According to an embodiment of the present invention, in a method in which a terminal transmits a reception confirmation response in a wireless communication system, downlink control information (DCI) is acquired through an EPDCCH (Enhanced Physical Downlink Channel). Receiving a downlink data via PDSCH (Physical Downlink Shared Channel), and transmitting a reception confirmation response to the downlink data using a PUCCH (Physical Uplink Control Channel) resource, the PDSCH. Is transmitted on the SCell (Secondary Cell), and the PDSCH is the EP. When instructed by the DCCH, the PUCCH resource is a method of transmitting a reception confirmation response determined based on a TPC (Transmit Power Control) field included in the DCI.
