Zusammenfassung:	This application provides a data transmission method and an apparatus. In the provided method, network coding-based data transmission is introduced, and adaptive adjustment is performed on HARQ retransmission and network coding-based transmission based on a data reception status or channel quality According to the method, when the data reception status is poor or the channel quality is poor, a combination gain of HARQ retransmission can be used to increase a probability of successful data reception, and when the data reception status is good or the channel quality is good, network coding-based transmission can be used to reduce excessive resource occupation in a HARQ retransmission process. This increases spectral efficiency in a data transmission process.
