Abstract:
A method and apparatus for performing Automatic Retransmission reQuest (ARQ) on packet data in a mobile communication system. The method includes receiving from a transmission entity performing ARQ, by a reception entity, a status report message including a Non-Acknowledged (NACK) signal for the packet data transmitted to the reception entity, and generating time information of the NACK signal; comparing, by the transmission entity, the generation time information with transmission complete time information for the packet data; and determining whether to retransmit the packet data depending on the comparison result, and performing retransmission of the packet data according to the determination step.
