Tone reservation for peak to average power ratio reduction

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a resource allocation indicating a set of transmission tones comprising a set of data tones and a set of peak reduction tones (PRTs), wherein the resource allocation indicates locations for the set of data tones and locations for the set of PRTs within a particular bandwidth, wherein the locations for the set of PRTs are arranged relative to the locations for the set of data tones according to a PRT sequence, and wherein the PRT sequence comprises a plurality of contiguous PRTs arranged relative to a plurality of contiguous data tones or a pseudo-random pattern generated using a pseudo-random number generator; and transmit a data transmission using a waveform based at least in part on the resource allocation. Numerous other aspects are provided.
