Abstract: PURPOSE: An integrated automatic repeat request method and a device thereof are provided to obtain synergy effect by mixing advantage between an ARQ method and a HARQ method. CONSTITUTION: An ARQ module(110) executes an ARQ. An HARQ module(120) executes a HARQ. A control module(130) selects one between the ARQ method and the HARQ method based on ARQ information transmission efficiency during an ARQ method based ACK/NAK transmission process when a receiving terminal does not correctly receive a packet. The control module transfers the ACK/NAK through the selected mode. The ARQ information transmission efficiency shows a packet count capable of transmitting during delay time through the ARQ method. The control module transfers the ACK/NAK using the selected mode to the transmitting terminal by controlling the ARQ module and the HARQ module.
