Technical Field

[0003]

[0011] Generally speaking, aspects of the present disclosure relate to wireless communications and to techniques and apparatus for full-duplex downlink and uplink beam pair selection. 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 integrate with other open standards 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), so as to better support mobile broadband Internet access, as well as support 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 time 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. 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, functions, or structures and functions 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 RATs beyond 5G (e.g., 6G).

[0037] Figure 1is 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 to each other and / or to 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 , a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a 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, etc.)), 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, vehicle-to-infrastructure (V2I) protocol, etc.), 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 intermediate 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 by the International Telecommunication Union (ITU) as a “millimeter wave” band. Thus, unless expressly stated otherwise, it should be understood that the term “sub-6 GHz”, etc. (if used herein) may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequencies (e.g., greater than 7.125 GHz). Similarly, unless expressly stated otherwise, it should be understood that the term “millimeter wave”, etc. (if used herein) may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate 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 noted above, Figure 1 is provided as an example. Other examples may differ from those described above. Figure 1 Examples described.

[0049] Figure 2 1 is a diagram illustrating an example of base station 110 communicating with UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and 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 channel quality indicator (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 antennas 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 Figure 9-13 described).

[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 to schedule 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 Figure 9-13 described).

[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, UE 120 may include: a unit for receiving a measurement trigger indicating a set of candidate base station beam pairs from a base station in a full-duplex transmission mode, wherein the candidate base station beam pairs in the set of candidate base station beam pairs are associated with corresponding identified UE beam pairs in the set of identified UE beam pairs and include a base station uplink (UL) beam and a base station downlink (DL) beam, wherein the corresponding identified UE beam pair includes a UE UL beam and a UE DL beam, wherein the set of candidate base station beam pairs is identified at least in part based on a base station self-interference measurement (SIM); a unit for sending a beam measurement report to the base station based at least in part on a plurality of beam measurements, the plurality of beam measurements being obtained at least in part based on the measurement trigger; and so on. In some aspects, such a unit may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 255, MIMO detector 256, receive processor 258, and the like.

[0058] In some aspects, the base station 110 may include: a unit for sending a measurement trigger indicating a set of candidate base station beam pairs to a UE in a full-duplex transmission mode, wherein the candidate base station beam pairs in the set of candidate base station beam pairs are associated with corresponding identified UE beam pairs in the set of identified UE beam pairs and include a base station UL beam and a base station DL beam, wherein the corresponding identified UE beam pair includes a UE UL beam and a UE DL beam, wherein the set of candidate base station beam pairs is identified at least in part based on a base station SIM; a unit for receiving a beam measurement report from the UE based at least in part on a plurality of beam measurements, the plurality of beam measurements being obtained at least in part based on the measurement trigger; and so on.

[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 noted 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 3B302 is a diagram showing a wireless network 320 operating in a dynamic TDD configuration. Dynamic TDD can enhance the spectrum efficiency of a wireless communication network and provide higher throughput by dynamically changing the UL or DL ​​transmission direction. However, if nearby UEs have different TDD UL-DL slot formats, a UE (e.g., UE2 308) can be a victim and can receive UL transmissions from a UE (e.g., UE1 302) called an offender. The UL transmission received from UE1 302 is called cross-link interference (CLI). CLI occurs when the offender's UL symbol (e.g., interference symbol) conflicts with the victim's DL symbol (e.g., interference symbol). CLI may be caused by UL transmissions from an offender UE (e.g., UE1 302). The configuration of dynamic TDD can be changed dynamically in response to changes in business patterns. For example, in the case where the business pattern is UL intensive, dynamic TDD can identify changes in business patterns and adaptively change to meet demand by providing more UL symbols. Alternatively, in the case where the business pattern is DL intensive, dynamic TDD can provide more DL symbols to meet demand.

[0062] exist Figure 3A In the example, UE1 302 is located in cell 1 306 and served by base station 304, while UE2 308 is located in cell 2 312 and served by base station 310. 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 3A As 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 the UL transmission 314 to be received by UE2 308 and may interfere with the DL transmission 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 .

[0063] exist Figure 3BIn 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 UL transmission 314 to interfere with DL transmission 316 received by UE2 308 from base station 304. Therefore, one or more UL symbols of UL transmission 314 may collide with one or more DL symbols of DL transmission 316.

[0064] CLI measurement metrics include 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 the SRS measured on the configured resource elements within the measurement frequency bandwidth considered in the time resources in the configured measurement opportunity. CLI-RSSI may include a linear average of the total received power observed in certain OFDM symbols of the measurement time resources in the measurement bandwidth on the configured resource elements only for UE measurements. For both SRS-RSRP and CLI-RSSI measurement reports, these two events can be triggered and periodic reporting is supported. Layer 3 (L3) filtering can be applied so that for CLI-RSSI measurements, the UE implementation can determine whether to reset the filtering when the bandwidth part (BWP) is switched. Dedicated measurement gaps may not be required.

[0065] As noted above, Figure 3A and 3B is provided as one or more examples. Other examples may differ from Figure 3A and 3B Examples described.

[0066] Figure 4 4 is a diagram illustrating an example 400 of self-interference measurement based at least in part on CSI-RS measurement for beam management. Example 400 involves a base station 402 (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 4Two 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 with repetitions sent by base station 110 on a first beam in a set of channel state information reference signal (CSI-RS) resources. 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 with repetitions sent by base station 402 on a second beam in a set of CSI-RS resources. Again, the UE may measure the CSI-RS using corresponding receive beams 412, 414, 416, 418, 420, 422.

[0067] As indicated by reference numeral 426, the UE may send a CSI-RS report to the base station 402. 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 the example 400, N is 4, but N may be some other number. 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.

[0068] Reference numeral 428 shows that the UE 120 determines a self-interference measurement 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 a sounding reference signal (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.

[0069] As shown at reference numeral 434, in some aspects, the UE may determine a cross-link interference (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 self-interference from beam 414 to beam 418 may be used by a neighbor UE to measure CLI at panel i of the neighbor UE, as shown at reference numeral 436.

[0070] As noted above, Figure 4 is provided as an example. Other examples may differ from those described above. Figure 4 Examples described.

[0071] 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.

[0072] As shown in reference numeral 505, the BS may provide a resource configuration for self-interference measurement (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 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 of the SRS return 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 based on the SRS resource configuration.

[0073] 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 reference signal received power (RSRP) report, a CLI received signal strength indicator (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.

[0074] As shown in reference numeral 550, the UE may report the top M cross beams (xbeam) (M is an integer) with the lowest RSRP 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.

[0075] Figure 6 is a diagram 600 illustrating a beam measurement process. Figure 6 Figure 600 includes a base station 602 and a UE including multiple UE panels (e.g., UE panel 1 604, UE panel 2 606, UE panel 3 608). The base station 602 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 602 to determine which Rx beam is best among the Rx beams on the UE side, 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 602 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 602 indicating the top Tx beam at the base station, wherein each of the top Tx beams 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.

[0076] 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 602, however, during the uplink transmission from beam 620 to base station 602, 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 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, an indication 636 may be sent to the base station 602 in an L1-SINR report via the actual or maximum plus differential 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 the selection threshold. In some aspects, the UE may report that no beams pass the threshold, so that there are no feasible beams and / or beam pairs. The report may indicate, for example, that no beams will be used.

[0077] In order to perform self-interference, a modified layer 1 signal to interference plus noise ratio (L1-SINR) configuration and process can be utilized. L1-SINR may include two resource settings, the first resource setting (which may be provided by a higher layer parameter resourcesForChannelMeasurement) is configured to perform channel measurement (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 utilize SRS instead of CSI-RS to perform the IM process for SIM purposes. 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 used for CM may be equal to the number of SRS resources used for IM. CMR may also be reused for the original L1-SINR beam management purpose. In addition, IMR can also be reused for CLI measurement purposes to simultaneously use the same SRS resources used for SIM to measure CLI at neighbor UEs. 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.

[0078] exist Figure 6 6, diagram 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 602 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 4 608. 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.

[0079] The IM part includes the same number or more resources as 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 using different beams sent from different panels of the UE. The IM part includes four IMRs 628, 630, 632, and 634 mapped to the corresponding CMRs. 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 (e.g., 620, 622, 624, 626) can be configured to send SRS. For example, the UE panel can send SRS when sending uplink transmissions for SIM. The transmitted SRS may be used to measure SIM. In some aspects, the UE panel 604 may transmit 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 transmit 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 CM and SIM, the SINR may be determined.

[0080] 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.

[0081] Figure 6 The example of provides an example of time division multiplexing (TDM) of CM and IM resources, so that the CM part and the IM part occur at different times. In some aspects, DL timing can be used for CM, and UL timing can be used for IM. In such a case, SINR can be calculated based at least in part on the ratio of CM to IM and noise (e.g., CM / (IM+noise)). Based on the calculated SINR, the UE can report the SINR results to the base station 602. The SINR results can include reporting of the top SINR DL and UL beam pairs.

[0082] As noted above, Figure 6 is provided as an example. Other examples may differ from those described above. Figure 6 Examples described.

[0083] Figure 7700 is a diagram illustrating a CM and an IM using a modified L1-SINR configuration and procedure. Figure 7 In an example, 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 in an FDM configuration. Base station 602 may transmit a CSI-RS to be received by beam 622 of UE panel 2 606, and beam 620 transmits an SRS to be 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 of DL and / or UL reference signals (RS). In some aspects, the UE may use 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; the estimated SINR is then calculated based at least in part on the CM and IM processes.

[0084] 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 in the case where the SRS beam and the 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 in the case where the SRS is reused for CLI measurement of neighbor UEs.

[0085] In some aspects, the UE may be configured to indicate that one or more specific beam pairs may be infeasible 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 infeasible beam pairs. In response to receiving an indication of an infeasible beam pair, the base station may update the SIM configuration and skip or prevent the configuration of intra-panel beam measurements, which may result in a waste of resources. In some aspects, if the UE indicates that there are infeasible 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 a SIM, the UE may be configured to indicate a beam associated with a panel ID so that the base station can avoid or skip configuring the intra-panel SIM, which may help to reduce and / or save resource overhead.

[0086] As noted above, Figure 7is provided as an example. Other examples may differ from those described above. Figure 7 Examples described.

[0087] Figures 8A-8C are diagrams illustrating examples 800 , 810 , 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 the example 800 in FIG. 8 , FD is enabled for UE1 802 , but is not enabled for base stations 804 - 1 , 804 - 2 . Figure 8B Example 810 includes two UEs (UE1 802-1 and UE2 802-2) and a base station 804, wherein UE1 802-2 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 .

[0088] In summary, the present disclosure relates to ways to improve flexible time division duplex (TDD) operation to allow FD communication while performing UL / DL transmissions in 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 communication may depend on beam separation of the UL beam and the DL beam at the corresponding antenna panel. In such a case, it is desirable to improve the way in which the selection of the UL beam and the DL beam for FD communication is performed. Utilizing FD communication 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 communication can enhance the spectral efficiency of each cell or each UE and can allow more efficient utilization of resources.

[0089] Beam separation of 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 are separated on their respective antenna panels can provide reliable FD communications by facilitating the selection of 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.

[0090] As noted above, Figures 8A-8C is provided as an example. Other examples may differ from those described above. Figures 8A-8C Examples described.

[0091] A full-duplex (FD) UE may perform a self-interference measurement (SIM) procedure to identify self-interference of transmissions from an FD UE. An FD base station may also perform a SIM procedure to identify self-interference of transmissions from an FD base station. The UE may provide a measurement report to the base station to indicate the results of the UE SIM. The base station may select paired beams (referred to herein as "beam pairs") for use by the UE ("UE beam pairs") and the base station ("base station beam pairs") during FD communications. The beam pairs may include UL beams and DL beams. In some aspects, the beam pairs may include receive (Rx) beams and transmit (Tx) beams. Performing SIM and channel measurements (CM) for all possible beam pairs may be computationally and time intensive.

[0092] Some techniques and devices described herein provide for selecting beam pairs based on measurements performed on less than all possible beam pairs. In some aspects, a base station may indicate a set of candidate base station beam pairs and a corresponding set of identified UE beam pairs to a UE. The UE may perform a SIM associated with the identified UE beam pairs and report the top one or more UE beam pairs to the base station. The base station may select a base station beam pair and a UE beam pair from the candidate base station beam pairs and the one or more UE beam pairs, respectively.
