Comparison of TD-LTE and FDD LTE technology and annalysis of netw ork integration strategy

为了更好地满足移动用户的海量数据流量业务需求,TD-LTE和FDD LTE融合组网成为全球主流运营商的目标选择。本文从TD-LTE和FDD LTE物理层技术、频谱资源、覆盖性能等方面对比总结了两种制式的差异,并针对TDLTE和FDD LTE融合组网中的关键问题进行了深入分析,最后给出了TD-LTE和FDD LTE融合组网的策略建议,为运营商4G网络的规划和建设提供参考。

In order to meet the needs of massive mobile data, TD-LTE and FDD LTE network integration has become a target selection for global mainstream operators. This paper summarized the differences between the TD-LTE and the FDD LTE from the aspects of physical layer technology, frequency resources, and coverage performance. Then it analyzed key problems in hybrid TDD/FDI） networking. Finally, it gave the proposals in hybrid TDD/FDD networking strategies, and provided reference for operators about 4G network planning and construction.
