Abstract: Technology for a base station operable to encode guard interval (GI) discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (OFDM) (GI-DFT-s-OFDM) data symbols for transmission to a user equipment (UE) is disclosed. The base station can identify GI-DFT-s-O 5 FDM data symbols for transmission to the UE. The base station can encode the GI-DFT-s-OFDM data symbols for transmission to the UE in a subframe. The subframe can be in accordance with a flexible subframe structure that begins with a demodulation reference signal (DMRS) sequence followed by a GI sequence in a first symbol of the subframe. The subframe can further comprise one or 10 more subsequent symbols in the subframe that each include a GI-DFT-s-OFDM data symbol followed by a GI sequence.
