Abstract

La présente invention concerne un procédé, un dispositif et un système de traitement de rapport de marge de puissance, et le procédé de traitement de rapport de marge de puissance comprend les étapes suivantes : un équipement utilisateur détermine des premières informations de marge de puissance correspondant à une première sous-trame dans une première cellule (101), la première cellule appartenant à un premier groupe d'avance temporelle (TAG), et le premier TAG étant un TAG dans un premier nœud B évolué (eNB) ou un premier groupe de cellules ; en fonction de la première sous-trame, détermine une deuxième sous-trame ayant une période de chevauchement avec la première sous-trame dans une deuxième cellule (102), la seconde cellule appartenant à un deuxième TAG, et le deuxième TAG étant un TAG dans un deuxième eNB ou un deuxième groupe de cellules ; détermine si la période de chevauchement entre la première sous-trame et la deuxième sous-trame est supérieure ou supérieure ou égale à un seuil de période prédéfini (103) ; si tel est le cas, détermine des deuxièmes informations de marge de puissance correspondant à la deuxième sous-trame dans la deuxième cellule (104) ; envoie les premières informations de marge de puissance et les deuxième informations de marge de puissance à au moins un eNB parmi le premier eNB et le deuxième eNB ou à au moins un groupe de cellules parmi le premier groupe de cellules et le deuxième groupe de cellules (105). En fonction des premières informations de marge de puissance et des deuxièmes informations de marge de puissance rapportées par l'équipement utilisateur, l'eNB ou le groupe de cellules peuvent déterminer correctement l'état de consommation d'énergie de l'équipement utilisateur pendant la transmission en liaison montante sur les deux eNB ou groupes de cellules.
