FEMTO CELL INTERFERENCE CONTROL METHOD CONSIDERING OF A MACRO CELL CAPABLE OF CONTROLLING INTERFERENCE IN A FEMTO CELL

摘要

PURPOSE: A femto cell interference control method considering of a macro cell is provided to avoid interference for the macro cell by preventing the interference of a femto cell for the macro cell.;CONSTITUTION: The reception power of a macro cell base station is measured or estimated(S110). A linear coefficient is multiplied at the transmission power of the macro cell base station(S120). In case the reception power is zero, the transmission power minimum values of a femto cell is added to multiplication result values(S130). Minimum values are acquired from addition result values and the maximum transmission power values of the femto cell. The minimum value and the minimum transmission power values of the femto cell are established as the transmission power of the femto cell(S140).;COPYRIGHT KIPO 2012
