Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for measuring and reporting cross-link interference (CLI), where the configuration may indicate an interval duration between a CLI reference resource and a CLI report transmission by the UE. The CLI reference resource may indicate to the UE a point at which the UE is to cease CLI measurements, and indicate the start of the interval duration. The UE may measure CLI resources up to the occurrence of the CLI reference resource, at which point, the UE may refrain from measuring and start to generate a CLI report. The UE may generate the CLI report in accordance with the configuration and may include CLI measurements made prior to or during the CLI reference resource. The UE may transmit, to the base station, the CLI report at an end of the interval duration.

Description

TECHNIQUES FOR CROSS-LINK INTERFERENCE MEASUREMENT AND REPORTING

FIELD OF TECHNOLOGY

The following relates to wireless communications, including techniques for cross-link interference (CLI) measurement and reporting.

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) .

In some wireless communications systems, uplink signals transmitted by an aggressor user equipment (UE) may interfere with downlink signals received by a victim UE, thereby resulting in cross-link interference (CLI) at the victim UE. In some cases, a UE may be configured to measure and report CLI. Conventional techniques for CLI measurement and reporting may be deficient.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for cross-link interference (CLI) measurement and reporting. Generally, the described techniques provide for CLI measurement and reporting by a UE, such as layer 1 (L1) CLI measurement and reporting. A UE may be configured with one or more parameters associated with measuring and reporting L1 CLI. For example, a UE may receive and/or identify a configuration for measuring and reporting CLI, where the configuration may indicate an interval duration between a CLI reference resource and a CLI report transmission by the UE. The CLI reference resource may indicate to the UE a point at which the UE is to cease CLI measurements, and indicate the start of the interval duration. In some cases, at the end of the interval duration, the UE may transmit the CLI report. As such, the UE may measure CLI resources up to the occurrence of the CLI reference resource, at which point, the UE may refrain from measuring and start to generate a CLI report. The UE may generate the CLI report in accordance with the configuration and may include CLI measurements made prior to or during the CLI reference resource. The UE may transmit, to the base station, the CLI report at an end of the interval duration.

DETAILED DESCRIPTION

In some wireless communications systems, multiple nearby UEs may communicate with a base station (or different base stations) via either uplink signaling or downlink signaling. In some cases, whether a UE is communicating via uplink signaling or downlink signaling may be based on a current time-domain location (e.g., a current symbol) in a slot and a corresponding slot format configured at the UE. For example, a first UE may be configured with a first slot format and a second UE may be configured with a second slot format such that the first UE may communicate with a base station via uplink signaling or downlink signaling according to the first slot format while the second UE may communicate with the base station (or a different base station) via uplink signaling or downlink signaling according to the second slot format. In some cases, the first slot format may differ from the second slot format such that the first UE may be scheduled for downlink signaling over the same symbols as the second UE is scheduled for uplink signaling. In such cases, the transmission of the uplink signaling from the second UE may interfere with the downlink signaling received by the first UE. Such interference from one UE to another may be referred to as cross-link interference (CLI) . To account for CLI between the first UE and the second UE, the base station may configure a time-domain resource as a measurement resource (e.g., a CLI measurement resource) over which the first UE may measure CLI.

In some cases, the base station may configure the CLI measurement at the first UE as a Layer 3 (L3) measurement, which may result in a long-term view of the CLI conditions at the first UE. In examples in which the slot formats at the first UE and the second UE are configured dynamically (e.g., by downlink control information (DCI) ) , however, the time-domain resources over which CLI may be present at the first UE may change in the short-term. For example, if the slot formats at the first UE or the second UE, or both, are dynamically configured, the CLI measurement resource may no longer include symbols allocated for downlink signaling to the first UE and uplink signaling from the second UE (e.g., when CLI may likely occur) . As such, the first UE may sub-optimally measure the actual CLI at the first UE because the configuration of the L3 CLI measurement may be unable to keep up (e.g., stay current) with the dynamically configured slot formats and may lose synchronization with the symbols during which CLI may be likely.

To improve flexibility and reliability in the network, the UE may be configured to perform layer 1 (L1) CLI measurement and reporting. To facilitate L1 measurement and reporting, a UE may be configured with one or more parameters associated with measuring and reporting L1 CLI. In some cases, the one or more parameters may indicate the resources associated with a CLI reference resource, a position of a CLI reference resource, a duration between the CLI reference resource and a CLI reporting resource, etc. For example, a UE may receive and/or identify a configuration for measuring and reporting CLI, where the configuration may indicate an interval duration between a CLI reference resource and a CLI report transmission by the UE. The CLI reference resource may indicate to the UE a point at which the UE is to cease CLI measurements, and indicate the start of the interval duration. In some cases, at the end of the interval duration, the UE may transmit the CLI report. As such, the UE may measure CLI resources up to the occurrence of the CLI reference resource, at which point, the UE may refrain from measuring and start to generate a CLI report. The UE may generate the CLI report in accordance with the configuration and may include CLI measurements made prior to or during the CLI reference resource. The UE may transmit, to the base station, the CLI report at an end of the interval duration.

Particular aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in CLI measurement and reporting by decreasing latency, improving flexibility, and improving reliability among other advantages. As such, supported techniques may include improved network operations and, in some examples, may promote network efficiencies, among other benefits.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects are then described with respect to CLI reporting configurations and a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for CLI measurement and reporting.

FIG. 1 illustrates an example of a wireless communications system 100 that supports techniques for CLI measurement and reporting 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.

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.

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.

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 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.

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 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.

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 UE 115 may be configured with one or more parameters associated with measuring and reporting CLI. In some cases, the UE 115 may be configured to measure L1 CLI metrics and transmit an L1 CLI report. For example, a UE 115 may receive and/or identify a configuration for measuring and reporting CLI, where the configuration may indicate an interval duration between a CLI reference resource and a CLI report transmission by the UE 115. The CLI reference resource may indicate to the UE 115 a point at which the UE 115 is to cease CLI measurements and indicate the start of the interval duration. In some cases, at the end of the interval duration, the UE 115 may transmit the CLI report. As such, the UE 115 may measure CLI resources up to the occurrence of the CLI reference resource, at which point, the UE 115 may refrain from measuring and start to generate a CLI report. The UE 115 may start to generate the CLI report at any point during the interval duration. The UE 115 may generate the CLI report in accordance with the configuration and may include CLI measurements made prior to or during the CLI reference resource. The UE 115 may transmit, to the base station 105, the CLI report at an end of the interval duration.

FIGs. 2A and 2B illustrate example

wireless communications systems

200 and 201, respectively, that support techniques for CLI measurement and reporting in accordance with aspects of the present disclosure. In some examples, the

wireless communications systems

200 and 201 may implement aspects of the wireless communications system 100. The

wireless communications systems

200 and 201 may each include multiple UEs 115 and one or more base stations 105, which may be examples of corresponding devices described herein. The wireless communications system 200, as shown in FIG. 2A, may illustrate implementations of the present disclosure in examples in which nearby UEs 115 communicate with different base stations 105. The wireless communications system 201, as shown in FIG. 2B, may illustrate implementations of the present disclosure in examples in which nearby UEs 115 may communicate with the same base station 105. In both FIG. 2A and FIG. 2B, a base station 105 and one or more UEs 115 may each be configured to support L1 CLI measurement and reporting.

For example, a first UE 115, such as a UE 115-a (as shown in the wireless communications system 200) or a UE 115-c (as shown in the wireless communications system 201) , may experience CLI 210 (e.g., CLI 210-a, or CLI 210-b, respectively) from a second UE 115, such as a UE 115-b (which may be nearby or proximate to the UE 115-a) or a UE 115-d (which may be nearby or proximate to the UE 115-c) , in cases in which the network (e.g., a base station 105) has configured different TDD uplink and downlink slot formats for the first UE 115 and the second UE 115. For instance, as shown in the wireless communications system 200, the UE 115-a may communicate with a base station 105-a over a communication link 205-a within a geographic area 110-a and the base station 105-a may configure a first slot format at the UE 115-a. Likewise, the UE 115-b may communicate with a base station 105-b over a communication link 205-b within a geographic area 110-b and the base station 105-b may configure a second slot format at the UE 115-b.

Similarly, as shown in the wireless communications system 201, the UE 115-c may communicate with a base station 105-c over a communication link 205-c within a geographic coverage area 110-c and the base station 105-c may configure a first slot format at the UE 115-c. Likewise, the UE 115-d may communicate with the base station 105-c over a communication link 205-d within the geographic coverage area 110-c and the base station 105-c may configure a second slot format at the UE 115-d. In some cases, the base station 105-c may have a full-duplex capability or functionality. In some aspects, the configured slot formats may include one or more uplink symbols 215, one or more downlink symbols 220, or one or more flexible symbols, or any combination thereof, such that the UEs 115 may communicate with their respective base stations 105 via either uplink signaling or downlink signaling according to their respectively configured slot formats.

In some cases, the first slot format may be different than the second slot format such that, when aligned in the time-domain, the location of uplink symbols 215 or downlink symbols 220 in the first slot and the location of uplink symbols 215 or downlink symbols 220 in the second slot format may be different (e.g., non-overlapping) . For example, at a time- domain location, the first slot format configured at the UE 115-a or the UE 115-c may include one or more downlink symbols 220 (e.g., downlink symbols 220-a, and 220-b, respectively) and the second slot format configured at UE 115-b or UE 115-d may include one or more uplink symbols 215 (e.g., uplink symbols 215-a, and 215-b, respectively) . As such, at the time-domain location, the UE 115-b or the UE 115-d may transmit signaling to the base station 105-b or to the base station 105-c, respectively, via communication links 205-b and 205-d, respectively. At or near the same time-domain location, UE 115-a or UE 115-c may receive signaling from the base station 105-a or from the base station 105-c, respectively via communication links 205-a and 205-c, respectively. In some cases, one or more transmissions by UE 115-b while UE 115-a is receiving may generate CLI 210-a at UE 115-a, which may decrease the likelihood of UE 115-a to successfully receive downlink signaling from the base station 105-a. Similarly, one or more transmissions by UE 115-d while UE 115-c is receiving may generate CLI 210-b at UE 115-c, which may lower the likelihood of UE 115-c to successfully receive signaling from the base station 105-c. In other words, CLI 210 may arise at UE 115-a or UE 115-c from one or more uplink transmissions from UE 115-b or UE 115-d, respectively, during a downlink-designated symbol at UE 115-a or UE 115-c. For example, UE 115-a or UE 115-c may experience interference from UE 115-b or the UE 115-d as CLI 210-a or CLI 210-b, respectively. As such, UE 115-b and UE 115-d may be referred to as aggressor UEs 115 and UE 115-a and UE 115-c may be referred to as victim UEs. CLI 210-a may be referred to as inter-cell CLI 210, and CLI 210-b may be referred to as intra-cell CLI 210.

To account for such CLI 210 at a first UE 115 (e.g., either or both of UE 115-aand UE 115-c) , the base station 105 serving the first UE 115 may configure the first UE 115 to measure CLI 210 from an aggressing second UE 115 (e.g., either or both of the UE 115-b and the UE 115-d) . As such, the second UE 115 may be unaware that the first UE 115 is measuring uplink transmissions of the second UE 115 and may accordingly refrain from transmitting signaling (such as a reference signal) to the first UE 115 that is dedicated for CLI 210 measurement at the first UE 115. In some cases, the base station 105 serving the first UE 115 may configure measurement of CLI 210 at the first UE 115 as an L3 measurement, which may be similar to radio resource measurement (RRM) for mobility in a multi-cell scenario. For example, base station 105-a may configure UE 115-a with a CLI measurement resource (which may be configured as a periodic resource via radio resource control (RRC) signaling) over which UE 115-b may transmit a sounding reference signal (SRS) or other uplink transmissions such as physical uplink control channel (PUCCH) , a physical uplink shared channel (PUSCH) , and a random access channel (RACH) preamble to base station 105-b. In such examples, UE 115-a may measure a reference signal received power (RSRP) based on the SRS or the received signal strength indicator (RSSI) that corresponds to the uplink transmissions from the UE 115-b over the periodic CLI measurement resource. Although referred to as an interference, base station 105-a may indicate the CLI measurement resource as an indication of an uplink transmission from UE 115-b that may generate CLI 210-a at the UE 115-a. Whether UE 115-a experiences CLI 210 may be based on whether UE 115-a receives downlink signaling from the base station 105-a in resources that overlap with the uplink transmission from UE 115-b. Base station 105-c may configure a similar CLI measurement resource at UE 115-c.

Such a configuration of a CLI measurement resource over which UE 115-a or UE 115-c may measure the CLI 210 may be suitable for estimating a long-term average of the CLI 210 from an uplink transmission of an aggressor UE 115. For example, based on using an L3 measurement of the CLI 210, UE 115-a may determine a long-term view of the CLI 210-a condition at UE 115-a. Similarly, UE 115-c may determine a long-term view of the CLI 210-b condition at UE 115-c. In some cases, however, such a configuration of a CLI measurement resource over which to measure a long-term average of the CLI 210 at UE 115-a or UE 115-c may be sub-optimal. For instance, in cases in which dynamic TDD configuration (e.g., dynamic slot format configuration) is enabled for the UEs 115, an L3 measurement resource of the CLI 210 at UE 115-a and UE 115-c may be unable to stay current with the actual symbols over which UE 115-b or UE 115-d may transmit uplink signaling and over which UE 115-a or UE 115-c may receive downlink signaling.

In some examples, UE 115-a or UE 115-c may use a L1 (e.g., physical layer, higher layer) measurement to measure the CLI 210 and may use L1 reporting of a CLI measurement report. In some cases, a different layer may be used. To facilitate the L1 CLI measurements and report, the UE 115 may be configured, such as by a base station 105, with report settings and resource settings that may indicate one or more parameters associated with L1 measurement and reporting. For example, a UE 115 may be configured with report, where in some cases, report settings may be configured for a UE 115 which is associated with a single downlink bandwidth part (BWP) . The report setting may include information (e.g., parameters) for the UE 115 to measure and report CLI 210. In some cases, one of the parameters may include report quality. In some cases, the report setting may indicate that the CLI report is aperiodic, periodic, or semi-persistent. As such, the CLI measurement resource may coincide with the CLI report type. For example, an L1 CLI measurement resource may be configured as periodic (e.g., via RRC configuration) , semi-persistently scheduled (e.g., via RRC configuration with DCI activation) , or as aperiodic (e.g., triggered by a one-time DCI) . Additionally or alternatively, the UE 115 may be configured with resource settings, where one or more resource set types may be configured by a single report setting. In some cases, a resource set type may include a non-zero-power (NZP) based resource, or a zero-power (ZP) based resource, or both. A resource configuration indicated by the resource setting may indicate the time and/or frequency resources where the measurement resource (e.g., CLI resource) may be received by the UE 115. In some cases, the resource configuration may indicate time domain periodicity (e.g., how frequently a CLI resource may occur) and/or offset for the CLI resource.

To enable a reliable CLI measurement and reporting scheme (e.g., for L1 CLI measurement and reporting) , one or more timeline parameters may be configured for the UE 115 to determine when to transmit the CLI report. In some cases, the one or more timeline parameters may indicate the resources associated with a CLI reference resource, a position of a CLI reference resource, a duration between the CLI reference resource and a CLI reporting resource, a duration between a physical downlink control channel (PDCCH) and a PUSCH, a duration between a CLI resource and a PUSCH, etc. For example, a UE 115 may identify a configuration for measuring and reporting CLI, where the configuration may indicate an interval duration between a CLI reference resource and a CLI report transmission by the UE 115. In some cases, the UE 115 may have received the configuration from a base station 105. The CLI reference resource may indicate to the UE 115 a point at which the UE 115 is to cease CLI measurements, and indicate the start of the interval duration. In some cases, at the end of the interval duration, the UE 115 may transmit the CLI report. As such, the UE 115 may measure CLI resources up to the occurrence of the CLI reference resource, at which point, the UE 115 may refrain from measuring and start to generate a CLI report at some point during the interval duration. The UE 115 may generate the CLI report in accordance with the configuration and may include CLI measurements made prior to or during the CLI reference resource. The UE 115 may transmit, to the base station 105, the CLI report at an end of the interval duration.

FIG. 3 illustrates an example of a CLI reporting configuration 300 that supports techniques for CLI measurement and reporting in accordance with aspects of the present disclosure. The CLI reporting configuration 300 may be implemented by a base station and a UE, which may be examples of a base station 105 and a UE 115 as described with reference to FIGs. 1 and 2. In some cases, a base station may configure the CLI reporting configuration 300 which may be utilized by a UE to perform a CLI measurement and reporting procedure. Additionally or alternatively, other wireless devices, such as a UE, may configure the CLI reporting configuration 300, and other devices, such as a base station, may utilize the CLI reporting configuration 300.

To enable reliable CLI measurement and reporting, a UE may receive (e.g., from a base station, or other network device) , identify, and/or perform a CLI reporting configuration 300. The CLI reporting configuration 300 may include at least one CLI resource 305 that the UE may use to measure CLI from one or more aggressor UEs. The CLI reporting configuration 300 may include a CLI reference resource 310, a CLI report 320, and a reference interval 315 (e.g., interval duration) . The CLI reference resource 310 may be configured to define an anchor (e.g., baseline, starting point) associated with the reference interval 315. In some cases, the UE may receive the time and/or frequency location of the CLI reference resource 310 prior to the occurrence of the CLI reference resource 310. For example, the UE may receive or be pre-configured with a configuration associated with CLI measurement and reporting. In some cases, the configuration may include an indication of the location (e.g., time and/or frequency location) of one or more CLI resources 305, an indication of the location of one or more CLI reference resources 310, an indication of one or more reference intervals 315 associated with the one or more CLI reference resources 310. In some cases, the UE may receive the configuration in one message, or multiple different messages from a base station or some other network device. In some cases, the UE may dynamically identify the occurrence of the CLI reference resource 310 without prior knowledge of the location of the CLI reference resource 310 and the UE may perform the CLI reporting procedure based on dynamically identifying the CLI reference resource 310, where the duration reference interval 315 may be pre-configured, or may be signaled to the UE (such as in a periodic or semi-persistent configuration message) .

As such, a UE may be configured with one or more CLI resources 305 for the UE to measure CLI metrics (e.g., RSRP, RSSI) , where the CLI measurements may be fast (e.g., instantaneous, near instantaneous) measurements due to the measurements being L1 measurements. Upon identifying the occurrence of a CLI reference resource 310, the UE may refrain from continuing to measure CLI resources 305, even if a CLI resource 305 is allocated after the CLI reference resource 310. The CLI reference resource 310 may coincide (e.g., fully or partially overlap) with a CLI resource 305. In such cases, the UE may be configured to refrain from measuring this CLI resource 305 that overlaps with the CLI reference resource 310. Alternatively, the UE may be configured to measure this CLI resource 305 that overlaps with the CLI reference resource 310, and to refrain from measuring any CLI resources 305 after the CLI reference resource 310.

The CLI reference resource 310 may be configured as a set of time and/or frequency resources. For example, in the frequency domain the CLI reference resource 310 may be defined by a group of downlink physical resource blocks. In some cases, the group of downlink physical resource blocks may correspond to the frequency band to which the derived CLI measurements relate. Such that the frequency band the UE measures the CLI measurements in may be the same frequency band in which the CLI reference resource 310 is located. In the time domain, the CLI reference resource 310 may be defined one or more downlink time resources (e.g., slots, symbols, TTIs) . For example, the CLI reference resource 310 may be defined as a single downlink slot.

Upon identifying the occurrence of the CLI reference resource, the UE may identify that the reference interval 315 has started, and that the UE has the remainder of the reference interval 315 to generate a CLI report. The expiry of the reference interval 315 may serve as a trigger for the UE to transmit the CLI report. In some cases, the reference interval 315 may be defined in relation to a quantity of time units, such as a number of slots (e.g., n_ref slots) , subframes, TTIs, etc. In some cases, the reference interval may be defined in terms of a duration of time, such as a number of milliseconds (e.g., n_ref ms) , seconds, etc.

In some cases, the length of the reference interval 315 may be based on the report type of the CLI report, or based on the number of CLI resources 305 the UE is configured to measure prior to the CLI reference resource 310. The duration of the reference interval 315 may be determined such that the CLI reference resource 310 and/or the CLI report 320 is located in a valid downlink slot. As such, if the UE is configured to measure a single CLI resource 305 to generate a periodic or semi-persistent CLI report 320, the reference interval 315 duration may be smaller than if the UE is configured to measure multiple CLI resources 305. In some cases, the additional time allocated for the multiple CLI resources 305 may be used by the UE to generate a more complex and/or larger CLI report 320. For example, a UE that is configured to measure a single CLI resource 305 may be configured with a reference interval 315 of 4 ms, and a UE that is configured to measure multiple CLI resources 305 may be configured with a reference interval 315 of 5 ms. If the UE is configured to measure and report CLI aperiodically, the reference interval 315 may be based on a parameter (e.g., Z’) which may correspond to the symbol number indicated in a higher layer delay requirement, or may be pre-defined. In some cases, the reference interval 315 defined for an aperiodic CLI report may be the smallest value greater than or equal to

where

may refer to the number of symbols that are configured to fit into a slot.

In some cases, if the UE is not configured with a valid downlink slot for the CLI reference resource 310 that corresponds to a CLI report setting (e.g., in a serving cell) , CLI reporting may be omitted (e.g., for that serving cell) in corresponding uplink slot. For example, if the UE is not configured with a downlink slot that fits within a configured CLI reporting configuration, then the UE may not transmit a CLI report 320. In some implementations, a CLI report configuration may be reconfigured (via CLI report settings, CLI resource settings) , or one or more other communication parameters may change and impact the CLI report configuration. In such cases, after a CLI report 320 is reconfigured, after a serving cell activation, after a BWP change, or after activation of semi-persistent CLI report procedure, or a combination thereof the UE may transmit a CLI report 320 after receiving at least one CLI resource transmission occasion, where the CLI resource transmission occasions may occur no later than CLI reference resource 310. If the CLI resource transmission occasion occurs later than the CLI reference resource 310, the UE may refrain from transmitting (e.g., drop) the CLI report 320.

In some cases, the CLI resources 305 may be non-zero power (NZP) CLI resources 305, or zero-power (ZP) CLI resources 305. The UE may typically be configured with NZP CLI resources 305 if the UE is experiencing intra-cell CLI, as described with reference to FIG. 2B, and the UE may typically be configured with ZP CLI resources 305 if the UE is experiencing inter-cell CLI, as described with reference to FIG. 2A. In some case, the UE may experience both intra-cell and inter-cell CLI. The UE may be configured to assume that a ZP CLI resource 305 and an NZP CLI resource 305 will not overlap.

FIG. 4 illustrates an example of a CLI reporting configuration 400 that supports techniques for CLI measurement and reporting in accordance with aspects of the present disclosure. The CLI reporting configuration 400 may be implemented by a base station and a UE, which may be examples of a base station 105 and a UE 115 as described with reference to FIGs. 1 and 2. In some cases, a base station may configure the CLI reporting configuration 400 which may be utilized by a UE to perform a CLI measurement and reporting procedure. Additionally or alternatively, other wireless devices, such as a UE, may configure the CLI reporting configuration 400, and other devices, such as a base station, may utilize the CLI reporting configuration 400.

Additionally or alternatively to being configured with a CLI reference resource, a UE may be configured with one or more other CLI timeline parameters. In some cases, the parameters that are configured and/or the parameters the UE considers may be based on the report type (e.g., periodic, semi-persistent, aperiodic) of the CLI report. For example, if the UE is configured with periodic or semi-persistent CLI reporting, the UE may use the CLI reference resource and reference interval to determine when to stop measuring CLI and to transmit the CLI report. In some cases, if the UE receives an indication for the UE to transmit an aperiodic CLI report, the UE may use the CLI reference resource, the reference interval, Z, or Z’, or a combination thereof. In some cases, if the UE receives an indication to transmit an aperiodic CLI report, the UE may use only Z and Z’ to measure and transmit CLI. In some cases, the indication to transmit an aperiodic CLI report may be a downlink control channel 405. For example, the UE may receive a downlink control channel 405, such as a PDCCH, that may trigger the UE to measure and report CLI, where the UE may report the CLI measurement in an uplink shared channel 415, such as a PUSCH. In some cases, the downlink control channel 405 may indicate the location of one or more CLI resources 410. In some cases, the CLI resource 410 depicted in FIG. 4 may coincide with a CLI reference resource. In such cases, or some other cases, the one or more other CLI timeline parameters may include Z and Z’ (this Z’ may be different from the Z’ as described with reference to FIG. 3) . Z may refer to a duration of time or number of time resources between the last symbol of the downlink control channel 405 (e.g., PDCCH) that triggers the aperiodic CLI report (e.g., or some other CLI report) and the first symbol of the uplink shared channel 415 (e.g., PUSCH) which carriers the CLI report (e.g., aperiodic CLI report) . The time duration may be a minimum OFDM symbol number gap. Z’ may refer to a duration of time or number of time resources between the last symbol of the CLI resource (e.g., aperiodic CLI resource) the UE may use to calculate the CLI report and the first symbol of the uplink shared channel 415 (e.g., PUSCH) . The time duration may be a minimum OFDM symbol number gap.

The values of Z and Z’ may be based on the reporting quantity (e.g., the number of CLI reports the UE is configured to transmit) . The values of Z and Z’ may be preconfigured, or dynamically or semi-persistently indicated. For example, the UE may receive an explicit indication of Z and/or Z’, such that the UE may receive the value of Z and/or Z’ such as in the downlink control channel 405, or some other message. In another example, the UE may receive an implicit indication of Z and/or Z’. In some cases, the implicit index may be an index. The UE may be configured with one or more lookup tables, where the UE may determine the values of Z and/or Z’ based on the index and the one or more look tables. In some cases, the UE may independently determine the value of Z and/or Z’ based on the look tables and the parameters associated with the CLI measurement and reporting procedure.

In some implementations, the UE may be configured with multiple lookup tables, where each lookup table corresponds a different configuration and each lookup table includes one or more sets of values for Z and Z’, where each set of values is associated with an index. For example, the UE may be configured with multiple different look tables, where each lookup table is associated with a different CLI computation delay requirement (or channel state information (CSI) computation delay requirement) . The computation delay requirements may be based on one or more CLI resource configurations. For example, the values of Z and Z’ may be based on the CLI resource 410 being a wideband resource and subband resource. Additionally or alternatively, the values of Z and Z’ may be based on a single CLI resource 410 being configured for a CLI report or multiple CLI resources being configured for a CLI report.

In a first case with a wideband and single resource configuration, if a single CLI report is triggered (by a PDCCH) , without multiplexing with either an uplink shared channel or feedback information (e.g., HARQ-ACK) and when all of the CPUs of the UE are unoccupied, the values of Z and Z’ may be determined in the lookup table associated with computation delay requirement 1. In a second case with a wideband and single resource configuration and/or a subband and single resource configuration, the values of Z and Z’ may be determined by Z ₁ and Z ₁’ in the lookup table associated with computation delay requirement 2. In a third case with a wideband and multiple resource configuration and/or a subband and multiple CLI resource configuration, the values of Z and Z’ may be determined by Z ₂ and Z ₂’ in the lookup table associated with computation delay requirement 2. In some cases, at least two lookup tables may be configured for computation delay requirement 2, where one is associated with Z ₁ and Z ₁’ and the other lookup table is associated with Z ₂ and Z ₂’. In some case, the values of Z and Z’ may generally be the lowest in the lookup table used in the first case, and may be the highest in the lookup table used in the third cases, comparatively. In some implementations, the value of Z may be updated one or more times. In such cases, the final value of Z may be the maximum value across the original or updated values.

As described with reference to FIGs. 2A and 2B, a UE may be configured with ZP-based CLI resources for inter-cell CLI measurements based on RSSI measurements, for example and may be configured with NZP-based CLI resources for intra-cell CLI measurements based on RSRP detection, for example. In some cases, the RSSI computation may be more simple than an RSRP computation. As such, the timing interval (e.g., minimum timing interval) for CLI RSSI measurements may be less than the timing interval (e.g., minimum timing interval) for CLI RSRP measurements. As such, the timing interval associated with a ZP CLI resource (e.g., the duration of the CLI resource) may be less than or equal to the timing interval associated with the NZP CLI resource.

FIG. 5 illustrates an example of a process flow 500 that supports techniques for CLI measurement and reporting in accordance with aspects of the present disclosure. The process flow 500 may illustrate an example CLI measurement and reporting scheme. For example, UE 115-e may perform measure and report, to base station 105-d, CLI caused by another UE 115. Base station 105-d and UE 115-e may be examples of the corresponding wireless devices described with reference to FIGs. 1 through 4. In some cases, instead of UE 115-e implementing the CLI measurement and reporting procedure, a different type of wireless device (e.g., a base station 105) may perform CLI related measurements. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.

At 505, base station 105-d may determine a configuration for at least UE 115-e to measure and report CLI.

At 510, UE 115-e may receive, from base station 105-d (or some other network device) , a configuration for measuring and reporting CLI, the configuration indicating an interval duration between a CLI reference resource and a CLI report transmission by the UE.

In some cases, UE 115-e may identify a location of the CLI reference resource, and refrain from measuring for CLI during the interval duration after the identified location of the CLI reference resource. For example, UE 115-e may measure CLI based on receiving CLI resources and upon identifying the occurrence of the CLI reference resource, UE 115-e may refrain from measuring CLI because the interval duration started at the beginning or at the end of the CLI reference resource. The CLI reference resource may include a downlink slot (or any number of downlink slots, symbols TTIs, seconds, milliseconds, etc. ) . In some implementations, the CLI reference resource includes a set of downlink physical resource blocks, where the set of downlink physical resource blocks may be associated with a frequency range of the CLI measurements.

UE 115-e may identify the interval duration from the configuration as a number of slots between the CLI reference resource and the CLI report. UE 115-e may identify the interval duration from the configuration as a duration of time between the CLI reference resource and the CLI report. In some cases, the interval duration is based on a number of CLI resources UE 115-e is configured to measure. In some cases, the interval duration is based on the CLI report being a periodic report, a semi-persistent report, or an aperiodic report. The interval duration may be based on UE 115-e experiencing and measuring intra-cell crosslink interference. The interval duration may be based on UE 115-e experiencing and measuring inter-cell CLI.

In some cases, UE 115-e may receive, such as from base station 105-d, a downlink control channel (e.g., PDCCH) that triggers UE 115-e to generate the CLI report. The downlink control channel may trigger UE 115-e to transmit the CLI report in an uplink shared channel (e.g., PUSCH) . UE 115-d may identify from the configuration, a first number of symbols (e.g., Z as described with reference to FIG. 4) defining a first minimum gap between a last symbol of the downlink control channel and a first symbol of the uplink shared channel, and UE 115-e may identify, from the configuration, a second number of symbols (e.g., Z’ as described with reference to FIG. 4) defining a second minimum gap between a last symbol of a CLI resource and the first symbol of the uplink shared channel. In some cases, UE 115-e may receive, in the configuration, an index from which values of the first number of symbols and of the second number of symbols are identified. UE 115-e may select a table for identification of the values of the first number of symbols and of the second number of symbols based on the index. UE 115-e may select the table based on a quantity of CLI reports the downlink control channel triggers or on the CLI resource being a wideband resource, a subband resource, or both. In some implementations, values of the first number of symbols and the second number of symbols are based at least in part on a quantity of CLI reports the downlink control channel triggers. In some implementations, values of the first number of symbols and the second number of symbols are based at least in part on the CLI resource being a wideband resource, a subband resource, or both.

At 515, UE 115-e may generate a CLI report in accordance with the configuration, the CLI report including CLI measurements made prior to or during the CLI reference resource. In some cases, UE 115-e may generate the CLI report during the interval duration to transmit the CLI report at the end of the interval duration.

At 520, UE 115-e may transmit, to base station 105-d, the CLI report at an end of the interval duration. In some implementations, UE 115-e may transmit the CLI via and L1 report. In some cases, UE 115-e may determine that there is not a CLI reference resource corresponding to the CLI report, and UE 115-e may refrain from transmitting the CLI report based on the determination.
