1. A method of transmitting acknowledgement/negative-acknowledgement (ACK/NACK) information by a user equipment (UE) in a wireless communication system, the method comprising:
receiving downlink control information (DCI) through a downlink (DL) control channel from an eNB; and
transmitting ACK/NACK information corresponding to the DCI through an uplink (UL) control channel resource,
wherein an index of the UL control channel resource is determined according to a first parameter and a second parameter,
wherein the first parameter includes at least one of a first offset value or a second offset value,
wherein the first offset value corresponds to an index of the antenna port used for the DL control channel transmission,
wherein the second offset value corresponds to a predetermined field of a DCI format of the DL control channel, and
wherein the second parameter includes a lowest Enhanced Control Channel Element (ECCE) index used for the DL control channel transmission.
