A method for receiving ACK/NACK information transmitted in response to a downlink transmission. The method according to one embodiment includes transmitting one or more relay physical downlink control channels (R-PDCCHs); transmitting the downlink transmission according to the one or more R-PDCCHs in a downlink subframe set including M downlink subframes, where M is a positive integer; and receiving ACK/NACK information for the downlink transmission in the downlink subframe set. The downlink subframe set and the uplink subframe are configured for a time division duplex (TDD). The one or more R-PDCCHs are control channels different from a physical downlink control channel (PDCCH). N physical uplink control channel (PUCCH) resources respectively having indexes 0, 1, 2, . . . , and N−1 are configured by a higher layer, where N is a positive integer and M≦N. Each of M PUCCH resources corresponds to each of the M downlink subframes. |

1. A method for receiving acknowledgement/negative acknowledgement (ACK/NACK) information transmitted in response to a downlink transmission in a base station (BS) of a wireless communication system, the method comprising:
transmitting, by the BS to a relay node (RN), one or more relay physical downlink control channels (R-PDCCHs) for scheduling the downlink transmission; transmitting, by the BS to the RN, the downlink transmission according to the one or more R-PDCCHs in a downlink subframe set including M downlink subframes, where M is a positive integer; and receiving, by the RS from the RN, ACK/NACK information for the downlink transmission in the downlink subframe set in one uplink subframe associated with the downlink subframe set, wherein the downlink subframe set and the uplink subframe are configured for a time division duplex (TDD), wherein the one or more R-PDCCHs are control channels different from a physical downlink control channel (PDCCH), wherein N physical uplink control channel (PUCCH) resources respectively having indexes 0, 1, 2, . . . , and N−1 are configured by a higher layer, where M≦N and N is a positive integer, and wherein each of M PUCCH resources respectively having the indexes 0, 1, 2, . . . , and M−1 among the configured N PUCCH resources corresponds to each of the M downlink subframes. |
