1. A base station device that communicates with a first terminal device that transmits first data, the base station device comprising:
a controller configured to determine whether a calculation method for a single term among a plurality of terms included in an equation for determining a transmission power of the first terminal device is either a first method or a second method, the first method using a relative value based on a previous value of the single term, the second method using an absolute value that is irrelevant to the previous value of the single term; and
a transmitter configured to transmit, to the first terminal device, notification information for notifying the calculation method determined by the controller, wherein
the controller is further configured to select, according to a type of signal transmitted by the first terminal device being a first type, the calculation method to determine the transmission power of the first terminal device from the first method and the second method, and
the controller is further configured to select, according to the type of signal transmitted by the first terminal device being a second type different from the first type, the calculation method to determine the transmission power of the first terminal device from the first method and the second method.
