Abstract
A method and system adapt scheduling priorities in a wireless communications system to conserve battery power in mobile stations operating within the system. A base station, within the system, receives battery power level information and other setup information from mobile stations operating within the service area of the base station during call setup procedures. Based on the battery power level information and other setup information, the base station assigns frequency channels to the mobile stations so that those mobile stations having battery power levels below a threshold value are assigned frequency channels that have lower interference levels than frequency channels assigned to other mobile stations. The frequency channel assignments are transmitted to the mobile stations.
