能效与资源优化的超蜂窝移动通信系统新架构及其技术挑战
摘要
After developing for many decades, all kinds of information technologies gradually come across the bottlenecks of capacity and energy consumption, especially in the cellular mobile communication system, where it is a great challenge to increase the network capacity under the dual constraints of limited spectrum resources and energy consumption. It is far from enough by only improving the wireless transmission technologies and hardware implementation level, and we must investigate efficient mechanisms and methods of spectrum and energy utilization from the view of the whole system. This paper is intended for the development of future mobile communication technologies and the strategic requirements of energy saving, in which a novel framework of hypercellular system is proposed and the energy efficiency of the whole cellular network is optimized. By separating the coverage of control channel and data channel, the mechanisms of soft coverage, soft resource matching, and service on-demand are introduced, the energy efficiency and network resources are jointly optimized, and the urging requirements of broadband and large capacity in the next 10–20 years will be satisfied.
