| 摘 要： | 为了实现对中断小区的自主补偿，该文基于自组织网络(SON)提出功率和倾角联合优化调整的小区中断补偿(COC)机制。首先以天线倾角和发射功率作为优化对象，然后对COC定义了合理的优化目标及评价指标，并对优化模型进行分析，最终给出基于遗传优化算法的补偿机制。在分时长期演进(TD-LTE)场景中进行仿真验证，该机制与参考文献中的3种算法相比，在覆盖、干扰和吞吐量等方面均有明显的改善。

| Abstract: | In order to compensate the outage cell autonomously, this paper derives a solution for Cell Outage Compensation (COC) in Self-Organizing Networks (SON) which is based on the joint adjustment of power and tilt. Firstly, the paper takes the power and tilt as the optimization objects. Then it defines the rational objectives and the evaluation index of the COC, and analyzes the optimization model. Finally, the compensation mechanism based on the Genetic optimization Algorithm (GA) is proposed. The simulation results under the Time Division Long Term Evolution (TD-LTE) scenario show that the proposed solution is better than other three methods in terms of the coverage, interference, and throughput. |
