Abstract
A data retransmission method and device are provided to resolve a problem of lacking in a retransmission scheme supporting retransmission via different connections in the prior art. In one embodiment of the invention, the method comprises: upon determining that a transmission node corresponding to a terminal satisfies a multi-transmission node retransmission criterion, selecting, by a target protocol layer in a transmitting device and responsible for managing transmission via multiple transmission nodes, and for a retransmission data packet corresponding to the terminal, at least one transmission node; and performing, via the selected transmission node, data packet retransmission. The embodiment is employed to select, upon determining that a transmission node corresponding to a terminal satisfies the multi-transmission node retransmission criterion, and for a retransmission data packet corresponding to the terminal, at least one transmission node, thereby implementing retransmission via different connects, further increasing reliability and throughput of transmission in a system.
