Abstract

L'invention concerne un procédé et un appareil de gestion d'objet de mesure pour signaux de référence à la demande. Un dispositif sans fil active ou désactive l'objet de mesure de cellule de desserte selon que la SSB pour la cellule de desserte est transmise ou non. Sur la base de l'activation de l'objet de mesure de cellule de desserte, le dispositif sans fil intègre les résultats de mesures basés sur la SSB pour la cellule de desserte dans un rapport de mesure. Sur la base de la désactivation de l'objet de mesure de cellule de desserte : le dispositif sans fil omet de dériver des résultats de mesures basés sur la SSB pour la cellule de desserte.
