Abstract

Un équipement utilisateur (UE) comprend un émetteur-récepteur, une antenne couplée à l'émetteur-récepteur, et un processeur. Dans un ou plusieurs modes de réalisation, le processeur est configuré pour amener l'UE à recevoir une indication d'une configuration pour un premier ensemble de faisceaux utilisés par un dispositif de réseau pour des mesures de signal de référence, et mesurer les signaux de référence. Un ensemble de données d'apprentissage basé sur les mesures est fourni à un moteur d'apprentissage automatique (interne ou externe à l'UE), qui fournit un modèle d'estimation/prédiction de faisceau (BEP) en réponse. L'UE peut ensuite utiliser le modèle BEP pour déduire ou autrement déterminer une prédiction de faisceau pour le premier ensemble de faisceaux sur la base de mesures d'un second ensemble de faisceaux pour une même configuration indiquée du premier ensemble de faisceaux. Un rapport indiquant la prédiction de faisceau peut ensuite être transmis au réseau.
