    摘要： A technology that can adaptively control an access mode according to a shared band or an unlicensed band used by an adjacent communication system. An access mode controlling apparatus includes a band recognition unit to recognize a usage rate of an unlicensed band or a shared band that is used by an adjacent communication system of a target communication system; a mode determination unit to determine, as an access mode, any one of a contention access mode and a contention-free access mode, based on the usage rate of the unlicensed band or the shared band; and an information transmitter to transmit mode information associated with the determined access mode to member nodes or a base station of the target communication system.

    摘要： A communication method of a macro base station including reporting information about a broadcast channel section in order to identify a femtocell in a macrocell of the macro base station set in a downlink broadcast channel of the macrocell, is provided. The macro base station receives position information of a mobile terminal and a request for information about neighboring femto base stations from the mobile terminal, when the mobile terminal identifies an accessible femto base station among the at least one femto base station in the broadcast channel section. The macro base station generates a list of the neighboring femto base stations of the mobile terminal and information about the neighboring femto base stations based on the position information of the mobile terminal, and transmits the list of the neighboring femto base stations and the information about the neighboring femto base stations to the mobile terminal.
