Method for packet retransmission employing feedback information

A method for retransmitting a packet according to feedback information is provided to improve decoding probability in a receiving terminal by changing a retransmission method in a transmitting terminal according to the feedback information from the receiving terminal and transmitting the packet. A transmitting terminal transmits a packet to a receiving terminal(S410). The channel state information and the receiving confirmation information showing the decoding success of the packet are received from the receiving terminal(S420). If the receiving confirmation information shows the decoding failure, the transmitting terminal changes the retransmission method according to the channel state information(S440). The transmitting terminal transmits the retransmission packet about the packet according to the changed retransmission method(S450).
