图2为本申请实施例提供的BFR实现方法的第一示意性流程图。如图2所示，包括以下具体实现方式。
在201中，终端设备确定满足BFR触发条件。
在202中，终端设备向网络设备发送SR，以便通过SR实现BFR。
当物理层上报一个波束失败事件(beam failure instance)时，媒体接入控制(MAC，Media Access Control)层收到该beam failure instance即启动或重启一个波束失败检测定时器(BeamFailureDetectionTimer)，并为计数器BFI_COUNTER加1，初始，计数器BFI_COUNTER的取值为0，之后，物理层每上报一个beam failure instance，则可将计数器BFI_COUNTER加1，若在BeamFailureDetectionTimer运行期间(即定时器超时之前)计数器BFI_COUNTER的取值达到设定的最大值，则可认为beam failure，从而满足BFR触发条件。
终端设备一旦确定满足BFR触发条件，则可向网络设备发送SR，以便通过SR实现BFR。
可选地，终端设备在向网络设备发送SR之前，还可先确定当前是否符合SR发送条件，若是，则可向网络设备发送SR，否则，可采用现有的随机接入方式实现BFR。
其中，符合SR发送条件可以是指：存在可用于发送SR的资源。也就是说，如果存在可用于发送SR的资源，终端设备则可向网络设备发送SR，以便通过SR实现BFR，如果不存在可用于发送SR的资源，终端设备则可采用随机接入的方式实现BFR。
若采用随机接入的方式实现BFR，那么终端设备可发起随机接入流程。
NR的随机接入过程根据业务触发方式的不同，可将随机接入分为基于竞争的随机接入(CBRA，Contention-Based Random Access)以及基于非竞争的随机接入(CFRA，Contention-Free Random Access)。
对于BFR来说，终端设备需要先判断网络侧是否配置了用于BFR的资源或者是否有SSB满足阈值来选择是进行CFRA或者CBRA。对于CFRA BFR，网络设备会配置beamFailureRecoveryConfigIE，终端设备可使用该IE中的参数进行随机接入。对于CBRA BFR，可能配置了beamFailureRecoveryConfigIE，也可能未配置，若有配置，那么可使用该IE中的参数进行随机接入，若未配置，可执行通用随机接入信道过程(common RACH procedure)。若随机接入过程成功，则认为BFR成功。
如前所述，若存在可用于发送SR的资源，那么终端设备可向网络设备发送SR，发送SR所使用的资源可包括：动态调度的资源、半静态配置资源或为SR配置的特定资源等。
SR中可通过显式或隐式的方式携带有终端设备指示给网络设备的下行beam的beam信息，以便网络设备通过该下行beam向终端设备发送反馈信息。
显式的方式可以是指在SR中携带终端设备指示给网络设备的下行beam的波束索引(beam index)信息。隐式的方式可以是指根据预先配置的上行调度请求配置信息(SR config)与beam index信息之间的对应关系，利用SR config指示终端设备指示给网络设备的下行beam的beam index信息。比如，可配置对应于逻辑信道1的SR config对应于beam index 1，那么当SR config为对应于逻辑信道1的SR config时，则可确定终端设备指示给网络设备的下行beam为beam index 1对应的beam。也可以是为不同的beam预配置不同的SR config等。
另外，终端设备在发送SR之前，还可先从所配置的候选列表(candidateBeamRSList)选出一个参考信号接收功率(RSRP，Reference Signal Receiving Power)大于预定阈值的同步信号块(SSB，Synchronization Signal Block)或信道状态信息参考信号(CSI-RS，Channel-State Information Reference Signal)，将选出的SSB或CSI-RS对应的beam作为指示给网络设备的下行beam。
若candidateBeamRSList中包含SSB信息，那么则可从中选出一个RSRP大于预定阈值的SSB，将该SSB对应的beam作为指示给网络设备的下行beam。若candidateBeamRSList中不包含SSB信息，但包含CSI-RS信息，那么可从中选出一个RSRP大于预定阈值的CSI-RS，将该CSI-RS对应的beam作为指示给网络设备的下行beam。
如果大于预定阈值的SSB或CSI-RS数大于一，那么可从中随机选出一个SSB或CSI-RS，或者，也可以选出RSRP最好的SSB或CSI-RS等，具体实现方式不限。
网络设备接收到终端设备发送的SR之后，可通过其中指示的下行beam向终端设备发送反馈信息，如下行调度。
终端设备在发送SR之后，可进一步确定BFR是否成功，若否，可重新发送SR。
比如，在发送SR之后，终端设备接收到网络设备通过所指示的下行beam发送来的反馈信息，那么则可确定BFR成功，反之，可重新发送SR。
再比如，在发送SR之后，终端设备可启动一个定时器，若在定时器超时之前(即定时器运行期间)接收到网络设备通过所指示的下行beam发送来的反馈信息，那么则可确定BFR成功，反之，可重新发送SR。
所述反馈信息可为下行调度，如小区无线网络临时标识(C-RNTI，Cell Radio Network Temporary Identifier)加扰的物理下行控制信道(PDCCH，Physical Downlink Control Channel)。
可选地，终端设备在向网络设备重新发送SR之前，还可先确定当前是否符合 SR发送条件，若是，则可向网络设备发送SR，否则，可采用现有的随机接入方式实现BFR。
以上主要是从终端设备一侧对本申请所述方案进行说明，对于网络设备一侧，如图3所示，图3为本申请实施例提供的BFR实现方法的第二示意性流程图，包括以下具体实现方式。
在301中，网络设备获取来自终端设备的SR，所述SR为终端设备确定满足BFR触发条件时，向网络设备发送的SR。
SR中可通过显式或隐式的方式携带有终端设备指示给网络设备的下行beam的beam信息。
在302中，网络设备通过SR中指示的下行beam向终端设备发送反馈信息。
所述反馈信息可为下行调度，如C-RNTI加扰的PDCCH等。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其它实施例中的相关描述。
总之，采用本申请方法实施例所述方案，可基于SR来实现BFR，从而相比于随机接入方式减少了时延，达到了快速修复beam的目的。
以上是关于方法实施例的介绍，以下通过装置实施例，对本申请所述方案进行进一步说明。
图4为本申请实施例提供的BFR实现装置的第一示意性结构图。如图4所示，包括：确定单元401以及发送单元402。
确定单元401，用于确定是否满足BFR触发条件，若是，则通知发送单元402执行自身功能。
发送单元402，用于向网络设备发送SR，以便通过SR实现BFR。
当物理层上报一个beam failure instance时，MAC层收到该beam failure instance即启动或重启一个BeamFailureDetectionTimer，并为计数器BFI_COUNTER加1，初始，计数器BFI_COUNTER的取值为0，之后，物理层每上报一个beam failure instance，则可将计数器BFI_COUNTER加1，若在BeamFailureDetectionTimer运行期间(即定时器超时之前)计数器BFI_COUNTER的取值达到设定的最大值，则可认为beam failure，从而满足BFR触发条件。
确定单元401一旦确定满足BFR触发条件，则可通知发送单元402，相应地，发送单元402可向网络设备发送SR，以便通过SR实现BFR。
SR发送使用的资源可包括：动态调度的资源、半静态配置资源或为SR配置的 特定资源等。
SR中可通过显式或隐式的方式携带有波束失败恢复实现装置指示给网络设备的下行beam的beam信息，以便网络设备通过下行beam向波束失败恢复实现装置发送反馈信息。
其中，显式的方式可以是指在SR中携带下行beam的beam index信息，隐式的方式可以是指根据预先配置的SR config与beam index信息之间的对应关系，利用SR config指示指示给网络设备的下行beam的beam index信息。
另外，发送单元402在发送SR之前，可先从所配置的候选列表选出一个RSRP大于预定阈值的SSB或CSI-RS，将选出的SSB或CSI-RS对应的beam作为指示给网络设备的下行beam。
发送SR之后，发送单元402还可进一步确定BFR是否成功，若否，则重新发送SR。
比如，在发送SR之后，若接收到网络设备通过所指示的下行beam发送来的反馈信息，那么则可确定BFR成功，反之，可重新发送SR。
再比如，在发送SR之后，可启动一个定时器，若在定时器超时之前接收到网络设备通过所指示的下行beam发送来的反馈信息，那么则可确定BFR成功，反之，可重新发送SR。
另外，发送单元402在每次发送SR之前，还可先确定当前是否符合SR发送条件，若是，则向网络设备发送SR，否则，可采用随机接入的方式实现BFR。
符合SR发送条件可以只是：存在可用于发送SR的资源。

获取单元501，用于获取来自终端设备的SR，所述SR为终端设备确定满足BFR触发条件时，向波束失败恢复实现装置发送的SR，以便通过所述SR实现BFR。
SR中可通过显式或隐式的方式携带有终端设备指示给波束失败恢复实现装置的下行beam的beam信息。
相应地，波束失败恢复实现装置中可进一步包括：反馈单元502，用于通过所指示的下行beam向终端设备发送反馈信息。
