1. An apparatus for wireless communication, comprising:
a processor;
a transceiver communicatively coupled to the processor; and
a memory communicatively coupled to the processor,
wherein the processor and the memory are configured to:
receive, via the transceiver, control information comprising a set of one or more peak reduction tone (PRT) sequences;
receive, via the transceiver, a resource allocation spanning a plurality of tones;
receive, via the transceiver, a PRT sequence selection parameter for determining a set of the plurality of tones of the resource allocation to be PRTs, based on the set of one or more PRT sequences; and
transmit, via the transceiver, a sum of a data waveform and a peak-to-average-power (PAPR)-reduction waveform, the PAPR-reduction waveform carried on the PRTs to reduce an amplitude of a peak in the data waveform.
