Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence. In addition, the terms "including" and "having" and any variations of them are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those clearly listed. Those steps or units may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or equipment. In addition, the use of "and/or" in the present invention means at least one of the connected objects, such as A and/or B and/or C, which means that it includes A alone, B alone, C alone, and both A and B exist, Both B and C exist, A and C exist, and A, B, and C all exist in 7 cases.

In order to facilitate understanding, the following describes the network coding:

When performing network coding on the original data block (Source Data Packet), the network coding process may include the following steps:

Step 1. The originator divides the original data block.

The original data block can be evenly divided into K original data sub-blocks (Source Data Segment). The original data block can be expressed as:

P=[p ₁ p ₂ …p _K ]

Among them, p _k represents the Kth original data sub-block obtained by dividing the original data block P. Each element in p _k belongs to GF(2), GF is Galois Field, and GF(2) is the simplest finite field. In other words, _{each element in p k} only takes a value between 0 and 1, and the result of the operation is only 0 and 1, which is equivalent to only exclusive OR and multiplication.

It should be noted that, in practical applications, if the data length of the last original data sub-block is not enough, a zero-filling method can be used to make its data length equal to the data length of other original data sub-blocks. Exemplarily, assuming that the original data block is 01 00 10 0 and the value of K is 4, then:

P=[01 00 10 00]

Step 2: The sender generates a coding matrix.

The coding matrix is as follows:

It can be seen that the coding matrix M includes elements of K rows and N columns, where K is the number of original data sub-blocks obtained by dividing the original data block into equal parts, and N is the number of coded sub-blocks obtained by encoding K original data sub-blocks. Number. It should be understood that i in the coding matrix M is a positive integer less than or equal to K, and j is a positive integer less than or equal to N. In addition, a column of elements in the coding matrix M can be referred to as a column vector in the coding matrix M.

Define the sum of the elements in each column vector in the coding matrix M as the degree of freedom d, the formula is:

Since each column vector in the coding matrix M includes K elements, and each element in the coding matrix only takes a value between 0 and 1, therefore, the value of the degree of freedom of each column vector in the coding matrix M is greater than or Equal to 0, less than or equal to K. It should be understood that the values of the degrees of freedom of different columns may be the same or different.

The degree of freedom d obeys a specific distribution μ(d).

Among them, the calculation formula of τ(d) is:

The calculation formula of ρ(d) is:

further,

c is a suitable constant, and δ is the allowable failure probability.

It can be seen from the above that the distribution of degrees of freedom d is related to K, c, and δ.

The j-th column vector in the coding matrix M (that is, the j-th column vector from left to right in the coding matrix M) can be generated in the following way:

_{Determine the degrees of freedom d j of} the j-th column of vectors according to the distribution of degrees of freedom;

_{Randomly select d j} elements from the j-th column vector to take the value 1, and the remaining elements take the value 0.

Exemplarily, suppose that the value of K of the coding matrix M is 3 and the value of N is 4; the value of the degree of freedom of the first column vector of the coding matrix M is 1, and the value of the degree of freedom of the second column vector is 1. The value of the degree of freedom of the third column of vectors is 2, and the value of the degree of freedom of the fourth column of vectors is 2. In addition, the first element of the first column vector from top to bottom takes the value 1, the second and third elements of the third column vector from top to bottom take the value of 1, and the fourth column vector from the top The value of the first element and the second element below is 1. Then, in this case, the coding matrix M is:

Step 3: The sender encodes the original data block P to generate N coded sub-blocks.

C=PM=[c ₁ c ₂ …c _N ]

Among them, c _N is the N-th coded sub-block among the N coded sub-blocks. It can be known from the above formula that c _{N is determined} based on the original data block P and the Nth column vector in the coding matrix M. Therefore, it can be considered that the Nth coding sub-block has a corresponding relationship with the Nth column vector in the coding matrix M. It can be seen that each coding sub-block corresponds to a column vector in the coding matrix M.

The column vector corresponding to the coding sub-block may also be referred to as the number of the original data sub-block required to generate the coding sub-block. Since the column vectors corresponding to different coding sub-blocks are different column vectors of the coding matrix M, the numbers of the original data sub-blocks required to generate different coding sub-blocks are different.

Step 4: The receiving end decodes the received coded sub-block and restores the original data block.

Both the transmitting and receiving ends need to have the original data sub-block number (that is, the j-th column vector in the coding matrix M corresponding to the j-th coding sub-block) required to generate the coding sub-block. The receiving end combines the column vectors corresponding to the received coding sub-blocks into a matrix H. When H satisfies the condition of row full rank (rank(H)=K), it means that the currently received coding sub-block is sufficient to be restored Original data block P.

Take out the column vector that constitutes the full rank of the row and the corresponding coding sub-block from the matrix H to form a new coding matrix H′ and a new coding sub-block vector C′, so the original data can be obtained as:

[p ₁ p ₂ …p _K ]=C′H′ ^-1

The obtained original data sub-blocks are combined in order, that is, the original data block P is completely restored.

Using network coding for redundant transmission to improve the reliability of transmission and thus the transmission time delay, the required redundancy varies in different situations, but in general, the required redundancy is significantly less than 100%.

Network coding has the following characteristics:

1) The number of coded sub-blocks generated by the sender can theoretically be infinite;

2) The sender only needs to transmit a small number of redundant coded sub-blocks (Encoded Packet), so that the receiver can successfully restore the original data block;

3) The receiving end has no prejudice to the received coding sub-block (it is not required to receive a specific coding sub-block), only the matrix composed of the column vector corresponding to the received coding sub-block is in line with the full row Under the condition of the rank, the coded sub-block can be successfully decoded.

Therefore, if "network coding" is applied to the communication system, the receiving end only needs to feed back instructions to the transmitting end when the received coding sub-block meets certain conditions, instead of requiring every coding sub-block received in the past. Feedback to the sender can greatly reduce the delay. Therefore, the application of "network coding" to the communication system can effectively solve the problem of repeated transmission (such as automatic repeat reQuest (ARQ) or hybrid automatic retransmission request (Hybrid Automatic) in the air interface (Uu interface)). Repeat reQuest, HARQ)) to ensure the delay caused by the stability of the communication system. In addition, from the above feature 2), it can be seen that compared with carrier aggregation (CA) or dual connectivity (DC) packet duplication (Packet Duplication), the use of network coding to transmit data has lower redundancy, thus Can improve spectrum utilization.

The embodiment of the present invention adopts a network coding manner to realize the transmission of the data block from the first communication device to the second communication device. The embodiment of the present invention includes a data processing method applied to a first communication device, a data processing method applied to a second communication device, and a configuration method applied to a third communication device.

In a specific implementation, the first communication device can send the data block in the manner of network coding through the data processing method applied to the first communication device. Through the data processing method applied to the second communication device, the second communication device can recover the database sent by the first communication device in a network coding manner. Through the configuration method applied to the third communication device, the third communication device can configure the network coding parameters for the first communication device and the second communication device.

In practical applications, the communication device may be a network-side device or a terminal (also called User Equipment (UE)).

The embodiments of the present invention may include the following application scenarios.

Application scenario 1: Both the first communication device and the second communication device may be UEs. In other words, the data block can be transmitted between UEs in a network coding manner.

Application scenario 2: One of the first communication device and the second communication device is a UE, and the other communication device may be a base station. In other words, the data block can be transmitted between the UE and the base station in a network coding manner.

Application scenario 3: One of the first communication device and the second communication device is a UE, and the other communication device may be an intermediate point between the UE and the base station. In other words, the data block can be transmitted between the UE and the intermediate point in a network coding manner.

Application scenario 4: One of the first communication device and the second communication device is a base station, and the other communication device may be an intermediate point between the UE and the base station. That is to say, the data block can be transmitted between the base station and the intermediate point by means of network coding.

Scenario 5: Both the first communication device and the second communication device can be intermediate points between the UE and the base station. In other words, data blocks can be transmitted between intermediate points by means of network coding.

In practical applications, the UE can be a mobile phone, a tablet (Personal Computer), a laptop (Laptop Computer), a personal digital assistant (PDA), a mobile Internet device (Mobile Internet Device, MID), Wearable device (Wearable Device) or vehicle-mounted device, etc. The intermediate point between the UE and the base station may be a relay or an Integrated Access Backhaul (IAB) node, etc. In addition, the third communication device in the embodiment of the present invention may be a base station, an IAB node, a relay, or an access point, etc.

The embodiments of the present invention will be described in detail below.

Referring to FIG. 1, FIG. 1 is one of the flowcharts of the data processing method provided by the embodiment of the present invention. The data processing method shown in FIG. 1 can be applied to the first communication device.

As shown in Figure 1, the data processing method may include the following steps:

Step 101: Obtain network coding parameters.

Optionally, the acquiring network coding parameters includes: acquiring the network coding parameters according to at least one of the protocol agreement and the configuration information sent by the third communication device. That is to say, the network coding parameters may be agreed by the protocol and/or configured by the third communication device.

In specific implementation, the network coding parameters may include one or at least two parameters. It should be understood that in the case where the number of parameters included in the network coding parameter is different, the method of obtaining the network coding parameter may be different, and the specific description is as follows:

In the case that the network coding parameter includes only one parameter, the network coding parameter may be predetermined by a protocol or configured by a third communication device.

In the case that the network coding parameters include two or more parameters, the following implementation manners may be included:

Implementation manner 1: All parameters of the network coding parameters are configured by the third communication device.

Implementation manner 2: All parameters of the network coding parameters are predetermined by the protocol.

Implementation manner 3: The network coding parameters include a first part of parameters and a second part of parameters, the first part of parameters is predetermined by a protocol, and the second part of parameters is configured by a third communication device. In the third implementation manner, the specific expression forms of the first part of the parameters and the second part of the parameters may be determined according to actual conditions, which are not limited in the embodiment of the present invention.

Optionally, the network coding parameter corresponds to a target object, and the target object may correspond to any one of the following: a communication device, a media access control MAC entity of the communication device, a cell group, a logical channel, and a logical channel group. That is, the network coding parameter is the network coding parameter of the target object, and the network coding parameter serves the target object.

In practical applications, for the data block of a certain target object, the first communication device may perform network coding processing based on the network coding parameters corresponding to the target object.

Step 102: Generate N coded sub-blocks of the first data block through the target layer according to the network coding parameters, where N is a positive integer.

It should be noted that when N is 1, it may be considered that the target layer does not perform network coding on the first data block. When N is greater than 1, the target layer performs network coding on the first data block. The following mainly describes the case where N is greater than 1.

It can be known from the foregoing that the N coding sub-blocks are determined based on the original data block P and the coding matrix M. Therefore, in specific implementation, the target layer of the first communication device may first generate the first data block P and the coding matrix M according to the network coding parameters, and then use the first data block P and the coding matrix M to generate the first data block N coding sub-blocks.

Step 103: Send the N coded sub-blocks to the second communication device.

In the data processing method of this embodiment, the first communication device may generate N coding sub-blocks of the first data block through the target layer according to the acquired network coding parameters, and send the N coding sub-blocks to the second communication device , N is a positive integer. In this way, the second communication device can obtain the first data block based on the received coding sub-block. It can be seen that the embodiment of the present invention adopts network coding to realize the transmission of the first data block from the first communication device to the second communication device, thereby reducing the redundancy of data transmission while ensuring the reliability of data transmission, and thereby Can improve spectrum utilization.

Optionally, the network coding parameters include at least one of the following: L first parameters, L second parameters, third parameters, pseudo-random code seeds, L numbers, and L is a positive integer;

The first parameter is used to determine the number of divisions of the first data block;

The second parameter is used to determine the value of N;

To facilitate understanding, the above parameters are described below.

1) The first parameter

The first parameter may be used to determine the number of divisions of the first data block, that is, the value of K.

Optionally, the first parameter is any one of the following: the number of partitions of the first data block, and the maximum number of partitions of the first data block.

In specific implementation, when the first parameter is the number of divisions of the first data block, the first communication device may directly determine the value of the first parameter as the division of the first data block Number of copies. Exemplarily, assuming that the value of the first parameter is 5, the number of divisions of the first data block is 5, and the first communication device may equally divide the first data block into 5 data sub-blocks.

In the case that the first parameter is the maximum divisible number of shares of the first data block, the first communication device may select any positive integer less than or equal to the value of the first parameter as the first data block The number of splits. Exemplarily, assuming that the value of the first parameter is 5, the first communication device may determine that the number of divisions of the first data block is 3, and divide the first data block into 3 data sub-blocks on average.

2) The second parameter

The second parameter can be used to determine the value of N.

Optionally, the second parameter is any one of the following: the number of coding sub-blocks corresponding to the first data block, and the maximum number of coding sub-blocks corresponding to the first data block.

During specific implementation, when the second parameter is the number of coding sub-blocks corresponding to the first data block, the first communication device may directly determine the value of the second parameter as the value of N . Exemplarily, assuming that the value of the second parameter is 10, the value of N is 10. At this time, for the first data block, the first communication device can generate 10 coded sub-blocks, that is, the first data block The block corresponds to 10 coded sub-blocks.

In the case where the second parameter is the maximum number of coded sub-blocks corresponding to the first data block, the first communication device may select any positive integer less than or equal to the value of the second parameter as the value of N value. Exemplarily, assuming that the value of the second parameter is 10, the first communication device may determine that the value of N is 8. At this time, for the first data block, the first communication device may generate 8 coding sub-blocks, that is In other words, the first data block corresponds to 8 coding sub-blocks.

3) The third parameter

The third parameter can be used to determine the distribution of degrees of freedom.

It can be seen from the foregoing that the distribution of degrees of freedom d is related to K, c, and δ. The value of K can be determined by the first parameter, therefore, the third parameter can be used to determine c and δ.

4) Pseudo-random code seed

The pseudo-random code seed can be used to determine the column vector information corresponding to the coded sub-block.

It should be noted that, in practical applications, when the communication device determines the column vector information corresponding to the coding sub-block according to the pseudo-random code seed, it also needs to combine the distribution of the degrees of freedom d. That is, the pseudo-random code seed determines the column vector information corresponding to the coded sub-block based on the distribution of the degrees of freedom d.

In the first implementation manner, the column vector information may include the degree of freedom of the column vector and the number of the element whose value is 1 in the column vector.

In the first implementation manner, the pseudo-random code seed may include a first pseudo-random code seed and a second pseudo-random code seed, wherein the first pseudo-random code seed is used to generate a column vector corresponding to the coding sub-block. Degree of freedom, the second random code seed is used to generate the number of the element whose value is 1 in the column vector corresponding to the coding sub-block.

It can be seen from the above content that the roles of the first pseudorandom code seed and the second pseudorandom code seed are different. Therefore, the first pseudorandom code seed and the second pseudorandom code seed can be regarded as different types. The pseudo-random code seed.

During specific implementation, optionally, different types of pseudo-random code seeds can have different manifestations. For example, the first pseudo-random code seed can be represented as Arabic numerals, and the second pseudo-random code seed can be represented as English letters. In this way, the communication device can distinguish between different types of pseudo-random code seeds. Of course, the foregoing manner is only an example. In practical applications, different types of pseudo-random code seeds may also be distinguished in other manners, which is not limited in the embodiment of the present invention.

In specific implementation, the first pseudo-random code seed can generate N values, each value represents the value of the degree of freedom of a column vector; the second pseudo-random code seed can generate N groups of values, each group of values includes V values, the value of V is equal to the number of elements with the value of 1 in the column vector, and each value in the V values represents the number of the element with the value of 1 in the column vector.

Exemplarily, when the value of K is obtained as 5, it is assumed that the value sequence generated by the first pseudo-random code seed is 2; 3; 5; 5; 1; 2, the second pseudo-random code The value sequence generated by the seed is: 1, 2; 1, 3, 5; 1, 2, 3, 4, 5; 1, 2, 3, 4, 5; 3; 4, 5.

Then, the first communication device may determine, based on the first pseudorandom code seed, that the value of N is 6, the coding matrix includes 6 column vectors, and the degree of freedom of the first column vector is 2, and the degree of freedom of the second column vector is 2. Is 3, the degree of freedom of the third column vector is 5, the degree of freedom of the fourth column vector is 5, the degree of freedom of the fifth column vector is 1, and the degree of freedom of the sixth column vector is 2.

The second communication device may determine, based on the second pseudo-random code seed, that the values of the first element and the second element in the first column vector are 1, and the remaining elements are 0; the first element in the first column vector The value of one element, the third element, and the fifth element is 1, and the value of the remaining elements is 0; the value of all elements in the third column vector and the fourth column vector is 1; the value of the fifth column vector is The value of the third element of is 1 and the value of other elements are 0; the value of the fourth element and the fifth element of the sixth column vector is 1, and the value of the remaining elements is 0.

Based on the above content, the first communication device can generate a coding matrix M:

Assuming that the first data block is 11001, based on the acquired value of K of 5, the first communication device can generate P=[1 1 0 0 1].

In this way, the first communication device generates 6 coding sub-blocks based on the first data block:

It should be noted that, for the first pseudo-random code seeds with different values, the generated N values are different, but the N values all obey the distribution of the degree of freedom d.

Exemplarily, assuming that d obeys the normal distribution, and taking the value according to the distribution probability of d, the value of 1; 3; 5; 5; 2 can be obtained.

If the first pseudo-random code seed is 2, the value sequence that can be obtained based on the first pseudo-random code seed is 2; 3; 5; 5; 1.

If the first pseudo-random code seed is 3, the value sequence that can be obtained based on the first pseudo-random code seed is 2; 3; 1; 2; 1.

It can be seen that the first pseudo-random code seed can be used to determine the degree of freedom corresponding to the coded sub-block.

Similarly, for the second pseudo-random code seeds with different values, the generated N sets of values can be different.

In the second implementation manner, the column vector information may be a column vector.

In the second implementation manner, the pseudo-random code seed can be used to generate N column vectors. In this way, the first communication device can generate an encoding matrix M based on the generated N column vectors; in addition, the first communication device can determine the value of K based on the number of elements included in any column vector of the generated N column vectors, Generate the first data block P. After that, N coded sub-blocks of the first data block are generated.

It can be seen that in the case that the network coding parameters include the pseudo-random code seed, the second communication device can autonomously determine the column vector corresponding to the coding sub-block based on the pseudo-random code seed, which is compared with the second communication device based on the pseudo-random code seed. The instruction of the first communication device determines the column vector corresponding to the coding sub-block, which can reduce the signaling overhead between the first communication device and the second communication device.

4) Number

The number is the number of the network coding parameter combination, and can be used to indicate the network coding parameter combination. The network coding parameter combination may include at least two of the following: a first parameter, a second parameter, and a third parameter.

In practical applications, the first communication device may store P network coding parameter combinations. The first communication device may determine the L network coding parameter combinations in the P network coding parameter combinations based on the L numbers.

It is assumed that the network coding parameter combination includes the first parameter, the second parameter, and the third parameter.

Then, when L is 1, the first communication device can determine the values of K, N, c, and δ.

In the case that L is greater than 1, the first communication device can autonomously select the target number from the L numbers, and then determine the values of K, N, c, and δ according to the target encoding parameter combination corresponding to the target number.

It can be seen from the above content that the value of K can be obtained in any of the following ways:

Obtaining method 1: Obtain the value of K according to the first parameter.

The second acquisition method is to acquire the value of K according to the number of the network coding parameter combination, and the network coding parameter combination includes the first parameter.

The value of N can be obtained in any of the following ways:

The third acquisition method is to acquire the value of N according to the second parameter.

The fourth method of obtaining is to obtain the value of N according to the number of the network coding parameter combination, and the network coding parameter combination includes the second parameter.

The values of c and δ can be obtained according to the third parameter.

In this embodiment, the purpose of acquiring the network coding parameters by the first communication device is to generate a first data block P and generate a coding matrix M, and then generate first data according to the generated first data block P and coding matrix M. N coded sub-blocks of the block.

For the first data block P, the first communication device can generate the first data block P after obtaining the value of K.

For the coding matrix M, it can be generated according to K, N, c, and δ.

In summary, the network coding parameters in any of the following manifestations can enable the first communication device to generate the first data block P and the coding matrix M, and then generate the first data block P and the coding matrix M according to the generated first data block P and the coding matrix M. N coded sub-blocks of a data block.

Expression form 1: The network coding parameters include L first parameters, L second parameters, and third parameters.

For the network coding parameter of the first form of expression, when L is greater than 1, the first communication device may select a first parameter from the L first parameters, and then determine the value of K based on the first parameter; A second parameter is selected for the L second parameters, and then the value of N is determined based on the second parameter.

Optionally, when L is greater than 1, the L second parameters correspond to the L first parameters. Specifically, the L second parameters and the L first parameters have a one-to-one correspondence. In this way, the first communication device can only select the first parameter or the second parameter, and then can determine the other one of the first parameter and the second parameter based on the above-mentioned corresponding relationship, thereby simplifying the selection operation of the first communication device .

Optionally, when L is greater than 1, the number of the third parameter is 1 or Q, and Q is an integer greater than 1 and less than or equal to L.

Further, when the number of the third parameters is Q, the Q third parameters satisfy at least one of the following:

The Q third parameters correspond to the L first parameters;

The Q third parameters correspond to the L second parameters.

In the case where the Q third parameters correspond to the L first parameters, if the value of Q is less than the value of L, then one of the L first parameters may correspond to the Q third parameters A parameter of can also correspond to two or more of the Q third parameters; if the value of Q is equal to the value of L, then one of the L first parameters corresponds to the Q third parameters One of the parameters. In this case, the first communication device may determine the third parameter based on the determined first parameter.

Similarly, when the Q third parameters correspond to the L second parameters, if the value of Q is less than the value of L, then one of the L second parameters can correspond to the Q One of the three parameters can also correspond to two or more of the Q third parameters; if the value of Q is equal to the value of L, then one of the L second parameters corresponds to the Q third parameter. One of the three parameters. In this case, the first communication device may determine the third parameter based on the determined second parameter.

Expression form 2: The network coding parameters include L numbers.

For the network coding parameters of the second expression form, in the case that the network coding parameter combination includes the first parameter, the second parameter, and the third parameter, the network coding parameter may only include L numbers.

In the case that the network coding parameter combination includes the first parameter and the third parameter, the network coding parameter may further include L second parameters.

In the case that the network coding parameter combination includes the first parameter and the second parameter, the network coding parameter may further include a third parameter.

In the case that the network coding parameter combination includes the second parameter and the third parameter, the network coding parameter may further include L first parameters.

For the network coding parameters of the second expression form, when L is greater than 1, the first communication device may first select one of the L parameters, and then generate N coding sub-blocks based on the selected parameters.

It should be noted that, in practical applications, optionally, the value of N determined by the first communication device may be greater than the value of K, so as to improve the reliability of data block transmission. Exemplarily, suppose that the network coding parameters include a first parameter and a second parameter, the first parameter is the maximum divisible number of the first data block, and the second parameter is the corresponding value of the first data block For the maximum number of coding sub-blocks, the values of the first parameter and the second parameter are both 10. Then, the value of K determined by the first communication device may be 3, and the value of N may be 6.

The above-mentioned network coding parameters are only examples. Any data block that can cause the first communication device to generate the first data block P and the coding matrix M, and then generate the first data block according to the generated first data block P and the coding matrix M The network coding parameters of the N coding sub-blocks all fall into the protection scope of the embodiment of the present invention.

In specific implementation, when generating the coding matrix M, the first communication device may first determine the distribution of the degrees of freedom d according to K, c, and δ, and then may generate the coding matrix M according to the distribution of the degrees of freedom d, K and N.

After determining the distribution of degrees of freedom d, K, and N, in order to generate the encoding matrix M, it is necessary to determine the degrees of freedom corresponding to the N column vectors in the encoding matrix, and the elements of the N column vectors with the value of 1 Number.

In the first embodiment, the first communication device can autonomously determine the degrees of freedom corresponding to the N column vectors in the coding matrix according to the distribution of the degrees of freedom d, and the number of the element whose value is 1 in each of the N column vectors. .

In the second embodiment, after determining the distribution of the degrees of freedom d, the first communication device can generate the degrees of freedom of N column vectors based on the pseudo-random code seed, and the values of the elements of the N column vectors whose value is 1 in each column vector. Numbering.

It can be understood that, in the case where the first communication device determines the degrees of freedom corresponding to the N column vectors in the coding matrix according to the second embodiment, and the number of the element whose value is 1 in each of the N column vectors The network coding parameters of the above-mentioned expression form 1 and expression form 2 may also include a pseudo-random code seed.

It should be noted that, for the first embodiment, since the degrees of freedom corresponding to the N column vectors in the coding matrix, and the number of the element whose value is 1 in each column vector of the N column vectors are determined independently by the first communication device Therefore, in order for the second communication device to decode successfully, the first communication device should instruct the second communication device to determine the degree of freedom of the N column vectors in the coding matrix determined by it, and the value of each column vector in the N column vectors The number of the element that is 1.

For the second embodiment, since the degrees of freedom corresponding to the N column vectors in the coding matrix, and the number of the element whose value is 1 in each column vector of the N column vectors are determined by the pseudo-random code seed, the second communication The device can determine the degrees of freedom corresponding to each of the N column vectors in the coding matrix by obtaining the pseudo-random code seed, and the number of the element whose value is 1 in each column vector of the N column vectors, without the instruction of the first communication device. Reduce the signaling overhead between the first communication device and the second communication device.

The header of the coding sub-block will be described below.

Optionally, when L is 1, the header of the first coding sub-block in the N coding sub-blocks includes a first set field, and the first set field includes at least one of the following:

The first field is used to indicate the number of divisions of the first data block;

The second field is used to indicate the number of the first data block;

The third field is used to indicate the number of the first coding sub-block;

The fourth field is used to indicate the column vector information corresponding to the first coding sub-block;

The fifth field is used to indicate the data length of the first coding sub-block.

Optionally, when L is greater than 1, the header of the first coding sub-block in the N coding sub-blocks includes a second set field, and the second set field includes at least one of the following:

The sixth field is used to indicate a fourth parameter, and the fourth parameter has a corresponding relationship with the number of divisions of the first data block;

The seventh field is used to indicate the target number among the L numbers;

The second field is used to indicate the number of the first data block;

The third field is used to indicate the number of the first coding sub-block;

To facilitate understanding, the above domains are described below.

1) The first domain

The first field is used to indicate the number of divisions of the first data block, that is, the value of K. It can be seen that the first communication device can explicitly indicate the value of K by carrying the first field in the header of the coding sub-block.

2) The second domain

The second field is used to indicate the number of the first data block. In practical applications, the first communication device may send two or more data blocks to the second communication device. In this case, the first communication device sends coded sub-blocks with different data blocks. Therefore, in order to facilitate the second communication device to accurately identify the coding sub-block corresponding to the same data block, the first communication device may carry a second field in the header of each coding sub-block to indicate the number of the data block corresponding to the coding sub-block .

3) Third domain

The third field is used to indicate the number of the first coding sub-block. In practical applications, the value of N is generally greater than 1. It can be seen from the foregoing that the column vectors in the coding matrix corresponding to different coding sub-blocks are different. Therefore, in order to facilitate the second communication device to accurately determine the column vector corresponding to each coding sub-block, the first communication device may carry a third field in the header of each coding sub-block to indicate the number of the coding sub-block.

4) The fourth domain

The fourth field is used to indicate column vector information corresponding to the first coding sub-block. Specifically, the fourth field may be used to indicate the degree of freedom of the column vector corresponding to the first coding sub-block, and the number of the element in the column vector whose value is 1. In this way, the second communication device can obtain the column vector corresponding to the first coding sub-block based on the fourth domain and the value of K.

5) Fifth domain

6) The sixth domain

The sixth field is used to indicate a fourth parameter, and the fourth parameter has a corresponding relationship with the number of divisions of the first data block. In practical applications, the protocol may agree on the correspondence between the fourth parameter and K. For example, if the value of the fourth parameter is 1, the value of K corresponding to the fourth parameter is 4; If the value is 2, the value of K corresponding to the fourth parameter is 5. In this way, the second communication device can determine the value of K based on the fourth parameter indicated by the sixth domain and the foregoing corresponding relationship.

7) The seventh domain

The seventh field is used to indicate a target number in the L numbers, and the target number indicates a network coding parameter combination in P network coding parameter combinations. It should be understood that the target network coding parameter combination corresponding to the target number is a parameter used by the first communication device to generate the N coding sub-blocks. In this way, the second communication device can determine the value of K based on the target number indicated by the seventh field.

It can be seen from the above that the first, sixth, and seventh fields can all be used to determine the value of K. It can be seen that the first communication device can carry the first and sixth fields in the header of the coding sub-block. Or the seventh field, which explicitly indicates the value of K.

It should be noted that in other implementation manners, the first communication device may also implicitly indicate the value of K. Optionally, when L is greater than 1, the size of the first coding sub-block in the N coding sub-blocks corresponds to any one of the following:

The number of partitions of the first data block;

The number of the network coding parameter combination corresponding to the number of divisions of the first data block.

In this optional implementation manner, the value of K is different, and the size of the coding sub-block is different. Specifically, the value of K may be negatively related to the size of the coding sub-block, that is, the smaller the value of K, the larger the size of the coding sub-block, and the smaller it is anyway. In practical applications, the sizes of different coded sub-blocks corresponding to the same data block may be the same. Therefore, the first communication device may determine the value of K corresponding to the data block based on the size of any coding sub-block corresponding to the same data block.

It should be understood that the foregoing implicit indication manner is only an example, and other implicit indication manners of the value of K may all fall within the protection scope of the embodiment of the present invention.

In this embodiment, when multiple optional network coding layer parameters are defined in the protocol or the network (pre-)configured, such as L first parameters, the header of the network coding layer or the sub-label of the network coding sublayer The subheader may explicitly indicate the parameters used, or the network coding layer parameters may be implicitly indicated.

It should be noted that the first coding sub-block may be understood as any coding sub-block of the N coding sub-blocks.

In addition, the headers of different coded sub-blocks in the N coded sub-blocks may be the same or different. Exemplarily, since one data block corresponds to one K value, one coding sub-block corresponding to the data block may carry the first domain to indicate the K value, and other coding sub-blocks corresponding to the data block may not carry the first domain.

In practical applications, it can be known from the foregoing that if the second communication device determines to obtain the column vector corresponding to the received coding sub-block through the foregoing embodiment 1, the header of the coding sub-block may include the fourth field. If the second communication device determines to obtain the column vector corresponding to the received coding sub-block through the foregoing implementation manner 2, the header of the coding sub-block may not include the fourth field, so that the first communication device and the second communication can be reduced. Signaling overhead between devices.

It can be known from the foregoing that the first communication device can perform network coding on the data block through the target layer. In practical applications, the target layer may be:

The first layer in the Radio Access Network (RAN) protocol stack, or,

The second layer in the RAN protocol stack;

Among them, the first layer can be regarded as an existing layer in the RAN protocol stack, such as the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the backhaul from The Backhaul Adaptation Protocol (BAP) layer, the Medium Access Control (MAC) layer, and the physical (PHY) layer; the second layer can be regarded as a newly added layer in the RAN protocol stack.

The following describes the cases where the target layer is the first layer and the target layer is the second layer.

Case 1: The target layer is the first layer.

Optionally, the first layer includes a network coding sublayer, a first target indication field is generated by the network coding sublayer, and the first target set field is the first set field or the second set field .

In case 1, the first communication device performs network coding on the data block through the network coding sublayer of the first layer to generate coded sub-blocks.

Since the target layer is an existing layer, optionally, the header of the first coding sub-block may further include a third aggregation field, and the third aggregation field is divided by the network coding from the target layer. Other sub-layers other than sub-layers are generated.

In this case, the header of the coded sub-block includes the first target set field and the third set field. The first target set field can be regarded as the first sub-header of the coded sub-block, and the third set field can be regarded as the coded sub-block. The second sub-header. The third set field is generated by other sublayers in the first layer except the network coding sublayer. The second subheader can be regarded as the header of the original first layer. For example, if the first layer is PDCP layer, the second sub-header can be regarded as the header of the PDCP layer.

Further, the third collection domain is located before the first target collection domain, or the third collection domain is located after the first target collection domain.

In the case that the third collection domain is located before the first target collection domain, the first layer first performs network coding processing to generate the first target collection domain, and then performs the existing processing of the first layer to generate the third collection domain .

In the case that the third collection domain is located after the first target collection domain, the first layer first performs the existing processing of the first layer to generate the third collection domain, and then performs network coding processing to generate the first target collection domain .

Case 2: The target layer is the second layer.

In the second case, the target layer is an independent layer. Therefore, the header of the coding sub-block may only include the first target set field.

In practical applications, the target layer can be set between any two existing layers of the RAN protocol stack.

Optionally, the network coding layer satisfies any one of the following:

The network coding layer is set between the PDCP layer and the radio link control RLC layer;

The network coding layer is set between the PDCP layer and the backhaul adaptive protocol BAP layer.

Step 203: In a case where the first matrix is a row full-rank matrix, restore the first data block according to the first matrix and the M coded sub-blocks.

In specific implementation, when the second communication device executes the above step 201, the number of received coding sub-blocks of the first data block may be greater than or equal to M.

In the case that the number of coded sub-blocks of the received first data block may be greater than M, the second communication device may select M coded sub-blocks from the received coded sub-blocks, and determine the corresponding code sub-blocks of the M coded sub-blocks. Whether the matrix generated by the M column vectors is a row-full-rank matrix, until the coding sub-blocks that make the row of the first matrix full-rank are found.

The restoring the first data block according to the first matrix and the M coding sub-blocks may specifically include: obtaining the first data according to the first matrix and the M coding sub-blocks The data sub-blocks corresponding to the blocks are then combined in order to obtain the first data block.

In order to avoid repeating the description, it will not be repeated here.

It should be noted that the various optional implementation manners introduced in the embodiments of the present invention may be implemented in combination with each other or may be implemented separately if they do not conflict with each other, which is not limited in the embodiments of the present invention.

To facilitate understanding, examples are described as follows:

Network Coding (NWC) can be a completely new protocol layer or an extended sublayer of a certain layer in the existing protocol stack. The present invention designs network coding for protocol design and related signaling design when RAN data transmission, including "network coding parameter configuration" and "NWC header design". The configuration can be configured according to communication equipment or according to communication equipment. The MAC entity, cell group, or LCH/LCG can be configured to configure a consistent network code, or it can be configured with multiple network codes to provide flexibility to choose according to the situation.

For the sake of brevity, in the detailed description below, it is assumed that the network coding is configured according to LCH (i.e. per LCH). However, these solutions can be extended and applied to the case of network coding configuration according to the MAC entity, cell group, or LCG of the communication device, and these applications are also included in the protection scope of the present invention.

As an example, Figure 4 shows the flow chart of the network control unit that performs network coding configuration according to LCH; Figure 5 shows the flow chart of the origination of network coding configuration according to LCH; Figure 6 shows the network coding configuration according to LCH The flow chart of the configuration of the receipt.

Figure 4 includes the following steps:

Step 401: The network control unit configures the originating LCH network coding parameters.

Step 402: The network control unit configures the receiving end LCH network coding parameters.

In practical applications, the sending end LCH network coding parameters and the receiving end LCH network coding parameters configured by the network control unit may be the same or different.

Figure 5 includes the following steps:

Step 501: Receive an LCH network coding parameter of the communication device.

Step 502: Determine the header format of the coded sub-block.

Step 503: Perform network coding processing on the data block of the LCH according to the network coding parameter of the LCH and the header format of the coding sub-block to generate a coding sub-block.

Step 504: Send the coded sub-block generated by the LCH.

Figure 6 includes the following steps:

Step 601: Receive an LCH network coding parameter of the communication device.

Step 602: Determine the header format of the coded sub-block.

Step 603: Receive the coding sub-block of the LCH.

Step 604: According to the network coding parameters of the LCH and the header format of the coding sub-block, decode the received coding sub-block of the LCH, and restore the data block.

It should be noted that, in some implementation manners, the receiving end may directly decode the received encoding sub-block of the LCH according to the header format of the encoding sub-block to restore the data block. Therefore, in these embodiments, the network control unit may not perform step 401, and the receiving end may not perform step 604.

It should be noted that the header format of the coding sub-block may be pre-arranged by the protocol. Specifically, the header format of the coding sub-block may include at least one of the aforementioned first to seventh fields.

"Network coding matrix number": used to indicate the K value actually selected from the L candidate values (using a "network coding matrix index" in the header to indicate the selected K value, if the index indication method is used, then it is required Protocol definition, or the relationship between the value of K and Index when the network is configured, for example, there is a list of K values: l=1 corresponds to K=4; l=2 corresponds to K=5);

"Network coding parameter combination number": used to indicate the value of the number of copies K actually taken for the original data to be divided into equal parts;
