Background Art

[0003] The following relates to wireless communications, including cross-link interference reporting between user equipment.

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and the like. These systems may be able to support communication with multiple users by sharing 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, advanced LTE (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 techniques 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 communication system may include one or more base stations, each of which supports wireless communication of a communication device, which may be referred to as a user equipment (UE). Summary of the invention

[0057] In some wireless communication systems, a communication device such as a user equipment (UE) or a network entity may support wireless communication through one or more radio access technologies. Examples of radio access technologies may include fourth generation (4G) systems (such as long term evolution (LTE) systems) and fifth generation (5G) systems (which may be referred to as NR systems). In such cases, the communication device may operate in half-duplex mode or full-duplex mode or a combination thereof. In half-duplex mode, the communication device may send or receive communication during a time period such as a transmit time interval (TTI) that may span one or more time resources (e.g., symbols, mini-slots, time slots, etc.). In full-duplex mode, the communication device may simultaneously send and receive communication during the time period. That is, the communication received by the communication device may overlap in the time domain with the communication sent by the communication device.

[0058] In some examples, adjacent communication devices (e.g., UEs, network entities, etc.) may concurrently perform full-duplex communications or half-duplex time division duplex (TDD) such that communications sent by a first communication device such as a first UE may overlap in time with communications received by a second communication device such as a second UE (e.g., an adjacent communication device). In such an example, communications sent by the first UE may interfere with communications received at the second UE. Such interference may be referred to as inter-UE cross-link interference (CLI) or other similar terms. In some examples, CLI may degrade wireless communications between the second UE and the network. Therefore, one or more communication devices may perform interference suppression techniques to reduce CLI, however, conventional techniques may result in increased overhead and may require enhancement.

[0059] Thus, the techniques described herein may support inter-UE CLI interference suppression. For example, a first UE may receive sidelink signaling from one or more other UEs. In some cases, the sidelink signaling may include one or more discovery signals, one or more synchronization signal blocks (SSBs), or one or more sidelink control information (SCI) transmissions. Additionally, the first UE may generate measurement information associated with the inter-UE CLI between the first UE and one or more other UEs based on the sidelink signaling. For example, the measurement information may include a corresponding signal received power for each corresponding UE in one or more other UEs. In addition, the first UE may send an inter-UE CLI interference report to a network entity, the inter-UE CLI interference report including information indicating a first set of one or more UEs from one or more other UEs, wherein each UE in the first set of one or more UEs may be associated with corresponding measurement information that satisfies a threshold. For example, the inter-UE CLI report may include corresponding identifiers for corresponding UEs in a first set of one or more UEs, wherein the first set of one or more UEs is associated with corresponding signal received powers exceeding a threshold. Additionally or alternatively, the first set of one or more UEs may be associated with corresponding signal received powers below a threshold. Thus, the network entity may communicate with the first UE and one or more other UEs based on the inter-UE CLI reporting.

[0060] Various aspects of the disclosure are first described in the context of a wireless communication system. Then, various aspects of the disclosure are described in the context of a full-duplex operation scheme and process flow. Various aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to inter-user equipment cross-link interference reporting.

[0061] Figure 1 An example of a wireless communication system 100 supporting inter-UE CLI reporting according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, a new radio (NR) network, or a network operating according to other systems and radio technologies (including future systems and radio technologies not explicitly mentioned herein).

[0062] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0063] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communication with various types of devices, such as Figure 1 Communicate with other UEs 115 or network entities 105) as shown.

[0064] As described herein, a node (which may be referred to as a node, a network node, a network entity 105, or a wireless node) may include, may be, or may be included in (e.g., a component of) a base station (e.g., any base station described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, an integrated access and backhaul (IAB) node, a distributed unit (DU) 165, a central unit (CU) 160, a remote / radio unit (RU) 170 (which may also be referred to as a remote radio unit (RRU)), and / or another processing entity configured to perform any of the techniques described herein. For example, the network node may be a UE 115. As another example, the network node may be a base station or a network entity 105. As another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE 115, the second network node may be a base station, and the third network node may be a UE 115. In another aspect of this example, the first network node may be a UE 115, the second network node may be a base station, and the third network node may be a base station. In yet other aspects of this example, the first network node, the second network node, and the third network node may be different relative to these examples. Similarly, references to UE 115, base stations, devices, equipment, computing systems, etc. may include disclosures of UE 115, base stations, devices, equipment, computing systems, etc. as network nodes. For example, a disclosure that UE 115 is configured to receive information from a base station also discloses that the first network node is configured to receive information from a second network node. Consistent with the present disclosure, once a specific example is expanded according to the present disclosure (e.g., UE 115 is configured to receive information from a base station also discloses that the first network node is configured to receive information from a second network node), the broader example of the narrower example may be interpreted inversely, but in a broad, open-ended manner. In the above example in which UE 115 is configured to receive information from a base station and the first network node is also disclosed to be configured to receive information from a second network node, the first network node may refer to a first UE 115 configured to receive information, a first base station, a first apparatus, a first device, a first computing system, a first set of one or more components, a first processing entity, etc.; and the second network node may refer to a second UE 115, a second base station, a second apparatus, a second device, a second computing system, a second set of one or more components, a second processing entity, etc.

[0065] As described herein, different terms may be used in various aspects to describe the communication of information (e.g., any information, signal, etc.). The disclosure of one communication term includes the disclosure of other communication terms. For example, a first network node may be described as being configured to send information to a second network node. In this example and consistent with the present disclosure, the disclosure that the first network node is configured to send information to the second network node includes the disclosure that the first network node is configured to provide, transmit, output, communicate, or send information to the second network node. Similarly, in this example and consistent with the present disclosure, the disclosure that the first network node is configured to send information to the second network node includes the disclosure that the second network node is configured to receive, obtain, or decode information provided, transmitted, output, communicated, or sent by the first network node.

[0066] In some examples, the network entities 105 may communicate with the core network 130 or with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, the network entities 105 may communicate with each other directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130) via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, the network entities 105 may communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or fronthaul communication links 168 (e.g., according to a fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0067] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a Home Node B, a Home Evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0068] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0069] The functional split between CU 160, DU 165, and RU 170 is flexible and can support different functions, depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack can be employed between CU 160 and DU 165, such that CU 160 can support one or more layers of a protocol stack and DU 165 can support one or more different layers of a protocol stack. In some examples, CU 160 can host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functions and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functions and signaling, and each may be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 that communicate via those communication links.

[0070] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a collection of independent antennas for relaying communications with the UE 115, or may share the same antenna of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0071] Where the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support inter-UE CLI reporting as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0072] 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 term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. 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, UE 115 may include or may 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 communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0073] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 as shown in .

[0074] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates 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 for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) and TDD component carriers. Communication between the network entity 105 and other devices may refer to communication between a device and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0075] The signal waveform transmitted via the carrier may include 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 using MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be 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), so that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers, beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0076] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources 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).

[0077] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0078] A subframe, a time slot, a mini-time slot, or a symbol may be a minimum scheduling unit of the wireless communication system 100 (e.g., in the time domain) and may be referred to as a TTI. In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the minimum scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0079] Physical channels may be multiplexed according to various techniques in order to communicate using a carrier. For example, physical control channels and physical data channels may be multiplexed using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique to signal via a downlink carrier. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE115 may monitor or search a control region to obtain control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to a plurality of UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0080] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0081] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). UE 115 can be designed to support ultra-reliable, low-latency or critical functions. Ultra-reliable communication 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.

[0082] In some examples, the UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group may be outside of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0083] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0084] 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 a 5G core (5GC), which may include at least one control plane entity for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnecting to an external network (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 of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0085] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). In general, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is about one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using lower frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0086] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations performed using unlicensed bands may be based on carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations performed using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0087] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operation 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 the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communication with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0088] 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 network entity 105, a UE 115) to shape or direct 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 signals communicated via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0089] The wireless communication system 100 may support inter-UE CLI interference suppression. For example, the first UE 115 may receive sidelink signaling from one or more other UEs 115. In some cases, the sidelink signaling may include one or more discovery signals, one or more SSBs, or one or more SCI transmissions. Additionally, the first UE 115 may generate measurement information associated with the inter-UE CLI between the first UE 115 and one or more other UEs 115 based on the sidelink signaling. That is, the sidelink signaling may be associated with one or more measurable resources (e.g., resource blocks (RBs) or resource elements (REs)) (e.g., including one or more measurable resources) so that the first UE 115 can measure these measurable resources to generate measurement information. For example, the first UE 115 may measure the sidelink signal from each corresponding UE 115 in one or more other UEs to generate a corresponding signal received power (e.g., reference signal received power (RSRP)) for each corresponding UE 115 in one or more other UEs 115. In addition, the first UE 115 may send an inter-UE CLI interference report to the network entity 105, the inter-UE CLI interference report including information indicating a first set of one or more UEs 115 from one or more other UEs 115, wherein each UE 115 in the first set of one or more UEs 115 may be associated with corresponding measurement information that meets a threshold. For example, the inter-UE CLI report may include a corresponding identifier for a corresponding UE 115 in the first set of one or more UEs 115, wherein the first set of one or more UEs 115 is associated with a corresponding signal received power that exceeds a threshold. Additionally or alternatively, the first set of one or more UEs 115 may be associated with a corresponding signal received power that is below a threshold. Therefore, the network entity 105 may perform interference suppression based on the inter-UE CLI report, and may communicate with the first UE 115 and the one or more other UEs 115 based on the interference suppression.

[0090] Figure 2A , Figure 2B and Figure 2CEach illustrates an example of a wireless communication system 200 that supports inter-UE CLI reporting according to one or more aspects of the present disclosure. In some examples, the wireless communication system 200 (e.g., wireless communication system 200-a, wireless communication system 200-b, and wireless communication system 200-c) may implement aspects of the wireless communication system 100. For example, the wireless communication systems 200 may each include one or more network entities 105 (e.g., network entity 105-a, network entity 105-b, network entity 105-c, network entity 105-d, network entity 105-e, and network entity 105-f) and one or more UEs 215 (e.g., UE 115-a, UE 115-b, UE 115-c, UE 115-d, UE 115-e, and UE 115-f), which may be as described in reference. Figure 1 Examples of corresponding devices described. Figure 2A , Figure 2B and Figure 2C In the example of Figure 1 Examples of CU 160, DU 165, RU 170, base station 140, IAB node 104, or one or more other network nodes are described. Wireless communication system 200 may include features for improving communication between UE 115 and the network, as well as other benefits.

[0091] exist Figure 2A , Figure 2B and Figure 2C In the example of , UE 115 and network entity 105 may communicate via one or more communication links 210 (e.g., communication link 205-a, communication link 205-b, communication link 205-c, and communication link 205-d) and via one or more communication links 210 (e.g., communication link 210-a, communication link 210-b, communication link 210-c, communication link 210-d, and communication link 210-e). Communication link 205 may be an example of an uplink, and communication link 210 may be an example of a downlink. Additionally or alternatively, communication link 205 and communication link 210 may each be as described in reference Figure 1Examples of communication links 125 described. Each wireless communication system 200 may illustrate communication devices (e.g., one or more UEs 115, one or more network entities 105) operating in full-duplex mode (e.g., performing full-duplex wireless communication) or half-duplex TDD mode (e.g., performing half-duplex TDD wireless communication). That is, full-duplex (or half-duplex TDD) capabilities may exist at one or more network entities 105, one or more UEs 115 (or both). For example, the wireless communication system 200 may support TDD radio bands (e.g., radio spectrum bands configured for TDD communication), FDD radio bands (e.g., radio spectrum bands configured for FDD communication), full-duplex communication at one or more network entities 105 (and / or one or more UEs 115), half-duplex communication at one or more UEs 115, or any combination thereof.

[0092] Each wireless communication system 200 may support multiple types of full-duplex operation. For example, a communication device (e.g., network entity 105, UE 115) operating within the wireless communication system 200 may support in-band full-duplex (IBFD) operation, sub-band FDD (SBFD) operation (e.g., frequency division duplex operation), or both. In some examples of IBFD operation, a communication device may send and receive wireless communications on the same time and frequency resources (e.g., the same time slot and component carrier bandwidth). For example, downlink communications and uplink communications may share time and frequency resources (e.g., IBFD time and frequency resources). In some examples, time and frequency resources may partially overlap or completely overlap. Additionally or alternatively, for SBFD operation, a communication device may send and receive communications on the same time resources and one or more different frequency resources. That is, downlink resources may be separated from uplink resources in the frequency domain.

[0093] exist Figure 2A In an example of , network entity 105-a may support SBFD operation such that downlink communications sent by network entity 105-a (e.g., to UE 115-b) may overlap in time with uplink communications received by network entity 105-a (e.g., from UE 115-a). In some examples, network entity 105-a may configure communications for UE 115-a and UE 115-b according to resource structure 225. Resource structure 225 may include time domain resources (e.g., time slots, symbols) allocated for downlink data 235 (e.g., time domain resources 230-a), time domain resources allocated for uplink data 240 (e.g., time domain resources 230-d), and one or more time domain resources allocated for both downlink data 235 and uplink data 240 (e.g., time domain resources 230-b and time domain resources 230-c).

[0094] In some examples, the time domain resources allocated for both downlink data 235 and uplink data 240 (e.g., time domain resources 230-b and time domain resources 230-c) may be referred to as D+U time slots (or D+U symbols). In some examples, the D+U time slots may include half-duplex symbols (e.g., downlink symbols or uplink symbols) or full-duplex symbols (e.g., both downlink symbols and uplink symbols). For example, time domain resources 230-b and time domain resources 230-c (e.g., D+U time slots) may be examples of time slots in which the radio frequency band is used to send both uplink communications (e.g., uplink transmissions) and downlink communications (e.g., downlink transmissions). In some examples, uplink transmissions and downlink transmissions may occur in overlapping bands (e.g., for IBFD operations) or in adjacent bands (e.g., for SBFD operations).

[0095] For SBFD operation in which uplink transmission and downlink transmission occur in adjacent bands, a half-duplex communication device may transmit in an uplink radio frequency band or receive in a downlink radio frequency band. That is, for a given time domain resource such as time domain resource 230-b (e.g., for a given D+U time slot or a given D+U symbol), a half-duplex device (e.g., UE 115-a, UE 115-b) may transmit uplink data 240 (e.g., perform PUSCH transmission) in an uplink radio frequency band 250, or receive downlink data 235 in a downlink radio frequency band 245. For example, UE 115-a may transmit uplink data 240 in an uplink radio frequency band 250, while UE 115-b may receive downlink data 235 in a downlink radio frequency band 245.

[0096] Additionally or alternatively, for SBFD operations in which uplink and downlink transmissions occur in adjacent bands, a full-duplex device may transmit in an uplink radio band and receive in a downlink radio band. That is, for a given time domain resource such as time domain resource 230-b (e.g., for a given D+U time slot or a given D+U symbol), a full-duplex device may transmit uplink data 240 in an uplink radio band 250 (e.g., perform a PUSCH transmission) and receive downlink data 235 in a downlink radio band 245. Figure 2B In an example, UE 115-c (e.g., a full-duplex device) may send communications in an uplink radio frequency band and receive communications in a downlink radio frequency band (e.g., within the same D+U time slot or the same D+U symbol).

[0097] In some examples, full-duplex communication can provide latency reduction. For example, latency savings can be achieved by receiving downlink signals in uplink time slots. In addition, full-duplex communication can provide spectrum efficiency enhancement (e.g., per cell or per UE), effective resource utilization and coverage extension, and other benefits. However, in some examples, full-duplex communication may cause one or more types of interference, such as inter-cell interference (e.g., from adjacent communication devices), self-interference (e.g., for full-duplex communication devices) and CLI (e.g., inter-cell CLI or intra-cell CLI). For example, a communication device (e.g., one or more network entities 105, one or more UEs 115) may experience self-interference 220 (e.g., self-interference 220-a, self-interference 220-b, self-interference 220-c, and self-interference 220-d) between a pair of beams (such as a beam for sending communication and a beam for receiving communication). In some examples, self-interference may be caused by signal leakage between an antenna panel for sending communication and an antenna panel for receiving communication.

[0098] Additionally or alternatively, neighboring communication devices (e.g., neighboring UE 115, neighboring network entity 105) may concurrently perform full-duplex communication (or half-duplex TDD) such that communications received by a first communication device may overlap in time with communications sent by a second communication device (e.g., neighboring communication device). In such an example, communications sent by the second communication device may interfere with communications received at the first communication device. For example, communications sent by the second communication device may cause CLI at the first communication device. In some examples, CLI (e.g., CLI 215-a, CLI 215-b, CLI 215-c, CLI 215-d, CLI 215-e, or CLI 215-f) may be caused by energy leakage due to timing and frequency misalignment (e.g., misalignment) between neighboring communication devices.

[0099] Additionally or alternatively, CLI may be caused by an automatic gain control (AGC) mismatch (eg, misalignment). Figure 2A As illustrated in the example of , the AGC of UE 115-b may be driven (e.g., controlled) by downlink communications from a serving cell (e.g., network entity 105-a). In such an example, uplink communications sent from UE 115-a may saturate the AGC of UE 115-b, resulting in a misalignment (e.g., loss of orthogonality) of downlink communications received by UE 115-b and uplink communications sent by UE 115-a. In some examples, the misalignment of downlink communications with uplink communications may result in CLI 215-a at UE 115-b.

[0100] In some examples, network entity 105-a may operate in full-duplex mode (e.g., SBFD or IBFD) and UE 115 (e.g., UE 115-a and UE 115-b) may operate in half-duplex mode. For example, network entity 105-a may receive uplink communications from UE 115-a (e.g., via communication link 205-a) while simultaneously sending downlink communications to UE 115-b (e.g., via communication link 210-a). In such an example, full-duplex communication at network entity 105-a may cause self-interference 220-a. Additionally or alternatively, network entity 105-a and network entity 105-b (e.g., adjacent network entities) may perform full-duplex communication concurrently such that a downlink signal sent by network entity 105-b may overlap an uplink signal received by network entity 105-a, thereby causing CLI 215-b.

[0101] Additionally or alternatively, UE 115-a and UE 115-b (e.g., adjacent UEs) may concurrently perform half-duplex TDD communications such that an uplink signal sent by UE 115-b may overlap a downlink signal received by UE 115-a, which may result in CLI 215-a. In some examples, UE 115-a may operate in a cell different from a cell in which UE 115-b may operate. For example, UE 115-a and UE 115-b may operate in adjacent cells. In one example, CLI 215-a may be an example of an inter-cell CLI. Additionally or alternatively, network entity 105-b may concurrently perform full-duplex communications with network entity 105-a. In such an example, downlink communications sent by network entity 105-b may result in inter-cell interference at UE 115-b. For example, downlink communications sent by network entity 105 - b (eg, to another UE (not shown)) may interfere with downlink communications received by UE 115 - b (eg, from network entity 105 - a).

[0102] In some other examples, UE 115-a and UE 115-b may operate in the same cell. In such an example, CLI 215-a may be an example of an intra-cell CLI. For example, network entity 105-a may operate in full-duplex mode (e.g., under SBFD) such that network entity 105-a may configure downlink communications for UE 115-a in frequency domain resources adjacent to frequency domain resources allocated for uplink communications from UE 115-b. For example, network entity 105-a may configure UE 115-b to receive downlink data 235 in time domain resources 230-b and downlink radio band 245 (e.g., from network entity 105-a), and UE 115-a may be configured to send uplink data 240 in time domain resources 230-b in uplink radio band 250 (e.g., adjacent frequency resources). In this example, uplink communications sent by UE 115-a may interfere with downlink communications received at UE 115-b.

[0103] exist Figure 2B In some examples of wireless communication systems 200-b, network entity 105-c and UE 115-c may each operate in a full-duplex mode (e.g., IBDF) such that UE 115-c may receive downlink communications from network entity 105-c via communication link 210-b while simultaneously sending uplink communications to network entity 105-c via communication link 205-c. In such examples, full-duplex communications at network entity 105-c and full-duplex communications at UE 115-c may result in self-interference 220-b and self-interference 220-c, respectively. In some examples of wireless communication systems 200-b, UE 115-c and UE 115-d may each operate in a multiple transmit and receive mode. In such examples, downlink communications and uplink communications performed by network entity 105-c may occur at two different antenna panels located at two transmit and receive points. For example, reception of uplink communications from UE 115-c may occur at an antenna panel at a first transmit and receive point, and transmission of downlink communications to UE 115-c may occur at an antenna panel at a second transmit and receive point. In some other examples, reception of uplink communications and transmission of downlink communications may occur at two co-located antenna panels of a network entity 105-c (e.g., a single base station).

[0104] exist Figure 2CIn an example of a wireless communication system 200-c, UE 115-e may operate in a full-duplex mode (e.g., SBFD) such that UE 115-e may receive downlink communications from network entity 105-f via communication link 210-d while simultaneously sending uplink communications to network entity 105-e via communication link 205-d. In such an example, full-duplex communications at UE 115-e may cause self-interference 220-d. In some examples of wireless communication system 200-c, network entity 105-e and network entity 105-f may be examples of a transmission point and a reception point, and UE 115-e (e.g., and UE 115-f) may operate in a multiple transmission and reception mode. In such an example, uplink communications sent from UE 115-e may cause CLI 215-e (e.g., intra-cell CLI) at UE 115-f.

[0105] Thus, the wireless communication system 200 may support inter-UE CLI interference suppression. For example, UE 115-b may receive sidelink signaling 255 (e.g., including one or more measurable resources) from UE 115-a, and may generate measurement information associated with interference (such as CLI 215-a) between UE 115-a and UE 115-b based on the sidelink signaling 255 (e.g., based on one or more measurable resources). In some cases, the measurement information associated with CLI 215-a between UE 115-a and UE 115-b may include signal received power, such as RSRP. Additionally, UE 115-b may send an interference report 260 (e.g., an inter-UE CLI report) to the network entity 105-a based on the measurement information associated with CLI 215-a between UE 115-a and UE 115-b satisfying a threshold, the interference report including an identifier associated with UE 115-a. In some cases, UE 115-b may send an interference report 260 indicating an identifier associated with UE 115-a based on measurement information associated with CLI 215-a between UE 115-a and UE 115-b exceeding a threshold. That is, interference report 260 may indicate that communications sent by UE 115-a may interfere with communications received by UE 115-b. Alternatively, UE 115-b may send an interference report 260 indicating an identifier associated with UE 115-a based on measurement information associated with CLI 215-a between UE 115-a and UE 115-b failing to exceed a threshold. That is, interference report 260 may indicate that communications sent by UE 115-a may not interfere with communications received by UE 115-b. Therefore, network entity 105-a may perform interference mitigation based on interference report 260, and may communicate with UE 115-a and UE 115-b based on interference mitigation. For example, based on the measurement information associated with the CLI 215-a between the UE 115-a and the UE 115-b failing to exceed a threshold, the network entity 105-a may simultaneously schedule downlink communications on the communication link 210-a and uplink communications on the communication link 205-a based on the interference report 260 indicating an identifier associated with the UE 115-a. Alternatively, based on the measurement information associated with the CLI 215-a between the UE 115-a and the UE 115-b exceeding a threshold, the network entity 105-a may avoid simultaneously scheduling downlink communications on the communication link 210-a and uplink communications on the communication link 205-a based on the interference report 260 indicating an identifier associated with the UE 115-a.

[0106] Figure 3A and Figure 3BEach illustrates an example of a full-duplex operation scheme 300 supporting inter-UE CLI reporting according to one or more aspects of the present disclosure. In some examples, the full-duplex operation scheme 300 (full-duplex operation scheme 300-a and full-duplex operation scheme 300-b) can implement or be implemented by various aspects of the wireless communication system 100. For example, the full-duplex operation scheme 300 can be implemented by the network entity 105 or the UE 115, which can be as described in reference Figure 1 Examples of corresponding devices described. Figure 3A and Figure 3B In some examples, the network entity 105 may be as shown in FIG. Figure 1 Examples of CU 160, DU 165, RU 170, base station 140, IAB node 104, or one or more other network nodes are described. Full-duplex operation scheme 300 may include features for improving communications between UE 115 and network entity 105, among other benefits.

[0107] In some examples, a wireless communication device (e.g., network entity 105 or UE 115) can support full-duplex communication, where the communication device can send and receive communications simultaneously, thereby facilitating latency savings achieved by receiving downlink signals in uplink time slots (or symbols). In some examples, the communication device can support multiple (e.g., two) types of full-duplex operation. For example, the communication device can support SBFD operation, where the communication device can send and receive communications on the same time resources and on different frequency resources. That is, downlink resources can be separated from uplink resources in the frequency domain.

[0108] For example, Figure 3A As illustrated in the example of , the network entity 105 may configure one or more UEs 115 according to the configuration 305-a. In such an example, the network entity 105 may configure a downlink transmission (e.g., transmission of downlink data 310) for UE 115 in a frequency domain resource (e.g., resource 315-a), which may be adjacent to a frequency domain resource (e.g., resource 315-b) configured for uplink transmission (e.g., transmission of uplink data 320) of another UE. In some examples, in order to reduce interference between uplink transmissions (e.g., scheduled for resource 315-a) and downlink transmissions (e.g., scheduled for resource 315-b), the network entity 105 may configure resource 315-a and resource 315-b to be separated by a guard band 316.

[0109] Additionally or alternatively, such as Figure 3BAs illustrated in the example of , the network entity 105 (e.g., the network entity 105 entity) may support IBFD operation such that the network entity 105 entity may send and receive communications on the same time resources and the same frequency resources (e.g., the same time slot and carrier bandwidth). For example, the network entity 105 may configure one or more UEs 115 according to configuration 305-b, configuration 305-c, or both. In such an example, the network entity 105 may configure downlink transmissions (e.g., transmissions of downlink data 310) and uplink transmissions (e.g., transmissions of uplink data 320) such that the downlink transmissions and the uplink transmissions may share the same one or more time and frequency resources (e.g., IBFD time and frequency resources). In some examples, the network entity 105 may configure one or more UEs 115 according to the configuration 305-b such that one or more time and frequency resources (e.g., resources 315-c) allocated for transmission of uplink data 320 may overlap (e.g., completely overlap) with one or more time and frequency resources (e.g., resources 315-d) allocated for transmission of downlink data 310. Additionally or alternatively, the network entity 105 may configure one or more UEs 115 according to the configuration 305-c such that a portion of the one or more time and frequency resources (e.g., resources 315-e) allocated for transmission of uplink data 320 may overlap with a portion of the one or more time and frequency resources (e.g., resources 315-f) allocated for transmission of downlink data 310. That is, resources 315-e may partially overlap with resources 315-f.

[0110] In some examples, while full-duplex communications may provide one or more spectral efficiency enhancements (e.g., per cell or per UE 115), efficient resource utilization, and coverage area extension, concurrent full-duplex communications performed by neighboring communication devices may result in CLI. For example, neighboring communication devices may concurrently perform full-duplex communications such that communications received by a first communication device may overlap in time with communications sent by a second communication device (e.g., a neighboring communication device). In such an example, communications sent by the second communication device may result in CLI at the first communication device.

[0111] In some examples, in order to reduce the impact of CLI (e.g., inter-UE CLI), the network entity 105 may employ one or more interference suppression techniques. For example, the first UE 115 may receive sidelink signaling, such as discovery signaling, SSBS, or SCI, from one or more second UEs 115. Additionally, the first UE 115 may generate corresponding measurement information associated with the inter-UE CLI between the first UE 115 and each second UE 115 based on the corresponding sidelink signaling. For example, the first UE 115 may generate a corresponding signal received power associated with each second UE 115. In addition, the first UE 115 may send an inter-UE CLI report indicating at least a first subset of the one or more second UEs 115 to the network entity 105, wherein the measurement information associated with each second UE 115 in the first subset meets a threshold. In some cases, each second UE 115 of the first subset may be associated with corresponding measurement information exceeding the threshold, which may indicate that the transmission conveyed by each second UE 115 in the first subset may cause CLI at the first UE 115. Alternatively, each second UE 115 in the first subset may be associated with corresponding measurement information that fails to exceed the threshold, which may indicate that the transmission communicated by each second UE 115 in the subset may not result in CLI at the first UE 115. Therefore, the network entity 105 may perform interference mitigation based on the inter-UE CLI report, and may communicate with the first UE 115 and one or more second UEs 115 based on the interference mitigation.

[0112] Figure 4 An example of a wireless communication system 400 supporting inter-UE CLI reporting according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 400 may implement aspects of or be implemented by the wireless communication system 100, the wireless communication system 200, and the full-duplex operation scheme 300. For example, the wireless communication system 400 may each include one or more network entities 105 (e.g., network entity 105-g) and one or more UEs 115 (e.g., UE 115-g and UE 115-h), which may be as described in reference Figure 1 Examples of corresponding devices described. Figure 4 In the example of FIG. 1 , the network entity 105 may be a CU 160, a DU 165, a RU 170, a base station 140, an IAB node 104, or a Figure 1 Examples of one or more other network nodes described.

[0113] In some examples, the wireless communication system 200 may support full-duplex operation such that the network entity 105-g may simultaneously receive uplink signaling 405 (such as uplink signaling 405-a from UE 115-g or uplink signaling 405-b from UE 115-j) and send downlink signaling 410 (e.g., to UE 115-h). In such examples, the uplink signaling 405-a, the uplink signaling 405-b, or both may cause interference (e.g., inter-UE CLI) to the downlink signaling 410 received by UE 115-h.

[0114] Thus, the wireless communication system 400 may support the transmission of inter-UE CLI reports to implement beam identification for inter-UE CLI suppression (e.g., for TDD and FD scenarios). For example, UE 115-h may receive sidelink signaling 415-a from UE 115-g and sidelink signaling 415-b from UE 115-j. In some cases, the sidelink signaling 415 may be one or more discovery messages, one or more SSBs, one or more SCI transmissions, or any combination thereof. In some cases (e.g., Mode 1), the network entity 105-g may send an indication of a configuration associated with the corresponding sidelink signaling 415-a to UE 115-g, UE 115-j, or both. In some other cases (e.g., Mode 2), UE 115-g, UE 115-h, or both may be preconfigured with a configuration associated with the corresponding sidelink signaling 415. Additionally or alternatively, the configuration associated with the sidelink signaling 415-a may be synchronized with the sidelink signaling 415-b or may be time division multiplexed with the sidelink signaling 415-b.

[0115] Additionally, the beam used to send the sidelink signaling 415 can be based on a beam associated with the corresponding uplink signaling 405 (e.g., an access link) or with the downlink signaling 410. For example, a first beam used to send the sidelink signaling 415-a can be based on a second beam used to send the uplink signaling 405-a. Similarly, a third beam used to send the sidelink signaling 415-b can be based on a fourth beam used to send the uplink signaling 405-b. In some examples (e.g., FR1 operation), the beam used to send the sidelink signaling 415 may be the same as the beam used to send the corresponding uplink signaling 405 (e.g., the beam associated with the corresponding uplink signaling 405 may be omnidirectional or quasi-directional). For example, the first beam may be the same as the second beam, and the third beam may be the same as the fourth beam. In some other examples (e.g., FR2), the beam used to send the sidelink signaling 415 can be quasi co-located with the beam used to send the corresponding uplink signaling 405 (e.g., the sidelink signaling 415 is configured with the same quasi co-located root beam or the same or wider beam as the beam used to send the corresponding uplink signaling 405). For example, the first beam can be quasi co-located with the second beam, and the third beam can be quasi co-located with the fourth beam.

[0116] UE 115-h may generate measurement information associated with the inter-UE CLI between UE 115-h and UE 115-g based on sidelink signaling 415-a, and may generate measurement information associated with the inter-UE CLI between UE 115-h and UE 115-j based on sidelink signaling 415-b. That is, UE 115-h may measure one or more measurable resources (e.g., REs or RBs) associated with the respective sidelink signaling 415 to generate respective signal received powers (e.g., RSRP) for each respective UE 115. For example, UE 115-h may generate a first signal received power for UE 115-g based on sidelink signaling 415-a (e.g., measurable resources in sidelink signaling 415-a), and may generate a second signal received power for UE 115-j based on sidelink signaling 415-b (e.g., measurable resources in sidelink signaling 415-b).

[0117] In addition, the UE 115-h may send an interference report 420 (e.g., an inter-UE CLI report) to the network entity 105-g based on the measurement information. That is, the UE 115-h may send an interference report 420 based on the measurement information associated with the UE 115-g, the UE 115-h, or both satisfying a threshold (e.g., a CLI threshold), the interference report including information indicating the UE 115-g, the UE 115-h, or both (e.g., a first set of one or more UEs 115). In some cases, the information indicating the UE 115-g, the UE 115-h, or both may include a respective identifier for each UE 115, such as a first identifier associated with the UE 115-g, a second identifier associated with the UE 115-h, or both.

[0118] In some examples, UE 115-h may determine one or more UEs 115 for which corresponding measurement information (such as corresponding signal received power) exceeds a threshold, and may send an interference report 420 indicating the one or more UEs 115 for which the corresponding measurement information exceeds the threshold. For example, a first signal received power associated with UE 115-g may exceed the threshold, while a second signal received power associated with UE 115-j may be below the threshold. Therefore, UE 115-h may send an interference report 420 including a first identifier associated with UE 115-g based on the first signal received power exceeding the threshold.

[0119] In some examples, UE 115-h may determine one or more UEs 115 whose corresponding measurement information (specifically, corresponding signal received power) is below a threshold, and may send an interference report 420 indicating one or more UEs 115 whose corresponding measurement information is below the threshold. For example, a first signal received power associated with UE 115-g may exceed the threshold, while a second signal received power associated with UE 115-j is below the threshold. Therefore, UE 115-h may send an interference report 420 including a second identifier associated with UE 115-g based on the second signal received power being below the threshold.

[0120] In some cases, UE 115-h may indicate the number of UEs 115 in interference report 420. That is, UE 115-g may receive information indicating the number of UEs 115 that UE 115-g is to indicate in interference report 420. For example, UE 115-g may receive information indicating that UE 115-g is reporting a subset of UEs 115 from the set of UEs 115 that are associated with the five largest signal received powers (e.g., that exceed a threshold) from the signal received powers associated with the set of UEs 115. In another example, UE 115-g may receive information indicating that UE 115-g is reporting a subset of UEs 115 from the set of UEs 115 that are associated with the five smallest signal received powers (e.g., that are below a threshold) from the signal received powers associated with the set of UEs 115.

[0121] Additionally or alternatively, the interference report 420 may include information indicating a corresponding transmit beam associated with corresponding measurement information corresponding to each of the indicated UEs 115 (e.g., each UE 115 in a first set of one or more UEs 115). For example, the interference report 420 may indicate a first beam associated with UE 115-h (e.g., based on indicating UE 115-h). In some examples, UE 115-g may indicate the first beam to UE 115-h via sidelink signaling 415-a. That is, the sidelink signaling 415-a may indicate a beam identifier associated with the first beam (e.g., via a transmit configuration indicator (TCI) field). Alternatively, UE 115-h may determine (e.g., identify) the first beam based on a reference signal (e.g., a QCL source reference signal in a Uu link).

[0122] Additionally or alternatively, the interference report 420 may include information indicating a respective receive beam associated with respective measurement information corresponding to each of the indicated UEs 115 (e.g., each UE 115 in the first set of one or more UEs 115). For example, the UE 115-h may receive the sidelink signaling 415-a using the fifth beam, and the interference report 420 may indicate (e.g., based on indicating the UE 115-h) the fifth beam associated with receiving the sidelink signaling 415-a from the UE 115-h. In some cases, the UE 115-h may determine (e.g., identify) the fifth beam based on a reference signal (e.g., a QCL source reference signal in a Uu link).

[0123] Additionally or alternatively, the interference report 420 may include information indicating respective time and frequency resources associated with respective measurement information corresponding to each of the indicated UEs 115 (e.g., each UE 115 in the first set of one or more UEs 115). In some examples, the time and frequency resources may be associated with reception (e.g., detection) of respective sidelink signaling 415 (e.g., such that the network entity 105-g may be aware of one or more transmit parameters, such as transmit power, of the respective UE 115 that sent the respective sidelink signaling 415).

[0124] Additionally or alternatively, the interference report 420 may include information indicating a respective path loss between each of the indicated UEs 115 (eg, each UE 115 in a first set of one or more UEs 115) and the UE 115-h.

[0125] Additionally or alternatively, the interference report 420 may include information indicating location information corresponding to the indicated UE 115 (e.g., each UE 115 in the first set of one or more UEs 115). In some cases, the location information may be associated with a location area of ​​the corresponding UE 115 (e.g., a location area may be defined as a rectangular area surrounding the surface of the earth, such as a rectangular area of ​​10 meters by 10 meters). For example, UE 115-g, UE 115-j, or both may send the corresponding location information to UE 115-h (e.g., via a corresponding sidelink signal 415). In some cases, the interference report may exclude information indicating that the UE 115 is greater than a threshold distance from UE 115-h. For example, UE 115-h may be configured to report UEs 115, such as UE 115-g, that are associated with a signal received power that exceeds a threshold (e.g., a CLI threshold). However, the location of UE 115-h may be at a distance from UE 115-h that is greater than a threshold distance, such that UE 115-h may avoid indicating UE 115-g in interference report 420. Conversely, UE 115-h may report UEs 115 that are within a threshold distance from UE 115-h (e.g., associated with a location area that is within the threshold distance from UE 115-h).

[0126] In some examples, the interference report 420 may indicate whether each indicated UE 115 (e.g., each UE 115 in a first set of one or more UEs 115) is within a coverage area of ​​a network associated with the network entity 105-g. For example, the interference report 420 may include information indicating a network cell identifier associated with each indicated UE 115 within the coverage area of ​​the network. In some examples, each sidelink UE 115 (such as UE 115-g and UE 115-j) may send an indication of the respective network cell identifier in respective sidelink signaling 415. In such cases, the network entity 105-g may coordinate with one or more additional network entities 105 based on the interference report 420. For example, the interference report 420 may indicate that the transmission by the UE 115-g resulted in an inter-UE CLI at the UE 115-h, where the UE 115-g is within the coverage area of ​​the network associated with the network entity 105-g and is communicating with another network entity 105. Thus, the network entity 105 - g may perform interference mitigation by coordinating with other network entities 105 .

[0127] Alternatively, the interference report 420 may include information indicating an invalid (e.g., reserved) cell identifier or no cell identifier associated with each indicated UE 115 outside the coverage area of ​​the network. In such a case, the network entity 105-g may perform interference mitigation by communicating with each indicated UE 115 outside the coverage area of ​​the network via a relay communication link. Additionally or alternatively, the network entity 105-g may send signaling to the UE 115-h instructing the UE 115-h to avoid reporting UEs 115 outside the coverage area of ​​the network, regardless of the associated measurement information (e.g., the network entity 105-g may not be able to perform interference mitigation by communicating with each UE 115 outside the coverage area of ​​the network).

[0128] Although some examples herein are described in the context of CLI between a first UE 115 (e.g., UE 115-h) and one or more other UEs 115 (e.g., UE 115-g and UE 115-j), this should not be viewed as limiting the present disclosure. Rather, the techniques described herein may be implemented by any one or more types of network nodes. For example, the CLI may be related signaling or interference between a first type of network node (e.g., UE 115 is an example of the first type of network node), and a CLI interference report may be sent by the first type of network node to a second type of network node (e.g., network entity 105 is an example of the second type of network node).

[0129] Figure 5An example of a process flow 500 for supporting inter-UE CLI reporting according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 500 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the full-duplex operation scheme 300, and the wireless communication system 400. For example, the process flow 500 may each include one or more network entities 105 (e.g., network entity 105-h) and one or more UEs 115 (e.g., UE 115-m and UE 115-n), which may be as described in reference Figure 1 Examples of corresponding devices described. Figure 5 In the example of FIG. 1 , the network entity 105 may be a CU 160, a DU 165, a RU 170, a base station 140, an IAB node 104, or a Figure 1 Examples of one or more other network nodes described. In some examples, UE 115-m may send an inter-UE CLI report to network entity 105-h.

[0130] At 505, the network entity 105-h may establish respective connections with the UE 115-m and the UE 115-n.

[0131] At 510, UE 115-n may receive sidelink signaling from one or more other UEs 115 (including at least UE 115-m). The sidelink signaling may include one or more discovery signals, one or more SSBs, or one or more SCIs.

[0132] In some examples, sidelink signaling from one or more other UEs 115 may be associated with one or more beams that are also associated with uplink or downlink communications between the network entity 105-h and the one or more other UEs 115. For example, sidelink signaling from UE 115-m may be associated with one or more beams that are also associated with uplink communications between the network entity 105-h and UE 115-m. Additionally or alternatively, sidelink signaling from one or more other UEs 115 may be associated with one or more first beams that are quasi-co-located with one or more second beams associated with uplink or downlink communications between the network entity 105-h and the one or more other UEs 115.

[0133] At 515, UE 115-n may generate measurement information associated with an inter-UE CLI between UE 115-n and one or more other UEs 115 based on the sidelink signaling. For example, UE 115-n may generate first measurement information associated with an inter-UE CLI between UE 115-n and UE 115-m. In some examples, the measurement information may include a respective signal received power for each respective UE 115 in the one or more other UEs 115. For example, the first measurement information may include a first signal received power associated with UE 115-m.

[0134] In some examples, at 520, UE 115-m may determine one or more UEs 115 whose corresponding signal reception power exceeds a threshold from one or more other UEs 115. Alternatively, UE 115-m may determine one or more UEs 115 whose corresponding signal reception power is below a threshold from one or more other UEs 115.

[0135] In some examples, UE 115-n may receive information indicating a number of UEs 115 that UE 115-n is to indicate in an inter-UE CLI report via information indicating a first set of one or more UEs 115. Accordingly, UE 115-m may determine a subset of one or more UEs 115 that includes the number of UEs 115 from the one or more other UEs 115. In some examples, the subset of one or more UEs 115 is associated with corresponding measurement information that is: greater than a corresponding measurement information value for each UE 115 of the one or more other UEs 115 that is not in the subset, wherein a threshold value includes a lowest corresponding measurement information value associated with the subset of one or more UEs 115; or less than a corresponding measurement information value for each UE 115 of the one or more other UEs 115 that is not in the subset, wherein the threshold value includes a highest corresponding measurement information value associated with the subset of one or more UEs 115.

[0136] At 525, UE 115-n may send an inter-UE CLI report to network entity 105-h, the inter-UE CLI report including information indicating a first set of one or more UEs 115 from one or more other UEs 115, wherein each UE 115 in the first set of one or more UEs 115 is associated with respective measurement information in the measurement information that satisfies (e.g., exceeds or falls below) a threshold. For example, the inter-UE CLI report may include information indicating at least UE 115-m based on the first measurement information satisfying the threshold. In some examples, the information indicating the first set of one or more UEs includes a respective identifier for each respective UE in the first set of one or more UEs.

[0137] In some examples, the inter-UE CLI report may include information indicating a respective transmit beam associated with respective measurement information corresponding to each respective UE 115 in the first set of one or more UEs 115. Additionally or alternatively, the inter-UE CLI report may include information indicating a respective receive beam associated with respective measurement information corresponding to each respective UE 115 in the first set of one or more UEs 115. Additionally or alternatively, the inter-UE CLI report may include information indicating respective time and frequency resources associated with respective measurement information corresponding to each respective UE 115 in the first set of one or more UEs 115. Additionally or alternatively, the inter-UE CLI report may include information indicating a respective path loss between each respective UE 115 in the first set of one or more UEs 115 and UE 115-n.

[0138] In some examples, the inter-UE CLI report may include first information indicating whether each respective UE 115 in a first set of one or more UEs 115 is within a coverage area of ​​a network including the network entity 105-h. For example, the first information may indicate a network cell identifier associated with the respective UE 115 for each respective UE 115 in the first set of one or more UEs 115 that is within the coverage area of ​​the network. Additionally or alternatively, the first information indicates a respective invalid cell identifier or no cell identifier for each respective UE 115 in the first set of one or more UEs 115 that is outside the coverage area of ​​the network. In some examples, the inter-UE CLI report may exclude information indicating a second set of one or more UEs 115 based on each respective UE 115 in a second set of one or more UEs 115 from one or more other UEs 115 being outside the coverage area of ​​the network including the network entity 105-h.

[0139] In some examples, a particular UE 115 from one or more other UEs 115 may be associated with corresponding measurement information that satisfies a threshold, and the inter-UE CLI report may exclude information indicating the particular UE 115 based on the particular UE 115 being outside of a coverage area of ​​a network including the network entity 105-h.

[0140] In some examples, the inter-UE CLI report may include information indicating respective location information corresponding to each respective UE 115 in a first set of one or more UEs 115. That is, UE 115-n may receive second information indicating respective location information corresponding to each UE in one or more other UEs 115. In some examples, the inter-UE CLI report may exclude information indicating the second set of one or more UEs 115 based on each respective UE 115 in a second set of one or more UEs 115 from the one or more other UEs 115 being greater than a threshold distance from UE 115 115-n. Alternatively, each respective UE 115 in the first set of one or more UEs 115 may be within a threshold distance of UE 115-n, and the inter-UE CLI report may include information indicating the first set of one or more UEs 115 based on each respective UE 115 in the first set of one or more UEs 115 being within the threshold distance.

[0141] For example, UE 115-n may receive second information indicating location information corresponding to UE 115-m.

[0142] In some examples, at 530, the network entity 105-h may perform interference mitigation based on the inter-UE CLI and may communicate with the UE 115-m and the UE 115-n based on the interference mitigation.
