Abstract: This application discloses a data transmission method, a sending device, a receiving device, and a communications system. The sending device is configured to send a first transport block. The sending device obtains a coded bit segment from a first encoded code block. The first encoded code block is obtained after LDPC encoding is performed on a first code block in the first transport block based on a processing capability of the receiving device. The sending device sends the coded bit segment to the receiving device. Because the processing capability of the receiving device is considered, storage overheads of the sending device or the receiving device can be reduced, encoding or decoding complexity can be reduced, and a decoding success rate can be improved.

Abstract: The present disclosure relates to methods and apparatuses for generating a low-density parity-check code basis matrix. One example method includes obtaining a low-density parity-check code mother matrix, and generating a 1st matrix to a qth matrix one by one, where q is a preset positive integer. A Pth matrix in the 1st matrix to the qth matrix is generated in the following manner: selecting a to-be-replaced matrix element in a (P−1)th matrix, where the to-be-replaced matrix element is a matrix element having a value that is not −1 in the (P−1)th matrix, determining a Pth shift factor corresponding to the to-be-replaced matrix element, and replacing the to-be-replaced matrix element in the (P−1)th matrix with the Pth shift factor to obtain the Pth matrix whose cycle length property is better than a cycle length property of the (P−1)th matrix.
