Abstract

In the two-layer network comprised of macro cells and femtocells

reasonable allocation of resources can effectively control interference and optimize capacity.In this paper

network performance when using different resource allocation schemes are analyzed with the model of downlink interference in two-layernetwork.The optimization algorithm for users is proposed

which can increase system capacity and guarantee users' communication probability.The simulation results show that femtocells' permitted transmit power is improved based on the proposed access mechanism

and system capacity is also optimized.
