Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a data transmission method and apparatus. Background Technology

[0002] In the field of communication technology, in order to ensure the reliability of data transmission, the Hybrid Automatic Repeat Request (HARQ) method is usually used for feedback and retransmission when transmitting data.

[0003] In existing technologies, for the same terminal device, all services of the device use the same HARQ operation. For example, all services may report data reception status, or none may report data reception status. However, a terminal device may have multiple services with different transmission requirements. While HARQ technology can improve data transmission reliability, feedback and retransmission also introduce transmission latency. Existing technologies cannot perform different data transmission processing according to the needs of different services, resulting in low flexibility in data transmission. Summary of the Invention

[0004] This application provides a data transmission method and apparatus, enabling terminal devices to perform the same HARQ operation for the same service, thereby improving the flexibility of data transmission.

[0005] In a first aspect, a data transmission method is provided, applicable to a communication device, such as a terminal device, comprising: receiving first information; the first information being used to instruct the HARQ function of a Hybrid Automatic Repeat Request (HARQ) process associated with a first configuration grant to be enabled or disabled, the first configuration grant being configured by Radio Resource Control (RRC) signaling; and performing data transmission using the first configuration grant according to the first information.

[0006] In the method provided in this application embodiment, the first information ensures that the HARQ function status of all HARQ processes associated with the same configured grant is consistent. For example, when a terminal device transmits data through a configured grant, the HARQ function of all HARQ processes is enabled; or, when a terminal device transmits data through a configured grant, the HARQ function of all HARQ processes is disabled. Therefore, this application embodiment can ensure that the HARQ function status of the HARQ processes used by multiple transport opportunities with the same configuration grant in RRC signaling configuration remains consistent. When a terminal device performs the same service through the same configuration grant, it uses the same HARQ operation, better matching the service requirements of the terminal device and improving data transmission performance. Each transport opportunity with a configuration grant corresponds to one HARQ process.

[0007] In conjunction with the first aspect, in a first possible implementation of the first aspect, the method further includes: receiving second information; the second information is used to instruct the HARQ function of the first HARQ process to be enabled and / or the HARQ function of the second HARQ process to be disabled.

[0008] In the method provided in this application embodiment, the available HARQ processes and their HARQ function states can also be configured via the second information. When the first information indicates the HARQ function state of the first configuration authorization, the terminal device can select a HARQ process whose HARQ function state is consistent with that indicated by the first information from the available processes. This ensures that data transmissions performed through the first configuration authorization execute the same HARQ operation, either all with HARQ function enabled or all with HARQ function disabled, thereby improving the flexibility of data transmission.

[0009] In conjunction with the first possible implementation of the first aspect, in the second possible implementation of the first aspect, the second information is only applicable to dynamically scheduled resources, and the method further includes: an indication to ignore the second information when using the first configuration authorization for data transmission.

[0010] In the method provided in this application embodiment, the terminal device can determine the HARQ function state of the dynamically scheduled resource (also known as the dynamic authorization) based on the second information, and determine the HARQ function state of the configuration authorization (also known as the configuration resource) only based on the first information, ignoring the indication of the second information. Therefore, it can be guaranteed that the first configuration authorization is mapped to the HARQ process that is consistent with the HARQ function state indicated by the first information. Data transmission performed through the first configuration authorization performs the same HARQ operation, either enabling or disabling the HARQ function, thereby improving the flexibility of data transmission.

[0011] In conjunction with the first possible implementation of the first aspect, in the third possible implementation of the first aspect, using the first configuration authorization to perform data transmission based on the first information includes: using the first configuration authorization to perform data transmission based on the first information and the second information.

[0012] In the method provided in this application embodiment, both the first information and the second information may be applicable to configuration authorization, and the HARQ function status of the first configuration authorization can be determined based on the first information and the second information.

[0013] In combination with the third possible implementation of the first aspect, in the fourth possible implementation of the first aspect, the priority of the first information is higher than the priority of the second information.

[0014] In the method provided in this application embodiment, the first information has a higher priority than the second information. When both the first information and the second information may be applicable to configuration authorization, the HARQ function status of the first configuration authorization can be determined based on the first information.

[0016] In this embodiment of the application, after determining the HARQ function state of the first configuration authorization, the first configuration authorization can also be mapped to a HARQ process with the same HARQ function state to ensure that the data transmission performed through the first configuration authorization performs the same HARQ operation.

[0017] In conjunction with the fifth possible implementation of the first aspect, in the sixth possible implementation of the first aspect, the process of the third HARQ process is the i-th HARQ process in the first process set, and the first process set is the set of HARQ processes that are consistent with the HARQ functional state of the first configuration authorization; i satisfies the following formula: i = [floor(T / P)]modulo M; where T is the identifier of the time unit in which the first configuration authorization is located, and the time unit is a symbol, a time slot, or a subframe, P is the period of the configuration authorization, M is the number of processes in the first process set, floor is the floor operation, and modulo is the modulo operation.

[0018] This application provides a method for determining a HARQ process index. Based on the HARQ process index, a HARQ process in a first process set can be determined, thereby mapping the first configuration authorization to a HARQ process with a consistent HARQ functional state.

[0019] In conjunction with the fifth possible implementation of the first aspect, in the seventh possible implementation of the first aspect, the third HARQ process is the j-th HARQ process in the first process set.

[0020] This application provides another method for determining the HARQ process index. Based on the HARQ process index, a HARQ process in the first process set can be determined, thereby mapping the first configuration authorization to a HARQ process with the same HARQ functional state.

[0021] In conjunction with the fifth possible implementation of the first aspect, in the eighth possible implementation of the first aspect, the third HARQ process is the t-th HARQ process in the first process set. The first process set is the set of HARQ processes that are consistent with the HARQ functional state of the first configuration authorization, and t satisfies the following formula: t={[floor(T / P)]modulo N}modulo M; where T is the identifier of the time unit where the first configuration authorization is located, and the time unit is a symbol, a time slot, or a subframe; P is the period of the configuration authorization; N is the total number of HARQ processes configured by RRC signaling; floor is the floor operation; modulo is the modulo operation; and M is the number of processes in the first process set.

[0024] In the method provided in this application embodiment, the first information ensures that the HARQ function status of all HARQ processes associated with the same configured grant is consistent. For example, when a terminal device transmits data through a configured grant, the HARQ function of all HARQ processes is enabled; or, when a terminal device transmits data through a configured grant, the HARQ function of all HARQ processes is disabled. Therefore, this application embodiment can ensure that the HARQ function status of the HARQ processes used by multiple transport opportunities with the same configuration grant in RRC signaling configuration remains consistent.

[0074] The method provided in the embodiments of this application can be used... Figure 1The communication system shown. (Reference) Figure 1 The communication system may include multiple terminal devices and network devices.

[0075] Figure 1 A schematic diagram of a communication system to which the technical solution provided in this application applies is given. The communication system may include multiple network devices (only network device 100 is shown) and multiple terminal devices (only terminal device 201 and terminal device 202 are shown in the figure). Figure 1 This is for illustrative purposes only and does not constitute a limitation on the applicable scenarios of the technical solutions provided in this application. This communication system supports side-to-side communication, such as device-to-device (D2D) communication and vehicle-to-everything (V2X) communication.

[0076] Network devices and terminal devices can communicate uplink and downlink via cellular links (Uu links), while terminal devices can communicate with each other via sidelinks, such as D2D communication, V2X communication, and machine-type communication (MTC).

[0077] In one possible implementation, network device 100 is mounted on a high-altitude aircraft (e.g., a satellite) that orbits the Earth periodically, while terminal devices (e.g., terminal device 201) are located on the ground. Because network device 100 provides a large signal coverage area and has a short orbital period, terminal device 201 generally will not move out of the same geographical area when the signal coverage provided by network device 100 periodically appears in that area. (Reference) Figure 1 When network device 100 reaches a certain point in its orbit, terminal device 201 can obtain system information from network device 100 and communicate within the signal coverage area of ​​network device 100. When network device 100 continues to operate, terminal device 201 will leave the signal coverage area of ​​network device 100, and network device 100 will no longer provide signal coverage for terminal device 201.

[0078] In scenarios where network equipment is carried by satellites, satellites can be classified into low-earth orbit (LEO) satellites, medium-earth orbit (MEO) satellites, geostationary earth orbit (GEO) satellites, and highly elliptical earth orbit (HEO) satellites, depending on their orbital altitude.

[0079] In one possible implementation, the network device 100 (e.g., a base station) is on the ground, and the terminal device communicates with the core network device through the ground-based network device.

[0080] Network device 100 can be any device with wireless transceiver capabilities. This includes, but is not limited to: evolved LTE base stations (E-UTRAN NodeB, e-NodeB, or eNB), base stations (gNodeB or gNB) or transmission / reception points (TRPs) in 5G or new radio (NR) access technologies, base stations evolved from 3GPP, access nodes, wireless relay nodes, and wireless backhaul nodes in WiFi systems. Base stations can be: macro base stations, micro base stations, pico base stations, small cells, radio controllers in CRAN (Content Access Network) scenarios, centralized units (CUs), and / or distributed units (DUs). Network devices can also be servers, wearable devices, or vehicle-mounted devices. The following explanation uses a base station as an example. The multiple network devices can be the same type of base station or different types of base stations. Base stations can communicate with terminal devices or communicate with terminal devices through relay stations. Terminal devices can communicate with multiple base stations using different technologies. For example, a terminal device can communicate with a base station that supports LTE networks, or with a base station that supports 5G networks, and can also support dual connections with both LTE and 5G base stations.

[0081] A terminal device (e.g., terminal device 201) is a device with wireless transceiver capabilities that can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can be deployed in the air (e.g., on airplanes, balloons, and satellites). The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal device, etc. The embodiments of this application do not limit the application scenarios. A terminal may also be referred to as a terminal device, user equipment (UE), access terminal device, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, terminal device, wireless communication device, UE agent, or UE device, etc. A terminal can be fixed or mobile. The terminal device of this application can also be an on-board module, on-board component, on-board chip, or on-board unit built into a vehicle as one or more components or units. The vehicle can implement the methods of this application through the built-in on-board module, on-board component, on-board chip, or on-board unit.

[0082] First, the terminology used in the embodiments of this application will be explained:

[0083] (1) Configure grant

[0084] refer to Figure 2 In a configuration-based scheduling method (e.g., semi-static scheduling), the base station can configure periodically occurring resources (transmission opportunities) via radio resource control (RRC) signaling. These periodically occurring resources can be referred to as configured grants. It is understood that a configured grant includes multiple transmission opportunities, for example... Figure 2 The configuration authorization shown includes four periodic transmission opportunities.

[0085] In this embodiment, configuration grant can also be referred to as configuration scheduling or configuration resource. Configuration grant can include a first type of configuration resource (type 1) and a second type of configuration resource (type 2). Configuration resources can also be called grant-free grants, and configuration resource type 2 can also be called SPS (semi-persistent scheduling). For SPS resources, the base station can also activate the configured grant through downlink control information (DCI), and then the terminal device can perform data transmission through the configured grant. When the terminal device uses the first type of configuration resource for data transmission, it does not need to activate it using DCI.

[0086] It is understandable that when using configuration resources for data transfer, i.e., transferring data on configuration authorization, if the HARQ function is configured during data transfer, the HARQ process needs to be executed according to the HARQ function status.

[0087] (2) Dynamic grant

[0088] In dynamic scheduling, the base station sends a Direct Access Query (DCI) to the terminal device via the physical downlink control channel (PDCCH). The DCI dynamically indicates the resources configured by the base station and HARQ information. The HARQ information may include the HARQ process number, redundancy version, etc. This method of dynamically scheduling resources using DCI can be called dynamic granting, or dynamic resource scheduling.

[0089] (3) HARQ process

[0090] A single HARQ entity can contain multiple HARQ processes. During data transmission, terminal devices and network devices can use multiple HARQ processes to transmit different data in parallel. Different data transmissions are associated with different HARQ processes, and terminal devices and network devices can identify the corresponding data transmissions through process identifiers. In this embodiment, using HARQ processes for data transmission can be understood as associating a HARQ process with a single data transmission. For example, if process 1 transmits data packet 1 on a transmission resource (e.g., configuration authorization or dynamic authorization), it can be understood that this transmission of data packet 1 is associated with process 1. When the terminal device and network device process the data, they will place data packet 1 in the HARQ buffer corresponding to process 1 for processing. If there is a subsequent retransmission of data packet 1, the same HARQ process will be used to ensure that the terminal device and network device can identify that the transmission is a retransmission of data packet 1, and thus perform HARQ merging.

[0091] For example, for downlink data transmission, the network device can use a specific HARQ process to send data, receive HARQ feedback information from the terminal device corresponding to that process, and retransmit the data to the terminal device based on the feedback information. For uplink data transmission, the terminal device can use a specific HARQ process to send data to the network device and receive HARQ feedback information from the network device corresponding to that HARQ process.

[0092] The HARQ feedback information is used to indicate the data reception status of a specific HARQ process. If data is successfully received, the HARQ feedback information for that process is an acknowledgement (ACK). If data is not successfully received, the HARQ feedback information for that process is a negative acknowledgement (NACK).

[0093] It should be noted that the terminal device's Media Access Control (MAC) entity maintains multiple HARQ entities for the terminal device, and one HARQ entity can maintain multiple parallel HARQ processes.

[0094] When using the HARQ process to transmit data, after the receiving end successfully decodes the data packet received from the sending end, the receiving end sends an ACK to the sending end. After receiving the ACK, the sending end will then send the next data packet.

[0095] If a data packet fails to decode, the receiving end can discard it and send a NACK to the sending end. Upon receiving the NACK, the sending end will retransmit the data packet. In one possible implementation, the terminal device can also use HARQ with soft combining technology to improve decoding performance. For example, undecoded data packets can be stored in the corresponding HARQ buffer of the process and combined with subsequently received retransmitted data packets. Decoding the combined data packet improves reliability compared to decoding a single data packet.

[0096] (4) HARQ process number

[0097] The HARQ process number is the HARQ ID used to identify a HARQ process. Each HARQ entity in the terminal device maintains a certain number of HARQ processes, which can be distinguished by the HARQ ID.

[0098] (5) HARQ Function Status

[0099] HARQ functionality status can include an on or off state, or in other words, an enabled or disabled state.

[0100] When HARQ is enabled for a certain process, both the sending and receiving ends need to maintain a corresponding HARQ buffer for that process to store the corresponding data packets. The receiving end needs to send HARQ feedback based on the received data packets, and the sending end can retransmit or retransmit based on the HARQ feedback. HARQ feedback includes ACK or NACK.

[0101] If the HARQ function for a certain process is disabled, the sender and receiver do not need to maintain a HARQ buffer for that process. After the sender sends a data packet, it does not need to buffer the data packet. When the receiver receives the data packet, it does not need to send a HARQ feedback to the sender, regardless of whether the reception is successful or unsuccessful. If the reception fails, it can choose to discard the data packet without putting it in the buffer to wait for HARQ merging.

[0102] In existing configuration scheduling technology, when a terminal device can use multiple periodically occurring configured grants for data transmission, for a transmission opportunity of a configured grant, the terminal device can calculate a HARQ process number based on the time-domain symbol of the transmission opportunity. The HARQ process identified by this process number then transmits data through that configuration grant. For example, the HARQ process number satisfies the following formula:

[0103] HARQ process number = [floor(T / P)] modulo M(1)

[0104] Where T represents the identifier CURRENT_symbol of the symbol that will appear during this transmission opportunity, P represents the period of the configuration resource, and M represents the maximum number of HARQ processes in a HARQ entity configured for the terminal device. The HARQ entity is the HARQ entity corresponding to the serving cell where the terminal device is camped, and the HARQ processes maintained by the HARQ entity can be configured by the network device through RRC signaling. In formula (1), "floor" is the floor operation and "modulo" is the modulo operation.

[0105] Typically, configuration authorization is configured for services with the same Quality of Service (QoS) or for the same service. However, for the same service on a terminal device, the calculated HARQ process may have HARQ enabled on some transmission opportunities and disabled on others, resulting in inconsistent HARQ functionality for the same service and impacting data transmission performance. For example, latency-sensitive services need to disable HARQ and not send HARQ feedback information to reduce data transmission latency. However, based on the process described above, assuming configuration authorization is configured for this service, when the terminal device uses the configuration resource on some transmission opportunities, it may map the configuration resource to a HARQ process with HARQ enabled, leading to increased transmission latency and failing to meet service requirements.

[0106] Example, reference Figure 3 The terminal device maintains 1 to 8 HARQ processes for a single HARQ entity. HARQ processes 1 to 4 have their HARQ functionality enabled, while HARQ processes 5 to 8 have their HARQ functionality disabled. Assume that the calculation is based on the above formula (1)... Figure 2 The four authorized transmission machines configured in the configuration use process numbers 1, 2, 5, and 6, respectively. HARQ functionality is enabled for processes 1 and 2, while it is disabled for processes 5 and 6. Assuming the terminal device's service is latency-sensitive, enabling HARQ and receiving ACK or NACK responses from the terminal device would increase transmission latency, failing to meet service requirements.

[0107] This application provides a data transmission method in which a terminal device receives first information. The first information is used to indicate whether the HARQ function of a HARQ process associated with a first configuration resource is enabled or disabled. The first configuration resource is configured by Radio Resource Control (RRC) signaling. The terminal device can also use the first configuration resource for data transmission based on the first information. For example, it can determine whether to enable the HARQ function when using the first configuration resource for data transmission based on the first information. In the method provided by this application, the first information can ensure that the HARQ function status of all HARQ processes associated with the same configured grant is consistent. For example, when the terminal device transmits data through a configured grant, the HARQ function of all HARQ processes is enabled, or when the terminal device transmits data through a configured grant, the HARQ function of all HARQ processes is disabled. It can be seen that this application can ensure that the HARQ function status of the HARQ processes used by multiple transmission opportunities with the same configuration grant configured by RRC signaling remains consistent. When the terminal device performs the same service through the same configuration grant, it uses the same HARQ operation, which better matches the service requirements of the terminal device and improves data transmission performance. Each transmission opportunity with a configuration grant corresponds to a HARQ process.

[0119] Figure 4b This is a structural diagram of a network device. The structure of network device 420 can be referenced. Figure 4b The structure shown.

[0120] The network device includes at least one processor 4201, at least one memory 4202, at least one transceiver 4203, at least one network interface 4204, and one or more antennas 4205. The processor 4201, memory 4202, transceiver 4203, and network interface 4204 are connected, for example, via a bus. The antenna 4205 is connected to the transceiver 4203. The network interface 4204 is used for the network device to connect to other communication devices via a communication link, for example, the network device connects to core network elements via an S1 interface. In this embodiment, the connection may include various interfaces, transmission lines, or buses, etc., and this embodiment is not limited to these. Optionally, the network device 420 may not include the memory 4202.

For example, processor 4201 may be a single-core (single-CPU) processor or a multi-core (multi-CPU) processor. At least one processor 4201 may be integrated into a single chip or located on multiple different chips.

[0122] The memory in this application embodiment, such as memory 4202, may include at least one of the following types: read-only memory (ROM) or other types of static storage devices capable of storing static information and instructions; random access memory (RAM) or other types of dynamic storage devices capable of storing information and instructions; or electrically erasable programmable-only memory (EEPROM).

[0123] The memory 4202 can exist independently and be connected to the processor 4201. Optionally, the memory 4202 can also be integrated with the processor 4201, for example, integrated within a single chip.

The order of the downmixing and analog-to-digital conversion processes is adjustable. Transceiver 4203 can selectively perform one or more stages of upmixing and digital-to-analog conversion on the modulated digital baseband signal or digital intermediate frequency signal to obtain a radio frequency signal. The order of the upmixing and digital-to-analog conversion processes is also adjustable. Digital baseband signals and digital intermediate frequency signals can be collectively referred to as digital signals. The transceiver can be called a transceiver circuit, transceiver unit, transceiver device, transmitting circuit, transmitting unit, or transmitting device, etc.

[0125] It should be noted that the communication device 420 can be a complete network device, a component or assembly that implements the functions of the network device, or a communication chip. When the communication device 420 is a communication chip, the transceiver 4203 can be the interface circuit of the chip, which is used to read and output baseband signals.

[0126] This application provides a HARQ indication method, such as... Figure 5 As shown, the method includes the following steps:

[0127] 501. The network device sends first information to the terminal device. The first information is used to instruct whether the HARQ function of the HARQ process associated with the first configuration authorization is enabled or disabled, and the first configuration authorization is configured by Radio Resource Control (RRC) signaling.

[0128] It's understandable that the first configuration grant is a Configured grant. See the example for reference. Figure 2The network device configures the configuration authorization via RRC signaling, meaning the first configuration authorization is semi-statically scheduled. This configuration authorization includes multiple periodically occurring transmission opportunities, during which the terminal device can use the configuration authorization to transmit data.

[0129] The HARQ process associated with the first configuration authorization is the HARQ process used by the transmission opportunity under the first configuration authorization. In different transmission opportunities under the first configuration authorization, a single HARQ process is used for data transmission through the first configuration authorization. This can be understood as a data transmission operation performed on one transmission opportunity under the first configuration authorization being identified by the HARQ process, including data reception and data transmission through the first configuration authorization. It should be noted that the data transmission includes the transmission of data and / or signaling.

[0130] For example, if the first configuration grant includes four transport opportunities A, B, C, and D, and the HARQ processes used by these four transport opportunities are processes 1 to 4, then the HARQ processes associated with the first configuration grant are processes 1 to 4.

[0131] In one possible implementation, the first information can indicate the HARQ function status of all HARQ processes associated with the configuration authorization of an RRC signaling configuration, so as to ensure that the HARQ function status of all HARQ processes associated with the same configuration authorization is consistent.

[0132] Furthermore, the HARQ process associated with the first configuration authorization is used by terminal devices and network devices to transmit data through the first configuration authorization. Taking downstream transmission as an example, the HARQ process associated with the first configuration authorization is HARQ process 1. The network device can use HARQ process 1 to send new or retransmitted data to the terminal device through the first configuration authorization. The terminal device can use HARQ process 1 to receive data sent by the network device through the first configuration authorization, and can send ACK or NACK feedback to the network device in response to HARQ process 1. The first information is an instruction for the first configuration authorization. Each HARQ process associated with the first configuration authorization enables or disables the HARQ function according to the instruction of the first information.

[0133] In a specific implementation, the first information can be a single bit with two states: a first state and a second state. If the first information is in the first state, it indicates that the HARQ function of the HARQ process associated with the first configuration authorization is enabled; if the first information is in the second state, it indicates that the HARQ function of the HARQ process associated with the first configuration authorization is disabled. For example, the first state is "1" and the second state is "0".

[0134] Alternatively, the first piece of information can be a boolean type, indicating whether the HARQ function is on or off by being "true" or "false";

[0135] Alternatively, the first information can indicate the status of the HARQ function by whether a certain information element or field appears in the signaling. For example, assuming the signaling contains the first information element, it indicates that the HARQ function is enabled; if the first information element is not contained, it indicates that the HARQ function is disabled.

[0136] In one possible implementation, the first indication information may be included in the RRC signaling used to configure the first configuration authorization.

[0137] In another possible implementation, the first indication information may be included in a DCI used to activate a certain configuration authorization. In yet another possible implementation, the first indication information may be included in a MAC CE (control element) used to indicate the HARQ function status.

[0138] 502. The terminal device receives the first information and performs data transmission using the first configuration authorization based on the first information.

[0139] Specifically, the terminal device can determine the HARQ function status of the first configuration authorization based on the first information. The HARQ function status of the first configuration authorization can be the HARQ function status indicated by the first information, that is, the HARQ function status of the HARQ process associated with the first configuration authorization. For example, when transmitting data through the first configuration authorization, it may be whether the HARQ function of the HARQ process used by each transmission opportunity under the first configuration authorization is enabled.

[0140] After the terminal device determines the HARQ function status of the first configuration authorization, it needs to associate the first configuration authorization with a specific HARQ process each time it uses the first configuration authorization for data transmission. That is, it uses the HARQ process associated with the first configuration authorization for data transmission, and executes the HARQ function according to the HARQ function status indicated by the first information.

[0141] Specifically, using the HARQ process associated with the first configuration authorization for data transmission can also be understood as using the HARQ process associated with the first configuration authorization to identify data transmission performed on the first configuration authorization, wherein data transmission may include: data reception or data transmission or corresponding HARQ feedback or retransmission operations.

[0142] Furthermore, executing the HARQ function according to the HARQ function status indicated by the first information can also be understood as executing the corresponding HARQ operation according to the HARQ function status of the first configuration authorization. For example, if the HARQ function of the first configuration authorization is enabled, the terminal device or network device will perform HARQ feedback or HARQ retransmission on the data received under the first configuration authorization. Additionally, the sending end can buffer the data sent under the first configuration authorization so that it can retransmit the data after receiving a NACK from the receiving end. The receiving end can also buffer the data sent under the first configuration authorization so that it can merge and decode the data after receiving a retransmission from the sending end.

[0143] It should be noted that network devices can configure available HARQ processes or the total number of HARQ processes for terminal devices. Furthermore, they can specify which HARQ processes have HARQ enabled and which have HARQ disabled.

[0144] For example, Figure 5 The method further includes step 503: the terminal device receives second information from the network device; the second information is used to indicate that the HARQ function of the first HARQ process is enabled and / or the HARQ function of the second HARQ process is disabled. It should be noted that, in this embodiment, the second information can be used to indicate the HARQ function status of a HARQ process. The first and second HARQ processes are merely examples. The second information can also indicate other HARQ processes and the HARQ process function status of other HARQ processes, such as the third HARQ process described in this embodiment.

[0145] The second information is an instruction for the HARQ process. Compared to the first information, the second information is granular at the HARQ process level. Each HARQ process configured by the second information can enable or disable the HARQ function according to the instructions in the second information. Specifically, the second instruction can be included in the RRC signaling used to configure HARQ, or in the RRC signaling used to configure the configured grant, or in the RRC signaling used to configure the physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH). Alternatively, the second information can also be included in the MACCE or DCI used to change the HARQ function status.

[0146] Example, reference Figure 3The network device configures HARQ processes 1 to 8 for the terminal device through the second information. The second information can also indicate that the HARQ function of HARQ processes 1 to 4 is started and the HARQ function of HARQ processes 5 to 8 is turned off.

[0147] In this embodiment of the application, the terminal device combines the first information and the second information to associate the first configuration authorization with a HARQ process that has a consistent HARQ functional state through the following two methods:

[0148] Method 1: The scope or priority of the first and second information can be limited. Based on this, the terminal device can determine the HARQ function status of the first configuration authorization through the following two methods: a and b.

[0149] Method a: The second information applies only to dynamically scheduled resources. The HARQ function status of a configuration authorization (e.g., a first configuration authorization) can be determined based on the first information, and the HARQ function status of a dynamic authorization can also be determined based on the second information. The HARQ function status of a dynamic authorization can be the HARQ function status of the HARQ process associated with the dynamic authorization. The HARQ process associated with the dynamic authorization can be the HARQ process used when transmitting data via dynamic authorization.

[0150] For dynamic scheduling, network devices can specify the HARQ process to be used in the DCI, and terminal devices can determine whether the HARQ function of the HARQ process used in this scheduling is enabled or disabled based on the second information.

[0151] For example, in Figure 6 In the example shown, the network device configures HARQ processes 1 to 8 for the terminal device through the second information. The second information can also indicate that the HARQ function of HARQ processes 1 to 4 is started and the HARQ function of HARQ processes 5 to 8 is turned off.

[0152] The network device also indicates the dynamically scheduled resource F and the process number "5" of the HARQ process used for data transmission on the dynamically scheduled resource F via DCI. According to the second information, the HARQ function of HARQ process 5 is disabled; therefore, the HARQ function is disabled when using HARQ process 5 for data transmission on the dynamically scheduled resource F. For example, the network device does not cache the data corresponding to HARQ process 5, and the terminal device does not send HARQ feedback information indicating the reception status of the data corresponding to HARQ process 5.

[0153] For semi-static scheduling, base stations can configure periodically distributed configured grants for data transmission. For each configured grant, the terminal device can calculate a HARQ process number for each corresponding transmission opportunity and use the HARQ process corresponding to that process number to transmit data through that configured grant at that transmission opportunity. Furthermore, based on the first information, the HARQ function status of the HARQ process used by each transmission opportunity under the configured grant is determined to be either enabled or disabled.

[0154] In one possible implementation, when the terminal device or network device uses the first configuration authorization to transmit data, it ignores the indication of the second information and performs the corresponding HARQ operation according to the HARQ function status indicated by the first information.

[0155] Optionally, the HARQ function of the HARQ process associated with the first configuration authorization can be changed according to the first information. When the associated HARQ process is dynamically authorized and used up again, the corresponding HARQ operation is performed according to the HARQ function status indicated by the second information.

[0156] Alternatively, the HARQ function of the HARQ process associated with the first configuration authorization can be changed according to the first information. When the associated HARQ process is reconfigured and authorized and its use is exhausted, the corresponding HARQ operation can be performed according to the HARQ function status indicated by the first information.

[0157] Example, reference Figure 7 Assuming the first information indicates that the HARQ function of the HARQ process associated with the first configuration authorization is enabled, and the second information indicates that the HARQ function of HARQ processes 1-4 is enabled, while the HARQ function of processes HARQ5-8 is disabled, then when the terminal device uses process 5 during the third transmission opportunity of the first configuration authorization, it will enable the HARQ function of HARQ process 5 according to the first information.

[0158] Optionally, after HARQ process 5 is used up, its HARQ function is disabled according to the second information. "HARQ process is used up" means that the data packet corresponding to the HARQ process was successfully received, or the HARQ process was used for new data packet transmission.

[0159] Method b: The second information is applicable to dynamic resource scheduling and configuration authorization. The terminal device uses the first configuration authorization to transmit data based on the first information and the second information.

[0160] In practice, the terminal device can determine the HARQ function status of the HARQ process associated with the first configuration authorization based on the higher priority information between the first and second information. The priority can be predefined, preconfigured, or indicated in the first and second information.

[0161] In one possible implementation, the first information has a higher priority than the second information. For configuration authorization, when the indications of the first and second information conflict, the HARQ state of the HARQ process is determined according to the indication of the first information, while the indication of the second information is ignored.

[0162] Taking HARQ process 5 as an example, if the first information indicates that the HARQ function of HARQ process 5 is enabled, and the second information indicates that the HARQ function of HARQ process 5 is enabled, then the HARQ function of HARQ process 5 is enabled.

[0163] Taking HARQ process 5 as an example, if the first information indicates that the HARQ function of HARQ process 5 is turned off, and the second information indicates that the HARQ function of HARQ process 5 is turned on, then the HARQ function of HARQ process 5 is turned off.

[0164] Taking HARQ process 5 as an example, if the first information indicates that the HARQ function of HARQ process 5 is turned off, and the second information indicates that the HARQ function of HARQ process 5 is turned off, then the HARQ function of HARQ process 5 is turned off.

[0165] Taking HARQ process 5 as an example, if the first information indicates that the HARQ function of HARQ process 5 is turned off, and the second information indicates that the HARQ function of HARQ process 5 is turned on, then the HARQ function of HARQ process 5 is turned off.

[0166] In Method 1, after determining the HARQ function status of the first configuration authorization, the terminal device can also calculate the process number of the HARQ process associated with the first configuration authorization according to the calculation method of the prior art. When using the corresponding HARQ process to transmit data through the first configuration authorization, the terminal device can perform the corresponding HARQ operation according to the HARQ function status of the first configuration authorization.

[0167] Specifically, the HARQ process number associated with the first configuration authorization is calculated according to formula (1) described above. When the HARQ process corresponding to the HARQ process number (e.g., the third HARQ process described in this application embodiment) transmits data through the first configuration authorization, the HARQ function of the HARQ process corresponding to the HARQ process number is enabled or disabled according to the HARQ function status of the first configuration authorization. For example, based on the symbol identifier of the first configuration authorization and the HARQ process number calculated by formula (1) above, it is "5". Assuming that the HARQ function status of the first configuration authorization is enabled as determined above, when transmitting data through the first configuration authorization, the HARQ process corresponding to process number "5" (e.g., the third HARQ process described in this application embodiment) can be used to identify a data transmission and enable the HARQ function. For example, the terminal device provides ACK or NACK feedback for this data transmission.

[0168] Method 2: Without limiting the scope or priority of the first and second information, the terminal device can determine the HARQ function status of the first configuration authorization based on the first information, calculate the index of the HARQ process number associated with the first configuration authorization, and determine the HARQ process based on the index of the HARQ process number. The first configuration authorization is then associated with a HARQ process that has the same HARQ function status.

[0169] For example, the index of the third HARQ process associated with the first configuration authorization is calculated, and the third HARQ process can be identified based on the index. Alternatively, the third HARQ process can be associated with the first configuration authorization, and during data transmission through a transmission opportunity of the first configuration authorization, the third HARQ process is used to identify this data transmission. It should be noted that associating the third HARQ process with the first configuration authorization can be understood as mapping the first configuration authorization to the third HARQ process, or as associating the third HARQ process with a data transmission performed on the first configuration authorization.

[0170] In the specific implementation, it can be determined that the index of the third HARQ process is an index relative to the first process set, used to indicate the position of the third HARQ process in the first process set.

[0171] In one possible implementation, the first process set is a set of HARQ processes whose HARQ function status is consistent with the first configuration authorization. For example, if some HARQ processes configured by the network device for a certain HARQ entity of the terminal device have HARQ function enabled, while others have HARQ function disabled, then the first process set is either a set of processes with HARQ function enabled or a set of processes with HARQ function disabled. Specifically, if the first information indicates that HARQ function is enabled, the first process set is the set of HARQ processes with HARQ function enabled among the available HARQ processes configured by RRC signaling. If the first information indicates that HARQ function is disabled, then the first process set is the set of HARQ processes with HARQ function disabled among the available HARQ processes configured by RRC signaling.

[0172] Specifically, the index of the HARQ process can be determined using the following methods: E, F, and G.

[0173] Method E: Calculate the index of the HARQ process based on the number M of HARQ processes in the first process set.

[0174] For example, the index i of the third HARQ process is determined according to formula (2), where i satisfies the following formula (2):

[0175] i = [floor(T / P)] modulo M (2)

[0176] Wherein, T is the identifier of the time unit in which the first configuration authorization is located, the time unit being a symbol, a time slot, or a subframe, P is the period of the configuration authorization, M is the number of processes in the first process set, floor is the floor operation, and modulo is the modulo operation.

[0177] In this approach, the index of a HARQ process will not exceed the number of HARQ processes M in the first process set. After determining the index i, it needs to be mapped to a HARQ process, and the number of indices will not exceed the number of HARQ processes in the first set.

[0178] In one possible implementation, the third HARQ process is the i-th HARQ process in the first process set. Specifically, the M HARQ processes in the first process set are arranged in a certain order, and the i-th HARQ process is the sorted i-th HARQ process. For example, the M HARQ processes are arranged in descending order of process ID, or in ascending order of process ID.

[0179] Example, reference Figure 8The first configuration authorization includes four transmission opportunities: A, B, C, and D. The network device configures HARQ processes 1 to 8 for the terminal device through RRC signaling. Among them, the HARQ function of HARQ processes 1-3 and HARQ process 6 is enabled, while the HARQ function of HARQ processes 4-5 and HARQ processes 7-8 is disabled.

[0180] Assuming the first indication information indicates that the HARQ function of the HARQ process associated with the first configuration authorization is enabled, when the index i of the third HARQ process associated with the transmission opportunity D is calculated using formula (2) as "4", it means that the third HARQ process is the 4th HARQ process in the first process set. Figure 6 In the example shown, the first process set is the HARQ processes with HARQ enabled among HARQ processes 1 to 8, that is, the first process set is the set of HARQ processes 1-3 and HARQ process 6. Following the ascending order of process number, the fourth HARQ process in the first process set is HARQ process 6, meaning the third HARQ process is HARQ process 6. Transmission opportunity D actually uses HARQ process 6.

[0181] Method F: Calculate the index of HARQ processes based on the maximum number N of HARQ processes configured by RRC signaling, where N>M.

[0182] For example, the index j of the third HARQ process is determined according to formula (3), where j satisfies the following formula (3):

[0183] j = [floor(T / P)] modulo N (3)

[0184] Wherein, T is the identifier of the time unit in which the first configuration grant is located, the time unit is a symbol, a time slot, or a subframe, P is the period of the configuration grant, N is the total number of HARQ processes configured in the RRC signaling, floor is floor operation, and modulo is modulo operation. The time unit in which the first configuration grant is located can be the time unit in which one transmission opportunity of the first configuration grant is located.

[0185] In this approach, the calculated index j of the HARQ process may be greater than the number M of HARQ processes in the first process set. Here, T is the identifier of the time unit where the first configuration grant is located, and the time unit is a symbol, time slot, or subframe; P is the period of the configuration grant; N is the total number of HARQ processes configured by RRC signaling; floor is floor operation; and modulo is modulo operation. The time unit where the first configuration grant is located can be the time unit of one transmission opportunity of the first configuration grant.

[0186] (1) When j is not greater than M, the third HARQ process is the j-th HARQ process in the first process set. Specifically, the M HARQ processes in the first process set are arranged in a certain order, and the j-th HARQ process is the j-th HARQ process after sorting. For example, the M HARQ processes are arranged in descending order of process number, or the M HARQ processes are arranged in ascending order of process number.

[0187] Example, reference Figure 9 The first configuration authorization includes four transmission opportunities: A, B, C, and D. The network device configures HARQ processes 1 to 8 for the terminal device through RRC signaling. Among them, the HARQ function of HARQ processes 1-3 and HARQ process 6 is enabled, while the HARQ function of HARQ processes 4-5 and HARQ processes 7-8 is disabled.

[0188] Assume that the first indication information indicates that the HARQ function of the HARQ process associated with the first configuration authorization is enabled, and the first process set is the set of HARQ processes 1-3 and HARQ process 6. Using formula (3), the indices j of the HARQ processes used by the terminal device in the four transmission opportunities are calculated as "1", "2", "3" and "4", which will not exceed the number of HARQ processes in the first process set, which is "4".

[0189] (2) When j is greater than M, it is also necessary to take the modulo of index j so that the first configuration authorization is mapped to the HARQ process in the first process set.

[0190] Example, reference Figure 10 The first configuration authorization includes five transmission opportunities: A, B, C, D, and E. The network device configures HARQ processes 1 to 8 for the terminal device through RRC signaling. Among them, the HARQ function of HARQ processes 1-3 and HARQ process 6 is enabled, while the HARQ function of HARQ processes 4-5 and HARQ processes 7-8 is disabled.

[0191] Assuming the first indication information indicates that the HARQ function of the HARQ process associated with the first configuration authorization is enabled, when the index j of the HARQ process used in transmission opportunity E is calculated to be "5" using formula (4), the first process set is the HARQ process with HARQ function enabled among HARQ processes 1 to 8, that is, the first process set is the set of HARQ processes 1-3 and HARQ process 6. It can be seen that the index "5" of the third HARQ process exceeds the number of HARQ processes "4" in the first process set, and can continue to take the modulo of 5 to obtain the index "1" of the third HARQ process. For example, 5modulo4 = 1, that is, the index t of the third HARQ process is 1, which means that the third HARQ process is the first HARQ process in the first process set. Figure 6 In the example shown, in ascending order of process ID, the first HARQ process in the first process set is HARQ process 1, meaning the third HARQ process is HARQ process 1. In transmission opportunity D, HARQ process 1 is actually used.

[0192] Method G: The index t of the HARQ process is calculated using formula (4). This index t will not exceed the number M of HARQ processes in the first process set. The first configuration authorization can be mapped to the HARQ process in the first process set according to the index t.

[0193] For example, the index t of the third HARQ process is determined according to formula (4), where t satisfies the following formula (4):

[0194] t={[floor(T / P)]modulo N}modulo M (4)

[0195] Wherein, T is the identifier of the time unit in which the first configuration authorization is located, the time unit is a symbol, a time slot, or a subframe, P is the period of the configuration authorization, N is the total number of HARQ processes configured by RRC signaling, floor is the floor operation, modulo is the modulo operation, and M is the number of processes in the first process set.

[0196] In one possible implementation, the third HARQ process is the t-th HARQ process in the first process set. Specifically, the M HARQ processes in the first process set are arranged in a certain order, and the t-th HARQ process is the sorted t-th HARQ process. For example, the M HARQ processes are arranged in descending order of process ID, or in ascending order of process ID.

[0197] Example, reference Figure 11 The first configuration authorization includes four transmission opportunities: A, B, C, D, and E. The network device configures HARQ processes 1 to 8 for the terminal device through RRC signaling. Among them, the HARQ function of HARQ processes 1-3 and HARQ process 6 is enabled, while the HARQ function of HARQ processes 4-5 and HARQ processes 7-8 is disabled.

[0198] Assuming the first indication information indicates that the HARQ function of the HARQ process associated with the first configuration authorization is enabled, when the index t of the HARQ process used in the transmission opportunity E is calculated using formula (4) as "2", that is, the index t of the third HARQ process is 2, which means that the third HARQ process is the second HARQ process in the first process set. Figure 11In the example shown, in ascending order of process ID, the second HARQ process in the first process set is HARQ process 2, meaning the third HARQ process is HARQ process 2. In transmission opportunity D, HARQ process 2 is actually used.

[0199] The above three methods of determination are only possible examples. In specific implementations, the terminal device can determine the process number of the third HARQ process according to other possible methods.

[0200] It should be noted that the methods 1, 2, 3a, 4b, 5, and 6g described in this application embodiment are not limited to terminal devices. Network devices can also execute methods 1, 2, 3a, 3b, 5, and 6g to determine the HARQ function status of the first configuration authorization and associate the HARQ process that is consistent with the first configuration authorization with the HARQ function status.

[0201] In the method provided in this application embodiment, the first information ensures that the HARQ function status of all HARQ processes associated with the same configured grant is consistent. For example, when a terminal device transmits data through a configured grant, the HARQ function of all HARQ processes is enabled; or, when a terminal device transmits data through a configured grant, the HARQ function of all HARQ processes is disabled. Therefore, this application embodiment can ensure that the HARQ function status of the HARQ processes used by multiple transport opportunities with the same configuration grant in RRC signaling configuration remains consistent. When a terminal device performs the same service through the same configuration grant, it uses the same HARQ operation, better matching the service requirements of the terminal device and improving data transmission performance. Each transport opportunity with a configuration grant corresponds to one HARQ process.
