1. A method for wireless communication at a user equipment (UE), comprising:
receiving a control signal indicating that the UE is to utilize one or more peak reduction tones for an uplink transmission period;
identifying, from a set of allocated resources, first subcarriers for transmitting a data signal;
identifying the one or more peak reduction tones of a peak-cancellation signal based at least in part on a Costas array, wherein the one or more peak reduction tones are identified within one or more resource blocks of the set of allocated resources based at least in part on non-zero values within one or more columns of the Costas array corresponding to the one or more resource blocks;
generating an uplink waveform based at least in part on the data signal and the peak-cancellation signal; and
transmitting the uplink waveform during the uplink transmission period.
