Abstract

L'invention concerne un procédé, un appareil et un système de distribution d'énergie. Le procédé comprend : la réception de premières informations envoyées par un dispositif de réseau, les premières informations étant utilisées pour indiquer le rapport de puissance d'un support principal et/ou d'un support auxiliaire correspondant à un dispositif terminal ; et, selon les premières informations, l'exécution d'une distribution de puissance sur chaque support correspondant. Le procédé selon la présente invention concerne une meilleure solution pour la distribution de l'alimentation entre une cellule principale et une cellule auxiliaire, empêchant ainsi efficacement une baisse des performances de communication due au fait qu'aucune alimentation n'est disponible pour une porteuse auxiliaire.
