Description

Technical Field

[0001] The following discussion relates to wireless communication, including path loss reference signal updates for multiple beams. Background Technology

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)).

[0003] The UE can be configured to send multiple uplink messages to one or more base stations. In some cases, the UE can 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 not support flexible transmission parameters. Summary of the Invention

[0004] The described technology relates to improved methods, systems, devices, and apparatuses for supporting path loss reference signal updates for multiple beams. In summary, the described technology reduces latency by configuring power control parameters for resource sets. For example, a user equipment (UE) can communicate with one or more base stations using multiple resource sets (e.g., multiple beams, multiple links, etc.). The UE can 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.

[0005] For example, the 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 uplink messages for the UE. The second control message may indicate a resource set identifier and a power control identifier for the transmission of uplink messages. The UE may determine the transmit power for the uplink messages based on a power control parameter set 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 uplink messages according to the determined transmit power.

[0045] In some wireless communication systems, user equipment (UE) can communicate with a base station via a beam or resource set, but the beam may be blocked or of poor quality. The UE can communicate across multiple beams (e.g., across multiple panels of a base station, across multiple base stations, etc.), which can support the use of at least one high-quality beam. In some cases, the UE can be scheduled with multiple uplink transmission opportunities corresponding to multiple beams (e.g., multiple physical uplink control channel (PUSCH) transmissions). However, the power control parameters for uplink transmissions can be associated with a specific beam or resource set, so 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 power control parameters for a specific resource set (e.g., path loss reference signal, received power level, partial path loss compensation, etc.).

[0046] Various aspects of this disclosure provide techniques for processing uplink message transmission based on power control configurations for resource sets. For example, a base station may configure a UE with one or more power control configurations (e.g., one or more 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., link, beam, 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 can send control messages (e.g., downlink control information (DCI)) to the UE, and the control messages can indicate several sounding reference signal (SRS) reference sets and the power control configuration corresponding to each SRS resource set.

[0047] Such techniques may include base stations updating power control parameters (e.g., PUSCH path loss reference RS ID) via the transmission of downlink messages (e.g., Media Access Control (MAC) control elements (CE)). Power control parameters may be part of a power control configuration associated with a resource set identifier and a power control identifier. Sending multiple uplink messages based on multiple power control configurations can reduce system latency and increase data throughput.

[0048] The various aspects of this disclosure are first described in the context of a wireless communication system. These aspects are further described in the context of uplink transmission techniques, transmission parameter update techniques, and process flows. The various aspects of this disclosure are further described, and with reference to, apparatus diagrams, system diagrams, and flowcharts relating to path loss reference signal updates for multiple beams.

[0049] Figure 1Examples of a wireless communication system 100 supporting path loss reference signal updates for multiple beams are illustrated according to various aspects of this disclosure. 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 improved LTE (LTE-A) network, an LTE-APro 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.

[0050] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 over the coverage area 110. The coverage area 110 can be an example of a geographical area over which base stations 105 and UE 115 can support signal transmission according to one or more radio access technologies.

[0051] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown in the image.

[0052] Base station 105 can communicate with core network 130, communicate with each other, or perform both of the above operations. For example, base station 105 can interface with core network 130 through one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) through backhaul links 120 (e.g., via X2, Xn, or other interfaces), or perform both of the above operations. In some examples, backhaul link 120 can be or includes one or more radio links.

[0053] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or some other suitable term.

[0054] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or 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, 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, vehicles, meters, etc.

[0055] The UE 115 described in this document can communicate with various types of devices, such as other UE 115s that can sometimes act as repeaters, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown in the image.

[0056] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of a radio frequency 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-APro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0057] In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate operations for other carriers. The 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 positioned according to a channel grid for discovery by UE 115. The carrier may operate in standalone mode, where UE 115 performs initial acquisition and connection via the carrier, or the carrier may operate in non-standalone mode, where different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.

[0058] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The 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).

[0059] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of defined bandwidths of a carrier used for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication on a specific carrier bandwidth, or can be configured to support communication on one carrier bandwidth in 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 can be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0060] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Extended OFDM (DFT-S-OFDM). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and 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 UE 115 receives 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, temporal 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 used for communication with UE 115.

[0061] One or more digital schemes (numerologies) can be supported for a carrier, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different digital schemes. 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.

[0062] It can be expressed in a basic unit of time (which can be, for example, referred to as T). s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized based on 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).

[0063] 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 (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots 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 (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0064] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0065] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control regions for control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner with one or more aggregation levels. The aggregation level for control channel candidates can refer to the number 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 set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set used to send control information to a specific UE 115.

[0066] Each base station 105 may 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" may refer to a logical communication entity used (e.g., via a carrier) to communicate with base station 105 and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of base station 105), the range of such cells can range from small areas (e.g., buildings, subsets of buildings) to large areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110.

[0067] Macro cells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 115 with a service subscription to a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with the small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a residence or office). 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.

[0068] In some examples, a carrier can support multiple cells, and different cells can be configured based on different protocol types (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)) that can provide access for different types of devices.

[0069] In some examples, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies 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. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0070] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0071] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application, which uses the information or presents it to humans interacting with the application. Some UE 115 devices can be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.

[0072] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception instead of simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115 include: entering a power-saving deep sleep mode when not engaged in active communication, operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a carrier's guard band, or outside a carrier.

[0073] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0074] In some examples, UE 115 can also communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0075] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles may use signals to notify information related to traffic conditions, signal control, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0076] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function Unit (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with 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 connect to network operator IP service 150. Carrier IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0077] Some network devices (e.g., base station 105) may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).

[0078] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is often referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficiently permeable to penetrate structures to provide service to the UE 115 located indoors via a macrocell. Compared to the smaller frequencies and longer waves used in the lower 300 MHz portions of the High Frequency (HF) or Very High Frequency (VHF) spectrum, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0079] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band 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 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding device can be even smaller and more closely spaced compared to UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, EHF transmissions may suffer from even greater atmospheric attenuation and shorter distances compared to SHF or UHF transmissions. The techniques disclosed herein can be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary depending on the country or regulatory authority.

[0080] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations (e.g., LAA) that combine component carriers operating in licensed frequency bands. Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0081] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or 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 base station 105 may be located in different geographical locations. Base station 105 may have antenna arrays with rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Alternatively or additionally, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0082] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used 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).

[0083] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a specific orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0084] As part of beamforming operations, base station 105 or UE 115 may use beam scanning techniques. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Base station 105 may transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by the transmitting device (e.g., base station 105) or by the receiving device (e.g., UE 115)) to identify the beam direction for subsequent transmissions or receptions performed by base station 105.

[0085] Base station 105 can transmit signals (such as data signals associated with a specific receiving device, e.g., UE 115) in a single beam direction (e.g., the direction associated with a particular receiving device, e.g., UE 115). In some examples, the beam direction associated with transmission along a single beam direction can be determined based on signals transmitted in one or more beam directions. For example, UE 115 can receive one or more signals transmitted by base station 105 in different directions and can report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or otherwise acceptable signal quality.

[0086] 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 combined beams for (e.g., from base station 105 to UE 115) transmissions. 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 spanning the system bandwidth or one or more subbands. Base station 105 can transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 can provide feedback on 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 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0087] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the 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 the received signals according to different antenna subarrays, by receiving according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array (any of these operations can be referred to as "listening" according to different reception configurations or reception directions). In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned to a beam direction determined based on listening in different receiver 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 in multiple beam directions).

[0088] The wireless communication system 100 can be a packet-based network operating 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 fragmentation 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 the establishment, configuration, and maintenance of RRC connections between the UE 115 and the base station 105 or core network 130 to support radio bearers for user plane data. At the physical layer, transport channels can be mapped to physical channels.

[0089] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception on 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 under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support HARQ feedback within the same time slot, where the device can provide HARQ feedback for data received in a previous symbol within that time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0090] In some cases, UE 115 can be configured with resource sets for codebook use or non-codebook use (e.g., SRS resource sets), and four SRS resources from the resource set can be configured for UE 115. In some cases, UE 115 can receive DCI from base station 105, and the DCI can indicate a power control identifier (e.g., sri-PUSCH-PowerControlId). UE 115 can use the power control identifier as the code point of the SRI field in the DCI. For example, if the SRI field in the DCI is "X", then the set of uplink power control parameters (path loss reference signal, P0, alpha, closed-loop index, etc.) used for uplink transmissions scheduled by the DCI can correspond to the power control identifier of "X".

[0091] 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 uplink messages for UE 115. The first and / or second control messages may be received from base station 105. The second control message may indicate a resource set identifier and a power control identifier for the transmission of uplink messages. UE 115 may determine the transmit power for uplink messages based on a power control parameter set corresponding to the resource set identifier and the power control identifier. UE 115 may use the resource set associated with the resource set identifier and transmit uplink messages according to the determined transmit power.

[0092] Figure 2 Examples of a wireless communication system 200 supporting path loss reference signal updates for multiple beams are shown according to various aspects of this disclosure. In some examples, the wireless communication system 200 may implement various aspects of the wireless communication system 100. The wireless communication system 200 may include base stations 105-a and 105-b, which may be as referenced Figure 1 An example of a base station 105 is described. Each base station 105 may be associated with multiple cells and multiple coverage areas 110. UE 115-a may communicate with one or more base stations 105 or one or more panels of base station 105.

[0093] UE 115a can be within the coverage area 110-a of base station 105-a and the coverage area 110-b of base station 105-b. UE 115-a can 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.

[0094] UE 115-a can receive a second control message 210 (e.g., a DCI message) from base station 105-a. The second control message 210 may include a resource field 220 indicating one or more SRS resource sets. 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. SRI fields 225 may indicate resource set identifiers and power control identifiers. For example, resource field 220 may indicate a first resource set and a second resource set, and 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 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. SRI field 225-a may indicate or correspond to the first power control identifier, and SRI field 225-b may indicate or correspond to the second power control identifier.

[0095] 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 include resource fields 220 indicating the number of resource sets and a corresponding number of SRI fields 225. Each SRI field 225 may indicate a set of power control parameters associated with a resource set in the number of resource sets indicated by the resource fields 220. The set of power control parameters indicated by the SRI fields 225 can be used to send uplink messages using the resource sets indicated by the resource fields 220.

[0096] UE 115-a may send a set of uplink messages 215 (e.g., one or more PUSCHs) to one or more base stations 105. For example, UE 115-a may send a first uplink message 215 to a first panel of base station 105 and a second uplink message 215 to a second panel of base station 105. In some additional or alternative cases, UE 115-a may send the first uplink message 215 to a first base station 105 and the second uplink message 215 to a second base station 105. For example, uplink message 215-a may be sent to base station 105-a using a first resource set indicated by SRI field 225-a, and uplink message 215-b may be sent to base station 105-b using a second resource set indicated by SRI field 225-b. In some additional or alternative examples, the transmit power of uplink message 215-a may be indicated by SRI field 225-a, and the transmit power of uplink message 215-b may be indicated by SRI field 225-b.

[0097] A resource set can correspond to uplink transmission resources. For example, a resource set can correspond to a set of resource blocks, beams, links, spatial layers, etc. Sending a first uplink message to the base station using a first resource set and sending a second uplink message to the base station using a second resource set can reduce system latency and / or improve data throughput.

[0098] Figure 3A and 3B Examples of uplink transmission techniques 301 and 302 supporting path loss reference signal updates for multiple beams, according to various aspects of this disclosure, are shown. In some examples, uplink transmission techniques 301 and 302 can implement various aspects of wireless communication systems 100 or 200. Operation of uplink transmission techniques 301 and 302 can be implemented by a UE 115 or its components as described herein. The UE can receive a DCI 305 and transmit multiple uplink messages 325 using multiple resource sets 330 and according to an uplink transmission mode 320. The DCI 305 can indicate one or more resource sets 330 and / or power control configurations for one or more uplink messages 325.

[0099] In some cases, DCI 305-a can schedule two or more PUSCH repetitions. The UE can receive DCI 305-a, and DCI 305-a can include resource field 310-a, SRI field 315-a, and SRI field 315-b. In some cases, uplink message 325 associated with resource set 330-a can be directed to a first base station, and uplink message 325 associated with resource set 330-b can be directed to a second base station. Uplink message 325 associated with resource set 330-a can correspond to a first beam, a first precoding, a first spatial domain filter, first spatial relationship information, a first power control parameter set, or a first power control configuration, and uplink message 325 associated with resource set 330-b can correspond to a second beam, a second precoding, a second spatial domain filter, second spatial relationship information, a second power control parameter set, or a second power control configuration.

[0100] Uplink message 325-a can correspond to the first PUSCH transmission timing of uplink transmission mode 320-a, and uplink message 325-b can correspond to the second PUSCH transmission timing of uplink transmission mode 320-a. Uplink message 325-c can correspond to the first PUSCH transmission timing of uplink transmission mode 320-b, uplink message 325-d can correspond to the second PUSCH transmission timing of uplink transmission mode 320-b, uplink message 325-e can correspond to the third PUSCH transmission timing of uplink transmission mode 320-b, and uplink message 325-f can correspond to the fourth PUSCH transmission timing of uplink transmission mode 320-b. Uplink message 325-g can correspond to the first PUSCH transmission timing of uplink transmission mode 320-c, uplink message 325-h can correspond to the second PUSCH transmission timing of uplink transmission mode 320-c, uplink message 325-i can correspond to the third PUSCH transmission timing of uplink transmission mode 320-c, and uplink message 325-j can correspond to the fourth PUSCH transmission timing of uplink transmission mode 320-c.

[0101] The UE can identify uplink transmission mode 320-a based on DCI 305-a, RRC messages, or the UE's configuration. SRI field 315-a can indicate that uplink message 325-a corresponds to resource set 330-a, and SRI field 315-b can indicate that uplink information 325-b corresponds to resource set 330-b. In some cases, the UE can identify uplink transmission mode 320-b based on DCI 305-a, RRC messages, or the UE's configuration. SRI field 315-a can indicate that uplink messages 325-c and 325-d correspond to resource set 330-a, and SRI field 315-b can indicate that uplink messages 325-e and 325-f correspond to resource set 330-b. In some additional or alternative cases, the UE can identify uplink transmission mode 320-c based on DCI 305-a, RRC messages, or the UE's configuration. SRI field 315-a can indicate that uplink messages 325-g and 325-i correspond to resource set 330-a, and SRI field 315-b can indicate that uplink messages 325-h and 325-j correspond to resource set 330-b.

[0102] In some cases, DCI 305-b can utilize different beams to schedule FDM PUSCH. The UE can receive DCI 305-b and use resource sets 330-c and 330-d of uplink transmission mode 320-d to transmit uplink messages 325-k and 325-l. DCI 305-b may include resource field 310-b, SRI field 315-c, and SRI field 315-d. SRI field 315-c may indicate that uplink message 325-k corresponds to resource set 330-c, and SRI field 315-d may indicate that uplink message 325-l corresponds to resource set 320-d. Resource set 330-c may correspond to a first resource block set, and resource set 330-d may correspond to a second resource block set.

[0103] In some cases, DCI 305 can be used to schedule PUSCH transmissions utilizing spatial division multiplexing (SDM) with different beams. For example, resource set 330-c can correspond to a first spatial layer set, and resource set 330-d can correspond to a second spatial layer set. Resource set 330 can correspond to beams, links, resource block sets, carriers, etc. Sending uplink message 325 according to uplink transmission technology 301 or 302 can improve communication reliability. For example, if a 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.

[0104] Figure 4A and 4B Examples of transmission parameter update techniques 401 and 402 supporting path loss reference signal updates for multiple beams, according to various aspects of this disclosure, are shown. In some examples, transmission parameter update techniques 401 and 402 can be implemented in various aspects of wireless communication systems 100 or 200. The operation of transmission parameter update techniques 401 and 402 can be implemented by a UE 115, components of UE 115, base station 105, or components of base station 105 as described herein. The UE can receive downlink messages 405 (e.g., MAC CE) from the base station and transmit multiple uplink messages based on the received downlink messages 405. Downlink messages 405 can be grouped into multiple octets 415, as indicated by bit indicators 410-a and 410-b.

[0105] Downlink message 405-a may include a serving cell ID 430-a indicating the serving cell and a BWP ID 435-a indicating the bandwidth portion (BWP). Downlink message 405-a may include multiple reservation bits 420. For example, downlink message 405-a may include reservation bits 420-a of octet 415-a, reservation bits 420-b of octet 415-b, reservation bits 420-c, reservation bits 420-d, and reservation bits 420-e, and reservation bits 420-f and 420-g of octet 415-c. In some cases, one or more reservation bits 420 may be used to indicate a resource set (e.g., resource-setId, sri-resource-setId, etc.). In some additional or alternative cases, new fields may be added to downlink message 405-a to indicate a resource set.

[0106] In some cases, a combination of an indication of a resource set and an indication of a power control identifier (e.g., SRI ID 440-a, sri-PUSCH-PowerControlId, etc.) can indicate the power control configuration for the resource set. In some cases, downlink message 405-a can update the power control configuration for the resource set by indicating parameters of the resource set (e.g., PUSCH path loss reference RS ID 445-a). The UE can update the power control configuration based on the indicated parameters, the power control identifier, and the resource set. In some cases, the UE will transmit a set of uplink messages (e.g., PUSCH) based on the updated power control configuration. For example, the UE can receive a downlink message (e.g., DCI) indicating an updated power control configuration (e.g., by indicating a resource set and a power control identifier), and the UE can transmit a set of uplink messages scheduled by the downlink message based on the updated power control configuration.

[0107] Downlink message 405-b may include a serving cell ID 430-b and a BWP ID 435-b indicating the serving cell. Downlink message 405-b may include multiple reservation bits 420. For example, downlink message 405-b may include reservation bits 420-h of octet 415-d, reservation bits 420-i, 420-j, 420-k, and 420-l of octet 415-f, reservation bits 420-m of octet 415-g, and reservation bits 420-n and 420-o of octet 415-g. Octet 415-f may include bit 425-a, and bit 425-a may correspond to a reservation bit indicating the presence of a second power control parameter (e.g., a second PUSCH PL RS ID field) in downlink message 405-b. In some examples, bit 425-a, indicating a value of "1", can indicate that additional power control parameters are included in downlink message 405-b, and bit 425-a, indicating a value of "0", can indicate that additional power control parameters are not included in downlink message 405-b. When bit 425-a indicates that additional power control parameters are included in downlink message 405-b, either octet 415-g or a second PUSCH path loss reference RS ID 445-c can be included in downlink message 405-b.

[0108] Downlink message 405-b can support base station updates of path loss reference signal pairs for power control identifiers (e.g., SRI ID 440-b, sri-PUSCH-PowerControlId, etc.). The UE can send multiple uplink messages (e.g., PUSCH) based on the amount of power indicated in downlink message 405-b (e.g., transmit power, PUSCH path loss reference RS ID 445-b, etc.). For example, the UE can receive downlink messages (e.g., DCI) that schedule multiple uplink messages corresponding to the power control configuration associated with SRI ID 440-b. The UE can send multiple uplink messages based on the number of power control parameters included in downlink message 405-b. For example, the UE can send a first uplink message based on PUSCH path loss reference RS ID 445-b and a second uplink message based on PUSCH path loss reference RS ID 445-c. Sending multiple uplink messages based on power control parameters (e.g., transmit power, PUSCH power, PUSCH path loss reference RSID, etc.) indicated in downlink messages (e.g., MAC CE) can reduce system latency and improve reliability.

[0109] Figure 5 An example of a process flow 500 supporting path loss reference signal updates for multiple beams, according to various aspects of this disclosure, is shown. In some examples, process flow 500 may implement various 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 reference... Figure 1 Examples of the corresponding devices described in sections 4 and 4. UE 115-b can transmit uplink messages based on multiple resource sets or beams to improve network efficiency and reduce latency. Alternative examples are possible, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or additional steps may be added.

[0110] At position 505, UE 115b may receive a first control message (e.g., an RRC message) indicating an uplink power control configuration for UE 115b. 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, resource set identifier, or a combination thereof may be associated with a power control configuration (e.g., SRI-PUSCH-PowerControl) for uplink transmission.

[0111] At 510, UE 115-b can receive a second control message (e.g., DCI) scheduled for uplink messages for UE 115-b. The second control message may indicate a resource set identifier and a power control identifier for the uplink messages.

[0112] At point 515, UE 115-b can determine the transmit power for uplink messages based on a set of power control parameters. This set of power control parameters can correspond to a resource set identifier and a power control identifier. In some cases, a combination of the resource set identifier and the power control identifier can correspond to a power control configuration.

[0113] At point 520, UE 115-b can use the resource set associated with the resource set identifier and transmit uplink messages according to the determined transmit power. In some cases, UE 115-b can transmit multiple uplink messages. For example, the second control message can indicate two resource sets, and UE 115-b can use the first resource set to transmit a first uplink message to the first panel of base station 105-d and use the second resource set to transmit a second uplink message to the second panel of base station 105-d. In some additional or alternative examples, UE 115-b can 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 can be the same as the transmit power of the second uplink message, while in other cases, the transmit power of the first uplink message may be different from the transmit power of the second uplink message.
