1. A mobile station device that communicates with a base station device by using a plurality of serving cells, the plurality of serving cells includes a primary cell and at least one secondary cell, the mobile station device comprising:

  • receiving circuitry that receives a first parameter and a second parameter; and

    transmitting circuitry that transmits Channel State Information (CSI) multiplexed with Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) in a subframe without a physical uplink shared channel in a case of collision between the HARQ-ACK and the CSI in the subframe without the physical uplink shared channel, whereinbased on the HARQ-ACK corresponding to a physical downlink shared channel transmission only on the primary cell and the first parameter indicating simultaneous transmission of HARQ-ACK and CSI, the CSI is multiplexed with the HARQ-ACK using the first physical uplink control channel format, andbased on the HARQ-ACK corresponding to a physical downlink shared channel transmission on the secondary cell and the second parameter indicating simultaneous transmission of HARQ-ACK and CSI using the second physical uplink control channel format, the CSI is multiplexed with the HARQ-ACK using the second physical uplink control channel format.
