Apparatus and method for retransmission request of packet using arq and harq scheme in radio communication system

The present invention to provide an apparatus and method for a wireless communication system including a hybrid automatic retransmission (HARQ) layer and automatic retransmission (ARQ) layer, a packet retransmission request to provide. The present invention is a local NACK (Local NACK) and the packet loss (Packet Loss) to as quickly as possible using a distinct timer-driven and, HARQ reception failure indicator for detecting control the status report transmission of the message according to the non-receiving packet do. Accordingly, to quickly recover a packet not received to speed in accordance with a packet transmission and reception and prevent unnecessary status report transmission of the message according to the packet not received, has the advantage of efficient use of limited radio resources. ARQ packet, HARQ packet, Local NACK, HARQ NACK / ACK, HARQ reception failure indicator
