Abstract
An apparatus and a method for data retransmission in a multihop relay wireless communication system are provided. The retransmission method includes determining whether an error is detected in data received from an upper node; generating a message indicative of the data error; and sending the message to the upper node at a time that is not appointed with the upper node. Therefore, it is possible to reduce a retransmission delay time that occurs during synchronous retransmission.
