Multi-symbol self-contained waveform design

A method for wireless communications, comprising:

• receiving a waveform formed by one or more reference signal symbols and one or more data symbols, the waveform contained between a beginning boundary and an ending boundary with a duration equal to a total length of the one or more reference signal symbols and the one or more data symbols;
• performing a fast Fourier transform (FFT) on the waveform in symbol length window increments to generate FFT output;
• and
• demodulating data from the FFT output.

An apparatus for wireless communications, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify that a waveform to be generated for a scheduled transmission is formed by one or more reference signal symbols and one or more data symbols, the waveform to be contained between a beginning boundary and an ending boundary with a duration equal to a total length of the one or more reference signal symbols and the one or more data symbols;
• generate the waveform by inserting a guard internal in the one or more reference signal symbols and the one or more data symbols to enable a receiver to perform a fast Fourier transform (FFT) for each of the one or more reference signal symbols and the one or more data symbols;
• and
• transmit the waveform between the beginning boundary and the ending boundary.
