Abstract
Description
Technical Field
[0001] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for configuring shared transmit power of multiple antenna panels of user equipment. Background Art
[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).
[0003] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as a user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, among other examples).
[0004] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region, and / or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the invention

[0026] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.
[0027] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the application and the design constraints imposed on the overall system.
[0028] Although various aspects may be described herein using terminology generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G (e.g., 6G) RAT.
[0029] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).
[0030] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. For example, the network node 110 may include an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.
[0031] In some examples, the network node 110 may provide communication coverage for a geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to a coverage area of the network node 110 and / or a network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. The network node may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographic area of the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).
[0032] In some aspects, the term "base station" or "network node" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not the other. In this way, a single device may include more than one base station.
[0033] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communications between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.
[0034] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).
[0035] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.
[0036] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.
[0037] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0038] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support RATs and may operate on one or more frequencies. RATs may be referred to as radio technologies, air interfaces, etc. Frequencies may be referred to as carriers, frequency channels, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.
[0039] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.
[0040] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).
[0041] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). The bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus may effectively extend the features of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz–71 GHz), FR4 (52.6 GHz–114.25 GHz), and FR5 (114.25 GHz–300 GHz). Each of these higher frequency bands falls within the EHF band.
[0042] In view of the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0043] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive configuration information corresponding to transmit power control associated with simultaneous transmission by multiple antenna panels of the UE, wherein the configuration information indicates a plurality of configured maximum output power values corresponding to respective antenna panels of the plurality of antenna panels, wherein the plurality of configured maximum output power values are based on at least one of a set of per-panel transmit power constraints or a set of cross-panel transmit power constraints; and transmit a plurality of simultaneous uplink signals based on the configuration information. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0044] In some aspects, the network node may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send to a UE configuration information corresponding to transmit power control associated with simultaneous transmission by multiple antenna panels of the UE, wherein the configuration information indicates a plurality of maximum output power values corresponding to respective antenna panels of the multiple antenna panels, wherein the plurality of maximum output power values are based on at least one of a set of per-panel transmit power constraints or a set of cross-panel transmit power constraints; and receive a plurality of simultaneous uplink signals based on the configuration information. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0045] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.
[0046] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.
[0047] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).
[0048] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.
[0049] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.
[0050] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.
[0051] Each of the antenna elements may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element that is cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. The antenna elements may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements may allow signals having desired wavelengths transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam). For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half wavelength, or other fraction of a wavelength of the spacing between adjacent antenna elements to allow interaction or interference of signals transmitted by individual antenna elements within the desired range.
[0052] Antenna elements and / or sub-elements may be used to generate beams. A "beam" may refer to a directional transmission, such as a wireless signal transmitted in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal.
[0053] As indicated above, antenna elements and / or sub-elements can be used to generate beams. For example, antenna elements can be individually selected or deselected for transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers. Beamforming includes generating beams using multiple signals on different antenna elements, wherein one or more or all of the multiple signals are shifted in phase relative to each other. The formed beams may carry physical or higher layer reference signals or information. When each of the multiple signals is radiated from the corresponding antenna element, the radiated signals interact, interfere (constructively and destructively), and amplify with each other to form the resulting beam. The shape (such as amplitude, width, and / or the presence of side lobes) and direction (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shift or phase offset of the multiple signals relative to each other.
[0054] Beamforming may be used for communication between a UE and a network node, such as for millimeter wave communication, etc. In this case, the network node may provide the UE with a configuration of a transmit configuration indicator (TCI) state, which indicates beams that may be used by the UE, such as for receiving a physical downlink shared channel (PDSCH). The network node may indicate an activated TCI state to the UE, which the UE may use to select a beam for receiving the PDSCH.
[0055] The beam indication may be or include a TCI state information element, a beam ID, spatial relationship information, a TCI state ID, a closed loop index, a panel ID, a TRP ID, and / or a sounding reference signal (SRS) set ID, etc. The TCI state information element (referred to herein as TCI state) may indicate information associated with a beam, such as a downlink beam. For example, the TCI state information element may indicate a TCI state identifier (e.g., tci-StateID), a quasi co-location (QCL) type (e.g., qcl-Type1, qcl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, qcl-TypeD, etc.), a cell identifier (e.g., ServCellIndex), a bandwidth part identifier (bwp-Id), a reference signal identifier (such as a channel state information (CSI) reference signal (CSI-RS) (e.g., NZP-CSI-RS-ResourceId, SSB-Index, etc.)), etc. The spatial relationship information may similarly indicate information associated with an uplink beam.
[0056] The beam indication may be a joint or separate downlink (DL) / uplink (UL) beam indication in a unified TCI framework. In some cases, the network may use at least UE-specific (unicast) downlink control information (DCI) to indicate a joint or separate DL / UL beam indication from an active TCI state, thereby supporting beam indication based on layer 1 (L1). In some cases, existing DCI formats 1_0, 1_1, 1_2, 0_1, 0_2, 0_0, and / or 2_x may be reused for beam indication. For example, a DCI transmission may include a beam indication with one of six types of beam indications regarding a unified TCI. Type 1 may include a joint DL / UL common TCI state (joint TCI) for indicating a common beam for at least one DL channel and / or reference signal plus at least one UL channel and / or reference signal. Type 2 may include a separate DL common TCI state for indicating a common beam for more than one DL channel and / or reference signal. Type 3 may include separate UL common TCI states for indicating a common beam for more than one UL channel and / or reference signal. Separate DL and UL TCI state types may be referred to as "directional" TCI types because each TCI type corresponds to a respective communication direction (UL or DL). The source reference signal in the unified TCI may provide QCL information for at least one of PDSCH and physical downlink control channel (PDCCH) reception in the serving cell, and the source reference signal in the unified TCI (if applicable) may provide a reference for determining a common spatial transmit filter for at least one of SRS, physical uplink shared channel (PUSCH), and physical uplink control channel (PUCCH) transmissions in the serving cell.
[0057] Beam indication may be provided for carrier aggregation (CA) scenarios. In a unified TCI framework, the network may support common TCI state ID update and activation information to provide common QCL and / or one or more common UL transmit spatial filters across a set of configured component carriers (CCs). This type of beam indication may be applicable to intra-band CA as well as joint DL / UL beam indication and directional DL / UL beam indication. A common TCI state ID may mean that a reference signal (RS) determined according to the TCI state indicated by the common TCI state ID is used to provide QCL type D indication and determine the UL transmit spatial filter across a set of configured CCs.
[0058] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to execute the instructions described herein (eg, reference Figures 5 to 9 ) any aspects of any of the methods described herein.
[0059] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute the instructions described herein (e.g., reference 2 Figures 5 to 9 ) any aspects of any of the methods described herein.
[0060] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the UE 120 may perform one or more techniques associated with configuring the shared transmit power of multiple antenna panels of the UE, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 6 The process of 600 Figure 7 10 and / or operations of process 700 and / or other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 6 The process of 600 Figure 7 The process 700 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.
[0061] In some aspects, a UE (e.g., UE 120) includes: a component for receiving configuration information corresponding to transmit power control associated with simultaneous transmission by multiple antenna panels of the UE, wherein the configuration information indicates a maximum output power value for a plurality of configurations corresponding to respective antenna panels of the plurality of antenna panels, wherein the maximum output power value for the plurality of configurations is based on at least one of a set of per-panel transmit power constraints or a set of cross-panel transmit power constraints; and / or a component for transmitting a plurality of simultaneous uplink signals based on the configuration information. The components for the UE to perform the operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.
[0062] In some aspects, a network node (e.g., network node 110) includes: means for sending to a UE configuration information corresponding to transmit power control associated with simultaneous transmission by multiple antenna panels of the UE, wherein the configuration information indicates a plurality of maximum output power values corresponding to respective antenna panels of the multiple antenna panels, wherein the plurality of maximum output power values are based on at least one of a set of per-panel transmit power constraints or a set of cross-panel transmit power constraints; and / or means for receiving a plurality of simultaneous uplink signals based on the configuration information. In some aspects, means for a network node to perform operations described herein may include, for example, one or more of a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.
[0063] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.
[0064] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.
[0065] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways using various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station, or a network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP, or a cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or a "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).
[0066] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. The DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.
[0067] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.
[0068] Figure 3 3 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.
[0069] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, and the wireless interface being configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, or to perform both.
[0070] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface such as an E1 interface. As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.
[0071] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.
[0072] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions based on functional splits (e.g., functional splits defined by 3GPP) such as lower layer functional splits, or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.
[0073] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.
[0074] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or communicate with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.
[0075] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).
[0076] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.
[0077] Figure 4 4 is a diagram illustrating an example 400 of multiple transmit receive point (mTRP) operation according to the present disclosure. As shown, a UE 405 may communicate with a first TRP 410 and a second TRP 415. The UE 405 may be configured with single DCI based mTRP operation (e.g., Figure 4 In some cases, UE 405 may be configured with mTRP operation based on multiple DCIs. In some aspects, TRP 410 and / or TRP 415 may be, include, or be included in one or more network nodes (e.g., as described above in conjunction with Figure 1 and Figure 2 10) described above. For example, different TRPs 410 and 415 may be included in different network nodes. In some cases, multiple TRPs 410 and 415 may be included in a single network node. In some cases, TRP 410 and / or TRP 415 may be referred to as a cell, a panel, an antenna array, or an array. UE 405 may be, include, or be included in the above combined Figure 1 and Figure 2 In the UE 120 described.
[0078] Multiple TRPs 410 and TRPs 415 may transmit communications (e.g., the same communication or different communications) in the same transmit time interval (TTI) (e.g., time slot, mini-time slot, subframe, or symbol) or in different TTIs using different QCL relationships (e.g., different spatial parameters, different TCI states, different pre-coding parameters, or different beamforming parameters). TCI states may be used to indicate one or more QCL relationships. TRPs 410 may be configured to serve traffic to UE 405 individually (e.g., using dynamic selection) or jointly (e.g., using joint transmission with one or more other TRPs 410).
[0079] As shown, when configured with single-DCI based multi-TRP operation, UE 405 may receive a DCI transmission 420 from TRP 410 in a PDCCH transmission (shown as "PDCCH1"), where the DCI transmission 420 may schedule a first PUSCH transmission 425 for transmission to the first TRP 410. The DCI transmission 420 may also schedule a second PUSCH transmission 430 for transmission to the second TRP 415. In some cases, the DCI transmission 420 may schedule one or more PDSCH transmissions in addition to or in lieu of the PUSCH transmission. In association with monitoring the DCI transmitted from the first TRP 410, the UE 405 may monitor PDCCH candidates in PDCCH monitoring opportunities configured by the network in a number of different core resource sets (CORESETs). In some cases, UE 405 may be configured with multi-DCI based mTRP communication, where DCI 420 schedules PUSCH 425 and additional DCI transmissions received from TRP 415 schedule PUSCH 430.
[0080] Since the UE may emit RF waves, microwaves, and / or other radiation, the UE is generally subject to regulatory RF safety requirements that specify specific guidelines or maximum permissible exposure (MPE) limits that constrain various operations that the UE may perform. For example, when the UE is transmitting, the RF emissions may generally increase, and may further increase in situations where the UE is performing frequent transmissions and / or high-power transmissions, etc. Therefore, because frequent and / or high-power transmissions may result in significant RF emissions, regulatory agencies (e.g., the Federal Communications Commission (FCC) in the United States) provide information related to acceptable RF radiation exposure when the UE is communicating using different radio access technologies.
[0081] For example, when the UE is communicating using a radio access technology operating in a frequency range below 6 GHz, the applicable RF exposure parameter is the specific absorption rate (SAR), which refers to the rate at which energy is absorbed by a human body when exposed to RF energy (e.g., power absorbed per unit mass, which may be expressed in terms of watts per kilogram (W / kg)). SAR requirements typically specify that the total radiated power of the UE be kept below a certain level to limit the heating that may occur when absorbing RF energy. In another example, when the UE is communicating using a radio access technology operating in a high frequency range, such as a millimeter wave (mmW) frequency range, the applicable RF exposure parameter is power density, which may be adjusted to limit heating of the UE and / or nearby surfaces.
[0082] Therefore, the UE may take steps to meet MPE limits, which are usually regulatory requirements defined in terms of aggregate exposure over a certain amount of time, and the aggregate exposure may be averaged over a moving integration window (or moving time window). For example, the UE may be subject to an average power limit (P limit ), the average power limit corresponds to the average power that meets the MPE limit if the UE were to transmit substantially continuously over a mobile integration window of N seconds (e.g., 100 seconds). In some cases, the UE may reduce the transmit power to meet the MPE limit by applying a power management maximum power reduction (P-MPR). The P-MPR may refer to the maximum allowed UE output power reduction of the serving cell. In some aspects, the UE reports the power backoff level due to the P-MPR as the MPE value.
[0083] Uplink transmit power control may determine the transmit power used for PUSCH, PUCCH, SRS and / or PRACH transmissions.
[0084] UE 405 may configure its maximum output power. Configured UE maximum output power P for carrier f serving cell c CMAX,f,c can be set (eg, determined) such that the corresponding measured peak effective isotropic radiated power (EIRP) P UMAX,f,c Within the following limits:
[0085] P Powerclass +ΔP IBE -MAX(MAX(MPR f,c , A-MPR f,c ,)+ΔMB P,n , P-MPR f,c )-MAX{T(MAX(MPR f,c , A-MPR f,c ,)), T(P-MPR f,c )}≤PUMAX,f,c ≤EIRP max
[0086] The corresponding measured total radiated power P TMAX,f,c Defined by:
[0087] P TMAX,f,c ≤TRP max ,
[0088] Where P Powerclass It is the UE power class specified in the wireless communication standard (eg, subclause 6.2.1 of 3GPP TS 38.101-2 V17).
[0089] UE power class refers to the classification of UE based on the transmit power characteristics associated with the UE. For example, the first UE power class may include fixed wireless access UEs, the second UE power class may include vehicle-mounted UEs, the third UE power class may include handheld UEs, the fourth UE power class may include high-power non-handheld UEs, the fifth UE power class may include low-power fixed wireless access UEs, the sixth UE power class may include high-speed train roof-mounted UEs, and / or the seventh UE power class may include reduced-capability UEs, etc. Each UE power class may have a corresponding specified power limit, such as a maximum total radiated power and / or a maximum EIRP, etc.
[0090] In the maximum output power formula for the configuration indicated above, EIRP max is the applicable maximum EIRP, MPR, specified in the wireless communication standard (e.g., subclause 6.2.1 of 3GPPT S 38.101-2 V17) f,c is the maximum power reduction (e.g., the reduction in maximum output power due to modulation order, transmit bandwidth configuration, waveform type, and narrow allocation) specified in the wireless communication standard (e.g., subclause 6.2.2 of 3GPP TS 38.101-2 V17), A-MPR f,c is the additional MPR specified in the wireless communication standard (e.g., subclause 6.2.3 of 3GPP TS 38.101-2 V17) (e.g., applied to meet additional transmission requirements signaled by the network), ΔMB P,n is the peak EIRP relaxation specified in the wireless communication standard (e.g., clause 6.2.1 of 3GPP TS 38.101-2 V17) (e.g., for reducing the minimum requirement for peak EIRP in UE supporting multiple FR2 bands), and TRP max is the maximum total radiated power of the UE power class specified in the wireless communication standard (e.g., subclause 6.2.1 of 3GPP TS 38.101-2 V17).
[0091] The configured maximum output power determination may be used to configure the transmit power associated with one antenna panel of a UE in half-duplex operation. However, in some cases, a UE (e.g., UE 405) may be configured to transmit multiple simultaneous uplink signals using multiple antenna panels. For example, in Figure 4 , UE 405 may simultaneously transmit PUSCH 425 using a first antenna panel and PUSCH 430 using a second antenna panel. The above-described maximum output power configuration does not provide for sharing the maximum output power configuration between two or more antenna panels, and thus may not be sufficient to support simultaneous uplink signaling using multiple antenna panels in mTRP communications. Supporting transmit power sharing between multiple antenna panels of UE 405 may facilitate simultaneous uplink signaling, resulting in more efficient and flexible communications.
[0092] Some aspects of the techniques and apparatus described herein provide for configuring the shared transmit power of multiple antenna panels of a UE. For example, a UE (e.g., UE 405) may receive configuration information (as shown by reference numeral 435). The configuration information may correspond to a transmit power control associated with simultaneous transmissions performed by multiple antenna panels of the UE. The configuration information may indicate a maximum output power value for multiple configurations corresponding to corresponding antenna panels in the multiple antenna panels. The maximum output power values for the multiple configurations may be based on at least one of a set of per-panel transmit power constraints or a set of cross-panel transmit power constraints. The UE may transmit multiple simultaneous uplink signals based on the configuration information. In this way, some aspects of the techniques and apparatus described herein may help configure the shared transmit power of multiple antenna panels of a UE for simultaneous uplink transmissions. Therefore, some aspects may facilitate more efficient network communications and, therefore, positively impact network performance.
[0093] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.
[0094] Figure 55 is a flow chart illustrating an example 500 associated with configuring shared transmit power of multiple antenna panels of a UE in accordance with the present disclosure. As shown, a UE 502 and a network node 504 may communicate with each other. In some aspects, the UE 502 and the network node 504 may communicate with each other based on an mTRP configuration. In some aspects, the network node 504 may include a first TRP 506 and a second TRP 508, as shown. In some other aspects, one or both of the TRP 506 and the TRP 508 may be independent of the network node 504. The UE 502 may be, similar to, include, or be included in: Figure 5 UE 502 depicted in Figure 4 UE 405 and / or Figures 1 to 3 UE 120 depicted in FIG. The network node 504 may be, be similar to, include, or be included in: Figure 4 TRP 410 and / or TRP 415 and / or Figure 1 and Figure 2 A network node 110 is depicted in FIG.
[0095] As indicated by reference numeral 510, UE 502 may transmit capability information and network node 504 may receive the capability information. The capability information may indicate that UE 502 is capable of configuring transmit power based on at least one of a per-panel transmit power constraint or an inter-panel transmit power constraint.
[0096] As indicated by reference numeral 512, the network node 504 may send configuration information and the UE 502 may receive the configuration information. The configuration information may include an RRC configuration and may indicate any number of configurations. In some aspects, the configuration information may correspond to a transmit power control associated with simultaneous transmission by a plurality of antenna panels of the UE 502. The configuration information may indicate maximum output power values for a plurality of configurations corresponding to respective antenna panels in the plurality of antenna panels. In some aspects, the plurality of antenna panels may include, for example, a first antenna panel 514 and a second antenna panel 516.
[0097] The maximum output power values of the multiple configurations may be based on at least one of a set of transmit power constraints per panel or a set of transmit power constraints across panels. For example, in some aspects, the maximum output power values of the multiple configurations may be based only on a set of transmit power constraints per panel. In some aspects, the maximum output power values of the multiple configurations may be based only on a set of transmit power constraints across panels. In some aspects, the maximum output power values of the multiple configurations may be based on a set of transmit power constraints per panel and a set of transmit power constraints across panels. In some aspects, the type of transmit power constraint associated with the configuration information may be based on capability information.

CMAX,f,c,1 will be determined so that the first measured maximum uplink power (P UMAX ) Satisfy the first P UMAX The first transmission power constraint may also indicate a maximum output power value P of a second configuration associated with the second antenna panel 516 among the maximum output power values of the plurality of configurations. CMAX,f,c,2 will be determined so that the second measured P UMAX Satisfy the second P UMAX condition.
[0100] In some aspects, the first measured P UMAX Based on the first measured P UMAX Not less than the lower limit and not greater than the maximum per-panel EIRP limit to meet the first P UMAX Condition. The second measured P UMAX Based on the second measured P UMAX Not less than the lower limit and not greater than the maximum per-panel EIRP limit to meet the second P UMAX The lower limit may be based on the power level associated with UE 502, the in-band transmission boost value ΔP IBE , MPR value, A-MPR value, P-MPR value and peak EIRP relaxation value.
[0101] In some aspects, the second transmit power constraint may indicate a first measured total radiated power (P TMAX ) is no greater than the first P associated with the first antenna panel 514 TMAX The second transmit power constraint may further indicate a second measured P associated with the second antenna panel 516. TMAX No greater than the second P associated with the second antenna panel 516 TMAX limit.
[0102] For example, in some aspects, a wireless communication standard may indicate a corresponding configured UE maximum output power P for carrier f serving cell c. CMAX,f,c,1 and P CMAX,f,c,2 should be set so that the corresponding measured peak EIRP P UMAX,f,c Respectively within the following limits:
[0103] P Powerclass +ΔP IBE -MAX(MAX(MPR f,c , A-MPR f,c ,)+ΔMB P,n , P-MPR f,c )-MAX{T(MAX(MPR f,c , A-MPR f,c ,)), T(P-MPR f,c )}≤P UMAX,f,c,1 ≤EIRP max, separate ;as well as
[0104] P Powerclass +ΔP IBE -MAX(MAX(MPR f,c , A-MPR f,c ,)+ΔMB P,n , P-MPR f,c )-MAX{T(MAX(MPR f,c , A-MPR f,c ,)), T(P-MPR f,c )}≤P UMAX,f,c,2 ≤EIRP max, separate ,
[0105] The corresponding measured total radiated power P TMAX,f,c,1 and P TMAX,f,c,2 Defined by:
[0106] P TMAX,f,c,1 ≤TRP max, separate ;as well as

[0108] Where P Powerclass is the UE power level, EIRP max, separate is the applicable maximum per-panel EIRP, and TRP max, separate It is the maximum total radiated power per panel for the UE power class.
[0109] In some aspects, the maximum output power values of the plurality of configurations may be based on a set of cross-panel transmit power constraints.The set of cross-panel transmit power constraints may include a first transmit power constraint and a second transmit power constraint.
[0110] In some aspects, the first transmit power constraint may indicate that a maximum output power value of a first configuration associated with the first antenna panel 514 among the maximum output power values of the plurality of configurations is to be determined such that the first measured P UMAXSatisfy the first P UMAX The first transmit power constraint may also indicate that a maximum output power value of a second configuration associated with the second antenna panel 516 among the maximum output power values of the plurality of configurations is to be determined such that the second measured P UMAX Satisfy the second P UMAX Conditions. The first measured P UMAX Based on the first measured P UMAX Not less than the lower limit to meet the first P UMAX Condition. The second measured P UMAX Based on the second measured P UMAX Not less than the lower limit to meet the second P UMAX In some aspects, the lower limit can be based on the power class associated with the UE, the in-band transmission boost value ΔP IBE , MPR value, A-MPR value, P-MPR value and peak EIRP relaxation value.
[0111] In some aspects, the second transmit power constraint may indicate that the peak EIRP measured across the first antenna panel 514 and the second antenna panel 516 is not less than the P measured across the first antenna panel 514 and the second antenna panel 516. UMAX The second transmit power constraint may further indicate a measured P across the first antenna panel 514 and the second antenna panel 516. TMAX No greater than P across the first antenna panel 514 and the second antenna panel 516 TMAX limit.
[0112] For example, in some aspects, a wireless communication standard may indicate a corresponding configured UE maximum output power P for carrier f serving cell c. CMAX,f,c,1 and P CMAX,f,c,2 should be set so that the corresponding measured peak EIRP P UMAX,f,c Within the following limits:

[0119] Where P Powerclass is the UE power level, EIRP max, total is the applicable maximum EIRP across both panels, and TRP max, total is the maximum total radiated power across two panels for the UE power class.
[0120] In some aspects, the first transmit power constraint may indicate that a maximum output power value of a first configuration associated with the first antenna panel 514 among the maximum output power values of the plurality of configurations is to be determined such that the measured P across the first antenna panel 514 and the second antenna panel 516 is UMAX Satisfy P UMAX The first transmit power constraint may further indicate that a maximum output power value of a second configuration associated with the second antenna panel 516 among the maximum output power values of the plurality of configurations may be determined such that the measured P UMAX Satisfy P UMAX In some aspects, the measured P UMAX Based on this measurement, P UMAX is not less than the lower limit and not greater than the maximum EIRP limit across the first antenna panel 514 and the second antenna panel 516 to meet P UMAXIn some aspects, the lower limit can be based on the power class associated with the UE, the in-band transmission boost value ΔP IBE , MPR value, A-MPR value, P-MPR value, and peak EIRP relaxation value. The second transmit power constraint may indicate a measured P across the first antenna panel 514 and the second antenna panel 516. TMAX No greater than P across the first antenna panel 514 and the second antenna panel 516 TMAX limit.
[0121] For example, in some aspects, a wireless communication standard may indicate a corresponding configured UE maximum output power P for carrier f serving cell c.
