考虑协作开销的同层协作能谱效优化算法

CoMP-based Energy-spectrum-efficiency Optimization Algorithm in Two-layer Cellular Networks

针对由宏蜂窝-毫微蜂窝(Macrocell-Picocell)构成的2层蜂窝网络,对同层CoMP(Coordinated Multipoint)的协作开销问题进行了简要介绍,提出了基于宏基站权值的能谱效优化算法,以减小2层蜂窝网络中因大规模同层CoMP产生的协作开销。对2层蜂窝网络中能谱效随着邻接小区数目、CoMP业务以及迁移功率的变化进行了仿真,仿真结果表明,所提算法能够有效减小协作功耗,提高2层蜂窝网络的能谱效。

The coordination overhead of CoMP(Coordinated Multipoint)in the same layer is briefly introduced,and an energy spectrum efficiency optimization algorithm based on the weight of the macro base station is proposed for a large-scale dense two-layer cellular network composed of macrocells and picocells to reduce the coordination overhead caused by large-scale single-layer CoMP in the two-layer cellular network.The change of the energy spectrum efficiency in a two-layer cellular network is simulated with the number of adjacent cells,CoMP flow and migration power.The results show that the proposed algorithm can effectively reduce the cooperative power consumption and improve the energy spectrum efficiency of the two-layer cellular network.
