摘要/Abstract

摘要： 针对飞蜂窝(又叫家庭基站)中干扰严重、资源利用率低等问题，提出一种基于家庭基站密度的自适应无线资源分配策略。通过频率分割抑制宏蜂窝与飞蜂窝间的干扰，依托资源复用和功率控制抑制飞蜂窝之间的干扰，并基于自组织网络技术实现家庭基站接入点(FAP)的自动配置。仿真和性能分析表明，策略在最大限度提高无线资源利用率的同时，基本实现了零干扰，并将系统总吞吐量提高了20%；尤其适用于家庭基站密集或无线资源紧张的应用场合。

Abstract: Serious interference and low radio resource utilization exist in femtocell that is also known as Home Node B (HNB) and Home Enhanced Node B (HeNB). To solve these problems, an adaptive radio resource allocation strategy based on the density of femtocell was proposed. The interference between the macrocell and femtocell was suppressed by frequency division, and interference between the femtocell was also suppressed by the reuse of resources and power control, and the Femtocell Access Point (FAP) was configured automatically based on self-organized network. The simulation and performance analysis show that the proposed strategy can maximize the utilization of radio resource, the interference is close to zero and the overall system throughput is increased by 20%. This strategy is especially suitable for intensive femtocell or occasions with radio resource constraints.

Key words: femtocell, user density, self-organized network, radio resource allocation
