【摘要】：当前,无线通信业务朝着高数据率、高动态性方向发展,给传统蜂窝网络带来了极大的挑战。对此,引入小基站(例如:微基站、皮基站)关断机制的异构蜂窝网络是一种有效的解决方案,可以兼顾服务质量和网络能耗。系统进行小基站开关调度须基于小基站与用户通信的信道状态信息,然而,由于关断的小基站处于静默状态,系统无法通过信道估计获得上述信息。为了解决这一问题,该文提出了小基站周期性开启方案。在该方案中,系统周期性地开启小基站,获得用户与小基站通信的信道信息;用户通过宏基站发起接入请求时,系统利用最近一次小基站开启时获得的信道信息进行网络调度决策。周期的设计是影响该方案实施效果的关键性因素,一方面决定了小基站周期性开启需要付出的能量消耗代价,另一方面又决定了信道信息的实时性,从而影响网络调度的效果。该文关注网络的总能耗,将其分为小基站周期性开启消耗的能量和用户服务消耗的能量,并得到了能够实现网络总能耗最小化的周期设计方案。
[Abstract]:At present, the wireless communication business toward high data rate, high dynamic development, has brought great challenges to the traditional cellular network. In this regard, the introduction of a small base station (such as micro base station, scytoblastema station) heterogeneous cellular network switching mechanism is an effective solution, can take into account the quality of service and network energy consumption. The system of small base station switching scheduling to channel state information, small base station and user communication based on however, due to the small base station off in a quiet state, the system cannot obtain the information through channel estimation. In order to solve this problem, this paper put forward the scheme to open the small base station periodically. In this scheme, the periodic system open a small base station, channel information users and small base station communication; users through the Acer station initiates an access request, the system obtained by a recent small base station open channel information network scheduling The design cycle. Decision making is a key factor affecting the effect of the implementation of the scheme, a small base station determines the periodic opening needs to be paid to the energy consumption cost, on the other hand, determines the real-time channel information, thus affecting the network scheduling effect. This paper focuses on total energy consumption of the network, which will be divided into small the base station periodically open the energy consumption and service consumption of energy, and obtained the design cycle to achieve the total energy consumption of the network is minimized.

【正文快照】： 欧盟研究显示,在现有能源使用模式下,信息通信行业能耗正以每10年翻一番的速度增长,其中蜂窝网络能耗增长最为迅速[1]。而在蜂窝网络能耗中,基站消耗了总能量的60%—80%[2]。因此,基站能耗控制是需要迫切解决的问题。无线通信业务量的急剧增加是促使基站能耗快速增长的主要因
