Abstract:
In a wireless communication system including a base station capable of transmitting signals on a select number of carriers at a select transmit power per carrier, said base station receiving operating power from a control center located a spaced distance therefrom, a method of automatically controlling the number of carriers utilized by the base station during transmission, said method comprising the steps of:providing operating information associated with the base station, said operating information including a desired number of carriers to be utilized by the base station for transmission, a desired transmit power per carrier, and an actual spaced distance of the base station from the control center;calculating an allowed spaced distance of the base station from the control center from said operating information, said calculated allowed spaced distance being a distance where sufficient operating power reaches the base station to permit the base station to transmit on the desired number of carriers at the desired transmit power per carrier;comparing the actual spaced distance with the calculated allowed spaced distance;activating the desired number of base station carriers at the desired transmit power per carrier if the actual spaced distance is less than, or equal to, the calculated allowed spaced distance; andactivating a reduced number of base station carriers at the desired transmit power per carrier if the actual spaced distance is greater than the calculated allowed spaced distance, said reduced number of base station carriers being less than said desired number of base station carriers.
