Abstract

Certains modes de réalisation de la présente invention concernent un procédé de communication et un dispositif de réseau. Le procédé consiste à : conformément à des informations de mesure de système rapportées par un équipement d'utilisateur (UE), déterminer une grille virtuelle de l'UE ; et déterminer une fonction de gestion de ressource radio (RRM) de l'UE conformément à la grille virtuelle de l'UE. Les modes de réalisation de la présente invention assurent une commande de fonction de RRM ayant une granularité de grille permettant d'obtenir plus de précision par comparaison avec la fonction de RRM de niveau cellulaire, ce qui permet d'augmenter un taux de réussite de la fonction de RRM de l'UE.
