Abstract

La présente invention concerne un procédé, un appareil et un système permettant de signaler des informations de capacités d'équipement d'utilisateur. Le procédé consiste à : recevoir un message d'interrogation de capacités d'UE envoyé par une station de base, le message d'interrogation de capacités d'UE comprenant des informations de demande de signalement de capacités d'UE ; et signaler des informations de capacités d'UE en fonction des informations de demande de signalement de capacités d'UE dans le message d'interrogation de capacités d'UE. Dans certains modes de réalisation de la présente invention, des informations de capacités d'UE sont sélectivement transmises selon une demande d'une station de base, ce qui permet d'économiser des champs de signalement de capacités d'UE, de surmonter une redondance d'informations, et d'améliorer le taux d'utilisation de ressources d'interface radio.
