摘　　要：2014年,IMT-2020(5G)推进组发布了第一份白皮书,第五代移动通信系统被提上日程,有望在2020年完成整个网络与系统的部署。未来的数据流量,网络连接设备总量将会发生爆炸式增长,业务需求将会发生颠覆性变化,物联网与移动互联网将会相互融合,为人们提供多元化服务,如车联网,智能家居,智慧医疗,工业监测系统,超高清3D时频等。文章介绍实现以上高速率,靠可靠性,低时延,智能化,功能多元化的5G网络实现的网络架构以及关键技术,如大规模MIMO,软件定义网,自组网技术等。2014 IMT-2020 （5G） propulsion group released the first white paper, the fifth generation mobile communication system is put on the agenda, is expected to complete the deployment of the entire network and the system in 2020. The data flow in the future, network connected devices will total explosion growth, business demand will happen to subvert the changes, networking and mobile Internet will fuse with each other, for people to provide diversified services, such as car networking, intelligent home, medical wisdom, industrial monitoring and measurement system, Ultra HD 3D frequency. The achieve the above high rate, by reliability, low latency, intelligent, diversified functions of 5g network to achieve the network architecture and key technology, such as large-scale MIMO, software defined network, ad hoe network technology.
