Description

[0001] Public domain

[0002] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for beam hopping within a single physical uplink control channel resource.

[0003] background

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support 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 (BS) that can support communication of several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receive Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different user equipment to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set 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 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 in 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 method of wireless communication performed by a user equipment (UE) may include receiving an activation command to activate multiple spatial relationships for a single physical uplink control channel (PUCCH) resource; and communicating using the multiple spatial relationships in the single PUCCH resource.

[0009] In some aspects, a wireless communication method performed by a base station (BS) may include determining multiple spatial relationships to be activated for a UE in a single PUCCH resource; and transmitting an activation command to the UE to activate the multiple spatial relationships for the single PUCCH resource.

[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 receive an activation command to activate multiple spatial relationships for a single PUCCH resource; and communicate in the single PUCCH resource using the multiple spatial relationships.

[0011] In some aspects, a BS 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 determine a plurality of spatial relationships to be activated for a UE in a single PUCCH resource; and transmit an activation command to the UE to activate the plurality of spatial relationships for the single PUCCH resource.

[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: receive an activation command to activate multiple spatial relationships for a single PUCCH resource; and communicate in the single PUCCH resource using the multiple spatial relationships.

[0013] 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 BS, may cause the one or more processors to: determine multiple spatial relationships to be activated for a UE in a single PUCCH resource; and transmit an activation command to the UE to activate the multiple spatial relationships for the single PUCCH resource.

[0025] Detailed Description

[0026] 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. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it 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, 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 practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0027] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "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.

[0028] It should be noted that although various aspects may be described herein using terminology typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations, such as 5G and later generations, including NR technologies.

[0029] 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 (BSs) 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, B node, gNB, 5G B node (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0030] 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 1In the example shown in , 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. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0031] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to 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.

[0032] 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 , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0033] 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 effects 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).

[0034] A 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. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0035] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may be a cellular phone (e.g., a smart phone), 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 (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, 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, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0036] Some UEs may be considered as 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, etc., 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) via, for example, a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, and the like. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, electrically coupled, and the like.

[0037] 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. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as 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.

[0038] 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 to communicate with each other) using one or more sidelink channels. For example, UE 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 case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0039] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0040] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, which may be Figure 1 One for each base station and one for each UE in the base station 110. 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.

[0041] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the 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. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The 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, where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 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 up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0042] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 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 to 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.

[0043] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). 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 the UE 120 as well as other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and provide decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0044] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the base station 110 may perform one or more techniques associated with beam hopping within a single physical uplink control channel (PUCCH) resource, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 4 The process of 400 Figure 5 500, 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 4 The process of 400 Figure 5 The process 500 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.

[0045] In some aspects, UE 120 may include: means for receiving an activation command to activate multiple spatial relationships for a single PUCCH resource, means for communicating in the single PUCCH resource using the multiple spatial relationships, and the like. In some aspects, such means may include in conjunction with Figure 2 One or more components of UE 120 are depicted, such as 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.

[0046] In some aspects, base station 110 may include: means for determining multiple spatial relationships to be activated for a UE in a single PUCCH resource, means for transmitting an activation command to the UE to activate the multiple spatial relationships for the single PUCCH resource, and so on. In some aspects, such means may include combining Figure 2 One 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 the like.

[0047] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0048] Wireless communication devices (such as UE, BS, TRP, etc.) can use beams to communicate with each other. In some cases, beam indications (e.g., transmission configuration indication (TCI) status, quasi co-location (QCL) relationship, spatial relationship, etc.) can be signaled separately for different resources. For example, for uplink communication, the BS may indicate a set of spatial relationships to be used for different PUCCH resources (e.g., a set of eight spatial relationships). In addition, the BS may signal the activated spatial relationship for a specific PUCCH resource. For example, the BS may signal the first activated spatial relationship for a first PUCCH resource, the second activated spatial relationship for a second PUCCH resource, and so on.

[0049] In some cases, it may be beneficial for a UE to communicate using multiple beams to be received by different receivers (e.g., different antennas, panels, TRPs, BSs, etc.), thereby improving the communication performance of the UE. However, the UE may not be enabled to communicate using multiple beams in a single PUCCH resource. For example, the UE may use the same rate matching and resource mapping for a single PUCCH resource, which may impair the performance and reliability of communications using multiple beams to be received by different receivers (e.g., when the backhaul conditions between different receivers are not ideal). Some techniques and devices described herein enable a UE to communicate using multiple beams in a single PUCCH resource.

[0050] Figures 3A-3C is a diagram illustrating one or more examples 300 of beam hopping within a single PUCCH resource according to various aspects of the present disclosure. Figures 3A-3C As shown in , BS 110 and UE 120 may communicate with each other.

[0051] like Figure 3A In the example and as indicated by reference numeral 305, BS 110 may transmit and UE 120 may receive an activation command to activate a PUCCH resource for a single PUCCH resource (e.g., PUCCH resource 335, as shown in conjunction with Figure 3BThe BS 110 may determine multiple (e.g., two) spatial relations to be activated in a single PUCCH resource for the UE, and transmit an activation command to activate the multiple spatial relations. The activation command may be included in a media access control control element (MAC-CE) such as MAC-CE 310a or MAC-CE 310b. For example, the MAC-CE may include the activation command by identifying a spatial relationship identifier (e.g., PUCCH-SpatialRelationInfoIds (PUCCH-SpatialRelationInfoID)) of the multiple spatial relations to be activated.

[0052] The MAC-CE may also identify a single PUCCH resource for which multiple spatial relationships are to be activated, such as through a PUCCH resource identifier. The spatial relationship (e.g., spatial relationship information) may identify a serving cell, a reference signal (e.g., a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), etc.), a power control parameter (e.g., a PUCCH path loss reference signal (PL-RS), a power control offset value (referred to as a P0 parameter), a closed loop index, etc.), and the like.

[0053] In some aspects, the MAC-CE 310a may include a bitmap 315 for spatial relations. The bits (shown as S 0 -S 7 ) may be mapped to a spatial relationship configured for UE 120. For example, the first bit of bitmap 315 (eg, S 0 ) is mapped to the first spatial relationship configured for UE 120, and the second bit of bitmap 315 (eg, S 1 ) is mapped to a second spatial relationship configured for UE 120, and so on. In this example, multiple bits (e.g., two bits) of bitmap 315 may be set to indicate a spatial relationship to be activated (e.g., according to a mapping of bits to spatial relationships). The set bits may have a value of 1, and the unset bits may have a value of 0.

[0054] In some aspects, the MAC-CE 310b may include multiple fields for indicating the multiple spatial relationships. For example, the MAC-CE 310b may include a first field 320a for indicating a first spatial relationship to be activated and a second field 320b for indicating a second spatial relationship to be activated. In some aspects, the MAC-CE 310b may include additional fields for indicating additional spatial relationships to be activated. In some aspects, the MAC-CE 310b may include a flag 325 for indicating whether the second field 320b is present in the MAC-CE 310b. For example, the flag 325 may be set (e.g., set to a value of 1) to indicate that the second field 320b is present in the MAC-CE 310b.

[0055] The activated spatial relationship may be associated with a beam hop in the single PUCCH resource. For example, the first activated spatial relationship indicates a first beam hop in the single PUCCH resource (eg, beam hop 340a, as shown in conjunction with Figure 3B ), the second activated spatial relationship indicates a second beam hop in the single PUCCH resource (eg, beam hop 340b, as combined with Figure 3B ), and so on. Beam hopping may refer to a specific portion (e.g., a time domain portion) of the single PUCCH in which the UE 120 will communicate using a specific beam. Figure 3B 3 and indicated by reference numeral 330, the UE 120 may perform processing related to the activated spatial relationship. In some aspects, the UE 120 may determine resource allocation for a single PUCCH resource 335 for the beam hops indicated by the activated spatial relationship. For example, a first beam hop 340a indicated by a first activated spatial relationship may use a first portion of the symbols allocated to the single PUCCH resource 335, and a second beam hop 340b indicated by a second activated spatial relationship may use a second portion of the symbols allocated to the single PUCCH resource 335. As an example, N symbols may be allocated for the single PUCCH resource 335, and the first portion of the N symbols may be symbols, the second part of the N symbols may be In some aspects, the first portion of the codeword and the second portion of the codeword are separated by a gap of at least one codeword.

[0056] In some aspects, the UE 120 may determine that the first beam hop 340a will use the same spatial domain filter indicated by the first activated spatial relationship as used by the UE 120 for receiving a reference signal (e.g., SSB, CSI-RS, etc.) or transmitting a reference signal (e.g., SRS), and the second beam hop 340b will use the same spatial domain filter indicated by the second activated spatial relationship as used by the UE 120 for receiving a reference signal or transmitting a reference signal. In some aspects, the UE 120 may determine that the first beam hop 340a will use a first set of power control parameters (e.g., path loss reference signal (PL-RS), P0 parameter, closed loop index, etc.) indicated by the first activated spatial relationship, and the second beam hop 340b will use a second set of power control parameters indicated by the second activated spatial relationship.

[0057] In some aspects, the UE 120 may apply a time domain orthogonal cover code (OCC) on uplink control information (UCI) symbols (e.g., for sequence modulation) and / or demodulation reference signal (DMRS) symbols (e.g., for sequence generation) of a single PUCCH resource 335 per beam hop. In other words, the time domain OCC may be applied to symbols of a first beam hop 340a and a second beam hop 340b, respectively. In some aspects, when a single PUCCH resource 335 is allocated one or two UCI bits for some PUCCH formats (e.g., a single PUCCH resource 335 has PUCCH format 1), the UE 120 may apply the time domain OCC separately to each beam hop.

[0058] In some aspects, the UE 120 may determine a first number of DMRS symbols and positions of the DMRS symbols in a first beam hop 340a of a single PUCCH resource 335, and a second number of DMRS symbols and positions of the DMRS symbols in a second beam hop 340b of the single PUCCH resource 335. In some aspects, when the single PUCCH resource 335 is allocated more than two UCI bits for some PUCCH formats (e.g., the single PUCCH resource 335 has PUCCH format 3 or PUCCH format 4), the UE 120 may determine the DMRS number and position separately for each beam hop. In some aspects, the first DMRS number and position and the second DMRS number and position may be based at least in part on the length of the first beam hop 340a and the second beam hop 340b, respectively. For example, the UE 120 may be configured (e.g., configured by radio resource control (RRC)) with a mapping that identifies the DMRS number and position for different beam hop lengths.

[0059] In some aspects, the UE 120 may perform a first rate matching operation and / or a resource element (RE) mapping operation for a first beam hop 340a and a second rate matching operation and / or a RE mapping operation for a second beam hop 340b. In some aspects, when a single PUCCH resource 335 is allocated more than two UCI bits (e.g., a single PUCCH resource 335 has a PUCCH format 2, a PUCCH format 3, or a PUCCH format 4), the UE 120 may perform each rate matching operation and / or RE mapping operation separately. In some aspects, the UE 120 may determine information bits 345 to be processed by a rate matching operation, an RE matching operation, etc. The information bits 345 may be a payload (e.g., UCI) to be transmitted by the UE 120. The UE 120 may encode the information bits 345 (e.g., using polarity coding or coding for a small block length) and determine a rate matching output sequence based at least in part on the coded bits, as described below.

[0060] The UE 120 may determine a first rate matching output sequence length for the first beam hop 340a based at least in part on resources (e.g., REs) available for UCI in the first beam hop 340a (e.g., excluding resources to be used for DMRS), and determine a second rate matching output sequence length for the second beam hop 340b based at least in part on resources available for UCI in the second beam hop 340b. The UE 120 may perform a first rate matching operation 350a for the information bits 345 (e.g., decoded information bits 345) according to the determined first rate matching output sequence length, and perform a second rate matching operation 350b for the information bits 345 (e.g., decoded information bits 345) according to the determined second rate matching output sequence length.

[0061] In addition, the UE 120 may perform a first RE mapping operation for a first beam hop 340a using an output sequence of the first rate matching operation 350a (e.g., a modulated symbol corresponding to the output sequence of the first rate matching operation 350a is mapped to a resource of the first beam hop 340a), and perform a second RE mapping operation for a second beam hop 340b using an output sequence of the second rate matching operation 350b (e.g., a modulated symbol corresponding to the output sequence of the second rate matching operation 350b is mapped to a resource of the second beam hop 340b). In this way, the performance of the PUCCH may be improved, particularly when the first beam hop 340a and the second beam hop 340b are transmitted to different receivers.

[0062] In some aspects, UE 120 may determine a first PUCCH power value to be used for the first beam hop 340a, and a second PUCCH power value to be used for the second beam hop 340b. In some aspects, UE 120 may determine the PUCCH power value according to Equation 1 (as detailed in 3GPP Technical Specification 38.213, Section 7.2.1):

[0063]

[0064] UE 120 may determine a first PUCCH power value for a first beam hop 340a based at least in part on power control parameters (e.g., PL-RS, P0 parameters and / or closed-loop index) indicated by a first spatial relationship, and determine a second PUCCH power value for a second beam hop 340b based at least in part on power control parameters indicated by a second spatial relationship.

[0065] In some aspects, the corresponding closed-loop indexes indicated by the first spatial relationship and the second spatial relationship may be different. In this case, to determine the first PUCCH power value, the UE 120 may determine a first transmit power control (TPC) accumulation function value (i.e., g ) based at least in part on the first closed-loop index indicated by the first spatial relationship. b，f，c To determine the second PUCCH power value, UE 120 may determine a second TPC accumulation function value based at least in part on a second closed-loop index indicated by the second spatial relationship.

[0066] In addition, downlink control information (DCI) that schedules transmission of physical downlink shared channel (PDSCH) communications and UCI (e.g., acknowledgment feedback for PDSCH communications) in a single PUCCH resource 335 may indicate a TPC command (e.g., a value from 0 to 3). The TPC command may be mapped to a specific power adjustment to be used to determine the TPC accumulation function value. Accordingly, the UE 120 may apply the TPC command to the first closed-loop index (when determining the first TPC accumulation function value), the second closed-loop index (when determining the second TPC accumulation function value), or both the first and second closed-loop indexes (when determining the first and second TPC accumulation function values). In some aspects, the DCI may indicate corresponding TPC commands for the first closed-loop index and the second closed-loop index, and the UE 120 may determine the first and second TPC accumulation function values ​​based at least in part on the corresponding TPC commands. For example, multiple TPC commands may be indicated in respective TPC fields of the DCI, or a single TPC field of the DCI may indicate multiple TPC commands.

[0067] In some aspects, such as when the UE 120 performs separate rate matching operations and RE mapping operations for the first beam hop 340a and the second beam hop 340b (e.g., when the single PUCCH resource 335 has PUCCH format 2, PUCCH format 3, or PUCCH format 4), the number of mapped REs and / or the number of symbols carrying UCI may be different for the first beam hop 340a and the second beam hop 340b. This may affect Δ TF，b，f，c (i) Parameters. In this case, to determine the first PUCCH power value, the UE 120 may determine a first number of REs and / or a first number of symbols (e.g., for UCI) for the first beam hop 340a. To determine the second PUCCH power value, the UE 120 may determine a second number of REs and / or a second number of symbols for the second beam hop 340b.

[0068] As in Figure 3C 355, the UE 120 may communicate in a single PUCCH resource 335 using multiple spatial relationships. For example, the UE 120 may transmit and the BS 110 may receive PUCCH communications (e.g., UCI, such as hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback, channel state information, etc.) in a first beam hop 340a and a second beam hop 340b. In some aspects, the UE 120 may transmit PUCCH communications using a first beam (as indicated by a first activated spatial relationship) in the first beam hop 340a and a second beam (as indicated by a second activated spatial relationship) in the second beam hop 340b. In some aspects, the PUCCH communications in the first beam hop 340a may be received by a first receiver (e.g., a first antenna, a panel, a TRP, a BS, etc.), and the PUCCH communications in the second beam hop 340b may be received by a second receiver (e.g., a second antenna, a panel, a TRP, a BS, etc.).

[0069] In some aspects, the UE 120 may begin communicating using beam hopping upon receiving a MAC-CE (e.g., MAC-CE 310a or MAC-CE 310b) including an activation command for multiple spatial relationships. For example, the UE 120 may apply the activation command after a time window (e.g., 3 milliseconds) after the UE 120 transmits an acknowledgement feedback (e.g., HARQ-ACK feedback) for the PDSCH carrying the MAC-CE. Additionally or alternatively, the UE 120 may begin communicating using beam hopping upon receiving a configuration (e.g., RRC configuration) for multiple beam hopping for a single PUCCH resource 335 (e.g., RRC parameter intraSlotBeamHopping is enabled).

[0070] In some aspects, the UE 120 may communicate using beam hopping and frequency hopping (e.g., when the RRC parameter intraSlotFrequencyHopping is enabled for a single PUCCH resource 335). For example, the first beam hop 340a may use the first frequency hop and the second frequency hop, and the second beam hop 340b may use the first frequency hop and the second frequency hop. In this case, the UE 120 may apply time domain OCC on UCI symbols (e.g., for sequence modulation) and / or DMRS symbols (e.g., for sequence generation) of the single PUCCH resource 335 per beam hop and per frequency hop. In other words, the time domain OCC may be applied to symbols of the first beam hop 340a using the first frequency hop, the first beam hop 340a using the second frequency hop, the second beam hop 340b using the first frequency hop, and the second beam hop 340b using the second frequency hop, respectively.

[0071] As shown by reference numerals 360 and 365, the first portion of the symbols of a single PUCCH resource 335 (e.g., for the first beam hop 340a) is divided into multiple segments, and the second portion of the symbols of the single PUCCH resource 335 (e.g., for the second beam hop 340b) is divided into multiple segments. For example, a single PUCCH resource 335 (N symbols allocated, as described above) is divided into four segments. In this case, the segments may have or In some aspects, when a single PUCCH resource 335 is configured with at least eight symbols (e.g., the single PUCCH resource 335 has PUCCH format 1, PUCCH format 3, or PUCCH format 4), the single PUCCH resource 335 is divided into segments.

[0072] As shown by reference numeral 360, the UE 120 may communicate using respective beam hops within the plurality of frequency hops. For example, in a first frequency hop 370, the UE 120 may employ beam hopping using the first beam hop 340a and the second beam hop 340b. Continuing with the previous example, in a second frequency hop 375, the UE 120 may also employ beam hopping using the first beam hop 340a and the second beam hop 340b. Thus, as shown, the symbols for the first frequency hop 370 may be consecutive symbols of a single PUCCH resource 335, and the symbols for the second frequency hop 375 may be consecutive symbols of a single PUCCH resource 335. In some aspects, the UE 120 may receive a configuration (e.g., an RRC configuration) (e.g., from the BS 110) that configures the UE 120 to communicate using respective beam hops within the plurality of frequency hops.

[0073] As shown by reference numeral 365, the UE 120 may communicate using respective frequency hops within the plurality of beam hops. For example, in the first beam hop 340a, the UE 120 may employ frequency hopping using the first frequency hop 370 and the second frequency hop 375. Continuing with the previous example, in the second beam hop 340b, the UE 120 may also employ frequency hopping using the first frequency hop 370 and the second frequency hop 375. Thus, as shown, the symbols for the first beam hop 340a may be consecutive symbols of a single PUCCH resource 335, and the symbols for the second beam hop 340b may be consecutive symbols of a single PUCCH resource 335. In some aspects, the UE 120 may receive a configuration (e.g., an RRC configuration) (e.g., from the BS 110) that configures the UE 120 to communicate using respective frequency hops within the plurality of beam hops.

[0074] In this manner, a UE 120 may communicate according to multiple spatial relationships within a single PUCCH resource 335. This may improve throughput, reliability, performance, etc. of communications for the UE 120.

[0075] As indicated above, Figures 3A-3C is provided as one or more examples. Other examples may differ from those regarding Figures 3A-3C Examples described.

[0077] like Figure 4 As shown in , in some aspects, process 400 may include receiving an activation command to activate multiple spatial relationships for a single PUCCH resource (block 410). For example, a UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive an activation command to activate multiple spatial relationships for a single PUCCH resource, as described above.

[0104] although Figure 4An example block diagram of process 400 is shown, but in some aspects, process 400 may include Figure 4 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the process 400. Additionally or alternatively, two or more blocks of the process 400 may be executed in parallel.

[0105] Figure 5 is a diagram illustrating an example process 500, performed, for example, by a BS, in accordance with various aspects of the present disclosure.
