ABSTRACT:
Disclosed is a method for controlling transmission power to be allocated to sub-carrier signals in a cellular communication system capable of dividing a frequency band into a plurality of sub-carrier bands and multiplexing the sub-carrier signals of the sub-carrier bands based on multiple frequency reuse factors. The method comprises the steps of determining a target Signal to Interference and Noise Ratio (SINR) of sub-carrier signals employing a first frequency reuse factor selected from the multiple frequency reuse factors; determining a weight of the sub-carrier signals employing the first frequency reuse factor and a weight of other sub-carrier signals employing frequency reuse factors other than the first frequency reuse factor corresponding to the target SINR; and applying the determined weights to the sub-carrier signals employing the first frequency reuse factor and the sub-carrier signals employing frequency reuse factors other than the first frequency reuse factor, thereby controlling the transmission power.
