摘　　要：通过在无线异构通信场景中对CRE策略进行蒙特卡洛仿真,得到不同场景下针对不同性能指标最优CRE偏置的设置方案,并根据仿真结果,对CRE技术的适用场景及设置策略进行探讨,为异构无线网络实际部署中的优化设计提供理论参考。Based on Monte Carlo simulation of the CRE mechanism in wireless HetNets,optimal CRE biasing strategies for different performance measures are obtained in different scenarios.Based on the simulation results,the application scenarios and the preferred system setting strategies of the CRE technology are discussed.It therefore provides guidelines for the practical deployment and optimization of wireless HetNets from a theoretical perspective.
