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.

Abstract: A data transmission method and a network device are provided. The method can include: determining, by a first network device, that a terminal device enters an RRC inactive state; sending, by the first network device, a first message to a second network device, where the first message is used to configure the second network device, so that the second network device transmits data for the terminal device in the RRC inactive state; and receiving, by the first network device, an acknowledgment message the first message and sent by the second network device. The second network device can transmit data of the terminal device to the first network device to enable the first network device to send the data to a core network, without having to establish a path between the second network device and the core network for the second network device to send the data to the core network.
