具体实施方式
本申请下述各实施例所提供的链路故障的处理方法、装置及终端设备适用于可实现多波束系统的移动通信系统中，在该多波束系统的移动通信系统中例如可通过载波聚合(Carrier Aggregation，简称CA)技术，集中多个小区或基站的无线资源为一个终端设备进行服务，以满足用户的容量需求和覆盖需求。该移动通信系统可以为长期演进(Long Term Evolution，简称LTE)通信系统、5G通信系统如新一代无线接入技术(new radio access technology，NR)通信系统以及后续其它可支持多波束系统的通信系统如6G通信系统。
为便于理解本申请实施例，如下以图1中示出的场景为例进行详细说明。图1为本申请实施例的终端设备的场景示意图。如图1所示，终端设备10可支持多个服务小区，即可在多个服务小区上进行信息传输。该多个服务小区中至少可包括：SpCell和SCell。即该终端设备10即可位于SpCell的范围内，还可位于SCell的范围内。
应理解，图1仅为便于理解而示例的简化示意图，该终端设备10所支持的多个服务小区，还可包括其他，而不限于图1所示的SpCell和SCell。
该多个服务小区可以为一个网络设备下的服务小区，也可为多个网络设备下的服务小区。
在一个示例中，若该终端设备10与一个网络设备(未示出)连接，该多个服务小区可以包括：该一个网络设备的小区，其中，SpCeLL为该一个网络设备的主小区(primary cell，简称PCell)，SCell为该一个网络设备下的辅小区。
在另一种示例中，若该终端设备10可与两个网络设备(未示出)即主网络设备和辅网络设备连接，则该多个服务小区可包括该主网络设备和辅网络设备下的小区。其中，主网络设备的小区可称为主小区组(Main Cell Group，简称MCG)，辅网络设备的小区可称为辅小区组(Secondary Cell Group，简称SCG)中的小区。该MCG中的主小区(primary cell，简称PCell)，以及SCG中的主服务小区(primary serving cell，简称PSCell)均可称为SpCell。MCG中的其它小区，或者，SCG中的其它小区均可称为SCell。
应理解，无论终端设备10连接一个网络设备，还是两个网络设备，终端设备10所连接的网络设备可以为接入网设备，如基本传输站(Base Transceiver Station，简称BTS)、基本站点(Node Base，简称NodeB)、演进型基站(evolutional Node B，简称eNB)，5G NR系统中的基站(如gNB)等任一接入网设备，本申请并不限定。
终端设备10还可以称为用户设备(User Equipment，简称UE)，其可以是手机(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) 中的无线终端等等。本申请的实施例对应用场景不做限定。本申请中将前述终端设备及可设置于前述终端设备的芯片统称为终端设备。
需要说明的是，在本申请实施例中，终端设备支持服务小区，可指的是，该终端设备可通过该服务小区的波束(Beam)与网络设备进行通信，下述所涉及的小区的链路可称为小区的波束对应的链路，小区的链路故障还可称为波束故障(beam failure)。
如下结合多个示例对本申请实施例提供的各方案进行说明。图2为本申请实施例提供的一种链路故障的处理方法的流程图。该图2所示的链路故障的处理方法可终端设备通过软件和/或硬件的方式实现。如图2所示，该链路故障的处理方法可包括如下：
S201、检测SCell的链路是否发生故障。
该SCell的链路还可称为SCell的波束对应的链路。
具体实现中，终端设备可测量该SCell上的下行控制信道所对应的参考信号(例如CSI-RS信号，同步信号块SS/PBCH block)的信号质量，并确定测量得到的该信号质量，是否满足预设条件如块误码率(block error rate，简称BLER)对应的预设条件等。若该信号质量好于预设条件，则可确定该SCell的链路未发生故障。反之，若该信号质量差于预设条件(根据系统配置，可能需要连续多次都差于预设条件)，则可确定SCell的链路发生故障。
其中，该下行信道可以为物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)。参考信号例如可以包括：(Channel State Information-Reference Signals，简称CSI-RS)和/或同步信号块(SS/PBCH block，简称SSB)。
其中，SS为同步信号(synchronization signals)，PBCH为物理广播信道块(physical broadcast channel，简称PBCH)。
若通过执行S201确定SCell的链路发生故障，则继续执行下述S202。
若通过执行S201确定SCell的链路未发生故障，便无需执行下述各步骤。
S202、若该SCell的链路发生故障，则根据该SCell对应的SpCell的链路的状态，确定该SCell的链路故障恢复是否失败，和/或，是否停止进行该SCell的链路故障恢复。
由于SCell通常是与SpCell配合使用的，该SCell对应的SpCell可以为与该SCell相配合的SpCell。
该SpCell的链路的状态可包括如下中的至少一种状态：该SpCell的链路是否发生故障、SpCell的链路故障恢复是否失败、该SpCell是否出现无线链路故障(Radio Link Failure，简称RLF)等。
由于SCell所需的一些参数需通过SpCell进行传输，因而可在SCell的链路发生故障的情况下，根据该SpCell的链路的状态，确定该SCell的链路故障恢复是否失败，和/或，是否停止进行该SCell的链路故障恢复。
其中，是否停止进行该SCell的链路故障恢复指的是，是否停止进行该SCell的链路故障恢复的未执行操作。
在该方法中，可根据该SpCell的链路的状态，确定该SCell的链路故障恢复是否失败；或者，根据该SpCell的链路的状态，确定是否停止进行该SCell的链路故障恢复；或者，还可根据该SpCell的链路的状态，确定该SCell的链路故障恢复是否失败，以及是否停止进行该SCell的链路故障恢复。
本申请实施例提供的链路故障的处理方法，可通过检测SCell的链路是否发生故障，若该SCell的链路发生故障，则根据该SCell对应的SpCell的状态，确定该SCell的链路故障恢复是否失败，和/或，是否停止进行该SCell的链路故障恢复。该链路故障的处理方法可在SCell的链路发生故障的情况下，根据该SpCell的状态，预先确定了SCell的链路故障恢复结果，和/或，SCell的链路故障恢复流程中的操作执行情况，明确了终端设备的操作，避免一些非避免操作，减少设备功耗。
在一种可能的实现方式中，在上述方法的基础上，上述S202中若该SCell的链路发生故障，则根据该SCell对应的SpCell的链路的状态，确定该SCell的链路故障恢复是否失败，和/或，是否停止进行该SCell的链路故障恢复可包括：
若该SpCell的链路发生故障，则确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。
在该实现方式中，若SCell的链路发生故障，可检测该SCell对应的SpCell的链路是否发生故障，若该SpCell的链路发生故障，则确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。即，在SCell的链路和SpCell的链路均发生故障的情况下，便可确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。
检测该SpCell的链路是否发生故障的具体实现可以与上述S201中检测SCell的链路是否发生故障的实现类似，具体参照上述，在此不再赘述。
在若SCell的链路发生故障的情况下，若该SpCell的链路也发生故障，由于SCell所需的一些参数需通过SpCell进行传输，则可确定该SCell的链路故障恢复会失败，无需继续进行SCell的链路故障恢复，因而，可停止进行SCell的链路故障恢复。
若该SCell的链路发生故障的情况下，而该SpCell的链路未发生故障，则可确定该SCell的链路故障恢复可能会成功，因此可确定不停止进行SCell的链路故障恢复，即可尝试进行SCell的链路故障恢复。
示例地，该终端设备可通过测量接收到参考信号，确定满足预设条件的参考率信号。该预设条件例如可以为层1的参考信号接收功率(Reference Signal Receiving Power，简称RSRP)、层1的参考信号接收质量(Referense Signal Received Quality，简称RSRQ)或者层1的信号与干扰加噪声比(Layer1-Signal to Interference plus Noise Ratio，简称L1-SINR)等至少一个参数的预设条件。
若该终端设备未选择到满足该预设条件的参考信号，则可通过基于竞争的随机接入(contention-based random access)方式接入网络设备的SCell。
在一种方式中，若该终端设备选择到满足该预设条件的参考信号，则可通过该参考信号对应的物理随机接入信道物理随机接入信道(Physical Random Access Channel，简称PRACH)向网络设备发送链路故障恢复请求，又称波束故障恢复请求(beam failure recovery request)或者随机接入信息等。
在另一种方式中，该终端设备可向网络设备发送物理上行控制信道(Physical Uplink Control CHannel，简称PUCCH)，该PUCCH可包括：该参考信号对应的链路的标识等信息。该参考信号对应的链路可以为一个或多个，该参考信号对应的链路还可称为候选链路，如候选波束(candidate beam)对应的链路。
在又一种方式中，该终端设备可向网络设备发送介质访问控制的控制单元(Media Access Control-Control Element，简称MAC CE)信令，该MAC CE指令可包括：该参考信号对应的链路的标识等信息。该参考信号对应的链路可以为一个或多个，该参考信号对应的链路还可称为候选链路，如候选波束(candidate beam)对应的链路。
终端设备在向网络设备发送链路故障恢复请求、或者通过PUCCH或者MAC CE指令向网络设备上报目标链路等任一的情况下，还可监听网络设备返回的响应。当接收到网络设备返回的响应，便可确定该SCell的链路故障恢复成功。
本申请实施例提供的链路故障的处理方法，可在SCell和该SCell对应的SpCell的链路均发生故障的情况下，预先确定该SCell的链路故障恢复会失败和/或停止进行该SCell的链路故障恢复，可避免终端设备进行SCell的非必要操作，减少了终端设备的功耗。
在另一种可能的实现方式中，在上述方法的基础上，上述S202中若该SCell的链路发生故障，则根据该SCell对应的SpCell的链路的状态，确定该SCell的链路故障恢复是否失败，和/或，是否停止进行该SCell的链路故障恢复可包括：
若该SpCell的链路发生故障，且，该SpCell的链路故障恢复流程失败，则确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。
在该另一种可能的实现方式中，若该SCell的链路发生故障，可检测该SCell对应的SpCell的链路是否发生故障，若该SpCell的链路发生故障，可进行该SpCell的链路故障恢复，若该SpCell的链路故障恢复失败，则确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。
该SpCell的链路故障恢复流程可与上述SCell的链路故障恢复流程类似，具体参照上述，在此不再赘述。
若该SpCell的链路故障恢复流程中，若该终端设备未接收到网络设备返回的响应，则可确定该SpCell的链路故障恢复失败。
具体地，若该终端设备未接收到网络设备返回的响应，该终端设备再次向网络设备发送PRACH或者，通过PUCCH或者MAC CE指令，以指示该 目标链路。
当该终端设备满足下述任一条件，便可确定该SpCell的链路故障恢复失败：
上报该目标链路的次数大于或等于预设数值，而一直未接收到该网络设备返回的响应；
在第一预设时间段内该SpCell的链路故障恢复未成功；
在第二预设时间段内未选择到满足预设条件的参考信号。
无论该SpCell的链路故障恢复是否恢复成功，该SCell的链路故障恢复都有可能失败。
若该SpCell的链路故障恢复失败，SCell的链路故障恢复失败的几率较大，因而在此情况下，确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，其准确度较高。
本申请实施例的方法，可在SCell和该SCell对应的SpCell的链路均发生故障的情况下，而该SpCell的链路故障恢复失败的情况下，确定SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，有效提高了判断准确度。
在又一种可实现方式中，上述S202中若该SCell的链路发生故障，则根据该SCell对应的SpCell的链路的状态，确定该SCell的链路故障恢复是否失败，和/或，是否停止进行该SCell的链路故障恢复可包括：
若该SpCell出现RLF，则确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。
在该另一种实现方式中，若该SCell的链路发生故障，可检测该SCell对应的SpCell的链路是否发生故障，若该SpCell的链路发生故障，还确定该SpCell是否出现RLF；若该SpCell出现RLF，则确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。
当该SpCell的链路即该SpCell的波束对应的链路发生故障，该SpCell的无线链路(radio link)可能发生故障，也可能不发生故障。
无论该SpCell是否出现无线链路故障，该SCell的链路故障恢复均可能失败。而在该SpCell出现无线链路故障的情况下，该SCell的链路故障恢复失败的几率较大，因而在此情况下，确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，其确定准确度较高。
该方法中，若该SpCell出现无线链路失败，可无需进行SpCell的链路故障恢复，避免一些非避免操作，减少了终端设备的功耗。
本申请实施例的方法，可在SCell和该SCell对应的SpCell的链路均发生故障的情况下，而该SpCell出现RLF的情况下，确定SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，有效提高了判断准确度。
可选的，在上述方法的基础上，若通过执行上S201确定SCell的链路发生故障，则该方法还可包括：
若该SCell的第一定时器到期，则确定该SCell的链路故障恢复失败，和 /或，停止进行该SCell的链路故障恢复；该第一定时器为去激活定时器。
该SCell的第一定时器可为辅小区去激活定时器(sCellDeactivationTimer)，其也可称为失效定时器。
对应每个服务小区，可具有一个定时器，以记录该服务小区的链路的故障时长。
需要说明的是，该第一定时器到期的情况下，可直接确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复；还可结合其他的一些判定条件，在其它判定条件也达到的情况下，便可确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。
该其它的判定条件可包括下述至少一个：
如上所示的SpCell的链路发生故障、如上所示的SpCell的链路故障恢复失败、如上所示的SpCell出现RLF。
针对该其它的判定条件，其具体的实现过程参照上述，在此不再赘述。
本申请实施例的方法，可在SCell的链路发生故障的情况下，并且该SCell的失效定时器到期的情况下，确定SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，有效提高了判断准确度。
在本申请实施例中，可根据该SCell的状态，启动或重启该第一定时器。该SCell的状态可包括如任一状态：
该SCell的链路发生故障；
该SCell的链路发生故障，且，存在满足预设条件的参考信号；
在该SCell的故障恢复流程中，向网络设备发送链路故障恢复请求时或之后。
也就是说，本申请实施例的方法中，可在该SCell的链路发生故障时，便启动或重启该第一定时器；也可在该SCell的链路发生故障，且，存在满足预设条件的参考信号时，则启动或重启该第一定时器；还可在该SCell的故障恢复流程中，向网络设备发送链路故障恢复请求时或之后，启动或重启该第一定时器。
在本申请的方法中，可基于该SCell的状态，启动或重启动该第一定时器，而无需在收发数据的情况下，启动或重启动第一定时器，实现了第一定时器的提前启动或重启动，以争取更多的时间进行操作，避免了过早地进行SCell的去激活。
需指出的是，该方法中，可根据该目标链路通过PRACH向网络设备发送链路故障恢复请求，也可通过PUCCH或者MAC CE信令等向网络设备发送链路故障恢复请求。
可选的，该方法还可包括：
若接收到该网络设备返回的响应，则确定不启动或不重启该第一定时器
针对如上所示的SCell的第一定时器，也就是SCell的去激活定时器，当终端设备接收到该网络设备返回的响应，则可确定SCell的链路故障恢复成功，则便无需启动该第一定时器，因而确定不启动或不重启该第一定时器。
该方案，在接收到该网络设备返回的响应的情况下，确定不启动或不重启该第一定时器，可避免非必要的操作，节省功耗。
在SCell的链路故障恢复失败的情况下，本申请实施例还可提供一种链路故障的处理方法。在本申请实施例中，终端设备可采用上述图2-图5中任一所示的方法确定SCell的链路故障恢复是否失败，和/或，是否停止进行该SCell的链路故障恢复，在此不再赘述。
该终端设备还可采用其它的方式确定该SCell的链路故障恢复失败，和/或，是否停止进行该SCell的链路故障恢复。
对于该其它的方式，该终端设备可确定该SCell的链路发生故障的情况下，便进行SCell的链路故障恢复。具体的SCell的链路故障恢复流程可参见上述，在此不再赘述。在进行SCell的链路故障恢复的过程中，上报该目标链路的次数大于或等于预设数值，而一直未接收到该网络设备返回的响应，便可确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。或者，在第三预设时间段内该SCell的链路故障恢复未成功，则确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。或者，在第四预设时间段内未选择到满足预设条件的参考信号，则确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复。
若终端设备确定该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，则终端设备还可执行下述至少一个操作：
向该SpCell发送第一通知，该第一通知可用以指示该SCell的链路故障恢复失败；
在SpCell上传输PUCCH；
停止在该SCell上接收PDCCH；
启动该SCell的第二定时器，并在该第二定时器到期之前，未接收到该SCell的重新配置或激活信令，则去激活该SCell；
去激活该SCell；
向网络设备发送第二通知，该第二通知用以指示该SCell上的链路故障恢复失败。
具体地，终端设备可通过主处理器或者SCell的逻辑处理单元发送该第一通知
当终端设备确定SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，而该SpCell上的链路未故障或者SpCell的链路故障恢复成功，则终端设备可将配置在SCell的PUCCH，回落至该SpCell，用以在该SpCell上传输PUCCH，保证了PUCCH的正常传输。其中，该PUCCH可以为CA对应的PUCCH。可选的，在终端设备通过该SpCell上传输PUCCH之前，可接收网络设备发送的资源配置信息，该资源配置信息可以为该PUCCH在SpCell上的资源对应的资源配置信息。
当终端设备确定SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，可通过停止在该SCell上的PDCCH监听操作，以停止在该 SCell上接收PDCCH，从而减少不避免的功耗。
该SCell的第二定时器可以为上述去激活定时器，也可以复用该SCell的其它任一定时器，还可以预设的用于在SCell的链路故障恢复失败的情况下使用的定时器。该SCell的重新配置信令可以为该SCell的无线资源控制(Radio Resource Control，简称RRC)信令，该SCell的激活信令可以为该SCell的MAC CE信令。
在本申请实施例的方案中，终端设备可在该SCell的链路故障恢复失败，和/或，停止进行该SCell的链路故障恢复，并且在第二定时器的时间到期之前，而未接收到该SCell的重新配置或激活信令，则去激活该SCell。也可在该SCell的链路故障恢复失败和/或，停止进行该SCell的链路故障恢复的情况下，便直接去激活该SCell。通过去激活该SCell，可使得SCell失效，用以释放SCell的资源，提高了资源的利用率。
该终端设备在该SCell的链路故障恢复失败和/或，停止进行该SCell的链路故障恢复的情况下，直接向网络设备发送第二通知以指示该SCell上的链路故障恢复失败；也可在该SCell的链路故障恢复失败和/或，停止进行该SCell的链路故障恢复，并执行上述各操作的情况下，向网络设备发送该第二通知以指示该SCell上的链路故障恢复失败，例如可在去激活SCell的情况下，向网络设备发送该第二通知以指示该SCell上的链路故障恢复失败。终端设备向网络设备发送该第二通知以指示该SCell上的链路故障恢复失败，可使得终端设备释放该SCell的资源，提高了资源的利用率。
