Abstract
A data transmission method and apparatus, where a transmission end determines a redundancy time according to a delay requirement of a service, where the redundancy time indicates a time used for transmitting redundant data of native data of the service, and the redundancy time is less than or equal to a time indicated by the delay requirement. The transmission end determines a redundancy quantity N. The transmission end determines N redundancy transmission time intervals according to the redundancy time and the redundancy quantity. After the native data of the service is sent, in case of feedback data is not received within an nth redundancy transmission time interval, transmitting the redundant data of the native data for the nth time according to the nth redundancy transmission time interval.
