PEAK REDUCTION TONE (PRT) SELECTION

Abstract:

Aspects of the disclosure relate to selection and use of peak reduction tones (PRTs) including obtaining a predetermined sequence of PRTs corresponding to a set of granted resources including a plurality of tones, mapping a set of data to a first subset of the plurality of tones outside of the predetermined sequence of PRTs and mapping a set of PRTs to a second subset of the plurality of tones within the predetermined sequence of PRTs. At least one peak of a time domain representation of the first subset of the plurality of tones is canceled using a time domain representation of the second subset of the plurality of tones. A transmitted waveform comprising the first subset of the plurality of tones and the second subset of the plurality of tones is transmitted.
