US 12,587,424 B2 · Rearrangement scheme for low peak-to-average power ratio Faster-Than-Nyquist waveform

Abstract

Methods, systems, and devices for a rearrangement scheme for a Faster-than-Nyquist (FTN) waveform are described. An example method includes a user equipment (UE) receiving a phase rearrangement indication from a network entity, the phase rearrangement indication indicating one or more parameters associated with a phase rearrangement process for a FTN discrete Fourier transformation spread orthogonal frequency division multiplexing (DFT-s-OFDM) transmission scheme. The method may also include transmitting a signal based at least in part on the phase rearrangement indication and according to the DFT-s-OFDM transmission scheme. Another example method includes a network entity transmitting a phase rearrangement indication indicating one or more parameters associated with a phase rearrangement process for a DFT-s-OFDM transmission scheme and receiving a signal based at least in part on the phase rearrangement indication and according to the DFT-s-OFDM transmission scheme.
