Peak reduction tone allocation techniques

A method of wireless communication at a transmitting device, comprising:

• selecting a location of one or more reserved tones among a plurality of tones based at least in part on signal to noise ratio (SNR) of each of the plurality of tones, wherein selecting the location of the one or more reserved tones among the plurality of tones comprises either:
• choosing a sequence from a table that comprises one or more sequences and each sequence has a fixed allocation for the one or more reserved tones over a frequency domain, or
• receiving an indication, from a receiving device, to transmit the plurality of tones comprising the one or more reserved tones, wherein the location of the one or more reserved tones among the plurality of tones is selected using a specified apparatus based on the indication;
• and
• transmitting data to the receiving device in a subset of the plurality of tones that does not include the one or more reserved tones associated with the selected location.

An apparatus for wireless communication at a receiving device, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive an indication from a transmitting device indicating a location of one or more reserved tones among a plurality of tones within a frequency resource, wherein the location is based, at least in part, on a signal to noise ratio (SNR) for each of the plurality of tones and based on at least one of:
• a sequence from a table, wherein the table comprises one or more sequences and each sequence has a fixed allocation for the one or more reserved tones over a frequency domain, or
• transmitting a second indication to the transmitting device to select the location of the one or more reserved tones among the plurality of tones using a specified apparatus;
• receive data in a subset of the plurality of tones that does not include the one or more reserved tones;
• and
• ignore the one or more reserved tones.
