Description

更新系统信息的方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及更新系统信息的方法、终端设备和网络设备。
背景技术
在新无线(New Radio,NR)系统中,终端设备在进入连接态之后,可以激活一个或者多个带宽部分(Band Width Part,BWP),同时,BWP中可以包含系统信息,也可以不包含系统信息。当系统信息发生变化时,终端设备会通过当前驻留的BWP获取最新的系统信息,如果当前驻留的BWP没有系统信息,则网络设备会通过专用信令将更新后的系统信息发送给终端设备。然而,当系统信息发生变化时,终端设备需要一定时间读取通过广播发送的更新后的系统信息,在此过程中,如果网络设备指示终端设备切换BWP(例如,从BWP1切换为BWP2),终端设备无法获知如何接收更新后的系统信息。
