【摘要】：超密集無(wú)線異構(gòu)網(wǎng)絡(luò)被公認(rèn)為是大幅提升無(wú)線網(wǎng)絡(luò)容量、解決蜂窩網(wǎng)所面臨的1 000倍數(shù)據(jù)量挑戰(zhàn)最富有前景的一種5G組網(wǎng)技術(shù)。但是,與5G愿景背道而馳的是網(wǎng)絡(luò)的超密集化部署在提升譜效的同時(shí)也極度地增大了系統(tǒng)的能耗,降低了通信能效。旨在利用超密集異構(gòu)網(wǎng)絡(luò)具有的全網(wǎng)管理能力和網(wǎng)絡(luò)分集效應(yīng),從宏觀的網(wǎng)絡(luò)匹配與微觀的資源聚合兩方面探索超密集異構(gòu)網(wǎng)絡(luò)綠色演進(jìn)的關(guān)鍵理論與技術(shù)。首先論述了綠色演進(jìn)的基本理念,然后提出了利用負(fù)載自適應(yīng)的基站開關(guān)控制、主動(dòng)緩存和干擾感知的跨網(wǎng)資源分配三大關(guān)鍵技術(shù)來(lái)提升網(wǎng)絡(luò)的能效,同時(shí)也討論了每種技術(shù)在應(yīng)用時(shí)所面臨的挑戰(zhàn)。
[Abstract]:Ultra-dense wireless heterogeneous networks are widely recognized as a 5G networking technology that can greatly enhance the capacity of wireless networks and solve the challenge of 1,000 times the amount of data faced by cellular networks. However, contrary to the 5G vision, the super-dense deployment of the network not only improves the spectral efficiency, but also increases the energy consumption of the system and reduces the communication energy efficiency. The aim of this paper is to explore the key theories and technologies of the green evolution of ultra-dense heterogeneous networks from two aspects: macroscopic network matching and micro resource aggregation, taking advantage of the network management capability and network diversity effect of ultra-dense heterogeneous networks. This paper first discusses the basic concept of green evolution, and then proposes three key technologies to improve network energy efficiency, which are load adaptive base station switch control, active buffer and interference sensing resource allocation. At the same time, the challenges faced by each technology in its application are also discussed.
