本申请主张在2020年3月24日在中国提交的中国专利申请号No.202010215187.2的优先权,其全部内容通过引用包含于此。
本发明实施例涉及无线通信技术领域,尤其涉及一种无线链路监测方法、终端及网络侧设备。
用户设备(User Equipment,UE,也称为终端)的连接失败包括以下几种:
1)切换失败(如,在规定时间内切换没有完成(如,定时器t304超时))。
2)辅小区组(Secondary Cell Group,SCG)切换(change)失败(如,在规定时间内接入新的SCG没有完成(如,定时器t307超时))。
3)无线链路失败(Radio Link Failure,RLF)。
其中,该“无线链路失败”包括:
1)物理层失步(如,定时器t310超时)。
2)媒体接入控制(Medium Access Control,MAC)层的随机接入失败(如,达到最大随机接入尝试次数)。
3)无线链路控制(Radio Link Control,RLC)层达到最大重传次数指示(如,达到最大RLC层最大重传次数)。
4)波束失败(如,波束恢复过程失败)。
物理层失步的检测又被称为无线链路监测(Radio Link Monitoring,RLM)是在主小区(PCell)和主辅小区(PSCell)分别进行。
UE的物理层会向无线链路控制(Radio Resource Control,RRC)层提供物理层链路状态(如PCell或PSCell)的指示信息:
1)在信道质量好的时候指示"同步(in-sync)"。
2)在信道质量差的时候指示"失步(out-of-sync)"。
当UE接收到N310个连续的"out-of-sync"指示后,UE启动T310定时器。
当UE接收到N311个连续的"in-sync"指示后,如果T310定时器正在运行,则UE停止该T310定时器。
如果T310定时器超时,则UE认为该监测的无线链路出现问题。
现有技术中,1个服务小区(或带宽部分(Bandwidth Part,BWP))的传输信号质量只来源于1个传输节点(Transmission Point,TPR),因此只需要对该服务小区(或BWP)进行RLM即可。但是,当1个服务小区(或BWP)的传输信号质量来源于多个传输节点时,如何进行该服务小区(或BWP)的多个传输节点的信号质量检测是需要解决的问题。
