Abstract

Des modes de réalisation de la technologie de l'invention concernent un cadre et des procédures de collecte de données par le réseau pour entraîner des modèles d'apprentissage automatique qui peuvent être utilisés pour une gestion de faisceau basée sur AA, une amélioration de rétroaction d'informations d'état de canal (CSI) basée sur AA, et analogues. Un procédé donné à titre d'exemple consiste à transmettre, par un nœud de réseau à un dispositif sans fil, un message de configuration pour configurer une ou plusieurs opérations de journalisation de mesure, et à recevoir, de la part du dispositif sans fil, un message de rapport de journal associé à un résultat d'au moins une opération de journalisation de mesure desdites une ou plusieurs opérations de journalisation de mesure. Dans ce procédé donné à titre d'exemple, une réception du message de configuration permet au dispositif sans fil de journaliser un ou plusieurs résultats de mesure à l'aide desdites une ou plusieurs opérations de journalisation de mesure.
