摘要

Transmission power for an uplink signal is efficiently set. There are provided a reception unit 105 that receives from a base station device a first transmission power control command, a second transmission power control command, first information indicating whether or not accumulation of first transmission power control commands is enabled and second information indicating whether or not accumulation of second transmission power control commands is enabled, a transmission power setting unit 1015 that sets a first parameter value based on the first information and the first transmission control command, sets a second parameter value based on the second information and the second transmission control command, sets a first transmission power for a first reference signal using at least using a first parameter, and sets a second transmission power for a second reference signal using at least a second parameter, and a transmission unit 107 that transmits the first reference signal at the first transmission power and the second reference signal at the second transmission power to the base station device.
