HANDLING OF CROSS LINK INTERFERENCE COLLISIONS WITH REFERENCE SIGNAL MEASUREMENTS

FIELD OF TECHNOLOGY

The following relates to wireless communications, including handling of cross link interference collisions with reference signal measurements.

BACKGROUND

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

Generally, the described techniques provide various mechanisms that support wireless communications in a wireless network. Generally, the described techniques provide various mechanisms that support wireless communications in a wireless network. Broadly, aspects of the described techniques support various mechanisms that prescribe approach (es) for a user equipment (UE) to signal its support for performing layer three (L3) radio resource management (RRM) and CLI measurements colliding during a symbol and/or how to responds when such collisions occur. For example, a UE may signal its support (or lack of support) for both L3 RRM and CLI measurements where L3 RRM and CLI resources collide during a symbol. The support (or lack of support) may be signaled in a UE capability signal and/or in a UE assistance information signal. For example, the UE may identify or otherwise determine its measurement capability for CLI and L3 RRM resources colliding in a symbol. The UE may transmit an indication of its capability to its serving base station and then, during CLI/L3 RRM resource collision within the symbol, perform CLI and/or L3 RRM measurements according to its indicated capability. In the situation where the UE does not support both measurements during the symbol (e.g., as indicated in the capability report) , various other solutions are also described. For example, the specification may define the default measurement to perform (e.g., prioritizing one or the other of CLI or L3 RRM measurements) , the base station may signal which measurement to perform, the UE indicates its measurement preferences, etc. In the situation where the UE is not capable of performing both measurements in CLI and L3 RRM resources that collide in the symbol, proposed are solutions to address timing issues, such as when the L3 RRM and CLI, or vice versa, resources are not time aligned.

DETAILED DESCRIPTION

Some wireless communication systems support layer three (L3) radio resource management (RRM) measurements by a user equipment (UE) using channel state reference signals, beam management reference signals, tracking reference signals, and the like. L3 RRM measurements may be reported by the UE to the base station, and used for link management and mobility. Some wireless communication systems may also support cross link interference (CLI) measurements by a UE of transmissions from neighboring UEs/base stations (which may also be referred to as aggressor devices) . Such CLI measurements may be reported and used for interference mitigation by the base station. In some situations, the RRM related reference signals and the CLI measurement signals collide in the same symbol. In this situation, such wireless communication systems do not require the UE to perform both measurements, e.g., due to timing differences between serving base station reference signal transmissions and reference signal transmission from aggressor UE (s) . Moreover, UEs may be unable to perform colliding measurements due to separate fast Fourier transform (FFT) windows used for each measurement. Accordingly, such wireless communication systems prescribe a default rule where, when the CLI and L3 RRM resources collide in or around a symbol, the UE prioritizes CLI measurements over the L3 RRM measurements. This approach limits the UE’s and/or base station’s link management, resource allocation, handover, etc., decisions based on a more comprehensive interference picture at the UE.

Aspects of the disclosure are initially described in the context of wireless communications systems. Generally, the described techniques provide various mechanisms that support wireless communications in a wireless network. Broadly, aspects of the described techniques support various mechanisms that prescribe approach (es) for the UE to signal its support for performing L3 RRM and CLI measurements colliding during a symbol and/or how to responds when such collisions occur. For example, a UE may signal its support (or lack of support) for both L3 RRM and CLI measurements where RRM and CLI resources collide during a symbol. The support (or lack of support) may be signaled in a UE capability signal and/or in a UE assistance information signal. For example, the UE may identify or otherwise determine its measurement capability for CLI and RRM resources colliding in a symbol. The UE may transmit an indication of its capability to its serving base station and then, during CLI/RRM resource collision within the symbol, perform CLI and/or L3 RRM measurements according to its indicated capability. In the situation where the UE does not support both measurements during the symbol (e.g., as indicated in the capability report) , various other solutions are also described. For example, the specification may define the default measurement to perform (e.g., prioritizing one or the other of CLI or L3 RRM measurements) , the base station may signal which measurement to perform, the UE indicates its measurement preferences, etc. In the situation where the UE is not capable of performing both measurements in CLI and L3 RRM resources that collide in the symbol, proposed are solutions to address timing issues, such as when the RRM and CLI, or vice versa, resources are not time aligned.

Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to handling of CLI collisions with reference signal measurements.

FIG. 1 illustrates an example of a wireless communications system 100 that supports handling of CLI collisions with reference signal measurements in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communications system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

The base stations 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may be devices in different forms or having different capabilities. The base stations 105 and the UEs 115 may wirelessly communicate via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a base station 105 and a UE 115 may support the communication of signals according to one or more radio access technologies.

The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, the base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment) , as shown in FIG. 1.

The base stations 105 may communicate with the core network 130, or with one another, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface) . The base stations 105 may communicate with one another over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations 105) , or indirectly (e.g., via core network 130) , or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

One or more of the base stations 105 described herein may include or may be referred to by a person having ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a Home NodeB, a Home eNodeB, or other suitable terminology.

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

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

The UEs 115 and the base stations 105 may wirelessly communicate with one another via one or more communication links 125 over one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.

In some examples (e.g., in a carrier aggregation configuration) , a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN) ) and may be positioned according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode where initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode where a connection is anchored using a different carrier (e.g., of the same or a different radio access technology) .

The communication links 125 shown in the wireless communications system 100 may include uplink transmissions from a UE 115 to a base station 105, or downlink transmissions from a base station 105 to a UE 115. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .

A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a number of determined bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the base stations 105, the UEs 115, or both) may have hardware configurations that support communications over a particular carrier bandwidth or may be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include base stations 105 or UEs 115 that support simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating over portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

Signal waveforms transmitted over a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) . Thus, the more resource elements that a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE 115. A wireless communications resource may refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams) , and the use of multiple spatial layers may further increase the data rate or data integrity for communications with a UE 115.

One or more numerologies for a carrier may be supported, where a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.

The time intervals for the base stations 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T _s = 1/ (Δf _max·N _f) seconds, where Δf _max may represent the maximum supported subcarrier spacing, and N _f may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .

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

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

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

Each base station 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a base station 105 (e.g., over a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) , or others) . In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the base station 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with geographic coverage areas 110, among other examples.

A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a lower-powered base station 105, as compared with a macro cell, and a small cell may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A base station 105 may support one or multiple cells and may also support communications over the one or more cells using one or multiple component carriers.

In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.

In some examples, a base station 105 may be movable and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, the overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timings, and transmissions from different base stations 105 may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.

Some UEs 115, such as MTC or IoT devices, may be low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that makes use of the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception simultaneously) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 include entering a power saving deep sleep mode when not engaging in active communications, operating over a limited bandwidth (e.g., according to narrowband communications) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.

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

In some examples, a UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol) . One or more UEs 115 utilizing D2D communications may be within the geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of a base station 105 or be otherwise unable to receive transmissions from a base station 105. In some examples, groups of the UEs 115 communicating via D2D communications may utilize a one-to-many (1: M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, a base station 105 facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs 115 without the involvement of a base station 105.

In some systems, the D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115) . In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communications, or with both.

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

Some of the network devices, such as a base station 105, may include subcomponents such as an access network entity 140, which may be an example of an access node controller (ANC) . Each access network entity 140 may communicate with the UEs 115 through one or more other access network transmission entities 145, which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs) . Each access network transmission entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station 105) .

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

The wireless communications system 100 may also operate in a super high frequency (SHF) region using frequency bands from 3 GHz to 30 GHz, also known as the centimeter band, or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) , also known as the millimeter band. In some examples, the wireless communications system 100 may support millimeter wave (mmW) communications between the UEs 115 and the base stations 105, and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate use of antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body.

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

A base station 105 or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a base station 105 may be located in diverse geographic locations. A base station 105 may have an antenna array with a number of rows and columns of antenna ports that the base station 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for a signal transmitted via an antenna port.

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

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

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

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

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

A receiving device (e.g., a UE 115) may try multiple receive configurations (e.g., directional listening) when receiving various signals from the base station 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may try multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .

The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. A Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate over logical channels. A Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a base station 105 or a core network 130 supporting radio bearers for user plane data. At the physical layer, transport channels may be mapped to physical channels.

The UEs 115 and the base stations 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly over a communication link 125. HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (e.g., automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, where the device may provide HARQ feedback in a specific slot for data received in a previous symbol in the slot. In other cases, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.

A UE 115 may identify a capability of the UE 115 to support a CLI measurement on a first frequency resource of a symbol period and a L3 RRM measurement on a second frequency resource of the symbol period, the second frequency resource different than the first frequency resource. The UE 115 may transmit, to a base station 105, a message indicating the identified capability of the UE 115. The UE 115 may perform, during the symbol period and based at least in part on the message, the CLI measurement of CLI from one or more aggressor UEs, the L3 RRM measurement of one or more RRM signals from the base station 105, or both.

A base station 105 may receiving a message from a UE 115 indicating a capability of the UE 115 to support for the UE 115 to perform a CLI measurement on a first frequency resource of a symbol period, to perform a L3 RRM measurement on a second frequency resource of the symbol period, or both, the second frequency resource different than the first frequency resource. The base station 105 may transmit a RRM signal during the symbol period. The base station 105 may receive, based at least in part on the message, a measurement report from the UE 115 indicating a result of the UE 115 performing the CLI measurement of CLI from one or more aggressor UEs 115, the RRM measurement signal from the base station 105, or both, during the symbol period.

FIG. 2 illustrates an example of a wireless communication system 200 that supports handling of CLI collisions with reference signal measurements (e.g., L3 RRM measurements) in accordance with aspects of the present disclosure. In some examples, wireless communication system 200 may implement aspects of wireless communication system 100. Wireless communication system 200 may include base station 205, base station 210, UE 215, UE 220, and/or UE 225, which may be examples of the corresponding devices described herein. In some aspects, base station 205 may be a serving base station for UE 215 and UE 220 and base station 210 may be a serving base station with UE 225. In some aspects, UE 220 may be a victim UE and UE 215 and/or UE 225 may be aggressor UEs with respect to CLI introduced to UE 220.

CLI generally refers to UE-to-UE interference. For example, transmissions from UE 215 may introduce CLI from the perspective of UE 220. Similarly, transmissions from UE 225 may introduce CLI from the perspective of UE 220. To address CLI, a network typically configures a UE (e.g., UE 220 in this example) to measure, in its downlink, the uplink transmissions from another UE (e.g., UE 215 and/or UE 225) . For example, UE 220 may be configured by base station 205 to measure and report transmissions from UE 215 (e.g., intra-cell CLI) and/or UE 225 (e.g., inter-cell CLI) for link management and optimization. Based on the measurement and reporting from UE 220, the network may understand how UEs interfere with each other in the situation where their uplink/downlink transmission directions conflict (e.g., due to flexible, such as different, TDD uplink/downlink configurations for the UEs) .

CLI measurement and reporting mechanisms are generally performed at L3. For example, UE 220 may identify a reference signal received power (RSRP) , reference signal strength indicator (RSSI) , channel state information (CSI) , channel quality information (CQI) , signal-to-interference-noise ratio (SINR) , and the like, based on measurement of transmissions from UE 215 and/or UE 225. The measurement resource configuration may be provided in measurement objects indicated by base station 205 to UE 220. The configuration may include, for CLI measurements resources such as CLI reference signal (RS) transmissions, periodicity, frequency resource blocks, OFDM symbols where the CLI signals are to be transmitted from UE 215 and/or UE 225 and measured by UE 220. In the situation where the RSRP measurement is configured, the resource configuration can also include information about the reference signal (e.g., SRS) sequence to be measured. Accordingly, CLI may occur between UEs in different cells and/or in the same cell. For example, UE 215 and/or UE 220 may introduce CLI for UE 225, UE 220 and/or UE 225 may introduce CLI for UE 215, and so forth.

The network may also perform L3 RRM measurements for link optimization and mobility. For example, the RRM measurements may include UEs (e.g., UE 220 in this example) measuring reference signal transmissions, such as CSI-RS transmissions, beam management transmissions, and the like, from base station 205. UE 220 (in this example) may identify or otherwise determine the RSRP, RSSI, etc., based on the reference signal transmissions from base station 205. UE 220 may transmit a measurement report (e.g., a feedback report, such as a L3 RRM report) to base station 205 indicating the results of the measurements, which uses is information for link management, mobility, and the like.

In some wireless communication systems, UEs are not required to support measurement of CLI and reception of serving cell downlink channel/signal PDSCH/PDCCH and CSI-RS for tracking and CQI in the same OFDM symbol (e.g., in a same symbol period) . This may be due to the serving cell downlink channel/signal and the CLI resource from the aggressor UE (s) (e.g., UE 215 and/or UE 225 in this example) having different propagation timing. For example, a UE may use its serving cell uplink transmit timing to receive the CLI based on the aggressor UE and victim UE (e.g., UE 220 in this example) being close to each other (e.g., which may minimize any propagation delay to a negligible level) , based on the aggressor UE and victim UE having the same propagation delay to their respective serving base stations, and the like. Generally, separate fast Fourier transform (FFT) windows are used by the UE to receive CLI measurement resources and to receive serving cell channel/signals. UE’s typically report such capabilities to the serving base station (e.g., using a cli-SRS-RSRP-FDM_DL field/indication, cli-RSSI-FDM-DL field/indication, corresponding to feature groups 17-3 and/or 17-4) . Generally, if the UE does not support cli-RSRP-FDM_DL and cli-RSSI-FDM-DL (e.g., if the UE does not support performing both CLI and L3 RRM measurements in the same symbol) , the CLI measurement is prioritized to support dynamic prioritization of CLI measurement resources. In this situation, the PDSCH/PDCCH and CSI-RS for tracking and CQI is avoided (e.g., not performed) . That is, in the situation where the victim UE does not support simultaneous CLI and reception of PDSCH/PDCCH and CSI-RS for tracking and CQI, some wireless communication systems prioritize the CLI measurements over the reception of PDSCH/PDCCH and CSI-RS for tracking and CQI.

Otherwise the UE would need to decode the DCI scheduling the PDSCH or CSI-RS for tracking and CQI to know whether the collision between the PDSCH or CSI-RS for tracking and CQI and the CLI resource is in the same symbol. PDCCH is normally not dynamically configured (e.g., except for PDCCH adaptation for power savings or in an unlicensed band) , this follows the same design as PDSCH and CSI-RS for tracking and CQI as they are all physical layer operations (e.g., L1 operations) . In contrast, CLI measurements use an RRC semi-statically configured mechanism. Prioritizing CLI measurement removes dynamic operations of the UE, e.g., as long as a valid CLI resource is configured and assembled. The UE will measure the CLI irrespective of whether PDSCH/PDCCH and CSI-RS for tracking and CQIs configured in the same symbol or not. For example, in some wireless communication systems where the UE does not support cli-RSRP-FDM_DL, the UE is not expected to receive PDCCH/PDSCH/CSI-RS for tracking/CSI-RS for CQI on OFDM symbols in which the UE performs SRS-RSRP measurements. In the situation where the UE does not support cli-RSSI-FDM-DL, the UE is not expected to receive PDCCH/PDSCH/CSI-RS for tracking/CSI-RS for CQI on OFDM symbols in which the UE performs CLI-RSSI measurements.

Accordingly, in some situations RRM measurement resources may be scheduled or otherwise conflict with CLI measurement resources in the same OFDM symbol (e.g., in the same symbol period) . Aspects of the described techniques provide various mechanisms which may be utilized in the situation where the collisions between the configured CLI measurement resources and the L3 RRM measurement resources occur in the symbol period. In some aspects, the L3 RRM measurements may correspond to the L3 CSI-RS measurement being based on the CSI-RS for RRM and mobility control. For example, aspects of the described techniques address receive timing of CLI measurement resources being different from receive timing of L3 CSI-RS measurement resources (e.g., the L3 RRM measurement resources) . Simultaneous reception of both resources on the same symbol may require separate FFT windows, which may be an optional feature implemented at the UE. Moreover, aspects of the described techniques provide, in the situation where the UE does not support simultaneous reception of both measurement resources, which resources are to be prioritized. Unlike the collision between CLI measurement resources and PDSCH/PDCCH and CSI-RS for tracking and CQI, L3 CSI-RS measurement resources may be selected (e.g., there is no dynamic prioritization operation of the UE) . This may provide a more flexible strategy for handling the collision between CLI measurement and L3 CSI-RS measurement in the same symbol period. Accordingly, aspects of the described techniques provide for a capability for collisions between CLI measurement and L3 CSI-RS measurements in the same symbol and/or for prioritization between CLI measurement or L3 CSI-RS measurement when they are configured on the same symbol period. As discussed, L3 CSI-RS measurements may correspond to the L3 RRM measurements according to aspects of the described techniques.

For example, aspects of the described techniques may provide for UE 220 (in this example) to determine or otherwise identify its ability to support CLI measurement and L3 RRM measurements (e.g., L3 CSI-RS measurements) during the same symbol period. The CLI measurement resources may be FDM with respect to the L3 RRM measurement resources (e.g., may be on different frequency resources, such as a first frequency resource and second frequency resource) during the symbol period. UE 220 may transmit to base station 205 (in this example) a message indicating the capability of UE 220 to perform such measurements. UE 220 may therefore use its capability report to indicate whether it supports CLI measurement and L3 CSI-RS measurement on the same symbol period. In some aspects, UE 220 may transmit otherwise convey the indication of its capability to support CLI and/or L3 RRM measurements during the symbol in a UE capability message, in a UE assistance information message, and the like.

In some aspects, the message used to convey the capability report of UE 220 may use the same capability defined for CLI measurement and PDCCH/PDSCH/CSI-RS for tracking/CSI-RS for CQI on the same symbol period. For example, UE 220 may transmit the message indicating the UE capability that includes a common indication for support for performing the L3 RRM measurement (e.g., the L3 CSI-RS measurement) and the CLI measurement during the symbol period. In some aspects, the common indication may include (e.g., may indicate support for) a common capability between support for L3 RRM measurement (e.g., the L3 CSI-RS measurement) and the CLI measurement during the symbol period and support for CLI measurement and reception of PDCCH/PDSCH/CSI-RS for tracking/CSI-RS for CQI during a second symbol period.

In some aspects, UE 220 may transmit the message indicating the UE capability using a capability for the support of CLI measurement and L3 CSI-RS measurement in the same symbol period. For example, UE 220 may transmit the message indicating the UE capability with an indication of support for performing the L3 measurement of FDM measurement resources during the symbol period, with the FDM measurement resources including resources for the CLI measurement and/or the L3 RRM measurement. The FDM measurement resources may correspond to a first frequency resource of the CLI measurement and a second frequency resource of the L3 RRM measurement.

Based on the UE capability indicated in the message transmitted to base station 205, UE 220 may perform the CLI measurement of CLI from one or more aggressor UEs (e.g., UE 215 and/or UE 225) and/or the L3 RRM measurements of RRM signals from base station 205 and/or one or more neighboring base stations (such as base station 210) during the symbol period. That is, if UE 220 determines that it does support performing the CLI and the L3 RRM measurements during the symbol period, UE 220 may perform the CLI measurement of CLI from aggressor UE (s) and the L3 RRM measurement of RRM signal (s) from base station 205 during the symbol period. Accordingly, UE 220 may transmit or otherwise convey measurement report to base station 205 indicating a result of performing the CLI measurement and the L3 RRM measurement. For example, the measurement report may include RSRP, RSSI, CQI, SINR, etc., associated with the CLI measurements and the L3 RRM measurements.

Conversely, UE 220 may determine that it does not support performing the CLI and the L3 RRM measurements during the same symbol period. In this situation, the capability reported by UE 220 to base station 205 may indicate that UE 220 does not support such measurements of CLI and L3 RRM resources during the same symbol period. Accordingly, when such collisions do occur during the symbol period, UE 220 may perform the CLI measurement or may perform the L3 RRM measurement during the symbol period. For example, UE 220 may identify a RSRP, RSSI, CQI, etc., for the CLI measurement or for the L3 RRM measurement and report this information in the measurement report transmitted to base station 205.

That is, in the situation where UE 220 does not support simultaneous CLI measurement and L3 RRM measurements (e.g., L3 CSI-RS measurement) in the same symbol, aspects of the described techniques provide different ways to determine which measurement is performed by UE 220. That is, as discussed above some wireless communication systems simply prioritize CLI measurements during the symbol period in which CLI measurement resources collide RRM measurement resources. However, aspects of the described techniques provide various mechanisms where the selection of CLI or L3 RRM measurements on the same symbol consider various other factors. For example, UE 220 may determine that the CLI measurement resources and the L3 RRM resources are configured for the same symbol period. In this situation, UE 220 may identify a measurement priority for performing measurements during the symbol period and perform the CLI measurements or the L3 RRM measurements during the symbol period according to the measurement priority.

In one option where UE 220 does not support simultaneous CLI and L3 RRM measurements, the measurement priority may be defined by the wireless communication system (e.g., in applicable standards) . That is, the relevant standards may indicate that the measurement priority gives priority to the CLI measurement or to the L3 RRM measurement, or vice versa, in the situation where CLI resources and RRM resources collide during the same symbol period. Accordingly, the network may configure UE 220 with the measurement priority favoring the L3 CSI-RS resource or the CLI measurement resource.

In another option where UE 220 does not support simultaneous CLI and L3 RRM measurements, the measurement priority may be defined by a base station 205. For example, base station 205 may transmit a message to UE 220 identifying or otherwise indicating a measurement priority to be applied in the situation where CLI measurement resources and L3 RRM measurement resources collide in the symbol period. Base station 205 may, via the measurement priority, prioritize the CLI measurement or the L3 RRM measurement in this situation. For example, base station 205 may consider previous measurement reports provided by UE 220 when determining the measurement priority to signal to UE 220. As one non-limiting, base station 205 may give preference to the CLI measurements when UE 220 is experienced CLI above a threshold, may give preference to the L3 RRM measurements when UE 220 is experiencing non-CLI interference above a threshold, and the like. Base station 205 may also consider such factors as network congestion levels, UE density, UE location, and the like, when determining which measurement to prioritize for UE 220. Accordingly, if UE 220 does not support simultaneous CLI measurements and L3 CSI-RS measurement on the same symbol, network may configure which measurement is to be performed by UE 220. The configuration can be based on RRC semi-static configuration, a MAC control element (CE) command and/or dynamically configured by DCI. In some aspects, the network may include a priority number in the CLI measurement resource and in the L3 CSI-RS measurement resource. UE 220 may receive and measure the resource with the priority number indicating higher priority than the other resource. In some aspects, an RRC message, MAC CE command, and/or DCI may carry an indication that indicates which of the CLI measurement resource and L3 CSI is prioritized.

In another option where UE 220 does not support simultaneous CLI and L3 RRM measurements, UE 220 may indicate its preferred measurement priority. In some aspects, this may include UE 220 transmitting an indication of the measurement preference for performing measurements during the symbol period. The indication may be transmitted in a UE capability message and/or a UE assistance information message. Accordingly, if UE 220 does not support simultaneous CLI measurement and L3 CSI-RS measurements in the same symbol, UE 220 may report is preferred measurement to the network in an uplink message. In some aspects, UE 220 may update its measurement preference for transmitting additional UE assistance information message (s) to base station 205. UE 220 may determine its measurement priority based on instantaneous and/or averaged CLI measurements, RRM measurements, interference levels, throughput rates, congestion levels, traffic patterns, and the like. Accordingly, UE 220 may identify and indicate its measurement preference to base station 205 according to its observed interference and/or channel performance metrics.

Accordingly, UE 220 may, according to the described techniques, identify and report its capability to support simultaneous measurement of CLI resources and L3 RRM resources configured in the same symbol to base station 205. When such simultaneous measurements are supported, UE 220 may, when CLI and RRM measurement resources collide in a symbol, perform both measurements and transmit a measurement report (e.g., CSI report) to base station 205 indicating the results of each measurement. When such simultaneous measurements are not supported, UE 220 may, when CLI and RRM measurement resources collide in the symbol, perform the CLI measurement or the L3 RRM measurement based on the measurement priority, and transmit the measurement report to base station 205 indicating the result of the selected measurement.

FIGs. 3A and 3B illustrate examples of a timing diagram 300 that supports handling of CLI collisions with reference signal measurements in accordance with aspects of the present disclosure. In some examples, timing diagram 300 may implement aspects of wireless communication systems 100 and/or 200. Aspects of timing diagram 300 may be implemented at or may be implemented by a base station and/or UE, which may be examples of the corresponding devices described herein.

As discussed above, aspects of the described techniques may include a UE identifying its capability to support simultaneous CLI and L3 RRM measurements during the same symbol period. For example, CLI measurement resources and L3 RRM measurement resources may be configured for the same symbol period. Some UEs may support simultaneous measurements of both measurement resources during the symbol period, while other UEs may not support such simultaneous measurements. The UE may transmit or otherwise convey an indication of its capability to support such measurements to its serving base station. In the situation where the UE support simultaneous CLI and L3 RRM measurements during the same symbol period, the UE may perform both measurements when CLI and L3 RRM measurement resources collide in the symbol period and report the results of the measurements to its serving base station in a measurement report. In the situation where the UE does not support simultaneous CLI and L3 RRM measurements in the same symbol period, the UE may perform the CLI measurement or the L3 RRM measurement during the symbol period and report the results of that measurement to its serving base station in the measurement report.

Moreover, aspects of the described techniques also provide mechanisms to be adopted to address the situation where a UE does not support such simultaneous measurements, but determines that such measurement resources collide during the symbol period. For example, the UE may perform the CLI measurement or the L3 RRM measurement based on a measurement priority that is adopted by the wireless communication system (e.g., in the relevant standards) , signaled by the serving base station, and/or based on a measurement preference of the UE indicated to its serving base station.

In some aspects, there may be a timing difference between CLI resources and RRM measurement resources (e.g., the serving cell and/or neighboring cell (s) downlink channel/signal, such as the CSI-RS) . For example, due to the propagation delay between an aggressor UE and its serving base station, an uplink signal transmitted by the aggressor UE at time t0 may be received at its serving base station at time t1. However, the aggressor UE may be located close enough to (e.g., proximate to) the victim UE such that the propagation delay for the uplink signal is negligible. Accordingly, the uplink signal transmitted by the aggressor UE may be received at the victim UE essentially just after time t0 (e.g., with minimal or no propagation delay) . This may create the situation where CLI measurement resources may not necessarily be time aligned with RRM measurement resources, or vice versa.

That is, the receive timing of CLI measurement resources may be ahead of the receive timing of downlink channel/signals from the serving base station and/or neighboring base station (s) . Therefore, when the CLI measurement is configured in downlink symbol N, the measurement actually partially overlap with symbol (s) of the L3 CSI-RS measurement resource around the downlink symbol N.

Accordingly, aspects of the described techniques provide various mechanisms to address such timing differences. As such timing differences may be based on the physical separation between the aggressor UE and the victim UE, such timing issues may span one or more symbols on either side of the symbol in which the victim UE is performing the measurement. The number of symbols on either side of the symbol in which the victim UE is performing the measurement may be based on the frequency range, subcarrier spacing, channel delay spread, and the like.

For example and referring to timing diagram 300-a of FIG. 3A, the victim UE may determine to perform the CLI measurement during the symbol period (e.g., downlink symbol N 325) . That is, the victim UE may determine that it does not support simultaneous CLI and L3 RRM measurements during a same symbol period. Accordingly, measurement priority may give preference to the CLI measurement. The CLI measurement resource may be configured for the downlink symbol N 325, e.g., aggressor UE (s) will transmit CLI reference signal during downlink symbol N 325 for victim UE (s) to perform CLI measurements.

However, timing alignment between the symbol period in which the CLI measurement is to be performed may be out of sync with respect to the timing alignment for the serving base station of the victim UE. For example, the timing synchronization of the victim UE with respect to its serving base station may include downlink symbol N-2 305, downlink symbol N-1 310, downlink symbol N 315, and downlink symbol N+1 320. In some aspects, downlink symbol N-1 310 and downlink symbol N 315 may be configured with L3 RRM measurement resources (e.g., L3 CSI-RS transmissions) for the UE to perform L3 RRM measurements. However, as the victim UE may not support simultaneous measurement of the CLI measurement resources and the L3 RRM measurement resources, the victim UE may refrain from performing the L3 RRM measurements during one or more symbol periods before the symbol period during which the CLI measurement is performed and/or after the symbol period during which the CLI measurement is performed. In this example, this may include the victim UE refraining from performing the L3 RRM measurements of the RRM measurement resources configured for downlink symbol N-1 310 and for downlink symbol N 315. Accordingly, if the victim UE does not support simultaneous CLI measurement and L3 CSI RS measurement on the same symbol, and if the UE determines to perform the CLI measurement, the victim UE may not receive the L3 CSI-RS resource a number of symbols before and/or after the OFDM symbol used for the CLI measurement. Conversely, when the L3 RRM measurement resources configured in downlink symbol N, the measurement may partially overlap with at least two (or more) adjacent symbols configured for CLI measurements.

In another example and referring to timing diagram 300-b of FIG. 3B, the victim UE may determine to perform the L3 RRM measurement during the symbol period (e.g., downlink symbol N 350 and/or during downlink symbol N+1 355) . That is, the victim UE may determine that it does not support simultaneous CLI and L3 RRM measurements during a same symbol period. Accordingly, measurement priority may give preference to the L3 RRM measurement. The L3 RRM measurement resource may be configured for the downlink symbol N 350 and again during the downlink symbol N+1 355, e.g., the serving base station will transmit reference signals (e.g., CSI-RS) during downlink symbol N 350 and/or downlink symbol N+1 355 for the UE to perform L3 RRM measurements.

However, timing alignment between the symbol period in which the L3 RRM measurement is to be performed may be out of sync with respect to the timing alignment for CLI measurement resources. For example, the timing synchronization of the victim UE with respect to its serving base station may include downlink symbol N-2 330, downlink symbol N-1 335, downlink symbol N 340, and downlink symbol N+1 345. In some aspects, downlink symbol N 340 may be configured with CLI measurement resources (e.g., CLI reference signal (RS) transmissions) . However, as the victim UE may not support simultaneous measurement of the CLI measurement resources and the L3 RRM measurement resources, the victim UE may refrain from performing the CLI measurements during one or more symbol periods before the symbol period during which the L3 RRM measurement is performed and/or after the symbol period during which the L3 RRM measurement is performed. In this example, this may include the victim UE refraining from performing the CLI measurements of the CLI measurement resources configured for downlink symbol N 340. Accordingly, if the victim UE does not support simultaneous CLI measurement and L3 CSI RS measurement on the same symbol, and if the UE determines to perform the L3 CSI-RS measurement, the victim UE may not receive the CLI measurement resource a number of symbols before and/or after the OFDM symbol used the L3 RRM measurement (s) . Accordingly, the victim UE may perform the L3 RRM measurement during downlink symbol N 350 and during downlink symbol N+1 355 and report the measurement results in the measurement report transmitted to its serving base station.

FIG. 4 illustrates an example of a process 400 that supports handling of CLI collisions with reference signal measurements in accordance with aspects of the present disclosure. In some examples, process 400 may implement aspects of wireless communication systems 100 and/or 200, and/or timing diagram 300. Aspects of process 400 may be implemented at and/or implemented by base station 405, UE 410, and UE 415, which may be examples of the corresponding devices described herein. In some aspects, base station 405 may be a serving base station of UE 410 and, in some examples, UE 415. In other examples, UE 415 may be associated with a different serving base station. In some aspects, UE 415 may be an aggressor UE in terms of CLI for UE 410 (which would be considered the victim UE in this situation) .

At 420, UE 410 may identify or otherwise determine its capability to support CLI measurement on a first frequency resource of a symbol and a L3 RRM measurement on a second frequency resource of the symbol period. That is, the CLI measurement resource may be FDM with the L3 RRM measurement resource during the symbol period. In some aspects, this may be based on UE 410 being able to implement separate FFT windows for performing the CLI measurements and L3 RRM measurements during the symbol period.

At 425, UE 410 may transmit (and base station 405 may receive) a message indicating the identified capability of UE 410. For example, the message may indicate that UE 410 does support or does not support performing the CLI measurement and the L3 RRM measurement during the symbol period. The message may include a UE capability message and/or a UE assistance information message. In some aspects, the message indicating the UE capability may include a common indication of support for performing L3 RRM measurement and the CLI measurement during the symbol period. In some aspects, the message indicating the UE capability may include an indication of support for performing L3 measurements of FDM measurement resources during the symbol period (e.g., the CLI measurement resources FDM with respect to the L3 RRM measurement resources) .

At 430, UE 410 may perform, during the symbol period and based on the capability indicated in the message, the CLI measurement of CLI (e.g., using CLI RS (s) ) from one or more aggressor UEs (e.g., with a single aggressor UE 415 being shown by way of example only) and/or the L3 RRM measurement of one or more RRM signals (e.g., CSI-RS) transmitted from base station 405.

For example, if UE 410 determines and signals that the capability of UE 410 does not support performing the CLI measurement and the L3 RRM measurement during the symbol period, UE 410 may determine that the CLI measurement resource and the RRM measurement resource are scheduled during the symbol period. In this situation, UE 410 may identify or otherwise determine a measurement priority for performing measurements during the symbol period and perform the CLI measurement or the L3 RRM measurement according to the measurement priority. As discussed, the measurement priority may be configured as part of the wireless communication system (e.g., fixed in the relevant standards) , may be signaled from base station 405 (e.g., using RRC configuration signaling, a MAC CE command, and/or a DCI) , and/or may be based on a measurement preference of UE 410 signaled to base station 405. For example, UE 410 may transmit an indication of its measurement preference to base station 405 in a UE capability message and/or a UE assistance information message. UE may select the CLI measurement or the L3 RRM measurement performed during the symbol period according to the measurement priority.

For example, if UE 410 determines and signals that the capability of UE 410 does support performing CLI measurement and the L3 RRM measurement during the symbol period, UE 410 may perform both the CLI measurement and the L3 RRM measurement during the symbol period.

At 435, UE 410 may transmit (and base station 405 may receive) a measurement report indicating a result of performing the CLI measurement and/or the L3 RRM measurement during the symbol period. That is, if UE 410 supports simultaneous CLI and L3 RRM measurements during the symbol period, the measurement report (e.g., a feedback message) may indicate the results of the CLI measurement and the L3 RRM measurement. If UE 410 does not support simultaneous CLI and L3 RRM measurements during the symbol period, the measurement report may indicate the results of the CLI measurement or the L3 RRM measurement.
