DYNAMIC FREQUENCY SELECTING METHOD IN FUTURE WIRELESS COMMUNICATION SYSTEM BASED THE THE ADAPTIVE ANTENNA

摘要

PURPOSE: A dynamic frequency selecting method in adaptive antenna based next generation mobile communication system is provided to select the FA(Frequency Assignment) of a pico base station depending on the peripheral interference when a macro base station and plural pico base stations exist hierarchically. CONSTITUTION: A pico base station detects the location of interference nodes by using an adaptive antenna(S61), and rotates and transmits a beam to which a beam number for each rotation angle is assigned(S62). The pico base station detects the positions of service target terminals(S64). The pico base station calculates the amount of interference caused by the interference nodes for each service target terminal(S65). The pico base station selects the FA of which interference amount for each service target terminal is minimized(S66).
