Abstract

A wireless transmit receive unit (WTRU) may receive a physical control channel transmission including control information for a data transmission. The WTRU may determine between a first type of waveform and a second type of waveform for the data transmission based on at least a format of the control information. Further, the WTRU may transmit the data transmission using the determined type of waveform. In an example, the type of waveform is further determined based on indication information included in the physical control channel transmission. Also, the first type of waveform may be an orthogonal frequency division multiplexing (OFDM) waveform and the second type of waveform is a discrete Fourier transform spread OFDM (DFT-S-OFDM) waveform. Moreover, the determination between the first type of waveform and the second type of waveform may be further based on an indication to use the DFT-S-OFDM waveform.
