Abstract

Les modes de réalisation de la présente invention portent sur un procédé et un dispositif de rapport de mesure dans un système d'agrégation de porteuses. Le procédé comprend les opérations suivantes : un équipement utilisateur (UE) reçoit un message provenant d'un côté réseau; conformément au message, l'UE détermine si les porteuses composantes et/ou des cibles de mesure satisfont une condition de déclenchement de rapport de mesure; lorsque le résultat de détermination est oui, l'UE rapporte des informations de mesure d'au moins une porteuse composante et/ou des informations de mesure d'au moins une cible de mesure au côté réseau par un message de rapport de mesure. Dans l'invention, l'UE peut rapporter les informations de mesure de multiples porteuses et/ou points de fréquence ensemble, de façon à simplifier le processus de rapport et à réduire le retard du système, ce qui facilite la mise en œuvre, par le côté réseau, de la gestion de porteuses utilisées par l'équipement utilisateur LTE-A.
