Methods and systems for communicating in a wireless network include reducing the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) subcarriers based on channel state information. Reducing the PAPR may include observing channel state information such as channel impulse response, interference or noise of a receive channel, selecting subcarriers for transmission likely to be detrimentally affected by the channel state and applying a known PAPR reduction technique, such as tone reservation PAPR reduction or tone injection PAPR reduction to the selected subcarriers. Various embodiments and variants are also disclosed.
