Abstract

Des systèmes et des procédés sont divulgués pour rapporter un mesurage d'après des informations de largeur de bande de porteuse concernant une ou plusieurs cellules secondaires. Dans un mode de réalisation, un procédé exécuté par un équipement utilisateur (UE) communiquant avec un nœud maître et un nœud secondaire consiste à recevoir, en provenance du nœud maître, des informations de configuration de mesurage comprenant des informations sur une largeur de bande de porteuse qui est utilisée par une ou plusieurs cellules secondaires, et à effectuer un ou plusieurs mesurages d'après les informations de configuration de mesurage. De cette manière, des mesurages inutiles et un rapport sur des cellules secondaires qui utilisent une largeur de bande qui n'est pas prise en charge par l'UE peuvent être évités.
