Technical Field

[0003] The following relates generally to wireless communications and, more particularly, to network-assisted self-measurement for achieving full-duplex operation. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able to support communication with multiple users by sharing 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, advanced LTE (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 use various 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 extended orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting the communication of multiple communication devices, which may be referred to as user equipment (UE) in addition.

[0005] A wireless device may operate in full-duplex mode, which may involve transmitting and receiving simultaneously and on the same resources. Full-duplex communication may result in self-interference (SI), where signals transmitted by the device may interfere with the device's reception of signals.

[0006] Overview

[0007] The described technology relates to improved methods, systems, devices and apparatuses that support network-assisted self-measurement for achieving full-duplex operation. In general, the described technology provides for reducing self-interference (SI) experienced at a user equipment (UE) by performing network-assisted self-measurement. The UE can transmit and receive signals in a full-duplex communication configuration. Since the signal transmitted by the UE at the transmit antenna array interferes with the signal reception by the UE at the receive antenna array, the UE may experience SI. In order to avoid and reduce SI, the UE can perform network-assisted self-measurement techniques. The UE can receive a measurement configuration from a second wireless device (such as a base station) to support full-duplex operation using shared resources. The UE can use a first antenna array of a first wireless device to transmit a first signal via a shared resource via a first transmission beam. The UE device can monitor the shared resource using a first receive beam via a second antenna array of the UE according to the measurement configuration. The UE can then transmit a measurement report to the second wireless device based on the monitoring. The base station can transmit a duplex configuration for configuring the full-duplex operation of the UE based on the measurement report to the UE.

[0083] Detailed Description

[0084] Some wireless communication systems may support full-duplex communication. Full-duplex communication may include simultaneous transmission and reception by a user equipment (UE) or another wireless device. Some systems may support full-duplex communication on the same sector and using the same time and frequency resources. In some cases, a base station or an integrated access and backhaul (LAB) node may include multiple sectors or cells. Different sectors or cells may typically use different architectures, such as having different antenna panels, radio frequency (RF) / intermediate frequency (IF) components, baseband processing units, etc.

[0085] Self-interference (SI) may exist in wireless communication systems that support full-duplex operation. SI may occur when a transmitted signal leaks or interferes with a receiver port. SI may also occur when a transmitted signal is reflected back to a receiver port, such as from an object. SI caused by such reflections from an object may be an example of a nuisance echo. A wireless device or base station may experience SI in many situations of beamforming communications. For example, SI may occur in a situation where the transmission of a transmit beam interferes with the reception of a receive beam.

[0086] SI can be reduced by spatial isolation of transmit and receive beams in a beamforming communication system. In some examples, spatial isolation can be used to reduce clutter echoes. Spatial isolation can include selecting beams for transmission and reception that have a lower likelihood of causing SI. SI can also be reduced by utilizing beam nulling, which can include sidelobe suppression. SI can also be reduced by performing SI cancellation in the analog or digital domain, or a combination of these techniques.

[0087] A wireless device (e.g., UE, base station, transmit / receive point (TRP), etc.) with multiple antenna arrays can use a first antenna array to transmit a signal using a transmission beam in a shared time or frequency resource (or both), and use a second antenna array to generate a measurement of the signal in the shared resource. The measurement can be an example of a self-measurement. The UE can use these measurements to select a transmit and receive beam pair that can reduce the SI at the UE. In some cases, the UE can autonomously generate these measurements and adjust its beams accordingly. In other cases, the UE can coordinate with a network device to determine which transmit and receive beams to use. In this case, the UE can transmit a measurement report to a network device (such as a base station). The base station can then configure the UE's full-duplex operation based on the measurement report and other information.

[0088] Aspects of the present disclosure are initially described in the context of wireless communication systems. Aspects of the present disclosure are subsequently described in the context of process flow diagrams. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to network-assisted self-measurement for implementing full-duplex operation.

[0089] Figure 1 An example of a wireless communication system 100 supporting network-assisted self-measurement for implementing full-duplex operation according to various aspects of the present disclosure is illustrated. The wireless communication 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 communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication 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.

[0090] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may be different forms of devices or devices with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly 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 stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support signal communication according to one or more radio access technologies.

[0091] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be different forms of devices or devices with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, IAB nodes, or other network equipment), such as Figure 1 as shown in .

[0092] Each base station 105 may communicate with the core network 130, or communicate with each other, or both. For example, the base station 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105), or indirectly (e.g., via the core network 130), or directly and indirectly on the backhaul link 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul link 120 may be or include one or more wireless links.

[0093] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a B node, an evolved B node (eNB), a next generation B node or a gigabit B node (any of which may be referred to as a gNB), a home B node, a home evolved B node, or other suitable terminology.

[0094] 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 term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. 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, 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 communication (MTC) device, etc., which may be implemented in various objects such as electrical appliances or vehicles, meters, etc.

[0095] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 as shown in .

[0096] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on 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 link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates 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 for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0097] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by UE 115. A carrier may operate in a standalone mode in which initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode in which a connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0098] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in an FDD mode), or may be configured to carry both downlink and uplink communications (e.g., in a TDD mode).

[0099] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) of a carrier of a particular radio access technology. Devices (e.g., base stations 105, UEs 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communications on a particular carrier bandwidth, or may be configurable to support communications on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., subband, BWP) or all of a carrier bandwidth.

[0100] The signal waveform transmitted on the carrier may include 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 using MCM techniques, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the 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 received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further improve the data rate or data integrity of communications with UE 115.

[0101] One or more parameter sets for a carrier may be supported, where the parameter set may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter designs. 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 a UE 115 may be limited to the one or more active BWPs.

[0102] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, and the basic time unit can be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the maximum supported subcarrier spacing, and N f The maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources 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).

[0103] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of code element periods (e.g., depending on the length of the cyclic prefix added before each code element period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-time slots containing one or more code elements. Excluding the cyclic prefix, each code element period may contain one or more (e.g., N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or the operating band.

[0104] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication 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 communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0105] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. 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 a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more 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 the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0106] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with a base station 105 (e.g., on a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. 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) on which a logical communication entity operates. The range of such a cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area 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 an external space between or overlapping a geographic coverage area 110, as well as other examples.

[0107] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 (compared to a macro cell), and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A base station 105 may support one or more cells and may also support communications on one or more cells using one or more component carriers.

[0108] 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 to different types of devices.

[0109] In some examples, base stations 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 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, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0110] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and transmissions from different base stations 105 may not be aligned in time in some examples. The techniques described herein may be used for synchronous or asynchronous operation.

[0111] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with 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 that utilizes the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0112] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed with a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving deep sleep mode when not engaged in active communications, operating on a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a subcarrier or resource block (RB) set) within a carrier, within a guard band of a carrier, or outside a carrier.

[0113] The wireless communication system 100 may be configured to support ultra-reliable communication or low latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low latency communication (URLLC) or mission-critical communication. UE 115 may be designed to support ultra-reliable, low latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication 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, critical mission, and ultra-reliable low latency may be used interchangeably herein.

[0114] In some examples, UE 115 may also be able to communicate directly with other UE 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 communication may be within a 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 the base station 105, or may not be able to receive transmissions from the base station 105 for other reasons. In some examples, each group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between each UE 115 without involving the base station 105.

[0115] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these communications. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can use vehicle-to-network (V2N) communications to communicate with roadside infrastructure (such as roadside units), or with the network, or both via one or more network nodes (e.g., base station 105).

[0116] 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 a 5G core (5GC), and the EPC or 5GC may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a base station 105 associated with the core network 130. User IP packets may be delivered via a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0117] Some network devices (such as base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the 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 merged into a single network device (e.g., base station 105).

[0118] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). In general, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features, but these waves may penetrate various structures sufficiently for macro cells to provide service to UEs 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0119] The wireless communication system 100 may also operate in a super high frequency (SHF) zone using a frequency band from 3 GHz to 30 GHz (also known as a centimeter band) or in an extremely high frequency (EHF) zone of a spectrum (e.g., from 30 GHz to 300 GHz) (also known as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antenna of the corresponding device may be smaller and more closely spaced than the UHF antenna. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency zones, and the use of frequency bands specified across these frequency zones may vary by country or regulatory agency.

[0120] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ licensed 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 an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) may employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in a licensed band. Operations in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0121] The base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located in one or more antenna arrays or antenna panels that can 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, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having antenna ports of several rows and columns that the base station 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0122] The base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such technology may be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. 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 for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0123] 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 signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0124] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as the base station 105) or a receiving device (such as the UE 115)) to identify a beam direction used by the base station 105 for later transmission or reception.

[0125] Some signals, such as data signals associated with a particular recipient device, may be transmitted by base station 105 in a single beam direction, e.g., a direction associated with a recipient device, such as UE 115. In some examples, a beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0126] In some examples, transmission 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 the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may transmit a reference signal that may be precoded or uncoded (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)). 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 by base station 105 in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0127] A receiving device (e.g., UE 115) may try multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a base station 105. For example, the receiving device may try multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, 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 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 reception configurations or reception directions. In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). The single reception configuration may be aligned on a beam direction determined based on listening according to different reception configuration directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0128] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate on a logical channel. The media access control (MAC) layer may perform priority handling and multiplex logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission of the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection that supports radio bearers of user plane data between UE 115 and base station 105 or core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0129] UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood that data is correctly received on communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve the throughput of the MAC layer in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0130] A wireless device, such as UE 115, may experience SI in the wireless communication system 100. For example, UE 115 may transmit and receive signals in a full-duplex communication configuration. UE 115 may experience SI because the signal transmitted by UE 115 interferes with the signal reception performed by UE 115. In order to avoid and reduce SI, UE 115 may perform a network-assisted self-measurement technique. UE 115 may receive a measurement configuration from a second wireless device, such as base station 105, to support full-duplex operation using shared resources. UE 115 may use a first antenna array of a first wireless device to transmit a first signal through a shared resource via a first transmission beam. The UE 115 device may monitor the shared resource using a first reception beam via a second antenna array of UE 115 according to the measurement configuration. Then UE 115 may transmit a measurement report to the second wireless device based on the monitoring. Base station 105 may transmit a duplex configuration to UE 115 that configures the full-duplex operation of UE 115 based on the measurement report.

[0131] Figure 2 An example of a wireless communication system 200 that supports network-assisted self-measurement for implementing full-duplex operation according to various aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. The wireless communication system 200 may support full-duplex communication on the same sector. For example, a base station 105-a may include multiple sectors or cells, or multiple sectors or cells may be implemented on two or more base stations. In some examples, different sectors of the base station 105-a may not share the same architecture. Different architectures may include different antenna panels for each sector, different components for each sector, and different baseband processing units for each sector, etc.

[0132] In some cases, base stations 105-a and 105-b may be part of an IAB node. This may include base station 105 connected to central unit 215. UE 115-a may be an example of UE 115, or may also be another wireless device, such as a repeater, a base station, a wireless TRP, or another device capable of transmitting from a first set of antennas and receiving from a second set of antennas. As part of a beamforming communication system, UE 115-a may communicate using transmit and receive beams 210, and base station 105-a may communicate using transmit and receive beams 205.

[0133] UE 115-a may experience SI based on leakage of signals transmitted by beam 210 into a receive port or antenna of UE 115-a. SI may also be caused by reflection of signals transmitted by UE 115-a back to the receive port. This may be an example of a clutter echo. UE 115-a may perform self-measurement for measuring SI. Self-measurement may assist UE 115-a in determining whether UE 115-a has the ability to perform full-duplex communication. For example, if the SI is too high for all beams 210, UE 115-a may determine that it cannot perform full-duplex communication and may employ half-duplex communication.

[0134] The self-measurement may include transmitting a signal from a first antenna set on one or more transmit beams, and measuring a signal received on a second antenna set. The UE 115-a may measure signals received using one or more receive beams 210 (including multiple beam directions). The transmitted signal may leak to a receive antenna port during transmission, or may be reflected back to the antenna port by an object or reflector. The object or reflector may cause a clutter echo. In some cases, the transmit antenna array and the receive antenna array may be the same antenna array, or may be different.

[0135] In some cases, the wireless device may perform self-measurement transparently. In this case, there may be limited signaling or coordination of the self-measurement with other network entities. For example, when the base station 105-a (or data unit (DU)) transmits a downlink signal on one or more beams 205, the base station 105-a may measure the SI at the receiving port of the base station 105-a. The received signal may be measured in the form of a power measurement (such as reference signal received power (RSRP)) to determine the SI. In another example, the UE 115-a (e.g., a mobile terminal (MT)) may transmit an uplink signal on the beam 210. The UE 115-a may measure the signal received at the receiving port of the UE 115-a without coordinating the self-measurement with other network entities (e.g., the base station 105-a).

[0136] In some cases, a wireless device performing self-measurement may not provide a report of the self-measurement results. In some cases, a wireless device may use self-measurement to determine whether the wireless device can support full-duplex communication. A wireless device may also independently determine whether it can perform beam tuning to reduce SI.

[0137] The network may provide a configuration indicating resources for the wireless device to perform self-measurement. The network may configure the device to provide a report on the self-measurement performed by the device. In addition, based on the received self-measurement report, the network may determine the full-duplex capability of the wireless device of the wireless device (e.g., rather than determining the full-duplex capability by the wireless device itself). In some cases, the wireless device may be a scheduled node of the network, which may mean that the wireless device does not have the opportunity or resources to perform self-measurement. In this case, the network may provide a configuration or resources or both so that the wireless device (e.g., UE115-a) can perform self-measurement. In some cases, UE 115-a may not have the ability to perform self-measurement or autonomously determine the configuration. In this case, the network may alternatively provide a configuration and signaling that enables UE 115-a or base station 105-a to perform self-measurement.

[0138] Additionally, network-assisted self-measurement may provide the network with more control and flexibility to determine the operation mode and scheduling of wireless devices served by the network.

[0139] UE 115-a (e.g., MT) may be configured with a measurement configuration that indicates that one or more uplink signals (e.g., sounding reference signals (SRS)) are transmitted via one or more beams 210. This configured uplink signal may be used for self-measurement. In some cases, the network may configure UE 115-a in the measurement configuration to have a periodic SRS resource set for continuous self-measurement by UE 115-a. Utilization of the configured SRS resource set by UE 115-a may be identified as self-measurement. The same SRS transmission may also be used for measurements performed by another node (such as base station 105-a (e.g., parent node)) or cross-link interference (CLI) measurements performed by other UEs 115 (e.g., other MTs). The selection of which beam 210 to use for SRS transmission may be indicated by the network to UE 115-a. For example, the network may indicate beam 210 in a spatial relationship parameter (e.g., spatialRelationInfo (spatial relationship information)). In some examples, UE 115-a may select beam 210 for transmission for SI measurement. For example, UE 115-a may determine to select beam 210 for transmission based on not receiving an indication or parameter indicating the beam from the network.

[0140] In one example, the beam 210 direction can be selected based on potential active or candidate beams 210 for uplink communication by UE 115-a to a parent node (e.g., base station 105-a). The active or candidate beams 210 can correspond to active links or links scheduled to become active during a time period. In another example, the direction of the beam 210 can be selected based on the location of a detected reflector and in order to train the beam 210 (e.g., both transmit and receive beams) toward or away from the detected reflector.

[0141] In addition, the transmission power can be determined autonomously by UE 115-a or based on a configuration received from the network. The transmission power of the signal used for SI measurement can be dynamically selected or configured so that the transmission power of the signal used for SI measurement can be different from the transmission power of other transmissions of UE 115-a or another wireless device (for example, different from other signals sent on the uplink). For example, compared with the power of other signaling, a larger power (for example, up to the maximum available transmission power of UE 115-a) can be used by UE 115-a for SI measurement transmission. This larger power can enable UE 115-a to determine more accurate measurements of SI (such as those caused by clutter echoes from reflectors or other objects). A smaller power can also be selected for the signal used for SI measurement. This smaller power can be used to implement local SI measurements while reducing interference to other active links. Therefore, SI measurements can be performed with lower power so as not to interfere with other communications occurring at UE 115-a.

[0142] In some cases, UE 115-a may request the network to provide resources or configuration for SI measurement. UE 115-a may transmit the request to the network using beam 210. The request may include an indication of the beam 210 or resources, or both, that are available for SI measurement at UE 115-a. Figure 3 Methods for SI measurements are described.

[0143] In response, the base station 105-a (e.g., or other network entity) may indicate a self-measurement gap (e.g., a time period in which self-measurements are performed) as part of a measurement configuration indicated to the UE 115-a. The self-measurement gap indicated by the base station 105-a may be a future set of resources described in the measurement configuration for the UE 115-a to use to perform SI measurements. The measurement configuration may indicate future time and / or frequency resources for the self-measurement gap. For example, the measurement configuration may indicate when a measurement gap may occur, on which one or more frequency resources the gap occurs, on which one or more time slots the gap occurs, one or more beam directions for SI measurements, one or more antennas for SI measurements, other resource parameters, and any combination thereof.

[0144] During the configured self-measurement gap indicated in the measurement configuration from the base station 105-a, the UE 115-a may not be scheduled by the base station 105-a to receive any other downlink signaling on the resources of the self-measurement gap. Therefore, the UE 115-a can perform self-measurement during the configured self-measurement gap without interfering with or losing other transmissions. In the request transmitted by the UE 115-a, in some cases, the UE 115-a may specifically indicate a request for a measurement gap. The self-measurement gap (e.g., measurement window) may be configured as periodic, semi-persistent, or dynamic (e.g., resources indicated in downlink control information (DCI)). The UE 115-a may also receive a configuration to receive and measure a set of one or more downlink signals (e.g., reference signals, synchronization signals, data transmissions, control transmissions, etc.) from the base station 105-a (e.g., parent node) or measure a set of SRSs from at least one other UE 115. In some cases, the configuration for measuring these other signals may apply to the same resources as the measurement gap. For example, FDM or CDM techniques, or both, may be used to orthogonalize other signals relative to the signal being measured.

[0145] In addition, the base station 105-a can also provide a self-measurement configuration to the UE 115-a. For example, the self-measurement configuration may include which resources are to be used for self-measurement (e.g., at least partially aligned with scheduled uplink transmissions), which receive beams are to be used for self-measurement, and the like. The network may also configure the UE 115-a with a self-measurement report configuration. The report may be periodic, semi-static, dynamic, or event-triggered. The UE 115-a may report which transmit and receive beam pairs may and may not be used for full-duplex communication based on SI measurements. The UE 115-a may also report associated SI measurements in the measurement report, and the base station 105-a may select which transmit and receive beam pairs may and may not be used for full-duplex communication. The SI measurement values ​​may include one or more of a received signal strength indicator (RSSI), a reference signal received power (RSRP), a signal to interference noise ratio (SINR), a channel quality indicator (CQI), a measured delay of one or more clutter echoes, or other signal measurements.

[0146] The base station 105-a can communicate with the UE 115-a based on the measurement configuration (including the self-measurement configuration). The base station 105-a can configure the transmission of the downlink signal (e.g., PDCCH transmission, PDSCH transmission) based on the configuration. For example, the base station 105-a can determine one or more SI values ​​(including one or more of RSSI, RSRP, SINR, and CQI) according to the measurement configuration, and can set one or more transmission parameters based on the one or more SI values. For example, based on the one or more SI values ​​determined using the measurement configuration, the base station 105-a can use the SI value to set one or more transmission parameters, including transmission power level, decoding rate, multiplexing scheme, MCS value, etc., or any combination thereof. Based on the monitoring performed by the UE 115-a according to the measurement configuration, the UE 115-a can similarly communicate with the base station 105-a. For example, the UE 115-a can determine one or more SI measurement values ​​according to the measurement configuration, including one or more of RSSI, RSRP, SINR, and CQI. UE 115-a may configure the transmission of one or more uplink signals (e.g., PUCCH transmission, PUSCH transmission) to base station 105-a based on the measurement. For example, UE 115-a may determine one or more SI values ​​(including one or more of RSSI, RSRP, SINR, and CQI) based on the measurement configuration, and may set one or more transmission parameters based on the one or more SI values. For example, based on one or more SI values ​​determined using the measurement configuration, UE 115-a may use the SI values ​​to set one or more transmission parameters, including a transmission power level, a coding rate, a multiplexing scheme, an MCS value, etc., or any combination thereof.

[0147] In some cases, UE 115-a may report the results of SI measurements using a CLI measurement procedure (which may include a CLI report). The CLI report may indicate an SRS-RSRP measurement, or a CLI-RSSI measurement, or both. The SRS-RSRP resource, or the CLI-RSSI resource, or both may be used to indicate an SI measurement. Any of these measurements may be an indication of an SI measurement.

[0148] In other cases, UE 115-a may report CQI as an SI measurement. UE 115-a may report CQI by configuring CSI-IM or zero-power or non-zero-power CSI-RS resources on the same resource set. These resources may be configured as resources for transmitting indications of SI measurements.

[0149] UE 115-a can reduce SI and SI caused by spurious echoes by utilizing spatial isolation. Spatial isolation can include selecting transmit and receive beams 210 so that SI can be avoided or reduced. UE 115-a can also use beam nulling to reduce SI. UE 115-a can also perform SI cancellation internally in the analog and digital domains.

[0150] The base station 105 may similarly experience SI due to the transmitted signal leaking the spurious echo. The base station 105 may also reduce SI by performing spatial isolation, beam nulling, and SI cancellation using the methods described herein with respect to the UE 115 or wireless device. The base station 105 may also select which beams 205 to use based on the SI measurements.

[0151] The network operation measurement configuration as described herein may be applicable to base stations 105 and UEs 115, but may also be applicable to communications between the central unit 215 and base stations 105-a and 105-b.

[0152] Figure 3 An example of an antenna diagram 300 supporting network-assisted self-measurement for implementing full-duplex operation according to aspects of the present disclosure is illustrated. In some examples, the antenna diagram 300 can implement aspects of the wireless communication systems 100 and 200. The node 305 can be a component of a wireless device that performs SI measurements. For example, the node 305 can be a component of a UE 115, a base station 105, or an IAB node (e.g., an IAB parent node or an IAB child node), as described in reference to Figure 1 and Figure 2 Node 305 may include antenna arrays 310 and 315. Antenna array 310 may be an example of a transmit antenna array. Antenna array 315 may be an example of a receive antenna array. A wireless device corresponding to node 305 may use transmit antenna array 310 and corresponding transmit beam 320 to transmit signal 335. In this example, antenna diagram 300 illustrates a transmit beam 320 with a main lobe and a corresponding side lobe 360 ​​of transmit beam 320. The size of the lobe of the depicted transmit beam 320 may represent the amount of transmit gain in a particular direction during the transmission of signal 335. Signal 335 may be a reference signal transmitted for the purpose of SI measurement by the node, or may be other signals, such as signals for communicating with node 345. Node 345 may be an example of another wireless device, such as UE 115, base station 105, IAB node (e.g., IAB parent node or IAB child node) or central unit. SI at node 305 may be caused by reflectors 330 or other SI.

[0153] Based on the measurement configuration, the node 305 can select a beam 320 and a signal 335 to transmit in order to measure SI caused by reflectors 330, clutter echoes, and other leakage interference. The transmit array 310 can transmit a signal 335, which can be received at the receive array 315 as a reflected signal 340. The receive beam 325 can receive other signals 350 from other wireless devices (e.g., node 345-a). In this example, the antenna diagram 300 illustrates a receive beam 325 and a corresponding lobe 360. The transmit beam 320 can be as shown in FIG. Figure 2 The receive beam 325 may be an example of a beam 210 as described above. Figure 2 An example of beam 210 is described.

[0154] To measure SI, the node 305 may transmit one or more signals 335 from the transmit antenna array 310 using one or more transmit beams 320. The node 305 may then measure the signals received on the second antenna array 315 using one or more receive beams 325. The one or more transmit beams 320 may transmit any type of signal 335. The transmit beam 320 may also transmit a reference signal as the signal 335, such as a reference signal specific to SI measurement, or another reference signal for other uplink or downlink transmissions of the node. The signal 335 transmitted for SI measurement may also be part of other communications of which the node 305 is a part. For example, the node 305 may be in communication with one or more other nodes 345. The node 305 may therefore use the signal 335 transmitted to another node as the signal 335 for SI measurement. The transmission to the other node may be associated with some cell-specific signals that may be broadcast over the air, and may therefore not be intended for a specific receiver. For example, the signal 335 transmitted for SI measurement may be a synchronization signal block (SSB) type signal.

[0155] In another scenario, the signal 335 transmitted for SI measurement may be a signal sent for the purpose of generating SI measurements made by the node 305. In this scenario, there may be flexibility in selecting a transmission configuration for SI measurement. For example, the parameters of the transmission configuration of the signal 335 transmission may include power, beam direction, and other parameters. These parameters may be selected to transmit the signal 335 for SI measurement. The flexibility in selecting these parameters may increase the amount of resources used for SI transmission.

[0156] One or more beams 320 may transmit signal 335 for SI measurement. For example, beam 320 may transmit signal 335-c, which may be reflected from reflector 330 as signal 340. Reflector 330 may be an example of a cause of a nuisance echo.

[0157] Then, the receive antenna array 315 and the receive beam 325 can measure SI by measuring a received power measurement (such as total received power) of the received signal 340. The received power measurement can be used to determine that SI occurs based on the transmitted signal 335 (e.g., signal 335-c). In an example, the received power measurement can be a measurement of the received signal strength (e.g., a received signal strength indicator (RSSI)). In order to measure the received power, the receive antenna array 315 may not need to know what type of signal the transmit antenna array 310 transmits. In order to determine the total power, the receive antenna array 315 can know on what resource the signal 335-c is transmitted. This measurement configuration can be applicable to situations where the transmit antenna array 310 can use any type of signal.

[0158] The receive antenna array 315 may also measure SI as a measurement of the reference signal received power (RSRP) of the received signal 340. To measure RSRP, the receive antenna array 315 may measure the received power of the received signal 340 and may know what type of signal 335-c is transmitted. This measurement configuration may be applicable to situations where the transmit antenna array 310 transmits a reference signal (e.g., a common reference signal or a reference signal specific to SI measurement). Other types of SI measurements include signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), channel quality indicator (CQI) measurements, measured delay values ​​of clutter echoes, and the like.

[0159] In some cases, the transmit beam 320 selected for signal transmission may be fixed. For example, the transmit beam 320 may be transmitted in a specific direction with known properties (e.g., power level, beam width, etc.). A first transmit beam 320 may be selected and used to transmit signal 335-a. Signal 335-c may be reflected by reflector 330 as reflected signal 340. In these cases, multiple receive beams 325 may be used to measure received signal 340. For example, UE 115 may sweep one or more receive beams 325 in a set of different directions in one or more time periods to measure reflected signal 340.

[0160] In another case, a first transmit beam 320 may be selected, and each receive beam 325 may be selected at a time to receive and measure a power measurement to determine the SI of the reflected signal. The transmit beam 320 may then be changed to another transmit beam pointing in another direction or having different parameters (not shown), and another signal may be transmitted and may be swept through each receive beam 325 again. The receive array 315 may sweep through each receive beam 325 to receive and measure the reflected signal 340. The transmit beam 320 may be continuously changed until each transmit beam has transmitted a signal 335, which has also been received by each receive beam 325. Thus, a measurement of SI may be determined for each transmit beam 320 and each receive beam 325 combination.

[0161] The node 305 may generate a measurement report including one or more SI measurements for one or more beams or beam pairs, and the network (e.g., a base station) may use the measurement report to configure the node 305 to a duplex configuration to configure which one or more beams or beam pairs the node 305 is to use, and to control whether the node 305 is scheduled to operate in full-duplex mode for resources. The duplex configuration may also configure the node 305 to use beam nulling to reduce or avoid SI. In beam nulling, the receive array 315 may align the main lobe (e.g., with the highest receive gain) of the receive beam 325 in the direction of the node 345-a so as to receive the signal 350 from the node 345-a. The main lobe of the beam 325 may be selected so that it has the highest receive gain. The receive array 315 may also place the null 355-a in the direction of the clutter echo from the reflector 330. The null 355-a placement may reduce the clutter echo 340 caused by the reflection of the signal 335 transmitted by the transmit array 310.

[0162] The sectored transmitter beam 320 may also place a null 355-b in the direction of the clutter reflector 330 to reduce the amount of transmit gain of the signal 335-b transmitted in the direction of the reflector 330. The null 355 may be a point between lobes 360. The null placement may be selected based on the organization of the clutter, and the number of clutter reflectors 330 or the number of clutter echoes.

[0163] Figure 4 An example of a process flow 400 supporting network-assisted self-measurement for implementing full-duplex operation in accordance with aspects of the present disclosure is illustrated. In some examples, the process flow 400 may implement aspects of the wireless communication system 100. The process flow 400 may include a UE 115-b, which may be as described with reference to Figure 1 and 21. The UE 115-a described above is an example of a UE 115-b. The UE 115-b may be an example of an IAB child node, an MT, an IAB parent node, or another wireless device. The process flow 400 may also include a base station 105-c, which may be as described with reference to Figure 1 and 2 An example of a base station 105 is described. Base station 105-c may be an example of an IAB parent node or central unit.

[0164] At 405, UE 115-b may transmit a configuration request to base station 105-c. The measurement configuration received at 410 may be based on the configuration request. The configuration request may indicate a resource request, a number of beams, or both.

[0165] At 410, UE 115-b may receive a measurement configuration for supporting full-duplex operation using shared resources. The measurement configuration may configure UE 115-b to perform the operations described herein. For example, the measurement configuration may indicate a periodic resource set, which may indicate a shared resource as a periodic shared resource in which UE 115-b will perform SI measurements. The measurement configuration may also indicate a self-measurement gap, wherein UE 115-b may be scheduled to monitor a signal within the self-measurement gap to perform SI measurements. The measurement gap may be a periodic self-measurement gap, a semi-static self-measurement gap, a dynamic self-measurement gap, an event-triggered self-measurement gap, or any combination of these gaps. The measurement configuration may also indicate an FDM configuration, a code division multiplexing (CDM) configuration, or both for shared resources. The measurement configuration may also configure UE 115-b with which one or more antenna arrays to use to transmit signals via one or more transmit beams, and which one or more antenna arrays to use to measure SI using one or more receive beams. For example, the measurement configuration may indicate transmitting signals in shared resources via a first transmit beam using a first antenna array, and measuring SI in shared resources via a first set of one or more receive beams using a second antenna array (eg, sweeping across a set of receive beams).

[0166] At 415, UE 115-b may transmit a first signal via a first transmission beam using a first antenna array of UE 115-a over a shared resource. The first signal may be a reference signal, a synchronization signal, a control transmission, a data transmission, or a combination of these transmissions. UE 115-b may transmit the first signal using a transmission power that may be indicated in the measurement configuration. UE 115-b may also transmit the first signal using a first transmission beam having a beam direction indicated in the measurement configuration. UE 115-b may transmit the first signal using a first transmission beam having a beam direction pointing in the direction of a reflective object.

[0167] At 420, UE 115-b may monitor the shared resource using a first receive beam via a second antenna array of the first device according to the measurement configuration. UE 115-b may monitor the shared resource using a set of receive beams via a second antenna array according to the measurement configuration. The set of receive beams may correspond to active links or links scheduled to be active during a defined time period.

[0168] At 425, UE 115-b may communicate with base station 105-c (e.g., a second wireless device). For example, the communication may include transmitting a measurement report to base station 105-b based on the monitoring at 430. In other cases, UE 115-b may communicate at 425 by using observed SI measurement values ​​(e.g., RSRP values) to select one or more of MCS, coding rate, transmission power, or any combination thereof for uplink communication with base station 105-c. In the case where UE 115-b transmits a measurement report at 430, the measurement report may indicate downlink reference signal measurements, reference signal measurements, or both based on an FDM configuration, a CDM configuration, or both for a shared resource. The measurement report may be a periodic measurement report, a semi-static measurement report, a dynamically generated measurement report, an event-triggered measurement report, or a combination of these reports. The measurement report may also indicate at least one measurement value, such as an RSRP value, an RSSI value, an SINR value, a CQI value, a clutter echo delay value, or a combination of these values. The measurement report may also indicate a cross-link interference measurement or a reference signal measurement, or both. UE 115-b may also generate and include in the measurement report a cross-link interference measurement for a shared resource based on the monitoring. UE 115-b may also generate and include in the measurement report a reference signal measurement for a shared resource based on the monitoring. In some examples, the reference signal measurement may be a CSI-RS measurement.

[0169] UE 115-b may also receive control signaling from base station 105-c to allocate resources for uplink transmission, downlink transmission, or both based on the measurement report. UE 115-b may communicate uplink transmission, downlink transmission, or both within the resource based on the control signaling. In the case where base station 105-c is a central unit and UE 115-c is an IAB node, UE 115-b may receive control signaling that allocates resources for scheduling by the IAB node based on the measurement report. UE 115-b as an IAB node may schedule uplink transmission, downlink transmission, or both within the resource.

[0170] In some cases, at 435, UE 115-b may receive a duplex configuration that configures full-duplex operation of UE 115-b based on the measurement report. Base station 105-c may transmit the duplex configuration based on the communication at 425 (including based on receiving the measurement report at 430). UE 115-b may communicate through shared resources via a first antenna array and a second antenna array based on the duplex configuration. The duplex configuration may indicate at least one condition, at least one configuration, or both that UE 115-b may support full-duplex operation. The at least one condition may be one or more of a power level, a beam direction, a time period, or any combination thereof that the base station 105-c determines that UE 115-b will support full-duplex operation. The duplex configuration may also indicate at least one transmit-receive beam pair that UE 115-b will support full-duplex operation. The duplex configuration may also indicate at least one condition, at least one configuration, or both that UE 115-b may use the at least one transmit-receive beam pair to support full-duplex operation. The duplex configuration may also indicate at least one transmit-receive beam pair that UE 115-b will not support full-duplex operation. The base station 105-c may then schedule UE 115-b based on the duplex configuration. In some cases, the duplex configuration may include scheduling information (e.g., a grant), or the base station 105-c may communicate a separate control signal to schedule UE 115-b. For example, the base station 105-c may transmit (e.g., in a DCI) a grant to schedule shared resources for UE 115-b to simultaneously transmit and receive in the shared resources using a specific transmit-receive beam pair that the base station 105-c has determined that UE 115-b supports full-duplex operation. In another example, when the base station 105-c determines that UE 115-b does not perform full-duplex operation, the base station 105-c may transmit (e.g., in a DCI) a grant to schedule shared resources for UE 115-b to transmit or receive but not both in the shared resources using a specific transmit or receive beam.

[0171] Figure 5 A block diagram 500 of a device 505 supporting network-assisted self-measurement for implementing full-duplex operation according to aspects of the present disclosure is shown. The device 505 may be an example of aspects of a UE 115 as described herein. The device 505 may include a receiver 510, a communication manager 515, and a transmitter 520. The device 505 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0172] The receiver 510 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to network-assisted self-measurement for implementing full-duplex operation, etc.). The information may be passed to other components of the device 505. The receiver 510 may be a reference Figure 8 Examples of aspects of the described transceiver 820. The receiver 510 may utilize a single antenna or a collection of antennas.

[0173] The communication manager 515 may receive a measurement configuration for using a shared resource to support full-duplex operation; transmit a first signal through the shared resource via a first transmit beam using a first antenna array of a first wireless device; monitor the shared resource using a first receive beam via a second antenna array of the first wireless device according to the measurement configuration; and transmit a measurement report to a second wireless device based on the monitoring. The communication manager 515 may be an example of aspects of the communication manager 810 described herein.

[0174] In some cases, the communication manager 515 may receive a measurement configuration for using a shared resource to support full-duplex operation; transmit a first signal through the shared resource via a first transmit beam using a first antenna array of a first wireless device; monitor the shared resource using a first receive beam via a second antenna array of the first wireless device according to the measurement configuration; and communicate with a second wireless device based on the monitoring. The communication manager 515 may be an example of aspects of the communication manager 810 described herein.

[0175] The communication manager 515 or its subcomponents may be implemented in hardware, in code (e.g., software or firmware) executed by a processor, or any combination thereof. If implemented in code executed by a processor, the functions of the communication manager 515 or its subcomponents may be performed by a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device designed to perform the functions described in the present disclosure, discrete gate or transistor logic, discrete hardware components, or any combination thereof.
