A macro-micro cell structure of wireless communication system for separately processing a forward and a reverse telecommunications in order to increase a reverse link capacity is disclosed. The wireless telecommunication system has a macro cell and at least one micro cell within the macro cell. A micro cell signal processing unit processes a transmission and reception signal of a mobile station located at a service region of the micro cell. A micro cell base station transmits a micro cell forward signal provided from said micro cell signal processing unit to the mobile station to receive a micro cell reverse signal, and receives a macro cell reverse signal of the mobile station which is located at the macro cell and has a short wave path contrast to the macro cell. A macro cell signal processing unit transmits a forward signal to the mobile station through a macro cell antenna and processes the reverse signal provided from said macro cell antenna or said micro cell base station. A transit unit transits the macro cell reverse signal to the macro cell signal processing unit and transiting the signal between the micro cell base station and the micro cell signal processing unit.
