Abstract:
Aspects presented herein may improve the efficiency and performance of the tone reservation PAPR reduction technique by allocating peak reduction tone based at least in part on a channel condition, such as based on the signal to noise ratio of the channel. In some aspects, a transmitting device measures a signal to noise ratio for a plurality of tones within a frequency resource. The transmitting device selects a location of one or more reserved tones (e.g., peak reduction tones) among one or more tones based at least in part on an SNR for one or more tones. The transmitting device transmits data to a receiving device in a subset of the plurality of tones that does not include the one or more peak reduction tones. Other aspects and features are also disclosed.
