Abstract
Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus, such as a wireless communication device, selects a set of PRTs based on a deterministic pseudo-random tone selection algorithm, such as quadratic sampling, cubic sampling, or Fibonacci-type sampling. The apparatus determines a PAPR reduction waveform for transmission on the PRTs and transmits a data waveform multiplexed with the PAPR reduction waveform on resources corresponding to the resource allocation. Other aspects, embodiments, and features are also claimed and described.
