Description

Technical Field

[0001] The present disclosure relates to wireless communications including transmitting a configuration indication (TCI) specific virtual power headroom report (PHR). Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (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, each of which supports wireless communication for a communication device, which may be referred to as a user equipment (UE).

[0003] The UE may communicate with a base station via one or more transmit receive points (TRPs). In some examples, techniques for calculating the power headroom associated with the TRPs may be improved. Summary of the invention

[0004] The described technology relates to improved methods, systems, devices and apparatuses for supporting a virtual power headroom report (PHR) specific to a transmission configuration indication (TCI). For example, the described technology provides a user equipment (UE) to perform a virtual PHR in a multiple transmission reception point (mTRP) system. In some examples, a network entity may configure a first set of power control parameters and a second set of power control parameters associated with a first TRP and a second TRP, respectively, to the UE. Each set of power control parameters may include a path loss reference signal (PLRS) parameter, a nominal power parameter, an alpha value parameter, a closed loop index parameter, a power management maximum power reduction (P-MPR) parameter, or a combination thereof. In some cases, at least a second set of power control parameters may be associated with a virtual PHR. The UE may send a message including a first PHR generated by the UE for a first uplink transmission (e.g., a scheduled physical uplink shared channel (PUSCH) transmission or a non-scheduled PUSCH transmission) using a first set of power control parameters. In addition, the message may include a second PHR generated by the UE for a reference uplink transmission (e.g., a non-scheduled PUSCH transmission) using a second set of power control parameters. Therefore, the UE may send two PHRs to a network entity based on the UE communicating with two TRPs having separate sets of uplink control parameters.

[0005] In some examples, the first uplink transmission and the reference uplink transmission may be associated with respective TCI states, and the network entity may configure these TCI states in the TCI configuration. Thus, the first set of power control parameters and the second set of power control parameters may be associated with respective TCI states. In addition, the network entity may indicate the first set of power control parameters and the second set of power control parameters and their association with the TRP and the corresponding reference signal resource index in an uplink bandwidth part (BWP) configuration or a serving cell configuration.

[0045] A user equipment (UE) may support power headroom reporting (PHR) for multiple transmit receive point (mTRP) wireless communications. A power headroom value may indicate how much transmit power is available to the UE for scheduled transmissions, and may be calculated based on a set of power control parameters as the difference between the maximum available transmit power and the estimated (e.g., required) transmit power of the scheduled transmission. If the power headroom value is positive, the UE may have sufficient transmit power to successfully transmit the scheduled transmission. If the power headroom value is negative, the UE may already be transmitting at or above the maximum transmit power. In some examples, the UE may generate a power headroom value for an actual uplink transmission (which may also be referred to as a scheduled uplink transmission) using a set of power control parameters, or the UE may generate a virtual power headroom value for a reference uplink transmission (which may also be referred to as a virtual uplink transmission or a non-scheduled uplink transmission) using the set of power control parameters. However, for virtual PHR, using a single set of power control parameters to generate power headroom values ​​for multiple scheduled or unscheduled uplink transmissions may increase latency and reduce the flexibility of power headroom calculation, particularly in mTRP systems where corresponding TRPs may be associated with different power control parameters.

[0046] The technology described herein supports the UE to perform a virtual PHR in an mTRP system. In some examples, the network entity may configure the UE with a first set of power control parameters and a second set of power control parameters associated with a first TRP and a second TRP, respectively. Each set of power control parameters may include a path loss reference signal (PLRS) parameter, a nominal power parameter, an alpha value parameter, a closed-loop index parameter, a power management maximum power reduction (P-MPR) parameter, or a combination thereof. In some cases, at least the second set of power control parameters may be associated with a virtual PHR. The UE may send a message including a first PHR generated by the UE for a first uplink transmission (e.g., a scheduled or non-scheduled physical uplink shared channel (PUSCH) transmission) using a first set of power control parameters. In addition, the message may include a second PHR generated by the UE for a reference uplink transmission (e.g., a non-scheduled PUSCH transmission) using a second set of power control parameters. Therefore, the UE may send two PHRs to the network entity based on the UE communicating with two TRPs having separate sets of uplink control parameters.

[0047] In some examples, the first uplink transmission and the reference uplink transmission may be associated with corresponding transmission configuration indicator (TCI) states, and the network entity may configure these TCI states via TCI configuration. Thus, the first set of power control parameters and the second set of power control parameters may be associated with the corresponding TCI states. In addition, the network entity may indicate the first set of power control parameters and the second set of power control parameters and their association with the TRP and the corresponding reference signal resource index in an uplink bandwidth part (BWP) configuration or a serving cell configuration.

[0048] Various aspects of the subject matter described herein may be implemented to achieve one or more of the following potential improvements, among others. The techniques employed by the described communication device may enable a UE to generate a PHR for different TRPs using a corresponding set or sets of power control parameters, which may increase the flexibility and accuracy of a virtual PHR. That is, the UE may more accurately generate a PHR for one or more scheduled or non-scheduled (e.g., virtual) uplink transmissions associated with a corresponding reference signal resource index, which may result in reduced latency and improved communication between a network entity and the UE, among other benefits.

[0049] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are also described in the context of a network architecture and process flow. Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow diagrams involving TCI-specific virtual PHRs.

[0050] Figure 1An example of a wireless communication system 100 supporting a TCI-specific virtual PHR according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 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, a new radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0051] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, etc. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area), and the UE 115 and the network entity 105 may establish one or more communication links 125 over the coverage area. The coverage area 110 may be an example of a geographic area, and the network entity 105 and the UE 115 may support signal communication over the geographic area according to one or more radio access technologies (RATs).

[0052] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein can communicate with various types of devices, such as Figure 1 Communicate with other UEs 115 or network entities 105) as shown.

[0053] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0054] In some examples, the network entities 105 may communicate with the core network 130, or with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, the network entities 105 may communicate with each other directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130) via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, the network entities 105 may communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or fronthaul communication links 168 (e.g., according to a fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0055] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a Home Node B, a Home Evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0056] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0057] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities, depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, and RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by the other of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 communicating over those communication links.

[0058] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to the core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as host entities or IAB hosts. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a host network entity 105 (e.g., a host base station 140). One or more host network entities 105 (e.g., IAB hosts) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB host. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0059] For example, an access network (AN) or RAN may include an access node (e.g., an IAB host), communications between an IAB node 104 and one or more UEs 115. The IAB host may facilitate a connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB host may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB host may include a CU 160 and at least one DU 165 (e.g., and RU 170), wherein the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB host and the IAB node 104 may communicate via an F1 interface according to a protocol defining a signaling message (e.g., an F1 AP protocol). Additionally or alternatively, the CU 160 may communicate with the core network via an interface (which may be an example of a portion of a backhaul link), and may communicate with other CUs 160 (e.g., CUs 160 associated with an alternative IAB host) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0060] The IAB node 104 may refer to a RAN node that provides IAB functions (e.g., access for UE 115, wireless self-backhaul capabilities, etc.). The DU 165 may act as a distributed scheduling node toward a child node associated with the IAB node 104, and the IAB-MT may act as a scheduled node toward a parent node associated with the IAB node 104. That is, the IAB host may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB host may be relayed for UE transmission through one or more other IAB nodes 104). Additionally or alternatively, depending on the relay chain or configuration of the AN, the IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104. Therefore, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104, and the DU interface (e.g., DU 165) may provide a Uu interface for the parent IAB node 104 to signal the child IAB node 104 or the UE 115.

[0061] For example, the IAB node 104 may be referred to as a parent node that supports child IAB node communications and as a child IAB node associated with the IAB donor. The IAB host may include a CU 160 having a wired or wireless connection (e.g., backhaul communication link 120) to the core network 130, and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB donor may relay transmission to the UE 115 via the IAB node 104, and may directly signal the UE 115 of the transmission. The CU 160 of the IAB donor may signal the IAB node 104 of the communication link establishment via the F1 interface, and the IAB node 104 may schedule the transmission (e.g., the transmission relayed from the IAB host to the UE 115) via the DU 165. That is, data may be relayed to and from the IAB node 104 via signaling on the NR Uu interface of the MT to the IAB node 104. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB host, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0062] Where the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support TCI-specific virtual PHRs as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0063] 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 suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. 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 may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0064] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1shown.

[0065] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) on one or more carriers. The term "carrier" may refer to a set of RF spectrum resources having a defined physical layer structure to support the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a BWP) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between a device and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0066] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be located based on a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be performed by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0067] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry either downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in TDD mode).

[0068] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz) of a carrier of a particular radio access technology. A device (e.g., a network entity 105, a UE 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communication on a particular carrier bandwidth or may be configurable to support communication on one of the carrier bandwidths in the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent 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 a carrier bandwidth.

[0069] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM technology, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be 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), so that the more resource elements a device receives and the higher the order of the modulation scheme, the higher the data rate for the device may be. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers, beams), and the use of multiple spatial resources may increase the data rate or data integrity of communications with UE 115.

[0070] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f) seconds, where Δf max It can represent the maximum supported subcarrier spacing, and N f The maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0071] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into multiple 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 multiple symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, the time slot may also be divided into multiple mini time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0072] A subframe, a slot, a mini-slot, or a 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 transmit time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0073] 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 set of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of the control channel candidate may refer to the amount 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 a plurality of UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0074] The network entity 105 may 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" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., on a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, such cells may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, as well as other examples.

[0075] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have a service subscription with a network provider that supports the macro cell. A small cell may be associated with a lower power network entity 105 (e.g., a lower power base station 140) (compared to a macro cell), and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell 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 a small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A network entity 105 may support one or more cells, and may also use one or more component carriers to support communications on one or more cells.

[0076] 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.

[0077] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0078] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for either synchronous operation or asynchronous operation.

[0079] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video, or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety applications or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency are used interchangeably herein.

[0080] In some examples, the UE 115 can communicate directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured or scheduled by the network entity 105. In some examples, one or more UEs 115 in such a group may be outside the coverage area 110 of the network entity 105, or may be unable or not configured to receive transmissions from the network entity 105 for other reasons. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, the network entity 105 may facilitate scheduling of resources for D2D communication. In some other examples, D2D communications may be conducted between UEs 115 without involving network entity 105 .

[0081] 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 for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnecting to an external network (e.g., a serving gateway (S-GW)), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered via the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 for one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0082] The wireless communication system 100 may operate using one or more frequency bands that may be 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 wavelength range is approximately one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but the waves may be sufficient to penetrate structures so that macro cells provide service to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than transmission using smaller frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0083] The wireless communication system 100 can utilize both licensed RF spectrum bands and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed RF spectrum band, devices such as network entities 105 and UE 115 can use carrier sensing for conflict detection and avoidance. In some examples, operations in unlicensed bands can be based on carrier aggregation configuration (e.g., LAA) in combination with component carriers operating in licensed bands. Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0084] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may have an antenna array having a set of rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0085] The network entity 105 or UE 115 may use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such technology may be referred to as spatial multiplexing. For example, multiple signals may be sent by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device 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 information 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 technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are sent to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are sent to multiple devices.

[0086] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape 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 may be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements may 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).

[0087] The network entity 105 or UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the network entity 105 along different directions. For example, the network entity 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105), or by a receiving device (such as UE 115)) beam directions for later transmission or reception by the network entity 105.

[0088] Some signals, such as data signals associated with a particular receiving device, may be sent by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device (such as receiving network entity 105 or receiving UE 115)). In some examples, the beam direction associated with the transmission along the single beam direction may be determined based on signals sent along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network entity 105 along different directions, and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0089] In some examples, transmission by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more subbands. Network entity 105 may send reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which may or may not be precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel codebook, linear combination codebook, port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0090] A receiving device (e.g., UE 115) may perform receiving operations according to multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple receiving directions by: receiving via different antenna subarrays, processing the received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing the received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along 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 other acceptable signal quality based on listening according to multiple beam directions).

[0091] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication at the bearer or PDCP layer can be IP-based. The RLC layer can perform packet segmentation and reorganization to communicate on the logical channel. The MAC layer can perform priority processing 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 RRC protocol layer can provide the establishment, configuration and maintenance of the RRC connection of the radio bearer that supports user plane data between the UE 115 and the network entity 105 or the core network 130. At the PHY layer, the transport channel can be mapped to the physical channel.

[0092] UE 115 may support, for example, mTRP wireless communications with two or more network entities 105. mTRP communications may be TDM-based or based on simultaneous transmission (e.g., SDM-based or FDM-based). In addition, UE 115 may support PHR for mTRP operation. PHR may indicate how much transmit power is available for UE 115 for scheduled transmission based on maximum transmit power. In some cases, PHR may be an example of a MAC control element (MAC-CE) indicating the clearance between the current UE transmit power and the nominal power or be included in the MAC control element. Network entity 105 may use the power clearance value in PHR to estimate how much uplink bandwidth UE 115 can use for the scheduled transmission of the UE. In some cases, UE 115 may determine type 1 PHR for an activated serving cell based on a reference uplink transmission (e.g., PUSCH transmission). For PUSCH transmission opportunity i on active uplink BWP b of carrier f of serving cell c, UE 115 may calculate type 1 PHR according to equation 1 below.

[0093]

[0094] In Equation 1, UE 115 may calculate the value based on the assumptions that MRP=0 dB, additional MRP (A-MRP)=0 dB, P-MRP=0 dB, and ΔT c = 0dB to calculate the maximum transmit power where MRP may represent the allowed reduction in the maximum transmit power of some physical channels (e.g., in an uplink MIMO system), and ΔT c may represent a closed-loop power control parameter that enables the network entity 105 to adjust the transmit power at the UE 115. In addition, It can represent the nominal transmission power, α b.f.c (j) may represent the power control factor, and It can represent the nominal transmit power of PUSCH. UE 115 can use and parameters (e.g., p0-PUSCH-AlphaSetId=0) to determine and α b,f,c (j), and UE 115 may use the path loss parameter (e.g., pusch-PathlossReferenceRS-Id=0) to obtain the RS with index q d The path loss parameter PL of the reference signal b,f,c (q d ), and l=0. Thus, the virtual PHR may be based on a non-scheduled (e.g., virtual) PUSCH transmission instead of a scheduled PUSCH transmission, such that the virtual PHR is based on some assumptions about parameters associated with the non-scheduled PUSCH transmission (rather than the indicated parameters for the scheduled PUSCH transmission). In addition, using Equation 1, the UE may use a single set of power control parameters for the virtual PHR.

[0095] In some examples, UE 115 may report two PHRs for two TRPs supported by the same serving cell (e.g., in an mTRP system). UE 115 may generate the two PHRs using a single set of power control parameters (e.g., not specific to a TRP), wherein at least one of the PHRs may be a virtual PHR that is not specific to a TRP. In addition, UE 115 may support a unified TCI for mTRP communications, wherein a unified TCI for uplink and downlink may be included with the set of power control parameters, and wherein different TRPs may have different unified TCIs. In some examples, UE 115 may use a unified TCI architecture for indications of multiple downlink and uplink TCI states for mTRP communications.

[0096] Some network entities 105 may configure a set of power control parameters for each serving cell of UE 115 (e.g., via RRC configuration). In some cases, multiple sets of power control parameters may be configured for each serving cell of UE 115 (e.g., in Uplink-powerControl). For example, each TCI state may be associated with a set of power control parameters. Additionally or alternatively, the power control parameters may be configured in a serving cell configuration (e.g., ServingCellConfig). For example, a serving cell configuration may include a list of uplink power control parameters for a corresponding serving cell, wherein the power control parameters may be configured for PUSCH, a physical uplink control channel (PUCCH), a sounding reference signal (SRS), or other transmission types. In addition, different TCI states (e.g., joint or uplink TCI states) may correspond to different uplink power control parameters. Alternatively, if each TCI state lacks an association with a set of power control parameters, the corresponding uplink BWP configuration may be associated with a set of power control parameters. For example, an uplink bandwidth parameter (eg, BWP-UplinkDedicated) may include a set of uplink control parameters.

[0097] In some examples, UE 115 may schedule a signal with a first reference signal resource index q on an active uplink BWPb of carrier f of serving cell c in time slot n. d associated PUSCH. In addition, UE 115 may be configured with one or more PHR modes (e.g., twoPHRMode), which may include Type 1 PHR or Type 2 PHR. Type 1 PHR may indicate the power headroom as the difference between the nominal maximum transmit power of UE 115 and the estimated transmit power of the scheduled uplink transmission per activated serving cell. Type 2 PHR may indicate the power headroom as the difference between the nominal maximum transmit power of the UE and the estimated power of the uplink shared channel transmission or uplink control channel transmission of a particular cell.

[0098] Using the PHR configuration and the scheduled PUSCH, the UE 115 may send a Type 1 PHR to the network entity 105 for use with the second reference signal resource index q dassociated PUSCH repetitions. In some examples, UE 115 may send a Type 1 PHR based on one or more conditions. For example, UE 115 may send a Type 1 PHR based on a first scheduled PUSCH transmission associated with a first reference signal resource index. In some examples, if the UE sends a second scheduled PUSCH transmission associated with a second reference signal resource index in time slot n, UE 115 may send a Type 1 PHR for a second PUSCH transmission associated with the second reference signal resource index, wherein the first scheduled PUSCH transmission and the second scheduled PUSCH transmission may be scheduled for mTRP operation. Alternatively, UE 115 may send a Type 1 PHR for a scheduled PUSCH transmission associated with the first reference signal resource index, and UE 115 may send a Type 1 PHR for a reference (e.g., non-scheduled) PUSCH transmission associated with the second reference signal resource index (e.g., in the example of a virtual PHR). In some cases, if the UE provides a Type 1 PHR for a reference PUSCH transmission associated with a first reference signal resource index, the UE 115 may send a Type 1 PHR for a reference PUSCH transmission associated with a second reference signal resource index.

[0099] The wireless communication system 100 may support TCI-specific virtual PHRs to improve communication between the network entity 105 and the UE 115. In some examples, the network entity 105 may configure the UE 115 with a first set of power control parameters and a second set of power control parameters associated with the first TRP and the second TRP, respectively. Each set of power control parameters may include a PLRS parameter, a nominal power parameter, an α value parameter, a closed loop index parameter, a P-MPR parameter, or a combination thereof. In some cases, at least the second set of power control parameters may be associated with a virtual PHR. The UE 115 may send a message including a first PHR generated by the UE 115 for a first uplink transmission (e.g., a scheduled or non-scheduled PUSCH transmission) using the first set of power control parameters. In addition, the message may include a second PHR generated by the UE 115 for a reference uplink transmission (e.g., a non-scheduled PUSCH transmission) using the second set of power control parameters. Therefore, the UE 115 may send two PHRs to the network entity 105 based on the UE 115 communicating with two TRPs having separate sets of uplink control parameters.

[0100] In some examples, the first uplink transmission and the reference uplink transmission may be associated with respective TCI states, and the network entity 105 may configure these TCI states in the TCI configuration. Thus, the first set of power control parameters and the second set of power control parameters may be associated with respective TCI states. In addition, the network entity 105 may indicate the first set of power control parameters and the second set of power control parameters and their association with the TRP and the corresponding reference signal resource index in the uplink BWP configuration or the serving cell configuration.

[0101] Figure 2 An example of a network architecture 200 (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) supporting TCI-specific virtual PHR according to one or more aspects of the present disclosure is illustrated. The network architecture 200 may illustrate an example for implementing one or more aspects of the wireless communication system 100. The network architecture 200 may include one or more CUs 160-a, which may communicate directly with the core network 130-a via a backhaul communication link 120-a, or indirectly communicate with the core network 130-a through one or more disaggregated network entities 105 (e.g., a near-RT RIC 175-b via an E2 link, or a non-RT RIC 175-a associated with an SMO 180-a (e.g., an SMO framework), or both. The CU 160-a may communicate with one or more DUs 165-a via corresponding midhaul communication links 162-a (e.g., an F1 interface). The DU 165-a may communicate with one or more RUs 170-a via corresponding fronthaul communication links 168-a. The RU 170-a may be associated with a respective coverage area 110-a and may communicate with the UE 115-a via one or more communication links 125-a. In some implementations, the UE 115-a may be served simultaneously by multiple RUs 170-a.

[0102] Each of the network entities 105 of the network architecture 200 (e.g., CU 160-a, DU 165-a, RU 170-a, non-RT RIC 175-a, near-RT RIC 175-b, SMO 180-a, open cloud (O-Cloud) 205, open eNB (O-eNB) 210) may include one or more interfaces or may be coupled to one or more interfaces configured to receive or send signals (e.g., data, information) via a wired or wireless transmission medium. Each network entity 105 or an associated processor (e.g., a controller) that provides instructions to an interface of the network entity 105 may be configured to communicate with one or more of the other network entities 105 via a transmission medium. For example, these network entities 105 may include a wired interface that is configured to receive signals on a wired transmission medium or to send signals to one or more of the other network entities 105 on a wired transmission medium. Additionally or alternatively, the network entity 105 may include a wireless interface, which may include a receiver, a transmitter, or a transceiver (e.g., an RF transceiver) configured to receive signals on a wireless transmission medium, or to send signals to one or more of the other network entities 105 on a wireless transmission medium, or both.

[0103] In some examples, CU 160-a may host one or more higher layer control functions. Such control functions may include RRC, PDCP, SDAP, etc. Each control function may be implemented with an interface configured to communicate signals with other control functions hosted by CU 160-a. CU 160-a may be configured to handle user plane functionality (e.g., CU-UP), control plane functionality (e.g., CU-CP), or a combination thereof. In some examples, CU 160-a 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, CU 160-a may be implemented to communicate with DU 165-a for network control and signaling.

[0104] DU 165-a may correspond to a logical unit that includes one or more functions (e.g., base station functions, RAN functions) for controlling the operation of one or more RUs 170-a. In some examples, DU 165-a may at least partially host one or more of the RLC layer, the MAC layer, and one or more aspects of the PHY layer (e.g., a high PHY layer, such as modules for FEC encoding and decoding, scrambling, modulation and demodulation, etc.), which depends at least in part on functional splits, such as those defined by the Third Generation Partnership Project (3GPP). In some examples, DU 165-a may also host one or more low PHY layers. Each layer may be implemented using an interface that is configured to communicate signals with other layers hosted by DU 165-a or with control functions hosted by CU 160-a.

[0105] In some examples, lower layer functionality may be implemented by one or more RUs 170-a. For example, a RU 170-a controlled by a DU 165-a may correspond to a logical node that hosts RF processing functions or low PHY layer functions (e.g., performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.) or both based at least in part on functional splitting (such as lower layer functional splitting). In such an architecture, RU 170-a may be implemented to handle over-the-air (OTA) communications with one or more UEs 115-a. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with RU 170-a may be controlled by corresponding DU 165-a. In some examples, such a configuration may enable DU 165-a and CU160-a to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0106] The SMO 180-a may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network entities 105. For non-virtualized network entities 105, the SMO 180-a 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 (e.g., an O1 interface). For virtualized network entities 105, the SMO 180-a may be configured to interact with a cloud computing platform (e.g., O-Cloud 205) to perform network entity lifecycle management (e.g., instantiating virtualized network entities 105) via a cloud computing platform interface (e.g., an O2 interface). Such virtualized network entities 105 may include, but are not limited to, CU 160-a, DU 165-a, RU 170-a, and near-RT RIC 175-b. In some specific implementations, the SMO 180-a may communicate (e.g., via an O1 interface) with components configured according to a 4G RAN. Additionally or alternatively, in some implementations, the SMO 180-a may communicate directly with one or more RUs 170-a via an O1 interface. The SMO 180-a may also include a non-RT RIC 175-a configured to support the functionality of the SMO 180-a.

[0107] The non-RT RIC 175-a may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) or machine learning (ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 175-b. The non-RT RIC 175-a may be coupled to or communicate with the near-RT RIC 175-b (e.g., via an A1 interface). The near-RT RIC 175-b 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 on an interface (e.g., via an E2 interface) that connects one or more CUs 160-a, one or more DUs 165-a, or both, and the O-eNB 210 with the near-RT RIC 175-b.

[0108] In some examples, in order to generate an AI / ML model to be deployed in the near-RT RIC 175-b, the non-RT RIC 175-a may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 175-b and may be received from a non-network data source or from a network function at the SMO 180-a or the non-RT RIC 175-a. In some examples, the non-RT RIC 175-a or the near-RT RIC 175-b may be configured to tune RAN behavior or performance. For example, the non-RT RIC 175-a may monitor long-term trends and patterns of performance and employ an AI model or ML model to perform corrective actions through the SMO 180-a (e.g., via reconfiguration of O1) or via the generation of a RAN management policy (e.g., an A1 policy).

[0109] The network architecture 200 may support TCI-specific virtual PHRs to improve communication between the network entity 105 and the UE 115. -a. In some examples, the network entity 105 may configure the UE 115-a with a first set of power control parameters and a second set of power control parameters associated with a first TRP and a second TRP, respectively. Each set of power control parameters may include a PLRS parameter, a nominal power parameter, an α value parameter, a closed-loop index parameter, a P-MPR parameter, or a combination thereof. In some cases, at least the second set of power control parameters may be associated with a virtual PHR. The UE 115-a may send a message including a first PHR generated by the UE 115-a for a first uplink transmission (e.g., a scheduled or non-scheduled PUSCH transmission) using the first set of power control parameters. In addition, the message may include a second PHR generated by the UE 115-a for a reference uplink transmission (e.g., a non-scheduled PUSCH transmission) using the second set of power control parameters. Thus, UE 115-a may send two PHRs to network entity 105 based on UE 115-a communicating with two TRPs having separate sets of uplink control parameters.

[0110] Figure 3 An example of a wireless communication system 300 that supports TCI-specific virtual PHRs according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 300 may implement aspects of the wireless communication system 100, or may be implemented by aspects of the wireless communication system 100. For example, the wireless communication system 300 may include a UE 115-b, a network entity 105-a, and a TRP 305, which may be examples of corresponding devices as described herein. In some examples, the UE 115-b may generate a PHR for one or more uplink transmissions using a first parameter and a second set of parameters corresponding to the corresponding TRP 305.

[0111] The network architecture 200 may support communication between a network entity 105-a and a UE 115-b. For example, the UE 115-b may operate in a multi-TRP mode with a first TRP 305-a and a second TRP 305-b. In some cases, the first TRP 305-a and the second TRP 305-b may be located at the same network entity 105-a. In some cases, the first TRP 305-a and the second TRP 305-b may be located at different network entities 105.

[0112] In some examples, UE 115-b may perform simultaneous communications with a first TRP 305-a and a second TRP 305-b over respective communication links 310, which may be as described herein. Figure 1 An example of the communication link 125 described. The communication link 310 may include a bidirectional link that implements both uplink communication and downlink communication. For example, UE 115-b may use the corresponding communication link 310 to send an uplink signal (such as an uplink control signal or an uplink data signal) to the first TRP 305-a, and TRP 305-a may use the corresponding communication link 310 to send a downlink transmission (such as a downlink control signal or a downlink data signal) to UE 115-b. For example, UE 115-b may use the corresponding communication link 310 to send an uplink signal (such as an uplink control signal or an uplink data signal) to the second TRP 305-b, and TRP305-b may use the corresponding communication link 310 to send a downlink transmission (such as a downlink control signal or a downlink data signal) to UE 115-b. In some examples, different TRPs 305 (e.g., the first TRP 305-a and the second TRP 305-b) may have different TRP identifiers (IDs). In some examples, different TRPs may be identified by association with other IDs, such as a CORESET pool index, a closed loop index, a TCI ID, a TCI group ID, or an SRS resource set ID. In some cases, UE 115-b may operate according to a single frequency network (SFN) configuration such that UE 115-b may receive the same content from each TRP 305 at the same frequency in a synchronized manner.

[0113] To support generating multiple PHRs for TRPs 305 using corresponding sets of power control parameters, UE 115-b may receive a first message 315 indicating a first set of power control parameters associated with a first TRP 305-a and a second set of power control parameters associated with a second TRP 305-b. In some examples, at least the second set of power control parameters may be associated with a virtual PHR such that UE 115-b may generate a PHR associated with a TRP for a reference uplink transmission (e.g., a non-scheduled virtual transmission). In some examples, UE 115-b may receive the first message 315 according to an SFN configuration (e.g., via each TRP 305 at the same frequency).

[0114] In some examples, the first set of power control parameters and the second set of power control parameters may each include a PLRS parameter. The PLRS parameter may enable UE 115-b to generate different PHRs using different path loss values. In some cases, in addition to the PLRS parameter, the first set of power control parameters and the second set of power control parameters may include a nominal power parameter (e.g., P0), an α value parameter (e.g., α b,f,c (j))) (which may correspond to a power control factor, and a closed-loop index parameter (e.g., ΔT c ) (which enables network entity 105-a to adjust the transmit power of UE 115-b). In some examples, in addition to PLRS parameters, nominal power parameters, α value parameters, and closed-loop index parameters, the first set of power control parameters and the second set of power control parameters may include P-MRP parameters, where P-MRP≠0.

[0115] UE 115-b may use a first set of power control parameters corresponding to a first TRP 305-a for a first reference signal resource index (e.g., q d ). In some examples, the first uplink transmission may be an actual PUSCH transmission scheduled for transmission by UE 115-b. In such an example, UE 115-b may generate a first PHR for an actual PUSCH transmission associated with a first reference signal resource index, and UE 115-b may use a second set of power control parameters corresponding to a second TRP 305-b for an actual PUSCH transmission associated with a second reference signal resource index (e.g., q d ) is associated with a reference uplink transmission. The reference uplink transmission may be a PUSCH transmission that is not scheduled for transmission by UE 115-b and may be referred to as a virtual PUSCH transmission. In addition, UE 115-b may obtain PLRS parameters based on the TCI state associated with the reference uplink transmission.

[0116] Alternatively, the first uplink transmission may be a non-scheduled reference uplink transmission. In such a case, because UE 115-b generates PHRs for two reference uplink transmissions, the first PHR and the second PHR may be virtual PHRs, where UE 115-b may obtain the PLRS parameters of each PHR based on the corresponding TCI state corresponding to each reference uplink transmission. UE 115-b may send a second message 320 to network entity 105-a including the first PHR and the second PHR generated by UE 115-b as described herein. In addition, the first PHR and the second PHR may be virtual PHRs generated using the reference uplink transmissions as described herein. Figure 1 Equation 1 described above calculates a Type 1 PHR that indicates a difference between a maximum transmit power of UE 115-b and an estimated power of an uplink transmission (eg, a first uplink transmission or a reference uplink transmission).

[0117] In some cases, the first message 315 may indicate a TCI configuration that identifies that a first uplink transmission (e.g., an actual or reference PUSCH transmission) is associated with a first TCI state and a reference uplink transmission (e.g., a reference PUSCH transmission) is associated with a second TCI state. Thus, the first set of power control parameters or the second set of power control parameters associated with the TCI state related to the first uplink transmission or the reference uplink transmission for the corresponding power headroom calculation may be the TCI state identified in the TCI configuration. For example, the first TCI state or the second TCI state may be indicated in the parameter p0AlphaSetforPUSCH in the TCI configuration.

[0118] Alternatively, if the TCI configuration fails to identify a TCI state corresponding to the first set of power control parameters or the second set of power control parameters, the first message 315 may include an uplink BWP configuration identifying that the first uplink transmission (e.g., an actual or reference PUSCH transmission) is associated with the first set of power control parameters and the reference uplink transmission is associated with the second set of power control parameters. For example, an uplink BWP configuration (e.g., BWP-UplinkDedicated) may indicate a set of power control parameters in an uplink power control information element (e.g., ul-powerControl), wherein the first uplink transmission may be associated with the first uplink power control information element and the reference uplink transmission may be associated with the second uplink power control information element in the uplink BWP configuration.

[0119] Alternatively, if the TCI configuration fails to identify a TCI state corresponding to the first set of power control parameters or the second set of power control parameters, the first message 315 may include a serving cell configuration identifying that a first uplink transmission (e.g., an actual or reference PUSCH transmission) is associated with the first set of power control parameters and a reference uplink transmission is associated with the second set of power control parameters. For example, an uplink power control information element (e.g., ul-powerControl) may be included in a serving cell configuration (e.g., ServingCellConfig), wherein the first uplink transmission may be associated with the uplink power control information element having the lowest value, and the reference uplink transmission may be associated with the uplink power control information element having the second lowest value. Therefore, the network entity 105-a may configure the UE 115-b with the first set of power control parameters and the second set of power control parameters corresponding to the first uplink transmission and the reference uplink transmission, respectively, so that the UE 115-b may generate a first PHR and a second PHR for each TRP 305.

[0120] As described herein, the first set of power control parameters and the second set of power control parameters may each include a PLRS parameter, a nominal power parameter, an α value parameter, a closed-loop index parameter, a P-MRP parameter (e.g., P-MRP≠0), or a combination thereof. For each different set of parameters (e.g., PLRS parameters only, PLRS parameters, nominal power parameters, α value parameters, and closed-loop index parameters, or PLRS parameters, nominal power parameters, α value parameters, closed-loop index parameters, and P-MRP parameters), UE 115-b may generate a first PHR and a second PHR, wherein the first PHR may be a virtual PHR and the second PHR may be a virtual PHR when the first uplink transmission is a reference (e.g., virtual) uplink transmission.

[0121] In some examples, when the first set of parameters and the second set of parameters each include only PLRS parameters or include PLRS parameters, nominal power parameters, α value parameters, and closed-loop index parameters (e.g., each power control parameter described herein except the P-MRP parameter), UE 115-b may assume that MRP=0dB, additional MRP (A-MRP)=0dB, P-MRP=0dB, and ΔT c = 0 (for example, P-MRP is not included in the power control parameter set) and the maximum transmit power is calculated (for example ). Then, UE 115-b may determine the power control parameters included in the first set of uplink control parameters and the second set of uplink control parameters based on the TCI configuration, uplink BWP configuration, or serving cell configuration as described herein. In some cases, when the first set of parameters and the second set of parameters each include only PLRS parameters or include PLRS parameters, nominal power parameters, α value parameters, closed-loop index parameters, and P-MRP parameters, UE 115-b may calculate the maximum transmit power in the same manner, however, the value of the P-MRP value may be non-zero.

[0122] In some examples, the first set of power control parameters may be composed of a first reference signal index q d The first RRC parameter (e.g., pathlossReferenceRS-Id-r17) and the first RRC parameter (e.g., p0AlphaSetforPUSCH-r17) in the associated TCI, and the second set of power control parameters may be indicated by the second reference signal index q d The second RRC parameter (e.g., pathlossReferenceRS-Id-r17) and the second RRC parameter (e.g., p0AlphaSetforPUSCH-r17) in the associated TCI indicate. Each RRC parameter p0AlphaSetforPUSCH-r17 may include a set of parameters, the set of parameters including a nominal power parameter, an alpha value parameter, and a closed loop coefficient parameter, and each RRC parameter pathlossReferenceRS-Id-r17 may include a PLRS parameter. In some examples, the first reference signal index q d The associated first set of power control parameters may be indicated by the first RRC parameter pathlossReferenceRS-Id-r17 and the first RRC parameter p0AlphaSetforPUSCH-r17 in the uplink BWP configuration BWP-UplinkDedicated. d The associated second set of power control parameters may be indicated by a second RRC parameter pathlossReferenceRS-Id-r17 and a second RRC parameter p0AlphaSetforPUSCH-r17 in the uplink BWP configuration BWP-UplinkDedicated. d The associated first set of power control parameters may be indicated by the first RRC parameter pathlossReferenceRS-Id-r17 and the first RRC parameter p0AlphaSetforPUSCH-r17 in the serving cell configuration ServingCellConfig, and the second reference signal index qd The associated second set of power control parameters may be indicated by a second RRC parameter pathlossReferenceRS-Id-r17 and a second RRC parameter p0AlphaSetforPUSCH-r17 in the serving cell configuration ServingCellConfig.

[0123] By using the first set of parameters and the second set of parameters to generate the first PHR and the second PHR as described herein, communication between the UE 115-b and the network entity 105-a may be improved. For example, by communicating the first set of power control parameters and the second set of power control parameters in a TCI configuration, an uplink BWP configuration, or a serving cell configuration, the UE 115-b and the network entity 105-a may reduce latency by more accurately calculating power headroom values ​​for different TRPs 305. Additionally, generating more accurate power headroom values ​​may reduce failed transmissions and improve overall communication between the UE 115-b and the network entity 105-a, among other benefits.

[0124] Figure 4 An example of a process flow 400 for supporting a TCI-specific virtual PHR according to one or more aspects of the present disclosure is illustrated. The process flow 400 may implement aspects of the wireless communication system 100 or 300, or may be implemented by aspects of the wireless communication systems 100 and 300. For example, the process flow 400 may illustrate operations between a UE 115-c and a network entity 105-b (which may be examples of corresponding devices described herein). In the following description of the process flow 400, the operations between the UE 115-c and the network entity 105-b may be sent in an order different from the example order shown, or the operations performed by the UE 115-c and the network entity 105-b may be performed in a different order or at a different time. Some operations may also be omitted from the process flow 400, and other operations may be added to the process flow 400.

[0125] At 405, UE 115-c may receive a first message from network entity 105-b indicating a first set of power control parameters associated with a first TRP and a second set of power control parameters associated with a second TRP, wherein at least the second set of power control parameters is associated with a virtual PHR. For the virtual PHR, UE 115-c may calculate the power headroom using a reference uplink transmission (e.g., a virtual PUSCH transmission) that may not be scheduled for transmission by UE 115-b.
