The method for transmitting a receipt acknowledgement in a wireless communication system according to one embodiment of the present invention comprises: a step for receiving an enhanced physical downlink control channel (EPDCCH); a step for determining a resource of a physical uplink control channel (PUCCH) on the basis of the lowest enhanced control channel element (ECCE) index among ECCE indices comprising the EPDCCH, and a HARQ-ACK resource offset (ARO); and a step for transmitting the receipt acknowledgement via the PUCCH resource. In addition, when the receipt acknowledgement related to at least two sub-frames is transmitted in the sub-frame for transmitting the receipt acknowledgement, an aggregation of values enabled by the ARO includes a first ARO value for moving a specific sub-frame PUCCH resource to PUCCH resource region for previous sub-frames of the specific sub-frame PUCCH, and said first ARO value provides a different amount of movement according whether the specific sub-frame is a specific group sub-frame among groups related to at least the two sub-frames. |
