[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on August 25, 2023, with application number 202311094548.2 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present invention relates to the field of wireless communication technologies, and in particular to a communication method and device. Background Art

[0004] When user equipment (UE) is in use, a connection can be established between the UE and the base station, allowing uplink and downlink data transmission. To improve the efficiency of uplink data transmission by the UE, the base station generally configures a configured grant (CG) scheduling transmission mechanism for the UE. That is, the base station pre-configures physical uplink shared channel (PUSCH) resources. The UE can send uplink data based on the pre-configured PUSCH resources without sending a scheduling request for uplink data transmission to the base station. PUSCH resources can be time domain resources or frequency domain resources, and each available PUSCH resource corresponds to a unique HARQ process ID.

[0005] For any CG cycle period, when multiple PUSCH resources are configured within the CG cycle period and repeated transmission is configured, that is, multiple uplink data complete multiple data transmissions within one CG cycle period, the base station cannot confirm the repeated uplink data based on the HARQ process identifier (hybrid automatic repeat request process identity document, HARQ process ID) corresponding to the available PUSCH resources, which increases the complexity of uplink data parsing.

[0009] The above design allows the second identifiers corresponding to the available PUSCH resources transmitting the same transport block to be the same. The terminal can determine that the available PUSCH resources with the same second identifier transmit the same transport block, and then perform operations such as combining the same transport blocks to obtain transport block combining gain.

[0010] In one possible design, the first identifier corresponding to the N+1th available PUSCH resource is determined based on the first identifier corresponding to the Nth available PUSCH resource and a first interval value, where N is an integer greater than 0.

[0061] In order to make the purpose, technical solutions and advantages of this application more clear, the application will be further described in detail below with reference to the accompanying drawings. The specific operation methods and functional descriptions in the method embodiments can also be applied to the device embodiments or system embodiments.

[0062] FIG1 is a schematic diagram illustrating a possible, non-limiting system. As shown in FIG1 , a communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the Internet 300 is also included.

[0063] The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1 , collectively referred to as 110) and at least one terminal (e.g., 120a to 120j in FIG. 1 , collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in FIG. 1).

[0064] Terminal 120 can be connected to RAN node 110 wirelessly. RAN node 110 is connected to core network 200 wirelessly or by wire. The core network device in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be a single physical device that integrates the logical functions of the core network device and the logical functions of the radio access network.

[0065] RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a fourth generation (4G) mobile communication system, a fifth generation (5G) mobile communication system, or a future-oriented evolution system, such as a sixth generation (6G) mobile communication system. RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0066] The RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and facilitates wireless access for terminals. In the subsequent description of this application, unless otherwise specified, the term "access network equipment" is used. Multiple RAN nodes 110 in the communication system 10 can be of the same type or different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing the RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN nodes 110 and terminals 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0067] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (such as 110a in FIG1 ), a micro base station or an indoor station (such as 110b in FIG1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, a RAN node may also be a server, a wearable device, a vehicle or an onboard device. For example, an access network device in vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in the embodiments of the present application may also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The RAN node in the embodiments of the present application may also be a logical node, a logical module, or software that can implement all or part of the functions of the RAN node.

[0068] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0069] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0070] The terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), extended reality (XR) (including virtual reality (VR) and augmented reality (AR)), industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal can be a mobile phone, a head-mounted display device, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

[0071] For example, the uplink data sent by a VR device to the access network device consists primarily of location and posture information. The upload data is small, typically only tens of kilobits per second. The downlink data received by the VR device from the access network device consists primarily of rendered video streams, which are much larger, reaching tens to hundreds of Mbps.

[0072] Taking AR as an example, the uplink data sent by AR to access network equipment primarily contains the visual information (including depth) required for perception. Therefore, uplink data can be clear and stable images or video streams, or extracted environmental feature information, resulting in a large data volume. Industry research and assessments indicate that the network uplink rate required for an initial experience with interactive AR services is approximately 2 Mbps, while an advanced experience requires 10-20 Mbps. The downlink data received by AR from access network equipment primarily consists of annotated visual information, resulting in a large data volume.

[0073] In an embodiment of the present application, the access network device can configure the terminal to transmit uplink data using a configured grant (CG) or uplink configured scheduling (CS). The access network device can allocate PUSCH resources through radio resource control (RRC) signaling or downlink control information (DCI), so that the terminal can periodically reuse the same PUSCH resources for uplink data transmission. PUSCH resources can be time domain resources or frequency domain resources, which are not limited here.

[0074] There are two types of CG. Type 1 configures the relevant parameters of CG transmission through RRC, such as the CG period, CG time domain and frequency domain resources, and activates the corresponding CG resources through RRC signaling. Type 2 configures the relevant parameters of CG transmission through RRC, such as the CG period, and configures and activates the corresponding CG resources through DCI.

[0075] In one possible implementation, a CG cycle period includes multiple transmission opportunities, and the multiple transmission opportunities include transmittable opportunities and non-transmittable opportunities, where each available transmission opportunity corresponds to an available PUSCH resource, and each non-transmittable opportunity corresponds to an unavailable PUSCH resource. In one design, since the transmission period of the XR service is 16.67ms, the duration of a CG cycle period can be set to 16.67ms. The CG cycle period is divided into 33 or 34 transmission opportunities, and the duration of each transmission opportunity is set to 0.5ms.

[0076] In one design, in a CG cycle period, one available PUSCH resource can be configured for one terminal, and different available PUSCH resources can be configured for different terminals. Each available PUSCH resource can only transmit one transport block (TB). Taking the configuration of an available PUSCH resource for terminal A as an example, as shown in Figure 2, the transmittable opportunity 1 appears periodically in different CG cycle periods, and the transmittable opportunity 1 in the CG cycle period 1 corresponds to an available PUSCH resource, and the transmittable opportunity 1 in the CG cycle period 2 corresponds to an available PUSCH resource. Terminal A can transmit the first frame of image through the available PUSCH resource corresponding to the transmittable opportunity 1 in the CG cycle period 1, and transmit the second frame of image through the available PUSCH resource corresponding to the transmittable opportunity 1 in the CG cycle period 2. Each frame of image is a transport block.

[0077] It should be understood that if at least one of the symbols indicated by the index row of the resource allocation table used in the pre-configured PUSCH resources overlaps with the DL symbol indicated by tdd-UL-DLConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, or overlaps with the symbol of the SS / PBCH block indexed by ssb-PositionsInBurst, then the transmission opportunity is not an available PUSCH resource, or in other words, the transmission opportunity is an unavailable PUSCH resource.

[0078] If the symbols indicated by the index row of the resource allocation table used in the pre-configured PUSCH resources do not overlap with the DL symbols indicated by tdd-UL-DLConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, or do not overlap with the symbols of the SS / PBCH block indexed by ssb-PositionsInBurst, then the transmission opportunity is an available PUSCH resource, or in other words, the transmission opportunity is an available PUSCH resource.

[0079] In one design, for services with a large amount of data to be uploaded by the terminal and that change dynamically, configuring one available PUSCH resource within a CG cycle period may not be able to complete the data transmission. Therefore, multiple available PUSCH resources can be configured for one terminal within a CG cycle period. Different multiple available PUSCH resources can be configured for different terminals. Taking the configuration of multiple available PUSCH resources for terminal A as an example, as shown in Figure 3, transmittable opportunity 1 and transmittable opportunity 2 appear periodically within different CG cycle periods. Transmittable opportunity 1 and transmittable opportunity 2 in CG cycle period 1 correspond to one available PUSCH resource respectively, and transmittable opportunity 1 and transmittable opportunity 2 in CG cycle period 2 correspond to one available PUSCH resource respectively. Each frame of image can be divided into two transmission blocks, namely transmission block 0 and transmission block 1. Transmission block 0 includes half of a frame of image, and transmission block 1 includes the other half of a frame of image. Terminal A can transmit the transmission block 0 corresponding to the first frame image through the available PUSCH resources corresponding to the transmission opportunity 1 in the CG cycle period 1, transmit the transmission block 1 corresponding to the first frame image through the available PUSCH resources corresponding to the transmission opportunity 2 in the CG cycle period 1, transmit the transmission block 0 corresponding to the second frame image through the available PUSCH resources corresponding to the transmission opportunity 1 in the CG cycle period 2, and transmit the transmission block 1 corresponding to the second frame image through the available PUSCH resources corresponding to the transmission opportunity 2 in the CG cycle period 2.

[0080] When multiple available PUSCH resources are configured for a terminal within a CG cycle period, in order to facilitate the terminal and the access network device to distinguish the transmission blocks transmitted by different available PUSCH resources, the terminal and the access network device can agree on a method for determining the first identifier corresponding to each available PUSCH resource.

[0081] When the uplink between the terminal and the access network device is a 3GPP NR uplink, the 3GPP NR uplink adopts an asynchronous hybrid automatic repeat request (HARQ) mechanism. The PUSCH resources (including available PUSCH resources and unavailable PUSCH resources) in each CG cycle period correspond to a HARQ process number, also known as a HARQ process ID. Each PUSCH resource uniquely specifies a HARQ process. When an error occurs in the transport block received by the base station through the available PUSCH resources, the terminal can be scheduled to retransmit the available PUSCH resources according to the HARQ process ID. Each HARQ process requires an independent HARQ buffer on the receiving side.

[0082] When the base station determines that the received transport block is erroneous, the base station needs to schedule the terminal to retransmit the available PUSCH resources, which will bring a lot of time overhead. In order to reduce the time overhead, the transport block can be repeatedly transmitted through the available PUSCH resources within a CG cycle period, including the following two possible repetition transmission modes, namely the first repetition transmission mode and the second repetition transmission mode.

[0083] The first repetition mode prioritizes new transmissions followed by repeated transmissions. As shown in Figure 4, CG cycle period 1 includes four transmittable opportunities: Transmittable Opportunity 0, Transmittable Opportunity 1, Transmittable Opportunity 2, and Transmittable Opportunity 3. Each transmittable opportunity corresponds to an available PUSCH resource. The terminal has two transport blocks to upload: Transport Block 0 and Transport Block 1. The available PUSCH resources corresponding to Transmittable Opportunity 0 and Transmittable Opportunity 1 are used for new transmissions of the transport blocks, while the available PUSCH resources corresponding to Transmittable Opportunity 2 and Transmittable Opportunity 3 are used for repeated transmissions of the transport blocks.

[0084] The available PUSCH resources corresponding to transmission opportunity 0 transmit transport block 0, and the available PUSCH resources corresponding to transmission opportunity 1 transmit transport block 1. The available PUSCH resources corresponding to transmission opportunity 2 repeatedly transmit transport block 0, and the available PUSCH resources corresponding to transmission opportunity 3 repeatedly transmit transport block 1.

[0085] The second repetition mode prioritizes retransmissions over renewing them. As shown in Figure 5, CG cycle period 1 includes four transmittable opportunities: Transmittable Opportunity 0, Transmittable Opportunity 1, Transmittable Opportunity 2, and Transmittable Opportunity 3. Each transmittable opportunity corresponds to an available PUSCH resource. The terminal has two transport blocks to upload: Transport Block 0 and Transport Block 1. The available PUSCH resources corresponding to Transmittable Opportunity 0 and Transmittable Opportunity 1 are used for retransmission and retransmission of transport blocks, while the available PUSCH resources corresponding to Transmittable Opportunity 2 and Transmittable Opportunity 3 are used for retransmission and retransmission of transport blocks.

[0086] The available PUSCH resources corresponding to transmission opportunity 0 transmit transport block 0, and the available PUSCH resources corresponding to transmission opportunity 1 repeatedly transmit transport block 0. The available PUSCH resources corresponding to transmission opportunity 2 transmit transport block 1, and the available PUSCH resources corresponding to transmission opportunity 3 repeatedly transmit transport block 1.

[0087] It should be understood that within a CG cycle period, the transmission block can be repeatedly transmitted once (i.e., the transmission block is transmitted twice in total), or the transmission block can be repeatedly transmitted multiple times. For ease of understanding, the embodiments of this application are explained by taking the repeated transmission of the transmission block once as an example, and no further details are given here.

[0088] Regardless of whether the first repeated transmission mode or the second repeated transmission mode is adopted, the HARQ process ID corresponding to each available PUSCH resource in the same CG cycle period is not the same. For example, in the present application, the HARQ process ID of the available PUSCH resource corresponding to the transmission opportunity 0 is 0, the HARQ process ID of the available PUSCH resource corresponding to the transmission opportunity 1 is 1, the HARQ process ID of the available PUSCH resource corresponding to the transmission opportunity 2 is 2, and the HARQ process ID of the available PUSCH resource corresponding to the transmission opportunity 3 is 3. Since the HARQ process IDs corresponding to the available PUSCH resources for transmitting the same transmission block are not the same, when the base station receives the transmission block, it cannot directly determine the same transmission block through the HARQ process ID, and thus cannot perform operations such as merging the same transmission blocks, which increases the implementation complexity, and cannot obtain the transmission block merging gain, thereby wasting system resources.

[0089] To solve the above problem, an embodiment of the present application provides a configuration method, as shown in the interaction diagram of FIG6 , which includes at least the following steps:

[0090] S610: The access network device sends first configuration information to the terminal. Correspondingly, the terminal receives the first configuration information from the access network device.

[0091] In an embodiment of the present application, the first configuration information may include the number of multiple transmission opportunities within the CG cycle period, the duration of the CG cycle period, the number of available first identifiers corresponding to the CG cycle period, and a first bias value.

[0092] The first configuration information can be used to determine the first identifiers corresponding to multiple available PUSCH resources in the CG cycle period. The first identifiers corresponding to different available PUSCH resources in any CG cycle period are not the same.

[0093] In one possible implementation, the first identifier corresponding to the available PUSCH resource may be a HARQ process ID. In the case where the first identifier is a HARQ process ID, the number of available first identifiers corresponding to the CG cycle period may be understood as the number of HARQ process IDs that can be used in the CG cycle period. Generally speaking, the number of HARQ process IDs used in the CG cycle period is less than or equal to the number of available first identifiers corresponding to the CG cycle period. For example, the number of available first identifiers corresponding to the CG cycle period is 4, and the HARQ process IDs used in the CG cycle period may be only 0 and 1, and 2 and 3 are not used.

[0094] The first identifier corresponding to the N+1th available PUSCH resource in the CG cycle period can be determined in the following manner: first determine the first identifier corresponding to the first CG transmission opportunity in the CG cycle period, and then determine the first identifier corresponding to the first available PUSCH resource based on the first identifier corresponding to the first CG transmission opportunity in the CG cycle period. The first identifier corresponding to the first CG transmission opportunity in the CG cycle period can be determined based on the first configuration information.

[0095] If the first available PUSCH resource corresponds to the first CG transmission opportunity, the first identifier corresponding to the first CG transmission opportunity is the first identifier corresponding to the first available PUSCH resource; if the first available PUSCH resource does not correspond to the first CG transmission opportunity, that is, the CG transmission opportunity corresponding to the first available PUSCH resource is located after the first CG transmission opportunity, then the sum of the first identifier corresponding to the first CG transmission opportunity and the first interval value is the first identifier corresponding to the first available PUSCH resource. The first interval value can be 1.

[0096] After the first identifier corresponding to the first available PUSCH resource is determined, the first identifier corresponding to the N+1th available PUSCH resource within the CG period can be determined based on the first identifier corresponding to the Nth available PUSCH resource and the first interval value, where N is an integer greater than 0. That is, the sum of the first identifier corresponding to the Nth available PUSCH resource and the first interval value is used as the first identifier corresponding to the N+1th available PUSCH resource. For example, when the first interval value is 1, the first identifier corresponding to the Nth available PUSCH resource is 1, and the first identifier corresponding to the N+1th available PUSCH resource is 2.

[0097] The first identifier corresponding to the first CG transmission opportunity within the CG cycle period includes the following two possible determination methods.

[0098] In a possible determination method, the first identifier corresponding to the first CG transmission opportunity in the CG period meets the following conditions: First identifier corresponding to the first CG transmission opportunity = [X*floor(CURRENT_symbol / periodicity)] mod nrofHARQ-Processes;

[0099] Among them, X represents the number of multiple transmission opportunities within the CG cycle period, CURRENT_symbol represents the absolute moment corresponding to the CG cycle period, periodicity represents the duration of the CG cycle period, floor() represents rounding down, mod represents modulo operation, and nrofHARQ-Processes represents the number of available first identifiers corresponding to the CG cycle period.

[0100] In another possible determination method, the first identifier corresponding to the first CG transmission opportunity in the CG period meets the following conditions: First identifier corresponding to the first CG transmission opportunity = [X*floor(CURRENT_symbol / periodicity)] mod nrofHARQ-Processes+harq-ProcID-Offset2;

[0101] Among them, X represents the number of multiple transmission opportunities within the CG cycle period, CURRENT_symbol represents the absolute moment corresponding to the CG cycle period, periodicity represents the duration of the CG cycle period, floor() represents rounding down, mod represents modulo operation, nrofHARQ-Processes represents the number of available first identifiers corresponding to the CG cycle period, and harq-ProcID-Offset2 represents the first offset value.

[0102] In one possible implementation, the absolute time (CURRENT_symbol) corresponding to the CG period satisfies:

[0103] CURRENT_symbol = (SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + slot number in the frame × numberOfSymbolsPerSlot + symbol number in the slot), where SFN represents the system frame number, numberOfSlotsPerFrame represents the number of consecutive transmission slots per frame, numberOfSymbolsPerSlot represents the number of consecutive symbols per transmission slot, slot number in the frame represents the transmission slot number within the frame, and symbol number in the slot represents the starting symbol index within the transmission slot.

[0104] For example, as shown in Figure 7, CG cycle period 1 includes 8 transmission opportunities, which are numbered 0, 1, 2, 3, 4, 5, 6, and 7. Among them, the transmission opportunity numbered 2 corresponds to an available PUSCH resource, the transmission opportunity numbered 5 corresponds to an available PUSCH resource, and the remaining transmission opportunities correspond to unavailable PUSCH resources. In CG cycle period 1, available PUSCH resources are denoted as U and unavailable PUSCH resources are denoted as D.

[0105] The eight transmission opportunities included in CG cycle period 2 are numbered 8, 9, 10, 11, 12, 13, 14, and 15. Transmission opportunity numbered 10 corresponds to available PUSCH resources, transmission opportunity numbered 13 corresponds to available PUSCH resources, and the remaining transmission opportunities correspond to unavailable PUSCH resources. Within CG cycle period 2, available PUSCH resources are denoted by U, and unavailable PUSCH resources are denoted by D.

[0106] The number value (X) of multiple transmission opportunities in CG cycle period 1 is 8, the absolute moment (CURRENT_symbol) corresponding to CG cycle period 1 is 0ms, the duration (periodicity) of CG cycle period 1 is 16.67ms, the number value (nrofHARQ-Processes) of available first identifiers corresponding to CG cycle period 1 is 4, the first offset value (harq-ProcID-Offset2) is 0, and the first interval value is 1. Therefore, the first identifier corresponding to the first CG transmission opportunity in CG cycle period 1 = [8*floor((0) / 16.67)]mod 4+0=0, that is, the first identifier corresponding to the transmission opportunity numbered 0 is 0, and the available PUSCH resource corresponding to the transmission opportunity numbered 2 is the first available PUSCH resource in CG cycle period 1. Therefore, the first identifier corresponding to the transmission opportunity numbered 2 is 0+1=1, and the first identifier corresponding to the transmission opportunity numbered 5 is 1+1=2.

[0107] The number (X) of multiple transmission opportunities in CG cycle period 2 is 8, the absolute moment (CURRENT_symbol) corresponding to CG cycle period 2 is 16.67ms, the duration (periodicity) of CG cycle period 2 is 16.67ms, the number (nrofHARQ-Processes) of available first identifiers corresponding to CG cycle period 2 is 4, the first offset value (harq-ProcID-Offset2) is 0, and the first interval value is 1. Therefore, the first identifier corresponding to the first CG transmission opportunity in CG cycle period 2 = [8*floor((16.67) / 16.67)]mod 4+0=0, that is, the first identifier corresponding to the transmission opportunity numbered 8 is 0, and the available PUSCH resource corresponding to the transmission opportunity numbered 10 is the first available PUSCH resource in CG cycle period 2. Therefore, the first identifier corresponding to the transmission opportunity numbered 10 is 0+1=1, and the first identifier corresponding to the transmission opportunity numbered 13 is 1+1=2.

[0108] S620, when multiple available PUSCH resources are repeatedly transmitted according to the first repetition transmission mode, the terminal determines a first value corresponding to the CG cycle time period, and the first value is determined by the terminal based on the number of multiple available PUSCH resources used to complete the initial transmission.

[0109] In an embodiment of the present application, each available PUSCH resource is used to transmit a transport block, and the first value can also be understood as the number of different transport blocks that the terminal needs to upload to the access network device within a CG cycle period.

[0110] For example, during CG cycle period 1, the terminal needs to upload two transport blocks to the access network device: transport block 0 and transport block 1. During a CG cycle period, the terminal can retransmit a transport block once, meaning that transport block 0 and transport block 1 are transmitted twice. The number of available PUSCH resources required to complete the initial transmission of transport block 0 and transport block 1 is 2, so the first value is 2.

[0111] S630: The terminal determines second identifiers corresponding to the plurality of available PUSCH resources based on the first value and the first identifiers corresponding to the plurality of available PUSCH resources. The second identifiers corresponding to the available PUSCH resources transmitting the same transport block are the same.

[0112] For a first available PUSCH resource among multiple available PUSCH resources, the first available PUSCH resource is any one of the multiple available PUSCH resources, and the second identifier corresponding to the first available PUSCH resource can be determined through the following two possible implementations.

[0113] In a first possible implementation manner, the terminal first performs a modulo operation on the first identifier and the first numerical value corresponding to the first available PUSCH resource to obtain the first reference identifier corresponding to the first available PUSCH resource, and then performs a modulo operation on the first reference identifier corresponding to the first available PUSCH resource and the number of available first identifiers corresponding to the CG cycle period to obtain the second identifier corresponding to the first available PUSCH resource.

[0114] For example, as shown in FIG8 , the number of available first identifiers corresponding to the CG cycle period in the first configuration parameter is 4. Therefore, the first identifier can take values ​​of 0, 1, 2, and 3.

[0115] CG cycle period 1 includes 33 transmission opportunities, and the number of configured multiple transmission opportunities (X) is 10. The first identifier corresponding to the first CG transmission opportunity in CG cycle period 1 is 0, the first identifier corresponding to the first available PUSCH resource in CG cycle period 1 is 1, the first identifier corresponding to the second available PUSCH resource in CG cycle period 1 is 2, the first identifier corresponding to the third available PUSCH resource in CG cycle period 1 is 3, and the first identifier corresponding to the fourth available PUSCH resource in CG cycle period 1 is 0.

[0116] The terminal needs to upload two transport blocks (transport block 0 and transport block 1) to the access network device, so two available PUSCH resources are required to realize the initial transmission of the transport block. The first value is 2, among which the first available PUSCH resource in CG cycle period 1 is used to transmit transport block 0, the second available PUSCH resource is used to transmit transport block 1, the third available PUSCH resource is used to transmit transport block 0, and the fourth available PUSCH resource is used to transmit transport block 1.

[0117] Performing a modulo operation on the first identifiers and first values ​​corresponding to the above four available PUSCH resources respectively, the first reference identifier corresponding to the first available PUSCH resource is 1%2=1, the first reference identifier corresponding to the second available PUSCH resource is 2%2=0, the first reference identifier corresponding to the third available PUSCH resource is 3%2=1, and the first reference identifier corresponding to the fourth available PUSCH resource is 0%2=0.

[0118] Perform modulo operations on the first reference identifiers corresponding to the above four available PUSCH resources and the number of available first identifiers corresponding to the CG cycle period, and obtain that the second identifier corresponding to the first available PUSCH resource is 1%4=1, the second identifier corresponding to the second available PUSCH resource is 0%4=0, the second identifier corresponding to the third available PUSCH resource is 1%4=1, and the second identifier corresponding to the fourth available PUSCH resource is 0%4=0.

[0119] In the above method, the terminal first performs a modulo operation on the first identifier and the first value corresponding to the first available PUSCH resource to obtain the first reference identifier corresponding to the first available PUSCH resource, and then performs a modulo operation on the first reference identifier corresponding to the first available PUSCH resource and the number of available first identifiers corresponding to the CG cycle period to obtain the second identifier corresponding to the first available PUSCH resource. Through the above two modulo operations, the second identifiers corresponding to the available PUSCH resources transmitting the same transport block can be made the same. The terminal can determine that the available PUSCH resources with the same second identifier transmit the same transport blocks, and then perform operations such as merging the same transport blocks to obtain a transport block merging gain.

[0120] In a second possible implementation manner, the terminal first performs a modulo operation on the first identifier and the first numerical value corresponding to the first available PUSCH resource to obtain a first reference identifier corresponding to the first available PUSCH resource, and then performs a modulo operation on the first reference identifier corresponding to the first available PUSCH resource and the number of available first identifiers corresponding to the CG cycle period to obtain a second reference identifier corresponding to the first available PUSCH resource. Then, based on the second reference identifier and the first offset value corresponding to the first available PUSCH resource, the terminal determines the second identifier corresponding to the first available PUSCH resource.

[0121] In this embodiment of the present application, the sum of the second reference identifier corresponding to the first available PUSCH resource and the first offset value may be used as the second identifier corresponding to the first available PUSCH resource.

[0122] In the above method, based on the first bias value, another method for determining the second identifier corresponding to the available PUSCH resource is provided. The terminal can determine that the available PUSCH resources with the same second identifier transmit the same transport blocks, and then perform operations such as merging the same transport blocks to obtain a transport block merging gain.

[0123] S640: When multiple available PUSCH resources are repeatedly transmitted according to the second repetition transmission mode, the terminal determines a second value corresponding to the CG cycle period.

[0124] In this embodiment of the present application, the first configuration information also includes a second value M. The terminal can obtain the second value from the first configuration information. The second value is used to configure the number of repeated transmissions. The second value configured by the base station and terminal protocol generally ensures that new transmissions and repeated transmissions of a single transmission block are completed within M transmission opportunities.

[0125] For example, as shown in Figure 9, CG cycle period 1 includes 33 transmission opportunities, of which transmission opportunities numbered 2, 7, 12, and 17 correspond to available PUSCH resources, and the remaining transmission opportunities correspond to unavailable PUSCH resources. Available PUSCH resources are denoted as U, and unavailable PUSCH resources are denoted as D.

[0126] The terminal has two transport blocks that need to be transmitted, transport block 0 and transport block 1. In order to repeat the transmission block once, the second value M of the first configuration information can be set to 10, that is, the two available PUSCH resources corresponding to the transmission opportunities numbered 0-9 are used to transmit transport block 0, and the two available PUSCH resources corresponding to the transmission opportunities numbered 10-19 are used to transmit transport block 1.

[0127] S650: The terminal determines third identifiers corresponding to the plurality of available PUSCH resources based on the second value and the first identifiers corresponding to the plurality of available PUSCH resources, wherein the third identifiers corresponding to the available PUSCH resources transmitting the same transport block are the same.

[0128] In the embodiment of the present application, the third identifier can be determined by the following steps as shown in FIG10 :

[0129] S1010, the terminal uses a second value to divide multiple transmission opportunities within the CG cycle period to obtain multiple transmission opportunity slots, wherein the number of transmission opportunities included in the transmission opportunity slot is the second value.

[0130] S1020: The terminal determines a third reference identifier corresponding to each available PUSCH resource in each transmission time period.

[0131] The third reference identifier corresponding to each available PUSCH resource in the (i+1)th transmission time period may be determined in the following manner:

[0132] The terminal first determines the first identifier corresponding to the first CG transmission opportunity in the CG cycle period, and then determines the third reference identifier corresponding to the available PUSCH resources in the first transmission opportunity slice based on the first identifier corresponding to the first CG transmission opportunity in the CG cycle period. Generally speaking, the third reference identifier corresponding to the available PUSCH resources in the first transmission opportunity slice is set to the first identifier corresponding to the first CG transmission opportunity in the CG cycle period. The third reference identifiers corresponding to the available PUSCH resources in the same transmission period slice are the same.

[0133] After the third reference identifier corresponding to the available PUSCH resource in the first transmission time slot is determined, the third reference identifier corresponding to each available PUSCH resource in the (i+1)th transmission time slot can be determined based on the third reference identifier corresponding to each available PUSCH resource in the (i)th transmission time slot and the first interval value; i is an integer greater than 0; the third reference identifiers corresponding to the available PUSCH resources in the same transmission time slot are the same.

[0134] S1030: For a first available PUSCH resource among multiple available PUSCH resources in the i-th transmission time slot, the terminal performs a modulo operation on a third reference identifier corresponding to the first available PUSCH resource and the number of available first identifiers corresponding to the CG cycle period to obtain a third identifier corresponding to the first available PUSCH resource. The first available PUSCH resource is any one of the multiple available PUSCH resources.

[0135] As shown in FIG11 , the second value is 10, and the CG cycle period 1 includes 33 transmission opportunities. Transmission opportunity slot 1 includes transmission opportunities numbered 0-9, and transmission opportunity slot 2 includes transmission opportunities numbered 10-19, and so on.

[0136] The available PUSCH resource corresponding to the transmission opportunity numbered 2 in transmission opportunity slot 1 is the first available PUSCH resource, the available PUSCH resource corresponding to the transmission opportunity numbered 7 in transmission opportunity slot 1 is the second available PUSCH resource, the available PUSCH resource corresponding to the transmission opportunity numbered 12 in transmission opportunity slot 2 is the third available PUSCH resource, and the available PUSCH resource corresponding to the transmission opportunity numbered 17 in transmission opportunity slot 2 is the fourth available PUSCH resource.

[0137] The first identifier corresponding to the first CG transmission opportunity in CG cycle period 1 is 0, the first identifier corresponding to the first available PUSCH resource in CG cycle period 1 is 1, the first identifier corresponding to the second available PUSCH resource in CG cycle period 1 is 2, the first identifier corresponding to the third available PUSCH resource in CG cycle period 1 is 3, and the first identifier corresponding to the fourth available PUSCH resource in CG cycle period 1 is 0.

[0138] The terminal needs to upload 2 transport blocks (transport block 0 and transport block 1) to the access network device, and the second value M is set to 10, where the first available PUSCH resource in CG cycle period 1 is used to transmit transport block 0, the second available PUSCH resource is used to transmit transport block 0, the third available PUSCH resource is used to transmit transport block 1, and the fourth available PUSCH resource is used to transmit transport block 1.

[0139] Since the first identifier corresponding to the first CG transmission opportunity in CG cycle period 1 is 0, the third reference identifiers corresponding to the available PUSCH resources in transmission opportunity slot 1 are all set to 0, that is, the third reference identifier corresponding to the first available PUSCH resource is 0, and the third reference identifier corresponding to the second available PUSCH resource is 0. If the first interval value is 1, the third reference identifiers corresponding to the available PUSCH resources in transmission opportunity slot 2 are all set to 0+1=1, that is, the third reference identifier corresponding to the third available PUSCH resource is 1, and the third reference identifier corresponding to the third available PUSCH resource is 1.

[0140] If the number value of the available first identifier corresponding to the CG cycle period is 4, then the third reference identifier corresponding to the available PUSCH resource and the number value of the available first identifier corresponding to the CG cycle period are respectively performed modulo operation, and the third identifier corresponding to the first available PUSCH resource is 0%4=0, the third identifier corresponding to the second available PUSCH resource is 0%4=0, the third identifier corresponding to the third available PUSCH resource is 1%4=1, and the third identifier corresponding to the fourth available PUSCH resource is 1%4=1.

[0141] By using the third identifiers corresponding to the multiple available PUSCH resources determined by the above method, the terminal can determine that the available PUSCH resources with the same third identifier transmit the same transport blocks, and then perform operations such as merging the same transport blocks to obtain transport block merging gain.

[0142] Another way to determine the third identifier corresponding to the first available PUSCH resource is as follows:

[0143] For the first available PUSCH resource among multiple available PUSCH resources located in the i-th transmission time period, the terminal performs a modulo operation on the third reference identifier corresponding to the first available PUSCH resource and the number of available first identifiers corresponding to the CG cycle period to obtain the fourth reference identifier corresponding to the first available PUSCH resource, and then determines the third identifier corresponding to the first available PUSCH resource based on the fourth reference identifier corresponding to the first available PUSCH resource and the first bias value.

[0144] In this embodiment of the present application, the sum of the fourth reference identifier corresponding to the first available PUSCH resource and the first offset value may be used as the third identifier corresponding to the first available PUSCH resource.

[0145] In the above method, based on the first bias value, another method for determining the third identifier corresponding to the available PUSCH resource is provided. The terminal can determine that the available PUSCH resources with the same third identifier transmit the same transport blocks, and then perform operations such as merging the same transport blocks to obtain a transport block merging gain.

[0146] S660, when multiple available PUSCH resources are repeatedly transmitted according to the first repetition transmission mode, the access network device determines a first value corresponding to the CG cycle time period, and the first value is determined by the access network device based on the number of multiple available PUSCH resources used to complete the initial transmission.

[0147] In the embodiment of the present application, the method for the access network device to determine the first value may refer to the method for the terminal to determine the first value in step 620.

[0148] S670: The access network device determines second identifiers corresponding to the plurality of available PUSCH resources based on the first value and the first identifiers corresponding to the plurality of available PUSCH resources. The second identifiers corresponding to the available PUSCH resources transmitting the same transport block are the same.

[0149] In the embodiment of the present application, the method for the access network device to determine the second identifiers corresponding to multiple available PUSCH resources respectively can refer to the method for the terminal to determine the second identifiers corresponding to multiple available PUSCH resources respectively in step 630.

[0150] S680: When multiple available PUSCH resources are repeatedly transmitted according to the second repetition transmission mode, the access network device determines a second value corresponding to the CG cycle period.

[0151] In the embodiment of the present application, the method for the access network device to determine the second value may refer to the method for the terminal to determine the second value in step 640.

[0152] S690: The access network device determines third identifiers corresponding to the plurality of available PUSCH resources based on the second value and the first identifiers corresponding to the plurality of available PUSCH resources, wherein the third identifiers corresponding to the available PUSCH resources transmitting the same transport block are the same.

[0153] In the embodiment of the present application, the method for the access network device to determine the third identifiers corresponding to multiple available PUSCH resources respectively can refer to the method for the terminal to determine the third identifiers corresponding to multiple available PUSCH resources respectively in step 650.
