- H04L 27/2621: {Reduction thereof using phase offsets between subcarriers}
- H04L 5/0007: {the frequencies being orthogonal, e.g. OFDM(A) or DMT}
- H04L 25/022: {of frequency response}
- H04L 1/0013: {Rate matching, e.g. puncturing or repetition of code symbols}

## Abstract

An access point may include a processing device configured to: identify a puncturing pattern for a channel width of a physical layer protocol data unit (PPDU) of a transmit signal; compute one or more tone rotation patterns using one or more tone rotation pattern parameters; and select a tone rotation pattern of the one or more tone rotation patterns based on the puncturing pattern for the channel width to minimize a peak to average power ratio (PAPR) of the transmit signal. The access point may include a transceiver configured to transmit the transmit signal to a wireless device based on the tone rotation pattern.

## Claims

### Claim 1

An access point, comprising:
a processing device configured to:
identify a puncturing pattern for a channel width of a physical layer protocol data unit (PPDU) of a transmit signal;
compute one or more tone rotation patterns using one or more tone rotation pattern parameters; and
select a tone rotation pattern of the one or more tone rotation patterns based on the puncturing pattern for the channel width to minimize a peak to average power ratio (PAPR) of the transmit signal;
a transceiver configured to transmit the transmit signal to a wireless device based on the tone rotation pattern.
