Background technique

In the fifth generation mobile communication (5th ^Generation , 5G) system, the wireless protocol stack includes the following protocol layers: service data adaptation protocol (service data adaptation protocol, SDAP) layer, packet data convergence protocol (packet data convergence protocol, PDCP) layer layers, a radio link control (radio link control, RLC) layer, a medium access control (medium access control, MAC) layer, and a physical (physical, PHY) layer.

The sender processes data differently at different protocol layers. For example, the main processing of data at the SDAP layer includes: the mapping of quality of service (QoS) flows to the data radio bearer (DRB); the main processing of data at the PDCP layer includes: encryption, integrity protection, Header compression, adding packet data convergence protocol sequence number (packet data convergence protocol sequence number, PDCP SN), etc.; when the data is in the RLC layer, the main processing in the acknowledged mode (acknowledged mode, AM) includes: automatic retransmission request (automatic repeat request, ARQ), segmentation, reassembly, adding radio link control sequence number (radio link control sequence number, RLC SN), for unacknowledged mode (unacknowledged mode, UM) The main processing includes: segmentation, reassembly, Add RLC SN; the main processing of data at the MAC layer includes multiplexing of logical channels and hybrid automatic repeat request (HARQ).

The sender processes the data in the order of SDAP->PDCP->RLC->MAC->PHY, and finally sends it to the receiver by the PHY layer. It can be seen that the sender performs the above-mentioned processing on each data in each protocol layer, which results in a high complexity of the sender's processing.

In a first aspect, the present application provides a data processing method. In this method, when the first condition is satisfied, the sending end performs the first cascade processing on the plurality of data, obtains the first data, and sends the first data. Wherein, a plurality of data belong to one data radio bearer DRB of the transmitting end. The first condition includes one or more of the following: the timer expires, the timer is used to control the above-mentioned first cascade processing, and the timer is started after the previous cascade processing of the above-mentioned first cascade processing is completed; multiple data The number of data is greater than or equal to the first threshold, and the first threshold is greater than or equal to 2; the bit size of the plurality of data is greater than or equal to the second threshold, and the second threshold is greater than or equal to 2.

The network device in FIG. 1 is a base station as an example, and the terminal device is a mobile phone as an example.

The following is an example description of the 5G system architecture. As shown in Figure 2, the 5G system architecture consists of a 5G core network (5th generation core, ^5GC ) and a 5G radio access network (5th-Generation wireless access network, NG-RAN). Network communication is possible between networks. Among them, the nodes in the NG-RAN include gNB and ng-eNB. The gNB is the terminal point that provides the user plane and control plane protocol of the New Radio (NR) system, and the ng-eNB provides the user plane and control plane of the E-UTRAN. The endpoint of the protocol stack. In addition, gNB and gNB, gNB and ng-eNB, and ng-eNB and ng-eNB are connected through Xn interface, and gNB, ng-eNB and 5GC are connected through NG interface. The access and mobility management function (AMF) module is connected through the NG-C interface, and the gNB, ng-eNB and the user plane function (UPF) module are connected through the NG-U interface.

In this embodiment of the present application, the network device may be a device with a wireless transceiver function or a chip that can be provided in the device, and the network device includes but is not limited to: an evolved node B (evolved node B, eNB), a radio network controller ( radio network controller, RNC), node B (Node B, NB), network equipment controller (base station controller, BSC), network equipment transceiver station (base transceiver station, BTS), home network equipment (for example, home evolved Node B , or home Node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, wireless fidelity (wireless fidelity, WIFI) system Transmission point (transmission and reception point, TRP or transmission point, TP), etc., can also be equipment used in 4G, 5G or even 6G systems, such as gNB in NR system, or transmission point (TRP or TP), 4G One or a group (including multiple antenna panels) antenna panels of the network equipment in the system, or, it can also be a network node that constitutes a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (distributed unit, DU), or a picocell (Picocell), or a femtocell (Femtocell), or a roadside unit (RSU) in an intelligent driving scenario.

AAU implements some physical layer processing functions, radio frequency processing and related functions of active antennas.

Correspondingly, when the sending end is a terminal device, the receiving end is a network device; when the sending end is a network device, the receiving end is a terminal device.

In order to facilitate the understanding of the embodiments disclosed in the present application, the following two points are described.

(1) The scenarios in the embodiments disclosed in this application are described by taking the scenario of an NR network in a wireless communication network as an example. It should be noted that the solutions in the embodiments disclosed in this application can also be applied to other wireless communication networks. can also be replaced with the names of corresponding functions in other wireless communication networks.

(2) The embodiments disclosed in the present application will present various aspects, embodiments or features of the present application around a system including a plurality of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc., and/or may not include all of the devices, components, modules, etc. discussed in connection with the figures. In addition, combinations of these schemes can also be used.

The technical problem to be solved by the present application is briefly described below.

As shown in Figure 3, in the 5G system, the protocol stack includes: SDAP layer, PDCP layer, RLC layer, MAC layer, and PHY layer. The sender processes each data separately in the order of SDAP->PDCP->RLC->MAC->PHY. For example, as shown in FIG. 4 , the transmitting end performs protocol layer processing on data n, data n+1, and data m at the SDAP layer, the PDCP layer, and the RLC layer, respectively. Wherein, data n and data n+1 belong to data radio bearer (DRB)-x, and data m belongs to DRB-y. DRB refers to the radio bearer of user data, which is used to transmit user data. At the SDAP layer, data of different QoS flows are mapped to corresponding bearers. At the PDCP layer, one bearer corresponds to one PDCP entity, and after the data of one bearer is processed by the PDCP entity, it will be transmitted to the RLC entity and the MAC entity in turn, and the RLC entity and the MAC entity will process it.

In addition, at the RLC layer, the transmitting end processes the data m into segments according to the size capability of the MAC layer to transmit data, to obtain the data a1 and the data a2. When data n, data n+1, and data m are transmitted to the MAC layer, when the sender receives the transmission resources authorized by the network device, according to the size of the transmission resources, data n, data n+1 and data a1 are processed. The end-to-end concatenated processing obtains the concatenated processed data b, so that the data b is sent to the receiving end through the PHY layer.

It can be seen that the sender only processes multiple data cascades into one data at the MAC layer according to the size of the transmission resources, while at other protocol layers, the sender processes each data separately at the above protocol layers. This processing method will As a result, the data processing complexity of the sender is high, resulting in high central processing unit (CPU) overhead.

This embodiment of the present application provides a data processing method 100 . In this method, when the first condition is satisfied, the sending end performs the first cascade processing on the plurality of data, obtains the first data, and sends the first data. Wherein, multiple pieces of data belong to one DRB of the sender, and the first condition includes one or more of the following: a timer expires, the timer is used to control the above-mentioned first cascading processing, and the timer is a time before the above-mentioned first cascading processing. Started after the cascade processing is completed; the number of multiple data is greater than or equal to the first threshold, and the first threshold is greater than or equal to 2; the bit size of multiple data is greater than or equal to the second threshold, and the second threshold is greater than or equal to 2. It can be seen that when the sending end satisfies the above first condition, it performs the first cascade processing on multiple data in the same DRB to obtain the first data, which is conducive to the transmission of the first data to other protocol layers. The sending end can directly The first data is processed instead of processing each of the multiple pieces of data separately, thereby reducing the complexity of data processing at the sending end.

In addition, when the transmitting end is a terminal device and the receiving end is a network device, the network device can reasonably configure the configuration information corresponding to the first condition for the terminal device, so that the terminal device determines the first condition according to the configuration information, and when the first condition is satisfied At the time, the first cascade processing is performed on multiple data in the same DRB, which is beneficial to reduce the complexity of data processing by the terminal device. Specifically, this embodiment of the present application will be described by taking the data processing method 200 as an example.

The embodiments of the present application and related implementations thereof will be described below with reference to the accompanying drawings.

Please refer to FIG. 5 , which is a schematic flowchart of a data processing method 100 provided by an embodiment of the present application. The data processing method 100 is described from the perspective of interaction between the sender and the receiver. The data processing method 100 includes but is not limited to the following steps:

S101. When the sending end satisfies the first condition, the first concatenation process is performed on the plurality of data to obtain the first data; the plurality of data belong to one data radio bearer DRB of the sending end;

The first condition includes one or more of the following: the timer times out, and the timer is used to control the first cascade processing; the timer is started after the previous cascade processing of the first cascade processing is completed; The number is greater than or equal to the first threshold; the first threshold is greater than or equal to 2; the bit size of the plurality of data is greater than or equal to the second threshold; the second threshold is greater than or equal to 2;

S102, the sending end sends the first data;

S103, the receiving end receives the first data from the transmitting end, the first data includes a header and a load part, and the load part includes a plurality of data;

The header includes the number of the multiple data and the same serial number used to identify the multiple data, and the serial number is the serial number of the protocol layer added by the sender after processing the data at a certain protocol layer . For example, if the transmitting end performs the first concatenation processing on multiple pieces of data at the PDCP layer, the same sequence number that identifies the multiple pieces of data is the PDCP SN.

S104. The receiving end obtains a plurality of data according to the header of the first data.

In S101, the timer is started after the previous cascading processing of the first cascading processing is completed, which can be understood as: the sender starts the timer after performing the previous first cascading processing, and then the timer expires After that, the sending end starts the first concatenation process again, that is, the first concatenation process is performed on multiple data of one DRB.

Optionally, the above timer may be started by the sender when any data arrives, that is, the start time of the timer is determined by the sender itself. For example, the sender starts the above-mentioned timer for controlling the first cascade processing when the fourth data arrives. The data arrival in the embodiment of the present application refers to the data arriving at the application layer at the access stratum (AS) layer of the sending end, and the access layer includes any one of the above protocol layers, that is, the data arrival refers to the data arriving at the above any protocol layer.

In an implementation manner, multiple pieces of data belong to the same quality of service (quality of service, QoS) flow of the above DRB. This method is beneficial for the sending end to perform the same first cascade processing on multiple data belonging to the same QoS flow.

In this embodiment of the present application, when the first condition is satisfied, the transmitting end may perform the first concatenation processing on multiple data of the same DRB in any of the foregoing protocol layers. For example, when the first condition is satisfied, the transmitting end performs the first concatenation process on multiple data of the same DRB in the SDAP layer, or performs the first concatenation process on the multiple data of the same DRB in the PDCP layer, etc. . This embodiment of the present application does not limit the protocol layer at which the transmitting end performs the first concatenation processing.

Various implementations of the first condition corresponding to the first cascade processing are described below:

In an implementation manner, the first condition for the sending end to perform the first cascading processing is: the sending end starts a timer for controlling the first cascading processing after the previous completion of the first cascading processing, and After the timer expires, multiple data belonging to the same DRB are processed in the first cascade. For example, after the sender performs the first concatenation process on DRB-1 including data a and data b at the SDAP layer, it starts a timer a for controlling the first concatenation process, and after the timer a times out, the sender The DRB-2 of the SDAP layer also includes data b, data c, and data d, and the first cascade processing is performed on the data b, data c, and data d belonging to the DRB-2 at the SDAP layer.

In another implementation manner, the first condition for the transmitting end to perform the first cascade processing is: when the number of the multiple data is greater than or equal to the first threshold, the transmitting end performs the first condition on the multiple data belonging to the same DRB. The cascading processing may be performing the first cascading processing on the first threshold pieces of data in the same DRB, or performing the first cascading processing on the data included in the same DRB that are smaller than the first threshold. That is to say, the first threshold is the maximum value of the number of data that the transmitting end performs the first concatenation processing, and the number of data that the transmitting end performs the first concatenating data must be less than or equal to the first threshold. For example, if the first threshold is 3, the data in DRB-1 received by the terminal device at the SDAP layer includes data a, data b, data c, and data d. If the number of data included in DRB-1 is greater than the first threshold, then send If the terminal determines that the first condition is satisfied, the first cascade processing can be performed on any two data among data a, data b, data c, and data d, or any three data. For example, the sender performs the first cascade processing on the data b and the data c.

In another implementation manner, the first condition for the transmitting end to perform the first concatenation processing is: when the bit size of the data is greater than or equal to the second threshold, the transmitting end performs the first concatenation on multiple data belonging to the same DRB. deal with. The bit size of the data refers to the total bit size of multiple pieces of data. The transmitting end may perform the first concatenation processing on the data whose bit size is less than or equal to the second threshold of the multiple data in the same DRB. That is to say, the second threshold is the maximum value of the bit size of the data that the transmitting end performs the first concatenation processing.

For example, the second threshold is 5, the data in the DRB-2 received by the transmitting end at the PDCP layer includes data a, data b, and data c, and the bit sizes of data a, data b, and data c are 2bit, 1bit, and 3bit respectively. , the sending end determines that the bit size of data a, data b, and data c is greater than the second threshold, that is, if the first condition is satisfied, then the sending end can perform the first cascade processing on data a and data b; Perform the first cascade processing with the data c; or, the transmitting end performs the first cascade processing on the data b and the data c.

In another implementation manner, the first condition for the transmitting end to perform the first cascade processing is: the transmitting end starts a timer for controlling the first cascade processing after the previous completion of the first cascade processing, and After the timer expires, and the number of multiple data belonging to the same DRB is greater than or equal to the first threshold, the sender performs the first concatenation processing on the multiple data, which may be less than or equal to the multiple data. or equal to the first threshold amount of data to perform the first cascade processing.

For example, if the first threshold is 2, the sender starts the timer for controlling the first cascading processing after performing the first cascading processing on DRB-1 including data a and data b at the SDAP layer, and after the timer expires , the data included in the SDAP layer DRB-1 also includes data b, data c, and data d. If the sender determines that the number of data included in DRB-1 is greater than the first threshold at this time, the sender can Any two data in the data d are subjected to the first cascade processing. For example, the sender performs the first cascade processing on the data c and the data d.

In another implementation manner, the first condition for the transmitting end to perform the first cascade processing is: the transmitting end starts a timer for controlling the first cascade processing after the previous completion of the first cascade processing, and After the timer expires, and the bit size of multiple data belonging to the same DRB is greater than or equal to the second threshold, the transmitting end performs the first concatenation processing on the multiple data, which may be that the bit size in the multiple data is smaller than or equal to the second threshold. or equal to the second threshold amount of data for the first cascade processing.

For example, if the second threshold is 10, the sender starts the timer for controlling the first cascading processing after the first cascading processing of DRB-1 including data a and data b at the SDAP layer, and after the timer expires , the data included in the SDAP layer DRB-1 also includes data c, data d, and data e. The bit sizes of data c, data d, and data e are: 4 bits, 5 bits, and 6 bits, respectively. The sender determines that the bit sizes of data c, data d, and data e are greater than the second threshold, that is, determines that the first condition is satisfied. Then, the transmitting end may perform the first concatenation processing on the data c and the data d, or the transmitting end may perform the first concatenating processing on the data c and the data e.

In another implementation manner, the first condition for the transmitting end to perform the first cascade processing is: the transmitting end starts a timer for controlling the first cascade processing after the previous completion of the first cascade processing, and After the timer expires, the number of multiple pieces of data belonging to the same DRB is greater than or equal to the first threshold, and the bit size of the multiple pieces of data is greater than or equal to the second threshold, the transmitting end performs the first step on the multiple pieces of data. Cascade processing. The sending end may perform the first concatenation processing on the data whose number is less than or equal to the first threshold and whose bit size is less than or equal to the second threshold.

For example, the first threshold is 3, and the second threshold is 8. After performing the first concatenation processing on DRB-1 including data a and data b at the PDCP layer, the sender starts a timer for controlling the first concatenation processing. After the timer expires, the data included in the PDCP layer DRB-1 also includes data c, data d, and data e. The lengths of data c, data d, and data e are: 4 bits, 5 bits, and 6 bits, respectively, the number of the multiple data is equal to the first threshold, and the total bit size of data c, data d, and data e is greater than the second threshold. Then, the transmitting end may perform the first concatenation processing on the data c, the data d, and the data e, or the transmitting end may perform the first concatenating processing on the data c and the data e.

In an implementation manner, the first data includes a header portion and a payload portion, the header portion includes the total number of multiple pieces of data, and the same sequence number used to identify the multiple pieces of data, and the payload portion includes the multiple pieces of data. The same sequence number used to identify multiple data refers to the sequence number (sequence number, SN) added at this protocol layer. The same sequence number for each data refers to the PDCP CN. In this method, the serial number is the same serial number used to identify multiple data, indicating that the sender is a serial number added to the first data uniformly, rather than adding a serial number to each data separately, which is conducive to reducing the transmission end. The complexity of data processing.

For example, after the transmitting end performs the first concatenation processing on the data a and the data b at the PDCP layer, the format of the obtained first data is shown in FIG. 6 . Wherein, the first data includes a header and a load part, the head includes the number n of multiple data, the same serial number PDCP SN used to identify the multiple data, and the load part includes data a and data b. In addition, the header may further include the type of the first data, which is represented by D/C, indicating whether the first data is data (data) or signaling (signalling).

In another implementation manner, the header further includes first indication information corresponding to each data in the plurality of data, where the first indication information is used to indicate the bit size of the corresponding data. For example, L1 in FIG. 6 is used to indicate the bit size of data a, and L2 is used to indicate the bit size of data b. Optionally, the header further includes an optional length for indicating the bit size of the data a, such as L1 (optional) in FIG. 6 .

In another implementation manner, the header further includes second indication information corresponding to the above-mentioned first indication information, where the second indication information is used to indicate the bit length of the corresponding first indication information. For example, F1 in FIG. 6 is used to indicate the bit length of L1, and F2 is used to indicate the bit length of L2.

In an implementation manner, when the sender is mobile, after the sender sends the data to the receiver, the receiver will forward the data to the target network device of the sender. Also at this time, after receiving the first data from the sending end, the receiving end may also forward the first data to the target network device.

In the embodiment of the present application, the first cascade processing performed by the transmitting end on the multiple data may also be referred to as multiplexing of the multiple data, which is not limited in the embodiment of the present application.

It can be seen that, in the embodiment of the present application, when the terminal device satisfies the first condition, the terminal device performs the first cascade processing on the plurality of data, obtains the first data, and sends the first data. This method is conducive to processing only the first data when the first data is transmitted to other protocol layers, rather than processing each data in multiple data separately, thereby reducing the complexity of data processing by the sender and reducing central processing. device overhead.

For example, when the PDCP layer satisfies the first condition, the CPU of the sending end performs the first concatenation processing on 100 pieces of data. Table 1 shows the number of times that the CPU of the sending end processes the 100 pieces of data at each protocol layer under the current technology and the method of the embodiment of the present application. As shown in Table 1, in this embodiment of the present application, the transmitting end performs the first concatenation processing on 100 pieces of data at the PDCP layer. After obtaining the first data, the transmitting end only needs to perform the first concatenation processing when the transmitting end is at the RLC layer and the MAC layer. The data is processed once. Therefore, compared with the number of times of processing the 100 pieces of data in the current technology, the embodiment of the present application can greatly reduce the complexity of processing the 100 pieces of data.

Please refer to FIG. 7 , which is a schematic flowchart of another data processing method 200 provided by an embodiment of the present application. The data processing method 200 is described from the perspective of the interaction between the sending end and the receiving end, and taking the sending end as a terminal device and the receiving end as a network device as an example. The data processing method 200 includes but is not limited to the following steps:

S201. The terminal device receives configuration information corresponding to the first condition, where the configuration information of the first condition is used to determine one or more of the following in the first condition: the duration of the timer, the first threshold, and the second threshold;

S202. The terminal device determines a first condition according to the configuration information; the first condition includes one or more of the following: the timer times out, and the timer is used to control the first cascade processing; the timer is a stage before the first cascade processing The number of multiple data is greater than or equal to the first threshold; the first threshold is greater than or equal to 2; the bit size of multiple data is greater than or equal to the second threshold; the second threshold is greater than or equal to 2.

S203, when the terminal device satisfies the first condition, performs first cascade processing on the plurality of data to obtain first data, where the first data includes a header and a payload;

S204, the terminal device sends the first data;

S205, the network device receives the first data from the terminal device;

S206, the network device obtains a plurality of data according to the header of the first data.

In an implementation manner, the terminal device receives configuration information corresponding to a first condition from the network device, that is, the network device configures the terminal device with configuration information corresponding to the first condition. After receiving the configuration information, the terminal device may determine the first condition according to the parameters in the configuration information.

In another implementation manner, the terminal device receives configuration information corresponding to multiple first conditions from the network device, that is, the network device configures the terminal device with configuration information corresponding to multiple first conditions. After receiving the multiple configuration information, the terminal device determines the first condition according to one of the multiple configuration information, that is, the terminal device selects one configuration information from the multiple configuration information to determine the first condition. The following is an implementation manner for the two terminal devices to select one configuration information for determining the first condition from multiple configuration information:

In an implementation manner, the network device sends third indication information to the terminal device, where the third indication information is used to indicate one of the configuration information among the plurality of configuration information. Therefore, the terminal device receives the third indication information from the network device, and according to the third indication information, determines the first condition from one of the pieces of configuration information. That is to say, the configuration information for the terminal device to determine the first condition is indicated by the network device through the third indication information.

In another implementation manner, the terminal device determines the first condition from one of the above-mentioned multiple configuration information according to the size of the uplink resource authorized by the network device. This manner is helpful for the terminal device to reasonably select configuration information for determining the first condition from multiple configuration information.

In an implementation manner, the configuration information corresponding to the plurality of first conditions is configured by the network device according to one DRB. That is, the first condition determined by the terminal device according to one of the above-mentioned configuration information is applicable to the plurality of data included in the DRB corresponding to the configuration information. This implementation is beneficial for the terminal device to perform the first cascade processing on multiple data included in the same DRB.

For example, the configuration information corresponding to the first condition includes configuration information A, configuration information B, and configuration information C. Configuration information A, configuration information B, and configuration information C are all configured by the network device according to DRB-1. The configuration information A determines the first condition, and the parameter in the configuration information A is that the first preset value is equal to 3, then the network device determines the first condition a according to the configuration information A as: the number of multiple pieces of data included in DRB-1 is greater than When it is equal to or equal to 3, the first cascade processing is performed on a plurality of data included in DRB-1. That is to say, the first condition a determined by the terminal device according to the configuration information A is only applicable to a plurality of data included in the DRB-1.

For another example, the configuration information D corresponding to the first condition is configured by the network device according to DRB-2, and the parameter in the configuration information D is that the second preset value is equal to 5, then the first condition b determined by the terminal device according to the configuration information B is: : When the bit size of multiple data included in DRB-2 is greater than or equal to 5 bits, perform the first concatenation processing on multiple data included in DRB-2, that is, the first condition b determined by the terminal device is only applicable to DRB-2 including of multiple data.

In another implementation manner, the configuration information corresponding to the plurality of first conditions is configured by the network device according to one QoS flow. That is to say, the first condition determined by the terminal device according to one of the above-mentioned configuration information is applicable to a plurality of data included in the QoS flow corresponding to the configuration information. This implementation is beneficial for the terminal device to perform the first cascade processing on multiple data included in the same QoS flow.

For example, if the configuration information corresponding to the first condition determined by the network device is the configuration information for the terminal device to perform the first cascading processing at the service data adaptation protocol (SDAP) layer, then the network device performs the first cascading processing at the service data adaptation protocol (SDAP) layer. Configure a plurality of configuration information corresponding to the first conditions.

In S203, when the first condition is satisfied, the terminal device performs first concatenation processing on the plurality of data to obtain the first data, including: when the first condition is satisfied, connecting the plurality of data end to end to obtain a load part, and The payload section adds a header to obtain the first data. That is to say, when the terminal device satisfies the first condition, it first connects multiple pieces of data head-to-head, and then adds a header to the data after the head-to-tail connection to obtain the first data, so that the added header is information that includes multiple pieces of data . This implementation manner is also applicable to the case where the sending end is a network device, that is, the network device also performs the first cascade processing on a plurality of data according to this implementation manner.

For example, the first condition for the terminal device to perform the first cascading processing is: when the number of data included in DRB-1 is greater than or equal to 3, perform the first cascading processing on less than or equal to 3 data in DRB-1. The multiple data included in the DRB-1 transmitted by the terminal device from the SDAP layer to the PDCP layer are: data a, data b, and data c. It can be seen that the number of data included in DRB-1 is equal to 3, and the terminal device satisfies the first condition and chooses to perform the first cascade processing on data a, data b, and data c. Therefore, the terminal device connects the data a, the data b, and the data c end to end to obtain the payload part a as shown in FIG. 8 , and then adds the header a to the payload part a to obtain the first data a. It can be seen from FIG. 8 that the load part a is obtained by connecting data a, data b, and data c end to end. The format of the header a is as described in the data processing method 100, and details are not repeated here.

For another example, as shown in FIG. 9 , the terminal device includes 4 pieces of data from DRB-2 of the PDCP layer, and each data includes an Internet Protocol Header (IP Header) and an Internet Protocol Payload (IP Payload). The first condition for the terminal device to perform the first concatenation processing is: when the number of data included in the DRB-2 is greater than 2, the first concatenation processing is performed on the two data in the DRB-2. Therefore, the terminal device connects each two of the four data end-to-end to obtain the payload part a and the payload part b. In addition, the terminal device determines that the payload part a and the payload part b satisfy the first condition, and the bit sizes of the payload part a and the payload part b are within the capability range of the transmitting end to perform the first concatenation processing, then the terminal device will use the payload part a Connect with the load part b end to end to obtain the load part c, and then add the PDCP header to the load part c to obtain the first data m. Wherein, the load part c includes a packet data convergence layer protocol sequence service data unit-1 (PDCP service data unit, PDCP SDU 1) and PDCP SDU 2. The first data m includes a PDCP header (PDCP header) and a PDCP SDU. The header c is a header added for the four pieces of data, and contains information of each data. The specific format is shown in Figure 9, and details are not repeated here.

In an implementation manner, after obtaining the payload, the terminal device may process the payload at the protocol layer to obtain the processed payload, and then add a header to the processed payload to obtain the first data. For example, at the PDCP layer, the processing of the payload part by the terminal device includes: encryption, integrity protection, and the like. For another example, in the AM mode of the RLC layer, the processing of the payload part includes: automatic retransmission request, segmentation, reassembly, and the like. This implementation is also applicable to the case where the sender is a network device, that is, the network device can also process the payload part at the protocol layer to obtain the processed payload part, and then add a header to the processed payload part to obtain the first data .

In an implementation manner, before receiving the configuration information corresponding to the first condition from the network device, the terminal device may also report the cascading processing capability for performing the first cascading processing to the network device, so that the network device can perform the first cascade processing according to the first level. The cascade processing capability of cascade processing configures reasonable configuration information for the terminal device, so that the terminal device receives the configuration information corresponding to the first condition determined by the network device according to the cascade processing energy level. This implementation is beneficial for the terminal device to obtain configuration information adapted to the terminal device, thereby ensuring that the first cascade processing is performed within the cascade processing capability of the terminal device.

Wherein, the cascading processing capability of the first cascading processing includes one or more of the following: the minimum number of data that the terminal device performs the first cascading processing; the maximum number of data that the terminal device performs the first cascading processing. value; the minimum value of the data bit size for the terminal device to perform the first concatenation process; the maximum value of the data bit size for the terminal device to perform the first concatenation process.

The following describes several implementations for the network device to determine the configuration information according to the cascading processing capability for reporting the cascading processing capability corresponding to different first conditions:

In an implementation manner, the cascading processing capability of the first cascading processing reported by the terminal device is the minimum value of the number of data to perform the first cascading processing, then the first threshold in the configuration information determined by the network device should be greater than or equal to the minimum value. This implementation manner can make full use of the ability of the terminal device to perform the first cascade processing, so that the terminal device can perform the first cascade processing on multiple data of the same DRB as much as possible. For example, if the minimum value of the number of data to perform the first concatenation processing reported by the terminal device is 3, then the first threshold in the configuration information determined by the network device should be greater than or equal to 3, and the terminal device can be in the same DRB. When the number of data is greater than or equal to 3, the first cascade processing is performed on the data less than or equal to 3 in the DRB.

In another implementation manner, the cascading processing capability of the first cascading processing reported by the terminal device is the maximum value of the number of data to perform the first cascading processing, and the first threshold in the configuration information determined by the network device should be less than or equal to the maximum value, at this time, it can be ensured that the terminal device performs the first cascade processing on multiple data within the maximum data processed by the first cascade. For example, if the maximum number of data for performing the first concatenation process reported by the terminal device is 5, the first threshold in the configuration information determined by the network device should be less than or equal to 5.

In another implementation manner, the cascading processing capability of the first cascading processing reported by the terminal device is the minimum and maximum values of the number of data to perform the first cascading processing, then the first cascading processing capability in the configuration information determined by the network device The threshold should be greater than or equal to the minimum value and less than or equal to the maximum value. This implementation can ensure that the terminal device can not only fully utilize the first cascade processing capability of the terminal device, but also ensure that the first cascade processing is performed on multiple data within the range of the terminal device's cascade processing capability. For example, the minimum value of the number of data to perform the first cascading processing reported by the terminal device is 3, and the maximum value of the number of data to perform the first cascading processing is 8, then the No. A threshold value should be greater than or equal to 3 and less than or equal to 8, for example, the first threshold value is 6.

In another implementation manner, the first cascading processing capability reported by the terminal device is the minimum value of the data bit size for performing the first cascading processing, and the second threshold in the configuration information determined by the network device should be greater than or equal to the minimum value. value. This implementation is beneficial for the terminal device to perform the first cascade processing on data with as many bits as possible.

In another implementation manner, the first cascading processing capability reported by the terminal device is the maximum value of the data bit size for performing the first cascading processing, and the second threshold in the configuration information determined by the network device should be less than or equal to the maximum value. value. This implementation manner is also beneficial for the terminal device to perform the first cascade processing on a plurality of data within the capability range of being able to perform the first cascade processing.

In another implementation manner, the first cascading processing capability reported by the terminal device is the minimum and maximum value of the data bit size for performing the first cascading processing, then the second threshold in the configuration information determined by the network device should be greater than or equal to the minimum value and less than or equal to the maximum value. This implementation is also beneficial for the terminal device to not only perform the first cascade processing on multiple data within the capability range of the first cascade processing, but also make full use of the capability of performing the first cascade processing as much as possible. For example, the first cascading processing capability reported by the terminal device is that the minimum value of the bit size of the data to perform the first cascading processing is 7, and the maximum value is 20, then the second threshold in the configuration information determined by the network device should be greater than or equal to 7, less than or equal to 20, for example, the second threshold is 15.

In the above implementation manner, the number of data and the data bit size reported by the terminal device to perform the first cascade processing can be combined with any two, and the network device also determines the number of data in the configuration information correspondingly according to the cascade processing capability reported by the terminal device. a threshold and a second threshold. For example, the first cascading processing capability reported by the terminal device is the minimum value of the number of data to perform the first cascading processing and the maximum value of the data bit size to perform the first cascading processing, then the first condition determined by the network device In the corresponding configuration information, the first threshold value should be greater than or equal to the minimum value of the data number, and the second threshold value should be less than or equal to the maximum value of the data bit size.

In another implementation manner, before receiving the configuration information corresponding to the first condition from the network device, the terminal device may also send fourth indication information to the network device, where the fourth indication information is used to indicate the first cascade connection determined by the sender The number of data processed and/or the bit size of data processed in the first cascade. Therefore, after receiving the fourth indication information, the network device determines the configuration information corresponding to the first condition according to the number of data in the first concatenation process and/or the bit size of the first concatenation process determined by the transmitting end. For example, if the fourth indication information indicates that the number of data to be processed in the first cascade determined by the terminal device is 10, the network device determines that the first threshold in the configuration information corresponding to the first condition is 10. For another example, the fourth indication information indicates that the data bit size of the first concatenated processing determined by the terminal device is 20, and the network device determines that the second threshold in the configuration information corresponding to the first condition is 20.

As mentioned above, the header of the first data includes information of each data, such as the number of multiple data, and the length information of multiple data. Therefore, in S206, the receiving end may obtain a plurality of data according to the information of the plurality of data in the header of the first data.

It can be seen that, in this embodiment of the present application, the terminal device determines the first condition according to the configuration information corresponding to the first condition from the network device, and then, when the first condition is satisfied, performs the first cascade processing on multiple data in the same DRB, Obtain the first data and send the first data. This method is beneficial for the terminal device to perform the first cascade processing on multiple data in the same DRB according to the first condition within the capability range of the first cascade processing, so that when the first data is transmitted to other protocol layers, The terminal device only needs to process the first data, instead of processing each data in the plurality of data, which can reduce the complexity of data processing by the terminal device.

For the above data processing method 100 and data processing method 200, the following implementations may also be included:

In an implementation manner, sending the above-mentioned first data by the sending end includes: when the sending end obtains transmission resources, performing second concatenation processing on the first data and the second data, and sending the data after the second concatenation processing, The second data is obtained by the sender based on the first cascaded processing and is different from the first data. That is to say, after the sender obtains the first data and the second data by performing the first concatenation processing, the sender can also perform the second cascading processing on the first data and the second data, and the sender must, when obtaining the transmission resources, Only then can the second cascade processing be performed on the first data and the second data. That is to say, when the sender is a terminal device, when the terminal device obtains the uplink resources authorized by the network device, it can perform second concatenation processing on the first data and the second data; when the sender is a network device, the network device determines the downlink resource. When transmitting resources, a second concatenation process may be performed on the first data and the second data. The second data and the first data may be data of the same DRB or the same QoS flow, or may be data of different DRBs or different QoS flows.

In an implementation manner, when the sending end obtains the transmission resources, the second concatenation processing is performed on the first data and the second data, including: when the sending end obtains the transmission resources, adding a header to the first data and the second data respectively. Parts are connected end-to-end to obtain the data after the second cascade processing. It can be seen that the sender performs the second cascading process by first adding a header to each data, and then connecting each data after the header is added end to end, while the first cascading process is to first connect each data end to end, and then connect the end to end. A header is added to the data, so that the first cascade processing method can reduce the processing complexity of the sender.

For example, as shown in FIG. 10 , when the terminal device obtains the uplink resource authorized by the network device, there are the first data a and the second data a after the first concatenation processing. The terminal device chooses to perform the second concatenation process on the first data a and the second data b, that is, first add the header a to the first data a, add the header b to the second data b, and add the first data after the header. The data a and the second data b are connected end-to-end to obtain the second cascade-processed data n.

In an implementation manner, after obtaining the first data, the sending end may also start the timer for performing the first cascade processing again, and discard the first data after the timer expires.

In an implementation manner, the sender performs the first cascade processing on multiple data, and stores the first data locally after obtaining the first data. If the above timer times out after being restarted, it indicates that the sender has stored the first data. The packet is sent out, so the sender can discard the first data packet that exists locally.

In another implementation manner, if the above-mentioned timer times out after being restarted, it indicates that the sender has not sent the first data, but the duration of the timer has exceeded, and the locally stored first data also needs to be discarded.

In another implementation manner, after receiving multiple pieces of data, the sender also stores multiple pieces of data locally. At this time, the above-mentioned timer may also be used to control the discarding of the plurality of data. That is to say, after obtaining the first data, the sender restarts the above-mentioned timer again, and after the timer expires, discards the multiple pieces of data.
