Abstract: A method is provided that a transmitting end generates a data segment, where the data segment includes header information and data parts of a plurality of CBs that are obtained by dividing a TB, there is a position mapping relationship between the data parts of the plurality of CBs and N sub-PDUs included in a MAC PDU, and the header information of each CB indicates a position mapping relationship between the CB and a sub-PDU corresponding to the CB. The transmitting end sends the TB that carries the data segment. Therefore, at a receiving end, if a CRC error occurs on the TB, the receiving end obtains a position of each CB and performs a CRC decision by using a CB as a granularity, to obtain a correct CB. Thereby performance of a wireless communication system is improved.

Abstract: A data sending solution based on a maximum latency constraint T is provided. A transmitting end sends (T+B) data blocks, where first T data blocks are original data blocks, last B data blocks are B encoded data blocks, and a quantity of encoded data packets in the encoded data block is flexible and controllable. A receiving end only needs to perform joint decoding on a specific quantity of encoded data packets and a correct data packet in an incorrect data block, to recover an incorrect data packet in the incorrect data block. The solution in this application can meet a requirement of a maximum latency T, and can reduce a quantity of encoded data packets. The solution may be applied to an XR service or another service that has a low-latency requirement.
