摘要
针对传统无线局域网方案存在的问题,结合TD-LTE技术特点,分析了城市轨道交通车地无线通信业务需求,并提出基于TD-LTE技术综合承载信号CBTC系统、PIS、车载CCTV等系统的车地无线通信综合承载方案,并重点介绍TD-LTE系统构成、网络资源分配、信号覆盖方案以及抗干扰对策等,为城市轨道交通车地无线通信综合承载设计提供参考。
In view of the problems existing in the traditional WLAN solutions,combined with the characteristics of TD-LTE technology,the requirements of urban rail transit for train-ground wireless communication are analyzed,and a TD-LTE-based trainground wireless communication integrated bearer solution is proposed,carrying CBTC system,PIS,and on-board CCTV system.It focuses on the introduction of the TD-LTE system composition,network resource allocation,signal coverage scheme,and anti-interference countermeasures,etc.,and provides a reference for the design of train-ground integrated wireless bearer for urban rail transit.
