To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application is first described in detail with reference to FIG. 1 .

FIG. 1 is a schematic diagram of a wireless communication system 100 suitable for an embodiment of the present application. As shown in FIG. 1 , the wireless communication system 100 may include at least one network device, such as the network device 111 shown in FIG. 1 , and the wireless communication system 100 may also include at least one terminal device, such as the terminal device 121 shown in FIG. 1 . to the terminal device 123. Both network equipment and terminal equipment can be configured with multiple antennas, and network equipment and terminal equipment can communicate using multi-antenna technology.

As shown in FIG. 2 , the wireless communication system 100 may include at least one terminal device, such as the terminal device 211 shown in FIG. 2 , and the wireless communication system 100 may also include at least one network device, such as the network device 221 shown in FIG. 2 . to network device 223. Both the network device and the terminal device can be configured with multiple antennas, and the network device and the terminal device can communicate using the multi-antenna technology.

It should be understood that the above-mentioned FIG. 1 and FIG. 2 are only exemplary descriptions, and the present application is not limited thereto.

It should also be understood that the network device in the wireless communication system may be any device having a wireless transceiver function. The interface between the network device and the terminal device may be a Uu interface (or called an air interface). Of course, in future communications, the names of these interfaces may remain unchanged, or may be replaced with other names, which are not limited in this application.

A network device is an access device that a terminal device wirelessly accesses into a mobile communication system, which can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), or a 5G mobile communication system. The next generation NodeB (gNB), the base station in the future mobile communication system or the access node in the WiFi system, etc. The network device may include a centralized unit (Centralized unit, CU), or a distributed unit (Distributed unit, DU), or include a CU and a DU.

In this embodiment of the present application, the functions of the network device may also be implemented through multiple network function entities, and each network function entity is used to implement part of the functions of the network device. These network function entities can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (eg, a cloud platform).

(1) Protocol layer structure

The communication between the network device and the terminal device follows a certain protocol layer structure. For example, the control plane protocol layer structure may include a radio resource control (RRC) layer, a packet data convergence protocol (packet data convergence protocol, PDCP) layer. , radio link control (radio link control, RLC) layer, media access control (media access control, MAC) layer and physical layer; user plane protocol layer structure may include PDCP layer, RLC layer, MAC layer and physical layer, in In a possible implementation, the PDCP layer may further include a service data adaptation protocol (SDAP) layer.

Taking the data transmission between the access network device and the terminal device as an example, the data transmission needs to go through the user plane protocol layer, such as the SDAP layer, PDCP layer, RLC layer, MAC layer, and physical layer, among which SDAP layer, PDCP layer, The RLC layer, the MAC layer, and the physical layer may also be collectively referred to as the access layer. Exemplarily, data is transmitted between the access network device and the terminal device by establishing at least one data radio bearer (DRB), and each DRB may correspond to a set of functional entities, such as including a PDCP layer entity, the At least one RLC layer entity corresponding to the PDCP layer entity, at least one MAC layer entity corresponding to the at least one RLC layer entity, and at least one physical layer entity corresponding to the at least one MAC layer entity. It should be noted that signaling can also be transmitted between the access network device and the terminal device by establishing at least one signaling radio bearer (SRB). DRB and SRB can be collectively referred to as radio bearer (RB) .

Take the next line data transmission as an example, the downward arrow in FIG. 3a indicates data transmission, and the upward arrow indicates data reception. After the SDAP layer entity obtains the data from the upper layer, it can map the data to the PDCP layer entity of the corresponding DRB according to the QoS flow indicator (QFI) of the data, and the PDCP layer entity can transmit the data to at least one corresponding to the PDCP layer entity. One RLC layer entity is further transmitted by at least one RLC layer entity to the corresponding MAC layer entity, and then the MAC layer entity generates a transport block, and then performs wireless transmission through the corresponding physical layer entity. The data is encapsulated correspondingly in each layer. The data received by a certain layer from the upper layer of the layer is regarded as the service data unit (SDU) of the layer, and becomes the protocol data unit (Protocol data) after layer encapsulation. unit, PDU), and then passed to the next layer. For example, the data received by the PDCP layer entity from the upper layer is called PDCP SDU, the data sent by the PDCP layer entity to the lower layer is called PDCP PDU; the data received by the RLC layer entity from the upper layer is called RLC SDU, and the data sent by the RLC layer entity to the lower layer Called RLC PDU. Among them, data can be transmitted between different layers through corresponding channels. For example, the RLC layer entity and the MAC layer entity can transmit data through a logical channel (LCH), and between the MAC layer entity and the physical layer entity can be transmitted through the Transport channel (Transport channel) to transmit data.

Exemplarily, according to Fig. 3a, it can also be seen that the terminal device also has an application layer and a non-access layer; wherein, the application layer can be used to provide services to applications installed in the terminal device, for example, the terminal device receives Downlink data can be sequentially transmitted from the physical layer to the application layer, and then provided by the application layer to the application program; for another example, the application layer can obtain the data generated by the application program, transmit the data to the physical layer in turn, and send it to other communication devices. The non-access layer can be used for forwarding user data, for example, forwarding the uplink data received from the application layer to the SDAP layer or forwarding the downlink data received from the SDAP layer to the application layer.

(2) CU and DU

In this embodiment of the present application, the network device may include one or more centralized units (Centralized units, CUs) and one or more distributed units (Distributed units, DUs), and multiple DUs may be centrally controlled by one CU. As an example, the interface between the CU and the DU may be referred to as an F1 interface, wherein the control plane (Control panel, CP) interface may be F1-C, and the user plane (User panel, UP) interface may be F1-U. The CU and DU can be divided according to the protocol layers of the wireless network: for example, as shown in Figure 3b, the functions of the PDCP layer and the above protocol layers are set in the CU, and the functions of the protocol layers below the PDCP layer are set in the DU. For example, the DU may include the RLC layer, MAC layer and physical (Physical, PHY) layer.

In one possible design, the DU may include functions of the RLC layer, functions of the MAC layer, and part of the functions of the PHY layer. Illustratively, a DU may include functions of higher layers in the PHY layer. The functions of the upper layers in the PHY layer may include cyclic redundancy check (Cyclic redundancy check, CRC) functions, channel coding, rate matching, scrambling, modulation, and layer mapping; or, the functions of the upper layers in the PHY layer may include cyclic redundancy check (CRC) functions. Redundancy checking, channel coding, rate matching, scrambling, modulation, layer mapping and precoding. The functions of the lower layers in the PHY layer may be implemented by another network entity independent of the DU, wherein the functions of the lower layers in the PHY layer may include precoding, resource mapping, physical antenna mapping, and radio frequency functions; or, the functions of the lower layers in the PHY layer may Includes resource mapping, physical antenna mapping, and radio frequency functions. This embodiment of the present application does not limit the function division of the upper layer and the lower layer in the PHY layer. When the functions of the lower layers in the PHY layer can be implemented by another network entity independent of the DU, the DU sends data or information to other communication devices (such as terminal equipment, core network equipment), which can be understood as: the DU executes the RLC layer and the MAC layer. function, and, part of the function of the PHY layer. For example, after the DU completes the functions of the RLC layer and the MAC layer, as well as, cyclic redundancy check, channel coding, rate matching, scrambling, modulation, and layer mapping, the network that performs the functions of the lower layers in the PHY layer is independent from the DU. The entity performs the remaining functions of mapping and sending on physical resources.

It can be understood that the above-mentioned division of the processing functions of CU and DU according to the protocol layer is only an example, and can also be divided in other ways, for example, the functions of the protocol layer above the RLC layer are set in the CU, and the functions of the RLC layer and the following protocol layers are set. The function is set in the DU. For example, the CU or DU can be divided into functions with more protocol layers, and for example, the CU or DU can also be divided into partial processing functions with protocol layers. In one design, some functions of the RLC layer and functions of the protocol layers above the RLC layer are placed in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are placed in the DU. In another design, the functions of the CU or DU can also be divided according to the service type or other system requirements, for example, by the delay, the functions whose processing time needs to meet the delay requirements are set in the DU, and do not need to meet the delay. The required functionality is set in the CU. In another design, the CU may also have one or more functions of the core network. Exemplarily, the CU can be set on the network side to facilitate centralized management; the DU can have multiple radio functions, or the radio functions can be set remotely. This embodiment of the present application does not limit this.

Exemplarily, the functions of the CU may be implemented by one entity, or may also be implemented by different entities. For example, as shown in Figure 3c, the functions of the CU can be further divided, that is, the control plane and the user plane can be separated and implemented by different entities, namely the control plane CU entity (ie the CU-CP entity) and the user plane CU entity. (ie the CU-UP entity), the CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the functions of the network device. The interface between the CU-CP entity and the CU-UP entity may be the E1 interface, the interface between the CU-CP entity and the DU may be the F1-C interface, and the interface between the CU-UP entity and the DU may be the F1-U interface interface. Among them, one DU and one CU-UP can be connected to one CU-CP. Under the control of the same CU-CP, one DU can be connected to multiple CU-UPs, and one CU-UP can be connected to multiple DUs.

Based on FIG. 3c, FIG. 3d is a schematic diagram of the distribution of an air interface protocol stack. As shown in Figure 3d, for both the user plane and the control plane, the air interface protocol stack may be RLC, MAC, and PHY in the DU, and PDCP and above protocol layers in the CU.

It should be noted that: in the architectures shown in the foregoing Figures 3b to 3d, the signaling generated by the CU may be sent to the terminal device through the DU, or the signaling generated by the terminal device may be sent to the CU through the DU. The DU may not parse the signaling, but directly encapsulate it through the protocol layer and transparently transmit it to the terminal device or CU. In the following embodiments, if the transmission of such signaling between the DU and the terminal device is involved, at this time, the sending or receiving of the signaling by the DU includes this scenario. For example, the signaling of the RRC or PDCP layer will eventually be processed as the data of the physical layer and sent to the terminal device, or converted from the received data of the physical layer. Under this architecture, the signaling of the RRC or PDCP layer can also be considered to be sent by the DU, or sent by the DU and the radio frequency device.

The terminal device involved in the embodiments of the present application includes a device that provides voice and/or data connectivity to a user, for example, may include a handheld device with a wireless connection function, or a processing device connected to a wireless modem. The terminal equipment may communicate with the core network via a radio access network (RAN), and exchange voice and/or data with the RAN. The terminal equipment may include user equipment (UE), wireless terminal equipment, mobile terminal equipment, device-to-device (D2D) terminal equipment, vehicle to everything (V2X) terminal equipment , Machine-to-machine/machine-type communications (M2M/MTC) terminal equipment, Internet of things (IoT) terminal equipment, subscriber units, subscriber stations, mobile stations, remote stations , access point (AP), remote terminal, access terminal, user terminal, user agent, or user equipment, etc. For example, these may include mobile telephones (or "cellular" telephones), computers with mobile terminal equipment, portable, pocket-sized, hand-held, computer-embedded mobile devices, and the like. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (personal digital assistants), PDA), etc. Also includes constrained devices, such as devices with lower power consumption, or devices with limited storage capacity, or devices with limited computing power, etc. For example, it includes information sensing devices such as barcodes, radio frequency identification (RFID), sensors, global positioning system (GPS), and laser scanners.

At present, an implementation method of data transmission using network coding is that the sender encodes a group of data packets uniformly, divides them into N equal-sized data blocks, performs network coding uniformly, and outputs M (M>N after encoding). ) in small data blocks for transmission. This set of data can be recovered as long as the receiver correctly receives any N small data blocks and decodes them.

FIG. 4 is a flowchart of a method 400 for data transmission using network coding applicable to the embodiment of the present application. As shown, the method 400 may include the following steps:

S401, the base station sends an RRC message to the terminal device.

Exemplarily, the base station may send an RRC message to the terminal device to configure the number of blocks to be encoded in one encoding group to be 120.

S402, the PDCP layer of the base station generates a group of PDCP PDUs from the data packets.

Illustratively, the PDCP layer of the base station may receive data packets, ie, PDCP SDUs, and then generate a set of PDCP PDUs from the received data packets. Specifically, the PDCP layer of the base station can generate a PDCP PDU through network coding steps such as header compression, encryption, and adding PDCP header integrity protection. The integrity protection is then executed, which is not limited in this application.

S403, the PDCP layer of the base station performs network coding processing on the PDCP PDU.

Exemplarily, FIG. 5 is a flowchart of network coding applicable to this embodiment of the present application. As shown in FIG. 5 , the network coding may include three steps:

(1) Divide 60 PDCP PDU packets into a group, and divide these data packets into 120 data blocks of equal size, which are called a group of blocks to be encoded;

(2) Perform network coding on 120 data blocks, and output 132 coded blocks after coding, of which 12 are redundant blocks, and each redundant block is composed of some bits in the 120 data blocks. FIG. 6 is a schematic diagram of network coding applicable to this embodiment of the present application. As shown in FIG. 6 , a vector matrix with 120 columns and 132 rows is a coding coefficient codebook, and the coding coefficient vector in each row of a matrix corresponds to an index index. Among them, x1, x2,...,x120 corresponds to a set of blocks to be coded, y1, y2,...,y120 corresponds to 120 coding blocks, y121, y122,..., y132 are redundant blocks; each coding block generates a coding header corresponding to , each encoding header includes:

(a) coding coefficient vector indication information, used to indicate the index corresponding to the coding coefficient vector in the coding coefficient codebook;

(b) group number, used to indicate the number of the group to which the coding block belongs;

(c) An optional number, used to indicate the number of the coding block within a coding group.

(3) Generate a CRC code for each coding block with a coding header, add it to the coding block, and generate the final coding block.

S404, the RLC layer of the base station generates an RLC PDU and submits it to the MAC layer.

For example, the RLC layer of the base station may receive the encoded block, add an RLC header to the encoded block, generate an RLC PDU, and deliver it to the MAC layer.

S405, the MAC layer of the base station adds a MAC sub-header to the RLC PDU to generate a MAC sub-PDU.

For example, the MAC layer of the base station may add a MAC sub-header to the RLC PDU to generate a MAC sub-PDU. Wherein, if the size of the MAC CE is variable, the MAC subheader includes the L field, indicating the length information of the MAC CE. Among them, the MAC layer selects MAC sub-PDUs in the order of logical channel priority from high to low according to the size of the transmission resources and multiplexes them together to form a MAC PDU, and then submits it to the physical layer to add a CRC to generate a TB, which is sent by the physical layer.

S406, the physical layer of the terminal device submits the TB that has passed the CRC check to the MAC layer.

For example, the terminal device may receive the TB on the PDSCH according to the downlink control information on the PDCCH, and submit the TB that has passed the CRC check to the MAC layer through the physical layer.

S407, the MAC layer of the terminal device submits the MAC SDU to the RLC layer, and the RLC submits the RLC SDU to the PDCP layer.

For example, the MAC layer of the terminal device can parse the MAC sub-PDU, and submit the MAC SDU to the RLC layer according to the logical channel identifier in the sub-header of the MAC sub-PDU, and the RLC submits the RLC SDU to the PDCP layer.

S408, the PDCP layer of the terminal device performs network decoding.

For example, the PDCP layer of the terminal device may perform network decoding after receiving the RLC SDU. Among them, a possible implementation of the network decoding steps is as follows:

(1) extract each coding block according to the size of the coding block;

(2) parse the code header from the code block passed by the CRC check to obtain the group number of the code block and the number of the code block;

(3) Decode the 120 code blocks that have passed the CRC check of the code blocks belonging to the same group number together to recover 60 PDCP PDUs.

Based on the above solution, when some bits in the TB receive errors and cause the CRC check to fail, there is a situation: the bits in the above 120 coded blocks are incorrect, and the redundant blocks are correctly received. Since the wrong bit is received, it can be recovered by the correct bit in the redundant block. However, the physical layer of the receiving end only submits the TB that has passed the CRC check to the MAC layer, so that the receiving end cannot obtain the gain of the redundant coding block.

Based on this, an embodiment of the present application provides a data processing method, which is used to improve the reliability of data transmission and reduce the processing delay.

FIG. 7 is a schematic diagram of a data processing method 700 provided by an embodiment of the present application. As shown in Figure 7, the method includes the following steps:

S701, the network device sends configuration information to the terminal device, and correspondingly, the terminal device receives the configuration information from the network device. The configuration information is used for network coding by the terminal device.

Exemplarily, the configuration information includes a first network coding parameter, and the first network coding parameter includes at least one set of network coding parameters. Wherein, each group of network coding parameters may include a first index number, and the first index number may correspond to at least one of the following parameters: N, the bit size of each coding block in the first coding block, and the ratio of N to M. Wherein, N is the number of to-be-coded blocks in a set of to-be-coded blocks, and M is the number of coding blocks in the first coding block obtained after performing network coding on a set of coding blocks. Table 1 is an example of the configuration information including the first network coding parameter.

Table 1

As shown in Table 1, among the first network coding parameters included in the configuration information, there are three groups of network coding parameters. Wherein, the first index number of the first group of network coding parameters is 100, corresponding to the first group of network coding parameters including the parameter: N; the first index number of the second group of network coding parameters is 010, corresponding to the second group of network coding parameters Include parameters: the bit size of each encoding block in the first encoding block; the first index number of the third group of network encoding parameters is 101, and the corresponding third group of network encoding parameters includes parameters: N, the ratio of N and M .

Further, the configuration information may further include information of the first channel, and encode a group of blocks to be encoded corresponding to the first channel. Wherein, the first channel may include at least one radio bearer or at least one logical channel.

In a possible implementation manner, the above configuration information may further include at least one second index number, where the second index number is a logical channel index number, and one logical channel index number corresponds to one logical channel, in other words, a second index number Corresponds to a logical channel. Therefore, the logical channel corresponding to the second index number can be made to perform network coding by using the network coding parameter represented by the first index number.

In another possible implementation manner, the above configuration information may further include at least one third index number, where the third index number is a radio bearer index number, and one radio bearer index number corresponds to one radio bearer, in other words, a third index The number corresponds to a radio bearer. Therefore, the radio bearer corresponding to the configuration information can be made to perform network coding by using the network coding parameter represented by the first index number.

In another possible implementation manner, the configuration information may also be PDCP configuration information. For example, the PDCP configuration information may include at least one fourth index number, where the fourth index number is a radio bearer index number, and one radio bearer index number corresponds to one radio bearer, in other words, one fourth index number corresponds to one radio bearer. Therefore, the radio bearer corresponding to the PDCP configuration information can use the network coding parameter represented by the first index number to perform network coding.

In another possible implementation, the configuration information may also be logical channel configuration information. For example, the logical channel configuration information may include at least one fifth index number, where the fifth index number is a logical channel index number, and one logical channel index number corresponds to one logical channel, in other words, one fifth index number corresponds to one logical channel. Therefore, the logical channel corresponding to the logical channel configuration information can be network-coded using the network coding parameter represented by the first index number.

S702, the terminal device encodes a group of blocks to be encoded.

For example, after receiving the configuration information sent by the network device, the terminal device may determine the first network coding parameter through the configuration information, and then use the first network coding parameter for a set of blocks to be coded in the corresponding logical channel or radio bearer. Encoding is performed to obtain the first encoding block.

Wherein, the second coding block includes at least one coding block in the first coding block.

Specifically, the terminal device may be unable to send all the coding blocks in the first coding block due to insufficient resources. Therefore, the terminal device can send some or all of the coding blocks in the first coding block to the network device, that is, send the second coding block to the network device.

Based on the above solution, the terminal device encodes a set of blocks to be encoded by receiving configuration information including at least one set of network coding parameters. During this process, the network device can adjust the network coding parameters according to factors such as channel conditions and traffic fluctuations. Obtain a balance between resource overhead, network coding reliability, and processing latency.

As shown in Figure 13, in the dual-connection scenario (two network devices), starting from bit 0, the bit value corresponding to the logical channel identifier of the main network device (the wireless access node that provides the control plane connection to the core network) is put first. , and then place the bit value corresponding to the logical channel identifier of the slave network device (the radio access node that does not provide a control plane connection to the core network).

It should also be understood that, in the design of the above-mentioned MAC CE, the logical channel channel identifier configured with the network coding function can be replaced by the radio bearer identifier configured with the network coding function, the second field carries the radio bearer identifier, and the multiple bits of the third field. They are arranged in ascending or descending order of the identifiers of the radio bearers.

It should be understood that the second indication information can also indicate to enable the network coding function of the uplink, or indicate the effective system frame number (System frame number, SFN), and the SFN is an SFN that is closest to the time when the terminal device receives the second indication information ).

It should also be understood that the second indication information may also be carried in the DCI, and the network device configures the terminal device with the second indication information by sending the DCI information to the terminal device. The DCI may be the DCI in the PDCCH that schedules data transmission in real time, or the DCI ordered by the PDCCH. Since the logical channel ID has more bits, it can be considered to use shorter bits to map the logical channel ID. For example, the lower 2 to 3 bits of the 5 bits of the logical channel identifier are used to indicate, or the network device configures a logical channel identifier to correspond to a value of 2 to 3 bits, as shown in Table 2, using two bits to support a maximum of 4 The logical channel supports network coding, and uses 3 bits to support up to 9 logical channels to support network coding.

S1505, the terminal device generates a second data packet.

For example, the terminal device may encode a group of blocks to be encoded to obtain a second encoded block according to the ordering of logical channel priorities, and perform at least one processing on the second encoded block to obtain a second data packet.

In a possible implementation manner, the second data packet includes sixth indication information, and the sixth indication information indicates the position of the sub-data packet including the second coding block in the second data packet.

Specifically, the sixth indication information may determine that the sub-packet including the second encoding block is in the second data packet by indicating the offset of the first sub-packet of the second data packet and the sub-packet including the second encoding block s position.

In a possible implementation manner, the position of the sub-packet including the second encoding block may be determined by the offset between the header position of the first sub-packet and the header position of the sub-packet including the second encoding block , wherein the first sub-packet is a sub-packet used to indicate the position of the sub-packet including the second coding block.

Further, the total length information of the sub-data packets including the second coding block is also included. Preferably, the first sub-packet can be placed first, and the sub-packets including the second coding block can be placed next to each other.

Further, the total length information of the sub-data packets including the second coding block is also included. Preferably, the first sub-packet can be placed at the front, and the sub-packets including the second coding block can be placed next to each other. Thereby, with respect to the offset of the header of the first sub-block and the header of the sub-packet containing the second coding block, the tail of the first sub-block and the header of the sub-packet containing the second coding block The value of the offset of the part is small, which can reduce the overhead.

As shown in Figure 18, consider introducing the first sub-packet, the first sub-packet contains a variable-length MAC CE, the MAC CE includes a MAC subheader, and the L field of the MAC subheader indicates the length of the MAC CE, The F field indicates whether the bit length of the L field is 8 bits or 16 bits; the MAC CE carries the logical channel identifier corresponding to the second coding block, and the sub-data packet including the second coding block is at the start position of the second data packet and includes the second The total length of the subpackets of the encoded block in the second packet. Therefore, when the sizes of network coding blocks with different logical channels are not equal, the MAC layer can extract MAC sub-PDUs (ie, sub-data packets) with reference to the respective coding block sizes. Meanwhile, by referring to the contents of Table 2 above, when there are more logical channel identifier bits, a logical channel identifier with a shorter bit can be used to correspond to one logical channel identifier, thereby reducing the indication overhead.

Optionally, if the MAC CE has indicated a logical channel, and the length of the same MAC SDU is the same, in order to reduce the subheader overhead, the network device may not add the MAC subheader to the MAC subPDU of the coding block.

S1506, the terminal device sends the second data packet to the network device, and correspondingly, the network device receives the second data packet from the terminal device.

If the network device instructs the terminal device to authorize the sending of a certain logical channel, the terminal device sends the second data packet of the logical channel through the authorization.

For example, the terminal device may send the second data packet to the network device, and the network device may determine the position of the sub-data packet including the second coding block in the second data packet according to the sixth indication information.

Based on the above solution, the position of the sub-packet including the second encoding block in the second data packet can be determined by the offset of the first sub-packet and the sub-packet including the second encoding block, so that in the CRC check In the case of failure, the MAC layer can accurately extract the coding block, submit it to the upper layer, and enable the network coding function.

The sub-data packets of the two coding blocks are in one-to-one correspondence, and the check code is used to determine whether the sub-data packets including the second coding block are correctly received.

In a possible implementation manner, the terminal device may generate a CRC according to each sub-data packet in the second data packet (may be regarded as a MAC PDU), and add the CRC to the back of the sub-data packet. FIG. 21 is a schematic diagram of a second data packet for generating a CRC according to an embodiment of the present application. As shown in FIG. 21 , the first sub-data block is used to indicate the position of the MAC sub-PDU including the second coding block in the second data packet, and the second coding block is a network coding block. The terminal device generates a CRC for each MAC sub-PDU containing the second coding block, and adds it to the back of the MAC sub-PDU. Wherein, for the MAC sub-PDU that does not include the second coding block, a CRC is generated, and a CRC is optionally generated and added to the back of each MAC sub-PDU. After the network device receives the second data packet, the MAC layer may submit the MAC SDU of the MAC sub-PDU whose CRC has passed the verification to the RLC layer. Meanwhile, in this scheme, the CRC can also be placed in front of each MAC sub-PDU.

In another possible implementation manner, FIG. 22 is another schematic diagram of generating a second data packet of a CRC according to an embodiment of the present application. As shown in Figure 22, the terminal device can put together all the MAC subheaders in the second data packet (which can be regarded as a MAC PDU) as a MAC header, add a CRC to the MAC header at the top of the MAC PDU, and add a CRC to each MAC header.

The first sub-data block is used to indicate the position of the MAC sub-PDU including the second encoding block in the second data packet, and the second encoding block is a network encoding block. Therefore, the MAC layer can first verify that the CRC of the MAC header and the MAC CE are correct, and then perform the CRC check on the MAC SDU. After the network device receives the second data packet, the MAC layer submits the MAC SDU corresponding to the MAC header verified by the CRC to the RLC layer.

It should be understood that the step of adding CRC generation and other functions of network coding may be at the same protocol layer or at different layers. The above scenario applies to the following possible scenarios:

The sub-data packets of the two coding blocks are in one-to-one correspondence, and the check code is used to determine whether the sub-data packets including the second coding block are correctly received.

Specifically, for the description of the check code generated by the network device in the second data packet, you can refer to the description of the check code generated by the terminal device in the second data packet in S2001, and the execution body only needs to be replaced by the terminal device with the network Equipment, for the sake of brevity, this application will not repeat them here.

FIG. 28 is a schematic diagram of a data processing method 2800 provided by an embodiment of the present application. As shown in Figure 28, the method includes the following steps:

S2501, the network device determines the number of first coding blocks.

For example, the network device may determine the number of coding blocks in the first coding block according to the size of the resource to be scheduled, the size of the coding block, and the ratio of the to-be-coded block to the coding block, so that only one coding block group is generated for one transmission.

S2502, the network device sends seventh indication information to the terminal device, and correspondingly, the terminal device receives the seventh indication information from the network device.

For example, the network device may send seventh indication information to the terminal device, where the seventh indication information instructs the terminal device to schedule an uplink grant.

Specifically, the network device may send seventh indication information for scheduling uplink grants to the terminal device, and at the same time, the seventh indication information may indicate at least two of the following network coding parameters: N, each coding block in the first coding block The bit size of , and the ratio of N to M. Wherein, N is the number of blocks to be coded in a group of blocks to be coded, M is the number of coded blocks in the first coding block, and the first coding block is a coding block obtained by performing network coding on a set of blocks to be coded.

The network coding parameters defined or agreed in the protocol, the seventh indication information may only indicate one parameter in the network coding parameters, and the parameter is different from the network coding parameters predefined or agreed by the protocol.

It should be understood that the seventh indication information may be carried in the DCI of the network equipment in the scheduling of the terminal equipment uplink network coding transmission, or may be in the MAC CE associated with the path, which is not limited in this application. Wherein, when the seventh indication information is carried in the DCI in the PDCCH of the real-time scheduling data transmission, the DCI may indicate the network coding parameter for the uplink data that can be transmitted by the current DCI scheduling uplink grant.

If the network coding function is at other layers, such as the RLC layer or the new protocol layer, and the RLC layer or the new protocol layer receives the packet delivered by the lower layer, the network device can perform decoding at the other layer.

Based on the above solution, the network device can indicate the network coding parameters of the coding block, and generate the network coding parameters in real time, thereby avoiding dividing into multiple sets of coding packets and increasing the processing delay of coding and decoding.

FIG. 26 is a schematic diagram of a data processing method 2600 provided by an embodiment of the present application. As shown in Figure 26, the method includes the following steps:

S2601, the network device determines the number of first coding blocks.

For example, the network device may determine the number of coding blocks in the first coding block according to the size of the next scheduled resource, the size of the coding block, and the ratio of the block to be coded to the coding block, that is, only one coding block group is generated for one transmission. .

S2602, the network device sends the eighth indication information to the terminal device, and correspondingly, the terminal device receives the seventh indication information from the network device.

For example, the network device may send eighth indication information to the terminal device, where the first indication information indicates a network coding parameter.

Specifically, the network device may send eighth indication information to the terminal device, where the eighth indication information may indicate at least two of the following network coding parameters: N, the bit size of each coding block in the first coding block, and The ratio of N to M. Wherein, N is the number of blocks to be coded in a group of blocks to be coded, M is the number of coded blocks in the first coding block, and the first coding block is a coding block obtained by performing network coding on a set of blocks to be coded.

It should be understood that the eighth indication information may be carried in the DCI of the network device in the downlink network coding transmission of the scheduling terminal device, or may be in the MAC CE associated with the path, which is not limited in this application. Wherein, when the eighth indication information is carried in the DCI in the PDCCH of the real-time scheduled data transmission, the DCI may indicate the network coding parameter used for the downlink data of the current DCI scheduled transmission.

S2603, the network device generates a second data packet.

For example, the MAC layer of the network device indicates to the PDCP layer the number of encoding blocks of the first encoding block to be transmitted, and the PDCP layer determines the number of encoding blocks of the first encoding block to be transmitted according to the indication of the MAC layer, and submits it to the MAC layer. , the MAC layer multiplexes the coding blocks in the first coding block together to generate a second data packet, that is, a MAC PDU.

S2604, the network device sends the second data packet to the terminal device, and correspondingly, the terminal device receives the second data packet from the network device.

For example, after generating the second data packet, the network device may send the second data packet to the terminal device.

S2605, the terminal device decodes the second data packet.

For example, after receiving the second data packet, the terminal device performs decoding according to the coding parameter indicated by the PDCCH.

Specifically, the terminal device can parse the MAC PDU (second data packet) to obtain the MAC sub-PDU, and submit the MAC sub-PDU that has passed the CRC check to the RLC layer, and the RLC layer submits the PDCP PDU to the PDCP; the PDCP layer of the terminal device is based on The coding parameter determines the number of coding blocks Z in the current coding group, and puts the coding blocks less than or equal to Z into the decoding entity for decoding.

FIG. 27 is a schematic diagram of a data processing method 2700 provided by an embodiment of the present application. As shown in Figure 27, the method includes the following steps:

S2701, the network device sends third indication information to the terminal device, and correspondingly, the terminal device receives the third indication information from the network device.

For example, the network device may send third indication information to the terminal device, where the third indication information may instruct the terminal device to activate or deactivate the first channel.

Specifically, when the first channel is a wireless bearer, the third indication information may instruct the terminal device to convert a certain wireless bearer from a non-network coding operation to a network coding operation, or from a network coding operation to a non-network coding operation, that is, , instructs the terminal device to activate or deactivate the network coding function for a certain radio bearer. FIG. 28 is a schematic diagram of third indication information provided by an embodiment of the present application. As shown in Figure 28, the fourth field indicates a specific radio bearer. For example, the fourth field has a total of 8 bits. The position of one bit corresponds to the identifier of a data radio bearer configured with the network coding function. The value of the bit is 1 to activate the network coding function of the data radio bearer corresponding to this bit position. A value of 0 indicates that the network coding function of the data radio bearer corresponding to this bit position is deactivated. Bits 0 to 8 correspond to the ascending order (or descending order) of the size of the data radio bearer identifiers configured with the network coding function.

It should be understood that in the above solution, when the first channel is a logical channel, the radio bearer can be replaced with a logical channel, and the position of one bit can correspond to a group of logical channels identified by a data radio bearer configured with a network coding function. The first indication information may carry an identifier of a radio bearer and indication information of activating or deactivating network coding in a group of logical channels of the radio bearer.

It should also be understood that the network device may send the third indication information in the form of sending physical layer, PDCP layer control signaling, and MAC CE signaling, which is not limited in this application.

S2702, the terminal device activates the network coding function of the first channel.

For example, after receiving the third indication information, the terminal device may activate the network coding function of the first channel.

Specifically, after receiving the third indication information, the terminal device can activate or deactivate the network coding function of the designated first channel according to the first indication information, that is, enable or stop using the data generation band network coding for the first channel. format encoding package.

S2703, the terminal device generates a second data packet.

For example, the terminal device may generate a first data packet, and perform at least one processing on the first data packet to generate a second data packet. The first data packet includes fifth indication information, and the fifth indication information indicates that the first data packet includes a second encoding block, and the second encoding block is a network encoding block.

When the terminal device receives the third indication information from the MAC CE signaling, there may be retransmission on the air interface, and the network device and the terminal device have an ambiguous period for the effective time of the command. For example, the terminal device receives the deactivation signaling from the physical layer signaling, and the network coding packet that the terminal device may have generated is being sent or waiting to be sent over the air interface. Therefore, the network device does not know which packet received is a network encoded packet. However, the formats of the network coding package and the non-network coding package are different, and errors may occur if the non-network coding package is put into the network coding functional entity for decoding. Therefore, if the network coding function is at the PDCP layer, a field in the header of the PDCP PDU of the terminal device is required to indicate whether the PDCP SDU is a network coding packet, that is, including the second coding block.

Specifically, the terminal device may generate a first data packet (that is, a PDCP PDU), and indicate whether a certain PDCP SDU is a network coding packet through a field in the PDCP PDU.

If the network coding function is at the RLC layer, a field in the header of the RLC PDU to indicate whether the RLCSDU is a network coding packet.

If the network coding function is in the new network coding layer, a field in the header of the network coding layer PDU to indicate whether the RLCSDU is a network coding packet.

If the network coding function is at the SDAP layer, a field in the header of the SDAPPDU to indicate whether the SDAPDU is a network coding packet.

In a possible implementation manner, FIG. 29 is a schematic diagram of the first data packet provided by this embodiment of the present application. As shown in Figure 29, whether the PDCP SDU is a network coding packet can be represented by a 1-bit field in the PDCP header. For example, when the value of this bit is 1, it means that the PDCP SDU is a network coding packet (that is, including the second coding block); when the value of this bit is 0, it means that the PDCP SDU is a non-network coding packet ( That is, the second coding block is not included).

In another possible implementation manner, FIG. 30 is another schematic diagram of the first data packet provided by this embodiment of the present application. As shown in Figure 30, whether the SDAP SDU is a network coding packet can be represented by a 1-bit field in the NC header. For example, when the value of this bit is 1, it means that the SDAP SDU is a network coding packet (that is, including the second coding block); when the value of this bit is 0, it means that the SDAP SDU is a non-network coding packet ( That is, the second coding block is not included).

It should be understood that, in addition to the above cases, when a QoS flow of a service is mapped to a radio bearer, the terminal device performs network coding on a part of important service data, and the terminal device may not perform network coding on another part of unimportant service data. That is to say, a PDCP entity on the terminal device side may generate network coding packets and non-network coding packets, and a PDCP entity on the network device side may also receive network coding packets and non-network coding packets. Therefore, the PDCP PDU also needs a field to indicate whether the packet is a network encoded packet.

S2704, the terminal device sends the second data packet to the network device, and correspondingly, the network device receives the second data packet from the terminal device.

For example, the terminal device may send the second data packet to the network device.

Based on the above solution, through the first indication information, when the network coding function is activated to generate a network coding packet, the first data packet includes a network coding packet (ie, the second coding block); when the network coding function is deactivated to generate a non-network coding packet , the first data packet does not include the network coding packet (ie, the second coding block), which can improve the problem that the effective time of turning off or turning on the network coding function has an ambiguous period, which causes the problem that the data packet cannot be parsed in an accurate format.

FIG. 31 is a schematic diagram of a data processing method 3100 provided by an embodiment of the present application. As shown in Figure 31, the method includes the following steps:

S3101, the terminal device sends the network coding capability information to the network device, and correspondingly, the network device receives the network coding capability information from the terminal device.

S3102, the network device sends configuration information to the terminal device, and correspondingly, the terminal device receives the configuration information from the network device.

For example, the network device may send configuration information to the terminal device, where the configuration information includes at least one set of network coding parameters for the terminal device to perform network coding.

S3103a, the network device sends the first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information from the network device.

For example, the network device may send first indication information to the terminal device, where the first indication information indicates a network coding parameter for coding a group of blocks to be coded.

Specifically, for the description of the first indication information, reference may be made to the description of the first indication information in S903a. For the sake of brevity, this application will not repeat them here.
