【摘要】：現(xiàn)有的基站休眠節(jié)能策略面臨如何在提高能效的同時(shí)保證業(yè)務(wù)QoS的問題,提出了一種在密集場(chǎng)景下微基站與宏基站協(xié)作的微基站休眠策略,以提高系統(tǒng)能效。首先,微基站在業(yè)務(wù)請(qǐng)求較低時(shí)進(jìn)入休眠狀態(tài)以達(dá)到節(jié)能的目的;其次,利用宏基站覆蓋范圍廣的特點(diǎn),將其作為協(xié)作基站,當(dāng)微基站休眠時(shí)它能夠輔助處理一些業(yè)務(wù);最后,將業(yè)務(wù)按照容量大小分類,發(fā)揮出宏基站與微基站的各自特點(diǎn),有區(qū)別地選擇基站處理業(yè)務(wù)。仿真結(jié)果表明,該方案比現(xiàn)有的基站休眠節(jié)能方案具有優(yōu)勢(shì)。
[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.
