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。
通過對中國電信LTE覆蓋高鐵特殊場景的不同頻段組網性能對比，給齣高鐵在郊區採用2.1 GHz主覆蓋，城區段採用1.8和2.1 GHz疊加組網的覆蓋方式的建議，併對疊加組網參數進行特殊設置，做到高鐵用戶和公網用戶的分離，同時在疊加組網基礎上經過超級小區的處理方式進一步提升網絡覆蓋性能。

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 cel network coverage performance is improved by super cel method based on the overlay networking.
