[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 982,424, filed on February 27, 2020, entitled “DETERMINING TIME DOMAIN RESOURCES FOR UPLINK CANCELLATION,” and U.S. Non-Provisional Patent Application No. 17 / 181,188, filed on February 22, 2021, entitled “DETERMINING TIME DOMAIN RESOURCES FOR UPLINK CANCELLATION,” which are expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for determining time domain resources for uplink cancellation. Background Art

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

[0005] A wireless communication network may include multiple base stations (BSs) that may support communication for multiple user equipment (UEs). User equipment (UEs) may communicate with a base station (BS) via a downlink and an uplink. 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 head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] To provide a common protocol that enables diverse user devices to communicate at the city, national, regional, and even global levels, these multiple access technologies have been adopted in various telecommunications standards. New Radio (NR), also known as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR aims to better support mobile broadband internet access by improving spectral efficiency, reducing costs, improving services, leveraging new spectrum, and integrating better with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), while also supporting beamforming, multiple-input, multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunications standards that employ them. Summary of the Invention

[0026] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be exhaustive and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of the present disclosure is intended to cover any aspect of the present disclosure, whether independent of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice a method. In addition, the scope of the present disclosure is intended to cover such a device or method, which uses other structures, functions, or structures and functions in addition to or different from the various aspects of the present disclosure set forth herein to practice. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0027] Several aspects of telecommunications systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and design constraints imposed on the overall system.

[0028] Figure 1 is a diagram illustrating a wireless network 100 in which aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or New Radio (NR) network. The wireless network 100 may include multiple BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage to a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving that coverage area, depending on the context in which the term is used.

[0029] A BS may provide communication coverage to a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in FIG, BS 110a may be a macro BS for macrocell 102a, BS 110b may be a pico BS for picocell 102b, and BS 110c may be a femto BS for femtocell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB," "base station," "NR BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0030] In some aspects, the cells may not necessarily be fixed, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections, virtual networks, and / or using any suitable transport network).

[0031] 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 send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0032] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, and relay BSs. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a higher transmit power level (e.g., 5 to 40 watts), while a pico BS, femto BS, and relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0033] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0034] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smart notebook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband), smart jewelry (e.g., a smart ring, a smart bracelet), an entertainment device (e.g., a music or video device or satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0035] Some UEs may 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, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included within a housing that houses components of UE 120 (such as a processor component, a memory component, etc.). In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, electrically coupled, or similar operations.

[0036] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0037] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communicating with each other). For example, the UEs 120 can communicate using point-to-point (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In such cases, the UEs 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0038] As mentioned above, providing Figure 1 As an example. Other examples may differ from the Figure 1 The content described.

[0039] Figure 2 A base station 110 and a UE 120 (which may be Figure 1 1. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T ≥ 1 and R ≥ 1.

[0040] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI) and control information (e.g., CQI requests, grants, upper layer signaling, etc.) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively. According to various aspects described in more detail below, position coding may be utilized to generate synchronization signals to convey additional information.

[0041] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0042] On the uplink, at the UE 120, a transmit processor 264 may receive and process data and control information (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.) from a data source 262 from the controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 (if applicable), then further processed by the modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antennas 234, processed by the demodulators 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0043] As described in more detail elsewhere herein, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with determining time domain resources for uplink cancellation. Figure 2 Any other component of the may perform or direct e.g. Figure 5 The process of 500 Figure 6 600 and / or other processes described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, interpretation, and / or the like) by one or more processors of base station 110 and / or UE 120, may perform or direct, for example, Figure 5 The process of 500 Figure 6 The process 600 of , and / or other processes described herein, may include operations. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, interpreting instructions, etc. The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0044] In some aspects, the UE 120 may include means for determining an offset value to be used to determine a reference uplink resource associated with an uplink cancellation indication; means for receiving an uplink cancellation indication; and means for canceling uplink communications in a set of reference uplink resources, wherein the set of reference uplink resources is determined at least in part based on the offset value and a time domain resource in which the uplink cancellation indication is received. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0045] In some aspects, the base station 110 may include a component for sending a configuration message to the UE, the configuration message indicating an offset value to be used to indicate a reference uplink resource associated with the uplink cancellation indication; a component for identifying one or more time domain resources in which the UE's uplink communication is to be canceled; and a component for sending an uplink cancellation indication to the UE indicating a reference uplink resource set, the reference uplink resource set including one or more time domain resources in which the uplink communication is to be canceled, wherein the reference uplink resource set is indicated based at least in part on the offset value and the time domain resource in which the uplink cancellation indication is sent; and / or similar components. In some aspects, such components may include a combination of Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0046] As mentioned above, Figure 2 Provided as an example. Other examples may differ from the Figure 2 An example of description.

[0047] Figure 3 is a diagram illustrating an example 300 of determining time domain resources for uplink cancellation without considering timing advance according to the present disclosure.

[0048] An uplink cancellation indication (ULCI) 305, sometimes referred to as an uplink preemption indication (ULPI), can be used to cancel or preempt one or more uplink communications of a UE. For example, a base station may schedule low-priority uplink communications (e.g., enhanced mobile broadband (eMBB) communications) for a UE and may later need to schedule high-priority communications (e.g., ultra-reliable low-latency communications (URLLC)) for the UE or another UE. In this case, the base station can cancel the low-priority uplink communications scheduled for the UE (or a group of low-priority uplink communications scheduled for the group of UEs) by sending ULCI 305 to the UE (or a group of UEs). Alternatively, the base station can cancel a portion of the low-priority uplink communications (e.g., a portion that overlaps or conflicts with the high-priority communications).

[0049] The UE may receive the ULCI 305 before the scheduled low-priority communication and may cancel all or part of the scheduled low-priority communication to prevent interference with the high-priority communication. Thus, the ULCI 305 enables the base station to schedule the high-priority communication on the resources previously allocated to the low-priority communication and avoid interference with the high-priority communication caused by the low-priority communication.

[0050] In some cases, the base station may send the ULCI 305 using downlink control information (DCI) (e.g., a physical downlink control channel (PDCCH) communication) having a specific format, such as DCI format 2_4. The ULCI 305 may be used to cancel one or more uplink communications previously scheduled for the UE (e.g., on the serving cell via which the ULCI is received), such as a physical uplink shared channel (PUSCH) communication (e.g., an uplink data communication), a sounding reference signal (or another type of uplink reference signal), etc. The ULCI 305 may (e.g., explicitly or implicitly) indicate a reference uplink resource set 310 in which the uplink communication is to be canceled (shown as T CI Symbol). The reference uplink resource set 310 may include one or more time domain resources. In some cases, the reference uplink resource set 310 is referred to as a time domain resource associated with a cancellation indication and may include a set of time domain resources denoted as T CI Multiple symbols (e.g., orthogonal frequency division multiplexing (OFDM) symbols).

[0051] The UE may receive the ULCI 305 and may determine the reference uplink resource set 310 based at least in part on the time domain resource in which the ULCI 305 is received and the UE's uplink processing time 315. For example, the initial symbol (e.g., the first symbol or the earliest symbol in time) of the reference uplink resource set 310 may be T 1 that occurs after the last symbol of the ULCI 305. proc，2 The first symbol of 10 symbols (e.g., the end of PDCCH reception from a DCI with format 2_4). Here, T proc，2 T represents the uplink processing time 315 of the UE (e.g., PUSCH preparation process time), such as the time required for the UE to detect the ULCI 305 and cancel the corresponding uplink communication (e.g., the uplink communication included in the reference uplink resource set 310). As a more specific example, T proc，2 The PUSCH processing preparation time may be represented as corresponding to the UE's PUSCH processing capability of 2. In some aspects, the UE may indicate the uplink processing time 315 (eg, corresponding to a PUSCH processing capability of 2) to the base station in a UE capability report.

[0052] However, due to propagation delays in communications between the base station and the UE, there may be timing differences between downlink communications and uplink communications. For example, the internal timing maintained by the UE (e.g., symbol position, symbol boundary, slot position, slot boundary, etc.) may not be synchronized with the internal timing maintained by the base station. The timing difference may depend on the position of the UE in the cell (e.g., relative to the base station), which may result in different propagation delays. In order to compensate for propagation delays and lack of synchronization, the UE may adjust or advance the transmit time that the UE uses to send uplink communications. For example, the base station may send a timing advance (TA) command to the UE, and the UE may adjust (e.g., advance) the transmit time of the uplink communication according to the TA command (e.g., according to the TA value indicated in the TA command). This enables the base station to receive uplink communications from the UE according to the internal timing maintained by the base station.

[0053] As shown at 320, when the UE adjusts the transmission time of an uplink communication (e.g., included in the reference uplink communication set 310) in accordance with the TA command, the uplink communication may occur earlier in time than if the UE were to use internal timing previously stored by the UE before receiving the TA command. As a result, as shown at 325, the time gap between the UE's reception of the ULCI 305 and the scheduled transmission of the uplink communication may be reduced. This may result in the time gap being less than the UE's uplink processing time for detecting the ULCI 305 and canceling the uplink communication (e.g., may be less than T proc，2 As a result, the UE may not be able to cancel the uplink communication (e.g., on one or more symbols in the beginning portion of the reference uplink resource set 310) and may send the uplink communication. This may interfere with higher priority uplink communications (e.g., URLLC communications), thereby reducing the reliability of the URLLC communications and increasing latency.

[0054] Some techniques and apparatuses described herein enable a UE and a base station to take the TA value into account when canceling uplink communications. For example, a base station may configure an offset value (e.g., d) that may be added to the T proc，2 The value of TA is used so that the UE can determine the initial symbol of the reference uplink resource set 310. As a result, the UE can cancel the uplink communication that is advanced in time because the start of the reference uplink resource set 310 is offset in time by the offset value, which can be a number of symbols larger than the effect of the TA value. In this way, interference with high-priority uplink communications (e.g., URLLC communications) can be avoided, thereby improving the reliability of URLLC communications and reducing latency.

[0055] As mentioned above, Figure 3 Provided as an example. Other examples may differ from the Figure 3 The content described.

[0056] Figure 4 is a diagram illustrating an example 400 of determining time domain resources for uplink cancellation while considering timing advance according to the present disclosure.

[0057] like Figure 4 As shown, UE 120 may determine an offset value 405 (shown as d). UE 120 may use offset value 405 to determine a reference uplink resource 410 associated with a ULCI (shown as ULCI 415). In some aspects, UE 120 may receive an indication of offset value 405 from base station 110. For example, UE 120 may receive the indication of offset value 405 in a configuration message, such as a radio resource control (RRC) message (e.g., an RRC configuration message or an RRC reconfiguration message). Additionally or alternatively, UE 120 may determine offset value 405 based at least in part on a timing advance value. In some aspects, UE 120 may receive the timing advance value from base station 110. In some aspects, UE 120 may determine offset value 405 to be a value greater than the timing advance value (e.g., may set offset value 405 to a value greater than the timing advance value). Thus, UE 120 may determine offset value 405 based at least in part on the indication from base station 110.

[0058] In some aspects, the offset value 405 is indicated using a value representing a plurality of symbols. In some aspects, the symbol length of each symbol in the plurality of symbols is determined by the UE 120 based at least in part on the symbol length of downlink symbols in the downlink bandwidth part (BWP) over which the ULCI 415 is received. For example, in a mixed digital scenario, downlink symbols and uplink symbols may have different symbol lengths. In this case, the UE 120 may use the symbol length of the downlink symbols to determine the symbol length of the uplink symbols indicated by the offset value 405 to reduce or avoid ambiguity between the UE 120 and the base station 110.

[0059] In some aspects, the offset value 405 is greater than or equal to a maximum timing advance value associated with the UE 120. This can ensure that the UE 120 can perform uplink cancellation after receiving the ULCI 415, regardless of the TA and / or propagation delay associated with the UE 120. In some aspects, the maximum timing advance value is based at least in part on the size of the serving cell of the UE 120 (e.g., a larger maximum TA value for a larger sized cell and a smaller maximum TA value for a smaller sized cell). Additionally or alternatively, the offset value 405 can be greater than or equal to a maximum timing advance value associated with a group of UEs 120 (including the UE 120) to which the ULCI 415 is transmitted. For example, the base station 110 can use group-common DCI signaling to perform uplink cancellation for a group of UEs 120. In this case, using an offset value 405 that is greater than or equal to the maximum timing advance value associated with the group of UEs 120 may ensure that all UEs 120 in the group are able to perform uplink cancellation after receiving the ULCI 415, regardless of the TA and / or propagation delay associated with the UEs 120 in the group.

[0060] like Figure 4 As further shown, the base station 110 may transmit and the UE 120 may receive a ULCI 415. In some aspects, the ULCI 415 may be transmitted or included in a DCI message having a specific DCI format, such as DCI format 2_4. The base station 110 may identify one or more time domain resources in which one or more uplink communications of the UE 120 are to be canceled, and may transmit the ULCI 415 to cancel the one or more uplink communications.

[0061] like Figure 4 As further shown, the UE 120 may determine a reference uplink resource set 410 based at least in part on the offset value 405 and the time domain resource in which the ULCI 415 is received. As further shown, the UE 120 may determine the reference uplink resource set 410 based at least in part on the time domain resource in which the ULCI 415 is received, the offset value 405, and an uplink processing time 420 associated with the UE 120 (e.g., a PUSCH preparation time, a PUSCH preparation time, or a PUSCH preparation procedure time). As an example, the uplink processing time 420 is Figure 4 Indicated as T proc，2 , which may correspond to the time required for the UE 120 to detect the ULCI 415 and cancel subsequent uplink communications. In some aspects, as shown, the reference uplink resource set 410 (shown as T CIsymbols) is offset from the last symbol (e.g., the most recently occurring symbol) of the ULCI 415 by an amount of symbols equal to or based at least in part on the uplink processing time 420 of the UE 120 plus the offset value 405.

[0062] As indicated by reference numeral 425, in some aspects, the UE 120 may determine the reference uplink resource set 410 based at least in part on the uplink processing time 420 of the UE 120, the offset value 405, and the logical time or logical symbol index of the PDCCH communication (e.g., DCI format 2_4) carrying the ULCI 415. For example, the initial symbol of the reference uplink resource set 410 may be offset from the logical symbol index of the last symbol of the ULCI 415 by a number of symbols equal to the uplink processing time 420 of the UE 120 plus the offset value 405. As a more specific example, and as shown in FIG. Figure 4 As shown, if the uplink processing time 420 of the UE 120 is 5 symbols and the offset value 405 is 2 symbols, and if the symbol index of the last symbol of the ULCI 415 is 2, then the symbol index of the initial symbol of the reference uplink resource set 410 is 10 (because 5+2=7 symbols occur between the end of the ULCI 415 and the beginning of the reference uplink resource set 410). In this example, the propagation delay is equal to 1 symbol and the TA is equal to 2 symbols, so the actual time difference between the end of the ULCI 415 and the beginning of the reference uplink resource set is 5 symbols, which is equal to the uplink processing time 420 and is sufficient to cause the UE 120 to cancel the uplink communication(s) in the reference uplink resource set 410.

[0063] Based at least in part on determining the reference uplink resource set 410, the UE 120 may cancel one or more uplink communications in the reference uplink resource set 410 (e.g., one or more uplink communications scheduled to occur in the reference uplink resource set 410). For example, the UE 120 may cancel lower priority uplink communications based at least in part on higher priority uplink communications (e.g., associated with one or more other UEs 120) scheduled in the reference uplink resource set 410. The uplink communications to be canceled may include, for example, PUSCH communications or sounding reference signals (SRS).

[0064] Using the techniques described herein, UE 120 can cancel uplink communications that are early in time because the start of the reference uplink resource set 410 is offset in time by the offset value 405. In this way, interference with high-priority uplink communications (e.g., URLLC communications) can be avoided, thereby improving the reliability of URLLC communications and reducing latency.

[0065] As mentioned above, Figure 4 are provided as examples. Other examples may differ from those described in Figure 4 An example of description.

[0066] Figure 5 is a diagram illustrating an example process 500, performed, for example, by a UE, according to the present disclosure. Example process 500 is an example in which a UE (eg, UE 120, etc.) performs operations associated with determining time domain resources for uplink cancellation.

[0067] like Figure 5 As shown, in some aspects, process 500 may include determining an offset value to be used to determine a reference uplink resource associated with the uplink cancellation indication (block 510). For example, as described above, the UE (e.g., using receive processor 258, controller / processor 280, memory 282, etc.) may determine an offset value to be used to determine a reference uplink resource associated with the uplink cancellation indication.

[0068] like Figure 5 As further shown, in some aspects, process 500 may include receiving an uplink cancellation indication (block 520). For example, as described above, the UE (e.g., using receive processor 258, controller / processor 280, memory 282, etc.) may receive the uplink cancellation indication.

[0069] like Figure 5 As further shown, in some aspects, process 500 may include canceling uplink communications in a reference set of uplink resources, where the reference set of uplink resources is determined at least in part based on the offset value and the time domain resource in which the uplink cancellation indication is received (block 530). For example, as described above, the UE (e.g., using transmit processor 264, controller / processor 280, memory 282, etc.) may cancel uplink communications in the reference set of uplink resources. In some aspects, the reference set of uplink resources is determined at least in part based on the offset value and the time domain resource in which the uplink cancellation indication is received.

In some embodiments, the process 500 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in FIG. Additionally or alternatively, two or more blocks in process 500 may be performed in parallel.

[0090] Figure 6 is a diagram illustrating an example process 600, performed, for example, by a base station, in accordance with the present disclosure. Example process 600 is an example in which a base station (eg, base station 110, etc.) performs operations associated with determining time domain resources for uplink cancellation.

[0091] like Figure 6 As shown, in some aspects, process 600 may include sending a configuration message to the UE indicating an offset value to be used to indicate a reference uplink resource associated with the uplink cancellation indication (block 610).
