According to one aspect of the present invention, a user terminal has a transmission section that is capable of transmitting a plurality of waveforms including a first waveform and a second waveform while switching therebetween, wherein the first waveform is based on a first transmission scheme and the second waveform is based on a second transmission scheme, and transmits the first waveform at a given timing, by using a given cell, and a control section that calculates a power headroom for the second waveform, which is one of the plurality of waveforms and which is not transmitted at the given timing. According to one aspect of the present invention, communication can be continued adequately even when communication is performed by using multiple waveforms.
