Technical Field

[0003] The following is a measurement report concerning wireless communication, including full-duplex multibeam communication. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. 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), LTE-A Advanced (LTE-A), 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 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 of which simultaneously supports communication with multiple communication devices, which may also be referred to as User Equipment (UE).

[0005] In some wireless communication systems, communication devices (e.g., base stations, UEs) can support full-duplex communication. In some cases, full-duplex communication may increase the interference and self-interference experienced by the communication devices. Summary of the Invention

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses for measurement reporting supporting full-duplex multi-beam communication. Typically, the described techniques provide for the capture and utilization of base station interference and UE self-interference metrics for beam and / or link management / optimization. The UE can identify base station interference and UE self-interference information and transmit it to the base station. Typically, base station interference (e.g., a first set of signal strength metrics) can include UE measurement performance metrics (e.g., Reference Signal Received Power (RSRP), Reference Signal Strength Indicator (RSSI), Signal-to-Noise Ratio (SNR), Channel Quality Information (CQI), throughput rate, etc.) of the base station's transmitted beams (e.g., each available transmitted beam or subset thereof of the base station on a per-UE received beam basis) when received using different receive beams of the UE. UE self-interference (e.g., a second set of signal strength metrics) can include UE measurement performance metrics (e.g., RSRP, RSSI, SNR, CQI, throughput rate, etc.) of the UE's transmitted beams (e.g., each available transmitted beam or subset thereof of the UE on a per-UE received beam basis) when received using different receive beams of the UE. The UE can send the actual RSRP value (or RSSI, SNR, CQI, etc.), a flag indicating whether the measured transmit / receive beam pair meets the threshold, etc.

[0007] The base station can use this information (as well as similar information from other UEs) for link management / optimization, beam management / optimization, etc., of the UE and / or other UEs. For example, the base station can schedule or otherwise configure a UE to receive downlink signaling via a pair or more pairs of base station transmit beams exhibiting high signal strength (e.g., high RSRP value) and UE receive beams, and the base station can typically choose to schedule or otherwise configure a UE to simultaneously transmit uplink signaling via one or more UE transmit beams exhibiting low signal strength (e.g., low RSRP value) in combination with one or more receive beams of the UE configured for downlink reception. Therefore, the combination of the two tables (e.g., first and second signal strength metric sets) will provide an indication not only of how strong the received beams of different base stations are when using different UE receive beams but also of how much self-interference different UE transmit beams cause to different UE receive beams, and thus the base station's reception and use of this information can improve management / optimization decisions (e.g., scheduling and other configuration decisions). The UE can then communicate with the base station using the transmit / receive beam pairs selected based on this information.

[0044] Some wireless communication systems can utilize full-duplex wireless communication, where devices (e.g., UEs and / or base stations) are capable of simultaneously transmitting and receiving. This full-duplex communication can be enhanced using beamforming techniques (e.g., directional transmission and / or reception), where transmit / receive beam pairs are used for directional transmission. In the millimeter-wave (mmW) and Asia-Pacific Hertz (THz) frequency ranges, the number of antenna panels (e.g., panels consisting of antennas, antenna ports, antenna configurations, beamforming configurations, etc.) can be utilized to increase full-duplex communication, supporting more efficient beamforming spatial separation and thus enhancing full-duplex communication. Such wireless communication systems can use interference introduced from the base station performing the transmission to select beam pairs for communication with different UEs. However, this base station interference may not provide a comprehensive picture of all interference experienced by the UE (e.g., due to UE transmissions). This can limit the effectiveness of beam management / optimization techniques.

[0045] The aspects of this disclosure are initially described in the context of wireless communication systems. Generally, the described techniques provide for the capture and utilization of both base station interference and UE self-interference metrics for beam and / or link management / optimization. The UE can identify base station interference and UE self-interference information and transmit it to the base station. Typically, base station interference (e.g., a first set of signal strength metrics) can include UE measurement performance metrics (e.g., RSRP, RSSI, SNR, CQI, throughput rate, etc.) for the UE's received beam and the base station's transmitted beam (e.g., each available transmitted beam or subset thereof of the base station on a per-receive-beam basis for the UE). UE self-interference (e.g., a second set of signal strength metrics) can include UE measurement performance metrics (e.g., RSRP, RSSI, SNR, CQI, throughput rate, etc.) for the UE's received beam and the UE's transmitted beam (e.g., each available transmitted beam or subset thereof of the UE on a per-receive-beam basis for the UE). The UE can transmit actual RSRP values ​​(or RSSI, SNR, CQI, etc.), flags indicating whether the measured transmit / receive beam pair meets a threshold, etc.

[0046] The base station can use this information (and similar information from other UEs) for link management / optimization, beam management / optimization, etc., of the UE and / or other UEs. For example, the base station can schedule or otherwise configure UEs to receive downlink signaling via a base station transmit beam and UE receive beam that exhibit high signal strength (e.g., high RSRP value) in one or more combinations, and the base station can typically choose to schedule or otherwise configure UEs to simultaneously transmit uplink signaling via one or more UE transmit beams that exhibit low signal strength (e.g., low RSRP value) in combination with one or more receive beams of UEs configured for downlink reception. If a particular UE transmit beam and a particular UE receive beam combination exhibit high signal strength, this may correspond to high self-interference between those beams, and therefore, uplink transmissions by the UE using the particular UE transmit beam may be undesirable if the particular UE receive beam is also used for downlink reception, whereas different UE transmit beams can be used for uplink signaling with relatively low self-interference as indicated by such beam combinations exhibiting low signal strength. Therefore, the combination of the two tables (e.g., first and second signal strength metric sets) will provide not only an indication of how strong the received beams of different base stations are when different UEs receive beams, but also an indication of how much self-interference different UE transmit beams cause to different UE receive beams. Thus, the base station's reception and use of this information can improve management / optimization decisions (e.g., scheduling and other configuration decisions). When making scheduling or other management decisions regarding the beams that any UE will use for downlink or uplink communication, the base station can consider this information received from multiple UEs (e.g., what base station transmit beams are used for communication with one UE might affect what base station transmit beams are used for communication with another UE, and this might have further spillover effects on what UE receive and UE transmit beams are used by any particular UE). The UE can then use the transmit / receive beam pair selected based on this information to communicate with the base station.

[0047] Aspects of this disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts related to measurement reports of full-duplex multi-beam communication.

[0048] Figure 1Examples of a wireless communication system 100 supporting full-duplex multi-beam communication measurement reports according to various aspects of this disclosure are 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 an LTE network, an LTE-A network, an LTE-A Pro network, or an NR network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0049] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be different types of devices or devices with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, on which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographical area over which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0050] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be different types of devices or devices with different capabilities. Figure 1 Examples of UE115s are illustrated herein. The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115s, base stations 105, or network equipment (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment). Figure 1 As shown.

[0051] Base station 105 can communicate with core network 130, communicate with each other, or both. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) or both via backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 can be one or more radio links or include one or more radio links.

[0052] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station, radio base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB or gigabit NodeB (any of which may be referred to as gNB), home NodeB, home eNodeB or other suitable terms.

[0053] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in a variety of objects, such as appliances or vehicles, meters, etc.

[0054] like Figure 1 As shown, the UE 115 described herein can communicate with various types of devices, such as other UE 115s that may sometimes act as relays, as well as base station 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0055] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the radio spectrum (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels of 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 coordinating operations for the carrier, user data, or other signaling. Wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with UE 115. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0056] In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. The carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Channel Number (EARFCN)) and can be located according to a channel grid for discovery by UE115. The carrier can operate in standalone mode, in which initial acquisition and connection can be performed by UE115 via the carrier, or in non-standalone mode, in which different carriers (e.g., those with the same or different radio access technologies) are used to anchor the connection.

[0057] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0058] A carrier can be associated with a specific bandwidth of the radio spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of several defined bandwidths of a carrier used for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105 or UE 115, or both) can have a hardware configuration that supports communication on a specific carrier bandwidth, or can be configured to support communication 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 communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate on a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0059] The signal waveform transmitted via a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or DFT-S-OFDM). In a system employing MCM, a resource element can consist of one symbol period (e.g., the duration of a modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely proportional. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate UE 115 may achieve. Wireless communication resources can refer to a combination of radio spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and using multiple spatial layers can further increase the data rate or data integrity for communication with UE 115.

[0060] One or more parameter sets (numerologies) of a carrier can be supported, where the parameter set may include subcarrier spacing (Δf) and cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter sets. In some examples, the UE 115 can be configured with multiple BWPs. In some examples, a single BWP of a carrier can be active at a given time, and the communication of the UE 115 can be restricted to one or more active BWPs.

[0061] The time interval of base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resource can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0062] Each frame may include multiple 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 (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple 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 multiple symbol periods (e.g., depending on the length of the cyclic prefix preceding each symbol period). In some wireless communication systems 100, time slots may be further 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) symbols. f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0063] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of short TTIs (sTTIs)).

[0064] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region (e.g., a control resource set (CORESET)) of the physical control channel can be defined by a number of symbol periods and can extend across the system bandwidth of the carrier or a subset thereof. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of the control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format having a given payload size. The search space set can include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.

[0065] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used (e.g., via a carrier) to communicate with base station 105 and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of base station 105, the extent of such cells can range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or include buildings, subsets of buildings, external spaces between or overlapping geographic coverage areas 110, etc.

[0066] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access for UE 115 with a service subscription to a network provider supporting the macro cell. In contrast, small cells can be associated with a low-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with a small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), UE 115 associated with a user in a home or office, etc.). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.

[0067] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access to different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0068] In some examples, base station 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 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. Wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0069] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0070] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices integrated with sensors or meters to measure or capture information and relay that information to a central server or application, which uses the information or presents it to a person interacting with the application. Some UE 115 devices can be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

[0071] Some UE 115s can be configured to operate in a power-saving mode, 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 can be performed at a reduced peak rate. Other power-saving techniques for UE 115s include entering a power-efficient deep sleep mode when not engaged in active communication, operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a carrier's guard band, or outside the carrier.

[0072] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or a combination thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services such as mission-critical key-touch (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritizing services, and mission-critical services can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0073] In some examples, UE 115 can also communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, the group of UE 115s communicating via D2D communication can 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, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without the involvement of base station 105.

[0074] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information about service conditions, signaling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or communicate with both.

[0075] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), user plane function (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to network operator IP service 150. Network operator IP service 150 can include access to the Internet, one or more intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0076] Some network devices (such as base station 105) may include sub-components (such as access network entity 140), which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145, which may be referred to as a radio head, smart radio head, or transmit / receive point (TRP). 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 combined into a single network device (e.g., base station 105).

[0077] Wireless communication system 100 can operate using one or more frequency bands typically in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is generally referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range is approximately 1 decimeter to 1 meter. UHF waves may be blocked or redirected by buildings and environmental features, but these waves can penetrate structures sufficiently to enable macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0078] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region (also known as the centimeter band) using a frequency band from 3 GHz to 30 GHz, or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter wave band). In some examples, the wireless communication system 100 can support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices can be smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. Transmissions using one or more different frequency regions can employ the techniques disclosed herein, and the designated use of frequency bands across these frequency regions may vary by country or regulatory authority.

[0079] Wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 can employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be based on a combination of carrier aggregation configuration and component carriers operating in licensed bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0080] Base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be juxtaposed at an antenna accessory (such as an antenna tower). In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, 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 beamforming for signals transmitted via the antenna ports.

[0081] 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. This technique can be referred to as spatial multiplexing. Multiple signals can be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include 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.

[0082] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element can be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0083] Base station 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to implement beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device such as base station 105, or by a receiving device such as UE 115) to identify the beam direction for later transmission or reception by base station 105.

[0084] Base station 105 may transmit signals, such as data signals associated with a specific receiving device, in a single beam direction (e.g., the direction associated with a receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the 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 UE 115 may report to base station 105 an indication of the signal it received that has the highest signal quality or other acceptable signal quality.

[0085] In some examples, transmissions performed by devices (e.g., base station 105 or UE 115) may be performed using multiple beam directions, and the devices may use a combination of digital pre-decoding or radio beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating pre-decoding weights for one or more beam directions, and this feedback may correspond to the number of beam configurations across the system bandwidth or one or more sub-bands. Base station 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information (CSI) reference signals (CSI-RS)), which may be pre-decoded or undecoded. UE 115 may provide feedback for beam selection, which may be a pre-decoded matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, 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 employ similar techniques to transmit signals multiple times in different directions (e.g., to identify the beam direction subsequently transmitted or received by UE 115), or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0086] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by: receiving via different antenna subarrays; processing the received signals according to different antenna subarrays; receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights); or processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array. Any of these methods can be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). The single receiving configuration can be aligned on a beam direction determined based on listening according to different receiving configuration directions (e.g., a beam direction determined based on listening to multiple beam directions to have the highest signal strength, highest SNR, or other acceptable signal quality). As described herein, in some cases, the receiving device can transmit simultaneously via one or more beams and receive simultaneously via one or more other beams.

[0087] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of the RRC connection (which supports radio bearers for user plane data) between UE 115 and base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0088] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception over communication link 125. HARQ can 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 can improve the throughput of the MAC layer under adverse radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device can support simultaneous time-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in the previous symbol within that time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0089] UE 115 can use different receive beams of UE 115 to identify a first set of signal strength metrics for different transmit beams of base station 105. UE 115 can also use different receive beams of UE 115 to identify a second set of signal strength metrics for different transmit beams of UE 115. UE 115 can send an indication of the first and second signal strength metrics to base station 105. UE 115 can then communicate with base station 105 based on this indication.

[0090] Base station 105 can receive from UE 115 an indication of a first signal strength metric set of the signal strength of the transmit beam of base station 105 using the receive beam of UE 115, and a second signal strength metric set of the signal strength of the transmit beam of UE 115 using the receive beam of UE 115. Based on this indication, base station 105 can select one or more transmit beams of base station 105 for downlink communication with UE 115, and one or more transmit beams of UE 115 for uplink communication. Base station 105 can then communicate with UE 115 based on this selection.

[0091] Figure 2 Examples of a wireless communication system 200 supporting full-duplex multi-beam communication measurement reports according to various aspects of this disclosure are illustrated. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. The wireless communication system 200 may include a UE 205, a base station 215, a base station 220, and a base station 225 comprising a set of panels 210 (four panels 210 are shown by way of example only), which may be examples of the corresponding devices described herein. Object 230 may be located near one or more devices of the wireless communication system 200, and the wireless communication system 200 may include buildings or any other structures that interfere with, modify, reflect, or otherwise affect wireless communication between devices.

[0092] In some aspects, UE 205 can support full-duplex communication, enabling UE 205 to transmit wireless communications using one or more transmit beams and receive wireless communications using one or more receive beams. Similarly, base stations 215, 220, and / or 225 can also support beamforming communication to UE 205 using different transmit beams, different receive beams, etc. (e.g., full-duplex communication can also be supported). For example, base stations 215, 220, and / or 225 can use the respective base station's transmit beam to perform downlink transmissions to UE 205, and UE 205 can use the corresponding receive beam of UE 205 to receive such downlink transmissions. Conversely, UE 205 can use its transmit beam to perform uplink transmissions to one or more of base stations 215, 220, and / or 225, which are received using the corresponding receive beam of the base station.

[0093] For full-duplex communication, UE 205 can perform uplink transmission using its transmit beam and receive downlink transmission from any of base stations 215, 220, and / or 225 using its receive beam. In some aspects, UE 205 can utilize one or more panels 210 to perform this beamforming communication. That is, each panel 210 can be located at different positions, orientations, etc., of UE 205. Panels 210 implemented at UE 205 can have the same or different capabilities relative to other panels 210. Each panel 210 can support beamforming communication using one or more transmit and / or receive beams of UE 205. That is, each panel 210 can include one or more antennas, antenna ports, can support multiple different antenna configurations, can support multiple different beamforming configurations, etc. Therefore, each panel 210 can be configured to provide or otherwise support one or more transmit and / or one or more receive beams of UE 205. Therefore, for each configured panel 210, the UE 205 may be equipped with or otherwise support the use of a first transmit beam and / or receive beam set using panel 0, a second transmit beam and / or receive beam set using panel 1, etc.

[0094] Typically, beam management for this type of communication involves UE 205 using the respective transmit beams of base stations 215, 220, and / or 225 to measure reference signals transmitted by base stations 215, 220, and / or 225. For example, UE 205 may use different receive beams of UE 205 to measure the signal strength (e.g., RSRP, RSSI, etc.) and / or any other performance metrics (e.g., CQI, SNR, throughput, etc.) of one or more transmit beams of the base stations. UE 205 sends a feedback message to its serving base station (e.g., base station 215 in a non-limiting example), which uses this information to identify the transmit beams of the base stations used for beamforming communication and / or the receive beams of UE 205. However, in some scenarios, this technique may be insufficient to support beam management / optimization.

[0095] For example, wireless communication system 200 can support full-duplex communication between UE 205 and base stations 215, 220, and / or 225. This full-duplex communication can be implemented in the mmW range (e.g., frequency range 2 (FR2)), sub-THz frequency ranges (e.g., frequency range 4 (FR4), such as 140 GHz, etc.). This full-duplex communication can double the capacity of TDD links and provide very low latency. Full-duplex communication can include simultaneous transmission and reception of overlapping, non-overlapping, and / or partially overlapping FDM radio resources.

[0096] One problem that full-duplex communication needs to address is strong self-interference. That is, self-interference can be associated with UE 205 transmitting while receiving (e.g., a signal transmitted from one panel 210 may interfere with the receive beam on the same panel 210 and / or another panel 210). Self-interference can be direct (e.g., a transmission from one panel 210 interferes with the receive beam on that panel 210 and / or another panel 210) and / or indirect (e.g., a transmission from one panel 210 may be reflected or bounced off object 230, for example, the reflected signal interferes with the same panel 210 and / or another panel 210). In some examples, base stations 215, 220, and / or 225 may experience self-interference associated with full-duplex communication (e.g., between the transmit and receive beams of one or more panels included in the respective base stations).

[0097] One technique for mitigating this self-interference includes using beamforming communication to provide spatial separation between the transmit and receive beams. That is, effective beamforming techniques can be used to suppress self-interference to a negligible or at least manageable level. As the number of panels 210 in UE 205 increases, the degree of spatial separation can be further improved, which further supports improved full-duplex communication. For example, enhanced array density (e.g., denser panels 210) can achieve narrower beam structures and a higher number of elements in a small area. Furthermore, efficient implementations can enable UE 205 to simultaneously use multiple UE receive beams to measure the RSRP, RSSI, etc., of the downlink beams. This can result in UE 205 operating multiple receive beams simultaneously and generating an RSRP vector for each UE uplink beam (e.g., each UE receive beam). However, some wireless communication systems may not provide a mechanism for UE 205 to report its self-interference to its serving base station (e.g., base station 215 in this example), which may limit the base station's ability to optimize full-duplex multi-beam communication.

[0098] Therefore, the described aspects of the technology provide multiple mechanisms for UE 205 to report its self-interference beam relationships, which base stations can use to optimize full-duplex multi-beam communication. The described aspects of the technology create a process for measuring and reporting self-interference (e.g., RSRP, SINR, mutual interference, etc.) of multiple UE transmit beams on UE receive beams in frequency ranges such as mmW and sub-THz. Together with joint quasi-co-location (QCL) reporting (e.g., a first set of signal strength metrics corresponding to the base station reference signal), these techniques enable simultaneous multi-beam operation in full-duplex communication, forming multiple transmit / receive point (TRP) connections.

[0099] For example, UE 205 may use its receive beams to identify a first set of signal strength metrics for the signal strength of the base station's transmit beams. For example, UE 205 may measure the signal strength of a reference signal transmitted by the base station using each or a subset of transmit beams in the base station's transmit beam set. This measurement may be based on each of the UE's receive beams (e.g., the signal strength of the base station's transmit beams measured by multiple UE receive beams). That is, UE 205 may measure the reference signal transmitted by some or all of the transmit beams of base stations 215, 220, and / or 225. In some aspects, UE 205 may measure the reference signal transmitted by the base station using a subset of the transmit beams available at each base station (e.g., using transmit beams pointing towards the location of UE 205 and / or its vicinity). UE 205 may perform such measurements simultaneously using some or all of its receive beams. For example, UE 205 may utilize one or more receive beams on one or more panels 210 to simultaneously measure reference signal transmission. Therefore, the measurement results may include a first set of signal strength metrics for each base station transmit beam / UE receive beam pair, which may include RSRP, RSSI, CQI, SNR, signal-to-noise-plus-interference ratio (SINR), etc.

[0100] Therefore, UE 205 can leverage the low complexity, low power (mmW), sub-THz, etc., that the array (e.g., panel 210) can simultaneously operate multiple of its receive beams to sense transmit beams (e.g., measure reference signal transmissions from base stations 215, 220, and / or 225). Examples of reference signal transmissions include, but are not limited to, CSI-RS, beam management reference signals, tracking reference signals, synchronization signals, information block signals, etc. Base station 215 can send or otherwise transmit configuration signals (e.g., RRC signals, MAC CE, DCI, etc.) to UE 205 identifying resources used for reference signal transmissions. This allows UE 205 to identify or otherwise determine spatially separated base stations (e.g., such as base station 215, base station 220, and / or base station 225). For each transmitted base station beam (e.g., for each transmit beam of a base station), UE 205 can measure the RSRP vector of multiple UE receive beams. By using the last reference signal transmission of the base station's transmit beam, UE 205 can maintain and report an RSRP matrix reflecting all receive / transmit coupling options (e.g., a base station interference table indicating information associated with the signal strength of each base station transmit beam / UE receive beam pair). That is, as the base stations cycle through their transmit beams used for reference signal transmission, UE 205 can construct a table including the RSRP vector of each base station transmit beam for each of UE 205's receive beams. This table can form or otherwise define a first set of signal strength metrics for the signal strength of the transmit beams of the base stations (and / or multiple base stations) using UE 205's receive beams. Therefore, UE 205 can generate a base station-to-UE interference table that includes the corresponding signal strength of each transmit beam in the base station's transmit beam set for each receive beam in UE 205's receive beam set.

[0101] UE 205 may also use a second set of signal strength metrics to identify the signal strength of the transmit beams of UE 205 using the receive beams of UE 205. For example, UE 205 may measure the signal strength of a reference signal transmitted by UE 205 via each transmit beam in the set of transmit beams of UE 205. The reference signal transmitted by UE 205 may be each UE transmit beam of each panel 210. This measurement may be based on each receive beam of UE 205, and the second set of signal strength metrics may be based on the result of this measurement. For example, base station 215 may send or otherwise transmit configuration signals (e.g., RRC signaling, MAC CE, DCI, etc.) to UE 205 identifying resources used for such reference signal transmission. An example of signaling may include a CSI report configuration message.

[0102] Therefore, base station 215 (in this example) can configure resources for self-interference measurement for a full-duplex UE 205 with a set of radio resources (e.g., time, frequency, space, code, etc.). Resources can support various UE transmit beams of panel 210. In some examples, UE 205 and base station 215 can negotiate / configure the number of UE transmit beams / panels 210 to be used for measurement. UE 205 measures self-interference in a specified scenario of simultaneous transmission and reception. That is, UE 205 can perform reference signal transmission using one or more transmit beams of UE 205, while simultaneously measuring reference signal transmission using one or more receive beams of UE 205. This allows UE 205 to find or otherwise identify spatially separated UE transmit and receive beams. For example, for each reference signal transmitted on a UE transmit beam, UE 205 can use the receive beam to measure vectors such as RSRP, SINR, RSSI, and mutual interference of multiple UE receive beams. By using the last reference signal transmission of the UE transmit beam, UE 205 can maintain and report matrices such as RSRP and RSSI that reflect all UE transmit / receive beam pair / coupling options. Therefore, UE 205 can generate a UE self-interference table, which includes the corresponding signal strength or information associated with that signal strength for each transmit beam in the UE 205's transmit beam set for each receive beam in the UE 205's receive beam set. In some examples, each of base stations 215, 220, and / or 225 can generate a base station self-interference table based on simultaneously transmitting a reference signal using the transmit beam and measuring the reference signal transmission using the receive beam. This base station self-interference table includes the corresponding signal strength or information associated with that signal strength for each transmit beam in the base station's transmit beam set for each receive beam in the base station's receive beam set.

[0103] UE 205 may send or otherwise communicate indications of a first signal strength metric set and a second signal strength metric set to, for example, base station 215, which base station 215 may use to select one or more transmit beams for communicating with UE 205. In some aspects, this may include UE 205 sending the corresponding signal strength (e.g., RSRP, RSSI, CQI, etc.) when sending or otherwise providing indications of the first and second signal strength metric sets. For example, UE 205 may simply send the measured signal strength values ​​along with an indication of transmit / receive beam coupling to base station 215.

[0104] In some examples, UE 205 may send an indication of whether the corresponding signal strength meets a threshold for each transmit / receive beam coupling. For example, UE 205 may measure the reference signal transmission from base station 215 when identifying a first signal strength metric set, and measure the reference signal transmission from UE 205 when identifying a second signal strength metric set. UE 205 may compare the measured signal strength with a threshold (e.g., a defined RSRP value) to determine which measurements meet the threshold and which do not. When sending an indication of the first and second signal strength metric sets to base station 215, UE 205 may send a flag (e.g., a bit) set to indicate that the threshold is met and / or set to indicate that the threshold is not met (e.g., failure to meet the threshold).

[0105] Base station 215 (in this example) can use a first set of signal strength metrics (e.g., base station interference metrics) and a second set of signal strength metrics (e.g., UE self-interference metrics) for link and / or beam management / optimization. For example, base station 215 can identify which of its transmit beams and / or which of UE 205's transmit beams can support concurrent beamforming communication and select those transmit beams for continuous communication.

[0106] Therefore, UE 205 can report the complete base station inter-beam interference Tx-Rx coupling matrix and the UE self-interference Tx-Rx coupling matrix reflecting all options (e.g., pairing). UE 205 can optionally report a compressed format matrix with one bit for each entry in the table, where a value of 1 indicates interference RSRP, SINR, etc., above a defined threshold (e.g., threshold satisfied). UE 205 can optionally report a diluted matrix based on reasonable assumptions such as uplink beams not interfering with themselves. UE 205 can optionally report a diluted matrix based on reasonable assumptions such as uplink beams not interfering with beams in the same panel (assuming all beams in the panel are used only for uplink or downlink).

[0107] These technologies can leverage the low cost and high efficiency of sub-THz arrays to form full-duplex multi-TRP connections. From the UE's perspective, mutual interference is minimized. Using mutual interference measurements (rather than relying solely on self-interference characteristics) can reflect the sum of internal interference and transient beam reflections from terrain. In frequency duplex, this can even provide feedback at the symbol level and can be used for fast ACK / NACK feedback, beam tracking, etc.

[0108] Figure 3A and Figure 3BAn example of a table configuration 300 supporting full-duplex multi-beam communication for measurement reports is illustrated according to various aspects of this disclosure. In some examples, table configuration 300 may implement aspects of wireless communication systems 100 and / or 200. Aspects of table configuration 300 may be implemented at or by a UE and / or base station, which may be examples of the corresponding devices described herein. Figure 3A Table configuration 300-a illustrates an example of a base station to UE interference table corresponding to or otherwise associated with a first signal strength metric set. Figure 3B Table configuration 300-b illustrates an example of a UE self-interference table corresponding to or otherwise associated with a second signal strength metric set. In some cases, the techniques described herein for generating table configuration 300-b can be adapted and applied by the base station to generate a base station self-interference table.

[0109] As discussed above, the described aspects of the technology provide various mechanisms for a UE to report both base station interference and UE self-interference to its serving base station. For example, the UE can measure the signal strength of a reference signal transmitted by the base station via each transmit beam in the base station's transmit beam set. The measurement can be based on each receive beam of the UE (e.g., the UE can identify the signal strength of the reference signal transmitted on each base station transmit beam and received at each UE receive beam). Based on the measurement results, the UE can use its receive beam to identify a first set of signal strength metrics for the signal strength of the base station's transmit beams. The UE can also measure the signal strength of a reference signal transmitted by the UE via each transmit beam in the UE's transmit beam set. The measurement can be based on each receive beam of the UE (e.g., the UE can identify the signal strength of the reference signal transmitted on each UE transmit beam and received at each UE receive beam). Based on the measurement results, the UE can use its receive beam to identify a second set of signal strength metrics for the signal strength of its transmit beams. The UE can send or otherwise communicate indications of the first and second signal strength metrics to the base station.

[0110] In summary, Figure 3A Table configuration 300-a illustrates an example of the first signal strength metric set, and Figure 3BTable configuration 300-b illustrates an example of a second set of signal strength metrics indicated to a base station. In some examples, the indication may include the actual signal strength of each transmit / receive beam pair. For example, each intersecting row / column may indicate the RSRP value, RSSI, etc., of the corresponding transmit beam (e.g., base station (BS) transmit beam and / or UE transmit beam) and receive beam (e.g., UE receive beam 0 on panel 1, UE receive beam 1 on panel 2, etc.) pair. In some aspects, the signal strength of each indication may also be conveyed in a manner that identifies the transmit / receive beam pair. In one example, the base station and UE may each be aware of each other's capabilities, such that the sequence of signal strengths can be understood to correspond to starting from row 1, column 1 (e.g., it may correspond to BS transmit beam 0 on panel 0, UE receive beam 0), and subsequent signal strengths may be mapped in a left-to-right, top-to-bottom manner or some other known mapping order.

[0111] In another example, each indicated signal strength may be accompanied by an indicator of the transmit / receive beam pair. For instance, the UE may convey explicit information identifying the signal strength and the transmit / receive beam pair. Therefore, the information associated with the base station-to-UE interference table and the UE self-interference table could be the corresponding signal strength.

[0112] In another example, the UE may use bits, fields, flags, etc., indicating whether the corresponding transmit / receive beam pairs meet or fail to meet thresholds to send indications of a first signal strength metric set and a second signal strength message. For example, thresholds such as RSRP levels, interference levels, throughput rates, etc., can be negotiated / configured between the UE and the base station. The UE may perform measurements to identify the first and second signal strength metric sets and compare the corresponding signal strengths to the thresholds. When sending indications of the first and second signal strength metric sets, the UE may configure or otherwise convey indications of transmit / receive beam pairs that meet or fail to meet the thresholds (e.g., the measured signal strength meets the RSRP threshold).

[0113] As discussed above, the base station can use the combined information conveyed in the first and second signal strength metric sets to perform link and / or beam management / optimization. That is, the base station can use the first signal strength metric set to identify the performance of each BS transmit beam / UE receive beam pair, and use the second signal strength metric set to identify the performance of each UE transmit beam / UE receive beam pair. Previously, when performing such link and / or beam management / optimization, the base station would only have the base station-UE interference information corresponding to Table Configuration 300-a. However, the described technique enables the base station to also consider UE self-interference as indicated in the second signal strength metric set.

[0114] As an example, the first and / or second set of signal strength metrics may indicate that the UE is using UE transmit beams 2 and 3 on panel 2 to perform uplink transmissions (as illustrated by the forward crosshairs in Table Configuration 300-b), potentially causing strong interference to UE receive beams 0-3 on panels 0 and 1. That is, {Panel, TxBeam} = {2, 2} interferes with {Panel, RxBeam} = {1, 0: 3}, and {Panel, TxBeam} = {2, 3} interferes with {Panel, RxBeam} = {0, 0: 3}. Therefore, the base station and / or the UE may avoid scheduling or otherwise configuring uplink transmissions from the UE on UE panel 2.

[0115] As another example, the first and / or second signal strength metric set can instruct the UE to perform uplink transmissions using the UE transmit beam on panel 0 (as illustrated by the forward crosshairs in Table Configuration 300-b) without interfering with any base station transmit beams on other panels. That is, the UE's {Panel, TxBeam} = {0, 0}, {0, 1}, {0, 3} will not interfere with any downlink beams of the base station. Therefore, the base station and / or the UE can use the UE transmit beam on panel 0 to schedule uplink transmissions.

[0116] As another example, the first and / or second signal strength metric set can indicate uplink transmission interference from the UE on {Panel, TxBeam} = {0, 2}, specifically with base station transmit beams 0 and 7, and UE transmit beams {Panel, TxBeam} = {1, 2}, {2, 3}. Therefore, the base station and / or UE can avoid scheduling uplink transmissions using UE transmit beam 2 on panel 0.

[0117] While the described techniques generally relate to base stations and UEs performing link and / or beam management / optimization, it should be understood that the base station can receive similar information from other UEs (e.g., from a second UE) and use this information for more comprehensive link and / or beam management / optimization, in addition to the first and second signal strength metric sets. For example, the base station can receive from the second UE an indication of a third signal strength metric set of the signal strength of the transmit beam of a base station using the second UE's receive beam, and a fourth signal strength metric set of the signal strength of the transmit beam of the second UE using the second UE's receive beam. That is, the second UE (and the third, fourth, etc.) can identify its own base station-to-UE interference table and UE self-interference table and provide this information to the base station. The base station can collect such information from multiple UEs and use the interference information when selecting the beam used for communication with each UE (e.g., the base station transmit beam, the UE receive beam, the UE transmit beam, or any combination thereof).

[0118] Figure 4 An example of a table configuration 400 supporting full-duplex multi-beam communication for measurement reporting is illustrated according to various aspects of this disclosure. In some examples, table configuration 400 may implement aspects of wireless communication systems 100 and / or 200 and / or table configuration 300. Aspects of table configuration 400 may be implemented at or by a UE and / or base station, which may be examples of the corresponding devices described herein. Generally, table configuration 400 illustrates how to use... Figure 3A Table configuration 300-a and Figure 3B The 300-b table configuration allows you to select an example of a beam for link and / or beam management / optimization.

[0119] As discussed above, the described aspects of the technology provide various mechanisms for a UE to report both base station interference and UE self-interference to its serving base station. For example, the UE can measure the signal strength of a reference signal transmitted by the base station via each transmit beam in the base station's transmit beam set. The measurement can be based on each receive beam of the UE (e.g., the UE can identify the signal strength of the reference signal transmitted on each base station transmit beam and received at each UE receive beam). Based on the measurement results, the UE can use its receive beam to identify a first set of signal strength metrics for the signal strength of the base station's transmit beams. The UE can also measure the signal strength of a reference signal transmitted by the UE via each transmit beam in the UE's transmit beam set. The measurement can be based on each receive beam of the UE (e.g., the UE can identify the signal strength of the reference signal transmitted on each UE transmit beam and received at each UE receive beam). Based on the measurement results, the UE can use its receive beam to identify a second set of signal strength metrics for the signal strength of its transmit beams. The UE can send or otherwise communicate indications of the first and second signal strength metrics to the base station.

[0120] In summary, Table Configuration 400 illustrates an example of optimizing a link using the base station-to-UE interference and UE self-interference matrix / table illustrated in Table Configuration 300. Specifically, the table configuration identifies and cross-associates uplink markers (↑), downlink markers (↓), and interference (χ) between a first signal strength metric set and a second signal strength metric set. As discussed above, in some examples, the indication may include the actual signal strength of each transmit / receive beam pair and / or may use bits, fields, flags, etc., indicating whether the corresponding transmit / receive beam pair meets or fails to meet a threshold.

[0121] The base station can use combined information conveyed in a first signal strength metric set and a second signal strength metric set for link and / or beam management / optimization. That is, the base station can use the first signal strength metric set to identify the performance of each BS transmit beam / UE receive beam pair, and use the second signal strength metric set to identify the performance of each UE transmit beam / UE receive beam pair. In the example illustrated in Table Configuration 400, this can instruct the UE to use UE{Panel, TxBeam} = {0, 0}, {0, 1}, {0, 3} to perform uplink transmissions that interfere with the base station's transmit beams 0, 2, and 4. Therefore, when downlink transmissions are scheduled to the UE and / or other UEs, base station transmit beams 0, 2, and 4 can be avoided. This can also indicate that base station transmit beams 3 and 5 can be used without any corresponding or unacceptable interference being introduced into the UE self-interference table. Therefore, downlink transmissions from the base station using transmit beams 3 and 5 can be identified as supported for beamforming communication. This can also instruct the UE to perform uplink transmissions using the UE transmit beam 0 on UE panel 0, introducing unacceptable UE interference and / or base station interference. Therefore, the base station and / or UE can avoid such transmissions to mitigate interference.

[0122] Therefore, when performing link and / or beam management / optimization, the base station may consider uplink marking, downlink marking, and / or interference marking. For example, the base station may select specific base station transmit beams, UE transmit beams, and / or UE receive beams (e.g., on a per-panel basis) for communication with the UE.

[0240] While aspects of LTE, LTE-A, LTE-A Pro, or NR systems may be described for illustrative purposes, and the terms LTE, LTE-A, LTE-A Pro, or NR may be used in most of the description, the techniques described herein are applicable beyond LTE, LTE-A, LTE-A Pro, or NR networks. For example, the techniques described are applicable to a variety of other wireless communication systems, such as Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, and other systems and radio technologies not explicitly mentioned herein.

[0241] The information and signals described herein can be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout this specification can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or light particles, or any combination thereof.

[0242] The various illustrative blocks and components described herein may be implemented or executed using a general-purpose processor, DSP, ASIC, CPU, FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware component, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but alternatively, the processor may be any processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration).

[0243] The functions described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, these functions can be stored on or transmitted via a computer-readable medium as one or more instructions or code. Other examples and implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwired, or any combination thereof. Features implementing the functions can also be physically located in different locations, including being distributed such that portions of the functions are implemented in different physical locations.

[0244] Computer-readable media includes both non-transitory computer storage media and communication media, with communication media encompassing any medium that facilitates the transfer of a computer program from one place to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media can include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage, disk storage or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store required program code components in the form of instructions or data structures and is accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies (such as infrared, radio, and microwave), then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies (such as infrared, radio, and microwave) are all included in the definition of computer-readable media. As used herein, disks and optical discs include CDs, laser discs, optical discs, DVDs, floppy disks, and Blu-ray discs, where disks typically reproduce data magnetically, while optical discs reproduce data optically using lasers. Combinations of these are also included within the scope of computer-readable media.

[0245] As used herein, including in the claims, the term “and / or” when used in a list of two or more items means that any one of the listed items may be used alone, or any combination of two or more of the listed items may be used. For example, if a component is described as containing components A, B, and / or C, then the component may contain only A; only B; only C; a combination of A and B; a combination of A and C; a combination of B and C; or a combination of A, B, and C. Furthermore, as used herein, including in the claims, the word “or” used in a list of items (e.g., a list of items ending with phrases such as “at least one of…” or “one or more of…”) indicates a separate list, such that a list of, for example, at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase “based on” should not be construed as a reference to a closed set of conditions. For example, an example step described as “based on condition A” may be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used in this article, the phrase “based on” should be interpreted in the same way as the phrase “at least in part”.

[0246] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by a dash immediately following the reference numeral and a second reference numeral to differentiate between similar components. If only the first reference numeral is used in the specification, this specification applies to any similar component having the same first reference numeral, regardless of the second or other subsequent reference numerals.

[0247] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all examples that may be implemented or that are within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," and not "preferred" or "superior to other examples." For the purpose of providing an understanding of the techniques described, the detailed description includes specific details. However, these techniques may be practiced without these specific details. In some instances, well-known structures and devices are shown schematically to avoid obscuring the concepts of the described examples.

[0248] The description herein is provided to enable those skilled in the art to make or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but is to be given the widest scope consistent with the principles and novel features disclosed herein.
