Abstract:
1. A method for controlling power at a transmitter in a communication system, the method comprising: receiving feedback information from receivers located in the transmitter's own cell; determining data rates of the receivers according to the received feedback information, calculating a load of the cell by calculating an amount of data to be transmitted to the receivers; and calculating transmission power of the transmitter by comparing the load of the cell with a threshold, wherein the threshold is determined by p(t+1)=p(t)P.sub.avg(t)/P.sub.0, where p(t) denotes a price in a previous period, and an initial price p(0) is set by the user or the system according to the communication system and communication environment, and P.sub.avg(t) denotes average transmission power used for data transmission for the previous period, and p(t+1) denotes a price after a predetermined period.
