Abstract
本申请实施例涉及定时器运行方法、终端设备和网络设备,其中方法包括,终端设备接收第一消息,第一消息针对用于非激活态数据传输的预配置(CG)资源;终端设备根据第一消息,对第一定时器执行相应的操作,第一定时器用于维护第一定时提前量的有效性。本申请实施例可以使得终端设备明确数据传输的定时器机制以及所维护的定时提前量。
Description
本申请涉及通信领域,并且更具体地,涉及一种定时器运行方法、终端设备和网络设备。
在5G新空口(NR,New Radio)系统中,无线资源控制(RRC,Radio Resource Control)状态分为3种,分别为:RRC_IDLE(RRC空闲态)、RRC_INACTIVE(RRC非激活态)和RRC_CONNECTED(RRC连接态)。其中RRC_INACTIVE态是5G系统从节能角度考虑引入的新状态,对于RRC_INACTIVE态的用户设备(UE,User Equipment),无线承载和全部无线资源都会被释放,但UE侧和基站侧保留UE接入上下文,以便快速恢复RRC连接。网络通常将数据传输不频繁的UE保持在RRC_INACTIVE态。Rel-16标准之前,处于RRC_INACTIVE状态的UE不支持数据传输,当上行(MO,Mobile Original)或下行(MT,MobileTerminal)数据到达时,UE需要恢复连接,待数据传输完成后再释放到INACTIVE状态。对于数据量小且传输频率低的UE,这样的传输机制会导致不必要的功耗和信令开销。因此,Rel-17立项开展对RRC_INACTIVE下小数据传输(Small Data Transmission,SDT)的研究,项目目标主要有两个方向:基于随机接入过程(两步/四步)的上行小数据传输(RA-SDT)以及基于预配置资源(如CG type1)的上行小数据传输(CG-SDT)。
在RAN2#112会议上,同意通过RRC释放(RRCRelease)消息为UE配置用于非激活态数据传输的预配置资源(CG,Configured Grant Resource),并为CG-SDT引入新的时间对齐定时器(TAT,Time Alignment Timer)(本申请中简称为SDT-TAT),用于维护CG-SDT过程中定期提前量的有效性。在随后的RAN2#113e会议上,关于SDT-TAT得出进一步结论,初步定了SDT-TAT的启动/重启时机,以及SDT-TAT超时后的行为。目前,对于上行小数据传输(SDT)的定时器的运行机制以及定时器运行期间维护有效定时提前量的方法尚无明确的解决方案。
