ABSTRACT:
A retransmission method and apparatus performed in a transmitter of a mobile communication system supporting a Hybrid Automatic Retransmission reQuest (HARQ) operation and an Automatic Retransmission request (ARQ) operation for retransmission of a packet are provided. At least one ARQ entity generates at least one ARQ packet, and an HARQ entity transmits an HARQ packet including the at least one ARQ packet to a receiver, and transmits a local NACK signal indicating transmission fail of the ARQ packet to a corresponding ARQ entity, if the HARQ packet fails in transmission.
