The present application relates to a method for enabling a terminal to transmit an uplink ACK/NACK (Acknowledgement/negative ACK) response to a base station in a time-division multiplexing wireless communication system. Specifically, the method includes the steps of: receiving a setting for an uplink-downlink subframe from the base station; receiving downlink control information and downlink data information scheduled through the downlink control information, from the base station based on the setting for the uplink-downlink subframe; and transmitting an ACK/NACK response for the downlink data information to the base station, wherein the subframe to which the ACK/NACK response is transmitted is determined according to whether an ending symbol of the downlink control information is after a particular symbol of the sub-frame for receiving the downlink control information.
