Abstract

A mobile station device includes: a management unit managing generation of uplink control information; a transmission power parameter setting unit setting a value of a parameter relevant to transmission power in accordance with the number of information bits of receipt acknowledgement and scheduling request, when the management unit generates the receipt acknowledgement which is uplink control information indicating positive or negative acknowledgement for downlink data and the scheduling request which is uplink control information indicating whether to request resource allocation; and a transmission processing unit controlling, by means of the parameter value set by the transmission power parameter setting unit, the transmission power for a physical uplink control channel used for transmitting a signal generated from the information bits of the receipt acknowledgement and the scheduling request, and transmitting the signal to a base station device using the physical uplink control channel with the controlled transmission power.
