Appareil d'un équipement utilisateur (UE) configuré pour : identifier des ressources de chercheur disponibles pour l'UE ; lorsque l'UE comprend une nouvelle porteuse de composante primaire radio (PCC NR), utiliser une première partie des ressources de chercheur pour effectuer des mesures sur la PCC NR ; lorsque l'UE comprend une PSCC NR, utiliser une deuxième partie des ressources de chercheur pour effectuer des mesures sur la PSCC NR ; lorsque l'UE est configuré pour des porteuses composantes secondaires FR2 (SCC) pour une mesure de cellule voisine, utiliser une troisième partie des ressources de chercheur pour effectuer des mesures sur les SCC FR2 et une autre troisième partie pour effectuer des mesures sur toutes les autres SCC NR et les porteuses composantes interfréquences (CC) sans MG ; et utiliser une part égale des ressources de chercheur pour effectuer des mesures sur toutes les autres SCC NR et les CC interfréquences sans MG lorsque l'UE n'est pas configuré avec la PCC NR ou la PSCC NR.
