Abstract

DATA RETRANSMISSION APPARATUS AND METHOD IN A WIRELESS RELAY COMMUNICATION SYSTEM ARE PROVIDED. IT IS CHECKED WHETHER AN ACKNOWLEDGEMENT (ACK) MESSAGE OR A NEGATIVE ACK (NACK) MESSAGE FOR DATA IS RECEIVED FROM A RELAY STATION (RS), WHICH RECEIVES THE DATA FROM A MOBILE STATION (MS). SCHEDULING INFORMATION FOR TRANSMITTING THE DATA IS TRANSMITTED TO THE RS, WHEN THE ACK MESSAGE IS RECEIVED FROM THE RS. ERRORS ARE CHECKED FOR IN OF THE DATA, WHEN THE DATA IS RECEIVED FROM THE RS. THE RS IS REQUESTED TO RETRANSMIT THE DATA, WHEN THE DATA HAS AN ERROR. ACCORDINGLY, SINCE THE RS RETRANSMITS ONLY THE ERROR-FREE DATA TO THE BS, THE BS CAN ENHANCE THE DATA RELIABILITY.
