Description

一种信息传递方法、装置及系统 技术领域
本申请涉及但不限于无线通信技术，尤其涉及一种信息传递方法、装置及系统。
背景技术
分组业务的传输时延一直是无线网络运营商关注的一个重要业务指标，直接影响着终端用户的业务体验。随着移动互联网应用的迅猛发展，远程控制、车联网、虚拟现实等物联网以及相关业务对移动网络中的分组业务传输时延提出了进一步的严格要求。因此，分组业务的超低时延传输就成为了第五代移动通信技术(5G)中的一个重要研究课题。
对于5G中的超低时延业务，无线接入网需要采用超低时延的无线传输策略。其中，采用传输时间间隔(TTI，Transmission Time Interval)的时长小于1毫秒(短TTI)的无线帧进行超低时延数据传输是缩短无线传输时延的重要手段。长期演进(LTE，Long Term Evolution)协议引入短TTI功能后，网络侧无论是业务建立/重配/切换时的资源分配，还是业务保持过程中的调度，如果需要分配短TTI资源，基站(eNodeB)都需要知道用户设备(UE，User Equipment)是否支持短TTI功能。如果协议支持多种长度类型的短TTI，则eNodeB需要知道UE具体支持哪几种短TTI类型。也就是说eNodeB需要知道UE的短TTI支持能力。然而，在目前的标准状态下，eNodeB无法获取UE的短TTI支持能力。
