【摘要】：在控制覆盖和业务覆盖分离的超蜂窝网络架构下,负责数据传输的业务基站可根据业务量的动态变化灵活休眠或唤醒,或将业务转移到相邻业务基站或上层控制基站,以有效降低网络能耗.而如何优化超蜂窝网络部署,并根据用户服务质量要求和网络业务量变化动态调整业务基站部署密度、休眠方式及无线资源分配,是超蜂窝网络中十分重要且具有挑战性的问题.本文总结了该领域的一系列研究成果:在高能效网络部署方面,面向控制基站和业务基站功能及拓扑结构的差异性采用不同的网络模型进行分析,基于随机几何理论分析给出了业务基站和控制基站的最优部署密度;在高能效基站动态控制方面,提出了基于负载转移的高能效动态基站休眠和频谱资源分配机制,可在保证网络覆盖及用户服务质量的前提下有效降低网络能耗.
[Abstract]:Under the supercellular network architecture of control coverage and business coverage separation, the service base station responsible for data transmission can be flexible or awaken according to the dynamic changes in traffic volume, or transfer services to adjacent business base stations or upper control base stations to effectively reduce network energy consumption, and how to optimize the deployment of supercellular network and service according to user service The dynamic adjustment of service base station deployment density, dormancy mode and wireless resource allocation is a very important and challenging problem in the hyper cellular network. This paper summarizes a series of research results in this field: the function and topology of the control base station and the service base station in the high efficiency network deployment. The difference of structure is analyzed by different network models, the optimal deployment density of business base station and control base station is given based on random geometric theory. In the dynamic control of high energy efficiency base station, the mechanism of high energy efficiency dynamic base station dormancy and spectrum resource allocation based on load transfer is proposed, which can guarantee network coverage and users. On the premise of the quality of service, the energy consumption of the network is effectively reduced.
