    • A method for retransmitting high-speed packet data in a transmission apparatus of a mobile communication system that simultaneously performs Automatic Retransmission reQuest (ARQ) that retransmits an ARQ packet reconfigured by allocating a sequence number to data delivered from an upper layer, and Hybrid Automatic Retransmission reQuest (HARQ) that multiplexes a plurality of ARQ packets into one HARQ packet and performs repeated retransmission on the HARQ packet within a maximum retransmission limit value. A transmitting HARQ entity checks a missing ARQ packet and sends a Negative Acknowledgement (NACK) for the missing ARQ packet to a transmitting ARQ entity. The transmitting ARQ entity receives an Acknowledged (ACK) for ARQ packets from a receiving ARQ entity, detects at least one missing ARQ packet according to the NACK and the ACK, configures a retransmission packet with the detected ARQ packet, and retransmits the retransmission packet.
