Method of transmitting uplink control signals in wireless communication system

A method for transmitting uplink control signals in a wireless communication system is provided to enhance efficiency of resource by utilizing an existing resource. In a transmitter(100), an ACK(Acknowledgement)/NACK(Negative Acknowledgement) resource for transmitting an ACK/NACK signal for HARQ(Hybrid Automatic Repeat Request) of a downlink data is prepared on an uplink control channel. A scheduling request resource is prepared, and transmits the ACK/NACK signal and a scheduling request from one sub frame to the uplink control channel. The ACK/NACK signal is transmitted to the uplink control channel set as the scheduling request resource for positively transmitting the scheduling request. The ACK/NACK signal is transmitted to the uplink control channel set as the ACK/NACK resource for negatively transmitting the scheduling request. The sub frame includes two slots. The slot includes a plurality of SC-FDMA(Single Carrier-Frequency Division Multiple Access) symbols.
