[0028] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below with reference to the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0029] Before describing the embodiments of the present application in detail, a brief description of the related technologies is given.

[0030] Non-terrestrial networks (NTNs) use satellite communications to provide communications services to users on the ground. Compared to terrestrial cellular networks, satellite communications offer many unique advantages. First, satellite communications are not restricted by user location. For example, conventional terrestrial communications cannot reach areas such as oceans, high mountains, and deserts where communications equipment cannot be deployed or where there is a sparse population. However, satellite communications, because a single satellite can cover a large area and orbits the Earth, theoretically every corner of the globe can be covered. Second, satellite communications have high social value. Satellite communications can provide low-cost coverage in remote mountainous areas and poor, underdeveloped countries and regions, enabling people in these areas to enjoy advanced voice communications and mobile internet technologies, narrowing the digital divide with developed regions and promoting their development. Third, satellite communications offer long range, and increasing communication distance does not significantly increase communication costs. Finally, satellite communications are highly stable and unaffected by natural disasters.

[0031] Communication satellites are categorized by their orbital altitude into Low-Earth Orbit (LEO), Medium-Earth Orbit (MEO), Geostationary Earth Orbit (GEO), and High Elliptical Orbit (HEO). The following briefly describes LEO and GEO.

[0032] LEO orbital altitudes range from 500km to 1500km, corresponding to an orbital period of approximately 1.5 to 2 hours. Signal propagation delay for single-hop communication between terminal devices is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The short signal propagation distance and low link loss reduce the transmit power requirements of terminal devices.

[0033] GEO orbits at an altitude of 35,786 km and revolves around the Earth every 24 hours. Signal propagation delay for single-hop communication between terminal devices is typically 250 milliseconds. To ensure satellite coverage and increase the capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A single satellite can form dozens or even hundreds of beams to cover the ground; a single satellite beam can cover a ground area tens to hundreds of kilometers in diameter.

[0034] In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

[0035] The following is a brief description of the Hybrid Automatic Repeat reQuest (HARQ) mechanism in the New Radio (NR) system.

[0036] The NR system includes two levels of retransmission mechanisms: the HARQ mechanism at the Media Access Control (MAC) layer and the Automatic Repeat Request (ARQ) mechanism at the Radio Link Control (RLC) layer. Retransmission of lost or erroneous data is primarily handled by the HARQ mechanism at the MAC layer, supplemented by the retransmission function at the RLC layer. The HARQ mechanism at the MAC layer provides fast retransmissions, while the ARQ mechanism at the RLC layer provides reliable data transmission.

[0037] HARQ uses a stop-and-wait protocol to send data. In the stop-and-wait protocol, after the transmitter sends a transport block (TB), it stops data transmission to wait for confirmation information. In this way, the transmitter stops data transmission after each transmission to wait for confirmation information, which will result in very low user throughput. Therefore, the NR system uses multiple parallel HARQ processes. When one HARQ process is waiting for confirmation information, the transmitter can use another HARQ process to continue sending data. These HARQ processes together form a HARQ entity, which combines the stop-and-wait protocol to allow continuous data transmission. HARQ is divided into uplink HARQ and downlink HARQ. Uplink HARQ is for uplink data transmission, and downlink HARQ is for downlink data transmission. Uplink HARQ and downlink HARQ are independent of each other.

[0038] Based on the current NR protocol regulations, each service cell corresponding to the terminal device has its own HARQ entity. Each HARQ entity maintains a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes. Each uplink and downlink carrier can support a maximum of 16 HARQ processes. The network device can indicate the maximum number of HARQ processes to the terminal device through the radio resource control (RRC) signaling semi-static configuration according to the network deployment. If the network device does not provide the corresponding configuration parameters, the default number of HARQ processes for the downlink is 8, and the maximum number of HARQ processes supported by each carrier for the uplink is always 16. Each HARQ process corresponds to a HARQ process identifier (ID). For the downlink, the broadcast control channel (BCCH) uses a dedicated broadcast HARQ process. For the uplink, message 3 (Msg3) in the random process is transmitted using HARQ ID 0.

[0039] For terminal devices that do not support downlink spatial division multiplexing, each downlink HARQ process can only process one TB simultaneously. For terminal devices that support downlink spatial division multiplexing, each downlink HARQ process can process one or two TBs simultaneously. Each uplink HARQ process of the terminal can process one TB simultaneously.

[0040] HARQ is categorized into synchronous and asynchronous methods in the time domain, and non-adaptive and adaptive methods in the frequency domain. NR systems use asynchronous and adaptive HARQ mechanisms for both uplink and downlink. Asynchronous HARQ means retransmissions can occur at any time, and the interval between the retransmission of the same TB and the previous transmission is not fixed. Adaptive HARQ can change the frequency domain resources and modulation and coding scheme (MCS) used for retransmissions.

[0041] The following is a brief description of the Logical Channel Prioritization (LCP) in the NR system.

[0042] Similar to the long term evolution (LTE) system, in the NR system, network equipment allocates uplink transmission resources based on each terminal device, rather than on each radio bearer. The terminal device determines which radio bearer data can be placed in the allocated uplink transmission resources for transmission.

[0043] Based on the uplink transmission resources configured by the network device, the terminal device needs to determine the amount of data to be transmitted for each logical channel in the initial MAC Protocol Data Unit (PDU); in some cases, the terminal device also needs to allocate resources to the MAC Control Element (CE). To achieve uplink logical channel multiplexing, a priority needs to be assigned to each uplink logical channel. For a MAC PDU of a given size, if multiple uplink logical channels have data transmission requirements at the same time, the resources of the MAC PDU are allocated in descending order of the logical channel priorities corresponding to each uplink logical channel. At the same time, to ensure fairness between different logical channels, the concept of Prioritized Bit Rate (PBR) is introduced. When the terminal device performs logical channel multiplexing, it is necessary to first ensure the minimum data rate requirement of each logical channel. This avoids the situation where the high-priority uplink logical channel always occupies the uplink resources allocated to the terminal device by the network device, resulting in the terminal device's other low-priority uplink logical channels being "starved" due to not being allocated uplink resources.

[0044] The following is a brief description of the Configured Grant (CG).

[0045] In order to better serve periodic services, the concept of pre-configured resources is introduced, which is called Semi-Persistent Scheduling (SPS) for downlink and CG for uplink.

[0046] The NR system supports the following two types of uplink configuration grant transmission:

[0047] 1. Physical Uplink Shared Channel (PUSCH) transmission based on configured grant Type 1.

[0048] The network device configures all transmission resources and transmission parameters, including time domain resources, frequency domain resources, time domain resource period, MCS, number of repetitions, frequency hopping, and number of HARQ processes, through RRC signaling. After receiving the RRC configuration parameters, the terminal device can immediately use the configured transmission parameters to perform PUSCH transmission on the configured time and frequency resources.

[0049] 2. PUSCH transmission based on configured grant Type 2.

[0050] A two-step resource configuration approach is adopted: first, the network device uses homogeneous RRC signaling to configure transmission resources and transmission parameters including the period, number of repetitions, frequency hopping, and number of HARQ processes of time domain resources. Then, the Physical Downlink Control Channel (PDCCH) scrambled by the Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) activates PUSCH transmission based on the second type of configuration authorization, and simultaneously configures other transmission resources and transmission parameters including time domain resources, frequency domain resources, and MCS. When the terminal device receives the RRC configuration parameters, it cannot immediately use the resources and parameters configured with the parameters for PUSCH transmission. Instead, it must receive the corresponding PDCCH activation and configure other resources and parameters before it can perform PUSCH transmission.

[0051] Since the maximum number of HARQ processes supported by the terminal device is 16, for each CG configuration, the network device configures a limited number of HARQ process numbers for the terminal device, and the terminal device uses these HARQ process numbers in a polling manner to perform uplink transmission on the CG resource. Assume that the HARQ process number of the CG resource at time t0 and the HARQ process of the CG resource at time t1 are both HARQ ID i. When the terminal device assembles MAC PDU1 at time t0, it stores MAC PDU1 in HARQ ID i. At time t1, since it is the same HARQ process used at time t0, even if MAC PDU1 has not been correctly transmitted at this time, MAC PDU1 will be discarded (flush). Therefore, a configured grant timer (configured GrantTimer) is introduced for each HARQ process. The maintenance method of Configured Grant Timer is:

[0052] If the terminal device performs uplink transmission on the resources scheduled by PDCCH, and the HARQ process used for the uplink transmission can be used for configured authorized transmission, the terminal device starts or restarts the configuredGrant Timer corresponding to the HARQ process. If the terminal device performs uplink transmission on the configured authorized resources, the terminal device starts or restarts the configured Grant Timer corresponding to the HARQ process. If the terminal device receives a PDCCH indicating that configuredgrant Type 2 is activated, the terminal device stops the running configured Grant Timer. Before the configured Grant Timer corresponding to a certain HARQ process times out, the MAC PDU saved in the HARQ process cannot be flushed.

[0053] In the NR system, after the terminal device uses the CG resources to send the MAC PDU, it starts the CG timer and begins to monitor the PDCCH encrypted by CS-RNTI and C-RNTI. The sent MAC PDU is saved in the HARQ buffer. If the terminal device receives a PDCCH encrypted by C-RNTI to schedule uplink transmission, no matter what value the new data indication (NDI) in the PDCCH takes, the terminal device considers that the NDI has flipped, and the terminal device obtains the MAC PDU to be transmitted from the multiplexing and assembly entity. In addition, once the transmission is completed on the dynamically scheduled resources, the new MAC PDU will be saved in the HARQ buffer, and the MAC PDU previously transmitted by the CG will be flushed. This will cause the data transmitted by the CG to be lost.

[0054] Because CG resources are pre-configured, network equipment does not know when a terminal device will perform an uplink transmission on a CG resource unless it detects an uplink transmission on that CG resource. In terrestrial networks of NR systems, where the propagation delay between the terminal device and the network equipment is small, network equipment may be able to mitigate the aforementioned data loss issue to some extent by implementing, for example, dynamic scheduling of uplink transmissions after uplink transmission detection on each CG resource.

[0055] Compared to the cellular networks used in traditional NR systems, NTNs have longer propagation delays between terminal devices and satellites, especially in GEO scenarios, where the delay is around tens of milliseconds. If dynamic uplink scheduling is only performed after CG resource uplink detection, it will inevitably cause significant scheduling delays. Consequently, the probability of data loss in NTN scenarios is higher.

[0056] While implementing data transmission, the applicant discovered that different services have different Quality of Service (QoS) attributes, such as those sensitive to latency or transmission reliability. For reliability-sensitive data, if the HARQ buffer for CG transmission is cleared every time dynamically scheduled resources are used, data transmission reliability will be reduced.

[0071] An optional processing flow of the data packet reassembly method provided in the embodiment of the present application is as follows: Figure 2 As shown, the following steps are included:

[0072] In step S201, when the terminal device transmits data on the configured authorized resources and the configured authorization timer is running, the terminal device receives scheduling information and first indication information for new uplink transmission; the first indication information is used to determine whether data packets are reassembled for the transmission of dynamic authorized resources.

[0073] In some embodiments, the first indication information may be sent by the network device to the terminal device; the first indication information may be carried in an RRC message.

[0074] In some embodiments, the scheduling information for the new uplink transmission includes: scheduling information for scheduling the new uplink transmission using a PDCCH scrambled by a C-RNTI.

[0075] In some embodiments, the hybrid automatic repeat request process associated with the uplink new transmission is the same as the hybrid automatic repeat request process associated with transmitting data on the configured granted resources.

[0076] In some embodiments, when the first indication information is used to determine to perform data packet reassembly, the method may further include:

[0077] Step S202: The terminal device reassembles the data packet through the multiplexing and assembling entity.

[0078] In some embodiments, the method may further include:

[0079] Step S203: The terminal device transmits the reassembled data packet using the dynamically authorized resources in the scheduling information.

[0080] For step S201, the first indication information can indicate whether to perform data packet reassembly for the transmission of dynamic authorized resources based on different dimensions. For example: the first indication information indicates whether to perform data packet reassembly for the transmission of dynamic authorized resources based on CG; that is, for the data transmitted on the resources of a certain CG, whether to perform data packet reassembly for the data transmitted on the CG resources when the dynamic authorized resources are used to transmit data. For example: the first indication information indicates whether to perform data packet reassembly for the transmission of dynamic authorized resources based on logical channels; that is, for the data corresponding to one or more logical channels, whether to perform data packet reassembly for the data corresponding to the logical channels when the dynamic authorized resources are used to transmit data after the CG resources are used to transmit data. For example: the first indication information indicates whether to perform data packet reassembly for the transmission of dynamic authorized resources based on MAC CE; that is, for one or more MAC CEs, whether to perform data packet reassembly for the MAC CE when the dynamic authorized resources are used to transmit data after the CG resources are used to transmit data.

[0081] The data packet reassembly method provided in the embodiment of the present application is described below based on the above three different dimensions.

[0082] When the terminal device transmits data on the configured authorized resources and the configured authorization timer is running, the terminal device receives the C-RNTI-encrypted PDCCH scheduled uplink new transmission sent by the network device.

[0083] In some scenarios, for each CG configuration, the network device sends first indication information to the terminal device, where the first indication information is used to determine whether the terminal device performs data packet reassembly when transmitting data using dynamic authorized resources scheduled by PDCCH.

[0084] In specific implementation, the network device may send the first indication information to the terminal device through an RRC message, such as the network device configuring the configured Grant Config through an RRC reconfiguration message; the configured Grant Config includes, in addition to the nrofHARQ-Processes parameter indicating the number of HARQ processes available for the uplink resource, the periodicity parameter indicating the time interval between uplink grants, the CS-RNTI, and the CG timer and other parameters, the first indication information; wherein the first indication information is indication information indicating whether to reassemble the data packet (rebuild MAC PDU). In network implementation, the transmission of logical channels with high transmission reliability requirements can be configured on the CG configuration, that is, the allowedCGlist in the LogicalChannelConfig of the logical channel that meets the first condition for transmission reliability is pointed to the configured Grant config.

[0085] During specific implementation, the network device may also send the first indication information via the PDCCH that schedules the terminal device to transmit data using the dynamically authorized resources; that is, the first indication information is carried in the PDCCH.

[0086] If the rebuild MAC PDU is configured to be on in the first indication information, it can be determined that after the terminal device transmits data on the configured authorized resources, if the terminal device receives scheduling information for new uplink transmission, the terminal device needs to reassemble the data packet before using the dynamic authorized resources to transmit data; wherein, the data transmitted by the dynamic authorized resources and the data transmitted by the configured authorized resources are for the same HARQ process.

[0087] When performing data packet reassembly, the terminal device can obtain data other than padding from the MAC PDU stored in the HARQ buffer; wherein the data may be data and / or MAC CE corresponding to each logical channel transmitted on the CG resource. The terminal device sends the obtained data to the multiplexing and assembly entity; in the multiplexing and assembly entity, the obtained data and the existing data in the multiplexing and assembly entity are combined to generate a MAC PDU for uplink transmission. The new MAC PDU is transmitted using the dynamic granted resources scheduled by the PDCCH.

[0088] In the scenario where the first indication information is for configuration authorization, a detailed processing flow of data transmission provided by the embodiment of the present application is as follows: Figure 3As shown, the terminal device uses the configured authorized resources to transmit logical channel 1 (LCH1) and logical channel 3 (LCH3), and the MAC PDU transmitted using the configured authorized resources is stored in the HARQ buffer. During the operation of the configured authorization timer, if the terminal device receives scheduling information and first indication information for uplink new transmission scheduled by the PDCCH encrypted with C-RNTI sent by the network device, and the first indication information indicates data packet reassembly, the terminal device sends the data other than padding in the MAC PDU stored in the HARQ buffer to the multiplexing and assembly entity, and the multiplexing and assembly entity stores data corresponding to logical channel 4 (LCH4) and logical channel 5 (LCH5). Based on the logical channel priority process, the terminal device generates a MAC PDU for uplink transmission in the multiplexing and assembly entity using the acquired data and the data stored in the multiplexing and assembly entity. In an embodiment of the present application, the data corresponding to LCH5 stored in the multiplexing and assembly entity has the lowest priority, and the dynamic authorization resources are insufficient to accommodate the data in LCH1 and LCH3 excluding padding, the data corresponding to LCH4, and the data corresponding to LCH5; therefore, when the terminal device reassembles the data packet, it only reassembles the data in LCH1 and LCH3 excluding padding, and the data corresponding to LCH4; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembly entity. In other embodiments, if the dynamic authorization resources are sufficient to accommodate the data in LCH1 and LCH3 excluding padding, the data corresponding to LCH4, and the data corresponding to LCH5; then when the terminal device reassembles the data packet, it reassembles the data in LCH1 and LCH3 excluding padding, the data corresponding to LCH4, and the data corresponding to LCH5.

[0089] In this scenario, by instructing the CG configuration to reassemble data packets through the network device, the problem of data loss that may be caused by dynamic authorization overwriting the configuration authorization can be avoided. For example, through the data packet reassembly method provided in the embodiment of the present application, the terminal device can reassemble the data corresponding to the high-priority service or logical channel stored in the HARQ buffer based on the logical channel priority process, so that the data newly transmitted by the terminal device using the dynamic authorization resource includes the data corresponding to the high-priority service or logical channel transmitted by the terminal device using the configuration authorization resource, thereby avoiding data loss and improving data transmission efficiency.

[0090] In other scenarios, for each logical channel, the network device sends a first indication message to the terminal device, where the first indication message is used to determine whether the terminal device reassembles data packets corresponding to the logical channel when transmitting data using dynamic authorization resources scheduled by PDCCH.

[0091] In a specific implementation, the network device may send the first indication information to the terminal device through an RRC message, such as the network device configuring the logical channel configuration (Logical Channel Config) through an RRC reconfiguration message; the Logical Channel Config includes parameters such as the allowedCG-List indicating which configuredGrantConfigs the logical channel is allowed to transmit on, and also includes the first indication information; wherein the first indication information is indication information indicating whether to reorganize the data packet (rebuild MAC PDU).

[0092] If the rebuild MAC PDU is configured to be turned on in the first indication information, it can be determined that after the terminal device transmits data on the configured authorized resources, if the terminal device receives scheduling information for uplink new transmission scheduled by PDCCH encrypted with C-RNTI, the terminal device obtains the information of the logical channel transmitted on the configured authorized resources; the information of the logical channel may be all logical channels transmitted on the configured authorized resources, and the first indication information corresponding to each logical channel; the terminal device determines the first logical channel among all logical channels.

[0093] Among them, the number of the first logical channels can be one or more; the first indication information corresponding to the first logical channel indicates that after the first logical channel is transmitted on the configured authorization resource, the data packets corresponding to the first logical channel are reassembled when transmitted on the dynamic authorization resource; the data transmitted this time using the configured authorization resource includes the data corresponding to the first logical channel; wherein, the data transmitted by the dynamic authorization resource and the data transmitted by the configured authorization resource are for the same HARQ process.

[0094] When performing data packet reassembly, the terminal device can obtain data corresponding to the first logical channel stored in the HARQ buffer. The terminal device sends the obtained data to the multiplexing and assembly entity; the multiplexing and assembly entity generates a MAC PDU for uplink transmission using the obtained data and existing data in the multiplexing and assembly entity. The new MAC PDU is transmitted using dynamic granted resources scheduled by the PDCCH. Data stored in the HARQ buffer other than the data corresponding to the first logical channel may be discarded.

[0095] In the scenario where the first indication information is for a logical channel, another detailed processing flow of data transmission provided by the embodiment of the present application is as follows: Figure 4As shown, the terminal device uses the configured authorized resources to transmit logical channel 1 (LCH1) and logical channel 3 (LCH3), the first indication information corresponding to LCH1 indicates data packet reassembly, and the first indication information corresponding to LCH3 indicates not to reassemble the data packet; the MAC PDU transmitted using the configured authorized resources is stored in the HARQ buffer. During the operation of the configured authorization timer, if the terminal device receives scheduling information for uplink new transmission scheduled by the PDCCH encrypted with C-RNTI from the network device, the terminal device sends the data corresponding to LCH1 stored in the HARQ buffer to the multiplexing and assembly entity, and the multiplexing and assembly entity stores the data corresponding to logical channel 4 (LCH4) and logical channel 5 (LCH5). Based on the logical channel priority process, the terminal device generates a MAC PDU for uplink transmission in the multiplexing and assembly entity using the acquired data corresponding to LCH1 and the data stored in the multiplexing and assembly entity. In an embodiment of the present application, if the dynamic authorization resources are sufficient to accommodate the data corresponding to LCH1, the data corresponding to LCH4, and the data corresponding to LCH5, then when the terminal device reassembles the data packet, the data corresponding to LCH1, the data corresponding to LCH4, and the data corresponding to LCH5 are reassembled. In other embodiments, the data corresponding to LCH5 stored in the multiplexing and assembly entity has the lowest priority, and the dynamic authorization resources are insufficient to accommodate the data corresponding to LCH1, the data corresponding to LCH4, and the data corresponding to LCH5; therefore, when the terminal device reassembles the data packet, only the data corresponding to LCH1 and the data corresponding to LCH4 are reassembled; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembly entity.

[0096] In this scenario, by instructing each logical channel via the network device whether to perform data packet reassembly, the problem of data loss that may be caused by dynamic authorization overwriting the configured authorization can be avoided. For example, through the data packet reassembly method provided in the embodiment of the present application, the terminal device can reassemble the data corresponding to the high-priority service or logical channel stored in the HARQ buffer based on the logical channel priority process, so that the data newly transmitted by the terminal device using the dynamic authorization resource includes the data corresponding to the high-priority logical channel transmitted by the terminal device using the configured authorization resource, thereby avoiding data loss and improving data transmission efficiency. Moreover, by configuring the first indication information corresponding to the logical channel for each logical channel, it is possible to flexibly and accurately control whether to perform data packet reassembly on the data corresponding to the logical channel according to the QoS requirements of the service. Since the terminal device only needs to consider the data corresponding to the logical channel that needs to be retransmitted when performing data packet reassembly, there is no need to reassemble all MAC PDUs stored in the HARQ buffer, thereby avoiding the waste of dynamic authorization resources and improving the efficiency of the use of dynamic authorization resources.

[0097] In some other scenarios, for each MAC PDU, the network device sends a first indication message to the terminal device, where the first indication message is used to determine whether the terminal device reassembles the MAC PDU when transmitting data using dynamic authorization resources scheduled by PDCCH.

[0098] In a specific implementation, the network device may send the first indication information to the terminal device via an RRC message, such as sending the first indication information to the terminal device via an RRC reconfiguration message; wherein the first indication information is used to indicate whether to reassemble data packets for MAC CEs when transmitting data on dynamically authorized resources after transmitting data on the configured authorized resources. Optionally, the first indication information may further indicate identification information of the MAC CEs for reassembling data packets, that is, which MAC CEs are to be reassembled.

[0099] If the rebuild MAC PDU is configured as enabled in the first indication information, it can be determined that after the terminal device transmits data on the configured authorized resources, if the terminal device receives scheduling information for a new uplink transmission scheduled by a PDCCH scrambled using a C-RNTI, the terminal device obtains information about the MAC CE transmitted on the configured authorized resources; the information about the MAC CE may be all MAC CEs transmitted on the configured authorized resources, as well as the first indication information corresponding to each MAC CE. The terminal device determines the first MAC CE among all MAC CEs.

[0100] The number of the first MAC CEs may be one or more; the first indication information corresponding to the first MAC CE indicates that after the first MAC CE is transmitted on the configured authorization resource, the first MAC CE is reassembled into data packets when transmitted on the dynamic authorization resource; the data transmitted this time using the configured authorization resource includes the first MAC CE; the data transmitted by the dynamic authorization resource and the data transmitted by the configured authorization resource are for the same HARQ process.

[0101] When performing data packet reassembly, the terminal device can obtain the first MAC CE stored in the HARQ buffer. The terminal device sends the obtained data to the multiplexing and assembly entity; the multiplexing and assembly entity generates a MAC PDU for uplink transmission using the obtained data and existing data in the multiplexing and assembly entity. The new MAC PDU is transmitted using dynamic granted resources scheduled by the PDCCH. Data stored in the HARQ buffer other than the first MAC CE may be discarded.

[0102] In the scenario where the first indication information is for MAC CE, another detailed processing flow of data transmission provided by the embodiment of the present application is as follows: Figure 5 As shown, the terminal device transmits the first indication information corresponding to the first MAC CE using the configured authorized resources to indicate data packet reassembly; the MAC PDU transmitted using the configured authorized resources is stored in the HARQ buffer. During the operation of the configured authorization timer, if the terminal device receives scheduling information for uplink new transmission scheduled by the PDCCH encrypted with C-RNTI and sent by the network device, the terminal device sends the first MAC CE stored in the HARQ buffer to the multiplexing and assembly entity, in which data corresponding to logical channel 4 (LCH4) and logical channel 5 (LCH5) are stored. Based on the logical channel priority process, the terminal device generates a MAC PDU for uplink transmission in the multiplexing and assembly entity using the acquired data corresponding to LCH1 and the data stored in the multiplexing and assembly entity. In an embodiment of the present application, the data corresponding to LCH5 stored in the multiplexing and assembly entity has the lowest priority, and the dynamically authorized resources are insufficient to accommodate the first MAC CE, the data corresponding to LCH4, and the data corresponding to LCH5; therefore, when the terminal device reassembles the data packet, it only reassembles the first MAC CE and the data corresponding to LCH4; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembly entity. In other embodiments, if the dynamically authorized resources are sufficient to accommodate the first MAC CE, the data corresponding to LCH4, and the data corresponding to LCH5; then, when the terminal device reassembles the data packet, it reassembles the first MAC CE, the data corresponding to LCH4, and the data corresponding to LCH5.

[0103] In this scenario, by instructing each MAC CE on whether to perform data packet reassembly through the network device, the problem of data loss that may be caused by dynamic authorization overwriting the configured authorization can be avoided. For example, through the data packet reassembly method provided in the embodiment of the present application, the terminal device can reassemble the data packets of the high-priority MAC CE stored in the HARQ buffer based on the logical channel priority process, so that the data newly transmitted by the terminal device using the dynamic authorization resource includes the high-priority MAC CE transmitted by the terminal device using the configured authorization resource, thereby avoiding data loss and improving data transmission efficiency. In addition, by configuring the first indication information corresponding to the MAC CE for each MAC CE, it is possible to flexibly and accurately control whether to reassemble the data packet of the MAC CE according to the QoS requirements of the service. Since the terminal device only needs to consider the MAC CE that needs to be retransmitted when performing data packet reassembly, it is not necessary to reassemble all the MAC PDUs stored in the HARQ buffer, thereby avoiding the waste of dynamic authorization resources and improving the efficiency of the use of dynamic authorization resources.

[0104] In some other scenarios, for each logical channel and for each MAC CE, the network device sends a first indication message to the terminal device respectively; the first indication message is used to determine whether the terminal device performs data packet reassembly on the data corresponding to the logical channel and whether to perform data packet reassembly on the MACCE when transmitting data using dynamic authorization resources scheduled by PDCCH.

[0105] For example, the terminal device uses the configured authorized resources to transmit logical channel 1 (LCH1) and logical channel 3 (LCH3), the first indication information corresponding to LCH1 indicates data packet reassembly, and the first indication information corresponding to LCH3 indicates not to reassemble the data packet; the terminal device uses the first indication information corresponding to the first MAC CE transmitted by the configured authorized resources to indicate data packet reassembly, and the first indication information corresponding to the second MAC CE indicates not to reassemble the data packet. If the terminal device receives scheduling information for uplink new transmission scheduled by PDCCH scrambled by C-RNTI from the network device, the terminal device sends the data corresponding to LCH1 stored in the HARQ buffer and the first MAC CE to the multiplexing and assembly entity, in which the data corresponding to logical channel 4 (LCH4) and logical channel 5 (LCH5) are stored. Based on the logical channel priority process, the terminal device generates a MAC PDU for uplink transmission in the multiplexing and assembly entity using the obtained data corresponding to LCH1, the first MAC CE, and the data stored in the multiplexing and assembly entity.

[0106] It should be noted that in the above embodiments of the present application, the HARQ process associated with the uplink new transmission scheduled by the network device is the same as the HARQ process associated with the data transmission on the configured authorized resources. That is, the transmission for dynamic authorization and the transmission for configured authorization correspond to the same HARQ process.

[0107] It should be understood that in the various embodiments of the present application, the size of the serial numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
