<p>The present invention relates to an ARQ control apparatus and method. According to the present invention, a subscriber station performs initialization by communicating with a base station, and receives wireless link channel quality information; stores an SDU in an SDU buffer when the SDU is transmitted from an upper block, and establishes a connection with the base station for a corresponding service flow; receives QoS information on the service flow, ARQ information, and a CINR, and transmits them to the uplink scheduler; detects a TCP header of the SDU and stores TCP sequence number information; and performs a DSC for controlling an MAC ARQ window size with reference to the QoS information, ARQ information, CINR, and TCP congestion window size.</p> |
