Description

[0001] public domain

[0002] Aspects of the present disclosure relate generally to wireless communications, and more particularly to techniques and apparatus for uplink communication repetition using multiple control channel resources in a single time slot.

[0003] background

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless communication network may include several base stations (BSs) capable of supporting communications for several user equipment (UEs). User equipment (UEs) may communicate with the base stations (BSs) via downlinks and uplinks. The downlink (or forward link) refers to the communication link from the BS to the UE, while the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit / receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies.

[0007] Overview

[0008] In some aspects, a wireless communication method performed by a user equipment (UE) may include: identifying multiple physical uplink control channel (PUCCH) resources to be used for multiple repetitions of uplink communication in a single time slot; and using one or more of the multiple PUCCH resources, or one or more other resources, to transmit one or more of the multiple repetitions of the uplink communication in the same time slot based at least in part on identifying the multiple PUCCH resources.

[0009] In some aspects, a wireless communication method performed by a base station may include: determining multiple PUCCH resources of multiple repetitions to be used for uplink communication of a UE in a single time slot; and transmitting an indication of the multiple PUCCH resources to the UE so that the UE can use one or more of the multiple PUCCH resources, or one or more other resources, to transmit one or more of the multiple repetitions in the same time slot.

[0010] In some aspects, a UE for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: identify multiple PUCCH resources to be used for multiple repetitions of uplink communication in a single time slot; and transmit one or more of the multiple repetitions of the uplink communication in the same time slot using one or more of the multiple PUCCH resources or one or more other resources based at least in part on identifying the multiple PUCCH resources.

[0012] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, may cause the one or more processors to: identify multiple PUCCH resources to be used for multiple repetitions of uplink communication in a single time slot; and transmit one or more of the multiple repetitions of the uplink communication in the same time slot using one or more of the multiple PUCCH resources or one or more other resources based at least in part on identifying the multiple PUCCH resources.

[0013] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication.

[0028] Detailed description

[0029] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. Specifically, these aspects are provided to make the present disclosure thorough and complete, and they will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, regardless of whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods that are practiced using a supplement to the various aspects of the disclosure set forth herein or other other structures, functionality, or structure and functionality. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0030] Several aspects of telecommunications systems will now be presented with reference to various devices and techniques. These devices and techniques are described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0031] It should be noted that although various aspects may be described herein using terminology generally associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applicable in communication systems based on other generations, such as 5G and later generations, including NR technology.

[0032] Figure 1 1 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station is an entity that communicates with user equipment (UE) and may also be referred to as a base station, NR base station, node B, gNB, 5G node B (NB), access point, transmit reception point (TRP), etc. Each base station may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a base station and / or the base station subsystem serving that coverage area, depending on the context in which the term is used.

[0033] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in FIG, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB," "base station," "NR BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0034] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections, virtual networks, etc.) using any suitable transport network.

[0035] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , relay station 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station may also be referred to as a relay BS, relay base station, relay, or the like.

[0036] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0037] The network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. These BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0038] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0039] Some UEs may be considered machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, and the like, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included within a housing that houses components of UE 120, such as a processor component, a memory component, and the like. In some aspects, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, and the like.

[0040] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, air interface, etc. A frequency may also be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0041] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary) using one or more sidelink channels. For example, the UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this scenario, the UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0042] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0043] Figure 2A block diagram shows a design 200 of a base station 110 and a UE 120, which may be Figure 1 One for each base station and one for each UE in . Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0044] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)). A transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, as applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and frequency upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively. According to various aspects described in greater detail below, position coding may be utilized to generate synchronization signals to convey additional information.

[0045] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0046] On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by MIMO detector 236, if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Network controller 130 may include communication unit 294, controller / processor 290, and memory 292.

[0047] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with uplink communication repetition using multiple control channel resources in a single time slot, as described in more detail elsewhere herein. Figure 2 Any other component of the may perform or direct e.g. Figure 7 The process of 700 Figure 8 800, and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, interpretation, etc.) by one or more processors of base station 110 and / or UE 120, may perform or direct, for example, Figure 7 The process of 700 Figure 8 The process 800 of , and / or operations of other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, interpreting instructions, etc. The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0048] In some aspects, the UE 120 may include: means for identifying a plurality of physical uplink control channel (PUCCH) resources to be used for a plurality of repetitions of an uplink communication in a single time slot; means for transmitting one or more of the plurality of repetitions of the uplink communication using one or more of the plurality of PUCCH resources, or one or more other resources, in the same time slot based at least in part on identifying the plurality of PUCCH resources; and the like. In some aspects, such means may include in conjunction with Figure 2 One or more components of the UE 120 are depicted, such as the controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0049] In some aspects, the base station 110 may include: means for determining a plurality of PUCCH resources of a plurality of repetitions to be used for uplink communications of a UE in a single time slot; means for transmitting an indication of the plurality of PUCCH resources to the UE to enable the UE to use one or more of the plurality of PUCCH resources, or one or more other resources, to transmit one or more of the plurality of repetitions in the same time slot; and the like. In some aspects, such means may include in conjunction with Figure 2One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and so forth.

[0050] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0051] Figure 3 is a diagram illustrating an example 300 of a frame structure in a wireless communication network in accordance with various aspects of the present disclosure. Figure 3 The frame structure shown in is used for frequency division duplex (FDD) in telecommunication systems such as LTE, NR, etc. The transmission timeline for each of the downlink and uplink may be divided into units of radio frames (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z ≥ 1) subframes (e.g., with indices 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., in Figure 3 Each subframe 2 is shown in m time slots, where m is an index of the parameter design for transmission, such as 0, 1, 2, 3, 4, etc.). Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., Figure 3 ), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two slots (e.g., when m=1), the subframe may include 2L symbol periods, where the 2L symbol periods in each subframe may be assigned indices 0 to 2L–1. In some aspects, the scheduling unit for FDD may be frame-based, subframe-based, slot-based, minislot-based, symbol-based, etc.

[0052] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described in Figure 3 Examples described.

[0053] Wireless communication devices (such as UEs, base stations, and TRPs) can communicate with each other using repetition of communication (e.g., by transmitting the same communication multiple times). For example, for uplink communication, the base station can indicate multiple repetitions of physical uplink control channel (PUCCH) resources to be used by the UE for uplink communication. The base station can indicate multiple repetitions of PUCCH resources for uplink communication in one time slot, or multiple repetitions of PUCCH resources to be used by the UE in multiple time slots (e.g., using the same time domain resources in each time slot).

[0054] In some cases, it may be beneficial for a UE to use multiple PUCCH resources that can be received by different receivers (e.g., different antennas, panels, TRPs, BSs, etc.) to convey multiple repetitions of uplink communications, thereby improving the communication performance of the UE. In addition, it may be beneficial for the UE to convey multiple repetitions of uplink communications in a single time slot to reduce latency. However, the UE may not be able to use multiple PUCCH resources in a single time slot to convey repetitions of communications. As a result, diversity and / or reliability of communications may be compromised. Some techniques and apparatus described herein enable a UE to use multiple PUCCH resources in a single time slot to convey multiple repetitions of uplink communications.

[0055] Figure 4 is a diagram illustrating an example 400 of uplink communication repetition using multiple control channel resources in a single time slot in accordance with various aspects of the present disclosure. Figure 4 As shown in , a base station (eg, BS 110 ) and a user equipment (eg, UE 120 ) may communicate with each other in a wireless network (eg, wireless network 100 ).

[0056] As indicated by reference numeral 405, BS 110 may configure multiple PUCCH resource sets. BS 110 may configure multiple PUCCH resource sets using a radio resource control (RRC) protocol. For example, in some aspects, BS 110 may configure four PUCCH resource sets. Each PUCCH resource set may be configured with a resource set identifier and a maximum payload size for uplink communications for one or more PUCCH resources included in the PUCCH resource set.

[0057] The multiple PUCCH resource sets may be configured to indicate one or more PUCCH resource clusters. A PUCCH resource cluster may indicate one or more PUCCH resources (e.g., a PUCCH resource cluster may identify one PUCCH resource, two PUCCH resources, three PUCCH resources, etc.). Each of the one or more PUCCH resources may be associated with specific resources (e.g., a number of resource blocks, a number of symbols, etc.). In some aspects, the one or more PUCCH resources indicated by the PUCCH resource cluster are in the same time slot.

[0058] In some aspects, each PUCCH resource set may indicate a maximum number of PUCCH resource clusters (e.g., a maximum of 8 PUCCH resource clusters). In some aspects, a PUCCH resource set among one or more PUCCH resource sets may have a higher maximum number of PUCCH resource clusters (e.g., a maximum of 32 PUCCH resource clusters) than all other PUCCH resource sets (e.g., a maximum of 8 PUCCH resource clusters).

[0059] As indicated by reference numeral 410, BS 110 may transmit an indication of the configuration of the plurality of PUCCH resource sets. For example, the configuration of the plurality of PUCCH resource sets may be an RRC configuration. BS 110 may transmit the indication of the configuration of the plurality of PUCCH resource sets using the RRC protocol.

[0060] As indicated by reference numeral 415, BS 110 may determine, in a single time slot, a plurality of repetitions of a plurality of PUCCH resources to be used by UE 120 for uplink communication. In some aspects, the plurality of PUCCH resources may not overlap in the time domain (e.g., the plurality of PUCCH resources may be time division multiplexed). In some aspects, the plurality of PUCCH resources may overlap in the time domain (e.g., partially overlap, fully overlap, etc.) (e.g., the plurality of PUCCH resources may be frequency division multiplexed).

[0061] In some aspects, the uplink communication may be an uplink communication scheduled by a downlink communication (e.g., scheduled by downlink control information (DCI) indicated in the downlink communication). For example, the uplink communication may be a channel state information (CSI) communication, a hybrid automatic repeat request acknowledgement (HARQ-ACK) communication, a scheduling request (SR) communication, etc. In some aspects, the uplink communication occurs periodically (e.g., without being scheduled by a downlink communication).

[0062] As indicated by reference numeral 420, BS 110 may transmit an indication of the multiple PUCCH resources. The indication of the multiple PUCCH resources may enable UE 120 to transmit multiple repetitions of the uplink communication using one or more of the multiple PUCCH resources, or one or more other resources (e.g., if UE 120 performs any multiplexing, as described herein), in the same time slot. In some aspects, the indication of the multiple PUCCH resources may be included in the downlink communication that schedules the multiple repetitions of the uplink communication. For example, the DCI that schedules the PDSCH (e.g., DCI formats 1_0, 1_1, 1_2) may also schedule HARQ-Ack transmissions for acknowledging the scheduled PDSCH. In some aspects, the indication of the multiple PUCCH resources may be indicated in the RRC configuration (e.g., in the case of periodic uplink communication).

[0063] In some aspects, downlink communications including an indication of the plurality of PUCCH resources and scheduling uplink communications may include a timing indicator, a PUCCH resource indicator (PRI), etc. In some aspects, downlink communications may be associated with a control resource set (CORESET). A CORESET may include several control channel element indices.

[0064] As indicated by reference numeral 425, UE 120 may identify multiple repetitions of multiple PUCCH resources to be used for uplink communication in a single time slot. For example, UE 120 may identify the multiple PUCCH resources based at least in part on an indication of the multiple PUCCH resources received by UE 120.

[0065] UE 120 may identify a PUCCH resource set from a plurality of PUCCH resource sets configured by BS 110 based at least in part on a payload size of the uplink communication. For example, UE 120 may compare the payload size of the uplink communication with a maximum payload size associated with each of the plurality of PUCCH resource sets. In some aspects, the payload size of the uplink communication may be a payload size of uplink control information (UCI) of the uplink communication. The UE may identify the PUCCH resource set from the plurality of PUCCH resource sets based at least in part on a comparison of the payload size of the uplink communication with the maximum payload size (e.g., based at least in part on the payload size of the uplink communication being less than the maximum payload size of the PUCCH resource set). In some aspects, the payload size of the uplink communication may be the payload size of the uplink communication after UE 120 performs a multiplexing operation, as described below.

[0066] In some aspects, the UE 120 may identify a PUCCH resource cluster from one or more PUCCH resource clusters indicated by the PUCCH resource set based at least in part on a PUCCH resource indicator (PRI) received in a downlink communication that scheduled the uplink communication. In some aspects, the PRI may be capable of indicating the same number of values ​​as the number of resource clusters indicated by the PUCCH resource set. For example, the PUCCH resource set may indicate eight PUCCH resource clusters. The PRI may be 3 bits in size to enable the PRI to indicate eight values. In this case, the UE 120 may identify the PUCCH resource cluster based at least in part on the PRI value.

[0067] In some aspects, the PUCCH resource set may indicate a higher number of resource clusters than the number of values ​​that the PRI can indicate (e.g., the PUCCH resource set may indicate 32 PUCCH resource clusters, while the PRI may be capable of indicating 8 values). In this case, the UE 120 may identify the PUCCH resource cluster based at least in part on at least one of a PRI value, a first control channel element (CCE) index for a downlink communication indicating the PRI, or a number of CCEs included in a CORESET in which the UE 120 received a downlink communication indicating the PRI. For example, the PUCCH resource cluster may be derived using an equation that utilizes the PRI value, the first CCE index for the downlink communication, and the number of CCEs included in the CORESET.

[0068] In some aspects, the PUCCH resource cluster may indicate multiple PUCCH resources in a single time slot. UE 120 may identify the time slot based at least in part on a timing indicator indicated in a downlink communication that schedules the uplink communication (e.g., the timing indicator may indicate that the time slot is a number of time slots later than when the downlink communication was received). If UE 120 determines that the PUCCH resource cluster indicates multiple PUCCH resources, UE 120 may transmit a repetition of the uplink communication in each PUCCH resource indicated in the PUCCH resource cluster. For example, if the PUCCH resource cluster indicates a first PUCCH resource and a second PUCCH resource, UE 120 may use the first PUCCH resource to schedule the first repetition of the uplink communication and use the second PUCCH resource to schedule the second repetition of the uplink communication.

[0069] In some aspects, the multiple repetitions of the uplink communication may use different spatial relationships (e.g., different beams, different power control parameters, etc.) For example, BS 110 may transmit an activation command to UE 120 (e.g., via a media access control element (MAC-CE)) to activate a first spatial relationship for a first PUCCH resource in the plurality of PUCCH resources and to activate a second spatial relationship for a second PUCCH resource in the plurality of PUCCH resources.

[0070] In some aspects, the multiple PUCCH resources may be activated using a spatial relationship having different closed-loop index values. UE 120 may apply a transmit power control (TPC) command received in a downlink communication scheduling the uplink communication to different closed-loop index values. For example, UE 120 may identify a first PUCCH resource having a first closed-loop index value among the multiple PUCCH resources and a second PUCCH resource having a second closed-loop index value among the multiple PUCCH resources. The UE may apply the TPC command to the first closed-loop index value and the second closed-loop index value. In some aspects, UE 120 may apply the TPC command to only the first closed-loop index value.

[0071] In some aspects, BS 110 may configure the DCI for the downlink communication that schedules the uplink communication to indicate multiple TPC commands. For example, the downlink communication may indicate a first TPC command to be applied to a first closed-loop index value and a second TPC command to be applied to a second closed-loop index value. BS 110 may configure a corresponding field in the DCI for each TPC command. In some aspects, BS 110 may configure a single field in the DCI to indicate multiple TPC commands (e.g., the first TPC command and the second TPC command).

[0072] As in Figure 4 , and indicated by reference numeral 430, UE 120 may determine whether to drop one or more of a plurality of repetitions of the uplink communication based at least in part on determining that one or more of the plurality of PUCCH resources associated with the uplink communication overlap in the time domain with at least one other PUCCH resource of a different uplink communication. For example, UE 120 may determine a priority associated with each type of uplink communication that UE 120 is capable of transmitting. In some aspects, the priority of the uplink communication types may be (from highest priority to lowest priority): HARQ-ACK > SR > CSI. In some aspects, the CSI communications may include higher priority CSI communications and lower priority CSI communications. In this case, the priority of the uplink communication types may be (from highest priority to lowest priority): HARQ-ACK > SR > higher priority CSI > lower priority CSI.

[0073] In some aspects, the UE 120 may determine whether to discard one or more of the multiple repetitions of the uplink communication based at least in part on comparing the uplink communication type of the uplink communication with the uplink communication type of a different uplink communication. In some aspects, the UE 120 may discard the uplink communication having a lower priority uplink communication type (e.g., the uplink communication or the different uplink communication). For example, if the repetition of the uplink communication is an SR communication and the different communication is a HARQ-ACK communication, the UE 120 may discard the repetition of the uplink communication that overlaps with at least one other PUCCH resource of the different uplink communication in the time domain. In some aspects, if the one or more repetitions of the uplink communication do not overlap with at least one other PUCCH resource of the different uplink communication in the time domain, the UE 120 may not discard the non-overlapping repetition of the uplink communication.

[0074] In some aspects, UE 120 may determine that the uplink communication and a different uplink communication have the same uplink communication type. In this case, UE 120 may compare the start time of one or more of the multiple repetitions of the uplink communication with the start time of the different uplink communication. The start time of one or more of the multiple repetitions of the uplink communication may be determined based at least in part on the start time of a repetition that overlaps with the different uplink communication or based at least in part on the start time of the first repetition of the multiple repetitions of the uplink communication. In some aspects, UE 120 may discard the uplink communication with the later start time (e.g., the uplink communication or the different uplink communication).

[0075] In some aspects, when the uplink communication and the different uplink communication have the same uplink communication type, the UE 120 may compare the number of repetitions of the multiple repetitions of the uplink communication in the time slot with the number of repetitions of the different uplink communication in the time slot. In some aspects, the number of repetitions of the multiple repetitions of the uplink communication may be the total number of repetitions or the number of repetitions that overlap with the different uplink communication in the time domain. In some aspects, the UE 120 may discard the uplink communication with the larger number of repetitions in the time slot (e.g., the uplink communication or the different uplink communication). In some aspects, the UE 120 may discard the uplink communication with the lower number of repetitions in the time slot (e.g., the uplink communication or the different uplink communication).

[0076] In some aspects, UE 120 may determine that one or more of the plurality of PUCCH resources overlap in the time domain with at least one physical uplink shared channel (PUSCH) resource of an associated different uplink communication. UE 120 may drop the different uplink communication based at least in part on determining that one or more of the plurality of PUCCH resources overlap in the time domain with the at least one PUSCH resource.

[0077] As indicated by reference numeral 435, UE 120 may determine whether to multiplex one or more of the multiple repetitions of the uplink communication with the one or more different uplink communications based at least in part on determining that the one or more different uplink communications are scheduled in one or more resources that overlap with at least one of the multiple PUCCH resources in the time domain. In some aspects, UE 120 may determine that the one or more resources that overlap with at least one of the multiple PUCCH resources in the time domain are one or more PUCCH resources. UE 120 may multiplex the uplink communication with the one or more different uplink communications based at least in part on determining that the one or more resources that overlap with at least one of the multiple PUCCH resources in the time domain are PUCCH resources. As a result, all repetitions of the uplink communication may include the uplink communication and payloads of the different uplink communications (e.g., may include UCI for the uplink communication and UCI for the different uplink communications). UE 120 may determine new PUCCH resources (which may or may not be the same as the originally identified multiple PUCCH resources) using the new payload size for the multiplexed PUCCH communication in a similar manner as described above (e.g., by identifying a PUCCH resource cluster from the identified PUCCH resource set).

[0078] In some aspects, the UE 120 may determine that the one or more resources overlapping with at least one of the multiple PUCCH resources in the time domain are one or more resources for a PUSCH transmission. In some aspects, the UE 120 may determine that the PUSCH transmission includes multiple PUSCH repetitions. In some aspects, the UE 120 may multiplex the uplink communication (e.g., all repetitions for the uplink) with the multiple PUSCH repetitions based at least in part on determining that the PUSCH transmission includes multiple PUSCH repetitions. In some aspects, the UE 120 may multiplex the uplink communication with one or more PUSCH repetitions overlapping with at least one of the multiple PUCCH resources in the time domain (e.g., such that only the overlapping PUSCH transmissions include the payload of the uplink communication (e.g., UCI for the uplink communication)) based at least in part on determining that the PUSCH transmission includes multiple PUSCH repetitions.

[0079] In some aspects, the UE 120 may drop one or more of the plurality of repetitions of the uplink communication (e.g., all repetitions of the uplink communication) based at least in part on determining that the PUSCH transmission includes a plurality of PUSCH repetitions. In some aspects, the UE 120 may drop one or more repetitions of the uplink communication associated with at least one of the plurality of PUCCH resources that overlap with one or more PUSCH repetitions in the time domain based at least in part on determining that the PUSCH transmission includes a plurality of PUSCH repetitions.

[0080] As indicated by reference numeral 440, UE 120 may transmit one or more repetitions of the uplink communication and / or one or more multiplexed communications in a single time slot to BS 110. For example, UE 120 may transmit the multiple repetitions of the uplink communication in a single time slot using the multiple PUCCH resources after determining whether to drop or multiplex one or more of the multiple repetitions. In some aspects, UE 120 may transmit the one or more repetitions of the uplink communication in a single time slot using resources different from the multiple PUCCH resources (e.g., after performing multiplexing).

[0081] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described in Figure 4 Examples described.

[0082] Figure 5 5 is a diagram illustrating an example 500 of uplink communication repetition using multiple control channel resources in a single time slot according to various aspects of the present disclosure. As shown, a transmission timeline for an uplink may include one or more time slots, such as a first time slot (e.g., time slot 510), a second time slot (e.g., time slot 520), and a third time slot (e.g., time slot 530). Time slot 510, time slot 520, and / or time slot 530 may be different time slots in the same transmission timeline for the uplink. In some aspects, time slot 510, time slot 520, and / or time slot 530 may represent the same time slot in different transmission timelines for the uplink. A block in time slot 510, time slot 520, and / or time slot 530 may represent a resource (e.g., a PUCCH resource, a resource for PUSCH transmission, etc.).

[0083] In some aspects, the user equipment (e.g., UE 120) may compare the uplink communication types of the uplink communications in each time slot to determine which (if any) uplink communications to discard. In some aspects, the UE 120 may be similar to the above description of Figure 4A similar approach as described above is used to determine which (if any) uplink communications to discard. Time slot 510, time slot 520, and time slot 530 are provided as examples only. Other time slots may include more uplink communications, fewer uplink communications, different uplink communications, etc.

[0084] For example, as shown in time slot 510, UE 120 may identify multiple (e.g., two) repetitions of an uplink communication (e.g., PUCCH 1) using multiple (e.g., two) PUCCH resources in time slot 510. The UE may identify PUCCH 1 as a scheduling request (SR) communication. UE 120 may identify a second uplink communication (e.g., PUCCH 2) as a hybrid automatic repeat request acknowledgement (HARQ-ACK) communication. UE 120 may identify a third uplink communication (e.g., PUCCH 3) as a channel state information (CSI) communication. UE 120 may identify an uplink data transmission (e.g., PUSCH 1).

[0085] UE 120 may determine that the first repetition of PUCCH 1 (e.g., SR) should be dropped based at least in part on that PUCCH resources of the first repetition of PUCCH 1 overlap with PUCCH resources of PUCCH 2 in the time domain and based at least in part on that the uplink communication type of PUCCH 2 (e.g., HARQ-ACK) has a higher priority than the uplink communication type (e.g., SR) of PUCCH 1. UE 120 may determine that PUCCH 3 should be dropped based at least in part on that PUCCH resources of PUCCH 3 overlap with at least one repetition of PUCCH 1 in the time domain and based at least in part on that the uplink communication type of PUCCH 1 (e.g., SR) has a higher priority than the uplink communication type of PUCCH 3 (e.g., CSI). UE 120 may determine that PUSCH 1 should be dropped based at least in part on resources of PUSCH 1 overlapping with at least one repetition of PUCCH 1 in the time domain and based at least in part on determining that resources of PUSCH 1 are to be used for PUSCH transmission. As a result, UE 120 may transmit PUCCH 2 and a second repetition of PUCCH 1 in time slot 510 after determining which uplink communications should be dropped (e.g., as shown in FIG. 2 ). Figure 5 following the top arrow in the ).

[0086] As shown in time slot 520, UE 120 may identify multiple (e.g., two) repetitions of an uplink communication (e.g., PUCCH 1) using multiple (e.g., two) PUCCH resources in time slot 520. The UE may identify PUCCH 1 as a HARQ-ACK communication. UE 120 may identify multiple (e.g., two) repetitions of another uplink communication (e.g., PUCCH 2) using multiple (e.g., two) PUCCH resources in time slot 520. UE 120 may identify PUCCH 2 as an SR communication. UE 120 may determine that the second repetition of PUCCH 2 (e.g., SR) should be dropped based at least in part on the PUCCH resources of the second repetition of PUCCH 2 overlapping with at least one repetition of PUCCH 1 in the time domain and based at least in part on the uplink communication type of PUCCH 1 (e.g., HARQ-ACK) having a higher priority than the uplink communication type of PUCCH 2 (e.g., SR). UE 120 may determine that the first repetition of PUCCH 2 should not be dropped based at least in part on the PUCCH resources of the first repetition of PUCCH 2 not overlapping in the time domain with at least one PUCCH resource of one or more repetitions of PUCCH 1 (or any other PUCCH resource of another uplink communication). As a result, UE 120 may transmit the first repetition of PUCCH 2 and two repetitions of PUCCH 1 in time slot 520 after determining which uplink communications should be dropped (e.g., as shown in FIG. 5 ). Figure 5 shown after the middle arrow in the figure).

[0087] As shown in time slot 530, UE 120 may identify multiple (e.g., three) repetitions of an uplink communication (e.g., PUCCH 1) using multiple (e.g., three) PUCCH resources in time slot 530. The UE may identify that PUCCH 1 is a CSI communication. UE 120 may identify multiple (e.g., three) repetitions of another uplink communication (e.g., PUCCH 2) using multiple (e.g., three) PUCCH resources in time slot 530. UE 120 may identify that PUCCH 2 is an SR communication. UE 120 may determine that the first two repetitions of PUCCH 1 should be dropped based at least in part on the PUCCH resources of the first two repetitions of PUCCH 1 overlapping in the time domain with at least one PUCCH resource of one or more repetitions of PUCCH 2 and based at least in part on the uplink communication type (e.g., SR) of PUCCH 2 having a higher priority than the uplink communication type (e.g., CSI) of PUCCH 1. UE 120 may determine that the last repetition of PUCCH 1 should not be dropped based at least in part on the PUCCH resource of the last repetition of PUCCH 1 not overlapping in the time domain with at least one PUCCH resource of one or more repetitions of PUCCH 2 (or any other PUCCH resource for uplink communications). As a result, UE 120 may transmit all repetitions of PUCCH 2 and the last repetition of PUCCH 1 in time slot 530 after determining which uplink communications should be dropped (e.g., as shown in FIG. 5 ). Figure 5 following the bottom arrow in the ).

[0088] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described in Figure 5 Examples described.

[0089] Figure 6 6 is a diagram illustrating an example 600 of uplink communication repetition using multiple control channel resources in a single time slot in accordance with various aspects of the present disclosure. As shown, a transmission timeline for an uplink may include one or more time slots, such as a first time slot (e.g., time slot 610), a second time slot (e.g., time slot 620), and a third time slot (e.g., time slot 630). Time slot 610, time slot 620, and / or time slot 630 may be different time slots in the same transmission timeline for the uplink. In some aspects, time slot 610, time slot 620, and / or time slot 630 may represent the same time slot in different transmission timelines for the uplink. A block in time slot 610, time slot 620, and / or time slot 630 may represent a resource (e.g., a PUCCH resource, a resource for a PUSCH transmission, etc.).

[0090] In some aspects, a user equipment (e.g., UE 120) may determine in each time slot whether PUCCH resources for different uplink communications overlap in the time domain to determine which (if any) uplink communications to multiplex. In some aspects, UE 120 may be similar to the above with respect to Figure 4 A similar approach as described above can be used to determine which (if any) uplink communications to multiplex. Time slot 610, time slot 620, and / or time slot 630 are provided as examples only. Other time slots may include more uplink communications, fewer uplink communications, different uplink communications, etc.

[0091] For example, as shown in time slot 610, UE 120 may identify multiple (e.g., two) repetitions of an uplink communication (e.g., PUCCH 1) using multiple (e.g., two) PUCCH resources in time slot 610. UE 120 may determine that the payload of PUCCH 1 is uplink control information (UCI) 1. UE 120 may identify a second uplink communication (e.g., PUCCH 2) having a payload of UCI 2. UE 120 may determine that PUCCH 1 and PUCCH 2 should be multiplexed based at least in part on determining that the PUCCH resources of PUCCH 2 overlap in the time domain with at least one PUCCH resource of the multiple repetitions of PUCCH 1. As a result, UE 120 may transmit two repetitions of PUCCH 1 (e.g., as shown in time slot 610) after determining which uplink communications should be multiplexed (and multiplexing the uplink communications). Figure 6 In some aspects, the payloads of all multiple repetitions of PUCCH 1 after multiplexing may include UCI 1 and UCI 2 (e.g., because all repetitions for uplink communication may have the same payload). In some aspects, the PUCCH resources of the multiple repetitions of PUCCH 1 may change after multiplexing (e.g., based at least in part on a payload change for PUCCH 1, as described above with respect to FIG. Figure 4 described).

[0092] As shown in time slot 620, UE 120 may identify multiple (e.g., two) repetitions of uplink communications (e.g., PUCCH 1) in time slot 620 using multiple (e.g., two) PUCCH resources. UE 120 may determine that the payload of PUCCH 1 is UCI 1. UE 120 may identify multiple (e.g., two) repetitions of PUSCH transmissions (e.g., PUSCH 1) in time slot 620 using multiple (e.g., two) PUSCH resources (multiple consecutive sets of OFDM symbols for transmission of the multiple PUSCH repetitions). The UE may determine that PUSCH 1 should not be dropped based at least in part on PUSCH 1 having multiple repetitions. UE 120 may determine that PUCCH 1 and PUSCH 1 should be multiplexed based at least in part on determining that at least one PUCCH resource of the multiple repetitions of PUCCH 1 overlaps in the time domain with at least one symbol of any repetition of PUSCH 1. As a result, UE 120 may transmit the two repetitions of PUSCH 1 after determining which uplink communications should be multiplexed (and multiplexing those uplink communications) (e.g., as Figure 6 In some aspects, the payload of all repetitions of PUSCH 1 after multiplexing may include UCI 1 (e.g., from PUCCH 1).

[0093] In some aspects, as illustrated by time slot 630, UE 120 may determine that the second repetition of PUCCH 1 should be multiplexed with the first repetition of PUSCH 1 based at least in part on the PUCCH resources of the second repetition of PUCCH 1 overlapping in the time domain with at least one symbol of the first repetition of PUSCH 1. As a result, UE 120 may transmit the first repetition of PUCCH 1 (including UCI 1) and both repetitions of PUSCH 1 (e.g., as shown in FIG630 ) after determining which uplink communications should be multiplexed (and multiplexing those uplink communications). Figure 6 After multiplexing, the first repetition of PUSCH 1 may include UCI 1.

[0094] In some aspects, UE 120 may determine that all repetitions of PUCCH 1 should be dropped based at least in part on one or more PUCCH resources in the multiple repetitions of PUCCH 1 overlapping in the time domain with one or more resources of the multiple repetitions of PUSCH 1. In some aspects, UE 120 may determine that overlapping repetitions of PUCCH 1 should be dropped (e.g., repetitions of PUCCH 1 associated with PUCCH resources that overlap in the time domain with one or more resources of the multiple repetitions of PUSCH 1).

[0095] As indicated above, Figure 6 are provided as examples. Other examples may differ from those described in Figure 6 Examples described.

[0096] Figure 7 7 is a diagram illustrating an example process 700, performed, for example, by a user equipment, in accordance with various aspects of the present disclosure. Example process 700 is an example in which a user equipment (e.g., user equipment 120, etc.) uses multiple uplink control channel resources in a single time slot to perform operations associated with uplink communication repetition.

[0097] like Figure 7 As shown in , in some aspects, process 700 may include identifying multiple repetitions of multiple PUCCH resources to be used for uplink communications in a single time slot (block 710). For example, a user equipment (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may identify multiple repetitions of multiple PUCCH resources to be used for uplink communications in a single time slot, as described above.

[0098] As in Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include transmitting one or more of the plurality of repetitions of the uplink communication in the same time slot using one or more of the plurality of PUCCH resources, or one or more other resources, based at least in part on identifying the plurality of PUCCH resources (block 720). For example, the user equipment (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may transmit one or more of the plurality of repetitions of the uplink communication in the same time slot using one or more of the plurality of PUCCH resources, or one or more other resources, based at least in part on identifying the plurality of PUCCH resources, as described above.

[0099] Process 700 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0100] In a first aspect, the plurality of PUCCH resources are time division multiplexed.

[0101] In a second aspect, alone or in combination with the first aspect, the multiple PUCCH resources overlap in the time domain.

[0102] In a third aspect, alone or in combination with one or more of the first and second aspects, the multiple PUCCH resources are determined at least in part based on the configuration of multiple PUCCH resource sets, wherein the multiple PUCCH resource sets are configured through a radio resource control protocol.

[0103] In a fourth aspect, alone or in combination with one or more of the first to third aspects, process 700 includes identifying a PUCCH resource set from the plurality of PUCCH resource sets based at least in part on a payload size of the uplink communication.

[0104] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, a PUCCH resource set among the plurality of PUCCH resource sets indicates one or more PUCCH resource clusters.

[0105] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, a PUCCH resource cluster of the one or more PUCCH resource clusters indicates one or more PUCCH resources.

[0106] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, process 700 includes identifying a PUCCH resource cluster from the one or more PUCCH resource clusters based at least in part on a PUCCH resource indicator.

[0107] In an eighth aspect, alone or in combination with one or more of aspects one to seven, process 700 includes identifying a PUCCH resource cluster from the one or more PUCCH resource clusters based at least in part on at least one of: a PUCCH resource indicator, a first control channel element index of a downlink communication indicating the PUCCH resource indicator, or the number of control channel element indices indicated in a control resource set in which a downlink communication indicating the PUCCH resource indicator is received.

[0108] In a ninth aspect, alone or in combination with one or more of aspects one to eight, process 700 includes identifying a PUCCH resource cluster from the one or more PUCCH resource clusters, wherein the PUCCH resource cluster indicates the multiple PUCCH resources, wherein transmitting one or more of the multiple repetitions of the uplink communication includes: using the multiple PUCCH resources indicated by the PUCCH resource cluster to transmit one or more of the multiple repetitions.
