Abstract: The method in embodiments of this application includes: A first communication apparatus obtains a first transport block. The first communication apparatus converts the first transport block into S information segments. The first communication apparatus performs pre-processing on the S information segments based on X processing modes, to obtain G information groups, where each of the G information groups corresponds to one of the X processing modes, G is an integer greater than or equal to 1. The first communication apparatus determines C to-be-encoded code blocks based on the G information groups, and a sum of sizes of the C to-be-encoded code blocks is less than a size of the first transport block. The first communication apparatus performs channel coding on the C to-be-encoded code blocks, to obtain an encoded code block. The first communication apparatus outputs the encoded code block.

Abstract: This application provides an LDPC code encoding method and a communication apparatus, to meet a requirement of increasing redundant bits through retransmission in an IR-HARQ mechanism, so as to decrease a channel coding rate, and improve decoding performance of an LDPC code. In the method, a check matrix of the LDPC code is used as a basic matrix, and the basic matrix is extended to obtain a mother matrix compatible with a plurality of code rates. During LDPC encoding, a transmit device reads, from the mother matrix, a check matrix corresponding to a required code rate, and performs LDPC encoding on an information bit sequence based on the read check matrix. LDPC encoding is performed on the information bit sequence by using check matrices of different sizes, to obtain different quantities of redundant bits.
