Disclosed in the present application is a method for receiving an ACK/NACK (Acknowledgement/Negative Acknowledgement) signal by a terminal in a wireless communication system. More specifically, the method comprises the steps of: transmitting an uplink data signal to a base station; a blind decoding of downlink control information including an ACK/NACK response signal regarding the uplink data signal so as to acquire a decoded signal; and checking the ACK/NACK response signal, corresponding to the terminal, from among the downlink control information. The downlink control information consists of ACK/NACK response signals corresponding to a plurality of terminals.
