Abstract

La présente invention concerne un procédé et un système de communication permettant de faire converger un système de communication de 5e génération (5G), destiné à prendre en charge des débits de données supérieurs à ceux d'un système de 4e génération (4G) avec une technologie dédiée à l'Internet des objets (IoT). La présente invention peut être appliquée à des services intelligents basés sur la technologie de communication 5G et sur la technologie associée à l'IoT, tels qu'une maison intelligente, un bâtiment intelligent, une ville intelligente, une voiture intelligente, une voiture connectée, des soins de santé, l'enseignement numérique, le commerce de détail intelligent, et des services de sécurité et de sûreté. La présente invention concerne un procédé de sélection d'une source de référence de synchronisation pour une communication de liaison latérale à porteuses multiples, consistant à : sélectionner une source de référence de synchronisation en fonction d'un état d'un UE sur de multiples porteuses ; et utiliser la source de référence de synchronisation sélectionnée en tant que source de référence de synchronisation pour l'UE sur toutes les porteuses.
