Abstract

La présente invention permet d'obtenir un rapport de marge de puissance (PHR) correspondant à chaque porteuse de composantes (CC) dans un réseau d'agrégation de porteuses(CA) grâce à un procédé destiné à rapporter une marge de puissance dans un réseau CA. Le procédé comprend l'une quelconque des étapes suivantes : rapporter la marge de puissance correspondant à toutes les CC dans un seul rapport ; rapporter uniquement la marge de puissance correspondant à une porteuse de composantes principale (PCC) dans un seul rapport ; rapporter la marge de puissance correspondant à une porteuse de composantes secondaire (SCC) ou à de multiples SCC parmi au moins une SCC dans un seul rapport ; et rapporter la marge de puissance correspondant à une ou plusieurs CC parmi toutes les CC dans un seul rapport. La présente invention permet de rapporter la marge de puissance correspondant à une ou plusieurs CC, ensemble ou respectivement, résolvant ainsi le problème technique lié à la façon d'obtenir une marge de puissance correspondant aux CC.
