摘要:

提出了一种简化限制条件的5G高铁站间距计算方法,从5G特征入手,考虑多种设备形态下5G高铁覆盖情况,并结合高铁场景特定的限制条件,将复杂的限制条件简化为单一限制条件,平衡了理论研究和实际使用间的差距。从射频的角度,分析不同的大规模MIMO设备形态对5G高铁覆盖的影响;分析不同场景对5G高铁覆盖的影响;分析5G高铁站间距的影响因素,并通过计算入射角、下倾角与站高、站轨距、覆盖距离的关系,获取简单的站间距计算式;分析可用站高、站轨距与覆盖距离的相关性,简化限制条件为单一参数——覆盖距离。提出的方法适用于已知站轨距、站高、站型和部署场景的单一站点的站间距评估。通过对比验证,使用所提方法评估的站间距具备极高的准确性,计算误差仅为3 m,准确率为99.14%。

Abstract:

A method of 5G cell station spacing for high-speed railways with simplified restriction conditions was presented that balance the gap between theoretical research and practical use.To begin, the influencing factors of 5G cell station spacing for high-speed railways were analyzed, such as incident angle, downtilt angle, station height, station gauge distance and coverage distance.Then, a simple station spacing calculation method was obtained with the restriction conditions simplified to a single parameter (coverage distance) by analyzing the correlation between available station height, gauge and coverage distance.Comparison and verification show that the cell station spacing calculation done with the proposed method has high accuracy, with a calculation error of only 3 m and an accuracy of 99.14%.

Key words: 5G, high-speed railway communication, simplified restriction condition, coverage distance
