1. A terminal device configured to perform communication with a base station, comprising:
a wireless transmitter configured to transmit an uplink channel using a first signal waveform or a second signal waveform, wherein
the first signal waveform is a signal generated without performing a predetermined conversion process, and the second signal waveform is a signal generated by performing the predetermined conversion process,
in a case where the uplink channel is a predetermined control channel, the second signal waveform is used for transmitting the uplink channel, and
in a case where the uplink channel is a predetermined shared channel, either the first signal waveform or the second signal waveform is used for transmitting the uplink channel based on control information uniquely notified from the base station to the terminal device.
