TD-LTE网络一般采用同频组网，同频干扰严重，良好的覆盖和干扰控制对网络性能意义重大，所以在网络规划和优化中需要重点考虑重叠覆盖。在对不同组网方式差异和重叠覆盖多原因分析的基础上，提出了重叠覆盖评估方法，在TD-LTE网络规划和优化阶段提出控制重叠覆盖的策略，根据TD-LTE试验网的实际工作，由实例验证了针对重叠覆盖调整的方法和策略。
TD-LTE網絡一般採用同頻組網，同頻榦擾嚴重，良好的覆蓋和榦擾控製對網絡性能意義重大，所以在網絡規劃和優化中需要重點攷慮重疊覆蓋。在對不同組網方式差異和重疊覆蓋多原因分析的基礎上，提齣瞭重疊覆蓋評估方法，在TD-LTE網絡規劃和優化階段提齣控製重疊覆蓋的策略，根據TD-LTE試驗網的實際工作，由實例驗證瞭針對重疊覆蓋調整的方法和策略。

The TD-LTE network generally applies the same frequency networking, but it has serious co-frequency interferences. The good coverage and interference control are very significant to the performance of network. Therefore, the overlapping coverage should be mainly considered in network planning and optimization. Based on analysis of the differences between different networking modes and the reasons of overlapping coverage, the assessment methods of overlapping coverage are proposed. Then the strategies for controlling overlapping coverage are proposed in the phases of TD-LTE network planning and optimization. The adjustment methods and strategies for overlapping coverage are verified by examples based on the actual work of TD-LTE trial network.
