Title
(EN) PEAK REDUCTION TONE ALLOCATION TECHNIQUES
Abstract
(EN)

A transmitting device communicates with a receiving device an indication to apply PAPR reduction for a data transmission. The transmitting device applies 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, where the first PAPR reduction signal includes a first set of PRTs that does not overlap with data tones and the second PAPR reduction includes a second set of PRTs that overlaps with the data tones and does not overlap with reserved tones. The transmitting device transmits the transmission signal to the receiving device.
