Abstract:
A method of enhancing service and service cost in a communication region served by a mobile communication system in which reception during the absence of power fades requires that transmitted power exceed a power threshold P.sub.th, the method comprising the steps of:receiving transmitted signals in said communication region to obtain a signal-fading record;analyzing said signal-fading record to find availability and energy cost for each of a plurality of power-control parameter sets S.sub.i wherein availability is the percentage of transmitting time in which signals are received, energy cost represents the average energy needed to transmit a received bit of information, and an ith power-control parameter set S.sub.i includes a selected static power margin M.sub.i a selected power boost B.sub.i and a selected hold time T.sub.i ;choosing a minimum availability Amin to be provided in said communication region;selecting, from said power-control parameter sets, a selected power-control parameter set that realizes said minimum availability A.sub.min for the lowest energy cost; andsubsequent to said receiving, analyzing, choosing and selecting steps, transmitting communication signals to said communication region with said selected power-control parameter set.
