Abstract
An apparatus and method for retransmitting data in a wireless communication system are provided. The method includes transmitting data to at least one lower node, temporarily storing the data transmitted to the lower node, if ACKnowledgement (ACK) information of a relay link is not received for a predetermined time after data transmission or if the ACK information of the relay link is received from a lower Relay Station (RS), identifying if error occurrence information of an access link is received from the lower RS, and, if the ACK information of the access link is received from the lower RS, recognizing that data transmission to a Mobile Station (MS) succeeds.
