Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
Example (b):
the present embodiment provides a data encoding method, as shown in fig. 1, including:
s101, determining a target redundancy version of data to be transmitted;
s102, determining the initial position of target data according to the target redundancy version;
s103, determining a target sub-matrix from the LDPC coding matrix according to the initial position of the target data and the data length of the target data;
s104, encoding data to be transmitted by adopting a target sub-matrix to obtain target data;
in this embodiment, the encoded data to be transmitted is defined with at least two redundancy versions, where the redundancy versions correspond to different initial positions of the encoded data, and it should be noted that the encoded data is obtained by completely encoding the data to be transmitted by using an encoding matrix. For example, in this embodiment, an IR-HARQ technique or the like is correspondingly used when transmitting data, and in the process of information transmission, the transmitting end first sends data of one redundancy version, and if the receiving end fails to decode successfully, the transmitting end may send data of another redundancy version.
The data to be transmitted in the present embodiment includes code blocks generated from transport blocks. For example, the code block may be obtained by cutting a transport block, in some examples, a transport block larger than a predetermined length is cut into a code block of a predetermined length, in other examples, the transport block may be regarded as a code block if the length of the transport block is smaller than the predetermined length. In practical applications, each code block may further be added with a Cyclic Redundancy Check (CRC) code.
In the data coding method, the target redundancy version needing to be coded is determined, the initial position of the target data is determined, and the coded data are not calculated in the process. That is to say, this embodiment does not perform complete encoding on data to be transmitted, and since each transmission only involves one of the redundancy versions, the encoded data is not completely transmitted at one time. Of course, the target data can be obtained only after the data to be encoded is encoded, and although the data to be encoded is not encoded in advance in the embodiment, the target redundancy version can reflect the start position of the target data. In addition, according to the actual transmission requirement, the data length of each transmission can be determined before encoding.
It will be appreciated that although the complete encoded data is not determined, knowing the starting position of the target data and its data length is sufficient to determine the range of positions of the target data within the entire encoded data. In the encoding process of this embodiment, the determined encoding matrix can be used to encode complete encoded data depending on the encoding matrix, and based on the calculation rule of the matrix, when partial content of the matrix is used, partial data corresponding to the partial matrix can also be calculated.
The target sub-matrix is a part of the encoding matrix, and specifically, the target sub-matrix is a part of the encoding matrix corresponding to the target data, and the data to be encoded and the target sub-matrix are operated, and the obtained result is the target data.
It can be seen that, in the data encoding method of this embodiment, in the process of encoding data, only a part of the encoding matrix is used for encoding operation according to the target redundancy version. Compared with the method of calculating complete coded data first and then intercepting and sending the part corresponding to the redundancy version in the related technology, the method of the embodiment only relates to the operation of a partial matrix in a single operation, the single operation amount is less, the operation speed is higher, and especially when the first redundancy version is sent, the transmission delay is low; in some implementations, for example, in a scenario where the first decoding success rate is high, the overall computation amount and delay can be significantly reduced.
The target redundancy version in this embodiment may be a redundancy version that needs to be currently transmitted, that is, this embodiment may perform partial encoding on the part of data of the redundancy version that needs to be currently transmitted. The target redundancy version can also be a redundancy version which needs to be transmitted next time, and the required data is obtained by encoding only, and the data which does not need to be transmitted does not need to be operated.
In some embodiments, the encoding matrix includes, but is not limited to, an LDPC encoding matrix and other encoding matrices capable of encoding to obtain redundant check information, as shown in fig. 2, the LDPC encoding matrix includes a core check matrix a and an extended check matrix B; the encoded data includes a first sub-code block corresponding to the core check matrix a and a second sub-code block corresponding to the extended check matrix B. The core check matrix A completes basic LDPC coding, and the extension check matrix B is used for generating redundant check information to complete IR-HARQ and adapt to different code rate requirements. The LDPC coding matrix in this embodiment may have been adapted to the code rate requirement, that is, the extended check matrix B is designed according to the required code rate requirement, and the data coding method of this embodiment can be practically applied to the communication process with any code rate. Illustratively, the extended check matrix B includes, but is not limited to, at least one of a row quasi-orthogonal matrix, a row orthogonal matrix, and a non-row orthogonal matrix; the specific design manner of the extended check matrix B is not limited in this embodiment, and other matrices or combinations of matrices may also be used as the extended check matrix B. For ease of understanding, referring to fig. 3, in the IR-HARQ protocol, the encoded data is defined as a circular structure, and in the related art, the encoded data may be put into a circular buffer for use after being obtained, for example, the encoded data of fig. 3 is shown in a clockwise direction in a circular loop, and the tail of the second sub-code block 20 is connected to the head of the first sub-code block 10. In this embodiment, the encoded data in the example is not actually obtained, but the same rule is still applied to the redundancy version and the corresponding actual data.
Illustratively, the redundancy versions of the data to be transmitted include at least two, each redundancy version corresponds to a different starting position, and at least one of the redundancy versions has an independent decoding capability. The redundancy version data with independent decoding capability at least comprises a complete first sub-code block and a part of a second sub-code block, and decoding can be attempted through information contained in the data. In practical applications, the sequential first-order redundancy versions have independent decoding capability.
In some embodiments, the redundancy versions include a first redundancy version, the start position of the first redundancy version corresponds to the head of the first sub-code block, the first redundancy version corresponds to the complete first sub-code block and a part of the second sub-code block, and determining a target sub-matrix from the LDPC coding matrix according to the start position of the target data and the data length of the target data includes:
determining that the target sub-matrix comprises the complete core check matrix and the region of the extended check matrix corresponding to the part of the second sub-code block corresponding to the first redundancy version.
In some embodiments, the redundancy versions include a second redundancy version, the second redundancy version corresponds to a portion of the second sub-code block, and a range to which the second redundancy version corresponds does not overlap with a range to which the first redundancy version corresponds;
determining a target sub-matrix from the LDPC coding matrix according to the starting position of the target data and the data length of the target data comprises:
it is determined that the target sub-matrix comprises a region of the extended check matrix corresponding to the portion of the second sub-code block corresponding to the second redundancy version.
In some embodiments, the redundancy versions include a third redundancy version corresponding to a starting position within the second sub-code block, the third redundancy version corresponding to a portion of the first sub-code block and a portion of the second sub-code block;
determining a target sub-matrix from the LDPC coding matrix according to the starting position of the target data and the data length of the target data comprises:
and determining that the target sub-matrix comprises the area of the core check matrix corresponding to the part of the first sub-code block corresponding to the third redundancy version and the area of the extended check matrix corresponding to the part of the second sub-code block corresponding to the third redundancy version.
In some embodiments, the redundancy versions include a fourth redundancy version having a starting position within the first sub-code block and corresponding to a portion of the first sub-code block and a portion of the second sub-code block.
For better understanding, the data encoding method of the present embodiment is described below with reference to an example of a specific communication procedure.
In this example, four redundancy versions RV0, RV1, RV2, and RV3 are defined as the encoded data of the data to be transmitted, the starting position of each redundancy version is shown in fig. 3, the starting position of the redundancy version RV0 is at the head of the first sub-code block 10, the starting position of the redundancy version RV1 is at a certain position in the first sub-code block 10, the starting positions of the redundancy version RV2 and the redundancy version RV3 are at certain positions in the second sub-code block 20, and the starting positions of the redundancy versions RV0, RV1, RV2, and RV3 are distributed in the clockwise direction of the drawing and are different from each other. On the premise of meeting the specification requirement, the data length corresponding to each redundancy version is determined according to the actual situation, and this example is not limited.
Wherein (the data of) the redundancy version RV0 covers the complete first sub-code block 10 and part of the second sub-code block 20, and thus the redundancy version RV0 has self-decoding capability; when the first transmission is carried out, the redundancy version RV0 is transmitted firstly. As shown in fig. 4, in this embodiment, a matrix within the range of X1 in the LDPC coding matrix is determined as a target sub-matrix according to the start position and the length of the redundancy version RV0. And coding the code block needing to be transmitted at this time by adopting the target sub-matrix, wherein the target sub-matrix can be independently cut out, or the coding is finished when the code block reaches the boundary of the target sub-matrix. The obtained target data is the part of the encoded data corresponding to the redundancy version RV0, and after the target data is obtained, the target data can be sent to a receiving end, and the receiving end tries to decode after receiving the target data.
If the information that the receiving end has not successfully decoded is received, the next redundancy version needs to be transmitted at this time, and in this embodiment, the transmission order of the redundancy versions is RV0, RV2, RV3, and RV1 in sequence, so that the redundancy version RV2 needs to be transmitted at this time. In some implementation processes, the receiving end may also directly request the transmitting end for data to be transmitted again without feeding back whether the decoding is successful, and at this time, the next redundancy version also needs to be encoded and transmitted.
The redundancy version RV2 is encoded, in this example, the redundancy version RV2 and the redundancy version RV0 do not overlap with each other, and in some examples, the redundancy version RV2 may complement the redundancy version RV0 to form complete encoded data. As shown in fig. 5, a matrix within the range of X2 in the LDPC coding matrix is determined as a target sub-matrix according to the starting position and the length of the redundancy version RV2, and a part of the extended check matrix is included within the range of X2 in the LDPC coding matrix.
If information that the receiving end has not successfully decoded is received, the redundancy version RV3 is encoded in sequence, and the redundancy version RV3 includes a rear portion of the second sub-code block 20 and a front portion of the first sub-code block 10. As shown in fig. 6, a matrix within the range of X3 in the LDPC coding matrix is determined as a target sub-matrix according to the starting position and the length of the redundancy version RV3, and a part of the core check matrix and a part of the extended check matrix are included in the range of X3 in the LDPC coding matrix.
Similarly, if the information that the receiving end has not successfully decoded is still received, the redundancy version RV4 is encoded in sequence, and the redundancy version RV4 includes a rear portion of the first sub-code block 10 and a front portion of the second sub-code block 20. As shown in fig. 7, a matrix within the range of X4 in the LDPC coding matrix is determined as a target sub-matrix according to the starting position and the length of the redundancy version RV4, and a part of the core check matrix and a part of the extended check matrix are included in the range of X4 in the LDPC coding matrix. It can be understood that, due to the difference between the starting positions of redundancy version RV4 and redundancy version RV3, although both partially cover the core check matrix and the extended check matrix, the range of X4 in the LDPC coding matrix is not equal to the range of X3 in the LDPC coding matrix.
In practical applications, the division of the redundancy version of the encoded data may also take other forms, and the embodiment is not limited to this. The redundant versions divided by other forms can also adopt the data coding method of the embodiment, so that the effects of lower time delay of single coding and lower computation amount are achieved.
In the above example, after receiving the message to be encoded, the data to be encoded is encoded to obtain the target data.
As yet another example, the target data may be obtained in advance before the message to be encoded is received, i.e., the target redundancy version may not be the redundancy version that is currently being transmitted immediately.
Illustratively, the redundancy version definition of this example is the same as the previous example. When transmitting for the first time, the redundancy version RV0 is still transmitted first. When the redundancy version RV0 is sent, the data encoding method in this embodiment is still used, and only the portion of the matrix corresponding to the redundancy version RV0 is used to encode the data to be encoded, the obtained target data is the portion of the data corresponding to the redundancy version RV0 in the encoded data, after the target data is obtained, the target data may be sent to a receiving end, and the receiving end tries to decode after receiving the target data.
In this example, after the coding of the redundancy version RV0 is completed, the redundancy version RV2 that needs to be sent next time is coded immediately, that is, the redundancy version RV2 is used as a target redundancy version, and a matrix within the range of X2 in the LDPC coding matrix is determined as a target sub-matrix according to the start position and the length of the redundancy version RV2. The target data obtained by encoding according to the redundancy version RV2 can be stored in a cache in advance, and when information that the receiving end does not successfully decode is received, the target data obtained by encoding according to the redundancy version RV2 can be immediately sent to the receiving end. After the target data obtained by encoding the redundancy version RV2 is sent, the target data of the redundancy version RV3 that needs to be sent next time may be encoded in advance by using the foregoing method. If the receiving end decodes successfully according to the target data, the target data stored in the cache can be cleared.
The embodiment encodes the redundancy version which is possibly required to be transmitted in advance, only a part of encoding matrixes are needed to be adopted according to data covered by the redundancy version in the encoding process, the single encoding computation and the time delay are low, and the overall communication time delay is lower particularly in a scene with a low decoding success rate.
