[摘要] 文章针对动态业务量,提出了一种动态业务量感知的重配置方案(DTR),在保证系统性能的情况下,最大化系统平均能量效率。DTR根据当前业务量,通过排队论系统预测系统的中断概率,根据一定准则,将系统配置为最大化系统频谱效率(SE)、最大化系统能量效率(EE)或者是混合SE-EE系统。

[Abstract] In this paper, we propose a dynamic traffic-aware reconfiguration (DTR) scheme that can maximize average system energy efficiency (EE) and guarantee system performance. The system can be configured to achieve maximum spectral efficiency (SE), EE, or hybrid SE-EE according to the DTR traffic load. The key criterion for reconfiguring the system is the queuing model.
