Detailed Description

So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

Before describing embodiments of the present application in detail, a brief description of related art will be provided.

A Non-Terrestrial communication Network (NTN) provides communication services to Terrestrial users by means of satellite communication. Satellite communications have many unique advantages over terrestrial cellular communications. Firstly, satellite communication is not limited by user regions, for example, general land communication can not cover regions where communication equipment can not be set up, such as oceans, mountains and deserts, or communication coverage is not made due to sparse population; for satellite communication, since one satellite can cover a large area of ground and the satellite can orbit the earth, theoretically every corner of the earth can be covered by satellite communication. Secondly, satellite communication has higher social value. Satellite communication can be covered in remote mountainous areas, poor and laggard countries or areas with lower cost, so that people in the areas can enjoy advanced voice communication and mobile internet technology, the digital gap between the areas is favorably reduced and developed, and the development of the areas is promoted. Thirdly, the satellite communication distance is long, and the communication cost cannot be obviously increased due to the increase of the communication distance; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, geosynchronous Orbit (GEO) satellites, High-elliptic Orbit (HEO) satellites, and the like according to the difference in orbital height. The LEO and GEO are briefly described below, respectively.

The LEO has a track height in the range of 500km to 1500km, corresponding to a track period of about 1.5 hours to 2 hours. The signal propagation delay for single hop communication between terminal devices is typically less than 20 ms. Maximum satellite visibility time 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the terminal equipment is not high.

The GEO had an orbital height of 35786km and a period of 24 hours of rotation around the earth. The signal propagation delay for single hop communication between terminal devices is typically 250 ms. In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form dozens of or even hundreds of beams to cover the ground; one satellite beam may cover a ground area several tens to hundreds of kilometers in diameter.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form dozens of or even hundreds of beams to cover the ground; one satellite beam may cover a ground area several tens to hundreds of kilometers in diameter.

A Hybrid Automatic Repeat reQuest (HARQ) mechanism in a New Radio (NR) system is briefly described below.

The NR system includes a two-stage retransmission mechanism: a HARQ mechanism of a Media Access Control (MAC) layer and an Automatic Repeat reQuest (ARQ) mechanism of a Radio Link Control (RLC) layer. Retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and is 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 a Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the standby protocol, after a sender sends a Transport Block (TB), data transmission is stopped to wait for an acknowledgement. Thus, the sending end stops data transmission after each transmission to wait for the acknowledgement information, which results in low user throughput. Therefore, the NR system uses a plurality of parallel HARQ processes, and when one HARQ process is waiting for acknowledgement information, the transmitting end can continue to transmit data using another HARQ process. These HARQ processes together constitute a HARQ entity that incorporates a stop-and-wait protocol, allowing for continuous transmission of data. HARQ has a difference between uplink HARQ and downlink HARQ. Uplink HARQ is for uplink data transmission and downlink HARQ is for downlink data transmission. The uplink HARQ and the downlink HARQ are independent.

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

For terminal equipment which does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB simultaneously; for a terminal device supporting downlink space division multiplexing, each downlink HARQ process may process 1 or 2 TBs simultaneously. Each uplink HARQ process of the terminal processes 1 TB simultaneously.

HARQ is classified into two types, synchronous and asynchronous, in the time domain, and non-adaptive and adaptive, in the frequency domain. The uplink and the downlink of the NR system use an asynchronous adaptive HARQ mechanism. Asynchronous HARQ, i.e. retransmission, can occur at any time, and the time interval between the retransmission of the same TB and the last transmission is not fixed. Adaptive HARQ may change the frequency domain resources and Modulation and Coding Scheme (MCS) used for retransmission.

Logical Channel Priority (LCP) in the NR system is briefly described below.

As in the Long Term Evolution (LTE) system, in the NR system, the network device allocates uplink transmission resources on a per terminal device basis, instead of allocating uplink transmission resources on a per radio bearer basis, and it is determined by the terminal device which radio bearers can put data into the allocated uplink transmission resources for transmission.

Based on the uplink transmission resource configured by the network device, the terminal device needs to determine the transmission Data volume of each logical channel in the initial transmission MAC Protocol Data Unit (PDU); in some cases, the terminal device also allocates resources for a MAC Control Element (CE). In order to realize multiplexing of uplink logical channels, a priority needs to be allocated to each uplink logical channel. For a MAC PDU with a given size, under the condition that a plurality of uplink logical channels have data transmission requirements at the same time, resources of the MAC PDU are sequentially distributed according to the descending order of the logical channel priority corresponding to each uplink logical channel. Meanwhile, in order to take fairness among different logical channels into account, a concept of Prioritized Bit Rate (PBR) is introduced, and when a terminal device multiplexes logical channels, it is necessary to first ensure a minimum data Rate requirement of each logical channel, so as to avoid that uplink logical channels with high priority always occupy uplink resources allocated to the terminal device by a network device, and therefore, other uplink logical channels with low priority are not allocated with uplink resources and are "starved".

A brief description of the Configuration Grant (CG) is provided below.

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

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

1. and transmitting a Physical Uplink Shared Channel (PUSCH) based on a first Type of configuration grant (configured grant Type 1).

The network device configures all transmission resources and transmission parameters including time domain resources, frequency domain resources, time domain resource periods, MCS, repetition times, frequency hopping, HARQ process number and the like through RRC signaling. After receiving the RRC configuration parameter, the terminal device may immediately use the configured transmission parameter to perform PUSCH transmission on the configured time-frequency resource.

2. PUSCH transmission based on a second Type of configuration grant (configured grant Type 2).

A two-step resource allocation mode is adopted: firstly, the network device configures the transmission resources and transmission parameters including the period of time domain resources, the number of repetitions, frequency hopping, and the number of HARQ processes, etc. by homogeneous RRC signaling. Then, a Physical Downlink Control Channel (PDCCH) scrambled by using a Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) activates PUSCH transmission authorized based on the second type of configuration, and simultaneously configures other transmission resources and transmission parameters including time domain resources, frequency domain resources, MCS, and the like. When receiving the RRC configuration parameters, the terminal device cannot immediately use the resources and parameters configured by the configuration parameters to perform PUSCH transmission, and must perform PUSCH transmission after receiving corresponding PDCCH activation and configuring other resources and parameters.

Because 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 resources. Assuming 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, after the terminal equipment packages the MAC PDU1 at time t0, the MAC PDU1 is stored in the HARQ ID i, and by time t1, since the HARQ process used at time t0 is the same, even though the MAC PDU1 has not been correctly transmitted at this time, the MAC PDU1 is discarded (flush). Therefore, a configured Grant Timer (configured Grant Timer) is introduced for each HARQ process. The maintenance mode of the Configured Grant Timer is as follows:

if the terminal device performs uplink transmission on the resource scheduled by the PDCCH, and the HARQ process used for the uplink transmission can be used for configuring the authorized transmission, the terminal device starts or restarts a configured Grant Timer corresponding to the HARQ process. And if the terminal equipment carries out uplink transmission on the configured authorized resources, the terminal equipment starts or restarts a 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 operating configured Grant Timer. Before the configured Grant Timer corresponding to a certain HARQ process is overtime, the MAC PDU stored in the HARQ process cannot be flushed.

In the NR system, after the terminal equipment sends the MAC PDU by using CG resources, a CG timer is started, and monitoring of PDCCH scrambled by CS-RNTI and C-RNTI is started. The transmitted MAC PDU is stored in the HARQ buffer (buffer). If the terminal equipment receives the PDCCH (physical downlink control channel) scrambled by the C-RNTI (radio network temporary identifier) to schedule uplink transmission, the terminal equipment considers that the New Data Indication (NDI) in the PDCCH is inverted no matter what value the NDI takes, and the terminal equipment obtains the MAC PDU to be transmitted from a Multiplexing and assembling entity (Multiplexing and assembling entity). And, once transmission is completed on the dynamically scheduled resource, a new MAC PDU will be stored in the HARQ buffer, and the MAC PDU transmitted by the CG will be flushed. This can result in the data transmitted by the CG being lost.

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

Compared with a cellular network adopted by a traditional NR system, the propagation delay between terminal equipment and a satellite in the NTN is large, and particularly in a GEO scene, the propagation delay is about tens of milliseconds. If the uplink is dynamically scheduled after the CG resource uplink detection is waited each time, a large scheduling delay will be caused. The probability of NTN scene data loss is high.

When implementing data transmission, the applicant finds that different services have different Quality of Service (QoS) attributes, such as delay-sensitive services or transmission reliability-sensitive services. For data with sensitive reliability, if the resource dynamically scheduled each time needs to clear the HARQ buffer transmitted by CG, the reliability of data transmission will be reduced.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a global system for mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), an LTE system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an LTE-advanced long term evolution (LTE-A) system, a New Radio (NR) system, an evolution system of an NR system, an evolution system of an unlicensed system, an LTE-based access to an unlicensed system, an LTE-based mobile communication (NR-U) system, an NR-based access to a unlicensed system, an UMTS-universal mobile access (UMTS-universal mobile access, a UMTS) system, WiMAX) communication system, Wireless Local Area Networks (WLANs), wireless fidelity (WiFi), next generation communication systems, or other communication systems.

An optional processing flow 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, terminal equipment transmits data on a configuration authorization resource, and receives scheduling information and first indication information aiming at uplink new transmission under the condition that a configuration authorization timer runs; the first indication information is used for determining whether to perform data packet reassembly for transmission of the dynamic grant resource.

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.

In some embodiments, the scheduling information for uplink new transmission includes: and scheduling the uplink newly transmitted scheduling information 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 transmitting data on the configured granted resource.

In some embodiments, in a case that the first indication information is used for determining to perform packet reassembly, the method may further include:

step S202, the terminal device reassembles the data packet by multiplexing and assembling the entities.

In some embodiments, the method may further comprise:

step S203, the terminal device transmits the reassembled data packet by using the dynamic authorized resource in the scheduling information.

For step S201, the first indication information may indicate whether to perform packet reassembly for transmission of the dynamic grant resource based on different dimensions. Such as: the first indication information indicates whether to perform packet reassembly for transmission of the dynamic grant resource based on the CG; that is, whether to perform packet reassembly on data transmitted on a CG resource when transmitting data using a dynamic grant resource for data transmitted on a resource of a CG. Such as: the first indication information indicates whether to perform data packet reassembly for transmission of the dynamic grant resources based on a logical channel; namely, for data corresponding to one or more logical channels, after CG resources are used for transmission, when data transmission of dynamic authorization resources is used, whether data packet reassembly is performed on the data corresponding to the logical channels is performed. Such as: the first indication information indicates whether to perform data packet reassembly for transmission of the dynamic grant resource based on the MAC CE; that is, for one or more MAC CEs, after CG resource transmission, when data transmission of dynamic grant resources is used, whether to perform data packet reassembly on the MAC CE is determined.

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

And the terminal equipment receives the PDCCH (physical downlink control channel) scheduling uplink new transmission scrambled by the C-RNTI (radio network temporary identifier) sent by the network equipment under the condition that the terminal equipment transmits data on the configured authorization resource and the configured authorization timer runs.

In some scenarios, for each CG configuration, a network device sends first indication information to a terminal device, where the first indication information is used to determine whether to perform packet reassembly when the terminal device transmits data using a dynamic grant resource scheduled by a PDCCH.

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 an authorization configuration (configured Grant configuration) through an RRC reconfiguration message; the configured Grant Config comprises parameters such as nrofHARQ-Processes parameter representing the number of HARQ Processes available for the uplink resource, a periodicity parameter representing the time interval between uplink grants, CS-RNTI, CG timer and the like, and also comprises first indication information; wherein the first indication information is indication information indicating whether to reassemble a data packet (rebuild MAC PDU). In terms of network implementation, the logical channel transmission with high requirement on transmission reliability may be configured in the CG configuration, that is, an allowedCGlist is pointed to the configured Grant configuration in the logical channelconfiguration of the logical channel whose transmission reliability satisfies the first condition.

In specific implementation, the network device may further send the first indication information through a PDCCH for scheduling the terminal device to transmit data using the dynamic grant resource; namely, the first indication information is carried in the PDCCH.

If the reconfigured MAC PDU is configured in the first indication information to be in an open state, it can be determined that after the terminal equipment transmits data on the configured authorized resource, if the terminal equipment receives the scheduling information for uplink new transmission, the terminal equipment needs to perform data packet reassembly before transmitting data by using the dynamic authorized resource; wherein, the data transmitted by the dynamic authorized resource and the data transmitted by the configured authorized resource are directed to the same HARQ process.

When the data packet is reassembled, the terminal device may obtain data, except padding information (padding), in the MAC PDU stored in the HARQ buffer; the data may be data and/or MAC CE corresponding to each logical channel transmitted on the CG resource. The terminal equipment sends the acquired data to a multiplexing and assembling entity; and generating the acquired data and the existing data in the multiplexing and assembling entity into MAC PDU for uplink transmission in the multiplexing and assembling entity. The new MAC PDU is transmitted using the PDCCH scheduled dynamic grant resource.

In a scenario that the first indication information is for configuration grant, as shown in fig. 3, the terminal device transmits logical channel 1(LCH1) and logical channel 3(LCH3) by using configuration grant resources, stores MAC PDU transmitted by using configuration grant resources in an HARQ buffer, and during operation of the configuration grant timer, if the terminal device receives scheduling information and the first indication information for uplink new transmission scheduled by using PDCCH scrambled by C-RNTI sent by the network device and the first indication information indicates packet reassembly, the terminal device sends data other than padding in the MAC PDU stored in the HARQ buffer to a multiplexing and assembling entity, where data corresponding to logical channel 4(LCH4) and logical channel 5(LCH5) are stored, and the terminal device is based on a logical channel priority process, generating, in a multiplexing and assembling entity, the acquired data and data stored in the multiplexing and assembling entity into a MAC PDU for uplink transmission. In the embodiment of the application, the data corresponding to the LCH5 stored in the multiplexing and assembling entity has the lowest priority, and the dynamically granted resources are not enough to accommodate the data except padding in the LCH1 and LCH3, the data corresponding to the LCH4 and the data corresponding to the LCH 5; therefore, when the terminal equipment reassembles the data packet, only the data except padding in the LCH1 and the LCH3 and the data corresponding to the LCH4 are reassembled; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembly entity. In other embodiments, if the dynamically granted resources are sufficient to accommodate data in LCH1 and LCH3 other than padding, data corresponding to LCH4, and data corresponding to LCH 5; when the terminal device reassembles the data packet, data except padding in the LCH1 and LCH3, data corresponding to LCH4 and data corresponding to LCH5 are reassembled.

In this scenario, the network device instructs the CG configuration to perform packet reassembly, so that the problem of data loss that may be caused when the dynamic authorization covers the configuration authorization can be avoided. For example, according to the data packet reassembly method provided in the embodiment of the present application, the terminal device can perform data packet reassembly on a service with a high priority stored in the HARQ buffer or data corresponding to the logical channel, so that the data newly transmitted by the terminal device using the dynamic authorized resource includes the service with a high priority transmitted by the terminal device using the configured authorized resource or the data corresponding to the logical channel, thereby avoiding data loss and improving data transmission efficiency.

In other scenarios, for each logical channel, the network device sends first indication information to the terminal device, where the first indication information is used to determine whether to perform packet reassembly on data corresponding to the logical channel when the terminal device transmits data using a dynamic grant resource scheduled by a PDCCH.

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 a Logical Channel configuration (Logical Channel configuration) through an RRC reconfiguration message; the Logical Channel Config comprises parameters such as allowedCG-List which indicates the Logical Channel allows transmission on which configurable GrantConfig, and also comprises first indication information; wherein the first indication information is indication information indicating whether to reassemble a data packet (rebuild MAC PDU).

If the reconfigured MAC PDU is configured in the first indication information to be in an open state, after the terminal equipment is determined to transmit data on the configured authorized resource, if the terminal equipment receives the PDCCH scrambled by the C-RNTI to schedule uplink newly transmitted scheduling information, the terminal equipment acquires the information of the logical channel transmitted on the configured authorized resource; the information of the logical channels may be all logical channels transmitted on the configured authorized resource and first indication information corresponding to each logical channel; the terminal device determines a first logical channel among all logical channels.

The number of the first logical channels may be one or multiple; the first indication information corresponding to the first logical channel indicates that data packet reassembly is performed on data corresponding to the first logical channel when the data packet is transmitted on the dynamic authorized resource after the first logical channel is transmitted on the configuration authorized resource; the data transmitted by using the configuration authorization resource comprises data corresponding to the first logic channel; wherein, the data transmitted by the dynamic authorized resource and the data transmitted by the configured authorized resource are directed to the same HARQ process.

When the data packet is reassembled, the terminal device may obtain data corresponding to the first logical channel stored in the HARQ buffer. The terminal equipment sends the acquired data to a multiplexing and assembling entity; and generating the acquired data and the existing data in the multiplexing and assembling entity into MAC PDU for uplink transmission in the multiplexing and assembling entity. The new MAC PDU is transmitted using the PDCCH scheduled dynamic grant resource. And discarding the data stored in the HARQ buffer except the data corresponding to the first logical channel.

In a scenario that the first indication information is for a logical channel, as shown in fig. 4, the terminal device transmits a logical channel 1(LCH1) and a logical channel 3(LCH3) by using a configuration authorized resource, where the first indication information corresponding to the LCH1 indicates packet reassembly, and the first indication information corresponding to the LCH3 indicates not to reassemble a packet; the MAC PDUs transmitted with the configuration grant resources are stored in the HARQ buffer. During the operation of the configuration authorization timer, if the terminal device receives scheduling information which is sent by the network device and is scheduled by using a PDCCH scrambled by a C-RNTI and newly transmitted in an uplink, the terminal device sends data corresponding to LCH1 stored in the HARQ buffer to a multiplexing and assembling entity, the multiplexing and assembling entity stores data corresponding to logical channel 4(LCH4) and logical channel 5(LCH5), and the terminal device generates MAC PDUs for uplink transmission from the acquired data corresponding to LCH1 and the data stored in the multiplexing and assembling entity based on a logical channel priority process. In the embodiment of the present application, if the dynamically granted resources are sufficient to accommodate the data corresponding to LCH1, the data corresponding to LCH4, and the data corresponding to LCH 5; when the terminal device reassembles the data packet, the data corresponding to the LCH1, the data corresponding to the LCH4, and the data corresponding to the LCH5 are reassembled. In other embodiments, the data corresponding to LCH5 stored in the multiplexing and assembly entity is of lowest priority and the dynamically granted resources are insufficient to accommodate data corresponding to LCH1, data corresponding to LCH4, and data corresponding to LCH 5; therefore, when the terminal device reassembles the data packet, only the data corresponding to the LCH1 and the data corresponding to the LCH4 are reassembled; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembly entity.

In this scenario, the network device indicates whether each logical channel performs packet reassembly, so that a data loss problem possibly caused by dynamic authorization coverage configuration authorization can be avoided. According to the data packet reassembly method provided by the embodiment of the application, the terminal device can perform data packet reassembly on the service with the high priority stored in the HARQ buffer or the data corresponding to the logical channel based on the logical channel priority process, so that the newly transmitted data by the terminal device using the dynamic authorized resource includes the data corresponding to the logical channel with the high priority transmitted by the terminal device using the configured authorized resource, data loss is avoided, and the data transmission efficiency is improved. And, by configuring the first indication information corresponding to each logical channel, whether to perform data packet reassembly on the data corresponding to the logical channel can be flexibly and accurately controlled according to the QoS requirement of the service. When the terminal equipment carries out data packet recombination, only the data corresponding to the logical channel needing to be retransmitted need to be considered, and all MAC PDUs stored in the HARQ buffer do not need to be recombined, so that the waste of dynamic authorization resources is avoided, and the use efficiency of the dynamic authorization resources is improved.

In some scenarios, for each MAC PDU, 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 packet reassembly on the MAC PDU when transmitting data using a dynamic grant resource scheduled by a PDCCH.

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 sends the first indication information to the terminal device through an RRC reconfiguration message; the first indication information is used for indicating whether to perform data packet reassembly on the MAC CE during transmission on the dynamic grant resource after the data is transmitted on the configuration grant resource. Optionally, the first indication information may also indicate identification information of the MAC CE that reassembles the data packet, that is, which MAC CEs are subjected to data packet reassembly.

If the configured rebuild MAC PDU is in an open state in the first indication information, after the terminal equipment is determined to transmit data on the configured authorized resource, if the terminal equipment receives the PDCCH scrambled by the C-RNTI to schedule uplink newly transmitted scheduling information, the terminal equipment acquires the information of the MAC CE transmitted on the configured authorized resource; the information of the MAC CE may be all MAC CEs transmitted on the configured authorized resource and first indication information corresponding to each MAC CE. The terminal device determines a first MAC CE among all the MAC CEs.

Wherein, the number of the first MAC CE 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 authorized resource, the first MAC CE is subjected to data packet reassembly when the first MAC CE is transmitted on a dynamic authorized resource; the data transmitted by using the configuration authorization resource comprises the first MAC CE; wherein, the data transmitted by the dynamic authorized resource and the data transmitted by the configured authorized resource are directed to the same HARQ process.

When performing packet reassembly, the terminal device may obtain the first MAC CE stored in the HARQ buffer. The terminal equipment sends the acquired data to a multiplexing and assembling entity; and generating the acquired data and the existing data in the multiplexing and assembling entity into MAC PDU for uplink transmission in the multiplexing and assembling entity. The new MAC PDU is transmitted using the PDCCH scheduled dynamic grant resource. And discarding the data stored in the HARQ buffer except the first MAC CE.

In a scenario where the first indication information is for the MAC CE, in yet another detailed processing flow of data transmission provided in the embodiment of the present application, as shown in fig. 5, the terminal device transmits, by using the configuration authorization resource, the first indication information indicating data packet reassembly corresponding to the first MAC CE; the MAC PDUs transmitted with the configuration grant resources are stored in the HARQ buffer. During the operation of the configuration authorization timer, if the terminal device receives scheduling information which is transmitted by the network device and is scheduled by using a PDCCH scrambled by a C-RNTI for uplink new transmission, the terminal device transmits a first MAC CE stored in a HARQ buffer to a multiplexing and assembling entity, data corresponding to a logical channel 4(LCH4) and a logical channel 5(LCH5) are stored in the multiplexing and assembling entity, and the terminal device generates MAC PDUs used for uplink transmission from the acquired data corresponding to the LCH1 and the data stored in the multiplexing and assembling entity based on a logical channel priority process. In the embodiment of the present application, the data corresponding to the LCH5 stored in the multiplexing and assembling entity has the lowest priority, and the dynamically granted resources are not sufficient to accommodate the data corresponding to the first MAC CE, the LCH4, and the LCH 5; therefore, when the terminal device reassembles the data packet, only the data corresponding to the first MAC CE and the LCH4 are reassembled; the data corresponding to LCH5 will continue to be stored in the multiplexing and assembly entity. In other embodiments, if the dynamically granted resources are sufficient to accommodate the first MAC CE, the data corresponding to LCH4, and the data corresponding to LCH 5; when the terminal device reassembles the data packet, the data packet reassembly is performed on the data corresponding to the first MAC CE and the LCH4 and the data corresponding to the LCH 5.

In this scenario, the network device indicates whether each MAC CE performs packet reassembly, so that a data loss problem that may be caused when the dynamic authorization coverage configuration is authorized can be avoided. According to the data packet reassembly method provided by the embodiment of the application, the terminal device can perform data packet reassembly on the MAC CE with the high priority stored in the HARQ buffer based on the logical channel priority process, so that the newly transmitted data by the terminal device using the dynamic authorized resource comprises the MAC CE with the high priority transmitted by the terminal device using the configured authorized resource, data loss is avoided, and the data transmission efficiency is improved. And, by configuring the first indication information corresponding to each MAC CE, whether to perform packet reassembly on the MAC CE can be flexibly and accurately controlled according to the QoS requirement of the service. When the terminal equipment recombines the data packet, only the MAC CE needing to be retransmitted needs to be considered, and all MAC PDUs stored in the HARQ buffer do not need to be recombined, so that the waste of dynamic authorization resources is avoided, and the use efficiency of the dynamic authorization resources is improved.

In still other scenarios, the network device sends first indication information to the terminal device for each logical channel and for each MAC CE, respectively; the first indication information is used for determining whether to perform data packet reassembly on data corresponding to the logical channel and whether to perform data packet reassembly on the MAC CE under the condition that the terminal device transmits data by using the dynamic grant resource scheduled by the PDCCH.

For example, the terminal device transmits logical channel 1(LCH1) and logical channel 3(LCH3) by using the allocated grant resources, the first indication information corresponding to LCH1 indicates packet reassembly, and the first indication information corresponding to LCH3 indicates that no packet reassembly is performed; the terminal equipment indicates data packet recombination by using first indication information corresponding to a first MAC CE which is transmitted by using the configuration authorized resource, and indicates that the data packet is not recombined by using first indication information corresponding to a second MAC CE. If the terminal equipment receives scheduling information which is transmitted by the network equipment and is scrambled by using the C-RNTI to schedule uplink new transmission, the terminal equipment transmits data corresponding to LCH1 and first MAC CE stored in the HARQ buffer to a multiplexing and assembling entity, data corresponding to a logical channel 4(LCH4) and a logical channel 5(LCH5) are stored in the multiplexing and assembling entity, and the terminal equipment generates MAC PDU for uplink transmission from the acquired data corresponding to the LCH1, the first MAC CE and the data stored in the multiplexing and assembling entity on the basis of a logical channel priority process.

It should be noted that, in the foregoing 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 data transmission on the configured authorized resource. I.e. the transmission for the dynamic grant corresponds to the same HARQ process as the transmission for the configured grant.

It should be understood that, in the various embodiments of the present application, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
