Abstract

The present invention is designed so that, when the CP-OFDM waveform is supported in the UL in addition to the DFT-spread OFDM waveform, UL transmission can still be controlled adequately. According to the present invention, a user terminal has a transmission section that 5 transmit an uplink shared channel (PUSCH), and a control section that controls, based on the waveform that is used for an uplink shared channel scheduled by downlink control information scrambled by a first indicator, the waveform to use for an uplink shared channel that is scheduled by downlink control information scrambled by a second indicator. 10 FIG. 3
