Abstract
(EN) A transmitting device applies a first MCS to a first set of data tones that overlaps with a first set of PRTs within a plurality of tones, the first set of PRTs being associated with a first PAPR reduction signal. The transmitting device applies a second MCS to a second set of data tones that overlaps with a second set of PRTs within the plurality of tones, the second set of PRTs being associated with a second PAPR reduction signal. The transmitting device can transmit a transmission signal comprising the first set of data tones and the second set of data tones, the transmission signal using a waveform based at least in part on the first PAPR reduction signal and the second PAPR reduction signal.
(FR) Un dispositif de transmission applique un premier MCS à un premier ensemble de tonalités de données qui chevauche un premier ensemble de PRT à l'intérieur d'une pluralité de tonalités, le premier ensemble de PRT étant associé à un premier signal de réduction de PAPR. Le dispositif de transmission applique un second MCS à un second ensemble de tonalités de données qui chevauche un second ensemble de PRT à l'intérieur de la pluralité de tonalités, le second ensemble de PRT étant associé à un second signal de réduction de PAPR. Le dispositif de transmission peut transmettre un signal de transmission comprenant le premier ensemble de tonalités de données et le second ensemble de tonalités de données, le signal de transmission utilisant une forme d'onde basée au moins en partie sur le premier signal de réduction de PAPR et le second signal de réduction de PAPR.
