Abstract:
The present invention discloses a method for transmitting a reception acknowledgement response in a wireless communication system. The method includes receiving an enhanced physical downlink control channel (EPDCCH), determining a physical uplink control channel (PUCCH) resource based on a lowest one of enhanced control channel element (ECCE) indexes configuring the EPDCCH and a HARQ-ACK resource offset (ARO), and transmitting a reception acknowledgement response through the PUCCH resource. When a reception acknowledgement response related to two or more subframes is transmitted in a subframe for transmission of the reception acknowledgement response, a set of possible values for the ARO includes a first ARO value to shift a PUCCH resource of a specific subframe to a PUCCH resource region for at least one subframe prior to the specific subframe. The first ARO value provides a different shift amount depending on a group having the specific subframe among groups related to the two or more subframes.
