Title: Method for retransmitting packets according to decoding failures or reliability

Abstract: A method for retransmitting packets in accordance with decoding failure or reliability is disclosed. A method for retransmitting packets from a transmitting side in accordance with information of a receiving side comprises changing an order of packet symbols mapped with subcarriers, if retransmission information representing decoding success or reliability for a specific codeword is received from the receiving side mapping the packet symbols with the subcarriers in accordance with the changed order; and transmitting a codeword generated in accordance with the mapped result to the receiving side. Thus, it is possible to improve packet decoding success probability of the receiving side during initial transmission or retransmission by controlling a type of transmission packets in accordance with feedback information of the receiving side.
