Title: Method and apparatus for transmitting uplink control signal in wireless communication system

Abstract: The present invention relates to a method for a terminal for transmitting an uplink control signal, i.e., an ACK/NACK (Acknowledgement/Negative-ACK) signal, in a wireless communication system. In particular, the method comprises: mapping part of the ACK/NACK signals to selection information, which is composed of a combination of message areas and reference signal areas; independently selecting one message area and one reference signal from a plurality of control channel resources that are located in the same resource block, based on the mapped selection information; allocating the selected message area to the other ACK/NACK signals; and transmitting the ACK/NACK signal to a base station by using the selected message area and the selected reference signal area.
