ABSTRACT:
An apparatus and a method for selectively retransmitting data according to a channel state in a wireless communication system are provided. The method includes determining retransmission information of a receiver from feedback information received from the receiver, determining a retransmission scheme for the receiver using the retransmission information of the receiver, and performing a retransmission process with the receiver according to the determined retransmission scheme. In a good channel state, the data is retransmitted using the retransmission scheme to thereby enhance the reliability of the data delivery and the reception performance. In a bad channel state, the data is not retransmitted to thereby reduce a waste of resources in the data retransmission.
