摘要
5G网络之所以能连接新的行业,催生新的服务,带来新的用户体验,其中一个重要原因就是5G的帧结构发生了较大变化。5G的应用场景是万物互联,帧结构必须灵活多变,才能适应不同应用场景的大量业务需要。首先简介了TDLTE的帧结构,其次总结了面向5G的三大应用场景,引申出市场对5G系统的特殊需求,最后分析了5G的帧结构,并讨论了5G帧结构定义的作用和意义。
One of the important reasons why 5G network can connect new industries,generate new services and bring new user experience is that the frame structure of 5G has changed greatly. The application scenario of 5G is interconnection of all things,the frame structure must be flexible to adapt to different business needs of application scenarios. Firstly,the frame structure of TD-LTE is introduced. Secondly,the three application scenarios for 5G are summarized. The special needs of the market to 5G system are drawn out. Finally,the frame structure of 5G is analyzed. The role and significance of the definition of 5G frame structure are discussed.
