【摘要】：在控制覆蓋和業(yè)務(wù)覆蓋分離的超蜂窩網(wǎng)絡(luò)架構(gòu)下,負(fù)責(zé)數(shù)據(jù)傳輸?shù)臉I(yè)務(wù)基站可根據(jù)業(yè)務(wù)量的動(dòng)態(tài)變化靈活休眠或喚醒,或?qū)I(yè)務(wù)轉(zhuǎn)移到相鄰業(yè)務(wù)基站或上層控制基站,以有效降低網(wǎng)絡(luò)能耗.而如何優(yōu)化超蜂窩網(wǎng)絡(luò)部署,并根據(jù)用戶服務(wù)質(zhì)量要求和網(wǎng)絡(luò)業(yè)務(wù)量變化動(dòng)態(tài)調(diào)整業(yè)務(wù)基站部署密度、休眠方式及無(wú)線資源分配,是超蜂窩網(wǎng)絡(luò)中十分重要且具有挑戰(zhàn)性的問題.本文總結(jié)了該領(lǐng)域的一系列研究成果:在高能效網(wǎng)絡(luò)部署方面,面向控制基站和業(yè)務(wù)基站功能及拓?fù)浣Y(jié)構(gòu)的差異性采用不同的網(wǎng)絡(luò)模型進(jìn)行分析,基于隨機(jī)幾何理論分析給出了業(yè)務(wù)基站和控制基站的最優(yōu)部署密度;在高能效基站動(dòng)態(tài)控制方面,提出了基于負(fù)載轉(zhuǎn)移的高能效動(dòng)態(tài)基站休眠和頻譜資源分配機(jī)制,可在保證網(wǎng)絡(luò)覆蓋及用戶服務(wù)質(zhì)量的前提下有效降低網(wǎng)絡(luò)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.
