Detailed ways

In order to have a more detailed understanding of the characteristics and technical content of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present application.

Before describing the embodiments of the present application in detail, a brief description of related technologies is provided.

Non-terrestrial communication network (Non Terrestrial Network, NTN) uses satellite communication to provide communication services to ground users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's area. For example, general terrestrial communication cannot cover areas where communication equipment cannot be installed, such as oceans, mountains, or deserts, or areas that cannot be covered by communication due to sparse population; while for satellite communication, due to a A satellite can cover a large area of the ground, and the satellite can orbit the earth, so theoretically every corner of the earth can be covered by satellite communications. Secondly, satellite communication has high social value. Satellite communication can be covered at a lower cost in remote mountainous areas, poor and backward countries or regions, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed areas and promoting The development of these areas. Third, the satellite communication distance is long, and the increase of the communication distance will not significantly increase the cost of communication; finally, the stability of satellite communication is high, and it is not restricted by natural disasters.

Communication satellites are divided into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, and highly elliptical satellites according to their orbital heights. Orbit (High Elliptical Orbit, HEO) satellites, etc. The following is a brief description of LEO and GEO respectively.

LEO's orbital altitude ranges from 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between terminal devices is generally less than 20ms. The maximum satellite viewing time is 20 minutes. The signal propagation distance is short, the link loss is small, and the requirement for the transmission power of the terminal equipment is not high.

The orbital height of GEO is 35786km, and the period of rotation around the earth is 24 hours. The signal propagation delay of single-hop communication between terminal devices is generally 250ms. In order to ensure the coverage of satellites and increase 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 tens to hundreds of kilometers in diameter. Ground area.

A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter. Ground area.

The following briefly describes the Hybrid Automatic Repeat reQuest (HARQ) mechanism in the New Radio (NR) system.

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. The retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and supplemented by the retransmission function of the RLC layer. The HARQ mechanism of the MAC layer can provide fast retransmission, and the ARQ mechanism of the RLC layer can provide reliable data transmission.

HARQ uses Stop-and-Wait Protocol to send data. In the stop-and-wait protocol, after the sender sends a Transport Block (TB), it stops data transmission to wait for confirmation. In this way, the sender stops data transmission after each transmission to wait for the confirmation message, 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 sender can use another HARQ process to continue sending data. These HARQ processes together form a HARQ entity, which combines a 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.

Based on the current NR protocol, each serving cell corresponding to a 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 equipment can indicate the maximum number of HARQ processes to the terminal equipment through the semi-static configuration of Radio Resource Control (Radio Resource Control, RRC) signaling according to the network deployment situation. If the network device does not provide corresponding configuration parameters, the default number of HARQ processes in the downlink is 8, and the maximum number of HARQ processes supported by each carrier in the uplink is always 16. Each HARQ process corresponds to a HARQ process identifier (Identifier, ID). For the downlink, the Broadcast Control Channel (BCCH) uses a dedicated broadcast HARQ process. For the uplink, the HARQ ID 0 is used for message 3 (Msg3) transmission in the random process.

For terminal equipment that does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB at the same time; for terminal equipment that supports downlink space division multiplexing, each downlink HARQ process can process 1 or 2 TB at the same time . Each uplink HARQ process of the terminal processes 1 TB at the same time.

HARQ is divided into two types, synchronous and asynchronous in the time domain, and divided into two types, non-adaptive and adaptive in the frequency domain. Both the uplink and downlink of the NR system use an asynchronous adaptive HARQ mechanism. Asynchronous HARQ, that is, retransmission can occur at any time, and the time 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 strategy (Modulation and Coding Scheme, MCS) used for retransmission.

The following briefly describes the logical channel priority (Logical Channel Prioritization, LCP) in the NR system.

Similar to the long term evolution (LTE) system, in the NR system, the network equipment allocates uplink transmission resources based on each terminal device, instead of allocating uplink transmission resources based on each radio bearer. Which radio bearer data can be The transmission into the allocated uplink transmission resources is determined by the terminal equipment.

Based on the uplink transmission resources configured by the network device, the terminal device needs to determine the amount of transmission data for each logical channel in the initial transmission of the MAC protocol data unit (Protocol Data Unit, PDU); in some cases, the terminal device also needs to be the MAC control unit (Control Element, CE) allocates resources. In order to realize the multiplexing of uplink logical channels, each uplink logical channel needs to be assigned a priority. For a given size of MAC PDU, when there are multiple uplink logical channels that have data transmission requirements at the same time, the resources of the MAC PDU are allocated in order of the priority of the logical channel corresponding to each uplink logical channel. . At the same time, in order to take into account the fairness between different logical channels, the concept of Prioritized Bit Rate (PBR) is introduced. When the terminal equipment performs logical channel multiplexing, it is necessary to ensure the minimum data rate requirements of each logical channel. Therefore, it is avoided that because the uplink logical channel with high priority always occupies the uplink resources allocated to the terminal device by the network device, the other low priority uplink logical channels of the terminal device are not allocated uplink resources and are "starved".

The following is a brief description of Configured Grant (CG).

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

The NR system supports the following two types of uplink configuration authorized transmission:

1. Physical Uplink Shared Channel (PUSCH) transmission based on the first type of configuration grant (configured grant Type 1).

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

2. PUSCH transmission based on the second type of configuration authorization (configured grant Type 2).

A two-step resource configuration method is adopted: First, the network equipment homogenous RRC signaling configures the transmission resources and transmission parameters including the period of the time domain resource, the number of repetitions, the frequency hopping, and the number of HARQ processes. Then, the physical downlink control channel (Physical Downlink Control Channel, PDCCH) scrambled by using the Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) to activate the PUSCH transmission based on the second type of configuration authorization, and at the same time Configure other transmission resources and transmission parameters including time domain resources, frequency domain resources, and MCS. When the terminal device receives the RRC configuration parameter, it cannot immediately use the resources and parameters configured by the configuration parameter to perform PUSCH transmission, but must receive the corresponding PDCCH activation and configure other resources and parameters before PUSCH transmission can be performed.

Since the maximum number of HARQ processes supported by the terminal equipment is 16, for each CG configuration, the network equipment configures a limited number of HARQ process numbers for the terminal equipment, and the terminal equipment uses these HARQ process numbers in the CG resource by polling. Uplink transmission. Assuming that the HARQ process ID 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 groups MAC PDU1 at time t0, the MAC PDU1 is stored in HARQ ID i. At time t1, because It is the same as the HARQ process used at t0, even if MAC PDU1 has not been transmitted correctly at this time, MAC PDU1 will be flushed. Therefore, a configured grant timer (configured Grant Timer) is introduced for each HARQ process. The maintenance method of Configured Grant Timer is:

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

In the NR system, after the terminal device uses the CG resource to send the MAC PDU, it starts the CG timer and starts to monitor the PDCCH scrambled by the CS-RNTI and the C-RNTI. The transmitted MAC PDU is stored in the HARQ buffer (buffer). If the terminal equipment receives the C-RNTI scrambled PDCCH for scheduling uplink transmission, no matter what value the New Data Indication (NDI) in the PDCCH takes, the terminal equipment will consider that the NDI has been reversed, and the terminal equipment will start from the multiplexing and assembling entity. (Multiplexing and assembly entity) Obtain the MAC PDU to be transmitted. Moreover, once the transmission is completed on the dynamically scheduled resources, the new MAC PDU will be stored in the HARQ buffer, and the MAC PDU previously transmitted by the CG will be flushed. In this way, the data transmitted by CG will be lost.

Since the CG resource is pre-configured, the network device does not know when the terminal device will perform uplink transmission on the CG resource, unless the network device detects the uplink transmission on the CG resource. In the ground network of the NR system, the propagation delay between the terminal equipment and the network equipment is relatively small, and the network equipment may alleviate the above-mentioned data loss problem to a certain extent through implementation. For example, the network equipment dynamically schedules uplink transmission this year after the uplink transmission detection of each CG resource.

Compared with the cellular network adopted by the traditional NR system, the propagation delay between the terminal equipment and the satellite in NTN is larger, especially in the GEO scenario, the propagation delay is about tens of milliseconds. If the uplink can be dynamically scheduled after the uplink detection of the CG resource each time, it will inevitably cause a relatively large scheduling delay. Therefore, the probability of data loss in NTN scenes is higher.

When implementing data transmission, the applicant found that different services have different Quality of Service (QoS) attributes, such as services that are sensitive to delay or services that are sensitive to transmission reliability. For reliability-sensitive data, if the HARQ buffer of CG transmission must be cleared every time dynamically scheduled resources, the reliability of data transmission will be reduced.

An optional processing procedure of the data packet reassembly method provided in the embodiment of the present application, as shown in FIG. 2, includes the following steps:

Step S201: When the terminal device transmits data on the configured authorized resource and the authorized timer is configured to run, the terminal device receives scheduling information and first indication information for the uplink new transmission; the first indication information is used to determine Whether to carry out data packet reassembly for the transmission of dynamic authorized resources.

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

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

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 data transmission on the configured authorized resource.

In some embodiments, in a case where the first indication information is used to determine to perform data packet reassembly, the method may further include:

In step S202, the terminal device reassembles the data packet through the multiplexing and assembling entity.

In some embodiments, the method may further include:

Step S203: The terminal device uses the dynamic authorized resource in the scheduling information to transmit the reassembled data packet.

For step S201, the first indication information may indicate whether to perform data packet reassembly for the transmission of dynamic authorized resources based on different dimensions. For example, the first indication information is based on the CG indicating whether to perform data packet reassembly for the transmission of dynamic authorized resources; that is, for data transmitted on a certain CG resource, whether to transmit data to the CG resource when using the dynamic authorized resource to transmit data The data is packet reorganized. For example, the first indication information indicates whether to perform data packet reassembly for the transmission of dynamically authorized resources based on the logical channel; that is, for data corresponding to one or more logical channels, after using CG resources for transmission, use the dynamically authorized resource to transmit data When, whether to perform data packet reassembly on the data corresponding to the logical channel. For example, the first indication information is based on the MAC CE indicating whether to perform data packet reassembly for the transmission of dynamic authorized resources; that is, for one or more MAC CEs, after using CG resources for transmission, whether to use dynamic authorized resources to transmit data Perform data packet reassembly on the MAC CE.

The following describes the data packet reassembly method provided in the embodiment of the present application based on the above three different dimensions.

When the terminal device transmits data on the configured authorized resource and the authorized timer is configured to run, the terminal device receives the PDCCH scrambled by the C-RNTI sent by the network device to schedule a new uplink transmission.

In some scenarios, for each CG configuration, the network device sends first indication information to the terminal device. The first indication information is used to determine whether the terminal device transmits data using the dynamic authorized resource scheduled by the PDCCH. Package reorganization.

In specific implementation, the network device may send the first indication information to the terminal device through an RRC message. For example, the network device configures the configured Grant Config through the RRC reconfiguration message; the configured Grant Config includes the uplink resource. In addition to the parameter nrofHARQ-Processes of the number of available HARQ processes, the periodicity parameter that indicates the time interval between uplink authorizations, CS-RNTI, and CG timer, it also includes first indication information; where the first indication information indicates whether Instruction information for rebuild MAC PDU. In terms of network implementation, the logical channel transmission that requires high transmission reliability can be configured on the CG configuration, that is, the allowedCGlist is pointed to the configured Grant config in the LogicalChannelConfig of the logical channel whose transmission reliability meets the first condition.

In a specific implementation, the network device may also send the first indication information by scheduling the terminal device to transmit the first indication information by using the PDCCH of the dynamically authorized resource to transmit data; that is, the first indication information is carried in the PDCCH.

If the rebuild MAC PDU is configured in the on state in the first indication information, it can be determined that after the terminal device transmits data on the configured authorized resource, if the terminal device receives the scheduling information for the new uplink transmission, the terminal device uses the dynamic authorization Before the resource transmits data, data packet reassembly is required; wherein the data transmitted by the dynamically authorized resource and the data transmitted by the configured authorized resource are for the same HARQ process.

During data packet reassembly, the terminal device can obtain data other than padding in the MAC PDU stored in the HARQ buffer; wherein, the data can be data corresponding to each logical channel transmitted on the CG resource And/or MAC CE. The terminal device sends the acquired data to the multiplexing and assembling entity; in the multiplexing and assembling entity, the acquired data and the existing data in the multiplexing and assembling entity are used to generate a MAC PDU for uplink transmission. The new MAC PDU is transmitted using dynamic authorized resources scheduled by the PDCCH.

In the scenario where the first indication information is for configuration authorization, a detailed processing flow of data transmission provided in the embodiment of the present application, as shown in FIG. 3, the terminal device uses the configuration authorization resource to transmit logical channel 1 (LCH1) and logical channel 3(LCH3), the MAC PDU transmitted with the configured authorized resource is stored in the HARQ buffer. During the operation of the configured authorized timer, if the terminal device receives the PDCCH scrambled by the network device from the network device to schedule the new uplink transmission Information and the first indication information, and the first indication information indicates data packet reassembly, the terminal device sends the data except padding in the MAC PDU stored in the HARQ buffer to the multiplexing and assembling entity, and the multiplexing and assembling 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 stores the acquired data in the multiplexing and assembling entity and the multiplexing and assembling entity Generate MAC PDU for uplink transmission. In the embodiment of this application, the priority of the data corresponding to LCH5 stored in the multiplexing and assembling entity is the lowest, and the dynamic authorized resources are not enough to accommodate the data except padding in LCH1 and LCH3, the data corresponding to LCH4, and the data corresponding to LCH5 ; Therefore, when the terminal device reorganizes the data packet, it only reorganizes the data except padding in LCH1 and LCH3 and the data corresponding to LCH4; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembling entity. In other embodiments, if the dynamic authorized resources are sufficient to accommodate the data except padding in LCH1 and LCH3, the data corresponding to LCH4, and the data corresponding to LCH5; when the terminal device reorganizes the data packet, the Data, data corresponding to LCH4, and data corresponding to LCH5 undergo packet reassembly.

In this scenario, the network device instructs the CG configuration to perform data packet reassembly, which can avoid the problem of data loss that may be caused when the dynamic authorization overrides the configuration authorization. For example, through the data packet reorganization method provided by the embodiments of this application, the terminal device can reorganize 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 terminal device uses the dynamic The newly transmitted data of the authorized resource includes the data corresponding to the high-priority service or logical channel transmitted by the terminal device using the configured authorized resource, which avoids data loss and improves the efficiency of data transmission.

In other scenarios, for each logical channel, the network device sends first indication information to the terminal device. The first indication information is used to determine whether the terminal device transmits data using the dynamic authorized resources scheduled by the PDCCH. The data corresponding to the logical channel undergoes data packet reassembly.

In a specific implementation, the network device may send the first indication information to the terminal device through an RRC message, for example, the network device configures a logical channel configuration (Logical Channel Config) through an RRC reconfiguration message; the Logical Channel Config includes an indication that the logical channel is allowed In addition to the allowedCG-List and other parameters transmitted on which configuredGrantConfig, the first indication information is also included; where the first indication information is indication information indicating whether to rebuild the MAC PDU.

If the rebuild MAC PDU is configured in the on state in the first indication information, it can be determined that after the terminal device transmits data on the configured authorized resource, if the terminal device receives the PDCCH scrambled by the C-RNTI to schedule the new uplink scheduling information, Then the terminal device obtains the information of the logical channel transmitted on the configured authorized resource; the information of the logical channel may be all the logical channels transmitted on the configured authorized resource, and the first indication information corresponding to each logical channel; The terminal device determines the first logical channel among all logical channels.

Wherein, the number of the first logical channel may 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 authorized resource , Performing data packet reassembly on the data corresponding to the first logical channel when transmitting on the dynamically authorized resource; the data transmitted using the configured authorized resource this time includes the data corresponding to the first logical channel; wherein, the dynamic authorized resource The transmitted data and the data transmitted by the configured authorized resource are for the same HARQ process.

During the data packet reassembly, the terminal device can obtain the data corresponding to the first logical channel stored in the HARQ buffer. The terminal device sends the acquired data to the multiplexing and assembling entity; in the multiplexing and assembling entity, the acquired data and the existing data in the multiplexing and assembling entity are used to generate a MAC PDU for uplink transmission. The new MAC PDU is transmitted using dynamic authorized resources scheduled by the PDCCH. Wherein, the data stored in the HARQ buffer except for the data corresponding to the first logical channel may be discarded.

In the scenario where the first indication information is for a logical channel, another detailed processing flow of data transmission provided in the embodiment of the present application is shown in FIG. 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 reorganize data packets; the MAC PDU transmitted with the configured authorized resource is stored in the HARQ buffer. During the operation of the configured authorization timer, if the terminal device receives the PDCCH scrambled by the C-RNTI sent by the network device to schedule the new uplink scheduling information, the terminal device sends the data corresponding to LCH1 stored in the HARQ buffer to the multiplexer And the assembling entity, the multiplexing and assembling entity stores logical channel 4 (LCH4) and logical channel 5 (LCH5) corresponding data, the terminal equipment based on the logical channel priority process, the multiplexing and assembling entity will obtain The data corresponding to the LCH1 and the data stored in the multiplexing and assembling entity generate a MAC PDU for uplink transmission. In the embodiment of this application, if the dynamically authorized resources are sufficient to accommodate the data corresponding to LCH1, the data corresponding to LCH4, and the data corresponding to LCH5; when the terminal device reorganizes the data packet, the data corresponding to LCH1, the data corresponding to LCH4, and the data corresponding to LCH5 The data undergoes packet reassembly. In other embodiments, the data corresponding to LCH5 stored in the multiplexing and assembling entity has the lowest priority, and the dynamic authorized resources are insufficient to accommodate the data corresponding to LCH1, the data corresponding to LCH4, and the data corresponding to LCH5; therefore, the terminal device When reassembling data packets, only the data corresponding to LCH1 and the data corresponding to LCH4 are reorganized; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembling entity.

In this scenario, the network device instructs each logical channel whether to perform data packet reassembly, which can avoid the problem of data loss that may be caused when the dynamic authorization overrides the configuration authorization. For example, through the data packet reorganization method provided by the embodiments of this application, the terminal device can reorganize 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 terminal device uses the dynamic The newly transmitted data of the authorized resource includes the data corresponding to the logical channel with high priority transmitted by the terminal device using the configured authorized resource, which avoids data loss and improves the efficiency of data transmission. In addition, 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 reorganizing the data packet, it does not need to reorganize all MAC PDUs stored in the HARQ buffer, avoiding wasting dynamic authorization resources and improving the use efficiency of dynamic authorization resources.

In some other scenarios, for each MAC PDU, the network device sends first indication information to the terminal device. The first indication information is used to determine whether the terminal device transmits data using the dynamic authorized resource scheduled by the PDCCH. MAC PDU carries out data packet reassembly.

In specific implementation, the network device may send the first indication information to the terminal device through an RRC message. For example, the network device may send the first indication information to the terminal device through an RRC reconfiguration message; wherein, the first indication information is used to indicate the configuration After the data is transmitted on the authorized resource, whether to perform data packet reassembly on the MAC CE when transmitting on the dynamic authorized resource. Optionally, the first indication information may also indicate the identification information of the MAC CE of the reassembled data packet, that is, which MAC CE is to be reassembled for the data packet.

If the rebuild MAC PDU is configured in the on state in the first indication information, it can be determined that after the terminal device transmits data on the configured authorized resource, if the terminal device receives the PDCCH scrambled by the C-RNTI to schedule the new uplink scheduling information, Then the terminal device obtains the MAC CE information transmitted on the configured authorized resource; the MAC CE information may be all MAC CEs transmitted on the configured authorized resource and the first indication information corresponding to each MAC CE. The terminal device determines the first MAC CE among all MAC CEs.

The number of the first MAC CE may be one or multiple; the first indication information corresponding to the first MAC CE indicates that after the first MAC CE is transmitted on the configured authorized resource , Perform data packet reassembly on the first MAC CE when transmitting on the dynamic authorized resource; the data transmitted using the configured authorized resource this time includes the first MAC CE; wherein, the data transmitted by the dynamic authorized resource is the same as the The data transmitted by configuring authorized resources is for the same HARQ process.

When performing data packet reassembly, the terminal device can obtain the first MAC CE stored in the HARQ buffer. The terminal device sends the acquired data to the multiplexing and assembling entity; in the multiplexing and assembling entity, the acquired data and the existing data in the multiplexing and assembling entity are used to generate a MAC PDU for uplink transmission. The new MAC PDU is transmitted using dynamic authorized resources scheduled by the PDCCH. Among them, all data stored in the HARQ buffer except for the first MAC CE may be discarded.

In the scenario where the first indication information is for MAC CE, another detailed processing flow of data transmission provided in the embodiment of this application is shown in Figure 5, the terminal device uses the configured authorized resource to transmit the first MAC CE corresponding to the first The indication information indicates data packet reassembly; the MAC PDU transmitted with the configured authorized resource is stored in the HARQ buffer. During the operation of the configured authorization timer, if the terminal device receives the PDCCH scrambled by the C-RNTI from the network device to schedule the new uplink scheduling information, the terminal device sends the first MAC CE stored in the HARQ buffer to the multiplexer And the assembling entity, the multiplexing and assembling entity stores logical channel 4 (LCH4) and logical channel 5 (LCH5) corresponding data, the terminal equipment based on the logical channel priority process, the multiplexing and assembling entity will obtain The data corresponding to the LCH1 and the data stored in the multiplexing and assembling entity generate a MAC PDU for uplink transmission. In the embodiment of this application, the priority of the data corresponding to LCH5 stored in the multiplexing and assembling entity is the lowest, and the dynamic authorized resources are not enough to accommodate the first MAC CE, the data corresponding to LCH4, and the data corresponding to LCH5; therefore, the terminal equipment When reassembling data packets, only the first MAC CE and the data corresponding to LCH4 are reorganized; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembling entity. In other embodiments, if the dynamic authorized resources are sufficient to accommodate the first MAC CE, the data corresponding to LCH4, and the data corresponding to LCH5; when the terminal device reorganizes the data packet, the data corresponding to the first MAC CE, LCH4 and the data corresponding to LCH5 The data undergoes packet reassembly.

In this scenario, the network device instructs each MAC CE whether to perform data packet reassembly, which can avoid the problem of data loss that may be caused when the dynamic authorization overrides the configuration authorization. For example, through the data packet reorganization method provided by the embodiments of this application, the terminal device can reorganize the MAC CE stored in the HARQ buffer with the high priority MAC CE stored in the HARQ buffer based on the logical channel priority process, so that the terminal device uses the dynamic authorized resource to transmit the newly transmitted data. The data includes the MAC CE with a high priority for transmission by the terminal device using the configured authorized resource, which avoids data loss and improves the efficiency of data transmission. 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 perform data packet reassembly on 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 reorganizing the data packet, it does not need to reorganize all MAC PDUs stored in the HARQ buffer, avoiding wasting dynamic authorization resources and improving the use efficiency of dynamic authorization resources.

In still other scenarios, for each logical channel and for each MAC CE, the network device sends first indication information to the terminal device; the first indication information is used to determine that the terminal device is using the PDCCH scheduled dynamic authorization resource transmission In the case of data, whether to perform packet reassembly on the data corresponding to the logical channel, and whether to perform packet reassembly on MAC CE.

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 reorganize data packets. The terminal device uses the first indication information corresponding to the first MAC CE configured to transmit the authorized resource 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 the PDCCH scrambled by C-RNTI sent by the network device to schedule the new uplink scheduling information, the terminal device sends the data corresponding to LCH1 and the first MAC CE stored in the HARQ buffer to the multiplexing and assembling entity The data corresponding to logical channel 4 (LCH4) and logical channel 5 (LCH5) are stored in the multiplexing and assembling entity. Based on the logical channel priority process, the terminal equipment corresponds to the acquired LCH1 in the multiplexing and assembling entity The data stored in the first MAC CE, and the data stored in the multiplexing and assembling entity generate a MAC PDU for uplink transmission.
