Abstract:
1. A method for transmitting acknowledgement (ACK)/negative ACK (NACK) responses in a wireless communication system, the method comprising: receiving a plurality of downlink data channels over multiple downlink component carriers from a base station; determining the ACK/NACK responses for the plurality of downlink data channels; allocating uplink resources to the ACK/NACK responses; and transmitting the ACK/NACK responses using the uplink resources via one uplink component carrier to the base station, wherein the uplink resources comprise a legacy physical uplink control channel (PUCCH) resource and a new PUCCH resource, and wherein allocating uplink resources to the ACK/NACK responses comprises: allocating the legacy PUCCH resource to the ACK/NACK responses which are transmitted for a first time, and allocating the new PUCCH resource to the ACK/NACK responses which are transmitted successively after the allocating of the legacy PUCCH resource.
