[0025] For the purpose of describing the innovative aspects of the present disclosure, the following description relates to some specific implementations. However, those of ordinary skill in the art will readily recognize that the teachings herein can be applied in many different ways. The described specific implementations can be implemented in any device, system, or network capable of transmitting and receiving radio frequency (RF) signals according to any one of the Institute of Electrical and Electronics Engineers (IEEE) 16.11 standards or any one of the following: IEEE 802.11 standards, Standards, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Global System for Mobile Communications (GSM), GSM or General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio (TETRA), Wideband-CDMA (W-CDMA), Evolution-Data Optimized (EV-DO), 1xEV-DO, EV-DO Rev A, EV-DO Rev B, High-Speed Packet Access (HSPA), High-Speed Downlink Packet Access (HSDPA), High-Speed Uplink Packet Access (HSUPA), Evolved High-Speed Packet Access (HSPA+), Long-Term Evolution (LTE), AMPS or other known signals for communication within a wireless, cellular, or Internet of Things (IoT) network (such as a system utilizing third-generation (3G) technology, fourth-generation (4G) technology, fifth-generation (5G), or sixth-generation (6G) technology or other specific implementation technologies thereof).

[0026] In some systems, one or more wireless communication devices may support full-duplex communication, according to which such devices may transmit and receive simultaneously. Devices with full-duplex capabilities may employ various types of full-duplex communication, including sub-band full-duplex (SBFD) communication. According to SBFD communication, a device may transmit via a first set of one or more sub-bands and receive via a second set of one or more sub-bands, where the first set of sub-bands and the second set of sub-bands may not overlap in frequency. In some deployments, a full-duplex network entity may employ SBFD to communicate with two or more user equipments (UEs) simultaneously, and in such deployments, if a second UE transmits using frequencies similar to those used by a first UE, the first UE may experience inter-UE cross-link interference (CLI) from the nearby second UE. In some scenarios, a network entity may configure the first UE and the second UE to use the same or similar uplink sub-bands (and potentially one or more same or similar downlink sub-bands) to facilitate network-side SBFD operation, which may increase the likelihood of inter-UE CLI between the first UE and the second UE. In such scenarios, the first UE may experience CLI from the second UE at least in the uplink sub-band, which may adversely affect the receiver dynamic range or the performance of the receiver automatic gain control (AGC). In some systems, the UE and the network entity may lack a mutually understood set of mechanisms or rules according to which the UE may measure inter-UE CLI in the uplink sub-band in a system that supports network-side SBFD operation.

[0027] In some embodiments, the first UE and the network entity may support one or more signaling-based or configuration-based mechanisms according to which the first UE may measure CLI from the second UE in one or more uplink sub-bands or one or more downlink sub-bands or a combination thereof during an SBFD symbol. Thus, in some scenarios, the first UE may obtain both inter-sub-band CLI measurements (in at least one downlink sub-band) and intra-sub-band CLI measurements (in at least one uplink sub-band) based on measuring CLI reference signals transmitted from the second UE. In some aspects, the network entity may use an SBFD symbol during which the first UE will measure CLI for downlink communication to the first UE, and the first UE may have the ability to perform data communication associated with the network entity while measuring CLI reference signals transmitted from the second UE. Depending on the capabilities of the first UE, the first UE may receive a downlink signal (from the network entity in at least one downlink sub-band) and measure CLI reference signals (from the second UE in at least one uplink sub-band), or may alternatively receive the downlink signal or measure the CLI reference signals (and discard the other).

[0028] In some specific implementations, the first UE and the network entity may support a first priority sorting rule, and the first UE may select, identify, detect, or otherwise determine whether to prioritize downlink signals or CLI measurements according to the first priority sorting rule. Additionally or alternatively, the first UE and the network entity may support a second priority sorting rule, according to which the first UE and the network entity may expect or schedule uplink communication from the first UE during the SBFD symbol when the first UE is to measure the CLI. For example, if the first UE is scheduled to transmit an uplink signal during the SBFD symbol, the first UE may select, identify, detect, or otherwise determine whether to prioritize the uplink signal or the CLI measurement according to the second priority sorting rule. The first UE may use inter-subband CLI measurements (if obtained via the SBFD symbol) to measure inter-subband leakage, and may use intra-subband CLI measurements (if obtained via the SBFD symbol) to adjust the receiver dynamic range or the receiver AGC or both.

[0029] Specific implementations of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages. For example, according to a signaling-based or configuration-based mechanism that supports the first UE to more accurately obtain intra-subband CLI measurements without causing network ambiguity, according to which the first UE may measure the CLI from the second UE during the SBFD symbol in one or more uplink subbands or one or more downlink subbands or a combination thereof according to the capabilities of the first UE and potential scheduling conflicts. In other words, the first UE and the network entity may support a mutual or identical understanding (via signaling or one or more configurations) of the capabilities of the first UE and one or more priority sorting rules that the first UE may adopt, and may utilize such mutual or identical understanding to support better synchronization. This better synchronization may refer to how the first UE and the network entity may align regarding which signaling the first UE prioritizes during the SBFD symbol, or be associated with how the first UE and the network entity may align regarding which signaling the first UE prioritizes during the SBFD symbol, during which the first UE is configured to or otherwise attempts to perform CLI measurements. Additionally, according to obtaining intra-subband CLI measurements, the first UE may adjust the receiver dynamic range or the receiver AGC, which may increase the likelihood of successful communication to or from the first UE.

[0030] In addition, such signaling-based or configuration-based mechanisms can facilitate better adoption of full-duplex operation. According to such signaling-based or configuration-based mechanisms, a first UE can measure CLI from a second UE during SBFD symbols in one or more uplink subbands or one or more downlink subbands or a combination thereof, which can provide additional benefits to the adopting system. For example, full-duplex operation can support a longer uplink duty cycle, which can achieve latency reduction and greater uplink coverage. For example, according to full-duplex operation, a UE can receive a downlink signal in an "uplink-only" time slot, which can achieve or otherwise facilitate latency savings. In addition, full-duplex operation can increase system capacity, resource utilization, and spectral efficiency, and enable flexible and dynamic uplink or downlink resource adaptation according to uplink or downlink traffic in a robust (e.g., reliable) manner. For example, full-duplex operation can provide solutions for some dynamic time division duplex (TDD) challenges. Thereby, among other devices that can communicate with the first UE, the first UE can experience higher reliability, high data rates, and greater spectral efficiency, as well as lower latency and lower power consumption (by performing or receiving fewer retransmissions), among other benefits.

[0031] Figure 1 An example wireless communication system 100 that supports CLI measurement in SBFD operation is shown. The wireless communication system 100 can include one or more network entities 105, one or more UEs 115, and a core network 130. In some specific implementations, the wireless communication system 100 can be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other system and radio technologies (including future system and radio technologies not explicitly mentioned herein).

[0032] The network entities 105 can be dispersed throughout a geographic area to form the wireless communication system 100 and can include devices in different forms or with different capabilities. In various examples, the network entities 105 can be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other names. In some specific implementations, the network entities 105 and the UEs 115 can communicate wirelessly via one or more communication links 125 (such as radio frequency (RF) access links). For example, the network entities 105 can support a coverage area 110 (such as a geographic coverage area) over which the UEs 115 and the network entities 105 can establish one or more communication links 125. The coverage area 110 can be an example of a geographic area within which the network entities 105 and the UEs 115 can support signal communication according to one or more radio access technologies (RATs).

[0033] UE 115 can be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. The UE 115 can be a device in different forms or with different capabilities. Some example UEs 115 are illustrated in Figure 1 herein. The UE 115 described herein may be capable of supporting communication with various types of devices (such as other UEs 115 or network entities 105 as shown in Figure 1 ).

[0034] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) can be a network entity 105 (such as any network entity described herein), a UE 115 (such as any UE described herein), a network controller, a device, an equipment, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node can be a UE 115. As another example, the node can be a network entity 105. As yet another example, a first node can be configured to communicate with a second node or a third node. In one aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a UE 115. In another aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a network entity 105. In other aspects of this example, the first node, the second node, and the third node can be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc. can include the disclosure of UE 115, network entity 105, device, equipment, computing system, etc. as nodes. For example, the disclosure that the UE 115 is configured to receive information from the network entity 105 also discloses that the first node is configured to receive information from the second node.

[0035] In some embodiments, network entity 105 may communicate with core network 130, or with each other, or both. For example, network entity 105 may communicate with core network 130 via one or more backhaul communication links 120 (such as according to S1, N2, N3 or other interface protocols). In some embodiments, network entity 105 may communicate with each other directly (such as directly between network entities 105) or indirectly (such as via core network 130) via backhaul communication links 120 (such as according to X2, Xn or other interface protocols). In some embodiments, network entity 105 may communicate with each other via midhaul communication link 162 (such as according to midhaul interface protocol) or fronthaul communication link 168 (such as according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162 or fronthaul communication link 168 may be or include one or more wired links (such as electrical links, optical fiber links), one or more wireless links (such as radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155.

[0036] One or more of the network entities 105 described herein may include or may be referred to as base station (BS) 140 (such as transceiver base station, radio BS, NR BS, access point, radio transceiver, Node B, evolved Node B (eNB), next generation Node B or gigabit Node B (any of which may be referred to as gNB), 5G NB, next generation eNB (ng-eNB), home Node B, home evolved Node B or other suitable terms). In some embodiments, network entity 105 (such as BS140) may be implemented in an aggregated (such as monolithic, stand-alone) BS architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (such as a single RAN node, such as BS140).

[0037] In some specific implementations, the network entity 105 may be implemented in a split architecture (such as a split BS architecture, a split RAN architecture), which may be configured to utilize a protocol stack physically or logically distributed between two or more network entities 105 (such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (such as a network configuration sponsored by the O-RAN Alliance) or a virtualized RAN (vRAN) (such as a cloud RAN (C-RAN))). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (such as a near real-time RIC (near RT RIC), a non-real-time RIC (non RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio headend, an intelligent radio headend, a remote radio headend (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the split RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (such as separate physical locations). In some specific implementations, one or more network entities 105 of the split RAN architecture may be implemented as virtual units (such as a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

[0038] The functional split between the CU 160, DU 165, and RU 170 is flexible and can support different functions, depending on which functions are performed at the CU 160, DU 165, and RU 170 (such as network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof). For example, a functional split of the protocol stack can be adopted between the CU 160 and the DU 165, such that the CU 160 can support one or more layers of the protocol stack and the DU 165 can support one or more different layers of the protocol stack. In some specific implementations, the CU 160 can host higher protocol layer (such as layer 3 (L3), layer 2 (L2)) functions and signaling (such as radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 can be connected to one or more DU 165s or RU 170s, and the one or more DU 165s or RU 170s can host lower protocol layers, such as layer 1 (L1) (such as the physical (PHY) layer) or L2 (such as the radio link control (RLC) layer, media access control (MAC) layer) functions and signaling, and can each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack can be adopted between the DU 165 and the RU 170, such that the DU 165 can support one or more layers of the protocol stack and the RU 170 can support one or more different layers of the protocol stack. The DU 165 can support one or more different cells (such as via one or more RU 170s). In some specific implementations, the functional split between the CU 160 and the DU 165 or between the DU 165 and the RU 170 can be within a protocol layer (such as some functions of the protocol layer can be performed by one of the CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, DU 165, or RU 170). The CU 160 can be further functionally split into a CU control plane (CU-CP) and a CU user plane (CU-UP) function. The CU 160 can be connected to one or more DU 165s via an intermediate transport communication link 162 (such as F1, F1-c, F1-u), and the DU 165 can be connected to one or more RU 170s via a fronthaul communication link 168 (such as an open fronthaul (FH) interface). In some specific implementations, the intermediate transport communication link 162 or the fronthaul communication link 168 can be implemented according to the interfaces (such as channels) between the layers of the protocol stack, and the layers of the protocol stack are supported by the corresponding network entities 105 communicating via such communication links.

[0039] In some wireless communication systems, such as wireless communication system 100, the infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (such as to a core network 130). In some embodiments, in an IAB network, one or more network entities 105 (such as IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (such as donor BS 140). One or more donor network entities 105 (such as IAB donors) may communicate with one or more additional network entities 105 (such as IAB nodes 104) via supported access and backhaul links (such as backhaul communication link 120). An IAB node 104 may include an IAB mobile termination (IAB-MT) controlled (such as scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a separate set of antennas for relaying communications with a UE 115, or may share the same antennas of the IAB node 104 (such as an RU 170) for access via the DU 165 of the IAB node 104 (such as referred to as a virtual IAB-MT (vIAB-MT)). In some embodiments, an IAB node 104 may include a DU 165 that supports communication links with additional entities (such as IAB nodes 104, UEs 115) within a relay chain or configuration (such as downstream) of the access network. In such embodiments, one or more components of a split RAN architecture (such as one or more IAB nodes 104 or components of an IAB node 104) may be configured to operate in accordance with the techniques described herein.

[0040] In embodiments where the techniques described herein are applied in the context of a split RAN architecture, one or more components of the split RAN architecture may be configured to support CLI measurements in SBFD operations as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (such as BS 140) may additionally or alternatively be performed by one or more components of the split RAN architecture (such as IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180).

[0041] The UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or user equipment, or some other suitable term, where the "device" may also be referred to as a unit, station, terminal, or client, etc. The UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some specific implementations, the UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, meters, etc.

[0042] As Figure 1 shown, the UE 115 described herein may be capable of communicating with various types of devices, such as other UE 115s that may sometimes act as relays, and network entities 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay BSs, etc.

[0043] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (such as access links) using resources associated with one or more carriers. The term "carrier" may refer to a set of RF spectral resources having a defined physical layer structure for supporting the communication link 125. For example, the carrier for the communication link 125 may include a portion of the RF spectral band (such as a bandwidth part (BWP)), which operates according to one or more physical layer channels for a given radio access technology (such as LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (such as synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. According to the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) and TDD component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any part of the network entity 105 (such as an entity, sub-entity). For example, the terms "transmit", "receive", or "communicate" when referring to the network entity 105 may refer to any part of the network entity 105 of the RAN (such as BS140, CU 160, DU165, RU 170) communicating with another device (such as directly or via one or more other network entities 105).

[0044] The communication link 125 shown in the wireless communication system 100 may include a downlink transmission (such as a forward link transmission) from the network entity 105 to the UE 115, an uplink transmission (such as a reverse link transmission) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry downlink or uplink communication (such as in the FDD mode) or may be configured to carry both downlink and uplink communication (such as in the TDD mode).

[0045] A carrier may be associated with a specific bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths of carriers of a particular radio access technology (such as 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (such as the network entity 105, the UE 115, or both) may have a hardware configuration that supports communication using a specific carrier bandwidth or may be configurable to support communication using one of a set of carrier bandwidths. In some particular implementations, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communication using carriers associated with multiple carrier bandwidths. In some particular implementations, each served UE 115 may be configured to operate using a portion (such as a subband, BWP) or all of the carrier bandwidth.

[0046] The signal waveform transmitted via a carrier may be composed of multiple subcarriers (such as using a multi-carrier modulation (MCM) technique, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing an MCM technique, a resource element may refer to the resource of one symbol period (such as the duration of one modulation symbol) and one subcarrier, where the symbol period and the subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (such as the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively larger number of resource elements (such as during the transmission duration) and a relatively higher order modulation scheme may correspond to a relatively higher communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (such as spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity of communication with the UE 115.

[0047] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, and in some particular implementations, the basic time unit may refer to the sampling period T s = 1 / (Δf max·N f ) seconds, where Δf max can represent the supported subcarrier spacing, and N f can represent the supported discrete Fourier transform (DFT) size. The time intervals of communication resources can be organized according to radio frames each having a specific duration (such as 10 milliseconds (ms)). Each radio frame can be identified by a system frame number (SFN) (such as ranging from 0 to 1023).

[0048] Each frame can include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot can have the same duration. In some specific implementations, a frame can be divided (such as in the time domain) into subframes, and each subframe can be further divided into a certain number of time slots. Alternatively, each frame can include a variable number of time slots, and the number of time slots can depend on the subcarrier spacing. Each time slot can include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a time slot can be further divided into a plurality of mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period can be associated with one or more (such as N f ones) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0049] A subframe, time slot, mini-slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (such as in the time domain), and can be referred to as a transmission time interval (TTI). In some specific implementations, the TTI duration (such as the number of symbol periods in a TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (such as in bursts of shortened TTI (sTTI)).

[0050] Physical channels can be reused according to various techniques to communicate using a carrier. For example, one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels to signal via a downlink carrier. A control region for a physical control channel (such as a control resource set (CORESET)) can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (such as, CORESET) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search a control region for control information according to one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate can refer to the number of control channel resources (such as control channel elements (CCEs)) associated with the coded information for a control information format with a given payload size. The search space set can include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set for transmitting control information to a specific UE 115.

[0051] In some specific implementations, the network entity 105 (such as BS140, RU 170) can be movable and thus provide communication coverage for a moving coverage area 110. In some specific implementations, although different coverage areas 110 associated with different technologies can overlap, different coverage areas 110 can be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies can be supported by different network entities 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of network entities 105 use the same or different radio access technologies to provide coverage for various coverage areas 110.

[0052] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, the network entity 105 (such as BS140) can have similar frame timing, and transmissions from different network entities 105 can be approximately aligned in time. For asynchronous operation, the network entity 105 can have different frame timing, and in some examples, transmissions from different network entities 105 can not be aligned in time. The techniques described herein can be used for synchronous or asynchronous operation.

[0053] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 can be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication can include private communication or group communication and can be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions can include prioritization of services, and such services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency can be used interchangeably herein.

[0054] In some specific implementations, the UE 115 can be configured to communicate directly with other UEs 115 via a device-to-device (D2D) communication link 135 (such as according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some specific implementations, one or more UEs 115 performing D2D communication in a group can be within the coverage area 110 of a network entity 105 such as a BS 140, RU 170, and the network entity can support aspects of such D2D communication configured (such as scheduled) by the network entity 105. In some specific implementations, one or more UEs 115 in such a group can be outside the coverage area 110 of the network entity 105 or otherwise may not be or may not be configured to receive transmissions from the network entity 105. In some specific implementations, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some specific implementations, the network entity 105 can facilitate scheduling resources for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving the network entity 105.

[0055] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which can include at least one control plane entity that manages access and mobility (such as 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 an external network (such as a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity can manage non-access stratum (NAS) functions, such as the mobility, authentication, and bearer management of the UE 115 served by a network entity 105 (such as BS140) associated with the core network 130. User IP packets can be transferred through the user plane entity, and the user plane entity can provide IP address allocation and other functions. The user plane entity can be connected to the IP services 150 of one or more network operators. The IP services 150 can include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet-switched streaming services.

[0056] The wireless communication system 100 can operate using one or more frequency bands in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or the decimeter band because, in terms of length, the wavelength range is approximately one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macrocells can provide service to UEs 115 located indoors. Compared to communications using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, communications using UHF waves can be associated with smaller antennas and shorter ranges (such as less than 100 kilometers).

[0057] The wireless communication system 100 may also operate in the super high frequency (SHF) region (also known as the centimeter band) in the range of 3 GHz to 30 GHz or in the extremely high frequency (EHF) region of the spectrum (such as 30 GHz to 300 GHz) (also known as the millimeter band). In some specific implementations, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and network entities 105 (such as BS 140, RU 170), and the EHF antennas of the corresponding devices may be smaller and closer spaced than UHF antennas. In some specific implementations, such technologies may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the use of frequency bands designated across these frequency regions may vary by country or regulatory body.

[0058] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band) to employ licensed-assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using an unlicensed RF spectrum band, devices such as network entities 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some specific implementations, the operation using an unlicensed band may be based on a carrier aggregation configuration combined with a component carrier operating using a licensed band (such as LAA). Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, device-to-device (D2D) transmissions, and so on.

[0059] The network entity 105 (such as BS 140, RU 170) or the 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) communication, or beamforming. The antennas of the network entity 105 or the UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation or transmit or receive beamforming. For example, one or more BS antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some specific implementations, the antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of antenna ports arranged in multiple rows and columns that the network entity 105 may use to support beamforming for communication with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0060] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (such as network entity 105, UE 115) to shape or steer an antenna beam (such as a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via the antenna elements of an antenna array such that some signals propagating in a particular direction relative to the antenna array experience constructive interference while other signals experience destructive interference. Adjusting the signals communicated via the antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both, to the signals carried via the antenna elements associated with the device. The adjustment associated with each antenna oscillator can be defined by a set of beamforming weights associated with a particular orientation (such as relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0061] Various devices within the wireless communication system 100 may support one or more levels of duplex operation, which may depend on the deployment scenario, duplex mode (such as TDD only, FDD only, or both TDD and FDD), or interference management procedures or associated therewith. In some aspects, the wireless devices (e.g., UE 115, network entity 105, or IAB node 104) within the wireless communication system 100 may support half-duplex or full-duplex operation. For example, network entity 105 may support various types of MIMO communications, including: downlink multi-user MIMO (MU-MIMO), according to which network entity 105 may simultaneously send downlink signaling to two different UEs 115; uplink MU-MIMO, according to which network entity 105 may simultaneously receive uplink signaling from two different UEs 115; or downlink and uplink MU-MIMO (which may be referred to herein as full-duplex operation), according to which network entity 105 may send downlink signaling to a first UE 115 while receiving uplink signaling from a second UE 115. Network entity 105 may further support enhanced MIMO (eMIMO) or further enhanced MIMO (FeMIMO), which may be associated with a FeMIMO beam management session. According to full-duplex operation, a wireless device may be able to transmit and receive simultaneously. In other words, a wireless device may support simultaneous uplink and downlink transmissions (e.g., uplink transmissions and downlink transmissions that at least partially overlap in time).

[0062] In some aspects, network entity 105 and UE 115 may support various evaluation techniques and performance evaluation metrics associated with different deployment scenarios for full-duplex operation (such as for NR duplex). Additionally, network entity 105 and UE 115 may support one or more techniques to support coexistence with other systems in any co-channel or adjacent channel for sub-band non-overlapping full-duplex operation or for dynamic or flexible TDD or for both. For example, network entity 105 and UE 115 may support techniques associated with the evolution of duplex operation of NR TDD across various spectrums (including in unpaired spectrums). In such examples, network entity 105 may support full-duplex operation, UE 115 may support half-duplex operation, and network entity 105 and UE 115 may be configured or expect no restrictions on which frequency ranges are available for use.

[0063] Such techniques may include various full-duplex types or schemes and corresponding metrics for evaluating the performance of such full-duplex types or schemes, CLI mitigation techniques between network entities (such as between gNBs) and between UEs, in-band and inter-band CLI mitigation techniques (such as in the specific implementation of sub-band non-overlapping full-duplex), or metric-based evaluation procedures for the impact of full-duplex operation on half-duplex operation (assuming coexistence in co-channel and adjacent channels). Additionally or alternatively, such techniques may include metric-based evaluation procedures for considering the impact on RF constraints when considering adjacent channel coexistence or for considering the impact on RF constraints when considering self-interference, inter-band CLI and inter-operator CLI at network entity 105, and inter-band CLI and inter-operator CLI at UE 115. Further, such techniques may include antenna or RF and algorithm design for interference mitigation, including antenna isolation, transmit interference management suppression in the receive side portion, filtering, and digital interference suppression. Additionally, such techniques may follow one or more administrative or network specifications associated with full-duplex operation in unpaired spectrums of TDD.

[0064] Furthermore, some systems may support one or more techniques associated with dynamic or flexible TDD or SBFD or both for UE-UE CLI handling. Such one or more techniques may include mechanisms related to UE-to-UE CLI measurement and reporting, coordinated scheduling, spatial domain design, receiver design, UE and network entity transmit and receive timing, power control-based design, or sensing-based mechanisms, as well as other example techniques associated with UE-to-UE CLI handling. In some aspects, such one or more techniques may be associated with the identification of whether the scheme or design includes over-the-air (OTA) or backhaul information exchange.

[0065] In some aspects, the UE 115 and the network entity 105 may support (such as sending or receiving) one or more parameters or information elements to indicate various aspects associated with CLI measurements at the UE 115. The one or more parameters or information elements may be associated with the capabilities of the UE 115 and, in some aspects, may be associated with TDD mode deployment. For example, the cli-RSSI-FDM-DL parameter may indicate whether service cell downlink signals or channels (such as the Physical Downlink Shared Channel (PDSCH) or the Physical Downlink Control Channel (PDCCH)) are supported and the frequency division multiplexing reception of the CLI Received Signal Strength Indicator (RSSI). The cli-SRS-RSRP-FDM_DL parameter may indicate whether service cell downlink signals or channels (such as the PDSCH or the PDCCH) are supported and the frequency division multiplexing reception of the SRS Reference Signal Received Power (RSRP). The cli-RSSI-meas parameter may indicate whether the UE 115 can perform CLI RSSI measurements and support periodic reporting and measurement event triggering. The cli-SRS-RSRP-meas parameter may indicate whether the UE 115 can perform SRS RSRP measurements and support periodic reporting and measurement event triggering based on SRS-RSRP.

[0066] If the UE 115 supports cli-RSSI-meas, the UE 115 may be configured to report the maxNumberCLI-RSSI parameter. The maxNumberCLI-RSSI parameter may define or indicate the maximum number of CLI-RSSI measurement resources for CLI-RSSI measurements. If the UE 115 supports cli-SRS-RSRP-meas, the UE 115 may be configured to report the maxNumberCLI-SRS-RSRP and maxNumberPerSlotCLI-SRS-RSRP parameters. The maxNumberCLI-SRS-RSRP parameter may define or indicate the maximum number of SRS-RSRP measurement resources for SRS-RSRP measurements. The maxNumberPerSlotCLI-SRS-RSRP parameter may define or indicate the maximum number of SRS-RSRP measurement resources per time slot for SRS-RSRP measurements.

[0067] In addition, as described herein, CLI-RSSI may be defined or indicated as the linear average of the total received power (in Watts) observed in a configured set of OFDM symbols in a configured set of measurement time resources in a configured measurement bandwidth from all sources, including co-channel serving and non-serving cells, adjacent channel interference and thermal noise, and other examples. For frequency range (FR) 1 (FR1), the reference point for RSSI may be the antenna connector of UE 115. For FR2, CLI-RSSI may be measured based on the combined signal from the antenna elements corresponding to a given receiver branch. For FR1 and FR2, if receiver diversity is in use by UE 115, the reported CLI RSSI value may not be lower than the corresponding CLI RSSI of any individual receiver branch among the individual receiver branches. In some aspects, CLI-RSSI measurements may be applicable to in-frequency measurements in a connected state, such as RRC_CONNECTED.

[0068] In some systems, the UE 115 and network entities may support one or more scheduling restrictions applied to CLI measurements, and the one or more scheduling restrictions may be associated with the scheduling availability of the UE 115 performing the measurements. The scheduling restrictions may be defined separately for different frequency ranges (FRs), such as for FR1 and FR2. For example, it may be not desired that the UE 115 transmit a physical uplink control channel (PUCCH) message, a physical uplink shared channel (PUSCH) message, or a sounding reference signal (SRS) on an OFDM symbol on which the UE performs a CLI measurement and on a data symbol before the OFDM symbol used for CLI measurements for 15 kHz and 30 kHz SCS (for FR1) or for 60 kHz SCS (for FR2). Additionally or alternatively, for a UE 115 that does not support cli-SRS-RSRP-FDM_DL, it may be not desired that the UE 115 receive a physical downlink control channel (PDCCH) message, a physical downlink shared channel (PDSCH) message, or a channel state information (CSI) reference signal (CSI-RS) for tracking or a CSI-RS for a channel quality indicator (CQI) on an OFDM symbol on which the UE 115 performs an SRS-RSRP measurement and on a data symbol before the OFDM symbol used for SRS-RSRP measurements for 15 kHz and 30 kHz SCS (for FR1) or for 60 kHz SCS (for FR2). Additionally or alternatively, for a UE 115 that does not support cli-RSSI-FDM-DL, it may be not desired that the UE 115 receive a PDCCH message, a PDSCH message, or a CSI-RS for tracking or a CSI-RS for CQI on an OFDM symbol on which the UE 115 performs a CLI-RSSI measurement and on a data symbol before the OFDM symbol used for CLI-RSSI measurements for 15 kHz and 30 kHz SCS (for FR1) or for 60 kHz SCS (for FR2).

[0069] Additionally or alternatively, it may not be desirable for the UE 115 to transmit PUCCH messages, PUSCH messages, or SRS on the OFDM symbol on which the UE 115 performs CLI measurements and on two data symbols prior to the OFDM symbol used for CLI measurements for 60 kHz SCS (for FR1) or for 120 kHz SCS (for FR2). Additionally or alternatively, for a UE 115 that does not support cli-SRS-RSRP-FDM_DL, it may not be desirable for the UE 115 to receive PDCCH messages, PDSCH messages, or CSI-RS for tracking or CSI-RS for CQI on the OFDM symbol on which the UE 115 performs SRS-RSRP measurements and on two data symbols prior to the OFDM symbol used for SRS-RSRP measurements for 60 kHz SCS (for FR1) or for 120 kHz (for FR2). Additionally or alternatively, for a UE 115 that does not support cli-RSSI-FDM-DL, it may not be desirable for the UE 115 to receive PDCCH messages, PDSCH messages, or CSI-RS for tracking or CSI-RS for CQI on the OFDM symbol on which the UE 115 performs CLI-RSSI measurements and on two data symbols prior to the OFDM symbol used for CLI-RSSI measurements for 60 kHz SCS (for FR1) or for 120 kHz SCS (for FR2). Additionally or alternatively, when configuring in-band carrier aggregation in TDD, the scheduling restrictions on the serving cell performing CLI measurements may apply to all serving cells in the same frequency band on symbols that fully or partially overlap with the restricted symbols.

[0070] In some specific implementations, the first UE 115 and the network entity 105 may support one or more signaling-based or configuration-based mechanisms according to which the first UE 115 may measure CLI from the second UE 115 during SBFD symbols in one or more uplink subbands or one or more downlink subbands or a combination thereof. Such signaling-based or configuration-based mechanisms may include one or more of scheduling configurations, capability signaling, or one or more prioritization rules supported by the first UE 115 and the network entity 105 to facilitate inter-subband and intra-subband CLI measurements at the first UE 115 without interrupting other potential communications involving the first UE 115 (such as communications that the first UE 115 is expected to send or receive).

[0071] In some specific implementations, the first UE 115 may send capability signaling (such as assistance information) to the network entity 105 to facilitate agreement or synchronization expectations between the first UE 115 and the network entity 105 regarding whether the first UE 115 is capable of measuring CLI while simultaneously transmitting or receiving another signaling or whether it is capable of prioritizing CLI measurement or one of the other signaling. In some specific implementations, the UE 115 and the network entity 105 may exchange (such as send or receive) signaling associated with or indicating one or more prioritization rules that the first UE 115 may employ. In some other specific implementations, the one or more prioritization rules may be configured, pre-loaded, or downloaded at the first UE 115 and the network entity 105 (such as according to network specifications).

[0072] Figure 2 FIG. 200 shows an example interference measurement diagram supporting CLI measurement in SBFD operations. The interference measurement diagram 200 may be implemented or be made to implement to achieve or facilitate aspects of the wireless communication system 100. For example, the interference measurement diagram 200 illustrates potential interference (and corresponding interference measurements) between various wireless communication devices, including UE 115-a, UE 115-b, UE 115-c, and UE 115-d, as well as network entity 105-a and network entity 105-b. UE 115-a, UE 115-b, UE 115-c, and UE 115-d may each be an example of the UE 115 as illustrated and referred to by Figure 1 illustrated and referred to Figure 1 described. Network entity 105-a and network entity 105-b may be examples of the network entity 105 as illustrated and referred to by Figure 1 illustrated and referred to Figure 1 described. In some specific implementations, one or more of the various wireless communication devices may support techniques associated with inter-UE CLI mitigation, which is associated with sub-band non-overlapping full-duplex scenarios and sub-band partially or fully overlapping full-duplex scenarios.

[0073] As illustrated in interference measurement diagram 200, network entity 105-a may be associated with cell 205-a, and network entity 105-b may be associated with cell 205-b. Within cell 205-a, UE 115-a may send signaling (such as uplink signaling to network entity 105-a) that causes in-cell CLI 210-a at UE 115-b. Similarly, within cell 205-b, UE 115-c may send signaling (such as uplink signaling to network entity 105-b) that causes in-cell CLI 210-b at UE 115-d. In some deployment scenarios, such as where UE 115-b and UE 115-c are relatively close to each other (although served by different cells), the signaling sent by UE 115-c may cause inter-cell CLI 215 at UE 115-b. In some aspects, in scenarios where network entity 105-a and network entity 105-b support dynamic TDD operation, UE 115-b may experience inter-cell CLI 215 from UE 115-c. Thus, UE 115-b may experience in-cell CLI 210-a or inter-cell CLI 215 or both. Additionally, in some deployment scenarios, network entity 105-a may send signaling (such as downlink signaling to UE 115-b) that causes inter-gNB CLI 220.

[0074] In an example where network entity 105-a and network entity 105-b support SBFD, in-cell CLI 210-a, in-cell CLI 210-b, inter-cell CLI 215, and inter-gNB CLI 220 may include inter-subband CLI. In an example where network entity 105-a and network entity 105-b support full or partially overlapping full duplex, in-cell CLI 210-a, in-cell CLI 210-b, inter-cell CLI 215, and inter-gNB CLI 220 may include intra-subband CLI. Thus, in some example deployments where network entity 105-a and network entity 105-b communicate and schedule communications according to a network-side SBFD mode, UE 115-b may experience inter-subband, in-cell, UE-to-UE CLI (such as in-cell CLI 210-a) from UE 115-a and inter-subband, inter-cell, UE-to-UE CLI (such as inter-cell CLI 215) from UE 115-c. Similarly, network entity 105-a and network entity 105-b may each experience a certain amount of inter-subband, inter-gNB CLI (such as inter-gNB CLI 220).

[0075] In some aspects, UE 115-b and network entity 105-a may support inter-UE CLI measurements in SBFD symbols, where an SBFD symbol may refer to a symbol during which network entity 105-a expects to support SBFD communication (such as a symbol during which network entity 105-a expects to receive an uplink signal from UE 115-a and transmit a downlink signal to UE 115-b or vice versa). Additionally, although referred to as SBFD symbols in some examples, UE 115-b and network entity 105-a may support such inter-UE CLI measurements in SBFD time slots, where an SBFD time slot may refer to a time slot during which network entity 105-a expects to support SBFD communication (such as a time slot during which network entity 105-a expects to receive an uplink signal from UE 115-a and transmit a downlink signal to UE 115-b or vice versa).

[0076] To facilitate inter-UE CLI measurements, UE 115-a (and optionally other UEs 115, such as UE 115-c) may transmit CLI reference signals, and UE 115-b may measure the CLI reference signals in one or more downlink subbands of UE 115-b. Such measurement of inter-UE CLI in one or more downlink subbands of UE 115-b may not provide UE 115-b with information associated with inter-UE CLI in one or more uplink subbands of UE 115-b, which may adversely affect the receiver dynamic range or cause receiver AGC blocking or both. For example, in a scenario where UE 115-a and UE 115-b have the same or similar subband configurations (such that at least one uplink subband used by UE 115-a is similar or otherwise identical to an uplink subband used by UE 115-b in terms of the associated frequency range, as may be configured to support network-side SBFD operations), the inter-UE CLI from UE 115-a experienced at UE 115-b may cause in-band (such as within-band) CLI at UE 115-b, which may not be considered in some inter-UE CLI measurement configurations.

[0077] Accordingly, in some embodiments, UE 115-b and network entity 105-b may support an inter-UE CLI measurement mechanism according to which UE 115-b may perform corresponding measurements on CLI reference signals in one or more downlink subbands and in one or more uplink subbands. Accordingly, UE 115-b may measure, or otherwise identify, select, or determine, the RSSI or signal-to-interference-plus-noise ratio (SINR) of inter-subband leakage based on the CLI measurements in one or more downlink subbands, and may measure the RSRP of the in-subband CLI (which affects the receiver dynamic range or receiver AGC blocking or both) based on the CLI measurements in one or more uplink subbands.

[0078] Figure 3 An example signaling diagram 300 supporting CLI measurements in SBFD operations is shown. The signaling diagram 300 may be implemented or be made to implement aspects of wireless communication system 100 or interference measurement diagram 200. For example, signaling diagram 300 illustrates communication between UE 115-a (such as UE 115-a illustrated and referenced by Figure 2 illustrated and referenced Figure 2 ), UE 115-b (such as UE 115-b illustrated and referenced by Figure 2 illustrated and referenced Figure 2 ), and network entity 105 (such as network entity 105-a illustrated and referenced by Figure 2 illustrated and referenced Figure 2 ).

[0079] In some embodiments, UE 115-b may perform an inter-UE CLI measurement 310 associated with the CLI from UE 115-a during an SBFD symbol. Accordingly, UE 115-a may transmit a CLI reference signal 305 during the SBFD symbol, and UE 115-b may measure the CLI reference signal 305 to obtain the inter-UE CLI measurement 310. In some embodiments, UE 115-a may transmit the CLI reference signal 305 based on an indication received from network entity 105-a to transmit the CLI reference signal 305. In other words, network entity 105-a may schedule UE 115-a to transmit the CLI reference signal 305 during the SBFD symbol to facilitate the inter-UE CLI measurement 310 at UE 115-b. In some deployments, UE 115-a and UE 115-b may be configured or allocated the same or similar subbands to support network-side SBFD operations at network entity 105-a. For example, UE 115-a and UE 115-b may each support an uplink subband 315, a downlink subband 320-a, and a downlink subband 320-b. Additionally, although in Figure 3is illustrated in the context of using subbands associated with the same frequency range, but the uplink or downlink subbands used by UE 115-a and UE 115-b may fully or partially overlap.

[0080] UE 115-a may transmit the CLI reference signal 305 via the uplink subband 320, and in some embodiments, UE 115-b may measure the CLI reference signal 305 in the uplink subband 315, the downlink subband 315-a, and the downlink subband 320-b. For example, UE 115-b may be allowed to measure the CLI reference signal 305 (such as the inter-UE CLI reference signal) in the downlink subbands 320-a and 320-b and the uplink subband 315 during the same SBFD symbol or time slot. In such embodiments, UE 115-b may prohibit performing any uplink transmission during the SBFD symbol or time slot and may instead receive and measure the CLI reference signal 305 in the uplink subband 315.

[0081] In some embodiments, UE 115-b may adjust to the transmission timing of UE 115-a to measure the CLI reference signal 305 in both the uplink subband 315 and the downlink subbands 320-a and 320-b. For example, UE 115-b may apply a time-domain offset (such as a constant or fixed time-domain offset) relative to the downlink reference timing in the serving cell. In some aspects, UE 115-b may derive the value of the time-domain offset based on a device-level decision. In some aspects, the time-domain offset may be at least a minimum value, where the minimum value may be signaled, calculated, or defined by network specifications. In other words, UE 115-b may extend the layer 3 (L3) CLI measurement timing adjustment rule for layer 1 (L1) / layer 2 (L2) subband-based inter-UE CLI measurements. Thus, when UE 115-b measures SRS-RSRP and CLI-RSSI, UE 115-b may apply the time-domain offset. In some embodiments, the offset may be associated with the proximity of UE 115-a and UE 115-b (such as the distance between UE 115-a and UE 115-b). For example, UE 115-a and UE 115-b may be expected to be relatively close to each other and have similar uplink timings.

[0082] In addition, although described and illustrated in the context of one uplink subband 315 and two downlink subbands 320-a and 320-b, the described techniques can be applied to any number of uplink subbands and downlink subbands. For example, UE 115-a or UE 115-b or both can support or receive allocations for one uplink subband and one downlink subband, two uplink subbands and two downlink subbands, two uplink subbands and one downlink subband, and so on. In general, UE 115-a or UE 115-b or both can support or receive an allocation for X uplink subbands and Y downlink subbands, where X and Y can be any numbers and can be the same or different.

[0083] In some scenarios, UE 115-b can be scheduled to transmit an uplink signal or receive a downlink signal during an SBFD symbol or time slot during which UE 115-a transmits the CLI reference signal 305. In such scenarios, UE 115-b and network entity 105-a can adopt one or more prioritization rules based on the capabilities of UE 115-b. For example, if UE 115-b is capable of simultaneously performing communication (such as transmitting to or receiving from) with network entity 105-a or another UE 115 and measuring the CLI reference signal 305, then UE 115-b can perform both. Alternatively, if UE 115-b is not capable of simultaneously performing communication (such as transmitting to or receiving from) with network entity 105-a or another UE 115 and measuring the CLI reference signal 305, then UE 115-b can select to perform the communication (such as transmitting or receiving a scheduled uplink or downlink signal) or measure the CLI reference signal 305 according to one or more prioritization rules. Additional details regarding such prioritization rules are provided by Figure 4 Illustration and reference Figure 4 Description.

[0084] Figure 4 Exemplary communication timelines 400, 401, and 402 that support CLI measurement in SBFD operations are shown. Communication timelines 400, 401, and 402 can be implemented or be made to implement to achieve or facilitate aspects of wireless communication system 100, interference measurement diagram 200, or signaling diagram 300. For example, communication timelines 400, 401, and 402 illustrate various exemplary scenarios in which UE 115-b (such as as illustrated by Figure 2 and Figure 3 Illustration and reference Figure 2 and Figure 3The described UE 115-b is scheduled or configured to measure the CLI reference signal 415, receive the downlink signal 420, transmit the uplink signal 425, or any combination thereof, during the SBFD symbol 410, which may be referred to or understood as a CLI resource. In such example scenarios, the UE 115-b may measure the CLI reference signal 415, receive the downlink signal 420, transmit the uplink signal 425, or perform any combination thereof, based on the capabilities of the UE 115-b and, if applicable, one or more prioritization rules.

[0085] As illustrated in the communication timeline 400, the UE 115-b may receive one or more control messages 405 indicating that the UE 115-b is to perform inter-UE CLI measurements during the SBFD symbol 410. In the example of the communication timeline 400, the UE 115-b may not experience a scheduling conflict and may thus measure the CLI reference signal 415 in the uplink subbands (such as any one or more uplink subbands supported or allocated to the UE 115-b) and in the downlink subbands (such as any one or more downlink subbands supported or allocated to the UE 115-b).

[0086] As illustrated in the communication timeline 401, the UE 115-b may receive one or more control messages 405 indicating that the UE 115-b is to perform inter-UE CLI measurements during the SBFD symbol 410 and indicating, configuring, or scheduling the downlink signal 420 during the SBFD symbol 410. In some specific implementations, the UE 115-b may be allowed or capable of simultaneously receiving the downlink signal 420 in the downlink subbands (such as any one or more downlink subbands supported or allocated to the UE 115-b) and receiving and measuring the CLI reference signal 415 in the uplink subbands (such as any one or more uplink subbands supported or allocated to the UE 115-b) in the same SBFD symbol 410 (or the same SBFD time slot). In such specific implementations, the timing of the downlink signal 420 may be associated with the downlink timing from the network entity 105-a, and the timing of the CLI reference signal 415 may be associated with the uplink timing of the UE 115-a (such as the possible or approximate uplink timing).

[0087] Accordingly, UE 115-b can compensate for or otherwise account for such potential timing differences. For example, if the CLI reference signal 415 and the downlink signal 420 are not aligned, UE 115-b can use two fast Fourier transform (FFT) windows to receive the downlink signal 420 and measure the CLI reference signal 415. In some systems, such use of two FFT windows may not be feasible for all devices within the system. Thus, in some embodiments, UE 115-b can send an indication to network entity 105-a reporting UE 115-b's ability to receive the downlink signal 420 in one or more downlink subbands and receive the CLI reference signal 415 (such as an inter-UE CLI reference signal) in one or more uplink subbands simultaneously in the same SBFD symbol 410 (or the same SBFD time slot).

[0088] In some other embodiments, UE 115-b may not have the ability to simultaneously receive the downlink signal 420 in a downlink subband and receive and measure the CLI reference signal 415 in an uplink subband in the same SBFD symbol 410 (or the same SBFD time slot). In such embodiments, UE 115-b can employ a prioritization rule (such as a first prioritization rule) according to which UE 115 selects or prioritizes one of the CLI reference signal 415 or the downlink signal 420. In some embodiments, the prioritization rule can be a fixed or static rule according to which it is expected that UE 115-b prioritizes the CLI reference signal 415 over the downlink signal 420 by default or according to a specification (such as a network specification).

[0089] In such a specific implementation, UE 115-b may support one or more scheduling restrictions associated with the measurement of the CLI reference signal 415. For example, if UE 115-b does not support cli-SRS-RSRP-FDM_DL, it may not be desirable for UE 115-b to receive PDCCH messages, PDSCH messages, or CSI-RS for tracking or CSI-RS for CQI on one or more DL subbands of the SBFD OFDM symbol (on which UE 115-b performs SRS-RSRP measurements on the UL subband of the SBFD OFDM symbol) and on two data symbols before the OFDM symbol used for SRS-RSRP measurements for 60 kHz SCS (for FR1) or for 120 kHz (for FR2). Additionally or alternatively, if UE 115-b does not support cli-RSSI-FDM-DL, it may not be desirable for UE 115-b to receive PDCCH messages, PDSCH messages, or CSI-RS for tracking or CSI-RS for CQI on one or more DL subbands of the SBFD OFDM symbol (on which UE 115-b performs CLI-RSSI measurements on the UL subband of the SBFD OFDM symbol) and on two data symbols before the OFDM symbol used for CLI-RSSI measurements for 60 kHz SCS (for FR1) or for 120 kHz (for FR2). Additionally or alternatively, it may not be desirable for UE 115-b to send PUCCH messages, PUSCH messages, or SRS on the UL subband of the SBFD OFDM symbol (on which the UE performs CLI measurements) and on two data symbols before the OFDM symbol used for CLI measurements for 60 kHz SCS (for FR1) or for 120 kHz SCS (for FR2).

[0090] In some other specific implementations, the prioritization rule may be associated with the resource type of the CLI reference signal 415 or the downlink signal 420, where the resource type may be one of a periodic resource type, a semi-persistent resource type, or an aperiodic resource type. In other words, the prioritization rule may be associated with whether the CLI reference signal 415 is sent periodically, semi-persistently, or aperiodically. In such specific implementations, for example, if the downlink signal 420 is configured via RRC signaling (such as RRC-configured), the UE 115-b may prioritize the CLI reference signal 415 (and prohibit receiving the downlink signal 420) when the CLI reference signal 415 is any one of periodic, semi-persistent, or aperiodic. For a further example, if the downlink signal 420 is semi-statically configured (such as via RRC downlink slot format), the UE 115-b may prioritize the CLI reference signal 415 when the CLI reference signal 415 is aperiodic, and otherwise may prioritize the downlink signal 420 (and discard CLI measurements).

[0091] For a further example, if the downlink signal 420 is dynamically scheduled or indicated, the UE 115-b may prioritize the downlink signal 420 (and discard CLI measurements) when the CLI reference signal 415 is periodic or semi-persistent. Alternatively, if the downlink signal 420 is dynamically scheduled or indicated and the CLI reference signal 415 is aperiodic, the UE 115-b may discard the CLI reference signal 415 (and prioritize the downlink signal 420) or may identify or declare an error. For example, the network specification may define the dynamically scheduled downlink signal 420 and the aperiodic CLI reference signal 415 in the same SBFD symbol 410 as an error, such that the UE 115-b may not expect to receive the downlink control information (DCI) for scheduling the downlink signal 420 during the same set of one or more symbols during which the UE 115-b receives another DCI for the aperiodic CLI reference signal 415. For a further example, if the downlink signal 420 is a downlink CLI reference signal, the UE 115-b may perform CLI measurements for both the downlink CLI reference signal and the CLI reference signal 415 (inter-UE CLI reference signal).

[0092] As illustrated by communication timeline 402, UE 115-b may receive one or more control messages 405 that indicate that UE 115-b is to perform inter-UE CLI measurements during SBFD symbol 410 and indicate, configure, or schedule uplink signal 425 during SBFD symbol 410. In some embodiments, UE 115-b may use a prioritization rule (such as a second prioritization rule) to select or prioritize one of CLI reference signal 415 and uplink signal 425. In some embodiments, the prioritization rule may be associated with the resource type of CLI reference signal 415 or uplink signal 425. For example, the prioritization rule may be associated with whether CLI reference signal 415 is periodic, semi-persistent, or aperiodic.

[0093] For example, if the uplink signal is configured via RRC signaling (such as RRC-configured), then UE 115-b may prioritize CLI reference signal 415 (and prohibit transmission of uplink signal 425) if CLI reference signal 415 is any of periodic, semi-persistent, or aperiodic. For a further example, if the uplink signal is dynamically scheduled or indicated and CLI reference signal 415 is periodic or semi-persistent, then the prioritization rule may indicate that one of uplink signal 425 or CLI reference signal 415 is to be prioritized or may indicate that either uplink signal 425 or CLI reference signal 415 may be prioritized (such as based on a device-level decision at UE 115-b). For a further example, if uplink signal 425 is dynamically scheduled or indicated and CLI reference signal 415 is aperiodic, then UE 115-b may identify or declare an error, or if permitted (according to the prioritization rule), then UE 115-b may convert the scheduled DCI format or receive CLI reference signal 415 and perform CLI measurements. According to the prioritization, UE 115-b may use the uplink subband for the prioritized signal and may or may not use the downlink subband. For example, UE 115-b may still measure CLI reference signal 415 in the downlink subband or may prohibit measuring CLI reference signal 415 in the downlink subband.

[0094] In addition, although various scheduling conflicts are illustrated and described as overlapping during SBFD symbol 410 in the context of the communication timeline, the described prioritization rules (which may be understood as conflict rules) may apply to a set of one or more OFDM symbols during which UE 115-b performs CLI measurements and up to N - OFDM symbols 430 prior to the CLI measurements. In some embodiments, the value of N may be associated with one or both of SCS and FR.

[0095] Figure 5 Illustrates an example process flow 500 that supports CLI measurements in SBFD operations. The process flow 500 may be implemented or be implemented to achieve or facilitate aspects of the wireless communication system 100, the interference measurement diagram 200, the signaling diagram 300, and any one or more of the communication timelines 400, 401, and 402. For example, the process flow 500 illustrates communication between UE 115-a, UE 115-b, and network entity 105-a. As illustrated by Figure 5 Illustrated and referenced by Figure 5 The UE 115-a, UE 115-b, and network entity 105-a described may be examples of the UE 115-a, UE 115-b, and network entity 105-a as illustrated or referenced by Figures 1 to 4 Illustrated or referenced by Figures 1 to 4 Described. In some specific implementations, UE 115-b may be configured or scheduled to receive a CLI reference signal from UE 115-a during an SBFD symbol or time slot, and UE 115-b may selectively measure the CLI reference signal or perform other communication or both, depending on any scheduling conflicts at UE 115-b and the capabilities of UE 115-b.

[0096] In the following description of the process flow 500, operations (such as reporting or providing) may be performed in an order different from the order shown, or operations performed by the example devices may be performed in a different order or at different times. Some operations may also be excluded from the process flow 500, or other operations may be added to the process flow 500. Additionally, although some operations or signaling are shown as occurring at different times for discussion purposes, these operations may actually occur simultaneously.

[0097] At 505, network entity 105-a may send one or more control messages to UE 115-b that include information associated with uplink subbands and downlink subbands and an indication of CLI reference signals in at least the uplink subbands. For example, UE 115-b may receive an indication or allocation of a set of one or more uplink subbands and a set of one or more downlink subbands. In some aspects, the indication or allocation of uplink subbands and downlink subbands at UE 115-b may be associated with network-side SBFD operations. In other words, network entity 105-a may allocate one or more uplink subbands and one or more downlink subbands to each of UE 115-a and UE 115-b, and may use the allocated subbands to schedule communications with UE 115-a and UE 115-b to facilitate SBFD operations at network entity 105-a (whereas each of UE 115-a and UE 115-b may communicate according to half-duplex operation). In some embodiments, UE 115-b may use the CLI reference signals (such as according to an indication in one or more control messages or according to a configured or specified procedure) for corresponding CLI measurements in at least one of the uplink subbands and the downlink subbands (if not for corresponding CLI measurements across multiple uplink subbands or multiple downlink subbands or any combination thereof).

[0098] At 510, UE 115-b may send a message associated with the ability of UE 115-b to receive CLI reference signals via an uplink subband and receive downlink signals via a downlink subband simultaneously. For example, UE 115-a, UE 115-b, and network entity 105-a may schedule or configure CLI measurements at UE 115-b during SBFD symbol 515 (or SBFD time slot), which may result in a scheduling conflict (such as if SBFD symbol 515 is also scheduled for downlink or uplink communication to or from UE 115-b). Accordingly, UE 115-b may send a capability message to indicate the ability of UE 115-b to simultaneously measure CLI reference signals from UE 115-a and perform other communications (such as data communications) with network entity 105-a.

[0099] At 520, UE 115-b may receive a CLI reference signal from UE 115-a during the SBFD symbol 515. In some embodiments, UE 115-b may measure the CLI reference signal in at least one of the uplink subband and the downlink subband according to the capabilities of UE 115-b and according to any other communication scheduled for UE 115-b during the SBFD symbol 515 (such as any other uplink or downlink signal). For example, at 525, network entity 105-a may send a downlink signal to UE 115-b during the SBFD symbol 515. Additionally or alternatively, at 530, UE 115-b may be scheduled to send an uplink signal during the SBFD symbol 515.

[0100] In some embodiments, such as in embodiments where UE 115-b is capable of performing CLI measurement and downlink data communication simultaneously, UE 115-b may receive and measure the CLI reference signal from UE 115-a and receive the downlink signal from network entity 105-a. In such embodiments, UE 115-b may receive the downlink signal via the downlink subband and may receive and measure the CLI reference signal via the uplink subband. In some other embodiments, such as in embodiments where UE 115-b is not capable of performing CLI measurement and downlink data communication simultaneously, UE 115-b may prioritize one of the CLI reference signal and the downlink signal and may discard the deprioritized one of the CLI reference signal and the downlink signal. In such embodiments, UE 115-b may prioritize one of the CLI reference signal and the downlink signal according to a prioritization rule (such as a first prioritization rule), as described in Figure 4 more detail.

[0101] In embodiments where UE 115-b is scheduled to send an uplink signal and receive the CLI reference signal during the SBFD symbol 515, UE 115-b may prioritize or otherwise select one of the CLI reference signal and the uplink signal and may discard the deprioritized one of the CLI reference signal and the uplink signal. In such embodiments, UE 115-b may prioritize one of the CLI reference signal and the uplink signal according to a prioritization rule (such as a second different prioritization rule), as described in Figure 4 more detail.

[0102] At 535, in some embodiments, UE 115-b may measure CLI reference signals in the downlink subbands and obtain inter-subband CLI measurements. At 540, in some embodiments, UE 115-b may measure CLI reference signals in the uplink subbands and obtain intra-subband CLI measurements. Thus, UE 115-b may obtain one or both of inter-subband CLI measurements and intra-subband CLI measurements during the SBFD symbol 515. In some aspects, UE 115-b may measure inter-subband CLI via a metric of RSSI or SINR or both, and may measure intra-subband CLI via a metric of RSRP or RSSI or both.

[0103] At 545, in some embodiments, UE 115-b may send a measurement report associated with the respective CLI measurements in at least one of the uplink subbands and the downlink subbands. In such embodiments, UE 115-b may send the measurement report to network entity 105-a, and network entity 105-a may receive and use the information conveyed by the measurement report for future scheduling decisions involving one or both of UE 115-a and UE 115-b.

[0104] At 550, UE 115-b may use the intra-subband CLI measurements to adjust the receiver dynamic range or the receiver AGC or both via a metric of RSRP or RSSI or both.

[0105] At 555, UE 115-b may communicate with network entity 105-a based on one or both of the inter-subband CLI measurements and the intra-subband CLI measurements. For example, network entity 105-b may use the information conveyed by the measurement report to schedule communications to reduce or limit the amount of inter-subband leakage experienced between UE 115-a and UE 115-b. Additionally or alternatively, UE 115-b may perform communications using the adjusted receiver dynamic range or the adjusted AGC, and UE 115-b may adjust one or both of the adjusted receiver dynamic range or the adjusted AGC based on the intra-subband CLI measurements.

[0106] Figure 6FIG. 600 is a block diagram of an example device 605 that supports CLI measurements in SBFD operations. The device 605 may communicate (such as wirelessly) with one or more network entities (such as one or more components of one or more network entities 105), one or more UEs 115, or any combination thereof. The device 605 may include components for two-way voice and data communication, including components for sending and receiving communications, such as a communication manager 620, an input / output (I / O) controller 610, a transceiver 615, an antenna 625, a memory 630, code 635, and a processor 640. These components may communicate electronically via one or more buses (such as bus 645) or otherwise be coupled (such as operatively, communicatively, functionally, electronically, electrically).

[0107] The I / O controller 610 may manage input signals and output signals of the device 605. The I / O controller 610 may also manage peripheral devices not integrated into the device 605. In some embodiments, the I / O controller 610 may represent a physical connection or port to an external peripheral device. In some embodiments, the I / O controller 610 may utilize an operating system, such as or another known operating system. Additionally or alternatively, the I / O controller 610 may represent or interact with a modem, a keyboard, a mouse, a touch screen, or similar device. In some embodiments, the I / O controller 610 may be implemented as part of a processor or processing system (such as processor 640). In some embodiments, a user may interact with the device 605 via the I / O controller 610 or via hardware components controlled by the I / O controller 610.

In some specific embodiments, the processor 640 may be configured to operate a memory array using a memory controller. In some other specific embodiments, the memory controller may be integrated into the processor 640. The processor 640 may be configured to execute computer-readable instructions stored in a memory such as the memory 630 to cause the device 605 to perform various functions such as functions or tasks that support CLI measurements in SBFD operations.

[0111] In some specific embodiments, the processor 640 may be a component of a processing system. A processing system generally may refer to a system or series of machines or components that receive inputs and process those inputs to produce a set of outputs that may be passed to other systems or components such as, for example, other components of the device 605.

[0115] In some specific implementations, to support receiving the CLI reference signal via both the uplink subband and the downlink subband, the communication manager 620 may be configured to or otherwise support components for: receiving the CLI reference signal from a second UE according to a time-domain offset relative to a symbol boundary associated with downlink reception in the downlink subband, where the time-domain offset is associated with the transmission timing of the second UE from which the CLI reference signal is received.

[0116] In some specific implementations, the communication manager 620 may be configured to or otherwise support components for: sending a message associated with the ability of the UE to receive the CLI reference signal via the uplink subband and receive a downlink signal via the downlink subband simultaneously, where conveying the first signal via the uplink subband and the second signal via the downlink subband is associated with the ability of the UE.

In some specific implementations, the downlink signal may include a downlink control channel message, a downlink shared channel message, or CSI-RS.

[0118] In some specific implementations, to support conveying at least one of the first signal via the uplink subband and the second signal via the downlink subband, the communication manager 620 may be configured to or otherwise support components for: receiving the CLI reference signal via the uplink subband during the SBFD symbol, where the first signal includes the CLI reference signal.

[0120] In some specific implementations, to support conveying at least one of the first signal via the uplink subband and the second signal via the downlink subband, the communication manager 620 may be configured to or otherwise support components for: receiving the CLI reference signal via the uplink subband during the SBFD symbol according to the CLI reference signal having priority over the downlink signal.

[0122] In some specific implementations, the priority sorting rule indicates that the CLI reference signal is by default prior to the downlink signal. In some specific implementations, the priority sorting rule indicates that whether the CLI reference signal is prior to the downlink signal is associated with a first resource type of the CLI reference signal and a second resource type of the downlink signal. In some specific implementations, the first resource type includes one of periodic, semi-persistent, or aperiodic, and the second resource type includes one of statically configured, semi-statically indicated, or dynamically scheduled.

[0123] In some specific implementations, according to the downlink signal being configured via RRC signaling, the CLI reference signal has a higher priority than the downlink signal. In some specific implementations, the downlink signal is configured semi-statically. In some specific implementations, when the CLI reference signal is configured aperiodically, the CLI reference signal is prioritized, and when the CLI reference signal is configured semi-persistently or periodically, the CLI reference signal is deprioritized. In some specific implementations, according to the downlink signal being configured dynamically, the downlink signal has a higher priority than the CLI reference signal. In some specific implementations, the downlink signal is configured dynamically, and the CLI reference signal is configured aperiodically. In some specific implementations, the downlink signal being configured dynamically and the CLI reference signal being configured aperiodically are associated with an error condition. In some specific implementations, the UE discards the CLI reference signal according to the error condition.

[0124] In some specific implementations, the prioritization rule is applied to the SBFD symbol and several symbols before the SBFD symbol. In some specific implementations, the several symbols are associated with SCS or FR or both. In some specific implementations, the communication manager 620 may be configured to or otherwise support components for: receiving a message for scheduling an uplink signal during the SBFD symbol, wherein conveying the first signal during the SBFD symbol is associated with the prioritization rule between the uplink signal and the CLI reference signal.

[0126] In some specific implementations, to support the conveyance of at least one of the first signal via the uplink sub-band and the second signal via the downlink sub-band, the communication manager 620 may be configured to or otherwise support components for: transmitting the uplink signal via the uplink sub-band during the SBFD symbol, where according to the uplink signal taking precedence over the CLI reference signal, the first signal includes the uplink signal and excludes the CLI reference signal. In some specific implementations, to support the conveyance of at least one of the first signal via the uplink sub-band and the second signal via the downlink sub-band, the communication manager 620 may be configured to or otherwise support components for: receiving the CLI reference signal via the downlink sub-band during the SBFD symbol, where the second signal includes the CLI reference signal.

[0127] In some specific implementations, the prioritization rule indicates whether the CLI reference signal takes precedence over the uplink signal and is associated with a first resource type of the CLI reference signal and a second resource type of the uplink signal. In some specific implementations, the first resource type includes one of periodic, semi-persistent, or aperiodic, and the second resource type includes one of statically configured, semi-statically indicated, or dynamically scheduled.

[0128] In some specific implementations, according to the uplink signal being configured via RRC signaling, the CLI reference signal takes precedence over the uplink signal. In some specific implementations, the uplink signal is dynamically configured, and the CLI reference signal is configured periodically or semi-persistently. In some specific implementations, the prioritization rule indicates that the CLI reference signal or the uplink signal is prioritized. In some specific implementations, the uplink signal is dynamically configured, and the CLI reference signal is configured aperiodically. In some specific implementations, the uplink signal being dynamically configured and the CLI reference signal being configured aperiodically is associated with an error condition or a selection state in which the UE can select one of the uplink signal or the CLI reference signal. In some specific implementations, the prioritization rule is applied to the SBFD symbol and several symbols before the SBFD symbol. In some specific implementations, the several symbols are associated with SCS or FR or both.

[0129] In some specific implementations, the corresponding CLI measurement in at least one of the uplink sub-band and the downlink sub-band includes a first CLI measurement associated with the uplink sub-band and a second CLI measurement associated with the downlink sub-band. In some specific implementations, the first CLI measurement is associated with in-band interference measurement, and the second CLI measurement is associated with inter-band interference measurement. In some specific implementations, the UE uses the in-band interference measurement associated with the uplink sub-band to adjust the receiver dynamic range or the receiver AGC or both via metrics of RSRP or RSSI, and the UE uses the inter-band interference measurement associated with the downlink sub-band to measure inter-band leakage via metrics of RSSI or SINR.

Although the communication manager 620 is illustrated as a component of the transceiver 615, in some specific implementations, one or more functions described with reference to the communication manager 620 may be supported or performed by the transceiver 615, the processor 640, the memory 630, the code 635, or any combination thereof. For example, the code 635 may include instructions executable by the processor 640 to cause the device 605 to perform aspects of the CLI measurement in the SBFD operations described herein, or the processor 640 and the memory 630 may be otherwise configured to perform or support such operations.

The code 730 may be stored in a non-transitory computer-readable medium such as the system memory or another type of memory. In some embodiments, the code 730 may not be directly executable by the processor 735 but may cause a computer (such as when compiled and executed) to perform the functions described herein. In some embodiments, the memory 725 may particularly include BIOS, which may control basic hardware or software operations, such as interactions with peripheral components or devices.

[0135] The processor 735 may include intelligent hardware devices such as general-purpose processors, DSPs, ASICs, CPUs, FPGAs, microcontrollers, programmable logic devices, discrete gate or transistor logic components, discrete hardware components, or any combination thereof. In some embodiments, the processor 735 may be configured to operate a memory array using a memory controller. In some other embodiments, the memory controller may be integrated into the processor 735. The processor 735 may be configured to execute computer-readable instructions stored in a memory such as the memory 725 to cause the device 705 to perform various functions (such as functions or tasks supporting CLI measurements in SBFD operations). For example, the device 705 or components of the device 705 may include the processor 735 and the memory 725 coupled to the processor 735, which are configured to perform the various functions described herein. The processor 735 may be an example of a cloud computing platform such as one or more physical nodes and supporting software such as an operating system, virtual machine, or container instance, which may host functions (such as by executing the code 730) to perform the functions of the device 705. The processor 735 may be any one or more suitable processors capable of executing scripts or instructions of one or more software programs stored in the device 705 (such as within the memory 725).

[0136] In some specific implementations, the processor 735 can be a component of a processing system. A processing system generally refers to a system or a series of machines or components that receive inputs and process these inputs to produce a set of outputs (which can be passed to other systems or components such as device 705). For example, the processing system of device 705 can refer to a system that includes various other components or sub-components of device 705 (such as processor 735, or transceiver 710, or communication manager 720, or a combination of other components or components of device 705). The processing system of device 705 can interface with other components of device 705 and can process information (such as inputs or signals) received from other components or output information to other components. For example, the chip or modem of device 705 can include a processing system and one or more interfaces for outputting information or for obtaining information or both.

[0137] One or more interfaces can be implemented as or otherwise include a first interface configured to output information and a second interface configured to obtain information or the same interface configured to output information and obtain information, and other specific implementations. In some specific implementations, one or more interfaces can refer to the interface between the processing system of a chip or modem and a transmitter such that device 705 can transmit information output from the chip or modem. Additionally or alternatively, in some specific implementations, one or more interfaces can refer to the interface between the processing system of a chip or modem and a receiver such that device 705 can obtain information or signal inputs, and this information can be passed to the processing system. Those of ordinary skill in the art will readily recognize that the first interface can also obtain information or signal inputs, and the second interface can also output information or signal outputs.

[0138] In some specific implementations, the bus 740 can support communication within a protocol layer of a protocol stack (such as within the protocol layer). In some specific implementations, the bus 740 can support communication associated with a logical channel of a protocol stack (such as between protocol layers of the protocol stack), which communication can include communication executed within components of device 705 or communication executed between different components that can be co-located or located at different positions of device 705 (such as where device 705 can refer to a system in which one or more of communication manager 720, transceiver 710, memory 725, code 730, and processor 735 can be located in one of these different components or divided between different components).

[0139] In some specific implementations, the communication manager 720 may manage various aspects of communication with the core network 130 (such as via one or more wired or wireless backhaul links).

[0149] In some specific implementations, the prioritization rule indicates that the CLI reference signal is by default prior to the downlink signal. In some specific implementations, the prioritization rule indicates that whether the CLI reference signal is prior to the downlink signal is associated with a first resource type of the CLI reference signal and a second resource type of the downlink signal. In some specific implementations, the first resource type includes one of periodic, semi-persistent or aperiodic, and the second resource type includes one of statically configured, semi-statically indicated or dynamically scheduled.

[0150] In some specific implementations, according to the downlink signal configured via RRC signaling, the CLI reference signal is prior to the downlink signal. In some specific implementations, the downlink signal is semi-statically configured. In some specific implementations, when the CLI reference signal is configured aperiodically, the CLI reference signal is prioritized, and when the CLI reference signal is configured semi-persistently or periodically, the CLI reference signal is deprioritized.
