Abstract

Des exemples de la divulgation concernent l'augmentation de l'efficacité de signalisation dans des réseaux à l'aide de modèles d'intelligence artificielle/apprentissage machine (IA/ML) pour générer des prédictions de trafic de réseau. Dans des exemples de la divulgation, un UE reçoit, en provenance d'un nœud de réseau, des informations de configuration relatives à une prédiction de trafic de réseau. Les informations de configuration indiquent des critères permettant de sauter la surveillance d'un canal de physique de contrôle descendant (PDCCH). L'UE reçoit des informations de motif de données de liaison descendante en provenance du nœud de réseau et détermine sur la base, au moins en partie, des informations de motif de données de liaison descendante reçues si un critère indiqué à partir des informations de configuration est satisfait, et commande la surveillance de saut du canal de physique de contrôle descendant (PDCCH) conformément aux critères indiqués.
