摘要
针对城市密集城区的信号覆盖存在薄弱、宏站无法完全覆盖、规划建站楼宇业主的强烈反对等主客观原因,致使密集市区的弱覆盖成为运营商一直未解决的难题。为解决末端补盲这一短板,本文提出采用微站对主干道及小区边缘进行灵活协同覆盖方案。实测结果表明:覆盖的道路及小区边缘较以前RSRP、SINR值有明显的提升;同时MR的提取验证了该覆盖区域的弱覆盖比例明显降低。协同覆盖的解决方案对城市密集区域深度补盲具有深远意义。
For the reasons that the signal coverage of the urban residential area is weak, macro eNB does not completely cover the area, and building owners strongly oppose the planning of the building site, the weak coverage has become an unsolved puzzle for operators in densely urban areas. In order to solve the problems, a new solution is proposed, which can cover the roads and resi- dential district edge. Finally, the experiment results show that the coverage rates of roads and residential district edge are higher than those of previous RSRP and S1NR. The proportion of weak coverage is obviously reduced through MR analysis in this region. So, the collaborative solution has great significance to enhance the signal coverage in in densely urban areas.
