摘要
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。
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.
