摘要
分层异构密集无线网络节点部署更加密集,对系统模型和场景部署都有了新的要求。与之前的分层异构网络相比,大规模小小区的部署不仅使异构节点的干扰环境更加复杂,能量消耗也更大。针对小小区增强技术的系统模型和部署场景,从系统级的角度对分层异构密集无线网络的能效性能进行了分析,并仿真了不同pico数目对系统能效性能的影响。这些性能分析对以后分层异构密集无线网络中能效的优化以及研究具有指导意义。
In dense heterogeneous wireless network, the large-scale small cell deployment can substantially increase not only the complexity of the interference environment but also the network energy consumption. Based on the system model and deployment scenario of small cell enhancement, the energy efficiency in dense heterogeneous wireless network was analyzed and simulated from the sight of system level under different scenarios with different pico numbers. The evaluation has profound guiding significance for the future energy efficiency analysis and optimization in dense heterogeneous wireless network.
