Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for power headroom reporting associated with simultaneous transmissions on multiple uplink channels. 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 that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0003] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0004] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0030] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art.

[0032] The present disclosure may be easily used as a basis for modifying or designing other structures for performing the same purpose of the present disclosure. Such equivalent constructions do not depart from the scope of the appended claims. The characteristics of the concepts disclosed herein (both their organization and method of operation) and the associated advantages are better understood from the following description when considered in conjunction with the accompanying drawings. Each of the figures in the accompanying drawings is provided for the purpose of illustration and description and not as a definition of the limitations of the claims.

[0033] Although various aspects are described in the present disclosure by illustrating some examples, such aspects can be implemented in many different arrangements and scenarios. The technology described herein can be implemented using different platform types, devices, systems, shapes, sizes and / or packaging arrangements. For example, some aspects can be implemented via integrated chip implementations or other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / shopping equipment, medical equipment, and / or artificial intelligence devices). Various aspects can be implemented in chip-level components, modular components, non-modular components, non-chip-level components, device-level components and / or system-level components. The equipment incorporating the various aspects and features described may include additional components and features for implementing and practicing the various aspects claimed and described. For example, the transmission and reception of wireless signals may include one or more components (e.g., hardware components, including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders and / or summers) for analog and digital purposes. The various aspects described herein can be practiced in various devices, components, systems, distributed arrangements and / or end-user devices of different sizes, shapes and compositions.

[0034] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0035] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or post-5G (e.g., 6G) RAT.

[0036] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0037] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.

[0038] In some examples, the network node 110 can provide communication coverage for a specific geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 can provide communication coverage for a macro cell, a micro cell, a femto cell, and / or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by a UE 120 with a service subscription. A micro cell can cover a relatively small geographic area and can allow unrestricted access by a UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by a UE 120 associated with a femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell can be referred to as a macro network node. A network node 110 for a micro cell can be referred to as a micro network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0039] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC) or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not another base station function. Thus, a single device may include more than one base station.

[0040] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown, a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0041] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0042] The network controller 130 may be coupled to or communicate with a collection of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be, or may include, a CU or a core network device.

[0043] UE 120 can be dispersed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.

[0044] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0045] Generally speaking, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, an air interface, etc. Frequency may be referred to as a carrier, a frequency channel, etc. In a given geographic area, each frequency may support a single RAT to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0046] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0047] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 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).

[0048] 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, so 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 FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0049] In view of the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term can be broadly referred to as frequencies that can be lower than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term can be broadly referred to as frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0050] In some aspects, a UE (e.g., UE 120) may include a communication manager 140. As described in greater detail elsewhere herein, the communication manager 140 may receive configuration information corresponding to a power headroom report associated with simultaneous transmissions on a plurality of uplink channels, the configuration information indicating a maximum total transmit power limit associated with the simultaneous transmissions; and send a medium access control (MAC) control element (MAC CE) including at least one power headroom report (PHR) corresponding to the plurality of uplink channels based at least in part on the configuration information. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0051] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send configuration information corresponding to a power headroom report associated with simultaneous transmission on multiple uplink channels, the configuration information indicating a maximum total transmit power limit associated with the simultaneous transmission; and receive a MAC CE including at least one PHR corresponding to the multiple uplink channels based at least in part on the configuration information. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0052] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 Different than described.

[0053] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0054] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a set of corresponding antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0055] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0056] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0057] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more groups of antenna elements, and / or one or more antenna arrays, etc. An antenna panel, an antenna group, a group of antenna elements, and / or an antenna array may include one or more antenna elements (in a single housing or multiple housings), a group of coplanar antenna elements, a group of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components).

[0058] Each of the antenna elements may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element that is cross-polarized with a second sub-element, which can be used to independently transmit a cross-polarized signal. The antenna elements may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between the antenna elements may be such that signals having desired wavelengths, respectively transmitted by the antenna elements, may interact or interfere (e.g., to form a desired beam). For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half wavelength, or other fraction of a wavelength of the spacing between adjacent antenna elements to allow interaction or interference of signals transmitted by separate antenna elements within the desired range.

[0059] Antenna elements and / or sub-elements may be used to generate beams. A "beam" may specify a wireless signal that is transmitted in a direction, such as in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicating one or more aspects of a directional signal, a direction associated with the signal, and / or a set of directional resources associated with the signal.

[0060] As indicated above, antenna elements and / or sub-elements can be used to generate beams. For example, antenna elements can be individually selected or deselected for transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers. Beamforming includes generating beams using multiple signals on different antenna elements, wherein one or more or all of the multiple signals are shifted in phase relative to each other. The formed beams can carry physical or higher layer reference signals or information. When each of the multiple signals is radiated from the corresponding antenna element, the radiated signals interact, interfere (constructively and destructively) and amplify with each other to form the resulting beam. The shape (such as the amplitude, width and / or the presence of side lobes) and direction (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shift or phase offset of the multiple signals relative to each other.

[0061] Beamforming may be used for communication between a UE and a network node, such as for millimeter wave communication, etc. In this case, the network node may provide the UE with a configuration of a transmit configuration indicator (TCI) state, which indicates beams that may be used by the UE, such as for receiving a physical downlink shared channel (PDSCH). The network node may indicate an activated TCI state to the UE, which the UE may use to select a beam for receiving the PDSCH.

[0062] The beam indication may be or include a TCI state information element, a beam identifier (ID), spatial relationship information, a TCI state ID, a closed loop index, a panel ID, a TRP ID, and / or a sounding reference signal (SRS) set ID, etc. The TCI state information element (referred to herein as TCI state) may indicate information associated with a beam such as a downlink beam. For example, the TCI state information element may indicate a TCI state identifier (e.g., tci-StateID), a quasi-co-location (QCL) type (e.g., qcl-Type1, qcl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, qcl-TypeD, etc.), a cell identifier (e.g., ServCellIndex), a bandwidth part identifier (bwp-Id), a reference signal identifier (such as CSI-RS (e.g., NZP-CSI-RS-ResourceId, SSB-Index, etc.)), etc. The spatial relationship information may similarly indicate information associated with an uplink beam.

[0063] The beam indication can be a joint or separate downlink (DL) / uplink (UL) beam indication in a unified TCI framework. In some cases, the network can use at least UE-specific (unicast) downlink control information (DCI) to indicate a joint or separate DL / UL beam indication from an active TCI state, thereby supporting beam indication based on layer 1 (L1). In some cases, existing DCI formats 1_1 and / or 1_2 can be reused for beam indication. The network may include a support mechanism for the UE to confirm successful decoding of the beam indication. For example, an acknowledgment / negative acknowledgment (ACK / NACK) of a PDSCH scheduled by a DCI carrying a beam indication can also be used as an ACK for the DCI.

[0064] Beam indication may be provided for carrier aggregation (CA) scenarios. In a unified TCI framework, the network may support information for common TCI state ID updates and activations to provide common QCL and / or one or more common UL transmit spatial filters across a set of configured component carriers (CCs). This type of beam indication may be applicable to intra-band CA as well as joint DL / UL beam indication and separate DL / UL beam indication. A common TCI state ID may mean that a reference signal (RS) determined according to a TCI state indicated by a common TCI state ID is used to provide a QCL type D indication and determine a UL transmit spatial filter across a set of configured CCs.

[0065] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by a TX MIMO processor 266, where applicable, further processed by a modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, reference Figures 6 to 13 ) or any aspect of any of the methods described herein.

[0066] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform the operations described herein (e.g., reference 2 Figures 6 to 13 ) or any aspect of any of the methods described herein.

[0067] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Fig.10 The process of 1000 Fig.11 1100 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Fig.10 The process of 1000 Fig.11 The process 1100 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0068] In some aspects, a UE (e.g., UE 120) includes: a component for receiving configuration information corresponding to a power headroom report associated with simultaneous transmission on multiple uplink channels, the configuration information indicating a maximum total transmit power limit associated with the simultaneous transmission; and / or a component for sending a MAC CE including at least one PHR corresponding to the multiple uplink channels based at least in part on the configuration information. The components for the UE to perform the operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0069] In some aspects, the network node includes: a component for sending configuration information corresponding to a power headroom report associated with simultaneous transmission on multiple uplink channels, the configuration information indicating a maximum total transmit power limit associated with the simultaneous transmission; and / or a component for receiving a MAC CE including at least one PHR corresponding to the multiple uplink channels based at least in part on the configuration information. In some aspects, the components for the network node to perform the operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0070] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0071] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different than described.

[0072] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components 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 RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or a "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0073] An aggregated base station (e.g., an aggregated network node) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) can be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed across one or more other network nodes. The DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0074] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that may be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0075] Figure 3 3 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0076] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0077] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split 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, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0078] Each DU 330 may correspond to a logical unit including one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0079] Each RU 340 may implement lower layer functionality. In some deployments, a RU 340 controlled by a DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. based on a functional split (e.g., a functional split defined by 3GPP) (such as a lower layer functional split). In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0080] The SMO framework 305 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 305 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 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) 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 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via an O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0081] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 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 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0082] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received at the SMO framework 305 or the non-RT RIC 315 from a non-network data source or from a network function. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0083] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different than described.

[0084] Uplink power control may determine the power used for Physical Uplink Shared Channel (PUSCH) transmissions, Physical Uplink Control Channel (PUCCH) transmissions, Sounding Reference Signal (SRS) transmissions, and / or Physical Random Access Channel (PRACH) transmissions.

[0085] The UE may use the parameter set configuration with index j and the PUSCH power control adjustment state with index l to transmit PUSCH on the active uplink bandwidth part (BWP) b of carrier f of serving cell c. The UE may set the PUSCH transmit power P in PUSCH transmission opportunity i to PUSCH,b,f,c (i,j,q d ,l) is determined as:

[0086]

[0087] About PUSCH transmission power P PUSCH,b,f,c (i,j,q d ,l)(in dB),P O_PUSCH,b,f,c (j) can represent the P0 value used to control the received power level, α b,f,c (j) may represent the value of α used for partial path loss (PL) compensation, PL b,f,c (q d ) may represent a sequence based at least in part on the index q d The measured path loss value of the downlink reference signal, Δ TF,b,f,c (i) may depend on the resource allocation and MCS of PUSCH, and f b,f,c(i, l) may represent closed-loop power control based at least in part on a transmit power control (TPC) command with a closed-loop index l (also referred to as a closed-loop adjustment state). “RB” is an abbreviation for “Resource Block”.

[0088] For PUSCH transmission, an uplink power control parameter set may be configured. The uplink power control parameter may include a twoPUSCH-PC-AdjustmentStates parameter, which may be configured when there are two separate loops for closed-loop power, and TPC commands may be applied separately for the two separate loops. The uplink power control parameter may include a set of P0 and α values ​​(p0-AlphaSets) for open-loop power control, where each member of the set may have an ID (p0-PUSCH-AlphaSetId: 0, 1, ..., 29). The uplink power control parameter may include a list of path loss reference signals, where each member of the list may have an ID (pusch-PathlossReferenceRS-Id: 0, 1, ..., 3). The uplink power control parameter may include a list of SRI-PUSCH mappings, where "SRI" refers to an SRS reference indicator or an SRS resource indicator, and each member of the list may have an ID (sri-PUSCH-PowerControlId: 0, ..., 15). In addition, each member of the list can be configured at least in part based on the sri-PUSCH-PowerControlId parameter, which can be used as a code point for the SRI field in the downlink control information (DCI). When the value of the SRI field in the uplink DCI scheduling PUSCH is x, then the uplink power control (ULPC) parameters (e.g., PL RS, P0 and α, closed loop index) corresponding to the sri-PUSCH-PowerControlId equal to x can be used for PUSCH transmission. The SRI field can be up to four bits and can indicate up to 16 values ​​of x, depending on the configuration of the SRI field.

[0089] Because the UE may emit RF waves, microwaves, and / or other radiation, the UE is generally subject to regulatory RF safety requirements that specify specific guidelines or maximum permissible exposure (MPE) limits that constrain various operations that the UE may perform. For example, when the UE is transmitting, RF emissions may generally increase, and may further increase in situations where the UE is performing frequent transmissions and / or high-power transmissions, etc. Therefore, because frequent and / or high-power transmissions may result in significant RF emissions, regulatory agencies (e.g., the Federal Communications Commission (FCC) in the United States) provide information related to acceptable RF radiation exposure when the UE is communicating using different radio access technologies.

[0090] For example, when the UE is communicating using a radio access technology operating in a frequency range below 6 GHz, the applicable RF exposure parameter is the specific absorption rate (SAR), which refers to the rate at which energy is absorbed by a human body when exposed to RF energy (e.g., power absorbed per unit mass, which may be expressed in terms of watts per kilogram (W / kg)). SAR requirements typically specify that the total radiated power of the UE be kept below a certain level to limit the heating that may occur when absorbing RF energy. In another example, when the UE is communicating using a radio access technology operating in a high frequency range, such as a millimeter wave (mmW) frequency range, the applicable RF exposure parameter is power density, which may be adjusted to limit heating of the UE and / or nearby surfaces.

[0091] Therefore, the UE may take measures to meet MPE limits, which are usually regulatory requirements defined in terms of aggregate exposure over a certain amount of time, and the aggregate exposure may be averaged over a moving integration window (or moving time window). For example, the UE may be subject to an average power limit (P limit ), the average power limit corresponding to the average power that meets the MPE limit if the UE were to transmit substantially continuously over a mobile integration window of N seconds (e.g., 100 seconds). In some cases, the UE may reduce the transmit power by applying a power management maximum power backoff (P-MPR) to meet the MPE limit. The P-MPR may refer to a maximum allowed UE output power reduction for a serving cell. In some aspects, the UE reports the power backoff level due to the P-MPR as an MPE value.

[0092] The UE may report the P-MPR to the network node to facilitate efficient communication. The P-MPR may be reported as part of the PHR, which may be reported using the PHR MAC CE. For example, the PHR MAC CE may be a MAC CE enhanced to report P-MPR information. In some cases, a two-bit MPE field may be provided by reusing a reserved bit to indicate the power backoff applied to meet the MPE requirement.

[0093] The PHR report may also report a PHR value, which may correspond to the difference between the actual transmit power at which the UE is operating and the maximum configured power. A PHR report may be triggered when the power backoff due to the P-MPR for the cell has changed by more than a threshold since the last transmission of the PHR. The threshold may be specified as the parameter phr-Tx-PowerFactorChange.

[0094] The power headroom may indicate the amount of remaining transmit power available to the UE in addition to the power used for current transmission. The power headroom may be based at least in part on the difference between the UE maximum transmit power and the PUSCH transmit power. The PHR may be a type 1 report for PUSCH, a type 3 report for SRS, or a type 2 report for PUCCH. For example, the type of UE PHR may include a type 1 UE power headroom valid for PUSCH transmission opportunity i on active UL BWP b of carrier f of serving cell c or a type 3 UE power headroom valid for SRS transmission opportunity i on active UL BWP b of carrier f of serving cell c. Thus, the PHR may be determined for a component carrier and / or a serving cell.

[0095] The UE may determine whether the PHR for the activated serving cell is based at least in part on the actual transmission. The actual transmission may be determined at least in part based on the configured grant and higher layer signaling of the periodic / semi-persistent sounding reference signal transmission or the DCI received by the UE. The UE may determine whether the PHR for the activated serving cell is based at least in part on the reference format. The reference format may be determined at least in part based on the configured grant and higher layer signaling of the periodic / semi-persistent sounding reference signal transmission or the DCI received by the UE. The UE may determine whether the PHR for the activated serving cell is based at least in part on the reference format. The PHR for the activated serving cell may be referred to as a virtual PHR and / or may be provided via a virtual PHR report.

[0096] When the UE determines that the Type 1 PHR for the activated serving cell is based at least in part on the actual PUSCH transmission, then for PUSCH transmission opportunity i on the active uplink BWP b of carrier f of serving cell c, the UE may calculate the Type 1 PHR as:

[0097]

[0098] Regarding Type 1 PHR (in dB) based at least in part on the actual PUSCH transmission, may represent the maximum output power configured by the UE after backoff due to power management (eg, backoff due to maximum power backoff), and P O_PUSCH,b,f,c (j) α b,f,c (j), PL b,f,c (q d ), Δ TF,b,f,c (i) and f b,f,c (i, l) may be a parameter used to determine the PUSCH transmission power.

[0099] The UE may be configured with multiple component carriers for PUSCH transmission. When the multiplePHR parameter is enabled via radio resource control (RRC) signaling, the PHR MAC CE may include PHRs for more than one component carrier. Otherwise, the PHR may be a report for a primary cell (PCell) and a single-entry PHR MAC CE format may be used. When the first PUSCH in the first component carrier carries the PHR MAC CE, the PHR MAC CE may include an actual PHR or a virtual PHR (based on the reference format) for the second component carrier. When PUSCH transmission is performed on the second component carrier during power headroom reporting (e.g., in the time slot of the first PUSCH), and the PUSCH transmission on the second component carrier is scheduled by a DCI that meets the timeline condition, the PHR MAC CE may include an actual PHR. Otherwise, the MAC CE may include a virtual PHR.

[0100] The PHR MAC CE may be a single-entry PHR MAC CE or a multi-entry PHR MAC CE. A single-entry PHR MAC CE may include a Power Headroom (PH) field and a P CMAX,f,c field, the power headroom (PH) field may indicate the PH level of the PCell. CMAX,f,c The PH field may indicate the PH used to calculate the previous PH field. CMAX,f,c The multi-entry PHR MAC CE may include entries for the PCell and multiple SCells. For example, for a PCell or a given SCell, the multi-entry PHR MAC CE may include the corresponding PH field, P CMAX,f,cfield, a “V” value and a “P” value, wherein the “V” value may indicate whether the PH value in the PH field corresponds to a real transmission or a reference format, and the “P” value may indicate whether power backoff is applied due to power management.

[0101] In some cases, the legacy PHR MAC CE may be used for single cell reporting. Figure 4 406 is a diagram illustrating an example 400 of a single-cell MPE report using a PHR 402 of a MAC CE according to the present disclosure. As shown, the PHR 402 may include a power backoff indication field (referred to as a "P field" or "P bit") 404 that may be used to indicate power backoff applied due to power management. In some cases, the P field 404 may be used to indicate reporting of a measured value of the P-MPR. For example, if the P-MPR level is being reported, the P field may be set to a specified value (e.g., 1), in which case the P-MPR value may be reported. If the P-MPR level is not to be reported (e.g., if the power backoff is less than a specified value), the P field may be set to a different specified value (e.g., 0), and a reserved bit (shown as "R") 406 may be present. In some cases, if MPE reporting is not configured, then if power backoff due to power management has not been applied, the corresponding P-MPR may be reported. CMAX,f,c Field 408 has a different value, then P = 1. CMAX,f,c Field 408 may include the value P CMAX,f,c , which may represent the maximum output power configured by the UE after backoff due to power management of carrier f with respect to serving cell c (e.g., backoff due to maximum power backoff). The PHR 402 also includes a power headroom field 410 indicating a power headroom (PH) level. CMAX,f,c Field 408 may be used to calculate a previous PH field. PHR 402 also includes an MPE field 412. If MPE reporting is configured and if P field 404 is set to 1, MPE field 412 indicates the power backoff applied to meet the MPE requirement. MPE field 412 indicates the index of the corresponding measurement value of the P-MPR level in decibels (dB). If MPE reporting is not configured, or if the P field is set to 0, R bits are present instead.

[0102] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 Different than described.

[0103] A UE may be configured with multiple component carriers for uplink transmission. Figure 55 is a diagram illustrating examples 500 and 502 of MPE reports for multi-cell single-panel PHR reporting. As shown, the MPE report may include a bitmap 504 including a cell activation status field 506. Each cell activation status field 506 indicates a serving cell index C i (Shown as "C1", "C2", ...) The cell activation status field (referred to as the "C field") 506 may indicate the serving cell and / or component carrier corresponding to the PHR 508 being reported.

[0104] When the multiplePHR parameter is enabled via radio resource control (RRC) signaling, the PHR MAC CE may include PHRs for more than one component carrier. Otherwise, the PHR may be a report for a primary cell (PCell) and a single-entry PHR MAC CE format may be used. When the first uplink channel in the first component carrier carries the PHR MAC CE, for the second component carrier, the PHR MAC CE may include an actual PHR 508 or a virtual PHR (based on a reference format). Each PHR 508 may include a virtual PHR indication field 510 indicating whether the corresponding PH value is based on a real transmission or a reference format. When an uplink transmission is performed on the second component carrier during a power headroom report (e.g., in a time slot of a first uplink transmission), and the uplink transmission on the second component carrier is scheduled by downlink control information (DCI) that satisfies the timeline condition, the PHR MAC CE may include an actual PHR. Otherwise, the MAC CE may include a virtual PHR. For a virtual PHR, the PHR is not reported. CMAX .

[0105] In an environment of a UE equipped with multiple antenna panels and configured to communicate using MIMO technology and / or a UE equipped to communicate via multiple component carriers, the power headroom report described above may face inefficiency issues. In such cases, the UE may include multiple antenna panels, each having an antenna port set that facilitates the generation of one or more beams. By reporting MPE information (e.g., P-MPR value or MPE value) by serving cell, differences in MPE information that may exist for one beam, port and / or panel relative to another beam, port and / or panel may be ignored. Additionally, in some cases, a total transmit power limit for panels for all UEs may be configured. In this case, the total transmit power can be shared between these panels. In many cases, the PHR format may not include the difference between the maximum transmit powers of different panels. Therefore, the network node may not know the distribution of transmit power between panels, thereby reducing network efficiency and / or network performance.

[0106] Some aspects of the techniques and apparatus described herein relate to power headroom reports associated with simultaneous transmissions on multiple uplink channels. For example, in some aspects, a UE may receive configuration information corresponding to a power headroom report associated with simultaneous transmissions on multiple uplink channels. The configuration information may indicate a maximum total transmit power limit associated with the simultaneous transmissions. The UE may send a MAC CE including at least one PHR corresponding to the multiple uplink channels based at least in part on the configuration information. In this way, the network may be made aware of the transmit power distribution between multiple panels associated with multiple simultaneous uplink transmissions. Therefore, some aspects may improve network efficiency and / or enhance overall performance, thereby having a positive impact on network performance.

[0107] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 Different than described.

[0108] Figure 6 600 is a diagram illustrating an example of power headroom reporting associated with simultaneous transmission on multiple uplink channels according to the present disclosure. As shown, a UE 602 and a network node 604 may communicate with each other. The UE 602 may be, similar to, or include Figures 1 to 3 The network node 604 may be, be similar to, or include the UE 120 depicted in FIG. Figure 1 and Figure 2 The network node 110 depicted in Figure 3 CU 310, depicted in Figure 3 DU 330 and / or Figure 3 The RU 340 depicted in the figure may be included in the network node, the CU, the DU or the RU.

[0109] As shown by reference numeral 606, the network node 604 may send and the UE 602 may receive configuration information corresponding to a power headroom report associated with simultaneous transmission on multiple uplink channels. The configuration information may indicate a maximum total transmit power limit (Pt) associated with the simultaneous transmission. In some aspects, the configuration information may be sent using an RRC message. The configuration information may indicate a set of parameters to be reported. The configuration information may indicate one or more aspects associated with reporting MPE information. For example, the configuration information may indicate resources to be used for reporting power headroom information, one or more parameters to be reported, a format associated with at least one PHR, one or more MAC CE configurations to be used for at least one PHR, a trigger condition for reporting power headroom information, and / or a prohibition timer for facilitating avoiding too frequent reporting of power headroom information, and the like.

[0110] As shown by reference numeral 608, UE 602 may send and network node 604 may receive a MAC CE including at least one PHR corresponding to the plurality of uplink channels. UE 602 may send the MAC CE based at least in part on the configuration information. In some aspects, UE 602 may report two PHRs separately, as if the two uplink channels were not sent simultaneously. For example, the at least one PHR may include a first PHR corresponding to a first uplink channel of the plurality of uplink channels and a second PHR corresponding to a second uplink channel of the plurality of uplink channels.

[0111] In some aspects, the UE 602 may calculate the PHR value assuming a maximum total transmit power for each uplink channel. For example, the first PHR may indicate a first power headroom value corresponding to the first uplink channel, and the second PHR may indicate a second power headroom value corresponding to the second uplink channel. Each of the first power headroom value and the second power headroom value may be based on the maximum total transmit power limit. In some aspects, the first power headroom value may also be based on a first set of parameter values ​​of a parameter set associated with the first uplink channel. The second power headroom value may also be based on a second set of parameter values ​​of the parameter set associated with the second uplink channel. The parameter set may include a maximum power backoff (MPR), an additional MPR (A-MPR), a P-MPR, or an additional power adjustment parameter ΔT C At least one of .

[0112] In some aspects, the at least one PHR may indicate a first set of PHR parameter values ​​of a PHR parameter set corresponding to the first uplink channel and a second set of PHR parameter values ​​of the PHR parameter set corresponding to the second uplink channel. The PHR parameter set may include at least one of a power headroom, a configured maximum output power (Pcmax), or a P-MPR. In some aspects, the first set of PHR parameter values ​​may include a first Pcmax value, and the second set of PHR parameter values ​​may include a second Pcmax value. The sum of the first Pcmax value and the second Pcmax value may be less than the maximum total transmit power limit.

[0113] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 Different than described.

[0114] Figure 7 is a diagram illustrating an example 700 of a MAC CE with two PHRs according to the present disclosure. Example 700 is combined with Figure 6The described aspects are associated with the embodiment in which two PHRs may be included in the MAC CE to separately report power headroom information associated with two simultaneously transmitted channels.

[0115] The MAC CE may include a first PHR 702 corresponding to a first uplink channel and a second PHR 704 corresponding to a second uplink channel. The PHR 702 and the PHR 704 may include power backoff indication fields 706 and 708 (referred to as "P fields" or "P bits"), respectively, which may be used to indicate power backoff applied due to power management. The PHR 702 and the PHR 704 may include virtual indicator fields 710 and 712 ("V fields"), respectively, indicating whether the PH value is based on a real transmission or a reference format. The PHR 702 and the PHR 704 may also include MPE fields 714 and 716, respectively, and Pcmax fields 718 and 720, respectively. As shown, the PHR 702 also includes a PH field 722, which indicates a power headroom level associated with the first uplink channel. Similarly, the PHR 704 includes a PH field 724, which indicates a power headroom level associated with the second uplink channel.

[0116] In some cases, the P fields 706, 708 may be used to indicate reporting of a measured value of the P-MPR. For example, if the P-MPR level is being reported, the P fields 706, 708 may be set to a specified value (e.g., 1), in which case the P-MPR value may be reported. If the P-MPR level is not to be reported (e.g., if the power backoff is less than a specified value), the P fields 706, 708 may be set to a different specified value (e.g., 0), and a reserved bit (shown as "R") may be present. In some cases, if MPE reporting is not configured, then if the power backoff due to power management has not been applied, the corresponding P CMAX If field 718 or 720 has a different value, then P=1. CMAX Fields 718, 720 may include the value P CMAX,f,c , which may represent the maximum output power configured by the UE after a backoff due to power management of carrier f with respect to serving cell c (e.g., a backoff due to maximum power backoff). If MPE reporting is configured and if the P field 706 or 708 is set to 1, the corresponding MPE field 714 or 716 may indicate the power backoff applied to meet the MPE requirement. The MPE field 714 or 716 may indicate the index of the corresponding measurement value of the P-MPR level in decibels. If MPE reporting is not configured, or if the P field is set to 0, R bits may be present instead.

[0117] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 Different than described.

[0118] Figure 8 is a diagram illustrating an example 800 of a MAC CE with two PHRs according to the present disclosure. Example 800 is combined with Figure 6 Aspects of description and Figure 7 800, where two PHRs may be included in the MAC CE to separately report power headroom information associated with two simultaneously transmitted channels. In example 800, the portion of the MAC CE shown may be associated with Figure 7 The same as shown, except that the UE may jointly report two PHRs taking into account the reference power split of the total transmit power limit.

[0119] For example, as shown, the MAC CE may include a first PHR 802 associated with a first uplink channel and a second PHR 804 associated with a second uplink channel. PHR 802 and PHR 804 may include a combination of Figure 7 804 may include a Pcmax field 806, which may include a reserved bit (shown as "R") in aspects where a configured maximum output power (Pcmax) is reported in a Pcmax field 808 associated with the PHR 802.

[0120] In some aspects, for example, the first PHR 802 may indicate a first power headroom value corresponding to the first uplink channel, and the second PHR may indicate a second power headroom value corresponding to the second uplink channel, wherein each of the first power headroom value and the second power headroom value is based on a reference power split of the maximum total transmit power limit between the first uplink channel and the second uplink channel. For example, the maximum total transmit power limit may be split in half, and each half of the maximum total transmit power limit will be applied to one of the uplink channels. In some aspects, PHRs 802 and 804 may each report P cmax,f,c (i) A value that uses half of the maximum total transmit power limit and uses the MPR, A-MPR, P-MPR, DT associated with the corresponding uplink channel. C A collection of values ​​to calculate.

[0121] In some aspects, for example, the first power headroom value may be based on a reference power that includes half of the maximum total transmit power limit, and the second power headroom value may be based on the reference power. The UE may report two sets of PHRs, P-MPR values ​​for two uplink channels, and a P-MPR value common to the two uplink channels. cmax,f,c (i) value. For example, in some aspects, the first power headroom value may also be based on a first set of parameter values ​​of a parameter set associated with the first uplink channel, and the second power headroom value may also be based on a second set of parameter values ​​of the parameter set associated with the second uplink channel. The parameter set may include MPR, A-MPR, P-MPR, or additional power adjustment parameter ΔT C At least one of .

[0122] In some aspects, the PHRs 802 and 804 may indicate a configured maximum output power associated with the first uplink channel and the second uplink channel, and a first set of PHR parameter values ​​of a PHR parameter set corresponding to the first uplink channel and a second set of PHR parameter values ​​of the PHR parameter set corresponding to the second uplink channel. The PHR parameter set may include at least one of a power headroom or a P-MPR.

[0123] As indicated above, Figure 8 are provided as examples. Other examples can be found in the Figure 8 Different than described.

[0124] Fig. 9 is a diagram illustrating an example 900 of a MAC CE with two PHRs according to the present disclosure. Example 900 is combined with Figure 6 The described aspects relate to the case where a single PHR may be included in the MAC CE to report power headroom information associated with two simultaneously transmitted channels.

[0125] As shown, the MAC CE may include a PHR 902 corresponding to a first uplink channel and a second uplink channel. The PHR 902 may include a power backoff indication field 904, a virtual indicator field ("V field") 906, a first MPE field 908, a second MPE field 910, and a Pcmax field 914. The first MPE field 908 may be used, for example, to report a P-MPR value associated with the first uplink channel, and the second MPE field 910 may be used to report a P-MPR value associated with the second uplink channel. A reserved field 912 may be included adjacent to the second MPE field 910, as only a single Pcmax field 914 is included. As shown, the PHR 902 may also include a PH field 916.

[0126] In some aspects, for example, the PHR 902 may indicate a power headroom value corresponding to the first uplink channel and the second uplink channel, and the power headroom value may be based on the maximum total transmit power limit. In some aspects, the power headroom value may also be based on a first set of parameter values ​​of a parameter set associated with the first uplink channel and a second set of parameter values ​​of the parameter set associated with the second uplink channel. The parameter set includes an MPR, an A-MPR, a P-MPR, or an additional power adjustment parameter ΔT C The PHR 902 may indicate a first P-MPR corresponding to the first uplink channel and a second P-MPR corresponding to the second uplink channel. The PHR may also indicate a first configured maximum output power (Pcmax) value corresponding to the first uplink channel and a second Pcmax value corresponding to the second uplink channel. In some aspects, for example, assuming that P PUSCH,b,f,c,1 (i,j,q d ,l) and P PUSCH,b,f,c,2 (i,j,q d , l) are the transmit powers of the first uplink channel and the second uplink channel respectively, then the single power headroom can be calculated as:

[0127] P PUSCH (i,j,q d ,l)=P cmax,b,f,c (i)-P PUSCH,b,f,c,1 (i,j,q d ,l)-P PUSCH,b,f,c,2 (i,j,q d ,l),

[0128] The value P cmax,b,f,c (i) is to use the MPR, A-MPR, P-MPR, ΔT associated with the two corresponding uplink channels C The configured maximum total transmit power limit is calculated using the value.

[0129] As indicated above, Fig. 9 are provided as examples. Other examples can be found in the Fig. 9 Different than described.

[0140] although Fig.10 An example block diagram of process 1000 is shown, but in some aspects, process 1000 may include Fig.10 The blocks depicted in the process 1000 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 1000. Additionally or alternatively, two or more of the blocks in the process 1000 may be executed in parallel.

[0141] Fig.11 is a diagram illustrating an example process 1100, performed, for example, by a network node, in accordance with the present disclosure. The example process 1100 is an example of operations in which a network node (eg, network node 604) performs power headroom reporting associated with simultaneous transmission on multiple uplink channels.

[0142] like Fig.11 As shown, in some aspects, process 1100 may include: sending configuration information corresponding to a power headroom report associated with simultaneous transmissions on multiple uplink channels, the configuration information indicating a maximum total transmit power limit associated with the simultaneous transmissions (block 1110).
