Abstract
In a method for deciding an unregistered macrocell user equipment (MUE) adjacent to a femtocell base station (home evolved node B; HeNB), a macrocell base station (macro evolved node B; MeNB) decides occurrence of an unregistered MUE influenced by interference from a HeNB among MUEs. The MeNB requests an adjacent HeNB to transmit system information (SI) of the adjacent HeNB of which interference has influence on the unregistered MUE, and the unregistered MUE searches for the SI of the adjacent HeNB and transmits the searched SI to the MeNB, when it is decided that the unregistered MUE has occurred. The MeNB informs the adjacent HeNB of existence of the unregistered MUE using a closed subscriber group identifier (CSG ID) of the SI of the adjacent HeNB, transmitted from the unregistered MUE.
