Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," and the like in the description herein are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Further, as used herein, "and/or" means at least one of the connected objects, e.g., a and/or B and/or C, means 7 cases including a alone, B alone, C alone, and both a and B present, B and C present, a and C present, and A, B and C present.

For ease of understanding, the following description of network coding:

when network coding is performed on an original Data block (Source Data Packet), the network coding process may include the following steps:

the method comprises the following steps that an original data block is divided by a sending end.

An original Data block may be divided equally into K original Data sub-blocks (Source Data segments). The original data block may be represented as:

P＝[p₁ p₂ … p_K]

wherein p is_kWhich represents the kth original data subblock resulting from dividing the original data block P. p is a radical of_kEach element in (1) belongs to GF (2), which is a Galois Field (Galois Field), GF (2) being the simplest finite Field. That is, p_kEach element in the data is only valued in 0 and 1, and the result obtained by 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 0 complementing mode may be adopted, so that the data length of the last original data sub-block is equal to the data lengths of other original data sub-blocks. For example, assuming that the original data block is 0100100 and K takes a value of 4, then:

P＝[01 00 10 00]

and step two, the transmitting end generates a coding matrix.

The coding matrix is as follows:

it can be seen that the coding matrix M includes K rows and N columns of elements, where K is the number of original data sub-blocks obtained by equally dividing the original data block, and N is the number of coding sub-blocks obtained by coding the K original data sub-blocks. It is to be understood that i in the encoding 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 may be referred to as a column vector in the coding matrix M.

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

since each column vector in the coding matrix M includes K elements, and each element in the coding matrix is only valued in 0 and 1, the degree of freedom of each column vector in the coding matrix M is greater than or equal to 0 and less than or equal to K. It should be understood that the degrees of freedom for different columns may be equal in value or different.

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

Wherein, the calculation formula of tau (d) is as follows:

the formula for calculating ρ (d) is:

further, the air conditioner is provided with a fan,

c is a constant (a susitable constant), and δ is an allowable failure probability (allowability).

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

The jth column vector in the coding matrix M (i.e., the jth column vector from left to right in the coding matrix M) can be generated as follows:

determining the degree of freedom d of the jth column vector according to the distribution of the degree of freedom_j；

Randomly selecting d from jth column vector_jThe value of each element is 1, and the value of the other elements is 0.

For example, assume that K of the coding matrix M takes a value of 3 and N takes a value of 4; the degree of freedom of the first column vector of the coding matrix M is 1, the degree of freedom of the second column vector is 3, the degree of freedom of the third column vector is 2, and the degree of freedom of the fourth column vector is 2. In addition, the value of the first element of the first column vector from top to bottom is 1, the values of the second element and the third element of the third column vector from top to bottom are 1, and the values of the first element and the second element of the fourth column vector from top to bottom are 1. Then, in this case, the coding matrix M is:

and step three, the original data block P is coded by the transmitting end to generate N coding sub-blocks.

C＝PM＝[c₁ c₂ … c_N]

Wherein, c_NIs the nth of the N encoded sub-blocks. From the above formula, c_NIs determined based on the original data block P and the nth column vector in the coding matrix M. Therefore, it can be seen 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 encoded sub-block corresponds to a column vector in the encoding matrix M.

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

And step four, the receiving end decodes the received coding sub-block and restores the original data block.

Both the transmitting and receiving ends need to have the original data sub-block number (i.e. the jth column vector in the coding matrix M corresponding to the jth coding sub-block) needed for generating the coding sub-block. The receiving end combines the column vectors corresponding to the received encoded sub-blocks into a matrix H, and when H satisfies the condition of full rank (H) ═ K), it means that the currently received encoded sub-blocks are enough to recover the original data block P.

Taking out the column vectors forming the full rank of the row and the corresponding coding sub-blocks in the matrix H to form a new coding matrix H 'and a new coding sub-block vector C', so that the original data can be obtained as follows:

[p₁ p₂ … p_K]＝C′H′

and combining the obtained original data sub-blocks in sequence, namely completely recovering to obtain an original data block P.

The network coding is used for redundant transmission to improve the reliability of transmission and further improve the transmission delay, the required redundancy is different under different conditions, but generally, the required redundancy is obviously less than 100%.

Network coding has the following characteristics:

1) the number of the code sub-blocks generated by the originating terminal can theoretically be infinite;

2) the transmitting end only needs to transmit a small number of redundant coded sub-blocks (Encoded packets), so that the receiving end can successfully recover the original data blocks;

3) the receiving end has no prejudice to the received coding sub-blocks (a certain specific coding sub-block is not required to be received), and the coding sub-blocks can be successfully decoded only when a matrix formed by column vectors corresponding to the received coding sub-blocks meets the condition of full row rank.

Therefore, if the 'network coding' is applied to a communication system, the receiving end only needs to feed back the indication to the transmitting end when the received coding sub-block meets a certain condition, and does not need to feed back to the transmitting end every time one coding sub-block is received like the prior art, so that the time delay can be greatly reduced. Therefore, the "network coding" is applied to the communication system, and the problem of delay caused by ensuring the stability of the communication system by using repeated transmission (for example, using Automatic Repeat reQuest (ARQ) or Hybrid Automatic Repeat reQuest (HARQ)) in the air interface (Uu interface) can be effectively solved. Further, from the above characteristic 2): compared with Carrier Aggregation (CA) or Dual Connectivity (DC) Packet replication, the redundancy of data transmission using network coding is lower, and thus the spectrum utilization rate can be improved.

The embodiment of the invention realizes the transmission of the data block from the first communication equipment to the second communication equipment by adopting a network coding mode. The embodiment of the invention comprises a data processing method applied to first communication equipment, a data processing method applied to second communication equipment and a configuration method applied to third communication equipment.

In a specific implementation, the first communication device may transmit the data block in a network coding manner by using the data processing method applied to the first communication device. By the data processing method applied to the second communication device, the second communication device can restore the database sent by the first communication device in a network coding mode. The third communication device may configure the network coding parameters for the first communication device and the second communication device by a configuration method applied to the third communication device.

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

Embodiments of the invention may include the following application scenarios.

The application scenario one, the first communication device and the second communication device may all be UEs. That is, the UE may transmit the data block by network coding.

In the second application scenario, one of the first communication device and the second communication device is a UE, and the other communication device may be a base station. That is, the UE and the base station may transmit data blocks in a network coding manner.

In the third application scenario, 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. That is, the UE and the intermediate point may transmit the data block in a network coding manner.

In the application scenario four, 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, the data block may be transmitted between the base station and the intermediate point by using network coding.

It should be appreciated that scenario five, the first communication device and the second communication device may all be intermediate points between the UE and the base station. That is, the data blocks may be transmitted between the intermediate points in a network coding manner.

In practical applications, the UE may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device. An intermediate point between the UE and the base station may be an Integrated Access Backhaul (IAB) node or the like. In addition, the third communication device in the embodiment of the present invention may be a base station, an IAB node, a relay, an access point, or the like.

The following specifically describes examples of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a data processing method according to an embodiment of the present invention. The data processing method shown in fig. 1 may be applied to the first communication device.

As shown in fig. 1, the data processing method may include the steps of:

step 101, obtaining network coding parameters.

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

In a specific implementation, the network coding parameter may include one or at least two parameters. It should be understood that, when the number of the parameters included in the network coding parameter is different, the network coding parameter may be obtained in different manners, which is specifically described as follows:

in case the network coding parameter comprises only one parameter, the network coding parameter may be configured by a protocol subscription or a third communication device.

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

in the first implementation manner, all the parameters of the network coding parameters are configured by the third communication device.

In the second implementation mode, all the parameters of the network coding parameters are predetermined by a protocol.

In a third implementation manner, the network coding parameters include a first partial parameter and a second partial parameter, the first partial parameter is predetermined by a protocol, and the second partial parameter is configured by a third communication device. In the third implementation manner, specific expressions of the first partial parameter and the second partial parameter may be determined according to actual situations, which is 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 items: communication equipment, and a Media Access Control (MAC) entity, a cell group, a logical channel and a logical channel group of the communication equipment. That is, the network coding parameter is a network coding parameter of the target object, and the network coding parameter serves the target object.

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

And 102, generating N coding sub-blocks of the first data block through the target layer according to the network coding parameters, wherein N is a positive integer.

It should be noted that, in the case that N is 1, the target layer may not perform network coding on the first data block. In the case that N is greater than 1, the target layer network encodes the first data block. The following description will be mainly made for the case where N is larger than 1.

As can be seen from the foregoing, the N encoded sub-blocks are determined based on the original data block P and the encoding matrix M. Therefore, in a 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 generate the N coding sub-blocks of the first data block by using the first data block P and the coding matrix M.

And 103, sending the N coding sub-blocks to a second communication device.

In the data processing method of this embodiment, the first communication device may generate, according to the obtained network coding parameter, N coding sub-blocks of the first data block through the target layer, and send the N coding sub-blocks to the second communication device, where N is a positive integer. In this way, the second communication device may retrieve the first data block based on the received encoded sub-block. Therefore, the embodiment of the invention realizes the transmission of the first data block from the first communication device to the second communication device by adopting a network coding mode, thereby reducing the redundancy of data transmission and further improving the frequency spectrum utilization rate under the condition of ensuring the reliability of data transmission.

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

the first parameter is used for determining the number of the divided parts of the first data block;

the second parameter is used for determining the value of N;

the third parameter is used to determine a distribution of degrees of freedom.

For convenience of understanding, the above parameters are described below.

1) First parameter

The first parameter may be used to determine the number of divided parts of the first data block, i.e., 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 partitionable partitions of the first data block.

In a specific implementation, when the first parameter is the number of divided parts of the first data block, the first communication device may directly determine the value of the first parameter as the number of divided parts of the first data block. For example, assuming that the value of the first parameter is 5, the number of divided parts of the first data block is 5, and the first communication device may divide the first data block into 5 data sub-blocks on average.

When the first parameter is the maximum divisible number of the first data block, the first communication device may select any positive integer smaller than or equal to a value of the first parameter as the divisible number of the first data block. For example, assuming that the value of the first parameter is 5, the first communication device may determine that the number of divided parts of the first data block is 3, and averagely divide the first data block into 3 data sub-blocks.

2) Second parameter

The second parameter may be used to determine a value of N.

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

In a specific implementation, when the second parameter is the number of the 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. For example, assuming that the value of the second parameter is 10, the value of N is 10, and at this time, for the first data block, the first communication device may generate 10 encoded sub-blocks, that is, the first data block corresponds to 10 encoded sub-blocks.

When the second parameter is the maximum number of the encoded 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. For example, assuming that the value of the second parameter is 10, the first communication device may determine that the value of N is 8, and at this time, for the first data block, the first communication device may generate 8 encoded sub-blocks, that is, the first data block corresponds to 8 encoded sub-blocks.

3) Third parameter

The third parameter may be used to determine a distribution of degrees of freedom.

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

4) Pseudo random code seed

The pseudorandom code seed may be used to determine column vector information corresponding to the encoded sub-blocks.

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

In a first implementation, the column vector information may include degrees of freedom of the column vector and a number of an element having a value of 1 in the column vector.

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

As can be seen from the above, the first and second pseudorandom code seeds function differently, and thus, the first and second pseudorandom code seeds may be considered as different types of pseudorandom code seeds.

In particular, the expressions of different types of pseudo-random code seeds may be different, such as: the first pseudorandom code seed may be represented as Arabic numerals and the second pseudorandom code seed may be represented as English letters. In this way, the communication device can distinguish between different types of pseudo random code seeds. Of course, the above-mentioned modes are only examples, and in practical applications, different types of pseudo random code seeds may also be distinguished by other modes, which is not limited in the embodiment of the present invention.

In specific implementation, the first pseudo-random code seed may generate N values, each value representing a value of a degree of freedom of a column vector; the second pseudorandom code seed may generate N sets of values, each set of values including V values, a value of V being equal to a number of elements of a value 1 in the column vector, each value of V representing a number of elements of a value 1 in the column vector.

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

Then the first communications device may determine, based on said first pseudo random code seed, that N takes a value of 6, the coding matrix comprises 6 column vectors, and the degree of freedom of the first column vector is 2, the degree of freedom of the second column vector 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 values of a first element and a second element in the first column vector are 1, and values of the remaining elements are 0; the values of the first element, the third element and the fifth element in the first column vector are 1, and the values of the other elements are 0; all elements in the third column vector and the fourth column vector take values of 1; the value of the third element in the fifth column vector is 1, and the values of the other elements are 0; the values of the fourth element and the fifth element in the sixth column vector are 1, and the values of the other elements are 0.

Based on the above, the first communication device may generate the coding matrix M:

assuming that the first data block is 11001, the first communication device may generate P ═ 11001, based on the obtained value of 5 of K.

Thus, the first communication device generates 6 encoded 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 all of the N values obey the distribution of the degree of freedom d.

Exemplarily, assuming that d obeys positive-probability distribution, the value can be obtained as 1 according to the distribution probability of d; 3; 5; 5; 2, etc.

If the first pseudorandom code seed is 2, the value sequence obtained based on the first pseudorandom code seed is 2; 3; 5; 5; 1.

if the first pseudorandom code seed is 3, the value sequence obtained based on the first pseudorandom code seed is 2; 3; 1; 2; 1.

as can be seen, the first pseudorandom code seed may be used to determine the corresponding degree of freedom of the encoded sub-block.

Similarly, the N sets of values generated by the second pseudorandom code seed may be different for different values.

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

In a second implementation, the pseudorandom code seed may be used to generate N column vectors. Thus, the first communication device may generate the encoding matrix M based on the generated N column vectors; in addition, the first communication device may determine the value of K based on the number of elements included in any one of the generated N column vectors, generating the first data block P. Thereafter, N encoded sub-blocks of the first data block are generated.

It can be seen that in the case where the network coding parameters include the pseudo random code seed, the second communication device may autonomously determine a column vector corresponding to the coded sub-block based on the pseudo random code seed, such that signaling overhead between the first communication device and the second communication device may be reduced as compared to the second communication device determining a column vector corresponding to the coded sub-block based on the indication of the first communication device.

4) Numbering

The number is the number of the network coding parameter combination and can be used for indicating the network coding parameter combination. The network coding parameter combinations may include at least two of: 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 L network coding parameter combinations of the P network coding parameter combinations based on the L numbers.

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

Then, in the case where L is 1, the first communication device may determine K, N, c and the value of δ.

When L is greater than 1, the first communication device may select a target number from the master and slave L numbers, and further determine K, N, c and δ values according to a target coding parameter combination corresponding to the target number.

As can be seen from the above, the value of K can be obtained by any of the following methods:

and obtaining the value of K according to the first parameter in a first obtaining mode.

And in the second acquisition mode, the value of K is acquired according to the serial number of the network coding parameter combination, and the network coding parameter combination comprises the first parameter.

The value of N can be obtained by any one of the following methods:

and acquiring the value of N according to the second parameter.

And the acquisition mode is four, the value of N is acquired according to the serial number of the network coding parameter combination, and the network coding parameter combination comprises a second parameter.

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

In this embodiment, the purpose of the first communication device acquiring the network coding parameter is to: and generating a first data block P and a coding matrix M, and further generating N coding sub-blocks of the first data block according to the generated first data block P and the coding matrix M.

For the first data block P, after the first communication device obtains the value of K, the first data block P may be generated.

For the encoding matrix M, it may be generated from K, N, c and δ.

In summary, the network coding parameters in any of the following expressions may enable the first communication device to generate the first data block P and generate the coding matrix M, and further generate N coding sub-blocks of the first data block according to the generated first data block P and the coding matrix M.

In expression one, the network coding parameters include L first parameters, L second parameters, and a third parameter.

For the network coding parameter expressed in the first expression, in the case that L is greater than 1, the first communication device may select one first parameter from the L first parameters, and then determine the value of K based on the first parameter; one second parameter may be selected from 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 are in one-to-one correspondence. In this way, the first communication device can select only the first parameter or the second parameter, and thereafter, can determine the other one of the first parameter and the second parameter based on the above correspondence relationship, whereby the selection operation of the first communication device can be simplified.

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

Further, in case the number of the third parameters is Q, the Q third parameters satisfy at least one of:

the Q third parameters correspond to the L first parameters;

the Q third parameters correspond to the L second parameters.

Under the condition that the Q third parameters correspond to the L first parameters, if the value of Q is smaller than the value of L, one of the L first parameters may correspond to one of the Q third parameters, or may correspond to two or more of the Q third parameters; if the value of Q is equal to the value of L, one parameter in the L first parameters corresponds to one parameter in the Q third parameters. In this case, the first communication device may determine the third parameter based on the determined first parameter.

Similarly, in a case where the Q third parameters correspond to the L second parameters, if the value of Q is smaller than the value of L, one of the L second parameters may correspond to one of the Q third parameters, or may correspond to two or more of the Q third parameters; if the value of Q is equal to the value of L, one of the L second parameters corresponds to one of the Q third parameters. In this case, the first communication device may determine the third parameter based on the determined second parameter.

In expression two, the network coding parameter includes L numbers.

For the network coding parameter of manifestation two, in case the network coding parameter combination includes the first parameter, the second parameter and the third parameter, the network coding parameter may include only L numbers.

In case the network coding parameter combination comprises the first parameter and the third parameter, the network coding parameter may further comprise L second parameters.

In case the network coding parameter combination comprises the first parameter and the second parameter, the network coding parameter may further comprise a third parameter.

In case the network coding parameter combination comprises the second parameter and the third parameter, the network coding parameter may further comprise L first parameters.

For the network coding parameter of expression two, in case 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 parameter.

It should be noted that, in practical application, optionally, the value of N determined by the first communication device may be greater than the value of K, so as to improve reliability of data block transmission. For example, assuming that the network coding parameters include 1 first parameter and 1 second parameter, the first parameter is the maximum divisible number of the first data block, the second parameter is the maximum number of coding sub-blocks corresponding to the first data block, and 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 network coding parameters in the above expression are only examples, and any network coding parameters that enable the first communication device to generate the first data block P and generate the coding matrix M, and further generate the N coding sub-blocks of the first data block according to the generated first data block P and the generated coding matrix M may fall within the protection scope of the embodiment of the present invention.

In a 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 the degrees of freedom d, K, and N, to generate the coding matrix M, it is necessary to determine the degrees of freedom corresponding to N column vectors in the coding matrix, respectively, and the number of an element whose value is 1 in each of the N column vectors.

In the first embodiment, the first communication device may autonomously determine, according to the distribution of the degrees of freedom d, degrees of freedom corresponding to N column vectors in the coding matrix, respectively, and numbers of elements having a value of 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 may generate degrees of freedom of N column vectors based on the pseudo random code seed, and the number of elements of the N column vectors, each of which takes a value of 1.

It is to 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 numbers of the elements having a value of 1 in each of the N column vectors, the network coding parameters of the first expression and the second expression may further include pseudo random code seeds.

It should be noted that, with the first embodiment, since the degrees of freedom corresponding to the N column vectors in the coding matrix respectively and the numbers of the elements whose values are 1 in each of the N column vectors are autonomously determined by the first communication device, in order to enable the second communication device to successfully decode, the first communication device should instruct the second communication device to determine the degrees of freedom corresponding to the N column vectors in the coding matrix respectively and the numbers of the elements whose values are 1 in each of the N column vectors.

For the second embodiment, because the degrees of freedom corresponding to the N column vectors in the coding matrix respectively and the numbers of the elements whose values are 1 in each column vector in the N column vectors are determined by the pseudo random code seeds, the second communication device can determine the degrees of freedom corresponding to the N column vectors in the coding matrix respectively and the numbers of the elements whose values are 1 in each column vector in the N column vectors by acquiring the pseudo random code seeds, and does not need the first communication device to indicate, thereby reducing the signaling overhead between the first communication device and the second communication device.

The header of the encoded subblock is explained below.

Optionally, in a case that L is 1, the header of a first encoded sub-block of the N encoded sub-blocks includes a first aggregation field, and the first aggregation field includes at least one of:

a first field indicating a number of divided copies of the first data block;

a second field indicating a number of the first data block;

a third field indicating a number of the first encoded sub-block;

a fourth field for indicating column vector information corresponding to the first encoded sub-block;

a fifth field for indicating a data length of the first encoded sub-block.

Optionally, in a case that L is greater than 1, the header of a first encoded subblock of the N encoded subblocks includes a second aggregation field, and the second aggregation field includes at least one of:

a first field indicating a number of divided copies of the first data block;

a sixth field indicating a fourth parameter having a correspondence with the number of divided pieces of the first data block;

a seventh field for indicating a target number of the L numbers;

a second field indicating a number of the first data block;

a third field indicating a number of the first encoded sub-block;

a fifth field for indicating a data length of the first encoded sub-block.

For convenience of understanding, the above domains are explained below.

1) First domain

The first field is used for indicating the number of the division copies of the first data block, namely 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 encoded sub-block.

2) Second domain

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

3) Third domain

The third field is used to indicate the number of the first encoded sub-block. In practical applications, the value of N is generally greater than 1, and it can be known from the foregoing that the column vectors in the coding matrices corresponding to different coding sub-blocks are different. Thus, to facilitate the second communications device to accurately determine the column vector corresponding to each encoded sub-block, the first communications device may carry a third field in the header of each encoded sub-block, indicating the number of that encoded sub-block.

4) Fourth field

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

5) The fifth domain

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

6) Domain six

The sixth field is configured to indicate a fourth parameter, and the fourth parameter has a correspondence with the number of divided copies of the first data block. In practical application, the protocol may agree on a corresponding relationship 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; and if the value of the fourth parameter is 2, the value of K corresponding to the fourth parameter is 5. In this way, the second communication device may determine the value of K based on the fourth parameter indicated by the sixth field and the correspondence.

7) Seventh Domain

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

As can be seen from the foregoing, the first field, the sixth field, and the seventh field may all be used to determine the value of K, and thus, the first communication device may explicitly indicate the value of K by carrying the first field, the sixth field, or the seventh field in the header of the encoded sub-block.

In other embodiments, the first communication device may implicitly indicate the value of K. Optionally, in a case that L is greater than 1, a size of a first encoded sub-block of the N encoded sub-blocks corresponds to any one of:

the number of partitions of the first data block;

and the number of the network coding parameter combination corresponding to the division number of the first data block.

In this alternative embodiment, K has different values and the size of the encoded sub-blocks is different. Specifically, the value of K may be negatively related to the size of the encoded sub-block, that is, the smaller the value of K is, the larger the size of the encoded sub-block is, and the smaller the inverse value is. In practical applications, the size of the 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 encoded sub-block corresponding to the same data block.

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

In this embodiment, when the protocol definition or the network (pre) configures a plurality of optional network coding layer parameters, such as L first parameters, a header (header) of the network coding layer or a sub-header (sub-header) of the network coding sub-layer may explicitly indicate the parameters used, or the network coding layer parameters may be implicitly indicated.

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

In addition, the headers of different encoded sub-blocks in the N encoded sub-blocks may be the same or different. For example, since one data block corresponds to one K value, the first field indication K value may be carried by one encoded sub-block corresponding to the data block, and the other encoded sub-blocks corresponding to the data block may not carry the first field.

In practical applications, as can be seen from the foregoing, if the second communication device determines to acquire the column vector corresponding to the received encoded sub-block through the first implementation manner, the header of the encoded sub-block may include the fourth field. If the second communication device determines to acquire the column vector corresponding to the received encoded sub-block through the second embodiment, the header of the encoded sub-block may not include the fourth field, so that the signaling overhead between the first communication device and the second communication device may be reduced.

As can be seen from the foregoing, the first communication device may network encode the data block through the target layer. In practical applications, the target layer may be:

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

a second layer in a RAN protocol stack;

the first layer may be regarded as an existing layer in a RAN Protocol stack, such as a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Backhaul Adaptive Protocol (BAP) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer; the second layer may be regarded as a newly added layer in the RAN protocol stack.

Hereinafter, the case where the target layer is the first layer and the target layer is the second layer will be described.

In case one, the target layer is the first layer.

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

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

Since the target layer is an existing layer, optionally, the header of the first encoded sub-block may further include a third aggregation field, where the third aggregation field is generated by a sub-layer other than the network encoded sub-layer in the target layer.

In this case, the header of the encoded subblock includes a first target set field, which may be considered as a first subheader of the encoded subblock, and a third set field, which may be considered as a second subheader of the encoded subblock. The third aggregation field is generated by the sub-layers of the first layer except the network coding sub-layer, and the second sub-header may be regarded as the original header of the first layer.

Further, the third set field is located before the first target set field, or the third set field is located after the first target set field.

And under the condition that the third aggregation domain is positioned in front of the first target aggregation domain, the first layer firstly carries out network coding processing to generate the first target aggregation domain, and then carries out the existing processing of the first layer to generate the third aggregation domain.

And under the condition that the third set domain is positioned behind the first target set domain, the first layer firstly carries out the existing processing of the first layer to generate the third set domain, and then carries out the network coding processing to generate the first target set domain.

In case two, the target layer is the second layer.

In case two, the target layer is an independent layer, and thus, the header of the encoded subblock may include only the first target set field.

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

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

the network coding layer is arranged between a packet data convergence protocol PDCP layer and a radio link control RLC layer;

the network coding layer is arranged between the PDCP layer and the feedback adaptive protocol BAP layer.

Referring to fig. 2, fig. 2 is a second flowchart of a data processing method according to an embodiment of the present invention. The data processing method shown in fig. 2 may be applied to the second communication device.

Step 202, generating a first matrix, wherein the first matrix comprises the M column vectors.

And 203, recovering the first data block according to the first matrix and the M coding sub-blocks when the first matrix is a row full rank matrix.

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

In the case that the number of received encoded sub-blocks of the first data block may be greater than M, the second communication device may select M encoded sub-blocks from the received encoded sub-blocks, determine whether a matrix generated by M column vectors corresponding to the M encoded sub-blocks is a row full rank matrix, and find those encoded sub-blocks that result in a row full rank of the first matrix.

The recovering the first data block according to the first matrix and the M encoded sub-blocks may specifically include: and obtaining data subblocks corresponding to the first data block according to the first matrix and the M coding subblocks, and then combining the obtained array subblocks in sequence to obtain the first data block.

It should be noted that, in practical applications, the second communication device may perform the above steps through the target layer. The target layer may refer to the foregoing description, and details are not repeated here.

Optionally, the obtaining M column vectors corresponding to the M coding sub-blocks includes:

and the fourth field in the header of each of the M encoded sub-blocks is used for indicating the column vector information corresponding to the encoded sub-block.

Optionally, when L is greater than 1, the L second parameters correspond to the L first parameters.

Optionally, 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;

Optionally, the header of the second encoded sub-block of the M encoded sub-blocks further includes a fourth aggregation field, and the fourth aggregation field includes at least one of:

a first field indicating a number of divided copies of the first data block;

Optionally, the header of the second encoded sub-block of the M encoded sub-blocks further includes a fifth aggregation field, and the fifth aggregation field includes at least one of:

a second field indicating a number of the first data block;

the second target aggregate domain is the fourth aggregate domain or the fifth aggregate domain.

Optionally, the sixth set domain is located before the second target set domain, or the third set domain is located after the second target set domain.

In the data processing method of this embodiment, the second communication device may decode and acquire the first data block based on the received encoded sub-block. Therefore, the embodiment of the invention realizes the transmission of the first data block from the first communication device to the second communication device by adopting a network coding mode, thereby reducing the redundancy of data transmission and further improving the frequency spectrum utilization rate under the condition of ensuring the reliability of data transmission.

It should be noted that the present embodiment is taken as an embodiment of the second communication device corresponding to the method embodiment corresponding to fig. 1, so that reference may be made to relevant descriptions in the method embodiment corresponding to fig. 1, and the same beneficial effects may be achieved. To avoid repetition of the description, the description is omitted.

Referring to fig. 3, fig. 3 is a flowchart of a configuration method according to an embodiment of the present invention. The configuration method shown in fig. 3 may be applied to the third communication device.

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 the configuration method of this embodiment, the third communication device may configure the network coding parameter by sending the configuration information, so that the first communication device and the second communication device may perform network coding and decoding on the data block based on the network coding parameter, and further, the redundancy of data transmission may be reduced under the condition that the reliability of data transmission is ensured, and further, the spectrum utilization rate may be improved.

It should be noted that the present embodiment is taken as an embodiment of the third communication device corresponding to the method embodiment corresponding to fig. 1, so that reference may be made to relevant descriptions in the method embodiment corresponding to fig. 1, and the same beneficial effects may be achieved. To avoid repetition of the description, the description is omitted.

It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or separately without conflict between the implementations, and the embodiments of the present invention are not limited in this respect.

For ease of understanding, examples are illustrated below:

network Coding (NWC) may be a completely new protocol layer or an extended sub-layer of a certain layer in an existing protocol stack. The invention designs a protocol design and a related signaling design when a network code is used for RAN data transmission, wherein the protocol design and the related signaling design comprise 'network code parameter configuration' and 'NWC header design', the configuration can be configured according to communication equipment, or can be configured according to MAC (media access control) entry, cell group or LCH/LCG (link control group) of the communication equipment, consistent network codes can be configured, and flexibility of selecting according to situations can be provided by configuring various network codes.

For brevity of description, in the following detailed description, it is assumed that the network coding is configured by LCH (i.e. per LCH). These solutions can be generalized to network coding configuration according to MAC entry, 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, fig. 4 shows a flow chart of a network control unit configured for network coding by LCH; FIG. 5 is a flow chart of an originating end for network code configuration by LCH; fig. 6 shows a flow chart of the reception of network coding configuration per LCH.

Fig. 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 LCH network coding parameters of the receiving end.

In practical application, the originating LCH network coding parameter and the receiving LCH network coding parameter configured by the network control unit may be the same or different.

Fig. 5 includes the following steps:

step 501, receiving a network coding parameter of an LCH of a communication device.

Step 502, determining the header format of the encoded sub-blocks.

Step 503, according to the network coding parameters of the LCH and the header format of the coding sub-block, performing network coding processing on the data block of the LCH to generate a coding sub-block.

And step 504, transmitting the encoded sub-block generated by the LCH.

Fig. 6 includes the following steps:

step 601, receiving a network coding parameter of an LCH of the communication device.

Step 602, determining the header format of the encoded sub-block.

Step 603, receiving the encoded sub-block of the LCH.

And step 604, decoding the received encoded sub-block of the LCH according to the network encoding parameters of the LCH and the header format of the encoded sub-block, and recovering the data block.

It should be noted that, in some embodiments, the receiving end may directly decode the received encoded sub-block of the LCH according to the header format of the encoded sub-block, and recover 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 encoded sub-block may be predetermined by a protocol, and in particular, the header format of the encoded sub-block may include at least one of the first field to the seventh field.

The NWC layer is newly added between any two layers in the existing RAN protocol stack.

When the configuration of the network coding parameters is in a one-to-one correspondence with the LCH.

The configuration of the network coding contains one or more of the following parameters:

protocol definition or network (pre) configuration of a fixed number K (or a maximum divisible number Kmax) of equally divided original data blocks;

the protocol definition or network (pre) configures the code number N (or the maximum code sub-block number Nmax) generated by the code of an original data block;

the "coding matrix parameters" are used to generate a coding matrix, and include at least one of the following parameters: relevant parameters of the degree of freedom d are defined by a protocol or configured by a network (pre), and the distribution of d is generated locally according to the relevant parameters;

protocol definition or network (pre) configuration pseudo-random code seeds (both transmitting and receiving ends are equipped) for generating the number of the original data subblock required to be used when the coding subblock is coded;

defining a protocol or configuring a network coding parameter combination number by a network (pre), wherein the parameter combination comprises a K value, an N value and related parameters generated by a coding matrix; different "parameter combination numbers" correspond to different network coding parameter configurations.

The header of the network coding layer may include at least one of the following fields:

the number K of the original data blocks which are actually divided into equal parts;

the number (index) of the network coding layer original data block (NWC SDU);

the number of the encoded sub-block (encoded packet) generated after encoding;

the transmitting end carries the number of the original data subblock used when the coding subblock is coded in the NWC header of each coding subblock;

the data length of the sub-block is encoded.

When the configuration of the network coding parameters is in a many-to-one relationship with the LCH/CG.

protocol definition or network (pre) configuration L (L > ═ 1) values of equal parts of the original data: k1, K2, …, KL;

protocol definition or network (pre) configuration and K1, K2, …, KL corresponding to the number of codes generated by encoding an original data block N1, N2, …, NL (or the maximum number of encoded sub-blocks Nmax);

protocol definition or network (pre) configuration of 'encoding matrix parameters', which are related parameters for generating a degree of freedom d, locally generate the distribution of d according to the related parameters, and for different values of K and N, the same 'encoding matrix parameters' can be configured, or different 'encoding matrix parameters' can be configured for different values of K (or combinations of K values) or N (or combinations of N values), and if the latter, the 'encoding matrix parameters' used can be implicitly indicated by the value of K or the value of N;

protocol definition or network (pre) configuration of a plurality of 'network coding parameter combination numbers', wherein 'parameter combination' comprises a K value, an N value and 'coding matrix parameters'; different "parameter combination numbers" correspond to different network coding parameter configurations.

The parameters used may be explicitly indicated in a header (header) of the network coding layer when a protocol definition or the network (pre) configures a number of optional parameters. In this regard, the header (header) of the network coding layer may contain one or more of the following fields:

the number of parts Kl taken by equal division of the original data block (assuming that a total of L (L > -1) options, the ith part is selected from K1, K2 and KL; one maximum division part Kmax is selected from L maximum division parts Kmax, and then the specific part Kl is determined);

"network coding matrix numbering": the Index is used for indicating the actually selected K value from the L alternative values (one network coding matrix Index in the header is used to indicate the selected K value, if the method indicated by the Index is used, protocol definition is needed, or the network configures the relationship between the value of K and the Index, for example, there is a list of K values, i 1 corresponds to K4, i 2 corresponds to K5);

"network coding parameter combination number": a value indicating the number of copies K actually taken for the original data aliquot splitting;

number (index) of NWC original Data block (Service Data Unit, SDU);

the number of the encoded sub-block (encoded packet) generated after encoding;

the transmitting end carries the number of the original data subblock corresponding to each coding subblock in the NWC header of each coding subblock;

the data length of the sub-block is encoded.

When a protocol defines or the network (pre) configures a number of optional network coding layer parameters, the network coding layer parameters may be implicitly indicated, in which case no header of the network coding layer is required to indicate the selected parameters with additional information.

As an example of an implicit indication, the size of the received coding sub-block may be used to indicate the network coding layer parameters used (assuming that different network coding layer parameters correspond to different coding block sizes).

The NWC layer may be an extension sublayer (sublayer) of any one of PDCP, BAP, or RLC in an existing RAN protocol stack.

At this time, the header of the NWC may be regarded as an extension (extension) of the header of the PDCP, BAP, or RLC.

When the NWC is an extended sublayer of a certain layer, the required design and configuration is consistent with one.
