Abstract
The present invention provides a data transmission method including: sending, by a transmitter, a source data frame to a receiver, and saving the source data frame; sending, by the transmitter, other data frames to the receiver, and saving the other data frames; receiving, by the transmitter, a data retransmission notification which is related to the source data frame and sent by the receiver; and retrieving, by the transmitter, the source data frame and other data frames from a storage space, where the other data frames are sent by the transmitter to the receiver in a time period from sending the source data frame by the transmitter to receiving the data retransmission notification by the transmitter, and retransmitting the source data frame and the other data frames to the receiver.
