[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 032,906, filed on June 1, 2020, entitled “REFERENCE SIGNAL GROUPING FOR FULL-DUPLEX OPERATION,” and U.S. Non-Provisional Patent Application No. 17 / 303,449, filed on May 28, 2021, entitled “REFERENCE SIGNAL GROUPING FOR FULL-DUPLEX OPERATION,” which are hereby expressly incorporated herein by reference.

[0003] Public domain

[0004] Aspects of the present disclosure generally relate to wireless communications and techniques and apparatus for reference signal (RS) grouping for full-duplex operation.

[0005] background

[0006] 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 promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless network may include several base stations (BSs) that can support communications for several 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, while 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, a gNB, an Access Point (AP), a Radio Head, a Transmit Receiving Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment 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 promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by 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 known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR and other radio access technologies are still useful.

[0031] Detailed Description

[0032] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is independently implemented or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as 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 implemented by one or more elements of the claims.

[0033] 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 can 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.

[0034] It should be noted that while 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 after 5G (e.g., 6G).

[0035] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc. or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, 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, a B node, a gNB, a 5G B node (NB), an access point, a 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.

[0036] 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 subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. 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. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0037] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell 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 via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0038] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay 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.

[0039] 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).

[0040] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0041] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may 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, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, 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), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0042] Some UEs may be considered as machine type communication (MTC) UEs, 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 connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network) via, for example, 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 client equipment (CPE). UE120 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.

[0043] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may 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 may be deployed.

[0044] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. 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.

[0045] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) and / or may communicate using an operating band having a second frequency range (FR2), the first frequency range (FR1) may span 410 MHz to 7.125 GHz, and the second frequency range (FR2) may span 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band 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 otherwise specifically stated, it should be understood that the term sub-"6 GHz" and the like, if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the term "millimeter wave" and the like, if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band 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.

[0046] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described herein. Figure 1 Examples described.

[0047] Figure 2 is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication 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.

[0048] 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, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective 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 upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0049] 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 (DEMODs) 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 where 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, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284 .

[0050] 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.

[0051] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. 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 transmission and / or reception components (such as Figure 2 One or more antenna elements of one or more components).

[0052] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. 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, where 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 antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 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, for example, as described with reference to Figure 5-9 as described.

[0053] 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 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and 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 antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 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, for example, as described with reference to Figure 5-9 as described.

[0054] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of the base station 110 may perform one or more techniques associated with reference signaling (RS) grouping for full-duplex operation, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) may perform or direct e.g. Figure 8 The process of 800 Fig. 9 , 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, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example Figure 8 The process of 800 Fig. 9 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0055] In some aspects, UE 120 may include: means for receiving information indicating whether a reference signal is associated with full-duplex operation; means for receiving the reference signal; means for transmitting feedback based at least in part on the reference signal and the information indicating whether the reference signal is associated with the full-duplex operation; means for receiving a reference signal set on a corresponding beam set; means for determining that the beam set is suitable for full-duplex communication by the UE; means for transmitting information indicating a reference signal identifier set corresponding to the reference signal set based at least in part on the beam set being suitable for full-duplex communication by the UE; means for receiving information indicating a reference signal identifier set associated with a reference signal set transmitted using a second transmit beam set, wherein beams from a first transmit beam set and beams from a second transmit beam set may be jointly used for the full-duplex communication. duplex operation; means for selecting another beam associated with a receive-only condition or a transmit / receive condition for the full-duplex operation; means for selecting another beam associated with a transmit-only condition or a transmit / receive condition for the full-duplex operation; means for selecting another beam associated with a transmit-only condition, a receive-only condition, or a transmit / receive condition for the full-duplex operation; means for determining whether a receive beam corresponding to the reference signal is associated with a transmit-only condition, a receive-only condition, or a transmit / receive condition, wherein the feedback indicates whether the receive beam is associated with the transmit-only condition, the receive-only condition, or the transmit / receive condition, and wherein the feedback is based at least in part on the determination; means for determining whether a receive beam corresponding to the reference signal is associated with a transmit / receive condition, wherein the feedback indicates whether the receive beam is associated with the transmit / receive condition, etc. In some aspects, such means may include a combination of 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 254, MIMO detector 256, receive processor 258, and the like.

[0056] In some aspects, base station 110 may include: means for transmitting information indicating whether a reference signal is associated with full-duplex operation; means for transmitting the reference signal; means for receiving feedback from a UE based at least in part on the reference signal and the information indicating whether the reference signal is associated with the full-duplex operation; means for transmitting a reference signal set on a corresponding beam set; means for receiving information indicating a reference signal identifier set corresponding to the reference signal set based at least in part on the beam set being suitable for full-duplex communication by the UE; means for transmitting information indicating a reference signal identifier set for a reference signal set transmitted using a second transmit beam set, wherein beams from a first transmit beam set and beams from a second transmit beam set may be jointly used for the full-duplex operation, etc. In some aspects, such means may include 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.

[0057] although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functions described above with respect to these blocks may be implemented using a single hardware, software, or combined component or a combination of various components. For example, the functions 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.

[0058] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described herein. Figure 2 Examples described.

[0059] Figure 3 is a diagram illustrating an example 300 of physical channels and reference signals in a wireless network according to the present disclosure. Figure 3 As shown in , a downlink channel and a downlink reference signal may be transmitted from base station 110 to UE 120 , and an uplink channel and an uplink reference signal may be transmitted from UE 120 to base station 110 .

[0060] As shown, downlink channels may include examples such as a physical downlink control channel (PDCCH) carrying downlink control information (DCI), a physical downlink shared channel (PDSCH) carrying downlink data, or a physical broadcast channel (PBCH) carrying system information. In some aspects, PDSCH communications may be scheduled by PDCCH communications. As further shown, uplink channels may include a physical uplink control channel (PUCCH) carrying uplink control information (UCI), a physical uplink shared channel (PUSCH) carrying uplink data, or a physical random access channel (PRACH) for initial network access, as well as other examples. In some aspects, UE 120 may transmit acknowledgement (ACK) or negative acknowledgement (NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) in the UCI on PUCCH and / or PUSCH.

[0061] As further shown, the downlink reference signal may include a synchronization signal block (SSB), a channel state information (CSI) reference signal (CSI-RS), a DMRS, or a phase tracking reference signal (PTRS), among other examples. As also shown, the uplink reference signal may include a sounding reference signal (SRS), a DMRS, or a PTRS, among other examples.

[0062] The SSB may carry information used for initial network acquisition and synchronization, such as PSS, SSS, PBCH, and PBCH DMRS. The SSB is sometimes referred to as a synchronization signal / PBCH (SS / PBCH) block. In some aspects, the base station 110 may transmit multiple SSBs on multiple corresponding beams, and the SSBs may be used for beam selection.

[0063] The CSI-RS may carry information for downlink channel estimation (e.g., downlink CSI acquisition), which may be used for scheduling, link adaptation, or beam management, among other examples. The base station 110 may configure a CSI-RS set for the UE 120, and the UE 120 may measure the configured CSI-RS set. Based at least in part on these measurements, the UE 120 may perform channel estimation and may report channel estimation parameters (e.g., in a CSI report) to the base station 110, such as CQI, precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), layer indicator (LI), rank indicator (RI), or RSRP, among other examples. The base station 110 may use the CSI report to select transmission parameters for downlink communications to the UE 120, such as the number of transmission layers (e.g., rank), precoding matrix (e.g., precoder), MCS, or a refined downlink beam (e.g., using a beam refinement procedure or a beam management process), among other examples.

[0064] DMRS may carry information for estimating a radio channel for demodulating an associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH). The design and mapping of DMRS may be specific to the physical channel that the DMRS is used to estimate. DMRS is UE-specific, may be beamformed, may be restricted to scheduled resources (e.g., rather than transmitted over a wideband), and may be transmitted only when necessary. As shown, DMRS is used for both downlink and uplink communications.

[0065] PTRS can carry information for compensating oscillator phase noise. Typically, phase noise increases with the increase of oscillator carrier frequency. Therefore, PTR can be used at high carrier frequencies (such as millimeter wave frequencies) to mitigate phase noise. PTRS can be used to track the phase of the local oscillator and can suppress phase noise and common phase errors. As shown, PTRS is used for both downlink communications (e.g., on PDSCH) and uplink communications (e.g., on PUSCH).

[0066] The SRS may carry information for uplink channel estimation, which may be used for scheduling, link adaptation, precoder selection, or beam management, among other examples. The base station 110 may configure one or more SRS resource sets for the UE 120, and the UE 120 may transmit the SRS on the configured SRS resource sets. The SRS resource sets may have configured uses, such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operation, uplink beam management, and among other examples. The base station 110 may measure the SRS, may perform channel estimation based at least in part on these measurements, and may use the SRS measurements to configure communications with the UE 120.

[0067] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described herein. Figure 3 Examples described.

[0068] Figure 44 is a diagram illustrating an example 400 of full-duplex (FD) zoning, non-FD zoning, and self-interference associated with FD communication according to the present disclosure. As shown, example 400 includes a BS (e.g., BS 110, etc.), UE1 (e.g., UE 120, etc.), and UE2 (e.g., UE 120, etc.). In some aspects, the BS may be capable of FD communication. FD communication may include simultaneous uplink and downlink communications using the same resources. For example, the BS may perform a downlink (DL) transmission to UE1 (shown by reference numeral 410) at least partially overlapping in time using the same frequency resources and may receive an uplink (UL) transmission from UE2 (shown by reference numeral 420).

[0069] As indicated by reference numeral 430, DL transmissions from the BS may self-interfere with UL transmissions to the BS. This may be caused by various factors, such as higher transmit power used for DL ​​transmissions (compared to UL transmissions), radio frequency bleed, etc. In addition, as indicated by reference numeral 440, UL transmissions from UE2 to the BS may interfere with DL transmissions from the BS to UE1, thereby degrading DL performance of UE1.

[0070] FD zoning is shown by reference numeral 450 and non-FD zoning is shown by reference numeral 460. "FD zoning" may refer to a time period and / or frequency region in which a wireless communication device (e.g., BS 110, UE 120, node, wireless communication device, etc.) performs FD communication, and "non-FD zoning" may refer to a time period and / or frequency region in which a wireless communication device performs non-FD (e.g., half-duplex) communication. Compared to non-FD zoning, FD zoning may be associated with higher self-interference and, therefore, associated with a lower signal to interference plus noise ratio (SINR). In some cases, flexible time division duplexing (TDD) may be used to implement FD communication. For example, the configuration of uplink transmission and downlink reception (e.g., antenna panels used for such uplink transmission and downlink reception, respective proportions of downlink and uplink traffic, downlink-only or uplink-only operation, etc.) may change over time.

[0071] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described herein. Figure 4 Examples described.

[0072] The base station may transmit reference signals using different transmit beams to facilitate beam selection, reselection, etc. by the UE. For example, the UE may perform measurements on the reference signal (e.g., layer 1 reference signal received power (L1-RSRP) measurement, L1 signal to interference plus noise ratio (L1-SINR) measurement, etc.). The UE may select one or more beams for communicating with the base station and may report information indicating the one or more selected beams. For example, the UE may select the beam set associated with the highest measurement value and may report a reference signal identifier corresponding to the reference signal transmitted on the beam set.

[0073] In some aspects, the UE may select a beam for FD operation. For example, the UE may select a downlink beam for downlink reception (i.e., a receive beam), and may select another downlink beam for uplink transmission (i.e., a transmit beam) performed concurrently with the downlink reception. Communication performed by a UE or a base station in FD may be referred to as FD operation. However, not all downlink beams carrying reference signals are suitable for FD communication. For example, if the UE were to select a first beam and a second beam transmitted by the same antenna panel of a base station, the base station may not be able to achieve spatial diversity for the first beam and the second beam, making FD communication impractical or suboptimal due to self-interference at the base station. As another example, two reported reference signals may be associated with one or more UE receive beams that cannot be used for FD communication, for example, because the two reference signals are associated with the same UE receive beam, different UE receive beams on the same antenna panel, or a UE receive beam that cannot be used for uplink transmission of the UE. As a third example, the UE may select and report a first beam and a second beam that cannot be used by the base station for reception, which means that FD communication cannot be performed using only the first beam and the second beam. Selecting a beam that is incompatible with FD communication may waste time and resources associated with beam selection and reporting, and may result in interruption of traffic to be communicated as part of the FD communication.

[0074] Some techniques and apparatus described herein provide indications of reference signal grouping based at least in part on the FD capabilities of the transmitter of the reference signal. For example, the transmitter may provide information indicating that a reference signal set is to be used for beam selection for FD operation, thereby enabling the UE to select the reference signal on a beam compatible with the FD operation performed by the UE. As another example, the transmitter may provide information indicating reference signals transmitted on a beam set, which may be used jointly for FD operation (e.g., any pair of beams selected from the beam set are suitable for FD operation). As yet another example, the transmitter may provide information indicating reference signals transmitted on a beam set that cannot be used jointly for FD operation. In such cases, beams corresponding to different beam sets may be used for FD operation. As yet another example, the transmitter may provide information indicating whether the beam used to transmit the reference signal can be used as or preferably used as a receive-only beam, a transmit-only beam, or a transmit and / or receive (transmit / receive) beam. Some techniques and apparatus described herein provide for a UE to indicate whether a receive beam associated with a reported reference signal identifier can be used or preferably used as a receive-only beam, a transmit-only beam, or a transmit or receive (transmit / receive) beam.

[0075] By providing information indicating whether a beam is available for FD operation, the transmitter (e.g., base station) facilitates the UE's selection of a beam for FD operation. Therefore, the efficiency and accuracy of selecting a beam for FD operation are improved, thereby increasing throughput and reducing interference and traffic interruption at the UE and the transmitter. Figure 5 is a diagram illustrating an example 500 associated with reference signal grouping for FD operation according to the present disclosure. Figure 5 As shown in , base station 110 and UE 120 can communicate with each other. In example 500, the base station can be considered as a transmitter because the base station transmits a reference signal set on a corresponding beam set. However, the technology described with respect to example 500 can be applied to any transmitter capable of transmitting a reference signal, such as another UE in a sidelink operation.

[0076] As shown, BS 110 may transmit, and UE 120 may receive, information 510 indicating whether an RS is associated with FD operation. For example, information 510 may indicate whether a transmit beam used by BS 110 to transmit a reference signal may be selected by UE 120 for FD operation. In some aspects, BS 110 may transmit information 510 for a plurality of RSs to be transmitted on corresponding beams. Thus, UE 120 may select a plurality of beams for FD operation based at least in part on information 510.

[0077] In some aspects, BS 110 may provide information 510 in an RS resource configuration (also referred to as a reference signal configuration) for multiple RSs, such as a CSI-ResourceConfig configuration. In other aspects, BS 110 may provide information 510 in an RS-specific configuration (e.g., an individual RS resource configuration), such as a non-zero power channel state information reference signal (NZP-CSI-RS) resource configuration.

[0078] In some aspects, the information 510 may indicate that the purpose of the RS is for FD beam selection. For example, the information 510 may indicate that the beam used to transmit the RS can be used by the BS 110 for FD operation (e.g., the beam can be used as a transmit beam at the BS 110 and a receive beam at the BS 110). In this case, the information 510 may be configured in an RS resource configuration (e.g., CSI-ResourceConfig, etc.) for a plurality of RSs that can be used or selected for FD operation.

[0079] In some aspects, the information 510 may indicate a set of RSs (e.g., a group of RSs) from which multiple beams may be selected for FD operation. For example, the information 510 may indicate a set of two or more RSs, and all subsets of the RSs in these two or more RSs may be transmitted on beams that may be used by the BS 110 for FD operation. Figure 6 6 is a diagram illustrating an example 600 of an RS group for FD beam selection according to the present disclosure. As shown, example 600 includes RS group 1 and RS group 2, the RS group 1 including RS 1, 2, 3, and 4 and the RS group 2 including RS 5, 6, 7, and 8. Any subset of RSs configured in RS group 1 (e.g., RS 1 and RS 2, RS 1 and RS 3, RS 1 and RS 4, RS 2 and RS 3, RS 2 and RS 4, or RS 3 and RS 4, as shown by reference numeral 610) may be used for FD operation of BS 110, and any subset of RSs configured in RS group 2 may be used for FD operation of BS 110. For example, the RSs in the RS group may transmit using beams associated with different TRPs or different antenna panels so that any pair of RSs in the RS group may be selected for FD operation. These RS groups may be indicated as part of the RS resource configuration for the RS group.

[0080] In some aspects, RSs selected from different RS groups may not be available for FD operation (e.g., may not be guaranteed to be available for the FD operation), as shown by reference numeral 620. For example, RSs selected from different RS groups may be associated with the same TRP, the same antenna panel, the same transmit beam at BS 110, etc., which may make these RSs impractical for FD operation.

[0081] In some aspects, the information 510 may indicate a set of RSs (e.g., a group of RSs), and beams may be selected from different RS sets for FD operation. For example, the information 510 may indicate two or more sets of one or more RSs. A beam selected from a first RS set and a beam selected from a second RS set may be used for FD operation, while two beams selected from a single RS set may not be used for FD operation. Figure 7 7 is a diagram illustrating an example 700 of an RS group for FD beam selection according to the present disclosure. As shown, example 700 includes RS group 1 and RS group 2, the RS group 1 including RS 1, 2, 3, and 4 and the RS group 2 including RS 5, 6, 7, and 8. A subset of RSs configured in RS group 1 may be used or not used for FD operations performed by BS 110, and a subset of RSs configured in RS group 2 may be used or not used for FD operations of BS 110, as indicated by reference numeral 710. For example, RSs in an RS group may transmit using beams associated with the same TRP or the same antenna panel so that the RSs in the RS group may not be suitable for FD operations. As indicated by reference numeral 720, RSs selected from different RS groups may be used for FD operations. For example, the FD group may be configured such that RSs from different FD groups are associated with different TRPs or different antenna panels and are therefore selectable for FD operations.

[0082] In some aspects, the information 510 may indicate whether the beam used to transmit the RS is associated with a receive-only condition, a transmit-only condition, or a transmit or receive (transmit / receive) condition. The receive-only condition may indicate that the transmit beam used to transmit the RS is only capable of receiving data communication or is preferably used to receive data communication. The transmit-only condition may indicate that the transmit beam used to transmit the RS is only capable of transmitting data communication or control communication, or is preferably used to transmit data communication or control communication. The transmit / receive condition may indicate that the transmit beam used to transmit the RS is capable of receiving and transmitting data communication or control communication. The UE 120 may select a beam set for FD operation based at least in part on whether the beam set is associated with a receive-only condition, a transmit-only condition, or a transmit / receive condition. For example, the UE 120 may select a pair of beams each associated with a transmit / receive condition, a first beam associated with a transmit-only condition, and a second beam associated with a receive-only condition, etc. For an RS whose transmit beam is associated with a transmit-only condition, the UE 120 may select a corresponding UE beam that is at least capable of reception (e.g., a UE beam associated with a receive-only condition or a transmit / receive condition). For an RS whose transmit beam is associated with a reception-only condition, UE 120 may select a corresponding UE beam capable of at least transmission (e.g., a UE beam associated with a transmission-only condition or a transmission / reception condition). For an RS whose transmit beam is associated with a transmission / reception condition, UE 120 may select a corresponding UE beam associated with a reception-only condition, a transmission-only condition, or a transmission / reception condition.

[0083] return Figure 5 , as indicated by reference numeral 520, BS 110 may transmit a plurality of RSs. For example, BS 110 may transmit a plurality of RSs on a corresponding beam. For example, the RSs may include a CSI-RS, an SSB, a positioning reference signal (PRS), a combination thereof, and the like. As indicated by reference numeral 530, UE 120 may receive a plurality of RSs on a corresponding beam set. For example, UE 120 may generate a receive beam and may receive a plurality of RSs on the generated receive beam.

[0084] As indicated by reference numeral 540, UE 120 may determine feedback for a plurality of RSs. In some aspects, the feedback may indicate measurements for the plurality of RSs, such as L1-RSRP measurements, L1-SINR measurements, etc. In some aspects, the feedback may indicate one or more selected beams. For example, UE 120 may select a beam set based at least in part on measurements performed on the beam set. In some aspects, as indicated by reference numeral 550, UE 120 may select a beam set for FD operation. For example, UE 120 may select a beam set based at least in part on measurements of RSs corresponding to the beam set. In some aspects, UE 120 may select a beam set based at least in part on measurements of RSs corresponding to the beam set. Figure 6 and 7The described RS group is used to select the beam set.

[0085] As indicated by reference numeral 560, UE 120 may transmit, and BS 110 may receive, feedback regarding a plurality of RSs transmitted by BS 110. For example, UE 120 may transmit information indicating a set of RSs selected based at least in part on a measurement of a set of RSs, a set of RSs selected for FD operation based at least in part on information 510 (as indicated by reference numeral 570), and the like.

[0086] In some aspects, as shown by reference numeral 580, the feedback may include information indicating that the receive beam used by the UE 120 to receive the RS associated with the feedback is associated with a transmit-only condition, a receive-only condition, or a transmit-receive condition or is associated with the information. The receive-only condition may indicate that the receive beam used to receive the RS is capable of receiving data communications or control communications or is preferably used to receive data communications or control communications. The transmit-only condition may indicate that the receive beam used to receive the RS is only capable of transmitting control communications or is preferably used to transmit control communications. The transmit / receive condition may indicate that the receive beam used to receive the RS is capable of receiving and transmitting data communications or control communications. In some aspects, the feedback shown by reference numeral 580 may indicate whether the receive beam is associated with a transmit / receive condition, a receive-only condition, or a transmit-receive condition based at least in part on whether the RS is received via a receive beam associated with the transmit / receive condition.

[0087] As indicated by reference numeral 590, the UE 120 and the BS 110 may communicate using the selected beam indicated by reference numeral 570. For example, the UE 120 and the BS 110 may perform FD operation using the selected beam. In this case, the BS 110 may determine whether the selected beam indicated by the UE 120 in the feedback indicated by reference numeral 560 is suitable for FD operation, and if suitable, the selected beam may be configured for FD operation. Therefore, the UE 120 and the BS 110 may select a beam for FD operation based at least in part on the reference signal indicated by reference numeral 520 and the information 510 indicating whether the reference signal indicated by reference numeral 520 is suitable for FD operation. In this way, the possibility of selecting an inappropriate beam for FD operation is reduced, thereby improving throughput and reducing interruptions in communication associated with inappropriate beam selection.

[0088] As indicated above, Figure 5-7 is provided as one or more examples. Other examples may differ from the Figure 5-7 Examples described.

[0089] Figure 8is a diagram illustrating an example process 800 performed, for example, by a UE in accordance with the present disclosure. Example process 800 is an example in which a UE (eg, UE 120, etc.) performs operations associated with reference signal grouping for full-duplex operation.

[0090] like Figure 8 As shown in , in some aspects, process 800 may include receiving information indicating whether the reference signal is associated with full-duplex operation (block 810). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive information indicating whether the reference signal is associated with full-duplex operation, as described above.

[0091] As in Figure 8 As further shown in FIG. 8 , in some aspects, process 800 may include receiving the reference signal (block 820). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive the reference signal as described above.

[0092] As Figure 8 As further shown in FIG. 8 , in some aspects, process 800 may include transmitting feedback based at least in part on the reference signal and the information indicating whether the reference signal is associated with full-duplex operation (block 830). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may transmit feedback based at least in part on the reference signal and the information indicating whether the reference signal is associated with full-duplex operation, as described above.

[0103] In a tenth aspect, either alone or in combination with one or more of the first to ninth aspects, the information indicating whether the reference signal is associated with full-duplex operation is indicated in reference signal configurations each of which is specific to a corresponding reference signal in the reference signal set.

[0104] In an eleventh aspect, alone or in combination with one or more of the first to tenth aspects, the information indicating whether the reference signal is associated with full-duplex operation indicates a reference signal set transmitted using a set of transmit beams that cannot be jointly used for full-duplex operation.

[0107] In a fourteenth aspect, alone or in combination with one or more of the first to thirteenth aspects, the information indicating whether the reference signal is associated with full-duplex operation is indicated in a reference signal configuration for the reference signal set.

[0109] In the sixteenth aspect, alone or in combination with one or more of the first to fifteenth aspects, the information indicating whether the reference signal is associated with full-duplex operation indicates whether the beam corresponding to the reference signal is associated with a transmit-only condition, a receive-only condition, or a transmit / receive condition.

[0110] In a seventeenth aspect, alone or in combination with one or more of the first to sixteenth aspects, process 800 includes selecting another beam associated with a receive-only condition or a transmit / receive condition for the full-duplex operation.
