Abstract :
This paper describes and quantitatively evaluates a new cell design method and new radio link control procedures that increase the capacity of micro-macrocell systems. The cell design method is based on a technique of predicting the location of mobile subscribers in the base station area. The first part of this paper outlines prediction strategies and their precision. The second part describes a new cell selection method intended for use with a micro-macrocell overlay cell layout and shows that this method reduces the base station processing load. This paper also considers channel assignment algorithms and handover algorithms for microcell systems. Specific examples of these approaches are shown for the second-generation Japanese personal digital cellular system
