Title: Inter-ue cross-link interference (cli) mitigation for base station in full duplex mode

Description:
BACKGROUND 
     Technical Field 
     The present disclosure relates generally to communication systems, and more particularly, to mitigation of cross-link interference (CLI) between user equipment (UEs) for base stations in full duplex mode. 
     Introduction 
     Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems. 
     These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.

     DETAILED DESCRIPTION 
     The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts. Although the following description may be focused on 5G NR, the concepts described herein may be applicable to other similar areas, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies. 
     Full duplex communication may allow a wireless communication device to transmit and receive at the same time. In-band full duplex (IBFD) may refer to transmission and reception on the same time and frequency resource. The uplink (UL) and the downlink (DL) may share the same IBFD time and frequency resource, which may include fully overlapping resources or partially overlapping resources. Sub-band frequency division duplexing (SBFD) may refer to transmission and reception at the same time on different frequency resources. The DL resource may be separated from the UL resource in the frequency domain. In an access network, a base station and/or a user equipment (UE) may be capable of either IBFD or SBFD. 
     The presence of full duplex devices in an access network may result in configurations with different types of interference experienced by a UE. Inter-cell interference may include interference from other gNBs and exist without the presence of full duplex devices. Channel state information (CSI) measurements may be used to measure inter-cell interference. Inter-cell cross-link interference (CLI) may occur between UEs in adjacent cells. Intra-cell CLI may occur between UEs in the same cell. For example, an uplink transmission from an aggressor UE may interfere with a downlink reception of a victim UE. In the case of a full-duplex UE, self-interference (SI) may be considered a special case of intra-cell CLI, where the transmitter of the UE acts as an aggressor UE that interferes with a downlink reception by the receiver of the UE. 
     Existing techniques for measuring CLI may not account for the effects of beam selection on CLI. Generally, the selection of a receive beam for the CLI measurements may be left to the UE. Accordingly, even if the base station receives a CLI report, the base station may not receive information about the CLI for different UE receive beams. Additionally, if existing CLI measurement procedures are extended to include measurements for specific beams, the number 
     In an aspect, the present disclosure provides for configuring a victim UE to generate a CLI report for multiple beams. The configuration of the CLI report may configure the UE with a set of measurement resources and identify a quasi-co-location (QCL) information associated with each measurement resource. The victim UE may measure interference metrics on the measurement resources using the beam indicated by the QCL for each respective measurement resource. For example, the interference metrics may be layer  1  (L 1 ) SRS RSRP or L 1  RSSI. In some implementations, the QCL information may change while a transmit beam for the measured reference signal remains constant. In other implementations, the QCL information may remain constant while the transmit beams for the measured reference signals change. In either case, the base station may configure the victim UE to generate a CLI report that provides information about CLI experienced on different receive beams. To reduce the overhead of the CLI report, the UE may include a subset of the interference metrics. For example, the UE may include interference metrics associated with reported measurement resources with less CLI than measurement resources that are not reported. The UE may identify the QCL information associated with the reported measurement resources. The report may allow the base station to identify beams or combination of beams that experience less CLI and may be suitable for communication. 
     Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
     By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on a chip (SoC), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. 
     Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer. 
       FIG.  1    is a diagram illustrating an example of a wireless communications system and an access network  100 . The wireless communications system (also referred to as a wireless wide area network (WWAN)) includes base stations  102 , UEs  104 , an Evolved Packet Core (EPC)  160 , and another core network (e.g., a 5G Core (5GC)  190 ). The UEs  104  may include an aggressor UE  104   a  and a victim UE  104   b.  The base stations  102  may include macrocells (high power cellular base station) and/or small cells (low power cellular base station). The macrocells include base stations. The small cells include femtocells, picocells, and microcells. 
     One or more of the UEs  104  (e.g., the victim UE  104   b ) may include a CLI component  140  that measures a CLI based on a configuration and reports the CLI to the base station  102 . The CLI component  140  may include a configuration component  142  configured to receive, from a base station, a configuration for cross-link interference (CLI) reporting associated with a plurality of measurement resources, the configuration identifying a quasi-co-location (QCL) information associated with each measurement resource. The CLI component  140  may include a measurement component  144  configured to measure interference metrics on the plurality of measurement resources based on the configuration for CLI reporting and the QCL information associated with each measurement resource. The CLI component  140  may include a reporting component  146  configured to transmit a CLI report to the base station, the CLI report including a subset of the interference metrics associated with reported measurement resources and identifying the QCL information associated with the reported measurement resources 
     In an aspect, one or more of the aggressor UEs  104   a  may include a sounding reference signal (SRS) component  198  configured to transmit an SRS, which may be used by the victim UE  104   b  for CLI measurements. As illustrated in further detail in  FIG.  13   , the SRS component  198  may include an SRS configuration component  1310  configured to receive, from a base station, a sounding reference signal (SRS) configuration corresponding to a plurality of cross-link interference (CLI) measurement resources for at least one victim UE, the SRS configuration identifying a transmission configuration indication (TCI) state spatial relation parameter and a panel for SRS transmission corresponding to each CLI measurement resource, and an SRS generator component  1320  configured to transmit an SRS using the TCI state spatial relation parameter, the panel, and a same SRS port on the CLI measurement resources. 
     In an aspect, one or more of the base stations  102  may include a scheduling component  120  that performs the actions of the base station as described herein (e.g., scheduling the scheduling victim UEs to measure CLI and aggressor UEs to transmit SRS. For example, the scheduling component  120  may include a CLI report scheduler  122  configured to transmit, to a victim UE, a configuration for cross-link interference (CLI) reporting associated with a plurality of measurement resources, the configuration identifying a quasi-co-location (QCL) information corresponding to each measurement resource. The scheduling component  120  may include a report component  124  configured to receive a CLI report including reported interference metrics for a subset of the measurement resources and associated QCL information corresponding to the reported interference metrics. The scheduling component  120  may optionally include an SRS scheduler  126  configured to transmit, to one or more aggressor UEs, an SRS configuration corresponding to the plurality of CLI measurement resources for the victim UE, the SRS configuration identifying a transmission configuration indication (TCI) state spatial relation parameter and a panel for SRS transmission corresponding to each CLI measurement resource. 
     The base stations  102  configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC  160  through backhaul links  132  (e.g., S1 interface). The backhaul links  132  may be wired or wireless. The base stations  102  configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) may interface with 5GC  190  through backhaul links  184 . The backhaul links  184  may be wired or wireless. In addition to other functions, the base stations  102  may perform one or more of the following functions: transfer of user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment trace, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations  102  may communicate directly or indirectly (e.g., through the EPC  160  or 5GC  190 ) with each other over backhaul links  134  (e.g., X2 interface). The backhaul links  134  may be wired or wireless. 
     The base stations  102  may wirelessly communicate with the UEs  104 . Each of the base stations  102  may provide communication coverage for a respective geographic coverage area  110 . There may be overlapping geographic coverage areas  110 . For example, the small cell  102 ′ may have a coverage area  110 ′ that overlaps the coverage area  110  of one or more macro base stations  102 . A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs), which may provide service to a restricted group known as a closed subscriber group (CSG). The communication links  112  between the base stations  102  and the UEs  104  may include uplink (UL) (also referred to as reverse link) transmissions from a UE  104  to a base station  102  and/or downlink (DL) (also referred to as forward link) transmissions from a base station  102  to a UE  104 . The communication links  112  may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and/or transmit diversity. The communication links may be through one or more carriers. The base stations  102 /UEs  104  may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL). The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell). 
     Certain UEs  104  may communicate with each other using device-to-device (D2D) communication link  158 . The D2D communication link  158  may use the DL/UL WWAN spectrum. The D2D communication link  158  may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), and a physical sidelink feedback channel (PSFCH). D2D communication may be through a variety of wireless D2D communications systems, such as for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR. 
     The wireless communications system may further include a Wi-Fi access point (AP)  150  in communication with Wi-Fi stations (STAs)  152  via communication links  154  in a 5 GHz unlicensed frequency spectrum. When communicating in an unlicensed frequency spectrum, the STAs  152 /AP  150  may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available. 
     The small cell  102 ′ may operate in a licensed and/or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell  102 ′ may employ NR and use the same 5 GHz unlicensed frequency spectrum as used by the Wi-Fi AP  150 . The small cell  102 ′, employing NR in an unlicensed frequency spectrum, may boost coverage to and/or increase capacity of the access network. 
     A base station  102 , whether a small cell  102 ′ or a large cell (e.g., macro base station), may include an eNB, gNodeB (gNB), or other type of base station. Some base stations, such as gNB  180  may operate in one or more frequency bands within the electromagnetic spectrum. 
     The electromagnetic spectrum is often subdivided, based on frequency/wavelength, into various classes, bands, channels, etc. In 5G NR two initial operating bands have been identified as frequency range designations FR 1  (410 MHz-7.125 GHz) and FR 2  (24.25 GHz-52.6 GHz). The frequencies between FR 1  and FR 2  are often referred to as mid-band frequencies. Although a portion of FR 1  is greater than 6 GHz, FR 1  is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR 2 , which is often referred to (interchangeably) as a “millimeter wave” (mmW) band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. 
     With the above aspects in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like if used herein may broadly represent frequencies that may be less than 6 GHz, may be within FR 1 , or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like if used herein may broadly represent frequencies that may include mid-band frequencies, may be within FR 2 , or may be within the EHF band. Communications using the mmW radio frequency band have extremely high path loss and a short range. The mmW base station  180  may utilize beamforming  182  with the UE  104  to compensate for the path loss and short range. 
     The base station  180  may transmit a beamformed signal to the UE  104  in one or more transmit directions  182 ′. The UE  104  may receive the beamformed signal from the base station  180  in one or more receive directions  182 ″. The UE  104  may also transmit a beamformed signal to the base station  180  in one or more transmit directions. The base station  180  may receive the beamformed signal from the UE  104  in one or more receive directions. The base station  180 /UE  104  may perform beam training to determine the best receive and transmit directions for each of the base station  180 /UE  104 . The transmit and receive directions for the base station  180  may or may not be the same. The transmit and receive directions for the UE  104  may or may not be the same. 
     The EPC  160  may include a Mobility Management Entity (MME)  162 , other MMEs  164 , a Serving Gateway  166 , a Multimedia Broadcast Multicast Service (MBMS) Gateway  168 , a Broadcast Multicast Service Center (BM-SC)  170 , and a Packet Data Network (PDN) Gateway  172 . The MME  162  may be in communication with a Home Subscriber Server (HSS)  174 . The MME  162  is the control node that processes the signaling between the UEs  104  and the EPC  160 . Generally, the MME  162  provides bearer and connection management. All user Internet protocol (IP) packets are transferred through the Serving Gateway  166 , which itself is connected to the PDN Gateway  172 . The PDN Gateway  172  provides UE IP address allocation as well as other functions. The PDN Gateway  172  and the BM-SC  170  are connected to the IP Services  176 . The IP Services  176  may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service, and/or other IP services. The BM-SC  170  may provide functions for MBMS user service provisioning and delivery. The BM-SC  170  may serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN), and may be used to schedule MBMS transmissions. The MBMS Gateway  168  may be used to distribute MBMS traffic to the base stations  102  belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and may be responsible for session management (start/stop) and for collecting eMBMS related charging information. 
     The 5GC  190  may include an Access and Mobility Management Function (AMF)  192 , other AMFs  193 , a Session Management Function (SMF)  194 , and a User Plane Function (UPF)  195 . The AMF  192  may be in communication with a Unified Data Management (UDM)  196 . The AMF  192  is the control node that processes the signaling between the UEs  104  and the 5GC  190 . Generally, the AMF  192  provides QoS flow and session management. All user Internet protocol (IP) packets are transferred through the UPF  195 . The UPF  195  provides UE IP address allocation as well as other functions. The UPF  195  is connected to the IP Services  197 . The IP Services  197  may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service, and/or other IP services. 
     The base station may also be referred to as a gNB, Node B, evolved Node B (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit reception point (TRP), or some other suitable terminology. The base station  102  provides an access point to the EPC  160  or 5GC  190  for a UE  104 . Examples of UEs  104  include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similar functioning device. Some of the UEs  104  may be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc.). The UE  104  may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.

FIG.  2 D  is a diagram  280  illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be FDD in which for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated for either DL or UL, or may be TDD in which for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated for both DL and UL. In the examples provided by  FIGS.  2 A,  2 C , the 5G NR frame structure is assumed to be TDD, with subframe  4  being configured with slot format  28  (with mostly DL), where D is DL, U is UL, and X is flexible for use between DL/UL, and subframe  3  being configured with slot format  34  (with mostly UL). While subframes  3 ,  4  are shown with slot formats  34 ,  28 , respectively, any particular subframe may be configured with any of the various available slot formats  0 - 61 . Slot formats  0 ,  1  are all DL, UL, respectively. Other slot formats  2 - 61  include a mix of DL, UL, and flexible symbols. UEs are configured with the slot format (dynamically through DL control information (DCI), or semi-statically/statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI). Note that the description infra applies also to a 5G NR frame structure that is TDD. 
     Other wireless communication technologies may have a different frame structure and/or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 7 or 14 symbols, depending on the slot configuration. For slot configuration  0 , each slot may include 14 symbols, and for slot configuration  1 , each slot may include 7 symbols. The symbols on DL may be cyclic prefix (CP) OFDM (CP-OFDM) symbols. The symbols on UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also referred to as single carrier frequency-division multiple access (SC-FDMA) symbols) (for power limited scenarios; limited to a single stream transmission). The number of slots within a subframe is based on the slot configuration and the numerology. For slot configuration  0 , different numerologies μ  0  to  5  allow for 1, 2, 4, 8, 16, and 32 slots, respectively, per subframe. For slot configuration  1 , different numerologies  0  to  2  allow for 2, 4, and 8 slots, respectively, per subframe. Accordingly, for slot configuration  0  and numerology μ, there are 14 symbols/slot and 2 μ  slots/subframe. The subcarrier spacing and symbol length/duration are a function of the numerology. The subcarrier spacing may be equal to 2 μ * 15 kHz, where μ is the numerology  0  to  5 . As such, the numerology μ=0 has a subcarrier spacing of 15 kHz and the numerology μ=5 has a subcarrier spacing of 480 kHz. The symbol length/duration is inversely related to the subcarrier spacing.  FIGS.  2 A- 2 D  provide an example of slot configuration  0  with 14 symbols per slot and numerology μ=0 with 1 slot per subframe. The subcarrier spacing is 15 kHz and symbol duration is approximately 66.7 μs. 
     A resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs)) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme. 
     As illustrated in  FIG.  2 A , some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include demodulation RS (DM-RS) (indicated as Rx for one particular configuration, where 100× is the port number, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS). 
       FIG.  2 B  illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE including nine RE groups (REGs), each REG including four consecutive REs in an OFDM symbol. A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE  104  to determine subframe/symbol timing and a physical layer identity. A secondary synchronization signal (SSS) may be within symbol  4  of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the aforementioned DM-RS. The physical broadcast channel (PBCH), which carries a master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS)/PBCH block. The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs), and paging messages. 
     As illustrated in  FIG.  2 C , some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. Although not shown, the UE may transmit sounding reference signals (SRS). The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL. 
       FIG.  2 D  illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and HARQ ACK/NACK feedback. The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and/or UCI. 
       FIG.  3    is a block diagram of a base station  310  in communication with a UE  350  in an access network. In the DL, IP packets from the EPC  160  may be provided to a controller/processor  375 . The controller/processor  375  implements layer  3  and layer  2  functionality. Layer  3  includes a radio resource control (RRC) layer, and layer  2  includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller/processor  375  provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression/decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization. 
     The transmit (Tx) processor  316  and the receive (Rx) processor  370  implement layer  1  functionality associated with various signal processing functions. Layer  1 , which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding/decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation/demodulation of physical channels, and MIMO antenna processing. The Tx processor  316  handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and/or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator  374  may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and/or channel condition feedback transmitted by the UE  350 . Each spatial stream may then be provided to a different antenna  320  via a separate transmitter  318 Tx. Each transmitter  318 Tx may modulate an RF carrier with a respective spatial stream for transmission. 
     At the UE  350 , each receiver  354 Rx receives a signal through its respective antenna  352 . Each receiver  354 Rx recovers information modulated onto an RF carrier and provides the information to the receive (Rx) processor  356 . The Tx processor  368  and the Rx processor  356  implement layer  1  functionality associated with various signal processing functions. The Rx processor  356  may perform spatial processing on the information to recover any spatial streams destined for the UE  350 . If multiple spatial streams are destined for the UE  350 , they may be combined by the Rx processor  356  into a single OFDM symbol stream. The Rx processor  356  then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT). The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station  310 . These soft decisions may be based on channel estimates computed by the channel estimator  358 . The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station  310  on the physical channel. The data and control signals are then provided to the controller/processor  359 , which implements layer  3  and layer  2  functionality. 
     The controller/processor  359  can be associated with a memory  360  that stores program codes and data. The memory  360  may be referred to as a computer-readable medium. In the UL, the controller/processor  359  provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the EPC  160  or 5GC  190 . The controller/processor  359  is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations. 
     Similar to the functionality described in connection with the DL transmission by the base station  310 , the controller/processor  359  provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression/decompression, and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization. 
     Channel estimates derived by a channel estimator  358  from a reference signal or feedback transmitted by the base station  310  may be used by the Tx processor  368  to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the Tx processor  368  may be provided to different antenna  352  via separate transmitters  354 Tx. Each transmitter  354 Tx may modulate an RF carrier with a respective spatial stream for transmission. 
     The UL transmission is processed at the base station  310  in a manner similar to that described in connection with the receiver function at the UE  350 . Each receiver  318 Rx receives a signal through its respective antenna  320 . Each receiver  318 Rx recovers information modulated onto an RF carrier and provides the information to a Rx processor  370 . 
     The controller/processor  375  can be associated with a memory  376  that stores program codes and data. The memory  376  may be referred to as a computer-readable medium. In the UL, the controller/processor  375  provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from the UE  350 . IP packets from the controller/processor  375  may be provided to the EPC  160 . The controller/processor  375  is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations. 
     At least one of the Tx processor  368 , the Rx processor  356 , and the controller/processor  359  may be configured to perform aspects in connection with the CLI component  140  and/or the SRS component  198  of  FIG.  1   . 
     At least one of the Tx processor  316 , the Rx processor  370 , and the controller/processor  375  may be configured to perform aspects in connection with the scheduling component  120  of  FIG.  1   . 
       FIGS.  4 A- 4 D  illustrate various modes of full-duplex communication. Full-duplex communication supports transmission and reception of information over a same frequency band in manner that overlap in time. In this manner, spectral efficiency may be improved with respect to the spectral efficiency of half-duplex communication, which supports transmission or reception of information in one direction at a time without overlapping uplink and downlink communication. Due to the simultaneous Tx/Rx nature of full-duplex communication, a UE or a base station may experience self-interference caused by signal leakage from its local transmitter to its local receiver. In addition, the UE or base station may also experience interference from other devices, such as transmissions from a second UE or a second base station. Such interference (e.g., self-interference or interference caused by other devices) may impact the quality of the communication, or even lead to a loss of information. 
       FIG.  4 A  shows a first example of full-duplex communication  400  in which a first base station  402   a  is in full duplex communication with a first UE  404   a  and a second UE  406   a.  The first base station  402   a  is a full-duplex base station, whereas the first UE  404   a  and the second UE  406   a  may be configured as either a half-duplex UE or a full-duplex UE. The second UE  406   a  may transmit a first uplink signal to the first base station  402   a  as well as to other base stations, such as a second base station  408   a  in proximity to the second UE  406   a.  The first base station  402   a  transmits a downlink signal to the first UE  404   a  concurrently with receiving the uplink signal from the second UE  406   a.  The base station  402   a  may experience self-interference at the receiving antenna that is receiving the uplink signal from UE  406   a  due to receiving some of the downlink signal being transmitted to the UE  404   a.  The base station  402   a  may experience additional interference due to signals from the second base station  408   a.  Interference may also occur at the first UE  404   a  based on signals from the second base station  408   a  as well as from uplink signals from the second UE  406   a.    
       FIG.  4 B  shows a second example of full-duplex communication  410  in which a first base station  402   b  is in full-duplex communication with a first UE  404   b.  In this example, the first base station  402   b  is a full-duplex base station and the first UE  404   b  is a full-duplex UE. The first base station  402   b  and the first UE  404   b  that can concurrently receive and transmit communication that overlaps in time in a same frequency band. The base station  402   b  and the UE  404   b  may each experience self-interference, in which a transmitted signal from the device is leaked to a receiver at the same device. The first UE  404   b  may experience additional interference based on one or more signals emitted from a second UE  406   b  and/or a second base station  408   b  in proximity to the first UE  404   b.  Additionally, the uplink transmissions from the first UE  404   b  may cause interference to the second UE  406   b  receiving downlink signals from the first base station  402   b  and/or the second base station  408   b.    
       FIG.  4 C  shows a third example of full-duplex communication  420  in which a first UE  404   c  is a full-duplex UE in communication with a first base station  402   c  and a second base station  408   c.  The first base station  402   c  and the second base station  408   c  may serve as multiple transmission and reception points (multi-TRPs) for UL and DL communication with the UE  404   c.  The second base station  408   c  may be in communication with a second UE  406   c.  In  FIG.  4 C , the first UE  404   c  may concurrently transmit an uplink signal to the first base station  402   c  while receiving a downlink signal from the second base station  408   c.  The first UE  404   c  may experience self-interference as a result of the first signal and the second signal being communicated simultaneously, e.g., the uplink signal may leak to, e.g., be received by, the UE&#39;s receiver. The first UE  404   c  may experience additional interference from the second UE  406   c.  Additionally, the uplink transmissions from the first UE  404   c  may cause interference to the second UE  406   c  receiving downlink signals from the first base station  402   c  and/or the second base station  408   c.    
       FIG.  4 D  shows a fourth example of full-duplex communication  430  in which one or more integrated access and backhaul (IAB) nodes  432   a,    432   b  are a full-duplex devices in communication with an JAB parent node  434  and one or more UEs  404 . Each full-duplex JAB node  432   a,    432   b  may experience self-interference, for example, from downlink transmissions to the UEs  404  (e.g., UEs  404   d,    404   e,    404   f,    404   g ) leaking into uplink signals from the UEs  404  or downlink signals from the JAB parent node  434 . Additionally, a full-duplex IAB node  432   a  may experience interference from downlink transmission of the JAB node  432   b  to UEs  404  or uplink transmissions of the JAB node  432   b  to the parent IAB node  434 . 
       FIG.  5    illustrates an example  500  of CLI measurement in the presence of full-duplex communication. For example, the base station  402   a  may be a full-duplex base station as in  FIG.  4 A  and communicate with a first UE  404   a  and a second UE  406   a.  The first UE  404   a  may receive a downlink signal  510  that is transmitted on a Tx beam  512  and received on a Rx beam  514 . Concurrently, the second UE  406   a  may transmit an uplink signal  520  on a Tx beam  522 , which is received by the base station  402   a  on a receive beam  524 . The uplink signal  520  may cause CLI  530  to the downlink signal  510  at the first UE  404   a,  which may be referred to as a victim UE. 
     The UE  404   a  may be configured with measurement resources for measuring the CLI  530 . For example, the measurement resources may correspond to an SRS transmitted by the UE  406   a.  Conventionally, however, the UE Rx beam for CLI measurement may be up to UE implementation. For example, the UE  404   a  may measure the CLI  530  using the Rx beam  514 . The UE  404   a  may report the CLI to the base station  402   a,  but the base station  402   a  may have no indication of what Rx beam the UE  404   a  used for the measurement. For example, if the Rx beam  514  experiences strong CLI, the UE  404   a  may not measure other Rx beams that may experience less CLI. Accordingly, the reported CLI measurements may not be particularly useful for selecting Rx beams that mitigate CLI. 
       FIG.  6    illustrates an example  600  of CLI measurement using multiple Rx beams in the presence of full-duplex communication. For example, the base station  402   a  may be a full-duplex base station as in  FIG.  4 A  and communicate with a first UE  404   a  and a second UE  406   a.  The first UE  404   a  may receive a downlink signal  610  that is transmitted on a Tx beam  612  and received on a Rx beam  614   a.  The first UE  404   a  may also have a candidate Rx beam  614   b  that may receive the downlink signal  610  via a path including a cluster  616 . Concurrently, the second UE  406   a  may transmit an uplink signal  620  on a Tx beam  622 , which is received by the base station  402   a  on a receive beam  624 . The uplink signal  620  may cause CLI  630  or CLI  632  to the downlink signal  610  at the first UE  404   a  depending on the Rx beam of the UE  404   a.    
     The UE  404   a  may be configured with measurement resources for measuring the CLI  630  and CLI  632 . For example, the measurement resources may correspond to an SRS transmitted by the UE  406   a  on the Tx beam  622 . The configuration of the measurement resources may specify the Rx beams  614   a  and  614   b  by associating a quasi-co-location (QCL) information with each measurement resource. The UE  404   a  may use the QCL information to separately measure the CLI  630  for Rx beam  614   a  and the CLI  632  for Rx beam  614   b.  The UE  406   a  may be configured to transmit the reference signal (e.g., SRS) using the same Tx beam  622  and/or SRS port. In the illustrated example, the Rx beam  614   b  may experience less CLI than the Rx beam  614   a.  The UE  404   a  may report the measured interference metrics and the QCL associated with each measurement resource to the base station  402   a.  The different reported interference metrics may allow the base station  402   a  to select beams that mitigate CLI, which may be in addition to other CLI mitigation techniques such as scheduling. 
       FIG.  7    illustrates an example  700  of CLI measurement using multiple Tx beams in the presence of full-duplex communication. For example, the base station  402   a  may be a full-duplex base station as in  FIG.  4 A  and communicate with a first UE  404   a  and a second UE  406   a.  The first UE  404   a  may receive a downlink signal  710  that is transmitted on a Tx beam  712  and received on a Rx beam  714 . Concurrently, the second UE  406   a  may transmit an uplink signal  720  on a Tx beam  722   a,  which is received by the base station  402   a  on a receive beam  724 . The second UE  406   a  may have a candidate beam  722   b  that can reach the base station  402   a  via a different path including a cluster  726 . The uplink signal  720  may cause CLI  730  or CLI  732  to the downlink signal  710  at the first UE  404   a  depending on the Tx beam of the UE  406   a.    
     The UE  404   a  may be configured with measurement resources for measuring the CLI  730  and CLI  732 . For example, the measurement resources may correspond to an SRS transmitted by the UE  406   a  on the Tx beams  722   a  and  722   b.  The configuration of the measurement resources may specify the Rx beams  714  by associating the same QCL information with each measurement resource. The UE  404   a  may use the QCL information to separately measure the CLI  730  for Tx beam  722   a  and the CLI  732  for Tx beam  722   b.  The UE  406   a  may be configured to transmit the reference signal (e.g., SRS) using the Tx beams  722   a  and  722   b  on different measurement resources. For example, each Tx beam  722   a,    722   b  may be associated with a different SRS port. In the illustrated example, the Tx beam  722   b  may generate less CLI than the Tx beam  722   a.  The UE  404   a  may report the measured interference metrics and the QCL associated with each measurement resource to the base station  402   a.  The different reported interference metrics may allow the base station  402   a  to select beams that mitigate CLI, which may be in addition to other CLI mitigation techniques such as scheduling. 
       FIG.  8    illustrates an example  800  of CLI measurement using multiple beams and multiple panels  840   a,    842   a  in the presence of full-duplex communication. Generally, a panel may be a component of a UE or base station including an antenna group including one or more antennas and associated with a panel ID. An antenna may include one or more antennas, antenna elements, and/or antenna arrays. Each panel may operate with a degree of independence. Each panel may be configured with a different panel identifier (panel ID). In an aspect, a panel may be associated with an antenna group. In an aspect, a panel may be a unit of an antenna group to control beams independently. The selection of a panel at the UE may have a similar effect to selection of a beam. The Tx beam or the Rx beam to be used may be specified via a configuration of reference signals (e.g., SRS configuration) for uplink or CSI-RS configuration for downlink. The panel  840   a,    842   a  to use for measurements, however, may be up to UE implementation. For CLI measurement, the interference metrics may be relevant to a beam pair selected by the victim UE and the aggressor UE. 
     For example, the UE  404   a  may be configured with a DL RS (e.g., QCL information) for measuring CLI  830 . If the victim UE  404   a  includes two panels  840   a  and  842   a,  the DL RS may be associated with a first Rx beam  814   a  and a second Rx beam  814   b  for receiving DL signal  810  from DL Tx beam  812 . Similarly, the aggressor UE  404   b  may be configured with a DL RS (e.g., SRS configuration). If the aggressor UE  406   a  includes two panels  840   b,    842   b,  the DL RS may be associated with a first Tx beam  822   a  and a second Tx beam  822   b  for transmitting UL signal  820  to be received on UL Rx beam  824 . Table  850  illustrates the different possible beam combinations using the same DL RS but different panels. 
     In an aspect, a CLI measurement may be identified by both a beam indication RS and a UE panel identifier. For example, each measurement resource for CLI  830  may be associated with a beam indication RS and a UE panel identifier for both transmit and receive sides. The UE panel identifier may be, for example, a panel ID, an antenna group ID, or an SRS resource set ID where each set is mapped to a panel and each SRS resource within the set is mapped to a beam of the panel. For instance, at the aggressor UE  406   a  using a panel ID, the Tx beams  822   a  and  822   b  may be transmitted on SRS resources whose beams are indicated by the same DL RS plus a panel ID (e.g.,  0  or  1 ). At the aggressor UE  406   a  using an SRS resource set, the Tx beams  822   a  and  822   b  may be transmitted on SRS resources that have a same beam indication RS and are in different SRS resource sets mapped to panel ID  0  (panel  840   b ) and panel ID  1  (panel  842   b ). At the victim UE  404   a  using a panel ID, the Rx beams  814   a  and  814   b  may be indicated by the same QCL information (e.g., QCL-TypeD RS) plus a panel ID (e.g.,  0  or  1 ). At the victim UE  404   a  using an SRS resource set ID, the QCL information for the Rx beams  814   a  and  814   b  may be mapped to SRS resources that have the same beam indication RS, but are in different SRS sets mapped to panel ID  0  (panel  840   a ) or panel ID  1  (panel  842   a ). 
       FIG.  9    is a diagram  900  illustrating examples of transmit beam repetition on the same port. Repetition of the transmit beam on the same port may allow a receiving device to compare measured CLI from the same port on different receive beams. Conventionally, each SRS resource may be associated with one symbol and one port, but the base station does not specify whether CLI resources are from the same port. 
     In a first example  910 , the base station may indicate for an aggressor UE  406   a  to transmit 
     SRS using the same port over measurement resources  912  (e.g.,  912   a,    912   b,  . . . ,  912   n ) configured for CLI measurement by the victim UE  404 . For example, the base station may transmit an RRC message (e.g., an SRS configuration) including a parameter indicating whether SRS repetition is On or Off for each measurement resource. If the repetition parameter is set to On, each SRS resource in the configured SRS resource set may be transmitted with the same spatial filter and port. Accordingly, the victim UE  404   a  may receive the same beam  914  on each measurement resource  912 . 
     In a second example  920 , the base station may indicate for an aggressor UE  406   a  to transmit SRS on multiple sub-resources  922  (e.g., symbols  922   a,    922   b,    922   n ) of a measurement resource  912  using the same port. The base station may also configure the aggressor UE  406   a  for no hopping (e.g., R=N_symbol) such that the same port is transmitted on the same set of subcarriers per symbol without hopping across symbols. Accordingly, the victim UE  404   a  may receive the same beam  924  on each measurement sub-resource  922 . 
     In an aspect, the SRS may be configured to mimic uplink transmissions such as PUSCH and PUCCH such that CLI measurements may be used by the base station in making beam selection and scheduling decisions for future slots. In general, the power control and Tx power for SRS are different from PUSCH. For example, PUSCH transmission power may be represented by the following expression.

     The SRS power control adjustment h(.) may be adapted to mimic PUSCH power control. For example, h(.) may equal f(.) if srs-PowerControlAdjustmentStates indicates a same power state for both SRS and PUSCH, but may otherwise vary. In an aspect, the SRS power control adjustment may be configured to re-use a PUCCH closed loop index instead of a PUSCH closed loop index. Accordingly, in an aspect, the present disclosure provides for CLI measurements that mimic interference from PUCCH transmissions. 
       FIG.  10    is a message diagram  1000  illustrating example messages for CLI reporting for multiple beams. A base station  102  may be a serving base station for an aggressor UE  104   a  and a victim UE  104   b.

       FIG.  11    is a conceptual data flow diagram  1100  illustrating the data flow between different means/components in an example base station  1102 , which may be an example of the base station  102  including the scheduling component  120 . The scheduling component  120  may include the CLI report scheduler  122  and the report component  124 . The scheduling component  120  may optionally include the SRS scheduler  126 . 
     The base station  1102  may also may include a receiver component  1150  and a transmitter component  1152 . The receiver component  1150  may include, for example, a RF receiver for receiving the signals described herein.

In some implementations, the receiver component  1150  and the transmitter component  1152  may be co-located in a transceiver such as the Tx/Rx  318  in  FIG.  3   . 
     The receiver component  1150  may receive uplink signals from multiple UEs  104 . For example, the receiver component  1150  may receive an SRS from the aggressor UE  104   a  and a CLI report from the victim UE  104   b.  The receiver component  1150  may provide the CLI report to the report component  124 .

The CLI report scheduler  122  may configure the one or more victim UEs to transmit a CLI report  1050  based on the measured CLI. In particular, the CLI report scheduler  122  may transmit the CLI report configuration  1032  indicating one or more properties of the CLI report as described herein. For example, the CLI report configuration  1032  may identify a QCL information  1036  corresponding to each measurement resource  1034 . The panel  1038  may be identified by one of a panel ID, antenna group ID, or SRS resource set ID. In some implementations, the CLI report configuration may indicate a panel  1038  for each measurement resource. The CLI report may be associated with one or more CSI-IM resource sets corresponding to an SRS transmission of an aggressor UE  104   a.    
     The SRS scheduler  126  may receive an indication of the CLI measurement resources from the CLI report scheduler  122 . The SRS scheduler  126  may be configured to transmit, to one or more aggressor UEs, an SRS configuration  1022  corresponding to a plurality of CLI measurement resources for a victim UE. For example, the SRS scheduler  126  may transmit an SRS configuration  1022  as RRC signaling  1020  via the transmitter component  1152 . The SRS configuration may identify an SRS resource set  1023 , TCI state  1024  spatial relation parameter, and a panel  1026  for SRS transmission corresponding to each CLI measurement resource. In some implementations, the SRS configuration includes an SRS resource set  1023  including a plurality of SRS resources transmitted with a same spatial filter and port. For instance, the SRS configuration may be an RRC message that indicates repetition  1028  of an SRS signal per SRS resource set. In some implementations, the SRS configuration includes an SRS resource including multiple symbols corresponding to different receive beams of the victim UE and the SRS transmission is configured for no hopping across frequency. In some implementations, the SRS configuration  1022  indicates an SRS transmission power based on a closed loop index for a physical uplink control channel. 
     The report component  124  may receive a CLI report  1050  from one or more victim UEs  104 . The CLI report  1050  may include reported interference metrics for a subset of the measurement resources and associated QCL information corresponding to the reported interference metrics. The interference metrics may include a L 1  SRS RSRP or L 1  CLI RSSI. In some implementations, the report component  124  may determine effects of cross-link interference on the victim UEs. For example, the report component  124  may identify candidate beams for either the aggressor UE or victim UE based on the CLI report. In some implementations, the report component  124  may adjust scheduling based on the CLI reports. 
       FIG.  12    is a conceptual data flow diagram  1200  illustrating the data flow between different means/components in an example UE  1204 , which may be an example of the UE  104  (e.g., victim UE  104   b ) and include the CLI component  140 . 
     As discussed with respect to  FIG.  1   , the CLI component  140  may include the configuration component  142 , the measurement component  144 , and the reporting component  146 . The UE  104  also may include a receiver component  1270  and a transmitter component  1272 . The receiver component  1270  may include, for example, a radio-frequency (RF) receiver for receiving the signals described herein. The transmitter component  1272  may include for example, an RF transmitter for transmitting the signals described herein. In some implementations, the receiver component  1270  and the transmitter component  1272  may be co-located in a transceiver. 
     The receiver component  1270  may receive downlink signals such as the RRC signaling  1030 . The receiver component  1270  may receive cross-link interference such as interference  1042  from the SRS  1040 . The receiver component  1270  may provide the RRC signaling  1030  to the configuration component  142 . The receiver component  1270  may provide the SRS  1040  to the measurement component  144 . 
     The configuration component  142  may receive the RRC signaling  1030  from the receiver component  1270 . The configuration component  142  may extract RRC configured parameters from the RRC signaling  1030 , for example, by decoding the RRC signaling. For example, the configuration component  142  may extract parameters of the CLI report configuration  1032  such as measurement resources  1034  and the QCL information  1036  associated with each measurement resource. In some implementations, the parameters may define a rule for which measurement resources to report. For example, the parameters may define a number of lowest interference metrics, a threshold interference metric, or an indication of whether the UE is to report a best beam. The parameters may define the interference metric to report such as L 1  SRS RSRP and/or L 1  CLI RSSI. The configuration component  142  may provide the CLI report configuration parameters to the reporting component  146 . The configuration component  142  may determine the resources to measure and the beams corresponding to the QCL information. In some implementations, the configuration component  142  may determine the panel to use for each measurement resource. The configuration component  142  may provide the measurement resources, associated beams, and/or panels to the measurement component  144 . 
     The measurement component  144  may receive the measurement resources, QCL information, and/or panels from the configuration component  142 . The measurement component  144  may perform measurements on the measurement resources. The base station  102  may refrain from transmitting on the measurement resources, so any signal received on the measurement resources may be considered cross-link interference. In an aspect, the measurement component  144  may measure a L 1  RSSI to capture the amount of CLI. In some implementations, the measurement component  144  may measure an L 1  RSRP to determine the CLI from a specific aggressor UE  104   a.  The measurement component  144  may provide CLI values to the reporting component  146 . 
     The reporting component  146  may transmit a CLI report based on the CLI report configuration and the measurements. For example, the reporting component  146  may determine a subset of the interference metrics associated with reported measurement resources. For example, the subset may include a configured number of lowest interference metrics. The reporting component  146  may determine the information to include for each measurement resource such as the QCL information associated with the reported measurement resources. The reporting component  146  may determine uplink resources for the CLI report based on the CLI report configuration. The reporting component  146  may transmit the CLI report via the transmitter component  1272 .

For example, the SRS configuration component  1310  may receive the RRC signaling  1020  from the receiver component  1370 . The SRS configuration component  1310  may decode the RRC signaling  1020  to extract parameters of the SRS configuration  1022 . For example, the SRS configuration component  1310  may determine the resource set  1023 , the TCI state  1024 , the panel  1026 , and/or the repetition parameter  1028 . The SRS configuration component  1310  may provide the resource set  1023 , the TCI state  1024 , the panel  1026 , and/or the repetition parameter  1028  to the SRS generator component  1320 . In some implementations, the SRS configuration may include a power control parameter such as an SRS-PowerControlAdjustmentStates parameter that indicates a type of transmission or closed loop index. The SRS configuration component  1310  may provide the power control parameter to the power control component  1330 . 
     The power control parameter  1330  may receive the power control parameter from the SRS configuration component  1310 . The power control component  1330  may determine a transmit power based on the power control parameter. For example, the power control component  1330  may select a transmit power that matches PUSCH or PUCCH transmit power. The power control component  1330  may provide the transmit power to the SRS generator component  1320 . 
     The SRS generator component  1320  may receive the SRS configuration parameters from the SRS configuration component  1310 . The SRS generator component  1320  may transmit an SRS using the TCI state spatial relation parameter, the panel, and a same SRS port on the CLI measurement resources. For example, the SRS generator component  1320  may generate an SRS for the SRS resource set corresponding to the CLI measurement resources. The SRS generator component  1320  may transmit the SRS on the indicated panel using the indicated TCI state spatial relation parameter via the transmitter component  1372 . In some implementations, the SRS generator component  1320  may transmit the SRS with a transmission power using a closed loop index for a PUCCH.
