1. A method of wireless communication, comprising:
communicating, by a user equipment (UE), peak to average power ratio (PAPR) shaping information, wherein the PAPR shaping information comprises information regarding one or more PAPR shaping resources for a data signal to be processed for transmission;
generating, by the UE, a frequency domain data signal for the data signal;
processing, by the UE, the frequency domain data signal using a PAPR shaping resource of the one or more PAPR shaping resources configured in accordance with information of the PAPR shaping information;
generating, by the UE, a time domain data signal from the frequency domain data signal having been processed using the PAPR shaping resource; and
transmitting, by the UE, the time domain data signal, wherein the time domain data signal as transmitted comprises a Discrete Fourier transform (DFT) spread orthogonal frequency division multiplex (OFDM) (DFT-s-OFDM) signal having PAPR shaping for PAPR reduction provided in accordance with the frequency domain data signal having been processed using the PAPR shaping resource.
