Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to wireless communication methods, terminal devices, and network devices. Background Technology

[0002] For Time Division Duplexing (TDD) spectrum, the transmission time slots for repetition of the Physical Uplink Control Channel (PUCCH) are determined according to the time slot format configuration, and N time slots that meet the conditions are selected, where N is configured by the network.

[0003] To ensure PUCCH transmission reliability, relevant protocols stipulate that N time slots must be found to meet certain conditions for PUCCH repetition. This means that PUCCH transmission delays may be relatively long. For example, the impact of PUCCH transmission delays is negligible for Enhanced Mobile Broadband (eMBB) services, but for Ultra-Reliable and Low-Latency Communication (URLLC) services, which are latency-sensitive, PUCCH transmission delays have two main effects. First, the feedback delay of Hybrid Automatic Repeat Request-ACK (HARQ-ACK) exceeds the service delay, rendering HARQ-ACK useless information because it is no longer possible to determine whether to trigger a retransmission based on HARQ-ACK information. Second, due to the lack of HARQ-ACK feedback, the HARQ process corresponding to downlink data cannot be released, limiting the transmission opportunities of other data. Summary of the Invention

[0039] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0040] Figure 1 This is a schematic diagram of a communication system 100 according to an embodiment of this application.

[0041] like Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0042] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto. That is to say, the technical solutions of the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems, etc.

[0043] exist Figure 1 In the communication system 100 shown, network device 120 may be an access network device that communicates with terminal device 110. The access network device can provide communication coverage for a specific geographical area and can communicate with terminal device 110 (e.g., UE) located within that coverage area.

[0044] Network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, a Next Generation Radio Access Network (NG RAN) device, a base station (gNB) in an NR system, a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, access point, vehicle-mounted device, wearable device, hub, switch, bridge, router, or network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0045] Terminal device 110 can be any terminal device, including but not limited to terminal devices that are connected to network device 120 or other terminal devices via wired or wireless connections.

[0046] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The access terminal may be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, IoT device, satellite handheld terminal, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal device in a 5G network, or terminal device in a future evolved network, etc.

[0047] Terminal device 110 can be used for device-to-device (D2D) communication.

[0048] The wireless communication system 100 may further include a core network device 130 that communicates with the base station. This core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device for an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions of both SMF and PGW-C. During network evolution, the aforementioned core network device may also be called by other names, or new network entities may be formed by dividing the core network functions; this embodiment does not limit this.

[0049] The various functional units in the communication system 100 can also establish connections and communicate with each other through the next generation (NG) interface.

[0050] For example, terminal devices establish air interface connections with access network devices through the NR interface for transmitting user plane data and control plane signaling; terminal devices can establish control plane signaling connections with the AMF through NG interface 1 (N1); access network devices, such as next-generation radio access base stations (gNB), can establish user plane data connections with the UPF through NG interface 3 (N3); access network devices can establish control plane signaling connections with the AMF through NG interface 2 (N2); the UPF can establish control plane signaling connections with the SMF through NG interface 4 (N4); the UPF can interact with the data network for user plane data through NG interface 6 (N6); the AMF can establish control plane signaling connections with the SMF through NG interface 11 (N11); and the SMF can establish control plane signaling connections with the PCF through NG interface 7 (N7).

[0051] Figure 1An exemplary embodiment shows a base station, a core network device, and two terminal devices. Optionally, the wireless communication system 100 may include multiple base station devices, and each base station may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0052] It should be understood that any device with communication functionality in the network / system described in this application embodiment can be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 120 and a terminal device 110 with communication functions. The network device 120 and the terminal device 110 may be the devices described above, which will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as network controllers, mobility management entities and other network entities. This application embodiment does not limit this.

[0053] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0054] Furthermore, the term "instruction" used in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of an association. For example, A instructing B can mean that A directly instructs B, such as B being able to obtain information through A; it can also mean that A indirectly instructs B, such as A instructing C, so B can obtain information through C; or it can mean that there is an association between A and B.

[0055] Furthermore, the term "correspondence" mentioned in the embodiments of this application can indicate a direct or indirect correspondence between two things, or an association between them, or a relationship of instruction and being instructed, configuration and being configured, etc. The "predefined" or "predefined rule" mentioned in the embodiments of this application can be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in the device (e.g., including terminal devices and network devices). This application does not limit the specific implementation method. For example, predefined can refer to what is defined in a protocol. It should also be understood that in the embodiments of this application, the "protocol" can refer to standard protocols in the field of communication, such as the LTE protocol, the NR protocol, and related protocols applied to future communication systems. This application does not limit this. In the embodiments of this application, the terms "downlink" and "uplink" are used to indicate the transmission direction of signals or data. "Downlink" indicates that the transmission direction of signals or data is a first direction from the site to the user equipment in the cell, and "uplink" indicates that the transmission direction of signals or data is a second direction from the user equipment in the cell to the site. For example, "downlink signal" indicates that the transmission direction of the signal is the first direction.

[0056] NR uses a frame length of 10ms, and one frame contains 10 subframes. Five subframes make up a half frame, and subframes numbered 0-4 and subframes numbered 5-9 are in different half frames.

[0057] The basic frame structure of New Radio (NR) is based on time slots. In the standard Cyclic Prefix (CP) configuration, each time slot contains 14 symbols. In the extended CP configuration, each time slot contains 12 symbols. The symbols in each time slot can be divided into three categories: downlink symbols, uplink symbols, and flexible symbols. Depending on the actual scheduling by the base station, flexible symbols can be used to transmit either downlink or uplink data; that is, the transmission direction of the symbol is not fixed.

[0058] The NR frame structure configuration employs a flexible approach combining semi-static configuration via Radio Resource Control (RRC) signaling and dynamic configuration via Downlink Control Information (DCI). RRC configuration supports both cell-specific and UE-specific RRC configuration methods. DCI configuration supports both direct indication via slot format indication (SFI) and determination via DCI scheduling.

[0059] 1. Semi-static frame structure configuration.

[0060] The NR system is based on a periodically configured frame structure, with only one downlink-to-uplink transition point in each period. This ensures the continuity of downlink and uplink resources within each period. The frame structure period in Rel-15 can be 0.5ms, 0.625ms, 1ms, 1.25ms, 2ms, 2.5ms, 5ms, or 10ms.

[0061] 2. Dynamic DCI configuration.

[0062] Dynamic DCI configuration of the frame structure can be achieved by instructing SFI using DCI format 2_0, or by scheduling uplink or downlink data transmission using DCI format 0_0 / 0_1 / 0_2 / 1_0 / 1_1 / 1_2. While scheduling data does not directly change the frame structure, DCI scheduling implicitly indicates the transmission direction of the scheduled symbols.

[0063] Typically, for Time Division Duplex (TDD) spectrum, the time slots for repetition of the Physical Uplink Control Channel (PUCCH) are determined based on a semi-static configuration of uplink and flexible symbols, resulting in N time slots that meet certain conditions, where N is configured by the network. Specific conditions can be:

[0064] The start symbol for PUCCH is a flexible symbol other than the uplink symbol or the SS / PBCH symbol;

[0065] The number of consecutive uplink symbols or flexible symbols other than SS / PBCH symbols, starting from the start symbol of PUCCH, is greater than or equal to the number of symbols in PUCCH.

[0066] Figure 2 This is a schematic diagram illustrating the principle of the delay in PUCCH repetition provided in the embodiments of this application.

[0067] like Figure 2 As shown, based on the timing relationship between PDSCH and PUCCH (which can be determined through the DCI indication of PDSCH scheduling or semi-static configuration), the time slots for PUCCH repetition 1 and PUCCH repetition 2 are determined to be the 3rd and 4th time slots, respectively. However, the symbols in the 3rd and 4th time slots are all downlink symbols, meaning they are unusable time slots. Therefore, the search continues until the 8th and 9th time slots, where the symbols are all uplink symbols, allowing PUCCH transmission. Based on this, the 8th and 9th time slots can be identified as the usable time slots for PUCCH repetition 1 and PUCCH repetition 2, respectively.

[0068] As shown above, to ensure the reliability of PUCCH transmission, N time slots that meet the conditions must be found for PUCCH repetition. This means that a relatively long PUCCH transmission delay may occur. For example, for Enhanced Mobile Broadband (eMBB) services, the impact of PUCCH transmission delay is negligible. However, for Ultra-Reliable and Low-Latency Communication (URLLC) services, which are latency-sensitive, PUCCH transmission delay has two main effects. First, the feedback delay of Hybrid Automatic Repeat Request-ACK (HARQ-ACK) exceeds the service delay, rendering HARQ-ACK useless information because it is no longer possible to determine whether to trigger a retransmission based on HARQ-ACK information. Second, due to the lack of HARQ-ACK feedback, the HARQ process corresponding to downlink data cannot be released, thus limiting the transmission opportunities of other data.

[0069] Based on this, this application provides a wireless communication method that introduces a maximum threshold for the delay of PUCCH repetition and determines the transmission time slot of the PUCCH repetition based on the maximum threshold. This is equivalent to constraining the transmission of the PUCCH repetition through the maximum threshold. On the one hand, it can ensure the normal transmission of the PUCCH repetition, that is, ensure that the network side can make timely decisions on whether to initiate retransmission. On the other hand, constraining the transmission of the PUCCH repetition through the maximum threshold helps to avoid the transmission of invalid information, thereby improving system efficiency.

[0070] Figure 3 A schematic flowchart of a wireless communication method 200 according to an embodiment of this application is shown, which can be executed by a terminal device. Figure 1 The terminal device shown.

[0071] like Figure 3 As shown, the method 200 may include some or all of the following:

[0072] S210, obtain the maximum threshold for the delay of physical uplink control channel (PUCCH) repetition;

[0073] S220, determine the time-domain resource unit for PUCCH repetition based on the maximum threshold.

[0074] In this embodiment, by introducing a maximum threshold for the delay of PUCCH repetition and determining the transmission time slot of PUCCH repetition based on the maximum threshold, it is equivalent to constraining the transmission of PUCCH repetition by the maximum threshold. On the one hand, it can ensure the normal transmission of PUCCH repetition, that is, ensure that the network side can make timely decisions on whether to initiate retransmission; on the other hand, constraining the transmission of PUCCH repetition by the maximum threshold helps to avoid the transmission of invalid information, thereby improving system efficiency.

[0075] In some embodiments, the interval between the location of the time-domain resource unit of the PUCCH repetition and the location of the time-domain resource unit of the downlink data (e.g., PDSCH) corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and / or the interval between the location of the time-domain resource unit of the PUCCH repetition and the location of the time-domain resource unit determined by the timing relationship of the PUCCH repetition is less than or equal to the maximum threshold.

[0076] For example, the interval between the start position of the time-domain resource unit of the PUCCH repetition and the start position of the time-domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and / or, the interval between the start position of the time-domain resource unit of the PUCCH repetition and the start position of the time-domain resource unit determined by the timing relationship of the PUCCH repetition is less than or equal to the maximum threshold. As another example, the interval between the end position of the time-domain resource unit of the PUCCH repetition and the end position of the time-domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and / or, the interval between the end position of the time-domain resource unit of the PUCCH repetition and the end position of the time-domain resource unit determined by the timing relationship of the PUCCH repetition is less than or equal to the maximum threshold. For example, the interval between the start position of the time-domain resource unit of the PUCCH repetition and the end position of the time-domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and / or, the interval between the start position of the time-domain resource unit of the PUCCH repetition and the end position of the time-domain resource unit determined by the timing relationship of the PUCCH repetition is less than or equal to the maximum threshold. For example, the interval between the end position of the time-domain resource unit of the PUCCH repetition and the start position of the time-domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and / or, the interval between the end position of the time-domain resource unit of the PUCCH repetition and the start position of the time-domain resource unit determined by the timing relationship of the PUCCH repetition is less than or equal to the maximum threshold.

[0077] In other words, the maximum threshold in this application embodiment can be used to limit the interval between the location of the time-domain resource unit of the PUCCH repetition and the location of the time-domain resource unit of the downlink data corresponding to the PUCCH repetition, or it can be used to limit the interval between the location of the time-domain resource unit of the PUCCH repetition and the location of the time-domain resource unit determined by the timing relationship of the PUCCH repetition.

[0078] It should be noted that the timing relationship in this application can refer to the timing relationship between the PDSCH and the PUCCH used for PDSCH feedback. This can be achieved through the DCI indication of the PDSCH scheduling, or through semi-static configuration.

[0079] In some embodiments, the PUCCH repetition is used to carry uplink control information (UCI); and / or, the PUCCH repetition includes a PUCCH carrying a hybrid automatic repeat request acknowledgment (HARQ-ACK); and / or, the PUCCH repetition does not include a PUCCH carrying channel state information (CSI).

[0080] In other words, the maximum threshold can be set independently for UCI. For example, only PUCCH repetition carrying HARQ-ACK is subject to a maximum threshold. Conversely, PUCCH repetition carrying CSI is not subject to a maximum threshold.

[0081] In some embodiments, S210 may include:

[0082] Receive semi-static configuration information, wherein the semi-static configuration information includes the maximum threshold;

[0083] The maximum threshold is obtained based on the semi-static configuration information.

[0084] In some embodiments, the maximum threshold is configured independently using the semi-static configuration information corresponding to the PUCCH repeat.

[0085] In some embodiments, the semi-static configuration information may be higher-level signaling.

[0086] In some embodiments, the semi-static configuration information includes at least one of the following:

[0087] Physical downlink shared channel configuration (PDSCH-Config), semi-static scheduling configuration (SPS-Config), PUCCH configuration (PUCCH-Config), and PUCCH format configuration (PUCCH-FormatConfig).

[0088] For example, PDSCH-Config, SPS-Config, PUCCH-Config, or PUCCH-FormatConfig can be configured independently for the Physical Downlink Shared Channel (PDSCH-Config), Semi-static Scheduling (SPS-Config), PUCCH-Config, or PUCCH-FormatConfig. If multiple SPS-Configs require the maximum threshold to be configured, it can be configured independently in each SPS-Config.

[0089] In some embodiments, S210 may include:

[0090] Receive indication information, the indication information being used to indicate the maximum threshold;

[0091] The maximum threshold is obtained based on the indicated information.

[0092] In some embodiments, the indication information indicates the maximum threshold by at least one of the following:

[0093] The indication field in the downlink control information (DCI) repeatedly associated with the PUCCH;

[0094] The DCI format repeatedly associated with the PUCCH;

[0095] The search space containing the DCI that is repeatedly associated with the PUCCH;

[0096] The control resource set CORESET where the DCI repeatedly associated with the PUCCH is located;

[0097] The CRC scrambling method of the DCI repeatedly associated with the PUCCH;

[0098] The RNTI used when performing CRC scrambling on the DCI repeatedly associated with the PUCCH;

[0099] The aggregation level of DCI repeatedly associated with the PUCCH; and

[0100] Priority indication in the DCI repeatedly associated with the PUCCH.

[0101] In other words, the maximum threshold can also be dynamically indicated. For example, an indication field can be added to the DCI associated with PUCCH repetition to indicate the maximum threshold, or the maximum threshold can be determined based on the format of the DCI associated with PUCCH repetition, the search space or CORESET in which the DCI associated with PUCCH repetition is located, the CRC scrambling method of the DCI associated with PUCCH repetition (e.g., the RNTI used for CRC scrambling), the aggregation level of the DCI associated with PUCCH repetition, and the priority indication in the DCI associated with PUCCH repetition. Taking the determination of the maximum threshold based on the priority indication in the DCI associated with PUCCH repetition as an example, a first priority can be predefined or configured by higher-layer network signaling to correspond to a first threshold, and a second priority can correspond to a second threshold. When the DCI received by the terminal indicates the first priority, the maximum threshold for its corresponding PUCCH repetition is determined according to the first delay threshold. When the DCI received by the terminal indicates the second priority, the maximum threshold for its corresponding PUCCH repetition is the second threshold.

[0102] In some embodiments, the indication information is used to indicate the maximum threshold among a plurality of thresholds, the plurality of threshold values ​​being configured through semi-static configuration information.

[0103] In other words, multiple thresholds can be configured semi-statically, with one of the dynamically indicated values ​​serving as the maximum threshold. In one implementation, the multiple thresholds are configured via PUCCH-Config, for example, independently for each PUCCH-Config. The multiple thresholds are determined based on the PUCCH-Config corresponding to the PUCCH repetition, which can be determined based on the priority of the corresponding DCI indication or the priority of the semi-static configuration. In another implementation, the multiple thresholds can be configured independently for PUCCH-FormatConfig (e.g., each PUCCH format or PUCCH formats 1, 3, and 4). The multiple thresholds are determined based on the PUCCH-Config corresponding to the PUCCH repetition. For example, the network side configures a threshold value of x1 for the first PUCCH format in the first PUCCH-Config and a threshold value of x2 for the second PUCCH format; and configures a threshold value of x3 for the first PUCCH format in the second PUCCH-Config and a threshold value of x4 for the second PUCCH format. The terminal determines that the PUCCH-Config corresponding to the PUCCH repetition is the first PUCCH-Config based on the priority indication (e.g., high priority) in the DCI; in addition, it determines that the format adopted by the PUCCH resource indicated in the DCI is the first PUCCH format; then the terminal can determine that the maximum threshold for PUCCH repetition corresponding to the current DCI is x1.

[0104] In some embodiments, the PUCCH repeating time-domain resource unit includes N time-domain resource units, and the first time-domain resource unit among the N time-domain resource units satisfies the maximum threshold requirement; or the PUCCH repeating time-domain resource unit includes the time-domain resource unit among the N time-domain resource units that satisfies the maximum threshold requirement; or the PUCCH repeating time-domain resource unit includes N time-domain resource units, and the last time-domain resource unit among the N time-domain resource units satisfies the maximum threshold requirement; or the PUCCH repeating is not expected to be transmitted, and any one of the N time-domain resource units does not satisfy the maximum threshold requirement.

[0105] Figures 4 to 7 This is an example of a PUCCH repeating transmission time slot provided in an embodiment of this application. The following is in conjunction with… Figures 4 to 7 Taking the time-domain resource unit as an example, the implementation of determining the time-domain resource unit of PUCCH repetition based on the maximum threshold is illustrated by way of example.

[0106] In some embodiments, the time-domain resource unit of the PUCCH repetition includes N time-domain resource units, and the first time-domain resource unit among the N time-domain resource units satisfies the requirement of the maximum threshold.

[0107] For example, such as Figure 4 As shown, the time-domain resource units determined by the timing relationship of PUCCH Repeat 1 and PUCCH Repeat 2 are the 3rd and 4th time slots, respectively. The available time-domain resource units determined by the time slot format configuration of PUCCH Repeat 1 and PUCCH Repeat 2 are the 6th and 9th time slots, respectively, with a maximum threshold of 6 time slots. Since the 6th time slot containing PUCCH Repeat 1 is earlier than the end position of the maximum threshold, that is, the 6th time slot containing PUCCH Repeat 1 meets the requirement of the maximum threshold, PUCCH Repeat 1 and PUCCH Repeat 2 can be transmitted on the 6th and 9th time slots, respectively. In other words, since the interval between PUCCH Repeat 1 and PDSCH is less than or equal to 6 time slots, that is, the 6th time slot containing PUCCH Repeat 1 meets the requirement of the maximum threshold, PUCCH Repeat 1 and PUCCH Repeat 2 can be transmitted on the 6th and 9th time slots, respectively.

[0108] In this embodiment, by ensuring that at least a portion of the PUCCH that meets the maximum threshold requirement is repeated during normal transmission, the network side can make timely decisions on whether to initiate a retransmission. Furthermore, by repeating at least a portion of the PUCCH that does not meet the maximum threshold requirement, the reliability of UCI transmission carried in the PUCCH can be guaranteed.

[0109] In some embodiments, the time-domain resource unit for PUCCH repetition includes the time-domain resource unit among N time-domain resource units that meets the requirement of the maximum threshold.

[0110] For example, such as Figure 5As shown, the time-domain resource units determined by the timing relationship of PUCCH Repeat 1 and PUCCH Repeat 2 are the 3rd and 4th time slots, respectively. The available time-domain resource units determined by the time slot format configuration of PUCCH Repeat 1 and PUCCH Repeat 2 are the 6th and 9th time slots, respectively, with a maximum threshold of 6 time slots. Since the 6th time slot containing PUCCH Repeat 1 is earlier than the end position of the maximum threshold, that is, the 6th time slot containing PUCCH Repeat 1 meets the requirement of the maximum threshold; while the 9th time slot containing PUCCH Repeat 2 is later than the end position of the maximum threshold, that is, the 9th time slot containing PUCCH Repeat 2 does not meet the requirement of the maximum threshold; therefore, PUCCH Repeat 1 can be transmitted only in the 6th time slot. In other words, since the interval between the time slot containing PUCCH Repeat 1 and PDSCH is less than or equal to 6 time slots, and the interval between the time slot containing PUCCH Repeat 2 and PDSCH is greater than 6 time slots, PUCCH Repeat 1 can be transmitted only in the 6th time slot.

[0111] In this embodiment, by ensuring that at least a portion of the PUCCH repeats that meet the maximum threshold requirement during normal transmission, the network side can make timely decisions on whether to initiate a retransmission. Furthermore, since receiving repeated PUCCHs after the maximum threshold no longer affects subsequent data retransmission decisions, by constraining at least a portion of the PUCCH repeats that do not meet the maximum threshold requirement—that is, only transmitting at least a portion of the PUCCH repeats that meet the maximum threshold requirement—invalid information transmission can be avoided, improving system efficiency.

[0112] In some embodiments, the time-domain resource unit of the PUCCH repetition includes N time-domain resource units, and the last time-domain resource unit among the N time-domain resource units satisfies the maximum threshold requirement.

[0113] For example, such as Figure 6 As shown, the time-domain resource units determined by the timing relationship of PUCCH Repeat 1 and PUCCH Repeat 2 are the 3rd and 4th time slots, respectively. The available time-domain resource units determined by the time slot format configuration of PUCCH Repeat 1 and PUCCH Repeat 2 are the 6th and 7th time slots, respectively, with a maximum threshold of 6 time slots. Since the last time slot in the 6th and 7th time slots is before the end of the maximum threshold, PUCCH Repeat 1 and PUCCH Repeat 2 can be transmitted on the 6th and 7th time slots, respectively. In other words, since the interval between the last time slot in the 6th and 7th time slots and the PDSCH is less than or equal to 6 time slots, that is, the 7th time slot where PUCCH Repeat 2 is located meets the requirement of the maximum threshold, PUCCH Repeat 1 and PUCCH Repeat 2 can be transmitted on the 6th and 7th time slots, respectively.

[0114] In this embodiment, by constraining the transmission of PUCCH repetitions by the maximum threshold, not only can timely and effective PUCCH repetitions and transmission reliability be guaranteed, thus ensuring that the network side can make timely decisions on whether to initiate retransmission, but also invalid information transmission can be avoided, thereby improving system efficiency.

[0115] In some embodiments, the PUCCH repetition is not expected to be transmitted, and any one of the N time-domain resource elements does not meet the maximum threshold requirement.

[0116] For example, such as Figure 7 As shown, the time-domain resource units determined by the timing relationship of PUCCH Repeat 1 and PUCCH Repeat 2 are the 3rd and 4th time slots, respectively. The available time-domain resource units determined by the time slot format configuration of PUCCH Repeat 1 and PUCCH Repeat 2 are the 6th and 9th time slots, respectively, with a maximum threshold of 6 time slots. Since the last time slot of the 6th and 9th time slots is after the end of the maximum threshold, the terminal device does not expect to transmit PUCCH Repeat 1 and PUCCH Repeat 2; in other words, the time slots of PUCCH Repeat 1 and PUCCH Repeat 2 are empty. In other words, since the interval between the last time slot of the 6th and 9th time slots and the PDSCH is greater than 6 time slots, the terminal device does not expect to transmit PUCCH Repeat 1 and PUCCH Repeat 2; in other words, the time slots of PUCCH Repeat 1 and PUCCH Repeat 2 are empty.

[0117] In this embodiment, by constraining the transmission of PUCCH repetitions by the maximum threshold, not only can timely and effective PUCCH repetitions and transmission reliability be guaranteed, thus ensuring that the network side can make timely decisions on whether to initiate retransmission, but also invalid information transmission can be avoided, thereby improving system efficiency.

[0118] In some embodiments, the N time-domain resource units are time-domain resource units determined according to a time-slot format configuration that can be used to transmit the PUCCH repetition. The time-slot format configuration can be a semi-static frame structure configuration or a dynamic DCI configuration. The time-slot format configuration includes configured uplink and flexible symbols.

[0119] In other words, the terminal device can determine the time-domain resource units (RTRs) for PUCCH repetition from the RRTs available for transmission according to the time slot format configuration, based on the maximum threshold. For example, the N RRTs can serve as a first set of temporary RRTs for PUCCH repetition, and the terminal device can determine the RRTs for PUCCH repetition from this first set of temporary RRTs based on the maximum threshold. In other words, the terminal device can determine the first set of temporary RRTs for PUCCH repetition according to the time slot format configuration, and then determine the RRTs for PUCCH repetition from this first set of temporary RRTs based on the maximum threshold.

[0120] In some embodiments, the N time-domain resource units can be determined based on the uplink and flexible symbols of a semi-static configuration.

[0121] In one implementation, the conditions satisfied by the N time-domain resource units may include:

[0122] The start symbol for PUCCH is a flexible symbol other than the uplink symbol or the SS / PBCH symbol; and

[0123] The number of consecutive uplink symbols or flexible symbols other than SS / PBCH symbols, starting from the start symbol of PUCCH, is greater than or equal to the number of symbols in PUCCH.

[0124] In one implementation, the conditions satisfied by the N time-domain resource units may include:

[0125] The start symbol for PUCCH is a flexible symbol other than the uplink symbol or the SS / PBCH and CORESET 0 symbols; and

[0126] The number of consecutive uplink symbols or flexible symbols other than SS / PBCH symbols, starting from the start symbol of PUCCH, is greater than or equal to the number of symbols in PUCCH.

[0127] Of course, in other alternative embodiments of this application, the N time-domain resource units can also be determined based on the dynamic SFI indication. For example, the conditions satisfied by the N time-domain resource units may include: the start symbol of the PUCCH is a semi-statically determined uplink symbol or a dynamically indicated uplink symbol; and the number of consecutive semi-statically determined uplink symbols or dynamically indicated uplink symbols starting from the start symbol of the PUCCH is greater than or equal to the number of symbols of the PUCCH.

[0128] In some embodiments, N is the number of repetitions of the PUCCH, and the number of repetitions is greater than or equal to 1.

[0129] In some embodiments, N is configured by a network device.

[0130] In some embodiments, S220 may include:

[0131] The time-domain resource units for PUCCH repetition are determined based on preset rules and the maximum threshold.

[0132] In some embodiments, the preset rules include:

[0133] The time-domain resource element in which the PUCCH repeats is located before at least one of the following time-domain resource elements:

[0134] The time-domain resource unit where there are other uplink channels (e.g., other PUCCHs or PUSCHs besides the PUCCH corresponding to the PUCCH repetition) after the PUCCH repetition and the uplink transmission is conflicted.

[0135] The time-domain resource unit of the target downlink data after the PUCCH repetition, wherein the HARQ process of the target downlink data is the same as the HARQ process of the downlink data corresponding to the PUCCH repetition; and

[0136] The first time-domain resource unit (TROR) of the uplink channel corresponding to the (N+1)th SPS PDSCH; wherein, the downlink data corresponding to the PUCCH repetition is the Nth SPS PDSCH, and the position of the first TROR is determined according to the timing relationship, or the position of the first TROR is determined according to the timing relationship and the time slot format configuration.

[0137] In other words, on the one hand, the time-domain resource unit of the PUCCH repetition must not only satisfy: the interval between the position of the time-domain resource unit of the PUCCH repetition and the position of the time-domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and / or the interval between the position of the time-domain resource unit of the PUCCH repetition and the position of the time-domain resource unit determined by the timing relationship of the PUCCH repetition is less than or equal to the maximum threshold. On the other hand, the time-domain resource unit for PUCCH repetition also needs to satisfy the following: the time-domain resource unit for PUCCH repetition is located before at least one of the following time-domain resource units: the time-domain resource unit after the PUCCH repetition where there are other uplink channels and uplink transmissions conflict; the time-domain resource unit for the target downlink data after the PUCCH repetition, wherein the HARQ process of the target downlink data is the same as the HARQ process of the downlink data corresponding to the PUCCH repetition; and the first time-domain resource unit where the uplink channel corresponding to the (N+1)th SPS PDSCH is located; wherein the downlink data corresponding to the PUCCH repetition is the Nth SPS PDSCH, and the position of the first time-domain resource unit is determined according to the timing relationship, or the position of the first time-domain resource unit is determined according to the timing relationship and the timeslot format configuration.

[0138] Of course, in other alternative embodiments of this application, the preset rule may also be that the time domain resource unit that repeats PUCCH is located before other time domain units that meet certain conditions, and this application does not specifically limit this.

[0139] In some embodiments, the method 100 may further include:

[0140] On the time-domain resource unit of the PUCCH repetition, some or all of the PUCCH in the PUCCH repetition are transmitted.

[0141] In some embodiments, the time-domain resource unit is a time slot or a sub-time slot.
