1. A method for wireless communication, comprising:

  • segmenting a transmission slot into a set of symbols;

    identifying a first subset of the set of symbols and a second subset of the set of symbols;

    generating a first waveform for a first symbol of the first subset of symbols based at least in part on whether the first symbol contains control information or reference signal transmissions;

    generating a second waveform for a second symbol of the second subset of symbols by appending a guard interval (GI) to a set of samples containing data to be transmitted in the second symbol and performing a discrete Fourier transform spread frequency division multiplexing (DFT-s-FDM) procedure on the data and GI;

    generating a combination waveform based on the first subset of symbols and the second subset of symbols; and

    transmitting the combination waveform to a receiver.
