Provided is a user equipment in a radio communication system including a base station and the user equipment. The user equipment includes: an acquisition unit that acquires a first transmission power parameter in a case of using OFDM in an uplink and a second transmission power parameter in a case of using DFT-s-OFDM in the uplink; and a control unit that controls transmission power of an uplink signal by using the first transmission power parameter in a case of using ODFM in the uplink, and controls transmission power of the uplink signal by using the second transmission power parameter in a case of using DFT-s-OFDM in the uplink.
