TD—LTE与TD—SCDMA基站往往是共站址、共天馈系统的，同一套天线参数需要同时满足TD-LTE与TD-SCDMA两张网络的覆盖性能，这无疑给网络优化带来了巨大挑战。主要探讨了在TD—LTE与TD—SCDMA两张网络并存阶段，基于道路扫频并结合自动优化技术实现TD-LTE与TD-SCDMA共天馈小区天线参数联合优化的方法，以确保TD．LTE与TD—SCDMA网络具有较高的覆盖性能。

The base stations of TD-LTE and TD-SCDMA are always co-site and co-antenna system. The same antenna parameters should simultaneously satisfy the coverage performance of both TD-LTE and TD-SCDMA networks. It is a huge challenge for network optimization. In the co-existing period of TD-LTE network and TD-SCDMA networks, a joint antenna parameter optimization method based on road frequency sweep combined with automatic optimization technology in TD-LTE and TD-SCDMA co-antenna area is discussed. The method guarantees high coverage performance of TD-LTE and TD-SCDMA networks.
