Abstract: A data processing method and apparatus are disclosed, which may be applied to communication systems such as 5G and 6G. The method includes: obtaining an extended first codebook based on a second codebook by increasing a quantity of codewords or lengths of codewords, and performing first network coding or decoding based on the first codebook. Linear independence between codewords in the extended first codebook may be ensured as much as possible, so as to generate more valid redundant packets or check packets, thereby improving system reliability. Alternatively, flexible block lengths are supported, so as to perform efficient network coding or decoding on more original data packets, thereby improving system spectral efficiency. This application may be applied to an extended reality XR service or another low-delay service.

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: Embodiments of the present application provide a data processing method. In the data processing method, before channel coding, a transmission control device divides a data flow into N sub-data flows, allocates the N sub-data flows to N transmit ends, and notifies the N transmit ends of a same time-frequency resource used for sending the allocated sub-data flows. By applying the technical solution, the N transmit ends can send different sub-data flows of a same data flow to a same receive end on the same time-frequency resource without a large amount of signaling interworking, and a system throughput can be improved without increasing network implementation complexity.
