Title: Channel state information enhancement with cross-link interference measurement

Description:
FIELD OF TECHNOLOGY 
     The following relates to wireless communications, including channel state information enhancement with cross-link interference measurement. 
     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). 
     SUMMARY 
     The described techniques relate to improved methods, systems, devices, and apparatuses that support channel state information enhancement with cross-link interference measurement. Generally, the described techniques provide for the allocation of a cross-link interference measurement resource (CL-IMR). In some examples, the CL-IMR resource may support cross-link interference (CLI) measurements using layer 1 procedures. A base station in communication with an “aggressor” user equipment (UE) and a “victim” UE may indicate a configuration for the CL-IMR to the victim UE, for example in one or both of the channel state information (CSI) report settings or CSI resource settings indicated in control signaling. The base station may also indicate, for example in downlink control information (DCI), to the aggressor UE, to transmit one or more reference signals in the same time-frequency resources as the CL-IMR. In some cases, the base station may schedule an aperiodic cross-link interference measurement in group-common DCI (e.g., joint triggering of the cross-link measurement). For example, the base station may transmit a common DCI indicating a timing for the aggressor UE to transmit one or more reference signals and the timing for the victim UE to perform the cross-link interference measurement using the configured CL-IMR. In some cases, the base station may provide the indications of the scheduling of an aperiodic cross-link interference measurement to the victim UE and the aggressor UE in separate DCI messages. The CL-IMR may be aperiodic, semi-persistent, or periodic. The CL-IMR may include one or more CSI reference signal resources which may be one-to-one mapped with channel measurement resources. In some examples, a victim UE may consider the CLI measurement through the CL-IMR when the victim UE calculates and reports channel state information to the base station. 
     A method for wireless communications at a first UE is described. The method may include receiving, from a base station, control signaling indicating one of a channel state information resource setting or a channel state information reporting setting, where a configuration for a cross-link interference measurement resource for performing a cross-link interference measurement of communications from a second UE to the base station is indicated in the channel state information resource setting or the channel state information reporting setting, performing the cross-link interference measurement of the communications from the second UE based on the configuration, and transmitting, to the base station, a report indicating the cross-link interference measurement.

     DETAILED DESCRIPTION 
     A user equipment (UE) may experience cross-link interference (CLI) attributable to signals transmitted by other UEs. For example, a “victim” UE may experience CLI from signals transmitted by an “aggressor” UE in cases where downlink resources of the victim UE overlap with uplink resources of the aggressor UE, thereby resulting in CLI. In some wireless communications systems, UEs may be configured to perform CLI measurements on signals received from other UEs, and report measured CLI to the network so that the network may adjust resources allocated to the respective UEs to reduce CLI. In some cases, base stations may coordinate the time and frequency resources of the aggressor UE&#39;s sounding reference signal (SRS) transmissions with the victim UE&#39;s CLI measurement resources in order to measure the CLI. Legacy CLI measurement and reporting may be based on layer-3 procedures. In some cases, however, the aggressor UE and victim UE may be in communication with the same cell (e.g., via a full-duplex base station), which may result in more dynamic cross-link interference. Current methods for measuring CLI may be unable to measure and respond to the dynamic CLI caused by an aggressor UE in communication with the same base station as the victim UE. 
     Aspects of the present disclosure support the allocation of a cross-link interference measurement resource (CL-IMR). In some examples, the CL-IMR resource may support CLI measurements using layer 1 procedures. A base station in communication with an aggressor UE and a victim UE may indicate a configuration for the CL-IMR to the victim UE, for example in one or both of the channel state information (CSI) report settings or CSI resource settings indicated in control signaling such as a radio resource control (RRC) message. The base station may also indicate, for example in another RRC message, to the aggressor UE, to transmit one or more reference signals (e.g., SRS(s)) in the same time-frequency resources as the CL-IMR. In some cases, the base station may schedule an aperiodic CLI measurement and reporting in group-common downlink control information (DCI) (e.g., joint triggering of the cross-link measurement). For example, the base station may transmit a common DCI indicating a timing and a resource for the aggressor UE to transmit one or more reference signals and the timing and the resource for the victim UE to perform the CLI measurement using the configured CL-IMR. In some cases, the base station may provide the indications of the scheduling of an aperiodic CLI measurement and reporting to the victim UE and a transmission of one or more reference signals to the aggressor UE in separate DCI (e.g., separate triggering). The CL-IMR may be aperiodic, semi-persistent, or periodic. The CL-IMR may include one or more resources which may be one-to-one mapped with channel measurement resources (CMRs). In some examples, a victim UE may consider the CLI measurement through the CL-IMR when the victim UE calculates and reports CSI to the base station (e.g., the CLI measurement may be taken into account when calculating a layer one reference signal received power, a layer one signal to interference and noise ratio, a precoding matrix index, a rank indicator, a channel quality indicator, or a layer one received signal strength indicator). 
     Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to wireless communications systems, resource configurations, 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 channel state information enhancement with cross-link interference measurement. 
       FIG.  1    illustrates an example of a wireless communications system  100  that supports channel state information enhancement with cross-link interference measurement 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. 
     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 . 
     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  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 . 
     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. 
     A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs  115  with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a lower-powered base station  105 , as compared with a macro cell, and a small cell may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs  115  with service subscriptions with the network provider or may provide restricted access to the UEs  115  having an association with the small cell (e.g., the UEs  115  in a closed subscriber group (CSG), the UEs  115  associated with users in a home or office). A base station  105  may support one or multiple cells and may also support communications over the one or more cells using one or multiple component carriers. 
     In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access for different types of devices. 
     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 support synchronous or asynchronous operation. For synchronous operation, the base stations  105  may have similar frame timings, and transmissions from different base stations  105  may be approximately aligned in time. For asynchronous operation, the base stations  105  may have different frame timings, and transmissions from different base stations  105  may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations. 
     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 such information to a central server or application program that makes use of the information or presents the information to humans interacting with the application program. Some UEs  115  may be designed to collect information or enable automated behavior of machines or other devices. 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. 
     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 (RBs)) 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 . 
     In some systems, the D2D communication link  135  may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs  115 ). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., base stations  105 ) using vehicle-to-network (V2N) communications, or with both. 
     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 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. 
     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 CSI 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. 
     A UE  115  may experience CLI attributable to signals transmitted by other UEs  115 . For example, a victim UE  115  may experience CLI from signals transmitted by an aggressor UE  115  in cases where downlink resources of the victim UE  115  overlap with uplink resources of the aggressor UE  115 , thereby resulting in CLI. A base station  105  in communication with an aggressor UE  115  and a victim UE  115  may indicate a configuration for the CL-IMR to the victim UE  115 , for example in one or both of the CSI report settings or CSI resource settings indicated in control signaling such as an RRC message. The base station  105  may also indicate (e.g., in an RRC message), to the aggressor UE  115 , to transmit one or more reference signals (e.g., SRS(s)) in the same time-frequency resources as the CL-IMR. In some cases, the base station  105  may schedule an aperiodic CLI measurement and reporting in group-common DCI (e.g., joint triggering of the cross-link measurement). For example, the base station  105  may transmit a common DCI indicating a timing and a resource for the aggressor UE  115  to transmit one or more reference signals and the timing and the resource for the victim UE  115  to perform the CLI measurement using the configured CL-IMR. In some cases, the base station  105  may provide the indications of the scheduling of an aperiodic CLI measurement and reporting to the victim UE  115  and the aggressor UE  115  in separate DCI (e.g., separate triggering). The CL-IMR may be aperiodic, semi-persistent, or periodic. The CL-IMR may include one or more resources which may be one-to-one mapped with CMRs. In some examples, a victim UE  115  may consider the CLI measurement through the CL-IMR when the victim UE  115  calculates and reports CSI to the base station  105  (e.g., the CLI measurement may be taken into account when calculating a layer one reference signal received power, a layer one signal to interference and noise ratio, a precoding matrix index, a rank indicator, a channel quality indicator, or a layer one received signal strength indicator). 
       FIG.  2    illustrates an example of a wireless communications system  200  that supports channel state information enhancement with cross-link interference measurement in accordance with aspects of the present disclosure. In some examples, wireless communications system  200  may implement, or may be implemented by, aspects of wireless communications system  100 . The wireless communications system  200  may include a first UE  115 - a , a second UE  115 - b , and a base station  105 - a , which may be examples of UEs  115  and base stations  105 , as described herein. 
     The first UE  115 - a  and the second UE  115 - b  may communicate with the base station  105 - a  using a communication link  205 - a  and a communication link  205 - b , respectively, which may be examples of NR or LTE links between the first UE  115 - a  and the second UE  115 - b , respectively, and the base station  105 - a . In some cases, the communication link  205 - a  and the communication link  205 - b  may include examples of access links (e.g., Uu links). The communication link  205 - a  and communication link  205 - b  may include bi-directional links that enable both uplink and downlink communication. For example, the first UE  115 - a  may transmit uplink signals, such as uplink control signals or uplink data signals, to the base station  105 - a  using the first communication link  205 - a  and the base station  105 - a  may transmit downlink signals, such as downlink control signals or downlink data signals, to the first UE  115 - a  using the communication link  205 - a . By way of another example, the second UE  115 - b  may transmit uplink signals, such as uplink control signals or uplink data signals, to the base station  105 - a  using the first communication link  205 - b  and the base station  105 - a  may transmit downlink signals, such as downlink control signals or downlink data signals, to the second UE  115 - b  using the communication link  205 - b . The first UE  115 - a  and the second UE  115 - b  may communicate with one another via a communication link  205 - c . In some cases, the communication link  205 - c  may include an example of a link between two UEs  115  (e.g., a sidelink communication link, or PC5 link). 
     As described herein, a victim UE  115  (e.g., first UE  115 - a ) may experience CLI which is attributable to signals transmitted by another nearby aggressor UE  115  (e.g., second UE  115 - b ). CLI may occur when the network (e.g., base station  105 - a ) configures multiple nearby UEs  115  with different TDD uplink and downlink slot formats. In particular, when an aggressor UE  115  (e.g., second UE  115 - b ) is transmitting uplink signals  235 , a nearby victim UE  115  (e.g., first UE  115 - a ) may receive the uplink signals  235  as CLI within its configured downlink symbols if uplink symbols of the aggressor UE  115 - b  collide with (e.g., overlap with) at least one downlink symbol of the victim UE  115 - a . The uplink signals transmitted by the aggressor UE  115 - b  may or may not be intended for the victim UE  115 - a , such that the victim UE  115 - a  inadvertently “intercepts” the uplink signals  235  intended for another wireless device (e.g., base station  105 - a ). 
     For example, as shown in  FIG.  2   , the first UE  115 - a  (e.g., victim UE  115 - a ) may experience CLI from signals  235  transmitted by the second UE  115 - b  (e.g., aggressor UE  115 - b ) in cases where downlink resources  215  of the first UE  115 - a  overlap with uplink resources  210  of the second UE  115 - b  (e.g., where an uplink symbol from the aggressor UE  115 - b  collides with a downlink symbol of the victim UE  115 - a ). In such cases, uplink transmissions  235  from second UE  115 - b  over the uplink resources  210  may collide with, or otherwise interrupt or interfere with, downlink transmissions received by the first UE  115 - a  within the downlink resources  215 , thereby resulting in CLI. CLI may occur between UEs  115  within the same cell (i.e., intra-cell) and/or between UEs  115  within different cells (i.e., inter cell). Inter cell CLI may be caused by semi-static time division duplex uplink and downlink configurations in the different cells. Intra-cell CLI may be caused by specific dynamic time division duplex uplink and downlink configurations inside the same cell. 
     Some wireless communications systems (e.g., wireless communications system  200 ) include CMRs to measure CSI, including defined signaling and procedures for the victim UE  115 - a  to measure CLI which is attributable to signals transmitted by the aggressor UE  115 - b . In this regard, the victim UE  115 - a  may be configured to perform CLI measurements attributable to signals received from other UEs  115  (e.g., aggressor UE  115 - b ). 
     For example. some UEs (e.g., UE  115 - a ) may include a framework including a linkage to one resource setting (e.g., CMR), a linkage to two resource settings (e.g., CMR and CSI interference measurement (CSI-IM) or non-zero power interference measurement resource (NZP-IMR)), or a linkage to three resource settings (e.g., CMR, CSI-IM and NZP-IMR). In some cases, each resource setting may be associated with one active resource set, and each resource set may include one or more resources (e.g., N resources). The UE  115 - a  may evaluate CSI corresponding to the N NZP-CMR resources and select one CMR resource out of the N resources, and the communication resource index corresponding to the selected CMR resource may be reported back to the base station  105 - a  as part of CSI feedback (e.g., the base station  105 - a  may use the report to associate the reported CSI with a given NZP-CMR resource). Accordingly, the base station  105 - a  may know which resources to use to communicate with the UE  115 - a.    
     For a CSI-IM resource, there may be a one-to-one mapping between each CMR (or each CSI hypothesis or each communication resource index) and each CSI-IM resource. For example, each CSI-RS resource for channel measurement may be resource-wise associated with a CSI-IM resource by the ordering of the CSI-RS resource and CSI-IM resource in the corresponding resource sets. The number of CSI-RS resources for channel measurement may be equal to the number of CSI-IM resources. The UE  115 - a  may measure interference by measuring the energy in the CSI-IM resource (e.g., with no reference signal estimation or measurement). The CSI-IM resource configuration may include REs for the UE  115 - a  to measure interference. NZP-IMR (e.g., non-zero power (NZP) CSI-RS resources for interference measurement) may be associated with all CMRs in a resource setting, unlike CSI-IM. Each NZP CSI-RS port configured for interference measurement may correspond to an interference transmission layer. The UE  115 - a  may estimate each port of the NZP CSI-RS resource for interference measurements, and each port may correspond to one interference transmission layer. A port of NZP-IMR may be beamformed and may be used for measuring multiple user interference. The NZP-IMR and CSI-IM may be quasi co-located (Type D) with the corresponding CMR resource. CSI-IM may be used to measure interference from neighboring cells, and NZP-IMR may be used to measure interference from UEs  115  within the same cell (e.g., in multiple user scenarios). 
       FIG.  3    illustrates an example of a resource configuration  300  that supports cross-link interference measurement in accordance with aspects of the present disclosure. In some examples, resource configuration  300  may implement, or be implemented by, aspects of wireless communications system  100 , wireless communications system  200 , or both. For example, the resource configuration  300  may illustrate a resource configuration for a victim UE  115 - c  and an aggressor UE  115 - d , which may be examples of UEs  115  and as described herein. 
     As shown, a victim UE  115 - c  may be configured to measure SRS  305  transmissions from an aggressor UE  115 - d . For example, a base station may configure the victim UE  115 - c , via DCI, to have the same SRS configuration  310  as the aggressor UE  115 - d  in order to measure the SRSs  305  transmitted by the aggressor UE  115 - d . The victim UE  115 - c  may calculate a reference signal received power of the SRS from the aggressor UE  115 - d  in order to calculate the CLI. An equivalent SRS resource configuration may be used for the aggressor and victim UEs  115 - d  and  115 - c  (e.g., an SRS resource  305  for transmission for the aggressor UE  115 - d  and an SRS resource  310  for measurement for the victim UE  115 - c . Some configuration parameters for the victim UE  115 - c  SRS configuration  310  and the aggressor UE  115 - d  SRS configuration  305  may differ due to carrier bandwidth, and the bandwidth parts  315  and  320  may not be aligned. The serving base stations of the victim UE  115 - c  and the aggressor UE  115 - d  may coordinate to configure the victim UE  115 - c  and the aggressor UE  115 - d  to use the same SRS configurations  305  and  310 . 
     A layer 3 CLI measurement procedure, as shown in resource configuration  300 , may be insufficient to support dynamic measurement and reporting of CLI in full-duplexing scenarios, for example when the victim UE  115 - c  and the aggressor UE  115 - d  are within a same cell and controlled by the same base station. 
     Returning to  FIG.  2   , a CL-IMR may be configured for a victim UE  115 - a  to measure CLI via control signaling  220 . The CL-IMR may be indicated within a report setting, such as within one or both of a CSI resource setting or a CSI report setting received from a base station  105 - a  in DCI. The CL-IMR may be aperiodic, semi-persistent, or periodic. 
     The time-frequency resource pattern of the CL-IMR may be equivalent to that of an SRS resource (or other reference signal for CLI measurement) transmitted by an aggressor UE  115 - b . For example, the base station  105 - a  may transmit control signaling  230  (e.g., via an RRC message) to the aggressor UE  115 - b  scheduling a reference signal transmission corresponding to the time-frequency resource pattern of the CL-IMR configured in the control signaling  220  transmitted to the victim UE  115 - a . In some cases, the base station  105 - a  may schedule an aperiodic CLI measurement via a control message  225 . In some examples, the base station  105 - a  may transmit a common DCI indicating a timing and a resource for the aggressor UE  115 - b  to transmit one or more reference signals and the timing and the resource for the victim UE  115 - a  to perform the CLI measurement using the configured CL-IMR. For example, the base station  105 - a  may transmit the messages  225  and  230  within a common DCI. In some cases, the base station  105 - a  may transmit the messages  225  and  230  scheduling an aperiodic CLI measurement to the victim UE  115 - a  and a transmission of one or more reference signals to the aggressor UE  115 - b  in separate DCI (e.g., separate triggering). 
     The victim UE  115 - a  may perform a CLI measurement on uplink signals  235  transmitted by the aggressor UE  115 - b  using the configured CL-IMR and report the measured CLI to the base station  105 - a  in a reporting message  240 . 
     The CL-IMR may include one or more resources which may be one-to-one mapped with CMRs. The CL-IMR may include a plurality of time-frequency resources, and each time-frequency resource of the CL-IMR may be one-to-one mapped to a resource of CMR. In some examples, each resource of CL-IMR may correspond to a different transmit beam of the aggressor UE  115 - b . In some examples, more than one aggressor UE  115  may cause CLI, and each resource of CL-IMR may correspond to a different transmit beam transmitted by each aggressor UE  115 . The CL-IMR may be configured with legacy IMRs, such as CSI-IM and NZP-IMR. The CL-IMR may be quasi co-located (Type D) with the corresponding CMR. In some examples, if the CMR is configured as an NZP-CSI-RS resource set with the higher layer parameter repetition set to “on” (e.g., CSI-RS for P3 beam management), the victim UE  115 - a  may assume that the SRS resources associated with the CL-IMR may be transmitted with the same transmit beam from the aggressor UE  115 - b . Accordingly, the victim UE  115 - a  may use that CMR to find a receive beam with lower CLI or a higher signal to interference and noise ratio (SINR). 
     In some examples, a victim UE  115 - a  may consider the CLI measurement through the CL-IMR when the victim UE  115 - a  calculates and reports CSI to the base station  105 - a  (e.g., the CLI measurement may be taken into account when calculating a layer one reference signal received power, a layer one signal to interference and noise ratio, a precoding matrix index, a rank indicator, a channel quality indicator, or a layer one received signal strength indicator). 
       FIG.  4    illustrates an example of a process flow  400  that supports channel state information enhancement with cross-link interference measurement in accordance with aspects of the present disclosure. In some examples, process flow  400  may implement, or be implemented by, aspects of wireless communications system  100 , wireless communications system  200 , or both. For example, base station  105 - b  may be an example of a base station  105  as described herein, and UE  115 - e  and UE  115 - f  may be examples of a UE  115  as described herein. 
     At  405 , the victim UE  115 - e  receives, from the base station  105 - b , control signaling indicating one or both of a CSI resource setting or a CSI reporting setting, where a configuration for a CL-IMR for performing a cross-link interference measurement of communications from the aggressor UE  115 - f  to the base station  105 - b  is indicated in one or both of the CSI resource setting or the CSI reporting setting. In some examples, the control signaling may be transmitted via an RRC message or a DCI message. 
     In some examples, the control signaling indicates the CL-IMR from a plurality of CSI resources. In some examples, the CL-IMR may include a plurality of time-frequency resources which may each be one-to-one mapped with a respective CMR of a plurality of CMRs. In some examples, each time-frequency resource of the CL-IMR may be quasi co-located (Type D) with the respective one-to-one mapped CMR of the plurality of CMRs. 
     In some examples, at  410  the base station  105 - b  may transmit, to the victim UE  115 - e , DCI indicating an aperiodic CLI measurement using the indicated CL-IMR. At  415 , the base station  105 - b  may transmit, to the aggressor UE  115 - f , control signaling scheduling a reference signal (e.g., an SRS) during a timing of the CL-IMR. In some examples, the base station  105 - b  may transmit the DCI at  410  and the control signaling at  415  scheduling an aperiodic CLI measurement in common DCI to both the victim UE  115 - e  and the aggressor UE  115 - f . In some examples, the base station  105 - b  may transmit the DCI at  410  and the control signaling at  415  scheduling an aperiodic CLI measurement in separate DCI messages. 
     At  420 , the aggressor UE  115 - f  may transmit an uplink transmission (e.g., a reference signal) scheduled by the base station  105 - b . At  425 , the victim UE  115 - e  may perform a CLI measurement on the uplink transmission using the CL-IMR. In some examples, the victim UE  115 - e  may measure a signal strength of a reference signal transmitted by the aggressor UE  115 - f  using the CL-IMR to measure the CLI. 
     In some examples, the control signaling received at  405  may indicate that the CL-IMR includes a plurality of time-frequency resources, and performing the CLI measurement at  425  may include measuring a plurality of beams transmitted by the aggressor UE  115 - f , where each beam of the plurality of beams may be measured via a respective time-frequency resource of the CL-IMR. In some examples, the control signaling received at  405  may indicate that the CL-IMR includes a plurality of time-frequency resources, and performing the CLI measurement at  425  may include measuring a plurality of beams transmitted by a plurality of aggressor UEs (where the plurality of aggressor UEs includes the aggressor UE  115 - f ), where each beam of the plurality of beams may be measured via a respective time-frequency resource of the CL-IMR. For example, the base station  105 - b  may configure the plurality of aggressor UEs to transmit reference signals during time periods associated with the time-frequency resources of the CL-IMR. 
     At  430 , the victim UE  115 - e  may transmit a report indicating the CLI measurement to the base station  105 - b . In some examples, the victim UE  115 - e  may calculate a CSI of a link between the victim UE  115 - e  and the base station  105 - b  based in part on the measured CLI, and transmitting the report at  430  may include transmitting the calculated CSI. In some examples, calculating the CSI may include calculating a layer one reference signal received power, a layer one signal to interference and noise ratio, a precoding matrix index, a rank indicator, a channel quality indicator, a layer one received signal strength indicator, or a 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.

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.
