Transmission parameters for each repetition may be based on parameters determined according to indicated probe reference signal (SRS) resources, such as the number of antenna ports, spatial domain filters or beams, rank or layer number, or any combination thereof. SRS resources may be selected from a set of SRS resources configured at the UE and indicated in control information scheduling uplink communications. Multiple SRS resource sets may be configured at the UE, and one or more indicators in the control information may be mapped to the SRS resources of one or more of these SRS resource sets.

Technical Field

[0003] The following pertains to wireless communication, including multiple repetitive resource signaling techniques used for uplink transmission.

[0004] background

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. 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, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems, which may be referred to as NR systems. These systems can employ various 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 of which simultaneously supports communication from multiple communication devices, which may also be referred to as User Equipment (UE).

[0006] Some wireless communication systems can support communication using one or more antenna arrays at different devices. For example, a network can communicate with a UE using one or more transmit-receive points (TRPs), where each TRP and UE can have one or more antenna arrays to form a directional beam. Efficient communication between each UE and one or more TRPs can help improve network throughput, latency, and reliability, and therefore further improvements to techniques for efficient communication are desirable.

[0007] Overview

[0008] The described techniques relate to improved methods, systems, apparatuses, and devices for supporting multiple repetitions of resource signaling for uplink transmission. Various aspects provide techniques for communication between a User Equipment (UE) and multiple Transmitter Receiving Points (TRPs), wherein the UE can transmit multiple repetitions of uplink communication to one or more TRPs to increase the probability of successfully receiving the uplink communication. In some cases, the UE can transmit uplink communication based on parameters determined according to probe reference signal (SRS) resources (e.g., the number of antenna ports, spatial domain filters or beams, rank or layer number, or any combination thereof). SRS resources can be selected from SRS resource sets configured at the UE, and the SRS resources can be indicated in control information provided to the UE. In some cases, multiple SRS resource sets can be configured at the UE, and one or more indicators in the control information (e.g., downlink control information (DCI)) can be mapped to the SRS resources of one or more of these SRS resource sets.

[0009] In some scenarios, the base station or TRP can transmit configuration information to the UE indicating whether control information transmissions (e.g., DCI) should include one resource indication or two resource indications. Based on this configuration information, the UE can receive control information and determine one or two SRS resource sets based on one or two configured resource indications. One or two SRS resource sets can be associated with different repetitions of uplink communication (such as a first repetition set transmitted to a first TRP and a second repetition set transmitted to a second TRP). In some scenarios, the UE can be configured to receive control information including two resource indications and can identify a specific SRS resource within one or two SRS resource sets based on associated indicators (e.g., a mapping between each indicator and SRS resources in the associated SRS resource set). In other scenarios, the UE can be configured to receive control information including one resource indication and can identify a specific SRS resource within one or two SRS resource sets based on that one resource indication (e.g., a mapping between an indicator and SRS resources in each SRS resource set).

[0063] Detailed description

[0064] In some wireless communication systems, a network may use one or more Transmitter Points (TRPs) to communicate with User Equipment (UE). For example, the network may use a single TRP at a single base station, multiple TRPs at the same base station, or multiple TRPs across multiple base stations to communicate with the UE. In such systems, the transmission parameters for each device (e.g., each UE, each TRP, each base station) may vary across the system (e.g., due to different operating frequencies, different beams, different numbers of antenna ports, etc.), and therefore separate parameters may be indicated for communication with different TRPs. For example, in a multi-TRP system, two or more TRPs may coordinate and configure the UE to transmit multiple repetitive sets of uplink communications, where one repetitive set is directed to a first TRP and a different repetitive set is directed to a second TRP. Such techniques can increase the likelihood that at least one TRP will successfully receive uplink communications, and thus enhance communication reliability. However, when uplink transmissions to different TRPs have different transmission parameters, it may be desirable to provide flexible indications of the different transmission parameters to give the UE sufficient information for communication with different repetitive sets. Existing configuration and control information technologies may, in some situations, fail to provide sufficient information for multiple different recurring sets of uplink communications. Various aspects of this disclosure provide enhanced techniques that allow for flexible and efficient signaling of configuration and control information associated with multiple TRPs.

[0065] In some scenarios, the UE can transmit uplink communication based on parameters determined according to the Signalling Reference (SRS) resources, such as the number of antenna ports, spatial domain filters or beams, rank or layer number, or any combination thereof. The SRS resources can be selected from a set of SRS resources configured at the UE and can be indicated in the control information provided to the UE. In some cases, multiple SRS resource sets can be configured at the UE, and one or more indicators in the control information (e.g., downlink control information (DCI)) can be mapped to the SRS resources of one or more of these SRS resource sets.

[0066] In some deployments, SRS resources can be used to indicate uplink shared channel (e.g., Physical Uplink Shared Channel (PUSCH)) transmission parameters as well as SRS transmission parameters. In some cases, two types of PUSCH transmission are supported: codebook PUSCH transmission and non-codebook PUSCH transmission. In codebook-based transmission, the UE can be configured with an SRS resource set where "Use" is set to "Codebook". Up to four SRS resources within the SRS resource set can be configured for the UE, and in such cases, each SRS resource can be configured (e.g., via Radio Resource Control (RRC) signaling) with several ports (e.g., nrofSRS-Ports(SRS port number)). The SRS Resource Indicator (SRI) field in the DCI that schedules PUSCH transmissions can indicate an SRS resource. In such cases, the number of ports configured for the indicated SRS resource determines the number of antenna ports used for the PUSCH, and the PUSCH is transmitted using the same spatial domain filter (e.g., beam) as the indicated SRS resource. Furthermore, for this type of codebook PUSCH transmission, the number of transport layers (rank) used for the scheduled PUSCH and the transmitted precoder matrix indicator (TPMI) can be determined from separate DCI fields (e.g., the "Precoding Information and Layer Number" field). For example, if two TPMIs are indicated, the same number of transport layers can be applied to both TPMIs. The SRI may include a bit field that is mapped to an index of a configured SRS resource in the SRS resource set, wherein the size of the bit field is based on the number of configured SRS resources in the SRS resource set.

[0067] For non-codebook-based uplink transmissions, the UE may be configured with an SRS resource set where "Use" is set to "Non-codebook". In this case, up to four SRS resources within the SRS resource set can be configured for the UE, and each SRS resource has one port. The SRI field in the uplink DCI (e.g., for scheduling PUSCH) indicates one or more SRS resources, and the number of indicated SRS resources determines the rank (e.g., layer number) used for the scheduled PUSCH. PUSCH communication is transmitted using the same precoder and spatial domain filters (e.g., beamforming) as the indicated SRS resources. The SRI may include a bit field that is mapped to an index of the configured SRS resources in the SRS resource set, where the size of the bit field is based on the number of configured SRS resources in the SRS resource set and the layer number of the PUSCH transmission.

[0068] In situations where multiple repetitions of uplink communication are transmitted to multiple TRPs, configuring multiple SRS resource sets can be useful in some instances, providing additional options for the uplink transmission parameters used for these multiple repetitions. For example, if the first link between the UE and the first TRP is blocked, the first repetition of the uplink transmission to the first TRP may not be successfully received. However, if the second link between the UE and the second TRP is not blocked, the second repetition of the uplink transmission to the second TRP can be successfully received and decoded. Thus, such techniques can increase communication diversity and thereby enhance reliability and efficiency in situations where one or more links may experience relatively poor channel conditions. In some cases, different PUSCH transmission times (i.e., repetitions) corresponding to the same Transport Block (TB) are transmitted in different time slots or mini-time slots, and the number of repetitions can be configured (e.g., via RRC signaling) or can be dynamically indicated (e.g., in the DCI scheduling uplink communication, such as in the Time Domain Resource Allocation (TDRA) field).

[0069] In existing deployments, all repetitions use the same beam for transmission (e.g., the SRI field of the DCI is applied to all repetitions), and this same beam used for all repetitions may not be suitable for reception at each of the different TRPs, panels, antennas, or any combination thereof when different PUSCH repetitions are intended to be received at different TRPs, panels, antennas, or any combination thereof on the base station side. To provide the use of different beams for transmitting different repetitions, in some cases, multiple SRS resource sets can be configured such that different repetitions can use uplink transmission parameters associated with different SRS resources in different SRS resource sets. Furthermore, in some cases, SRS resources within one SRS resource set may be sufficient to indicate appropriate uplink transmission parameters, and various aspects of this disclosure provide the flexibility to indicate one or more SRIs and to map SRIs to SRS resources from one or more SRS resource sets. Such techniques can be used for codebook-based or codebook-free uplink communication.

[0070] According to the techniques discussed herein, a base station or TRP can configure multiple SRS resource sets and transmit configuration information to the UE indicating whether control information transmissions (e.g., DCI) should include one or two resource indicators. Based on this configuration information, the UE can receive control information and determine one or two SRS resource sets based on the configured resource indicators. One or two SRS resource sets can be associated with different repetitions of uplink communication (such as a first repetition set transmitted to a first TRP and a second repetition set transmitted to a second TRP). In some cases, the UE can be configured to receive control information including two resource indicators and can identify a specific SRS resource within one or two SRS resource sets based on associated indicators (e.g., based on a mapping between each indicator and SRS resources in the associated SRS resource set). In other cases, the UE can be configured to receive control information including one resource indicator and can identify a specific SRS resource within one or two SRS resource sets based on that one resource indicator (e.g., based on a mapping between an indicator and SRS resources in each SRS resource set).

[0071] The aspects of this disclosure are initially described in the context of wireless communication systems. The aspects of this disclosure are further illustrated and described by way of process flow diagrams, apparatus diagrams, system diagrams, and flowcharts relating to multiple repeated SRS resources and multiple repeated resource signaling techniques for uplink transmission.

[0072] Figure 1 Examples of a wireless communication system 100 supporting multiple repetitive resource signaling techniques for uplink transmission according to various aspects of this disclosure are described. 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 Advanced 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, communication with low-cost and low-complexity devices, or any combination thereof.

[0073] Base station 105 can be distributed across a geographical area to form wireless communication system 100, and can be different types of devices or devices with different capabilities. Base station 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 on the coverage area 110. Coverage area 110 can be an example of a geographical area over which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0074] Each UE 115 can be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. Each UE 115 can be a different type of device or a device with different capabilities. Figure 1 The document describes some example UE 115s. The UE 115 described herein can communicate with various types of devices, such as other UE 115s, base station 105, or network equipment (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment). Figure 1 As shown in the image.

[0075] Each base station 105 may communicate with the core network 130, or with each other, or both. For example, base station 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base stations 105 may communicate with each other directly (e.g., directly between base stations 105), indirectly (e.g., via the core network 130), or directly and indirectly on backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links.

[0076] 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 transceiver station, radio base station, access point, radio transceiver, B node, evolved B node (eNB), next-generation B node or gigabit B node (any of which may be referred to as gNB), home B node, home evolved B node, or other suitable terms.

[0077] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any 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, which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0078] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, as well as base station 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 As shown in the image.

[0079] 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 the radio spectrum band (e.g., a bandwidth portion (BWP)) operating 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 coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0080] In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate the operation of 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 located according to a channel grid for discovery by UE 115. The carrier may operate in an autonomous mode in which initial acquisition and connection can be performed by UE 115 via that carrier, or in a non-autonomous mode in which the carrier may connect to carriers anchored using different carriers (e.g., different carriers of the same or different radio access technologies).

[0081] 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).

[0082] 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 carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of several defined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz) of a carrier for a particular radio access technology. Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication over a specific carrier bandwidth, or may be configurable to support communication over a single carrier bandwidth within 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 over a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0083] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may 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 may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate the UE 115 can achieve. 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 using multiple spatial layers can further improve the data rate or data integrity of communication with the UE 115.

[0084] One or more sets of parameters can be supported for a carrier, where the parameter set may include the subcarrier spacing (Δf) and the cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter designs. In some examples, the 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 the UE 115 can be limited to one or more active BWPs.

[0085] The time interval of base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period T. s =1 / (Δf) max ·N f )T s =1 / (Δf) max ·N f ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, while N f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with 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).

[0086] 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 (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into several 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 several 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 mini-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier interval or the operating frequency band.

[0087] A subframe, time slot, mini-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. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0088] Physical channels can be multiplexed on a carrier using various techniques. Physical control channels and physical data channels can be multiplexed on a downlink carrier, for example, using one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques. 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., CORESET) can be configured for a set of UEs 115. For example, one or more UEs 115 can monitor or search 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 in one or more aggregation levels arranged in a cascaded manner. An 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 in 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 configured to send control information to a specific UE 115.

[0089] Each base station 105 may provide communication coverage via one or more cells (e.g., macrocells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with base station 105 (e.g., on a carrier) and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or others). 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. The extent of such cells may vary from smaller areas (e.g., structures, subsets of structures) to larger areas depending on various factors (such as the capabilities of base station 105). For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, among other examples.

[0090] Macrocells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs 115 that have service subscriptions with a network provider supporting the macrocell. Small cells may be associated with a lower-power base station 105 (compared to macrocells) and may operate in the same or different (e.g., licensed or unlicensed) frequency bands as macrocells. Small cells may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a Closed Subscriber Group (CSG), or UEs 115 associated with a user in a home or office). Base station 105 may support one or more cells and may also support communication on one or more cells using one or more component carriers.

[0091] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0092] In some examples, base station 105 may be mobile, and thus provide communication coverage to mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the 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 to various geographic coverage areas 110.

[0093] 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 may 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 that uses the information or presents it to people interacting with the application. Some UE 115 devices may 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, wilderness survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial toll collection.

[0094] Wireless communication system 100 may be configured to support ultra-reliable communication or low latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low latency communication (URLLC) or mission-critical communication. UE 115 may be designed to support ultra-reliable, low latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private or group communication and may be supported by one or more mission-critical services, such as Mission-Critical Talk-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 business applications. The terms ultra-reliable, low latency, mission-critical, and ultra-reliable low latency are used interchangeably herein.

[0095] In some examples, UE 115 may also be able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UE 115s utilizing D2D communication may 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 may be unable to receive transmissions from base station 105 for other reasons. In some examples, groups of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every 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 the individual UE 115s without involving base station 105.

[0096] 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-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information related to traffic conditions, signaling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate via vehicle-to-network (V2N) communication through one or more network nodes (e.g., base station 105) with roadside infrastructure (such as roadside units), or with the network, or with both.

[0097] Core network 130 provides 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). The EPC or 5GC may 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 (UPF)) routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which provides IP address allocation and other functions. The user plane entity may be connected to one or more network operator IP services 150. The IP service 150 may include access to the Internet, intranet, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0098] Some network devices (such as 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 each 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 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 various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).

[0099] Wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 MHz to 300 GHz. Generally, the 300 MHz to 3 GHz band is referred to as a UHF band or decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can penetrate various structures sufficiently for macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the lower HF or VHF portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0100] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) zoning using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band) or in the extremely high frequency (EHF) zoning using a spectrum (e.g., from 30 GHz to 300 GHz) (also known 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 devices can be smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein can be employed across transmissions using one or more different frequency zonings, and the frequency band usage specified across these frequency zonings may vary by country or regulatory authority.

[0101] Wireless communication system 100 may utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 may 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 spectrum bands, devices (such as base station 105 and UE 115) may employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands may be based on carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in licensed frequency bands. Operation in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0102] Base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can 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 an antenna array with several 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. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0103] Base station 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique is known 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 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.

[0104] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be 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 particular orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element may be defined by a beamforming weight set associated with a particular orientation (e.g., the antenna array relative to the transmitting or receiving device, or relative to some other orientation).

[0105] Base station 105 or UE 115 may use beamsweeping techniques as part of beamforming operations. 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. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by the transmitting device (such as base station 105) or the receiving device (such as UE 115)) to identify the beam direction that base station 105 will use for later transmission or reception.

[0106] Some signals (such as data signals associated with a specific receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the receiving device (such as UE 115)). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signals received by UE 115 with the highest signal quality or other acceptable signal quality.

[0107] In some examples, transmissions performed by a device (e.g., by base station 105 or UE 115) may be executed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate combined beams for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and this feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals that may be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 may provide feedback for beam selection, which may 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 use similar techniques to transmit signals multiple times in different directions (e.g., to identify the beam direction used by UE 115 for subsequent transmission or reception) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0108] A receiver device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiver device may attempt multiple receive directions by: receiving via different antenna subarrays; processing received signals according to different antenna subarrays; receiving according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets); or processing received signals according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of the antenna array, any of which may be referred to as "listening" according to different receive configurations or receive directions. In some examples, the receiver device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0109] Additionally or alternatively, base station 105 in wireless communication system 100 may include one or more TRPs. Each TRP may be associated with one or more antenna ports, beams, and beam indices. In some cases, UE 115 may transmit one or more uplink communications to multiple TRPs, and such communications may include multiple repetitions of uplink communications to multiple TRPs to enhance the probability of successfully receiving the uplink communications. In some cases, UE 115 may transmit uplink communications based on parameters determined from SRS resources, such as the number of antenna ports, spatial domain filters or beams, rank or layer number, or any combination thereof. SRS resources may be selected from an SRS resource set configured at UE 115, and the SRS resources may be indicated in control information provided to UE 115. In some cases, multiple SRS resource sets may be configured at UE 115, and one or more indicators in the control information may be mapped to the SRS resources of one or more SRS resource sets in these SRS resource sets.

[0110] Figure 2 Examples of wireless communication systems 200 supporting multiple repetitive resource signaling techniques for uplink transmission according to various aspects of this disclosure are explained. For example, the wireless communication system 200 may include a first base station 105-a, a second base station 105-b, and a UE 115-a, which may be referenced... Figure 1Examples of the corresponding devices described herein. It should be understood that references to specific wireless devices (e.g., UE, TRP, base station) in the following figures are provided for illustrative purposes, and different wireless devices not specifically mentioned herein may be used interchangeably with those described herein. Similarly, in some cases, the operations described by UE 115 may be performed by base station 105 (or TRP), and vice versa. In some examples, multiple TRPs may each be an independent TRP or may be part of one base station 105 or different base stations 105. Additionally or alternatively, base station 105 or TRP may be a component or example of an IAB node, a repeater node (e.g., configured with some retransmission capability), etc. Furthermore, UE 115-a may be an example of a client equipment (CPE), a sidelink node, a repeater node, etc.

[0111] (For example,) a first base station 105-a (associated with a first TRP) can provide coverage area 110a, and (for example,) a second base station 105-b (associated with a second TRP) can provide coverage area 110b. Additionally or alternatively, each base station 105 can communicate with UE 115-a on one or more communication links. For example, the first base station 105-a can transmit downlink communication to UE 115-a via link 205, and UE 115-a can transmit uplink communication to the first base station 105-a via link 210. In this example, UE 115-a can also transmit uplink communication to the second base station 105-b via link 215. In some examples, base station 105 and UE 115-a can communicate using specific directional beams identified by one or more beam training protocols.

[0112] In some scenarios, to allow uplink communication, both base station 105 and UE 115-a may be configured with two SRS resource sets. Multiple SRS resource sets can be provided for codebook-based or non-codebook-based communication, and SRS resources from one or both of these SRS resource sets can be indicated by one or both resource indication (e.g., SRI) fields transmitted to UE 115-a in control information 225. In some scenarios, UE 115-a may receive configuration information 220 indicating the presence of a first resource indication, or both a first resource indication and a second resource indication, in control information 225. For example, configuration information 220 may be configuration information notified via RRC signaling. One or more resource indication fields can provide indications of SRS resources within one or two SRS resource sets that provide uplink transmission parameters for a first duplicate set 230 and a second duplicate set 235 for uplink communication. In this example, the first repeat set 230 is transmitted to the first base station 105-a (e.g., transmitted to the first TRP at the first base station 105-a) and the second repeat set 235 is transmitted to the second base station 105-b (e.g., transmitted to the second TRP at the second base station 105-b).

[0113] As indicated, UE 115-a can be configured by configuration information 220 to anticipate one resource indication or two resource indications (e.g., in one SRI field or in two SRI fields). In the case where two resource indications are configured, UE 115-a can receive control information 225 and determine that the scheduling information for uplink communication indicates one SRS resource set (e.g., only the first SRS resource set). In this case, the resource indication can indicate one or more SRS resources within the first SRS resource set, and the second resource indication field can be ignored. In this case, the uplink transmission parameters for the first repeat set 230 and the second repeat set 235 are determined based on the first SRS resource set.

[0114] In other scenarios, control information 225 may indicate two SRS resource sets, and a first resource indication field may indicate one or more SRS resources within the first SRS resource set, while a second resource indication field may indicate one or more SRS resources within the second SRS resource set. In such cases, the uplink transmission parameters for the first repeat set 230 are determined based on the first resource indication for the SRS resources within the first SRS resource set, and the uplink transmission parameters for the second repeat set 235 are determined based on the second resource indication for the SRS resources within the second SRS resource set.

[0115] As indicated, in some cases, UE 115-a may be configured by configuration information 220 to expect a single resource indication field in control information 225 (e.g., a first SRI field is configured, and a second SRI field is not configured). In such cases, control information 225 (e.g., scheduling uplink DCIs that repeat PUSCH) may indicate one SRS resource set (e.g., indicating only the first SRS resource set), and the resource indication field may indicate only one or more SRS resources within the first SRS resource set. In other cases, control information 225 may indicate two SRS resource sets, and the two resource indication fields may indicate SRS resources from the first SRS resource set and the second SRS resource set, respectively.

[0116] In some cases, the configuration of one or two Resource Indicator (SRI) fields can be configured separately for different Control Information 225 formats (e.g., via RRC signaling). That is, two SRI fields corresponding to two SRS resource sets can be included in different DCI formats. In some examples, the number of SRI fields may depend on the configuration of the number of configured SRS resource sets at UE 115-a, rather than the explicitly configured number of SRI fields. If UE 115-a is configured with two SRS resource sets and one or both of these SRS resource sets have more than one SRS resource, then the DCI may include two SRI fields. Therefore, the rules for the number of SRI fields in the DCI may depend on the number of configured SRS resource sets and the number of configured SRS resources in each SRS resource set. Therefore, if the number of SRS resource configurations (e.g., the number of SRS resource sets and the number of SRS resources per SRS resource set) is configured via SRS configuration information (e.g., via RRC signaling), the number of SRI fields in the DCI can depend on / be configured according to the SRS configuration. For example, a first control information format corresponding to DCI format 0_1 ​​can be configured for one or two resource indication fields, and a second control information format corresponding to DCI format 0_2 can be configured independently and separately for one or two resource indication fields. In some examples, each SRI field can indicate the SRI per TRP. Resource indication signaling can be used for codebook-based uplink communication (where one SRS resource within an SRS resource set is indicated) and for non-codebook-based uplink communication (where one or more SRS resources within an SRS resource set can be indicated). In some examples, for non-codebook-based uplink communication, resource indication signaling can support the same number of layers applied repeatedly. Using this technique, the presence of one or two resource indication fields can be configured semi-statically (e.g., via RRC signaling), while one or more SRS resource sets for a specific uplink communication can be dynamically indicated in control information 225. Additionally or alternatively, the described technique can support dynamic switching between multi-TRP operations and single-TRP operations.

[0117] This type of technology allows for the configuration of multiple SRS resource sets at UE 115-a, while enabling flexible scheduling of uplink communications with repetitions that can utilize transmission parameters based on SRS resources from one or both of the configured SRS resource sets. Therefore, base station 105 can select one or more SRS resource sets for repetitions of a specific PUSCH transmission based on beams suitable for different repetitions (e.g., where the identified beam is associated with a TRP associated with a different SRS resource set). This selection and identification of SRS resource sets and SRS resources allows base station 105 to schedule uplink communications with repetitions based on channel conditions and can increase the likelihood of successfully decoding uplink communications, thereby enhancing the efficiency and reliability of wireless communication. Various examples and aspects are referenced. Figures 3 to 6 To describe in more detail.

[0118] Figure 3 Examples of control and shared channel communication 300 supporting multiple repetitive resource signaling techniques for uplink transmission according to various aspects of this disclosure are explained. For example, control and shared channel communication 300 can be implemented in, as per reference... Figure 1 and Figure 2 The wireless communication system described herein uses UE 115 and base station 105. It should be understood that references to specific wireless devices (e.g., UE, TRP, base station) in the exemplary figures are provided for illustrative purposes, and different wireless devices not specifically mentioned herein may be used interchangeably with those described herein. Similarly, in some cases, the operations described by UE 115 may be performed by base station 105, and vice versa. In some examples, the base station may be an example of one or more TRPs, or may include one or more TRPs. Additionally or alternatively, the base station may each be an example of an IAB node, a repeater node (e.g., configured with some retransmission capability), etc. Furthermore, the UE may be an example of a CPE, a sidelink node, a repeater node, etc.

[0119] In this example, the scheduling DCI 305 can schedule uplink transmissions with a first repeat set 310 and a second repeat set 315. Furthermore, the first repeat set 310 may include a first repeat 310-a and a second repeat 310-b, both of which are transmitted to a first TRP. Similarly, the second repeat set 315 may include a third repeat 315-a and a fourth repeat 315-b, both of which are transmitted to a second TRP. Each repeat in both the first repeat set 310 and the second repeat set 315 may include the same TB, and therefore multiple repeats at multiple different TRPs can increase the probability of successfully decoding the TB at either or both of the first TRP and the second TRP. As discussed herein, the scheduling DCI 305 may include a single resource indication field (as will be referenced). Figure 5 (Discussed in more detail), or multiple resource indicator fields (as will be referenced) Figure 4 (To be discussed in more detail).

[0120] Figure 4 Examples of control information 400 with multiple resource indicators supporting multiple repetitive resource signaling techniques for uplink transmission according to various aspects of this disclosure are explained. For example, control information 400 can be used in a wireless communication system including UE 115 and base station 105 as described herein.

[0121] In this example, uplink DCI 405 may include scheduling information for uplink PUSCH communication from the UE to one or more TRPs. In this example, the UE may be configured (e.g., via RRC signaling) with two SRS resource sets, including a first SRS resource set 420 and a second SRS resource set 430. Furthermore, the UE may be configured to have control information with two SRI fields (including a first SRI field 410 and a second SRI field 415). In this example, the first SRS resource set 420 may be configured with four SRS resources, including a first SRS resource 425-a, a second SRS resource 425-b, a third SRS resource 425-c, and a fourth SRS resource 425-d. Similarly, the second SRS resource set 430 may be configured with four SRS resources, including a first SRS resource 435-a, a second SRS resource 435-b, a third SRS resource 435-c, and a fourth SRS resource 435-d. In this example, the first SRI field 410 indicates the first SRS resource 425-a and the third SRS resource 425-c within the first SRS resource set 420. The second SRI field 415 in this example indicates the second SRS resource 435-b and the third SRS resource 435-c within the second SRS resource set 430. Therefore, in this example, uplink communication can be transmitted in a first set using uplink transmission parameters based on the first SRI field 410 (e.g., suitable for transmission to the first TRP using the first beam), and in a second set using uplink transmission parameters based on the second SRI field 415 (e.g., suitable for transmission to the second TRP using the second beam).

[0122] In some cases, for codebook-based PUSCH, the UE can expect that the SRS resources indicated in the first SRS resource set 420 (e.g., via the first SRI field 410) have the same number of ports as the SRS resources indicated in the second SRS resource set 430 (e.g., via the second SRI field 415). In other cases, for non-codebook-based PUSCH, the UE can expect that the number of SRS resources indicated in the first SRS resource set 420 (e.g., via the first SRI field 410) is the same as the number of SRS resources indicated in the second SRS resource set 430 (e.g., via the second SRI field 415). This provides that the two PUSCH repetition sets have the same rank, which is determined by the number of indicated SRS resources in the SRS resource sets. In some examples, for non-codebook-based PUSCHs (e.g., multi-TRP PUSCHs), the first SRI field 410 can be used to determine entries for the second SRI field 415, which may include at least one SRI combination corresponding to the indicated rank (e.g., number of levels) of the first SRI field 410. For example, the number of bits N2 for the second SRI field 415 can be determined by the maximum number of code points for each rank associated with the first SRI field 410. For each rank x, the first K... x Each code point can be mapped to a K-order rank x associated with the first SRI field 410. x One SRI, and the rest (2 N2 -K x ( ) code points can be preserved.

[0123] For reference Figure 2In some cases, the uplink DCI 405 may indicate one SRS resource set or two SRS resource sets. As discussed, when the uplink DCI 405 indicates one SRS resource set, the UE may ignore any indication provided in the second SRI field 415. In some cases, the indication of one SRS resource set versus two SRS resource sets in the uplink DCI 405 may be provided by a bit field within the uplink DCI 405. For example, the bit field may include two bits indicating one of the following three possibilities: (1) only the first SRS resource set 420 (e.g., all repetitions correspond to and target the first TRP associated with the first SRS resource set 420); (2) only the second SRS resource set 430 (e.g., all repetitions correspond to and target the second TRP associated with the second SRS resource set 430); or (3) both the first SRS resource set 420 and the second SRS resource set 430 are to be used (e.g., the two repetition sets correspond to and target the first and second TRPs respectively), and which SRS resource set the UE wants to use corresponds to which SRI field.

[0124] In other examples, the bit field within the uplink DCI 405 indicating one SRS resource set versus two SRS resource sets could be a 1-bit field indicating either one or two SRS resource sets. In such cases, when this bit field indicates one SRS resource set, whether to use the first SRS resource set 420 or the second SRS resource set 430 can be based on assumptions about the use of the first SRS resource set 420 (or the second SRS resource set 430), or can be indicated to the UE along with configuration information (e.g., in RRC signaling). In a further case, a different bit field in the uplink DCI 405 can be used to determine whether the first SRS resource set 420 or the second SRS resource set 430 should be assumed. For example, if there are two SRI fields in the uplink DCI 405 and one of the SRI fields is not used (e.g., because it indicates a single SRS resource set), then the second SRI field 415 (e.g., the first bit or the last bit of the SRI field) can be used to indicate whether it indicates the first SRS resource set 420 or the second SRS resource set 430.

[0125] In other cases, a separate bit field indicating which SRS resource set to use when an SRS resource set is indicated for uplink communication may not be provided, and reserved values ​​of SRI code points (e.g., all 0s or all 1s) may be used to indicate that no SRS resource set is indicated (e.g., if the first SRI field 410 is set to all "0", no SRS resource from the first SRS resource set 420 is indicated; if the second SRI field 415 is set to all "0", no SRS resource from the second SRS resource set 430 is indicated), and if the SRI field is not set to the reserved value, the value of the SRI field indicates one or more SRS resources within the corresponding SRS resource set (in such cases, the UE would not expect both SRI fields to be set to reserved values).

[0126] Figure 5 Examples of control information 500 with a single resource indicator supporting multiple repetitive resource signaling techniques for uplink transmission according to various aspects of this disclosure are explained. For example, control information 500 can be used in a wireless communication system including UE 115 and base station 105 as described herein.

[0127] In this example, the uplink DCI 505 may include scheduling information for uplink PUSCH communication from the UE to one or more TRPs. In this example, the UE may be configured (e.g., via RRC signaling) with two SRS resource sets, including a first SRS resource set 520 and a second SRS resource set 530. Furthermore, the UE may be configured to have control information with a single SRI field 510. In this example, the first SRS resource set 520 may be configured with four SRS resources, including a first SRS resource 525-a, a second SRS resource 525-b, a third SRS resource 525-c, and a fourth SRS resource 525-d. Similarly, the second SRS resource set 530 may be configured with four SRS resources, including a first SRS resource 535-a, a second SRS resource 535-b, a third SRS resource 535-c, and a fourth SRS resource 535-d. In this example, a single SRI field 510 indicates the same related SRS resources within both the first SRS resource set 520 and the second SRS resource set 530 (e.g., first SRS resource 525-a and third SRS resource 525-c of the first SRS resource set 520, and first SRS resource 535-a and third SRS resource 535-c of the second SRS resource set 530). Therefore, in this example, uplink communication can be transmitted in a first repeating set using uplink transmission parameters based on the first SRS resource set 520 and in a second repeating set using uplink transmission parameters based on the second SRS resource set 530.

[0128] For codebook-based PUSCH, based on the single SRI field 510 configured in this case, the UE can expect the i-th configured SRS resource in the first SRS resource set 520 to have the same number of ports as the i-th SRS resource in the second SRS resource set 530. This configuration provides two repeating sets of PUSCH with the same number of antenna ports (which is determined by the number of ports of the associated SRS resources).

[0129] In some examples, for both codebook-based and non-codebook-based PUSCH, one of the following conditions applies. The first condition specifies that the first SRS resource set 520 and the second SRS resource set 530 have the same number of SRS resources (e.g., ensured by configuration constraints on these two SRS resource sets). The second condition specifies that the number of bits in a single SRI field 510 of the uplink DCI 505 is determined based on the maximum of the number of SRS resources in the first SRS resource set 520 and the second SRS resource set 530. Such conditions specify that a single SRI field 510 indicates SRS resources(s) within both the first SRS resource set 520 and the second SRS resource set 530, whereas in cases where two separate SRI fields exist, such conditions may be unnecessary, as referenced... Figure 4 The subject of discussion.

[0130] Figure 6 Examples of process flow 600 supporting multiple repetitive resource signaling techniques for uplink transmission according to various aspects of this disclosure are described. In some examples, process flow 600 may implement aspects of wireless communication system 100 or 200. For example, process flow 600 includes UE 115-b, first base station 105-c, and second base station 105-d, each of which may be a reference Figures 1 to 5 Examples of corresponding devices described. Process flow 600 can illustrate examples of how the first base station 105-c, the second base station 105-d, and the UE 115-b determine multiple repeating uplink transmission parameters for uplink communication to different TRPs.

[0131] In the following description of process flow 600, operations between UE 115-b, the first base station 105-c, and the second base station 105-d may be transmitted in a different order than that shown, or operations performed by UE 115-b, the first base station 105-c, and the second base station 105-d may be performed in a different order or at different times. Some operations may also be excluded from process flow 600, or other operations may be added to process flow 600. It should be understood that although UE 115-b, the first base station 105-c, and the second base station 105-d are shown as performing several operations of process flow 600, any wireless device (e.g., UE, client device, base station, TRP, Integrated Access and Backhaul (IAB) node, repeater with different types of capabilities in terms of signal repetition (also referred to as "smart" or "dumb" repeater, or some other term), or sidelink node, etc.) may also perform the operations shown.

[0132] Optionally, at 605, UE 115-b may transmit a measurement report to the first base station 105-c (e.g., which may include a first TRP). This measurement report may provide information on one or more beams suitable for communication with UE 115-b associated with one or more TRPs. In some cases, the measurement report may indicate that UE 115-b is experiencing relatively poor channel conditions associated with one or more TRPs, which may indicate that multiple repetitions of uplink communication may be required to achieve a communication reliability objective.

[0133] At 610, the first base station 105-c can determine configuration information for UE 115-b. In some cases, the first base station 105-c can be a serving base station and can determine multiple repetitions of uplink communication to be transmitted by UE 115-b. In some cases, the configuration information may include the configuration of multiple SRS resource sets, each SRS resource set may be associated with a different TRP (e.g., a first SRS resource set may provide SRS resources suitable for communication with one or more TRPs, and a second SRS resource set may provide SRS resources suitable for communication with one or more TRPs (which may include some TRPs of the same TRP as the first SRS resource set or exclude TRPs of the same TRP as the first SRS resource set). The configuration information may also include control information regarding scheduling uplink communication, indicating whether to include one resource indicator or two resource indicators (e.g., scheduling DCI to include one SRI field or multiple SRI fields). Additionally or alternatively, the configuration information may also configure one of the SRS resource sets to be associated with a specific SRI field in the control information. In some cases, the first base station 105-c may optionally exchange TRP coordination information with the second base station 105-d, as indicated at 615. For example, such coordination information may include information about uplink resources for anticipated uplink communication.

[0134] At 620, the first base station 105-c may transmit SRS resource configuration to the UE 115-b. In some cases, the SRS resource configuration may be transmitted as part of the RRC signaling between the UE 115-b and the first base station 105-c. At 625, the first base station 105-c may determine the repetition level, SRS resources, and uplink allocation for uplink communication from the UE 115-b.

[0135] At 630, the first base station 105-c, the second base station 105-d, or both may transmit DCI to UE 115-b. DCI may include indications of SRS resource sets to be used for uplink communication, the number of repetitions of uplink communication, indications of one or more SRS resources associated with uplink communication within one or more SRS resource sets, or any combination thereof.

[0136] In 635, UE 115-b can determine repeated uplink transmission parameters for uplink communication. In some cases, UE 115-b can determine which SRS resource in the configured SRS resource set should be associated with uplink communication, such as by using one or more techniques as discussed herein.

[0137] Optionally, at 640, UE 115-b may transmit one or more SRSs to the first base station 105-c, the second base station 105-d, or both. As discussed herein, the one or more SRSs may have uplink transmission parameters determined based on the indicated SRS resources. At 645, UE 115-b may transmit a first PUSCH repetition set to the first base station 105-c (and optionally to the second base station 105-d), and at 650, UE 115-b may transmit a second PUSCH repetition set to the second base station 105-d (and optionally to the first base station 105-c). Repetitions in different repetition sets may have uplink transmission parameters determined based on the indicated SRS resources, such as by using various different techniques as provided herein.

[0138] Figure 7 A block diagram 700 of a device 705 supporting multiple repetitive resource signaling techniques for uplink transmissions according to various aspects of this disclosure is shown. Device 705 may be an example of various aspects of UE 115 as described herein. Device 705 may include a receiver 710, a transmitter 715, and a communication manager 720. Device 705 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0139] Receiver 710 may provide means for receiving information, such as packets, user data, control information, or any combination thereof, associated with various information channels (e.g., control channels, data channels, information channels related to multiple repeating resource signaling techniques for uplink transmission). The information may be transmitted to other components of device 705. Receiver 710 may utilize a single antenna or a collection of multiple antennas.

[0140] Transmitter 715 may provide means for transmitting signals generated by other components of device 705. For example, transmitter 715 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to multiple repeating resource signaling techniques for uplink transmission). In some examples, transmitter 715 may be co-located with receiver 710 in a transceiver module. Transmitter 715 may utilize a single antenna or a collection of multiple antennas.

[0141] The communication manager 720, receiver 710, transmitter 715, or various combinations thereof, or various components thereof, may be examples of apparatuses for performing various aspects of multiple repetitive resource signaling techniques for uplink transmission as described herein. For example, the communication manager 720, receiver 710, transmitter 715, or various combinations thereof, or components thereof, may support methods for performing one or more functions described herein.

[0142] In some examples, the communication manager 720, receiver 710, transmitter 715, or various combinations or components thereof may be implemented in hardware (e.g., in a communication management circuitry system). This hardware may include a processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, configured to serve as or otherwise support means for performing the functions described herein. In some examples, the processor and memory coupled to the processor may be configured to perform one or more functions described herein (e.g., by executing instructions stored in memory by the processor).

[0143] Additionally or alternatively, in some examples, the communication manager 720, receiver 710, transmitter 715, or various combinations or components thereof may be implemented by code executed by a processor (e.g., as communication management software or firmware). If implemented by code executed by a processor, the functionality of the communication manager 720, receiver 710, transmitter 715, or various combinations or components thereof may be performed by a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or any combination of these or other programmable logic devices (e.g., means configured or otherwise supported for performing the functions described in this disclosure).

[0144] In some examples, the communication manager 720 may be configured to use or otherwise cooperate with the receiver 710, transmitter 715, or both to perform various operations (e.g., receiving, monitoring, transmitting).

In some examples, the first bit value provides a predetermined indication that a first uplink communication will use a first SRS resource set. In some examples, the first bit value is configured by the SRS configuration information to indicate that the first uplink communication will use a first SRS resource set. In some examples, the first bit value indicates that a different information field in the first control information provides an indication that the first uplink communication will use either a first SRS resource set or a second SRS resource set. In some examples, an indication that one of the first or second SRS resource sets is not used is provided by a reserved value for the resource indication of the associated SRS resource set.

Such techniques can allow for enhanced reliability of wireless communication and thus provide more efficient utilization of communication resources, reduced power consumption (through reduced retransmissions), reduced latency (through reduced retransmissions), and more efficient utilization of communication resources. Furthermore, such techniques provide the flexibility to schedule uplink communications with repetitions based on one or more SRS resource sets, which can enhance network efficiency by efficiently scheduling uplink communications according to available network and radio resources.

[0186] Figure 13 A block diagram 1300 is shown of a communication manager 1320 supporting multiple repetitive resource signaling techniques for uplink transmission according to various aspects of this disclosure. The communication manager 1320 may be an example of the communication manager 1120, communication manager 1220, or aspects of both described herein. The communication manager 1320 or its various components may be examples of means for performing various aspects of multiple repetitive resource signaling techniques for uplink transmission as described herein. For example, the communication manager 1320 may include an SRS configuration manager 1325, a control information manager 1330, an uplink transmission parameter manager 1335, an uplink communication manager 1340, an SRI manager 1345, a DCI format manager 1350, or any combination thereof. Each of these components may communicate directly or indirectly with each other (e.g., via one or more buses).

SRS configuration manager 1325 may be configured or otherwise support means for transmitting SRS configuration information to the UE, the SRS configuration information indicating whether control information for providing uplink permission to the UE includes one resource indicator for SRS resources or two resource indicators for SRS resources. Control information manager 1330 may be configured or otherwise support means for transmitting first control information to the UE, the first control information scheduling two or more repetitions of a first uplink communication and indicating the association between the two or more repetitions of the first uplink communication and a first SRS resource set, a second SRS resource set, or both.

Uplink communication manager 1340 may be configured or otherwise supported to receive a first set of repeats of the first uplink communication using the first set of uplink transmission parameters and to receive a second set of repeats of the first uplink communication using the second set of uplink transmission parameters.

[0188] In some examples, a first SRS resource set is associated with a first duplicate set of a first uplink communication and a second SRS resource set is associated with a second duplicate set of the first uplink communication, wherein the first duplicate set of the first uplink communication is transmitted to a first TPR and the second duplicate set of the first uplink communication is transmitted to a second TPR.

[0189] In some examples, the first repeat set of the first uplink communication and the second repeat set of the first uplink communication are either codebook-based physical uplink shared channel transmissions or codebook-free physical uplink shared channel transmissions. In some examples, to support the transmission of first control information, the control information manager 1330 may be configured or otherwise supported to support means for transmitting a first resource indicator in the first control information, the first resource indicator providing a first SRS resource in a first SRS resource set. In some examples, to support the transmission of first control information, the control information manager 1330 may be configured or otherwise supported to support means for transmitting a second resource indicator in the first control information, the second resource indicator providing a second SRS resource in a second SRS resource set.

[0190] In some examples, the SRS configuration information indicates that the first control information should include two resource indicators for the SRS resources. In some examples, the first control information indicates that a single SRS resource set is associated with a first uplink communication. In some examples, both the first and second uplink transmission parameter sets are based on the first resource indicator in the first control information, and are independent of the value of the second resource indicator in the first control information.

[0191] In some examples, the SRS configuration information indicates that the first control information should include two resource indicators for the SRS resources. In some examples, for the purpose of this method, the control information manager 1330 may be configured or otherwise supported to provide means for transmitting in the first control information an indication of the association of two SRS resource sets with the first uplink communication, and the control information manager 1330 may be configured or otherwise supported to provide means for wherein the first uplink transmission parameter set is based on a first resource indicator of the two resource indicators in the first control information and the second uplink transmission parameter set is based on a second resource indicator of the two resource indicators in the first control information.

[0192] In some examples, the SRS configuration information indicates that the first control information should include a single resource indicator for the SRS resource, and wherein both the first uplink transmission parameter set and the second uplink transmission parameter set are determined based on the single resource indicator in the first control information. In some examples, the SRI manager 1345 may be configured or otherwise support means for transmitting in the first control information an indication of the association of a single SRS resource set with first uplink communication, and wherein both the first uplink transmission parameter set and the second uplink transmission parameter set are based on the single resource indicator and the single SRS resource set in the first control information.

[0193] In some examples, the control information manager 1330 may be configured or otherwise supported to provide means for transmitting indications in the first control information regarding the association of two SRS resource sets with the first uplink communication. In some examples, the control information manager 1330 may be configured or otherwise supported to provide means for the first uplink transmission parameter set based on the single resource indicator in the first control information and a first mapping between the single resource indicator and the SRS resources of the first SRS resource set. In some examples, the control information manager 1330 may be configured or otherwise supported to provide means for the second uplink transmission parameter set based on the single resource indicator in the first control information and a second mapping between the single resource indicator and the SRS resources of the second SRS resource set.

[0194] In some examples, the SRS configuration information configures two or more different control information formats to include one resource indicator for the SRS resource or two resource indicators for the SRS resource.

[0195] In some examples, the first repeat set and the second repeat set of the first uplink communications are codebook-based physical uplink shared channel transmissions, and for each codebook-based resource indicator, one SRS resource is indicated within each SRS resource set. In some examples, the first repeat set and the second repeat set of the first uplink communications are non-codebook-based physical uplink shared channel transmissions, and for each non-codebook-based resource indicator, one or more SRS resources are indicated within each SRS resource set.

[0196] In some examples, the first repeated set of the first uplink communication and the second repeated set of the first uplink communication are transmitted via a codebook-based physical uplink shared channel, and the SRS configuration information indicates that the first control information should include the two resource indicators for the SRS resources, wherein each of the two resource indicators is mapped to an SRS resource with the same number of antenna ports within the associated SRS resource set. In some examples, the first repeated set of the first uplink communication and the second repeated set of the first uplink communication are transmitted via a codebook-based physical uplink shared channel, and the SRS configuration information indicates that the first control information should include two resource indicators for the SRS resources, wherein the i-th configured SRS resource in the first SRS resource set has the same number of antenna ports as the i-th configured SRS resource in the second SRS resource set.

[0197] In some examples, the first repeat set and the second repeat set of the first uplink communication are non-codebook-based physical uplink shared channel transmissions, and the SRS configuration information indicates that the first control information should include the two resource indicators for the SRS resources, wherein the first number of indicated SRS resources in the first SRS resource set is the same as the second number of indicated SRS resources in the second SRS resource set. In some examples, the SRS configuration information indicates that the first control information should include a single resource indicator for the SRS resources in the first and second SRS resource sets. In some examples, the first and second SRS resource sets have the same number of SRS resources, or the number of bits in the single resource indicator is determined based on the maximum number of SRS resources in either the first or second SRS resource set.

[0198] In some examples, to support the transmission of first control information, the SRI manager 1345 may be configured or otherwise supported to support means for transmitting a two-bit field within the first control information, the two-bit field indicating that the first uplink communication should use only the first SRS resource set, only the second SRS resource set, or both the first and second SRS resource sets, and determining which repeating set of the first uplink communication should use the first SRS resource set and determining another repeating set should use the second SRS resource set.

[0199] In some examples, in order to support the transmission of first control information, the SRI manager 1345 may be configured or otherwise support means for transmitting a single bit within the first control information, the single bit having a first bit value indicating that the first uplink communication will use one of the first SRS resource set or the second SRS resource set, or having a second bit value indicating that the first uplink communication will use both the first SRS resource set and the second SRS resource set.

[0200] In some examples, the first bit value provides a predetermined indication that a first uplink communication will use a first SRS resource set. In some examples, the first bit value uses SRS configuration information to configure it to indicate that the first uplink communication will use a first SRS resource set. In some examples, the first bit value indicates that a different information field in the first control information provides an indication of whether the first uplink communication will use a first SRS resource set or a second SRS resource set. In some examples, an indication that one of the first or second SRS resource sets is not used is provided by a reserved value for a resource indication of the associated SRS resource set.

[0201] Figure 14 A diagram of a system 1400 including device 1405 supporting multiple repetitive resource signaling technologies for uplink transmissions, according to various aspects of this disclosure, is shown. Device 1405 may be an example of device 1105, device 1205, or base station 105 as described herein, or a component including such devices. Device 1405 may wirelessly communicate with one or more base stations 105, UE 115, or any combination thereof. Device 1405 may include components for bidirectional voice and data communication, including components for transmitting and receiving communications, including a communication manager 1420, a network communication manager 1410, a transceiver 1415, an antenna 1425, a memory 1430, a code 1435, a processor 1440, and an inter-station communication manager 1445. These components may be in electronic communication or otherwise coupled (e.g., operational ground, communication ground, functional ground, electronic ground, electrical ground) via one or more buses (e.g., bus 1450).

[0202] The network communication manager 1410 can manage communication with the core network 130 (e.g., via one or more wired backhaul links). For example, the network communication manager 1410 can manage the delivery of data communication to client devices (such as one or more UEs 115).

[0203] In some cases, device 1405 may include a single antenna 1425. However, in other cases, device 1405 may have more than one antenna 1425, which may be capable of transmitting or receiving multiple wireless transmissions concurrently. Transceiver 1415 may communicate bidirectionally via one or more antennas 1425, wired or wireless links, as described herein. For example, transceiver 1415 may represent a wireless transceiver and be capable of bidirectional communication with another wireless transceiver. Transceiver 1415 may also include a modem for modulating packets and providing modulated packets to one or more antennas 1425 for transmission, and for demodulating packets received from one or more antennas 1425. Transceiver 1415, or transceiver 1415 and one or more antennas 1425, may be an example of transmitter 1115, transmitter 1215, receiver 1110, receiver 1210, or any combination thereof or components thereof as described herein.

[0204] Memory 1430 may include RAM and ROM. Memory 1430 may store computer-readable, computer-executable code 1435, including instructions that, when executed by processor 1440, cause device 1405 to perform the various functions described herein. Code 1435 may be stored in a non-transitory computer-readable medium, such as system memory or other types of memory. In some cases, code 1435 may not be directly executable by processor 1440, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein. In some cases, memory 1430 may, in particular, include a BIOS that controls basic hardware or software operations, such as interaction with peripheral components or devices.

[0205] Processor 1440 may include intelligent hardware devices (e.g., general-purpose processors, DSPs, CPUs, microcontrollers, ASICs, FPGAs, programmable logic devices, discrete gate or transistor logic components, discrete hardware components, or any combination thereof). In some cases, processor 1440 may be configured to use a memory controller to operate a memory array. In other cases, the memory controller may be integrated into processor 1440. Processor 1440 may be configured to execute computer-readable instructions stored in memory (e.g., memory 1430) to cause device 1405 to perform various functions (e.g., functions or tasks supporting multiple repetitive resource signaling technologies for uplink transmissions). For example, device 1405 or components thereof may include processor 1440 and memory 1430 coupled to processor 1440, wherein processor 1440 and memory 1430 are configured to perform the various functions described herein.

[0206] Inter-site communication manager 1445 manages communication with other base stations 105 and may include a controller or scheduler for cooperating with other base stations 105 to control communication with UE 115. For example, inter-site communication manager 1445 may coordinate the scheduling of transmissions to UE 115 for various interference mitigation techniques, such as beamforming or joint transmission. In some examples, inter-site communication manager 1445 may provide an X2 interface within LTE / LTE-A wireless communication network technology to facilitate communication between base stations 105.

[0207] Communication manager 1420 may support wireless communication at a base station according to the examples disclosed herein. For example, communication manager 1420 may be configured or otherwise support means for transmitting SRS configuration information to a UE, the SRS configuration information indicating whether control information for providing uplink permission to the UE includes one resource indicator for SRS resources or two resource indicators for SRS resources. Communication manager 1420 may be configured or otherwise support means for transmitting first control information to the UE, the first control information scheduling two or more repetitions of a first uplink communication and indicating the association between the two or more repetitions of the first uplink communication and a first SRS resource set, a second SRS resource set, or both. The communication manager 1420 may be configured or otherwise support means for determining a first set of uplink transmission parameters for a first set of repetitions of the first uplink communication and a second set of uplink transmission parameters for a second set of repetitions of the first uplink communication based on one or two resource indicators in the first control information and one or two SRS resource sets indicated by two or more repetitions associated with the first uplink communication in the first SRS resource set or the second SRS resource set. The communication manager 1420 may also be configured or otherwise support means for receiving the first set of repetitions of the first uplink communication using the first set of uplink transmission parameters and for receiving the second set of repetitions of the first uplink communication using the second set of uplink transmission parameters.

[0208] By including or configuring the communication manager 1420 according to the examples described herein, device 1405 can support multiple repetitions for configuring the UE to transmit uplink communications to multiple different TRPs, such that different repetitions can use transmission parameters suitable for the specific TRP associated with that repetition. Such techniques can allow for enhanced reliability of wireless communication and thus provide more efficient utilization of communication resources, reduced power consumption (through reduced retransmissions), reduced latency (through reduced retransmissions), and more efficient utilization of communication resources. Furthermore, such techniques provide the flexibility to schedule uplink communications with repetitions based on one or more SRS resource sets, which can enhance network efficiency by efficiently scheduling uplink communications according to available network and radio resources.

[0209] In some examples, the communication manager 1420 may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise cooperating with the transceiver 1415, one or more antennas 1425, or any combination thereof. Although the communication manager 1420 is described as a separate component, in some examples, one or more functions described with reference to the communication manager 1420 may be supported or performed by the processor 1440, memory 1430, code 1435, or any combination thereof. For example, code 1435 may include instructions executable by the processor 1440 to cause the device 1405 to perform various aspects of multiple repetitive resource signaling techniques for uplink transmissions as described herein, or the processor 1440 and memory 1430 may be otherwise configured to perform or support such operations.
