Description

Technical Field

[0001] This disclosure generally relates to communication systems, and more specifically to MPE reporting in wireless communication systems. Background Technology

[0002] 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 enable communication with multiple users by sharing available system resources. 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, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0003] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the city, national, regional, and even global levels. An exemplary telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Evolution of Mobile Broadband (CEM) program issued by the 3rd Generation Partnership Project (3GPP) to meet new requirements related to latency, reliability, security, scalability (e.g., scalability for the Internet of Things (IoT),) and others. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. These improvements can also be applied to other multiple access technologies and telecommunications standards that adopt them. Summary of the Invention

[0004] The following is a simplified overview of one or more aspects to provide a basic understanding of these aspects. 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 describe 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 an introduction to the more detailed descriptions that follow.

[0005] In one aspect of this disclosure, a method, computer-readable medium, and apparatus are provided. The apparatus may be a user equipment (UE). In some aspects, the apparatus may transmit one or more uplink beams to a base station or receive one or more downlink beams from the base station, wherein at least one MPE event is detected for at least one of the one or more uplink beams or the one or more downlink beams. The apparatus may also detect at least one Maximum Allowable Exposure (MPE) event for at least one of the one or more uplink beams, one or more downlink beams, or one or more UE panels. Additionally, the apparatus may configure a Power Headroom Report (PHR) including at least one of an MPE value, at least one beam identifier (ID), or at least one panel ID when the MPE event is detected, the MPE value being associated with the MPE event, the at least one beam ID corresponding to the one or more uplink beams or the one or more downlink beams, and the at least one panel ID corresponding to the one or more UE panels. The apparatus may also transmit the PHR including at least one of the MPE value, the at least one beam ID, or the at least one panel ID to the base station.

[0006] In one aspect of this disclosure, a method, computer-readable medium, and apparatus are provided. The apparatus may be a base station. In some aspects, the apparatus may transmit one or more downlink beams to a user equipment (UE) or receive one or more uplink beams from a UE. The apparatus may also receive from the UE a power headroom report (PHR) including at least one of a maximum allowed exposure (MPE) value, at least one beam identifier (ID), or at least one panel ID, wherein the MPE value is associated with an MPE event, the at least one beam ID corresponds to the one or more uplink beams or the one or more downlink beams, and the at least one panel ID corresponds to one or more UE panels.

[0031] The specific embodiments described below with reference to the accompanying drawings are intended as descriptions of various configurations and are not intended to represent the only configuration in which the concepts described herein can be practiced. These specific embodiments include detailed descriptions intended to provide 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 detailed descriptions. In some cases, various well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0032] 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 specific embodiments and illustrated in the accompanying drawings by means of various frames, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0033] As an example, an element, any part of an element, or any combination of elements may 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 (SoC) processors, 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 may execute software. Software should be interpreted broadly as representing instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, application programs, software applications, software packages, routines, subroutines, objects, executable programs, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description languages, or otherwise.

[0034] 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 or encoded as one or more instructions or code on a computer-readable medium. A computer-readable medium includes a computer storage medium. The storage medium can be any available medium accessible to a computer. Exemplarily, and not limitingly, such a computer-readable medium can include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage devices, magnetic disk storage devices, 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.

[0035] Figure 1 This is a schematic diagram illustrating an example of a wireless communication system and access network 100. 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)). The 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.

[0036] Base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can be connected to EPC 160 interface via a first backhaul link 132 (e.g., S1 interface). Base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can be connected to core network 190 interface via a second backhaul link 184. Among other functions, base station 102 can perform one or more of the following functions: forwarding user data, 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), user and equipment tracking, RAN information management (RIM), paging, location, and delivery of warning messages. Base station 102 can communicate directly or indirectly with each other (e.g., via EPC 160 or core network 190) via third backhaul link 134 (e.g., X2 interface). First backhaul link 132, second backhaul link 184 and third backhaul link 134 can be wired or wireless.

[0037] Base station 102 can wirelessly communicate with UE 104. Each base station 102 can provide communication coverage for a corresponding geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, a small cell 102' may have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network including small cells and macro cells can be referred to as a heterogeneous network. The heterogeneous network may also include Home Evolution Node B (eNB) (HeNB) that can provide services to restricted groups referred to as Closed Subscriber Groups (CSGs). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also known as 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. The communication link may use one or more carriers. Base station 102 / UE 104 can use spectrum allocated to each carrier in a total carrier aggregation of up to Y x MHz (x component carriers) for transmission in each direction, with a bandwidth of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.). Carriers may be adjacent to each other or not. Carrier allocation may be asymmetrical for 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 auxiliary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the auxiliary component carriers may be referred to as secondary cells (SCells).

[0038] 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 sideline channels, such as the Physical Sideline Broadcast Channel (PSBCH), Physical Sideline Discovery Channel (PSDCH), Physical Sideline Shared Channel (PSSCH), and Physical Sideline Control Channel (PSCCH). D2D communication can be conducted through various wireless D2D communication systems, such as WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0039] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, 5 GHz unlicensed spectrum. When communicating in unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) before communication to determine whether the channel is available.

[0040] Small cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102' can employ NR and use the same unlicensed spectrum (e.g., 5 GHz, etc.) as the Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can improve the coverage and / or increase the capacity of the access network.

[0041] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating frequency bands are designated as frequency range names FR1 (410MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz). The frequencies between FR1 and FR2 are generally referred to as the intermediate frequency band (IF). Although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the "sub-6GHz" band in various documents and articles. Similar naming issues sometimes arise regarding FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although this differs from the extremely high frequency (EHF) band (30GHz-300GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU).

[0042] In light of the foregoing, unless otherwise specifically stated, it should be understood that, as used herein, the term "sub-6GHz" and the like can broadly refer to frequencies that are less than 6GHz, within FR1, or that may include intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that, as used herein, the term "millimeter wave" and the like can broadly refer to frequencies that may include intermediate frequency band frequencies, within FR2, or that may include EHF band frequencies.

[0043] Base station 102, whether a small cell 102' or a large cell (e.g., a macro base station), may include and / 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 to communicate with UE 104 at millimeter-wave and / or near-millimeter-wave frequencies. When gNB 180 operates at millimeter-wave or near-millimeter-wave frequencies, gNB 180 may be referred to as a millimeter-wave base station. Millimeter-wave base station 180 may utilize beamforming 182 with UE 104 to compensate for path loss and short range. Base station 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming.

[0044] Base station 180 may transmit beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamformed signals from base station 180 in one or more receive directions 182'. UE 104 may also transmit beamformed signals to base station 180 in one or more transmit directions. Base station 180 may receive beamformed signals from UE 104 in one or more receive directions. Base station 180 / UE 104 may perform beamforming 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 may be the same or different. The transmit and receive directions of UE 104 may be the same or different.

[0045] 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 forwarded 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, and / or other IP services. The BM-SC 170 provides functionality for MBMS user service provisioning and delivery. It 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 station 102 within a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and is responsible for session management (start / stop) and collecting billing information related to eMBMS.

[0046] The core network 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 may communicate with Unified Data Management (UDM) 196. AMF 192 is the control node that handles signaling between UE 104 and the core network 190. Typically, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are forwarded through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 connects to IP services 197. IP services 197 may include the Internet, intranets, IP Multimedia Subsystem (IMS), Packet Switched (PS) Streaming Service (PSS), and / or other IP services.

[0047] Base stations may include and / or be referred to as gNB, Node B, eNB, access point, base transceiver, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), Transmitter Receiver Point (TRP), or any other suitable term. Base station 102 provides UE 104 with access to EPC 160 or core network 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, electricity meters, oil pumps, large or small kitchen appliances, medical devices, implants, sensors / actuators, displays, or any other similar functional devices. Some UE 104s may be referred to as IoT devices (e.g., parking meters, oil pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, user station, mobile unit, user unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile user station, access terminal, mobile terminal, radio terminal, remote terminal, mobile phone, user agent, mobile client, client, or any other suitable term.

[0048] Refer again Figure 1In some aspects, UE 104 may include a determining component 198 configured to transmit one or more uplink beams to a base station or receive one or more downlink beams from the base station, wherein at least one MPE event is detected for at least one of the one or more uplink beams or the one or more downlink beams. The determining component 198 may also be configured to detect at least one Maximum Allowable Exposure (MPE) event for at least one of the one or more uplink beams, one or more downlink beams, or one or more UE panels. The determining component 198 may also be configured to configure a Power Headroom Report (PHR) upon detecting an MPE event, including at least one of an MPE value, at least one beam identifier (ID), or at least one panel ID, the MPE value being associated with the MPE event, the at least one beam ID corresponding to the one or more uplink beams or the one or more downlink beams, and the at least one panel ID corresponding to the one or more UE panels. The determining component 198 may also be configured to transmit the PHR to the base station, including at least one of the MPE value, the at least one beam ID, or the at least one panel ID.

[0049] Refer again Figure 1 In some aspects, base station 180 may include a determining component 199 configured to send one or more downlink beams to a user equipment (UE) or receive one or more uplink beams from a UE. The determining component 199 may also be configured to receive from the UE a power headroom report (PHR) including at least one of a maximum allowed exposure (MPE) value, at least one beam identifier (ID), or at least one panel ID, the MPE value being associated with an MPE event, the at least one beam ID corresponding to the one or more uplink beams or the one or more downlink beams, and the at least one panel ID corresponding to one or more UE panels.

[0050] Although the following description may focus on 5G NR, the concepts described herein are applicable to other similar areas such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0051] Figure 2A This is a schematic diagram 200 showing an example of the first subframe within a 5G NR frame structure. Figure 2B This is a schematic diagram 230 illustrating an example of a DL channel within a 5G NR subframe. Figure 2C This is a schematic diagram 250 showing an example of a second subframe within a 5G NR frame structure. Figure 2DThis is a schematic diagram 280 illustrating an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be either Frequency Division Duplex (FDD) or Time Division Duplex (TDD). In FDD, for a given set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to either DL or UL. In TDD, for a given set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to both DL and UL. Figure 2A , 2C In the provided example, it is assumed that the 5G NR frame structure is TDD, where subframe 4 is configured with slot format 28 (mostly DL), where D is DL, U is UL, and F is used flexibly between DL / UL, and subframe 3 is configured with slot format 1 (all UL). Although subframes 3 and 4 are shown with slot formats 1 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 slot format is configured for the UE via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-static / static configured via Radio Resource Control (RRC) signaling). Note that the following description also applies to 5G NR frame structures that are TDD.

[0052] Other wireless communication technologies may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 subframes (1 ms) of the same size. Each subframe may include one or more time slots. Subframes may also include micro-slots, which may contain 7, 4, or 2 symbols. Each time slot may contain 7 or 14 symbols, depending on the time slot configuration. For time slot configuration 0, each time slot may contain 14 symbols, and for time slot configuration 1, each time slot may contain 7 symbols. Symbols on the DL can be Cyclic Prefix (CP) Orthogonal Frequency Division Multiplexing (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 digital scheme. For slot configuration 0, different digital schemes μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For slot configuration 1, different digital schemes 0 to 2 allow 2, 4, and 8 slots per subframe, respectively. Therefore, for slot configuration 0 and digital scheme μ, there are 14 symbols / slots and 2... μ Each time slot / subframe. Subcarrier spacing and symbol length / duration are functions of the digital scheme. Subcarrier spacing can be equal to 2.μ *15kHz, where μ is the digital scheme from 0 to 4. Thus, the subcarrier spacing is 15kHz for digital scheme μ=0 and 240kHz for digital scheme μ=4. 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 a digital scheme μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within the frame set, one or more different bandwidth portions (BWPs) of frequency division multiplexing can exist (see [link to relevant documentation]). Figure 2B Each BWP can have a specific digital scheme.

[0053] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) extending for 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.

[0054] like Figure 2A As shown, some REs carry reference (pilot) signals (RS) for the UE. RSs may include demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are also 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).

[0055] Figure 2BExamples of various DL channels within a subframe of a frame are shown. The Physical Downlink Control Channel (PDCCH) carries the DCI in one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE Groups (REGs), each REG comprising 12 consecutive REs in the OFDM symbols of an RB. A PDCCH within a BWP may be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a common search space, a UE-specific search space) during PDCCH monitoring timing on the CORESET, where PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. The Primary Synchronization Signal (PSS) may be located within symbol 2 of a specific subframe of the frame. UE 104 uses the PSS to determine subframe / symbol timing and physical layer identification. The Secondary Synchronization Signal (SSS) may 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 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 Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the number of RBs and the System Frame Number (SFN) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted via the PBCH (such as System Information Block (SIB)), and paging messages.

[0056] like Figure 2C As shown, some REs carry DM-RS for channel estimation at the base station (indicated as R for a particular configuration, but other DM-RS configurations are also possible). The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). PUSCH DM-RS can be transmitted in the first one or two symbols before the PUSCH. PUCCH DM-RS can be transmitted in different configurations depending on whether a short or long PUCCH is transmitted and depending on the specific PUCCH format used. The UE can transmit a Sounding Reference Signal (SRS). SRS can be transmitted in the last symbol of a subframe. SRS can have a comb structure, and the UE can transmit SRS on one of these combs. The base station can use SRS for channel quality estimation to enable frequency-based scheduling on the UL.

[0057] Figure 2DExamples 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) acknowledgment (ACK) (HARQ-ACK) information (ACK / NACK (NACK)) feedback. The PUCCH carries data and can also be used to carry buffer status reports (BSR), power headroom reports (PHR), and / or UCI.

In the DL, IP packets from EPC 160 can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functions associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., 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 functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with forwarding of upper-layer packet data units (PDUs), error correction via 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 functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs to transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority processing, and logical channel priority ordering.

[0059] 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 and demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The encoded and modulated symbols can then be divided into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then combined using inverse fast Fourier transform (IFFT) to produce a physical channel carrying a stream of time-domain OFDM symbols. The OFDM streams are spatially precoded to produce 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 and / 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.

[0060] At UE 350, each receiver 354RX receives signals through its corresponding 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 the information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, they can be combined by the RX processor 356 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 consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols and reference signals on each subcarrier are recovered and demodulated by determining the most probable signal constellation point transmitted by base station 310. These soft decisions can be based on channel estimates calculated by channel estimator 358. The soft-decision decoding and deinterleaving are then performed to recover the original data and control signals 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 functions.

[0061] 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 and / or NACK protocols to support HARQ operation.

[0062] Similar to the functions described in the DL transmission combined with base station 310, controller / processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with forwarding of upper-layer PDUs, error correction via ARQ, splicing, segmentation, and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs on TB, demultiplexing of MAC SDUs from TB, scheduling information reporting, error correction via HARQ, priority processing, and logical channel priority ordering.

[0063] The channel estimate derived from the reference signal or feedback sent by the channel estimator 358 from the base station 310 can be used by the TX processor 368 to select an appropriate coding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via individual transmitters 354TX. Each transmitter 354TX can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0064] UL transmissions are processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318RX receives signals via its corresponding antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides that information to RX processor 370.

[0065] 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 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 and / or NACK protocols to support HARQ operation.

[0066] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform combination. Figure 1 198 in all aspects.

[0067] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform combination. Figure 1 199 in all aspects.

[0068] In wireless communication, Maximum Permissible Exposure (MPE) is a specified amount used to limit the maximum transmit power in the direct path of a human body. For example, if a human body is in the direct path of a transmit beam, this can trigger the detection of an MPE event. In some aspects, the UE can perform transmit (Tx) upper limit determination upon detecting an MPE event. Based on the MPE event, the amount of the Tx upper limit can vary depending on the distance between the transmitting device and the user or human body. For example, if the distance between the human body and the transmitting device (e.g., the UE) is close, the upper limit of Tx can be set at a certain amount (e.g., 8 dBm). Furthermore, if the distance between the human body and the transmitting device is greater, the upper limit of Tx can be set at a higher amount, such as 34 dBm.

[0069] For some detected MPE events, downlink transmission may be acceptable because the human body is far from the transmitting device (e.g., base station). However, for the same detected MPE events, uplink transmission may be unacceptable because the human body is closer to the transmitting device (e.g., UE). Therefore, uplink transmission corresponding to MPE events may require alternative uplink beams to ensure successful uplink transmission.

[0070] Figure 4A , 4B 4C and 4C are schematic diagrams 400, 420, and 450, respectively, illustrating example communication between the UE and the base station. Figure 4A As shown, schematic diagram 400 includes UE 402 transmitting and / or receiving one or more beams (e.g., beam 410) with base station 404. Figure 4A In this scenario, both uplink (UL) and downlink (DL) transmissions are acceptable because no MPE event is detected. For example... Figure 4B As shown, schematic diagram 420 includes UE 422 transmitting and / or receiving one or more beams (e.g., beam 430) with base station 424. Figure 4B In the scenario described, based on the MPE event detected due to the human body 440, downlink transmission may be acceptable, but uplink transmission may be unacceptable. For example... Figure 4CAs shown, schematic diagram 450 includes UE 452 transmitting and / or receiving one or more beams, such as beams 460 and 462, with base station 454. Figure 4C In the scenario described, downlink transmission is acceptable based on the MPE event detected due to human body 470, but direct uplink transmission may be unacceptable. Therefore, the uplink transmission can be modified to reflect from object 480 to avoid human body 470.

[0071] Various aspects of wireless communication can include a single-panel power headroom report (PHR) that can be sent from the UE to the base station. Some aspects of wireless communication include single-cell PHR reporting, which can include reporting MPE events. In the single-cell PHR report, 'R' can be a reserved bit and can be set to a value, such as 0. The power headroom (PH) field 'PH' can indicate the power headroom level. If MPE reporting parameters (e.g., mpe-Reporting) are configured, the 'P' bit can be set to 0 if the power backoff is less than a threshold (e.g., P_MPR_0). If the power backoff is greater than the threshold (e.g., P_MPR_0), the 'P' bit can be set to 1. If the 'P' bit is set to 0, the MPE value may not be reported. If the 'P' bit is set to 1, the MPE value may be reported.

[0072] Maximum transmit power (P) CMAX,f,c The field indicates the P used to calculate the previous PH field. CMAX,f,c In some aspects, if the MPE reporting parameter (mpe-Reporting) is not configured, then if the corresponding P... CMAX,f,c If a field has a different value when no power backoff is applied (e.g., due to power management), the 'P' bit can be set to a value of 1. Alternatively, if mpe-Reporting is configured and the 'P' field is set to 1, the MPE field can indicate the applied power backoff to meet the MPE specification. If mpe-Reporting is configured or if the P field is set to a value of 1, the MPE field can indicate the index of the corresponding measurement value for the Power Management Maximum Power Reduction (P-MPR) level in dB; otherwise, there are R bits. In some aspects of wireless communication, in multi-cell PHR reports, the 'Ci' field can be the serving cell index. Furthermore, the 'V' field can indicate whether the PH value is based on actual transmission (e.g., V=0) or a reference format (e.g., V=1). For virtual PHRs based on a reference format, Pcmax may not be reported. Therefore, if V is set to a value of 1, Pcmax may not be reported.

[0073] Figure 5A and 5BThese are schematic diagrams 500 and 510, respectively, illustrating example bitmaps for wireless communication. More specifically, Figure 5A and 5B A bitmap of multi-cell PHR reports is shown. (e.g.) Figure 5A and 5B As shown, there are multiple bitmap entries, and each entry can include a single cell. Each bit in the bitmap represents a cell index, enabling the creation of a PHR report for that cell. Figure 5A The schematic diagram 500 shows eight (8) entries, each corresponding to a serving cell. For example... Figure 5A As shown, bit C0 corresponds to the reserved bit 'R'. Figure 5B The schematic diagram 510 shows 32 cells, where each entry corresponds to a serving cell.

[0074] In some respects, when an MPE event occurs, the base station may require additional beam information from the UE during the reporting of beam-specific MPE events. Based on the above, providing beam-specific MPE reporting may be beneficial, where the power back-off value (i.e., MPE value) during the MPE event can be applied differently from beam-to-beam or from antenna panel-to-antenna panel. Including additional beam information for MPE events in the PHR may also be beneficial. Alternatively, a virtual PHR can report the PHR value but may not report other information. However, for beam-specific MPE events, even in virtual PHR reporting, the base station may require additional information related to the beam-specific MPE event. Therefore, including additional information related to beam-specific MPE events in the virtual PHR report may be beneficial.

[0075] Various aspects of this disclosure may provide beam-specific MPE reports. When reporting beam-specific MPE events, various aspects of this disclosure may also include additional beam information from the UE. For example, various aspects of this disclosure may include additional beam information for MPE events in the PHR. Various aspects of this disclosure may also include additional information related to beam-specific MPE events in the virtual PHR report.

[0076] In some instances, when the UE is configured for multi-panel operation, aspects of this disclosure can enhance single-cell PHR reporting by including additional beam IDs and / or panel IDs to indicate the reported beam-specific MPE value. For example, the beam ID can be included in a new octet along with other information such as Synchronization Block (SSB) ID, Channel State Information Reference Signal (CSI-RS) ID, Sound Reference Signal (SRS) ID, Uplink Spatial Relationship Information ID, or Transmission Configuration Indicator (TCI) Status ID. Additionally, the panel ID can optionally be configured to be reported along with the beam ID.

[0077] In some respects, a panel ID or beam ID can indicate the beam associated with a reported MPE event. An MPE value can be associated with a panel ID or beam ID such that the MPE value is specific to one or more beams among multiple panels at the UE. If the associated MPE value is acceptable, the panel ID or beam ID can correspond to a candidate panel or beam indication. Furthermore, if the MPE value is small, the panel or beam may be available for uplink transmission. Otherwise, if the MPE value is large, the panel ID or beam ID may correspond to a failed panel or beam indication. Therefore, if the MPE value is relatively large, the panel and / or beam may not be available for uplink transmission.

[0078] As described above, the beam ID and / or panel ID can be different because they refer to a specific beam or a specific panel on the UE. Therefore, aspects of this disclosure can report both the beam ID and the panel ID independently and differently. Furthermore, the 'C' bit in the PHR can be optionally configured to be reported when reporting the beam ID or the panel ID. For example, if C is set to a value of 1, the beam ID can be reported; otherwise, it can be left unreported. Additionally, 'C' can optionally be reported as C1 in the same octet as the PH value, or as C2 in another octet. For example, if C1 is set to a value of 1, the beam ID can be reported, or if C2 is set to a value of 1, the beam ID can be reported.

[0079] In some respects, a certain level of the UE (e.g., application level) can detect the presence of an MPE event. Once an MPE event is detected, it can be passed to a lower level for sending a PHR report. The UE can send a PHR report based on the MPE event and provide updated information for the downlink or uplink beam or UE panel. When the UE indicates a beam ID or UE panel ID, the base station can determine which beam or panel the MPE event corresponds to.

[0080] In some instances, the PHR bitmap may include a cell ID. If no additional cell ID is provided, this can refer to the primary cell ID. Furthermore, if the cell is a serving cell, a specific cell ID may exist. For example, the 'C' bit in the bitmap may refer to a specific serving cell ID. In some aspects, the primary cell may utilize a single-cell PHR report that does not include any cell ID or cell identifier. Therefore, if a specific serving cell ID does not exist, this may correspond to a single-cell PHR report for the primary cell.

[0081] Figure 6A , 6B 6C and 6C are schematic diagrams 600, 610, and 620, respectively, illustrating example bitmaps for wireless communication. More specifically, Figure 6A and6B A bitmap is shown for use in PHR reports. Figure 6A A single-entry PHR is displayed, so the UE can report the PH for a single panel. For example... Figure 6A As shown, the panel ID can optionally be configured to be reported along with the beam ID. Alternatively, the panel ID can correspond to a reserved bit in the bitmap. Figure 6A As shown, beam ID and panel ID can be reported independently and differently. Furthermore, the 'C' bit in the PHR can be optionally configured to be reported when reporting either the beam ID or the panel ID. For example, if C is set to a value of 1, the beam ID can be reported; otherwise, it can be omitted. Additionally, 'C' can optionally be reported as C1 or C2. For example, if C1 is set to a value of 1, the beam ID can be reported, or if C2 is set to a value of 1, the beam ID can be reported. If C1 or C2 is set to a value of 0, the beam ID can be omitted.

[0082] like Figure 6B and 6C As shown, schematics 610 and 620 correspond to multi-entry PHRs, so the UE can report PHs for multiple panels or multiple beams of a cell. Figure 6B and 6C This can be similar to a single-cell PHR report with multiple panels or multiple beams. For example... Figure 6B and 6C As shown, when the UE is configured for multi-panel operation, single-cell PHR reporting can be enhanced with a flexible number of entries indicating beam-specific PHR or MPE values ​​and beam IDs. For example, as Figure 6B As shown, when the X bit is set to a value of 0, this indicates that a PHR / MPE report is being sent for a beam / panel. Figure 6C As shown, when the X bit is set to a value of 1, this indicates that a second PHR / MPE is also reported for another beam / panel. Therefore, when the X bit is set to a value of 1, the UE can report two entries for the PHR report. The first entry for the PHR report can correspond to the first panel, and the second entry for the PHR report can correspond to the second panel, and the panel ID can indicate which panel is associated with the PHR report. Therefore, Figure 6B and 6C This can correspond to multiple PHR entries, where the UE can report PHs for multiple panels or multiple beams within a cell. Furthermore, when the V bit is set to a value of 1, this can indicate that the second PHR is a virtual PHR based on the beam ID reported for the panel.

[0083] Figure 7A and 7B These are schematic diagrams 700 and 710, respectively, illustrating example bitmaps used for wireless communication. More specifically, Figure 7A and7B A bitmap for PHR reporting is shown. (e.g.) Figure 7A As shown, schematic diagram 700 is an example of a bitmap that includes multiple 'C' bits for multiple serving cells for a serving cell index. Figure 7A The diagram shows that a PHR can include multiple bits in a bitmap for multiple beams for each serving cell identified in the PHR. For example... Figure 7A As shown, when the UE is configured for multi-panel operation, additional bits for each serving cell can be used to enhance the PHR. These additional bits indicate the use of PHR or MPE values ​​to report one or more beams. For example, for one of the serving cells in the bitmap (e.g., corresponding to...),... Figure 7A In the bitmap (C4 bit), if the 'X' bit is set to 1, two beams can be reported for the PHR / MPE value of the serving cell. The first beam in the bitmap can be used to calculate the MPE or PHR value for the serving cell. Furthermore, the first beam can correspond to a first beam ID, which can be the currently used beam. Therefore, the MPE and PH values ​​can be associated with the first beam, such as... Figure 7A As shown. The second beam in the bitmap can be used to provide a new beam, which can be used as an alternative or feasible beam for the first beam with MPE events. The second beam can correspond to a second beam ID.

[0084] In some instances, such as Figure 7A As shown, the second beam reported in the PHR can be an alternative beam to the first beam with MPE. Therefore, the second beam can be a candidate beam, and the information for the second beam in the bitmap can be candidate beam information. The second beam provides an alternative beam for the base station. Additionally, for the serving cell in the bitmap (e.g., corresponding to...), Figure 7A In the C6 bit (of the cell), if the 'X' bit is set to 0, a PHR / MPE / beam / panel can be reported for the serving cell. Therefore, the beam can be the beam used to calculate the MPE and PH values. For example... Figure 7A As shown, aspects of this disclosure can add bits to a bitmap in the PHR to report multiple beams for each cell, such as the beams used and alternative beams.

[0085] like Figure 7B As shown, when the UE is configured for multi-panel operation, the PHR report can be enhanced to indicate candidate beams / panels based on the reported PHR / MPE values. For example, as Figure 7BAs shown, if the MPE value (e.g., MPE1) is greater than a threshold, two beams / panels can be reported for the corresponding PHR / MPE value. The first beam can be used to calculate the MPE and PHR values. The second beam can be used as a replacement beam for the first beam with the MPE value. Therefore, in the case of an MPE event, the second beam can be a candidate beam. For example, if the MPE value of the first beam is large, this means that the first beam may be unacceptable, so the PHR can include the second beam as a replacement beam. The first beam can correspond to a first beam ID, and the second beam can correspond to a second beam ID. Furthermore, if the MPE value is less than the threshold, one beam / panel can be reported for the PHR / MPE value. For example, this one beam can be used to calculate either the MPE or PHR value. Therefore, if the MPE value is small, this can correspond to an acceptable beam, and one beam can be reported because a replacement beam is not needed. In some respects, the threshold can be pre-configured or fixed, and if the first beam is reported with an MPE value greater than the threshold, the UE can report the second beam information in the PHR. Otherwise, the UE may choose not to report the second beam information in the PHR.

[0086] As described above, aspects of this disclosure can include additional information related to beam-specific MPE events in the virtual PHR report. For example, when the UE is configured for multi-panel operation, aspects of this disclosure can enhance the virtual PHR report to indicate additional information, such as panel ID, beam ID, MPE value, and / or Pcmax value. In some instances, the virtual PHR calculation can be based on the reported panel ID or beam ID. For example, if the 'P' bit is set to 0, additional information for candidate panels or beams can be reported in the PHR. If the 'P' bit is set to 1, additional information for faulty panels or beams can be reported. As described above, the 'V' field can indicate whether the PH value is based on a real transmission or a reference format. In some instances, if the V bit is set to 1 (which corresponds to the virtual PHR), the PH value can be based on a reference format. In these instances, the Pcmax value may not be reported in the octet next to the PH value. If the V bit is set to 0 (which corresponds to the real PHR), the PH value can be based on a real transmission.

[0087] Figure 8A This is a schematic diagram 800 showing example information reports for a real or virtual PHR. For example... Figure 8AAs shown, when the 'V' bit is set to 0, this corresponds to a real PHR. When the 'V' bit is set to 1, this corresponds to a virtual PHR. Thus, additional information can be reported in the virtual PHR. For example, when the 'V' bit is set to 1, the beam ID or panel ID can be reported in the PHR. In some examples, if the 'V' bit is set to 1, the beam ID or panel ID can be reported in an octet next to the PH value. Furthermore, when the 'P' bit is set to 1, the reported beam ID or panel ID can correspond to a failed beam or panel with an MPE event (e.g., a large MPE value). Similarly, when the 'P' bit is set to 0, this can correspond to a new beam or panel without an MPE event (e.g., a small MPE value or no MPE value).

[0088] Figure 8B This is a schematic diagram 810 showing an example bitmap used for a virtual PHR. (See diagram 810.) Figure 8B As shown, for a virtual PHR, additional information can be reported in the virtual PHR when the 'V' bit is set to 1. For example, when the 'V' bit is set to 1, the PHR can report the beam ID, panel ID, MPE value, or Pcmax value.

[0089] Figure 9 This is a schematic diagram 900 illustrating communication between UE 902 and base station 904. UE 902 may correspond to UE 104, 350, 402 / 422 / 452 and device 1202, and base station 904 may correspond to base station 180, 310, 404 / 424 / 454 and device 1302.

[0090] At 910, UE 902 may transmit one or more uplink beams (e.g., beam 914) to base station 904, or receive one or more downlink beams (e.g., beam 914) from base station 904, wherein at least one MPE event is detected for at least one of the one or more uplink beams or one or more downlink beams. At 912, base station 904 may transmit one or more downlink beams (e.g., beam 914) to UE 902, or receive one or more uplink beams (e.g., beam 914) from UE.

[0091] At 920, UE 902 can detect at least one Maximum Allowable Exposure (MPE) event for one or more uplink beams, one or more downlink beams, or one or more UE panels.

[0092] At 930, UE 902 can configure a power headroom report (PHR) (e.g., PHR 944) that includes at least one of the following when an MPE event is detected: an MPE value associated with an MPE event, at least one beam identifier (ID) corresponding to one or more uplink beams or one or more downlink beams, and at least one panel ID corresponding to one or more UE panels.

[0093] In some aspects, a PHR (e.g., PHR 944) may be associated with a bitmap of a Media Access Control (MAC) control element (MAC-CE) including a first bit for indicating at least one beam ID and a second bit for indicating at least one panel ID. If the first bit is set to a value of 1, at least one beam ID can be indicated in the PHR (e.g., PHR 944), and if the second bit is set to a value of 1, the at least one panel ID can be indicated in the PHR. In some instances, the at least one beam ID may correspond to two or more beam IDs, and the at least one panel ID may correspond to two or more panel IDs. The two or more beam IDs or the two or more panel IDs may be indicated by a bit in the bitmap associated with the PHR (e.g., PHR 944), wherein the bit is set to a value of 1.

[0094] Additionally, the PHR (e.g., PHR 944) may be associated with a bitmap including indications of one or more serving cells corresponding to the at least one beam ID. The bitmap may include bits for each of the one or more serving cells, wherein if the bit for each serving cell is set to 1, the at least one beam ID may correspond to two or more beam IDs, and wherein if the bit for each serving cell is set to 0, the at least one beam ID may correspond to one beam ID. If the MPE value for each of the one or more serving cells is greater than a threshold, the at least one beam ID may correspond to two or more beam IDs, and wherein if the MPE value for each of the one or more serving cells is less than a threshold, the at least one beam ID may correspond to one beam ID.

[0095] Furthermore, the PHR (e.g., PHR 944) may include at least one of a real PHR value or a virtual PHR value. A real PHR value may correspond to a real beam transmission, and a virtual PHR value may correspond to a reference format used for beam transmission. Additionally, the real and virtual PHR values ​​may be associated with the MPE value, the at least one beam ID, the at least one panel ID, or the maximum transmit power (Pcmax) value for at least one of the one or more uplink beams, the one or more downlink beams, or the one or more UE panels.

[0096] In some instances, if the MPE value is less than a threshold, the at least one beam ID or the at least one panel ID may correspond to a candidate beam. The at least one beam ID may correspond to a Synchronization Signal Block (SSB) ID, Channel State Information Reference Signal (CSI-RS) ID, Sounding Reference Signal (SRS) ID, Uplink Spatial Relationship Information ID, or Transmission Configuration Indication (TCI) Status ID. Furthermore, at least one of the at least one beam ID or the at least one panel ID may correspond to an MPE value associated with an MPE event. The PHR (e.g., PHR 944) may also include a maximum transmit power (Pcmax) value associated with the one or more uplink beams, the one or more downlink beams, or at least one of the one or more UE panels.

[0097] At 940, UE 902 may send a PHR (e.g., PHR 944) to base station 904, including at least one of MPE value, at least one beam ID, or at least one panel ID. At 942, base station 904 may receive from UE 902 a PHR (e.g., PHR 944) including at least one of MPE value, at least one beam identifier (ID), or at least one panel ID, wherein the MPE value is associated with an MPE event, the at least one beam ID corresponds to the one or more uplink beams or the one or more downlink beams, and the at least one panel ID corresponds to one or more UE panels.

[0098] Figure 10 This is a flowchart 1000 of a wireless communication method.
