摘　　要：城市轨道交通车地综合通信系统(LTE-M)在枢纽换乘站存在同频干扰问题,需研究干扰源头——枢纽换乘站基站的频率配置方案。以昆明轨道交通4号线和5号线枢纽换乘站火车北站两线LTE-M系统频段规划方案为例,基于LTE-M系统承载业务需求和频段使用实际情况,分析了枢纽换乘站LTE-M系统基站的不同频段异频和同频段异频2种规划方案,以及同频段的全部同频、部分同频和无线网络共享3种规划方案,并比较了各种规划方案的优缺点,提出了各种规划方案的适用性建议。Co-frequency interference problem exists in urban rail transit hub interchange station LTE-M(long term evolution-metro)system.The interference source—frequency configuration scheme of hub interchange station base station should be studied.Taking the LTE-M system frequency band planning scheme of Kunming Rail Transit Line 4 and Line 5 hub interchange station Kunming North Railway Station as example,based on the service requirements and actual use of LTE-M system frequency band,two planning schemes of different frequencies in different frequency bands and in the same bands of the LTE-M system are analyzed.For three planning schemes of co-frequency,partial co-frequency and wireless network sharing in the same frequency band,their advantages and disadvantages are compared,and the applicability suggestions of each planning scheme are proposed.
