[0002] This patent application claims priority to the following applications: U.S. Provisional Patent Application No. 63 / 021,425, filed on May 7, 2020, entitled “BEAMPAIR SELECTION USING UPLINK AND DOWNLINK MEASUREMENTS”; and U.S. Non-Provisional Patent Application No. 17 / 302,517, filed on May 5, 2021, entitled “BEAM PAIR SELECTION USING UPLINKAND DOWNLINK MEASUREMENTS”, which are expressly incorporated herein by reference. Technical Field

[0003]

[0006] Generally speaking, aspects of the present disclosure relate to wireless communications and to techniques and apparatus for beam pair selection using uplink and downlink measurements. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that can support communications for multiple user equipments (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, and an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region, and even global level. NR (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) to better integrate with other open standards, as well as supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to grow, it is still useful to further improve LTE, NR and other wireless access technologies.

[0007] Full-duplex (FD) communication refers to simultaneous uplink and downlink communication by a single device using the same resources. FD communication may provide a reduction in latency, enhance spectral efficiency per cell or per UE, and allow for more efficient utilization of resources. Summary of the invention

[0034] The following is a more complete description of various aspects of the present disclosure with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. More specifically, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether the aspect is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, using any number of aspects set forth herein, a device can be implemented or a method can be implemented. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functionality, or structure and functionality other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0035] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0036] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or post-5G (e.g., 6G) RATs.

[0037] Figure 11 is a diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0038] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0039] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0040] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown in , relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, or the like.

[0041] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0042] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0043] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio unit, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0044] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or a connection to a network, for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component and / or a memory component). In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0045] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0046] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, or vehicle-to-infrastructure (V2I) protocol) and / or mesh network. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0047] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) that may span from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2) that may span from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as band center frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless expressly stated otherwise, it should be understood that the terms “sub-6 GHz”, etc. (if used herein) may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or frequency band center frequencies (e.g., greater than 7.125 GHz). Similarly, unless expressly stated otherwise, it should be understood that the terms “millimeter wave”, etc. (if used herein) may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or frequency band center frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and that the techniques described herein are applicable to those modified frequency ranges.

[0048] As pointed out above, Figure 1 is provided as an example. Other examples may differ from those described above. Figure 1 Examples described.

[0049] Figure 2 is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t and the UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0050] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively.

[0051] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMOD) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some aspects, one or more components of UE 120 may be included in housing 284 .

[0052] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0053] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or may be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as Figure 2 One or more antenna elements of one or more components).

[0054] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described with reference to FIGS. 3-13 ).

[0055] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 that schedules the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as described with reference to FIGS. 3-13 ).

[0056] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components in the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in may perform or direct e.g. Fig.12 The process 1200 Fig.13 1300 and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or instruct, for example Fig.12 The process 1200 Fig.13 The operations of process 1300 and / or other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other examples.

[0057] In some aspects, the UE 120 may include: a unit for performing a channel measurement (CM) procedure associated with a self-interference measurement (SIM) procedure in a full-duplex communication mode to determine a downlink signal to self-interference plus noise ratio associated with a downlink (DL) and uplink (UL) (DL / UL) beam pair of the UE; a unit for receiving uplink interference information associated with a UL beam of a DL / UL beam pair of the UE from a base station; a unit for sending a measurement report based at least in part on the CM procedure and the SIM procedure, wherein the measurement report is based at least in part on the downlink signal to self-interference plus noise ratio; a unit for determining an uplink signal to interference plus noise ratio based at least in part on an interference level, wherein the measurement report is based at least in part on the uplink signal to interference plus noise ratio; and a unit for determining an uplink signal to interference plus noise ratio based at least in part on an interference level. A unit for selecting one or more selected DL / UL beam pairs from a plurality of DL / UL beam pairs using one or more selected CMs and SIMs associated with one or more selected DL / UL beam pairs; a unit for receiving configuration information associated with CM and SIM measurement resources for a set of DL / UL beam pairs, wherein the set of DL / UL beam pairs is selected based at least in part on uplink interference information; a unit for determining one or more selected DL / UL beam pairs based at least in part on the uplink interference information; a unit for reporting one or more selected DL / UL beam pairs; a unit for receiving uplink interference information indicating a final DL / UL beam pair selected by a base station; a unit for communicating with a base station using the final DL / UL beam pair in a full-duplex communication mode; etc. In some aspects, such a unit may include a unit for combining Figure 2 One or more components of the UE 120 are depicted, such as a controller / processor 280, a transmit processor 264, a TX MIMO processor 266, a MOD 254, an antenna 252, a DEMOD 254, a MIMO detector 256, a receive processor 258, and the like.

[0058] In some aspects, the base station 110 may include: a unit for determining uplink interference measurements associated with a CM process and a SIM process of a UE for an uplink beam of a DL / UL beam pair of a UE associated with a full-duplex communication mode; a unit for sending uplink interference information to the UE; a unit for receiving a measurement report based at least in part on the CM process and the SIM process; a unit for receiving information indicating a transmit power of the UE; a unit for sending configuration information associated with interference measurement resources for one or more selected DL / UL beam pairs; a unit for receiving a downlink signal to self-interference plus noise ratio from the UE before sending the uplink interference information; a unit for receiving a measurement report indicating one or more selected DL / UL beam pairs based at least in part on the uplink interference information; a unit for sending uplink interference information indicating a final DL / UL beam pair; a unit for selecting a final DL / UL beam pair based at least in part on the uplink interference measurement; a unit for communicating with the UE using the final DL / UL beam pair; etc. In some aspects, such a unit may include a unit for combining Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0059] Although Figure 2 The blocks in the 200 and 210 are shown as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0060] As pointed out above, Figure 2 is provided as an example. Other examples may differ from those described above. Figure 2 Examples described.

[0061] Figure 3A is a diagram illustrating a wireless network 300 operating in a semi-static time division duplex (TDD) configuration. Figure 3Bis a diagram showing a wireless network 320 operating in a dynamic TDD configuration. Dynamic TDD can enhance the spectral efficiency of a wireless communication network and provide higher throughput by dynamically changing the UL or DL ​​transmission direction (e.g., by designating a time slot as a UL time slot or a DL time slot). A UL time slot is a time slot used for uplink communication, such as a time slot configured with at least a threshold number of UL symbols. A DL time slot is a time slot used for downlink communication, such as a time slot configured with at least a threshold number of DL symbols. The TDD UL-DL time slot format for a UE indicates which time slots are UL time slots and which time slots are DL time slots.

[0062] If nearby UEs have different TDD UL-DL time slot formats, one UE (e.g., UE2 308, which may be UE 120) may be a victim and may receive UL transmissions from a UE (e.g., UE1 302, which may be UE 120) called an aggressor. The UL transmission received from UE1 302 is called cross-link interference (CLI). CLI occurs when the UL symbol (e.g., interference symbol) of the aggressor collides with the DL symbol (e.g., interfered symbol) of the victim. CLI may be caused by a UL transmission from an aggressor UE (e.g., UE1 302). The configuration of dynamic TDD can be changed dynamically in response to changes in the traffic pattern. For example, in the case where the traffic pattern is UL heavy, dynamic TDD can identify changes in the traffic pattern and adapt to meet the demand by providing more UL symbols. Alternatively, in the case where the traffic pattern is DL heavy, dynamic TDD can provide more DL symbols to meet the demand.

[0063] exist Figure 3A In FIG. 4 , UE1 302 is located in cell 1 306 and is served by base station 304 (e.g., base station 110), while UE2 308 is located in cell 2 312 and is served by base station 310 (e.g., base station 110). CLI may occur between UEs at the cell edge of nearby cells because UEs at the cell edge of nearby cells may be very close to each other. Figure 3AAs shown, UE1 302 and UE2 308 are located at their respective cell edges and may be communicating with their respective base stations. UE1 302 may be sending an UL transmission 314 to base station 304 while UE2 308 is receiving a DL transmission 316 from base station 310. However, in some cases, UE2 308 may also receive an UL transmission 314 sent by UE1 302 to base station 304 while receiving the DL transmission 316 from base station 310. The UL transmission 314 from UE1 302 received by UE2 308 causes CLI and may interfere with the DL transmission 316 received by UE2 308 from base station 310. As a result, one or more UL symbols of the UL transmission 314 may collide with one or more DL symbols of the DL transmission 316. Figure 3A In the example of , two UL symbols of UL transmission 314 overlap or collide with two DL symbols of DL transmission 316 , such that CLI occurs at the overlap 318 .

[0064] exist Figure 3B In the example of FIG. 1 , both UE1 302 and UE2 308 are served by the same cell (e.g., cell 1 306). Both UE1 302 and UE2 308 are near the cell edge, and in some cases, UE2 308 may also receive UL transmission 314 sent by UE1 302 to base station 304 while receiving DL transmission 316 from base station 304. The UL transmission 314 from UE1 302 received by UE2 causes CLI and may interfere with the DL transmission 316 received by UE2 308 from base station 304. Therefore, one or more UL symbols of the UL transmission 314 may collide with one or more DL symbols of the DL transmission 316.

[0065] CLI measurement metrics include, for example, Sounding Reference Signal Received Power (SRS-RSRP) and CLI Received Signal Strength Indicator (CLI-RSSI). SRS-RSRP may include a linear average of the power contribution of a Sounding Reference Signal (SRS) measured on a configured resource element within a measurement frequency bandwidth considered in a time resource in a configured measurement opportunity. CLI-RSSI may include a linear average of the total received power observed in certain OFDM symbols of a measurement time resource in a measurement bandwidth only on configured resource elements for measurements performed by the UE. For both SRS-RSRP and CLI-RSSI measurement reports, both events may be triggered and periodic reporting is supported. Layer 3 (L3) filtering may be applied so that for CLI-RSSI measurements, the UE implementation may determine whether to reset the filtering when a bandwidth part (BWP) is switched. Dedicated measurement gaps may not be required.

[0066] As pointed out above, Figure 3Aand Figure 3B is provided as one or more examples. Other examples may differ from Figure 3A and Figure 3B Examples described.

[0067] Figure 4 4 is a diagram illustrating an example 400 of self-interference measurement based at least in part on channel state information reference signal (CSI-RS) measurement for beam management. Example 400 involves a base station 110 (shown as a gNB) and a UE including a plurality of UE panels (e.g., UE panels 1, 2, and 3, shown by reference numerals 404, 406, and 408, respectively). In general, the beams are Figure 4 The ellipses with given filling represent beams and Figure 4 Two or more ellipses with the same fill at different positions may represent the same receive beam or transmit beam at different times. For example, reference numeral 410 shows a set of CSI-RS sent by base station 110 on a first beam in a set of CSI-RS resources with repetition. The UE may measure the CSI-RS using corresponding receive beams 412, 414, 416, 418, 420, 422. Reference numeral 424 shows a set of CSI-RS sent by base station 110 on a second beam in a set of CSI-RS resources with repetition. Again, the UE may measure the CSI-RS using corresponding receive beams 412, 414, 416, 418, 420, 422.

[0068] As shown in reference numeral 426, the UE may send a CSI-RS report to the base station 110. The CSI-RS report may indicate the top N beams determined based at least in part on measurements performed using the receive beams 412 to 422. In example 400, N is 4, but N is at most 4 in the current specification. The top N beams may be selected based at least in part on one or more metrics described elsewhere herein. Here, 4 CSI-RS beams (not shown) associated with the 4 Rx beams 414, 418, 420, and 422 are selected.

[0069] Reference numeral 428 shows that a self-interference measurement is determined by UE 120 based at least in part on the selected beam. The arrow from the first beam to the second beam may indicate that the first beam sends a reference signal measured using the second beam to determine the self-interference measurement. For example, the arrow shown in reference numeral 430 indicates that an SRS is transmitted using beam 414, which is measured using beam 418 to determine the self-interference measurement of the Tx and Rx beam pair. The SRS may be associated with a set of SRS resources configured with repetition. In example 400, each pair of transmit and receive beams from beams 414, 418, 420, and 422 is measured, except for the beam pair formed by beams 420 and 422 because beams 420 and 422 are associated with the same panel. As shown in reference numeral 432, the UE may send an SRS measurement report indicating the top 2 beam pairs based at least in part on the self-interference measurement determined in conjunction with reference numeral 428.

[0070] As shown at reference numeral 434, in some aspects, the UE may determine the CLI measurement based at least in part on a reference signal associated with the self-interference measurement. For example, the same SRS transmission used to measure the self-interference from beam 414 to beam 418 may be used by the neighbor UE to measure the CLI at panel i of the neighbor UE, as shown at reference numeral 436.

[0071] As pointed out above, Figure 4 is provided as an example. Other examples may differ from those described above. Figure 4 Examples described.

[0072] Figure 5 1 is a diagram illustrating an example 500 of signaling associated with self-interference measurements for a UE and cross-link interference measurements for one or more neighbor UEs. As shown, example 500 includes a BS (e.g., BS 110), a UE (e.g., UE 120), and two neighbor UEs (e.g., UE 120), illustrated as neighbor UE1 and neighbor UE2.

[0073] As shown in reference numeral 505, the BS may provide a resource configuration for SIM to the UE. For example, the resource configuration may be an SRS resource configuration indicating one or more SRSs to be sent by the UE 120. As shown in reference numerals 510 and 515, the BS may provide a resource configuration for CLI measurement to a neighbor UE. For example, the resource configuration for CLI measurement may be associated with an SRS resource configuration for an SRS to be sent by the UE for SIM or share resources with an SRS resource configuration for an SRS to be sent by the UE for SIM. As shown in reference numeral 520, the UE may send an SRS and may perform SIM based at least in part on the SRS. The curved arrow returning from the SRS to the UE indicates that the UE performs SIM on the SRS. As shown in reference numerals 525 and 530, the neighbor UE may perform CLI measurement using the SRS sent by the UE according to the SRS resource configuration.

[0074] As indicated by reference numerals 535 and 540, the neighbor UE may send a measurement report based at least in part on the CLI measurement. For example, the measurement report may include an SRS RSRP report, a CLI RSSI report, etc. In some aspects, as indicated by reference numeral 545, the BS may provide to the UE an indication of one or more beams associated with high CLI measurements (e.g., CLI measurements that meet a threshold) that the UE is to avoid.

[0075] As shown in reference numeral 550, the UE may report the top M cross beams (xbeams) (where M is an integer) with the lowest RSRP of the beams measured by the UE. In some aspects, the top M cross beams may be selected based at least in part on the CLI indication shown in reference numeral 545. As shown in reference numeral 555, the BS may send information indicating the beam pair selection decision. For example, the BS may select a UL / DL beam pair for the UE and may signal the selected UL / DL beam pair to the UE. In some aspects, the BS may select a UL / DL beam pair based at least in part on the CLI measurement feedback shown in reference numerals 535 and 540.

[0076] Figure 6 is a diagram 600 illustrating a beam measurement process. Figure 6Figure 600 includes a base station 110 and a UE including multiple UE panels (e.g., UE panel 1 604, UE panel 2 606, UE panel 3 608). The base station 110 and the UE may be configured to select a CSI-RS beam based at least in part on a beam measurement process (e.g., 610). The beam measurement process 610 may allow the UE panels (e.g., 604, 606, 608) to measure CSI-RS signals from the base station 110 to determine which of the Rx beams on the UE side is best, which may be based at least in part on the DL signal strength measured at the UE panel, and each Rx beam is associated with a Tx CSI-RS beam at the base station. The beam measurement process 610 may allow the base station 110 to send multiple CSI-RS resources to the UE panel in order to measure the DL channel quality or signal strength on the UE side. The UE may send a CSI-RS report to the base station 110 indicating the top Tx beams at the base station, wherein each top Tx beam is associated with a top Rx beam at the UE side. Based at least in part on channel reciprocity, it may be assumed that the top Rx beam is the top Tx beam at the UE panel. In some aspects, the UE may report the top four Tx beams. However, in some aspects, the UE may report more or less than the top four Tx beams. When the top four Tx beams at the UE and their associated top Rx beams are determined, the UE may perform SIM. The UE may also report the top four beams, each with an associated panel ID of the UE, so that the gNB may avoid configuring an intra-panel SIM to save resource overhead.

[0077] To perform SIM, the UE may send a transmission from beam 620 from UE panel 1 604 such that beams 622, 624, and 626 may measure the amount of energy they receive from the transmission from beam 620. The transmission from beam 620 may be an uplink transmission to base station 110, however, during the uplink transmission from beam 620 to base station 110, some energy may be received at beams of other panels. This energy may be due to side lobes or may be based at least in part on the configuration of the other panels. Therefore, beams 622, 624, and 626 may measure the amount of self-interference caused by the transmission from beam 620. This process is repeated for all of the top four beams indicated in the CSI-RS report. For example, beam 622 may send a transmission such that beams 620, 624, and 626 measure the amount of self-interference caused by the transmission from beam 622. Upon completion of the self-interference process and the channel measurement process, the UE may send an indication 636 to the base station 110 in a layer 1 (L1) signal to interference and noise ratio (L1-SINR) report via an actual value or a maximum value plus a difference value of the SINR, indicating the top DL and UL beam pairs of the UE. The DL and UL beam pairs selected as the top DL and UL beam pairs are beams that have passed a selection threshold. In some aspects, the UE may report that no beams pass the threshold, such that there are no feasible beams and / or beam pairs.

[0078] In order to perform self-interference measurement, a modified L1-SINR configuration and process can be used. L1-SINR may include two resource settings, and the first resource setting (which may be provided by a higher layer parameter resourcesForChannelMeasurement) is configured to perform CM via CSI-RS. CM can measure channel quality. The second resource setting (which may be provided by a higher layer parameter csi-IM-ResourcesForInterference or a higher layer parameter nzp-CSI-RS-ResourcesForInterference) is configured to perform interference measurement (IM) via CSI-RS. The modified L1-SINR may be configured to perform the IM process for SIM purposes using SRS instead of CSI-RS. Each CSI-RS resource for a channel measurement resource (CMR) may be associated with an SRS resource for an interference measurement resource (IMR). The number of CSI-RS resources for CM may be equal to the number of SRS resources for IM. CMR may also be reused for the original L1-SINR beam management purpose. In addition, the IMR can also be reused for CLI measurement purposes at the same time to measure cross-link interference at neighbor UEs using the same SRS resources used for SIM. In some aspects, the IMR configuration can be configured to define full Tx power or reduced Tx power. For example, the reduced Tx power can be X dBm or X% based at least in part on the full Tx power. The UE can use this configuration to amplify the calculated SINR accordingly.

[0079] Reference Figure 6 , Figure 600 provides an example of CM and IM using a modified L1-SINR configuration and process. The CM portion includes four CMRs 612, 614, 616, 618, such that the base station 110 is configured to send CSI-RS to each of the top four Rx beams of the UE. For example, CMR 612 may be sent to Rx beam 620 of UE panel 1 604, CMR 614 may be sent to Rx beam 622 of UE panel 2 606, CMR 616 may be sent to Rx beam 624 of UE panel 3 608, and CMR 618 may be sent to Rx beam 626 of UE panel 3 608. The UE may measure the channel quality received at the UE through the corresponding Rx beam. The UE may store the channel quality measurement under the CMR to determine the SINR.

[0080] The IM part includes the same or more resource amounts as the resources in the CM part, so that the CMR is mapped to the corresponding IMR. For example, each CMR is associated with an IMR for interference measurement. Each CMR can also be mapped to multiple IMRs for measuring interference to the same Rx beam as the CMR but transmitted from different beams of different panels of the UE. The IM part includes four IMRs 628, 630, 632, 634 and is mapped to the corresponding CMR. For example, CMR 612 can be mapped to IMR 628, CMR 614 can be mapped to IMR 630, CMR 616 can be mapped to IMR 632, and CMR 618 can be mapped to IMR 634. The IM part allows SIM to be performed. In order to perform SIM, the IMR configures the UE with SRS resources. Each beam in the beam (e.g., 620, 622, 624, 626) can be configured to send SRS. For example, the UE panel may send an SRS when sending an uplink transmission for a SIM. The sent SRS may be used to measure the SIM. In some aspects, the UE panel 1 604 may send an SRS at beam 620 such that beams 622, 624, and 626 may measure the amount of self-interference caused by the transmission from beam 620. The process is repeated for all other beams 622, 624, 626. For example, beam 622 may send a transmission such that beams 620, 624, and 626 may measure the amount of self-interference caused by the transmission from beam 622. Upon completion of the CM and SIM, the SINR may be determined.

[0081] The mapping of CMR and IMR allows the calculation of SINR based at least in part on the results of the CM and IM parts. The SINR can be determined based at least in part on the ratio of the CMR and the corresponding IMR, such as Figure 6 as shown in the table.

[0082] Figure 6 Various aspects of the present invention provide examples of time division multiplexing (TDM) of CM and IM resources such that the CM portion and the IM portion occur at different times. In some aspects, DL timing can be used for CM, while UL timing can be used for IM. In such a case, SINR can be calculated based at least in part on a ratio of CM to IM and noise (e.g., CM / (IM+noise)). When calculating SINR, the UE can report the SINR results to the base station 110. The SINR results can include reporting of top SINR DL and UL beam pairs.

[0083] As pointed out above, Figure 6 is provided as an example. Other examples may differ from those described above. Figure 6 Examples provided.

[0084] Figure 7 700 is a diagram illustrating a CM and an IM using a modified L1-SINR configuration and procedure. Figure 7 In an example of , CM and IM resources are configured in a frequency division multiplexing (FDM) configuration so that CM and IM occur simultaneously. For example, CMR 614 and IMR 630 are shown as being in an FDM configuration. Base station 110 may transmit a CSI-RS to be received by beam 622 of UE panel 2 606, and beam 620 transmits an SRS received by beam 622 of UE panel 2 606. The UE may measure the reception of the CSI-RS and the SRS to determine the SINR of the Rx beam 622. In some aspects, the CM and IM processes under the FDM configuration may experience time misalignment for DL ​​and / or UL reference signals (RS). In some aspects, the UE may utilize DL timing or UL timing for both CM and IM processes occurring simultaneously in the FDM configuration. In aspects utilizing DL timing, the UE may calculate the RSRP of the CSI-RS, and may calculate the partial RSSI of the interference, and then calculate the estimated SINR based at least in part on the CM and IM processes.

[0085] In some aspects, if the Rx and Tx beams are located on the same panel, the SINR may not be determined. Figure 6 , for Rx beam 624 and Tx beam 626, the SINR may not be determined because they are beams in the same panel. However, when configuring SRS resources for IMR, the base station may not know the panel ID. In such aspects, the base station may be configured to indicate whether the UE should still send SRS if the SRS beam and SIM beam are on the same panel. In some aspects, the base station may be configured to indicate whether the UE should still send SRS if the SRS is reused for CLI measurements at neighbor UEs.

[0086] In some aspects, the UE may be configured to indicate that one or more specific beam pairs may be non-feasible beam pairs, such that the SRS beam and the SIM beam are located on the same panel. In some aspects, the UE may be configured to indicate to the UE during the SIM configuration phase that there are one or more non-feasible beam pairs. In response to receiving an indication of a non-feasible beam pair, the base station may update the SIM configuration and skip or prevent the configuration of intra-panel beam measurements, which may help to waste resources. In some aspects, if the UE indicates that there are non-feasible beam pairs, the reported values ​​of such beam pairs may be reported as background interference rather than self-interference values. In some aspects, for example, for SIM, the UE may be configured to report beams with panel IDs in synchronization signal blocks (SSB) / CSI-RS measurements, so that the base station can avoid or skip configuring the intra-panel SIM, which may help to reduce and / or save resource overhead.

[0087] As pointed out above, Figure 7 is provided as an example. Other examples may differ from those described above. Figure 7 Examples described.

[0088] Figures 8A-8C are diagrams illustrating examples 800 , 810 , and 820 of full-duplex (FD) communications. Fig. 8A The example 800 includes UE1 802 and two base stations (eg, TRPs) 804-1, 804-2, wherein UE1 802 is sending UL transmissions to base station 804-1 and is receiving DL transmissions from base station 804-2. Fig. 8A In example 800, FD is enabled for UE1 802, but is not enabled for base stations 804-1 and 804-2. Figure 8B Example 810 includes two UEs (UE1 802-1 and UE2 802-2) and a base station 804, wherein UE1 802-1 is receiving a DL transmission from the base station 804 and UE2 802-2 is sending a UL transmission to the base station 804. Figure 8B In example 810, FD is enabled for base station 804, but is not enabled for UEs UE1 802-1 and UE2 802-2. Figure 8C Example 820 includes UE1 802 and base station 804, wherein UE1 802 is receiving a DL transmission from base station 804 and UE1 802 is sending a UL transmission to base station 804. Figure 8C In example 820 , FD is enabled for both UE1 802 and base station 804 .

[0089] In summary, the present disclosure relates to ways to improve flexible TDD operation to allow FD communications, simultaneous UL / DL transmissions within frequency range 2 (FR2). Flexible TDD capabilities may exist at the base station or the UE or both. For example, for the UE, the UL transmission may come from one antenna panel and the DL reception may be in another antenna panel. FD communications may depend on beam separation of the UL beam and the DL beam at the corresponding antenna panel. Therefore, it is desirable to improve the way in which the selection of the UL beam and the DL beam for FD communications is performed. Utilizing FD communications can provide a reduction in latency, making it possible to receive DL signals in only UL time slots, which can achieve latency savings. In addition, FD communications can enhance the spectral efficiency per cell or per UE, and can allow for more efficient utilization of resources.

[0090] Beam separation of the UL and DL beams helps limit or reduce self-interference that may occur during FD communications. It is desirable to select UL and DL beams on different antenna panels to minimize self-interference. Determining that the UL and DL beams separated on their respective antenna panels can provide reliable FD communications by selecting beam pairs that minimize or reduce self-interference. Therefore, measuring self-interference at the UE may help determine beam pairs of UL and DL beams that may support FD communications.

[0091] As pointed out above, Figures 8A-8C is provided as one or more examples. Other examples may differ from Figures 8A-8C Examples described.

[0092] The FD UE may perform a SIM process in association with a CM process to identify self-interference of transmissions from the FD UE. For example, the FD UE may be configured with resources for a CM process and a SIM process. The CM process may be based at least in part on a determined transmit beam subset of a base station, wherein the CM may be measured at least in part based on a CSI-RS sent from the base station. The SIM process may be based at least in part on SRS. For example, the configuration for the SIM process may configure the UE to scan and transmit SRS from the same Tx beam corresponding to each Rx beam of one of a plurality of different antenna array panels. The configuration for the SIM process may configure the UE to incrementally receive transmitted SRS through other Rx beams associated with a plurality of different panels. For example, as described elsewhere herein, the CM and SIM processes may be performed at least in part based on corresponding CMR and IMR resources.

[0093] The UE and the base station may communicate using beam pairs. The beam pairs may include beam pairs for communication performed by a given device. For example, at BS 110, the beam pairs may include transmit beams (for downlink communication) and receive beams (for uplink communication). Similarly, at UE 120, the beam pairs may include transmit beams for uplink communication and receive beams for downlink communication. UE 120 may determine the beam pair of UE 120 based at least in part on reference signal information (such as TCI status). A beam pair including a downlink beam and an uplink beam is referred to herein as a DL / UL beam pair. A downlink beam is used for transmission from a base station to a UE, and an uplink beam is used for transmission from a UE to a base station.

[0094] The FD UE may provide feedback indicating the results of the CM and SIM processes, such as L1-SINR measurements, SINR reports, etc. For example, the feedback may include one or more SINR values ​​for each Rx beam in the Rx beam subset with the associated Tx beam of the UE and the corresponding Tx and Rx beam IDs or the corresponding CSI-RS IDs or resource IDs. The UE may select the top one or more DL and UL beam pairs based at least in part on the SINR values ​​to perform L1-SINR reporting based at least in part on the actual value or maximum value plus the difference in SINR, wherein the top one or more DL and UL beam pairs pass the threshold. The base station may select a Tx UL beam / Rx DL beam pair with the UE based at least in part on the SINR report received from the UE. However, the SINR report and / or the selection of the UL / DL beam pair may not take into account the conditions at the base station. This may mean that the selected beam pair may provide suboptimal or poor performance at the base station, thereby reducing throughput and consuming computing and communication resources.

[0095] Some techniques and apparatus described herein provide for determining uplink interference measurements (e.g., uplink signal to interference plus noise measurements) to be used to select beams for SINR reporting and / or for communication between an FDUE and a base station. For example, a base station may determine an uplink interference measurement based at least in part on the UE's IMR, the UE's CSI-RS report, or another transmission received from the UE or another UE. In some aspects, the base station may provide an uplink interference measurement to the UE, and the UE may perform an SINR report based at least in part on the uplink interference measurement. In some aspects, the base station may select an UL / DL beam pair based at least in part on the uplink interference measurement. By considering the uplink interference measurement used to select the UL / DL beam pair, performance at the base station is improved, thereby increasing throughput and improving utilization of computing and communication resources.

[0096] Fig. 9 1 is a diagram illustrating an example 900 of a call flow illustrating beam pair selection using uplink and downlink measurements according to the present disclosure. Example 900 includes a BS 110 and a UE 120. BS 110 may provide a cell serving UE 120.

[0097] As shown in the reference numeral 905, BS 110 may perform interference measurements, such as inter-cell interference measurements. In some aspects, interference measurements may be used to determine uplink signal to interference plus noise (SINR) measurements. Interference measurements may include inter-cell interference measurements or intra-cell interference measurements. In some aspects, BS 110 may perform interference measurements in a transparent manner (e.g., without signaling the configuration of uplink interference measurements). In some aspects, BS 110 may allocate dedicated resources (e.g., dedicated CSI-RS resources, etc.) for uplink interference measurements.

[0098] As indicated by reference numeral 910, BS 110 may provide resource configuration for L1-SINR measurement to UE 120. Resource configuration may include resource configuration for CM process 915 and resource configuration for SIM process (associated with performing SIM). CM process 915 may be a process for performing CM. BS 110 may configure UE 120 for CM process 915. CM process 916 may be based at least in part on a determined Tx beam (e.g., DL beam) subset of a base station, wherein CM may be measured based at least in part on a CSI-RS sent from BS 110. In some aspects, the CM process may be part of L1-SINR measurement. UE 120 may perform CM process 915 based at least in part on a determined Rx beam subset. In some aspects, CM process 915 may include performing channel measurement between each Rx beam in a subset of Rx beams having a corresponding antenna array panel in a plurality of different antenna array panels and an associated Tx beam at BS 110.

[0099] BS 110 may also configure UE 120 for SIM process 920. The configuration for SIM process 920 may configure UE 120 to scan through the same Tx (e.g., UL) beam corresponding to each Rx (e.g., DL) beam of one of the multiple different antenna array panels by sending SRS. The configuration for SIM process 920 may configure UE 120 to incrementally receive the transmitted SRS through other Rx beams associated with multiple different panels. In some aspects, each Rx beam of one of the multiple different panels may receive multiple Tx beams. In some aspects, a first resource for configuring a CM process may be associated with a second resource for configuring an IM process. The IM process may include a SIM process, wherein the IMR of the SIM process may be used for CLI measurement at the same time. As part of the SIM process 920, BS 110 may configure UE 120 with a transmission power for sending SRS. The CMR of CM process 915 may be mapped to one or more IMRs to measure multiple interfering Tx beams using the same Rx beam. The Rx beam may be used to receive an associated CSI-RS transmission from a base station for a CM process 915. In some aspects, the CM process 915 may be used for an L1-SINR beam management process.

[0100] In some aspects, the UE 120 may determine the Rx beam subset based at least in part on a beam measurement process. The BS 110 may configure the UE 120 to perform a beam measurement process. Each Rx beam in the Rx beam subset may be associated with one of a plurality of different antenna array panels. The beam measurement process may include receiving an RS from the BS 110 at each Rx beam of the plurality of different antenna array panels, wherein each Rx beam may be associated with a Tx beam from the BS 110. The Rx beam subset may be indicated as a top or best candidate beam selected based at least in part on a beam management process for SRS to be used for scanning the SIM process 920.

[0101] As shown at reference numeral 925, the UE 120 may measure self-interference for at least one pair of DL / UL beams of the Rx beam subset based at least in part on the SRS received in the SIM process 920. For example, reference numeral 930 shows the transmission of the SRS, and the self-interference measurement of the UE 120 is represented by a curved arrow returning from the transmission of the SRS to the UE 120.

[0102] As indicated by reference numeral 935, the UE 120 may determine a downlink self-interference measurement, such as a downlink signal to self-interference plus noise ratio, based at least in part on the results of the CM process 915 and the SIM process 920. The CMR of the CM process 915 may be mapped to one or more IMRs of the SIM process 920. The downlink signal to self-interference plus noise ratio may be determined based at least in part on a pair of CMR and IMR measurements. The UE 120 may select one or more DL / UL beam pairs from the DL / UL beam pairs with the best (e.g., highest) signal to self-interference plus noise ratio. In some aspects, the UE 120 may select M DL / UL beam pairs based at least in part on the SINR, where M ≥ 0.

[0103] As shown in reference numeral 940, BS 110 may perform uplink interference measurements, for example, by measuring UL SRS beam quality simultaneously with one or more IMRs. For example, BS 110 may measure uplink SRS signal strength based at least in part on an SRS transmitted by UE 120 (shown in reference numeral 930). Thus, BS 110 may determine uplink SRS signal strength without configuring additional measurement resources specifically for uplink interference measurements, thereby reducing overhead. As shown in reference numeral 945, BS 110 may determine uplink SINR based at least in part on uplink interference measurements (e.g., based at least in part on interference measurements determined in conjunction with reference numeral 905).

[0104] As indicated by reference numeral 950, in some aspects, BS 110 may provide uplink interference information indicating an uplink SINR to UE 120. In some aspects, BS 110 may provide information indicating an interference level per UL Tx beam of the UE measured by BS 110 to UE 120. If BS 110 provides the information indicating the interference level, UE 120 may determine the uplink signal strength and / or the uplink SINR based at least in part on the transmit power of UE 120 for SRS and a downlink path loss reference signal.

[0105] As indicated by reference numeral 955, UE 120 may perform L1-SINR reporting. For example, UE 120 may send a SINR report to BS 110 indicating SINR results for multiple CMR and IMR pairs. The SINR report may include one or more SINR values ​​for each Rx beam in a subset of Rx beams with an associated Tx beam of the UE and corresponding Tx and Rx beam IDs or corresponding CSI-RS IDs or resource IDs. In some aspects, UE 120 may select the best one or more DL / UL beam pairs based at least in part on a downlink signal to self-interference plus noise ratio and an uplink interference information value. For example, UE 120 may select the best one or more DL / UL beam pairs based at least in part on one or more corresponding CMs and SIMs associated with one or more selected DL / UL beam pairs.

[0106] As indicated by reference numeral 960, in some aspects, the UE 120 may receive from the BS 110 an indication of a selection of a final DL / UL beam pair to be used for communication between the BS 110 and the UE 120 for full-duplex transmission (as indicated by reference numeral 960). In some aspects, the final DL / UL beam pair may be selected from one or more DL / UL beam pairs identified by the L1-SINR report. Thus, the BS 110 may select the final DL / UL beam pair from the one or more DL / UL beam pairs reported by the UE 120. The UE 120 may select one or more DL / UL beam pairs based at least in part on the uplink SINR and the downlink signal to self-interference plus noise ratio. Thus, the selection of the DL / UL beam pair for communication between the BS 110 and the UE 120 is performed at least in part based on DL and UL interference measurements, thereby increasing the likelihood that the final DL / UL beam pair provides acceptable performance at the BS 110. In some aspects, BS 110 and UE 120 may communicate using the final DL / UL beam pair (for simplicity, Fig. 9 not shown).

[0107] As pointed out above, Fig. 9 is provided as an example. Other examples may differ from those described above. Fig. 9 Examples described.

[0108] Fig.101 is a diagram illustrating an example 1000 of a call flow illustrating beam pair selection using uplink and downlink measurements according to the present disclosure. Example 1000 includes a BS 110 and a UE 120. BS 110 may provide a cell serving UE 120. In example 1000, uplink interference measurements are determined prior to a CM procedure and a SIM procedure, and the uplink interference measurements are provided to UE 120 prior to the CM procedure and the SIM procedure.

[0109] As in Fig.10 In some aspects and as indicated by reference numeral 1005, BS 110 may perform (e.g., inter-cell) interference measurements. Fig. 9 905 of the reference numeral 906 to perform inter-cell interference measurement. In some aspects, BS 110 may determine uplink interference measurement based at least in part on the transmit power of UE 120 and layer 1 RSRP of UE 120 that may be provided by UE 120, as shown in reference numeral 1010. For example, UE 120 may provide such information (e.g., transmit power or layer 1 RSRP) in a CSI-RS report. As shown in reference numeral 1015, BS 110 may determine UL signal strength and / or interference measurement using the transmit power of UE 120 and the path loss of UE 120. For example, BS 110 may determine path loss based on a downlink L1-RSRP report of UE 120. As shown in reference numeral 1020, BS 110 may determine UL-SINR based at least in part on the uplink interference measurement and the interference measurement described in conjunction with reference numeral 1005.

[0110] As indicated by reference numeral 1025, in some aspects, BS 110 may provide for L1-SINR measurements (such as for use in conjunction with Fig. 9 In some aspects, the resource configuration may include information identifying the UL-SINR determined in conjunction with reference numeral 1020. In some aspects, the resource configuration may be based at least in part on the UL-SINR. For example, the BS 110 may select a set of UL / DL beam pairs based at least in part on the UL-SINR (e.g., one or more UE Tx beams may be filtered out based at least in part on the UL-SINR value). The UL / DL beam pair set may be associated with an optimal UL-SINR value, an acceptable set of UL-SINR values, a set of UL-SINR values ​​that meet a threshold, and the like. The BS 110 may configure the CM process and the SIM process to be performed on the selected set of UL / DL beam pairs. Therefore, in this case, the UL-SINR may not be explicitly signaled to the UE 120.

[0111] As shown, UE 120 may perform CM and SIM procedures configured in conjunction with reference numeral 1025. As shown in reference numeral 1030, UE 120 may perform L1-SINR reporting based at least in part on the CM and SIM procedures. In some aspects, as shown in reference numeral 1035, UE 120 may determine L1-SINR reporting based at least in part on downlink signal to self-interference plus noise and uplink SINR values. For example, UE 120 may select one or more DL / UL beam pairs based at least in part on a metric of the L1-SINR report, such as a metric defined by max(min(DL signal to self-interference plus noise ratio, UL-SINR)). UE 120 may use the metric when BS 110 has provided UL-SINR to UE 120, for example, in the resource configuration shown in reference numeral 1025.

[0112] In some aspects, as shown in reference numeral 1040, UE 120 may determine L1-SINR reports based at least in part on the filtered beams described in conjunction with reference numeral 1025. For example, UE 120 may determine L1-SINR reports for one or more DL / UL beam pairs selected by BS 110 based at least in part on UL-SINR. In this case, UE 120 may perform L1-SINR reporting based at least in part on the DL signal to self-interference plus noise ratio of the UL-SINR beams that filter out the poor UL-SINR. As shown, BS 110 may provide information indicating the final DL / UL beam pair selection to UE 120. For example, BS 110 may select a final DL / UL beam pair from one or more DL / UL beam pairs identified by the L1-SINR report, and may indicate the final DL / UL beam pair to UE 120. BS 110 and UE 120 may communicate using the final DL / UL beam pair (not shown).

[0113] As pointed out above, Fig.10 is provided as an example. Other examples may differ from those described above. Fig.10 Examples described.

[0114] Fig.111 is a diagram illustrating an example 1100 of a call flow illustrating beam pair selection using uplink and downlink measurements in accordance with the present disclosure. Example 1100 includes a BS 110 and a UE 120. BS 110 may provide a cell serving UE 120. In example 1100, BS 110 may select a final DL / UL beam pair based at least in part on a UL-SINR. In example 1100, BS 110 may not provide a UL-SINR to UE 120, which may save signaling resources associated with providing a UL-SINR to UE 12 and may reduce regulatory impact.

[0115] According to about Fig. 9 Example 900 or Fig.10 The BS 110 may perform a determination of the UL-SINR (shown by reference numeral 1105) by performing any of the operations described in the example 1000. As shown by reference numeral 1110, the BS 110 may store information indicating the UL-SINR. As shown by reference numeral 1115, the BS 110 may select a final DL / UL beam pair based at least in part on the UL-SINR and at least in part on the DL signal to self-interference plus noise ratio reported by the UE 120. Fig. 9 and Fig.10 The determination and reporting of the DL signal to self-interference plus noise ratio are described in more detail. As indicated by reference numeral 1120, BS 110 may send information indicating the final DL / UL beam pair selection to UE 120. Thus, BS 110 may select the final DL / UL beam pair based at least in part on the UL SINR, thereby increasing the throughput and reliability of the DL / UL beam pair.

[0116] As pointed out above, Fig.11 is provided as an example. Other examples may differ from those described above. Fig.11 Examples described.

[0117] Fig.12 1 is a diagram illustrating an example process 1200 performed, for example, by a UE in accordance with the present disclosure. Example process 1200 is an example of a UE (eg, UE 120, etc.) performing operations associated with beam pair selection using uplink and downlink measurements.

[0118] like Fig.12As shown, in some aspects, process 1200 may include: performing a CM process associated with a SIM process in a full-duplex communication mode to determine a downlink signal associated with a DL / UL beam pair of the UE to a self-interference-plus-noise ratio (block 1210). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may perform a CM process associated with a SIM process in a full-duplex communication mode to determine a downlink signal associated with a DL / UL beam pair of the UE to a self-interference-plus-noise ratio, as described above.

[0119] like Fig.12 As further shown, in some aspects, process 1200 may include receiving uplink interference information associated with a UL beam of a DL / UL beam pair of the UE from a base station (block 1220). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive uplink interference information associated with a UL beam of a DL / UL beam pair of the UE from a base station, as described above. In some aspects, the uplink interference information indicates at least one of: an uplink interference measurement determined by the base station, or a final DL / UL beam pair selected by the base station.

[0120] like Fig.12 As further shown, in some aspects, process 1200 may include: sending a measurement report based at least in part on a CM process and a SIM process, wherein the measurement report is based at least in part on a downlink signal to self-interference plus noise ratio (block 1230). For example, a UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) may send a measurement report based at least in part on a CM process and a SIM process, as described above. In some aspects, the measurement report is based at least in part on a downlink signal to self-interference plus noise ratio. In some aspects, if the uplink interference information indicates an uplink interference measurement, the measurement report is based at least in part on the uplink interference information. In some aspects, if the uplink interference information indicates a final DL / UL beam pair, the uplink interference information is received after sending the measurement report.

[0121] Process 1200 may include additional aspects, such as any single aspect or any combination of the aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0122] In the first aspect, uplink interference information is received after performing a CM procedure and a SIM procedure.

[0139] Although Fig.12 An example block diagram of process 1200 is shown, but in some aspects, process 1200 may include Fig.12 The blocks depicted in the process 1200 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 1200. Additionally or alternatively, two or more blocks in the blocks of the process 1200 may be executed in parallel.

[0140] Fig.13 is a diagram illustrating an example process 1300 performed, for example, by a base station in accordance with the present disclosure. Example process 1300 is an example of a base station (eg, a base station, etc.) performing operations associated with beam pair selection using uplink and downlink measurements.

[0141] like Fig.13 As shown, in some aspects, process 1300 may include determining, for an uplink beam of a DL / UL beam pair of a UE associated with a full-duplex communication mode, uplink interference measurements associated with a CM process and a SIM process of the UE (block 1310). For example, a base station (e.g., using controller / processor 240, etc.) may determine, for an uplink beam of a DL / UL beam pair of a UE associated with a full-duplex communication mode, uplink interference measurements associated with a CM process and a SIM process of the UE, as described above.

[0142] like Fig.13 As further shown, in some aspects, process 1300 may include sending uplink interference information to the UE, wherein the uplink interference information indicates at least one of an uplink interference measurement or a final DL / UL beam pair selected by the base station based at least in part on the uplink interference measurement and a downlink signal to self-interference plus noise ratio provided by the UE (block 1320). For example, the base station (e.g., using controller / processor 240, etc.) may send the uplink interference information to the UE. The uplink interference information may indicate at least one of an uplink interference measurement or a final DL / UL beam pair selected by the base station based at least in part on the uplink interference measurement and a downlink signal to self-interference plus noise ratio provided by the UE, as described above.

[0143] Process 1300 may include additional aspects, such as any single aspect or any combination of the aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0144] In a first aspect, process 1300 includes receiving a measurement report based at least in part on a CM process and a SIM process, wherein the measurement report is based at least in part on the CM process and the SIM process, and wherein, if the uplink interference information indicates an uplink interference measurement, the measurement report is based at least in part on the uplink interference information.
