摘　　要：作为各大运营商的品牌场景,5G高铁场景覆盖方案成为网络建设的重中之重,以满足高铁用户多样化业务感知需求。从高铁沿线覆盖空洞问题出发,提出波束宽度均衡理论以适配不同站点的连续覆盖需求,同时研究基于8TR的3D智能高铁天线及波束宽度调整方法。采用所提出的创新覆盖方案后,试验线路信号覆盖平均提升3~4d B,近点弱覆盖区域信号覆盖提升5~7 d B,所提出的5G高铁沿线覆盖方案作为一种系统性方案,既可提升高铁线路容量与覆盖,又可解决站点差异性的问题。As the brand scenario of major operators,the scheme on 5 G high-speed railway coverage becomes the top priority of network construction,aiming to meet the diversified service-aware needs of high-speed railway users.According to the problems of coverage holes along the high-speed railway,a beam width equalization theory was put forward to adapt to the continuous coverage requirements between different stations.In addition,a method based on 8 TR 3 D smart highspeed railway antenna and beam width adjustment was proposed.The proposed innovative scheme increases the signal coverage of the test line by 3~4 d B on average,and the signal coverage of the near-point weak coverage area by 5~7 d B.In conclusion,as a systematic solution,the proposed scheme not only enhances the capacity and coverage of high-speed railway lines but also solves the problem of station differences.
