Abstract

Divers aspects de la présente divulgation concernent un UE, un processeur pour une communication sans fil, une entité de réseau et des procédés pour une collecte de données de mesure basée sur une couche supérieure. L'UE reçoit, en provenance d'une entité de réseau, une configuration sur un ou plusieurs ensembles de ressources de signaux de référence périodiques ou semi-persistants pour une collecte de données sur la base d'une signalisation de couche supérieure ; détermine une occupation d'unité de traitement de CSI (CPU) pour les signaux de référence périodiques ou semi-persistants ; effectue une mesure sur des ressources de signal de référence de l'ensemble ou des ensembles de ressources sur la base de l'occupation de CPU déterminée ; et transmet, à l'entité de réseau, des résultats de mesure des ressources de signal de référence de l'ensemble ou des ensembles de ressources par l'intermédiaire de la signalisation de couche supérieure.
