LTE FDD与TD-LTE融合组网在4G特殊场景的覆盖分析

【】：当前,中国移动已建成全球规模最大的TD-LTE网络,网络运营中面临的主要问题是“三高一限”及农村广袤地区等特殊场景的深度覆盖及广覆盖问题。本文在融合组网的大框架下,分析采用LTE FDD技术与TD-LTE协同解决上述问题的可能性。文章首先探讨了中国移动4G现网迫切需要解决的问题,而后分析了LTE FDD的技术特点,及解决上述问题的优势,随后对具体场景的解决方案逐个进行分析。最后是在政策允许时,对下一步测试验证等有关工作的具体建议。

Coverage analysis of LTE fusion network in 4G special scene

: at present, China Mobile has built the largest TD-LTE network in the world. The main problems facing the network operation are the deep coverage and wide coverage of special scenes such as "three high and one limit" and the vast area of rural areas. Based on the framework of converged network, this paper discusses the possibility of using LTE FDD technology to solve the above problems with TD-LTE. This paper first discusses the problems that need to be solved urgently in China Mobile 4G network, and then analyzes the technical features of LTE FDD and the advantages of solving the above problems. Then the solution of specific scene is analyzed one by one. Finally, the specific suggestions for the next step of testing and verification are provided when the policy is permitted.
