基于虚拟小区的分层异构无线组网方案

摘要

The deployment of hierarchical heterogeneous cellular network (HCN) using overlapping small cells is identified as one of the major components in solving future cellular capacity and energy efficiency problems. An enhanced networking scheme for future HCN was proposed, accomplished by adopting the phantom cell concept that splits the C-plane and U-plane. The goal is to achieve higher capacity using higher frequency bands over a range of deployment scenarios including mobility, network density, traffic handling and network complexity. The implementation related techniques and further extension of the scheme were also provided.%使用小小区和宏小区联合重叠覆盖的分层异构无线网络被认为是解决目前蜂窝网络容量和能效等问题的主要方案.本文介绍了一种基于虚拟小区(phantom cell)的分层异构无线组网方案,核心是控制平面与用户平面分离,通过令虚拟小区使用较高频段来得到高的系统容量,并且能够满足包括移动性支持、网络部署密度、业务均衡处理和网络复杂度等在内的一系列设计要求.本文还介绍了与所提方案相关的关键技术以及分层异构无线网络未来可能的发展方向.
