Small Cell标准化研究进展及长期演进策略

Small Cell Standardization Research Progress and Long-term Evolution Strategy

介绍Small Cell全球市场快速发展趋势,总结Small Cell类型及部署场景的发展趋势。介绍3GPP从R8起开始Small Cell相关标准化制定工作,特别在R12阶段,Small Cell标准课题在物理层关键技术和高层网络架构有突破性研究进展。物理层关键技术主要包括Small Cell物理层频谱效率增强、关断及发现技术、基于空口的同步方案;而高层网络架构主要研究用户面与控制面分离的候选架构。最后,展望Small Cell技术演进和网络部署前景,提出中国联通LIGHT-Net研究计划,加快宏微协同组网方案的应用部署。

Smal cel have a lot offeatures, such as huge amount, plug and play, user behavior randowm, and so on. So the traditional net-work management technology cannot meet the requirement of smal cel network optimization and maintenance. The new smal cel network management technology must have self organization and self configuration functions to meet the require-ment of smal cel network operation and maintenance. Based on the analysis of the network architecture and deployment sce-narios of smal cel , it researches on smal cel network management function and deployment strategy in many scenes, provid-ing the guidancjeo for smal cel network operation and maintenance.
