Along with the development of TD network equipment, the coverage projects of the different scene are payed more attention. This research is based on the combination of different antenna types and RRUs, we made different solutions to adapt to the wireless environment and reduce the difficulty of the construction, to bring new guide for network supplement and expansion.% 3G移动通信业务正在蓬勃高速发展，常规的网络组网思路已经不能满足实际复杂的无线环境，随着TD-SCDMA网络设备的成熟，针对不同场景的覆盖方案日益被重视；本项目研究思路是基于不同天线类型与不同通道数量的RRU组合，实现多样化天线的设备组网的方案，从而达到适应无线环境与降低施工难度的目的，给日后的网络补盲和扩容带来新的指导思想。
