This contribution deals with the outage probability in a hierarchical macrocell/microcell CDMA cellularsystem.We consider different attenuation models and imperfection of power control with log-normal distribution.Based on IS-95 protocol, the impacts of imperfect sectorization and imperfection of power control on outageProbability are fully investigated From the numerical results, we conclude that the high user capacity may beexpected in the case of relatively tight power control and narrower overlap betWeen sectors and the hierarchicalmacrocell/microcell cellular systems are potential for the future cellular mobile communication.
