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: A data transmission method, a terminal, and a network device are provided. In embodiments of the present disclosure, a terminal sends, in a grant-free mode, first data to a network device by using a grant-free resource, and if the terminal needs to switch from the grant-free mode to a grant mode, the terminal sends, in the grant mode, second data to the network device by using a grant resource. When the terminal initially transmits the first data in the grant-free mode, if the terminal needs to switch from the grant-free mode to the grant mode, the terminal may fall back to the grant mode and transmit data in the grant mode.
