Peak reduction tone allocation techniques

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

• communicating with a receiving device an indication to apply peak to average power ratio (PAPR) reduction for a data transmission;
• applying a first PAPR reduction signal and a second PAPR reduction signal to the data transmission to reduce at least one signal peak of the data transmission to yield a transmission signal, wherein the first PAPR reduction signal comprises a first set of peak reduction tones (PRTs) that does not overlap with data tones and the second PAPR reduction comprises a second set of PRTs that overlaps with the data tones and does not overlap with reserved tones;
• and
• transmitting the transmission signal to the receiving device.

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

• a memory;
• and
• at least one processor, communicatively connected to the memory, the at least one processor configured to:
• receive a data transmission from a transmitting device, wherein at least one signal peak of the data transmission is reduced by a combination of a first peak to average power ratio (PAPR) reduction signal and a second PAPR reduction signal at the transmitting device, wherein the first PAPR reduction signal comprises a first set of peak reduction tones (PRTs) within a plurality of tones, and the plurality of tones further comprise one or more data tone and the first set of PRTs does not overlap with the one or more data tone, and wherein the second PAPR reduction signal comprises a second set of PRTs within the plurality of tones, and at least a part of the second set of PRTs overlaps with the one or more data tone, and the second set of PRTs does not overlap with the first set of PRT;
• identify a location, a magnitude and a phase of the at least one signal peak of the data transmission that is reduced based on a location of the first set of PRTs or the second set of PRTs or the one or more data tones or a combination thereof;
• and
• regenerate at least a portion of the at least one signal peak of the data transmission that is reduced based at least in part on the identified location, the magnitude and the phase of the at least one signal peak of the data transmission that is reduced.
