Abstract

La présente invention concerne un appareil d'un équipement d'utilisateur (UE pour User Equipment). L'appareil peut comprendre un premier ensemble de circuits et un second ensemble de circuits. Le premier ensemble de circuits peut être utilisé pour traiter un message de commande de ressource radio (RRC pour Radio Resource Control) provenant de la première porteuse de l'Internet des objets à bande étroite (NB-IoT pour Narrow Band Internet-of-Things) dirigeant l'équipement utilisateur pour traiter un message d'informations système (SI pour System Information) provenant de la seconde porteuse de l'Internet NB-IoT. Le second ensemble de circuits peut être utilisé pour déterminer un ou plusieurs paramètres de la seconde porteuse de l'Internet NB-IoT sur la base du message de commande RRC. Le ou les paramètres peuvent comprendre : un nombre de répétitions pour le message d'informations SI provenant de la seconde porteuse de l'Internet NB-IoT et/ou un numéro de trame radio de départ (SRFN pour Starting Radio Frame Number) pour le message d'informations SI provenant de la seconde porteuse de l'Internet NB-IoT.
