本文对我们过去5年来基于超蜂窝网络架构的高能效资源优化和传输机制的研究进展进行概述.针对第五代(5G)移动通信系统的关键技术,包括大规模集中/分布式天线、超密集网络、终端直传和协作多点等,总结系统能效–谱效之间的理论关系及其与时间、频率、天线和存储等物理资源的内在联系,并介绍面向信道与业务需求动态变化的高能效按需服务方法.研究结果表明,所有5G代表性技术的能效–谱效均呈现钟形曲线关系,即谱效较小时二者同时增长,否则两者存在折中关系;谱效优先的传输策略往往会较大程度地降低能效,但能效优先传输策略的谱效损失往往较小;多天线系统的能效随天线数渐近趋于零;超密集网络下全频复用在基站与用户密度之比较大时能效最高,否则部分频率重用能效更高;在基站部署缓存可以提升网络能效,当干扰小、回传容量低、内容流行时能效增益高. In this paper, we overview the research progress of the energy efficient resource optimization and transmission mechanism based on the ultra-cellular network architecture in the past five years.The key technologies for the fifth generation (5G) mobile communication system include large-scale centralized / distributed antennas, Network, terminal direct transmission and cooperation and so on, summarizes the system energy efficiency - the theoretical relationship between spectrum efficiency and its internal relations with time, frequency, antenna and storage and other physical resources, and describes the dynamic demand-oriented channel and business needs high Energy efficient on-demand service approach.The results show that all 5G representative technologies have a bell-shaped energy efficiency-spectrum effect, that is, both of them increase at the same time, otherwise, there is a compromise between the two. Otherwise, The energy efficiency is often reduced to a great extent, but the spectral efficiency loss of energy-efficient prioritized transmission strategies tends to be small; the energy efficiency of multi-antenna systems tends to zero as the number of antennas approaches zero; and the full frequency reuse of ultra- When the ratio is large, the energy efficiency is the highest, otherwise some frequency reuse is more energy-efficient. Deploying the cache at the base station can improve the network energy efficiency. When the interference is small, the return traffic is low, the content flow When high energy efficiency gains.
