SELF-ORGANIZED REUSE PARTITIONING - A DISTRIBUTED DYNAMIC CHANNEL ASSIGNMENT METHOD IN CELLULAR-SYSTEMS

It is known that the spectrum efficiency is improved by the reuse part itioning of a channel. This paper proposes a dynamic channel assignmen t algorithm in which each base station achieves the channel reuse part itioning autonomously while using channels. The principle of the propo sed method is to assign the channel with a larger (or smaller) number to the mobile station closer to the base station. The proposed algorit hm realizes autonomously the channel reuse partitioning in a distribut ed way, without the information exchange among the base stations. The information needed in determining the channel priority is derived by t he base station by learning. The proposed method and other channel ass ignment methods are compared by a computer simulation, and it is shown that the large-capacity, the low interference rate, and the fast chan nel search can simultaneously be achieved.
