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 P APR 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.
(FR) Un dispositif de transmission communique avec un dispositif de réception une indication d'appliquer une réduction de PAPR pour une transmission de données. Le dispositif de transmission applique un premier signal de réduction de PAPR et un second signal de réduction de PAPR à la transmission de données afin de réduire au moins un pic de signal de la transmission de données de sorte à obtenir un signal de transmission, le premier signal de réduction de PAPR comprenant un premier ensemble de PRT qui ne chevauche pas des tonalités de données et la seconde réduction de PAPR comprenant un second ensemble de PRT qui chevauche des tonalités de données et ne chevauche pas des tonalités réservées. Le dispositif de transmission transmet le signal de transmission au dispositif de réception.
