A method and mobile station for transmitting uplink response signal are provided. A method for transmitting uplink response signal in a multi-carrier communication system is provided, in the multi-carrier communication system, each uplink carrier is associated with a group of downlink carriers, the group of downlink carriers are part of all downlink carriers in the multi-carrier communication system. The method includes distributing uplink control channel resource for each downlink carriers associated with an uplink main carrier in the uplink main carrier; according to a response signal state, selecting uplink control channel resource from the distributed uplink control channel resource for transmitting uplink response signal and selecting modulated symbol mapping; and transmitting the uplink response signal by using the selected uplink control channel resource and the modulated symbol mapping.
