Cross-link interference configuration for supporting multiple transmit-receive point operation under channel state information framework

Abstract

Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a network node may enable a user equipment (UE) to configure multiple transmit receive point (mTRP) operation in a manner that measures inter-UE cross-link interference (CLI) for each downlink receive beam, each downlink receive beam corresponding to a respective TRP communicating with the UE in a duplex mode with dynamic interference conditions (e.g., CLI and / or self-interference). For example, in order to support mTRP operation, a network node may send a CLI configuration to a UE that indicates a respective set of CLI measurement resources for each TRP configured to communicate with the UE, where each set of CLI measurement resources may include a set of interference measurement resources (IMRs) associated with the respective TRP, the UE is thereby configured to measure and report a CLI level for each channel measurement resource (CMR) associated with the TRP communicating with the UE.

[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Patent Application No. 18 / 365,162, filed August 3, 2023, entitled “CROSS-LINK INTERFERENCE CONFIGURATION UNDER CHANNEL STATE INFORMATION FRAMEWORK TO SUPPORT MULTIPLETRANSMISSION RECEPTION POINT OPERATION,” which is assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0003] All aspects of this disclosure relate to wireless communication in general, and more specifically to techniques, apparatus and methods associated with cross-link interference (CLI) configuration for supporting multiple transmit-receive-point (mTRP) operation within the framework of channel state information (CSI). Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of services, including voice, text, messaging, video, data, and / or other services. Services may include unicast, multicast, and / or broadcast services, etc. Typical wireless communication systems employ multiple access radio access technologies (RATs) capable of supporting communication with multiple users by sharing available system resources (e.g., time-domain resources, frequency-domain resources, spatial-domain resources, and / or device transmit power, etc.). Examples of such multiple access RATs include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single-Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0005] The aforementioned Multiple Access RATs have been adopted in various telecommunications standards to provide a common protocol enabling different wireless communication devices to communicate at the city, national, regional, or global level. An example telecommunications standard is New Radio (NR). NR (which can also be referred to as 5G) is part of the continuous evolution of mobile broadband announced by the 3rd Generation Partnership Project (3GPP). NR (and other mobile broadband evolutions besides NR) can be designed to better support the Internet of Things (IoT) and reduced-capacity device deployments, industrial connectivity, millimeter-wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelinks and other device-to-device direct communication technologies (e.g., cellular vehicle-to-everything (V2X) communications), massive MIMO, decomposed network architectures and network topology expansion, multi-subscriber implementations, high-precision positioning and / or radio frequency (RF) sensing, and more. As the demand for mobile broadband access continues to grow, further improvements to NR can be implemented, and other radio access technologies (such as 6G) can be introduced to further advance mobile broadband evolution.

[0006] In wireless networks, various duplex configurations can be supported to improve flexibility, spectral efficiency, latency, and / or other important communication parameters. For example, a wireless network can support dynamic time-division duplexing (TDD), where the allocation of network resources for uplink and / or downlink communication can be dynamically modified based on traffic load. For instance, a network node can be configured with a TDD configuration (e.g., TDD mode) that includes more uplink transmission time intervals (TTIs) for a UE with uplink data to transmit, and with a TDD configuration with more downlink TTIs when the UE has downlink data to receive. Additionally or alternatively, network nodes and / or UEs can be configured to operate in full-duplex mode to support concurrent transmission and reception (e.g., within the same time resources). This can reduce latency, enhance per-cell or per-UE spectral efficiency or throughput, and / or achieve more efficient resource utilization by simultaneously allocating time and frequency resources for downlink and uplink communication. However, dynamic TDD, full-duplex and / or other advanced duplex communication modes can be associated with dynamic interference conditions, including cross-link interference (CLI) and self-interference (SI).

[0007] For example, in a dynamic TDD configuration, adjacent network nodes may use different TDD configurations to communicate with the served UE, which can cause downlink transmissions from a first network node to a first UE and uplink transmissions from a second UE to a second network node to occur in the same TTI. In such cases, concurrent downlink and uplink transmissions may cause CLIs, such as downlink-to-uplink interference (sometimes referred to as inter-node CLI), where downlink transmissions by the first network node interfere with the ability of the second network node to receive uplink transmissions from the second UE. Additionally or alternatively, concurrent downlink and uplink transmissions may cause uplink-to-downlink interference (sometimes referred to as inter-UE CLI), where uplink transmissions by the second UE interfere with the ability of the first UE to receive downlink transmissions from the first network node. Furthermore, when one or more nodes (e.g., network nodes and / or UEs) transmit and receive in the same TTI, full-duplex communication may be associated with inter-cell CLI, intra-cell CLI, and / or SI. For example, an uplink transmission by a first UE in a cell may interfere with the reception of a concurrent downlink transmission by another UE in the same cell, resulting in intra-cell UE CLI. In another example, an uplink transmission by a first UE in a first cell may interfere with the reception of a downlink transmission by a second UE in a second cell, resulting in inter-cell UE CLI. Furthermore, SI can occur at any network node or UE communicating using a full-duplex configuration because the transmission of a first signal may interfere with the concurrent reception of a second signal (e.g., when the transmitted signal leaks into the receive port and / or when objects in the surrounding environment reflect the transmitted signal back to the receive port).

[0008] Therefore, because there are various duplex scenarios (e.g., dynamic TDD and / or full-duplex) that may cause the affected UE to experience inter-cell CLI, intra-cell CLI, SI, and / or other interference that may degrade downlink reception performance, network nodes can configure the affected UE to obtain measurements related to the interference experienced at the affected UE and report these measurements to the network node (e.g., to enable the network node to select appropriate downlink beamforming, resource allocation, and / or other communication parameters to mitigate the interference experienced at the affected UE). For example, the network node can use Layer 3 (L3) signaling (e.g., Radio Resource Control (RRC) messages) to configure static or semi-static periodic measurement resources for the UE, and the UE can use L3 messages to report interference measurements to the network node. Generally, using L3 signaling to configure periodic measurement resources and provide measurement reports that include interference measurements provides a low-complexity solution and low control overhead. However, using static or semi-static RRC signaling lacks flexibility and carries long delays when reporting CLI and / or SI. Summary of the Invention

[0030] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, aspects of this disclosure may be embodied in many different forms and should not be construed as limited to any specific aspect illustrated or described with reference to the drawings or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, various combinations or numbers of aspects set forth herein may be used to implement an apparatus or a method of practice. Furthermore, the scope of this disclosure is intended to cover apparatuses having structures and / or functionalities other than those available for practicing the various aspects of this disclosure set forth herein, or methods of practice using those other structures and / or functionalities. Any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0031] Various methods, operations, apparatuses, and techniques will now be presented with reference to them. These methods, operations, apparatuses, and techniques will be described in detail below and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0032] The various aspects collectively relate to cross-link interference (CLI) configuration within the Channel State Information (CSI) framework for supporting multiple transmit-receive-point (mTRP) operation. Some aspects more specifically relate to techniques for configuring mTRP operation in a manner that enables user equipment (UE) to measure inter-UE CLI for each downlink receive beam, each downlink receive beam corresponding to a suitable TRP communicating with the UE in sub-band full-duplex (SBFD), in-band full-duplex (IBFD), dynamic time-division duplex (TDD), and / or another suitable mode that may be subject to intra-cell CLI, inter-cell CLI, self-interference (SI), and / or other dynamic interference conditions. For example, to support or otherwise implement mTRP operation, a network node may send, and a UE may receive, a CLI configuration indicating a corresponding set of CLI measurement resources for each TRP configured to communicate with the UE, wherein each set of CLI measurement resources may include a set of interference measurement resources (IMRs) associated with the corresponding TRP, thereby configuring the UE to measure and report the CLI level of each channel measurement resource (CMR) (e.g., non-zero power (NZP) CMR) associated with the TRP communicating with the UE in mTRP mode.

[0033] Additionally or alternatively, shared space reception (Rx) parameters are used in different TRPs (e.g., in relation to Quasi-co-location (QCL) type D or qcl-TypeD In cases where a relatively wide beam (parameter-associated) communicates with the UE, the CLI configuration provided to the UE may indicate an IMR that can be used to measure one or more common (wider) Rx beams on one or more panels of the UE for the corresponding TRP. For example, in some aspects, the CLI configuration may typically include multiple sets of resource sets, where each resource set includes one or more CMRs and one or more CLI IMRs associated with those one or more CMRs, wherein the CLI IMRs in each resource set may be associated with one or more intruding UEs and / or one or more transmit (Tx) beams of those one or more intruding UEs (e.g., UEs that cause intra-cell or inter-cell CLIs). Furthermore, as described herein, some aspects may involve different mappings between CMRs and CLI IMRs included in the corresponding resource sets (e.g., depending on the use case associated with mTRP operation, the number of CMRs in each resource set may be less than, equal to, or greater than the number of CLI IMRs in the same resource set), techniques for reporting CLI levels to support mTRP operation, and / or assumptions that may be configured for the UE to report CLI levels to support mTRP operation, etc.

[0034] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques can be used to implement CLI measurement and reporting using a CSI framework, such that CLI measurements can be configured for use by the UE and / or reported by the UE using Layer 1 (L1) signaling (such as Downlink Control Information (DCI) and / or Uplink Control Information (UCI)) and / or using Layer 2 (L2) signaling (such as Media Access Control (MAC) Control Elements (MAC-CE)). In this way, an affected UE communicating in a dynamic TDD scenario or a full-duplex scenario and experiencing inter-UE CLI of an intruding UE can use L1 / L2 signaling to measure and report inter-UE CLI, which can be optimized for short-term interference measurements and / or lower latency (e.g., relative to a Layer 3 (L3) framework), and / or enable network nodes to adjust UE scheduling to reduce or mitigate inter-UE CLI.

[0035] Multiple access radio access technology (RAT) has been adopted in various telecommunications standards to provide a common protocol that enables different wireless communication devices to communicate at the city, national, regional, or global level. For example, New Radio (NR) (also known as 5G) is part of the 3rd Generation Partnership Project (3GPP) to better support the continuous evolution of mobile broadband, including: Internet of Things (IoT) and Reduced Capability (RedCap) device deployments, industrial connectivity, millimeter wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelinks and other device-to-device direct communication technologies, massive MIMO, decomposed network architectures and network topology expansion, multi-subscriber implementations, high-precision positioning and / or radio frequency (RF) sensing, and more. As the demand for mobile broadband access continues to increase, further improvements to NR can be made, and other RATs such as 6G can be introduced to further advance the evolution of mobile broadband (e.g., to support full-duplex or other advanced duplex schemes, artificial intelligence or machine learning, collaborative communications, large-scale and environmental IoT, enhanced modulation and decoding, new frequency bands, overlapping spectrum use and extended reality (XR), etc.).

[0036] Figure 1 This is a diagram illustrating an example of a wireless communication network 100 according to the present disclosure. The wireless communication network 100 may be a 5G (or NR) network or a 6G network, or may include elements of a 5G (or NR) network or a 6G network, etc. The wireless communication network 100 may include a plurality of network nodes 110 (also referred to as network entities), shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d. Network node 110 may support communication with a plurality of UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0037] Network node 110 may include one or more devices or systems that enable communication between UE 120 and one or more components of wireless communication network 100. Network node 110 may be, may include, or may be referred to as an NR network node, 5G network node, 6G network node, node B, eNB (e.g., in 4G), gNB (e.g., in 5G), access point (AP), transmit / receive point (TRP), network mobility element, core network node, network element, network equipment, and / or one or more devices of another type included in radio access network (RAN).

[0038] Network node 110 may be implemented as a single physical node (e.g., a single physical structure) or as two or more physical nodes (e.g., two or more different physical structures). For example, network node 110 may be a device or system implementing a portion of a radio protocol stack, a device or system implementing a complete protocol stack (such as a complete gNB protocol stack), or a collection of devices or systems collectively implementing a complete protocol stack. For example, and as shown, network node 110 may be an aggregated network node, meaning that network node 110 can implement a complete radio protocol stack physically and logically integrated within a single node (e.g., a single physical structure) in the wireless communication network 100. For example, aggregated network node 110 may consist of a single standalone base station or a single TRP that uses a complete radio protocol stack to implement or facilitate communication between UE 120 and the core network of wireless communication network 100.

[0039] Alternatively, and also as shown in the figure, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 can use protocol stacks that are physically distributed and / or logically distributed across two or more nodes in the same or different geographical locations. In some deployments, decomposed network node 110 can be used in integrated access and backhaul (IAB) networks, in open radio access networks (O-RAN) (such as network configurations initiated by the O-RAN Alliance), or in virtualized radio access networks (vRAN) (also referred to as cloud radio access networks (C-RAN)) to facilitate scaling of the communication system by decomposing base station functionality into multiple separately deployable units.

[0040] Network nodes 110 of the wireless communication network 100 may include one or more central units (CUs), one or more distributed units (DUs), and / or one or more radio units (RUs). CUs may host one or more higher-layer control functions, such as Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, and / or Service Data Adaptation Protocol (SDAP) functions, etc. DUs may host one or more of the Radio Link Control (RLC) layer, MAC layer, and / or one or more high physical (PHY) layers, at least in part, according to functional splits (such as functional splits defined by 3GPP). In some examples, DUs may also host one or more low-PHY layer functions, such as Fast Fourier Transform (FFT), Inverse FFT (iFFT), beamforming, Physical Random Access Channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, etc. RUs may host RF processing functions or low-PHY layer functions, such as FFT, iFFT, beamforming, or PRACH extraction and filtering, etc., according to functional splits (such as lower-layer functional splits). In this type of architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0041] In some aspects, network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. Additionally or alternatively, network node 110 may include one or more near real-time (near RT) RAN Intelligent Controllers (RICs) and / or one or more non-real-time (non-RT) RICs. In some examples, CUs, DUs, and / or RUs may be implemented as virtual units, such as Virtual Central Units (VCUs), Virtual Distributed Units (VDUs), or Virtual Radio Units (VRUs), etc. Virtual units may be implemented as virtual network functions, such as those associated with cloud deployments.

[0042] In some examples, network node 110 may be, may include, or operate as a RU, TRP, or base station communicating with one or more UEs 120 via a radio access link (which may be referred to as a "Uu" link). The radio access link may include a downlink and an uplink. A "downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and an "uplink" (or "UL") refers to the communication direction from UE 120 to network node 110. Downlink channels may include one or more control channels and one or more data channels. Downlink control channels may be used to transmit downlink control information (e.g., scheduling information, reference signals, and / or configuration information) from network node 110 to UE 120. Downlink data channels may be used to transmit downlink data (e.g., user data associated with UE 120) from network node 110 to UE 120. Downlink control channels may include one or more physical downlink control channels (PDCCH), and downlink data channels may include one or more physical downlink shared channels (PDSCH). The uplink channel may similarly include one or more control channels and one or more data channels. The uplink control channel can be used to transmit uplink control information (e.g., corresponding reference signals and / or feedback to one or more downlinks) from UE 120 to network node 110. The uplink data channel can be used to transmit uplink data (e.g., user data associated with UE 120) from UE 120 to network node 110. The uplink control channel may include one or more physical uplink control channels (PUCCH), and the uplink data channel may include one or more physical uplink shared channels (PUSCH). The downlink and uplink may each include a set of resources on which network node 110 and UE 120 can communicate.

[0043] In various examples, in addition to half-duplex operation, some network nodes and UEs in the wireless communication network 100, including network node 110 and UE 120, can also be configured for full-duplex operation. Network node 110 or UE 120 operating in half-duplex mode can perform only one of transmission or reception during a specific time resource period (such as a specific time slot, symbol, or other time period). Half-duplex operation may involve TDD, in which the DL transmission of network node 110 and the UL transmission of UE 120 do not occur in the same time resource (i.e., these transmissions do not overlap in time). In contrast, network node 110 or UE 120 operating in full-duplex mode can transmit and receive communications concurrently (e.g., in the same time resource). By operating in full-duplex mode, network node 110 and / or UE 120 can generally increase the capacity of the network and radio access links. In some examples, full-duplex operation may involve frequency division duplex (FDD), in which network node 110 performs DL transmission in a first frequency band or on a first component carrier, and UE 120 performs transmission in a second frequency band or on a second component carrier, the second frequency band or the second component carrier being different from the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for UE 120 but not for network node 110. For example, UE 120 may simultaneously transmit UL to the first network node 110 and receive DL transmissions from the second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for network node 110 but not for UE 120. For example, network node 110 may simultaneously transmit DL to the first UE 120 and receive UL transmissions from the second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both network node 110 and UE 120.

[0044] In some examples, UE 120 and network node 110 can perform MIMO communication. "MIMO" generally refers to the simultaneous transmission or reception of multiple signals (such as multiple layers or multiple data streams) using the same time and frequency resources. MIMO technology typically utilizes multipath propagation. MIMO can be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO can support simultaneous transmission to multiple receivers, which is called multi-user MIMO (MU-MIMO). Some RATs can employ advanced MIMO techniques such as mTRP operations (including redundant transmission or reception on multiple TRPs), reciprocity in the time or frequency domain, single-frequency network (SFN) transmission, or noncoherent joint transmission (NC-JT). Furthermore, in wireless local area networks (WLANs), one or more APs and one or more stations (STAs) with multiple antennas can also support spatial multiplexing, which can be used to improve spectral efficiency and the resulting throughput. To achieve spatial multiplexing, the transmitting device divides the data stream into several separate, independent spatial streams, which are then individually encoded and transmitted in parallel via multiple transmit antennas.

[0045] As described above, in some aspects, the wireless communication network 100 may be an IAB network, may include an IAB network, or may be included in an IAB network. In an IAB network, at least one network node 110 is an anchor network node communicating with a core network. The anchor network node 110 may also be referred to as an IAB donor (or "IAB donor"). The IAB donor 110 may be connected to the core network via a wired backhaul link. For example, the Ng interface of the IAB donor 110 may terminate at the core network. Additionally or alternatively, the IAB donor 110 may be connected to one or more devices in the core network that provide core access and mobility management functions (AMF). An IAB network typically also includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply IAB nodes (or "IAB-nodes"). Each IAB node 110 can directly communicate with IAB donor 110 to access the core network via a wireless backhaul link, or indirectly communicate with IAB donor 110 via one or more other IAB nodes 110 and an associated wireless backhaul link forming a backhaul path to the core network. Some IAB donors 110 or other IAB nodes 110 can also directly communicate with one or more UEs 120 via a wireless access link carrying access services. For example, network resources used for wireless communication (such as time resources, frequency resources, and / or spatial resources) can be shared between the access link and the backhaul link.

[0046] IAB donor 110 may include a CU capable of performing Access Node Controller (ANC) and / or AMF functions. The CU may configure the DU of IAB donor 110 and / or configure one or more IAB nodes 110 connected to the core network via IAB donor 110 (e.g., Mobile Terminal (MT) functions and / or the DU functions of each of the IAB nodes). Therefore, the CU of IAB donor 110 may control and / or configure the entire IAB network (or a portion thereof) connected to the core network via IAB donor 110, for example, by using control messages and / or configuration messages (e.g., RRC configuration messages or F1 Application Protocol (F1AP) messages).

[0047] In addition to the IAB donor 110, an IAB node 110 may also control and / or schedule communications for a second IAB node 110 (e.g., when an IAB node provides DU functionality for the MT function of a second IAB node). In such a deployment, the first IAB node 110 may be referred to as the parent IAB node of the second IAB node 110, and the second IAB node 110 may be referred to as the child IAB node of the first IAB node 110. Similarly, the child IAB node of the second IAB node 110 may be referred to as the grandchild IAB node of the first IAB node 110. The DU functionality of the parent IAB node may control and / or schedule communications for the child IAB nodes of the parent IAB node. In some examples, the DU functionality may provide limited control over the communications of the grandchild node, such as through indication of soft resources or restricted beams at the child nodes associated with the grandchild node. In some examples, the IAB node 110 implementing the DU functionality may be referred to as a scheduling node or scheduling component, and the IAB node 110 implementing the MT functionality may be referred to as a scheduled node or scheduled component.

[0048] In some examples, any network node 110 relaying communication may be referred to as a relay network node, a relay station, or simply a repeater. A repeater may receive communications from an upstream station (e.g., another network node 110 or UE 120) and transmit communications to a downstream station (e.g., UE 120 or another network node 110). In this case, the wireless communication network 100 may include or be referred to as a "multi-hop network." Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. Additionally or alternatively, UE 120 can be a relay station capable of relaying transmissions to or from other UE 120s, or can operate as such a relay station. UE 120 relaying communication can be referred to as a UE repeater or relay UE, etc.

[0049] In some examples, relay network node 110 may include an electromagnetic radiation reflection component that can be used to relay (e.g., reflect) a signal from a first other network node 110 to a second other network node 110 or UE 120. Such relay network node 110 may include, for example, a radio frequency reflection array configured to perform radio frequency reflection functionality. The electromagnetic radiation reflection array may be, for example, a reconfigurable smart surface (RIS) (which may also be referred to as a smart reflective surface (IRS)).

[0050] UE 120 may be physically distributed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. UE 120 may be, may include, an access terminal, another terminal, a mobile station, or a subscriber unit, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. UE 120 may be, or may include, a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband and / or smart jewelry (such as a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), an XR device, a vehicle component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device), a UE function of a network node, and / or any other suitable device or function that can communicate via a wireless medium, or may be coupled to them.

[0051] UE 120 may include or be included within a housing that houses components associated with UE 120, such as one or more processor components and / or one or more memory components. One or more processor components may be coupled to one or more memory components and / or other components. For example, processor components (e.g., one or more processors) and memory components (e.g., one or more memories) may be operatively coupled, communicatively coupled, electronically coupled, or electrically coupled to each other. In some examples, UE 120 includes one or more chips, system-on-a-chip (SoC), chipsets, packages, or devices that individually or collectively constitute or form part of a processing system. The processing system includes processor (or “processing”) circuitry in the form of one or more processors, microprocessors, processing units (such as central processing units (CPUs), graphics processing units (GPUs), or digital signal processors (DSPs)), processing blocks, application-specific integrated circuits (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), or other discrete gate or transistor logic components or circuits (all of which are generally referred to herein individually as “processors” or collectively as “processors” or “processor circuitry”). One or more of these processors may be individually or collectively configured to perform the various functions or operations described herein. The processing system may also include memory circuitry in the form of one or more memory devices, memory blocks, memory elements, or other discrete gate or transistor logic components or circuits, each of which may include tangible storage media such as random access memory (RAM) or read-only memory (ROM) or combinations thereof (all of which are generally referred to herein individually as "memory," or collectively as "memory" or "memory circuitry"). One or more of these memories may be coupled to one or more of the processors and may individually or collectively store processor-executable code that, when executed by one or more of the processors, configures one or more of the processors to perform the various functions or operations described herein. Additionally or alternatively, in some examples, one or more of the processors may be pre-configured to perform the various functions or operations described herein without requiring software configuration. The processing system may also include one or more modems (such as Wi-Fi (e.g., IEEE compliant) modems or cellular (e.g., 3GPP 4G LTE, 5G, or 6G compliant) modems), or be coupled to such modems. In some implementations, one or more processors of the processing system include or implement one or more modems in the modem.The processing system may also include, or be coupled to, multiple radio components (collectively, “radio components”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled to one or more of a plurality of antennas. In some embodiments, one or more processors of the processing system include or implement one or more of the radio components, RF chains, or transceivers.

[0052] Some UEs 120 may be considered Machine-Type Communication (MTC), or Evolved or Enhanced Machine-Type Communication (eMTC) UEs (or Further Enhanced eMTC (feMTC), or Enhanced feMTC (efeMTC), or further evolutions thereof, all of which may be simply referred to as "MTC"). An MTC UE may be, may include, or may be included in or coupled with the following: robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags. Some UEs 120 may be considered IoT devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. IoT UEs or NB-IoT devices may be, may include, or may be included in or coupled with the following: industrial machines, appliances, refrigerators, doorbell camera devices, home automation devices, and / or lighting fixtures, etc. Some UEs 120 may be considered customer premises equipment, which may include telecommunications equipment installed at a customer location (such as a home or office) to enable access to a service provider's network (such as being included in or communicating with wireless communication network 100).

[0053] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly with each other using sidelink communication (e.g., without communicating through a network node 110 acting as an intermediary). As an example, UE 120a can send data, control information, or other signaling directly to UE 120e as sidelink communication. This contrasts with, for example, UE 120a first sending data to network node 110 in UL communication, and then that network node sending data to UE 120e in DL communication. In various examples, UE 120 can communicate using peer-to-peer (P2P) communication protocols, device-to-device (D2D) communication protocols, vehicle-to-everything (V2X) communication protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or vehicle-to-pedestrian (V2P) protocols), and / or mesh network communication protocols. In some deployments and configurations, network node 110 may schedule and / or allocate resources for sidelink communication between UEs 120 in the wireless communication network 100. In some other deployments and configurations, UE 120 (instead of network node 110) may perform or cooperate with or negotiate with one or more other UEs to perform scheduling operations, resource selection operations, and / or other operations for sidelink communication.

[0054] Downlink and uplink resources may include time-domain resources (frames, subframes, time slots, and / or symbols), frequency-domain resources (bands, frequency carriers, subcarriers, resource blocks, and / or resource elements), and / or spatial-domain resources (specific transmission directions and / or beam parameters). Frequency-domain resources in some bands may be subdivided into bandwidth portions (BWPs). A BWP may be a contiguous block of frequency-domain resources allocated to one or more UEs 120 (e.g., a contiguous block of resource blocks). A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and downlink BWP may be the same BWP or different BWPs). BWPs may be dynamically configured and / or reconfigured (e.g., by sending DCI configuration to one or more UEs 120 via network node 110), meaning that BWPs may be adjusted in real-time (or near real-time) based on changing network conditions in the wireless communication network 100 and / or based on the specific requirements of one or more UEs 120. This allows for more efficient use of available frequency domain resources in the wireless communication network 100, as fewer frequency domain resources can be allocated to the BWP for UE 120 (which reduces the number of frequency domain resources that UE 120 needs to monitor), thus allowing more frequency domain resources to be distributed across multiple UE 120s. Therefore, the BWP can also assist in the implementation of such UE 120s by facilitating the configuration of smaller bandwidths for communications performed by lower-capacity UE 120s.

[0055] As indicated above, a BWP can be configured as a subset or part of the total or full component carrier bandwidth, and typically forms or covers a set of consecutive common resource blocks (CRBs) within the full component carrier bandwidth. In other words, within the carrier bandwidth, a BWP begins at a CRB and can span a set of consecutive CRBs. Each BWP can be associated with its own set of parameters (indicating subcarrier spacing (SCS) and cyclic prefix (CP)). UE 120 can be configured with up to four downlink BWPs and up to four uplink BWPs for each serving cell. To achieve reasonable UE battery consumption, under typical operation, only one downlink BWP and one uplink BWP are typically active at a given time on the active serving cell. The active BWP defines the operating bandwidth of UE 120 within the operating bandwidth of the serving cell, while all other BWPs configured on UE 120 are deactivated. On deactivated BWPs, UE 120 does not send or receive any communication.

[0056] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for specific geographic areas. In 3GPP, the term "cell" can refer to the coverage area of ​​network node 110 or to network node 110 itself, depending on the context in which the term is used. Network node 110 can support one or more (e.g., three) cells. In some examples, network node 110 can provide communication coverage for macro cells, pico cells, femto cells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femto cell (e.g., UE 120 in a Closed Subscriber Group (CSG)). A network node 110 used for a macro cell may be referred to as a macro network node. Network node 110 used for a picocell may be referred to as a pico network node. Network node 110 used for a femtocell may be referred to as a femto network node or a home network node. In some examples, the cell may not necessarily be stationary. For example, the geographical area of ​​the cell may move depending on the location of the associated mobile network node 110 (e.g., a train, satellite base station, drone, or NTN network node).

[0057] The wireless communication network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, piconet nodes, femtonet nodes, relay network nodes, aggregation network nodes, and / or decomposition network nodes, etc. Figure 1In the example shown, network node 110a can be a macro network node for macro cell 130a, network node 110b can be a pico network node for pico cell 130b, and network node 110c can be a femto network node for femto cell 130c. Compared to other types of network nodes 110, the various types of network nodes 110 typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0058] Network nodes 110 and UEs 120 of wireless communication network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, carriers, and / or channels according to frequency or wavelength. For example, devices of wireless communication network 100 can communicate using one or more operating frequency bands. In some aspects, multiple wireless networks 100 can be deployed in a given geographical area. Each wireless communication network 100 can support a specific RAT (which may also be referred to as an air interface) and can operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include 4G RATs, 5G / NRRATs, and / or 6G RATs, etc. In some examples, when multiple RATs are deployed in a given geographical area, each RAT in that geographical area can operate on a different frequency to avoid interference with each other.

[0059] Various operating frequency bands have been defined as frequency ranges designated FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Although a portion of FR1 is greater than 6 GHz, in some documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similarly, in some documents and articles, FR2 is often (interchangeably) referred to as the “millimeter wave” band, but this is different from the Very High Frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are often referred to as the mid-band frequencies, including FR3. Frequency bands falling within FR3 can inherit FR1 or FR2 characteristics, thereby effectively extending the characteristics of FR1 or FR2 into mid-band frequencies. Therefore, "below 6 GHz" (if used herein) can broadly refer to frequencies less than 6 GHz, within FR1, and / or included in mid-band frequencies. Similarly, the term "millimeter wave" (if used herein) can broadly refer to frequencies included in mid-band frequencies, within FR2, FR4, FR4-a, FR4-1, or FR5, and / or within the EHF band. Higher frequency bands can extend 5G NR operation, 6G operation, and / or other RATs above 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, wireless communication network 100 can implement dynamic spectrum sharing (DSS), where multiple RATs (e.g., 4G / LTE and 5G / NR) are implemented within a single frequency band using dynamic bandwidth allocation (e.g., based on user demand). It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1 and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0060] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive from a network node a configuration indicating a first measurement resource set and a second measurement resource set, wherein each of the first and second measurement resource sets includes one or more IMRs; measure, for each IMR included in the first or second measurement resource set, a CLI level associated with a downlink receive beam associated with one or more of the first or second TRPs; and send a report to the network node including information related to the CLI level associated with each of the one or more IMRs included in the first or second measurement resource set. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0061] In some aspects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may send to the UE a configuration indicating a first measurement resource set and a second measurement resource set, wherein the first and second measurement resource sets each include one or more IMRs; and receive from the UE a report including information relating to the CLI level associated with each IMR included in one or more IMRs in the first and second measurement resource sets for a first TRP or a second TRP. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0062] Figure 2 This is a diagram illustrating communication between an example network node 210 and an example UE 220 in a wireless network according to the present disclosure. Figure 2 Network node 210 can be a reference Figure 1 The example described is network node 110. Similarly, UE 220 can be a reference. Figure 1 An example of the described UE 120.

[0063] like Figure 2As shown, network node 210 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a to 232t, where t≥1), a set of antennas 234 (shown as 234a to 234v, where v≥1), a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, etc. In some configurations, one or a combination of antennas 234, modems 232, MIMO detectors 236, receive processors 238, transmit processors 214, and / or TX MIMO processors 216 may be included in the transceiver of network node 210. The transceiver may be under the control of and used by a processor (such as controller / processor 240), and in some respects, may perform aspects of the methods, procedures, and / or operations described herein in conjunction with processor-readable code stored in memory 242. In some respects, network node 210 may include one or more interfaces, communication components, and / or other components that facilitate communication with UE 220 or another network node.

[0064] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors. For example, references to “one / the processor” or “one / the controller / processor” (in the singular) should be understood as referring to a combination of… Figure 2 The processor described refers to any one or more processors (such as a single processor or a combination of multiple different processors). The reference to "one or more processors" should be understood as referring to a combination of... Figure 2 Any one or more processors described herein. For example, one or more processors of network node 210 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of UE 220 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280. As used herein, “processor,” “controller,” or “controller / processor” may refer to a general-purpose processor, DSP, ASIC, FPGA or other PLD, discrete gate or transistor logic unit, discrete hardware component, or any combination thereof. A general-purpose processor may be a microprocessor, or any commercially available processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors incorporating a DSP core, a system-on-a-chip (SoC), or any other such configuration).

[0065] In some aspects, a single processor can be described as capable of performing all operations performed by one or more processors. In some aspects, a first set of processors(one or more) of one or more processors can be described as capable of performing a first function performed by those processors, and a second set of processors(one or more) of one or more processors can be described as capable of performing a second function performed by those processors. The first set of processors and the second set of processors can be the same set of processors or can be different sets of processors. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as combined... Figure 2 The memory described. For example, a function described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0066] For downlink communication from network node 210 to UE 220, transmitting processor 214 may receive data (“downlink data”) intended for use by UE 220 (or a set of UEs including UE 220) from data source 212 (such as a data pipeline or data queue). In some examples, transmitting processor 214 may select one or more MCSs for UE 220 based on one or more Channel Quality Indicators (CQIs) received from UE 220. Network node 210 may process the data (e.g., including encoding the data) based on the MCS selected for UE 220 for transmission to UE 220 on the downlink, thereby generating data symbols. Transmitting processor 214 may process system information (e.g., semi-static resource partitioning information (SRPI)) and / or control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and / or control symbols. The transmitting processor 214 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS), or CSI reference signals (CSI-RS)) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

[0067] The TX MIMO processor 216 can perform space processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can output a set of symbol streams (e.g., TA set of output symbol streams is provided to modem 232. For example, each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 232. Each modem 232 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for orthogonal frequency division multiplexing (OFDM)) to obtain an output sample stream. Each modem 232 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a time-domain downlink signal. Modems 232a to 232t may transmit the set of downlink signals (e.g., via a set of corresponding antennas 234) together. T (One downlink signal).

[0068] Downlink signals may include DCI communication, MAC-CE communication, RRC communication, downlink reference signals, or another type of downlink communication. Downlink signals may be transmitted on the PDCCH, PDSCH, and / or on another downlink channel. Downlink signals may carry one or more transport blocks (TBs) of data. A TB may be a data unit transmitted via the air interface in the wireless communication network 100. A data stream (e.g., from data source 212) may be encoded into multiple TBs for transmission via the air interface. The number of TBs used to carry data associated with a particular data stream may be associated with a TB size shared by multiple TBs. The TB size may be based on the radio channel conditions of the air interface, the MCS used to encode the data, downlink resources allocated for transmitting data, and / or other parameters, or otherwise associated with them. Generally, a larger TB size allows for a larger amount of data to be transmitted in a single transmission, reducing signaling overhead. However, a larger TB size may be more prone to transmission and / or reception errors than a smaller TB size, but such errors can be mitigated by more robust error correction techniques.

[0069] For uplink communication from UE 220 to network node 210, the uplink signal from UE 220 may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected where applicable by MIMO detector 236 (e.g., receive (Rx) MIMO processor), and / or further processed by receive processor 238 to obtain decoded data and / or control information. Receive processor 238 may provide the decoded data to data sink 239 (which may be a data pipeline, data queue, and / or another type of data sink) and provide the decoded control information to processors such as controller / processor 240.

[0070] Network node 210 may use scheduler 246 to schedule one or more UEs 220 for downlink or uplink communication. In some aspects, scheduler 246 may use DCI to dynamically schedule DL transmissions to and / or UL transmissions from UE 220. In some examples, scheduler 246 may allocate repetitive time-domain and / or frequency-domain resources that UE 220 may use for transmission and / or reception of communication using RRC configuration (e.g., semi-static configuration), for example, to perform semi-persistent scheduling (SPS) or to configure configuration grant (CG) for UE 220.

[0071] One or more of the following may be included in the RF chain of network node 210: transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, and / or controller / processor 240. The RF chain may include filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs), and / or other devices for converting analog signals (such as those used for transmission or reception via an air interface) to digital signals (such as those used for processing by one or more processors of network node 210). In some aspects, the RF chain may be a transceiver of network node 210, or may be included in such a transceiver.

[0072] In some examples, network node 210 may use communication unit 244 to communicate with the core network and / or other network nodes. Communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, fiber optic, Common Public Radio Interface (CPRI), and / or wired or wireless backhaul, etc. Network node 210 may use communication unit 244 to send and / or receive data associated with UE 220, or to execute network control signaling, etc. Communication unit 244 may include transceivers and / or interfaces, such as network interfaces.

[0073] UE 220 may include a collection of antennas 252 (shown as antennas 252a to 252r, where r ≥ 1), a collection of modems 254 (shown as modems 254a to 254u, where u ≥ 1), a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, and / or a memory 282, etc. One or more components of UE 220 may be included in housing 284. In some aspects, one or a combination of antennas 252, modems 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266 may be included in a transceiver included in UE 220. The transceiver may be under the control of and used by a processor (such as controller / processor 280), and in some aspects, may perform aspects of the methods, processes, or operations described herein in conjunction with processor-readable code stored in memory 282. In some respects, UE 220 may include another interface, another communication component and / or another component that facilitates communication with network node 210 and / or another UE 220.

[0074] For downlink communication from network node 210 to UE 220, the set of antennas 252 can receive downlink communication or signals from network node 210, and can receive the set of downlink signals (e.g., R Each received signal is provided to a set of modems 254. For example, each received signal may be provided to a corresponding demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use the corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain an input sample. Each modem 254 may use the corresponding demodulator component to further demodulate or process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from the set of modems 254, may perform MIMO detection on the received symbols where applicable, and may provide the detected symbols. Receiver processor 258 may process (e.g., decode) the detected symbols, may provide the decoded data for UE 220 to data sink 260 (such as a data pipeline, data queue, and / or application executed on UE 220), and may provide the decoded control information and system information to controller / processor 280.

[0075] For uplink communication from UE 220 to network node 210, transmitting processor 264 may receive and process data (“uplink data”) from data source 262 (such as data pipelines, data queues, and / or applications running on UE 220) and control information from controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, receiving processor 258 and / or controller / processor 280 may determine one or more parameters related to the transmission of uplink communication for received signals (such as those received from network node 210 or another UE). One or more parameters may include a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, a CQI parameter, or a Transmit Power Control (TPC) parameter, etc. The control information may include indications of RSRP, RSSI, RSRQ, CQI, TPC, and / or another parameter. Control information can facilitate parameter selection and / or scheduling for UE 220 by network node 210.

[0076] Transmit processor 264 can generate reference symbols for one or more reference signals, such as uplink DMRS, uplink sounding reference signal (SRS), and / or another type of reference signal. Symbols from transmit processor 264 can be pre-decoded by TX MIMO processor 266 (where applicable) and further processed by an assembly of modems 254 (e.g., for DFT-s-OFDM or CP-OFDM). TX MIMO processor 266 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (where applicable) and can provide an output symbol stream set (e.g., ...) to the assembly of modems 254. R Each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 254. Each modem 254 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 254 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.

[0077] Modems 254a to 254r can transmit uplink signal sets (e.g., via a set of corresponding antennas 252) RUplink signals may include UCI communication, MAC-CE communication, RRC communication, or another type of uplink communication. Uplink signals may be transmitted on PUSCH, PUCCH, and / or another type of uplink channel. Uplink signals may carry one or more TBs of data. Sidelink data and control transmission (i.e., transmission directly between two or more UEs 220) may typically use techniques similar to those described for uplink data and control transmission, and may use sidelink-specific channels such as the Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), and / or Physical Sidelink Feedback Channel (PSFCH).

[0078] One or more antennas in the set of antennas 252 or the set of antennas 234 may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc., or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or with one or more transmitting or receiving components (such as...) Figure 2 An antenna module is a combination of one or more antenna elements coupled to one or more components. As used herein, "antenna" can mean one or more antennas, one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays. "Antenna panel" can mean a group of antennas (such as antenna elements) arranged in an array or panel that can facilitate beamforming by manipulating the parameters of that group of antennas. "Antenna module" can mean a circuit that includes one or more antennas, and may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.

[0079] In some examples, each antenna element of antenna 234 or antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. Antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements can allow signals with a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam) in various directions. For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half a wavelength, or another fraction of the wavelength between adjacent antenna elements to allow desired constructive and destructive interference modes of signals transmitted by individual antenna elements within that desired range.

[0080] The amplitude and / or phase of signals transmitted via antenna elements and / or sub-elements can be modulated and (e.g., by manipulating phase shifts, phase offsets, and / or amplitudes) shifted relative to each other to generate one or more beams; this is known as beamforming. The term "beam" can refer to the directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. The term "beam" can also generally refer to the direction associated with such directional signal transmission, the set of directional resources associated with the signal transmission (e.g., angle of arrival, horizontal direction, and / or vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal. In some implementations, antenna elements can be individually selected or deselected for the directional transmission of a signal (or multiple signals) by controlling the amplitude and / or phase of one or more corresponding amplifiers to form one or more beams. The shape of the beam (such as amplitude, width, and / or the presence of sidelobes) and / or the direction of the beam (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of multiple signals relative to each other.

[0081] Different UEs 220 or network nodes 110 may include different numbers of antenna elements. For example, UE 220 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or different numbers of antenna elements. As another example, network node 210 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or different numbers of antenna elements. Generally speaking, a larger number of antenna elements provides increased control over the parameters used for beamforming compared to a smaller number of antenna elements, while a smaller number of antenna elements may be less complex to implement and can use less power. Multiple antenna elements can support multi-layer transmission, in which the same time and frequency resources are used to utilize spatial multiplexing to transmit a first layer of communication (which may include a first data stream) and a second layer of communication (which may include a second data stream).

[0082] Network node 210 may provide UE 220 with a configuration of Transmission Configuration Indicator (TCI) states, which indicate or correspond to beams that UE 220 may use for, for example, receiving one or more communications via a physical channel. For example, network node 210 may (e.g., using DCI) indicate an active TCI state to UE 220, which UE 220 may use to generate a beam for receiving one or more communications via a physical channel. The beam indication may be, or may include, TCI state information elements, beam identifier (ID), spatial relation information, TCI state ID, closed-loop index, panel ID, TRP ID, and / or SRS set ID, etc. TCI state information elements (sometimes referred to herein as TCI state) may indicate specific information associated with the beam. For example, TCI state information elements may indicate a TCI state identifier (e.g., tci- StateID ), QCL type (e.g., qcl-Type1 , qcl-Type2 , qcl-TypeA , qcl-TypeB , qcl-TypeC or qcl- TypeD etc.), community signage (e.g., ServCellIndex ), bandwidth part identifier ( bwp-Id ) or reference signal identifier (such as CSI-RS identifier (e.g., NZP-CSI-RS-ResourceId or SSB-Index(etc.) Spatial relationship information can similarly indicate information associated with the uplink beam. Beam indication can be joint or separate DL / UL beam indication within a unified TCI framework. Within a unified TCI framework, the network can support common TCI state ID updates and activations, which can provide common QCL and / or common UL transmit spatial filters across a set of configured component carriers. This type of beam indication can be applied to in-band CA as well as joint DL / UL beam indication and separate DL / UL beam indication. A common TCI state ID can refer to a reference signal determined based on the TCI state indicated by the common TCI state ID, used to provide QCL type D indication and determine the UL transmit spatial filter across a set of configured CCs.

[0083] In some examples, the network may support L1-based beam indication using at least a UE-specific (unicast) DCI indication that can be selected from the active TCI state, either as a combined or separate DL / UL beam indication. In some examples, DCI formats 1_1 and / or 1_2 may be used for beam indication. Network node 210 may include a support mechanism for UE 220 to acknowledge successful decoding of the beam indication. For example, acknowledgment / negation of a PDSCH scheduled by a DCI carrying the beam indication may also be used as acknowledgment for the DCI.

[0084] Further efficiency improvements in throughput, signal strength, and / or other signal properties can be achieved through beam refinement. For example, network node 210 may be able to communicate with UE 220 using beams of various beamwidths. For instance, network node 210 may be configured to utilize a wider beam to communicate with UE 220 when UE 220 is in motion, as wider coverage increases the likelihood that UE 220 will remain within the coverage area of ​​network node 210 while moving. Conversely, when UE 220 is stationary, network node 210 uses a narrower beam to communicate with UE 220, as network node 210 can reliably focus coverage on UE 220, and the likelihood of UE 220 moving out of the coverage area of ​​network node 210 is low or minimal. In some examples, to select a specific beam for communicating with UE 220, network node 210 may transmit reference signals, such as synchronization signal blocks (SSBs) or CSI-RS, in a beam-sweeping manner on each of multiple beams. In some examples, the SSB can be transmitted on a wider beam, while the CSI-RS can be transmitted on a narrower beam. The UE 220 can measure the RSRP or signal-to-interference-plus-noise ratio (SINR) on each of the beams and send a beam measurement report (e.g., an L1 measurement report) to the network node 210 indicating the RSRP or SINR associated with each of one or more of the measured beams. The network node 210 can then select a specific beam for communicating with the UE 220 based on the L1 measurement report. In some other examples, when channel reciprocity exists between the uplink and downlink, the network node 210 can derive a specific beam for communicating with the UE 220 (e.g., on both the uplink and downlink) based on uplink measurements of one or more uplink reference signals (such as SRS) transmitted by the UE 220.

[0085] One enhancement for multi-beam operation at higher carrier frequencies is to facilitate efficient (e.g., low latency and low overhead) downlink and / or uplink beam management operations to support higher Layer 1 and / or Layer 2 (L1 / L2) centered inter-cell mobility. L1 and / or L2 signaling, referred to as “lower-layer” signaling, can be used to activate and / or deactivate candidate cells in the cell set configured for L1 / L2 mobility, and / or provide reference signals for measurement by UE 220, which can then select candidate beams as target beams for lower-layer handover operations. Therefore, one objective of L1 / L2 centered inter-cell mobility is to enable UEs to perform cell handovers via dynamic control signaling at lower layers (e.g., DCI for L1 signaling or MAC-CE for L2 signaling) instead of semi-static L3 RRC signaling, in order to reduce latency, lower overhead, and / or otherwise improve the efficiency of cell handovers.

[0086] In some examples, for UE 220, one antenna panel can be used for UL transmission and another for DL ​​reception. In some examples, full-duplex communication can be conditional on beam separation of the UL and DL beams at the respective antenna panels. Utilizing full-duplex communication can reduce latency, making it possible to receive DL signals in UL-only time slots, thus achieving latency savings. Furthermore, full-duplex communication can enhance spectral efficiency per cell or per UE 220 and enable more efficient resource utilization. Beam separation of the UL and DL beams helps limit or reduce self-interference that may occur during full-duplex communication. Separating the UL and DL beams on their respective antenna panels provides reliable full-duplex communication by minimizing or reducing self-interference.

[0087] Full-duplex UE 220 can perform a self-interference measurement (SIM) procedure to identify self-interference transmitted from full-duplex UE 220. Full-duplex network node 210 can also perform a SIM procedure to identify self-interference transmitted from full-duplex network node 210. UE 220 can provide a measurement report to network node 210 to indicate the results of the UE SIM. Network node 210 can select multiple beam pairs (referred to herein as "beam pairs") for use during full-duplex communication for UE 220 ("UE beam pair") and network node 210 ("network node beam pair"). Beam pairs typically include Rx beams and Tx beams, such as DL beams and UL beams for UE 220, and similarly, UL beams and DL beams for network node 210.

[0088] The controller / processor 240 of network node 110 and network node 210, and the controller / processor 280 of UE 120 and UE 220 or Figure 1or Figure 2 Any other component may implement one or more technologies or perform one or more operations associated with the CLI configuration under the CSI framework for supporting mTRP operations, as described in more detail elsewhere in this document. For example, the controller / processor 240 of network node 210, the controller / processor 280 of UE 220, Figure 2 Any other component that can execute or direct, for example Figure 8 The process 800 Figure 9 The operation of process 900 or other processes as described herein (alone or in combination with one or more other processors). Memory 242 may store data and program code of network node 110 or network node 210. Memory 282 may store data and program code of UE 120 or UE 220. In some examples, memory 242 or memory 282 may include a non-transitory computer-readable medium storing instruction sets (e.g., code or program code) for wireless communication. Memory 242 may include one or more memories, such as a single memory or multiple different memories (of the same type or different types). Memory 282 may include one or more memories, such as a single memory or multiple different memories (of the same type or different types). For example, the instruction set may be executed by one or more processors of network node 210 or UE 220 (e.g., directly, or after compilation, transformation, or interpretation). Figure 8 The process 800 Figure 9 The process 900 or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions, and / or interpret instructions, etc.

[0089] In some aspects, UE 220 includes components for receiving from network node 210 an indication of the configuration of a first measurement resource set and a second measurement resource set, wherein each of the first and second measurement resource sets includes one or more IMRs; components for measuring a CLI level associated with a downlink receive beam associated with one or more of the first or second TRPs for each IMR included in the first or second measurement resource set; and / or components for sending a report to network node 210 including information related to the CLI level associated with each of the one or more IMRs included in the first and second measurement resource sets. Components for UE 220 to perform the operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0090] In some aspects, network node 210 includes components for sending to UE 220 instructions on the configuration of a first measurement resource set and a second measurement resource set, wherein each of the first and second measurement resource sets includes one or more IMRs; and / or components for receiving reports from UE 220, the reports including information related to CLI levels associated with each IMR in one or more IMRs included in the first and second measurement resource sets for a first TRP or a second TRP. Components for network node 210 to perform the operations described herein may include, for example, one or more of the following: communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0091] Figure 3 These are illustrations of examples 300, 310, 320, and 330 of full-duplex communication in a wireless network according to this disclosure. As described herein, “full-duplex communication” generally refers to simultaneous uplink and downlink communication in a wireless network, which can be the capability of a UE, a network node, or another suitable device. For example, a UE operating in full-duplex mode may transmit uplink communication and receive downlink communication at the same time (e.g., in the same time slot or the same symbol), and / or a network node operating in full-duplex mode may receive uplink communication and transmit downlink communication at the same time. “Half-duplex communication” in a wireless network generally refers to unidirectional communication at a given time (e.g., downlink communication only or uplink communication only) (e.g., a device only transmits or only receives in a given time slot or a given symbol).

[0092] like Figure 3 Examples 300 and 310 illustrate examples of IBFD communication. In an IBFD communication scenario, the UE can send uplink communication to and receive downlink communication from a network node on the same time and frequency resources. As shown in Example 300, in the first example of IBFD, the time and frequency resources used for uplink communication can completely overlap with those used for downlink communication (e.g., all time and frequency resources allocated to uplink communication can also be used for downlink communication). As shown in Example 310, in the second example of IBFD, the time and frequency resources used for uplink communication can partially overlap with those used for downlink communication (e.g., some time and frequency resources are reserved only for uplink communication).

[0093] like Figure 3Further examples 320 and 330 illustrate examples of SBFD communication, which may also be referred to as "Subband Frequency Division Duplex (SBFDD)," "Flexible Duplex," or FDD in "(Unpaired Spectrum)." In an SBFD configuration, a UE can simultaneously send uplink communication to a network node and receive downlink communication from a network node on different frequency resources. For example, different frequency resources could be subbands of a band such as a TDD band. In such examples, the frequency resources used for downlink communication can be separated from the frequency resources used for uplink communication in the frequency domain by guard bands, for example, as shown in Example 320. The SBFD configuration may include both a downlink bandwidth portion and an uplink bandwidth portion that can be active simultaneously, wherein a guard band separates the downlink bandwidth portion and the uplink bandwidth portion (e.g., to prevent interference). Additionally or alternatively, as shown in Example 330, the SBFD configuration may include a first downlink bandwidth portion, a second downlink bandwidth portion, and an uplink bandwidth portion provided between the first and second downlink bandwidth portions, wherein a first guard band separates the uplink bandwidth portion from the first downlink bandwidth portion, and a second guard band separates the uplink bandwidth portion from the second downlink bandwidth portion.

[0094] Figure 4 These are illustrations of examples 400, 410, and 420 illustrating full-duplex deployment scenarios in which CLI and / or SI may occur according to this disclosure. Figure 4 As shown, Examples 400, 410, and 420 include one or more UEs communicating with one or more network nodes in a wireless network supporting full-duplex communication. Generally, as described herein, utilizing full-duplex communication modes can provide reduced latency by allowing downlink transmissions to occur in uplink-only time slots and / or by allowing uplink transmissions to occur in downlink-only time slots. Furthermore, by simultaneously utilizing time and frequency resources for downlink and uplink communication, full-duplex communication can improve spectral efficiency or throughput per cell or per UE, and / or achieve more efficient resource utilization. However, as described further in detail herein, full-duplex communication modes can be associated with dynamic interference conditions.

[0095] For example, such as Figure 4 As shown, Example 400 includes a first UE (shown as UE1) and a second UE (shown as UE2) communicating with a first network node (shown as NN1) operating in full-duplex mode, wherein the first UE and the second UE operate in half-duplex mode. For example, as Figure 4As shown, a first UE can send one or more uplink transmissions to a first network node, and a second UE can concurrently receive one or more downlink transmissions from the first network node. Therefore, in Example 400, the first network node operates in full-duplex mode, and the first and second UEs each operate in half-duplex mode. As shown in Example 400, various forms of interference can exist, which may degrade downlink reception performance at one or more UEs and / or uplink reception performance at the first network node operating in full-duplex mode. For example, as shown, the first network node may experience inter-cell CLIs caused by downlink transmissions from a second network node (shown as NN2) that may be located in an adjacent or nearby cell. Furthermore, as shown, uplink transmissions from the first UE to the first network node can cause intra-cell CLIs at the second UE (e.g., CLIs interfering with downlink reception at the second UE). Additionally, as shown, the first network node may experience self-interference, where downlink transmissions to the second UE interfere with reception of uplink transmissions from the first UE. For example, as described herein, self-interference can typically occur when the transmitted signal leaks into the receiving port and / or when objects in the surrounding environment reflect the transmitted signal back to the receiving port (e.g., causing clutter echo effects), thus interfering with the reception of the desired signal at the receiving port. Generally, the full-duplex mode used by the first network node in Example 400 can be SBFD mode, where the component carrier bandwidth is divided into non-overlapping uplink and downlink subbands.

[0096] like Figure 4 Further, as shown in Example 410, the first UE can communicate with the first network node in full-duplex mode. For example, in Example 410, the first UE can receive one or more downlink transmissions from the first network node, and the first UE can concurrently send one or more uplink transmissions to the first network node. Therefore, in Example 410, both the first network node and the first UE operate in full-duplex mode. Furthermore, as shown, the first network node can communicate with a second UE operating in half-duplex mode. Figure 4As shown, the first UE may experience self-interference, where uplink transmission to the first network node interferes with the reception of downlink transmissions from the first network node, and the first UE may cause cross-link interference at the second UE, where uplink transmission to the first network node interferes with the downlink reception at the second UE. Additionally, in Example 410, the first network node may experience inter-cell CLI caused by one or more downlink transmissions from the second network node interfering with the reception of uplink transmissions from the first UE, and the first network node may experience self-interference, where downlink transmissions to the first UE and / or the second UE interfere with the reception of uplink transmissions from the first UE. In Example 410, full-duplex communication can be performed in SBFD mode (where component carrier bandwidth is divided into non-overlapping uplink and downlink subbands) or in IBFD mode (where uplink and downlink resources are fully or partially overlapping).

[0097] like Figure 4 As further illustrated in Example 420, the first UE can communicate with both the first and second network nodes in full-duplex mode (e.g., multi-TRP mode). For example, in Example 420, the first UE can send one or more uplink transmissions to the first network node, and the first UE can concurrently receive one or more downlink transmissions from the second network node. Therefore, in Example 420, the first UE operates in full-duplex mode, and both the first and second network nodes operate in half-duplex mode. Figure 4 As shown, the first UE may experience self-interference, where uplink transmissions to the first network node interfere with the reception of downlink transmissions from the second network node. Furthermore, uplink transmissions by the first UE can cause inter-UE CLI at the second UE receiving downlink transmissions from the second network node. Additionally, as shown, downlink transmissions by the second network node can cause inter-cell CLI at the first network node interfering with the reception of uplink transmissions from the first UE. In Example 420, full-duplex communication can be performed in SBFD mode (where component carrier bandwidth is divided into non-overlapping uplink and downlink subbands) or in IBFD mode (where uplink and downlink resources are fully or partially overlapping).

[0098] Figure 5 These are illustrations of examples 500, 510, and 520 illustrating different duplex modes according to this disclosure. For example, as described further herein, Figure 5Examples 500 illustrate an FDD mode that can be used in paired spectrum, 510 an TDD mode that can be used in unpaired spectrum, and 520 an SBFD mode that can be used in unpaired spectrum. Generally, wireless communication standards and / or regulatory bodies may specify one or more duplex modes for the use of wireless spectrum. For example, 3GPP may specify how wireless spectrum is used for 5G or NR RATs and interfaces. As an example, specifications may indicate whether a frequency band is to be used as paired spectrum in FDD mode or as unpaired spectrum in TDD mode or another mode.

[0099] For example, as shown in Example 500, paired spectrum in FDD mode can use a first frequency region (or channel) for uplink communication and a second frequency region (or channel) for downlink communication. In these cases, the frequency regions or channels used for uplink and downlink communication do not overlap, have different center frequencies, and are sufficiently spaced to prevent interference between downlink and uplink communication. For example, paired spectrum in FDD mode can include uplink operating bands and downlink operating bands configured to use non-overlapping frequency regions separated by guard bands. Therefore, when operating in FDD mode in paired spectrum, a UE with full-duplex capability can perform concurrent transmit and receive operations using the separate operating bands allocated to downlink and uplink communication. For example, paired bands in NR include NR operating bands n1, n2, n3, n5, n7, n8, n12, n20, n25, and n28, as specified in 3GPP TS 38.101-1.

[0100] Alternatively, as shown in Example 510, unpaired spectrum in TDD mode allows downlink and uplink operation within a single frequency region (e.g., a single operating band). For example, when operating in TDD mode in unpaired spectrum, downlink and uplink communication can occur in the same frequency range. Some deployments may use TDD in unpaired bands, where some transmission time intervals (e.g., frames, slots, and / or symbols) are used solely for downlink communication, and other transmission time intervals are used solely for uplink communication. In such examples, depending on whether communication is performed in a downlink interval, an uplink interval, or a special interval (where downlink or uplink communication can be scheduled), essentially the entire bandwidth of the component carrier can be used for either downlink or uplink communication. Examples of unpaired bands include NR operating bands n40, n41, and n50, as specified in 3GPP TS 38.101-1. However, in some cases, using TDD in unpaired spectrum may be inefficient. For example, uplink transmit power may be limited, meaning the UE may not be able to transmit with sufficient power, thus failing to efficiently utilize the full bandwidth of the uplink time slot. This can be particularly problematic at the cell edges of larger cells. Furthermore, TDD can introduce latency compared to a full-duplex scheme that can perform both uplink and downlink communication within the same time interval, as TDD restricts the use of a given transmission time interval to either uplink or downlink communication only. Additionally, by restricting the use of a given transmission time interval to either uplink or downlink communication only, TDD can reduce spectral efficiency and / or throughput.

[0101] Therefore, as shown in Example 520, unpaired frequency bands can be configured in full-duplex mode to enable concurrent transmit and receive operations in unpaired spectrum (e.g., TDD bands). For example, in Figure 5 In Example 520, an SBFD mode is depicted, which may be referred to herein as full-duplex in frequency division multiplexing (FDM) mode to enable TDD and / or FDD operations in unpaired spectrum. For example, as Figure 5As shown, unpaired frequency bands configured in SBFD mode can associate one or more transmission time intervals with downlink-only communication (e.g., "D" time slot), one or more transmission time intervals with uplink-only communication (e.g., "U" time slot), and one or more transmission time intervals with both downlink and uplink communication (e.g., "D+U" time slot). Each transmission time interval can be associated with a control region, which is exemplified as a portion of a time interval with diagonal padding for uplink control (e.g., PUCCH) or darker shading padding for downlink control (e.g., PDCCH). Additionally or alternatively, each time interval can be associated with a data region, which is shown as a PDSCH for a downlink frequency region or a PUSCH for an uplink frequency region.

[0102] In some respects, unpaired frequency bands configured in SBFD mode may include one or more downlink-only time intervals, one or more uplink-only time intervals, and / or one or more full-duplex time intervals (e.g., frames, subframes, time slots, and / or symbols, etc.) associated with an FDD configuration. For example, as Figure 5 As shown, the FDD configuration associated with a full-duplex time interval can indicate one or more downlink frequency regions (or sub-bands) and one or more uplink frequency regions (or sub-bands) separated by guard bands. Therefore, the FDD configuration can divide unpaired frequency bands (e.g., one or more component carriers of an unpaired frequency band) into uplink frequency regions, downlink frequency regions, and / or other regions (e.g., guard bands). This allows a full-duplex UE to perform simultaneous transmission and reception operations during one or more time intervals divided into downlink and uplink sub-bands with guard band spacing, preventing self-interference from uplink transmission relative to downlink reception. For example, within a given full-duplex time interval, a half-duplex UE can transmit using an uplink frequency region or receive using a downlink frequency region (e.g., a first UE communicating using half-duplex can receive only in the lower downlink frequency region during the full-duplex time interval), and a full-duplex UE can transmit using an uplink frequency region and / or receive using a downlink frequency region (e.g., a second UE communicating using full-duplex can receive in a higher downlink frequency region simultaneously with transmission in the uplink frequency region during the full-duplex time interval). In some aspects, the FDD configuration can identify the bandwidth portion configuration corresponding to the uplink and downlink frequency regions. For example, the corresponding bandwidth portion can be configured for each uplink frequency region and each downlink frequency region.

[0103] Additionally or alternatively, full-duplex can be enabled in unpaired spectrum in IBFD mode, which may be referred to herein as full-duplex in spatial division multiplexing (SDM) mode. For example, in IBFD or SDM mode, uplink communication may occur on time and frequency resources that completely overlap with those allocated to downlink communication (e.g., all time and frequency resources available for uplink communication can also be used for downlink communication), or uplink communication may occur on time and frequency resources that partially overlap with those available for downlink communication (e.g., some time and frequency resources available for uplink communication can also be used for downlink communication, and some time and frequency resources available for uplink communication are uplink-only). Generally, in IBFD mode, full-duplex communication can depend on sufficient beam separation between the uplink and downlink beams (e.g., uplink transmission can come from one antenna panel and downlink reception can be in another antenna panel) to minimize self-interference that may occur when the transmitted signal leaks into the receiver port and / or when objects in the surrounding environment reflect the transmitted signal back to the receiver port (e.g., causing clutter echo effects).

[0104] Figures 6A to 6B These are illustrations of examples 600 and 650 that may occur in inter-cell CLI and intra-cell CLI in dynamic TDD and / or full-duplex deployment scenarios according to this disclosure. For example, refer to... Figure 6A Example 600 depicts dynamic TDD communication. As shown in Example 600, when dynamic TDD is implemented, neighboring cells (e.g., Figure 6A Cells 1 and 2 in the network can use different TDD configurations to communicate with the UEs served in the corresponding cells. This can result in uplink communication between the first UE (UE1) and the first network node (network node 1) and downlink communication between the second network node (network node 2) and the second UE (UE2) occurring in the same TTI. Concurrent uplink and downlink communication in different transmission directions (e.g., downlink to uplink) within the same TTI may interfere with each other, which can be referred to as CLI. Interference caused by the second UE's uplink communication transmission and by the first UE's downlink communication reception can be referred to as UE-to-UE CLI or inter-UE CLI. For example, as Figure 6AAs shown by reference numeral 610 in the illustrated dynamic TDD scenario, the transmission of uplink communication by UE1 in cell 1 in a symbol or time slot may interfere with the reception of downlink communication by UE2 in cell 2 in a symbol or time slot. This interference may be referred to as inter-cell UE-to-UE CLI or inter-cell UE CLI. Additionally or alternatively, as shown by reference numeral 620, the transmission of downlink communication by a second network node in cell 2 in a symbol or time slot may interfere with the reception of uplink communication by a second network node in cell 2 in a symbol or time slot. This interference may be referred to as inter-cell network node-to-network node CLI, inter-cell network node CLI, or gNB CLI.

[0105] refer to Figure 6BExample 650 illustrates examples of full-duplex communication, such as SBFD, fully overlapping IBFD, or partially overlapping IBFD. As indicated by reference numeral 660, in an FD scenario, a transmission of uplink communication by a first UE in a cell within an SBFD or IBFD time slot or symbol may interfere with the reception of downlink communication by a second UE in the same cell within the same SBFD or IBFD time slot or symbol. For example, a transmission of uplink communication by a first UE (UE1) in a first cell (cell 1) within an SBFD or IBFD time slot or symbol can interfere with the reception of downlink communication by a second UE (UE2) in cell 1 within the same SBFD or IBFD time slot or symbol. As another example, a transmission of uplink communication by a third UE (UE3) in a second cell (cell 2) within an SBFD or IBFD time slot or symbol may interfere with the reception of downlink communication by a fourth UE (UE4) in cell 2 within the same SBFD or IBFD time slot or symbol. This interference may be referred to as intra-cell UE-to-UE CLI or intra-cell inter-UE CLI. In an SBFD scenario, uplink communication transmission by a UE (e.g., UE1) in a cell (e.g., cell 1) on an uplink subband (SB) in an SBFD symbol or time slot may interfere with downlink communication reception by another UE (e.g., UE2) in the same cell on a downlink SB in an SBFD symbol or time slot. This interference may be referred to as inter-SB intra-cell UE-to-UE CLI or inter-SB intra-cell UE-to-CLI. Additionally or alternatively, as indicated by reference numeral 670, in an FD scenario, uplink communication transmission by a first UE in a first cell on an SBFD or IBFD symbol or time slot may interfere with downlink communication reception by a second UE in a second cell on an SBFD or IBFD symbol or time slot. This interference may be referred to as inter-cell UE-to-CLI. In an SBFD scenario, uplink communication transmission by a first UE in a first cell on an uplink SB in an SBFD symbol or time slot may interfere with downlink communication reception by a second UE in a second cell on a downlink SB in an SBFD symbol. This type of interference can be referred to as inter-SB inter-cell UE CLI. Additionally or alternatively, as indicated by reference numeral 680, the transmission of downlink communication by a first network node in a first cell in an SBFD or IBFD symbol or time slot may interfere with the reception of uplink communication by a second network node in a second cell on an uplink SB in an SBFD or IBFD symbol or time slot. This type of interference can be referred to as inter-SB inter-cell network node (or gNB inter-) CLI.

[0106] Figure 7 This is a diagram illustrating an example 700 associated with a CLI configuration under the CSI framework for supporting mTRP operations, according to this disclosure. Figure 7As shown, Example 700 includes communication between a UE (such as UE 120 or 220) and a network node (such as network node 110 or 210). In some aspects, the UE and the network node may be included in a wireless network (such as wireless network 100). The network node and the UE may communicate via a wireless access link (which may include an uplink and a downlink). Furthermore, as... Figure 7 As shown, network nodes and UEs can communicate in an mTRP scenario, where the network node includes, controls, or otherwise associates with multiple TRPs. For example, Figure 7 An example of an mTRP scenario is illustrated, in which network nodes include, control, or otherwise associate with a first TRP (shown as TRP1) and a second TRP (shown as TRP2) capable of concurrently transmitting downlink communication to a UE. Furthermore, one or more TRPs may communicate in dynamic TDD or full-duplex mode, which could lead to inter-UE CLI caused by concurrent uplink transmissions to the second (intruding) UE and downlink transmissions to the first (suppressed) UE.

[0107] Therefore, the various aspects described herein generally relate to CLI configuration provided under a CSI framework to support mTRP operation in a manner that enables the affected UE to measure and report inter-UE CLI for each downlink received beam, each downlink received beam corresponding to a TRP communicating with the UE in SBFD mode, IBFD mode, dynamic TDD mode, and / or another suitable mode that may be subject to intra-cell inter-UE CLI and / or inter-cell inter-UE CLI. For example, as described herein, the CLI configuration for supporting mTRP operation can be extended according to a CSI framework that enables mTRP operation or can be defined in other ways, wherein network nodes can configure the UE with multiple sets of resources associated with multiple TRPs for downlink channel and interference measurement (e.g., using...). groupBasedBeamReporting-r17 parameter).

[0108] For example, when a network node has two TRPs (such as...) Figure 7 In the scenario of the first TRP and the second TRP shown, when configuring the UE for mTRP operation, the network node can configure the NZP CSI-RS resource set that the UE can use for channel measurement. In this case, the NZP CSI-RS resource set may include a number of resources that can be divided into separate resource groups for each TRP. K s For example, the first resource group may include a first number of resources for performing channel measurements relative to the first TRP. K 1. The second resource group may include a second number of resources for performing channel measurements relative to the second TRP.K 2. Furthermore, the first resource group and the second resource group may each include one or more resources (e.g., such that...). K 1≥1 and K 2≥1), and the NZP CSI-RS resource set may include up to 8 resources (e.g., making 2≥1), K 1+ K 2= K s And 2≤ K s ≤8). Therefore, when the UE is configured with the NZP CSI-RS resource set, the UE can be configured to send a report to the network node indicating the optimal channel measurement associated with it. N A resource pair, wherein each resource pair includes a first resource (e.g., a first CMR) from a first resource group and a second resource (e.g., a second CMR) from a second resource group, wherein For example, a report provided by the UE can indicate the optimal channel measurement based on the SINR measurement associated with the CMR in the corresponding resource group. N This resource pair allows network nodes to select the optimal beam pair associated with the two TRPs for mTRP operation.

[0109] Therefore, in some aspects, network nodes can be adapted to the measurement configuration associated with the CSI framework to provide UEs with configurations for implementing inter-UE CLI measurements and reporting. For example, Figure 7A first scenario 710 is depicted, in which a network node includes or controls a first TRP and a second TRP configured for mTRP operation, and a first UE (shown as the affected UE) is configured to receive concurrent downlink transmissions from the first TRP using a first CMR (shown as DL-CMR1) corresponding to a first downlink beam and from the second TRP using a second CMR (shown as DL-CMR2) corresponding to a second downlink beam. Furthermore, in this first scenario, the first TRP is configured to communicate in full-duplex mode (such as SBFD or IBFD), wherein the second UE (shown as the intruding UE) can be configured to concurrently perform uplink transmissions to the first TRP with the downlink transmissions to the first (affected) UE. In this first scenario, the uplink transmissions performed by the intruding UE may cause inter-UE CLIs relative to the received downlink transmissions from the first TRP, and may also cause inter-UE CLIs relative to the received downlink transmissions from the second TRP. However, since the disturbed UE receives data from the first TRP via the first downlink receiving beam and from the second TRP via the second downlink receiving beam and transmits data via the downlink, the UE-to-UE CLI caused by the intruding UE can vary across the first CMR corresponding to the first downlink receiving beam and the second CMR corresponding to the second downlink receiving beam.

[0110] Therefore, in the first scenario 710, where the disturbed UE uses different downlink receive beams to receive concurrent downlink transmissions from the first TRP and the second TRP, the network node can configure the disturbed UE to measure and report inter-UE CLI for each downlink receive beam, each downlink receive beam corresponding to each of multiple TRPs in other duplex scenarios such as SBFD, IBFD, dynamic TDD, or potentially intra-cell inter-UE CLI and / or inter-cell inter-UE CLI. For example, in some aspects, the network node can configure a CLI measurement resource set per TRP (e.g., two CLI measurement resource sets in the first scenario 710 where two TRPs exist), where each CLI measurement resource set is configured as the IMR that the disturbed UE wants to use to measure the CLI level of each CMR associated with the corresponding TRP. For example, in some aspects, a network node may configure a first CLI measurement resource set, which may include or correspond to a first IMR set, which includes one or more IMRs, and the affected UE may use the one or more IMRs in the first IMR set to measure the inter-UE CLI level relative to each CMR configured for the first TRP. In similar aspects, a network node may configure a second CLI measurement resource set, which may include or correspond to a second IMR set, which includes one or more IMRs, and the affected UE may use the one or more IMRs in the second IMR set to measure the inter-UE CLI level relative to each CMR configured for the second TRP. For example, as... Figure 7 As shown, the first IMR set may include a first IMR (shown as IMR1-CLI), which the affected UE can measure to determine the inter-UE CLI level relative to the CMR corresponding to the first downlink receive beam associated with the first TRP, and the second IMR set may include a second IMR (shown as IMR2-CLI), which the affected UE can measure to determine the inter-UE CLI level relative to the CMR corresponding to the second downlink receive beam associated with the second TRP. In this way, the affected UE can use different IMR sets to measure the inter-UE CLI level caused by the downlink receive of the intruding UE relative to each TRP.

[0111] Additionally or alternatively, in the second scenario 720, the affected UE may use a wider beam to communicate with different TRPs (e.g., different TRPs using downlink beams with shared space Rx parameters or QCL type D relationships). In the second scenario 720, the affected UE may use a relatively wide downlink receive beam to concurrently receive downlink transmissions from different TRPs. For example, as Figure 7As shown, the affected UE can use a relatively wide downlink receive beam to concurrently receive a first downlink transmission from a first TRP and a second downlink transmission from a second TRP. In this case, to improve reception performance, the affected UE can be configured to receive the first downlink transmission from the first TRP using a first panel (e.g., a first antenna panel or a first antenna set) and receive the second downlink transmission from the second TRP using a second panel (e.g., a second antenna panel or a second antenna set). In this case, the network node can configure an IMR that the affected UE can use to measure the inter-UE CLI level of the UE using the same downlink receive beam on one or more panels for receiving downlink transmissions from different TRPs. For example, as Figure 7 As shown, the IMR (shown as IMR1-CLI) can be configured to measure the inter-UE CLI level relative to the CMR associated with the downlink receive beam of the first TRP, and to measure the inter-UE CLI level relative to the CMR associated with the downlink receive beam of the second TRP.

[0112] Therefore, as Figure 7 As further illustrated, configuring the disturbed UE to measure and report inter-UE CLI may include a first operation 730, wherein the network node transmits and the (disturbed) UE receives a measurement configuration indicating one or more CMRs and associated IMRs for measuring the CLI level of each CMR. For example, in some aspects, the measurement configuration provided by the network node may indicate a resource set per TRP, wherein each resource set may include one or more CMRs and one or more CLI IMRs. For example, in an mTRP configuration with two TRPs, the measurement configuration may indicate a first resource set including one or more CMRs associated with a first TRP, wherein one or more CMRs in the first resource set are associated with one or more CLI IMRs associated with one or more intruding UEs, one or more transmit beams of one or more intruding UEs, and / or one or more receive beams of the disturbed UE. Furthermore, in an mTRP scenario with two TRPs, the measurement configuration may indicate a second resource set including one or more CMRs associated with the second TRP, wherein one or more CMRs in the second resource set are associated with one or more CLI IMRs associated with one or more intruding UEs, one or more transmit beams of one or more intruding UEs and / or one or more receive beams of the harassed UE.

[0113] In some respects, the mapping between CMRs and CLI IMRs in each resource set can be configurable, depending on the use case associated with the mTRP operation enabled by the network node. For example, as described herein, each resource set may include a number of CMRs. K1and a number of CLI IMR L ,in L Can be less than, equal to or greater than K1 Furthermore, the mapping between the number of CMRs and the number of CLI IMRs can vary across resource sets associated with different TRPs. For example, a first resource set associated with a first TRP may include a number of CMRs equal to the number of CLI IMRs, and a second resource set associated with a second TRP may include a number of CMRs less than or greater than the number of CLI IMRs. For example, in a first mTRP use case, there may be one or more downlink receive beams where there is no inter-UE CLI or where CLI measurement is not required in other respects. In this case, the network node can configure a resource set where the number of CLI IMRs is less than the number of CMRs (e.g., L < K1 Additionally or alternatively, in the second mTRP use case, the set of resources associated with the TRP may include multiple CMRs associated with different (relatively narrow) transmit beams on the TRP side, but the various transmit beams share QCL type D relationships relative to the wider downlink receive beams on the UE side. In this use case, the multiple CMRs associated with the TRP may share CLI IMRs for inter-UE CLI measurements, such that the number of CLI IMRs is less than the number of CMRs (e.g., L < K1 Additionally or alternatively, in the third mTRP use case, a single CMR may be associated with inter-UE CLI measurements caused by multiple intruding UEs or multiple transmit beams associated with intruding UEs. In this use case, the network node may configure multiple IMRs for the CMR to enable separate measurements of the CLI level for each intruding UE or each transmit beam of the intruding UE, such that the number of CLI IMRs exceeds the number of CMRs (e.g., L > K1 ).

[0114] Therefore, in the second operation 740, the UE can measure the inter-UE CLI level associated with each CLI IMR configured by the network node (e.g., relative to each CMR in the same resource set). In the third operation 750, the UE can send a report indicating or otherwise capturing the inter-UE CLI level associated with each CLI IMR. For example, as described above, a UE configured to communicate with multiple TRPs can be configured to report. NOptimal resource pairs, wherein each resource pair includes a first resource corresponding to a first CMR or downlink receive beam associated with a first TRP and a second resource corresponding to a second CMR or downlink receive beam associated with a second TRP. In some aspects, CSI metrics such as CQI values ​​or L1-SINR values ​​can be used to implicitly capture the inter-UE CLI level associated with each IMR. In such cases, the UE may consider the CLI level of each IMR when calculating or otherwise determining the CQI value, L1-SINR value, or other CSI metrics used for selection. N Each resource pair is reported to network nodes for beam management and / or beam selection. For example, in some aspects, the CSI metric for a resource pair may be based on or otherwise associated with a joint CLI level measured for multiple TRPs, or the CSI metric for a resource pair may be based on or otherwise associated with a CLI level measured individually for each TRP (e.g., in the case of incoherent joint transmission, where each TRP can be configured with an independent pre-decoder).

[0115] Additionally or alternatively, the report provided by the UE may independently indicate the inter-UE CLI level as a CLI metric. For example, in some aspects, the report may include a CLI-RSRP measurement, a CLI-RSSI measurement, a CLI-SINR measurement, or another suitable CLI metric to indicate the inter-UE CLI level for one or more IMR and / or resource pairs. For example, in some aspects, the UE may report the number of CLI resources associated with the highest CLI per TRP, the number of CLI resources associated with the lowest CLI per TRP, the number of CLI resources associated with the highest CLI among multiple TRPs, and / or the number of CLI resources associated with the lowest CLI among multiple TRPs. In some aspects, the network node may configure the UE to report the inter-UE CLI level as a CLI metric when interference changes faster than channel conditions. This allows the network node to configure the UE to report the CLI level independently at a more frequent periodicity than CSI metrics (e.g., CQI values) used for mTRP operation.

[0116] Furthermore, in some aspects, network nodes can configure the UE to report multiple assumptions about the CLI level associated with mTRP operations using a single report configuration. For example, in some aspects, the network node can configure a QCL type D relationship with reference to a first SSB corresponding to a first resource group or resource set for a first TRP and a second SSB corresponding to a second resource group or resource set for a second TRP. In such cases, the UE can then report multiple CLI assumptions in a single report. For example, in some aspects, the UE can report multiple assumptions including: a first CLI metric measured using the QCL type D relationship of the first SSB for a single TRP (sTRP) operation with a first TRP, wherein the first CLI metric corresponds to a first downlink receive beam; a second CLI metric measured using the QCL type D relationship of the second SSB for an sTRP operation with a second TRP, wherein the second CLI metric corresponds to a second downlink receive beam; and a third CLI metric measured using the QCL type D relationship of the first and second SSBs for an mTRP operation with both a first and a second TRP. Furthermore, the third CLI metric for mTRP operation can correspond to a pair of downlink receive beams, which may be the same as or different from the beams selected for sTRP operation (e.g., because interference conditions may change during periodic beam management and / or beam selection, and the UE can identify the corresponding downlink receive beams). In this way, the network node can determine whether the UE can use different downlink receive beams to support sTRP and / or mTRP operations within tolerable CLI constraints.

[0117] Figure 8 This is a flowchart illustrating an example procedure 800, performed, for example, at a UE or a device of a UE, to support CLI measurements and reporting for mTRP operations, according to this disclosure. Example procedure 800 is an example in which a device or UE (e.g., UE 120 or UE 220) performs operations associated with CLI configurations for supporting mTRP under the CSI framework.

[0118] like Figure 8 As shown, in some aspects, process 800 may include: receiving from a network node a configuration indicating a first measurement resource set and a second measurement resource set, wherein the first measurement resource set and the second measurement resource set each include one or more IMRs (block 810).

Figure 10 The depicted communication manager 140 or receiving component 1002 can receive configurations from a network node indicating a first measurement resource set and a second measurement resource set, wherein each of the first and second measurement resource sets includes one or more IMRs, as described above.

[0119] like Figure 8 Further shown, in some aspects, process 800 may include: for each IMR measurement included in the first measurement resource set or the second measurement resource set, the CLI level associated with the downlink receive beam associated with one or more of the first TRP or the second TRP (block 820). For example, the UE (such as by using...) Figure 10 The depicted communication manager 140 or CLI measurement component 1008 can measure the CLI level associated with the downlink receive beam of one or more of the first TRP or the second TRP for each IMR included in the first measurement resource set or the second measurement resource set, as described above.

[0120] like Figure 8 Further shown, in some aspects, process 800 may include: sending a report to a network node that includes information related to the CLI level associated with each IMR included in one or more IMRs in a first measurement resource set and a second measurement resource set (box 830). For example, a UE (such as by using...) Figure 10 The depicted communication manager 140 or transmitting component 1004 can send a report to a network node, which includes information related to the CLI level associated with each IMR included in one or more IMRs in a first measurement resource set and a second measurement resource set, as described above.

[0140] Figure 9 This is a flowchart illustrating an example process 900 for supporting configured CLI measurements and reporting, performed, for example, at a network node or a device of a network node, according to this disclosure. Example process 900 is an example in which a device or network node (e.g., network node 110) performs operations associated with CLI configuration for supporting mTRP under the CSI framework.

[0143] Process 900 may include additional aspects, such as any single aspect or any combination of aspects described in one or more other processes described below or in conjunction with other parts of this document.

[0144] In a first additional aspect, the first measurement resource set and the second measurement resource set each include a first IMR set for measuring CLI levels associated with one or more downlink receive beams associated with the first TRP and a second IMR set for measuring CLI levels associated with one or more downlink receive beams associated with the second TRP.
