[0002] This patent application claims priority to Chinese patent application No. PCT / CN2021 / 070409, filed on January 6, 2021, entitled “BEAM PARAMETER DETERMINATION FOR CHANNEL REPETITIONS,” which has been assigned to the assignee of this application. The disclosure of the prior application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0003] In summary, various aspects of this disclosure relate to wireless communication, as well as techniques and apparatus for determining beam parameters for channel repetition. Background Technology

[0004] 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).

[0005] A wireless network may include a number of base stations (BSs) capable of supporting communication for a number of user equipments (UEs). UEs may communicate with the BS via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, and 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.

[0006] 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. NR (which can also be called 5G) is an enhancement set of the LTE mobile standard released by 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) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation, thereby better supporting mobile broadband internet access. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0020] 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 specific structure or function given 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 the disclosure made herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or method may be implemented using any number of aspects set forth herein.

It should be understood that any aspect of the disclosure made herein may be embodied by one or more elements of the claims.

[0021] 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, by way of various frames, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements may 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.

[0022] It should be noted that although the aspects may be described herein using terms commonly associated with 5G or NR radio access technology (RAT), the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0023] Figure 1This is a schematic diagram illustrating an example of a wireless network 100 according to various aspects of this disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, node B, gNB, 5G node B (NB), access 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.

[0024] 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 allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographic area and allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and 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 called a macro BS. A BS used for picocells can be called a pico BS. A BS used for femtocells can be called a femto 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.

[0025] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may be movable depending on the location of the mobile BS. In some respects, any suitable transport network can be used to interconnect BSs with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0026] 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 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 BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, repeater, etc.

[0027] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) such as 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).

[0028] 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 via wireless or wired backhaul.

[0029] 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, subscriber 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 equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), 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.

[0030] 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, and / or location tags that 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 a cellular network) 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 and / or memory components. 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, and / or electrically coupled.

[0031] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific 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, frequency 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 5G RAT networks can be deployed.

[0032] 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, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.) and / or mesh networks. In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0033] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) (which can span from 410 MHz to 7.125 GHz), and / or can communicate using an operating band with a second frequency range (FR2) (which can span from 24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "below 6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that the terms "below 6 GHz" and the like (if used herein) can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave" and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., below 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[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 This is a schematic diagram illustrating an example of communication between a base station 110 and a UE 120 in a wireless network 100 according to various aspects of this disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically 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)) and control information (e.g., CQI requests, permission, and / or upper-layer signaling), 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) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or 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) process its respective 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.

[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) to obtain received symbols. 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. Receive 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 term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Reference Signal Received Power (RSRP) parameter, the Received Signal Strength Indicator (RSSI) parameter, the Reference Signal Received Quality (RSRQ) parameter, and / or the Channel Quality Indicator (CQI) parameter, as well as other examples. In some aspects, one or more components of the UE 120 may be included within the housing 284.

[0038] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in the core network. Network controller 130 may communicate with base station 110 via communication unit 294.

Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components in the process).

[0040] 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 reporting RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-coded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as referenced. Figures 4-7 Described.

[0041] 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 receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and transmission to network controller 130 via communication unit 244.

In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 7 The operation of process 700 and / or other processes as described herein. In some aspects, execution instructions may include run instructions, translation instructions, compilation instructions and / or interpretation instructions, and other examples.

[0043] In some aspects, a wireless communication device includes units for receiving at least one channel repetition among a plurality of channel repetitions, wherein the at least one channel repetition includes an indication associated with beam parameters; and / or units for performing wireless communication actions at least in part based on a determination associated with beam parameters, wherein the determination associated with beam parameters is at least in part based on the identification of a reference repetition timing among a plurality of repetition timings corresponding to the plurality of channel repetitions. In some aspects, units for the wireless communication device to perform the operations described herein may include, for example, one or more of the following: a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0048] 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.

[0049] Figure 3 This is a schematic diagram illustrating example 300 of wireless communication including channel duplication according to various aspects of this disclosure. Figure 3 As shown, wireless communication device 305 and wireless communication device 310 can communicate with each other. Wireless communication device 305 and wireless communication device 310 can communicate via a wireless network (e.g., in...). Figure 1 The wireless networks 100 shown communicate with each other. Wireless communication devices 305 and / or 310 may be, for example, UEs, base stations, relay stations and / or integrated and access backhaul nodes, and other examples.

[0050] As shown, wireless communication device 310 can repeat the transmission of Physical Downlink Control Channel (PDCCH) communication, which may be referred to as PDCCH repetition 315. As used herein, "repetition" means more than one transmission of communication, and refers to the initial transmission of the communication or any subsequent retransmission of the communication. Repetition can be used to increase the signal-to-noise ratio (SNR) to improve transmission reliability.

[0051] PDCCH repetition 315 can be repeated on a number of search spaces 320, 325. Each PDCCH repetition 315 can be associated with different core resource sets (CORESET) 330 and 335, respectively. CORESET 330 and 335 can be associated with different search spaces 320 and 325, the same search space 330 or 335, or different time slots. Each PDCCH repetition 315 can be associated with Physical Downlink Shared Channel (PDSCH) communication 340. For example, PDCCH repetition 315 may include downlink control information (DCI) that schedules and / or triggers PDSCH communication 340. In some aspects, PDSCH communication 340 can be a PDSCH repetition within a number of PDSCH repetitions. Similarly, as shown, wireless communication device 305 can repeat the transmission of Physical Uplink Control Channel (PUCCH) communication, which can be referred to as PUCCH repetition 345. PUCCH repetition 345 can be transmitted within a number of time slots 350 and 355. In some cases, such as when indicated by "ACK", PUCCH repeat 345 may carry an acknowledgment indicator associated with PDCCH repeat 315. In some aspects, any number of repeats of communication may be sent.

[0052] Wireless communication devices 305 and 310 may use beamforming to facilitate communication with each other. One of the wireless communication devices 305 and 310 may indicate a beam to be used for communication to the other device. A “beam” may refer to directional transmission, such as a wireless signal transmitted in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal.

[0053] Antenna elements and / or sub-elements can be used to generate a beam. For example, antenna elements can be individually selected or deselected for the transmission of a signal (or multiple signals) by controlling the amplitude of one or more respective amplifiers. Beamforming involves generating a beam using multiple signals on different antenna elements, wherein one or more, or all, of the multiple signals are phase-shifted relative to each other. The formed beam can carry physical or higher-level reference signals or information. As each of the multiple signals is radiated from its respective antenna element, the radiated signals interact, interfere (constructive and destructive interference), and amplify to form the resulting beam. The shape (such as amplitude, width, and / or the presence of sidelobes) and orientation (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts or phase offsets of the multiple signals relative to each other.

[0054] In 5G and other types of RATs, beamforming can be used for communication between the UE and the base station, such as for millimeter-wave communication. In such cases, the base station can provide the UE with a Transmission Configuration Information (TCI) state configuration, which indicates the beams that the UE can use, such as those for receiving PDSCH. The base station can indicate the active TCI state to the UE, which the UE can use to select the beam for receiving PDSCH.

[0055] Beam indication is an indication of a beam. Beam indication can be or includes TCI state information elements, beam identifiers (IDs), spatial relationship information, TCI state IDs, closed-loop indexes, panel IDs, TRP IDs, and / or SRS set IDs, and other examples. TCI state information elements (referred to herein as TCI states) can indicate information associated with a beam, such as a downlink beam. For example, TCI state information elements can indicate a TCI state identifier (e.g., tci-StateID), quasi-co-location (QCL) type (e.g., qcl-Type1, qcl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, qcl-TypeD, etc.), cell identifier (e.g., ServCellIndex), bandwidth portion identifier (bwp-Id), reference signal identifier (such as CSI-RS (e.g., NZP-CSI-RS-ResourceId, SSB-Index, etc.)), etc. Spatial relationship information can similarly indicate information associated with an uplink beam.

[0056] Beam indication can be a combined or separate downlink (DL) / uplink (UL) beam indication within a unified Transport Configuration Indicator (TCI) framework. In some cases, the network may support Layer 1 (L1) based beam indication using at least a UE-specific (unicast) DCI to indicate a combined or separate DL / UL beam indication from an active TCI state. In some cases, existing DCI formats 1_1 and / or 1_2 may be reused for beam indication. The network may include support mechanisms for UE confirmation of successful decoding of the beam indication. For example, acknowledgment / negation acknowledgment (ACK / NACK) of a PDSCH scheduled via a DCI carrying the beam indication may also be used as an ACK for the DCI.

[0057] Beam indication can be provided for carrier aggregation (CA) scenarios. Within a unified TCI framework, the network can support the updating and activation of a common TCI state identifier (ID) to provide common quasi-co-location (QCL) information and / or one or more common UL transmission space filters across a configured set of component carriers (CCs). This type of beam indication can be applied to in-band CA as well as joint DL / UL and individual DL / UL beam indication. A common TCI state ID can mean that a reference signal (RS) determined based on the TCI state indicated by the common TCI state ID is used to provide QCL Type-D indication and to determine the UL transmission space filters across the configured set of CCs.

[0058] In some cases, time offsets can be defined for applying a non-default beam. For example, the duration for applying a non-default beam can be specified as the `timeDurationforQCL` variable. The `timeDurationforQCL` variable can be the duration that enables the wireless communication device to prepare for receiving communication using a non-default beam. If the duration is unavailable, the wireless communication device can apply (e.g., prepare to use) the default beam. For example, the `timeDurationforQCL` variable can be defined such that if `tci-PresentInDCI` is set to "enabled" or `tci-PresentForDCI-Format1-2-r16` is configured for scheduling the PDSCH CORESET, and the time offset between the reception of the DL DCI and the corresponding PDSCH is equal to or greater than `timeDurationForQCL`, then after the wireless communication device receives the initial higher-layer configuration of the TCI state and before receiving the activation command, the wireless communication device can assume that the DM-RS port of the serving cell's PDSCH is quasi-co-located with the SS / PBCH block determined during the initial access process regarding "QCL-Type A" (and, where applicable, also regarding "QCL-Type D").

[0059] In some aspects, beam parameters may include beam switching timing, which can be specified as a beamSwitchTiming variable. The beamSwitchTiming variable can be specified as the duration for which the wireless communication device is prepared to receive a new beam for the channel state information reference signal (CSI-RS) resource. beamSwitchTiming can also be defined such that if the scheduling offset between the last symbol of the PDCCH carrying the trigger DCI and the first symbol of the aperiodic CSI-RS resource is equal to or greater than the threshold beamSwitchTiming reported by the wireless communication device (when the reported value is one of the values ​​{14, 28, 48}) and enableBeamSwitchTiming-r16 is not provided, or if the scheduling offset is equal to or greater than 48 (when the reported value of beamSwitchTiming-r16 is one of the values ​​{224, 336}) and enableBeamSwitchTiming-r16 is provided, then the wireless communication device can be expected to apply the QCL assumption in the indicated TCI state for the aperiodic CSI-RS resource under the CSI trigger state indicated by the CSI trigger field in the DCI.

[0060] In some aspects, beam parameters may include beam reset timing. For example, the UE may be configured via the parameter schedulingRequestID-BFR-SCell-r16 for PUCCH transmissions with Link Recovery Request (LRR). The UE may transmit a Medium Access Control (MACCE) element in the First Physical Uplink Shared Channel (PUSCH) that provides one or more indices for at least one or more corresponding SCells with radio link quality worse than a quality threshold, and one or more indices q for the corresponding secondary cell (SCell). new One or more indications of existence, and an index q provided by a higher layer (if any) for the corresponding SCell for periodic CSI-RS configuration or for the Synchronization Signal / Physical Broadcast Channel (SS / PBCH) block. new After 28 symbols from the last symbol received from a PDCCH in DCI format that has a PUSCH transmission with the same Hybrid Automatic Repeat Request (HARQ) procedure number as the transmission used for the first PUSCH and a New Data Indicator (NDI) field value with toggled switching, the UE can use the PDCCH with the corresponding index q. new(If applicable) The antenna port quasi-co-address parameters are the same as those associated with the PDCCH in all core resource sets (CORESET) on the SCell indicated by the MAC CE, and can be used with the q parameters used for periodic CSI-RS or SS / PBCH block reception. new The corresponding spatial filter is the same spatial filter and the power is determined based on the specification to transmit PUCCH on PUCCH-SCell. If the UE is provided with the parameter PUCCH-SpatialRelationInfo for PUCCH, the PUCCH with LRR is not transmitted or is transmitted on the primary cell (PCell) or primary-secondary cell group cell (PSCell), and the PUCCH-SCell is included in the SCell indicated by MAC-CE, wherein the subcarrier spacing (SCS) configuration for 28 symbols is the smallest of the SCS configuration for the active DL bandwidth portion (BWP) for PDCCH reception and the SCS configuration for the active DL BWP of at least one SCell.

[0061] For PCell or PSCell, after 28 symbols from the last symbol of the first PDCCH received in the search space set provided by the parameter recoverySearchSpaceId (for downlink control information (DCI) format scrambled by the Cell Radio Network Temporary Identifier (C-RNTI) or Modulation and Coding Scheme (MCS)-C-RNTI), and until the UE receives an activation command for the parameter PUCCH-SpatialRelationInfo or is provided with the parameter PUCCH-SpatialRelationInfo for PUCCH resources, the UE may transmit PUCCH on the same cell as the PRACH transmission using the same spatial filter as the spatial filter used for the last Physical Random Access Channel (PRACH) transmission or with a power determined based on the specification. For PCell or PSCell, after 28 symbols from the last symbol received by the first PDCCH in the search space set provided by the parameter recoverySearchSpaceId (where the UE detects a DCI format with CRC scrambled by C-RNTI or MCS-C-RNTI), the UE can assume an index q following the PDCCH monitoring in the CORESET with index 0. new The associated antenna port quasi-co-address parameters are the same.

[0062] In some cases, wireless communication standards may indicate a formula for determining the transmit power control (TPC) timing for PUSCH. A portion of this formula may include K on the active UL BWP b of the UE on carrier f of the serving cell C for PUSCH power control adjustment state l before PUSCH transmission timing i-i0. PUSCH (i-i0)-1 symbols and K before the PUSCH transmission timing i PUSCH (i) The received symbols have a base C(D) i The set of TPC command values ​​D i The sum of the TPC command values ​​in the data, where i-i0 is the value before K in the PUSCH transmission time i-i0. PUSCH (i-i0) symbols are earlier than K symbols that occurred before PUSCH transmission time i. PUSCH The smallest integer of (i) symbols. If the PUSCH transmission is scheduled via DCI format, then K PUSCH (i) is the number of active UL BWP b symbols for carrier f serving cell C after the last symbol received by the corresponding PDCCH and before the first symbol transmitted by the PUSCH.

[0063] In some cases, wireless communication standards may indicate a formula for determining the TPC timing for PUCCH. A portion of this formula may include K on the active ULBWP b of the serving cell C for PUCCH power control adjustment state, prior to PUCCH transmission timing i-i0. PUSCH (i-i0)-1 symbols and K before the PUCCH transmission timing i PUSCH (i) The base C(C) received between symbols i The set of TPC command values ​​C i The sum of TPC command values ​​in, where i 0> 0 refers to K before the PUCCH transmission time i-i0. PUSCH (i-i0) symbols are earlier than K symbols that occur before PUCCH transmission time i. PUSCH The smallest integer of (i) symbols. If the PUCCH transmission is in response to the UE detecting DCI format 1_0 or DCI format 1_1, then K PUSCH (i) is the number of active UL BWP b symbols for carrier f serving cell C after the last symbol received by the corresponding PDCCH and before the first symbol transmitted by the PUCCH.

[0064] In some cases, wireless communication standards may indicate a formula for determining the TPC timing used for Sounding Reference Signals (SRS). This formula may indicate the timing for a UE not configured for PUSCH transmission on an active UL BWP b on carrier f of serving cell C, either if the parameter srs-PowerControlAdjustmentStates indicates a separate power control adjustment state between SRS transmission and PUSCH transmission, or if the parameter tpc-Accumulation is not provided. A portion of the formula may include K of the UE's time before SRS transmission timing i-i0 on an active UL BWP b on carrier f of serving cell C for SRS power control adjustment states. SRS (i-i0)-1 symbols and K symbols prior to SRS transmission timing i SRS (i) The base C(S) received between symbols i The set of TPC command values ​​S i The sum of TPC command values ​​in, where i 0> 0 refers to K before the SRS transmission timing i-i0. SRS (i-i0) symbols are earlier than K symbols prior to SRS transmission timing i. SRS The smallest integer of (i) symbols. If the SRS transmission is periodic, then K SRS (i) is the number of active UL BWP b symbols for carrier f serving cell C after the last symbol of the corresponding PDCCH that triggers the SRS transmission and before the first symbol of the SRS transmission.

[0065] In some cases, non-periodic CSI reports may occupy the CSI processing unit (CPU) from the first symbol after the PDCCH that triggers the CSI report until the last symbol between the Z3 symbols following the first symbol after the PDCCH that triggers the CSI report and the last symbol between the Z′3 symbols following the last symbol of the most recent CSI-RS / SSB resource in each CSI-RS / SSB resource used for channel measurements for L1-RSRP calculation.

[0066] The various features and support described above can facilitate accurate and efficient beamforming, beam failure recovery, transmit power control, and / or CPU utilization. However, the timing of the described events depends on the reception of beam-related indications (e.g., beam indication, acknowledgments associated with the beam indication, scheduling DCI). In cases of channel duplication (where the indication can be sent more than once), there may be ambiguity regarding which transmission to use as the reference for timing the event. Determining timing based on incorrect transmissions can lead to inappropriate beamforming, which can negatively impact network performance.

[0067] The techniques and apparatus described herein prepare for determining the timing of events (such as the application time for beam indication and the time offset for applying the default beam in a channel repetition implementation) by defining event timing based on a reference repetition timing. In some aspects, a wireless communication device can receive at least one channel repetition from another wireless communication device. The wireless communication device can identify the reference repetition timing and perform beam parameter-related determinations based at least in part on the reference repetition timing. In this way, aspects can facilitate signaling supporting beamforming in a channel repetition implementation. As a result, such aspects have a positive impact on network performance.

[0068] As pointed out above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0069] Figure 4 This is a schematic diagram illustrating an example 400 associated with beam parameter determination for channel repetition according to various aspects of this disclosure. As shown, wireless communication device 405 and wireless communication device 410 can communicate with each other. Wireless communication device 405 and / or wireless communication device 410 can be, similar to, or included in Figure 1 The base station 110 and / or UE 120 shown are illustrated.

[0070] As indicated by reference numeral 415, wireless communication device 410 can transmit and wireless communication device 405 can receive at least one of a plurality of channel repetitions. At least one channel repetition may include control channel repetition and / or shared channel repetition. For example, at least one channel repetition may include physical downlink control channel (PDCCH) repetition, physical uplink control channel (PUCCH) repetition, and / or physical uplink shared channel (PUSCH) repetition.

[0071] At least one channel repetition may include an indication associated with beam parameters. In some aspects, the indication associated with beam parameters may include a beam indication. In some aspects, the indication associated with beam parameters may include an acknowledgment corresponding to the beam indication.

[0072] As indicated by reference numeral 420, a wireless communication device can identify a reference repetition timing among multiple repetition timings corresponding to multiple channel repetitions, and as indicated by reference numeral 425, can perform determinations associated with beam parameters based at least in part on the identification of the reference repetition timing. A repetition timing is a time allocation associated with a nominal repetition or an actual repetition.

[0073] For example, in a unified TCI framework where beam indication is indicated as a unified TCI state, the application time of the beam indication upon receipt can be a first time slot separated from the reference PDCCH repetition in multiple PDCCH repetition timings by a time offset. The time offset can be, for example, X milliseconds (ms), X time slots, or Y symbols after the reference PDCCH repetition timing. In some aspects, the unified TCI state can be a joint TCI state that provides beam indication to at least one downlink channel and at least one uplink channel. In some aspects, the unified TCI state can be a separate DL common TCI state that provides beam indication to at least two downlink channels. In some aspects, the unified TCI state can be a separate UL common TCI state that provides beam indication to at least two uplink channels. The unified TCI state as described herein can include at least one reference signal (e.g., a source reference signal) to provide a reference (e.g., a UE assumption) for determining QCL relationships, spatial filters, etc., to a target downlink or uplink channel.

[0074] In some aspects, for example, beam parameters may include the application time associated with a beam identified by a beam indicator. Wireless communication device 405 may identify a reference repetition timing and determine the application time, at least in part, based on applying a time offset to a start time. The start time may correspond to a reference repetition timing.

[0075] Reference repetition timings may include PDCCH repetition timings associated with CORESET pool index values ​​that satisfy indexing criteria, wherein at least two of the multiple repetition timings are associated with at least two CORESETs having different CORESET pool index values. For example, reference repetition timings may include PDCCH repetition timings that have the highest CORESET pool index, the lowest CORESET pool index, and / or a CORESET pool index that satisfies a CORESET pool index threshold in the CORESET pool indexes corresponding to the repetition timing.

[0076] In some aspects, a reference repetition timing may include a PDCCH repetition timing associated with a CORESET ID that satisfies the CORESET ID condition. For example, a reference repetition timing may include a PDCCH having the highest CORESET ID, the lowest CORESET ID, and / or a CORESET ID that satisfies the CORESET ID threshold among the CORESET IDs corresponding to the repetition timing. In some aspects, a reference repetition timing may include a PDCCH repetition timing associated with a search space ID that satisfies the search space ID condition. For example, a reference repetition timing may include a PDCCH having the highest search space ID, the lowest search space ID, and / or a search space ID that satisfies the CORESET ID threshold among the search space IDs corresponding to the repetition timing.

[0077] The reference repetition timing may include a PDCCH repetition timing associated with a PDCCH monitoring timing that meets the monitoring timing conditions. For example, the reference repetition timing may include a PDCCH that has the earliest PDCCH monitoring timing, the most recent PDCCH monitoring timing, and / or a PDCCH monitoring timing that meets the PDCCH monitoring timing threshold among the PDCCH monitoring timings corresponding to the repetition timing.

[0078] Reference repetition timing may include a PDCCH repetition timing associated with a PDCCH reference symbol that satisfies the reference symbol condition. For example, a reference repetition timing may include a PDCCH that has the earliest PDCCH reference symbol among the PDCCH reference symbols (e.g., the start or end symbol of the corresponding timing), the most recent PDCCH reference symbol, and / or a PDCCH reference symbol that satisfies the PDCCH reference symbol threshold.

[0079] Reference repetition timings can include PDCCH repetition timings associated with resource indexes that meet resource index criteria. For example, reference repetition timings can include PDCCH repetition timings associated with the highest resource index among the resource indexes associated with repetition timings, PDCCH repetition timings associated with the lowest resource index, and / or PDCCH repetition timings associated with resource index thresholds. A resource index can be an index of a resource block or resource element associated with a PDCCH repetition timing.

[0080] Reference repetition timings can include PDCCH repetition timings associated with PDCCH candidate indexes that meet the candidate index criteria. For example, reference repetition timings can include PDCCH repetition timings associated with the highest PDCCH candidate index among the PDCCH candidate indexes associated with repetition timings, PDCCH repetition timings associated with the lowest PDCCH candidate index, and / or PDCCH repetition timings associated with PDCCH candidate indexes that meet the PDCCH candidate index thresholds.

[0081] The reference repetition timing may include the PDCCH repetition timing associated with the starting CCE index that satisfies the starting control channel element (CCE) index condition. For example, the reference repetition timing may include the PDCCH repetition timing associated with the highest CCE index among the CCE indices associated with the repetition timing, the PDCCH repetition timing associated with the lowest CCE index, and / or the PDCCH repetition timing associated with the CCE index that satisfies the CCE index threshold.

[0082] The reference repetition timing may include the PDCCH repetition timing associated with a TCI state ID that satisfies the TCI state ID condition. For example, the reference repetition timing may include the PDCCH repetition timing associated with the highest TCI state ID among the TCI state IDs associated with the repetition timing, the PDCCH repetition timing associated with the lowest TCI state ID, and / or the PDCCH repetition timing associated with a TCI state ID that satisfies the TCI state ID threshold.

[0083] The reference repetition timing may include a PDCCH repetition timing associated with the ID of the antenna panel corresponding to the panel ID condition. For example, the reference repetition timing may include a PDCCH repetition timing associated with the TCI status ID of the antenna port in the quasi-co-located (QCL) antenna port associated with the highest SSB index in the Synchronization Signal Block (SSB) index associated with the same repetition timing, a PDCCH repetition timing associated with the TCI status ID of the antenna port in the QCL antenna port associated with the lowest SSB index, and / or a PDCCH repetition timing associated with the TCI status ID of the antenna port in the QCL antenna port associated with the SSB index that meets the SSB index threshold. In some aspects, the reference repetition timing may include a PDCCH repetition timing associated with the highest panel ID and / or TRP ID, a PDCCH repetition timing associated with the lowest panel ID and / or TRP ID, and / or a PDCCH repetition timing associated with the panel ID and / or TRP ID that meets the panel ID threshold.

[0084] In some aspects, for example, beam parameters may include the duration for applying a non-default beam. Wireless communication device 405 may identify a reference repetition timing and determine the duration for applying the non-default beam, at least in part, based on applying a time offset to the start time. The start time may correspond to a reference repetition timing. According to some aspects, the duration for applying the non-default beam may be specified as a timeDurationforQCL variable. The timeDurationforQCL variable may be determined as the duration between a reference time timing for receiving DL DCI and the corresponding PDSCH (e.g., scheduled via DCI), which enables wireless communication device 405 to prepare the indicated new beam for receiving PDSCH communication. The reference time timing may be determined as a reference repetition timing, as described above, and may be one or more reference PDCCH repetition timings described above regarding the determination of the application of the beam indicator.

[0085] In some aspects, beam parameters may include beam switching timing, which can be specified as a beamSwitchTiming variable. The wireless communication device 405 can identify a reference repetition timing and determine the beam switching timing, at least in part, based on applying a time offset to the start time, where the start time corresponds to the reference repetition timing. The beamSwitchTiming variable can be specified as the duration between the last symbol of the PDCCH reference repetition timing carrying the trigger DCI and the first symbol of the aperiodic CSI-RS resource, enabling the wireless communication device 405 to prepare the indicated new beam for receiving the CSI-RS resource.

[0086] In some aspects, beam parameters may include beam reset timing associated with a beam failure recovery process. For example, beam parameters may include beam reset timing following a response from the base station to the beam failure recovery process. Wireless communication device 405 may identify a reference repetition timing and determine the beam reset timing, at least in part, based on applying a time offset to a start time, where the start time corresponds to the reference repetition timing. The start time may be the last symbol of the reference repetition timing.

[0087] In some aspects, at least one channel repetition may include multiple PDCCH repetitions, and a reference repetition may include the last PDCCH repetition timing among multiple PDCCH repetition timings corresponding to the multiple PDCCH repetitions. For example, beam reset timing may be defined as 28 symbols from the last PDCCH reception timing if multiple PDCCH receptions are linked using a DCI format that schedules PUSCH receptions with the same HARQ procedure number as the HARQ procedure number used for the transmission of the first PUSCH. For example, the UE may be configured for PUCCH transmissions with a Link Recovery Request (LRR) via the parameter schedulingRequestID-BFR-SCell-r16. The UE may transmit a Medium Access Control (MACCE) element in the first Physical Uplink Shared Channel (PUSCH) that provides one or more indices for at least one or more corresponding SCells with radio link quality worse than a quality threshold, and one or more indices q for the corresponding secondary cell (SCell). new One or more indications of existence, and an index q provided by a higher layer (if any) for the corresponding SCell for periodic CSI-RS configuration or for the Synchronization Signal / Physical Broadcast Channel (SS / PBCH) block. new After 28 symbols following the last PDCCH reception, or if multiple PDCCH receptions are linked using a DCI format that schedules PUSCH transmissions with the same HARQ procedure number as the one used for the first PUSCH transmission and has a New Data Indicator (NDI) field value for switching, the UE can use the corresponding index q. new (If applicable) The antenna port quasi-co-address parameters are the same as those associated with the PDCCH in all core resource sets (CORESET) on the SCell indicated by MAC CE, and can be used with the q parameters used for periodic CSI-RS or SS / PBCH block reception. new The corresponding spatial filter is the same spatial filter used to send PUCCH on PUCCH-SCell.

[0088] In some aspects, for PCell or PSCell, the beam reset timing may have a start time associated with 28 symbols from the last symbol of the first PDCCH received in the search space set provided by the parameter recoverySearchSpaceId for its UE, which has a DCI format scrambled by C-RNTI or MCS-C-RNTI, or the last PDCCH received if multiple PDCCH receives are linked to the first PDCCH receive, and until the UE receives an activation command for the parameter PUCCH-SpatialRelationInfo or is provided with PUCCH-SpatialRelationInfo for PUCCH resources. In some aspects, for PCell or PSCell, the beam reset timing may have a start time associated with the last symbol of the first PDCCH received in the search space set provided by the parameter recoverySearchSpaceId, in which the UE detects a DCI format scrambled with a CRC by C-RNTI or MCS-C-RNTI, or, if multiple PDCCH receptions are linked to the first PDCCH reception, the last PDCCH reception.

[0089] In some aspects, beam parameters include TPC applicable timing, and the wireless communication device 405 can identify the reference repetition timing, and determine the TPC applicable timing at least in part based on applying a time offset to the start time. The start time may correspond to the reference repetition timing. In some aspects, the start time may include the last symbol of the reference repetition timing.

[0090] For example, if the PUSCH transport is scheduled via DCI format, then K PUSCH (i) can be the number of active UL BWP b symbols for carrier f serving cell C, after the last symbol of the corresponding PDCCH reception or, if multiple PDCCH receptions are linked to a PDCCH reception, before the first symbol of the PUSCH transmission. In some aspects, if the PUCCH transmission is in response to the UE detecting DCI format 1_0 or DCI format 1_1, then K PUCCH (i) can be the number of active UL BWP b symbols for carrier f of primary cell C, after the last symbol of the corresponding PDCCH reception or, if multiple PDCCH receptions are linked to a PDCCH reception, before the first symbol of the PUCCH transmission. In some aspects, if the SRS transmission is aperiodic, then K SRS(i) can be the number of active UL BWP b symbols for carrier f serving cell C after the last symbol of the corresponding PDCCH that triggers the SRS transmission, or if multiple PDCCH receptions are linked to the PDCCH reception, after the last PDCCH reception timing and before the first symbol of the SRS transmission.

[0091] In some aspects, beam parameters may include CPU occupancy duration. Wireless communication device 405 may identify a reference repetition timing and determine the CPU occupancy duration, at least in part, based on applying a time offset to a start time. The start time may correspond to a reference repetition timing. For example, the start time may include the last symbol of the reference repetition timing. In some aspects, a reference repetition may include the last PDCCH repetition timing among multiple PDCCH repetition timings corresponding to multiple PDCCH repetitions.

[0092] For example, in some aspects, aperiodic CSI reporting may occupy one or more CPUs from the first symbol after the PDCCH that triggers the CSI report, or the last PDCCH reception timing if multiple PDCCH receptions are linked to PDCCH reception, and up to the last symbol between the first symbol after the PDCCH that triggers the CSI report, or the last PDCCH reception timing if multiple PDCCH receptions are linked to PDCCH reception, and the last symbol between the last symbol of the most recent CSI-RS / SSB resource in each CSI-RS / SSB resource used for channel measurements for L1-RSRP calculation.

[0093] In some aspects, for joint or individual DL / UL beam indications within a unified TCI framework, when a beam indication is received, the application time of the beam indication can be a first time slot separated by a time offset from the reference PUCCH or PUSCH repetition in multiple PUCCH or PUSCH repetition timings. For example, the time offset can be X milliseconds, X time slots, or Y symbols after the reference PUCCH or PUSCH repetition timing. The reference PUCCH or PUSCH repetition timing can be as follows (see reference below). Figure 5 Further description is needed to determine this.

[0094] In some aspects, when receiving an indication that a common TCI state ID update and activation is provided for the component carrier set configured across a carrier aggregation configuration, providing common QCL information and / or common UL transmission space filter, the wireless communication device 405 may apply one or more activated TCIs starting from a first time slot after time slot k+X, where k is the time slot in which the wireless communication device 405 will transmit a PUCCH or PUSCH timing carrying an acknowledgment corresponding to the indication for the common TCI state ID update. The PUCCH or PUSCH repetition carrying this indication may correspond to a reference repetition timing, which may be as follows: Figure 6 Further description is needed to determine this.

[0095] As indicated by reference numeral 430, wireless communication device 405 may perform wireless communication actions based at least in part on determinations associated with beam parameters. For example, in some aspects, wireless communication device 405 may apply an indicated beam, apply a default beam, and / or update a beam, among other examples.

[0096] 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.

[0097] Figure 5 This is a schematic diagram illustrating Example 500 associated with beam parameter determination for channel repetition according to various aspects of this disclosure. Example 500 shows a first time slot 505 (shown as "k1 time slot") and a second time slot 510 (shown as "k2 time slot"), wherein a PUCCH repetition timing or a PUSCH repetition timing is scheduled (shown as "PUCCH / PUSCH"). Each PUCCH / PUSCH repetition timing can be configured to carry an acknowledgment (shown as "ACK") of received joint or individual DL / UL beam indications.

[0098] In some aspects, for joint or individual DL / UL beam indications within a unified TCI framework, when a beam indication is received, the application time of the beam indication can be a first time slot separated from the reference PUCCH or PUSCH repetition in multiple PUCCH or PUSCH repetition timings by a time offset. The time offset can be, for example, X milliseconds, X time slots, or Y symbols after the reference PUCCH or PUSCH repetition timing.
