摘要:
为了解决18 GB专用频段对城市轨道交通两线换乘区域的LTE(长期演进)干扰问题，以福州轨道交通4号线GOA4(无人干预列车运行)级FAO(全自动运行)线路与5号线GOA2(半自动化列车运行)级线路的换乘站（浦口站）为例，通过TD(时分)LTE技术分析与实地测试，对两线换乘区域的LTE抗干扰设计与18 GB频段规划进行了深入研究，形成了4号线、5号线换乘区域LTE抗干扰解决方案，为福州后续城市轨道交通线路类似问题的解决提供参考。
Abstracts:
To solve the LTE (long-term evolution) interference problem in the two-line interchange area of urban rail transit with 1.8 GB dedicated frequency band, the interchange station (Pukou Station) of Fuzhou Rail Transit Line 4 GOA4 (unattended train operation) grade FAO (fully automatic operation) line and Fuzhou Rail Transit Line 5 GOA2 (semi-automatic train operation) grade FAO line is taken as an example, and the LTE anti-interference design and 1.8 GB frequency band planning of the two-line interchange area are studied in depth through the analysis and field test of TD (time division)-LTE technology. The LTE anti-interference solution of the interchange area of Line 4 and Line 5 is formed, providing a reference for the solution of similar problems of the subsequent rail transit lines in Fuzhou.
