本申请基于申请号为202110357630.4、申请日为2021年4月1日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
本公开涉及通信技术领域,尤其涉及一种终端设备的控制方法、装置及存储介质。
在多连接场景下,分为一个主小区组(Master Cell Group,MCG)和一至多个辅小区组(Secondary Cell Group,SCG),其中,主节点(Master Node,MN)侧的小区组被称为主小区组,通常由一个主小区(Primary Cell,PCell)和辅小区(Secondary Cell,SCell)(辅小区不是必须项)组成。辅节点(Secondary Node,SN)侧的小区组可以被称为辅小区组,同样由一个主小区(Primary SCG Cell,PSCell)和辅小区SCell组成。
在一些应用场景中,考虑到节能,终端设备(例如,用户设备User Equipment,UE)可以在数据传输量较小的情况下,将SCG侧设置为去激活态(deactivated),在去激活态下,UE不进行SCG侧物理下行控制信道(Physical Downlink Control Channel,PDCCH)的监控,不进行上行物理共享信道(Physical Uplink Shared Channel,PUSCH)传输,不进行辅小区组SCG侧数据的传输,但仍然可以进行无线资源管理(Radio Resource Management,RRM)的测量和上报。
而定时提前(Time Advance,TA)用于UE上行传输数据的控制,该定时提前TA是指UE传输上行数据的***帧,相比对应的下行帧提前一定的时间。而定时提前时间(Time Advance Timer,TAT)是控制TA的一个定时器,如果TAT超时,UE可以进行随机接入(Random Access Channel,RACH)过程获得TA。
相关技术中,在激活辅小区组SCG时,在该SCG侧PSCell的TAT未超时的情况下,终端设备可能与网络维持同步;也可能由于终端设备的移动速度快等原因而导致与网络失步。那么如何保障终端设备和网络设备之间的通信稳定亟需解决。

上述确定目标SCG的定时提前时间TAT是否超时,可以具体是在根据激活指令设置目标SCG的状态的过程中,确定目标SCG的定时提前时间TAT是否超时,从而能够有效提升终端设备控制的时效性。
例如,在根据激活指令将目标SCG的状态由去激活态设置为激活态时,可以实时地确定目标SCG的定时提前时间TAT是否超时。

从而本公开的实施例中,支持在TAT未超时时,直接启动指定定时器;或者,在TAT未超时时,且确定开始监听物理下行控制信道PDCCH时,启动指定定时器;或者,在TAT未超时时,且在终端设备发送上行UL信号/信令/数据之后,启动指定定时器,从而提供了灵活的启动指定定时器的方式,使得本公开提供的终端设备的控制方法能够具有更好的适用性,辅助准确地、适时地启动指定定时器。
在启动指定定时器之后,确定指定定时器是否超时,在超时的情况下,终端设备可以执行以下S204、S205、S206和S207中的任意一项或者多项操作。
S204:若指定定时器超时,则发起随机接入,以接入目标SCG的主小区。

举例而言,若指定定时器超时,则控制终端设备向网络设备发送第一消息,第一消息用于指示目标SCG发生无线链路失败事件,而后,可以等待网络设备决策。
又例如,还可以在指定定时器超时,且终端设备未接收到PDCCH,和/或终端设备未接收到网络设备反馈的下行消息时,则控制终端设备向网络设备发送第一消息。
S206:若指定定时器超时,则根据激活指令,维持目标SCG处于激活态。
