Le procédé comprend : une étape d'initialisation permettant, lorsqu'un UE accède initialement à une macro-station de base, de connecter l'UE à une Pcell de sorte qu'un LCH actuel soit géré par la Pcell, la Pcell étant associée à la macro-station de base et fonctionnant sur un support de composant principal ; une étape d'indication permettant d'indiquer à l'UE par un message RRC dédié que le LCH doit être géré par la macro-station de base ou une petite station de base cellulaire, ou doit être géré par la Pcell ou une Scell, la Scell fonctionnant sur un support de composant secondaire.
