Description

Technical Field

[0001] The present disclosure relates generally to communication systems, and more particularly, to configurations for reporting power headroom reports (PHRs) for simultaneous transmissions. Background Art

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting 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 telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, or even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability, and other requirements (e.g., in the Internet of Things (IoT)). 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Certain aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. These improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0004] A simplified overview of one or more aspects is presented below to provide a basic understanding of these aspects. This summary is not an extensive review of all contemplated aspects. This summary is neither 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 a prelude to a more detailed description presented later.

The apparatus measures one or more resources within the first resource pool and the second resource pool. The apparatus sends a power headroom report (PHR), the power headroom report (PHR) including at least one synchronization signal block (SSB) resource indicator (SSBRI) or channel state indicator reference signal (CSI-RS) resource indicator (CRI) associated with the first resource pool, or at least one SSBRI or CRI associated with the second resource pool.

[0028] In wireless communication, the UE may send a PHR for uplink carrier aggregation. The PHR may be triggered by the MAC layer and may be based on one or more of the following: a set of timers (e.g., phr-PeriodicTimer, phr-ProhibitTimer), a power change greater than a configurable threshold for a path loss reference signal (PL RS) for power control in any uplink component carrier (CC), activation of a secondary cell (SCell), or a change in the active bandwidth portion of a configured CC from sleep to non-sleep. When triggered, the PHR may be reported in a PHR MAC-CE on the first available PUSCH corresponding to the initial transmission of a TB that can accommodate the MAC-CE.

[0029] Aspects presented herein provide configurations for reporting PHR for simultaneous transmissions.Aspects presented herein may allow a UE to report a PHR associated with a first resource pool or a second resource pool.

[0030] The specific embodiments described below in conjunction with the accompanying drawings are descriptions of various configurations and do not represent the only configurations in which the concepts described herein can be practiced. In order to provide a thorough understanding of the various concepts, the detailed description includes specific details. However, these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid blurring these concepts.

[0031] Several aspects of the telecommunication system are also presented with reference to various apparatuses and methods. These apparatuses and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0032] 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, systems on chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gating logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described in this disclosure. One or more processors in a processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other terms, software should be broadly interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.

[0033] Thus, in one or more example aspects, specific implementations and / or use cases, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available media that can be accessed by a computer. For example, such computer-readable media may 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 these types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.

[0034] Although various aspects, specific implementations and / or use cases are described in this application by the illustration of some examples, additional or different aspects, specific implementations and use cases may be generated in many different arrangements and scenarios. The various aspects, specific implementations and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes and packaging arrangements. For example, various aspects, specific implementations and / or use cases can be generated via integrated chip specific implementations and other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, devices that enable artificial intelligence (AI), etc.). Although some examples may or may not be specifically for use cases or applications, the described examples may have a wide range of applicability. Various aspects, specific implementations and / or use cases can be in the range from chip-level or modular components to non-modular, non-chip-level specific implementations, and further to the range of aggregated, distributed or original equipment manufacturer (OEM) equipment or systems in conjunction with one or more technologies herein. In some practical environments, the equipment in conjunction with the various aspects and features described may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily include multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.) The various techniques described herein can be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc., of various sizes, shapes, and configurations.

[0035] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element or network equipment (such as a base station (BS)) or one or more units (or one or more components) that perform base station functionality can be implemented in an aggregated or decomposed architecture. For example, a BS (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a transmit receive point (TRP) or a cell, etc.) can be implemented as an aggregated base station (also referred to as an independent BS or a monolithic BS) or a decomposed base station.

[0036] A converged base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack physically or logically distributed between two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may be implemented as a virtual unit, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0037] Base station operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access and backhaul (IAB) network, an open radio access network (O-RAN (network configuration such as that initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0038] Figure 1 1 is a diagram 100 illustrating an example of a wireless communication system and an access network. The illustrated wireless communication system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs 110 that may communicate directly with a core network 120 via a backhaul link, or indirectly with a core network 120 through one or more disaggregated base station units, such as a near real-time (near RT) RAN intelligent controller (RIC) 125 via an E2 link, or a non-real-time (non-RT) RIC 115 associated with a service management and orchestration (SMO) framework 105, or both. The CU 110 may communicate with one or more DUs 130 via corresponding midhaul links, such as an F1 interface. The DU 130 may communicate with one or more RUs 140 via corresponding fronthaul links. The RU 140 may communicate with corresponding UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0039] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO framework 105) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of these units or an associated processor or controller that provides instructions to the communication interface of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive signals on a wired transmission medium or to transmit signals to one or more of the other units. Additionally, these units may include a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals on a wireless transmission medium or to transmit signals to one or more of the other units, or both.

[0040] In some aspects, CU 110 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by CU 110. CU 110 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 110 may be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 110 may be implemented to communicate with DU 130 for network control and signaling.

[0041] DU 130 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 140. In some aspects, DU 130 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) depending at least in part on a functional split such as that defined by 3GPP. In some aspects, DU 130 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0042] The lower layer functionality may be implemented by one or more RUs 140. In some deployments, the RU 140 controlled by the DU 130 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on functional partitioning (such as lower layer functional partitioning). In such an architecture, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration may enable the implementation of the DU 130 and the CU 110 in a cloud-based RAN architecture (such as a vRAN architecture).

[0043] The SMO framework 105 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 105 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 105 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 190) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 110, DU 130, RU 140, and near-RT RIC 125. In some specific implementations, the SMO framework 105 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 111) via the O1 interface. In addition, in some specific implementations, the SMO framework 105 may communicate directly with one or more RUs 140 via the O1 interface. The SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of the SMO framework 105 .

[0044] The non-RT RIC 115 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 125. The non-RT RIC 115 may be coupled to or in communication with the near-RT RIC 125 (such as via an A1 interface). The near-RT RIC 125 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 110, one or more DUs 130, or both, and the O-eNB with the near-RT RIC 125.

[0045] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 125, the non-RT RIC 115 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 125 and may be received from a non-network data source or from a network function at the SMO framework 105 or the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0046] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Therefore, the base station 102 may include one or more of the CU 110, the DU 130, and the RU 140 (each component is indicated by a dotted line to indicate that each component may be included in the base station 102 or may not be included in the base station). The base station 102 provides an access point to the core network 120 for the UE 104. The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). Small cells include femto cells, pico cells, and micro cells. A network including both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB), which may provide services to a restricted group referred to as a closed subscriber group (CSG). The communication link between RU 140 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to RU 140 and / or downlink (DL) (also known as forward link) transmission from RU 140 to UE 104. The communication link may use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link may be through one or more carriers. For each carrier allocated in a carrier aggregation of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use a spectrum of up to Y MHz (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, etc.) bandwidth. The carriers may be adjacent to each other or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). The component carrier may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).

[0047] Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL wireless wide area network (WWAN) spectrum. The D2D communication link 158 may use one or more side link channels, such as a physical side link broadcast channel (PSBCH), a physical side link discovery channel (PSDCH), a physical side link shared channel (PSSCH), and a physical side link control channel (PSCCH). The D2D communication may be through a variety of wireless D2D communication systems, such as, for example, Bluetooth, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0048] The wireless communication system may also include a Wi-Fi AP 150 that communicates with a UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in a 5 GHz unlicensed spectrum, etc. When communicating in an unlicensed spectrum, the UE 104 / AP 150 may perform a clear channel assessment (CCA) to determine whether a channel is available prior to communication.

[0049] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0050] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6GHz-71GHz), FR4 (71GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0051] In view of the above, unless otherwise specifically stated, if the term "below 6 GHz" or the like is used in this document, it may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, if the term "millimeter wave" or the like is used in this document, it may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.

[0052] The base station 102 and the UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. The base station 102 may send a beamformed signal 182 to the UE 104 in one or more transmit directions. The UE 104 may receive the beamformed signal from the base station 102 in one or more receive directions. The UE 104 may also send a beamformed signal 184 to the base station 102 in one or more transmit directions. The base station 102 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 102 / UE 104 may perform beam training to determine the best receive direction and the best transmit direction for each of the base station 102 / UE 104. The transmit direction and the receive direction of the base station 102 may be the same or different. The transmit direction and the receive direction of the UE 104 may be the same or different.

[0053] The base station 102 may include and / or be referred to as a gNB, a Node B, an eNB, an access point, a transceiver base station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit receive point (TRP), a network node, a network entity, a network equipment, or some other suitable term. The base station 102 may be implemented as an integrated access and backhaul (IAB) node, a relay node, a sidelink node, an aggregated (monolithic) base station with a baseband unit (BBU) (including a CU and a DU) and a RU, or as a decomposed base station including one or more of a CU, a DU, and / or a RU. A set of base stations that may include decomposed base stations and / or aggregated base stations may be referred to as a next generation (NG) RAN (NG-RAN).

[0054] The core network 120 may include an access and mobility management function (AMF) 161, a session management function (SMF) 162, a user plane function (UPF) 163, a unified data management (UDM) 164, one or more location servers 168, and other functional entities. AMF 161 is a control node that processes signaling between UE 104 and the core network 120. AMF 161 supports registration management, connection management, mobility management, and other functions. SMF 162 supports session management and other functions. UPF 163 supports packet routing, packet forwarding, and other functions. UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identity processing, access authorization, and subscription management. One or more location servers 168 are illustrated as including a gateway mobile location center (GMLC) 165 and a location management function (LMF) 166. However, in general, the one or more location servers 168 may include one or more location / positioning servers, which may include one or more of the GMLC 165, the LMF 166, the position determination entity (PDE), the serving mobile location center (SMLC), the mobile positioning center (MPC), etc. The GMLC 165 and the LMF 166 support UE location services. The GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE positioning information. The LMF 166 receives measurements and assistance information from the NG-RAN and the UE 104 via the AMF 161 to calculate the location of the UE 104. The NG-RAN may determine the location of the UE 104 using one or more positioning methods. Positioning the UE 104 may involve signal measurements, position estimation, and optional speed calculations based on these measurements. Signal measurements may be performed by the UE 104 and / or the serving base station 102. The measured signal can be based on a satellite positioning system (SPS) 170 (e.g., one or more of a global navigation satellite system (GNSS), a global positioning system (GPS), a non-terrestrial network (NTN), or other satellite positioning / positioning systems), LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS), sensor-based information (e.g., an atmospheric pressure sensor, a motion sensor), an NR enhanced cell ID (NR E-CID) method, an NR signal (e.g., multi-round trip time (multi-RTT), DL angle of departure (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle of arrival (UL-AoA) positioning) and / or one or more of other systems / signals / sensors.

[0055] Examples of UE 104 include cellular phones, smart phones, 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 devices, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare equipment, implants, sensors / actuators, displays, or any other similarly functional devices. Some of the UEs in UE 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as stations, mobile stations, user stations, mobile units, user units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile user stations, access terminals, mobile terminals, wireless terminals, remote terminals, handsets, user agents, mobile clients, clients, or some other suitable terms. In some scenarios, the term UE may also be applied to one or more supporting devices, such as in a device cluster arrangement. One or more of these devices may access the network collectively and / or individually.

[0056] See again Figure 1 In some aspects, the UE 104 may include a PHR component 198 configured to: receive a configuration including a first resource pool and a second resource pool, each of the first resource pool and the second resource pool corresponding to at least a respective SRS resource set; measure one or more resources within the first resource pool and the second resource pool; and send a PHR including at least one SSBRI or CRI associated with the first resource pool or at least one SSBRI or CRI associated with the second resource pool. In some aspects, the PHR component 198 may be configured to: receive a configuration including the first resource pool and the second resource pool, the configuration configuring the UE with separate or joint PHR triggering and reporting; measure one or more resources within the first resource pool and the second resource pool; and send a PHR associated with the first resource pool or the second resource pool, separate or joint, based on the configuration.

[0057] Although the following description may focus on 5G NR, the concepts described herein may be applicable to other similar areas such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0058] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. Figure 2CFIG250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure can be frequency division duplex (FDD) (wherein, for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL), or can be time division duplex (TDD) (wherein, for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL). Figure 2A , Figure 2C In the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having 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 DL and UL, respectively. Other slot formats 2-61 include a mix of DL, UL and flexible symbols. The slot format is configured for the UE by a received slot format indicator (SFI) (dynamically configured by DL control information (DCI) or semi-statically / statically configured by radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0059] FIG. 2A to FIG. 2D The frame structure is illustrated, and various aspects of the present disclosure may be applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10ms) may be divided into 10 subframes of the same size (1ms). Each subframe may include one or more time slots. A subframe may also include a microslot, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is conventional or extended. For conventional CP, each time slot may include 14 symbols, and for extended CP, each time slot may include 12 symbols. The symbol on the DL may be a CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbol. The symbol on the UL may be a CP-OFDM symbol (for high throughput scenarios) or a discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbol (also known as a single carrier frequency division multiple access (SC-FDMA) symbol) (for power-limited scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and parameter set. The parameter set defines the subcarrier spacing (SCS) and effectively defines the symbol length / duration, which is equal to 1 / SCS.

[0060]

[0061]

[0062] For normal CP (14 symbols / slot), different parameter sets μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For extended CP, parameter set 2 allows 4 slots per subframe. Accordingly, for normal CP and parameter set μ, there are 14 symbols / slot and 2 μ timeslots / subframe. The subcarrier spacing can be equal to 2 μ *15kHz, where μ is parameter set 0 to 4. Therefore, the subcarrier spacing for parameter set μ=0 is 15kHz, and the subcarrier spacing for parameter set μ=4 is 240kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIG. 2A to FIG. 2D An example of a parameter set μ=2 with a normal CP of 14 symbols per slot and 4 slots per subframe is provided. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is about 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency-division multiplexed (see Figure 2B ). Each BWP can have a specific parameter set and CP (normal or extended).

[0063] A resource grid may be used to represent the frame structure. Each slot includes a resource block (RB) (also referred to as a physical RB (PRB)) extending over 12 consecutive subcarriers. The resource grid is divided into a plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0064] like Figure 2A As illustrated in FIG, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).

[0065] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. A physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including 12 consecutive REs in an OFDM symbol 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 a PDCCH monitoring opportunity on a CORESET, wherein the 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. A primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of a frame. The PSS is used by UE 104 to determine subframe / symbol time and physical layer identification. A secondary synchronization signal (SSS) may be within symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and the radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the 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 called SS block (SSB)). The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information not sent over the PBCH (such as the system information block (SIB)), and paging messages.

[0066] like Figure 2C As illustrated, some of the REs carry DM-RS (indicated as R for a particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may send a DM-RS for a physical uplink control channel (PUCCH) and a DM-RS for a physical uplink shared channel (PUSCH). The PUSCH DM-RS may be sent in the first or first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used, the PUCCH DM-RS can be sent in different configurations. The UE may send a sounding reference signal (SRS). The SRS may be sent in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0067] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position 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) acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0068] Figure 3 370 is a block diagram of a base station 310 in an access network communicating with a UE 350. In the DL, Internet Protocol (IP) packets may be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of 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 functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with transmission of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation 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 through HARQ, priority handling, and logical channel prioritization.

[0069] The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transmission channel, forward error correction (FEC) decoding / decoding of the transmission channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The 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-order phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols can then be split into parallel streams. Subsequently, each stream can be mapped to an OFDM subcarrier, each stream is multiplexed with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and each stream is then combined together using an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. Channel estimates may be derived from reference signals and / or channel condition feedback sent by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier with a corresponding spatial stream for transmission.

[0070] At the UE 350, each receiver 354Rx receives a signal through its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined into a single OFDM symbol stream by the RX processor 356. The RX processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a fast Fourier transform (FFT). The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier and the reference signal are recovered and demodulated by determining the signal constellation point most likely to be sent by the base station 310. These soft decisions can be based on channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by base station 310. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0071] The controller / processor 359 may be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0072] Similar to the functionality described in conjunction with DL transmissions performed by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with transmission of upper layer PDUs, error correction through 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 onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0073] Channel estimates derived by the channel estimator 358 from a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a corresponding spatial stream for transmission.

[0074] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318Rx receives a signal through its corresponding antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to the RX processor 370.

[0075] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0076] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform operations related to Figure 1 The PHR component 198 combines various aspects.

[0077] In wireless communication, the UE may send a PHR for uplink carrier aggregation. The PHR may be triggered by the MAC layer and may be based on one or more of the following: a timer set (e.g., phr-PeriodicTimer, phr-ProhibitTimer), a power change greater than a configurable threshold for PL RS for power control in any uplink CC, activation of an SCell, or a change in the active bandwidth portion of the configured CC from sleep to non-sleep. When triggered, the PHR may be reported in a PHR MAC-CE on the first available PUSCH corresponding to the initial transmission of a TB that can accommodate a MAC-CE due to logical channel prioritization (LCP). The PUSCH may be dynamic (e.g., scheduled via DCI) or may be based on a configured grant.

[0078] In the case where the UE is configured with multiple CCs for PUSCH transmission, if multiplePHR is enabled in the RRC, the PHR MAC-CE may include PHRs for more than one CC. Otherwise, the PHR is reported only for the primary cell (PCell) and a single-entry MAC-CE format is used. In the case where the first PUSCH in the first CC carries a PHR MAC-CE for the second CC, the MAC-CE may include an actual PHR or a virtual PHR. The virtual PHR may be based on a reference format. The MAC-CE including the actual PHR or the virtual PHR may be based on whether there is a PUSCH transmission on the second CC at the time of the PHR report (e.g., in the time slot of the first PUSCH), or whether the PUSCH transmission on the second CC is scheduled via a DCI that meets the timeline conditions, otherwise a virtual PHR is reported.

[0079] Figure 4 is a diagram 400 illustrating an example of a PHR MAC-CE. The PHR MAC-CE may include a field 402 indicating the applied power backoff that meets the MPE requirements for FR2.

[0080] Figure 5500 is an example of illustrating a PUSCH repetition based on a single DCI. PUSCH repetitions based on a single DCI may be time division multiplexed (TDM) and may correspond to different transmission parameters (e.g., beam / spatial relationship / TCI state, power control, precoding). PUSCH repetitions scheduled by a single DCI may correspond to two repetition sets, each set having its own beam or power control parameters. In some cases, different repetitions may be associated with the same TB. The two repetition sets may correspond to two SRS resource sets so as to allow PUSCH repetitions scheduled by a single DCI to correspond to two repetition sets. For example, as shown in FIG500, DCI 502 may schedule multiple PUSCH repetitions (e.g., 504, 506), wherein a first repetition set 504 uses a first beam with a first power control parameter set, and a second repetition set 506 uses a second beam with a second power control parameter set. The first repetition set 504 may be for a first TRP, and the second repetition set 506 may be for a second TRP. The first repetition set 504 may be associated with a first SRS resource set having a first uplink beam and an uplink power control parameter set. The second repetition set 506 may be associated with a second SRS resource set having a second uplink beam and an uplink power control parameter set. For both codebook-based and non-codebook-based, the DCI may indicate two beams or two power control parameter sets through two corresponding SRI fields. For codebook-based PUSCH, two TPMI fields may indicate two precoders for two repetition sets.

[0081] In case twoPHRMode is configured (e.g., based on optional UE capabilities), for a CC configured with multi-TRP (mTRP) PUSCH (e.g., configured with two SRS resource sets), two PHR values ​​may be reported in the MAC-CE for the CC, such as Figure 6 600. The triggering and reporting of the PHR may be performed jointly (e.g., not separated by SRS resource set or TRP). One or both of the power headroom (PH) values ​​(e.g., 602, 604) may be real or virtual. If two PUSCH repetitions associated with different SRS resource sets are sent in the same timeslot and in the timeslot in which the MAC-CE is reported, both of the PH values ​​may be real. In some cases, the MAC-CE may be sent in another CC as part of another PUSCH. Figure 6Diagram 600 provides an example of an enhanced single-entry PHR for mTRP MAC-CE with two PH values ​​602, 604, and an example of an enhanced multi-entry PHR for mTRP MAC-CE with multiple PH values ​​(e.g., 602, 604, 606, 608, 610, 612).

[0082] In some cases, such as spatial division multiplexing (SDM) PUSCH based on a single DCI, a single DCI can schedule PUSCH with two DMRS port sets, layers transmitted from two panels with different transmit beams, pre-decoders, or power control parameters. Figure 7 As shown in diagram 700, two layer sets (e.g., 702, 704) can be associated with two SRS resource sets. For example, the first layer 702 can be associated with a first SRS resource set having a first transmit beam and a first TCI state. The second layer 704 can be associated with a first SRS resource set having a second transmit beam and a second TCI state. The DCI may include an SRS resource set indicator field, two SRI fields, and two transmit pre-decoder matrix index (TPMI) fields.

[0083] In some cases, such as in frequency domain multiplexing (FDM) PUSCH based on a single DCI, a single DCI may schedule PUSCH with two RB sets, precoders, or power control parameters sent from two panels with different transmit beams. Figure 8 As shown in diagram 800, two RB sets (e.g., 802, 804) can be associated with two SRS resource sets. For example, a first RB set 802 can be associated with a first SRS resource set, and a second RB set 804 can be associated with a second SRS resource set. Scheme A 812 may include a single redundancy value (RV) 806 that may be configured for joint rate matching. Scheme B 814 may include two RVs, a first RV 808 and a second RV 810, which may be configured for repeated or separate rate matching. The DCI may include an SRS resource set indicator field, two SRI fields, or two TPMI fields.

[0084] In case the PUSCHs overlap in the time domain, such as e.g. Fig. 9As shown in diagram 900, two different PUSCHs (e.g., PUSCH1 902, PUSCH2 904) in the same serving cell or CC may overlap partially or completely at least in the time domain. PUSCH1 902 and PUSCH2 904 may or may not overlap in the frequency domain. This can be achieved through a multi-DCI based mTRP framework, where two PUSCHs can be associated with different coresetPoolIndex values, which can be different from SDM / FDM PUSCH with a single DCI based framework, where simultaneous transmission is within a single PUSCH. In some cases, PUSCH1 902 can be associated with a coresetPoolIndex value of 0 and can be associated with a first SRS resource set, so that PUSCH1 902 is transmitted using a first beam, a first TCI state, a first power control parameter, or a first predecoder. PUSCH2 904 may be associated with a corsetPoolIndex value of 1 and may be associated with a second SRS resource set such that PUSCH2 904 is transmitted using a second beam, a second TCI state, a second power control parameter, or a second precoder.

[0085] Fig.10 An example diagram 1000 of an enhanced maximum allowed emission (MPE) MAC-CE between a UE 1002 and a base station 1004 is illustrated. The base station 1004 may provide a candidate resource pool configuration 1006 to the UE 1002. The base station 1004 may send one or more reference signals 1008 to the UE. The UE 1002 may determine whether a PHR / MPE reporting condition 1010 has been detected. When the P-MPR of the current uplink beam exceeds a threshold, the enhanced MPE MAC-CE may be triggered. The UE 1002 may send a first PHR MAC-CE 1012. The first PHR MAC-CE 1012 may report N P-MPR values ​​associated with N uplink beams. For each of the N P-MPR values, the UE may also report a corresponding SSBRI / CRI selected from a candidate SSB / CSI-RS resource pool configured by the RRC. In some aspects, the UE may support N=1, 2, 3, or 4. The maximum N value supported by the UE may be based on the UE capabilities. The RRC configured resource pool (eg, mpe-ResourcePool-r17) may include a list of up to 64 SBS or CSI-RS resources, where the UE reports up to N SBS or CSI-RS resources.

[0086] Fig.11 An example diagram 1100 of an enhanced MPE report is illustrated. Field 1104 may indicate the SSBRI i or CRI iField 1106 may indicate the power backoff applied to meet the MPE requirement (e.g., if P i is set to 1). In the event that the applied P-MPR value is less than the threshold, field 1102 may be set to 0. Field 1108 indicates the first SSB or CSI-RS associated with the uplink beam for which the MPE is reported within the enhanced MPE report. The MPE configuration (e.g., MPE-Config-FR2-r17) may include an integer value between 1 and 4 for a number N of resources (e.g., numberOfN-r17), and a resource pool (e.g., mpe-ResourcePool-r17) that may be based on the size of the maximum MPE resource (e.g., maxMPE-Resources-r17, MPE-Resource-r17).

[0087] In case of simultaneous PUSCH transmissions, such as SDM / FDM PUSCH for single DCI, two PUSCHs that overlap completely or partially in the time domain for multiple DCI, the UE may use two panels in frequency range 2 (FR2). The MPE values ​​may be different on different panels. The MPE resource pools may be configured separately for separate MPE reports associated with different UE panels. The UE capability for the maximum number of reported MPE values ​​or SSBRI / CRI may be on a per-panel basis or across two panels.

[0088] In the case of multi-DCI based mTRP, where the UE is configured with two coresetPoolIndex values, the UE may be configured with separate or joint PHR triggering and reporting. Separate PHR triggering and reporting may be more applicable to non-ideal backhaul between TRPs, while joint PHR triggering and reporting may be more applicable to the case of good backhaul between TRPs.

[0089] Various aspects presented herein provide configurations for reporting PHRs for simultaneous transmission. Various aspects presented herein may allow a UE to report a PHR associated with a first resource pool or a second resource pool. In some aspects, a UE may be configured to report a PHR including an SSBRI or CRI associated with a first resource pool or an SSBRI or CRI associated with a second resource pool. In some aspects, a UE may be configured to report a PHR associated with a first resource pool or a second resource pool, either individually or jointly.

[0090] The UE may be configured with simultaneous transmission in one CC and may be configured with two separate MPE resource pools, each of which corresponds to an SRS resource set, a coresetPoolIndex value, a UE panel identifier (ID), and a TRP identifier. Each resource pool may be configured with a list of SSB indexes or CSI-RS resource IDs. In some cases, the maximum number of resources per resource pool that the UE can support may be indicated within the UE capability. In some cases, the PHR may include N1 SSBRIs or CRIs and corresponding MPE values ​​from the first MPE resource pool, and N2 SSBRIs or CRIs and corresponding MPE values ​​from the second MPE resource pool. A field in the PHR MAC-CE may indicate whether the reported SSBRI or CRI and the corresponding MPE value can be associated with the first resource pool or the second resource pool. The UE capability may be configured to indicate the maximum value of the supported N1, N2, or N1+N2. For example, the UE may be configured to support a maximum number N1 and a maximum number N2. In some aspects, the UE may be configured to support a maximum number N1+N2. The UE may indicate that the UE can support a maximum number N1, a maximum number N2, or both the maximum number N1 and the maximum number N2. The UE may indicate in a UE capability report to the base station which of at least one of N1, N2 or N1+N2 is supported. The value of N1 or N2 may be configured via RRC signaling from the base station to the UE. In some cases, N1=N2=N, so that the UE can report N pairs of SSBRI / CRI and N corresponding pairs of MPE values. This can be used as an indication that the UE can simultaneously send two uplink beams corresponding to the pair. This can be indicated based on the two uplink beams being reported as a pair or being associated with each other. The first SSB / CSI-RS resource of each pair may be selected from the first resource pool and may be associated with at least one of the first SRS resource set, coresetPoolIndex value, UE panel ID, TRP ID, or the second SSB / CSI-RS of the pair may be selected from the second resource pool and associated with at least one of the second SRS resource set, coresetPoolIndex value, UE panel ID, or TRP ID.

[0091] Fig.12An example diagram 1200 of a UE configured with two separate resource pools is illustrated. For example, the UE may be configured with a first resource pool 1202 and a second resource pool 1204. For the first resource pool 1202, the UE may select N1 SSB / CSI-RS resources so that the UE may report MPE values ​​associated with the corresponding uplink beams. For the second resource pool 1204, the UE may select N2 SSB / CSI-RS resources so that the UE may report MPE values ​​associated with the corresponding uplink beams. The UE may send a PHR MAC-CE 1206. The PHR MAC-CE may include N1 SSBRI / CRIs and N1 corresponding MPE values, N2 SSBRI / CRIs and N2 corresponding MPE values, or N pairs of SSBRI / CRIs and N corresponding pairs of MPE values. In some cases, such as cases of uplink carrier aggregation and multi-entry PHR, the MAC-CE may include information of the PHR MAC-CE on a per-CC basis. For example, the MAC-CE (e.g., 1206) may include N1 SSBRI / CRIs and N1 corresponding MPE values, N2 SSBRI / CRIs and N2 corresponding MPE values, or N pairs of SSBRI / CRIs and N corresponding pairs of MPE values ​​for each CC in the CC, so that the information for each CC in the CC can be cascaded into one MAC-CE.

[0092] In the case of multi-DCI based mTRP, such that the UE is configured with two coresetPoolIndex values, and if the UE is configured with separate PHR triggering and reporting (e.g., PHR MAC-CE corresponds to one coresetPoolIndex value), then if the PHR MAC-CE is associated with coresetPoolIndex value 0, the UE reports N1 SSBRI / CRIs and corresponding MPE values ​​associated with the first MPE resource pool. If the PHR MAC-CE is associated with coresetPoolIndex value 1, the UE reports N2 SSBRI / CRIs and corresponding MPE values ​​associated with the second MPE resource pool. For example, refer to Fig.131300, the UE may be configured with a first resource pool 1302 and a second resource pool 1304. The PHR MAC-CE 1306 may include N1 SSBRI / CRIs and N1 corresponding MPE values. The PHR MAC-CE 1308 may include N2 SSBRI / CRIs and N2 corresponding MPE values. The association of the PHR MAC-CE with the coresetPoolIndex value may be based on at least one of the fields in the MAC-CE (e.g., indicated by the PHR MAC-CE) or based on the coresetPoolIndex value with which the PUSCH carrying the MAC-CE is associated.

[0093] In the case of multi-DCI based mTRP, so that the UE is configured with two coresetPoolIndex values, the UE may be configured with separate or joint PHR triggering and reporting. The UE may be configured with separate or joint PHR triggering and reporting via RRC signaling. In the case where the UE is configured with separate PHR triggering and reporting, the UE may be configured with a separate PHR configuration including a separate timer value (e.g., periodic timer, prohibit timer). In some cases, one PHR configuration may be associated with one coresetPoolIndex value. In some cases, when PHR is triggered for a coresetPoolIndex value, the PHR MAC-CE may include a PHR report for one or more CCs configured with the coresetPoolIndex value. In the case where the UE is configured with joint PHR triggering and reporting, when PHR is triggered for a CC configured with 2 coresetPoolIndex values, the PHR MAC-CE may include two PHR reports, one of which is associated with a coresetPoolIndex value of 0 and the other is associated with a coresetPoolIndex value of 1.
