摘　　要：根据高速铁路覆盖的特点,建议WCDMA高铁覆盖初期采用公网方式,按AMR12.2kbit/s做连续覆盖。通过链路预算分析,以及多条高铁线路的实测结果,给出了基站站间距取值建议,最后列出了改善高铁覆盖、减少切换的技术措施。According to the characteristics of high-speed railway coverage,it gives the suggestions that the WCDMA coverage for high-speed railway should be planned to realize seamless coverage of AMR 12.2 kbit/s service at the base of the existed network.It gives the reference distance between adjacent base stations according to the analysis of link budget and the test results of several high-speed railways.Finally it introduces the techniques to reduce the handover frequency and improve the quality of high-speed railway coverage.
