TD-LTE高铁覆盖组网方案及关键技术研究

Networking Scheme and Key Technology of TD-LTE High-Speed Railway Coverage

随着现代中国社会经济的高速发展,高速铁路区域已成为用户体验网络质量的重要场景。高速铁路迅猛发展,给人民群众日常出行带来便利的同时,对移动通信网络的覆盖质量也提出了更高要求。怎样建设满足高铁场景下的移动通信网络,成为目前新的问题。从A高铁实际应用出发,通过多RRU共小区等高铁组网关键技术解决A高铁覆盖及容量需求,对类似高铁覆盖场景的建设组网具有一定的指导意义。

With the rapid development of modern Chinese society and economy, high-speed railway area now becomes an important scene for users to experience network quality. The rapid development of high- speed railway puts forward higher requirements for the coverage quality of mobile communication network while bringing convenience to people＇s daily travel. And how to build up a mobile communication network suitable for the high-speed rail scene becomes a new problem at present. From the practical application of high-speed rail, and based on the research of key technology for Muhi RRU common cell, the problem of high-speed railway coverage and capacity requirement is solved, and this is of certain guiding significance for the construction of similar network coverage of high-speed rail scene.
