Assignee: SONY GROUP CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A base station configured to perform communication with a terminal device, comprising:
a receiver configured to receive an uplink channel transmitted using a first signal waveform or a second signal waveform from the terminal device; and
a transmitter configured to transmit control information to the terminal device, wherein
the first signal waveform is a signal generated without performing a predetermined conversion process, and the second signal waveform is a signal uenerated by performing the predetermined conversion process,
in a case where the uplink channel is a predetermined control channel, the uplink channel is transmitted from the terminal device using the second signal waveform, and
in a case where the uplink channel is a predetermined shared channel, the uplink channel is transmitted from the terminal device using either the first signal waveform or the second signal waveform based on the control information transmitted to the terminal device.
