Abstract
[Object] To cause the transmission efficiency of the entire system to be significantly improved. [Solution] A terminal device configured to perform communication with a base station device, including: a wireless transmitting unit configured to transmit an uplink channel using a first signal waveform or a second signal waveform on the basis of control information notified by the base station device. The first signal waveform is a multicarrier signal, and the second signal waveform is a single carrier signal.
Claims17
A terminal device configured to perform communication with a base station device, comprising:
- a transmitter;
- and
- processing circuitry configured to control the transmitter to transmit an uplink channel using a first signal waveform or a second signal waveform, wherein the first signal waveform is a signal which is generated without performing a predetermined conversion process, and the second signal waveform is a signal which is generated by performing the predetermined conversion process, wherein:
- in a case where the uplink channel is a predetermined control channel, the processing circuitry controls the transmitter to transmit the uplink channel using the second signal waveform,
- in a case where the uplink channel is a predetermined shared channel, the processing circuitry controls the transmitter to transmit the uplink channel using either the first signal waveform or the second signal waveform based on control information notified from the base station to the terminal device, and
- in a case where the control information is not set, a signal waveform for the predetermined shared channel is determined based on broadcast information notified from the base station to the terminal device.
