Description

[0001] This application is a divisional application of the application filed on January 6, 2023, with application number 202080102859.7 and invention title "Path Loss Reference Signal Update for Multiple Beams". Technical Field

[0002] The following relates to wireless communication, including path loss reference signal update for multiple beams. Background Art

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems are capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi-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 Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multi-access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication for multiple communication devices (which may also be referred to as User Equipment (UE)).

[0004] A UE may be configured to send multiple uplink messages to one or more base stations. In some cases, a UE may be configured to send a first uplink message and a second uplink message on a beam. Current techniques for sending multiple uplink messages on a beam may fail to support flexible transmission parameters. Summary of the Invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting path loss reference signal update for multiple beams. Generally, the described techniques reduce latency by configuring power control parameters for a resource set. For example, a User Equipment (UE) may communicate with one or more base stations using multiple resource sets (e.g., multiple beams, multiple links, etc.). The UE may use a first resource set and transmit a first uplink message according to a first transmit power, and use a second resource set and transmit a second uplink message according to a second transmit power.

[0006] For example, a UE may receive a first control message indicating an uplink power control configuration for the UE. The uplink power control configuration may be associated with a power control identifier and a resource set identifier. The UE may receive a second control message scheduling an uplink message for the UE. The second control message may indicate the resource set identifier and the power control identifier for the transmission of the uplink message. The UE may determine a transmit power for the uplink message based on a set of power control parameters corresponding to the resource set identifier and the power control identifier. The UE may use the resource set associated with the resource set identifier and transmit the uplink message according to the determined transmit power.

[0046] In some wireless communication systems, a user equipment (UE) may communicate with a base station via a beam or a set of resources, but the beam may be blocked or of poor quality. The UE may communicate across multiple beams (e.g., across multiple panels of a base station, across multiple base stations, etc.), which may support the use of at least one high-quality beam. In some cases, the UE may be scheduled to have multiple uplink transmission opportunities (e.g., multiple physical uplink control channel transmissions (PUSCH)) corresponding to multiple beams. However, the power control parameters for the uplink transmission may be associated with a specific beam or set of resources, and thus the base station may lack the ability to configure different power control parameters for different resource sets. Additionally, the base station may lack the ability to update the power control parameters (e.g., path loss reference signal, received power level, partial path loss compensation, etc.) for a specific resource set.

[0047] Aspects of the present disclosure provide techniques for handling the transmission of uplink messages according to power control configurations for a resource set. For example, a base station may configure a UE with one or more power control configurations (e.g., one or more sounding reference signal (SRS) resource indicator (SRI) PUSCH power control (SRI-PUSCH-PowerControl) configurations) as part of a resource control procedure (e.g., a radio resource control (RRC) procedure). The power control configuration may include a resource set identifier (e.g., sri-resource-setId) corresponding to a resource set (e.g., a link, a beam, a time period, etc.) and a power control identifier (e.g., sri-PUSCH-PowerControlId) corresponding to a set of uplink power control parameters (e.g., sri-PUSCH-PathlossReferenceRS-Id, sri-P0-PUSCH-AlphaSetId, sri-PUSCH-ClosedLoopIndex, etc.). The base station may send a control message (e.g., downlink control information (DCI)) to the UE, and the control message may indicate several sounding reference signal (SRS) reference sets and the power control configuration corresponding to each SRS resource set.

[0048] Such techniques may include the base station updating a power control parameter (e.g., a PUSCH path loss reference RS ID) through the transmission of a downlink message (e.g., a media access control (MAC) control element (CE)). The power control parameter may be part of a power control configuration associated with a resource set identifier and a power control identifier. Transmitting multiple uplink messages according to multiple power control configurations may reduce system latency and increase data throughput.

[0049] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further described in the context of uplink transmission techniques, transmission parameter update techniques, and process flows. Aspects of the present disclosure are further described and with reference to these figures by means of diagrams of apparatuses, system diagrams, and flowcharts related to path loss reference signal updates for multiple beams.

[0050] Figure 1An example of a wireless communication system 100 that supports path loss reference signal updates for multiple beams in accordance with aspects of the present disclosure is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long-Term Evolution (LTE) network, an enhanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices, or any combination thereof.

[0051] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be devices of different forms or having different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110, and the UEs 115 and the base stations 105 may establish one or more communication links 125 over the coverage area 110. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support the transmission of signals in accordance with one or more radio access technologies.

[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 both at different times. The UEs 115 may be devices of different forms or having different capabilities. In Figure 1 Some example UEs 115 are shown. The UEs 115 described herein are capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), as Figure 1 shown.

[0053] The base stations 105 may communicate with the core network 130, or with each other, or both. For example, the base stations 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate directly (e.g., directly between base stations 105) with each other via the backhaul links 120 (e.g., via X2, Xn, or other interfaces), or indirectly (e.g., via the core network 130) with each other, or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

[0054] One or more of the base stations 105 described herein may include or may be referred to by those skilled in the art as a base station transceiver, radio base station, access point, radio transceiver, Node B, evolved Node B (eNB), next generation Node B, or Gigabit Node B (either of which may be referred to as a gNB), home Node B, home evolved Node B, or some other suitable term.

[0055] The UE 115 may include or may be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, where the "device" may also be referred to as a unit, station, terminal, or client, etc. The UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine type communication (MTC) device, and other examples, which may be implemented in various items such as appliances, or vehicles, meters, etc.

[0056] The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s that can sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc., as Figure 1 shown.

[0057] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP), which 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 the operation of the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0058] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have control signaling for obtaining signaling or coordinating operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and may be placed according to a channel raster for discovery by UE 115. A carrier may operate in an independent mode where UE 115 performs initial acquisition and connection via the carrier, or a carrier may operate in a non-independent mode where a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0059] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from UE 115 to the base station 105 or a downlink transmission from the base station 105 to UE 115. A carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0060] A carrier may be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of determined bandwidths for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication on a specific carrier bandwidth or may be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0061] The signal waveform transmitted on a carrier can be composed of 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 adopting MCM techniques, a resource element can include a symbol period (e.g., the duration of a modulated symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity for communication with UE 115.

[0062] One or more numerologies for a carrier can be supported, where a numerology can include a subcarrier spacing (Δf) and a cyclic prefix. The carrier can be divided into one or more BWPs with the same or different numerologies. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.

[0063] It can be represented in multiples of a basic time unit (which can be referred to as T s = 1 / (Δf max ·N f ) seconds sampling period, where Δf max can represent the maximum supported subcarrier spacing, and N f can represent the maximum supported discrete Fourier transform (DFT) size) to represent the time interval for base station 105 or UE 115. The time interval of communication resources can be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0064] Each frame may include a plurality of consecutively numbered sub - frames or time slots, and each sub - frame or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into sub - frames, and each sub - frame may be further divided into a plurality of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the sub - carrier spacing. Each time slot may include a plurality of symbol periods (e.g., depending on the length of the cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini - time slots each containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f f

[0065] sub - frames, time slots, mini - time slots, or symbols may be the smallest scheduling units (e.g., in the time domain) of the wireless communication system 100 and may be referred to as transmission time intervals (TTIs). 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)).

[0066] Physical channels may be multiplexed on a carrier according to various techniques. For example, time - division multiplexing (TDM) techniques, frequency - division multiplexing (FDM) techniques, or one or more of hybrid TDM - FDM techniques may be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region for a physical control channel (e.g., a control resource set (CORESET)) may be defined by the number of symbol periods and may extend across the system bandwidth of the carrier or a subset of the system bandwidth. 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 a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates arranged in a cascaded manner with one or more aggregation levels. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format having a given payload size. The search space set may include a common search space set configured to send control information to a plurality of UEs 115 and a UE - specific search space set for sending control information to a specific UE 115.

[0067] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" can refer to a logical communication entity for communicating with the base station 105 (e.g., via a carrier), and can be associated with an identifier for distinguishing adjacent cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifier). In some examples, a cell can also refer to the geographic coverage area 110 or a portion of the geographic coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors (such as the capabilities of the base station 105), the range of such a cell can vary from a relatively small area (e.g., a building, a subset of a building) to a relatively large area. For example, a cell can be or include a building, a subset of a building, or an external space between or overlapping with the geographic coverage areas 110, etc.

[0068] Macro cells typically cover a relatively large geographic area (e.g., with a radius of several kilometers) and can allow unrestricted access by UEs 115 having a service subscription with the network provider that supports the macro cell. In contrast to macro cells, small cells can be associated with lower-power base stations 105, and small cells can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UEs 115 having a service subscription with the network provider, or can provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a residence or office). The base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.

[0069] In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that can provide access for different types of devices.

[0070] In some examples, base station 105 may be movable and, thus, provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network where different types of base stations 105 use the same or different radio access technologies to provide coverage for respective geographic coverage areas 110.

[0071] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, base stations 105 may have different frame timings, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for synchronous operation or asynchronous operation.

[0072] Some UEs 115 (such as MTC or IoT devices) may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices integrated with 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 human 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, device monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0073] Some UEs 115 may be configured to operate in a power consumption-reduced mode of operation, e.g., half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than simultaneous transmission and reception). In some examples, the half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for the UE 115 include entering a power-saving deep sleep mode when not participating in active communication, operating on a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type associated with a defined portion or extent (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of the carrier, or external to the carrier.

[0074] 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) or mission-critical communication. The UE 115 may be designed to support ultra-reliability, low latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private communication or group communication and may be supported by one or more mission-critical services such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include prioritization of services, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

[0075] In some examples, the UE 115 is also capable of directly communicating with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0076] 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, vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in a V2X system can communicate with roadside infrastructure (such as a roadside unit), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or perform both operations.

[0077] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which can include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets to or interconnects with an external network (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function unit (UPF)). The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for the UE 115 served by the base station 105 associated with the core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can be connected to the network operator IP services 150. The operator IP services 150 can include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet-switched streaming services.

[0078] Some network devices in the network equipment (e.g., base station 105) can include subcomponents such as an access network entity 140, which can be an example of an access node controller (ANC). Each access network entity 140 can communicate with the UE 115 through one or more other access network transmission entities 145 (which can be referred to as a radio head, a smart radio head, or a transmit / receive point (TRP)). Each access network transmission entity 145 can include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 can be distributed across various network devices (e.g., radio head and ANC) or combined into a single network device (e.g., base station 105).

[0079] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or the decimeter band because the wavelength range is from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may be sufficient to penetrate structures for a macro cell to serve a UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers).

[0080] The wireless communication system 100 may also operate in the super-high frequency (SHF) region using frequency bands from 3 GHz to 30 GHz (also referred to as the centimeter band) or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be even smaller and more closely spaced compared to UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, EHF transmissions may suffer even greater atmospheric attenuation and shorter distances compared to SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the designation of frequency bands across these frequency regions may vary according to country or regulatory authority.

[0081] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ licensed-assisted access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices such as the base station 105 and the UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation in an unlicensed band may be based on a carrier aggregation configuration that combines a component carrier operating in a licensed band (e.g., LAA). Operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, or device-to-device (D2D) transmissions, etc.

[0082] The base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to adopt techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the base station 105 or the UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having a number of rows and columns of antenna ports that the base station 105 may use to support beamforming for communication with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0083] The base station 105 or the UE 115 may use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. For example, a transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0084] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via the antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference while other signals experience destructive interference. Adjustment of the signals transmitted via the antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustment associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0085] As part of the beamforming operation, the base station 105 or the UE 115 can use beam scanning techniques. For example, the base station 105 can use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. The base station 105 can transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions can be used (e.g., by the transmitting device such as the base station 105 or by the receiving device such as the UE 115) to identify the beam direction for subsequent transmissions or receptions performed by the base station 105.

[0086] The base station 105 can transmit some signals (such as data signals associated with a particular receiving device (e.g., UE 115)) in a single beam direction (e.g., the direction associated with a particular receiving device). In some examples, the beam direction associated with a transmission along a single beam direction can be determined based on signals transmitted in one or more beam directions. For example, the UE 115 can receive one or more of the signals transmitted by the base station 105 in different directions and can report to the base station 105 an indication of the signal that has the highest signal quality or otherwise acceptable signal quality received by the UE 115.

[0087] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., by base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 can report feedback indicating precoding weights for one or more beam directions, and the feedback can correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 can transmit reference signals (e.g., cell-specific reference signal (CRS), channel state information reference signal (CSI-RS)) that can be precoded or not precoded. UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 can employ similar techniques to transmit signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., for transmitting data to a receiving device).

[0088] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, a receiving device (e.g., UE 115) can attempt multiple reception configurations (e.g., directional listening). For example, the receiving device can attempt multiple reception directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of an antenna array (e.g., different sets of directional listening weights), or by processing received signals according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of an antenna array (any of the above operations can be referred to as "listening" according to different reception configurations or reception directions). In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). The single reception configuration can be aligned in a beam direction determined based on listening according to different reception configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0089] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, communication at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly for transmission over logical channels. The media access control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide establishment, configuration, and maintenance of the RRC connection between the UE 115 and the base station 105 or the core network 130 to support radio bearers for user plane data. At the physical layer, transport channels can be mapped to physical channels.

[0090] The UE 115 and the base station 105 can support retransmissions of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood that data is correctly received over the communication link 125. HARQ can include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, the device can support HARQ feedback for the same time slot, where the device can provide HARQ feedback for data received in previous symbols in that time slot. In other cases, the device can provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0091] In some cases, the UE 115 can be configured with a resource set for codebook use or non-codebook use (e.g., SRS resource set), and 4 SRS resources in the resource set can be configured for the UE 115. In some cases, the UE 115 can receive DCI from the base station 105, and the DCI can indicate a power control identifier (e.g., sri-PUSCH-PowerControlId). The UE 115 can use the power control identifier as the code point for the SRI field in the DCI. For example, if the SRI field in the DCI is "X", the set of uplink power control parameters (path loss reference signal, P0, alpha, closed-loop index, etc.) for the uplink transmission scheduled by the DCI can correspond to the power control identifier for "X".

[0092] For example, UE 115 may receive a first control message indicating an uplink power control configuration for UE 115. The uplink power control configuration may be associated with a power control identifier and a resource set identifier. UE 115 may receive a second control message scheduling an uplink message for UE 115. The first control message and / or the second control message may be received from base station 105. The second control message may indicate a resource set identifier and a power control identifier for transmission of the uplink message. UE 115 may determine a transmit power for the uplink message based on a set of power control parameters corresponding to the resource set identifier and the power control identifier. UE 115 may use a resource set associated with the resource set identifier and transmit the uplink message according to the determined transmit power.

[0093] Figure 2 An example of a wireless communication system 200 supporting path loss reference signal updates for multiple beams in accordance with aspects of the present disclosure is shown. In some examples, wireless communication system 200 may implement aspects of wireless communication system 100. Wireless communication system 200 may include base stations 105-a and 105-b, which may be examples of base station 105 as described with reference to Figure 1 Each base station 105 may be associated with a plurality of cells and a plurality of coverage areas 110. UE 115-a may communicate with one or more base stations 105 or one or more panels of base station 105.

[0094] UE 115a may be within coverage area 110-a of base station 105-a and coverage area 110-b of base station 105-b. UE115-a may receive a first control message 205 (e.g., an RRC message) from base station 105-a. The first control message 205 may indicate a power control configuration for UE 105-a. In some cases, the first control message 205 may indicate a power control configuration including a resource set identifier (e.g., sri-resource-setId) and a power control identifier (e.g., sri-PUSCH-PowerControlId). The first control message 205 may additionally or alternatively indicate one or more uplink power control parameters (e.g., sri-PUSCH-PathlossReferenceRS-Id, sri-P0-PUSCH-AlphaSetId, sri-PUSCH-ClosedLoopIndex, etc.). UE 105-a may generate one or more tables corresponding to one or more power control configurations based on the first control message 205.

[0095] UE 115-a may receive a second control message 210 (e.g., a DCI message) from the base station 105-a. The second control message 210 may include a resource field 220 indicating one or more SRS resource sets. The SRS resource sets may be associated with codebook usage or non-codebook usage. The second control message 210 may additionally include one or more SRI fields 225. In some cases, the number of SRI fields 225 may correspond to the number of SRS resource sets indicated in the resource field 220. The SRI fields 225 may indicate a resource set identifier and a power control identifier. For example, the resource field 220 may indicate a first resource set and a second resource set, and the SRI field 225-a may correspond to the first resource set because it is the first SRI field 225 of the second control message 210, while the SRI field 225-b may correspond to the second resource set because it is the second SRI field 225 of the second control message 210. The SRI field 225-a may indicate or correspond to a first power control identifier, and the SRI field 225-b may indicate or correspond to a second power control identifier.

[0096] In some cases, the second downlink message 210 may schedule one or more uplink messages (e.g., PUSCH). For example, the second downlink message 210 may contain a resource field 220 indicating the number of resource sets and the corresponding number of SRI fields 225. Each SRI field 225 may indicate a set of power control parameters associated with the resource set among the number of resource sets indicated by the resource field 220. The set of power control parameters indicated by the SRI field 225 may be used to transmit the uplink message using the resource set indicated by the resource field 220.

[0097] UE 115-a may send a set of uplink messages 215 (e.g., one or more PUSCH) to one or more base stations 105. For example, UE 115-a may send a first uplink message 215 to the first panel of the base station 105 and a second uplink message 215 to the second panel of the base station 105. In some additional or alternative cases, UE 115-a may send a first uplink message 215 to the first base station 105 and a second uplink message 215 to the second base station 105. For example, the uplink message 215-a may be sent to the base station 105-a using the first resource set indicated by the SRI field 225-a, and the uplink message 215-b may be sent to the base station 105-b using the second resource set indicated by the SRI field 225-b. In some additional or alternative examples, the transmit power of the uplink message 215-a may be indicated by the SRI field 225-a, and the transmit power of the uplink message 215-b may be indicated by the SRI field 225-b.

[0098] The resource set may correspond to uplink transmission resources. For example, the resource set may correspond to a set of resource blocks, a beam, a link, a set of spatial layers, etc. Sending a first uplink message to a base station using a first resource set and sending a second uplink message to the base station using a second resource set may reduce system latency and / or improve data throughput.

[0099] Figure 3A and 3B FIGS. 301 and 302 illustrate examples of uplink transmission techniques that support path loss reference signal updates for multiple beams in accordance with aspects of the present disclosure. In some examples, uplink transmission techniques 301 and 302 may implement aspects of wireless communication systems 100 or 200. Operations of uplink transmission techniques 301 and 302 may be implemented by a UE 115 or its components as described herein. The UE may receive DCI 305 and send multiple uplink messages 325 using multiple resource sets 330 and in accordance with uplink transmission mode 320. DCI 305 may indicate one or more resource sets 330 and / or power control configurations for one or more uplink messages 325.

[0100] In some cases, DCI 305-a may schedule two or more PUSCH repetitions. The UE may receive DCI 305-a, and DCI 305-a may include a resource field 310-a, an SRI field 315-a, and an SRI field 315-b. In some cases, an uplink message 325 associated with resource set 330-a may be destined for a first base station, and an uplink message 325 associated with resource set 330-b may be destined for a second base station. An uplink message 325 associated with resource set 330-a may correspond to a first beam, a first precoding, a first spatial domain filter, a first spatial relationship information, a first set of power control parameters, or a first power control configuration, and an uplink message 325 associated with resource set 330-b may correspond to a second beam, a second precoding, a second spatial domain filter, a second spatial relationship information, a second set of power control parameters, or a second power control configuration.

[0101] The uplink message 325-a may correspond to the first PUSCH transmission opportunity of the uplink transmission mode 320-a, and the uplink message 325-b may correspond to the second PUSCH transmission opportunity of the uplink transmission mode 320-a. The uplink message 325-c may correspond to the first PUSCH transmission opportunity of the uplink transmission mode 320-b, the uplink message 325-d may correspond to the second PUSCH transmission opportunity of the uplink transmission mode 320-b, the uplink message 325-e may correspond to the third PUSCH transmission opportunity of the uplink transmission mode 320-b, and the uplink message 325-f may correspond to the fourth PUSCH transmission opportunity of the uplink transmission mode 320-b. The uplink message 325-g may correspond to the first PUSCH transmission opportunity of the uplink transmission mode 320-c, the uplink message 325-h may correspond to the second PUSCH transmission opportunity of the uplink transmission mode 320-c, the uplink message 325-i may correspond to the third PUSCH transmission opportunity of the uplink transmission mode 320-c, and the uplink message 325-j may correspond to the fourth PUSCH transmission opportunity of the uplink transmission mode 320-c.

[0102] The UE may identify the uplink transmission mode 320-a based on DCI 305-a, an RRC message, or the UE's configuration. The SRI field 315-a may indicate that the uplink message 325-a corresponds to the resource set 330-a, and the SRI field 315-b may indicate that the uplink message 325-b corresponds to the resource set 330-b. In some cases, the UE may identify the uplink transmission mode 320-b based on DCI 305-a, an RRC message, or the UE's configuration. The SRI field 315-a may indicate that the uplink message 325-c and the uplink message 325-d correspond to the resource set 330-a, and the SRI field 315-b may indicate that the uplink message 325-e and the uplink message 325-f correspond to the resource set 330-b. In some additional or alternative cases, the UE may identify the uplink transmission mode 320-c based on DCI 305-a, an RRC message, or the UE's configuration. The SRI field 315-a may indicate that the uplink message 325-g and the uplink message 325-i correspond to the resource set 330-a, and the SRI field 315-b may indicate that the uplink message 325-h and the uplink message 325-j correspond to the resource set 330-b.

[0103] In some cases, DCI 305-b can schedule FDM PUSCH using different beams. The UE can receive DCI 305-b and use resource sets 330-c and 330-d of uplink transmission mode 320-d to send uplink messages 325-k and 325-l. DCI 305-b can include a resource field 310-b, an SRI field 315-c, and an SRI field 315-d. The SRI field 315-c can indicate that the uplink message 325-k corresponds to the resource set 330-c, and the SRI field 315-d can indicate that the uplink message 325-l corresponds to the resource set 320-d. The resource set 330-c can correspond to a first resource block set, and the resource set 330-d can correspond to a second resource block set.

[0104] In some cases, DCI 305 can be used to schedule PUSCH transmissions for spatial division multiplexing (SDM) using different beams. For example, the resource set 330-c can correspond to a first spatial layer set, and the resource set 330-d can correspond to a second spatial layer set. The resource set 330 can correspond to a beam, a link, a resource block set, a carrier, etc. Sending the uplink message 325 according to the uplink transmission technique 301 or 302 can improve communication reliability. For example, if the link associated with the first resource set 330 is blocked, another link associated with the second resource set 330 may not be blocked, which can improve communication diversity and reliability.

[0105] Figure 4A and 4B FIG. shows examples of transmission parameter update techniques 401 and 402 that support path loss reference signal updates for multiple beams according to aspects of the present disclosure. In some examples, the transmission parameter update techniques 401 and 402 can implement aspects of the wireless communication system 100 or 200. The operations of the transmission parameter update techniques 401 and 402 can be implemented by a UE 115, components of the UE 115, a base station 105, or components of the base station 105 as described herein. The UE can receive a downlink message 405 (e.g., MAC CE) from the base station and send multiple uplink messages based on receiving the downlink message 405. The downlink message 405 can be grouped into multiple octets 415, as indicated by bit indicators 410-a and 410-b.

[0106] The downlink message 405-a may include a serving cell ID 430-a indicating a serving cell and a BWP ID 435-a indicating a bandwidth part (BWP). The downlink message 405-a may include a plurality of reserved bits 420. For example, the downlink message 405-a may include reserved bits 420-a of octet 415-a, reserved bits 420-b of octet 415-b, reserved bits 420-c, reserved bits 420-d, and reserved bits 420-e, as well as reserved bits 420-f and reserved bits 420-g of octet 415-c. In some cases, one or more of the reserved bits 420 may be used to indicate a resource set (e.g., resource-setId, sri-resource-setId, etc.). In some additional or alternative cases, a new field may be added to the downlink message 405-a to indicate a resource set.

[0107] In some cases, a combination of an indication of a resource set and an indication of a power control identifier (e.g., SRI ID440-a, sri-PUSCH-PowerControlId, etc.) may indicate a power control configuration for the resource set. In some cases, the downlink message 405-a may update the power control configuration for the resource set by indicating a parameter of the resource set (e.g., PUSCH path loss reference RS ID 445-a). The UE may update the power control configuration based on the indicated parameter, the power control identifier, and the resource set. In some cases, the UE will send a set of uplink messages (e.g., PUSCH) according to the updated power control configuration. For example, the UE may receive a downlink message (e.g., DCI) indicating the updated power control configuration (e.g., by indicating the resource set and the power control identifier), and the UE may send a set of uplink messages scheduled by the downlink message according to the updated power control configuration.

[0108] The downlink message 405-b may include a serving cell ID 430-b and a BWP ID 435-b that indicate a serving cell. The downlink message 405-b may include a plurality of reserved bits 420. For example, the downlink message 405-b may include reserved bits 420-h of octet 415-d, reserved bits 420-i of octet 415-e, reserved bits 420-j, reserved bits 420-k, and reserved bits 420-l, reserved bits 420-m of octet 415-f, and reserved bits 420-n and reserved bits 420-o of octet 415-g. Octet 415-f may include a bit 425-a, and the bit 425-a may correspond to a reserved bit that indicates whether there is a second power control parameter (e.g., a second PUSCH PL RS ID field) in the downlink message 405-b. In some examples, a bit 425-a indicating a bit value of "1" may indicate that an additional power control parameter is included in the downlink message 405-b, and a bit 425-a indicating a bit value of "0" may indicate that no additional power control parameter is included in the downlink message 405-b. When the bit 425-a indicates that an additional power control parameter is included in the downlink message 405-b, octet 415-g or a second PUSCH path loss reference RS ID 445-c may be included in the downlink message 405-b.

[0109] The downlink message 405-b may support a base station to update a path loss reference signal pair of a power control identifier (e.g., an SRI ID 440-b, an sri-PUSCH-PowerControlId, etc.). The UE may send a plurality of uplink messages (e.g., PUSCH) according to the number of powers indicated in the downlink message 405-b (e.g., the number of transmit powers, a PUSCH path loss reference RS ID 445-b, a PUSCH path loss reference RS ID 445-b, etc.). For example, the UE may receive a downlink message (e.g., DCI) that schedules a plurality of uplink messages corresponding to a power control configuration associated with the same SRI ID 440-b. The UE may send a plurality of uplink messages according to the number of power control parameters included in the downlink message 405-b. For example, the UE may send a first uplink message according to a PUSCH path loss reference RS ID 445-b and a second uplink message according to a PUSCH path loss reference RS ID 445-c. Sending a plurality of uplink messages according to power control parameters (e.g., transmit power, PUSCH power, PUSCH path loss reference RSID, etc.) indicated in a downlink message (e.g., a MAC CE) may reduce system latency and improve reliability.

[0110] Figure 5 illustrates an example of process flow 500 that supports path loss reference signal updates for multiple beams in accordance with aspects of the present disclosure. In some examples, process flow 500 may implement aspects of wireless communication system 100 or 200. Process flow 500 includes UE 115-b, base station 105-c, and base station 105-d, which may be examples of the corresponding devices referred to Figure 1 to 4. UE 115-b may send uplink messages according to multiple resource sets or beams to improve network efficiency and reduce latency. Alternative examples may be implemented, where some steps are performed in a different order than described or not performed at all. In some cases, the steps may include additional features not mentioned below, or additional steps may be added.

[0111] At 505, UE 115b may receive a first control message (e.g., an RRC message) indicating an uplink power control configuration for UE 115-b. The uplink power control configuration may be associated with a power control identifier (e.g., an SRI identifier, sri-PUSCH-PowerControlId, etc.) and a resource set identifier (e.g., resource-set-Id, sri-resource-setId, etc.). The power control identifier, the resource set identifier, or a combination thereof may be associated with a power control configuration (e.g., SRI-PUSCH-PowerControl) for uplink transmission.

[0112] At 510, UE 115-b may receive a second control message (e.g., DCI) scheduling an uplink message for UE 115-b. The second control message may indicate a resource set identifier and a power control identifier for the uplink message.

[0113] At 515, UE 115-b may determine the transmit power for the uplink message based on a set of power control parameters. The set of power control parameters may correspond to the resource set identifier and the power control identifier. In some cases, the combination of the resource set identifier and the power control identifier may correspond to a power control configuration.

[0114] At 520, UE 115-b may use a resource set associated with a resource set identifier and transmit an uplink message according to the determined transmit power. In some cases, UE 115-b may transmit multiple uplink messages. For example, a second control message may indicate two resource sets, and UE 115-b may use the first resource set to transmit a first uplink message to a first panel of base station 105-d and use the second resource set to transmit a second uplink message to a second panel of base station 105-d. In some additional or alternative examples, UE 115-b may use the first resource set to transmit a first uplink message to base station 105-c and use the second resource set to transmit a second uplink message to base station 105-d. In some cases, the transmit power of the first uplink message may be the same as the transmit power of the second uplink message, while in some other cases, the transmit power of the first uplink message may be different from the transmit power of the second uplink message.

[0148] Code 935 may include instructions for implementing aspects of the present disclosure, including instructions for supporting wireless communications. Code 935 may be stored in a non-transitory computer-readable medium (such as system memory or other types of memory). In some cases, code 935 may not be directly executable by processor 940, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein.
