在移动通信站址资源日益稀缺的背景下,LTE网络4扇区部署是一种提高站址利用率、单站覆盖范围的方案。在介绍了LTE网络4扇区部署的基本概念和主要干扰问题的基础上,分别通过理论分析和验证测试论述了4扇区部署对网络质量的影响;并对解决4扇区干扰问题的两种优化技术手段——SFN合并优化技术和RF优化技术分别进行了简要介绍;而后借助现网站点的仿真结果对比了两者的优化增益;最后提出了4扇区建设和优化建议。
As one feasible way to improve cell site occupation ratio and network coverage with the increasingly scarcity of communication cell site resources,4-sector deployment in LTE networks was introduced. The concept of 4-sector deployment and the related interference problem were studied. Both theoretical and field test evaluation performances were shown to indicate the impact of the deployment to networks. To solve the interference problem of 4-sector deployment,two solutions,single-frequency network(SFN)and radio frequency(RF)optimization techniques were proposed and analyzed. The performance gain of these two solutions were compared in existing network scenarios. With all the studies and evaluation,the final advices on 4-sector deployment and optimization were proposed.
