Embodiments of this application provide a data processing method and apparatus, and relate to the communication field, to improve spectral efficiency in network coding-based data transmission. The method includes a transmit end device generating a protocol data unit (PDU) based on a reference size and K network coded packets, generating a transport block (TB) based on the PDU, and outputting the TB.

Data processing method and apparatus

Coding method and apparatus provide for coding a to-be-coded data unit to obtain a coded data unit, where a size of the to-be-coded data unit is related to a size of a first data unit. The first data unit is a transport block TB, a protocol data unit PDU, or a service data unit SDU. The first data unit is generated based on the coded data unit.

Coding method and apparatus

This application describes a data transmission method and a communication apparatus. An example data transmission method includes: performing network coding based on a first data segment, to obtain a first network coded data segment; generating first cyclic redundancy check CRC information and a first data unit based on the first network coded data segment, where the first data unit includes a network coding parameter and the first CRC information that correspond to the first network coded data segment, and the first CRC information is for checking the first network coded data segment; and outputting the first data unit. According to of the example method and communication apparatus of this application, a waste of spectrum resources may be avoided, and spectrum efficiency may be improved.
