Abstract
A method for requesting packet retransmission in a wireless communication system is provided. The method includes checking, by a receiving-side Automatic Retransmission reQuest (ARQ) layer, sequence numbers of received packets to determine whether there is any missing packet, and starting a first timer in association with the missing packet; stopping the first timer upon receiving an Hybrid ARQ (HARQ) reception failure indicator corresponding to the missing packet, provided from a receiving-side HARQ layer; and stopping generation of a status report message corresponding to the missing packet, and waiting for an ARQ packet corresponding to the missing packet, retransmitted from a transmitting-side ARQ layer.
