1. A terminal device configured to perform communication with a base station device, comprising:
processing circuitry configured to control a receiver and a transmitter;
the receiver configured to receive a control information for an uplink channel from the base station; and
the transmitter configured to transmit the uplink channel using a first signal waveform or a second signal waveform, based on the control information, wherein
the first signal waveform is signal which is generated without performing a discrete Fourier transform conversion process, and the second signal waveform is a signal which is generated with performing the discrete Fourier transform conversion process, and
in a case where the second signal waveform is used by the transmitter, only a single multiple-input and multiple-output (MIMO) layer transmission is used for the uplink channel.
