Abstract
La présente invention qui appartient au domaine des radiocommunications, concerne un procédé et un dispositif de gestion de la puissance d'émission produite dans un réseau de télécommunications cellulaires. En l'occurrence, l'invention propose une amélioration de la gestion de la puissance d'émission produite grâce à l'adaptation d'un masque de puissance prédéfini à une caractéristique d'émission du signal de l'émission du signal, et à l'application du masque de puissance adapté à une sous-trame ou à un symbole ofdm. La présente invention peut être mise en suvre dans un nsud de réseau tel qu'un nsud enodeb ou un équipement utilisateur.
