Patent ID: 7412242

Claim:
A method to control transmission power in a communication system, the method comprising: applying a first weight to sub-carrier signals employing a first frequency reuse factor, thereby controlling the transmission power; and applying a second weight to sub-carrier signals employing a second frequency reuse factor, thereby controlling the transmission power; wherein the first weight and the second weight are determined corresponding to an improvement value of a Signal to Interference and Noise Ratio (SINR) of the sub-carrier signals employing the first frequency reuse factor to increase the SINR of the sub-carrier signals employing the first frequency reuse factor obtained in a previous time duration, and are determined using the improvement value of the SINR, a total transmission power of the communication system, a number of the sub-carriers employing the first frequency reuse factor in the communication system, and a number of the sub-carriers employing the second frequency reuse factor in the communication system.
