Abstract

La présente invention concerne un procédé dans un équipement utilisateur (UE), comprenant les étapes consistant : à recevoir un bloc d'informations maître à bande étroite (MIB-NB) depuis une station de base ; conformément à des informations de mode de fonctionnement indiquées dans le MIB-NB, à obtenir des informations de configuration associées à un bloc d'informations système de type 1 (SIB1-BR) d'un UE présentant une largeur de bande réduite, une faible complexité ou une couverture augmentée, au moyen d'au moins une des opérations suivantes : extraction d'au moins une partie des informations de configuration à partir du MIB-NB ; et réception de ladite partie des informations de configuration en provenance de la station de base par l'intermédiaire d'une signalisation RRC de commande de ressources radio ; et à acquérir le SIB1-BR sur la base des informations de configuration.
