Technical Field

[0003] In summary, various aspects of this disclosure relate to wireless communications, and to techniques and apparatus for designing joint hybrid automatic repeat request (HARQ) timing and start and length indicator values ​​(SLIV) for multi-physical downlink shared channel (multi-PDSCH) permission. 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 can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / 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 multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with the BS 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.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be referred to as 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

[0030] 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 the disclosure made 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 those set forth herein or different from those set forth herein. It should be understood that any aspect of this disclosure made herein may be embodied by one or more elements of the claims.

[0031] 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 the following detailed embodiments 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.

[0032] It should be noted that although terms commonly associated with 5G or NR radio access technology (RAT) may be used in this document to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0033] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, or may include elements of a 5G (NR) network and / or an LTE network. The wireless network 100 may include multiple 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, Transmit / Receive Point (TRP), etc. Each BS can provide communication coverage for a specific geographic area. In 3GPP, depending on the context in which the term "cell" is used, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area.

[0034] 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.

[0035] 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 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0036] 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 to 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.

[0037] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, repeater 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 repeater BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0038] 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.

[0039] 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 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.

[0040] 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, meters, monitors, and / or location tags, 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 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 that houses the components of UE 120 (e.g., 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.

[0041] 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.

[0042] 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.

[0043] 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). The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) bands. 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 explicitly 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 intermediate frequency band frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise explicitly 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 intermediate frequency band frequencies (e.g., below 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0044] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 As described.

[0045] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to the present 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 generally, T ≥ 1 and R ≥ 1.

[0046] At base station 110, transmit processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for the UE based at least in part on channel quality indicators (CQI) received from each UE, process (e.g., code and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmit 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. Transmit 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 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.

[0047] 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, down-convert, 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 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. 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 parameters such as the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), and / or CQI. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0048] 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 a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0049] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within the following: one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements.

[0050] 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.

[0051] 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.

Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 5-12 (Described).

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...

[0067] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above with respect to these boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of controller / processor 280.

[0068] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 As described.

[0069] Figure 3 This is a diagram illustrating example 300 of physical channels and reference signals in a wireless network according to this disclosure. Figure 3As shown, the downlink channel and downlink reference signal can carry information from base station 110 to UE 120, while the uplink channel and uplink reference signal can carry information from UE 120 to base station 110.

[0070] As shown in the figure, downlink channels may include a Physical Downlink Control Channel (PDCCH) carrying downlink control information (DCI), a Physical Downlink Shared Channel (PDSCH) carrying downlink data, or a Physical Broadcast Channel (PBCH) carrying system information, etc. In some aspects, PDSCH communication can be scheduled through PDCCH communication. As further shown, uplink channels may include a Physical Uplink Control Channel (PUCCH) carrying uplink control information (UCI), a Physical Uplink Shared Channel (PUSCH) carrying uplink data, or a Physical Random Access Channel (PRACH) for initial network access, etc. In some aspects, UE 120 may send acknowledgment (ACK) or negative acknowledgment (NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) in the UCI on the PUCCH and / or PUSCH.

[0071] As further illustrated, downlink reference signals may include synchronization signal blocks (SSBs), channel state information (CSI) reference signals (CSI-RS), DMRS, positioning reference signals (PRS), or phase tracking reference signals (PTRS), etc. Additionally, as shown in the figure, uplink reference signals may include sounding reference signals (SRS), DMRS, or PTRS, etc.

[0072] SSBs can carry information for initial network acquisition and synchronization, such as PSS, SSS, PBCH, and PBCH DMRS. SSBs are sometimes referred to as synchronization signal / PBCH (SS / PBCH) blocks. In some aspects, base station 110 can transmit multiple SSBs on multiple corresponding beams, and these SSBs can be used for beam selection.

[0073] CSI-RS can carry information for downlink channel estimation (e.g., downlink CSI acquisition), which can be used for scheduling, link adaptation, or beam management. Base station 110 can configure a set of CSI-RS for UE 120, and UE 120 can measure the configured set of CSI-RS. Based at least in part on the measurement, UE 120 can perform channel estimation and can report channel estimation parameters to base station 110 (e.g., in a CSI report), such as CQI, precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), layer indicator (LI), rank indicator (RI), or RSRP. Base station 110 can use the CSI report to select transmission parameters for downlink communication to UE 120, such as the number of transport layers (e.g., rank), precoding matrix (e.g., precoder), MCS, or refined downlink beams (e.g., using a beam refinement process or beam management process).

[0074] The DMRS can carry information used to estimate the radio channel for demodulating the associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH). The design and mapping of the DMRS can be specific to the physical channel estimated for it. The DMRS is UE-specific, can be beamformed, can be confined to scheduled resources (e.g., not transmitted over broadband), and can be transmitted only when necessary. As shown, the DMRS is used for both downlink and uplink communication.

[0075] PTRS can carry information for compensating oscillator phase noise. Typically, phase noise increases with the oscillator carrier frequency. Therefore, PTRS can be used to mitigate phase noise at high carrier frequencies (such as millimeter-wave frequencies). PTRS can be used to track the phase of the local oscillator and suppress phase noise and common phase error. As shown, PTRS is used for both downlink communication (e.g., on PDSCH) and uplink communication (e.g., on PUSCH).

[0076] The PRS can carry information for improving the Observed Time Difference of Arrival (OTDOA) positioning performance of UE 120 based on timing or ranging measurements of signals transmitted by base station 110. For example, the PRS can be a pseudo-random quadrature phase shift keying (QPSK) sequence mapped in frequency and time in a shifted diagonal pattern to avoid conflicts with cell-specific reference signals and control channels (e.g., PDCCH). Typically, the PRS can be designed to improve the detectability of UE 120, which may need to detect downlink signals from multiple neighboring base stations to perform OTDOA-based positioning. Therefore, UE 120 can receive PRS from multiple cells (e.g., a reference cell and one or more neighboring cells) and can report the Reference Signal Time Difference (RSTD) based on the OTDOA measurements associated with the PRS received from the multiple cells. In some aspects, base station 110 can then calculate the location of UE 120 based on the RSTD measurements reported by UE 120.

[0077] The SRS can carry information for uplink channel estimation, which can be used for scheduling, link adaptation, precoder selection, or beam management. Base station 110 can configure one or more SRS resource sets for UE 120, and UE 120 can transmit SRS on the configured SRS resource sets. The SRS resource sets can have configurable uses, such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operations, and uplink beam management. Base station 110 can measure the SRS, can perform channel estimation at least partially based on the measurement, and can use the SRS measurement to configure communication with UE 120.

[0078] As indicated above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 As described.

[0079] Figure 4 This is a diagram illustrating example 400 of a frame structure in a wireless communication network according to this disclosure. Figure 4 The frame structure shown is for Frequency Division Duplex (FDD) in telecommunications systems such as LTE and / or NR. The transmission timeline for each of the downlink and uplink can be divided into units called radio frames (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z≥1) subframes (e.g., with indices from 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., such as...). Figure 4As shown, each subframe has 2m time slots, where m is an index of the digital scheme (numerology) used for transmission, such as 0, 1, 2, 3, or 4. Each time slot can include a set of L symbol periods. For example, each time slot can include fourteen symbol periods (e.g., as shown in the diagram). Figure 4 (as shown in the diagram), seven symbol periods, or another number of symbol periods. In the case where a subframe comprises two time slots (e.g., when m = 1), the subframe may comprise 2L symbol periods, wherein the 2L symbol periods in each subframe can be assigned indices from 0 to 2L-1. In some aspects, the scheduling unit for FDD can be frame-based, subframe-based, time slot-based, micro-time slot-based, or symbol-based.

[0080] As indicated above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 As described.

[0081] In some aspects, base stations can use multiple PDSCH grants to schedule downlink communications to the UE. In this case, the base station can use a single downlink grant to schedule multiple PDSCH transmissions to the UE. This can reduce the control overhead associated with scheduling downlink transmissions to the UE. Furthermore, time slots for communication in millimeter-wave bands may be shorter compared to communication in sub-6 GHz bands, especially when using higher subcarrier spacing (SCS). In this case, multiple PDSCH grants allow the base station to schedule longer downlink bursts.

[0082] The base station can send a Data Interchange Indicator (DCI) to the UE indicating parameters associated with multi-PDSCH permission. The base station can use the same Frequency Domain Resource Allocation (FDRA), Modulation and Coding Scheme (MCS), rank, precoding, and / or other transmission parameters for multiple PDSCH transmissions to the UE. In some cases, the multi-PDSCH DCI can indicate a first HARQ process identifier (ID) for HARQ feedback for the first PDSCH transmission, and the UE can use incremental HARQ process IDs for HARQ feedback for subsequent PDSCH transmissions. In some cases, the base station can use a separate New Data Indicator (NDI) and a separate Compressed Redundancy Version Identifier (RVID) for each PUSCH transmission.

[0083] A multi-PDSCH DCI can indicate the TDRA used for multiple PDSCH transmissions. For example, a DCI can include a corresponding SLIV indicating the start symbol and length (e.g., number of symbols) in a time slot for each PDSCH transmission. The same SLIV can be used to indicate the TDRA used for multiple PDSCH transmissions across multiple time slots. A multi-PDSCH DCI can also indicate a PDSCH-to-HARQ feedback timing value, which may be referred to as the K1 value in the 3GPP standard. The PDSCH-to-HARQ feedback timing value can indicate the time offset (e.g., the number of time slots, sub-time slots, or symbols) between the last time slot, sub-time slot, or symbol of a PDSCH communication and the time slot, sub-time slot, or symbol in which HARQ feedback corresponding to the PDSCH communication is to be transmitted. Therefore, the PDSCH-to-HARQ feedback timing value can indicate the corresponding time slot, sub-time slot, or symbol in which HARQ feedback for one or more PDSCH communications is to be transmitted. The PDSCH-to-HARQ feedback timing value may be referred to herein as the PDSCH-to-HARQ timing value or the K1 value.

[0084] In some cases, when using multi-PDSCH permission to schedule multiple PDSCH communications, the TDRA for one or more PDSCH communications may conflict with the timing of the HARQ feedback sent by the UE corresponding to one or more earlier PDSCH communications. This can result in delayed or undelivered HARQ feedback for one or more PDSCH communications, potentially reducing network reliability and increasing network latency. In some cases, the base station may pre-configure SLIV and K1 values ​​to define non-conflicting TDRA and HARQ feedback patterns.

[0085] Some of the techniques and apparatus described herein enable a UE to receive permission to schedule multiple downlink (e.g., PDSCH) communications and to determine, at least in part, whether there is a conflict between uplink feedback communication for at least one first downlink communication and TDRA for a second downlink communication, based on SLIV and K1 values ​​included in the permission. The UE can adjust the timing of the TDRA and / or uplink feedback communication for the second downlink communication, at least in part, based on the determination of a conflict. Therefore, the UE can dynamically adjust the TDRA and / or feedback timing to avoid conflicts between scheduled downlink communications and uplink feedback communication. This prevents feedback for one or more downlink communications scheduled via multi-PDSCH permission from being delayed and / or dropped due to a conflict with another downlink communication scheduled via multi-PDSH permission, which can increase network reliability and reduce network latency. Furthermore, since the UE dynamically adjusts the TDRA and / or feedback timing based on the determination of a conflict, the TDRA does not need to be adjusted for non-conflicting downlink communications. This increases scheduling flexibility permitted by multiple PDSCHs compared to pre-configuring SLIV and K1 values ​​to define conflict-free downlink TDRA and feedback timing patterns.

[0086] Figure 5 This is a diagram illustrating Example 500 associated with a joint HARQ timing and SLIV design for multi-PDSCH permission, according to this disclosure. Figure 5 As shown, Example 500 includes communication between base station 110 and UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network (such as wireless network 100). Base station 110 and UE 120 may communicate via a radio access link, which may include an uplink and a downlink.

[0087] As in Figure 5As shown by reference numeral 505, base station 110 can send permission to UE 120 to schedule multiple downlink communications. For example, base station 110 can send a multi-PDSCH permission to UE 120 to schedule multiple PDSCH communications. The permission may include multiple SLIVs and a K1 value, where the multiple SLIVs include a corresponding SLIV for each downlink communication in the multiple downlink communications. Each SLIV may indicate the TDRA for the corresponding downlink communication. For example, the SLIV may indicate the start symbol and length (e.g., number of symbols) to be used for each downlink communication in the corresponding time slot. The K1 value may indicate the timing of uplink feedback communications (e.g., PUCCH communications) for the multiple downlink communications. For example, the K1 value may indicate the time offset between the downlink communication and the uplink HARQ feedback response for the downlink communication. The permission may be included in a DCI (e.g., a multi-PDSCH DCI). For example, the DCI may include SLIVs and K1 values ​​for the multiple downlink communications. In some aspects, DCI may also include indications of other parameters associated with multiple downlink communications, such as MCS, FDRA, rank, precoding, and / or initial HARQ process ID.

[0088] As in Figure 5 Furthermore, as shown in Appendix Figure 510, UE 120 can determine, at least in part, based on the SLIV and K1 values, that there is a conflict between the timing of the uplink feedback communication for a first downlink communication (or for a plurality of previous downlink communications) and the TDRA for a second downlink communication in a plurality of downlink communications. UE 120 can determine, at least in part, based on the TDRA and K1 values ​​for the second downlink communication, the PUCCH Resource Indicator (PRI) for transmitting the PUCCH resource for transmitting the uplink feedback communication (e.g., a HARQ feedback response) for the first downlink communication. In some aspects, UE 120 can determine that the timing of the PUCCH resource for transmitting the uplink feedback communication may overlap with one or more symbols in the TDRA for the second downlink communication.

[0089] For example, such as Figure 5 As shown, UE 120 can receive multiple PDSCH DCIs, which schedule first PDSCH communication in a first time slot and second PDSCH communication in a second time slot. SLIV can indicate that the TDRA for each of the first and second PDSCH communications begins at the beginning of the corresponding time slot and has the length of all symbols in the corresponding time slot (e.g., 14 symbols). UE 120 can determine that the PRI for uplink feedback communication for the first PDSCH conflicts with the TDRA for the second PDSCH.

[0090] As in Figure 5 As further shown by reference numeral 515, UE 120 may adjust the timing of the conflicting downlink communication's TDRA and / or the conflicting uplink feedback communication, at least in part, based on the determination that a conflict exists. For example, UE 120 may adjust the TDRA for the second downlink communication, at least in part, based on the determination that a conflict exists between the timing of the uplink feedback communication for the first downlink communication and the TDRA for the second downlink communication. In some aspects, UE 120 may adjust the TDRA for the second downlink communication, at least in part, based on the timing of the conflicting uplink feedback communication, to leave a gap for UE 120 to transmit the uplink feedback communication. In this case, UE 120 may adjust the original TDRA for the second downlink communication to determine the adjusted TDRA for the second downlink communication and the gap for the uplink feedback communication.

[0091] In some aspects, the original TDRA for second downlink communication may include a set of symbols for transmitting the second downlink communication. UE 120 may divide the set of symbols in the original TDRA into multiple symbol subsets and group the subsets into an adjusted TDRA for second downlink communication or a gap for uplink feedback communication. For example, in Figure 5 As shown in the example, UE 120 can divide the symbols in the original TDRA used for second downlink communication (e.g., second PDSCH) into five subsets: S0, S1, S2, S3, and S4. In some aspects, UE 120 can divide the symbols into different numbers of subsets. For example, in some aspects, UE 120 can combine them into... Figure 5 Two or more subsets of the subset shown.

[0092] Each of these subsets (S0, S1, S2, S3, and S4) may include the corresponding symbol sequence in the original TDRA. As used herein, “S2” may refer to one or more symbols used for transmitting uplink feedback communication (e.g., uplink feedback communication for the first PDSCH). That is, S2 may be one or more symbols corresponding to the PRI used for uplink feedback communication determined according to the K1 value. As used herein, “S1” may refer to the subset of symbols preceding S2 that provide the downlink-to-uplink handover gap. For example, the downlink-to-uplink handover gap (S1) may correspond to the amount of time for UE 120 to switch from receiving downlink communication to transmitting uplink communication. For example, the downlink-to-uplink handover gap (S1) may correspond to the amount of time for UE 120 to switch from receiving downlink communication to transmitting uplink communication. As used herein, “S3” may refer to the subset of symbols following S2 that provide the uplink-to-downlink handover gap. For example, the uplink-to-downlink handover gap (S3) can correspond to the amount of time that allows UE120 to switch from sending uplink communication to receiving downlink communication.

[0093] In some aspects, the number of symbols in S1 and / or the number of symbols in S3 can be configured by base station 110. For example, base station 110 can send configuration information (e.g., Radio Resource Control (RRC) configuration information) to UE 120, which includes an indication of the length of S1 and / or the length of S3. In some aspects, base station 110 can determine the length of S1 and / or the length of S3 based at least in part on the capabilities of UE 120. For example, base station 110 can configure S1 and / or S3 based at least in part on UE capability information received from UE 120. In some aspects, the length of S3 can be configured to zero. In this case, S3 can be combined with S4.

[0094] As used herein, “S0” may refer to the subset of symbols preceding S1 in the original TDRA. As used herein, “S4” may refer to the subset of symbols following S3 in the original TDRA. If S3 is configured to 0 (e.g., no subset S3 exists), S4 may include symbols following S2 in the original TDRA. The lengths of S0 and / or S4 may depend on the position of the PRI (S2) for uplink feedback communication in the original TDRA.

[0095] In some aspects, UE 120 may eliminate at least S2 and S1 from the original TDRA used for second downlink communication. In some aspects, UE 120 may determine an adjusted TDRA for second downlink communication to include S0 (e.g., the symbol preceding S1) in the original TDRA, and UE 120 may determine a gap for uplink feedback communication to include S1, S2, and any symbols following S2 in the original TDRA (e.g., S3 and S4). In this case, if PRI is located in the middle of the original TDRA, S4 may not be usable.

[0096] In some aspects, if the PRI is located in the middle of the original TDRA, the UE 120 can determine an adjusted TDRA for the second downlink communication to include S0 (e.g., symbols before S1) and S4 (e.g., symbols after S3), and the UE 120 can determine a gap for uplink feedback communication to include S1, S2, and S3. In this case, the base station 110 can use Type B scheduling to schedule separate transmissions of the second downlink communication (e.g., PDSCH communication) in S0 and S4. For example, the base station 110 can perform a first transmission of a transport block (TB) in S0, and the base station 110 can perform a second transmission of the same TB in S4. In some aspects, the base station 110 can use different RVIDs for the first and second transmissions.

[0097] In some aspects, UE 120 can adjust the timing of the TDR for the second downlink communication and the timing of conflicting uplink feedback communication to determine the adjusted TDR and the gap for the uplink feedback communication. In some aspects, UE 120 can shift the timing for the uplink feedback communication to the end of the original TDR. For example, UE 120 can shift S2 to the last subset of symbols in the original TDR, and UE 120 can shift S1 to the subset of symbols immediately preceding S2. UE 120 can then include all symbols preceding S1 and S2 in the adjusted TDR.

[0098] As in Figure 5 Furthermore, as shown by reference numeral 520 in the accompanying drawings, base station 110 can also determine the existence of a conflict at least in part based on the SLIV and K1 values, as described above in conjunction with UE 120. Base station 110 can also determine the adjusted TDRA and the gap for feedback timing, as described above in conjunction with UE 120. Therefore, base station 110 can adjust the TDRA used for downlink communication to be the same as the adjusted TDRA determined by UE 120.

[0099] As in Figure 5As further shown by reference numeral 525, base station 110 can send multiple downlink communications (e.g., PDSCH) to UE 120. If UE 120 has adjusted the TDRA for downlink communications (e.g., a second downlink communication) based on conflicts with uplink feedback communications, base station 110 can determine an adjusted TDRA for downlink communications that is the same as the adjusted TDRA determined by UE 120, and base station 110 can send downlink communications within the adjusted TDRA determined for downlink communications.

[0100] As in Figure 5 As further shown by reference numeral 530 in the accompanying drawings, UE 120 can send uplink feedback communications (e.g., PUCCH feedback communications) to base station 110 for downlink (e.g., PDSCH) communications received from base station 110. For example, UE 120 can send PUCCH communications to base station 110 including HARQ ACK or HARQ NACK for each downlink communication received from base station 110. UE 120 can send uplink feedback communications in gaps determined by UE 120 within the TDRA used for downlink communications.

[0101] As mentioned above Figure 5 As described, base station 110 can send permission to schedule multiple downlink communications to UE 120. UE 120 can determine, at least in part, whether there is a conflict between uplink feedback communication for a first downlink communication and TDRA for a second downlink communication, based on the SLIV and K1 values ​​included in the permission. UE 120 can adjust the timing of the TDRA and / or uplink feedback communication for the second downlink communication, at least in part, based on the determination of a conflict. This prevents feedback for downlink communications scheduled via multi-PDSCH permission from being delayed and / or dropped due to conflicts with other downlink communications scheduled via multi-PDSH permission, which can increase network reliability and reduce network latency. Furthermore, since the UE dynamically adjusts the TDRA and / or feedback timing based on the determination of a conflict, base station 110 or UE 120 does not need to configure and store a large table of non-conflicting SLIV and K1 values, thus saving computational and memory resources.

[0102] As indicated above, Figure 5 This is provided as an example. Other examples may differ from the one provided. Figure 5 As described.

[0103] Figure 6 This is a diagram illustrating Example 600 associated with a joint HARQ timing and SLIV design for multi-PDSCH permission, according to this disclosure. Figure 6 As shown, in Example 600, the UE can receive multiple PDSCH DCIs, which schedule first PDSCH communication in a first time slot and second PDSCH communication in a second time slot. SLIV can indicate that the TDRA for each of the first and second PDSCH communications begins at the start of the corresponding time slot and has the length of all symbols in the corresponding time slot (e.g., 14 symbols). The K1 value can indicate the time slot offset between the time slot of the first PDSCH and the time slot containing the PUCCH timing for uplink feedback for the first PDSCH. UE 120 can determine that the PRI for uplink feedback communication for the first PDSCH conflicts with the TDRA for the second PDSCH.

[0104] like Figure 6 As shown, the UE can eliminate S1-S4 from the original TDRA of the second PDSCH. In this case, the UE can determine the adjusted TDRA for the second PDSCH to include S0 (e.g., the symbol before S1) in the original TDRA, and the UE can determine the gap for uplink feedback communication to include S1-S4. In some aspects, the base station can adjust the transmission of the second PDSCH at least in part based on the adjusted TDRA for the second PDSCH. For example, the base station can rate match the second PDSCH at least in part based on S0.

[0105] As indicated above, Figure 6 This is provided as an example. Other examples may differ from the one provided. Figure 6 As described.

[0106] Figure 7 This is a diagram illustrating Example 700 associated with a joint HARQ timing and SLIV design for multi-PDSCH permission, according to this disclosure. Figure 7 As shown, in Example 700, the UE can receive multiple PDSCH DCIs, which schedule first PDSCH communication in a first time slot and second PDSCH communication in a second time slot. SLIV can indicate that the TDRA for each of the first and second PDSCH communications begins at the start of the corresponding time slot and has the length of all symbols in the corresponding time slot (e.g., 14 symbols). The K1 value can indicate the time slot offset between the time slot of the first PDSCH and the time slot containing the PUCCH timing for uplink feedback for the first PDSCH. The UE can determine that the PRI for uplink feedback communication for the first PDSCH conflicts with the TDRA for the second PDSCH.

[0107] like Figure 7As shown, the UE can eliminate S1-S3 from the original TDRA of the second PDSCH. In this case, the UE can determine that the adjusted TDRA for the second PDSCH includes S0 (e.g., the symbols before S1) and S4 (e.g., the symbols after S3). The UE can determine the gap for uplink feedback communication to include S1, S2, and S3. In this case, the base station can use Type B scheduling to schedule separate transmissions of the second PDSCH communication in S0 and S4. For example, the base station can perform a first transmission of TB in S0, and the base station can perform a second transmission of the same TB in S4. In some aspects, the base station can use different RVIDs for the first and second transmissions. Type B PDSCH scheduling can utilize at least two symbols. Therefore, in some aspects, if S0 or S4 is a symbol long, the UE may not include that subset in the adjusted TDRA for the second PDSCH. In some respects, when the PRI is in the middle of the original TDRA, using S0 and S4 for Type B microslot scheduling of PDSCH transmission can provide more efficient use of resources compared to using only S0 or S4.

[0108] As indicated above, Figure 7 This is provided as an example. Other examples may differ from the one provided. Figure 7 As described.

[0109] Figure 8 This is a diagram illustrating an example 800 associated with a joint HARQ timing and SLIV design for multi-PDSCH permission, according to this disclosure. Figure 8 As shown, in Example 800, the UE can receive multiple PDSCH DCIs, which schedule first PDSCH communication in a first timeslot and second PDSCH communication in a second timeslot. The K1 value can indicate the timeslot offset between the timeslot containing the first PDSCH and the timeslot containing the PUCCH for uplink feedback to the first PDSCH. UE 120 can determine that the PRI for uplink feedback communication to the first PDSCH conflicts with the TDRA for the second PDSCH.

[0110] like Figure 8As shown, the UE can move uplink resources used for uplink feedback communication to the end of the original TDRA used for the second PDSCH. For example, the UE can move S2 to the last subset of symbols in the original TDRA, and the UE can move S1 to the subset of symbols immediately preceding S2. The UE can then include all symbols preceding S1 and S2 in the adjusted TDRA. By moving S1 and S2 to the end of the original TDRA, the UE sets S3 = S4 = 0 and adjusts S0 such that the number of symbols in the adjusted S0 (e.g., the subset of symbols preceding S1) is equal to S0 + S3 + S4 in the original TDRA. This allows the UE to shorten the original TDRA only to S1 + S2 and group the remaining symbols together for the adjusted PDSCH TDRA, which increases the resources available for the second PDSCH communication. Furthermore, in this case, the base station can configure S1 without configuring S3, which reduces control signaling overhead.

[0111] As indicated above, Figure 8 This is provided as an example. Other examples may differ from the one provided. Figure 8 As described.

[0112] Figure 9 This is a diagram illustrating example 900 associated with a joint HARQ timing and SLIV design for multi-PDSCH permission, according to this disclosure. Figure 9 As shown, Example 900 includes communication between base station 110 and UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network (such as wireless network 100). Base station 110 and UE 120 may communicate via a radio access link, which may include an uplink and a downlink.

[0113] As in Figure 9 As shown by reference numeral 905 in the accompanying drawings, base station 110 can determine the SLIV and K1 values ​​to configure permission for multiple downlink communications (e.g., multiple PDSCH permission), which has a TDRA that does not conflict with uplink feedback communications (e.g., PUCCH feedback communications) for downlink communications. Base station 110 can determine the SLIV to configure the TDRA for transmitting multiple downlink communications in corresponding time slots. In some aspects, base station 110 can determine the SLIV to configure the TDRA to leave a gap including one or more symbols at the end of each time slot. In this case, the TDRA for each downlink communication can be less than the length of the time slot.

[0114] In some aspects, base station 110 can determine a K1 value such that the time offset starting from the end of downlink communication places the uplink feedback for that downlink communication at the end of the time slot following the time slot in which the downlink communication was scheduled. In some aspects, the uplink feedback communication can be for multiple previous downlink communications. For example, in... Figure 9 As shown in the example, base station 110 can include SLIV and K1 values ​​in the multi-PDSCH DCI scheduling of the first PDSCH in the first time slot and the second PDSCH in the second time slot. Base station 110 can determine the SLIV to leave a gap of length S1+S2 at the end of each time slot. Base station 110 can determine the K1 value such that the PUCCH resources for uplink feedback communication for the first PDSCH communication are in the gap at the end of the second time slot. In this case, base station 110 can pre-configure the gap of S1+S2 and the TDRA of S0 for each PDSCH communication.

[0115] As in Figure 9 As further shown by reference numeral 910 in the accompanying drawings, base station 110 can send multiple downlink communication permissions (e.g., multiple PDSCH permissions) to UE 120. These permissions may include SLIV and K1 values ​​determined by base station 110.

[0116] As in Figure 9 As further shown by reference numeral 915, base station 110 can transmit multiple downlink (e.g., PDSCH) communications to UE 120, at least in part, based on a TDRA configured by SLIV. For example, base station 110 can transmit multiple downlink communications within multiple time slots in the TDRA, with a gap left at the end of each time slot.

[0117] As in Figure 9 As further shown by reference numeral 920 in the accompanying drawings, UE 120 can send uplink feedback communications (e.g., PUCCH feedback communications) to base station 110 for multiple downlink communications received from base station 110. UE 120 can also send uplink feedback communications (e.g., PUCCH feedback communications) to base station 110 for downlink (e.g., PDSCH) communications received from base station 110. For example, UE 120 can send PUCCH communications to base station 110 including HARQ ACK or HARQ NACK for each downlink communication received from base station 110. Based at least in part on the K1 value, UE 120 can send uplink feedback communications in the gap at the end of a time slot. For example, UE 120 can receive a first downlink communication in a first time slot, and UE 120 can send uplink feedback communications for the first downlink communication in the gap at the end of a second time slot.

[0118] As mentioned above Figure 9 As described, base station 110 can determine SLIV and K1 values ​​to configure permission for multiple downlink communications, which have a TDRA that does not conflict with uplink feedback communications for downlink communications. Base station 110 can send this permission, which schedules multiple downlink communications and includes the SLIV and K1 values, to UE 120. In the case of multiple PDSCH permission, this can prevent conflicts between uplink feedback communications and downlink communications, which can increase network reliability and reduce network latency. Furthermore, this can reduce the processing time and resources that would otherwise be required for UE 120 to determine the existence of conflicts and adjust the TDRA and / or feedback timing.

[0119] As indicated above, Figure 9 This is provided as an example. Other examples may differ from the one provided. Figure 9 As described.

[0120] Figure 10 This is a diagram illustrating, for example, an example procedure 1000 performed by a UE according to this disclosure. Example procedure 1000 is an example in which a UE (e.g., UE 120) performs operations associated with joint HARQ timing and SLIV design for multi-PDSCH permission.

[0121] like Figure 10 As shown, in some aspects, process 1000 may include: receiving permission to schedule multiple downlink communications, wherein the permission includes multiple SLIVs indicating corresponding TDRAs for the multiple downlink communications and a feedback timing indicator (block 1010) indicating the timing of uplink feedback communications for the multiple downlink communications. For example, a UE (e.g., using...) Figure 13 The receiving component 1302 described herein can receive permission to schedule multiple downlink communications, wherein the permission includes multiple SLIVs indicating the corresponding TDRA for the multiple downlink communications and a feedback timing indicator indicating the timing of uplink feedback communications for the multiple downlink communications, as described above.

[0122] like Figure 10 As further shown, in some aspects, process 1000 may include: determining, at least in part, based on SLIV and a feedback timing indicator, that there is a conflict between the timing of a first uplink feedback communication for at least one first downlink communication in a plurality of downlink communications and a TDRA for a second downlink communication in a plurality of downlink communications (box 1020). For example, a UE (e.g., using in Figure 13The determining component 1308 described herein can determine, at least in part, a conflict between the timing of a first uplink feedback communication for at least one first downlink communication in a plurality of downlink communications and the TDRA for a second downlink communication in a plurality of downlink communications, based on the SLIV and the feedback timing indicator.

[0123] like Figure 10 As further shown, in some aspects, process 1000 may include: adjusting at least one of the timing of the TDRA for the second downlink communication or the timing of the first uplink feedback communication based at least in part on determining that there is a conflict between the timing of the first uplink feedback communication and the TDRA for the second downlink communication (box 1030). For example, the UE (e.g., using in Figure 13 The adjustment component 1310 described herein can adjust at least one of the timing of the TDRA for the second downlink communication or the timing of the first uplink feedback communication, as described above, based at least in part on the determination that there is a conflict between the timing of the first uplink feedback communication and the TDRA for the second downlink communication.

[0124] Process 1000 may include additional aspects, such as any single aspect or any combination thereof described below and / or in conjunction with one or more other aspects described elsewhere herein.

[0130] In the sixth aspect, either alone or in combination with the fifth aspect, the downlink-to-uplink handover gap is at least partially based on the UE's capabilities, and the process 1000 includes: sending an indication of the UE's capabilities to the base station; and receiving the configuration of the downlink-to-uplink handover gap from the base station.

[0131] In the seventh aspect, either alone or in combination with one or more of the fifth to sixth aspects, the gap also includes a fourth subset of symbols in the TDRA for second downlink communication, following the first subset of symbols.

[0132] In the eighth aspect, either alone or in combination with one or more of the fifth to sixth aspects, the gap also includes a fourth subset of symbols following the first subset of symbols to provide an uplink-to-downlink switching gap, and the adjusted TDRA also includes a fifth subset of symbols following the fourth subset of symbols in the TDRA for second downlink communication.

[0134] In the tenth aspect, either alone or in combination with the eighth aspect, process 1000 includes: receiving a first transmission of the second downlink communication in a third symbol subset; and receiving a second transmission of the second downlink communication in a fifth symbol subset.

[0135] In the eleventh aspect, either alone or in combination with the tenth aspect, the third subset of symbols comprises two or more symbols, and the fifth subset of symbols comprises two or more symbols.

[0136] In the twelfth aspect, adjusting at least one of the timing of the TDRA for the second downlink communication or the timing of the first uplink feedback communication, either alone or in combination with one or more of the first and second aspects, includes: adjusting the timing of the first uplink feedback communication from a first subset of symbols in the TDRA for the second downlink communication to a second subset of symbols at the end of the TDRA for the second downlink communication; and adjusting the TDRA for the second downlink communication to determine an adjusted TDRA excluding the second subset of symbols at the end of the TDRA for the second downlink communication.

[0137] In the thirteenth aspect, alone or in combination with the twelfth aspect, the second subset of symbols includes one or more symbols for transmitting the first uplink feedback communication and a downlink-to-uplink handover gap preceding the one or more symbols for transmitting the first uplink feedback communication, and the adjusted TDRA includes the symbols in the TDRA for the second downlink communication preceding the downlink-to-uplink handover gap.

[0138] Although Figure 10 An example box of process 1000 is shown, but in some aspects, process 1000 may include... Figure 10 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 1000 may be executed in parallel.

[0139] Figure 11 This is a diagram illustrating, for example, an example process 1100 performed by a base station according to this disclosure. Example process 1100 is an example in which a base station (e.g., base station 110) performs operations associated with joint HARQ timing and SLIV design for multi-PDSCH permission.

[0140] like Figure 11 As shown, in some aspects, process 1100 may include: sending permission to the UE to schedule multiple downlink communications, wherein the permission includes an SLIV indicating a corresponding TDRA for the multiple downlink communications and a feedback timing indicator (block 1110) indicating the timing of uplink feedback communications for the multiple downlink communications. For example, a base station (e.g., using in Figure 14 The transmitting component 1404 described herein can transmit permission to the UE to schedule multiple downlink communications, wherein the permission includes an SLIV indicating the TDRA for each of the multiple downlink communications and a feedback timing indicator indicating the timing of uplink feedback communications for the multiple downlink communications, as described above.

[0141] like Figure 11As further shown, in some aspects, process 1100 may include: determining, at least in part, based on SLIV and a feedback timing indicator, that there is a conflict between the timing of a first uplink feedback communication for at least one first downlink communication in a plurality of downlink communications and a TDRA for a second downlink communication in a plurality of downlink communications (box 1120). For example, a base station (e.g., using in Figure 14 The determining component 1408 described herein can determine, at least in part, a conflict between the timing of a first uplink feedback communication for at least one first downlink communication in a plurality of downlink communications and the TDRA for a second downlink communication in a plurality of downlink communications, as described above, based on the SLIV and the feedback timing indicator.

[0142] like Figure 11 As further shown, in some aspects, process 1100 may include: transmitting second downlink communication to the UE in an adjusted TDRA (block 1130) based at least in part on determining that there is a conflict between the timing of the first uplink feedback communication and the TDRA used for the second downlink communication. For example, a base station (e.g., using...) Figure 14 The transmitting component 1404 described herein may transmit the second downlink communication to the UE in an adjusted TDRA, as described above, based at least in part on the determination that there is a conflict between the timing of the first uplink feedback communication and the TDRA used for the second downlink communication.

[0143] Process 1100 may include additional aspects, such as any single aspect or any combination thereof described below and / or in conjunction with one or more other aspects described elsewhere herein.

[0144] In the first aspect, the downlink communication is PDSCH, which is permitted to be included in the downlink control information, and the feedback timing indicator indicates the time offset between the downlink communication in the plurality of downlink communications and the PUCCH resource used for uplink feedback communication.

[0145] In the second aspect, either alone or in combination with the first aspect, the TDRA for the second downlink communication is adjusted at least in part based on the timing of the first uplink feedback communication to determine the adjusted TDRA for the second downlink communication and the gap for the first uplink feedback communication.

[0146] In the third aspect, either alone or in combination with the second aspect, process 1100 includes: receiving first uplink feedback communication during the gap.

[0147] In the fourth aspect, either alone or in combination with one or more of the second and third aspects, the gap includes a first subset of symbols for transmitting the first uplink feedback communication and a second subset of symbols preceding the first subset of symbols to provide a downlink-to-uplink handover gap, and the adjusted TDRA includes a third subset of symbols preceding the second subset of symbols in the TDRA for the second downlink communication.

[0148] In the fifth aspect, either alone or in combination with the fourth aspect, process 1100 includes: receiving an indication of the capabilities of the UE from the UE; determining a downlink-to-uplink handover gap based at least in part on the capabilities of the UE; and sending a configuration of the downlink-to-uplink handover gap to the UE.

[0149] In the sixth aspect, either alone or in combination with one or more of the fourth to fifth aspects, the gap also includes the fourth subset of symbols in the TDRA for second downlink communication, following the first subset of symbols.

[0150] In the seventh aspect, either alone or in combination with one or more of the fourth to fifth aspects, the gap also includes a fourth subset of symbols following the first subset of symbols to provide an uplink-to-downlink switching gap, and the adjusted TDRA also includes a fifth subset of symbols following the fourth subset of symbols in the TDRA for second downlink communication.

[0151] In the eighth aspect, either alone or in combination with the seventh aspect, process 1100 includes: receiving an indication of the capabilities of the UE from the UE; determining an uplink-to-downlink handover gap based at least in part on the capabilities of the UE; and sending a configuration of the uplink-to-downlink handover gap to the UE.

[0152] In the ninth aspect, transmitting the second downlink communication in the adjusted TDRA, either alone or in combination with one or more aspects of the seventh to eighth aspects, includes: a first transmission of transmitting the second downlink communication to the UE in the third symbol subset; and a second transmission of transmitting the second downlink communication to the UE in the fifth symbol subset.

[0153] In the tenth aspect, either alone or in combination with the first aspect, the timing of the first uplink feedback communication is adjusted from a first subset of symbols in the TDRA for the second downlink communication to a second subset of symbols at the end of the TDRA for the second downlink communication, and the adjusted TDRA excludes the second subset of symbols at the end of the TDRA for the second downlink communication.

[0154] In the eleventh aspect, alone or in combination with the tenth aspect, the second subset of symbols includes one or more symbols for transmitting the first uplink feedback communication and a downlink-to-uplink handover gap preceding one or more symbols for transmitting the first uplink feedback communication, and the adjusted TDRA includes symbols in the TDRA for the second downlink communication preceding the downlink-to-uplink handover gap.

[0155] Although Figure 11 An example box of process 1100 is shown, but in some aspects, process 1100 may include... Figure 11 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 1100 may be executed in parallel.

[0156] Figure 12 This is a diagram illustrating an example process 1200 performed by a base station, for example, according to this disclosure. Example process 1200 is an example in which a base station (e.g., base station 110) performs operations associated with joint HARQ timing and SLIV design for multi-PDSCH permission.

[0157] like Figure 12 As shown, in some aspects, process 1200 may include: determining an SLIV to configure a TDRA for transmitting multiple downlink communications in corresponding time slots across multiple time slots, wherein the TDRA leaves a gap comprising one or more symbols at the end of each time slot across the multiple time slots (box 1210). For example, a base station (e.g., using...) Figure 14 The determining component 1408 described herein can determine the SLIV to configure a TDRA for transmitting multiple downlink communications in corresponding time slots in multiple time slots, wherein the TDRA leaves a gap including one or more symbols at the end of each time slot in the multiple time slots, as described above.

[0158] like Figure 12 As further shown, in some aspects, process 1200 may include: determining a feedback offset timing indicator to configure uplink feedback communication for one or more downlink communications among a plurality of downlink communications to be scheduled in a gap at the end of a time slot in a plurality of time slots (box 1220). For example, a base station (e.g., using in Figure 14 The determining component 1408 described herein can determine a feedback offset timing indicator to configure the corresponding uplink feedback communication for each downlink communication in a plurality of downlink communications to be scheduled in the gap at the end of the time slot in a plurality of time slots, as described above.

[0159] like Figure 12As further shown, in some aspects, process 1200 may include: sending permission to the UE to schedule multiple downlink communications, wherein the permission includes an SLIV and a feedback offset timing indicator (box 1230). For example, a base station (e.g., using...) Figure 14 The transmitting component 1404 described herein can send permission to the UE to schedule multiple downlink communications, wherein the permission includes SLIV and feedback offset timing indicator, as described above.

[0160] Process 1200 may include additional aspects, such as any single aspect or any combination thereof described below and / or in conjunction with one or more other aspects described elsewhere herein.

[0161] In the first aspect, one or more symbols at the end of each time slot include one or more symbols for transmitting uplink feedback communication and a downlink-to-uplink handover gap preceding one or more symbols for transmitting uplink feedback communication.

[0162] In the second aspect, either alone or in combination with the first aspect, process 1200 includes: transmitting multiple downlink communications to the UE in corresponding time slots of multiple time slots, at least in part based on a TDRA for multiple downlink communications; and receiving, at least in part based on a feedback offset timing indicator, a corresponding uplink feedback communication for a downlink communication from the UE in a gap at the end of a subsequent time slot of the corresponding time slot in which the multiple downlink communications are transmitted.

[0163] Although Figure 12 An example box of process 1200 is shown, but in some aspects, process 1200 may include... Figure 12 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 1200 may be executed in parallel.

[0164] Figure 13 This is a block diagram of an example device 1300 for wireless communication. Device 1300 may be a UE, or a UE may include device 1300. In some aspects, device 1300 includes a receiving component 1302 and a transmitting component 1304, which can communicate with each other (e.g., via one or more buses and / or one or more other components). As shown, device 1300 can use the receiving component 1302 and the transmitting component 1304 to communicate with another device 1306 (such as a UE, a base station, or another wireless communication device). As further shown, device 1300 may include one or more of a determining component 1308 or an adjusting component 1310, etc.
