Description

Technical Field

[0001] In summary, various aspects of this disclosure relate to wireless communication and to techniques and apparatus for repetitive beam hopping in physical uplink control channel resources. Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable 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 / Improved LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0003] Wireless communication networks may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an 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 Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0004] The above multiple access technologies have been adopted in various telecommunications 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) (also known as 5G) is an enhancement set of the LTE mobile standard released by the 3rd Generation Partnership Project (3GPP). NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), thereby better supporting mobile broadband internet access, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. However, with the continued growth in demand for mobile broadband access, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunications standards that employ these technologies. Summary of the Invention

[0009] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication.

[0021] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or a method may be implemented using any number of the aspects set forth herein. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods implemented using structures, functions, or structures and functions other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0022] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in detail below and illustrated in the accompanying drawings, through various frames, 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 an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0023] It should be noted that although this document may use terms commonly associated with 3G and / or 4G wireless technologies to describe aspects, aspects of this disclosure can be applied to communication systems based on other generations (e.g., 5G and later, including NR technologies).

[0024] Figure 1This diagram illustrates a wireless network 100 in which various aspects of this disclosure may be implemented. The wireless network 100 may be an LTE network or some other wireless network (e.g., a 5G or NR network). The wireless network 100 may include multiple 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 user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, Transmit / Receive Point (TRP), etc. Each BS can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0025] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed User Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the examples shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0026] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, 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 (e.g., direct physical connection, virtual network, and / or similar interfaces using any suitable transport network).

[0027] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit the data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station can also be referred to as a relay BS, relay base station, repeater, etc.

[0028] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0029] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0030] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, user unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet device, camera, gaming device, netbook, smartbook, ultrabook, medical device or apparatus, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music or video device, or satellite radio unit, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0031] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, instruments, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing housing the components of UE 120, such as processor components, memory components, etc. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, etc.

[0032] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific Radio Access Technology (RAT) and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5GRAT networks can be deployed.

[0033] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication with each other). 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, mesh networks, etc.). In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described herein as being performed by base station 110.

[0034] As pointed out above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0035] Figure 2 Base station 110 and UE 120 are shown (they can be...) Figure 1 The block diagram of design 200 (a base station 110 and a UE 120) is shown. Base station 110 may be equipped with T antennas 234a to 234t, and UE 120 may be equipped with R antennas 252a to 252r, wherein generally, T≥1 and R≥1.

[0036] At base station 110, transmitting processor 220 can 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 channel quality indicators (CQI) received from each UE, process (e.g., code and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can (e.g., for OFDM, etc.) process its corresponding output symbol stream to obtain an output sample stream. Each modulator 232 can 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 can be transmitted via T antennas 234a to 234t respectively. According to the aspects described in more detail below, position coding can be used to generate synchronization signals to transmit additional information.

[0037] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor can determine the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), Channel Quality Indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in the housing.

[0038] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-encoded (if applicable) by the TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to base station 110. At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiving processor 238 to obtain decoded data and control information transmitted by UE 120. The receiver processor 238 can provide decoded data to the data sink 239 and decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicates 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.

[0039] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2Any other components may perform one or more techniques associated with repeated beam hopping in the Physical Uplink Control Channel (PUCCH) resources, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct, for example Figure 8 The process 800 Figure 9 The operation of process 900 and / or other processes as described herein. Memory 242 and 282 may store data and program code 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, one or more instructions may be executed or direct, for example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, translation, interpretation, etc.). Figure 8 The process 800 Figure 9 The operation of process 900 and / or other processes as described herein. In some aspects, the execution instructions may include run instructions, conversion instructions, compilation instructions, interpretation instructions, etc. Scheduler 246 can schedule the UE to perform data transmission on the downlink and / or uplink.

[0040] In some aspects, UE 120 may include: a unit for receiving an activation command for activating multiple spatial relationships for PUCCH resources, the PUCCH resources being used for transmitting repetitions of communication in multiple time slots; a unit for using multiple spatial relationships to transmit repetitions in the PUCCH resources in multiple time slots; and so on. In some aspects, such a unit may include a combination of Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0041] In some aspects, base station 110 may include: a unit for determining for a UE multiple spatial relationships to be activated for PUCCH resources, which will be used by the UE to transmit communications repeatedly in multiple time slots; a unit for sending an activation command to the UE for activating the multiple spatial relationships for PUCCH resources; and so on. In some aspects, such a unit may include a combination of Figure 2One or more components of the described base station 110, 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, etc.

[0042] As pointed out above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0043] Wireless communication devices (such as UEs, BSs, TRPs, etc.) can communicate with each other using beams. In some cases, beam indications (e.g., Transmission Configuration Indication (TCI) status, Quasi-Co-location (QCL) relationships, spatial relationships, etc.) can be signaled individually for different resources. For example, for uplink communication, a BS can indicate a set of spatial relationships to be used for different PUCCH resources (e.g., a set of eight spatial relationships). Furthermore, a BS can signal active spatial relationships for specific PUCCH resources. For example, a BS can signal a first active spatial relationship for a first PUCCH resource, a second active spatial relationship for a second PUCCH resource, etc.

[0044] In some cases, it may be beneficial for a UE to communicate using multiple beams that will be received by different receivers (e.g., different antennas, panels, TRPs, BSs, etc.), thereby improving the UE's communication performance. However, the UE may not be able to communicate using multiple beams that will be transmitted in multiple time slots within the PUCCH resource. Therefore, the diversity and / or reliability of communication may be compromised. Some techniques and apparatuses described herein enable a UE to communicate using multiple beams that will be transmitted in multiple time slots within the PUCCH resource.

[0045] Figure 3A and 3B This is a diagram illustrating one or more examples 300 of repeated beam hopping in a PUCCH resource according to various aspects of this disclosure. Figure 3A and 3B As shown, BS 110 and UE 120 can communicate with each other.

[0046] As in Figure 3A As shown by reference numeral 305 in the accompanying drawings, BS 110 can transmit and UE 120 can receive for activating PUCCH resources (e.g., as in combination). Figure 4-7The described PUCCH resource 415 is used for multiple (e.g., two) spatial relationships to be activated, which will be used for repeating PUCCH communications in multiple time slots (e.g., the PUCCH resource can be configured with more than one number of repeats (using the PUCCH format nrofSlots parameter). That is, the BS 110 can determine for the UE multiple spatial relationships to be activated for the PUCCH resource and send activation commands for activating the multiple spatial relationships. The activation commands can be included in a Media Access Control (MAC-CE) element (such as MAC-CE 310a or MAC-CE 310b). For example, the MAC-CE can include the activation commands by identifying the multiple spatial relationships to be activated by a spatial relationship identifier (e.g., PUCCH-SpatialRelationInfoId).

[0047] MAC-CE can also identify PUCCH resources for which multiple spatial relationships will be activated (e.g., via PUCCH resource identifiers). Spatial relationships (e.g., spatial relationship information) can identify serving cells, reference signals (e.g., synchronization signal block (SSB), channel state information reference signal (CSI-RS), sounding reference signal (SRS), etc.), power control parameters (e.g., PUCCH path loss reference signal (PL-RS), power control offset value (referred to as P0 parameter), closed-loop index, etc.).

[0048] In some aspects, MAC-CE 310a may include a bitmap 315 for spatial relationships. Bits of bitmap 315 (shown as S0-S7) may be mapped to spatial relationships configured for UE 120. For example, a first bit of bitmap 315 (e.g., S0) may be mapped to a first spatial relationship configured for UE 120, a second bit of bitmap 315 (e.g., S1) may be mapped to a second spatial relationship configured for UE 120, and so on. In this example, multiple bits of bitmap 315 (e.g., two bits) may be set to indicate the spatial relationship to be activated (e.g., according to the bit-to-spatial-relationship mapping). Set bits may have a value of one, and unset bits may have a value of zero.

[0049] In some aspects, MAC-CE 310b may include multiple fields for indicating multiple spatial relationships. For example, 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, MAC-CE 310b may include additional fields for indicating additional spatial relationships to be activated. In some aspects, MAC-CE 310b may include a flag 325 for indicating the presence of the second field 320b in MAC-CE 310b. For example, flag 325 may be set (e.g., set to a value of one) to indicate the presence of the second field 320b in MAC-CE 310b.

[0050] Activated spatial relationships can be associated with corresponding sets of repetitions to be transmitted in the PUCCH resource. For example, a first activated spatial relationship can be associated with a first repetition set (to be transmitted in a first time slot set), and a second activated spatial relationship can be associated with a second repetition set (to be transmitted in a second time slot set). In other words, the first activated spatial relationship can indicate the first beam to be used for the first repetition set (e.g., as combined with...). Figure 4-7 The described beam 1), and the second activation spatial relationship can indicate the second beam to be used for the second repeating set (e.g., as in combination). Figure 4-7 The described beam 2).

[0051] As in Figure 3B As shown by reference numeral 330 in the accompanying drawings, UE 120 can perform processing in association with an activation spatial relationship. In some aspects, UE 120 can determine that a first repetition set will use the same spatial filter (indicated by the first activation spatial relationship) used by UE 120 for receiving a reference signal (e.g., SSB, CSI-RS, etc.) or transmitting a reference signal (e.g., SRS), and a second repetition set will use the same spatial filter (indicated by the second activation spatial relationship) used by UE 120 for receiving or transmitting a reference signal. In some aspects, UE 120 can determine that a first repetition set 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 activation spatial relationship, and a second repetition set will use a second set of power control parameters indicated by the second activation spatial relationship.

[0052] In some aspects, UE 120 can determine a first PUCCH power value to be used for a first repeat set and a second PUCCH power value to be used for a second repeat set. In some aspects, UE 120 can determine the PUCCH power value according to Equation 1 (as detailed in Section 7.2.1 of 3GPP Technical Specification 38.213):

[0053]

[0054] UE 120 may determine a first PUCCH power value for a first repeat set 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 repeat set based at least in part on power control parameters indicated by a second spatial relationship.

[0055] In some respects, the corresponding closed-loop indices indicated by the first spatial relationship and the second spatial relationship may differ. In this case, to determine the first PUCCH power value, UE 120 may determine the first transmit power control (TPC) accumulation function value (i.e., g) at least in part based on the first closed-loop index indicated by the first spatial relationship. b,f,c (i,l)). To determine the second PUCCH power value, UE 120 may determine the second TPC accumulation function value at least in part based on the second closed-loop index indicated by the second spatial relationship.

[0056] Furthermore, the downlink control information (DCI) that schedules Physical Downlink Shared Channel (PDSCH) communication and UCI transmissions (e.g., acknowledgment feedback for PDSCH communication) in the PUCCH resource can indicate TPC commands (e.g., values ​​from 0 to 3). The TPC commands can be mapped to specific power adjustments used to determine the TPC accumulation function value. Therefore, UE 120 can apply TPC commands to a first closed-loop index (when determining a first TPC accumulation function value), a second closed-loop index (when determining a second TPC accumulation function value), or both (when determining the first and second TPC accumulation function values). In some aspects, the DCI can indicate corresponding TPC commands for the first and second closed-loop indices, and UE 120 can determine the first and second TPC accumulation function values ​​at least in part based on the corresponding TPC commands. For example, multiple TPC commands can be indicated in the corresponding TPC field of the DCI, or a single TPC field of the DCI can indicate multiple TPC commands.

[0057] As shown by reference numeral 335 in the attached figure, UE 120 can use multiple spatial relationships to transmit duplicates, and BS 110 can use multiple spatial relationships to receive duplicates. UE 120 can transmit duplicates at the opportune moment of the PUCCH resource in a time slot. For example, UE 120 can transmit a first duplicate in a first time slot at a first opportune moment of the PUCCH resource, a second duplicate in a second time slot at a second opportune moment of the PUCCH resource, and so on. Duplicates can have PUCCH communication (e.g., UCI, such as Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) feedback, channel state information, etc.).

[0058] In some aspects, UE 120 may use a first beam (as indicated by a first active spatial relationship) to transmit a first repeat set and a second beam (as indicated by a second active spatial relationship) to transmit a second repeat set. UE 120 may transmit the first repeat set in a first time slot set and the second repeat set in a second time slot set, as described below. Figure 4-7 Described. In some aspects, a first repeating set (transmitted using a first beam) can be received by a first receiver (e.g., a first antenna, panel, TRP, BS, etc.), and a second repeating set (transmitted using a second beam) can be received by a second receiver (e.g., a second antenna, panel, TRP, BS, etc.).

[0059] In some aspects, UE 120 may begin using multiple beams to transmit repetitions upon receiving a MAC-CE (e.g., MAC-CE 310a or MAC-CE 310b) that includes an activation command for multiple spatial relationships. For example, UE 120 may apply the activation command after a time window (e.g., 3 milliseconds) following UE 120 transmitting an acknowledgment feedback (e.g., HARQ-ACK feedback) for a PDSCH carrying the MAC-CE. Alternatively, UE 120 may begin using multiple beams to transmit repetitions (e.g., enabling the RRC parameter interSlotBeamHopping) upon receiving a configuration for multi-beam hopping of PUCCH resources in different time slots (e.g., Radio Resource Control (RRC) configuration).

[0060] As pointed out above, Figure 3A and 3B This is provided as one or more examples. Other examples may differ from those provided. Figure 3A and 3B The example described.

[0061] Figure 4 This is a diagram illustrating example 400 of repeated beam hopping in a PUCCH resource according to various aspects of this disclosure. Specifically, Figure 4Beam-hopping patterns 405 and 410 are shown for transmitting repeats in PUCCH resource 415 across multiple time slots. In example 400, four repeats are configured for PUCCH resource 415. However, in some aspects, different numbers of repeats can be configured for PUCCH resource 415, such as two or eight repeats.

[0062] As described above, the first repeat set can use the same spatial filter for receiving or transmitting reference signals, indicated by the first active spatial relationship, and the second repeat set can use the same spatial filter for receiving or transmitting reference signals, indicated by the second active spatial relationship. In other words, UE 120 can use a first beam (beam 1) to transmit the first repeat set and a second beam (beam 2) to transmit the second repeat set.

[0063] As shown in beam hopping mode 405, a first repeat set (using beam 1) and a second repeat set (using beam 2) can be cyclically mapped to PUCCH resources 415 in multiple time slots. In other words, the repeats in the first set alternate with the repeats in the second set. For example, as shown, UE 120 can use beam 1 in time slots 1 and 3 to transmit the repeats in the first set, and use beam 2 in time slots 2 and 4 to transmit the repeats in the second set. In other words, the repeats in the first set are even-index repeats (e.g., repeats 0 and 2), and the repeats in the second set are odd-index repeats (e.g., repeats 1 and 3). Alternatively, the repeats in the first set are odd-index repeats, and the repeats in the second set are even-index repeats.

[0064] As shown in beam hopping mode 410, repetitions in the first set (using beam 1) and repetitions in the second set (using beam 2) can be sequentially mapped to PUCCH resources 415 in multiple time slots. In other words, repetitions in the first set are in consecutive time slots, and repetitions in the second set are in consecutive time slots. For example, as shown, UE 120 can use beam 1 in time slots 1 and 2 to transmit the first set of repetitions, and use beam 2 in time slots 3 and 4 to transmit the repetitions in the second set. In other words, repetitions in the first set occur before repetitions in the second set. Alternatively, repetitions in the second set occur before repetitions in the first set.

[0065] In some aspects, the repetition patterns in the first set and the repetition patterns in the second set are indicated via RRC signaling. For example, BS 110 can send and UE 120 can receive an RRC configuration indicating the pattern that UE 120 will use. This pattern can be beam hopping mode 405 or beam hopping mode 410.

[0066] As pointed out above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0067] Figure 5A This is a diagram illustrating example 500 of repeated beam hopping in a PUCCH resource according to various aspects of this disclosure. Specifically, Figure 5A The diagram illustrates beam hopping patterns 405 and 410 for transmitting repeated beams in PUCCH resource 415 across multiple time slots, as combined with... Figure 4 The description states that in Example 500, four repeats are configured for PUCCH resource 415. However, in some aspects, different numbers of repeats can be configured for PUCCH resource 415, such as two or eight repeats.

[0068] In some aspects, UE 120 may not transmit a specific repeat scheduled to be transmitted in PUCCH resource 415 within a time slot. For example, UE 120 may not transmit the repeat in a time slot if the repeat has a potential conflict or overlap with another PUCCH communication that will be transmitted by UE 120 in the time slot. In this case, in some aspects, the pattern of repeats in the first set (using beam 1) and repeats in the second set (using beam 2) is defined without considering whether the repeat is transmitted.

[0069] As described above, according to beam hopping mode 405, repetitions from the first set and the second set are cyclically mapped to PUCCH resources 415 in multiple time slots. Therefore, repetitions in the first set (using beam 1) are mapped to time slots 1 and 3, and repetitions in the second set (using beam 2) are mapped to time slots 2 and 4, regardless of whether UE 120 transmits a specific repetition. For example, as shown, when time slot 2 is not used to transmit repetitions, the cyclic mapping mode of repetitions is unaffected.

[0070] As described above, according to beam hopping mode 410, repetitions from the first set and the second set are sequentially mapped to PUCCH resources 415 in multiple time slots. Therefore, repetitions in the first set (using beam 1) are mapped to time slots 1 and 2, and repetitions in the second set (using beam 2) are mapped to time slots 3 and 4, regardless of whether the UE 120 transmits a specific repetition. For example, as shown, when time slot 2 is not used to transmit repetitions, the sequential mapping of repetitions is unaffected.

[0071] As pointed out above, Figure 5A This is provided as an example. Other examples may differ from the one provided. Figure 5A The example described.

[0072] Figure 5B This is a diagram illustrating example 550 of repeated beam hopping in a PUCCH resource according to various aspects of this disclosure. Specifically, Figure 5B The diagram illustrates beam hopping patterns 405 and 410 for transmitting repeated beams in PUCCH resource 415 across multiple time slots, as combined with... Figure 4 The description states that in Example 500, four repeats are configured for PUCCH resource 415. However, in some aspects, different numbers of repeats can be configured for PUCCH resource 415, such as two or eight repeats.

[0073] In some respects, UE 120 may not transmit a specific repetition scheduled to be transmitted in a time slot in PUCCH resource 415, such as in combination with Figure 5A The description states that, in this context, the patterns of repetition in the first set (using beam 1) and repetition in the second set (using beam 2) are defined in some respects, taking into account whether or not the repetition is sent.

[0074] As described above, according to beam hopping mode 405, repetitions from the first set and the second set are cyclically mapped to PUCCH resources 415 in multiple time slots. For example, when time slot 2 is not used to transmit repetitions, repetitions from the first set (using beam 1) are mapped to time slots 1 and 4, and repetitions from the second set (using beam 2) that are to be transmitted are mapped to time slot 3. That is, repetitions from the first set and the second set are cyclically mapped to PUCCH resources 415 in the time slots in which the repetitions are actually transmitted.

[0075] As described above, according to beam hopping mode 410, repetitions from the first set and the second set are sequentially mapped to PUCCH resources 415 in multiple time slots. For example, when time slot 2 is not used to transmit repetitions, repetitions from the first set (using beam 1) are mapped to time slots 1 and 3, and repetitions from the second set (using beam 2) that are to be transmitted are mapped to time slot 4. That is, repetitions from the first set and the second set are sequentially mapped to PUCCH resources 415 in the time slots in which the repetitions are actually transmitted.

[0076] In some respects, whether the repeating pattern is defined with regard to whether a particular repeat is sent is indicated via RRC signaling. For example, BS 110 can send and UE 120 can receive an RRC configuration indicating whether the repeating pattern is defined with regard to whether a particular repeat is sent.

[0077] As pointed out above, Figure 5B This is provided as an example. Other examples may differ from the one provided. Figure 5B The example described.

[0078] Figure 6 This is a diagram illustrating example 600 of repeated beam hopping in a PUCCH resource according to various aspects of this disclosure. Specifically, Figure 6 A beam and frequency hopping pattern 605 and a beam and frequency hopping pattern 610 for transmitting repeats in PUCCH resource 415 across multiple time slots are illustrated. In example 600, four repeats are configured for PUCCH resource 415. However, in some aspects, different numbers of repeats can be configured for PUCCH resource 415, such as two or eight repeats.

[0079] like Figure 6 As shown, repetitions in the first set (using beam 1) can use a first frequency hop 615 and a second frequency hop 610, and repetitions in the second set (using beam 2) can use a first frequency hop 615 and a second frequency hop 620. Frequency hops can be inter-slot frequency hops. Furthermore, for example, when the RRC parameter interSlotFrequencyHopping is enabled for PUCCH resource 415, UE 120 can use beam hops and frequency hops for communication.

[0080] As shown in beam and frequency hopping pattern 605, repetitions in the first and second sets can be cyclically mapped to PUCCH resources 415 in multiple time slots, as combined with Figure 4 Described. Therefore, the first frequency transition 615 and the second frequency transition 620 for the repetition in the first set (using beam 1) are in discontinuous time slots, and the first frequency transition 615 and the second frequency transition 620 for the repetition in the second set (using beam 2) are in discontinuous time slots. For example, as shown, the first repetition in time slot 1 can use beam 1 and the first frequency transition 615, the second repetition in time slot 2 can use beam 2 and the first frequency transition 615, the third repetition in time slot 3 can use beam 1 and the second frequency transition 620, and the fourth repetition in time slot 4 can use beam 2 and the second frequency transition 620.

[0081] As shown in beam and frequency hopping pattern 610, repetitions in the first and second sets can be sequentially mapped to PUCCH resources 415 in multiple time slots, as combined with Figure 4Described. Therefore, the first frequency transition 615 and the second frequency transition 620 for the repetition in the first set (using beam 1) are in consecutive time slots, and the first frequency transition 615 and the second frequency transition 620 for the repetition in the second set (using beam 2) are in consecutive time slots. For example, as shown, the first repetition in time slot 1 can use beam 1 and the first frequency transition 615, the second repetition in time slot 2 can use beam 1 and the second frequency transition 620, the third repetition in time slot 3 can use beam 2 and the first frequency transition 615, and the fourth repetition in time slot 4 can use beam 2 and the second frequency transition 620.

[0082] In some aspects, a beam and frequency hopping mode is configured for UE 120 (e.g., via RRC signaling). For example, BS 110 can send and UE 120 can receive an RRC configuration indicating the mode that UE 120 will use. This mode can be beam and frequency hopping mode 605 or beam and frequency hopping mode 610.

[0083] As pointed out above, Figure 6 This is provided as an example. Other examples may differ from the one provided. Figure 6 The example described.

[0084] Figure 7 This is a diagram illustrating example 700 of repeated beam hopping in a PUCCH resource according to various aspects of this disclosure. Specifically, Figure 7 The diagram illustrates beam and frequency hopping patterns 705, 710, and 715 for transmitting repeats in PUCCH resource 415 across multiple time slots. In example 700, eight repeats are configured for PUCCH resource 415. However, in some aspects, different numbers of repeats, such as sixteen, can be configured for PUCCH resource 415.

[0085] like Figure 7 As shown, repetitions in the first set (using beam 1) can use a first frequency hop 615 and a second frequency hop 620, and repetitions in the second set (using beam 2) can also use a first frequency hop 615 and a second frequency hop 620. Frequency hops can be inter-slot frequency hops. Furthermore, for example, when the RRC parameter interSlotFrequencyHopping is enabled for PUCCH resource 415, UE 120 can use beam hops and frequency hops for communication.

[0086] The beam and frequency hopping mode 705 can be combined Figure 6The beam and frequency hopping pattern 605 is described. For example, time slots 1-4 can use a first repetition of beam and frequency hopping pattern 605, and time slots 5-8 can use a second repetition of beam and frequency hopping pattern 605. In other words, when eight repetitions are configured for PUCCH resource 415, the beam and frequency hopping pattern used for the cyclic mapping of four repetitions can be repeated.

[0087] The beam and frequency hopping mode 710 can be combined Figure 6 The beam and frequency hopping pattern 610 is described. For example, time slots 1-4 can use the first repetition of the beam and frequency hopping pattern 610, and time slots 5-8 can use the second repetition of the beam and frequency hopping pattern 610. In other words, when eight repetitions are configured for PUCCH resource 415, the beam and frequency hopping pattern used for the sequential mapping of four repetitions can be repeated.

[0088] As shown in beam and frequency hopping pattern 715, repetitions in the first and second sets can be sequentially mapped to PUCCH resources 415 in multiple time slots, as combined with Figure 4 Described. Therefore, the first frequency transition 615 and the second frequency transition 620 for repetitions in the first set (using beam 1) occur in consecutive time slots (e.g., the first frequency transition 615 and the second frequency transition 620 alternate in consecutive time slots), and the first frequency transition 615 and the second frequency transition 620 for repetitions in the second set (using beam 2) occur in consecutive time slots (e.g., the first frequency transition 615 and the second frequency transition 620 alternate in consecutive time slots). For example, as shown, repetitions in the first set (e.g., the first half of the repetition) can utilize the inter-slot frequency transition between the first frequency transition 615 and the second frequency transition 620 in time slots 1-4 using beam 1, and repetitions in the second set (e.g., the second half of the repetition) can utilize the inter-slot frequency transition between the first frequency transition 615 and the second frequency transition 620 in time slots 5-8 using beam 2.

[0089] In some aspects, a beam and frequency hopping mode is configured for UE 120 (e.g., via RRC signaling). For example, BS 110 can send and UE 120 can receive an RRC configuration indicating the mode that UE 120 will use. This mode can be beam and frequency hopping mode 705, beam and frequency hopping mode 710, or beam and frequency hopping mode 715.

[0090] As pointed out above, Figure 7 This is provided as an example. Other examples may differ from the one provided. Figure 7 The example described.

[0091] Figure 8This is a diagram illustrating, for example, an example process 800 performed by a UE according to various aspects of this disclosure. Example process 800 is an example in which a UE (e.g., UE 120, etc.) performs operations associated with repeated beam hopping for PUCCH resources.

[0092] like Figure 8 As shown, in some aspects, process 800 may include: receiving an activation command for activating multiple spatial relationships for PUCCH resources, which will be used for repetition of communication transmission in multiple time slots (block 810). 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 for activating multiple spatial relationships for PUCCH resources, which will be used for repetition of communication transmission in multiple time slots, as described above.

[0093] like Figure 8 As shown, in some aspects, process 800 may include: using multiple spatial relationships to transmit duplicates in the PUCCH resource in multiple time slots (block 820). For example, the UE (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.) may use multiple spatial relationships to transmit duplicates in the PUCCH resource in multiple time slots, as described above.

[0094] Process 800 may include additional aspects, such as any single aspect or any combination thereof described below and / or in conjunction with one or more other process descriptions elsewhere described herein.

[0095] In the first aspect, the activation command is received via MAC-CE.

[0096] In the second aspect, either alone or in combination with the first aspect, the MAC-CE includes a bitmap for spatial relationships, and multiple bits of the bitmap are set to indicate multiple spatial relationships that will be activated.

[0107] In the thirteenth aspect, either alone or in combination with one or more aspects from the first to the twelfth aspects, the patterns of repetition in the first set and repetition in the second set are defined with regard to whether a particular repetition is sent.

[0108] In the fourteenth aspect, whether the patterns of repetition in the first set and repetition in the second set are defined, alone or in combination with one or more of the first to thirteenth aspects, are indicated via RRC signaling.

[0109] In the fifteenth aspect, either alone or in combination with one or more aspects from the first to the fourteenth aspects, the first set reuses the first PUCCH power value, and the second set reuses the second PUCCH power value.

[0110] In the sixteenth aspect, either alone or in combination with one or more of the first to fifteenth aspects, the first PUCCH power value is at least partially based on at least one of the first PL-RS, the first offset value, or the first closed-loop index, and the second PUCCH power value is at least partially based on at least one of the second PL-RS, the second offset value, or the second closed-loop index.

[0117] Although Figure 8 An example box of process 800 is shown, but in some aspects, process 800 may include... Figure 8 The boxes depicted in the diagram are compared to additional boxes, fewer boxes, different boxes, or boxes arranged in a different manner. Alternatively, two or more boxes in process 800 may be executed in parallel.

[0118] Figure 9 This is a diagram illustrating, for example, an example process 900 performed by a BS according to various aspects of this disclosure. Example process 900 is an example in which a BS (e.g., BS 110, etc.) performs operations associated with repeated beam switching in PUCCH resources.

[0119] like Figure 9 As shown, in some aspects, process 900 may include: determining for the UE multiple spatial relationships to be activated for PUCCH resources, which the UE will use repeatedly to transmit communications in multiple time slots (block 910). For example, the BS (e.g., using controller / processor 240, etc.) may determine for the UE multiple spatial relationships to be activated for PUCCH resources, which the UE will use repeatedly to transmit communications in multiple time slots, as described above.

[0120] like Figure 9 As further shown, in some aspects, process 900 may include sending an activation command to the UE for activating multiple spatial relationships for PUCCH resources (block 920). For example, the BS (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.) may send an activation command to the UE for activating multiple spatial relationships for PUCCH resources as described above.

[0121] Process 900 may include additional aspects, such as any single aspect or any combination thereof described below and / or in conjunction with one or more other process descriptions elsewhere described herein.

[0122] In the first aspect, the activation command is sent via MAC-CE.

[0123] In the second aspect, either alone or in combination with the first aspect, the MAC-CE includes a bitmap for spatial relationships, and multiple bits of the bitmap are set to indicate multiple spatial relationships that will be activated.

[0124] In the third aspect, either alone or in combination with one or more of the first and second aspects, MAC-CE includes a first field indicating a first spatial relation to be activated and a second field indicating a second spatial relation to be activated.

[0125] In the fourth aspect, either alone or in combination with one or more of the first to third aspects, MAC-CE includes a flag set when the second field is included in MAC-CE.

[0126] In the fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the repeated first set will use a spatial filter for receiving or transmitting a reference signal indicated by a first spatial relationship among a plurality of spatial relationships, and the repeated second set will use a spatial filter for receiving or transmitting a reference signal indicated by a second spatial relationship among a plurality of spatial relationships.

[0127] In the sixth aspect, either alone or in combination with one or more of the first to fifth aspects, repetitions in the first set will use a first set of power control parameters indicated by a first spatial relationship, and repetitions in the second set will use a second set of power control parameters indicated by a second spatial relationship.

[0128] In the seventh aspect, either alone or in combination with one or more aspects from the first to the sixth aspects, the repetitions in the first set alternate with the repetitions in the second set.

[0129] In the eighth aspect, either alone or in combination with one or more aspects from the first to the seventh aspect, the repetition in the first set is an even-index repetition, and the repetition in the second set is an odd-index repetition.

[0130] In the ninth aspect, either alone or in combination with one or more aspects from the first to the eighth aspects, the repetition in the first set is continuous, and the repetition in the second set is continuous.

[0131] In the tenth aspect, either alone or in combination with one or more aspects from the first to the ninth aspect, the repetition in the first set will occur before the repetition in the second set.

[0132] In the eleventh aspect, either alone or in combination with one or more aspects from the first to the tenth aspects, the repetition patterns in the first set and the repetition patterns in the second set are indicated via RRC signaling.

[0133] In the twelfth aspect, either alone or in combination with one or more aspects from the first to the eleventh aspects, the patterns of repetition in the first set and the patterns of repetition in the second set are defined without regard to whether the UE sends a specific repetition.

[0134] In the thirteenth aspect, the patterns of repetition in the first set and repetition in the second set are defined, either alone or in combination with one or more of the first to twelfth aspects, taking into account whether the UE sends a specific repetition.

[0135] In the fourteenth aspect, whether the patterns of repetition in the first set and repetition in the second set are defined, alone or in combination with one or more of the first to thirteenth aspects, are indicated via RRC signaling.

[0136] In the fifteenth aspect, either alone or in combination with one or more aspects from the first to the fourteenth aspects, the first set reuses the first PUCCH power value, and the second set reuses the second PUCCH power value.
