When communication is performed in a broad frequency band compositely using a plurality of continuous and/or non-continuous frequency bands (carrier elements), data (information) is transmitted in a mobile station device with transmission power suppressed to be low. A base station device assigns, to the mobile station device, a first physical uplink control channel for transmitting first control information, and assigns, to the mobile station device, a plurality of second physical uplink control channels for transmitting second control information with a sub frame that is the same as a sub frame to which the first physical uplink control channel is assigned. The mobile station device selects any one of the plurality of second physical uplink control channels, and transmits, to the base station device, the first control information and the second control information together or the second control information. |
