【摘要】：超密集組網(wǎng)通過小基站加密部署提升空間復(fù)用的方式,成為解決未來5G網(wǎng)絡(luò)數(shù)據(jù)流量1 000倍以及用戶體驗速率10~100倍提升的有效解決方案。然而,小區(qū)密集部署帶來的干擾問題以及小基站較小的覆蓋范圍導(dǎo)致的高速移動用戶頻繁切換問題,會降低網(wǎng)絡(luò)容量和用戶體驗。因此,為了同時考慮未來5G超密集組網(wǎng)"覆蓋"和"容量"的問題,提出了以控制承載分離以及簇化集中控制為主要技術(shù)特征的5G超密集組網(wǎng)網(wǎng)絡(luò)架構(gòu)。除此之外,針對宏—微和微—微的超密集組網(wǎng)部署場景,給出了具體實現(xiàn)方案。更進(jìn)一步地,針對5G超密集組網(wǎng)網(wǎng)絡(luò)架構(gòu)中可能存在的問題與挑戰(zhàn)進(jìn)行了討論,為后續(xù)研究發(fā)展提供參考。
[Abstract]:The super-dense network is an effective solution for the future 5G network data traffic 1000 times and the user experience rate 10 ~ 100 times increase through the small base station encryption deployment of lifting spatial reuse. However the interference caused by cell intensive deployment and the frequent handoff of high speed mobile users due to the small coverage of small base stations will reduce the network capacity and user experience. Therefore, in order to consider the "coverage" and "capacity" of the future 5G super-dense network at the same time, a 5G super-dense network architecture with the main technical characteristics of control load separation and cluster centralized control is proposed. In addition, the implementation scheme is given for the macro-micro and micro-micro super-dense network deployment scenarios. Furthermore, the possible problems and challenges in the 5G super-dense network architecture are discussed, which provides a reference for further research and development.
