A method for controlling transmission power to be allocated to sub-carrier signals in a cellular communication system, the method comprising the steps of: determining an improvement value S [dB] being the amount of improvement of a signal to interference and noise ratio, SINR, of sub-carrier signals X R1,..., X N'-1 employing a first frequency reuse factor K selected from multiple frequency reuse factors, wherein K is greater than 1, K>1; determining a first weight W K of the sub-carrier signals X R1,..., X N'-1 employing the first frequency reuse factor and a second weight W 1 of other sub-carrier signals X 0,..., X R1-1 employing a frequency reuse factor of 1 other than the first frequency reuse factor; and controlling the transmission power by applying the first weight W K to the sub-carrier signals X R1,..., X N'-1 and applying the second weight W 1 to the other sub-carrier signals X 0,..., X R1-1, wherein the cellular communication system is capable of dividing a frequency band into a plurality of sub-carrier bands and multiplexing the sub-carrier signals X 0,..., X R1-1...,X R1,..., X N'-1 of the plurality of sub-carrier bands based on the multiple frequency reuse factors, wherein the first weight W K improves the SINR of each of the subcarrier signals X R1,..., X N'-1 by S[dB] and wherein a relation between the first weight W K and the second weight is determined based on a total transmission power P of the cellular communication system, wherein P is equal to a sum of a first multiplication and a second multiplication, the first multiplication is determined by multiplying a square of the second weight W 1 by a number R1 of the sub-carrier signals X 0,..., X R1-1 employing the frequency reuse factor of 1, and the second multiplication is determined by multiplying a square of the first weight W K by a number RK of the sub-carrier signals X R1,..., X N'-1 employing the first frequency reuse factor, wherein RK=N'-R1. determining an improvement value S [dB] being the amount of improvement of a signal to interference and noise ratio, SINR, of sub-carrier signals X R1,..., X N'-1 employing a first frequency reuse factor K selected from multiple frequency reuse factors, wherein K is greater than 1, K>1; determining a first weight W K of the sub-carrier signals X R1,..., X N'-1 employing the first frequency reuse factor and a second weight W 1 of other sub-carrier signals X 0,..., X R1-1 employing a frequency reuse factor of 1 other than the first frequency reuse factor; and controlling the transmission power by applying the first weight W K to the sub-carrier signals X R1,..., X N'-1 and applying the second weight W 1 to the other sub-carrier signals X 0,..., X R1-1, wherein the cellular communication system is capable of dividing a frequency band into a plurality of sub-carrier bands and multiplexing the sub-carrier signals X 0,..., X R1-1...,X R1,..., X N'-1 of the plurality of sub-carrier bands based on the multiple frequency reuse factors, wherein the first weight W K improves the SINR of each of the subcarrier signals X R1,..., X N'-1 by S[dB] and wherein a relation between the first weight W K and the second weight is determined based on a total transmission power P of the cellular communication system, wherein P is equal to a sum of a first multiplication and a second multiplication, the first multiplication is determined by multiplying a square of the second weight W 1 by a number R1 of the sub-carrier signals X 0,..., X R1-1 employing the frequency reuse factor of 1, and the second multiplication is determined by multiplying a square of the first weight W K by a number RK of the sub-carrier signals X R1,..., X N'-1 employing the first frequency reuse factor, wherein RK=N'-R1.
