Analysis of optimum resource management strategies in layered cellular structures

The paper deals with the identification of channel allotment criteria in a multilayered cellular environment composed by a regular grid of macrocells, plus a number of microcells deployed in the most congested areas. The optimum resource allotment between microcells and macrocells cannot be simply worked out by considering the expected traffic densities for each cell type, but it has to take into account their different functionalities, After a quick overview of the main working principles of such a multilayered architecture, the paper introduces some basic planning criteria. The analysis is carried out considering realistic traffic statistics and different propagation models for macrocells and microcells have been adopted
