具体实施方式
为了能够更加详尽地了解本发明实施例的特点和技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在对本发明实施例进行详细说明之前，简要介绍相关技术中BFR的处理流程。
相关技术中，终端设备可通过随机接入的方式通知网络设备利用哪个下行Beam来发送随机接入响应(Random Access Response，RAR)，以恢复下行Beam。NR系统中的随机接入前导(random access preamble)是由per单边带(Single Slide Band，SSB)配置；终端设备首先通过对比参考信号接收功率(Reference Signal Receiving Power，RSRP)来选择满足阈值条件的SSB，或选择与SSB具有关联关系的信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)，并使用该SSB上对应的preamble以及物理随机接入信道(Physical Random Access Channel，PRACH)资源来发送消息1(Msg1)，理解为网络设备接收到preamble之后，便知道使用哪个SSB来反馈RAR。
相关技术中，基于BFR的随机接入过程包括以下几种方式：
1、基于竞争的随机接入(Contention Based Random Access，CFRA) BFR：无线资源控制(Radio Resource Control，RRC)配置了用于BFR的与SSB关联的CFRA资源，且有满足阈值的SSB。
2、基于非竞争的随机接入(Contention-Free Based Random Access，CBRA)BFR fallback from CFRA BFR，包括两种情况：
第一种是RRC配置了用于BFR的与SSB关联的CFRA资源，但是没有满足阈值的SSB；
第二种是Beam failure recovery Timer超时，UE只能使用CBRA BFR
3、CBRA BFR：RRC没有配置Beam Failure Recovery Config。
对于一个MAC实体，每当物理层上报一个波束失败实例(beam failure instance)，终端设备会为计数器BFI_COUNTER加1，并重启波束失败探测计时器(beam Failure Detection Timer)；若在beam Failure Detection Timer运行期间，BFI_COUNTER达到最大值，则认为beam failure，并发起随机接入流程。对于CFRA BFR，网络设备会配置BFR Config IE，终端设备使用该IE里的参数进行随机接入。对于CBRA BFR，如果配置了BFR Config IE，则使用该IE里配置的power Ramping Step,preamble Received Target Power,preamble Trans Max进行随机接入；若没有，则使用普通RACH过程，若该随机接入过程成功，则认为该BFR过程成功。
本申请人在实施BFR过程中发现，基于随机接入过程完成的BFR需要判断网络设备是否配置了BFR Config，在网络设备没有配置BFR Config时，需要对Beam进行筛选，根据筛选结果进行普通的随机接入，以通知网络设备利用哪个Beam进行BFR；在网络设备配置BFR Config时，使用该IE里配置的参数进行随机接入，以通知网络设备利用哪个Beam进行BFR；无论网络设备是否配置BFR Config，随机接入的过程需要的时延都比较长。
本发明实施例提供的应用于终端设备的指示BFR的方法的可选处理流程一，如图1所示，包括以下步骤：
步骤S101，终端设备发送MAC CE，所述MAC CE指示用于网络设备发送反馈消息的Beam对应的Beam Index。
在一些实施例中，物理层向终端设备上报波束失败实例(Beam Failure Instance)，终端设备在判断满足触发BFR条件时，向网络设备发送用于BFR的MAC CE。
这里，终端设备发送MAC CE之前，需要判断是否能够发送MAC CE；在具体实施时，可通过判断是否有可用的资源来发送MAC CE；在判断有可用的资源时，终端设备发送MAC CE。其中，终端设备发送MAC CE所使用的资源是基于调度或者使用半静态配置的；所述Beam Index可以通过SSB Index或者CSI-RS Index来指示
由于终端设备发送的MAC CE指示用于网络设备发送反馈消息的Beam对应的Beam Index，因此，终端设备需要预先判断满足阈值条件的下行Beam，所述MAC CE指示的发送反馈消息的Beam为满足阈值条件的下行Beam。其中，满足阈值条件的下行Beam为：在候选波束列表(Candidate Beam RS list)中CSI-RS的参考信号接收功率CSI-RSRP在参考信号接收功率阈值以上的Beam；或者在Candidate Beam RS list中单边带的同步信号接收功率SS-RSRP在参考信号接收功率阈值以上的Beam。
本发明实施例提供的应用于终端设备的指示BFR的方法的可选处理流程二与上述可选处理流程一相似，如图2所示，不同之处在于，在步骤S101之后，还包括：
步骤S102，终端设备接收反馈消息。
在一些实施例中，所述反馈消息由网络设备基于所述MAC CE指示的Beam Index对应的Beam发送。
步骤S103，终端设备基于反馈消息判断BFR是否成功。
在一些实施例中，所述反馈消息为下行调度信息；终端设备在接收 到网络设备发送的下行调度信息时，判断BFR成功；终端设备在未接收到网络设备发送的下行调度信息时，判断BFR失败。
在具体实施时，终端设备发送所述MAC CE之后，启动定时器；若在所述定时器运行期间，接收到所述网络设备发送的下行调度信息，判断BFR成功；若在所述定时器运行期间，没有接收到所述网络设备发送的下行调度信息，判断BFR失败。
本发明实施例中，下行调度信息可以基于小区-无线网络临时标识(Cell-Radio Network Tempory Identity，C-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)发送；当然，下行调度信息也可以基于其他方式加扰的PDCCH发送。
步骤S104，终端设备在判断BFR失败之后，重新发送MAC CE或者终端设备在判断BFR失败之后，进入随机接入流程，以进行BFR。
本发明实施例中，终端设备在判断BFR失败之后，可通过判断是否有可用的资源来通过重新发送MAC CE进行BFR或者通过随机接入流程进行BFR。在判断通过重新发送MAC CE进行BFR时，终端设备重新发送MAC CE。在判断通过随机接入流程进行BFR时，终端设备进入随机接入流程。
本发明实施例提供的应用于网络设备的指示BFR的方法的可选处理流程一，如图3所示，包括以下步骤：
步骤S201，网络设备接收终端设备发送的MAC CE。
这里，所述MAC CE指示用于网络设备发送反馈消息的Beam对应的Beam Index。
步骤S202，网络设备基于所述MAC CE指示的Beam Index对应的Beam向终端设备发送反馈消息。
这里，反馈消息用于终端设备判断BFR是否成功；反馈消息为下行调度或PDCCH，所述PDCCH可以为利用C-RNTI加扰的PDCCH。
基于上述指示BFR的方法，本发明实施例还提供一种终端设备，终端设备的组成结构示意图，如图4所示，终端设备400包括：
第一发送单元401，配置为在满足触发波束失败修复BFR条件时，发送MAC CE；所述MAC CE指示用于网络设备发送反馈消息的Beam对应的Beam Index。

在一些实施例中，终端设备400还包括：判断单元403，配置为基于所述反馈消息，判断BFR是否成功。
在一些实施例中，判断单元403，配置为在所述第一发送单元发送所述MAC CE之后，启动定时器；若在所述定时器运行期间，接收到所述网络设备发送的下行调度信息，判断BFR成功；若在所述定时器运行期间，没有接收到所述网络设备发送的下行调度信息，判断BFR失败。
在一些实施例中，判断单元403，配置为在第一接收单元402接收到网络设备发送的下行调度信息时，判断BFR成功；在所述第一接收单元402未接收到网络设备发送的下行调度信息时，判断BFR失败。
在一些实施例中，第一发送单元401，还配置为所述判断单元判断BFR失败之后，重新发送MAC CE，所述MAC CE指示用于网络设备发送反馈消息的Beam对应的Beam Index。
在一些实施例中，判断单元403，还配置为判断满足阈值条件的下行Beam；所述MAC CE指示的Beam Index对应的Beam为满足阈值条件的下行Beam。
在一些实施例中，第一发送单元401发送MAC CE所使用的资源是基于动态调度或使用半静态资源配置。
在一些实施例中，所述第一发送单元401，还配置为发送所述MAC CE之前，判断是否能够发送MAC CE。
在具体实施时，可通过判断是否有可用的资源来发送MAC CE；在判断有可用的资源时，所述第一发送单元401发送MAC CE。
基于上述指示BFR的方法，本发明实施例还提供一种网络设备，网络设备的组成结构示意图，如图5所示，网络设备500包括：
第二接收单元501，配置为接收终端设备发送的MAC CE；
第二发送单元502，配置为基于所述MAC CE指示的Beam Index对应的Beam向所述终端设备发送反馈消息；所述反馈消息用于所述终端设备判断BFR是否成功。

步骤S601，终端设备向网络设备发送MAC CE。
这里，所述MAC CE指示用于网络设备发送反馈消息的Beam对应的Beam Index。
步骤S602，网络设备根据MAC CE指示的Beam Index对应的Beam向终端设备发送反馈消息。
步骤S603，终端设备根据反馈消息判断BFR是否成功。
在一些实施例中，终端设备在接收到网络设备发送的下行调度信息时，判断BFR成功；终端设备在未接收到网络设备发送的下行调度信息时，判断BFR失败。
在具体实施时，终端设备发送所述MAC CE之后，启动定时器；若在所述定时器运行期间，接收到所述网络设备发送的下行调度，判断BFR成功；若在所述定时器运行期间，没有接收到所述网络设备发送的下行调度，判断BFR失败。
