ABSTRACT:
Disclosed is an apparatus and method for supporting automatic repeat request (ARQ) in a high-speed wireless packet data communication system. A mobile station receives control information including a subpacket identifier (SP_ID) representing the sequence of a subpacket, the size of an encoder packet (EP_SIZE), and a sequence identifier (AI_SN) that is toggled each time a new encoder packet is transmitted, while receiving one of a plurality of subpackets generated by segmenting a bit stream acquired by encoding a transmission encoder packet. The mobile station determines whether it will perform a decoding process caused by initial transmission or a decoding process caused by retransmission on the received subpacket, based on the control information.
