第5代移动通信系统的设计与标准化进展

Overview on the Progress of Design and Standardization of the Fifth Generation of Mobile Communications System

通过对第5代移动通信系统(5G)需求指标、国际标准化组织工作计划的介绍以及基于3GPP R15的5G新空口物理层关键技术、空口协议栈过程、接入网架构与接口设计、基于服务化架构的核心网关键技术,描述了一个较为完整的5G系统设计和标准化进展情况,使读者能够对5G技术整体设计思路、方案和特点有一个清晰认识,并对5G标准化内容有较为充分地了解.

With the continuous development of information technology,the key technology and system design of the fifth generation of mobile communications system(5G)has become a hotspot in both academia and industry.A complete overview of 5G design and standardization progress,including thekey performance index(KPI)of 5G was provided,the work plan of international standardization organization on 5G,and 5G design based on 3GPP R15.Specifically,the key technology of physical layer,the protocol stack and procedure of air interface,the radio access network architecture and interface design,the key technology and architecture of core network were introduced and analyzed.We try to provide a whole picture of 5G design,from radio access network to core network.Therefore,a clear understanding of the overall design ideas,solutions and features of 5G technology,as well as the 5G standardized contents can be achieved.
