Claim:
1. A mobile station for communication using carrier aggregation, comprising: a secondary cell state management circuitry configured to manage whether a state of a secondary cell is an activation state or a deactivation state; a transmission control circuitry configured to stop transmission of uplink control information on a physical uplink control channel in a first secondary cell, when the state of the first secondary cell managed by the secondary cell state management circuitry is the deactivation state at a timing of transmission of the physical uplink control channel in the first secondary cell; and a resource management circuitry configured to manage a resource for a physical uplink shared channel, wherein the transmission control circuitry controls transmission such that the uplink control information to be transmitted on the physical uplink control channel in the first secondary cell is transmitted using the physical uplink shared channel, when a resource for the physical uplink shared channel is available at the timing of transmission of the physical uplink control channel in the first secondary cell.
