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.
