1. A method for transmitting, by a user equipment (UE), acknowledgement/negative acknowledgement (ACK/NACK) information in a carrier aggregation based wireless communication system, comprising:
receiving one or more physical downlink control channel (PDCCH) signals in a subframe (SF) interval of a first frequency division duplex (FDD) cell,
wherein the SF interval of the first FDD cell includes one or more first downlink (DL) SFs of the first FDD cell and one last second DL SF of the first FDD cell;
receiving one or more physical downlink shared channel (PDSCH) signals indicated by the one or more PDCCH signals in the SF interval of the first FDD cell; and
transmitting ACK/NACK information corresponding to the one or more PDSCH signals through a physical uplink control channel (PUCCH) in a second uplink (UL) SF of the first FDD cell corresponding to the last second DL SF of the first FDD cell,
wherein one or more first UL SFs corresponding to the one or more first DL SFs of the first FDD cell are used for ACK/NACK transmission for a second FDD cell, and not used for ACK/NACK transmission for the first FDD cell,
wherein, when at least one PDSCH signal is received in the one or more first DL SFs of the first FDD cell, the ACK/NACK information includes ACK/NACK responses for all DL SFs of the SF interval of the first FDD cell and is transmitted in the second UL SF of the first FDD cell by using a PUCCH resource allocated by an upper layer, and
wherein, when one PDSCH signal is received only in the last second DL SF of the first FDD cell, the ACK/NACK information includes an ACK/NACK response only for the last second DL SF of the first FDD cell and is transmitted in the second UL SF of the first FDD cell by using a PUCCH resource linked to an index of a resource through which a PDCCH signal corresponding to the PDSCH signal is transmitted.
