[0001] The present Application for Patent claims priority to U.S. Patent Application No. 18 / 623,475 by IBRAHIM et al., entitled “IMPLICIT CROSS-LINK INTERFERENCE REPORTING IN SUB-BAND FULL DUPLEX,” filed April 1, 2024. assigned to the assignee hereof, and expressly incorporated by reference herein.FIELD OF TECHNOLOGY

[0002] The following relates to wireless communications, including implicit crosslink interference reporting in sub-band full duplex.BACKGROUND

[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g.. time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE).SUMMARY

[0004] The described techniques relate to improved methods, systems, devices, and apparatuses that support implicit cross-link interference reporting in sub-band full duplex.

[0029] In some wireless communications systems, a user equipment (UE) may be configured to communicate with a network entity in a full duplex mode. In some examples, network entity may communicate with multiple UEs in a full duplex mode. Uplink and downlink transmissions betw een the network entity and the multiple UEs (e.g., or between the UE and multiple network entities) may cause cross-link interference (CLI) at the UEs. For example, uplink transmission at a first UE may cause CLI at a second UE receiving a downlink transmission. The CLI may reduce communication efficiency and reliability at the interfering UEs.

[0030] According to techniques described herein, the UE may implicitly report information about CLI measurements in a channel state information (CSI) report. For example, the UE may receive control signaling indicating a set of channel measurement resources (CMRs) and a set of interference measurement resources (IMRs). The UE may perform one or more CIS measurements via the set of CMRs, and the UE may perform multiple CLI measurements via the set of IMRs. The UE may indicate one or more of the CLI resources with the least interference via the CSI report. Additionally, or alternatively, the UE may derive CSI metrics based on the CLI measurements. The UE may transmit the CSI report to the network entity. The network entity may schedule the multiple UEs based on the CSI reports such that UEs with high interference are not schedule for full duplex communication at the same time. The scheduling may provide for improved communications efficiency and reliability.

[0031] Aspects of the disclosure are initially described in the context of wireless communications systems. Additional aspects of the disclosure are described in the context of a CSI report configuration structure and process flow; Aspects of the disclosure are further illustrated by and described herein with reference to apparatusdiagrams, system diagrams, and flowcharts that relate to implicit CLI reporting in subband full duplex.

[0032] FIG. 1 shows an example of a wireless communications system 100 that supports implicit CLI reporting in sub-band full duplex in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105), one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE- Advanced (LTE- A) network, an LTE- A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0033] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link(s) 125 (e.g., a radio frequency (RF) access link). For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link(s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs).

[0034] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105), as shown in FIG. 1.

[0035] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 1 15, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity' 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.

[0036] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link(s) 120 (e.g.. in accordance with an SI, N2, N3, or other interface protocol). In some examples, network entities 105 may communicate with one another via backhaul communication link(s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly betw een network entities 105) or indirectly (e.g., via the core network 130). In some examples, netw ork entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol), or any combination thereof. The backhaul communication link(s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g.. an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link), among otherexamples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.

[0037] One or more of the network entities 105 or network equipment described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home NodeB, a Home eNodeB, or other suitable terminology). In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140).

[0038] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture), which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities 105), such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (e.g.. a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, a network entity 105 may include one or more of a central unit (CU), such as a CU 160, a distributed unit (DU), such as a DU 165, a radio unit (RU), such as an RU 170, a RAN Intelligent Controller (RIC), such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC). a Non-Real Time RIC (Non-RT RIC)), a Service Management and Orchestration (SMO) system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmission reception point (TRP). One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

[0039] The split of functionality between a CU 160, a DU 1 5, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g.. Radio Resource Control (RRC). service data adaptation protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 1 0 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs). or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (LI) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU 170). In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170). A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g.. Fl, F 1-c, Fl-u), and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.

[0040] In some wireless communications systems (e.g., the wireless communications system 100), infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130). In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node(s) 104) may be partially controlled by each other. The IAB node(s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station). The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node(s) 104) via supported access and backhaul links (e.g., backhaul communication link(s) 120). IAB node(s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g.. scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node(s) 104 used for access via the DU 165 of the IAB node(s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT)). In some examples, the IAB node(s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node(s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream). In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node(s) 104 or components of the IAB node(s) 104) may be configured to operate according to the techniques described herein.

[0041] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support test as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175. an SMO system 180).

[0042] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some othersuitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (loT) device, an Internet of Everything (loE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.

[0043] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.

[0044] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication hnk(s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link(s) 125. For example, a carrier used for the communication link(s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP)) that is operated according to one or more PHY layer channels for a given RAT (e g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may cany' acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity ) of a network entity 105. For example, the terms “transmitting,” “receiving,” or “communicating,” when referring to a network entity 105, may refer to any portion of anetwork entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105).

[0045] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam), and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.

[0046] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts= l / ^ fmax■seconds, for which fmaxmay represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0047] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclicprefix prepended to each symbol period). In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g.. Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

[0048] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g.. in bursts of shortened TTIs (sTTIs)).

[0049] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE).

[0050] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105). In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105). The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.

[0051] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC). The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

[0052] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity' 105 (e.g., a base station 140, an RU 170), which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherw ise unable to or not configured to receive transmissions from a network entity 105. In some examples,groups of the UEs 1 15 communicating via D2D communications may support a one-to- many (1:M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.

[0053] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW). or a user plane function (UPF)). The control plane entity' may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g.. base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS), or a Packet-Switched Streaming Service.

[0054] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longerwaves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0055] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA). Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0056] A network entity 105 (e.g.. a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated wi th a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 1 15. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.

[0057] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas.Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g.. the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), for which multiple spatial layers are transmitted to multiple devices.

[0058] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity' 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g.. with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation).

[0059] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g.. antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity' 105 multiple times along different directions. For example, the network entity' 105 may transmit a signal according to different beamforming weight sets associated with different directions oftransmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.

[0060] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., a network entity 105 or a UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as another network entity 105 or UE 115). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 1 15 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal qualify.

[0061] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115). The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a CSI reference signal (CSI-RS)), which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multipanel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described herein with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170), a UE 1 15 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device).

[0062] A receiving device (e.g., a UE 1 15) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105), such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g.. different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as ‘‘listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to- noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0063] In some cases, the UE 115 may transmit a CSI report to a network entity 105. The CSI report may be associated with a timing requirement. The timing requirements for CSI processing to may ensure (e.g., guarantee) that the UE 115 has enough time to generate CSI report. In some cases, the CSI report may be associated with an ultra-low latency timing requirement. The ultra-low latency may be based on some special cases (e.g., as defined in CSI computation delay requirement 1). In some cases, there may be multiple latency classes (e.g., as defined in CSI computation delay requirement 2). The multiple latency classes may include a low-latency class (e.g., Zl), a high-latency class (e.g., Z2), and a latency for beam-reporting (e g., Z3). A quantity of symbols or an amount of latency (e.g., for CSI processing, beam delays) may depend on reported UE capability.

[0064] In some cases, the CSI report may be transmitted via a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). The CSIreport structure for CSI reports may include a first and second part (e.g., CST parti and CSI part2). For PUCCH The mapping order of CSI fields in the CSI report may be based on the CSI report being associated with a wideband or a sub-band. For PUSCH, the mapping order of the second part may be based on the CSI report being associated with a wideband or a sub-band. In some cases, the first part of the CSI report (e.g., CSI part 1) may include one or more CSI fields in a single report or as a first part of a two- part CSI report. The CSI fields (e.g., for a wideband CSI part 1) may be indicated by a format indicator for wideband PMI and wideband CQI, or as a report quantity’, among other examples. Similarly, a mapping of an order of CSI part 2 for wideband or subband PMI may be configured. The first part of the CSI report or the second part of the CSI report may include different mappings or CSI fields based on the CSI report being transmitted on PUSCH or PUCCH. In some cases, different PUCCH formats may have different maximum payload sizes. For example, a UE 115 may not be expected to report CSI with a total quantity of uplink control information (UCI) bits and cyclic redundancy check (CRC) bits larger than a threshold (e.g., 115 bits) when configured with some PUCCH formats (e.g., PUCCH format 4).

[0065] According to techniques described herein, the UE 115 may implicitly include information about CLI measurements in a CSI report. For example, the UE 115 may receive control signaling indicating a set of CMRs and a set of IMRs. The UE 115 may perform one or more CIS measurements via the set of CMRs, and the UE 115 may perform multiple CLI measurements via the set of IMRs. The UE 115 may indicate one or more of the CLI resources with the least interference via the CSI report. Additionally, or alternatively, the UE 115 may derive CSI metrics based on the CLI measurements. The UE 115 may transmit the CSI report to the network entity'. The network entity may schedule the multiple UEs 115 based on the CSI reports such that UEs 115 with high interference are not schedule for full duplex communication at the same time. The scheduling may provide for improved communications efficiency and reliability.

[0066] FIG. 2 shows an example of a wireless communications system 200 that supports implicit CLI reporting in sub-band full duplex in accordance with one or more aspects of the present disclosure. In some examples, wireless communications system 200 may implement aspects of wireless communications system 100. For example, a UE 115-a, a UE 115-b. and a UE 115-c may represent an example of a UE. such as the UEs1 15 described herein with reference to FIG. 1 . The network entity 105-a may represent an example of a network entity7, such as the network entity 105 described herein with reference to FIG. 1. The UE 115-a may signal a CSI report 210 to the network entity 105-a. The CSI report 210 may include one or more CSI metrics 225 (e.g., a CSI metric 225-a and a CSI metric 225-b).

[0067] In some wireless communications systems, the UEs 115 (e g., the UE 115-a, the UE 115-b, and the UE 115-c) may communicate with the network entity 105-a via full duplex communication. In some cases, the UEs 115 may communicate with the network entity 105-a via in-band full duplex (IBFD). The network entity 105-a or the UEs 115 may transmit and receive on the same time and frequency resource. That is, the downlink and uplink resources may share the same IBFD time or frequency resource (e.g., the downlink and uplink resources may fully or partially overlap). For example, the UE 115-b may transmit uplink communication 215 to the network entity 105-a and the network entity 105-a may transmit downlink communication 220 to the UE 115-c via the same time and frequency resource. In some cases, the uplink communication resources and the downlink communications resources may overlap in accordance with communication resources 230. That is, the uplink communication resources and the downlink communication resources may at least partially overlap (e.g., as illustrated in FIG. 2).

[0068] In some cases, the UEs 1 15 may communicate with the network entity 105-a via sub-band frequency division duplex (FDD) (e.g., flexible duplex or sub-band full duplex (SBFD). The network entity 105-a or the UEs 115 may transmit and receive at the same time but on the different frequency resource. For example, the downlink resources may be separated from uplink resources in frequency domain. In other words, the downlink resources may not overlap with the uplink resources in the frequency domain. In some examples, the downlink resources and the uplink resources within the same time resource may be separated by a guard band.

[0069] The full duplex operations may generate CLI between the UEs 115 or the network entity 105-a and another network entity 105. For example, the network entity 105-a may simultaneously transmit downlink communications 220 to the UE 115-c and receive uplink communications 215 from the UE 115-b in a full duplex mode. In some examples, the UE 115-amay simultaneously transmit uplink communication 215 to thenetwork entity 105-a, and receive downlink signaling from the network entity 105-a or from another network entity 105 in a full duplex mode. In some examples, full duplex communications may result in interference (e.g., CLI). For example, the UE 115-b may transmit uplink communication 215. and the network entity 105-a may transmit downlink communication 220 to the UE 115-c. The transmitted uplink communication 215 may interfere with a downlink communication 220 at the UE 115-c. That is, the UE 115-b may generate CLI at the UE 115-c.

[0070] In some cases, the netw ork entity 105-a may transmit a CSI report configuration 205 to the UE 115-a. The CSI report configuration may be associated with multiple measurement resources (e.g., CMRs or IMRs). For example, the CSI report configuration may include a non-zero power (NZP) CSI-RS resource configuration for channel measurement. The NZP CSI-RS resource configuration may include one or more NZP CMR sets. Each NZP CMR resource set may include multiple NZP CMR resources, or a single NZP CMR resource. The CSI report configuration 205 may include a zero power (ZP) CSI-RS resource configuration for interference measurement (e.g., CSI interference measurement (CSI-IM)). The CSI-IM resource configuration may include one or more CSI-IM resource sets. Each CSI-IM resource set may include multiple CSI-IM resources. The CSI-IM resources may be used by the UEs 115 to measure interference from other cells. Each NZP CMR resource may correspond to a CSI-IM resource (e.g., the NZP CMR resources may have one-to-one mapping to the CSI-IM resources). In some cases, the CSI report configuration 205 may include a NZP CSI-RS resource configuration for interference measurement. The NZP CSI-RS resource configuration may include one or more NZP IMR sets. Each NZP IMR resource set may include multiple IMR. The IMR may be used for detecting spatial domain multiplexing interference. That is, the IMR may be used by the UE 115-a to measure interference caused by a downlink transmission to another UE 115 (e.g., the UE 115-c). For example, if the network entity 105-a transmit downlink communication 220 to the UE 115-a and the UE 1 15-c, there may be some leakage (e.g., interference) between the transmissions. Each IMR may correspond to one or more CSI-IM resource (e.g., the CSI-IM may have a one-to-many mapping to the IMR). Each NZP CMR resource may be associated with every IMR.

[0071] In some cases, the CST report configuration 205 may include a codebook configuration. The code book configuration may include the codebook type (e.g., typel- Singl ePanel, type 1 -MultiPanel, or type2) and a rank indicator (RI) restriction.

[0072] In some cases, the CSI report configuration 205 may include report configuration type (e.g., periodic, semi-persistent, or aperiodic). In some cases. CSI report configurations 205 associated with periodic or semi-persistent configuration types may include one NZP CMR resource set, one CSI-IM resource set, or one NZP IMR set based on the configuration type. In some cases. CSI report triggering (e.g., configured by CSI report configurations 205) associated with aperiodic configuration ty pes may select one set of the one or more NZP CMR resource sets, one set of the one or more CSI-IM resource sets, or one set of the one or more NZP IMR sets. In some cases, a single resource set within a resource setting may be used for measurement for a CSI report 210. In some examples, only a single resource set within a resource setting may be used for some CSI reports. In some examples. Periodic or semi-persistent CSI reports may be configured to include only one set of measurement resources (e g., One CMR resource set). In some examples, for an aperiodic CSI report, an aperiodic CSI report trigger may select one resource set (e.g., one CMR resource set) to be used.

[0073] The UE 115-a may perform CLI reporting based on performing a set of CLI measurements via the set of IMRs. The UE 115-a may use a CSI framework as for CLI reporting and may use a separate measurement resource for CLI (e.g., IMRs). The UE 115-a may use layer one signaling to indicate information about the set of CLI measurements. The layer one signaling may capture the impact of inter-UE CLI. In some cases, the UE 115-a may perform implicit CLI reporting. CLI impact may be captured in reported CSI quantity or metrics (e.g., channel quality’ indicator (CQI) and layer one-signal to interference plus noise ratio (Ll-SINR)). That is, the CSI metrics may be derived based on CSI measurements and based on the set of CLI measurements.

[0074] In some cases, the UE 115-a may perform explicit CLI reporting. For example, the UE 115-a may measure the CLI via an IMR. and the UE 115-a may report explicit CLI quantities (e.g., received signal strength indicator (RSSI) or reference signal received power (RSRP)) included in the report. The UE 115-a may report the CLI quantities via a new reportQuantity defined in the CSI report configuration 205. In some cases, the explicit CLI quantities may be included in a CLI report (e.g., reportQuantity =SRS-RSRP or CLI-RSSI). In some cases, the CLI quantities may be included in a CSI plus CLI report (e.g., reportQuantity = cri-CQI-RI-CLI_RSSI). The CSI report configuration 205 may include CLI metrics to one or more existing reportQunatities. The CSI report 210 including the CLI metrics may use a CSI report payload design.

[0075] For a scheduler at the network entity 105-a to minimize the impact of inter- UE CLI, proper UE-pairing may be used (e.g., may be relied on) for scheduling downlink or uplink in SBFD slots. That is, UEs 115 with low CLI can be scheduled simultaneously in an SBFD slot. For example, the UE 115-a and the UE 115-c may be schedule in the same SBFD slot based on a low CLI associated with the UEs 115. The UE 1 15-b and the UE 115-c may not be scheduled in the same SBFD slot based on a high CLI associated with the UEs 115.

[0076] To get accurate and timely CLI measurements, LI measurement, and reporting may be used (e.g., relied upon). Additionality, the UE 115-a may perform CLI measurement in multiple resources to characterize CLI from different aggressor UEs 115 (e.g., UEs 115 generating CLI at the UE 115-a) or to characterize CLI in different spatial directions (e.g., quasi co-located spatial receive parameters (QCL-D) in frequency range two (FR2)).

[0077] According to techniques described herein, the UE 115-a may perform multiple CLI measurements (e.g., to capture CLI from multiple UEs or multiple QCL- D) for implicit CLI reporting where CSI metrics 225 (CQI or RI) are derived based on measured CLI. For example, the UE 115-a may be instructed by the CSI report configuration 205 to perform implicit CLI reporting via the CSI report 210. The UE 115-a may perform one or more channel measurements based on receiving a CSI-RS from the network entity 105-a. The UE 115-a may perform multiple CLI measurements. The CLI measurements may measure CLI from one or more UEs 115 (e g., the UE 115-b and the UE 115-c). The UE 115-a may determine one or more CSI metrics 225 (e.g., the CSI metric 225-a and the CSI metric 225-b) based on the one or more channel measurements and the multiple CLI measurements. The UE 115-a may report the one or more CSI metrics 225 to the network entity 105-a via the CSI report 210. Implicit reporting of CLI (e.g., as captured via multiple CLI measurements) may be implicitly indicated via CSI reporting where reported CSI metrics are derived (e.g., for a given CRMs) based at least in part on the multiple CLI measurements.

[0078] FIG. 3 shows an example of a CST report configuration structure 300 that supports implicit CLI reporting in SBFD in accordance with one or more aspects of the present disclosure. In some examples, CSI report configuration structure 300 may implement aspects of, or be implemented by aspects of, the wireless communications system 100 or the wireless communications system 200. For example, the CSI report configuration structure 300 may be signaled by a UE 115 to a network entity 105 via a CSI report configuration, as described herein with reference to FIG. 2. The UE 115 and the network entity 105 may be examples of corresponding devices described herein with reference to FIGs. 1 and 2. In some cases, a network entity 105 may transmit a CSI report configuration 305 to a UE 115. The UE may transmit a CSI report to the network entity 105 in accordance with the CSI report configuration 305.

[0079] The CSI report configuration 305 may be configured to include a CMR configuration 310, as described herein with reference to FIG. 2. The CMR configuration 310 may include one or more CS1-RS sets 315. A CS1-RS set 315 may include multiple CSI-RS resources 320. According to techniques described herein, the CSI report configuration 305 may include CLI IMR configuration 325. The CLI IMR configuration may include CLI resource set 330. The CLI resource set 330 may include CLI resources (e.g., CLI resource 335). Each CSI-RS resource 320 may be mapped to every CLI resource (e.g., as illustrated in FIG. 3). That is, the CSI-RS resources 320 may have a one-to-many mapping to the CLI resources 335 (e.g., one CMR resource will be linked to M CLI measurement resources, where M is a quantity' of the CLI resources 335).

[0080] For example, if the CLI resource set 330 includes M CLI resources 335 and the CSI-RS set 315 includes one CSI-RS resource 320, the UE 115 may perform one channel measurement (e.g., via the one CSI-RS resource 320) and M interference measurements (e.g., via the M CLI resources 335). The UE 115 may determine the CSI metrics based on the one channel measurement and update the CSI metrics based on the M interference measurements. In some cases, the UE 115 may report a subset of the CLI measurements. If the CSI-RS set 315 includes more than one CSI-RS resource 320, the UE 115 may update the CSI metrics associated with each CSI-RS resource based on the M interference measurements. By reporting the CSI metrics associated with the CSI- RS resource 320 and based on the CLI measurements, the UE 115-a may also implicitly report the CLI measurements.

[0081] In some cases, the CST report may be linked to a single CST-RS resource 320 (e.g., a single CMR CSI-RS resource) (e.g., which may be indicated in the control signaling that configures the CSI report). That is, the CSI-RS set 315 may include a single CSI-RS resource 320. For CSI reports linked with single NZP-CSI-RS for channel measurement (e.g., a single CSI-RS resource 320), the bit-width of CRI field in the CSI report may be zero (e.g., in a CSI report with reportQuantity = CRI-xxxx). The CRI field may be used to indicated which CSI-RS resource 320 of the CSI-RS set 315 corresponds to the CSI metrics reported in the CSI report. However, if the CSI-RS set 315 includes only a single CSI-RS resource 320, then the value in the bit- width of CRI field may be available to indicate a CLI resource 335 on which the CSI metrics are based.

[0082] The UE 115 may be configured with implicit CLI reporting (e.g., by configuration or implicitly based on linkage to CLI resource settings). The UE 115 may report an indication of a CLI resource 335 with least interference. That is, the UE 115-a may determine a CLI resource 335 with a least interference based on the CLI measurements (e.g., across all of the M CLI resources 335) and the UE 115-a may indicate the CLI resource 335 having the least interference (e.g., the best or lowest CLI measurement) in the CSI report. In some cases, the CSI metrics (e.g., CQI or RI) in the CSI reports may be derived based on the CLI measurement associated with the least interference.

[0083] In some cases, the CSI report may include a report quantity explicitly indicating an IMR index used in the CSI computations. The network entity 105 may request the IMR index via the CSI report configuration. For example, the CSI metrics may be based on a CLI measurement associated with an IMR corresponding to the IMR index (e.g., cri-RI-CQI — > reportQuantity=cri-CLIri-RI-CQI, where CLIri takes value in {0,.,M-l} and M is the quantity of CLI resources 335 in the CLI resource set 330). The network entity 105 may determine the CLI resource 335 corresponding to the CSI metrics based on the IMR index.

[0084] In some cases, the CSI report may implicitly report the CLI measurements via another (e.g., repurposed) field in the CSI report. For example, the CSI report may reuse the CRI field (e.g., the CSI report may not define a new field) to indicate a CLI resource with a least amount of interference. The CRI field may be interpreted as a CLIresource index when the CSI report includes one CMR (e.g., one CSI-RS resource 320). The CRI field may be set to zero or may remain unused based on the CSI report including one CMR. The bit-width of the field may be equal to ceil(log2(M)), where M is the quantity of CLI resources 335 in the CLI resource set 330.

[0085] In some cases, the CSI report may be linked to multiple CMR resources (e.g., CSI-RS resources 320). That is, the CSI-RS set 315 may include multiple CSI-RS resources 320, and the CRI field may be used to indicate which of the CSI-RS resources 320 are used (e.g., have the best CSI metric values) for the CSI report. In some cases, the CSI report configuration 305 may define an additional field (e.g., an additional field in reportQuantity, reportQuantity=cri-CLIri-RI-CQI-PMI) to indicate a best CLI resource 335 (e.g., a CLI resource 335 associated with least interference). The CSI report may include an increased payload size (e.g., an additional payload size with additional ceil(log2(M)) bits). The indication of the best CLI resource 335 may indicate the CLI resource 335 based on which the CSI metrics (e.g.. corresponding to the CSI- RS resource 320 indicated by the CRI field) are derived.

[0086] In some cases, the CSI report may be transmitted via a PUSCH. The additional field may be included in a second part of the CSI report (e.g., the additional field may be added to CSI-part2). For cri-CLIri-RI-CQI, the report may not be a single part based on CLIri being included in the second part of the CSI report (e.g., CSl-part2).

[0087] In some cases, the CSI report may be transmitted via PUCCH (e.g., CSI reporting including implicit CLI reporting may be supported via PUCCH if one or more conditions are satisfied or in one or more scenarios). In some examples, the UE 115 may transmit the CSI report via PUCCH in the case of semi-persistent CSI reporting via PUCCH format 2, 3. or 4. In some examples, the UE 115 may transmit the CSI report via PUCCH in the case of CSI reporting including a single transport block (TB) CSI (e.g., the CSI report may not be transmitted via PUCCH if the CSI report includes more than a threshold quantity of TBs). The CSI report may include the single TB instead of an additional TB including CQI fields (e.g., for wideband CQI). The second part of the CSI report (e.g., CSI-part2) may include the CLI fields (e.g., indicating which CLI resource 335 corresponds to the CSI-RS resource 320 reported in the CSI report). The cases in which PUCCH CSI reporting is supported may ensure that the CSI report may not exceed a threshold payload size on PUCCH.

[0088] In some cases, the UE 1 15 may report more than one CST metrics considering a subset of CLI resources 335 (e.g., top L CSI corresponding to L CLI resources 335) with a least amount of interference. The UE 115 may report the subset of CLI resources 335 via a payload structure that supports reporting of multiple CLI resources 335. The payload structure may accommodate the L-l additional CSI metrics. The payload may be based on the reporting structure on a PUSCH or PUCCH. For example, the pay load structure may satisfy constraints on the payload size as PUCCH payload size is limited (e.g., PUCCH format 2 may support a limited payload size). PUSCH payload design may be more flexible compared to PUCCH (e.g.. PUSCH may support larger payload sizes). Fields for PUSCH CSI reporting may be defined in CSI- part2. In some cases, the payload may be based on report structures for different reportQuantity.

[0089] In some cases, the UE 115 may transmit the CSI report associated with more than one CLI resources 335 (e.g., L > 1) via PUSCH based on the large overhead compared to a CSI report associated with one CLI resource 335 (e g., L=l). In other words, the payload structure may allow for reporting on PUSCH given the large overhead. The CSI report may be transmitted via the PUSCH (e.g., a CSI-part2 for CSI via PUSCH). where fields indicating the CLI resources 335 based on which the CSI metrics were derived may be included in the payload structure. For example, the UE 115 may report three CLI resources 335 (e.g., L=3). The UE 115 may report a first CLI resource 335 via a first part of the CSI report, and the UE 115-a may report a second and third CLI resource 335 via a second part of the CSI report (e.g., CSI-part2). The first CLI resource 335 may be report via a new field in the first part of the CSI report or via the CRI field.

[0090] In some cases, the UE 115 may transmit the CSI report associated with more than one CLI resources 335 (e.g., L > 1) via PUCCH (e.g., PUCCH format 3 or 4) based on some conditions (e.g., Limit L <= X, where X is a threshold quantify of CLI resources 335 or wideband CSI reporting based on the already large overhead for sub band CSI). In other words, the payload structure may allow for reporting on PUCCH format 3 or 4 under some conditions. In some cases, the UE 115 may transmit the CSI report via PUSCH or PUCCH based on a quantify of CLI resources 335. For example, a threshold quantify of CLI resources 335 may be two. The UE 115 may transmit CSIreports with two or less CLT resources 335 via PUCCH, and the UE 115 may transmit CSI reports with more than two CLI resources 335 via PUSCH. In some examples, the CSI report may be transmitted via the PUCCH for wideband CSI reporting.

[0091] The UE 115 may support various processing times corresponding to the CSI report, processing capabilities for CSI reporting, or the like. For example, the UE 115 may determine a CSI processing unit (e.g., processing resources supporting CSI processing) threshold (e.g., requirement) at the UE 115, or timing threshold (e.g., a timing requirements expected by the network entity 105, based on Z or Z’ as described herein with reference to FIG. 1) based on the CSI reportQuantity and a quantity’ of CMRs associated with the CSI report. The multiple CLI resources 335 (e.g., CLI measurement resources) associated with the CSI report may introduce additional processing overhead at the UE 115. For example, each additional CMR or CLI resource 335 associated with the UE 115 may use additional processing time at the UE 115. In some examples, the network entity may not classify CSI reports with more than one CLI resource 335 (e.g., M > 1) as ultra-low latency even if all other ultra-low latency conditions are satisfied (e.g., a single CSI with wideband frequency-granularity’ and to at most four CSI-RS ports in a single resource without a CRI report and where codebookType is set to ‘typel-Singl ePanel' or where reportQuantity is set to ‘cri-RI- CQE) based on the quantity of CLI resources 335 configured for the CSI report.

[0092] In some cases, the timing for processing and transmitting (e.g., Zl / ZU, ZUZT , Z3 / Z3') associated with the CSI report, as described herein with reference to FIG. 1, may be relied upon by one or more devices, but additional timing offsets or delays (e.g., relaxations) may be implemented for CSI reporting with implicit CLI in the case of multiple CLI measurements as described herein. In some cases, the timing thresholds may include a relaxation time (e.g., Zi_new= Zi_old + X, where X is a relaxation time, and a function of L). For example, the relaxation time may be based on the quantity’ of CLI resources 335 in the subset of CLI resources 335. For instance, a network entity may schedule a CSI report at a timing offset plus a relaxation time X, and the UE 1 15 may not be expected to transmit the CSI report until after the timing offset plus the relaxation time X. In some cases, for single-TRP (sTRP) CSI reports (e.g., sTRP reports) associated with K CMRs, the CPU occupancy may follow one or more rules for CPU occupancy (e.g.. O cpu = K). In some cases, for sTRP reportsassociated with K CMRs, the CPU occupancy may introduce some extra term (e.g., O cpu = K + X, where X is a function of L). For example, the extra term may be based on the quantity of CLI resources 335 in the subset of CLI resources 335 (e.g.. L). In such examples, the sTRP reporting may be defined or allocated according to a base or default calculation of CSI processing unites plus an extension function (e.g., X) defining the additional CSI processing unites utilized by the UE 115 for CSI reporting with implicit CLI reporting, as described herein.

[0093] FIG. 4 shows an example of a process flow 400 that supports implicit CLI reporting in SBFD in accordance with one or more aspects of the present disclosure. In some examples, process flow 400 may implement aspects of, or be implemented by aspects of, the wireless communications system 100, wireless communications system 200, or the CSI report configuration structure 300. For example, the process flow 400 may include a UE 115-d and a network entity 105-b which may be examples of corresponding devices described herein with reference to FIGs. 1-3.

[0094] In some cases, at 405, the UE 115-d may transmit capability information indicating a computational capability for processing the CSI report, the computational capability based on a quantity of the set of CMRs, a second quantity of the set of IMRs, or both. Receiving first control signaling may be based on the computational capability.

The first CLI measurement may correspond to a smallest amount of measured CLI of the multiple of CLI measurements.

[0102] In some cases, the UE 115-d may include, in a CSI-RS resource indicator field of the first CSI report, an index value indicating a first IMR of the multiple IMRs that corresponds to a first CLI measurement, of the plurality of CLI measurements, from which the one or more CSI metrics are derived. The first CLI measurement may correspond to a smallest amount of measured CLI of the plurality of CLI measurements.

[0103] In some cases, the UE 115-d may include, in a set of IMR index fields in the first CSI report, a set of IMR index values indicating a first subset of IMRs of the multiple IMRs that corresponds to a subset of CLI measurements, of the multiple CLI measurements, from which the one or more CSI metrics are derived.

Any functions or operations described herein as being capable of being performed by a memory may be performed by multiple memories that, individually or collectively, are capable of performing the described functions or operations.

[0187] As used herein, including in the claims, “or’" as used in a list of items (e.g., a list of items prefaced by a phrase such as "at least one of’ or "‘one or more of’) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i. e. , A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on.”

[0188] As used herein, including in the claims, the article “a” before a noun is open- ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a.” “at least one,” “one or more,” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components,” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components.” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components”subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components.”

[0189] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure), ascertaining, and the like. Also, “determining” can include receiving (e g., receiving information), accessing (e.g., accessing data stored in memory), and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.

[0190] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.

[0191] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration” and not “preferred” or “advantageous over other examples.” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.

[0192] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs describedherein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
