Description

Technical Field

[0001] The following relates to wireless communications, including transmit power prioritization for multi-panel uplink transmissions. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (e.g., long term evolution (LTE) systems, improved 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 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 for multiple communication devices (which may also be referred to as user equipment (UE)). Summary of the Invention

[0003] The described techniques relate to improved methods, systems, devices, and apparatuses that support transmit power prioritization for multi-panel uplink transmissions. In summary, the described techniques provide for allocating available transmit power to a user equipment (UE) using prioritization considerations on a per-transmit panel basis. For example, a UE and its associated base station may determine that the UE is to use two or more transmit panels of the UE (e.g., a first transmit panel, a second transmit panel, etc.) to perform a multi-panel uplink transmission. The UE and the associated base station may identify a priority order for uplink transmissions for performing the multi-panel uplink transmission, wherein the UE's transmit panels have a corresponding priority level configured for each panel. The UE and the associated base station may also identify or otherwise determine available transmit power for the multi-panel uplink transmission and perform the transmission based on the priority order and the available transmit power. For example, the UE may use a first transmit panel at a first transmit power and a second transmit panel at a second transmit power, the first transmit power and the second transmit power being based on the available transmit power for the multi-panel uplink transmission. Thus, when allocating available transmit power for a multi-panel uplink transmission from the UE to the base station, the UE and the associated base station may enable per-transmit panel prioritization considerations.

[0055] A user equipment (UE) may support multi-panel uplink transmission to a base station using one or more transmit panels of the UE. In general, a transmit panel of a UE may refer to any configuration of hardware (e.g., antennas) and / or software (e.g., beamforming techniques, directional transmission techniques, weighting criteria, etc.) used to perform uplink transmission. For example, a transmit panel may refer to a specific transmit precoding matrix indicator (TPMI) configured for the UE, a sounding reference signal (SRS) resource indicator (SRI) configured for the UE, a transmission configuration indicator (TCI) configured for the UE, etc. In some examples, a transmit panel of the UE may refer to different antennas of the UE and / or antennas of the UE that transmit using different configurations. In some examples, two or more transmit panels of the UE are used to perform multi-panel uplink transmission using various multiplexing techniques (such as spatial division multiplexing (SDM), frequency division multiplexing (FDM), time division multiplexing (TDM), etc.). In this example, a transmit panel of the UE may refer to a transmit panel used to perform uplink transmission on a specific spatial configuration of SDM, on a specific frequency of FDM, at a specific time of TDM, etc.

[0056] In addition, the UE is typically configured with various priority orders for uplink transmissions based on the transmission type used for the uplink transmission (e.g., physical random access channel (PRACH) transmission, physical uplink control channel (PUCCH) transmission, physical uplink shared channel (PUSCH) transmission, etc.). In some examples, the transmission type may also refer to the type of information being transmitted, such as a hybrid automatic repeat request / acknowledgement (HARQ-ACK) transmission, a scheduling request (SR) transmission, a long-range radar (LRR) transmission, etc. For multi-panel uplink transmissions, the UE is also configured with an available transmit power, which defines the total amount of transmit power that the UE is allowed to use during the multi-panel uplink transmission and / or during a given time period. Therefore, when performing a multi-panel uplink transmission, the UE allocates its available transmit power based on the transmission type of the uplink transmission according to the priority order. However, these techniques do not enable or otherwise allow the UE to consider the transmitting panel when allocating available transmit power for uplink transmissions.

[0057] Various aspects of the present disclosure are first described in the context of a wireless communication system. In summary, the described techniques provide for allocating available transmit power to a UE using prioritization considerations on a per-transmit panel basis. For example, a UE and its associated base station may determine that the UE will use two or more transmit panels of the UE (e.g., a first transmit panel, a second transmit panel, etc.) to perform a multi-panel uplink transmission. The UE and the associated base station may identify a priority order for uplink transmissions for performing the multi-panel uplink transmission, wherein the UE's transmit panels have corresponding priority levels configured for each panel. The UE and the associated base station may also identify or otherwise determine available transmit power for the multi-panel uplink transmission and perform the transmission based on the priority order and the available transmit power. For example, the UE may use a first transmit panel at a first transmit power and a second transmit panel at a second transmit power, the first transmit power and the second transmit power being based on the available transmit power for the multi-panel uplink transmission. Thus, when allocating available transmit power for a multi-panel uplink transmission from the UE to the base station, the UE and the associated base station may enable per-transmit panel prioritization considerations.

[0058] Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams relating to transmit power prioritization for multi-panel uplink transmissions.

[0059] Figure 1 An example of a wireless communication system 100 that supports transmit power prioritization for multi-panel uplink transmissions in accordance with aspects of the present disclosure is shown. 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 communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices, or any combination thereof.

[0060] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be devices of varying forms or 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 areas 110 may be examples of geographic areas over which base stations 105 and UEs 115 may support transmission of signals according to one or more radio access technologies.

[0061] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Figure 1 1. Some example UEs 115 are shown in FIG. UEs 115 described herein are capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relays, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 shown.

[0062] The base stations 105 can communicate with the core network 130, or communicate with each other, or perform both operations described above. For example, the base stations 105 can be connected to 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) or indirectly (e.g., via the core network 130) on the backhaul links 120 (e.g., via X2, Xn or other interfaces), or perform both operations described above. In some examples, the backhaul links 120 can be or include one or more wireless links.

[0064] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other appropriate terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. UE 115 may also include or may 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, among other examples, which may be implemented in various items such as appliances, vehicles, meters, and other examples.

[0065] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples. Figure 1 shown.

[0066] The UE 115 and the base station 105 can communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a collection of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 can include a portion of a radio frequency spectrum band (e.g., a bandwidth part (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 can carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate operation for the carrier, user data, or other signaling. The wireless communication system 100 can support communication with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0067] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations with respect to 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 placed according to a channel grid for discovery by a UE 115. A carrier may operate in a standalone mode, where the UE 115 performs initial acquisition and connection via the carrier, or a carrier may operate in a non-standalone mode, where a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0068] 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).

[0069] 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 a number of determined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). A device of the wireless communication system 100 (e.g., a base station 105, a 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 a 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.

[0070] The signal waveform transmitted on the carrier may be composed of 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 comprise 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 coding rate of the modulation scheme, or both). Therefore, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate for the UE 115 may 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 increase the data rate or data integrity for communications with the UE 115.

[0071] One or more numerologies for a carrier may be supported, where the numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for the UE 115 may be limited to the one or more active BWPs.

[0072] The basic time unit (which may be referred to as T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can represent the maximum supported subcarrier spacing, and N f The time intervals for base station 105 or UE 115 may be expressed as multiples of a maximum supported discrete Fourier transform (DFT) size. The 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).

[0073] 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 symbol periods (e.g., depending on the length of a cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol 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 frequency band.

[0074] 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 the form of bursts of shortened TTIs (sTTIs)).

[0075] Physical channels may be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels may be multiplexed on a downlink carrier using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across the system bandwidth of a carrier or a subset of the system bandwidth. 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 a 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 at one or more aggregation levels arranged in a cascaded manner. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded 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 .

[0076] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots or other types of cells, or any combination thereof). The term "cell" can refer to a logical communication entity used to communicate with the base station 105 (e.g., on a carrier) and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifier) used to distinguish between adjacent cells. In some examples, a cell can also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors (such as the capabilities of the base station 105), the scope of such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell can be or include a building, a subset of a building, or an external space between or overlapping the geographic coverage area 110, as well as other examples.

[0077] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 115 that have a service subscription with a network provider that supports the macro cell. Small cells may be associated with lower-power base stations 105 than macro cells, and may operate in the same or different frequency bands (e.g., licensed, unlicensed) as the macro cells. Small cells may provide unrestricted access to UEs 115 that have a service subscription with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A base station 105 may support one or more cells and may also support communication over one or more cells using one or more component carriers.

[0078] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0079] 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 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0080] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, the base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately aligned in time. For asynchronous operation, the base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein can be used for either synchronous or asynchronous operation.

[0081] Some UEs 115 (e.g., MTC or IoT devices) may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that incorporate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents it to a human interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other equipment. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service billing.

[0082] Some UEs 115 may be configured to employ a mode of operation that reduces power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power conservation techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communications, when 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.

[0083] 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. 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 in this article.

[0084] In some examples, UE 115 may also be able to communicate directly with other UEs 115 over D2D communication links 135 (e.g., using a peer-to-peer (P2P) or device-to-device (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 each other UE 115 in the group. In some examples, base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving base station 105.

[0085] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, the vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units) or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0086] 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), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function unit (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 unit (UPF)) that routes packets to or interconnects to an external network. 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 transmitted 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.

[0087] Some of the network devices (e.g., 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 the 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).

[0088] 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). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features, but the waves can penetrate structures sufficiently for macro cells to provide service to UEs 115 located indoors. Transmissions on UHF waves can be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0089] The wireless communication system 100 may also operate in the super high frequency (SHF) region using frequency bands from 3 GHz to 30 GHz (also known as centimeter bands) or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as millimeter bands). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be even smaller and more closely spaced than the UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The technology disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may differ depending on the country or regulatory agency.

[0090] The wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can employ license 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) can employ carrier sensing for conflict detection and avoidance. In some examples, operations in the unlicensed band can be based on a carrier aggregation configuration in combination with component carriers operating in a licensed band (e.g., LAA). Operations in the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0091] The base station 105 or UE 115 may be equipped with multiple antennas, which may 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 (which may 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 a number of rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0092] The base station 105 or UE 115 can use MIMO communication to take advantage of multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. For example, a transmitting device may send multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are sent to multiple devices).

[0093] 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., a base station 105, a UE 115) to form or direct 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 transmitted 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 transmitted 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 the device. Adjustments associated with each of the antenna elements 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).

[0094] As part of the beamforming operation, the base station 105 or the UE 115 can use beam scanning techniques. For example, the base station 105 can use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. The base station 105 can transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. The transmissions in different beam directions can be used (e.g., by a transmitting device (such as the base station 105) or by a receiving device (such as the UE 115)) to identify the beam direction for subsequent transmission or reception by the base station 105.

[0095] Base station 105 may transmit some signals (e.g., data signals associated with a particular receiving device (e.g., UE 115)) in a single beam direction (e.g., a direction associated with the receiving device). In some examples, the beam direction associated with transmissions along the single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 having the highest signal quality or otherwise acceptable signal quality.

[0096] In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights used for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may send reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may be precoded or not precoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques to send signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to send signals in a single direction (e.g., to send data to a receiving device).

[0097] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105, a receiving device (e.g., UE 115) can try multiple reception configurations (e.g., directional listening). For example, the receiving device can try multiple reception directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receive beamforming weights applied to the signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receive beamforming weights applied to the signals received at multiple antenna elements of the antenna array (any of the above operations can be referred to as "listening" according to different reception configurations or reception directions). In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving data signals). A single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0098] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communications at 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 for transmission on logical channels. The medium access control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission at 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 an RRC connection (which supports radio bearers for user plane data) between the UE 115 and the base station 105 or the core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0099] UE 115 and base station 105 can support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood that data is correctly received on communication link 125. HARQ can include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal to noise conditions). In some examples, a device can support same-slot HARQ feedback, wherein the device can provide HARQ feedback in a particular time slot for data received in previous symbols in that time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0100] UE 115 may determine that a multi-panel uplink transmission is to be performed by UE 115, the multi-panel uplink transmission using at least a first transmit panel and a second transmit panel of UE 115. UE 115 may identify a priority order for performing uplink transmissions from UE 115 for the multi-panel uplink transmission, the priority order including priority levels associated with the first transmit panel and the second transmit panel. UE 115 may identify available transmit power for the multi-panel uplink transmission. UE 115 may perform the multi-panel uplink transmission using at least the first transmit panel at a first transmit power and the second transmit panel at a second transmit power according to the priority order, the first transmit power and the second transmit power being based at least in part on the available transmit power.

[0101] Base station 105 may determine to perform a multi-panel uplink transmission from UE 115 to the base station, the multi-panel uplink transmission using at least a first transmit panel and a second transmit panel of UE 115. Base station 105 may identify a priority order for uplink transmissions for UE 115 to use for performing the multi-panel uplink transmission from UE 115, the priority order including priority levels associated with the first transmit panel and the second transmit panel. Base station 105 may identify an available transmit power of UE 115 for the multi-panel uplink transmission. Base station 105 may receive the multi-panel uplink transmission from UE 115 using at least the first transmit panel at a first transmit power and the second transmit panel at a second transmit power according to the priority order, the first transmit power and the second transmit power being based on the available transmit power.

[0102] Figure 2 An example of a wireless communication system 200 that supports transmit power prioritization for multi-panel uplink transmissions according to aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 can include a base station 205 and a UE 210, which can be examples of corresponding devices described herein. In some aspects, the UE 210 can be configured or otherwise support multi-panel uplink transmissions to the base station 205 using at least a first transmit panel and a second transmit panel.

[0103] UE 210 may support multi-panel uplink transmission to base station 205 using one or more transmit panels of UE 210 (such as first transmit panel 215 and second transmit panel 220). Generally, a transmit panel of UE 210 may refer to a panel used to perform uplink configuration. For example, a transmit panel may refer to a specific TPMI configured for the UE, an SRI configured for the UE, a TCI configured for the UE, etc. When UE 210 supports one or more antenna panels, different types of information may be used to distinguish each antenna panel from other antenna panels. It should be noted that antenna panels or antenna panel identification (ID) may be used for illustrative purposes only, and there are other alternatives for referencing or indicating antenna panels, such as first transmit panel 215 and / or second transmit panel 220.

[0104] For example, an antenna panel may be associated with a downlink or uplink signal and channel set, and correspondingly, an antenna panel ID may be associated with a signal or channel ID set and indicated or derived by the signal or channel ID. In one example, a control resource set (CORESET) may be configured with a CORESET pool index. A first antenna panel (e.g., first transmit panel 215) may be associated with a downlink control indication (DCI) in a CORESET having a first CORESET pool index value (e.g., CORESET pool index 0), and a second antenna panel (e.g., second transmit panel 220) may be associated with a DCI in a CORESET having a second CORESET pool index value (e.g., CORESET pool index 1).

[0105] In another example, an SRS set ID or an SRS resource ID may be associated with a first antenna panel (e.g., the first transmission panel 215), and another SRS set ID or SRS resource ID may be associated with a second antenna panel (e.g., the second transmission panel 220). In addition, a beam ID or a beam group ID may be associated with the first antenna panel, and another beam ID or beam group ID may be associated with the second antenna panel. A beam may be a TCI state or spatial filter setting for downlink reception or uplink transmission, and may be spatial relationship information indicated for transmitting an uplink signal. A beam may be indicated by a reference signal (RS) such as a synchronization signal block (SSB), a channel state information (CSI) RS, or an SRS. When configuring a beam ID group, the first half of the beam ID group may be associated with the first antenna panel, and the second half of the beam ID group may be associated with the second antenna panel.

[0106] When a TCI state pair is indicated, a first TCI state ID in the pair may be associated with a first antenna panel (e.g., first transmit panel 215), and a second TCI state ID in the pair may be associated with a second panel (e.g., second transmit panel 220). The uplink transmit power control configuration may include a closed-loop index, and an uplink transmission having a first closed-loop index value (e.g., 0) may be associated with the first antenna panel, and another uplink transmission having a second closed-loop index value (e.g., 1) may be associated with the second antenna panel.

[0107] An antenna port ID or antenna port group ID may be associated with a first antenna panel (e.g., the first transmit panel 215), and another antenna port ID or antenna port group ID may be associated with a second antenna panel (e.g., the second transmit panel 220), where the antenna port may include, but is not limited to, a PUSCH antenna port, an SRS antenna port, and a phase tracking RS antenna port. A DMRS code division multiplexing (CDM) group ID may be associated with the first antenna panel, and another DMRS CDM group ID may be associated with the second antenna panel. When multiple DMRS CDM groups are indicated, the first DMRS CDM group may be associated with the first antenna panel, and the second DMRS CDM group may be associated with the second antenna panel.

[0108] A timing advance group (TAG) ID may be associated with a first antenna panel (e.g., the first transmit panel 215), and another TAG ID may be associated with a second antenna panel (e.g., the second transmit panel 220). A PUCCH resource ID or resource group ID may be associated with the first antenna panel, and another PUCCH resource ID or resource group ID may be associated with the second antenna panel. When configuring a PUCCH resource ID group, the first half of the PUCCH resource IDs may be associated with the first antenna panel, and the second half of the PUCCH resource IDs may be associated with the second antenna panel. A radio network temporary identifier (RNTI) may be associated with the first antenna panel, and another RNTI may be associated with the second antenna panel. A physical cell identifier (PCI) or synchronization signal block (SSB) set ID may be associated with the first antenna panel, and another PCI or SSB set ID may be associated with the second antenna panel. By referencing or otherwise indicating a signal or channel ID, the corresponding antenna panel ID may be referenced or indicated (e.g., implicitly signaled in a configuration signal).

[0109] In some examples, the transmit panel of UE 210 may refer to different antennas of UE 210 and / or antennas of UE 210 that transmit using different configurations. In some examples, two or more transmit panels of UE 210 (e.g., first transmit panel 215 and second transmit panel 220) used to perform multi-panel uplink transmission may use various multiplexing techniques, such as SDM, FDM, TDM, etc. In this example, the transmit panel of UE 210 may refer to a transmit panel used for uplink transmission on a specific spatial configuration for SDM, on a specific frequency for FDM, at a specific time period for TDM, etc.

[0110] UE 210 may be configured with various priority orders for uplink transmissions based on the transmission type of the uplink transmission (e.g., PRACH transmission, PUCCH transmission, PUSCH transmission, etc.) In some examples, the transmission type may also refer to the type of information being transmitted in the uplink transmission, such as HARQ-ACK transmission, SR transmission, LRR, etc.

[0111] In a non-limiting example, according to some wireless communication systems, the priority order of uplink transmissions based on transmission type may be based on a channel and a priority index. For example, a PUCCH or PUSCH may be indicated by a priority index of 0 or a priority index of 1. If no priority index is provided for a PUSCH or PUCCH, the priority index is 0. UE 210 may prioritize power allocation for transmissions with a higher priority index over transmissions with a lower priority index. When two uplink transmissions have the same priority index, UE 210 may also prioritize power allocation for transmissions with one channel over transmissions with another channel based on the channel type. For single-cell operation with two uplink carriers or for operation with carrier aggregation, if the total UE transmit power for PUSCH or PUCCH or PRACH or SRS transmissions on the serving cell in a frequency range in the corresponding transmission opportunity would exceed the configured maximum transmit power, the UE 210 allocates power (e.g., available transmit power) to the PUSCH / PUCCH / PRACH / SRS transmissions according to the following priority order (in descending order) such that the total UE transmit power for transmissions on the serving cell in the frequency range is less than or equal to the configured maximum transmit power for the frequency range in each symbol of the transmission opportunity:

[0112] -PRACH transmission on PCell

[0113] - PUCCH or PUSCH transmission with a higher priority index

[0114] - For PUCCH or PUSCH transmissions with the same priority index

[0115] o PUCCH transmission with HARQ-ACK information, and / or SR, and / or LRR, or PUSCH transmission with HARQ-ACK information

[0116] o PUCCH transmission with CSI or PUSCH transmission with CSI

[0117] o PUSCH transmission without HARQ-ACK information or CSI, and for Type 2 random access procedure,

[0118] PUSCH transmission on PCell

[0119] - SRS transmission, where aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell other than the PCell

[0120] In the case of uplink transmissions with the same priority order, and for operation with carrier aggregation, UE 210 prioritizes power allocation for transmissions on the primary cell of a primary cell group (MCG) or secondary cell group (SCG) over transmissions on secondary cells. In the case of uplink transmissions with the same priority order, and for operation with two uplink carriers, UE 210 prioritizes power allocation for transmissions on the carrier on which UE 210 is configured to send PUCCH. If PUCCH is not configured for either of the two uplink carriers, UE 210 prioritizes power allocation for transmissions on the non-supplementary uplink carrier.

[0121] For multi-panel uplink transmissions, UE 210 is also configured with an available transmit power, which may also be referred to as a configured maximum transmit power. When UE 210 is in carrier aggregation or in operation with two uplink carriers, the configured maximum transmit power may be shared among all serving cells. For example, the configured maximum transmit power may be defined in 3GPP technical specifications TS 38.101-1 and TS 38.101-2. Thus, when performing multi-panel uplink transmissions, UE 210 allocates its available transmit power based on the transmission type (e.g., channel) used for the uplink transmission in order of priority. However, these techniques may not enable UE 210 or otherwise allow UE 210 to consider the transmitting panel when allocating available transmit power for uplink transmissions.

[0122] Thus, aspects of the described techniques provide for allocating available transmit power to UE 210 using prioritization considerations on a per-transmit panel basis. For example, UE 210 and base station 205 may determine that UE 210 will perform a multi-panel uplink transmission using two or more transmit panels of UE 210 (e.g., a first transmit panel 215 and a second transmit panel 220). UE 210 and base station 205 may identify a priority order for uplink transmissions for performing the multi-panel uplink transmission, wherein the transmit panels of UE 210 have corresponding priority levels configured for each panel. UE 210 and base station 205 may also identify or otherwise determine available transmit power for the multi-panel uplink transmission and perform the transmission based on the priority order and the available transmit power. For example, UE 210 may use first transmit panel 215 at a first transmit power and second transmit panel 220 at a second transmit power, the first transmit power and the second transmit power being based on the available transmit power for the multi-panel uplink transmission and taking into account the priority order of the transmit panels of UE 120. Therefore, when allocating available transmit power for multi-panel uplink transmissions from UE 210 to base station 205, UE 210 and base station 205 may enable per-transmit panel priority considerations.

[0123] In some examples, this can include each UE transmit panel having an independently configured maximum available transmit power, wherein the UE 210 applies the priority order for multi-panel uplink transmissions discussed below. When the UE 210 is in carrier aggregation or in operation with two uplink carriers, transmissions associated with the same transmit panel can share the independently configured maximum transmit power for the UE transmit panel across all carriers. For example, the independently configured maximum transmit power can be defined in 3GPP technical specifications TS 38.101-1 and TS 38.101-2. For example, the UE 210 can receive a configuration signal indicating a first available transmit power for the first transmit panel 215 and a second available transmit power for the second transmit panel 220. The configuration signal can include RRC signaling, medium access control (MAC) control elements (CEs), downlink control information (DCI), etc. sent from the base station 205, and / or can include signaling received at lower layers of the UE 210 (e.g., at the physical layer, layer 2, etc.) from higher layers of the UE 210 (e.g., the IP layer, application layer, layer 3, etc.). In this case, at least in some aspects, the available transmit power for multi-panel uplink transmissions can be based on a first available transmit power of first transmit panel 215 and a second available transmit power of second transmit panel 220. For example, the first transmit power can be based on the first available transmit power, and the second transmit power can be based on the second available transmit power.

[0124] In an example where each UE transmit panel has an independently configured maximum available transmit power, a priority order for multi-panel uplink transmissions may be identified when separate available transmit powers are configured on a per transmit panel basis. For single-cell operation with two uplink carriers or for operation with carrier aggregation, if the total UE transmit power for PUSCH or PUCCH or PRACH or SRS transmissions associated with a UE panel (e.g., a UE transmit panel, such as the first transmit panel 215 and / or the second transmit panel 220) on a serving cell in a frequency range in a corresponding transmission opportunity would exceed the configured maximum transmit power for the UE panel, the UE 210 allocates power to the PUSCH / PUCCH / PRACH / SRS transmissions associated with the UE panel according to the following priority order (in descending order) such that the total UE transmit power for transmissions associated with the UE panel on a serving cell in the frequency range is less than or equal to the configured maximum transmit power associated with the UE for the frequency range in each symbol of the transmission opportunity. The following priority order may be applied separately for each UE transmit panel according to the corresponding independently configured maximum available transmit power for the UE transmit panel:

[0125] -PRACH transmission on PCell

[0126] - PUCCH or PUSCH transmission with a higher priority index

[0127] - For PUCCH or PUSCH transmissions with the same priority index

[0128] o PUCCH transmission with HARQ-ACK information, and / or SR, and / or LRR, or PUSCH transmission with HARQ-ACK information

[0129] o PUCCH transmission with CSI or PUSCH transmission with CSI

[0130] o PUSCH transmission without HARQ-ACK information or CSI, and for Type 2 random access procedure,

[0131] PUSCH transmission on PCell

[0132] - SRS transmission, where aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell other than the PCell

[0133] In some examples, this can include two UE transmit panels (e.g., first transmit panel 215 and second transmit panel 220) sharing a configured maximum available transmit power. When UE 210 is in carrier aggregation or in operation with two uplink carriers, transmissions associated with all transmit panels can share the configured maximum transmit power across all carriers. For example, the configured maximum transmit power can be defined in 3GPP technical specifications TS 38.101-1 and TS 38.101-2. For example, UE 210 can receive a configuration signal indicating a shared available transmit power, where the shared available transmit power corresponds to the available transmit power for multi-panel uplink transmissions. The configuration signal can include RRC signaling, MAC CE, DCI, etc. sent from base station 205, and / or can include signaling received at lower layers of UE 210 from higher layers of UE 210.

[0134] In some aspects of this example, the priority order for multi-panel uplink transmissions may correspond to transmit panel > priority index > channel. For example, UE 210 may prioritize power allocation for transmissions on one transmit panel over transmissions on another transmit panel. For example, when performing multi-panel uplink transmissions, UE 210 may transmit a first uplink transmission on a first transmit panel 215 using a first transmit power, and a second uplink transmission on a second transmit panel 220 using a second transmit power. In this case, the transmit panels of UE 210 may have different priority levels. For example, UE 210 may identify or otherwise determine that the first priority of the first transmit panel 215 is a higher priority than the second priority of the second transmit panel 220, or vice versa. Consequently, UE 210 may transmit an uplink transmission on the first transmit panel 215 according to the first priority, and transmit an uplink transmission on the second transmit panel 220 according to the second priority. For example, the transmit power allocation for each transmit panel may be performed based on the corresponding priority of the transmit panel. When two uplink transmissions are associated with the same transmit panel, UE 210 may also prioritize power allocation for the transmission with a higher priority index over a transmission with a lower priority index. When two uplink transmissions are associated with the same panel and the same priority index, UE 210 may also prioritize power allocation for transmissions on one channel over transmissions on another channel.

[0135] In some aspects, the priority order consisting of transmit panel > priority index > channel can be based on an index or other identifier (ID) of the transmit panel of the UE 210. For example, the UE 210 can identify a first identifier (e.g., a first panel ID) for the first transmit panel 215 and a second identifier (e.g., a second panel ID) for the second transmit panel 220. In this case, the priority order can include: for single-cell operation with two uplink carriers or for operation with carrier aggregation, if the total UE transmit power for PUSCH or PUCCH or PRACH or SRS transmission on the serving cell in the frequency range in the corresponding transmission opportunity would exceed the configured maximum transmit power, the UE 210 allocates power to the PUSCH / PUCCH / PRACH / SRS transmission according to the following priority order (in descending order) so that the total UE transmit power for transmission on the serving cell in the frequency range is less than or equal to the configured maximum transmit power for the frequency range in each symbol of the transmission opportunity:

[0136] -PRACH transmission on PCell

[0137] - PUCCH, SRS, or PUSCH transmissions associated with no panel ID or with a lower panel ID

[0138] - PUCCH or PUSCH transmission with a higher priority index

[0139] - For PUCCH or PUSCH transmissions with the same priority index

[0140] o PUCCH transmission with HARQ-ACK information, and / or SR, and / or LRR, or PUSCH transmission with HARQ-ACK information

[0141] o PUCCH transmission with CSI or PUSCH transmission with CSI

[0142] o PUSCH transmission without HARQ-ACK information or CSI, and for Type 2 random access procedure,

[0143] PUSCH transmission on PCell

[0144] - SRS transmission, where aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell other than the PCell

[0145] - PUCCH, SRS or PUSCH transmissions associated with a higher panel ID

[0146] Thus, the UE 210 following the priority order may include identifying a first priority for a first transmission type (e.g., HARQ-ACK, SR, LRR, etc.) for a first uplink transmission on the first transmission panel 215, which may be a higher priority than a second priority for a second transmission type for the first uplink transmission on the first transmission panel 215.

[0147] In some aspects of this example, the priority order of multi-panel uplink transmissions may correspond to priority index > panel > channel. For example, during a multi-panel uplink transmission, UE 210 may transmit a first uplink transmission on a first transmit panel 215 using a first transmit power and transmit a second uplink transmission on a second transmit panel using a second transmit power. In the case where the priority indexes are the same, and for operation with carrier aggregation, UE 210 prioritizes power allocation for transmissions on one panel over transmissions on another panel. Thus, UE 210 may identify or otherwise determine that the first priority of the first uplink transmission is a higher priority than the second priority for the second uplink transmission. During a multi-panel uplink transmission, UE 210 may prioritize based on the first priority of the first uplink transmission and the second priority of the second uplink transmission.

[0148] In some aspects, the priority order priority index > panel > channel can be based on an index or other identifier (e.g., panel ID) of the transmission panel of UE 210. For example, UE 210 can identify a first identifier for a first transmission panel associated with a first priority and a second identifier for a second transmission panel 220 associated with a second priority. In this example, the first priority is a higher priority than the second priority. Therefore, UE 210 can identify a first transmission type for a first uplink transmission on the first transmission panel 215 and a second transmission type for a second transmission on the second transmission panel 220. In this example, the first transmission type can be associated with a lower priority than the second transmission type. UE 210 can transmit the second transmission type for the second uplink transmission on the second transmission panel 220 and discard the first transmission type for the first uplink transmission on the first transmission panel 215. Thus, the priority order may include: for single-cell operation with two uplink carriers or for operation with carrier aggregation, if the total UE transmit power for PUSCH or PUCCH or PRACH or SRS transmissions on the serving cell in a frequency range in the corresponding transmission opportunity would exceed the configured maximum transmit power, the UE 210 allocates power to the PUSCH / PUCCH / PRACH / SRS transmissions according to the following priority order (in descending order) such that the total UE transmit power for transmissions on the serving cell in the frequency range is less than or equal to the configured maximum transmit power for the frequency range in each symbol of the transmission opportunity:

[0149] -PRACH transmission on PCell

[0150] - PUCCH or PUSCH transmission with a higher priority index

[0151] - PUCCH or PUSCH transmission with no panel ID or with a lower panel ID having a higher priority than a higher panel ID

[0152] - For PUCCH or PUSCH transmissions with the same priority index and no panel ID or with a lower panel ID

[0153] o PUCCH transmission with HARQ-ACK information, and / or SR, and / or LRR, or PUSCH transmission with HARQ-ACK information

[0154] o PUCCH transmission with CSI or PUSCH transmission with CSI

[0155] o PUSCH transmission without HARQ-ACK information or CSI, and for Type 2 random access procedure,

[0156] PUSCH transmission on PCell

[0157] - SRS transmission with no panel ID or with a lower panel ID, where aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell other than the PCell with no panel ID or with a lower panel ID

[0158] - For PUCCH or PUSCH transmissions with the same priority index and with a higher panel ID

[0159] - SRS transmission with a higher panel ID, where aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell other than the PCell with a higher panel ID

[0160] In some aspects of this example, the priority order may correspond to priority index > channel > panel. For example, UE 210 may identify or otherwise determine a first priority of a first transmission type for a first uplink transmission that has a higher priority than a second priority of a second transmission type for a second uplink transmission. In this case, prioritization of transmit power on a per-transmit panel basis may be based on a first priority for the first transmission type and a second priority for the second transmission type. In the case of the same priority order (e.g., the priority index and channel type are the same for the first and second uplink transmissions), and for operation of carrier aggregation, UE 210 may prioritize power allocation for transmissions on one panel over transmissions on another panel.

[0161] In some aspects, the priority order of priority index > channel > panel may be based on an index or other identifier (e.g., panel ID) of the transmit panel of UE 210. For example, UE 210 may identify a first identifier for a first transmit panel 215 associated with a first priority and a second identifier for a second transmit panel 220 associated with a second priority. The first priority may be a higher priority than the second priority, or vice versa. UE 210 may identify a first transmission type for a first uplink transmission on the first transmit panel 215 and a second transmission type for a second uplink transmission on the second transmit panel 220. In this case, the first transmission type may be associated with a lower priority than the second transmission type. Therefore, UE 210 may transmit the second transmission type for the second uplink transmission on the second transmit panel 220 and discard the first transmission type for the first uplink transmission on the first transmit panel 215. In the case of the same priority order, and for operation with carrier aggregation and multi-panel transmission, UE 210 prioritizes power allocation for transmissions associated with a lower panel ID or no panel ID over transmissions associated with a higher panel ID. Thus, the priority order may include: for single-cell operation with two uplink carriers or for operation with carrier aggregation, if the total UE transmit power for PUSCH or PUCCH or PRACH or SRS transmissions on the serving cell in a frequency range in the corresponding transmission opportunity would exceed the configured maximum transmit power, the UE 210 allocates power to the PUSCH / PUCCH / PRACH / SRS transmissions according to the following priority order (in descending order) such that the total UE transmit power for transmissions on the serving cell in the frequency range is less than or equal to the configured maximum transmit power for the frequency range in each symbol of the transmission opportunity:

[0162] -PRACH transmission on PCell

[0163] - PUCCH or PUSCH transmission with a higher priority index

[0164] - PUCCH or PUSCH transmission with no panel ID or with a lower panel ID having a higher priority than a higher panel ID

[0165] - For PUCCH or PUSCH transmissions with the same priority index

[0166] o PUCCH transmission with HARQ-ACK information, and / or SR, and / or LRR, or PUSCH transmission with HARQ-ACK information without a panel ID or with a lower panel ID having a higher priority than a higher panel ID

[0167] o PUCCH transmission with CSI or PUSCH transmission with CSI without a panel ID or with a lower panel ID having a higher priority than that of a higher panel ID

[0168] o PUSCH transmissions without HARQ-ACK information or CSI with no panel ID or with a lower panel ID having a higher priority than that of a higher panel ID, and for a Type 2 random access procedure,

[0169] PUSCH transmission on PCell

[0170] - SRS transmission, where aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS, or PRACH transmission on a serving cell other than the PCell

[0171] - SRS transmission with no panel ID or with a lower panel ID having a higher priority than a higher panel ID

[0172] As described above, the base station 205 may send a configuration signal to the UE 210 indicating configuration information, such as a priority order for multi-panel uplink transmissions including the first transmit panel 215 and the second transmit panel 220. Thus, in some examples, the configuration signal may be RRC signaling / configuration. As also discussed, the configuration signal may be from higher layers of the UE 210 and may be received at lower layers of the UE 210. In some aspects, the priority order of the transmit panels of the UE 210 used during multi-panel uplink transmissions may include or otherwise be based on (e.g., the transmit panels of the UE 210 may correspond to or otherwise refer to) a special control resource set (CORESET) pool index (e.g., a lower CORESET pool index), a special SRS ID (e.g., a lower SRS set index), a special closed-loop index (e.g., a lower CLI index), etc.

[0173] Thus, UE 210 can perform a multi-panel uplink transmission to base station 205 using at least a first transmit panel 215 at a first transmit power and a second transmit panel 220 at a second transmit power. The first transmit power and the second transmit power can be based on the available transmit power and can be selected, at least in some aspects, based on a priority associated with each transmit panel. Base station 205 can receive and process the multi-panel uplink transmission according to the techniques discussed above (e.g., based on the priority order indicated to UE 210 and / or the available transmit power).

[0174] Figures 3A to 3C An example of a transmit panel configuration 300 supporting transmit power prioritization for multi-panel uplink transmissions according to aspects of the present disclosure is shown. In some examples, the transmit panel configuration 300 can be implemented by or can implement aspects of the wireless communication systems 100 and / or 200. Aspects of the transmit panel configuration 300 can be implemented by a UE and / or a base station (which can be examples of corresponding devices described herein). In general, Figure 3A The sending panel configuration 300-a shows an example of applying the described technology in an SDM scenario. Figure 3B The transmission panel configuration 300-b shows an example of applying the described technology in an FDM scenario, and Figure 3C The transmit panel configuration 300 - c shows an example of applying the described techniques in a TDM scenario.

[0175] As described above, the UE can support multi-panel uplink transmissions to the base station using one or more transmit panels of the UE (such as the first transmit panel 305 and the second transmit panel 310). Generally, the transmit panel of the UE can refer to any configuration of hardware (e.g., antennas) and / or software (e.g., beamforming techniques, directional transmission techniques, weighting criteria, etc.) used to perform uplink transmissions. For example, the transmit panel can refer to a specific TPMI configured for the UE, an SRI configured for the UE, a TCI configured for the UE, etc. In some examples, the transmit panel of the UE can refer to different antennas of the UE and / or to antennas of the UE that transmit using different configurations. In some examples, two or more transmit panels of the UE (e.g., the first transmit panel 305 and the second transmit panel 310) are used to perform multi-panel uplink transmissions using various multiplexing techniques (such as SDM, FDM, TDM, a combination of two or more of SDM, FDD, and TDM, etc.). In this example, the transmit panel of the UE can refer to a transmit panel used to perform uplink transmissions on a specific spatial configuration for SDM, on a specific frequency for FDM, at a specific time for TDM, etc. In some aspects, the sending panel may refer to a special panel ID (e.g., a lower panel ID) with a special CORESET pool index (e.g., a lower CORESET pool index), with a special SRS ID (e.g., a lower SRS set index), with a special closed-loop index (e.g., a lower CLI index), etc.

[0176] For example, the UE and the base station may determine that the UE will use two or more transmission panels of the UE (e.g., a first transmission panel 305 and a second transmission panel 310) to perform a multi-panel uplink transmission. The UE and the base station may identify a priority order for uplink transmissions for performing the multi-panel uplink transmission, wherein the UE's transmission panel has a corresponding priority configured for each panel. The UE and the base station may also identify or otherwise determine the available transmit power for the multi-panel uplink transmission and perform the transmission according to the priority order and the available transmit power. For example, the UE may use a first transmission panel 305 at a first transmit power and a second transmission panel 310 at a second transmit power, the first transmit power and the second transmit power being based on the available transmit power for the multi-panel uplink transmission and taking into account the priority order of the UE's transmission panels. Thus, when allocating available transmit power for a multi-panel uplink transmission from the UE to the base station, the UE and the base station may enable per-transmission panel priority considerations.

[0177] More specifically and with reference to Figure 3A In the case of a transmission panel configuration 300-a, a multi-panel uplink transmission can utilize SDM technology such that a first uplink transmission performed using a first transmission panel 305 at a first transmission power is transmitted using a first spatial configuration. A second uplink transmission performed using a second transmission panel 310 at a second transmission power can be transmitted using a second spatial configuration that is different from the first spatial configuration. For example, the first spatial configuration being different from the second spatial configuration can correspond to using different beamforming configurations for the first uplink transmission and the second uplink transmission. This can allow the UE to simultaneously (e.g., in parallel) transmit a first uplink transmission using the first transmission panel 305 at a first transmission power and transmit a second uplink transmission using the second transmission panel 310 at a second transmission power using the same frequency resources.

[0178] Reference Figure 3B In the transmission panel configuration 300-b, the multi-panel uplink transmission can utilize FDM technology, so that the first uplink transmission performed using the first transmission panel 305 at a first transmission power is sent using a first frequency. The second uplink transmission performed using the second transmission panel 310 at a second transmission power can be sent using a second frequency that is different from the first frequency. For example, the first frequency being different from the second frequency can correspond to using different subcarriers, carriers, bandwidths, bandwidth parts (BWPs), etc. for the first uplink transmission and the second uplink transmission. This allows the UE to simultaneously (e.g., in parallel) use the first transmission panel 305 to send the first uplink transmission at the first transmission power, but use different frequency resources to send the second uplink transmission using the second transmission panel 310 at the second transmission power.

[0179] Reference Figure 3C In the transmission panel configuration 300-c, the multi-panel uplink transmission can utilize TDM technology, so that the first uplink transmission performed using the first transmission panel 305 at the first transmission power is transmitted at a first time period. The second uplink transmission performed using the second transmission panel 310 at the second transmission power can be transmitted at a second time period different from the first time period. For example, the first time period being different from the second time period can correspond to using different symbols, mini-slots, time slots, transmission opportunities, transmission timings, etc. for the first uplink transmission and the second uplink transmission. This can allow the UE to use the first transmission panel 305 to send the first uplink transmission at the first transmission power at different times (e.g., continuously), but use the same frequency resources to send the second uplink transmission using the second transmission panel 310 at the second transmission power.

[0180] Thus, the UE may perform a multi-panel uplink transmission to the base station using at least a first transmit panel 305 at a first transmit power and a second transmit panel 310 at a second transmit power. The first transmit power and the second transmit power may be based on the available transmit power and may be selected, at least in some aspects, based on a priority associated with each transmit panel. The base station may receive and process the multi-panel uplink transmission according to the techniques discussed above, for example, based on the priority order indicated to the UE and / or the available transmit power. The multi-panel uplink transmission may utilize SDM, FDM, and / or TDM techniques, alone or in any combination (e.g., SDM and FDM, or FDM and TDM, or SDM and TDM, or all three of SDM, FDM, and TDM).

[0181] Figure 4 An example of a process 400 for supporting transmit power prioritization for multi-panel uplink transmissions according to aspects of the present disclosure is shown. In some examples, process 400 can be implemented by or implement aspects of wireless communication systems 100 and / or 200 and / or transmit panel configuration 300. Aspects of process 400 can be implemented by UE 405 and / or base station 410 (which can be examples of corresponding devices described herein). In some aspects, UE 405 can be configured to support multi-panel uplink transmissions to base station 410 using at least a first transmit panel and a second transmit panel of UE 405.

[0182] At 415, UE 405 may determine to perform a multi-panel uplink transmission. The multi-panel uplink transmission may use at least a first transmit panel and a second transmit panel of UE 405. In some aspects, this may be based on UE 405 determining that it has uplink information to send to base station 410 (e.g., in a transmit buffer). Accordingly, UE 405 may send or otherwise communicate an indication of an SR to base station 410 indicating that a multi-panel uplink transmission is to be performed. In another example, this may be based on request and / or scheduled information to be provided to base station 410, such as HARQ-ACK information scheduled for transmission to base station 410.

[0183] At 420, base station 410 may determine to perform a multi-panel uplink transmission from UE 405. The multi-panel uplink transmission may use at least a first transmit panel and a second transmit panel of UE 405. In some aspects, this may be based on an indication of uplink data to be transmitted by UE 405 and / or based on request and / or scheduling information to be provided by UE 405 to base station 410.

[0184] At 425, UE 405 may identify a priority order for uplink transmissions for performing multi-panel uplink transmissions. The priority order may include priority levels associated with a first transmission panel and a second transmission panel. In some aspects, this may include UE 405 identifying that a first priority level of the first transmission panel is a higher priority level than a second priority level of the second transmission panel. In this case, prioritizing available transmit power may be based on the first priority level of the first transmission panel being a higher priority level than the second priority level of the second transmission panel, or vice versa.

[0185] At 430, base station 410 may identify a priority order for uplink transmissions for UE 405 to perform multi-panel uplink transmissions. The priority order may include priorities associated with a first transmit panel and a second transmit panel of UE 405. In some aspects, this may include base station 410 identifying a first priority for the first transmit panel that has a higher priority than a second priority for the second transmit panel. Prioritization of transmit power for the multi-panel uplink transmissions of UE 405 may be based on the first priority of the first transmit panel and the second priority of the second transmit panel.

[0186] In some aspects, this can include the base station 410 identifying a first identifier for a first transmission panel associated with a first priority and a second identifier for a second transmission panel associated with a second priority. In this example, the second priority can be a lower priority than the first priority. The base station 410 can identify a first transmission type for a first uplink transmission on the first transmission panel and a second transmission type for a second uplink transmission on the second transmission panel. The first transmission type can be associated with a lower priority than the second transmission type. In this case, the base station 410 can receive the second transmission type for the second uplink transmission on the second transmission panel, wherein the UE 405 discards the first transmission type for the first uplink transmission on the first transmission panel.

[0187] At 435, UE 405 may identify an available transmit power for multi-panel uplink transmission. In some aspects, this may include base station 410 transmitting (and UE 405 receiving) a configuration signal indicating a first available transmit power for a first transmit panel and a second available transmit power for a second transmit panel. The available transmit power for multi-panel uplink transmission may be based on the first available transmit power and the second available transmit power.

[0188] In some aspects, this can include UE 405 determining that the first transmit power exceeds a first available transmit power for a first transmit panel. Accordingly, UE 405 can identify that a first priority for a first transmission type for a first uplink transmission on the first transmit panel is higher than a second priority for a second transmission type for a second uplink transmission on the first transmit panel. UE 405 can transmit the first transmission type for the first uplink transmission on the first transmit panel and discard the second uplink transmission on the first transmit panel. In some aspects, a configuration signal can be received from base station 410. In other aspects, the configuration signal can be received at a lower layer of UE 405 from a higher layer of UE 405.

[0189] In some aspects, this may include the UE 405 receiving a configuration signal indicating shared available transmit power, wherein the available transmit power for multi-panel uplink transmissions corresponds to the shared available transmit power.

[0190] At 440, base station 410 may identify available transmit powers for UE 405 for multi-panel uplink transmissions. In some aspects, this may include base station 410 transmitting (and UE 405 receiving) a configuration signal indicating a first available transmit power for a first transmit panel and a second available transmit power for a second transmit panel. The first transmit power may be based on the first available transmit power, and the second transmit power may be based on the second available transmit power.

[0191] In some aspects, this can include base station 410 sending (and UE 405 receiving) a configuration signal indicating a shared available transmit power for multi-panel uplink transmissions. The first transmit power and the second transmit power can be based on the shared available transmit power, which can correspond to the available transmit power for multi-panel uplink transmissions.

[0192] At 445, the UE 405 may transmit (and the base station 410 may receive) a multi-panel uplink transmission using at least a first transmit panel at a first transmit power and a second transmit panel at a second transmit power according to a priority order. In at least some aspects, the first transmit power and the second transmit power may be based on available transmit power and a priority associated with each transmit panel.
