Description

Technical Field

[0001] The following relates generally to wireless communications and, more specifically, to multi-panel power reporting techniques. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems, which may be referred to as new radio (NR) systems. These systems may employ various technologies, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices, which may be further referred to as user equipment (UE).

[0003] A UE may communicate with a base station in a wireless communication system, for example, using one or more uplink transmissions. In some situations, conventional techniques for power management at the UE may be insufficient. For example, the UE may not accurately report the power usage of uplink transmissions, which may result in relatively poor power management or inefficient communication in the system.

[0004] Overview

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support multi-panel power reporting techniques. Generally, the described techniques provide multi-panel power headroom reporting in a wireless communication system, which can enable devices in the system to accurately indicate power capabilities, more efficiently schedule communications, or enhance power management, among other benefits. For example, a user equipment (UE) may communicate with a base station using multiple panels (e.g., a first panel and a second panel). The UE may determine one or more panel-specific power headroom values. For example, the UE may calculate a first power headroom value for the first panel. The UE may additionally or alternatively calculate a second power headroom value for the second panel. The UE may transmit a power headroom report indicating the one or more panel-specific power headroom values. In some examples, the UE may transmit the power headroom report based on identifying that one or more thresholds associated with the power headroom report are met. For example, the UE may determine that a timer associated with the power headroom report has expired, one or more power backoff metrics meet one or more thresholds, a medium access control (MAC) entity has uplink resources for uplink transmission, or any combination thereof. In some cases, a power headroom report may include one or more fields that indicate power headroom values ​​that vary from panel to panel, whether a first power headroom value for a first panel is included in the report, whether a second power headroom value for a second panel is included in the report, or any combination thereof, as well as other examples of the fields described herein.

[0027] Detailed description

[0028] Some wireless communication systems may support multi-panel communication between user equipment (UE) and a base station. As an illustrative example, a UE may use a first panel for uplink transmissions to a base station, a second panel for uplink transmissions to the base station, and so on. In some conventional systems, the UE may transmit a power headroom report (PHR) to the base station, which indicates the difference between the maximum transmit power at the UE and the currently used transmit power. However, different panels may be associated with different power usage, channel conditions, and so on. For example, a first panel of a UE may experience a maximum permitted exposure (MPE) event (e.g., a person may be within a threshold power exposure range for transmissions using the first panel), and the power of the first panel may be reduced. Conventional power headroom reporting techniques do not account for power management of multiple panels (e.g., the report may indicate the power headroom of the entire UE). Such techniques may result in relatively poor system performance. For example, the UE may not accurately report the power headroom values ​​of different panels, or the base station may not be aware of MPE events, which may lead to inefficient communication or relatively poor power management (e.g., the base station may schedule data above the power reduction threshold for the first panel, the base station may not allocate resources to the second panel, which can use more power, and so on).

[0029] According to the techniques described herein, a wireless communication system may implement multi-panel power headroom reporting for communications between devices, which may enable devices to accurately indicate power capabilities, more efficiently schedule communications, or enhance power management, among other benefits. For example, a UE may communicate with a base station using a first panel and a second panel (e.g., a first antenna panel and a second antenna panel). The UE may determine one or more panel-specific power headroom values ​​to report to the base station. For example, the UE may calculate a first power headroom value for the first panel (e.g., based on one or more panel-specific parameters, such as a maximum transmit power parameter associated with the first panel, a maximum power reduction parameter associated with the first panel, etc.). Additionally or alternatively, the UE may calculate a second power headroom value for the second panel (e.g., using one or more panel-specific parameters, such as a maximum transmit power parameter associated with the second panel, a maximum power reduction parameter associated with the second panel, etc.).

[0030] The UE may transmit a power headroom report indicating the one or more panel-specific power headroom values. In some examples, the UE may transmit the power headroom report based on identifying that one or more thresholds associated with the power headroom report are met. For example, the UE may determine that a timer associated with the power headroom report has expired, one or more power backoff metrics meet one or more thresholds (e.g., a change in the power backoff metrics for the first panel, the second panel, or both may meet a change threshold), a medium access control (MAC) entity has uplink resources for uplink transmission, or any combination thereof. The power headroom report may include one or more fields indicating the panel-specific power headroom values. For example, the UE may populate one or more fields of the report indicating whether a first power headroom value for the first panel is included in the report, whether a second power headroom value for the second panel is included in the report, whether the MAC entity applies a power management technique, whether the panel-specific power headroom value is based on an actual transmission format or a virtual transmission format, or any combination thereof, as well as other examples of fields.

[0031] Aspects of the present disclosure are initially described in the context of wireless communication systems. Aspects of the present disclosure are subsequently described in the context of resource scheduling and process flow. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to multi-panel power reporting techniques.

[0032] Figure 1 An example of a wireless communication system 100 supporting multi-panel power reporting techniques according to aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0033] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be different forms of devices or devices with different capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which UEs 115 and base stations 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support signal communication according to one or more radio access technologies.

[0034] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be different forms of devices or devices with different capabilities. Figure 1 1. The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relays, integrated access and backhaul (IAB) nodes, or other network equipment), such as Figure 1 As shown in .

[0035] Each base station 105 can communicate with the core network 130, or with each other, or both. For example, the base stations 105 can interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 can communicate with each other directly (e.g., directly between the base stations 105), indirectly (e.g., via the core network 130), or both directly and indirectly over the backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul links 120 can be or include one or more wireless links.

[0036] One or more of the base stations 105 described herein may include or may be referred to by one of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home Evolved Node B, or other suitable terminology.

[0037] UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects, such as appliances or vehicles, meters, etc.

[0038] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 As shown in .

[0039] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0040] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by a UE 115. A carrier may operate in a standalone mode in which initial acquisition and connection may be performed by a UE 115 via the carrier, or a carrier may operate in a non-standalone mode in which the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0041] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0042] A carrier may be associated with a particular bandwidth of radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) of a carrier of a particular radio access technology. Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0043] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may include one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further improve the data rate or data integrity of communications with UE 115.

[0044] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, which can be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the maximum supported subcarrier spacing, and N f The maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0045] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of code element periods (e.g., depending on the length of the cyclic prefix added before each code element period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-time slots containing one or more code elements. Excluding the cyclic prefix, each code element period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating band.

[0046] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0047] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for physical control channels may be defined by a number of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0048] In some examples, base stations 105 can be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0049] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communication, operating over a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0050] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. The UE 115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication and can be supported by one or more mission-critical services such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably herein.

[0051] In some examples, UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving base station 105.

[0052] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and the EPC or 5GC may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnects to external networks. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0053] Some network devices (such as base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., base station 105).

[0054] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or the decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter long. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can penetrate various structures sufficiently for macrocells to provide service to UEs 115 located indoors. Transmissions using UHF waves can be associated with smaller antennas and a shorter range (e.g., less than 100 kilometers) compared to transmissions using the lower frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0055] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band, such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) may employ carrier sensing for conflict detection and avoidance. In some examples, operations in the unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in the licensed band. Operations in the unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0056] The base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having several rows and columns of antenna ports that the base station 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0057] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0058] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly to communicate on the logical channel. The MAC layer can perform priority handling and multiplex logical channels into transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission of the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration and maintenance of the RRC connection of the radio bearer that supports user plane data between the UE 115 and the base station 105 or the core network 130. In the physical layer, the transport channel can be mapped to the physical channel.

[0059] In some examples, the wireless communication system 100 can support multi-panel communications between the UE 115 and the base station 105. As an illustrative example, the UE can use a first panel to communicate with a first TRP associated with the base station 105, use a second panel to communicate with a second TRP associated with the base station 105, etc. In some examples, different panels of the UE 115 can be associated with different parameters (e.g., power parameters), conditions (e.g., one or more panels can experience an MPE event), etc.

[0060] According to the techniques described herein, the wireless communication system 100 can implement multi-panel power headroom reporting for communications between devices, which can enable devices to accurately indicate power capabilities, more efficiently schedule communications, or enhance power management, among other benefits. For example, a UE 115 can communicate with a base station 105 using a first panel and a second panel (e.g., a first antenna panel and a second antenna panel). The UE 115 can determine one or more panel-specific power headroom values ​​to report to the base station 105. For example, the UE 115 can calculate a first power headroom value for the first panel (e.g., based on one or more panel-specific parameters, such as a maximum transmit power parameter associated with the first panel, a maximum power reduction parameter associated with the first panel, etc.). Additionally or alternatively, the UE 115 can calculate a second power headroom value for the second panel (e.g., using one or more panel-specific parameters, such as a maximum transmit power parameter associated with the second panel, a maximum power reduction parameter associated with the second panel, etc.).

[0061] The UE 115 may transmit a power headroom report indicating the one or more panel-specific power headroom values. In some examples, the UE 115 may transmit the power headroom report based on identifying that one or more thresholds associated with the power headroom report are met. For example, the UE 115 may determine that a timer associated with the power headroom report has expired, one or more power backoff metrics meet one or more thresholds (e.g., a change in the power backoff metrics for the first panel, the second panel, or both may meet a change threshold), a medium access control (MAC) entity has uplink resources for uplink transmission, or any combination thereof. The power headroom report may include one or more fields indicating the panel-specific power headroom values. For example, the UE 115 may populate one or more fields of the report indicating whether a first power headroom value for the first panel is included in the report, whether a second power headroom value for the second panel is included in the report, whether the MAC entity applies a power management technique, whether the panel-specific power headroom value is based on an actual transmission format or a virtual transmission format, or any combination thereof, as well as other examples of fields.

[0062] Figure 2 An example of a wireless communication system 200 that supports multi-panel power reporting techniques according to aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. For example, the wireless communication system 200 can include a UE 115-a and a base station 105-a, which can be as described with reference to FIG. Figure 1 Examples of UE 115 and base station 105 are described.

[0063] The wireless communication system 200 may support multi-panel communications 205 between a UE 115-a and a base station 105-a in a geographic area 110-a. As illustrative examples, the UE 115-a may send an uplink transmission to the base station 105-a using a first panel (e.g., a first antenna set of the first panel), send an uplink transmission to the base station 105-a using a second panel (e.g., a second antenna set of the second panel), or both.

[0064] In some examples, UE 115-a may implement power management techniques (e.g., power control for uplink transmissions, such as physical uplink shared channel transmissions using one or more panels). For example, UE 115-a may transmit a report 210 to base station 105-a indicating a power headroom value of UE 115-a.

[0065] For example, UE 115-a may determine the power headroom as the difference between the maximum transmit power of UE 115-a and the transmit power of UE 115-a (e.g., currently used transmit power, predicted transmit power, etc.).

[0066] In some examples, UE 115-a may calculate the transmit power of UE 115-a. For example, UE 115-a may calculate the actual transmit power based on one or more configuration values ​​(e.g., configured by base station 105-a, preconfigured at UE 115-a, or a combination thereof), resource assignments from base station 105-a, and other examples of factors used to calculate transmit power. As an illustrative example, UE 115-a may calculate the actual transmit power "P" using Equation 1. PUSCH (i, j, q d , l)”:

[0067]

[0068] In formula 1, may represent a target signal-to-noise ratio (SINR) (e.g., set by the configured P0 value of UE 115-a), may represent the bandwidth of a physical uplink shared channel (PUSCH) resource assignment (e.g., in terms of a number of resource blocks for a scheduled PUSCH transmission), α b，f，c， (j) can represent the path loss compensation factor, PL b，f，c (q d ) may represent a path loss reference (eg, which may be referred to as “RS”), Δ TF，b，f，c (i) may represent adjustments related to the modulation and coding scheme (MCS) (e.g., the power may depend on the MCS scheme associated with the PUSCH transmission), and f b，f，c(i, l) may represent the PUSCH power control adjustment state. In some examples, various factors used to calculate the actual transmit power may be configured at UE 115-a (e.g., via RRC signaling, pre-configured values ​​at UE 115-a, etc.), or UE 115-a may determine these factors in other ways (e.g., based on control information from base station 105-a or other determination methods). For example, parameters i, j, q d , l can be a default parameter, or can be a signaled parameter, or a combination thereof.

[0069] In some examples, UE 115-a may configure the UE 115-a to use the value of i, j, q based on one or more configuration values ​​(e.g., configured to use the value of i, j, q d As an illustrative example, UE 115-a may use Equation 2 to calculate the virtual transmit power “P PUSCH (i, j, q d , l)”:

[0070]

[0071] In some examples, the maximum transmit power (e.g., the configured UE maximum output power PCMAX for carrier “f” serving cell “c”) f，c ) can be set so that the corresponding measurement meets the threshold. For example, the maximum transmit power can be set so that the measured peak value of the effective isotropic radiated power (EIRP) (for example, which can be called "PUMAX, f，c ”) is within the scope of the explanation in Equation 3:

[0072]

[0073] In some examples, the various factors used for Equation 3 may be configured at UE 115-a (e.g., via RRC signaling, pre-configured values ​​at UE 115-a, etc.), or UE 115-a may otherwise determine these factors (e.g., based on control information from base station 105-a or other determination methods). f，c In some examples, P-MPR may represent the maximum output power reduction allowed at UE 115-a. f，c May be referred to as the power management maximum power reduction parameter.

[0074] In some examples, for one or more scenarios, UE 115-a may apply a maximum output power reduction for carrier f of serving cell c. For example, UE 115-a may apply the maximum output power reduction to ensure compliance with applicable electromagnetic power density exposure thresholds, to address unwanted emissions in situations where multiple radio access technologies are transmitting simultaneously, to address self-protection requirements, to ensure compliance with applicable electromagnetic power density exposure thresholds in situations where proximity detection is used to address such thresholds that may result in lower maximum output power, or any combination thereof.

[0075] In some examples, UE 115-a may report one or more parameters (e.g., available maximum output transmit power) to base station 105-a in report 210. Base station 105-a may perform scheduling based on report 210. For example, in addition to other examples of scheduling decisions, base station 105-a may allocate resources to UE 115-a based on report 210 (e.g., if report 210 includes a power headroom with a positive value, indicating that UE 115-a can use more power and transmit more data, base station 105-a may increase resources and associated data rates, if report 210 includes a power headroom with a negative value, indicating that UE 115-a is using more than a threshold amount of power, base station 105-a may reduce resources and associated data rates, and so on). Additionally or alternatively, base station 105-e may transmit a signal indicating power adjustments for one or more panels based on the report. In some examples, parameters (e.g., P-MPR f，c and maxUplinkDutyCycle-FR2 (maximum uplink duty cycle-FR2) parameters) can affect the maximum uplink performance of the selected uplink transmission path.

[0076] In some examples, the wireless communication system 200 may support multi-panel power headroom indication. For example, report 210 may be an example of a multi-panel power headroom report (e.g., report 210 may indicate a power headroom value for a first panel of carrier f serving cell c, report 210 may indicate a power headroom value for a second panel of carrier f serving cell c, etc.). Such reports 210 may enable devices of the memory system 200 to accurately indicate power capabilities, more efficiently schedule communications, or enhance power management, among other benefits. For example, a UE 115-a may communicate with a base station 105 using a first panel and a second panel (e.g., a first antenna panel and a second antenna panel). The UE 115-a may determine one or more panel-specific power headroom values ​​to report to the base station 105-a. For example, the UE 115-a may calculate a first power headroom value for a first panel (e.g., based on one or more panel-specific parameters, such as a maximum transmit power parameter associated with the first panel, a maximum power reduction parameter associated with the first panel, etc.). Additionally or alternatively, UE 115-a may calculate a second power headroom value for the second panel (e.g., using one or more panel-specific parameters, such as a maximum transmit power parameter associated with the second panel, a maximum power reduction parameter associated with the second panel, etc.).

[0077] The UE 115-a may transmit a power headroom report 210 indicating the one or more panel-specific power headroom values. In some examples, the UE 115-a may transmit the power headroom report 210 based on identifying that one or more thresholds associated with the power headroom report 210 are satisfied. For example, the UE 115-a may determine that a timer associated with the power headroom report 210 has expired, one or more power backoff metrics satisfy one or more thresholds (e.g., a change in the power backoff metrics for the first panel, the second panel, or both may satisfy a change threshold), the MAC entity has uplink resources for uplink transmission, or any combination thereof. The power headroom report 210 may include one or more fields indicating the panel-specific power headroom value. For example, UE 115-a may populate one or more fields of report 210 that indicate whether a first power headroom value for a first panel is included in the report 210, whether a second power headroom value for a second panel is included in the report 210, whether the MAC entity applies power management techniques, whether the panel-specific power headroom values ​​are based on an actual transport format or a virtual transport format, or any combination thereof, as well as other examples of fields of report 210.

[0078] Figure 3 Examples of resource schemes 300, 301, and 302 supporting multi-panel power reporting techniques according to aspects of the present disclosure are illustrated. In some examples, Figure 3 Various resource schemes in the wireless communication system 100 or 200 can implement various aspects. For example, resource schemes 300, 301 and 302 can illustrate an example of multi-panel communication between UE 115 and base station 105, as shown in FIG. Figure 1 and Figure 2 described.

[0079] For example, various resource schemes may include a first resource 305 and a second resource 310. The first resource 305 may be an example of an uplink resource associated with a first panel (e.g., a PUSCH resource for uplink transmission via the first panel). As an illustrative example, the first resource may correspond to a first parameter set (e.g., indicated by downlink control information (DCI) associated with a resource assignment). The first parameter set may include one or more of a first transmitted precoding matrix index (TPMI), a first sounding reference signal (SRS) resource indicator (SRI), a first uplink tag control information (TCI), or any combination thereof, as well as other examples of parameters associated with a panel. The second resource 310 may be an example of an uplink resource associated with a second panel (e.g., a PUSCH resource for uplink transmission from the second panel). The second resource 310 may correspond to a second parameter set (e.g., indicated by a DCI associated with a resource assignment). In addition to other examples of parameters associated with a panel, the second parameter set may also include one or more of a second TMPI, a second SRI, a second uplink TCI, or any combination thereof. In some examples, the base station may indicate the first resource 305 and / or the second resource 310 via a resource assignment (e.g., a signal indicating uplink resources for communicating via the panel).

[0080] Resource scheme 300 may illustrate an example of spatial division multiplexing (SDM) for communicating using multiple panels. As an illustrative example, a UE may transmit one or more uplink transmissions using a first panel and a second panel in accordance with SDM communication. First resources 305 and second resources 310 may utilize overlapping resources in time and frequency (e.g., the same time-frequency resources), but transmit on different spatial beams (e.g., a first panel may use a first focused signal beam in a first spatial configuration, while a second panel may use a different second focused signal beam in a second spatial configuration).

[0081] Resource scheme 301 may illustrate an example of FDM for communicating using multiple panels. As an illustrative example, a UE may transmit one or more uplink transmissions using a first panel and a second panel in accordance with FDM communication. First resource 305 and second resource 310 may utilize overlapping resources in time (e.g., the same time resource), but may be transmitted on different frequencies (e.g., first resource 305 may be allocated to a first frequency for a time period, while second resource 320 may be allocated to a second frequency for a time period).

[0082] Resource scheme 302 may illustrate an example of TDM for communicating using multiple panels. As an illustrative example, a UE may transmit one or more uplink transmissions using a first panel and a second panel according to TDM communication. First resource 305 and second resource 310 may utilize overlapping resources in frequency (e.g., the same frequency band resources), but may be transmitted at different times (e.g., first resource 305 may be allocated to a first time period of a first frequency, while second resource 310 may be allocated to a second time period of the first frequency).

[0083] According to the techniques described herein, resource schemes 300, 301, and / or 302 may enable multi-panel power headroom reporting for communications between devices, which may enable devices to accurately indicate power capabilities, more efficiently schedule communications, or enhance power management, among other benefits. For example, UE 115 may communicate with base station 105 using a first panel and a second panel (e.g., a first antenna panel and a second antenna panel) according to SDM, FDM, TDM, or any combination thereof. UE 115 may determine one or more panel-specific power headroom values ​​to report to base station 105. For example, UE 115 may calculate a first power headroom value for a first panel (e.g., based on one or more panel-specific parameters, such as a maximum transmit power parameter associated with the first panel, a maximum power reduction parameter associated with the first panel, etc.). Additionally or alternatively, UE 115 may calculate a second power headroom value for a second panel (e.g., using one or more panel-specific parameters, such as a maximum transmit power parameter associated with the second panel, a maximum power reduction parameter associated with the second panel, etc.).

[0084] The UE 115 may transmit a power headroom report indicating the one or more panel-specific power headroom values. In some examples, the UE 115 may transmit the power headroom report based on identifying that one or more thresholds associated with the power headroom report are met. For example, the UE 115 may determine that a timer associated with the power headroom report has expired, one or more power backoff metrics meet one or more thresholds (e.g., a change in the power backoff metrics for the first panel, the second panel, or both may meet a change threshold), a medium access control (MAC) entity has uplink resources for uplink transmission, or any combination thereof. The power headroom report may include one or more fields indicating the panel-specific power headroom values. For example, the UE 115 may populate one or more fields of the report indicating whether a first power headroom value for the first panel is included in the report, whether a second power headroom value for the second panel is included in the report, whether the MAC entity applies a power management technique, whether the panel-specific power headroom value is based on an actual transmission format or a virtual transmission format, or any combination thereof, as well as other examples of fields.

[0085] Figure 4 Examples of wireless communication systems 400, 401, and 402 supporting multi-panel power reporting techniques according to aspects of the present disclosure are illustrated. In some examples, Figure 4 Various example wireless communication systems may implement aspects of wireless communication systems 100 and 200. For example, wireless communication systems 400, 401, and 402 may include UE 115 and base station 105, which may be reference systems. Figure 1 and Figure 2 Examples of corresponding devices are described.

[0086] The wireless communication system 400 may illustrate an example of communication between a UE 115-b and a base station 105-b in a geographic area 110-b. The UE 115-b and the base station 105-b may communicate using a beam 415-a (e.g., one or more beams 415-a associated with a panel of the UE 115-b). For example, the UE 115-b may send an uplink transmission 405-a using the beam 415-a and may receive a downlink transmission 410-a from the base station 105-b (e.g., using a receive beam of the first panel used to transmit the uplink transmission 405-a).

[0087] The wireless communication system 401 may illustrate an example of communication between a UE 115-c and a base station 105-c in a geographic area 110-c. In general, the wireless communication system 401 may illustrate an example of an MPE event. For example, a person 420-a (or other object / condition) may be in a proximity and / or orientation that satisfies a threshold. As an illustrative example, the person 420-a may be positioned such that an uplink transmission 405-b using a configured power may exceed a threshold power exposure for the person 420-a. To ensure that the MPE threshold for the person 420-a is met, the UE 115-c may be configured to reduce the power of the uplink transmission 405-b (e.g., the UE 115-b may reduce the power of a first panel associated with the transmit beam 415-b). In some examples, because the distance between the base station 105-c and the person 420-a, the frequency of the downlink transmission 410-b, or both, satisfies the MPE threshold, the base station 105-c may continue to transmit the downlink transmission 410-b. However, such MPE events may result in relatively inefficient or unreliable communications.

[0088] The wireless communication system 402 may illustrate an example of a method for maintaining communication with the base station 105-d during an MPE event. For example, the UE 115-d may continue to receive downlink transmissions 410-c from the base station 105-d using beam 415-c. Additionally or alternatively, the UE 115-d may use a second panel to communicate uplink transmissions 405-c to the base station 105-d. For example, the UE 115-d may include a second panel that does not experience the MPE event (e.g., transmissions using beam 415-d may meet the threshold power exposure for the person 420-b, but uplink transmissions using beam 415-c may not meet the threshold, and the UE 115-d may reduce the power of the first panel used for the uplink transmission, as described above). UE 115-d may switch from communicating with the first panel to communicating with the second panel in response to the MPE event (e.g., UE 115-d may switch from beam 415-c to beam 415-d to meet the power exposure threshold of uplink transmission 405-c). In other words, downlink communication 410-c may be maintained and uplink transmission 405-c may be changed. In some examples, UE 115-d may receive downlink transmission 410-c from a first TRP of base station 150-d and communicate uplink transmission 405-c with node 425 (e.g., a second TRP of base station 150-d). Additionally or alternatively, the node may be an example of another base station 105 in addition to other examples of a wireless node. In some other examples, UE 115-d may send uplink transmission 405-c to the first TRP of base station 105-d using second beam 415-d.

[0089] However, in some examples, the power reporting technique may be relatively inefficient. For example, UE 115-d may report the power headroom of UE 115-d, but may not be able to report multi-panel power headroom values. In such examples, UE 115-d may not accurately report the power headroom values ​​of different panels, or base station 105-d may not be aware of the MPE event, which may result in inefficient communication or relatively poor power management. For example, base station 105-d may schedule uplink resources for which the power of the desired uplink transmission 405 is above the power threshold for reducing power of the first panel (e.g., in response to the MPE event), base station 105-d may not allocate resources to a second panel that is capable of using more power for uplink transmission 405-c (e.g., resulting in inefficient communication), and other examples.

[0090] According to the techniques described herein, wireless communication systems 400, 401, and / or 402 can implement multi-panel power headroom reporting for communications between devices, which can enable devices to accurately indicate power capabilities, more efficiently schedule communications, or enhance power management, among other benefits. For example, a UE 115 can communicate with a base station 105 using a first panel and a second panel (e.g., a first antenna panel and a second antenna panel) according to SDM, FDM, TDM, or any combination thereof. The UE 115 can determine one or more panel-specific power headroom values ​​to report to the base station 105. For example, the UE 115 can calculate a first power headroom value for the first panel (e.g., based on one or more panel-specific parameters, such as a maximum transmit power parameter associated with the first panel, a maximum power reduction parameter associated with the first panel, etc.). Additionally or alternatively, the UE 115 can calculate a second power headroom value for the second panel (e.g., using one or more panel-specific parameters, such as a maximum transmit power parameter associated with the second panel, a maximum power reduction parameter associated with the second panel, etc.).

[0091] The UE 115 may transmit a power headroom report indicating the one or more panel-specific power headroom values. In some examples, the UE 115 may transmit the power headroom report based on identifying that one or more thresholds associated with the power headroom report are met. For example, the UE 115 may determine that a timer associated with the power headroom report has expired, one or more power backoff metrics meet one or more thresholds (e.g., a change in the power backoff metrics for the first panel, the second panel, or both may meet a change threshold), a medium access control (MAC) entity has uplink resources for uplink transmission, or any combination thereof. The power headroom report may include one or more fields indicating the panel-specific power headroom values. For example, the UE 115 may populate one or more fields of the report indicating whether a first power headroom value for the first panel is included in the report, whether a second power headroom value for the second panel is included in the report, whether the MAC entity applies a power management technique, whether the panel-specific power headroom value is based on an actual transmission format or a virtual transmission format, or any combination thereof, as well as other examples of fields.

[0092] Figure 5 An example of a process flow 500 for supporting multi-panel power reporting techniques according to aspects of the present disclosure is illustrated. In some examples, the process flow 500 can implement aspects of wireless communication systems 100, 200, 400, 401, 402, or any combination thereof. For example, the process flow 500 can illustrate operations performed by a UE 115-e or a base station 105-e, which can be examples of respective devices described herein. In some examples, the process flow 500 can illustrate implementation of multi-panel power headroom reporting for multi-panel communication between a UE 115-e and a base station 105-e.

[0093] In some examples, the base station 105-e may transmit control signaling to the UE 115-e at 505. For example, the base station 105-e may send a DCI indicating one or more resource assignments for communicating with the UE 115-e (e.g., the DCI may indicate first resources for uplink transmissions from the UE 115-e using a first panel, second resources for uplink transmissions from the UE 115-e using a second panel).

[0094] At 510, the UE 115-e and the base station 105-e may communicate. In some examples, the UE 115-e and the base station 105-e may communicate using multi-panel communication as described herein, e.g., with reference to Figure 1-4As an illustrative example, the UE 115-e may send one or more uplink transmissions using one or more panels of the UE 115-e (eg, a first panel and a second panel associated with communications on a carrier).

[0095] In some examples, at 515, the UE 115-e may determine that one or more thresholds are met (e.g., the UE 115-e may identify one or more triggers for transmitting a multi-panel power headroom report). For example, the UE 115-e may determine that a timer associated with the power headroom report has expired (e.g., the UE 115-e may determine that the timer phr-ProhibitTimer has expired and may transmit the report based on the expiration).

[0096] Additionally or alternatively, the UE 115-e may determine that one or more power backoff metrics satisfy one or more thresholds. As an illustrative example, the UE 115-e may include two panels (e.g., a first panel corresponding to a k value of 0 and a second panel corresponding to a k value of 1) and may communicate with the base station 105-e using the two panels at 510. For example, if a change in a power backoff metric associated with the first panel, the second panel, or at least one of the first and second panels satisfies a threshold, the UE 115-e may determine that a power headroom report has been triggered. For example, the UE 115-e may determine that either a power backoff associated with the first panel (e.g., a power management maximum power reduction parameter of the first panel, which may be referred to as P-MPR(1)) or a power backoff associated with the second panel (e.g., a power management maximum power reduction parameter of the second panel, which may be referred to as P-MPR(2)) satisfies a threshold. Additionally or alternatively, the UE 115-e may determine that both a power backoff associated with the first panel and a power backoff associated with the second panel satisfy a threshold. Additionally or alternatively, the UE 115 - e may determine that a sum of the power backoffs of the first panel and the second panel satisfies a threshold.

[0097] As an illustrative example, the UE 115-e may report a multi-panel power headroom report based on one or more satisfied thresholds. For example, the power headroom report may be triggered based on detecting that a timer has expired (e.g., phr-ProhibitTimer has expired), detecting that a MAC entity has uplink resources for a new transmission from the UE 115-e, detecting that there are uplink resources allocated for transmission on a serving cell associated with the first panel and the second panel or that there is a physical uplink control channel (PUCCH) transmission, and detecting a power backoff of a cell (e.g., due to power management, as described herein with reference to FIG. 1 ) when the MAC entity has uplink resources allocated for transmission on the cell or a PUCCH transmission. Figure 2 in question) has changed by more than a threshold associated with the power headroom report (e.g., phr-Tx-PowerFactorChange dB) since the last transmission of the power headroom report, or any combination thereof.

[0098] At 520, the UE 115-e may determine one or more power headroom values, for example, based on determining that the one or more thresholds are satisfied. For example, as described herein, the UE 115-e may support per-panel power headroom calculations at the UE 115-e. The UE 115-e may calculate a first power headroom value for a first panel, a second power headroom value for a second panel, or both (e.g., and other panel number examples). As an illustrative example, the UE 115-e may calculate a panel-specific power headroom value for a PUSCH transmission using Equation 4:

[0099] PH type1，b，f，c (i, j, q d , l, k) = P CMAX，f，c (i, k)-P k，PUSCH (i, j, q d ,l) (4) In formula 1, PH type1，b，f，c (i, j, q d , l, k) may represent the type 1 power headroom value for PUSCH transmission for panel k (e.g., the first panel may correspond to panel index k of 0, the second panel may correspond to panel index k of 1, and so on). P CMAX，f，c (i, k) may represent the maximum transmit power of panel k (e.g., as configured at UE 115-e as described herein). In some examples, P CMAX，f，c (i, k) may be the same for multiple panels (eg, configured the same for each of the first panel and the second panel). In some other examples, P CMAX，f，c (i, k) can be panel specific. For example, P CMAX，f，c (i, k) may be based on the power management maximum power reduction parameter of panel k (e.g., the panel-specific P-MPR value represented by P-MPR(k) ≥ 0 may be used to calculate P CMAX，f，c (i, k)). In some examples, P k，PUSCH (i, j, q d , l) can represent the transmission power that varies from panel to panel.

[0100] In some examples, the panel-specific transmit power may be an actual transmit power (e.g., the power headroom reported value for a particular panel may be the actual transmit power), or the panel-specific transmit power may be a virtual transmit power (e.g., the power headroom reported value for a particular panel may be the actual transmit power). As an illustrative example, the UE 115 - e may calculate the panel-specific transmit power (e.g., for panel k) as the actual transmit power using Equation 5:

[0101]

[0102] In formula 5, may represent a target signal-to-noise ratio (SINR) (e.g., set by the configured P0 value of UE 115-a), may represent the bandwidth of the PUSCH resource assignment (e.g., in terms of a number of resource blocks for scheduled PUSCH transmissions), α k，b，f，c， (j) can represent the path loss compensation factor, PL k，b，f，c (q d ) may represent a path loss reference (eg, which may be referred to as “RS”), Δ k，TF，b，f，c (i) may represent an MCS-related adjustment (eg, the power may depend on the MCS scheme associated with the PUSCH transmission), and f k，b，f，c (i, l) may represent the PUSCH power control adjustment state. In some examples, various factors used to calculate the actual transmit power may be configured at the UE 115-e (e.g., via RRC signaling, pre-configured values ​​at the UE 115-e, etc.), or the UE 115-e may determine these factors in other ways (e.g., based on control information from the base station 105-e or other determination methods). For example, the parameters i, j, q d , l can be a default parameter, or can be a signaled parameter, or a combination thereof. In some examples, the various parameters in Equation 5 can be panel-specific parameters (e.g., each panel k can correspond to an associated set of parameters for calculating transmit power), can be common to multiple panels, or any combination thereof.

[0103] In some examples, UE 115-e may be configured to use i, j, q based on one or more configuration values ​​(e.g., d , one or more default parameters of the value of l) to calculate the virtual transmit power that varies from panel to panel. As an illustrative example, UE115-a can use Equation 6 to calculate the virtual transmit power "P k，PUSCH (i, j, q d , l)”:

[0104]

[0105] At 525, the UE 115-e may generate a report. For example, at 520, the UE 115-e may populate one or more fields of the report based at least in part on determining the power headroom value. The report may be an example of a multi-panel power headroom report as described herein. For example, the report may include at least one of a first power headroom value for a first panel of the UE 115-e or a second power headroom value for a second panel of the UE 115-e. In some examples, the one or more fields may indicate whether the first power headroom value for the first panel is included in the report, whether the second power headroom value for the second panel is included in the report, whether the MAC entity applies a power management technique, whether the panel-specific power headroom value is based on an actual transmission format or a virtual transmission format, or any combination thereof, as well as other examples of fields. As an illustrative example, the UE 115-e may populate the report as shown in Table 1 below. For example, Table 1 may illustrate an example report format for a multi-panel power headroom report, where each component carrier is associated with the report (e.g., including two power headroom values, as well as other examples of the number of panel-specific power headroom values).

[0106]

[0107] Table 1

[0108] In Table 1, the P1 field may indicate whether a power headroom report (e.g., a power headroom value) is reported for the first panel. The P2 field may indicate whether a power headroom report (e.g., a power headroom value) is reported for the second panel. The P field may indicate whether the MAC entity applies power backoff due to power management (e.g., whether P-MPR is implemented, the value of P-MPR, or both). The V field may indicate whether the power headroom value is based on the actual transport format or the virtual transport reference format. In some examples, the V field may be set to 0, indicating that the actual transport format and the associated P for panel k are included. CMAX，f，c The presence of an octet of the field, or the V field may be set to 1, indicates a virtual transport reference format and the inclusion of the associated P CMAX，f，c In some examples, the Power Headroom Value field can indicate the power headroom value of panel k, the type of power headroom value (eg, Type 1, Type 2, Type 3, etc.), or any combination thereof.

[0109] At 530, the UE 115-e may transmit the report to the base station 105-e. In some examples, at 535, the base station 105-e may schedule resources based on the received report as described herein. For example, the base station 105-e may schedule subsequent communications with the first panel based on the power headroom value of the first panel indicated by the report, schedule communications with the second panel based on the power headroom value of the second panel indicated by the report, or both, as described herein with at least reference to Figure 1-4 described.
