摘　　要：移动通信网的发展正面临以受限的频谱与能量大幅度提高网络容量的严峻挑战,需要从系统和网络的角度探索频谱与能量的高效利用机理与方法。提出一种全新的超蜂窝体系架构,将网络中的控制信令与业务数据传输在覆盖上进行适度分离,实现资源与业务的弹性匹配,联合优化频谱和能量效率,满足未来移动通信网大容量和低能耗的双重需求。分别介绍了超蜂窝体系架构下的网络能效理论、高能效的传输与网络协作、业务建模与高能效服务,最后给出了超蜂窝系统的演示验证平台。The development of wireless communication networks is now facing severe challenges from limited spectrum resources and stringent energy consumption constraints, which calls for system level theories and methods to efficiently utilizethe spectrum and energy. A novel hyper-cellular mobile communication architecture was proposed, which decoupled the control signaling coverage and traffic service coverage, so that network resources can be smoothly matched with traffic variations, Via the decoupled architecture, spectrum efficiency and energy efficiency can be jointly optimized, meeting the twofold requirements of high capacity and low power consumption for future mobile communications. The network energy efficiency theory, energy efficient transmission and network collaboration technologies, spatial-temporal traffic modeling and green wireless services were introduced, and the demo system of the hyper-cellular architecture was proposed.
