APPARATUS AND METHOD FOR DATA RETRANSMITTING IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An apparatus and a method for retransmitting data in a wireless communication system are provided to improve the throughput of a system by controlling the operation of automatic repeat request(ARQ) considering the operational state of hybrid-ARQ(HARQ). CONSTITUTION: The operational state information of an HARQ module(212) is confirmed according to the decay time of an ARQ timer(253, 255). Considering the operational state information of the HARQ module, the delay the generation of NACK information is determined(257). While the NACK information is delayed, the generation of the NACK information is delayed considering the operational state information of the HARQ module regardless of the decay of the ARQ timer.
