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.

Abstract: A method is provided for a base station to transmit downlink control information to a relay through a Relay-Physical Downlink Control Channel (R-PDCCH). The base station transmits one or more candidate positions for the R-PDCCH. The base station further determines, based on the one or more candidate positions, a Virtual Resource Block (VRB) set for the R-PDCCH. Moreover, the base station transmits the downlink control information to the relay through the R-PDCCH. The one or more candidate positions are within the VRB set including at least one VRB, and a candidate position for the R-PDCCH of a higher aggregation level includes a combination of 2 adjacent candidate positions among candidate positions for the R-PDCCH of a lower aggregation level.
