Method of operating tdd/virtual fdd hierarchical cellular telecommunication system

The invention proposes a time division duplex / frequency division duplex virtual hierarchical cellular communication system and its operating method. At least a cellular communication system that supports two redundancy scheme proposed in the present invention, mobile stations and; A first redundancy scheme and the mobile station communication, and to define the scope of one of the macrocell, the at least one first type base stations and using; And using the second redundant communication scheme and the mobile stations, and includes defining a range of micro-cell or pico-cell, at least one second type base station which is located inside the boundary of the macro cell. Hierarchical cellular system, frequency division duplex (FDD), time division duplex (TDD), inter-system interference (inter-system interference)
