Abstract

In this article, a pilot power based power control (PPBPC) algorithm integrated with base station assignment is proposed, analysed and verified. It is decentralized, uses transmit power control and adapts cell sizes for load distribution. Unlike previously proposed algorithms in the literature, the proposed algorithm does not require prior knowledge of the channel gains between the users and the base stations. Each base station transmits its forward link pilot power inversely proportional to the total reverse link received power. The mobile station senses the strongest pilot power and determines its home base station. The proposed algorithm yields dynamic propagation of base station assignment—which leads to reassignment of home base stations system-wide reducing the total mobile transmit power. We also investigate the system performance various load conditions and show the advantage of load balancing in the cellular system. The simulation study shows that in a load balanced system, the maximum received power at the base stations is minimized which leads to interference balancing of the system.
