Abstract:
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving a physical downlink control channel (PDCCH); receiving a physical downlink shared channel (PDSCH) indicated by the PDCCH; and transmitting ACK/NACK for the PDSCH via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the number of aggregated carriers into account.
