[0002] This patent application claims priority to Provisional Patent Application No. 63 / 090,559, filed October 12, 2020, entitled “TECHNIQUES FOR INDICATING A PANEL IDENTIFIER IN REPORTING RECEIVED BEAMS”, and U.S. Patent Application No. 17 / 498,563, filed October 11, 2021, entitled “TECHNIQUES FOR INDICATING A PANEL IDENTIFIER IN REPORTING RECEIVED BEAMSWHICH”, which are assigned to the assignee of this application and are expressly incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure generally relates to wireless communication systems, and more specifically, to techniques for receiving and reporting multiple beams using one or more antenna panels. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications content such as telephone, video, data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-s-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)).

[0005] Some wireless communication systems can support beamforming, where a first device (e.g., a base station or user equipment (UE)) can beamform a communication signal by selectively combining antenna elements in an antenna array to generate signal transmission or reception in the spatial direction of a second device. Both devices can perform a beam training process, allowing each device to select or otherwise determine the beams used to transmit or receive signals or communications from the other device. For example, in a typical beam training operation, the base station can transmit multiple transmit beams to the UE, and the UE can use each of multiple receive beams to receive each transmit beam. The UE can perform measurements using the multiple receive beams for a given transmit beam. The UE can send a beam report to the base station indicating measurements taken for each transmit beam received using each receive beam. The base station or UE can use this information to determine the beams used for subsequent communication. Summary of the Invention

[0006] The following is a simplified overview of one or more aspects to provide a basic understanding of them. This overview is not a comprehensive summary of all anticipated aspects, nor is it intended to identify key or important elements of all aspects, nor to depict the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed descriptions that follow.

[0007] In some aspects of this disclosure, a method, computer-readable medium, and apparatus are provided. In some aspects, the method includes: determining a configuration of one or more antenna panels for measuring a plurality of downlink beams from a base station; receiving the plurality of downlink beams from the base station at the one or more antenna panels; performing a measurement of a signal metric for each of the plurality of downlink beams received from the base station using each of the one or more antenna panels; and sending a beam report to the base station, the beam report including: a signal metric for each of the plurality of downlink beams, a signal metric for the downlink beam measurement, and an antenna panel identifier for one of the one or more antenna panels used to measure the downlink beams.

[0008] In another aspect, one method includes: sending a plurality of downlink beams to a user equipment (UE), and receiving a beam report from the UE, the beam report including: a signal metric for each of the plurality of downlink beams, a measurement of the downlink beam, and an antenna panel identifier at the UE for one of one or more antenna panels used to measure the downlink beams.

[0009] In another aspect, a method includes: receiving from a base station a configuration indicating a set of multiple antenna panels associated with a UE for performing measurements on multiple downlink beams; receiving multiple downlink beams from the base station, each of the multiple downlink beams being received concurrently by one or more antenna panels in the set of multiple antenna panels; performing one or more measurements on each of the received multiple downlink beams based on the configuration; and sending a beam report to the base station, the beam report including: one or more measurements of the downlink beams for each of the multiple downlink beams; and one or more antenna panel identifiers respectively indicating one or more antenna panels on which the downlink beams are received.

[0010] In another aspect, a method includes: sending a plurality of downlink beams to a UE, wherein the plurality of downlink beams correspond to downlink beams that can be received concurrently using one or more antenna panels; receiving a beam report from the UE, the beam report including: for each of the plurality of downlink beams, a signal metric for measuring the downlink beam; and an antenna panel identifier at the UE for measuring the downlink beam in one of the one or more antenna panels; and sending to the UE, based on the beam report, an indication of one or more parameters to be used for uplink transmissions from at least one of the one or more antenna panels.

[0011] To achieve the foregoing and related objectives, one or more aspects include the features fully described below and specifically pointed out in the claims. The following description and figures illustrate certain illustrative features of one or more aspects in detail. However, these features indicate only a few of the various ways in which the principles of each aspect can be employed, and this description is intended to include all such aspects and their equivalents.

[0022] The same reference numerals and names in the various figures indicate the same elements. Detailed Implementation

[0023] The detailed description below, illustrated with reference to the accompanying drawings, is intended as a description of various configurations and not as representing the only configuration in which the concepts described herein can be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0024] A user equipment (UE) may be equipped with multiple antenna panels or antenna arrays located at different locations within or on the UE, or facing different directions, to improve communication diversity. The UE may define one or more (or portions of) panels or arrays on or on the UE, or one or more virtual antenna panels, wherein each virtual antenna panel may include (or may be mapped to) one or more physical antenna panels or a portion of one or more physical antenna panels. In some examples, all antennas in an antenna panel may share the same timing advance (TA) or power control (PC). In the following description, both physical and virtual antenna panels may be collectively referred to as "antenna panel". Therefore, a reference to an antenna panel may refer to either a physical antenna panel or a virtual antenna panel. Each antenna panel (whether physical or virtual) may be associated with a corresponding antenna panel identifier. In some examples, a UE with multiple antenna panels may or may not be able to concurrently receive multiple downlink beams using each of the multiple antenna panels. For example, the UE may not be able to use one antenna panel to receive one downlink beam while simultaneously using another antenna panel to receive another downlink beam. This could be due to resource constraints at the UE, prohibitive radio conditions at one of the antenna panels, or other possible considerations.

[0025] These aspects generally relate to techniques for using multiple antenna panels to measure and report beam measurements. In some examples where the UE cannot concurrently receive multiple downlink beams, the UE may indicate that the same antenna panel will be used to receive any of the multiple received downlink beams. In other examples where the UE can use multiple antenna panels to communicate concurrently with the base station, the UE may determine the configuration of the multiple antenna panels for use when receiving and measuring downlink beams from the base station, and may subsequently send a beam report. The beam report may indicate one or more downlink beams, as well as indications of measurements or signal metrics associated with the one or more downlink beams. According to aspects of this disclosure, the UE may further send an antenna panel identifier associated with each measurement in the report. The base station may accordingly determine the number of antenna panels supported by the UE for concurrent communication based on the beam report indicating the antenna panel identifier(s). For example, the number of supported antenna panels may be one antenna panel or multiple antenna panels.

[0026] The base station can configure one or more parameters for communication with the UE based on the number of supported antenna panels (e.g., determined based on the number of antenna panel identifiers indicated in the beam report). For example, if the UE reports multiple antenna panel identifiers in the beam report, the base station can configure one or more parameters for each activated antenna panel for communication with the UE. For example, one or more parameters may include or indicate transmitted precoding matrix indicators (TPMIs), codebooks, etc., used for communication with the corresponding antenna panel. Therefore, the base station can configure uplink transmissions on multiple antenna panels of the UE to use one or more different communication parameters (e.g., one or more different TPMIs, codebooks, etc.).

[0027] Specific implementations of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some aspects of this disclosure, the UE providing the base station with information relating to the use of multiple antenna panels (such as one or more antenna panel identifiers) can allow the base station to transmit to at least a portion of the multiple panels of the UE. This can improve the communication throughput of the UE when communicating with the base station. Additionally, in some aspects, allowing the UE to indicate the availability or capability of multiple antenna panels via beam reporting can facilitate the selective activation of antenna panels (which may be optimal for use in a communication environment) to avoid the use of antenna panels that may be obstructed or interfered with.

[0028] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and methods. These apparatuses and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0029] For example, an element, or any part of an element, or any combination of elements, can be implemented as a "processing system" including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in a processing system can execute software. Whether referring to software, firmware, middleware, microcode, hardware description languages, or others, software should be interpreted broadly as representing instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc.

[0030] Therefore, in one or more example embodiments, the described functionality can be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality can be stored on a computer-readable medium or encoded as one or more instructions or code on a computer-readable medium. A computer-readable medium includes a computer storage medium. A storage medium can be any available medium accessible to a computer. By way of example and not limitation, such a computer-readable medium can include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of computer-readable media of the foregoing types, or any other medium that can be used to store computer-executable code in the form of computer-accessible instructions or data structures.

[0031] Figure 1 This is a diagram illustrating an example of a wireless communication system. The wireless communication system (also known as a wireless wide area network (WWAN)) includes a base station 102, a user interface unit (UE) 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macro cells include base stations. Small cells include femtocells, picocells, and microcells.

[0032] Base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). Base station 102 configured for 5G NR (which may be collectively referred to as Next Generation RAN (NG-RAN)) can interface with core network 190 via a second backhaul link 184. Among other functions, base station 102 can also perform one or more of the following functions: user data delivery, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of Non-Access Stratum (NAS) messages, NAS node selection, synchronization, Radio Access Network (RAN) sharing, Multimedia Broadcast Multicast Service (MBMS), subscriber and equipment tracking, RAN Information Management (RIM), paging, location, and delivery of alarm messages. Base stations 102 can communicate directly or indirectly with each other via a third backhaul link 134 (e.g., an X2 interface) (e.g., via EPC 160 or core network 190). The third backhaul link 134 can be wired or wireless.

[0033] Base station 102 can wirelessly communicate with UE 104. Each base station 102 can provide communication coverage for its respective geographical coverage area 110. Overlapping geographical coverage areas 110 may exist. For example, a small cell 102a may have a coverage area 110a that overlaps with the coverage areas 110 of one or more macro base stations 102. A network that includes both small cells and macro cells can be referred to as a heterogeneous network. The heterogeneous network may also include a Home Evolved Node B (eNB) (HeNB), which can provide services to a restricted group called a Closed Subscriber Group (CSG). The communication link 120 between base station 102 and UE 104 may include an uplink (UL) (also called a reverse link) transmission from UE 104 to base station 102 or a downlink (DL) (also called a forward link) transmission from base station 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity. These communication links may use one or more carriers. For each carrier allocated in carrier aggregation for transmission in each direction, totaling up to YxMHz (x component carriers), base station 102 / UE 104 may use a spectrum with a bandwidth of up to YMHz (e.g., 5, 10, 15, 20, 100, 400MHz, etc.). Carriers may or may not be adjacent to each other. Carrier allocation may be asymmetric relative to DL and UL (e.g., more or fewer carriers may be allocated to DL than to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the secondary component carrier may be referred to as the secondary cell (SCell).

[0034] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL WWAN spectrum. D2D communication link 158 can use one or more sidelink channels, such as Physical Sidelink Broadcast Channel (PSBCH), Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH). D2D communication can be achieved through various wireless D2D communication systems, such as FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0035] The wireless communication system may further include a Wi-Fi access point (AP) 150 communicating with a Wi-Fi station (STA) 152 via a communication link 154 in the unlicensed 5 GHz spectrum. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) before communication to determine whether the channel is available.

[0036] Small cell 102a can operate in licensed or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102a can employ NR and use the same 5 GHz unlicensed spectrum as Wi-FiAP 150. Small cell 102a employing NR in unlicensed spectrum can improve coverage of the access network or increase the capacity of the access network.

[0037] Base station 102 (whether it is a small cell 102A or a large cell (e.g., a macro base station)) may include or be referred to as an eNB, gNodeB (gNB), or another type of base station. Some base stations (such as gNB 180) may operate in the conventional sub-6 GHz spectrum, in millimeter wave (mmW) frequencies, or in near-mmW frequencies for communication with UE 104. When gNB 180 operates in mmW or near-mmW frequencies, gNB 180 may be referred to as an mmW base station. Extremely high frequency (EHF) is a part of the RF spectrum in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and wavelengths between 1 mm and 10 mm. Radio waves in this band may be referred to as millimeter waves. Near-mmW can extend down to a frequency of 3 GHz with a wavelength of 100 mm. Ultra-high frequency (SHF) bands extend between 3 GHz and 30 GHz and are also known as centimeter waves. Communication using mmW / near-mmW RF bands (e.g., 3 GHz-300 GHz) has extremely high path loss and short range. mmW base station 180 can utilize beamforming to generate beamforming signal 182 (also referred to as a “beam”) with UE 104 to compensate for extremely high path loss and short range. Base station 180 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, or antenna arrays) to facilitate beamforming. Although base station 102 and mmW base station 180 are shown separately, the aspects described herein with respect to base station 102 can be applied to and implemented by mmW base station 180.

[0038] Base station 180 can transmit beamforming signals to UE 104 in one or more transmit directions. UE 104 can receive beamforming signals from base station 180 in one or more receive directions. UE 104 can also transmit beamforming signals to base station 180 in one or more transmit directions. Base station 180 can receive beamforming signals from UE 104 in one or more receive directions. Base station 180 / UE 104 can perform beam training to determine the optimal receive and transmit directions for each of base station 180 / UE 104. The transmit and receive directions of base station 180 can be the same or different. The transmit and receive directions of UE 104 can be the same or different.

[0039] EPC 160 may include Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and Packet Data Network (PDN) Gateway 172. MME 162 can communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, or other IP services. BM-SC 170 can provide functions for MBMS user service provisioning and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS gateway 168 can distribute MBMS services to base stations 102 within broadcast-specific service multicast-broadcast-single-frequency (MBSFN) areas, and is responsible for session management (start / stop) and collecting billing information related to eMBMS.

[0040] Core network 190 may include Access and Mobility Management Function (AMF) 192, other AMFs 193, Session Management Function (SMF) 194, and User Plane Function (UPF) 195. AMF 192 can communicate with Unified Data Management (UDM) 196. AMF 192 is the control node that handles signaling between UE 104 and core network 190. Typically, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are transmitted via UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 connects to IP service 197. IP service 197 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, or other IP services.

[0041] Base stations may include or be referred to as gNB, B-node, eNB, access point, base transceiver station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), transmit / receive point (TRP), or any other suitable term. Base station 102 provides UE 104 with access to EPC 160 or core network 190. Examples of UEs 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional devices. Some of UEs 104 may be referred to as IoT devices (e.g., parking timers, air pumps, ovens, vehicles, heart monitors, and other examples). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, mobile phone, user agent, mobile client, client, or any other suitable term.

[0042] Refer again Figure 1In some aspects, UE 104 may include a communication component 198 configured to determine an antenna panel configuration of one or more antenna panels of UE 104 for communicating with base station 102 to at least receive, measure, or report downlink beams received from base station 102. In some aspects, base station 102 may include a configuration component 199 configured to receive beam reports from UE 104 indicating one or more antenna panel identifiers for communicating with base station 102. Although the following description may be based on 5G NR and related features, the concepts described herein are applicable to other domains or wireless communication technologies such as LTE, LTE-A, CDMA, Global System for Mobile Communications (GSM), or future communication standards or technologies.

[0043] Figure 2A Figure 200 is an example of the first subframe within the 5G / NR frame structure. Figure 2B Figure 230 illustrates an example of a DL channel within a 5G / NR subframe. Figure 2C Figure 250 shows an example of the second subframe within the 5G / NR frame structure. Figure 2D Figure 280 illustrates an example of a UL channel within a 5G / NR subframe. The 5G / NR frame structure can be Frequency Division Duplex (FDD), where, for a given set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to either DL or UL, or it can be Time Division Duplex (TDD), where, for a given set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to both DL and UL. Figure 2A , Figure 2C In the provided examples, it is assumed that the 5G / NR frame structure is TDD, where subframe 4 is configured with slot format 28 (primarily DL), where D is DL, U is UL, and X is flexible between DL and UL, and subframe 3 is configured with slot format 34 (primarily UL). Although subframes 3 and 4 are shown as having slot formats 34 and 28, respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are all DL and UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The UE is configured with a slot format via the received Slot Format Indicator (SFI) (dynamically via DL Control Information (DCI), or semi-statically / statically via Radio Resource Control (RRC) signaling). Note that the description given herein also applies to the TDD 5G / NR frame structure.

[0044] Other wireless communication technologies may have different frame structures or different channels. A frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include micro-time slots, which may include 7, 4, or 2 symbols. Depending on the time slot configuration, each time slot may include 7 or 14 symbols. For time slot configuration 0, each time slot may include 14 symbols, and for time slot configuration 1, each time slot may include 7 symbols. Symbols on the DL can be Cyclic Prefix (CP) OFDM (CP-OFDM) symbols. Symbols on the UL can be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the time slot configuration and parameter design. For slot configuration 0, different parameter sets μ0 to 5 allow 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different parameter sets 0 to 2 allow 2, 4, and 8 slots per subframe, respectively. Therefore, for slot configuration 0 and parameter set μ, there are 14 symbols / slots and 2... μ Each time slot / subframe. Subcarrier spacing and symbol length / duration are functions of a parameter set. Subcarrier spacing can be equal to 2. μ *15kHz, where μ is the parameter set from 0 to 5. Therefore, parameter set μ = 0 has a subcarrier spacing of 15kHz, and parameter set μ = 5 has a subcarrier spacing of 480kHz. The symbol length / duration is inversely proportional to the subcarrier spacing. Figures 2A-2D Examples are provided for slot configuration 0 with 14 symbols per slot and parameter set μ=0 with 1 slot per subframe. The subcarrier spacing is 15 kHz and the symbol duration is approximately 66.7 μs.

[0045] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) that extends 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0046] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. RSs may include demodulation RS (DM-RS) (indicated as Rx for a specific configuration, where 100x is the port number, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. RSs may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0047] Figure 2B The diagram illustrates examples of various DL channels within a subframe of a frame. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs), each CCE comprising nine RE Groups (REGs), each REG comprising four consecutive REs in an OFDM symbol. The Primary Synchronization Signal (PSS) can be located within symbol 2 of a specific subframe of the frame. The UE uses the PSS to determine subframe / symbol timing and the Physical Layer Identifier. The Secondary Synchronization Signal (SSS) can be located within symbol 4 of a specific subframe of the frame. The UE uses the SSS to determine the Physical Layer Cell Identifier Group Number and the radio frame timing. Based on the Physical Layer Identifier and Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DM-RS. The Physical Broadcast Channel (PBCH), carrying the Primary Information Block (MIB), can logically group with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block. The MIB provides the number of RBs in the system bandwidth and the System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information (e.g., System Information Block (SIB)) that is not transmitted via the PBCH, and paging messages.

[0048] like Figure 2C As illustrated, some REs in the diagram carry DM-RS for channel estimation at the base station (indicated as R for a specific configuration, but other DM-RS configurations are possible). The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be transmitted in the first or second symbol of the PUSCH. Depending on whether a short or long PUCCH is transmitted, and depending on the specific PUCCH format used, the PUCCH DM-RS can be transmitted in different configurations. Although not shown, the UE can transmit a Sounding Reference Signal (SRS). The base station can use the SRS for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0049] Figure 2D Examples of various UL channels within a subframe of a frame are shown. The PUCCH can be positioned as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat / request (HARQ) confirm (ACK) / negative ACK (NACK) feedback. The PUCCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), or UCI.

[0050] Figure 3 This is a block diagram of an example base station 310 and an example UE 350. In the DL, IP packets from EPC 160 can be provided to the controller / processor 375. The controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Serving Data Adaptation Protocol (SDAP) layer, the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer. The controller / processor 375 provides: RRC layer functionality associated with broadcasting system information (such as MIB, SIB), RRC connection control (such as RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with upper-layer packet data unit (PDU) transmission, error correction via automatic repeat / request (ARQ), concatenation, segmentation, and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority ordering.

[0051] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functions associated with various signal processing functions. Layer 1, including the physical (PHY) layer, may include error detection on the transport channel, forward error correction (FEC) encoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes such as binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM). The encoded and modulated symbols can then be segmented into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (such as a pilot) in the time or frequency domain, and then combined using inverse fast Fourier transform (IFFT) to generate a physical channel carrying a stream of time-domain OFDM symbols. The OFDM streams are spatially precoded to generate multiple spatial streams. The channel estimate from channel estimator 374 can be used to determine coding and modulation schemes and for spatial processing. The channel estimate can be derived from a reference signal transmitted by UE 350 or channel condition feedback. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0052] At UE 350, each receiver 354RX receives signals through its respective antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides this information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functions associated with various signal processing functions. The RX processor 356 can perform spatial processing on this information to recover any spatial streams destined for UE 350. If multiple spatial streams are destined for UE 350, the RX processor 356 can combine them into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier are recovered and demodulated by determining the most probable signal constellation point transmitted by base station 310, along with a reference signal. These soft decisions can be based on a channel estimate calculated by channel estimator 358. The soft decision is then decoded and deinterleaved to recover the data and control signals originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0053] The controller / processor 359 may be associated with a memory 360 that stores program code and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using ACK or NACK protocols to support HARQ operation.

[0054] Similar to the functionality described in conjunction with DL transmissions performed by base station 310, controller / processor 359 provides: RRC layer functionality associated with system information (e.g., MIB, SIB) capture, RRC connectivity, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with upper-layer PDU transmission, error correction via ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs to TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority processing, and logical channel priority ordering.

[0055] The TX processor 368 can use the channel estimate derived by the channel estimator 358 from the reference signal transmitted by the base station 310 or from feedback to select an appropriate coding and modulation scheme, and to facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0056] UL transmissions are processed at base station 310 in a manner similar to that described for the receiver function incorporated at UE 350. Each receiver 318RX receives signals via its respective antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides that information to RX processor 370.

[0057] The controller / processor 375 may be associated with a memory 376 that stores program code and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover IP packets from the UE 350. IP packets from the controller / processor 375 can be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK or NACK protocols to support HARQ operation.

[0058] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be combined Figure 1 The communication component 198 is configured to perform various aspects.

[0059] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be combined Figure 1 Configuration component 199 is configured to perform various aspects.

[0060] In some wireless communication technologies (such as 5G NR), a UE can be configured to receive, measure, and report downlink beams from a base station, which can be performed as part of beam training, as described. In 5G NR, for example, a UE can be configured to report the reception or measurement of multiple received downlink beams in a group-based beam reporting; however, there is currently no mechanism to report the associated antenna panel identifier at the antenna panel on which the UE receives or measures downlink beams. Supporting concurrent reception of uplink transmissions based on different downlink beams, and allowing the UE to report antenna panel identifiers for multiple antenna panels used to receive and measure multiple downlink beams, could enable the base station to determine support for multiple antenna panels at the UE 104 or the configuration for uplink communication for the UE 104 based on multiple antenna panels. For example, if multiple downlink beams simultaneously receive uplink transmissions from the same UE beam on the same antenna panel, a single TPMI or codebook-based PUSCH may be required. If multiple downlink beams simultaneously receive uplink transmissions from two UE beams on two antenna panels, there may be two TPMIs corresponding to the two UE antenna panels. In this regard, it may be beneficial for the UE to report the antenna panel identifier of each reported downlink beam in its group-based beam report, so that the base station can know whether there are multiple antenna panels, a single antenna panel, or the antenna port number of each antenna panel at the UE. The base station can use this information to determine the number of TPMIs and can accordingly configure the SRS port number in the SRS resource to determine the corresponding TPMI.

[0061] Figure 4 This is a flowchart illustrating an example of a method 400 for determining the configuration of one or more antenna panels for receiving downlink beams, according to some aspects of this disclosure. Method 400 may be performed by a UE (such as UE 104, wireless communication device 800, or wireless communication device 900). In some examples, method 400 may be performed by a portion of UE 104, wireless communication device 800, or wireless communication device 900 (such as including memory 360, memory 808, TX processor 368, RX processor 356, controller / processor 359, processor 806, or other components described herein).

[0062] Optionally, in block 402, the UE determines the configuration of one or more antenna panels to be used for measuring multiple downlink beams. In some implementations, panel configuration component 912, for example, in conjunction with communication component 198 (which may include TX processor 368, RX processor 356, controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910, or one or more other components described herein, or operating in combination with these components), may determine the configuration of one or more antenna panels to be used for measuring multiple downlink beams from a base station. In some examples, UE 104 may include multiple antenna panels, each of which may be a physical antenna panel or other antenna array located around UE 104, a virtual antenna panel comprising one or more physical antenna panels or a portion of one or more physical antenna panels, etc. Additionally, each antenna panel may have an associated antenna panel identifier. In some examples, the antenna panel identifier may include an SRS resource set identifier, an identifier associated with a reference signal resource or resource set, an identifier assigned to a target reference signal resource or resource set, an identifier configured in the spatial relationship information, etc. In any case, the antenna panel identifier can identify the antenna panel within UE 104.

[0063] In some examples, communication component 198 may determine the configuration of one or more antenna panels based on various considerations, such as the environment detected at UE 104, indications received from base station 102, etc. For example, communication component 198 may determine to use one or more antenna panels from a plurality of antenna panels based on antenna obstruction detected at UE 104 (such as obstruction of one or more of a physical antenna panel or array by a hand or other object). In another example, as further described herein, communication component 198 may determine the configuration of one or more antenna panels based on parameters received from base station 102. In any case, for example, the configuration of one or more antenna panels may correspond to multiple antenna panels(s) that can be used to concurrently receive multiple downlink beams from base station 102. In one example, as further described herein, communication component 198 may receive this configuration from base station 102.

[0064] In method 400, at block 404, UE 104 may receive multiple downlink beams from a base station at one or more antenna panels. In one aspect, communication component 198, for example in combination with one or more of the following components: TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910, or other components, may receive multiple downlink beams from a base station (e.g., base station 102) at one or more antenna panels. For example, UE 104 may use each of the one or more antenna panels to concurrently receive multiple downlink beams at least in overlapping time-domain resources (or, for example, in overlapping frequency resources).

[0065] In method 400, at block 406, UE 104 may perform a measurement of the signal metric for each of the multiple downlink beams received from the base station using each of the one or more antenna panels, based on a configuration of one or more antenna panels to be used for measuring the multiple downlink beams from the base station. In one aspect, beam measurement component 914, for example in conjunction with one or more of communication component 198, TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910, or other components, may perform a measurement of the signal metric for each of the multiple downlink beams received from the base station using each of the one or more antenna panels, based on a configuration of one or more antenna panels to be used for measuring the multiple downlink beams from the base station. In one example, this configuration may include a configuration determined or otherwise received at block 402. For example, beam measurement component 914 can measure signal metrics as the received signal strength or quality at one of one or more antenna panels (e.g., Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), Signal-to-Noise Ratio (SNR), Signal-to-Interference and Noise Ratio (SINR), etc.). Where multiple antenna panels are configured at UE 104, beam measurement component 914 can concurrently measure signal metrics of multiple downlink beams at each of the multiple antenna panels.

[0066] In method 400, at block 408, UE 104 may send a beam report to a base station, the beam report including: a signal metric for each of a plurality of downlink beams, a measurement of the downlink beam, and an antenna panel identifier for one of one or more antenna panels used to measure the downlink beam. In some aspects, beam reporting component 916, for example in conjunction with one or more of communication component 198, TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910 or other components, may send a beam report to a base station (e.g., base station 102), the beam report including: a signal metric for each of a plurality of downlink beams, a measurement of the downlink beam, and an antenna panel identifier for one of one or more antenna panels used to measure the downlink beam. For example, beam reporting component 916 can generate a group-based beam report indicating multiple downlink beam measurements. Beam reporting component 916 can include in the beam report an indication of antenna panel identifiers for the antenna panels used to measure each downlink beam. The indication of multiple antenna panel identifiers in the beam report allows base station 102 to determine that UE 104 can communicate concurrently using multiple antenna panels, and base station 102 can accordingly configure uplink communication for UE 104, as further described herein, to use multiple antenna panels and corresponding beams associated with the measured downlink beams.

[0067] For example, in group-based beam reporting, UE 104 can report panel identifiers associated with each of a plurality of downlink (DL) beams or reference signals (RS) that can be received simultaneously. Specifically, UE 104 can report at least one UE panel identifier and a corresponding measurement metric for each DL RS in the reported set of DL RSs that can be received simultaneously. In a specific example, for CSI-RS#1 from TRP1, UE 104 reports panel #1 with RSRP#1 and panel #2 with RSRP#2, while for CSI-RS#2 from TRP2, UE 104 reports panel #3 with RSRP#3 and panel #4 with RSRP#4. Any two UE panels, one from (panel #1, panel #2) and the other from (panel #3, panel #4), can receive CSI-RS#1 and #2 simultaneously. In DL Simultaneous Reception (Rx), this provides base station 102 with multiple options on UE RX beam sets for the same DL RS set, allowing base station 102 to quickly switch to another set if one UE RX beam set fails, for example, due to congestion. In UL Simultaneous Tx, in some examples, the reported panel ID and antenna port number per panel ID can help base station 102 identify the number of TPMIs and SRS port numbers in the SRS resources to determine the corresponding TPMI for the Tx beam used by UE 104.

[0068] Additionally, in some examples, the beam reporting component 916 may report additional information and at least one UE panel identifier and a corresponding measurement metric for each DLRS in the reported DLRS set. In some examples, for simultaneous Rx on (multiple) UE panels, the measurement metric for each panel ID may include L1-RSRP, L1-SINR, L1-RSRQ, etc., for each panel identifier, as described. For simultaneous Tx on (multiple) UE panels, for example, additional reporting information may include the available power margin for each panel identifier, which may include the maximum permissible UL Tx power of the panel, or the required ULTx power of the panel, which may be determined by the panel's power control. In another example, for simultaneous Tx on (multiple) UE panels, additional reporting information may include power backoff for each panel identifier, which may include the maximum UL Tx power of the panel determined by UE capabilities, or the maximum permissible UL Tx power of the panel, which may be due to maximum permissible exposure (MPE) limitations. In another example, for simultaneous Tx on (multiple) UE panels, additional reporting information may include an estimated maximum UL RSRP for each panel identifier, which may include the maximum permissible UL Tx power for that panel, or the path loss for that panel, where the path loss can be measured in DL. Base station 102 may also use this additional information when scheduling uplink transmissions for UE 104, selecting the beam to use, indicating the transmit power to use, etc.

[0069] Figure 5 This is a flowchart illustrating an example of a method 500 for determining the configuration of one or more antenna panels for receiving downlink beams or for uplink transmission, according to some aspects of this disclosure. Method 500 may be performed by a UE (such as UE 104, wireless communication device 800, or wireless communication device 900). In some examples, method 500 may be performed by UE 104, wireless communication device 800, or a portion of wireless communication device 900, such as by memory 360, memory 808, TX processor 368, RX processor 356, or controller / processor 359, processor 806, or other components. Method 500 may be included in the above... Figure 4 The boxes 402, 404, 406 and 408 described in method 400 may include one or more additional optional boxes as described below.

[0070] In method 500, optionally, at block 502, UE 104 may receive an indication of one or more parameters for uplink transmission from at least one antenna panel of one or more antenna panels based on a downlink beam. In some aspects, communication component 198, for example in conjunction with one or more of the following components: TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910, or other components, may receive an indication of one or more parameters for uplink transmission from at least one antenna panel of one or more antenna panels based on a downlink beam. For example, the beam report may include, in conjunction with, the parameters described above. Figure 4 Method 400 describes a beam report transmitted at block 406, which may indicate multiple downlink beams concurrently measured by UE 104 using one or more antenna panels, and antenna panel identifiers of one or more antenna panels. As described, base station 102 may use this information to determine one or more parameters for uplink transmission, such as one or more TPMIs or codebooks for each of the one or more antenna panels, and may (e.g., in uplink resource granting) transmit one or more parameters for uplink transmission.

[0071] In method 500, optionally at block 504, UE 104 may transmit uplink transmissions from at least one antenna panel of one or more antenna panels based on one or more parameters. In some aspects, communication component 198, for example in conjunction with one or more of TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910 or other components, may transmit uplink transmissions from at least one antenna panel of one or more antenna panels based on one or more parameters. For example, communication component 198 may use one or more antenna panels (e.g., multiple different antenna panels) and use TPMI, codebooks, etc., indicated for one or more antenna panels, to transmit uplink transmissions simultaneously or otherwise in overlapping time periods.

[0072] In method 500, optionally at block 506, UE 104 may receive from the base station an indication regarding whether the same or different antenna panels are preferably used to receive multiple downlink beams. In some aspects, communication component 198, for example in conjunction with one or more of the following components: TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910, or other components, may receive from the base station (e.g., base station 102) an indication regarding whether the same or different antenna panels are preferably used to receive multiple downlink beams (e.g., to receive multiple downlink reference signals transmitted using multiple downlink beams). In some examples, panel configuration component 912 may determine the configuration of one or more antenna panels (e.g., as in...) based on this indication. Figure 4 Method 400 (described in block 402) or measurements can be performed based on that instruction (as in... Figure 4 (As described in block 406 of method 400). For example, in some scenarios, using the same antenna panel identifier (e.g., receiving downlink beams and reporting using one or more antenna panels based on signal antenna panel identifiers) may be preferred for reliability or power saving purposes, while using different antenna panel identifiers (e.g., receiving downlink beams and reporting using multiple antenna panels based on multiple antenna panel identifiers) may be preferred for increased throughput.

[0073] In method 500, optionally at block 508, UE 104 may receive from the base station an indication of signal metrics for reporting measurements from antenna panels supporting downlink processing, uplink processing, or both downlink and uplink processing. In some aspects, communication component 198, for example in conjunction with one or more of the following components: TX processor 368, RX processor 356, or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910, or other components, may receive from the base station (e.g., base station 102) an indication of signal metrics for reporting measurements from antenna panels supporting downlink processing, uplink processing, or both downlink and uplink processing. In some examples, panel configuration component 912 may determine the configuration of one or more antenna panels (e.g., in...) based on this indication. Figure 4 Method 400 (described in block 402) or measurements can be performed based on that instruction (as in... Figure 4(As described in block 406 of method 400). For example, panel configuration component 912 may use one or more antenna panels that can simultaneously receive multiple downlink beams and conform to the indication (e.g., one or more antenna panels that support downlink processing, uplink processing, or both downlink and uplink processing, depending on the indication) to determine or perform measurements, and may configure one or more antenna ports for receiving, measuring, and reporting simultaneously received downlink beams to the base station. In some examples, a set of panel identifiers where each panel identifier supports both DL and UL can be used for both Rx and Tx simultaneously, because some panel identifiers may be DL only.

[0074] In method 500, optionally at block 510, UE 104 can receive from the base station an indication of whether measuring downlink beams from at least a portion of one or more antenna panels is permitted or prohibited. In some aspects, communication component 198, for example in conjunction with one or more of the following components: TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910, or other components, can receive from the base station (e.g., base station 102) an indication of whether measuring downlink beams from at least a portion of one or more antenna panels is permitted or prohibited. In some examples, panel configuration component 912 can determine the configuration of one or more antenna panels (e.g., in...) based on this indication. Figure 4 Method 400 (described in block 402) or measurements can be performed based on that instruction (as in... Figure 4 (As described in block 406 of method 400). For example, when some panel identifiers are also used for UL transmissions, they may have MPE or inter-cell interference issues, and the indication can designate such antenna panel identifiers as prohibited. In some examples, panel configuration component 912 can use one or more antenna panels that can simultaneously receive multiple downlink beams and conform to the indication (e.g., to include one or more antenna panels indicated as permitted or not indicated as prohibited) to determine or perform measurements.

[0075] In method 500, optionally at block 512, UE 104 may receive from a base station an indication for reporting signal metrics measured from an antenna panel having a minimum, maximum, or equal number of antenna ports. In some aspects, communication component 198, for example in conjunction with one or more of TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 908, transmitting component 910, or other components, may receive from a base station (e.g., base station 102) an indication for reporting signal metrics measured from an antenna panel having a minimum, maximum, or equal number of antenna ports. In some examples, panel configuration component 912 may determine the configuration of one or more antenna panels (e.g., in...) based on this indication. Figure 4 Method 400 (described in block 402) or measurements can be performed based on that instruction (as in... Figure 4 (As described in block 406 of method 400). For example, this may depend on the base station 102's preferences for reliability, throughput, power savings, simplified processing, etc., as stated above. In some examples, panel configuration component 912 may use one or more antenna panels that can simultaneously receive multiple downlink beams and conform to the indication (e.g., antenna panels with no more than a maximum number of antenna ports, at least a minimum number of antenna ports, or an equal number of antenna ports) to determine or perform measurements.

[0076] In some examples, the communication component 198 may receive one or more of the above indications from the base station 102 in the form of Radio Resource Control (RRC) signaling, Medium Access Control (MAC) control element (CE), or Downlink Control Information (DCI) associated with a downlink reference signal transmitted using a downlink beam.

[0077] Figure 6 This is a flowchart illustrating an example of a method 600 for receiving a beam report indicating one or more antenna panel identifiers for receiving one or more antenna panels for receiving a downlink beam, according to some aspects of this disclosure. Method 600 may be performed by a base station (such as base station 102, wireless communication device 800, or wireless communication device 1000). In some examples, method 600 may be performed by base station 102, wireless communication device 800, or a portion of wireless communication device 1000 (such as including memory 360, memory 808, TX processor 368, RX processor 356, controller / processor 359, processor 806, or other components described herein).

[0078] In block 602, the base station may transmit multiple downlink beams to the UE. In some implementations, beam generation component 1012 may generate and transmit multiple downlink beams to the UE (e.g., UE 104), for example, in conjunction with configuration component 199 (which may include TX processor 368, RX processor 356, controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 1008, transmitting component 1010, or one or more other components described herein). In some examples, beam generation component 1012 may generate and transmit multiple downlink beams, which may include transmitting multiple DLRS using multiple downlink beams to allow UE 104 to measure and report signal metrics of the downlink beams. Beam generation component 1012 may generate and transmit multiple downlink beams to be received by UE 104 based on multiple received beams (e.g., as part of beam training). In this regard, in the example, beam generation component 1012 can send multiple downlink beams to be received and measured before sending other communications (e.g., downlink data communications) to UE 104.

[0079] In block 604, the base station can receive a beam report from the UE, which includes: a signal metric for each of a plurality of downlink beams, a measurement of the downlink beam, and an antenna panel identifier at the UE for one of one or more antenna panels used to measure the downlink beam. In some implementations, beam report processing component 1014, for example, in conjunction with configuration component 199 (which may include one or more of the following components: TX processor 368, RX processor 356, controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio unit 804, processor 806, memory 808, receiving component 1008, transmitting component 1010, or other components described herein, or operating in conjunction with these), can receive a beam report from the UE (e.g., UE 104), which includes: a signal metric for each of a plurality of downlink beams, a measurement of the downlink beam, and an antenna panel identifier at the UE for one of one or more antenna panels used to measure the downlink beam. As described, for example, UE 104 can use one or more antenna panels to measure the downlink beam from base station 102 and can report the beam measurement and the antenna panel identifier of the antenna panel used to measure the downlink beam. Using this information, for example, base station 102 can determine uplink communication parameters for UE 104 to use one or more antenna panels in uplink transmission.

[0080] As described, for example, beam reporting may include additional information and at least one UE panel identifier for each DL RS in the reported DL RS set and a corresponding measurement metric for each panel identifier. In some examples, for simultaneous or otherwise time-based overlapping reception on (multiple) UE panels, the measurement metric for each panel ID may include L1-RSRP, L1-SINR, L1-RSRQ, etc., for each panel identifier, as described. For simultaneous or otherwise time-based overlapping transmission on UE panels, for example, additional reporting information may include available power margin for each panel identifier, which may include the maximum allowed UL Tx power of the panel, power backoff for each panel identifier, estimated maximum UL RSRP for each panel identifier, etc., and configuration component 199 may also use this additional information when scheduling uplink transmissions for UE 104, selecting the beam to use, indicating the transmit power to use, etc.

[0081] At block 606, base station 102 may send to the UE, based on a beam report, an indication of one or more parameters to be used for uplink transmission from at least one of one or more antenna panels. In some aspects, configuration component 199, for example in conjunction with one or more of the following components: TX processor 368, RX processor 356 or controller / processor 359, memory 360, receiver or transmitter 354, modem 802, radio 804, processor 806, memory 808, receiving component 1008, transmitting component 1010, or other components, may send to the UE (e.g., UE 104) an indication of one or more parameters to be used for uplink transmission from at least one of one or more antenna panels, based on a beam report, which may be based on a downlink beam. For example, the beam report may include a beam report received at block 604, which may indicate multiple downlink beams concurrently measured by UE 104 using one or more antenna panels, and antenna panel identifiers of one or more antenna panels. As described, beam report processing component 1014 can determine this information from the beam report, and configuration component 199 can use this information to determine one or more parameters for uplink transmission using one or more antenna panels, as described. The one or more parameters may include one or more TPMIs or codebooks for each of the one or more antenna panels for transmitting uplink communication. In some examples, an indicator may specify the parameters along with the antenna panel identifier of the antenna panel to be used.

[0089] Figure 8 A block diagram is shown illustrating an example of a wireless communication device 800 that indicates a panel identifier when reporting a received beam, according to some aspects of this disclosure. In some implementations, the wireless communication device 800 may be for use with a UE (such as a reference UE). Figure 1 Examples of devices used in one of the various UEs 104 described. In some implementations, the wireless communication device 800 may be provided at a base station (such as reference UE 104). Figure 1 Examples of devices used in the described base station 102. The wireless communication device 800 is capable of transmitting (or outputting for transmission) and receiving wireless communications (e.g., in the form of wireless packets). For example, the wireless communication device may be configured to transmit and receive packets in the form of Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) and Medium Access Control (MAC) PDUs.

[0090] The wireless communication device 800 may be or may include a chip, a system-on-a-chip (SoC), a chipset, a package, or a device, including one or more modems 802 (collectively referred to as "Modem 802"), which may include a WWAN modem (e.g., a 3GPP 4G LTE or 5G compatible modem). In some implementations, the wireless communication device 800 may also include one or more radios 804 (collectively referred to as "Radio 804"). In some implementations, the wireless communication device 800 may also include one or more processors, processing blocks, or processing elements 806 (collectively referred to as "Processor 806") and one or more memory blocks or elements 808 (collectively referred to as "Memory 808").

[0091] Modem 802 may include intelligent hardware blocks or devices, such as, for example, application-specific integrated circuits (ASICs). Modem 802 is typically configured to implement the PHY layer. For example, modem 802 is configured to modulate packets and output modulated packets to radio 804 for transmission over a wireless medium. Modem 802 is similarly configured to receive modulated packets received by radio 804 and demodulate the packets to provide demodulated packets. In addition to modulators and demodulators, modem 802 may also include digital signal processing (DSP) circuitry, automatic gain control (AGC), encoders, decoders, multiplexers, and demultiplexers. For example, when in transmit mode, data obtained from processor 806 is provided to an encoder that encodes the data to provide encoded bits. The encoded bits (using a selected MCS) are then mapped to points in a modulation constellation to provide modulated symbols. The modulated symbols can then be mapped to NSS spatial streams or NSSTS space-time streams. The modulated symbols in the corresponding spatial or space-time stream can then be multiplexed, transformed via an inverse fast Fourier transform (IFFT) block, and subsequently fed to the DSP circuitry for Tx windowing and filtering. The digital signal can then be fed to a digital-to-analog converter (DAC). The resulting analog signal can then be fed to an upconverter and finally to a radio 804. In beamforming implementations, the modulated symbols in the corresponding spatial stream are pre-encoded via a guide matrix before being fed to the IFFT block.

[0092] When in receive mode, the digital signal received from radio 804 is provided to the DSP circuitry, which is configured to acquire the received signal, for example, by detecting the presence of the signal and estimating the initial timing and frequency offset. The DSP circuitry is also configured to digitally condition the digital signal, for example, by using channel (narrowband) filtering, analog impairment conditioning (such as correcting I / Q imbalance), and applying digital gain to ultimately obtain a narrowband signal. The output of the DSP circuitry can then be fed to an AGC, which is configured to determine an appropriate gain using, for example, information extracted from the digital signal in one or more received training fields. The output of the DSP circuitry is also coupled to a demodulator, which is configured to extract modulated symbols from the signal and, for example, calculate the log-likelihood ratio (LLR) for each bit position of each subcarrier in each spatial stream. The demodulator is coupled to a decoder, which can be configured to process the LLR to provide decoded bits. The decoded bits from all spatial streams are then fed to a demultiplexer for demultiplexing. The demultiplexed bits can then be descrambled and provided to the MAC layer (processor 806) for processing, evaluation, or interpretation.

[0093] Radio 804 typically includes at least one radio frequency (RF) transmitter (or “transmitter chain”) and at least one RF receiver (or “receiver chain”), which can be combined into one or more transceivers. For example, the RF transmitter and receiver may include various DSP circuitry, each including at least one power amplifier (PA) and at least one low-noise amplifier (LNA). The RF transmitter and receiver may be coupled to one or more antennas accordingly. For example, in some implementations, wireless communication device 800 may include or be coupled to multiple transmit antennas (each with a corresponding transmit chain) and multiple receive antennas (each with a corresponding receive chain). Symbols output from modem 802 are provided to radio 804, which then transmits the symbols via the coupled antennas. Similarly, symbols received via the antennas are acquired by radio 804, which then provides the symbols to modem 802.

[0094] Processor 806 may include intelligent hardware blocks or devices designed to perform the functions described herein, such as, for example, processing cores, processing blocks, central processing units (CPUs), microprocessors, microcontrollers, digital signal processors (DSPs), application-specific integrated circuits (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), discrete gate or transistor logic, discrete hardware components, or any combination thereof. Processor 806 processes information received via radio 804 and modem 802, and processes information to be output via modem 802 and radio 804 for transmission over a wireless medium. For example, processor 806 may implement a control plane and MAC layer configured to perform various operations related to the generation and transmission of PDUs, frames, or packets. The MAC layer is configured to perform or facilitate frame encoding and decoding, spatial multiplexing, space-time block coding (STBC), beamforming, and OFDMA resource allocation, as well as other operations or techniques. In some implementations, processor 806 may typically control modem 802 to cause the modem to perform the various operations described above.

[0095] Memory 808 may include tangible storage media, such as random access memory (RAM) or read-only memory (ROM), or combinations thereof. Memory 808 may also store non-transitory processor or computer-executable software (SW) code containing instructions that, when executed by processor 806, cause the processor to perform various operations described herein for wireless communication, including the generation, transmission, reception, and interpretation of PDUs, frames, or packets. For example, the various functions of the components disclosed herein, or the various blocks or steps of the methods, operations, processes, or algorithms disclosed herein, may be implemented as one or more modules of one or more computer programs.
