在本发明实施例中，术语“通信网络”或“无线通信网络”可以指符合如下任意通信标准的网络，例如长期演进(LTE，Long Term Evolution)、增强的长期演进(LTE-A， LTE-Advanced)、宽带码分多址接入(WCDMA，Wideband Code Division Multiple Access)、高速报文接入(HSPA，High-Speed Packet Access)等等。
并且，通信系统中设备之间的通信可以根据任意阶段的通信协议进行，例如可以包括但不限于如下通信协议：1G(generation)、2G、2.5G、2.75G、3G、4G、4.5G以及未来的5G、新无线(NR，New Radio)等等，和/或其他目前已知或未来将被开发的通信协议。
在本发明实施例中，术语“网络设备”例如是指通信系统中将终端设备接入通信网络并为该终端设备提供服务的设备。网络设备可以包括但不限于如下设备：基站(BS，Base Station)、接入点(AP、Access Point)、发送接收点(TRP，Transmission Reception Point)、广播发射机、移动管理实体(MME、Mobile Management Entity)、网关、服务器、无线网络控制器(RNC，Radio Network Controller)、基站控制器(BSC，Base Station Controller)等等。
其中，基站可以包括但不限于：节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB)，等等，此外还可包括远端无线头(RRH，Remote Radio Head)、远端无线单元(RRU，Remote Radio Unit)、中继(relay)或者低功率节点(例如femto、pico等等)。并且术语“基站”可以包括它们的一些或所有功能，每个基站可以对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。
在本发明实施例中，术语“用户设备”(UE，User Equipment)或者“终端设备”(TE，Terminal Equipment)例如是指通过网络设备接入通信网络并接收网络服务的设备。终端设备可以是固定的或移动的，并且也可以称为移动台(MS，Mobile Station)、终端、用户台(SS，Subscriber Station)、接入终端(AT，Access Terminal)、站，等等。
其中，终端设备可以包括但不限于如下设备：蜂窝电话(Cellular Phone)、个人数字助理(PDA，Personal Digital Assistant)、无线调制解调器、无线通信设备、手持设备、机器型通信设备、膝上型计算机、无绳电话、智能手机、智能手表、数字相机，等等。
再例如，在物联网(IoT，Internet of Things)等场景下，终端设备还可以是进行监控或测量的机器或装置，例如可以包括但不限于：机器类通信(MTC，Machine Type  Communication)终端、车载通信终端、设备到设备(D2D，Device to Device)终端、机器到机器(M2M，Machine to Machine)终端，等等。

以下通过示例对本发明实施例的场景进行说明，但本发明不限于此。
图1是本发明实施例的通信系统的一个示意图，示意性说明了以终端设备和网络设备为例的情况，如图1所示，通信系统100可以包括网络设备101和终端设备102。为简单起见，图1仅以一个终端设备和一个网络设备为例进行说明，但本发明实施例不限于此。
在本发明实施例中，网络设备101和终端设备102之间可以进行现有的业务或者未来可实施的业务。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
NR系统中引入了一种终端设备(也可称为用户设备)自主恢复的机制，即波束失败恢复机制。例如，终端设备进入连接态之后，网络设备会为终端设备提供专用配置。根据网络设备发送的专用配置，终端设备在发生波束失败并且存在候选波束时，可以使用该专用配置规定的资源或者基于竞争的资源，发送波束失败恢复请求；并且在该专用配置规定的接收时间窗口内、在指定的资源位置上等待网络设备的反馈。如果在该接收时间窗口内接收到网络设备的反馈，则可以认为波束失败恢复过程成功，否则认为该波束失败恢复过程失败。
图2是本发明实施例的波束失败恢复过程的示意图，如图2所示，网络设备(例如gNB)可以预先给终端设备发送用于波束失败恢复的专用配置。在终端设备确定进行波束失败恢复时，向网络设备发送波束失败恢复请求，并接收网络设备对于该请求的响应。
网络设备为终端设备提供的专用配置，例如可以包括至少如下之一：
用于确定波束失败的参数，例如NrOfBeamFailureInstance；
用于确认某个波束是不是候选波束的阈值，例如CandidateBeamThreshold；
用于发送波束失败恢复请求的随机接入资源，例如PRACH-resource-dedicated-BFR；
用于发送波束失败恢复请求的前导码索引，例如ra-PreambleIndexConfig-BFR；
用于发送波束失败恢复请求的限制，例如PreambleTransMax-BFR；
用于对网络设备的响应进行接收的配置信息，例如ResponseWindowSize-BFR以及Beam-Failure-Recovery-Response-CORESET。
值得注意的是，以上仅对用于波束失败恢复的专用配置进行了示例性说明，但本发明不限于此，例如还可以包括其他的参数；关于用于波束失败恢复的专用配置的其他内容，还可以参考相关技术而不再赘述。
另一方面，在NR中，5G系统支持无线链路失败以及重建过程。例如，物理层问题、随机接入问题、无线链路控制(RLC，Radio Link Control)问题都使得终端设备的无线资源控制(RRC，Radio Resource Control)层确定无线链路失败。
再例如，在无线链路失败发生在主基站且安全已经激活的情况下，终端设备将发起连接重建过程以恢复连接。在连接重建后，终端设备可以向网络设备发送无线链路失败报告。在无线链路失败发生在辅基站的情况下，终端设备将会向主基站发送辅小区组(SCG，Secondary Cell Group)失败信息消息(SCGFailureInformation message)，由网络设备来决定释放或更换辅基站。
再例如，无线链路失败报告和SCG失败信息消息均包括失败类型，均可以向网络设备提供失败发生的原因，例如物理层问题或随机接入问题等。
以下将以NR系统为例，对本发明实施例进行说明；但本发明不限于此，还可以适用于任何存在类似问题的系统中。
实施例1
本发明实施例提供一种波束失败恢复的配置方法。
图3是本发明实施例的波束失败恢复的配置方法的示意图，示出了终端设备侧的情况。如图3所示，波束失败恢复的配置方法300包括：
步骤301，终端设备接收网络设备发送的用于波束失败恢复的测量阈值和测量参数；以及
步骤302，终端设备基于所述测量阈值和测量参数，对待评估波束进行测量和/或评估。
在本实施例中，网络设备可以在用于波束失败恢复的专用配置中包括测量阈值和测量参数。所述测量参数包括至少如下之一：波束测量结果大于所述测量阈值的持续时间、波束测量结果大于所述测量阈值的实例数目、对波束进行测量的测量模式、对测量结果进行过滤的过滤因子。但本发明不限于此，还可以包括其他的参数。
由此，通过引入一个或多个测量参数，网络设备能够更好地控制终端设备进行物理层测量，或者，能够更好地控制终端设备对物理层测量结果进行处理；这样，终端设备在确定某一个波束是否为候选波束时，能够使用统一标准的测量结果，能够提升候选波束的准确性。
在一个实施方式中，终端设备可以基于所述测量阈值以及所述待评估波束的测量结果，确定所述待评估波束为用于波束失败恢复的候选波束。
在一个实施方式中，所述待评估波束可以包括至少如下之一：具有可用测量结果的波束、服务波束外具有可用测量结果的波束、配置了用于波束失败恢复的资源且具有可用测量结果的波束、服务波束外配置了用于波束失败恢复的资源且具有可用测量结果的波束。
在一个实施方式中，所述测量模式可以由如下信息确定：一次测量中测量实例的数目和连续两个测量实例之间的间隔，或者，一次测量的持续时间和连续两个测量实例之间的间隔。
在一个实施方式中，终端设备可以基于测量模式对波束进行一次或多次测量。
图4是本发明实施例的波束失败恢复的配置方法的另一示意图，示出了终端设备侧和网络设备侧的情况。如图4所示，波束失败恢复的配置方法400包括：
步骤401，网络设备向终端设备发送用于波束失败恢复的测量阈值和测量参数；
步骤402，终端设备基于所述测量参数对波束进行多次测量。
如图4所示，波束失败恢复的配置方法400还可以包括：
步骤403，终端设备对所述多次测量的测量结果进行统计；
例如，终端设备可以对该波束的所有测量结果进行平均；但本发明不限于此，还可以使用其他的统计方式，例如求和、求方差，等等。
步骤404，终端设备基于统计结果确定所述波束为波束失败恢复的候选波束。
例如，在所述统计的结果大于所述测量阈值的情况下，终端设备确定所述波束为波束失败恢复的候选波束。
再例如，在一段持续时间内，在所述待评估波束的多个测量值均大于所述测量阈值的情况下，或者多个测量值的平均值大于所述测量阈值的情况下，确定所述待评估波束为波束失败恢复的候选波束。其中，该持续时间例如可以是测量参数中的“波束测量结果大于所述测量阈值的持续时间”，或者也可以是终端设备自己确定的时间，本发明不限于此。
再例如，在所述待评估波束的连续多个测量值均大于所述测量阈值的情况下，或者连续多个测量值的平均值大于所述测量阈值的情况下，确定所述待评估波束为波束失败恢复的候选波束。其中，该连续多个测量值的个数例如可以是测量参数中的“波束测量结果大于所述测量阈值的实例数目”，或者也可以是终端设备自己确定的个数，本发明不限于此。
值得注意的是，以上附图4仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图4的记载。
在另一个实施方式中，终端设备还可以基于过滤因子对多次测量的测量结果进行过滤计算；以及基于所述过滤计算后的结果确定所述待评估波束为波束失败恢复的候选波束。
值得注意的是，以上各种实施方式可以单独执行，也可以将任意两个或以上的方式结合起来执行；以下通过多个例子进行示例性说明。
例如，当网络设备为终端设备配置用于评估一个波束是不是候选波束的测量阈值CandidateBeamThreshold时，还可以配置“波束测量结果大于所述测量阈值的持续时间”参数，例如表示为Time-To-Transmit。在波束失败发生的情况下，终端设备对所有待评估的波束进行评估。如果某个波束在时间Time-To-Transmit内的平均测量值或所有测量值大于测量阈值CandidateBeamThreshold，则终端设备认为该波束是用于波束失败恢复的候选波束；否则，认为该波束不是候选波束。
再例如，当网络设备为终端设备配置用于评估一个波束是不是候选波束的测量阈值CandidateBeamThreshold时，还配置了“波束的测量结果大于所述测量阈值的实例数目”参数，例如表示为NrOfBeamAvailiabilityInstance。在波束失败发生的情况下，终端设备对所有待评估的波束进行评估。如果某个波束的连续NrOfBeamAvailiability  Instance个测量值均大于阈值CandidateBeamThreshold，或者，连续NrOfBeam AvailiabilityInstance个测量值的平均值大于阈值CandidateBeamThreshold，则终端设备认为该波束是用于波束失败恢复的候选波束；否则，认为该波束不是候选波束。
值得注意的是，这里的待评估波束可以是如下的至少之一：任何有可用测量结果的波束；服务波束外任何有可用测量结果的波束；配置了用于波束失败恢复专用资源且有可用测量结果的波束；服务波束外配置了用于波束失败恢复专用资源、且有可用测量结果的波束；但本发明不限于此。
再例如，网络设备为终端设备配置了测量模式PatternOfMeasInstance、波束测量结果大于阈值的持续时间Time-To-Transmit以及过滤因子k。其中测量模式PatternOf MeasInstance又包括一次测量评估中测量实例的总数NrOfMeasInstance和连续两个测量实例之间的间隔GapOfMeasInstance。终端设备可以根据该测量模式得到某个待评估波束的一系列测量结果，并经过过滤因子k进行过滤计算，得到的计算结果用于评估波束。如果该时间Time-To-Transmit内该计算结果都比预设阈值高，则终端设备认为该波束是候选波束，可以用于波束失败恢复；否则认为该波束不是候选波束。
由上述实施例可知，终端设备接收网络设备发送的用于波束失败恢复的测量阈值和测量参数；由此，终端设备能够根据网络设备的配置获得准确的波束测量结果，进而能够准确地确定候选波束，减少不成功的波束失败恢复。
实施例2
本发明实施例提供一种波束失败恢复的指示方法。
图5是本发明实施例的波束失败恢复的指示方法的示意图，示出了终端设备侧的情况。如图5所示，波束失败恢复的指示方法500包括：
步骤501，终端设备确定其发生波束失败；以及
步骤502，终端设备向网络设备发送用于移动鲁棒性优化的指示信息。
在本实施例中，所述移动鲁棒性优化(MRO，Mobility Robustness Optimization)可以包括：保持或调整波束失败恢复的参数。例如，网络设备根据该指示信息对用于确定候选波束的阈值CandidateBeamThreshold进行调节。
在本实施例中，所述指示信息包括至少如下之一：波束标识信息、波束失败指示、波束失败恢复成功指示、波束失败恢复失败指示、可用测量信息。但本发明不限于此， 还可以包括其他的信息。
由此，网络能够收集一个或多个终端设备上报的信息，可以判断服务范围内的连接用户配置的参数(例如CandidateBeamThreshold)是否合适。如果配置的参数不合适，会导致大量终端设备发生不成功的波束失败恢复的话，网络设备可以对所述参数进行调节，从而能够控制终端设备获得更加准确的测量结果。
在一个实施方式中，所述波束标识信息可以包括：波束对应的同步信号块(SSB，Synchronization Signal Block)的索引，和/或，波束对应的信道状态信息参考信号(CSI-RS，Channel State Information Reference Signal)的标识。其中，所述波束标识信息所对应的波束包括至少如下之一：波束失败恢复发生前的服务波束、终端设备确定能够用于波束失败恢复的候选波束、在终端设备使用多个候选波束发送波束失败恢复请求的情况下非最后使用的候选波束。
例如，波束标识信息可以表示为：
Figure PCTCN2018071358-appb-000001
或者，波束标识信息也可以表示为：
Figure PCTCN2018071358-appb-000002
在一个实施方式中，所述指示信息可以被承载于如下报告或消息中的至少之一：无线链路失败报告、辅小区组失败信息消息、主小区组上报消息、辅小区组上报消息。但本发明不限于此。
其中，所述波束失败指示、所述波束失败恢复成功指示和所述波束失败恢复失败指示中的至少之一，可以被承载于无线链路失败报告和/或辅小区组失败信息中的信息元素(IE，Information Element)中，例如rlf-Cause或failureType IE中；但本发明 不限于此。
例如，在该指示信息包括在无线链路失败报告(RLF-Report)里的情况下，该报告的部分内容可以表示为：
Figure PCTCN2018071358-appb-000003
值得注意的是，其中rlf-Cause中的beamFailure对应波束失败指示，beamFailure RecoveryUnsuccesful对应波束失败恢复失败指示。本发明实施例包括其中一个参数增加为rlf-Cause的值的情况，也包括两个或以上的参数都增加为rlf-Cause的值的情况。
再例如，当波束失败或者波束恢复失败触发辅小区组无线链路失败的报告时，该报告的部分内容可以表示为：
Figure PCTCN2018071358-appb-000004
Figure PCTCN2018071358-appb-000005
值得注意的是，其中failureType-v15的beamFailure对应波束失败指示，beamFailure RecoveryUnsuccesful对应波束失败恢复失败指示。
再例如，当波束失败或者波束恢复失败不会触发辅小区组无线链路失败的报告 时，可以定义新的失败类型：
Figure PCTCN2018071358-appb-000006
值得注意的是，其中failureType中的beamFailure对应波束失败指示，beamFailure RecoveryUnsuccesful对应波束失败恢复失败指示。本发明实施例包括其中一个参数增加为failureType的值的情况，也包括两个或以上的参数都增加为failureType的值的情况。
再例如，该指示信息还可以作为新的UE上报信息，应用于主小区组和/或辅小区组。如果是主小区组，当网络设备发送的UE信息请求(UEInformationRequest)消息里包括波束beam-ReportReq或波束失败bf-ReportReq或波束失败恢复bfr-ReportReq上报请求时，如果有相应的报告，UE可以在UE信息响应(UEInformationResponse)消息里包括相应的报告。
如果是辅小区组，该上报信息例如可以按照至少如下之一处理：
UE先传递给服务主基站，由服务主基站确定该信息对应的基站，将收到的消息或组成的新消息传递给确定的基站；
UE直接传递给服务辅基站，由服务辅基站确定该信息对应的基站，如果该信息属于其他基站，则将收到的消息或其组成的新消息传递给确定的基站；
UE先通过服务主基站透传给服务辅基站，由服务辅基站确定该信息对应的基站，如果该信息属于其他基站，则将收到的消息或其组成的新消息传递给确定的基站。
值得注意的是，以上仅示意性说明了如何发送所述指示信息，但本发明不限于此，例如可以单独执行上述一种方式，也可以将上述的两个或以上的方式结合起来，或者 还可以使用其他的方式。
图6是本发明实施例的波束失败恢复的指示方法的另一示意图，示出了终端设备侧和网络设备侧的情况。如图6所示，波束失败恢复的指示方法600包括：
步骤601，终端设备确定其发生波束失败；
步骤602，终端设备确定预设的条件被满足；
在本实施例中，所述条件包括至少如下之一：波束失败恢复没有成功、发生波束失败、波束失败恢复成功但多个波束被用于发送波束失败恢复请求、接收到网络请求；但本发明不限于此。
例如，在辅基站发生波束失败的情况下，会直接触发终端设备上报。在主基站发生波束失败的情况下，如果不支持补充信令无线承载(SRB，Signaling Radio Bearer)，终端设备不能直接发送报告，而可以进行如下操作：终端设备先重选小区进行重建，并在重建过程中告知网络设备有可用的失败报告信息；基于该终端设备的指示，网络设备可以请求该终端设备上报相关信息；基于该网络设备的请求，该终端设备上报失败指示等信息。
步骤603，终端设备向网络设备发送指示信息。
步骤604，网络设备根据该指示信息进行移动鲁棒性优化；
例如，网络设备1接收到一个或多个终端设备上报的指示信息后，可以根据这些指示信息对用于确定候选波束的阈值candidateBeamThreshold进行调节。再例如，网络设备1接收到一个或多个终端设备上报的指示信息后，可以发送给网络设备2，由网络设备2根据这些指示信息对candidateBeamThreshold进行调节。
步骤605，终端设备接收网络设备发送的用于波束失败恢复的配置。
例如，终端设备1在步骤603中向网络设备1发送指示信息后，网络设备1可以在步骤604中进行移动鲁棒性优化，然后将用于波束失败恢复的专用配置发送给该终端设备1，该专用配置中包含有已经进行了调节的阈值candidateBeamThreshold。
再例如，终端设备1在步骤603中向网络设备1发送指示信息后，网络设备1可以在步骤604中进行移动鲁棒性优化，然后将用于波束失败恢复的专用配置发送给另一终端设备2，该专用配置中包含有已经进行了调节的阈值candidateBeamThreshold。
即，步骤603中发送指示信息的终端设备、和步骤605中接收配置的终端设备可以是同一设备，也可以是不同的设备；步骤603中接收指示信息的网络设备、步骤 604中进行移动鲁棒性优化的网络设备和步骤605中发送配置的网络设备可以是同一设备，也可以是不同的设备。本发明不对此进行限制。
值得注意的是，以上附图6仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图6的记载。
由上述实施例可知，终端设备向网络设备发送用于移动鲁棒性优化的指示信息；由此，终端设备能够根据网络设备的配置获得准确的波束测量结果，进而能够准确地确定候选波束，减少不成功的波束失败恢复。
