Provided is a terminal device capable of efficiently assigning transmission power. A transmission power control method of a terminal device that communicates simultaneously with a plurality of cells, wherein the terminal device is provided with: a control signal processing unit which receives a control signal reporting that among the connected plurality of cells, at least one cell is brought into an off state in which data communication is not temporarily performed; and a transmission power control unit which if determining that the total value of required transmission powers of the plurality of cells exceeds the maximum transmission power of the terminal device when setting transmission power in each of the connected plurality of cells, refers to the contents of the report by the control signal, and determines the order of priority in which the transmission power is assigned to each of channels and signals to be transmitted in the connected plurality of cells, and the transmission power control unit assigns power to a sounding reference signal to be transmitted in a cell that is not in the off state with higher priority than a sounding reference signal to be transmitted in the cell in the off state. |
