Abstract
A data retransmission method, apparatus, and system can improve a success ratio of data packet retransmission. A data retransmission method includes: after a source node continuously transmits at least two data packets to a destination node according to a go-back-N automatic repeat request, monitoring and decoding, by a relay node, the at least two data packets; storing a copy of a successfully decoded data packet; monitoring a response message to each data packet, where the response message is returned by the destination node to the source node; and sending a copy of a data packet that corresponds to a reception negative acknowledgment message to the destination node, when the monitored response message is the reception negative acknowledgment message.
