PURPOSE: A method for performing HARQ in a wireless communication system is provided to set an amount of reserved ACK/NACK resources semi-statically. CONSTITUTION: A downlink allocation is received in a first sub frame(S100). The downlink allocation is transmitted based on a CCE(Control Channel Element) that is a resource unit with the index logically. The downlink data is received on a downlink shared channel in a first sub frame(S110). The downlink shared channel is allocated according to the downlink allocation. An ACK/NACK signal indicating the successful or unsuccessful reception of the downlink data(S120). The ACK/NACK signal or representative ACK/NACK signal is transmitted using the uplink resource of a subset in a second sub frame(S130). The sub set is mapped in the first sub frame. One of the uplink resources is mapped to the plurality of CCEs in the first sub frame. |
