摘要
通过对中国电信LTE覆盖高铁特殊场景的不同频段组网性能对比,给出高铁在郊区采用2.1 GHz主覆盖,城区段采用1.8和2.1 GHz叠加组网的覆盖方式的建议,并对叠加组网参数进行特殊设置,做到高铁用户和公网用户的分离,同时在叠加组网基础上经过超级小区的处理方式进一步提升网络覆盖性能。
It first compares the different frequency band networking performance of the special scene of China Telecom LTE coverage high railway. Based on the above, it gives the suggestions that 2.1 GHz is used in suburb area and the overlay networking of 1.8 GHz and 2.1 GHz is used in urban area. It makes special setting on overlay networking parameter to divide the high-speed railway user and public network user. Meanwhile, the cell network coverage performance is improved by super cell method based on the overlay networking.
