Abstract

La présente invention se rapporte, dans des modes de réalisation, au domaine des communications. La présente invention porte sur un procédé, sur une station de base, sur un équipement utilisateur (UE pour User Equipment) et sur un système permettant d'analyser un rapport de marge de puissance (PHR pour Power Headroom Report) étendu. Le procédé consiste à : recevoir une unité de données de paquet (PDU pour Packet Data Unit) de contrôle d'accès au support (MAC pour Media Access Control) envoyée par un UE, une sous-tête de contrôle MAC de l'unité PDU de contrôle MAC comprenant un bit réservé (R), un bit étendu (E) et un identifiant de canal logique (LCID pour Logic Channel IDentifier); et obtenir l'identifiant LCID dans la sous-tête de contrôle MAC, obtenir un élément de contrôle au support (MCE pour Media Control Element) qui correspond à la sous-tête de contrôle MAC selon l'identifiant LCID, et analyser le PHR étendu dans l'élément MCE. La station de base comprend un module de réception, un module d'obtention et un module d'analyse. L'UE comprend un module de réglage et un module d'envoi. Le système comprend une station de base et un UE. La présente invention peut empêcher un problème de gaspillage des ressources provoqué par le réglage du champ L dans la sous-tête de contrôle MAC; de plus, l'analyse de la correction ne doit pas être déterminée selon le champ L, ce qui réduit la complexité de l'analyse du rapport PHR étendu.
