ABSTRACT:
A received power preset value is varied in such a manner that SIR measured at the base station comes to coincide with the target value SIRt. By varying the received power preset value, a cell zone of the base station varies so that the number of mobile stations connected with the base station increases or decreases thereby SIR at each base station approximating with each other. As a result, deviation of communication quality is restricted so that efficiency of the system can be improved.
