Description

[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. nonprovisional patent application No. 17 / 009,366, entitled “REFERENCE SIGNAL PORTALLOCATION”, filed on September 1, 2020, which is expressly incorporated herein by reference in its entirety. Technical Field

[0003] Various aspects of this disclosure relate generally to wireless communication, and specifically to techniques and apparatus for allocating reference signal ports. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems 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 collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include several base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with the base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an uplink (or reverse link) refers to the communication link from the UE to the 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] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the municipal, national, regional, and even global levels. NR (also known as 5G) is a set of enhancements to the LTE mobile standard issued by the 3rd Generation Partnership Project (3GPP). NR aims to support mobile broadband internet access by: improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0007] In some aspects, the wireless communication method performed by the UE includes: receiving multiple spatial dimension multiplexing (SDM) communications via a single antenna panel of the UE; and performing phase noise correction for the multiple SDM communications based at least in part on a phase tracking reference signal (PT-RS) received via a single communication among the multiple SDM communications.

[0008] In some aspects, the wireless communication method performed by the base station includes: determining that the UE wants to receive multiple SDM communications associated with multiple transmit-receive points (TRPs) via a single antenna panel of the UE; and configuring a single TRP of the multiple TRPs to transmit PT-RS together with the communications in the multiple SDM communications for the UE to use for phase noise correction of the multiple SDM communications.

[0009] In some aspects, a UE for wireless communication includes a memory; and one or more processors operatively coupled to the memory, the memory and the one or more processors being configured to receive a plurality of SDM communications via a single antenna panel of the UE; and to perform phase noise correction for the plurality of SDM communications based at least in part on PT-RS received via a single of the plurality of SDM communications.

[0010] In some aspects, a base station for wireless communication includes a memory; and one or more processors operatively coupled to the memory, the memory and the processors being configured to determine that a UE will receive multiple SDM communications associated with multiple TRPs via a single antenna panel of the UE; and to configure a single TRP of the multiple TRPs to transmit PT-RS using the communications in the multiple SDM communications so that the UE can use the multiple SDM communications for phase noise correction.

[0011] The aspects generally include methods, apparatus, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication equipment, and processing systems as described herein with reference to the accompanying drawings and description.

[0020] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided to make this disclosure thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of any other aspect of this disclosure or in combination with any additional aspects of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using additional structures, functionalities, or structures and functionalities that supplement or complement the various aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0021] Several aspects of a telecommunications system 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, “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 entire system.

[0022] It should be noted that although the terms commonly associated with 5G or NR Radio Access Technologies (RATs) are used in this document to describe the aspects, the aspects of this disclosure can be applied to other RATs, such as 3G RATs, 4G RATs and / or RATs after 5G (e.g., 6G).

[0023] Figure 1This diagram illustrates an example of a wireless network 100 in accordance with various aspects of this disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network, an LTE network, etc. The wireless network 100 may include several base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, 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 the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0024] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or other types of cells. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and allow restricted access for UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0025] In some respects, the cell need not be stationary, and the geographical area of ​​the cell can move depending on the location of the mobile BS. In some respects, BSs can interconnect with each other and / or interconnect 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, virtual networks using any suitable sending network, etc.).

[0026] The wireless network 100 may also include a relay station. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., a BS or a UE) and transmitting data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, repeater, etc.

[0027] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0028] Network controller 130 can be coupled to a set of Base Stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. These BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0029] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet computer, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0030] Some UEs can be considered 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, instruments, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network, such as the Internet or a cellular network) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered customer premises equipment (CPE). UE 120 can be included within a housing that houses the various components of UE 120, such as processor components, memory components, etc. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, etc.

[0031] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0032] In some respects, 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). For example, UEs 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, vehicle-to-infrastructure (V2I) protocols, mesh networks, etc.). In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by base station 110.

[0033] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1), which can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating band with a second frequency range (FR2), which can span from 24.25 GHz to 52.6 GHz. The 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 generally referred to as the "sub-6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although this is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU). Therefore, unless otherwise specified, it should be understood that the terms "below 6 GHz," if used herein, can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or intermediate band frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise specified, it should be understood that the terms "millimeter wave," if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate band frequencies (e.g., below 24.25 GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0034] As mentioned above, Figure 1 This is provided as an example only. Other examples may differ from this combination. Figure 1 The content described.

[0035] Figure 2 The present disclosure illustrates an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100. The base station 110 may be equipped with T antennas 234a to 234t, while the UE 120 may be equipped with R antennas 252a to 252r, wherein typically, T ≥ 1 and R ≥ 1.

[0036] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and decoding schemes (MCS) for each UE based at least in part on the Channel Quality Indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper-layer signaling notifications, etc.), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS), etc.) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0037] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the received reference signal power (RSRP), received signal strength indicator (RSSI), received reference signal quality (RSRQ), channel quality indicator (CQI), etc. In some respects, one or more components of UE 120 may be included in housing 284.

[0038] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0039] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 can be pre-encoded by the TX MIMO processor 266, where applicable, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to base station 110. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 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 (e.g., as referenced). Figure 4-9 describe).

[0040] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 where applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, base station 110 includes transceiver. Transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receiver processor 238, transmitter processor 220 and / or TXMIMO 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 (e.g., as referenced). Figure 4-9 describe).

[0041] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other component may perform one or more techniques associated with reference signal port allocation, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can execute or direct, for example Figure 6 Process 600 Figure 7 The process 700 and / or other processing described herein. Memory 242 and 282 may store data and program code 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, program code, etc.) 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, translation, interpretation, etc.), may cause one or more processors, UE 120 and / or base station 110 to perform or direct, for example... Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes as described herein. In some aspects, execution instructions may include run instructions, translation instructions, compilation instructions, interpretation instructions, etc.

[0042] In some aspects, UE 120 may include a unit for receiving multiple SDM communications via a single antenna panel of the UE; a unit for performing phase noise correction for the multiple SDM communications based at least in part on PT-RS received via a single communication of the multiple SDM communications; etc. In some aspects, such a module may include a combination of Figure 2 One or more components of the UE120 described, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0043] In some aspects, base station 110 may include elements for determining that the UE will receive multiple SDM communications associated with multiple TRPs via a single antenna panel of the UE; components for configuring a single TRP among the multiple TRPs to transmit PT-RS along with the communications in the multiple SDM communications for phase noise correction by the UE for use by the UE in the multiple SDM communications; etc. In some aspects, such components may include combinations of Figure 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receiver processor 238, controller / processor 240, transmitter processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0044] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above for each box can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described for the transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0045] As mentioned above, Figure 2 This is provided as an example only. Other examples may differ from this combination. Figure 2 The content described.

[0046] Figure 3This is a diagram illustrating an example 300 of communication with multiple transmitting and receiving points according to various aspects of this disclosure. As shown, UE 120 can communicate via a wireless network with TRP group 330 (including TRP 330A, TRP 330B, and TRP 330C), TRP group 335 (including TRP 335A, TRP 335B, and TRP 335C), and TRP group 340 (including TRP 340A and TRP 340B). TRP group 330, TRP group 335, and TRP group 340 can be configured by one or more base stations to communicate with UE 120.

[0047] like Figure 3 As shown, UE 120 can communicate with TRP group 330 via first antenna panel 305, with TRP group 335 via second antenna panel 310, and with TRP group 340 via third antenna panel 315. UE 120 can downsample the signals received at antenna panels 305, 310, and 315 from radio frequency (e.g., carrier frequency) to the intermediate frequency (IF) of each antenna panel. After downsampling the signal at each antenna panel, UE 120 can forward the signal to an IF-to-baseband (BB) converter 320. The IF-to-BB converter 320 can downsample the signal from the IF frequency range to the BB frequency range. UE 120 can forward the signal to one or more BB logic devices 325 to convert the signal into data, control information, etc.

[0048] In some wireless networks (e.g., those using millimeter-range, sub-megahertz-range, etc.), the TRPs of TRP groups 330, 335, and 340 can utilize PT-RS to transmit signals. The UE can use PT-RS to estimate phase noise and remove phase noise from the signal. In this way, the UE can improve the likelihood of decoding the signal.

[0049] For example, when the TRP upsamples the signal information to the RF (e.g., the carrier frequency), it may result in phase noise in the signal. Alternatively, for example, when the UE 120 downsamples the signal to the IF frequency range, it may also result in phase noise in the signal. In some networks, the phase noise of the signal caused by downsampling by the UE 120 may be greater than the phase noise caused by upsampling by the TRP. For example, upsampling the signal may result in -40 dB of phase noise below the carrier frequency, while downsampling the signal may result in -30 dB of phase noise below the carrier frequency.

[0050] In some networks, each TRP can transmit signals to UE 120, where each signal includes a PT-RS, allowing UE 120 to estimate and correct the phase noise of each signal individually. This allows UE 120 to estimate and correct both receiver-induced and transmitter-induced phase noise, improving the likelihood of signal decoding. However, by including a PT-RS in each signal, the TRP can consume communication and network signals that may already be used to carry data. Alternatively, UE 120 can consume computational resources to process the PT-RS, estimate phase noise, and correct the phase noise of each signal.

[0051] As mentioned above, Figure 3 This is provided as an example only. Other examples can be found in the references. Figure 3 The descriptions are different.

[0052] In some aspects described herein, the UE can estimate and correct the phase noise of each UE antenna panel. For example, the UE can estimate the phase noise and apply phase noise correction to multiple signals (e.g., spatially multiplexed signals) received via a single antenna panel of the UE. In some aspects, the UE can estimate the phase noise at least in part based on the PT-RS of a single communication of multiple signals, and then perform phase noise correction on multiple signals at least in part based on the phase noise estimation. In this way, the UE can save computational resources that might otherwise be used to process PT-RS, estimate phase noise, and correct phase noise individually for each signal.

[0053] In some respects, the UE can estimate the phase noise of each antenna panel of the UE based at least in part on the RF-to-IF downsampling of the UE, which is the primary cause of phase noise. In some communications, correction of the phase noise introduced by the UE (e.g., receiver phase noise) by RF-to-IF downsampling may be sufficient to operate with the desired modulation scheme (e.g., 256 quadrature amplitude modulation (QAM), 1K QAM, etc.) without correction of the phase noise introduced by the TRP.

[0054] In some aspects, UE reports can associate Transmission Configuration Indicator (TCI) status identifiers (e.g., for multiple communications) with a single antenna panel. In other words, the UE can indicate a TCI status identifier associated with a single antenna panel. For example, the UE can send a report based on a CRI (CSI-RS Resource Indicator) and the associated antenna panel (e.g., using an antenna panel index) as part of a report, such as beam management procedure communications (e.g., Channel State Information (CSI) Resource Index (CRI) RSRP reports (e.g., CRI-L1-RSRP), CRI Signal-to-Interference-plus-Noise Ratio (SINR) reports (e.g., CRI-L1-SINR), etc.). In this way, the base station can determine which TRPs will transmit signals to the UE via a common antenna panel.

[0055] In some respects, a base station can configure a single TRP out of multiple TRPs that are to transmit signals to a single panel of the UE to transmit the signal along with PT-RS. In this way, the base station can save communication and / or network resources that might otherwise be used to carry PT-RS on each signal of multiple TRPs.

[0056] Figure 4 This is a diagram illustrating an example 400 associated with providing and / or using multi-link capability reporting, based on various aspects of this disclosure. Figure 4 As shown, a base station (e.g., base station 110) can communicate with a UE (e.g., UE 120), one or more TRPs, etc. In some aspects, the base station can communicate with the UE via one or more TRPs. In other words, the base station can configure TRPs to communicate with the UE. The base station, the UE, and one or more TRPs can be part of a wireless network (e.g., wireless network 100).

[0057] As shown by reference numeral 405 in the attached figure, the base station can transmit configuration information, and the UE can receive configuration information. In some aspects, the UE can receive configuration information from another device (e.g., from another base station, another UE, etc.) as part of the specifications of a communication standard, etc. In some aspects, the UE can receive configuration information via one or more of Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling (e.g., MAC Control Element (MAC CE)), etc. In some aspects, the configuration information may include indications of one or more configuration parameters (e.g., known to the UE) for the UE to select, explicit configuration information for the UE to configure the UE, etc.

[0058] In some aspects, the configuration information may instruct the UE to estimate and correct phase errors of multiple communications received via a single antenna panel, at least in part, based on the PT-RS of a single communication (e.g., spatially multiplexed communication). In other aspects, the configuration information may instruct the UE to send an indication of the association between TCI status identifiers and the UE's antenna panel. For example, the configuration information may instruct the UE to send a set of TCI status identifiers (via a report based on CRI or Synchronization Signal Block (SSB) identifiers, such as CRI-L1-RSRP) and an indication of which antenna panel the UE will use to receive communications sent by the TRP using each TCI status identifier in the set of TCI status identifiers.

[0059] As shown by reference numeral 410 in the accompanying drawings, the UE can be configured to communicate with a base station. In some aspects, the UE can be configured at least in part based on this configuration information. In some aspects, the UE can be configured to perform one or more of the operations described herein.

[0060] As shown by reference numeral 415 in the figure, the UE can instruct support for noise correction based on a single TRP PT-RS for each antenna panel. In other words, the UE can use the PT-RS received from the signal TRP and / or utilize a single communication among multiple communications to transmit an instruction that the UE can perform noise correction for multiple communications (e.g., from multiple TRPs) received via a single panel of the UE.

[0061] As shown by reference numeral 420 in the attached figure, the UE can transmit, and the base station can receive, an indication of a TCI status identifier (ID) associated with multiple SDM communications to be received by the UE's antenna panel. In some aspects, the UE can transmit an indication of a TCI status identifier associated with multiple SDM communications, wherein the TCI status identifier is associated with a single antenna panel of the UE.

[0062] In some aspects, the UE may send an indication of the TCI status identifier associated with a single antenna panel of the UE. For example, the UE may report a TCI status identifier (e.g., as part of a beam management procedure) along with an indication of the antenna panel associated with the TCI status identifier. In some aspects, the UE may send the TCI status identifier in a single communication with an indication of the antenna panel, wherein the indication of the antenna panel is associated with the TCI status identifier. In some aspects, the UE may send a single communication as part of beam management procedure communications, RSRP reports (e.g., CRI-L1-RSRP reports), SINR reports (e.g., CRI-L1-SINR reports), etc.

[0063] As shown by reference numeral 425, the base station can determine that the UE intends to receive multiple SDM communications associated with multiple TRPs via a single antenna panel of the UE. In some aspects, the base station can determine that the UE intends to receive multiple SDM communications associated with multiple TRPs via a single antenna panel of the UE, at least in part, based on an instruction received from the UE.

[0064] In some aspects, the base station may receive a set of indications of TCI status identifiers associated with one or more reference signals received by the UE via one or more TRPs, and determine the antenna panel of the UE associated with the TCI status identifier. The base station may determine, at least in part, that the UE will receive multiple SDM communications associated with multiple TRPs via a single antenna panel of the UE, based on the determination of the antenna panel of the UE associated with the TCI status identifier.

[0065] In some respects, the base station can determine that the UE needs to receive multiple additional SDM communications associated with multiple additional TRPs via an additional single antenna panel of the UE. The base station can configure a single additional TRP among the multiple additional TRPs to transmit PT-RS along with the additional communications in the multiple additional SDM communications for phase noise correction by the UE for use by the multiple additional SDM communications.

[0066] As shown by reference numeral 430 in the attached figure, a base station can configure a single TRP among multiple TRPs to transmit PT-RS to the UE. In some aspects, the base station can configure a single TRP to transmit SDM communication for different antenna panels of the UE.

[0067] As shown by reference numeral 435 in the attached figure, the UE can receive multiple SDM communications via a single antenna panel. In some aspects, the UE can receive multiple additional SDM communications via an additional single antenna panel.

[0068] As shown by reference numeral 440, the UE can perform phase noise correction using a PT-RS received via a single communication among multiple SDM communications. In some aspects, the UE can identify a single communication that includes a PT-RS for phase noise estimation and correction. In some aspects, more than one communication may include a PT-RS, and the UE can identify a single communication for phase noise estimation and correction, and the UE can ignore the PT-RS of the remaining communications that include a PT-RS. In some aspects, phase correction can be based at least partially on receiver phase noise. In some aspects, the UE can perform phase noise correction for each signal at least partially based on phase noise estimation (e.g., separately), wherein the phase noise estimation is based at least partially on a single communication among multiple SDM communications.

[0069] By configuring a single TRP out of multiple TRPs that need to transmit signals to a single panel of the UE to transmit signals along with PT-RS, the base station can save communication and / or network resources that would otherwise be used to carry PT-RS on each signal of multiple TRPs. By having the UE estimate and correct phase noise based at least in part on the PT-RS of a single communication of multiple signals, the UE can save computational resources that would otherwise be used to process PT-RS, estimate phase noise, and correct the phase noise of each signal individually.

[0070] As mentioned above, Figure 4 This is provided as an example only. Other examples can be found in the references. Figure 4 The descriptions are different.

[0071] Figure 5 This is a diagram illustrating example 500 associated with providing and / or using multi-link capability reporting, based on various aspects of this disclosure.

TRP group 530, TRP group 535, and TRP group 540 can be configured by one or more base stations to communicate with UE 120.

[0072] like Figure 5 As shown, UE 120 can communicate with TRP group 530 via first antenna board 505, with TRP group 535 via second antenna board 510, and with TRP group 540 via third antenna board 515. UE 120 can downsample the signals received at antenna panels 505, 510, and 515 from radio frequency (e.g., carrier frequency) to an intermediate frequency (IF) for each antenna panel. After downsampling the signal at each antenna panel, UE 120 can forward the signal to an IF-to-baseband (BB) converter 520. The IF-to-BB converter 520 can downsample the signal from the IF frequency range to the BB frequency range. UE 120 can forward the signal to one or more BB logic devices 525 to convert the signal into data, control information, etc.

[0073] The UE can receive communication with the PT-RS 545 from the TRP 530B. In some respects, the UE can use the communication with the PT-RS 545 to estimate and correct the phase error of the communication from the TRP 530A and / or the communication from the TRP 530C (e.g., at least in part based on the communication from the TRP 530A and / or the communication from the TRP 530C received via the same antenna panel of the UE).

[0074] The UE can receive communication with the PT-RS 550 from the TRP 535A. In some respects, the UE can use the communication with the PT-RS 550 to estimate and correct the phase error of the communication from the TRP 535B (e.g., based at least in part on the communication from the TRP 535A received via the same antenna panel of the UE).

[0075] The UE can receive communication with the PT-RS 555 from the TRP 540A. In some respects, the UE can use the communication with the PT-RS 555 to estimate and correct the phase error of the communication from the TRP 540B (e.g., based at least in part on the communication from the TRP 540A received via the same antenna panel of the UE).
