Description

Technical Field

[0001] The following relates to wireless communications at a user equipment (UE), including default power parameters for each transmit / receive point. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, 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 communications for communication devices, which may be referred to as user equipment (UE).

[0003] In some wireless communication systems, a wireless device may use one or more power control parameters to send one or more messages to one or more transmission reception points. However, methods for such power control schemes may be improved / flawed. Summary of the invention

[0048] During wireless communication, a user equipment (UE) may communicate with multiple transmit receive points (TRPs). The multiple TRPs may each be associated with a single transmit configuration indication (TCI) state (also referred to as a unified TCI state), and the UE may receive an indication of such a unified TCI state. In some cases, such a TCI state may specify a set of power control parameters that the UE is to use to communicate with the TRP. However, in some cases, such a unified TCI state associated with the TRP may not include or be associated with a set of power control parameters for the UE to use for uplink communications with the TRP.

[0049] A default power control parameter set corresponding to the TRP may be specified or indicated to the UE, and the UE may use the default power control parameters for beamforming uplink transmissions in multi-TRP operations. For example, different types of transmissions (e.g., physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), sounding reference signal (SRS), or other transmissions) may each have a set of default power control parameters (e.g., PL-RS, P0, α, closed-loop index, other parameters, or any combination thereof). For a given channel or reference signal type, the UE may be provided with multiple power control parameter sets that may correspond to the TRP (e.g., based on or associated with a TRP identifier). In some cases, different power control parameter sets may be introduced for different service types (e.g., eMBB or URLLC) of a given channel or reference signal type. In addition, the UE may receive signaling that may indicate which of multiple default sets is to be used for communication (e.g., in RRC, medium access control-control element (MAC-CE), downlink control information (DCI), or other signaling). In some cases, which of multiple default sets is to be applied may be dynamically indicated in the DCI that schedules or activates the uplink transmission, or configured for semi-persistent uplink transmission, or any combination thereof. Such an indication may include an indication of a link between the TRP and a specific power control parameter set from different power control parameter sets that the UE is to use as the default power control parameter set. Such an indication may be defined or communicated to the UE in various ways (e.g., explicit indication, implicit indication through association with common parameters such as the TRP ID or other parameters, a common index value, other approaches as described herein, or any combination thereof) through a link between the TCI state and the power control parameter set to be used. In this way, in the absence of explicitly provided power control parameters for the TCI state associated with the TRP in multi-TRP (mTRP) operation, the UE can use the default power control parameter set to communicate with the TRP.

[0050] Various aspects of the present disclosure are first described in the context of a wireless communication system. Various aspects of the present disclosure are then described in the context of a wireless communication system and process flow. Various aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to default power parameters for each transmit / receive point.

[0051] Figure 1An example of a wireless communication system 100 supporting a default power parameter for each transmission reception point 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.

[0052] 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, among other nomenclature. 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) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0053] 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 illustrated in FIG. 1. The UEs 115 described herein may be capable of communicating with various types of devices such as Figure 1 Other UEs 115 or network entities 105 are shown communicating.

[0054] 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.

[0055] In some examples, the network entities 105 may communicate with the core network 130, or communicate with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication 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 through the backhaul communication link 120 (e.g., according to X2, Xn or other interface protocols) directly (e.g., directly between each network entity 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 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 .

[0056] 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, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0057] 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)).

[0058] 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, or 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 can be within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 can be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 can 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 that communicate over those communication links.

[0059] 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 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 donor entities or IAB donors. 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 donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) 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 coupled IAB donor's DU 165. 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.

[0060] For example, an access network (AN) or RAN may include an access node (e.g., an IAB donor), communications between an IAB node 104, and one or more UEs 115. The IAB donor may facilitate connectivity 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 donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor 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, 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., CU 160 associated with an alternative IAB donor) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0061] 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 donor may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB donor may relay the UE's transmission through one or more other IAB nodes 104). Additionally or alternatively, the IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104, depending on the relay chain or configuration of the AN. 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 to the child IAB node 104 or the UE 115.

[0062] For example, the IAB node 104 may be referred to as a parent node that supports child IAB node communications and as a child node associated with an IAB donor. The IAB donor may include a CU 160 having a wired or wireless connection to the core network 130 (e.g., a backhaul communication link 120), and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB host may relay transmissions to the UE 115 via the IAB node 104, and may directly signal the transmissions to the UE 115. The CU 160 of the IAB donor may signal the IAB node 104 that a communication link is established via an F1 interface, and the IAB node 104 may schedule transmissions (e.g., transmissions relayed from the IAB donor to the UE 115) via the DU 165. That is, data may be relayed to and from the IAB node 104 via signaling via 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 donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0063] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support the default power parameters for each transmit / receive point 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).

[0064] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other 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.

[0065] 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, or relay base stations, etc. Figure 1shown.

[0066] 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 physical layer structure defined for supporting 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 bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier 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 these devices 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 a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0067] 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 made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0068] The communication link 125 shown in the wireless communication system 100 may include 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 downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry downlink communications and uplink communications (e.g., in TDD mode).

[0069] 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 the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths of carriers of a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). A device of the wireless communication system 100 (e.g., a network entity 105, a UE 115, or both) may have a hardware configuration that supports communication over a particular carrier bandwidth, or may be configured to support communication over 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 the carrier bandwidth.

[0070] The signal waveform transmitted by 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 symbol period (e.g., the duration of a modulation symbol) and a resource of a subcarrier, in which case the symbol period and the 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 of 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 or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

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

[0072] 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).

[0073] 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, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into multiple micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0074] A subframe, a time slot, a mini-time 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 transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0075] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier using, for example, 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)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region to obtain 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 a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0076] 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., via a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other cell identifier) ​​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 smaller areas (e.g., structures, subsets of structures) to larger areas. 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, and the like.

[0077] 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 service subscriptions with a network provider that supports the macro cell. Small cells may be associated with lower power network entities 105 (e.g., lower power base stations 140) than macro cells, and small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with small cells (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.

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

[0079] In some examples, 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.

[0080] 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 synchronous or asynchronous operation.

[0081] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may allow automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0082] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication may be performed with a reduced peak rate. Other energy-saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating over a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0083] The wireless communication system 100 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). 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 or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

[0084] In some examples, a UE 115 may be able to communicate directly with other UEs 115 over 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 of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. 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 performed between UEs 115 without involving network entity 105 .

[0085] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units) using vehicle-to-network (V2N) communications, or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170), or both.

[0086] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of 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 through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of 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.

[0087] 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). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength ranges from about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services 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.

[0088] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also known as a centimeter band) or in an extremely high frequency (EHF) region of a spectrum (e.g., from 30 GHz to 300 GHz) (also known as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between a UE 115 and a network entity 105 (e.g., a base station 140, RU170), and the EHF antenna of the corresponding device may be smaller and closer than the UHF antenna. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may vary by country or regulatory agency.

[0089] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band, such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed RF spectrum band, devices such as the network entity 105 and the UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating in a licensed band. Operations in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0090] 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 in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, 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 collection of multiple 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 may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0091] 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 a technology may be referred to as spatial multiplexing. The multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the 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) and multi-user MIMO (MU-MIMO), in which multiple spatial layers are sent to the same receiving device and in which multiple spatial layers are sent to multiple devices.

[0092] 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 conveyed via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed 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 these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0093] 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.

[0094] 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.

[0095] 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 a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (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., a multi-panel codebook, a linear combination codebook, a 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).

[0096] 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).

[0097] 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 through logical channels. The MAC layer can perform priority processing and multiplexing of logical channels into 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 that supports the radio bearer of 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.

[0098] UE 115 and network entity 105 may support retransmission of data to increase the likelihood of data being successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data through a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In some other examples, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0099] In some implementations, the UE 115 and the network entity 105 may support one or more signaling or configuration-based mechanisms according to which the UE 115 and the network entity 105 may operate in mTRP operation using one or more default power control parameter sets. For example, the UE 115 may communicate with multiple TRPs, and the UE 115 may be provided with multiple default power control parameter sets (e.g., for one or more given channels or reference signal types) that may correspond to the TRPs (e.g., based on or associated with TRP identifiers). The UE 115 may determine or select the default power control parameter set based on a linkage between a TCI state communicated or indicated to the UE 115 and the default power control parameter set, and the linkage may be communicated or indicated in various ways (e.g., an explicit indication, an implicit indication through an association with a common parameter such as a TRP ID or other parameter, a common index value, other approaches as described herein, or any combination thereof).

[0100] Figure 2An example of a wireless communication system 200 that supports a default power parameter for each transmission and reception point according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may include a UE 115-a, which may be related to Figure 1 An example of a UE 115 is discussed. The wireless communication system 200 may include a first TRP 220 and a second TRP 225.

[0101] During wireless communication, UE 115-a may communicate with one or more TRPs, such as first TRP 220 and second TRP 225. UE 115-a may communicate with first TRP 220 and second TRP 225 via communication beam 230. UE 115-a, first TRP 220, and second TRP 225 may employ one or more communication beams 230 to communicate with wireless devices, and may select one or more communication beams 230 to communicate with specific devices.

[0102] In order to communicate with the first TRP 220 and the second TRP 225, the UE 115-a may employ one or more strategies for communicating with both the first TRP 220 and the second TRP 225. For example, the UE 115-a may employ spatial domain multiplexing (SDM). In SDM, the UE 115-a may use different communication beams 230 to communicate with the first TRP 220 and the second TRP 225, thereby spatially separating these communications. The UE 115-a may employ frequency domain multiplexing (FDM), wherein different frequency resources may be used to communicate with the first TRP 220 and the second TRP 225. The UE 115-a may employ the use of time domain multiplexing (TDM), wherein different time resources may be used to communicate with the first TRP 220 and the second TRP 225. In some examples involving TDM, UE 115-a may participate in round-robin mapping (e.g., where UE 115-a may communicate in a round-robin manner on time resources allocated to multiple TRPs) or sequential mapping (e.g., where UE 115-a may communicate in a sequential manner on time resources).

[0103] Because the first TRP 220 and the second TRP 225 may be located at different locations and the UE 115-a may be mobile, the channel conditions between the UE 115-a and the first TRP 220 may be different from the channel conditions between the UE 115-a and the second TRP 225. For example, there may be different obstacles, noise, or interference. Therefore, the UE 115-a may adopt power control parameters to adjust the transmit power used for communication with the first TRP 220 and the second TRP 225. In some cases, such power control parameters may be provided to the UE 115-a (e.g., from a network entity). However, in some cases, the selected uplink TCI state associated with the TRP ID may not indicate which power control parameter set the UE 115-a is to use for one or more uplink transmissions to the TRP corresponding to the TRP ID, and some methods of wireless communication may not indicate any default power control parameters for use by the UE 115-a in such cases.

[0104] A default set of power control parameters corresponding to a TRP (e.g., a first TRP 220, a second TRP 225, or both) may be specified or indicated to a UE 115-a and the UE may use the default power control parameters for beamformed uplink transmissions in multi-TRP operation. For example, a UE 115-a may receive a first control message (e.g., RRC, MAC-CE, DCI, or other control signaling) that may include one or more code points, and each code point may be mapped to one or more TCI states. The UE 115-a may receive a second control message (e.g., RRC, MAC-CE, DCI, or other control signaling) that may include an indication of a code point that may match one of the code points provided in the first control message, thereby indicating a first TCI state and / or a second TCI state that the UE 115-a is to use to communicate with the first TRP 220 and / or the second TRP 225. UE 115-a may also receive a third control message (e.g., RRC, MAC-CE, DCI, or other control signaling) that includes a grant for an uplink transmission. If the uplink transmission is scheduled to be associated with the first TRP 220, UE 115-a may send uplink communications to the first TRP 220 using the first TCI and may do so using a first set of power control parameters. If the uplink transmission is scheduled to be associated with the second TRP 225, UE 115-a may send uplink communications to the second TRP 225 using the second TCI and may do so using a second set of power control parameters. If the uplink transmission is scheduled to be associated with both the first TRP 220 and the second TRP 225, UE 115-a may send uplink communications to both the first TRP 220 and the second TRP 225 using the first TCI and the second TCI and may do so using a first set of power control parameters and a second set of power control parameters, respectively. UE 115-a may identify, determine or select a first set of power control parameters based on a link, association or mapping between the first TRP 220 and the first set of power control parameters. Similarly, UE 115-a may identify, determine or select a second set of power control parameters based on a link, association or mapping between the second TRP 225 and the second set of power control parameters. In this way, UE 115-a may be provided with a default set of power control parameters for communicating with multiple TRPs. In some aspects, different TRPs may be associated with different other identifiers. For example, different TRPs may correspond to different CORESET pool indexes, different closed-loop indexes, different TCIs or TCI group IDs, or different SRS resource set IDs. The TRP ID associated with a channel or reference signal may be determined by other identifiers associated with the channel or reference signal.

[0105] In some examples, UE 115-a, one or more network entities, the first TRP 220, the second TRP 225, or any combination thereof may perform operations associated with one or more unified TCIs. Such unified TCIs may be of different types, sometimes designated as types 1 to 6. For example, a type 1 unified TCI may include a joint downlink and uplink common TCI state, which may indicate a common beam for at least one downlink channel, reference signal, or both and at least one uplink channel, reference signal, or both. A type 2 unified TCI may include a separate downlink common TCI state to indicate a common beam for more than one downlink channel, reference signal, or both. A type 3 unified TCI may include a separate uplink common TCI state to indicate a common beam for more than one uplink channel, reference signal, or both. A type 4 unified TCI may include a separate downlink single channel or reference signal TCI state (or both) to indicate a beam for a single downlink channel, reference signal, or both. Type 5 unified TCI may include separate uplink single channel or reference signal TCI states (or both) to indicate the beam used for a single uplink channel, reference signal, or both. Type 6 unified TCI may include uplink spatial relationship information (SRI) to indicate the beam used for a single uplink channel or reference signal. Any (single or multiple) or all of these unified TCI states are employed in conjunction with the approaches described herein. In some examples of the subject matter described herein, uplink applicable TCI may include uplink and joint TCI.

[0106] Figure 3 An example of a process flow 300 for supporting default power parameters for each transmit receive point in accordance with one or more aspects of the present disclosure is illustrated. The process flow 300 may include or involve various processes for a network entity 105-b and a UE 115-b to engage in wireless communications. The process flow 300 may describe subject matter related to unified TCI indication as it relates to providing a UE 115-b with default power parameters for communicating with one or more TRPs.

[0107] UE 115-b may receive RRC 320 (e.g., from network entity 105-b). RRC 320 may include one or more configurations that may be associated with a TCI list, mTRP operation, or both. For example, UE 115-a may receive RRC 320 that may include a TCI list, one or more of which may be selected for communicating with one or more TRPs. In addition, such TCIs in the TCI list may be used by UE 115-b to select, determine, or identify a default set of power parameters for communicating with a TRP.

[0108] UE 115-b may receive (e.g., from network entity 105-b) a MAC-CE 325. MAC-CE 325 may include a TCI activation or indication, which may indicate one or more code points that may be associated with some or all TCI states included in a TCI state list in RRC 320. In some examples, UE 115-b may send an acknowledgment (ACK) 330 in response to receiving MAC-CE 325.

[0109] UE 115-b may receive DCI 335 (e.g., from network entity 105-b). DCI 335 may include a unified TCI indication that may indicate a code point (e.g., included in one or more code points in MAC-CE 325). The code point may be mapped to one or more TCI states or TCI state identifiers, and UE 115-b may determine, select, or identify that UE 115-b is to use the TCI state mapped in the code point to communicate with the TRP. Additionally or alternatively, such TCI state may be used by UE 115-b to select, determine, or identify at least one power parameter set for communicating with the TRP. For example, UE 115-b may determine or identify that the selected TCI state is associated with one or more default power parameter sets, which may also be associated with the TRP with which UE 115-a may be communicating. In some examples, UE 115-b may send ACK 340 to confirm receipt of DCI 335. In some examples, UE 115-b may receive DCI 345 or other DCI that may schedule one or more transmissions (e.g., uplink transmissions) of channels or reference signals associated with single TRP (sTRP) or mTRP operation. The one or more transmissions may be transmissions to be transmitted using a default set of power parameters determined, identified, selected, or obtained in accordance with the subject matter described herein.

[0110] In some examples, UE 115-b may send one or more uplink transmissions 350 (e.g., which may have been scheduled by DCI 335 or one or more other DCIs). In some examples, such uplink transmissions 350 may be sent using a default set of power parameters determined, identified, selected, or obtained according to the subject matter described herein.

[0111] Figure 4 An example of a process flow 400 for supporting default power parameters for each transmission and reception point according to one or more aspects of the present disclosure is illustrated. The process flow 400 may be implemented with reference to Figures 1 to 3 The process flow 400 may include a network entity 105-c, a UE 115-c, a first TRP 220-a, and a first TRP 220, which may be as described in reference Figures 1 to 3 Examples of similarly named components described.

[0112] In the following description of the process flow 400, the operations between the network entity 105-c, the UE 115-c, the first TRP 220-a, and the first TRP 220 may be performed in a different order or at a different time. Some operations may also be excluded from the process flow 400, or other operations may be added. Although the network entity 105-c, the UE 115-c, the first TRP 220-a, and the first TRP 220 are shown as performing the operations of the process flow 400, some aspects of some operations may also be performed by other elements of the process flow 400 or by elements not depicted in the process flow, or any combination thereof.

[0113] At 420, the UE 115-c may receive control signaling indicating a transmit configuration indication state list corresponding to multiple transmission reception point operations and multiple power control parameter sets, and the transmit configuration indication state list may include multiple transmit configuration indication states.

[0114] At 425 , the UE 115 - c may receive a first control message indicating a plurality of codepoints and a plurality of transmit configurations indicating a status to each codepoint.

[0115] At 430, UE 115-c may receive a second control message including an indication of a codepoint from the plurality of codepoints. In some examples, the codepoint may indicate a first transmit configuration indication state from a plurality of transmit configuration indication states for communicating with a first transmit receiving point (e.g., a first TRP 220-a). In some examples, the codepoint may indicate a second transmit configuration indication state from a plurality of transmit configuration indication states for communicating with a second transmit receiving point (e.g., a second TRP 225-a). In some examples, the codepoint may indicate a first transmit configuration indication state and a second transmit configuration indication state from a plurality of transmit configuration indication states for communicating with a first transmit receiving point and a second transmit receiving point (e.g., a first TRP 220-a, a second TRP 225-a), respectively.

[0116] In some examples where UE 115-c is provided with multiple sets of power control parameters corresponding to the same TRP or TRP identifier, a second control message (e.g., which may be a DCI) may dynamically indicate which of the multiple sets may be applied. The second control message may schedule or activate uplink transmissions, or may be configured for persistent or semi-persistent uplink transmissions.

[0117] At 435, the UE 115-c may receive a third control message including a grant for scheduling transmission of uplink communications. In some examples, the third control message may schedule transmissions to the first transmission reception point 220-a. In some examples, the third control message may schedule transmissions to the second transmission reception point 225-a. In some examples, the third control message may schedule transmissions to the first transmission reception point 220-a and to the second transmission reception point 225-a. In some examples, the network entity 105-c may cause at least one or both of the TRPs 220-a, 225-a to transmit one or more of the transmissions described at 420, 425, 430, and 435, or may cause different devices to transmit one or more of these transmissions. The UE 115-c may determine or select a TCI for uplink transmissions to the transmission reception point based on the second control message and / or the third control message.

[0118] At 440, UE 115-c may send uplink communications to a first transmit reception point (e.g., first TRP 220-a) using a first transmit configuration indication state according to a first set of power control parameters among a plurality of power control parameters, and at 445, UE 115-c may send uplink communications to a second transmit reception point (e.g., second TRP 225-a) using a second transmit configuration indication state according to a second set of power control parameters among a plurality of power control parameters. In some examples, the first set of power control parameters may be linked to the first transmit reception point (e.g., first TRP 220-a) and the second set of power control parameters may be linked to the second transmit reception point (e.g., second TRP 225-a). If the uplink communications at 440 or 445 are pre-configured periodic or semi-persistent transmissions, UE 115-c may not receive the third control message.

[0119] In some examples, a power control parameter set may be associated with a signal or transmission type for a TRP (e.g., a PUSCH transmission, a PUCCH transmission, an SRS transmission, other transmissions, or any combination thereof). For example, there may be one power control parameter set associated with a PUSCH transmission for a TRP, and another power control parameter set associated with a PUCCH transmission for a TRP. The power control parameter set (or other power control parameter sets) may include parameters such as a path loss reference signal identifier that may indicate a path loss reference signal, P0 that may be an initial power control parameter (e.g., a target signal to interference plus noise ratio (SINR) for power control), α that may be a path loss compensation factor, and a closed-loop power control parameter. In some examples, for a given uplink channel or reference signal type, multiple default power control parameter sets corresponding to the same TRP or TRP identifier may be introduced. In some examples, such multiple default power control parameter sets may be introduced for different uplink service types (e.g., eMMB, URLLC, or other service types) for a given uplink channel or reference signal type for a TRP.

[0120] In some aspects, the UE 115-c may process control signaling, a first control message, or a second control message indicating a link between a transmit reception point and a set of power control parameters in a plurality of power control parameters. In some examples, the UE 115-c may process control signaling indicating a link between an identifier of a set of power control parameters in a plurality of power control parameters and a transmit configuration indication state in a plurality of transmit configuration indication states. In some examples, the control signaling may be radio resource control signaling.

[0121] In some examples, UE 115-c may process a first control message indicating a link between an identifier of a first set of power control parameters in a plurality of power control parameters and a first transmit configuration indication state in a plurality of transmit configuration indication states. In some examples, the first control message may include a medium access control control element.

[0122] In some examples, UE 115-c may process a second control message indicating a link between an identifier of a first set of power control parameters in a plurality of power control parameters and a first transmit configuration indication state in a plurality of transmit configuration indication states. In some examples, the second control message may include downlink control information.

[0123] In some examples, UE 115-c may identify that both the first transmit configuration indication state and the first set of power control parameters in the plurality of power control parameters are associated with a communication parameter identifier. In some examples, the communication parameter identifier may include an identifier associated with a first transmit reception point (e.g., a first TRP 220-a), a control resource set pool index, a transmit configuration indication identifier, a beam group identifier, a channel identifier, a reference signal identifier, a resource group identifier, a transmit routing information field order index, a sounding reference signal resource set identifier, a sounding reference signal resource set order index, a default power control parameter identifier, or any combination thereof.

[0124] In some examples, UE 115-c may match an index associated with a first transmit configuration indication state among multiple transmit configuration indication states and an index associated with a first set of power control parameters among multiple power control parameters, where the two indexes include a common value.

[0125] In some examples, the power control parameter set may correspond to a traffic type associated with uplink communications. For example, the traffic type may be an eMMB traffic type, a URLLC traffic type, or another traffic type. For example, there may be one power control parameter set associated with eMMB transmissions for a TRP and another power control parameter set associated with URLLC transmissions for a TRP.

[0126] As described herein, an association of one or more default power control parameter sets with an uplink applicable TCI selected for uplink transmission may be established in various ways. In some examples, a linked default power control parameter set or TCI may be indicated in the configuration of the other. For example, an identifier of a linked default power control parameter set may be indicated or configured per TCI state identifier (e.g., as indicated in a TCI state information element included in a DCI, MAC-CE, RRC signaling, etc.). Additionally or alternatively, an identifier of a linked TCI may be indicated or configured per default power control parameter set (e.g., as indicated in a TCI state information element included in a DCI, MAC-CE, RRC signaling, etc.).

[0127] In some examples, the linkage between the default power parameter set and the TCI may be dynamically indicated in control signaling or a message (e.g., a MAC-CE or a DCI). For example, the linkage may be indicated in control signaling, a first control message, a second control message, a third control message, or any combination thereof. For example, an activation MAC-CE (of which the first control message may be an example) may indicate an identifier of a default power control parameter set to be used by UE 115-c for uplink transmissions. In an example, an activation control message (e.g., a MAC-CE) may indicate one or more default power control parameter set identifiers per activated TCI state.

[0128] In some examples, the link between the default power parameter set and the TCI may be indicated by an explicit or implicit TRP identifier. For example, one or more or each selected unified TCI or TCI state may be mapped to an expected TRP identifier (e.g., an explicit TRP identifier), and each default power control parameter set may also be mapped to an expected TRP identifier (e.g., an explicit TRP identifier). Additionally or alternatively, one or more selected unified TCIs or TCI states and each default power control parameter set may be mapped to another parameter (e.g., the parameter may be an implicit TRP identifier). Examples of such other parameters may include CORESETPoolIndex, TCI / beam group identifier, channel, reference signal / resource group identifier, SRI field order index, SRS resource set identifier / order index, default power control parameter set identifier, or any combination thereof. For example, an uplink applicable TCI state or a default power control parameter set may be associated with a first SRS resource set or a second SRS resource set that may be mapped to TRP identifier 1 or 2.

[0129] In some examples, the link between the default power parameter set and the TCI can be implicitly determined by the sequential indexing of the TCI and the default power parameter set. For example, the first indexed TCI in the TCI code point can be mapped to the first indexed power control parameter set, and the second indexed TCI in the TCI code point can be mapped to the second indexed power control parameter set, and so on.

[0130] Figure 5 A block diagram 500 of a device 505 supporting default power parameters for each transmit-receive point according to one or more aspects of the present disclosure is shown. The device 505 may be an example of aspects of the UE 115 as described herein. The device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. The device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0131] The receiver 510 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with default power parameters for each transmit / receive point). The information may be communicated to other components of the device 505. The receiver 510 may utilize a single antenna or a collection of multiple antennas.

[0132] The transmitter 515 may provide means for transmitting signals generated by other components of the device 505. For example, the transmitter 515 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with default power parameters for each transmit / receive point). In some examples, the transmitter 515 may be co-located with the receiver 510 in a transceiver module. The transmitter 515 may utilize a single antenna or a collection of multiple antennas.

[0133] The communication manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or various components thereof, may be examples of means for performing various aspects of the default power parameters for each transmit-receive point described herein. For example, the communication manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.

[0134] In some examples, the communication manager 520, the receiver 510, the transmitter 515, or various combinations or components thereof may be implemented in hardware (e.g., in a communication management circuit). The hardware may include a processor, a digital signal processor (DSP), a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic, discrete hardware components, or any combination thereof that is configured to or otherwise supports components for performing the functions described in the present disclosure. In some examples, the processor and a memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in the memory by the processor).

[0135] Additionally or alternatively, in some examples, the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in code executed by a processor, the functionality of the communication manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be performed by a general purpose processor (e.g., configured as or otherwise supporting components for performing the functions described in the present disclosure), a DSP, a CPU, an ASIC, an FPGA, a microcontroller, or any combination of these or other programmable logic devices.

[0136] In some examples, communication manager 520 may be configured to perform various operations (e.g., receive, obtain, monitor, output, send) using or otherwise cooperating with receiver 510, transmitter 515, or both. For example, communication manager 520 may receive information from receiver 510, transmit information to transmitter 515, or be integrated in conjunction with receiver 510, transmitter 515, or both to obtain information, output information, or perform various other operations as described herein.

[0137] According to the examples disclosed herein, the communication manager 520 may support wireless communication at the UE. For example, the communication manager 520 may be configured to or otherwise support a component for receiving a first control message, the first control message indicating a set of multiple code points and a set of multiple transmission configuration indication states. The communication manager 520 may be configured to or otherwise support a component for receiving a second control message, the second control message including a grant for scheduling uplink communication to a first transmission reception point and an indication of a code point in the set of multiple code points, the code point indicating a first transmission configuration indication state in the set of multiple transmission configuration indication states for communicating with the first transmission reception point. The communication manager 520 may be configured to or otherwise support a component for sending uplink communication to the first transmission reception point using the first transmission configuration indication state according to a first set of power control parameters in a set of multiple power control parameters, wherein the link between the first set of power control parameters and the first transmission reception point is indicated in the first control message, the second control message, or the control signaling.
