Description

处理无线链路失败的方法、终端设备和网络设备 技术领域
本申请涉及通信领域，尤其涉及处理无线链路失败的方法、终端设备和网络设备。
背景技术
在长期演进(long term evolution，LTE)***中，在无线链路控制(radio link control，RLC)实体处于确认模式(acknowledged mode，AM)时，当存在确认模式下的协议数据单元(AMdata protocol data unit，AMD PDU)的传输次数达到最大自动重传请求(automatic repeat request，ARQ)重传次数时，触发无线链路失败(radio link failure，RLF)事件，RLC实体上报网络设备。
在LTE中，UE对主小区组(master cell group，MCG)和次小区组(secondary cell group，SCG)的RLC实体中所发生的AMD PDU达到最大重传次数都触发RLF事件。
在NR中，针对载波聚合(carrier aggregation，CA)场景下的复制数据传输，分组数据汇聚协议(packet data convergence protocol)层将生成的复制数据(即PDCP PDU和复制的PDCP PDU)分别传输到两个不同的RLC实体，两个RLC实体映射到不同的物理层载波，比如主载波(PCELL)和辅载波(SCELL)，若按照现有LTE的RLF事件，终端设备在上报网络设备时，只会上报触发RLF事件，但是对于NR中的CA这种情况下，RLC实体如果达到最大重传次数，需要重新考虑如何上报。

具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
应理解，本申请实施例的技术方案可以应用于各种通信***，例如：LTE***、LTE频分双工(frequency division duplex，FDD)***、LTE时分双工(time division duplex，TDD)、第4.5(4.5th generation，4.5G)代网络、第五代(5th generation，5G)网络、新空口(new radio，NR)等。
本申请实施例中的终端设备也可以称为终端(Terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
本申请实施例所涉及到的网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站，所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等。在采用不同的无线接入技术的***中，具有基站功能的设备的名称可能会有所不同。例如在LTE网络中，称为演进的节点B(Evolved NodeB，eNB或eNodeB)，在第三代(3rd Generation，3G)网络中，称为节点B(Node B)等等。
基站和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请的实施例对基站和终端设备的应用场景不做限定。
图1示出了根据本申请实施例的处理RLF的方法100的示意性流程图，该方法100可以由终端设备执行。
如图1所示，该方法100包括：S110，终端设备通过主载波和辅载波向网络设备发送相同的PDCP层数据。
应理解，本申请实施例可以用于CA场景下的复制传输，终端设备传输相同的PDCP层数据的主载波和辅载波可以分别指一个或多个载波，即该主载波可以为一个载波，或者包括多个载波的载波组，辅载波也可以为一个载波，或者包括多个载波的载波组。
在本申请实施例中，S110中传输的相同的PDCP层数据是指重复传输PDCP层数据包。具体地，图2示出了根据本申请实施例的复制传输PDCP层数据的示意图。如图2所示，一个PDCP实体与两个RLC实体绑定。该终端设备将待发送的第一PDCP PDU进行复制(duplication)，得到第二PDCP PDU。终端设备将该第一PDCP PDU下发到该两个RLC实体中的一个RLC实体RLC 1，将该第二PDCP PDU下发到该两个RLC实体中的另一个RLC实体RLC2。该两个RLC实体分别对收到的PDCP PDU进行处理，并通过两个不同的载波将该第一PDCP PDU和该第二PDCP PDU发送至网络设备，例如如图2所示，通过载波1和载波2分别发送，其中，该载波1可以为主载波，载波2可以为辅载波。该两个RLC实体对接收到的PDCP PDU进行处理的过程与现有技术中不进行重复传输时单个RLC实体处理PDCP PDU的方式相同，在此就不必赘述。
可选地，终端设备还可以通过多于两个载波传输该PDCP层数据，该终端设备还可以通过M个载波向该网络设备发送相同的数据包，其中M为大于或等于3的正整数。在此情况下，该终端设备可以将待发送的PDCP PDU复制，得到包括该待发送的PDCP PDU在内的M个数据包，分别通过该M个载波将该M个相同的数据包发送至网络设备，从而进一步提高数据传输的可靠性。该终端设备在通过M个载波向该网络设备发送相同的数据包的情况下处理RLF的方法与该终端设备在通过两个载波向网络设备发送相同的数据包的情况下处理RLF的方式类似。换句话说，该主载波可以该M个载波中的任意一个主载波，该辅载波可以为该M个载波中的任意一个辅载波。
应理解，终端设备用于进行重复传输功能RLC实体可以由网络设备通过RRC信令进行配置。例如，该网络设备可以配置该终端设备可以使用五个RLC实体进行重复传输，且五个RLC实体中的两个RLC实体处于激活 状态，则该终端设备可以使用该两个RLC实体进行重复传输。
在重复传输PDCP PDU层数据包的情况下，该终端设备会将待发送的第一PDCP PDU复制，得到第二PDCP PDU。终端设备将该第一PDCP PDU和该第二PDCP PDU分别发送至两个RLC实体，每个RLC实体会对接收到的PDCP PDU进行处理，并发送至MAC实体。MAC实体会分别对两个RLC层发送的数据包进行处理，再通过两个不同的载波将两个RLC层数据包发送至该网络设备。MAC层实体对RLC层数据包进行处理的过程与中不进行重复传输时MAC实体处理RLC层数据包的方式相同在此就不必赘述。
可以理解的是，本申请实施例中所称的重复传输数据包或者数据包重复传输功能中的重复传输(duplicated transmission)是指将一个数据包复制后得到两个或者两个以上的相同的数据包，分别采用不同载波传输这两个或两个以上的相同的数据包。本申请实施例中所称的重复传输并不是指自动重传请求等机制中的数据包重传(retransmission)。
可选的，在另外一些实施例中，比如双连接场景下，上述载波可以是指与不同网络设备之间的连接(link)。例如，该主载波可以为MCG中的主载波，该辅载波可以为MCG中的辅载波；或者，该主载波可以为SCG中的主载波，该辅载波可以为SCG中的辅载波，本申请实施例并不限于此。
该方法100还包括：S120，该终端设备在该辅载波对应的RLC实体中存在AMD PDU的传输次数达到最大传输次数的情况下，确定该辅载波发生RLF事件；S130，该终端设备向该网络设备发送第一RLF类型指示信息，该第一RLF类型指示信息用于指示发生该RLF事件的载波为该辅载波。
应理解，对于双连接场景，该辅载波可以为MCG中的辅载波，或者还可以为SCG中的辅载波，则终端设备确定辅载波发生RLF事件还包括具体确定该MCG中的辅载波发生RLF事件，或者为SCG中的辅载波发生RLF事件。对应的，终端设备向网络设备发送的第一RLF指示信息用于指示发生RLF事件的载波为该MCG中的辅载波或SCG中的辅载波。
类似的，该方法100还可以包括：终端设备确定主载波对应的RLC实体中存在AMD PDU的传输次数达到最大传输次数的情况下，确定该主载波发生RLF事件。
同样的，对于双连接场景，该主载波可以为MCG中的主载波，或者还可以为SCG中的主载波，则终端设备确定主载波发生RLF事件还包括具体 确定该MCG中的主载波发生RLF事件，或者为SCG中的主载波发生RLF事件。
具体地，当发生RLF事件的载波为MCG中的主载波时，可以类似现有技术中MCG的载波发生RLF事件，终端设备可以向网络设备发送RRC重建请求消息，该RRC重建请求消息用于请求与网络设备进行RRC重建。网络设备确定该发生RLF事件的载波为MCG中的主载波，根据该RRC重建请求消息，确定与终端设备进行RRC重建，则可以向该终端设备返回RRC重建信息，用于与终端设备进行RRC；或者，该网络也可以根据该RRC重建请求消息，拒绝与终端进行RRC重建。其中，该RRC重建可以为RRC connection release或RRC connetction re-establishment。
应理解，终端设备与网络设备在MCG中的主载波发生RLF事件进行RRC重建的过程可以与现有技术中MCG的载波发生RLF事件进行RRC重建的过程相同，在此不再赘述。
可选地，当发生RLF事件的载波为SCG中的主载波时，终端设备可以向网络设备发送第二RLF类型指示信息，该第二RLF类型指示信息用于指示发生RLF事件的载波为SCG中的主载波。
综上，对于双连接的场景，当发生RLF事件时，终端设备确定发生RLF事件的目标载波的类型，当该目标载波为MCG中的辅载波、SCG中的主载波或者SCG中的辅载波时，终端设备可以向网络设备发送RLF类型指示信息，通过该RLF类型指示信息指示网络设备发生RLF事件的目标载波为MCG中的辅载波、SCG中的主载波或者SCG中的辅载波。
进一步的，在目标载波发生RLF事件时，终端设备可以向网络设备发送RRC重配置信息，该RRC重配置信息用于终端设备与网络设备进行RRC重配置，其中，目标载波为MCG中的辅载波、SCG中的主载波或者SCG中的辅载波。具体地，终端设备与网络设备进行RRC重配置的过程与现有技术相同，例如与现有技术中SCG中的载波发生RLF事件需要进行RRC重配置的过程相同，在此不再赘述。
可选地，本申请实施例中的用于指示发生RLF事件的载波的类型的RLF类型指示信息可以为新增的信息，或者还可以复用现有技术的中SCG失败信息(SCG failure information)。具体地，在辅载波发生RLF事件时，或者MCG中的辅载波、SCG中的主载波或者SCG中的辅载波发生RLF事件时， 终端设备向网络设备发送的RLF类型指示信息，该RLF类型指示信息可以位于SCG failure information中，即参照现有LTE中SCG failure流程，可以在SCG failure information中添加新的字段，通过该字段携带RLF类型指示信息，该RLF类型指示信息用于指示发生RLF事件的载波的类型，但本申请实施例并不限于此。
因此，本申请实施例中的处理RLF的方法，终端设备可以通过主载波和辅载波与网络设备传输相同的数据，在辅载波对应的RLC实体发生RLF事件时，向网络设备发送RLF类型指示信息，该RLF类型指示信息可以指示发生RLF事件的载波的类型，使得网络设备可以确定发生RLF事件的载波为主载波还是辅载波，进而根据不同的载波类型，确定不同的处理方式，提高传输效率。
上文中结合图1和图2，从终端设备的角度详细描述了根据本申请实施例的处理RLF的方法，下面将结合图3，从网络设备的角度描述根据本申请实施例的处理RLF的方法。
图3示出了根据本申请实施例的处理RLF的方法200的示意性流程图，该方法200可以由网络设备执行。
如图3所示，该方法200包括：S210，网络设备通过主载波和辅载波接收终端设备发送相同的分组数据汇聚协议PDCP层数据。
该方法200还包括：S220，该网络设备接收该终端设备发送的第一RLF类型指示信息，该第一RLF类型指示信息用于指示发生RLF事件的载波为该辅载波，发生该RLF事件的该辅载波对应的RLC实体中存在AMD PDU的传输次数达到最大传输次数。
该方法200还包括：S230，该网络设备根据该第一RLF类型指示信息，确定发生该RLF事件的载波为该辅载波。
因此，本申请实施例的处理RLF的方法，终端设备与网络设备通过主载波和辅载波传输相同的数据，在辅载波对应的RLC实体发生RLF事件时，终端设备向网络设备发送RLF类型指示信息，该RLF类型指示信息可以指示发生RLF事件的载波的类型，使得网络设备可以确定发生RLF事件的载波为主载波还是辅载波，进而根据不同的载波类型，确定不同的处理方式，提高传输效率。

可选的，该方法还包括：该网络设备确定该MCG中的主载波发生该RLF事件，并向该终端设备发送RRC重建信息，该RRC重建信息用于该终端设备与该网络设备进行RRC重建。
应理解，该方法200中的网络设备可以对应方法100中网络设备，方法200中的终端设备可以对应方法100中的终端设备，在此不再赘述。
因此，本申请实施例的处理RLF的方法，终端设备可以通过主载波和辅载波与网络设备传输相同的数据，在辅载波对应的RLC实体发生RLF事件时，终端设备向网络设备发送RLF类型指示信息，该RLF类型指示信息可以指示发生RLF事件的载波的类型，使得网络设备可以确定发生RLF事件的载波为主载波还是辅载波，进而根据不同的载波类型，确定不同的处理方式，提高传输效率。
