中文摘要：

在由宏小区和家庭小区构成的双层网络中,合理的进行资源分配可有效的控制干扰和优化容量.本文通过建立双层网络的下行干扰模型,分析了不同的资源分配方案和接入机制下的网络性能,提出了接入机制的优化算法,在保证用户通信概率要求的前提下对系统容量进行了优化.仿真结果表明,本文的接入控制机制在保证用户中断概率的条件下,提高了家庭基站允许的最大发射功率,优化了系统容量.

英文摘要：

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 showthat femtocells＇ permitted transmit power is improved based on the proposed access mechanism,and system capacity is also optimized.
