【摘要】：现有的基站休眠节能策略面临如何在提高能效的同时保证业务QoS的问题,提出了一种在密集场景下微基站与宏基站协作的微基站休眠策略,以提高系统能效。首先,微基站在业务请求较低时进入休眠状态以达到节能的目的;其次,利用宏基站覆盖范围广的特点,将其作为协作基站,当微基站休眠时它能够辅助处理一些业务;最后,将业务按照容量大小分类,发挥出宏基站与微基站的各自特点,有区别地选择基站处理业务。仿真结果表明,该方案比现有的基站休眠节能方案具有优势。
[Abstract]:In order to improve system energy efficiency, the existing base station sleep saving strategy is faced with the problem of how to improve energy efficiency while ensuring service QoS. In order to improve system energy efficiency, this paper proposes a microbase station dormancy strategy for cooperation between microbase station and macro base station in dense scenarios. Firstly, the microbase station enters into the dormant state when the service request is low to achieve the purpose of saving energy; secondly, the microbase station can be used as the cooperative base station to deal with some services when it is dormant by taking advantage of the broad coverage of the macro base station. Finally, the service is classified according to the capacity, giving play to the respective characteristics of the macro base station and the micro base station, and selecting the base station to deal with the service differently. The simulation results show that the proposed scheme is superior to the existing base station dormancy energy saving scheme.
