Abstract
An apparatus for retransmitting data using hybrid automatic retransmission request (HARQ) in a mobile communication system. A radio network controller (RNC) determines maximum waiting time for retransmission of the data, and transmits the determined maximum waiting time to a Node B and a user equipment (UE). The Node B (a) receives the maximum waiting time and transmitting the data to the UE; (b) upon detecting a retransmission request for the data from the UE, retransmits the data and sets the maximum waiting time; and (c) upon detecting a second retransmission request for the data due to abnormal receipt of the retransmitted data from the UE after a lapse of the maximum waiting time, prevents retransmission of the data. The UE (a) receives the maximum waiting time; (b) if an error exists in data received from the Node B, transmits a retransmission request for the data to the Node B and sets the maximum waiting time; and (c) waits for the retransmitted data only for the maximum waiting time.
