resource scheduling rule. 
     The wireless communications system  200  may support different full-duplex use cases and types. Some example use cases of full-duplex may include full-duplex communications between one UE and two TRPs, full-duplex communications between one base station and two UEs, or full-duplex communications between one UE and one base station. For example, the UE  115 - a  may receive a downlink communication  210 - a  from the base station  105 - b  while simultaneously transmitting an uplink communication  215 - b  to the base station  105 - a . Likewise, the base station  105 - b  may receive an uplink communication  215 - d  from the UE  115 - b  while simultaneously transmitting a downlink communication  210 - a  to the UE  115 - a . Additionally or alternatively, the base station  105 - a  may transmit a downlink communication  210 - c  to the UE  115 - b  while simultaneously receiving an uplink communication  215 - c  from the UE  115 - b.    
     In the example of  FIG.  2   , the base stations  105  may identify an applicable restricted resource scheduling rule for restricting full-duplex operation on a set of one or more restricted resources (e.g., a first set of resources). The base stations  105  may identify the applicable restricted resource scheduling rule based on communicating control signaling  220  over-the-air (OTA) or over a backhaul connection such as an Xn interface or an F1 interface. The control signaling  220  may indicate the applicable restricted resource scheduling rule, the set of one or more restricted resources, slot format information associated with the base stations  105 , or a combination thereof. 
     After identifying the applicable restricted resource scheduling rule, the base stations  105  may transmit control messages  205  to the UEs  115 . For example, the base station  105 - a  may transmit a control message  205 - b  to the UE  115 - a , and may transmit a control message  205 - c  to the UE  115 - b . Similarly, the base station  105 - c  may transmit a control message  205 - a  to the UE  115 - a , and may transmit a control message  205 - d  to the UE  115 - b . The control messages  205  may schedule one or more full-duplex communications on a set of one or more available resources (e.g., a second set of resources). In some examples, the set of one or more available resources may not overlap with the set of restricted resources in time or frequency. In other examples, the set of one or more available resources may overlap in time with the set of one or more restricted resources if there is a guard band between the set of one or more available resources and the set of one or more restricted resources (e.g., if there are a threshold number of guard tones between the set of one or more available resources and the set of one or more restricted resources). In some examples, the set of one or more available resources may be dedicated for full-duplex communications. 
     Accordingly, the base stations  105  may perform the full-duplex communications (e.g., one or more full-duplex communications) with the UEs  115  on the set of one or more available resources. For example, the base station  105 - a  may transmit a downlink communication  210 - b  to the UE  115 - a  while simultaneously receiving an uplink communication  215 - b  from the UE  115 - a . Additionally or alternatively, the base station  105 - a  may transmit a downlink communication  210 - c  to the UE  115 - b  while simultaneously receiving an uplink communication  215 - c  from the UE  115 - b . Likewise, the base station  105 - b  may transmit a downlink communication  210 - a  to the UE  115 - a  while simultaneously receiving an uplink communication  215 - a  from the UE  115 - a . Additionally or alternatively, the base station  105 - b  may transmit a downlink communication  210 - d  to the UE  115 - b  while simultaneously receiving an uplink communication  215 - d  from the UE  115 - b.    
     The wireless communications system  200  may support techniques for improved communication reliability and reduced interference, among other benefits. For example, the described techniques may provide for configuring the base stations  105  with an applicable restricted resource scheduling rule. The applicable restricted resource scheduling rule may restrict the base stations  105  from scheduling one or more full-duplex communications on a set of one or more restricted resources (e.g., one or more restricted resources  320  described with reference to  FIG.  3   ). Additionally or alternatively, the applicable restricted resource scheduling rule may restrict the base stations  105  to scheduling full-duplex communications on a set of one or more dedicated resources (e.g., one or more dedicated resources  330  described with reference to  FIG.  3   ). Configuring the base stations with restricted resource scheduling rules may reduce interference levels on the set of one or more restricted resources and increase the likelihood of successful communications at the base stations  105 . 
       FIG.  3    illustrates an example of a resource mapping  300  that supports techniques for scheduling full-duplex communications in accordance with aspects of the present disclosure. The resource mapping  300  may implement or be implemented by aspects of the wireless communications system  100  or the wireless communications system  200 . For example, the resource mapping  300  may implement or be implemented by a base station or a UE, which may be examples of corresponding devices described with reference to  FIGS.  1  and  2   . In accordance with the resource mapping  300 , a base station may refrain from scheduling full-duplex communications on one or more restricted resources  320  based on a restricted resource scheduling rule. 
     For base stations that support full-duplex communications, scheduled full-duplex communications may have restrictions for a set of restricted time and frequency resources. The set of restricted time and frequency resources (e.g., the one or more restricted resources  320 ) may include RRC common downlink or uplink symbols, RRC dedicated downlink or uplink symbols, slot format indicator (SFI) downlink, uplink, or flexible symbols, synchronization signal block (SSB) resources, CORESETs configured for a common search space (CSS), remaining minimum system information (RMSI) or paging physical downlink shared channel (PDSCH) resources, resources configured for random access occasions, beam failure report (BFR) synchronization signal resources, BFR physical uplink control channel (PUCCH) resources, resources configured for scheduling requests, resources associated with a base station-coordinated (e.g., informed) slot or symbol pattern allowing or restricting full operations (e.g. via backhaul or OTA), or a combination thereof. 
     Additionally or alternatively, the set of restricted time and frequency resources (e.g., the one or more restricted resources  320 ) may include measurement gap resources, SSB-based measurement timing configuration (SMTC) resources, pilot reference signal resources, beam management reference signal resources, tracking reference signal (TRS) resources, sounding reference signal (SRS) resources, channel state information reference signal (CSI-RS) resources, phase tracking reference signal (PTRS) resources, resources for transmission or reception with repetition (e.g., slot aggregation), URLLC resources, semi-persistent scheduled (SPS) or configured grant resources, or a combination thereof. Restricted resource scheduling rules associated with these restricted time and frequency resources may be applicable to a base station, a UE connected to the base station, a neighboring cell of the base station, or a UE connected to the neighboring cell, among other examples. 
     In accordance with aspects of the present disclosure, a base station may be configured with an applicable restricted resource scheduling rule. In some examples, the applicable restricted resource scheduling rule may indicate that scheduled full-duplex resources (e.g., resources allocated for simultaneous transmission and reception) cannot overlap in time or frequency with the set of restricted time and frequency resources. These full-duplex scheduling restrictions may also indicate that a reverse direction transmission of an aggressor cell cannot overlap with an active BWP on RRC configured downlink or uplink symbols of a victim cell (e.g., where aggressor and victim cells can be the same or different). The aggressor cell may be defined as the cell with the highest SSB reference signal received power (RSRP) measurement from the victim cell above a threshold. In some examples, a base station can obtain slot format information for cells controlled by another base station via an Xn interface or an F1 interface. 
     In other examples, the applicable restricted resource scheduling rule may indicate that scheduled full-duplex resources can only overlap in time with the set of restricted resources (e.g., the one or more restricted resources  320 ) when a guard band between the scheduled full-duplex resources and the set of restricted resources includes a threshold number of guard tones (e.g., subcarriers). Alternatively, or additionally, the applicable restricted resource scheduling rule may define specific time and frequency resources (e.g., one or more dedicated resources  330 ) that are dedicated for only full-duplex communications. These dedicated time and frequency resources (e.g., the one or more dedicated resources  330 ) may include, for example, a dedicated BWP, dedicated symbols, dedicated slots, or a combination thereof. Additionally or alternatively, a defined (e.g., minimum) guard band between the scheduled full-duplex resources and the set of restricted resources may be defined to reduce leakage from the scheduled full-duplex resources to the set of restricted time and frequency resources. In other examples, a base station may utilize a combination of restricted resource scheduling rules discussed herein to make full-duplex scheduling decisions. 
     In the example of  FIG.  3   , a base station may schedule full-duplex communications based on an applicable restricted resource scheduling rule associated with one or more restricted resources  320 . The one or more restricted resources  320  (e.g., a first set of resources) may include multiple resources or a single resource (e.g., a single resource element, a single RB in a same symbol, a single slot). In some examples, the applicable restricted resource scheduling rule may restrict the base station from scheduling full-duplex communications on resources that overlap with the one or more restricted resources  320  in time or frequency. For example, the base station may be unable to schedule full-duplex communications on a resource that is in a restricted frequency range  305  (e.g., one or more BWPs, one or more resource elements, one or more resource blocks, one or more frequency bands. one or more frequency ranges, etc.). Similarly, the base station may be unable to schedule full-duplex communications on a resource that is in a restricted time period  310  (e.g., one or more symbol periods, one or more mini-slots, one or more slots, one or more subframes, one or more frames, etc.). 
     In some examples, the restricted resource scheduling rule may indicate that the base station may schedule full-duplex communications on any resources other than the one or more restricted resources  320 . For example, the base station may be able to schedule full-duplex communications on a resource  315 - a . In other examples, the applicable restricted resource scheduling rule may restrict the restricted resource scheduling rule may indicate that the base station may schedule full-duplex communications in the one or more dedicated resources  330  (e.g., time and frequency resources allocated for full-duplex communications). The one or more dedicated resources  330  (e.g., a second set of resources) may include multiple resources or a single resource (e.g., a single resource element, a single RB in a same symbol, a single slot). In such examples, the base station may schedule full-duplex communications on a dedicated resource  330 - a , but may be unable to schedule full-duplex communications on the resource  315 - a  (e.g., because the resource  315 - a  is not one of the dedicated resources  330 ). 
     In other examples, the restricted resource scheduling rule may indicate that the base station may schedule full-duplex communications on one or more resources that overlap with one or more restricted resources  320  as long as there is a guard band with a sufficient number of guard tones between the scheduled resource(s) and the restricted resource(s)  320 . For example, the base station may be able to schedule full-duplex communications on a resource  315 - b  if there is a guard band  325 - a  between the resource  315 - b  and a restricted resource  320 - a . Similarly, the restricted resource scheduling rule may indicate that the base station may schedule full-duplex communications on a dedicated resource  330 - b  as long as there is a guard band  325 - b  between the dedicated resource  330 - b  and a restricted resource  320 - b.    
     The resource mapping  300  may support techniques for improved communication reliability and reduced interference, among other benefits. For example, the described techniques may provide for configuring a base station with an applicable restricted resource scheduling rule. This applicable restricted resource scheduling rule may restrict the base station from scheduling one or more full-duplex communications on the one or more restricted resources  320  (e.g., a first set of resources). Additionally or alternatively, the applicable restricted resource scheduling rule may restrict the base station to scheduling full-duplex communications on the one or more dedicated resources  330  (e.g., a second set of resources). Configuring the base station with an applicable restricted resource scheduling rule may reduce interference levels on the one or more restricted resources  320  and increase the likelihood of successful communications at the base station. 
       FIG.  4    illustrates an example of a process flow  400  that supports techniques for scheduling full-duplex communications in accordance with aspects of the present disclosure. The process flow  400  may implement or be implemented by aspects of the wireless communications system  100  or the wireless communications system  200 . For example, the process flow  400  may include a UE  115 - c , a UE  115 - d , a base station  105 - c , and a base station  105 - d , which may be examples of corresponding devices described with reference to  FIGS.  1  and  2   . In the following description of the process flow  400 , operations between the UEs  115  and the base stations  105  may be performed in a different order or at a different time than as shown. Additionally or alternatively, some operations may be omitted from the process flow  400 , and other operations may be added to the process flow  400 . 
     In some examples, the base station  105 - c  may transmit control signaling to the base station  105 - d  at  405 . Likewise, the base station  105 - d  may transmit control signaling to the base station  105 - c  at  410 . The base stations  105  may communicate the control signaling over a backhaul link (e.g., an Xn interface or an F1 interface). In some examples, the control signaling may indicate slot format information associated with the base station  105 - d  or the base station  105 - c . Additionally or alternatively, the control signaling may indicate a first set of resources (e.g., one or more restricted resources  320  described with reference to  FIG.  3   ), an applicable restricted resource scheduling rule for restricting full-duplex operation on the first set of resources, or a combination thereof. 
     At  415 , the base station  105 - c  may identify the applicable restricted resource scheduling rule for restricting full-duplex operation on the first set of resources in full-duplex mode, as described with reference to  FIGS.  2  and  3   . The base station  105 - c  may identify the applicable restricted resource scheduling rule based on receiving control signaling from the base station  105 - d . For example, the base station  105 - c  may determine the applicable restricted resource scheduling rule based on receiving slot format information or an indication of an SSB-RSRP measurement from the base station  105 - d . In some examples, the applicable restricted resource scheduling rule may indicate a minimum guard band for the first set of resources. The applicable restricted resource scheduling rule may be applicable to any combination of the base stations  105  and the UEs  115 . 
     As described with reference to  FIGS.  2  and  3   , the first set of resources may include one or more of a common RRC downlink symbol, a common RRC uplink symbol, a dedicated RRC downlink symbol, a dedicated RRC uplink symbol, a resource associated with a downlink SFI configuration, a resource associated with an uplink SFI configuration, a resource associated with a flexible SFI configuration, a resource configured for transmission of an SSB, a CORSET for a CSS, a PDSCH resource configured for transmission of a paging message or RMSI, a resource configured for random access occasions, a resource configured for transmission of a BFR synchronization signal, a resource configured for transmission of a BFR PUCCH message, or a resource configured for transmission of a scheduling request, among other examples. 
     Additionally or alternatively, the first set of resources (e.g., one or more restricted resources) may include a set of resources associated with a slot pattern, a set of resources associated with a symbol pattern, a set of resources configured for full-duplex communications, a set of resources restricted from full-duplex communications, a set of resources configured for a measurement gap, a set of resources associated with an SMTC, a resource configured for pilot reference signal transmissions, a resource configured for beam management reference signal transmissions, a resource configured for TRS transmissions, a resource configured for SRS transmissions, a resource configured for CSI-RS transmissions, a set of resources configured for a transmission repetition, a set of resources configured for slot aggregation, a set of resources configured for URLLC, a set of resources configured for SPS transmissions or configured grant transmissions, or any combination thereof. In some examples, the first set of resources may correspond to an active BWP of the base station  105 - d  (e.g., a neighboring cell). 
     At  420 , the base station  105 - c  may transmit a first control message to the UE  115 - d . At  425 , the base station  105 - c  may transmit a second control message to the UE  115 - c . The first control message and the second control message may schedule one or more full-duplex communications on a second set of resources (e.g., one or more resources  315  or one or more dedicated resources  330  described with reference to  FIG.  3   ) based on the applicable restricted resource scheduling rule for restricting full-duplex operations on the first set of resources in full-duplex mode. In some examples, the second set of resources may not overlap with the first set of resources in time or frequency. In other examples, if there is a guard band between the first set of resources and the second set of resources, the second set of resources may at least partially overlap in time with the first set of resources. Additionally or alternatively, the second set of resources may be dedicated for full-duplex communications. 
     At  430 , the base station  105 - c  may communicate the one or more full-duplex communications with the UEs  115  in accordance with the first control message and the second control message. For example, the base station  105 - c  may transmit a downlink message to the UE  115 - d  while simultaneously receiving an uplink message from the UE  115 - c .

In some examples, the transmitter  515  may be co-located with a receiver  510  in a transceiver module. The transmitter  515  may utilize a single antenna or a set of multiple antennas. 
     The communications manager  520 , the receiver  510 , the transmitter  515 , or various combinations thereof or various components thereof may be examples of means for performing various aspects of techniques for scheduling full-duplex communications as described herein. For example, the communications manager  520 , the receiver  510 , the transmitter  515 , or various combinations or components thereof may support a method for performing one or more of the functions described herein.

In some examples, a processor and a memory coupled with the processor may be configured to perform one or more of the functions described herein (e.g., by executing, by the processor, instructions stored in the memory). 
     Additionally or alternatively, in some examples, the communications manager  520 , the receiver  510 , the transmitter  515 , or various combinations or components thereof may be implemented in code (e.g., as communications management software or firmware) executed by a processor. If implemented in code executed by a processor, the functions of the communications manager  520 , the receiver  510 , the transmitter  515 , or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a CPU, 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  520  may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise in cooperation with the receiver  510 , the transmitter  515 , or both.

     By including or configuring the communications manager  520  in accordance with examples as described herein, the device  505  (e.g., a processor controlling or otherwise coupled to the receiver  510 , the transmitter  515 , the communications manager  520 , or a combination thereof) may support techniques for reduced power consumption based on reducing a number of retransmissions performed by the device  505 . For example, the device  505  may refrain from scheduling full-duplex communications on a set of restricted resources, which may reduce interference caused by the full-duplex communications. Reducing the interference caused by the full-duplex communications may increase the likelihood of the full-duplex communications being successfully received. As such, the device  505  may perform fewer retransmissions of the full-duplex communications, which may result in greater power savings at the device  505 , among other benefits.

     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 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, 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, firmware, or any combination thereof. 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, firmware, 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, 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 (i.e., 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.” 
     The term “determine” or “determining” encompasses a wide variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database or another data structure), ascertaining and the like. Also, “determining” can include receiving (such as receiving information), accessing (such as accessing data in a memory) and the like. Also, “determining” can include resolving, selecting, choosing, establishing and other such similar actions. 
     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.
