Transmitting sounding reference signals in new radio

A method for wireless communications by a base station (BS), comprising:

• determining whether a user equipment (UE) is to transmit a sounding reference signal (SRS) using a discrete Fourier transform (DFT) spread orthogonal frequency domain multiplexing (DFT-S-OFDM) waveform or a cyclic prefix orthogonal frequency domain multiplexing (CP-OFDM) waveform;
• sending an indication of the determined waveform to the UE;
• and
• processing the SRS, based on the determined waveform.

An apparatus for wireless communications, comprising:

• a processor configured to:
• determine whether to transmit a sounding reference signal (SRS) using a discrete Fourier transform (DFT) spread orthogonal frequency domain multiplexing (DFT-S-OFDM) waveform or a cyclic prefix orthogonal frequency domain multiplexing (CP-OFDM) waveform;
• and
• cause the apparatus to transmit the SRS using the determined waveform;
• and
• a memory coupled with the processor.
