Technical Field

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. 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 network entities, each of which supports wireless communication of communication devices, which may be referred to as user equipment (UE). In some wireless communication systems, a communication device may send or receive communication concurrently or overlappingly in time, which may cause one or more communication devices to experience cross-link interference.

[0050] Some wireless communication systems may include a communication device (such as a user equipment (UE) or a network entity) that supports wireless communication via one or more radio access technologies (RATs). Examples of RATs 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). A communication device may operate in half-duplex mode or full-duplex mode or a combination thereof. For example, in half-duplex mode, a communication device may send or receive communication during a certain time period (such as a transmit time interval (TTI) that may span one or more time resources (e.g., symbols, mini-slots, time slots)). In full-duplex mode, a communication device may send and receive communication simultaneously or concurrently. That is, a communication received by a communication device may overlap in the time domain with a communication sent by the communication device. For example, a symbol occupied by a received signal or allocated for a received signal may overlap with a symbol occupied by a transmitted signal or allocated for a transmitted signal.
[0051] In some examples, adjacent communication devices (e.g., UE or other wireless devices) may concurrently perform full-duplex communication or half-duplex time division duplex (TDD) so that downlink communication received by a first communication device may overlap at least partially in time with uplink communication sent by a second communication device (e.g., an adjacent communication device). In such examples, uplink communication sent by a second communication device may interfere with downlink communication received at a first communication device. Such interference may be referred to as cross-link interference. In some examples, cross-link interference may degrade wireless communication between a first communication device and a network. In order to mitigate or reduce the impact of cross-link interference, the network may configure the first communication device to measure and report cross-link interference.
[0052] For example, the network may configure the communication device to have resources for performing cross-link interference measurements on uplink signals sent by adjacent communication devices. In some examples, the communication device may perform cross-link interference measurements based on a transmit configuration indicator (TCI) state associated with a data signal (e.g., the data signal last received in time) or a control resource set (e.g., the control resource set last monitored in time). However, in some examples, the communication device may be configured to operate in a multi-transmit and receive point (TRP) mode so that the communication device can simultaneously receive downlink signals from multiple TRPs. In such examples, the communication device may receive downlink signals from multiple TRPs via multiple receive beams (e.g., separate beamforming directions that can each be associated with a corresponding TCI state). In some examples, the cross-link interference experienced by the communication device may be different for each of the multiple receive beams. In this example, the communication device may not be able to determine which receive beam (e.g., which TCI state) to use to perform cross-link interference measurements.
[0053] Various aspects of the present disclosure relate as a whole to techniques for cross-link interference measurement and reporting in a multi-TRP system, and more specifically to techniques for configuring a communication device to have one or more TCI states for performing cross-link interference measurement and reporting. For example, a network may send control signaling to configure a communication device to measure and report cross-link interference measurements. In some examples, the control signaling may indicate one or more TCI states that a communication device may use to perform cross-link interference measurements. For example, a communication device may perform cross-link interference measurements using one or more receive beams, each of which may be associated with a corresponding TCI state indicated to the communication device via control signaling. In some other examples, a network may configure a communication device to perform cross-link interference measurements using one or more TCI states associated with a relatively last monitored control resource set or a relatively last received data signal (e.g., a relatively last received physical downlink shared channel (PDSCH) transmission). In some examples, a relatively last monitored control resource set or a relatively last received data signal may be associated with two TCI states. In this example, the communications device may determine to use one or both of the TCI states to perform cross-link interference measurements based on a corresponding identifier of each TCI state.
[0054] In some examples, the communication device may be configured to perform cross-link interference measurements at multiple occasions. In this example, if the communication device is configured to perform cross-link interference measurements according to two (e.g., separate) TCI states, the communication device may perform cross-link interference measurements according to one or two TCI states at each of the multiple occasions. In some examples, the network may configure the communication device to report one or more metrics (e.g., cross-link interference metrics) associated with the cross-link interference measurement. For example, the network may configure the communication device to report multiple cross-link interference metrics, each of which corresponds to a cross-link interference measurement performed according to a single TCI state. Additionally or alternatively, the network may configure the UE to report an average cross-link interference metric corresponding to the cross-link interference measurement performed according to multiple TCI states.
[0055] Certain aspects of the subject matter described herein can be implemented to achieve one or more of the following potential advantages. The techniques employed by the described communication device can provide benefits and enhancements to the operation of the communication device, including enabling the communication device to be configured with one or more TCI states for performing cross-link interference measurements. In addition, the techniques for cross-link interference measurement and reporting in a multi-TRP system as described herein can support higher data rates, spectrum efficiency enhancements, and efficient resource utilization, thereby improving throughput and reliability. Such techniques can result in improved network operation and network efficiency, as well as other benefits.
[0056] Aspects of the present disclosure are first described in the context of wireless communication systems. Aspects of the present disclosure are also described in the context of measurement schemes and process flows. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow charts related to cross-link interference measurement and reporting in a multi-TRP system.

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).
[0058] 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 entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or other names such as network equipment. In some examples, the network entity 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., a radio frequency (RF) access link). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area), and the UE 115 and the network entity 105 may establish one or more communication links 125 over the coverage area. The coverage area 110 may be an example of a geographic area in which the network entity 105 and the UE 115 may support signal communications according to one or more RATs.
[0059] 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 can communicate with various types of devices, such as Figure 1 Communicate with other UEs 115 or network entities 105) as shown.
[0060] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.
[0061] 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 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 .
[0062] 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 giga-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, standalone) 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).
[0063] 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 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)).
[0064] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities 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, and RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality 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) functionality and signaling, and may each 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 the other of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) functions 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 communicating over those communication links.
[0065] 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 the 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 host entities or IAB hosts. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a host network entity 105 (e.g., a host base station 140). One or more host network entities 105 (e.g., IAB hosts) 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 host. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas 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.
[0066] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support cross-link interference measurement and reporting in a multi-TRP system 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).
[0067] 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 "device" may also be referred to as other examples such as a unit, a station, a terminal, or a client. 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 other examples such 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, which may be implemented in various objects such as appliances or vehicles, meters, and other examples.
[0068] 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, and other examples, such as Figure 1 shown.
[0069] UE 115 and network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) on one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for 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 UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured to have 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 "sending," "receiving," or "communicating," when referring to the network entity 105, may refer to any portion of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).
[0070] The signal waveform sent on the carrier may be composed of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM technology, 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 amount 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 the more resource elements a device receives and the higher the order of the modulation scheme, the higher the data rate for the device may be. 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 of communications with UE 115.
[0071] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple 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 maximum supported subcarrier interval, and N f The maximum 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).
[0072] 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 multiple 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 multiple symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, the time slot may also be divided into multiple mini-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.
[0073] 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 bursts of shortened TTIs (sTTIs)).
[0074] Physical channels may be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels may be multiplexed on a downlink carrier using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set) for a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., control resource sets) may be configured for a group of UEs 115. For example, one or more of these UEs 115 may monitor or search a control region for 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 .
[0075] 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 RATs.
[0076] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 may be designed to support ultra-reliable or 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 applications or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency are used interchangeably herein.
[0077] In some examples, a UE 115 may be able to communicate 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 or 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, the network entity 105 may facilitate scheduling of resources for D2D communication. In some other examples, D2D communications may occur between UEs 115 without involving network entity 105 .
[0078] 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 for 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 delivered via a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 for 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.
[0079] 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 kilohertz (GHz). Typically, 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 approximately 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 service to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using smaller frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.
[0080] The wireless communication system 100 may utilize both licensed RF spectrum bands and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed RF spectrum band, devices such as the network entity 105 and the UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating in a licensed band. Operations in an unlicensed spectrum may include other examples such as downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions.
[0081] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that 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 that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may have an antenna array having a set of rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.
[0082] The network entity 105 or UE 115 may use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such technology may be referred to as spatial multiplexing. Multiple signals may be, for example, sent by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are sent to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are sent to multiple devices.
[0083] 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 steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed 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 the antenna elements may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other orientation).
[0084] The network entity 105 or UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the network entity 105 along different directions. For example, the network entity 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105), or by a receiving device (such as UE 115)) beam directions for later transmission or reception by the network entity 105.
[0085] Some signals, such as data signals associated with a particular receiving device, may be sent by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device (such as receiving network entity 105 or receiving UE 115)). In some examples, a beam direction associated with transmission along a single beam direction may be determined based on signals sent along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network entity 105 along different directions, and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.
[0086] In some examples, transmission by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more subbands. Network entity 105 may send a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or non-precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).
[0087] A receiving device (e.g., UE 115) may perform receiving operations according to multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple receiving directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).
[0088] In some examples, the wireless communication system 100 may support a technology for configuring a communication device (such as UE 115) to have one or more TCI states for performing cross-link interference measurements and reports. For example, UE 115 may receive a message from the network indicating a configuration for measuring cross-link interference associated with UE 115. The configuration may indicate one or more TCI states for use by UE 115 to perform one or more cross-link interference measurements. In some examples, UE 115 may perform one or more cross-link interference measurements according to the configuration. For example, UE 115 may perform one or more cross-link interference measurements on a cross-link interference resource set using one or more TCI states. In some examples, UE 115 may send a cross-link interference report indicating one or more cross-link interference metrics corresponding to one or more cross-link interference measurements. In some examples, by performing cross-link interference measurements according to one or more TCI states, UE 115 may increase the reliability of wireless communication between UE 115 and the network and other benefits.
[0089] Figure 2 An example of a wireless communication system 200 that supports cross-link interference measurement and reporting in a multi-TRP system according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement one or more aspects of the wireless communication system 100, or be implemented by it. For example, the wireless communication system 200 may include one or more UEs 215 (e.g., UE 215-a and UE 215-b), which may each be a reference Figure 1 An example of a UE 115 is described.
[0090] The wireless communication system 200 may also include one or more network entities 205 (eg, network entity 205-a and network entity 205-b), each of which may be as described in reference Figure 1 Examples of one or more network entities 105 (e.g., CU, DU, RU, base station, IAB node, TRP, or one or more other network nodes) are described. The network entity 205 and the UE 215 can communicate within one or more coverage areas 210 (e.g., coverage area 210-a, coverage area 210-b), which can each be as described in reference Figure 1 An example of a coverage area 110 is described. Figure 2In an example of , network entity 205-a can serve a cell providing coverage area 210-a, and network entity 205-b can serve a cell providing coverage area 210-b. In some examples, the cell providing coverage area 210-a can be an example of a macro cell, on which downlink traffic may be relatively heavy (may exceed a threshold traffic volume per unit time). Additionally or alternatively, the cell providing coverage area 210-b can be an example of a small cell, on which uplink traffic may be relatively heavy. The wireless communication system 200 may include features for improving communication between UE 215 and the network, as well as other benefits.
[0091] exist Figure 2 In the example of , UE 215 and network entity 205 may communicate via one or more communication links. For example, UE 215-a may send communications (e.g., uplink communications) to network entity 205-a via communication link 230-a, and UE 215-b may send communications to network entity 205-b via communication link 230-b. Figure 2 In the example of , communication link 230 can be an example of an uplink communication link. Additionally or alternatively, UE 215-a can receive communications (e.g., downlink communications) from network entity 205-a via communication link 220, which can be an example of a downlink communication link. Communication link 230 and communication link 220 can each be as described in reference Figure 1 An example of a communication link 125 is described.
[0092] In some examples, UE 215-a and UE 215-b may perform full-duplex communications or half-duplex TDD concurrently such that downlink communications received by UE 215-a (e.g., via communication link 220) may overlap at least partially in time with uplink communications sent by UE 215-b (e.g., via communication link 230-b). In this example, UE 215-a and UE 215-b may be spatially positioned such that concurrent uplink communications sent by UE 215-b may cause cross-link interference 240 at UE 215-a. In some examples, cross-link interference 240 may degrade downlink communications received by UE 215-a. Therefore, in order to reduce (e.g., mitigate or prevent) cross-link interference, the network (e.g., network entity 205-a) may configure UE 215-a to measure and report cross-link interference experienced at UE 215-a. In some examples, the network can configure UE 215-a to measure and report cross-link interference via higher layer (e.g., L3, RRC layer) signaling. For example, the network can send a message (e.g., an RRC message) that configures UE 215-a to have resources (e.g., time and frequency resources) for performing cross-link interference measurements on uplink signals (e.g., sounding reference signals (SRS)) sent by UE 215-b. In some examples, UE 215-a can perform cross-link interference measurements within configured (e.g., scheduled) resources.
[0093] In some examples, cross-link interference measurements may include frequency domain measurements (e.g., frequency domain reference signal received power (RSRP) measurements) or time domain measurements (e.g., time domain received signal strength indicator (RSSI) measurements). For example, the network may configure resources for RSSI measurements (such as cross-link interference RSSI (CLI-RSSI) measurements) (e.g., for measuring SRS sent by UE215-b). In some examples, the network may configure such resources via an information element (IE) (such as rssiResourceConfigCLIIE). In some other examples, the network may configure resources for RSRP measurements (e.g., SRS-RSRP measurements) (e.g., for measuring SRS sent by UE 215-b). In some examples, the network may configure such resources via an IE (such as srsResourceConfigCLI IE). It should be understood that the names of the IEs described herein may change based on the specific implementation of one or more devices (e.g., UE 215, network entity 205, or both), and the examples described herein should not be considered to be limited to the scope of the present disclosure.
[0094] In some examples, UE 215-a may be able to perform cross-link interference measurements (e.g., CLI-RSSI measurements or SRS-RSRP measurements) within an active BWP (e.g., an active downlink BWP). In some examples (e.g., if UE 215-a is configured to operate in TDD mode), the network may configure UE 215-a to have one or more rules for performing cross-link interference measurements (e.g., CLI-RSSI measurements or SRS-RSRP measurements) within an active BWP. For example, UE 215-b may refrain from performing SRS-RSRP measurements on resources (e.g., SRS resources) that may have a subcarrier spacing that is different from the subcarrier spacing configured for an active BWP that restricts SRS resources. Additionally or alternatively, UE 215-a may refrain from performing SRS-RSRP measurements on SRS resources that may not be restricted (e.g., fully restricted) within a downlink active BWP. Additionally or alternatively, UE 215-a may refrain from performing SRS-RSRP measurements on SRS resources that may exceed the number of resources (REs, RBs, etc.), e.g., 32. For example, the network may configure UE 215-a to refrain from receiving (e.g., the network may refrain from scheduling) more than a certain number (e.g., 8) of SRS resources for performing SRS-RSRP measurements during a certain time duration (e.g., time slot).
[0095] In some examples, UE 215-a may perform cross-link interference measurements while operating in one or more modes. For example, UE 215-a may perform cross-link interference measurements while operating in a connected mode, such as an RRC connected intra-frequency (or inter-frequency) mode that may be indicated via an RRC_CONNECTED IE. Additionally or alternatively, UE 215-a may perform cross-link interference measurements while operating in an idle mode, such as an RRC idle intra-frequency (or inter-frequency) mode that may be indicated via an RRC_IDLE IE. Additionally or alternatively, UE 215-a may perform cross-link interference measurements while operating in an inactive mode, such as an RRC inactive intra-frequency (or inter-frequency) mode that may be indicated via an RRC_INACTIVE IE. Additionally or alternatively, in some examples, the network may configure UE 215-a to suppress cross-link interference measurements on carriers (e.g., NR carriers) that may occur on the same radio frequency band as a serving carrier (e.g., a carrier of a serving cell (such as an E-UTRA serving cell)). Additionally or alternatively, the network may configure UE 215-a to perform cross-link interference measurements when UE 215-a supports simultaneous reception and transmission for inter-band carrier aggregation or inter-band dual connectivity (e.g., E-UTRA-NR dual connectivity, NR-E-UTRA dual connectivity, NR dual connectivity).
[0096] In some examples, UE 215-a may use a quasi-co-site relationship associated with a TCI state to determine (e.g., identify, select) a receive beam (e.g., beamforming direction) for performing cross-link interference measurements. For example, UE 215-a may use a receive beam to perform cross-link interference based on a quasi-co-site relationship (e.g., a quasi-co-site relationship associated with spatial parameters of the receive beam, a D-type quasi-co-site relationship) between configured resources and the TCI state (e.g., beam) used by UE 215-a for receiving downlink data signals (e.g., PDSCH transmissions) or the TCI state (e.g., beam) used by UE 215-a for monitoring control resource sets. In some examples, UE 215-a may perform cross-link interference measurements using a TCI state relative to the last received PDSCH transmission or relative to the last monitored control resource set.
[0097] Additionally or alternatively, UE 215-a may perform cross-link interference measurements based on an offset relative to a downlink reference timing in a serving cell (e.g., supported by network entity 205-a). That is, as part of performing cross-link interference measurements (e.g., RSRP measurements or RSSI measurements), UE 215-a may apply an offset (e.g., a constant offset) derived by UE 215-a (or indicated by the network to UE 215-a). In some examples, the value of the offset may be at least equal to a value determined according to the following equation 1:
[0098] T c *N TA_offset (1)
[0099] Where T c N may represent a timing unit (e.g., a basic timing unit) that may depend on a subcarrier spacing configured for UE 215-a (e.g., an uplink carrier subcarrier spacing or a downlink subcarrier spacing configured for UE 215-a). Additionally or alternatively, N TA_offset N may represent a timing offset (e.g., a timing advance offset) of a serving cell (e.g., supported by network entity 205-a). In some examples, the network may indicate N to UE 215-a via an IE (such as nTimingAdvanceOffset IE). TA_offset For example, the network may configure a UE (e.g., UE 215-a or UE 215-b) with a timing advance value (e.g., N TA_offset ) so that uplink transmissions received by the network can be synchronized.
[0100] In some examples, UE 215-a may be configured to operate in a multi-TRP mode such that UE 215 can receive downlink signals from multiple TRPs simultaneously. For example, UE 215-a can simultaneously receive downlink communications from network entity 205-a and another network entity (not shown). In this example, UE 215-a may receive downlink communications from multiple TRPs via multiple receive beams (e.g., separate receive beams), which may each be associated with a corresponding TCI state. Therefore, the cross-link interference experienced by UE 215-a (e.g., due to concurrent uplink communications sent by UE 215-b) may be different for each of the multiple receive beams.
[0101] In some examples, techniques for cross-link interference measurement and reporting in a multi-TRP system as described herein can provide one or more enhancements to communications between UE 215-a and a network by enabling UE 215-a to perform cross-link interference measurements using one or more TCI states. For example, UE 215-a can receive a message indicating a cross-link interference configuration 225 from network entity 205-a (e.g., via communication link 220). Cross-link interference configuration 225 can be an example of a configuration for measuring cross-link interference associated with UE 215-a. In some examples, cross-link interference configuration 225 can indicate one or more TCI states for UE 215-a to use to perform one or more cross-link interference measurements.
[0102] In some examples, UE 215-a may perform one or more cross-link interference measurements based on cross-link interference configuration 225. For example, UE 215-a may perform one or more cross-link interference measurements on a cross-link interference resource set using one or more TCI states indicated by cross-link interference configuration 225. In some examples, UE 215 may send a cross-link interference report 235 indicating one or more cross-link interference metrics corresponding to the one or more cross-link interference measurements. In some examples, by sending cross-link interference report 235, UE 215-a may enhance cross-link interference techniques performed by network entity 205-a, thereby increasing communication reliability between UE 215-a and network entity 205-a, as well as other benefits.
[0103] Figure 3A and Figure 3B Each illustrates an example of a wireless communication system 300 that supports cross-link interference measurement and reporting in a multi-TRP system according to one or more aspects of the present disclosure. In some examples, the wireless communication system 300 (e.g., wireless communication system 300-a and wireless communication system 300-b) can implement aspects of the wireless communication system 100 and the wireless communication system 200. For example, these wireless communication systems 300 can each include one or more network entities 305 (e.g., network entity 305-a, network entity 305-b, network entity 305-c, network entity 305-d, and network entity 305-e) and one or more UEs 315 (e.g., UE 315-a, UE 315-b, UE 315-c, and UE 315-d), which can be as described in reference Figure 1 and Figure 2 Examples of corresponding devices described. Figure 3A and Figure 3B In the example of FIG. 1 , the network entities 305 may each be as shown in FIG. Figure 1Examples of a CU, DU, RU, base station, IAB node, TRP, or one or more other network nodes are described.
[0104] exist Figure 3A In the example of , UE 315-b and network entity 305-c can communicate within coverage area 310-b. For example, UE 315-b can send communications to network entity 305-c via communication link 320-a. Additionally or alternatively, UE 315-a, network entity 305-a, and network entity 305-b can communicate within coverage area 310-a. For example, UE 315-a can receive communications from network entity 305-a via communication link 330-a, and receive communications from network entity 305-b via communication link 330-b. Figure 3B In the example of , UE 315-c, UE 315-d, network entity 305-d, and network entity 305-e can communicate within coverage area 310-c. For example, UE 315-d can send communications to network entity 305-e via communication link 320-b. Additionally or alternatively, UE 315-c can receive communications from network entity 305-d via communication link 330-c, and receive communications from network entity 305-e via communication link 330-d. In some examples, communication link 320 can each be an example of an uplink, and communication link 330 can each be an example of a downlink. Additionally or alternatively, communication link 320 and communication link 330 can each be as described in reference Figure 1 Additionally or alternatively, the coverage areas 310 may each be as described with reference to Figure 1 An example of a depicted coverage area 110. Wireless communication systems 300 may each include features for improving communications between UE 315 and the network, among other benefits.
[0105] Each wireless communication system 300 may illustrate a communication device (e.g., one or more UEs 315 or one or more network entities 305) operating in full-duplex mode (e.g., performing full-duplex wireless communication) or in half-duplex TDD mode (e.g., performing half-duplex TDD wireless communication). That is, full-duplex capability or half-duplex TDD capability (or both) may be present at one or more UEs 315, one or more network entities 305, or a combination thereof. For example, the network entity 305-e may be capable of full-duplex communication, which may enable simultaneous downlink transmission and uplink reception within the same component carrier. Additionally or alternatively, each wireless communication system 300 may illustrate a UE 315 operating in a multi-TRP mode, such that one or more of the UEs 315 may receive downlink communications (e.g., PDSCH transmissions) from multiple TRPs simultaneously. For example, each wireless communication system 300 may illustrate one or more multi-TRP PDSCH schemes. In some examples, such as Figure 3A As illustrated in the example of , UE 315-a can receive downlink communications from network entity 305-a and network entity 305-b simultaneously. In this example, network entity 305-a and network entity 305-b can be examples of TRPs serving the same cell (e.g., a cell providing coverage area 310-a). In some examples, downlink communications received by UE 315-a (e.g., from network entity 305-a and network entity 305-b) can occur concurrently with uplink communications sent by UE 315-b to network entity 305-c (e.g., serving a cell providing coverage area 310-b). In such examples, uplink communications sent by UE 315-b may cause inter-cell cross-link interference 340 at UE 315-a.
[0106] In other examples, such as Figure 3B As illustrated in the example of , UE 315-c can receive downlink communications from network entity 305-d and network entity 305-e simultaneously. In such examples, network entity 305-d and network entity 305-e can be examples of TRPs serving the same cell (e.g., a cell providing coverage area 310-c), and network entity 305-e can serve both UE 315-c and UE 315-d. In some examples, downlink communications received by UE 315-c (e.g., from network entity 305-d and network entity 305-e) can occur concurrently with uplink communications sent by UE 315-d to network entity 305-e. In this example, uplink communications sent by UE 315-d may cause intra-cell cross-link interference 341 at UE 315-c.
[0107] In some examples, the wireless communication system 300 can support one or more single downlink control information (DCI) PDSCH schemes, such as a TDM scheme, an FDM scheme, a spatial division multiplexing (SDM) scheme, or a single frequency network (SFN) scheme. In some examples, a single DCI PDSCH scheme can refer to a multi-TRP deployment, where PDSCH reception (e.g., scheduled by a single DCI) can be associated with multiple (e.g., two) TCI states (e.g., one TCI state for each TRP configured for communication with the UE 315). For example, Figure 3A As illustrated in the example of , network entity 305-a and network entity 305-b may be synchronized such that UE 315-a may receive a single DCI message (e.g., from network entity 305-a or network entity 305-b) that schedules PDSCH reception from network entity 305-a and network entity 305-b (e.g., multiple TRPs). In some examples, UE 315-a may indicate (e.g., to the network) the ability to perform single DCI PDSCH reception using multiple (e.g., two) beams via an IE (such as a defaultTwoBeams IE).
[0108] In some examples of a single DCI PDSCH scheme, UE 315-a may receive downlink communications (e.g., PDSCH transmissions) from network entity 305-a via a first receive beam associated with a first TCI state (e.g., a first PDSCH beam (not shown)), and receive PDSCH transmissions from network entity 305-b via a second PDSCH beam (not shown) associated with a second TCI state. In such examples, the inter-cell cross-link interference 340 experienced by UE 315-a for the first PDSCH beam may be different from the inter-cell cross-link interference 340 experienced by UE 315-a for the second PDSCH beam. Therefore, the network may configure UE 315-a to measure and report inter-cell cross-link interference 340 using one or more TCI states.
[0109] For example, the network may configure UE 315-a to determine whether to use a single TCI state (e.g., a single PDSCH beam) or a dual TCI state (e.g., a dual PDSCH beam) to perform cross-link interference measurements. For single TCI state cross-link interference measurements, the network may configure UE 315-a to use a single PDSCH beam (e.g., a first PDSCH beam or a second PDSCH beam) or a default beam. In some examples, the network may configure UE 315-a to report one or more metrics associated with a cross-link interference metric (e.g., a cross-link interference metric). That is, the network may configure UE 315-a to report one or more cross-link interference metrics corresponding to the cross-link interference measurement. For example, the network may configure UE 315-a to report a single metric (e.g., one metric corresponding to cross-link interference measurements performed using both a first PDSCH beam associated with a first TCI state and a second PDSCH beam associated with a second TCI state) or two metrics (e.g., one metric corresponding to cross-link interference measurements performed using a first PDSCH beam associated with a first TCI state and one metric for cross-link interference measurements performed using a second PDSCH beam associated with a second TCI state).
[0110] In some examples, if UE 315-a is configured to report a single metric, UE 315-a may report (e.g., indicate) a cross-link interference metric (e.g., which PDSCH beam is used to receive PDSCH transmissions) associated with a TCI state that may be experiencing an increased amount of cross-link interference. Additionally or alternatively, in some examples, the network may configure UE 315-a to perform filtering (e.g., filtering of cross-link interference measurements to reduce the effects of fading or other channel impairments on measurements performed by UE 315-a) via the same filter across two PDSCH beams (e.g., the same filter for both a first PDSCH beam associated with a first TCI state and a second PDSCH beam associated with a second TCI state) or a different filter for each of the PDSCH beams (e.g., a first filter for the first PDSCH beam associated with the first TCI state and a second filter for the second PDSCH beam associated with the second TCI state).
[0111] Additionally or alternatively, for example, if multiple TRPs (eg, network entities 305) are not synchronized or are partially synchronized, the wireless communication system 300 may support one or more multi-DCI PDSCH schemes. Figure 3BAs illustrated in the example of , UE 315-c can receive a DCI message from network entity 305-d that schedules PDSCH reception from network entity 305-d, and receive another DCI message from network entity 305-e that schedules PDSCH reception from network entity 305-e. In some examples, a structure associated with a multi-DCI PDSCH scheme (e.g., a DCI structure for scheduling PDSCH reception) may include one or more features that are the same as a carrier aggregation deployment. Additionally or alternatively, for some multi-DCI PDSCH schemes, downlink reception and uplink transmission (e.g., scheduled for UE 315-c) can each be associated with a specific control resource set identifier (e.g., indicated via a CORESETPoolIndex IE). For example, the network can configure UE 315-c to monitor multiple control resource sets associated with corresponding control resource set identifiers, and the value of each control resource set identifier can indicate a TCI state associated with a TRP (e.g., network entity 305).
[0112] In some examples of a multi-DCI PDSCH scheme, UE 315-c may receive downlink communications (e.g., PDSCH transmissions) from network entity 305-d via a first receive beam (e.g., a first PDSCH beam) associated with a first TCI state, and receive PDSCH transmissions from network entity 305-e via a second PDSCH beam associated with a second TCI state. In such examples, the intra-cell cross-link interference 341 experienced by UE 315-c for the first PDSCH beam may be different from the intra-cell cross-link interference 341 experienced by UE 315-c for the second PDSCH beam. Therefore, the network may configure UE 315-c to measure and report cross-link interference using one or more TCI states.
[0113] In some examples, the network may configure the UE 315-c to perform cross-link interference measurements at multiple occasions (e.g., time occasions, measurement occasions). In such examples, the network may configure the UE 315-c to determine a PDSCH beam (or multiple PDSCH beams) for performing cross-link interference measurements at each of the multiple occasions. In some examples, the network may configure the UE 315-c to perform cross-link interference measurements (e.g., associated with the network entity 305-d, the network entity 305-e, or both) using a PDSCH beam (e.g., indicated by the network to the UE 315-c) or a default beam based on the value of a control resource set identifier (e.g., based on whether the value of CORESETPoolIndex is equal to 0 or 1). In this example, the network may configure UE 315-c to report cross-link interference measurements performed at multiple occasions to network entity 305-d and network entity 305-e (e.g., independently to each TRP), or the network may configure UE 315-c to report (e.g., jointly report) cross-link interference measurements performed at multiple occasions to network entity 305-d or network entity 305-e (e.g., to one TRP).
[0114] In some examples, by performing cross-link interference measurements based on one or more TCI states, UE 315 can achieve increased granularity in cross-link interference measurements, thereby providing one or more enhancements to cross-link interference mitigation at the network, as well as other benefits.
[0115] Figure 4 An example of a wireless communication system 400 that supports cross-link interference measurement and reporting in a multi-TRP system according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 400 can implement aspects of the wireless communication system 100, the wireless communication system 200, and the wireless communication system 300. For example, the wireless communication system 400 may include one or more network entities 405 (e.g., network entity 405-a, network entity 405-b, and network entity 405-c) and one or more UEs 415 (e.g., UE 415-a and UE 415-b), which may be as described in reference Figure 1 , Figure 2 , Figure 3A and Figure 3B Examples of corresponding devices described. Figure 4 In the example of FIG. 1 , the network entities 405 may each be as shown in FIG. Figure 1 Examples of CU, DU, RU, base station, IAB node, TRP, or one or more other network nodes are described. The wireless communication system 400 may include features for improving communication between the UE 415 and the network, as well as other benefits.
[0116] exist Figure 4 In the example of , UE 415 and network entity 405 may communicate via one or more communication links. For example, UE 415-a may receive communications (e.g., downlink communications) from network entity 405-a via communication link 420-a and receive communications from network entity 405-b via communication link 420-b. Figure 4 In the example of , communication link 420 can be an example of a downlink. Additionally or alternatively, UE 415-a can send communications (e.g., uplink communications) to network entity 405-c via communication link 430, which can be an example of an uplink. Communication link 430 and communication link 420 can each be as described in reference Figure 1 An example of a communication link 125 is described.
[0117] In some examples, UE 415-a (e.g., and UE 415-b) can be configured to operate in a multi-TRP mode so that one or more UEs 415 can simultaneously receive downlink signals (e.g., PDSCH transmissions) from multiple TRPs (e.g., network entity 405). For example, UE 415-a can be configured to operate according to a multi-TRP PDSCH scheme. In some examples, such as Figure 4 As illustrated in the example of , UE 415-a may receive PDSCH transmissions from network entity 405-a and network entity 405-b simultaneously. Additionally or alternatively, UE 415-a and UE 415-b may be configured to concurrently perform half-duplex TDD communications (e.g., or full-duplex communications) such that PDSCH transmissions received by UE 415-a may overlap (e.g., in time) with uplink communications (e.g., PUSCH transmissions or PUCCH transmissions) sent by UE 415-b. In this example, UE 415-a and UE 415-b may be spatially positioned such that uplink communications sent by UE 415-b may cause cross-link interference 440 at UE 415-a. In some examples, UE 415-a and UE 415-b may be operating in the same cell. In this example, cross-link interference 440 may be as described in reference to FIG. Figure 3B In some other examples, UE 415-a may be operating in a cell different from the cell in which UE 415-b may be operating. In such examples, cross-link interference 440 may be as described in reference Figure 3A An example of inter-cell cross-link interference is described.
[0118] In some examples, if UE 415-a operates in a multi-TRP framework, UE 415-a may receive PDSCH transmissions from network entity 405-a via receive beam 435-a (e.g., first PDSCH beam) associated with first TCI state 410, and receive PDSCH transmissions from network entity 405-b via receive beam 435-b (e.g., second PDSCH beam) associated with second TCI state 411. In such examples, the cross-link interference 440 experienced by UE 415-a for receive beam 435-a (e.g., associated with first TCI state 410) may be different from the cross-link interference 440 experienced by UE 415-a for receive beam 435-b (e.g., associated with second TCI state 411). Therefore, to mitigate cross-link interference 440, the network (e.g., network entity 405-a or network entity 405-b) may configure UE 415-a to perform cross-link interference measurements using the first TCI state 410, the second TCI state 411, or both.
[0119] In some examples, the network may configure UE 415-a to apply a timing offset so that cross-link interference measurements for uplink transmissions (e.g., sent by UE 415-b) may be aligned. That is, for cross-link interference measurements (e.g., SRS-RSRP measurements and CLI-RSSI measurements), UE 415-a may apply an offset (e.g., a constant offset, a timing advance offset) relative to the downlink reference timing in the serving cell. In some examples, an offset value (e.g., a timing advance offset value) may be derived based on the uplink timing of a TRP (e.g., an uplink timing associated with network entity 405-a or network entity 405-b) from which UE 415-a may be receiving downlink communications (e.g., PDSCH transmissions). For example, PDSCH transmissions from multiple TRPs may not be synchronized (e.g., for multiple DCI frames). In this example, the network may indicate one or more timing offsets (e.g., timing advance offsets) for performing cross-link interference measurements. For example, the network may instruct UE 415-a to apply a timing advance offset associated with network entity 405-a, network entity 405-b, or both. That is, UE 415-a may select an offset value based on a TRP associated with a downlink receive beam used to perform cross-link interference measurements. Additionally or alternatively, the offset value may be determined based on a metric associated with uplink timing offsets of two TRPs (e.g., associated with network entity 405-a and network entity 405-b). In some examples, the metric may correspond to a maximum timing offset value (e.g., max(TA1, TA2)), a minimum timing offset value (e.g., min(TA1, TA2)), an average timing offset value (e.g., mean(TA 1, TA2)), or other suitable timing offset values.
[0120] For example, the network may configure UE 415-a to perform cross-link interference measurements (e.g., SRS-RSRP measurements or CLI-RSSI measurements) in a multi-TRP framework in which a PDSCH transmission received by UE 415-a is associated with multiple TCI states. In this example, the timing of an uplink transmission (e.g., transmitted by UE 415-b and measured by UE 415-a) may be associated with multiple timing offsets (e.g., timing advance offsets) and multiple power controls. That is, the timing advance offsets associated with receive beam 435-a and receive beam 435-b may be different, and therefore, the timing of the uplink transmission measured by UE 415-a via receive beam 435-a may be different from the timing of the uplink transmission measured via receive beam 435-b. In such examples, the network may configure UE 415-a to measure cross-link interference (e.g., determine a cross-link interference metric) using a single receive beam (e.g., a single TCI state) or dual receive beams (e.g., two TCI states). In some examples, if the network configures UE 415-a to (e.g., instructs it to) measure cross-link interference using a single receive beam (e.g., receive beam 435-a or receive beam 435-b), the network may indicate to UE 415-a which receive beam 435 UE 415-a may use to perform cross-link interference measurements. For example, the network may instruct UE 415-a to perform cross-link interference measurements using the first TCI state 410 or the second TCI state 411.
[0121] In some examples, the network may configure UE 415-a with resources (e.g., SRS resources) for performing cross-link interference measurements based on multiple TCI states. For example, the network may configure the UE to have multiple resources (e.g., resource sets, symbols) for each TCI state. In this example, each measurement (e.g., on a particular resource) may be associated with one of two TCI states for PDSCH transmission (e.g., one of two TCI states for receiving PDSCH transmission, receive beam 435-a or receive beam 435-b). Additionally or alternatively, the network may (e.g., jointly) configure resources for two TCI states. In this example, each measurement (e.g., on the configured resources) may be associated with two TCI states (e.g., two TCI states for receiving PDSCH transmission, receive beam 435-a and receive beam 435-b).
[0122] In some examples, the network may indicate whether (e.g., and how) the UE 415-a may filter the cross-link interference measurement (or a cross-link interference metric corresponding to the cross-link interference measurement). For example, the network may configure the UE 415-a to use the same filter (e.g., the same L3 filtering) across two TCI states (e.g., the first TCI state 410 and the second TCI state 411) or to use different filters (e.g., different L3 filtering) between the two TCI states (e.g., a first filter for the first TCI state 410 and a second filter for the second TCI state 411).
[0123] Additionally or alternatively, if the network instructs UE 415-a to measure cross-link interference using dual beams (e.g., receive beam 435-a and receive beam 435-b), the network may instruct UE 415-a to report multiple cross-link interference metrics (e.g., associated with each TRP) or a single cross-link interference metric (e.g., associated with one of the multiple TRPs, or an average metric associated with all TRPs). For example, the network may configure UE 415 to report a cross-link interference metric associated with the first TCI state 410, a cross-link interference metric associated with the second TCI state 411, or a cross-link interference metric associated with both the first TCI state 410 and the second TCI state 411 (e.g., an average cross-link interference metric).
[0124] In some examples, the network may configure UE 415-a to perform cross-link interference measurements across multiple occasions (e.g., different cross-link interference resource sets) using multiple receive beams (e.g., based on two different quasi-co-location relationships associated with separate TCI states). In such examples, the network may configure UE 415-a to filter cross-link interference measurements across multiple occasions and report a single cross-link interference metric. For example, UE 415-a filters cross-link interference measurements across two occasions, where cross-link interference measurements are performed using two receive beams, and reports an average (e.g., linear average, linear weighted average) of the two cross-link interference metrics, where each of the two cross-link interference metrics corresponds to a cross-link interference mismeasurement performed at one of the two occasions using one of the two receive beams.
[0125] Additionally or alternatively, the network may configure UE 415-a to report a filtered average of two cross-link interference metrics measured using different receive beams. For example, UE 415-a may filter the cross-link interference measurement according to the following equation 2 (e.g., before reporting the associated cross-link interference metric):
[0126] F n (i)=(1-a(i))*F n-1 (i)+a(i)*M n (2)
[0127] where F n (i) may represent filtered cross-link interference measurements (e.g., updated filtering results) that may be reported to the network (e.g., used by UE 415-a for evaluating reporting criteria or for cross-link interference measurement reporting). n (i) may be an index from 0 to 1 (e.g., i=0, 1), where a value of 0 may correspond to a first receive beam (e.g., receive beam 435-a associated with the first TCI state 410) and a value of 1 may correspond to a second receive beam (e.g., receive beam 435-b associated with the second TCI state 411). Additionally or alternatively, M n Can represent the relative last determined cross-link interference measurement (e.g., the relative last cross-link interference measurement result received from the physical (PHY) layer at the RRC layer). Additionally or alternatively, a(i) can represent a filter coefficient. In some examples, the network can configure UE 415-a to report two different filtered cross-link interference metrics (e.g., filtered cross-link interference metrics of two cross-link interference metrics) and a linear average of the two cross-link interference metrics. In some examples, the network can configure UE 415-a to have two filter coefficients (e.g., for i=0, 1, a(i)), for example, via filterCoefficient IE.
[0128] In some examples, the network may configure UE 415-a to compare multiple cross-link interference metrics and select (e.g., report to the network) a cross-link interference metric associated with an increased amount of interference (e.g., a cross-link interference metric associated with a relatively high value). For example, the network may configure UE 415-a to discard a cross-link interference metric (e.g., from among multiple cross-link interference metrics) based on determining that the cross-link interference metric fails to meet a threshold (or corresponds to a reduced amount of cross-link interference compared to other cross-link interference metrics in the multiple cross-link interference metrics). In this example, UE 415-a may report another cross-link interference metric (e.g., from among multiple cross-link interference metrics) or an average of other cross-link interference metrics.
[0129] In some examples, the network may configure UE 415-a to perform cross-link interference measurements and reporting via control signaling. For example, the network may send control signaling that may include parameters (e.g., RRC parameters, such as CORESETPoolIndex IE) for indicating to UE 415-a the association between resources (e.g., time and frequency resources) for performing cross-link interference measurements and each TRP. That is, the network may configure UE 415-a to have resources (e.g., cross-link interference resources) for performing cross-link interference measurements, which may be associated with each network entity 405 configured to communicate with UE 415-a. In some examples, the control signaling may include such parameters for each cross-link interference resource scheduled for UE 415-a (e.g., each indicated cross-link interference resource). In some examples, the cross-link interference resource may be an SRS resource such as may be indicated via SRS-ResourceConfigCLI-r16IE. Additionally or alternatively, the cross-link interference resource may be an RSSI resource such as may be indicated via an RSSI-ResourceConfigCLI-r16 IE.
[0130] Additionally or alternatively, the network may configure UE 415-a to perform cross-link interference measurements and reporting based on one or more PDSCH transmissions received by UE 415-a or one or more control resource sets monitored by UE 415-a. For example, if a relatively last PDSCH transmission (e.g., a relatively last received PDSCH transmission) or a relatively last control resource set (e.g., a relatively last monitored control resource set) is associated with multiple (e.g., two) TCI states, UE 415-a may determine (e.g., indicated to UE 415-a for performing cross-link interference measurements) that a cross-link interference resource is quasi-co-located with one or two TCI states in the TCI states associated with the PDSCH transmission or control resource set (e.g., D-type quasi-co-located with the spatial parameters of the receive beam). For example, UE 415-a may determine that a cross-link interference resource is quasi-co-located with a first TCI state 410, a second TCI state 411, or both. That is, the UE 415 may perform cross-link interference measurements based on a single quasi co-site relationship associated with at least one of two TCI states associated with a relatively last received PDSCH transmission or a relatively last monitored control resource set.
[0131] Additionally or alternatively, UE 415 may determine that the cross-link interference resource is quasi-co-located with a TCI state having a relatively lowest identifier or a relatively highest identifier (e.g., relative to other configured TCI states). For example, UE 415-a may perform cross-link interference measurements based on a quasi-co-located relationship associated with a TCI state (e.g., a first TCI state 410, a second TCI state 411), which TCI state may correspond to the lowest TCI state identifier or the highest TCI state identifier of two TCI states associated with a relatively last received PDSCH transmission or a relatively last monitored control resource set (e.g., associated with two TCI states).
[0132] Additionally or alternatively, UE 415-a may perform cross-link interference measurements at multiple occasions (e.g., measurement occasions, time occasions). In this example, UE 415 may determine that the cross-link interference resource is quasi-co-located with the first TCI state 410 for the first occasion, and is quasi-co-located with the second TCI state 411 for the second occasion. That is, UE 415 may perform cross-link interference measurements based on alternating TCI states, for example, via TDM. For example, UE 415-a may perform a first set of cross-link interference measurements based on a first quasi-co-location relationship associated with the first TCI state 410 at a first occasion (e.g., a first one or more cross-link interference resources), and perform a second set of cross-link interference measurements based on a second quasi-co-location relationship associated with the second TCI state 411 at a second occasion (e.g., a second one or more cross-link interference resources). In some examples, UE 415-a may determine that the cross-link interference resource is quasi-co-located with both the first TCI state 410 and the second TCI state 411. For example, UE 415 may perform cross-link interference measurement based on two quasi co-location relationships, one of which is associated with a first TCI state 410 and the other of which is associated with a second TCI state 411.
[0133] In some examples, if UE 415-a performs two cross-link interference measurements on a single cross-link interference resource (e.g., on a single time and frequency resource) using each of two receive beams (or using two uplink timing offsets), each of the two cross-link interference measurements can be counted (e.g., as two measurements) for the amount (e.g., a maximum amount or other acceptable amount) of CLI-SRS resource measurements that can be performed at UE 415-a (e.g., UE capabilities for CLI-SRS resource measurements). That is, when two cross-link interference measurements occur on the same time and frequency resources, the two cross-link interference measurements can occupy two cross-link interference resources out of a plurality of cross-link interference resources on which UE 415-a can perform cross-link interference measurements. Therefore, the network can configure UE 415-a to report the number (e.g., a maximum number or other suitable number) of cross-link interference resources on which UE 415-a can perform cross-link interference measurements. For example, UE 415-a may send an indication of UE capabilities associated with performing one or more cross-link interference measurements (e.g., the number of cross-link interference resources on which UE 415-a may be able to perform cross-link interference measurements). In this example, the network may configure (e.g., schedule) UE 415-a to have cross-link interference resources based on the reported UE capabilities.
[0134] In some examples, by configuring UE 415 with cross-link interference resources based on reported UE capabilities, the network can provide one or more enhancements to cross-link interference measurement and reporting at UE 415-a, as well as other benefits.
[0135] Figure 5 An example of a measurement scheme 500 for supporting cross-link interference measurement and reporting in a multi-TRP system according to one or more aspects of the present disclosure is illustrated. In some examples, the measurement scheme 500 can implement aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, and the wireless communication system 400. For example, the measurement scheme 500 can be implemented by one or more network entities and UEs, which can be as described in reference Figure 1 , Figure 2 , Figure 3A , Figure 3B and Figure 4 Examples of corresponding devices described. Figure 5 In the example of Figure 1 Examples of described CUs, DUs, RUs, base stations, IAB nodes, TRPs, or one or more other network nodes. The measurement scheme 500 may include features for improving communications between a UE and a network, among other benefits.
[0136] like Figure 5 As shown in the example of , the UE may perform cross-link interference measurements based on one or more TCI states. For example, the network may configure the UE to determine one or more TCI states for performing cross-link interference measurements based on one or more downlink communications (e.g., PDSCH transmissions) received by the UE or one or more control resource sets monitored by the UE. For example, if a PDSCH transmission (e.g., relative to the last received PDSCH transmission) or a control resource set (e.g., relative to the last monitored control resource set) is associated with multiple (e.g., two) TCI states, the UE may determine that the resources (e.g., cross-link interference resources) used to perform cross-link interference measurements are quasi-co-located with one or two TCI states in the TCI state (e.g., relative to the spatial parameters of one or more receive beams, relative to the D-type quasi-co-location parameters). For example, the PDSCH transmission relative to the last received (or the control resource set relative to the last monitored) may be associated with a first TCI state 510 and a second TCI state 511, and the network may configure the UE to perform cross-link interference measurements using the first TCI state 510, the second TCI state 511, or both the first TCI state 510 and the second TCI state 511.
[0137] In some examples, the UE may perform cross-link interference measurements using a single TCI state (e.g., a single quasi-co-site relationship associated with a single TCI state). For example, the network may configure the UE to TDM (e.g., cyclic) receive beams for performing cross-link interference measurements. For example, the network may configure the UE to perform cross-link interference measurements according to configuration 505-a. In this example, the UE may perform a first set of cross-link interference measurements based on a quasi-co-site relationship associated with a first TCI state 510, and perform a second set of cross-link interference measurements based on a quasi-co-site relationship associated with a second TCI state 511. For example, the UE may receive a PDSCH transmission from a first network entity (not shown) on one or more first resources 520 (e.g., first resource 520-a and first resource 520-b) via one or more receive beams 515 (e.g., receive beam 515-a and receive beam 515-d) that may be associated with the first TCI state 510.
[0138] Additionally or alternatively, the UE may receive PDSCH transmissions from a second network entity (not shown) on one or more second resources 521 (e.g., second resource 521-a and second resource 521-b) via one or more other receive beams 515 (e.g., receive beam 515-b and receive beam 515-e) that may be associated with the second TCI state 511. In this example, the UE may perform a first set of cross-link interference measurements on a cross-link interference resource 522-a using a receive beam 515-c that may be determined by the UE based on a quasi-co-location relationship associated with the first TCI state 510. That is, the UE may perform a first set of cross-link interference measurements using the first TCI state 510. Additionally or alternatively, the UE may perform a second set of cross-link interference measurements on a cross-link interference resource 522-b using a receive beam 515-f that may be determined by the UE based on a quasi-co-location relationship associated with the second TCI state 511. That is, the UE may perform a second set of cross-link interference measurements using the second TCI state 511.
[0139] Additionally or alternatively, UE 415-a may perform cross-link interference measurements using two TCI states (e.g., two quasi-co-site relationships associated with the two TCI states). For example, the network may configure the UE to perform cross-link interference measurements according to configuration 505-b. In this example, the UE may perform cross-link interference measurements based on two quasi-co-site relationships, wherein one of the two quasi-co-site relationships is associated with a first TCI state 510 and the other of the two quasi-co-site relationships is associated with a second TCI state 511. That is, the UE may use a portion (e.g., half) of the cross-link interference resources to perform cross-link interference measurements using a receive beam associated with the first TCI state 510, and use another portion (e.g., the other half) of the cross-link interference resources to perform cross-link interference measurements using a receive beam associated with the second TCI state 511 (e.g., if the UE is configured to have multiple symbols for each cross-link interference resource). In this example, the network may configure the UE with multiple cross-link interference resources that may accommodate (eg, take into account) the gaps so that the UE may switch (eg, change, replace) receive beams (eg, for performing measurements).
[0140] For example, the UE may receive a PDSCH transmission from a first network entity (not shown) on a first resource 520-c via a receive beam 515-g that may be associated with a first TCI state 510. Additionally or alternatively, the UE may receive a PDSCH transmission from a second network entity (not shown) on a second resource 521-c via a receive beam 515-h that may be associated with a second TCI state 511. In this example, the UE may perform cross-link interference measurements on a cross-link interference resource 522-c using a receive beam 515-i that may be determined by the UE based on a quasi-co-location relationship associated with the first TCI state 510, and the UE may perform cross-link interference measurements on a cross-link interference resource 522-d using a receive beam 515-j that may be determined by the UE based on a quasi-co-location relationship associated with the second TCI state 511.
[0141] In some examples, by configuring the UE to perform cross-link interference measurements based on one or both of the first TCI state 510 and the second TCI state 511, the UE can provide one or more enhancements to cross-link interference mitigation performed by the network, thereby increasing the reliability of communications between the UE and the network, as well as other benefits.
[0142] Figure 6 An example of a measurement scheme 600 for supporting cross-link interference measurement and reporting in a multi-TRP system according to one or more aspects of the present disclosure is illustrated. In some examples, the measurement scheme 600 can implement aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, and the wireless communication system 400. For example, the measurement scheme 600 can be implemented by one or more network entities and one or more UEs, which can be as described in reference Figure 1 , Figure 2 , Figure 3A , Figure 3B and Figure 4 Examples of corresponding devices described. Figure 6 In the example of Figure 1 Examples of described CUs, DUs, RUs, base stations, IAB nodes, TRPs, or one or more other network nodes. The measurement scheme 600 may include features for improving communications between a UE and a network, among other benefits.
[0143] like Figure 6As shown in the example of , the UE may perform cross-link interference measurements based on multiple TCI states. For example, the UE may perform cross-link interference measurements using multiple beams, where each of two beams is determined by the UE based on a corresponding quasi-co-location relationship associated with the TCI state. For example, the UE may be configured to operate in a multi-TRP mode so that the UE may simultaneously receive downlink communications (e.g., PDSCH transmissions) from two network entities, which may each be associated with a corresponding TCI state. For example, the UE may simultaneously receive PDSCH transmissions from a first network entity (not shown) on one or more first resources 620 (e.g., first resource 620-a and first resource 620-b) via one or more receive beams 615 (e.g., receive beam 615-a and receive beam 615-e) that may be associated with a first TCI state 610. Additionally or alternatively, the UE may receive a PDSCH transmission from a second network entity (not shown) on one or more second resources 621 (e.g., second resource 621-a and second resource 621-b) via one or more receive beams 615 (e.g., receive beam 615-b and receive beam 615-f) that may be associated with the second TCI state 611.
[0144] In some examples, the UE may be configured to operate according to an SDM scheme, an SFN scheme, or a multi-DCI PDSCH mode, where PDSCH transmissions from a first network entity and a second network entity may overlap in time and frequency. In such examples, the first resource 620-a and the second resource 621-a may overlap in time and frequency, and the UE may perform cross-link interference measurements according to configuration 605-a. That is, the UE may perform cross-link interference measurements on the cross-link interference resource 622-a using receive beam 615-c and receive beam 615-d. In some examples, the UE may determine receive beam 615-c based on a quasi-co-location relationship associated with the first TCI state 610, and the UE may determine receive beam 615-d based on a quasi-co-location relationship associated with the second TCI state 611.
[0145] Additionally or alternatively, in some examples, the UE may be configured to operate according to an FDM scheme (e.g., for receiving PDSCH transmissions from both a first network entity and a second network entity). In some examples of the FDM scheme, the first resource 620-b and the second resource 621-b may overlap in time and may not overlap in frequency. In such examples, the UE may perform cross-link interference measurements according to configuration 605-b. For example, the UE may perform cross-link interference measurements on cross-link interference resource 622-b using receive beam 615-g and receive beam 615-h. In this example, the UE may determine receive beam 615-f based on a quasi-co-site relationship associated with the first TCI state 610, and the UE may determine receive beam 615-g based on a quasi-co-site relationship associated with the second TCI state 611. The UE may perform cross-link interference measurements using a first set of cross-link interference resources 622-b that may be aligned with a first resource 620-b of a first TCI state 610 using a first receive beam (e.g., receive beam 615-e). Additionally or alternatively, the UE may perform cross-link interference measurements using a second set of cross-link interference resources 622-b that may be aligned with a second resource 621-b of a second TCI state 611 using a second receive beam (e.g., receive beam 615-f).
[0146] In some examples, by performing cross-link interference measurements using two receive beams 615 (e.g., each receive beam is associated with a respective TCI state), the UE can achieve granularity in cross-link interference measurements (e.g., increased granularity of SRS-RSRP measurements).
[0147] Figure 7 An example of a process flow 700 for supporting cross-link interference measurement and reporting in a multi-TRP system according to one or more aspects of the present disclosure is illustrated. The process flow 700 may implement or be implemented by one or more aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, and the wireless communication system 400. For example, the process flow 700 may include a network entity 705 and a UE 715, which may be as described in reference Figure 1 , Figure 2 , Figure 3A , Figure 3B and Figure 4 Examples of corresponding devices described. Process flow 700 can be implemented by network entity 705, UE 715, or both. In the following description of process flow 700, operations between network entity 705 and UE 715 can occur in a different order or at a different time than shown. Some operations can also be omitted from process flow 700, and other operations can be added to process flow 700.
[0148] At 720, UE 715 may receive a message indicating a cross-link interference configuration from network entity 705. The cross-link interference configuration may correspond to a configuration for measuring cross-link interference associated with UE 715. In some examples, the cross-link interference configuration sent at 720 may be as described in reference Figure 2 Examples of described cross-link interference configurations. For example, a cross-link interference configuration may indicate one or more TCI states for use by UE 715 to perform one or more cross-link interference measurements.
[0149] In some examples, UE 715 can perform one or more cross-link interference measurements according to the cross-link interference configuration. For example, at 725, UE 715 can perform one or more cross-link interference measurements on a cross-link interference resource set using one or more TCI states. In some examples, UE 715 can operate in a multi-TRP framework. In such examples, UE 715 can perform cross-link interference measurements (e.g., SRS-RSRP measurements and CLI-RSSI measurements) on multiple occasions (e.g., cross-link interference measurement opportunities), wherein each cross-link interference measurement opportunity includes a portion of the cross-link interference resource. In such examples, UE 715 can perform cross-link interference measurements based on one or more quasi-co-site relationships and one or more timing offsets, and the one or more quasi-co-site relationships and the one or more timing offsets can each be associated with a corresponding TCI state in one or more TCI states.
[0150] In some examples, UE 715 may perform one or more cross-link interference measurements using dual receive beams. For example, UE 715 may perform one or more cross-link interference measurements based on two quasi-co-location relationships, wherein each of the two quasi-co-location relationships is associated with a corresponding TCI state in one or more TCI states. In this example, a single cross-link interference metric may be generated. Additionally or alternatively, UE 715 may perform one or more cross-link interference measurements using a single receive beam. For example, UE 715 may perform one or more cross-link interference measurements based on a single quasi-co-location relationship associated with a TCI state in one or more TCI states. In this example, UE 715 may generate two cross-link interference metrics (e.g., two cross-link interference measurement opportunities based on using different quasi-co-location relationships to perform cross-link interference measurements). For example, UE 715 may generate two cross-link interference metrics, wherein each cross-link interference metric may be associated with a TRP (e.g., a network entity). That is, UE 715 may generate two cross-link interference metrics, each of which may correspond to a cross-link interference measurement performed using a receive beam determined using a quasi-co-location relationship associated with the TCI state of the TRP. In this example, UE 715 may report each of the two cross-link interference metrics or a single (e.g., combined, averaged) cross-link interference metric. In some examples, if UE 715 combines the two cross-link interference metrics, the combined cross-link interference metric may correspond to a linear average of the two cross-link interference metrics or a filtered average of the two cross-link interferences.
[0151] In some examples, at 730, the UE may send a cross-link interference report indicating one or more cross-link interference metrics corresponding to one or more cross-link interference measurements. In this example, if the UE 715 performs two measurements at 725 (e.g., on two cross-link interference resources) and generates two cross-link interference metrics (e.g., one cross-link interference metric for each cross-link interference resource), the UE 715 may report two cross-link interference metrics for each cross-link interference resource. Additionally or alternatively, the UE 715 may report a single (e.g., combined) cross-link interference metric for each cross-link interference resource. In some examples, after performing the cross-link interference measurement, the UE 715 may perform threshold processing. For example, the UE 715 may compare each of the two cross-link interference metrics with (e.g., relative to) a threshold value, and remove (e.g., discard) one of the cross-link interference metrics before sending the cross-link interference report at 730 (or before averaging the cross-link interference metrics).
[0152] In some examples, if UE 715 reports two cross-link interference metrics (e.g., via a cross-link interference report sent at 730), UE 715 may send cross-link interference measurements according to the ordering. In some examples, the ordering may be based on the value of the identifier of the corresponding TCI state (e.g., the value of the corresponding CORESETPoolIndex IE). That is, the ordering may be based on the order of the control resource sets associated with each TCI state in one or more TCI states (e.g., the control resource set order). In some examples, if UE 715 reports one or more cross-link interference metrics for each cross-link interference resource, the ordering of the cross-link interference metrics may be based on the value of the identifier of the corresponding TCI state. For example, a first cross-link interference metric may correspond to a first TCI state (e.g., a TCI state corresponding to a control resource set in which CORESETPoolindex IE is set to 0). Additionally or alternatively, the ordering may be based on the strength (e.g., value) of the cross-link interference measurement. That is, UE 715 may send cross-link interference metrics in ascending order of corresponding values (e.g., and report the associated TCI states in the corresponding order of corresponding values).
[0153] In some examples, by reporting one or more cross-link interference metrics at 730, UE 715 can enhance cross-link interference mitigation techniques performed by network entity 705, thereby increasing communication reliability between UE 715 and the network, among other benefits.
