Abstract
Selon divers modes de réalisation, la présente invention concerne des techniques relatives à un RIC (contrôleur intelligent de RAN (réseau d'accès radio)), à un nœud RAN et/ou à un équipement utilisateur (UE). Le RIC peut être configuré pour déterminer d'ajouter, de modifier ou de supprimer une configuration de formation de faisceau pour un ou plusieurs équipements utilisateur (UE), la configuration de formation de faisceau étant associée à un mode de formation de faisceau sans grille de faisceaux (non-GoB). Le RIC peut en outre être configuré pour coder, sur la base de la détermination, un message destiné à être transmis au nœud RAN pour ajouter, modifier ou supprimer la configuration de formation de faisceau pour l'UE. Le nœud RAN peut être configuré pour ajouter, modifier ou supprimer en conséquence la configuration de formation de faisceau. D'autres modes de réalisation peuvent être décrits et/ou revendiqués.
