摘要
多普勒频移大小区重选、切换频繁以及穿透损耗大,是高铁覆盖优化的难题。因此,从LTE高铁覆盖的关键技术和优化体系两个方面进行LTE高铁优化,以全面优化高铁网络覆盖能力,提升网络性能和用户感知。
Large Doppler frequency shifts,frequent cell reselections,handovers,and large penetration loss are the main challenges for high-speed rail coverage optimization.This article analyzes the optimization of LTE high-speed rail from two aspects:the key technologies and optimization system of LTE high-speed rail coverage,to fully optimize the high-speed rail network coverage capability,and improve network performance and user perception.
