Abstract:
A power control method for a radiocommunication system, including the steps of:transmitting signals from a base station to each of a plurality of mobile stations using a respective plurality of transmitting power levels to satisfy predetermined target reception requirements at said respective mobile stations, said plurality of mobile stations forming a set of mobile stations;detecting a change in said set of mobile stations; andin response to said step of detecting, calculating a plurality of power preset adjustment values for application to said respective plurality of transmitting power levels, based on said predetermined target reception requirements which are known in advance of said change in said set of mobile stations, to compensate said plurality of transmitting power levels for said change in said set of mobile stations, wherein said calculating is preemptively performed to reduce disturbances in interference which would be caused by said change based on a predictive assessment of said disturbances in interference, wherein each of said power preset adjustment values is individually provided so that a corresponding mobile station will continue to have its target reception requirements met subsequent to said change in said set of mobile stations.
