1. A method for transmitting an uplink control channel (physical uplink control channel; PUCCH) in a wireless communication system by a user equipment (UE), the method comprising:
receiving resources corresponding to an enhanced downlink control channel (enhanced physical downlink control channel; EPDCCH) comprising at least one enhanced control channel element (ECCE), from a base station (BS); and
transmitting, to the BS, according to linkage information about the at least one enhanced control channel element (ECCE), resources corresponding to an uplink control channel (PUCCH), the uplink control channel (PUCCH) corresponding to a downlink data channel (physical data shared channel; PDSCH) scheduled by the enhanced downlink control channel (EPDCCH),
wherein the linkage information includes information about an aggregation level set used to decode the enhanced downlink control channel (EPDCCH), and indicates a resource index of the uplink control channel corresponding to an index of the at least one enhanced control channel element (ECCE), according to a minimum value of an aggregation level in the aggregation level set for the enhanced downlink control channel (EPDCCH).
