单选题高铁覆盖的优化要点，下面哪一项是错误的？///Which of the following is wrong about the key points of high-speed railway coverage optimization?

A、优先在高铁专项配置单CP的情况下,做好单站点2CP覆盖优化与切换带优化之后,再进行更高级别CP合并.如果直接进行多CP合并,超级小区内部覆盖将很难实施///When a single CP is configured for the high-speed railway project, 2CP coverage optimization and handover area optimization shall be performed for a single site before higher-level CP combination. If multiple CPs are combined directly, it is difficult to implement coverage inside the super cell.

B、通过常规方法调整小区发射功率、小区天线方位角、下倾角,解决小区弱覆盖、越区覆盖等覆盖问题,提升高铁沿线网络覆盖的质量///Adjust the transmit power, antenna azimuth, and downtilt angle of a cell to solve coverage problems such as weak coverage and overshoot coverage, and improve the network coverage quality along a high-speed railway.

C、非必要时不必特意优化CP间的重叠覆盖,提升覆盖质量///Unnecessary optimization of overlapping coverage between CPs to improve coverage quality

D、合理规划PCI,避免出现小区模3干扰,降低干扰,提升业务性能///PCIs should be planned reasonably to avoid cell interference, reduce interference, and improve service performance.

E、优化切换带提升性能,采用超级小区降低切换频次,提升切换性能///Optimize handover areas to improve performance, use super cells to reduce handover frequency, and improve handover performance.
