SLOT STRUCTURE DESIGN USING GUARD INTERVALS IN A SINGLE CARRIER WAVEFORM
First Claim
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.

Abstract
Methods, systems, and devices for wireless communication are described for slot structures using guard intervals in a single carrier waveform. Techniques provide for generating a first waveform for control information or reference signal transmissions in a first subset of symbols, and generating a second waveform for data to be transmitted in a second subset of symbols. A combination waveform may be generated based on the first and second waveforms that is transmitted to a receiver, such as by concatenating the first and second waveforms. The first waveform may be generated by appending a guard interval (GI) sequence to a reference signal or control information, and performing a discrete Fourier transform spread frequency division multiplexing (DFT-s-FDM) procedure. The second waveform may be generated by appending the GI to data to be transmitted in each symbol of the second subset of symbols, and performing the DFT-s-FDM procedure.
