应理解，本申请中的通信设备的全部或部分功能也可以通过在硬件上运行的软件功能来实现，或者通过平台(例如云平台)上实例化的虚拟化功能来实现。
波束失败事件检测过程
目前，若终端设备的物理层检测到物理下行控制信道(physical downlink control channel，PDCCH)对应的全部波束的误块率(block error rate)BLER都低于规定的门限，则记为一次波束失败样本(beam failure instance，BFI)，此时，终端设备的物理层可以给媒体接入控制(media access control，MAC)层上报一次BFI。通常，物理层需要周期性地向MAC层上报BFI，如果某次没有上报，则认为没有BFI。
相应地，MAC层维护相关的波束失败检测定时器(beam failure detection timer)和波束失败计数器(BFI_COUNTER)。为了保证波束失败检测的可靠性，每当MAC层收到一次BFI上报，则启动或重启波束失败检测定时器，同时波束失败计数器取值加1，若波束失败检测定时器超时，终端设备会将波束失败计数器重置(即取值为0)。若在波束失败检测定时器运行期间波束失败计数器取值达到了规定的最大值，则终端设备的MAC层会判断认为发生了波束失败(beam failure)事件(例如，下文介绍的第一波束失败事件和/或第二波束失败事件)。
波束失败恢复操作
一方面，若终端设备的MAC层检测到发生了波束失败事件，并且在发生波束失败事件之前终端设备已经获取了网络设备配置的波束失败恢复配置，则终端设备按照如下规则执行波束失败恢复操作。
假设终端设备获得波束的参考信号接收功率(reference signal receiving power，RSRP)测量结果，如果网络设备配置的波束失败恢复配置所配置的全部参考信号对应的波束的RSRP测量结果中存在至少一个参考信号对应的波束的RSRP测量结果大于波束失败恢复配置指示的第一阈值，则终端设备可以选择前述波束的RSRP测量结果大于第一阈值的波束所关联的非竞争随机接入资源发起随机接入过程。在发起非竞争随机接入过程后，如果成功接收到网络设备的响应，则终端设备认为波束失败恢复成功。
相反地，如果网络设备配置的波束失败恢复配置所配置的全部参考信号对应的波束的RSRP测量结果均小于或等于波束失败恢复配置指示的第一阈值，则终端设备基于终端设备实现选择一个波束并发起基于竞争随机接入资源的随机接入过程。在发起竞争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功；
另一方面，若终端设备的MAC层检测到发生了波束失败事件，并且在发生波束失败事件之前终端设备没有获取网络设备配置的波束失败恢复配置，则按照如下规则执行波束失败恢复操作。
终端设备基于终端设备的实现选择一个波束并发起基于竞争随机接入资源的随机接入过程，发起竞 争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功。
应理解，在本申请实施例中，波束的测量结果含义等同于波束对应的波束级(beam level)测量结果。也即是说，本申请实施例中并不区分波束的测量结果和波束对应的波束级测量结果含义。另外，测量结果对应的测量量可以为RSRP。
如上文所述，传统的波束失败恢复机制是在非AI功能下引入的，在引入之初并没有考虑AI技术可能带来的额外影响。目前，一些讨论主要围绕基于AI的波束管理功能，并未定义在波束失败场景下基于AI的波束失败恢复机制该如何操作，如何利用AI技术实现更加绿色节能的波束失败恢复机制是一个值得考虑的方向。
因此，针对上述问题，本申请实施例中引入了与波束失败恢复关联的第一操作，有利于实现更加绿色节能的波束失败恢复机制。下文结合图2介绍本申请实施例的无线通信的方法。图2所示的方法包括步骤S210。
在步骤S210中，若发生第一事件，终端设备基于第一参考信号集合执行与波束失败恢复关联的第一操作。
在一些实现方式中，第一参考信号集合通过波束失败恢复配置确定，其中，波束失败恢复配置可以是第一网络设备为终端设备配置的(比如通过专用信令配置)，例如，参见图2中步骤S220。
在本申请实施例中，对第一参考信号集合中指示的参考信号类型不作限定。例如，第一参考信号集合中指示的参考信号可以包括同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block或SSB)或者信道状态信息参考信号(channel state information reference signal，CSI-RS)。当然，在本申请实施例中，第一参考信号集中指示的参考信号还可以是未来通信系统中引入的其他参考信号。
在一些实现方式中，第一事件包括终端设备检测到第一波束失败事件，或终端设备触发了连接重建立过程。在一些场景中，第一事件可以是预设的事件或者说是协议中约定的事件，因此，第一事件又称为“预设事件”。
在一些实现方式中，第一事件包括终端设备检测到第一波束失败事件，在第一事件发生之前，终端设备可能正在执行基于AI功能的波束管理功能，或者正在执行基于非AI功能的波束管理功能，本申请实施例对此不做限定。
如上文所述，第一事件可以包含两种实现方式，针对不同的实现方式，第一操作也不同。因此，下文结合场景一和场景二分别进行介绍。
场景一：第一事件包括终端设备检测到第一波束失败事件，或者说，第一事件包括第一波束失败事件。
在方案1中，第一参考信号集合通过波束失败恢复配置中包含的第一参数指示，且通过默认方式约定第一参考信号集合中指示的全部参考信号均为需要终端设备实际测量的参考信号。
在一些实现方式中，上述默认方式约定例如可以包括协议约定。
在一些实现方式中，第一参数用于指示以下一种或多种：第一参考信号集合中指示的参考信号所关联的波束的标识信息；第一参考信号集合中指示的参考信号所关联的波束关联的非竞争随机接入资源。
例如，第一参数用于指示第一参考信号集合中指示的参考信号所关联的波束的标识信息。又例如，第一参数用于指示第一参考信号集合中指示的参考信号所关联的波束关联的非竞争随机接入资源。又例如，第一参数用于指示第一参考信号集合中指示的参考信号所关联的波束的标识信息以及对应波束关联的非竞争随机接入资源。
在一些实现方式中，第一参考信号集合中指示的参考信号所关联的波束的标识信息可以包括一个或多个波束的标识信息。其中，波束的标识信息例如可以包括SSB波束标识或者CSI-RS波束标识。
在一些实现方式中，第一参考信号集合中指示的参考信号所关联的波束可以包括一个或多个波束，相应地，第一参数还用于指示一个或多个波束关联的非竞争随机接入资源。
在一些实现方式中，若第一参考信号集合中指示的参考信号所关联的波束中第一波束的测量结果大于第一阈值，则第一操作包括基于第一波束关联的第一非竞争随机接入资源发起随机接入过程，其中，第一非竞争随机接入资源通过第一参数指示；和/或若第一参考信号集合中指示的参考信号所关联的任意一个波束的测量结果均小于或等于第一阈值，则第一操作包括基于竞争随机接入资源发起随机接入过程。
在一些实现方式中，第一阈值可以是通过波束失败恢复配置指示，详细可以参见前文波束失败恢复操作中的第一阈值。
在一些实现方式中，上述第一参考信号集合中指示的参考信号所关联的波束中可能包含一个或多个波束的测量结果大于第一阈值，此时，测量结果大于第一阈值的波束可以包括第一波束。也即是说，第 一参考信号集合中指示的参考信号所关联的波束中第一波束的测量结果大于第一阈值，可以理解为第一参考信号集合中指示的参考信号所关联的波束中存在一个或多个波束的测量结果大于第一阈值。
在一些实现方式中，上述第一参考信号集合中指示的参考信号所关联的任意一个波束的测量结果均小于或等于第一阈值，或者说，上述第一参考信号集合中指示的全部参考信号所关联的波束的测量结果均小于或等于第一阈值。
在本申请实施例中，对第一波束的测量结果对应的测量量不作限定。在一些实现方式中，测量结果对应的测量量可以为RSRP，又称“RSRP测量结果”。例如，RSRP测量结果可以为L1-RSRP测量结果。在另一些实现方式中，测量结果对应的测量量可以为信号与干扰和噪声的比值(signal to interference plus noise ratio，SINR)，又称“SINR测量结果”。例如，SINR测量结果可以为L1-SINR测量结果。在另一些实现方式中，测量结果对应的测量量可以为参考信号接收质量(reference signal receiving quality，RSRQ)，又称“RSRQ测量结果”。例如，RSRQ测量结果可以为L1-RSRQ测量结果。
在方案1中，不论是基于非AI的波束管理功能还是基于AI的波束管理功能，波束失败后终端设备的行为保持一致，有利于简化波束失败后终端设备的行为，即：不用为基于AI的波束管理功能单独引入一套新的波束失败恢复操作机制。
例如，第一网络设备向终端设备发送的波束失败恢复配置用于配置：第一阈值，SSB波束标识1以及SSB波束标识1关联的非竞争随机接入资源，SSB波束2以及SSB波束标识2关联的非竞争随机接入资源，SSB波束3以及SSB波束标识3关联的非竞争随机接入资源，其中，SSB波束标识1关联的参考信号、SSB波束标识2关联的参考信号以及SSB波束标识3关联的参考信号为终端设备需要实际测量的参考信号，那么，在发生波束失败事件后，终端设备可以基于实际测量过程获得SSB波束标识1关联的RSRP测量结果、SSB波束标识2关联的RSRP测量结果以及SSB波束标识3关联的RSRP测量结果。
相应地，如果这3个波束中部分或全部波束的RSRP测量结果大于第一阈值，则终端设备选择RSRP测量结果大于第一阈值的波束关联的非竞争随机接入资源发起随机接入过程。发起非竞争随机接入过程后，如果成功接收到第一网络设备的响应，则终端设备认为波束失败恢复成功。
相反地，如果这3个波束中全部波束的RSRP测量结果均小于或等于第一阈值，则终端设备选择一个波束并发起基于竞争随机接入资源的随机接入过程。发起竞争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功。
需要说明的是，终端设备选择波束发起基于竞争的随机接入过程中，对终端设备选择波束的方式不作限定。选择波束的方式可以取决于终端设备的具体实现。
在方案2中，第一参考信号集合通过波束失败恢复配置中包含的第一参数指示。
在方案2配置方式1中，第一参数用于指示第一部分参考信号，此时，第一部分参考信号组成的集合为第一参考信号集合，其中，第一部分参考信号为需要终端设备实际测量的参考信号。也即是说，配置方式1下，第一参考信号集合中指示的全部参考信号均为需要终端设备实际测量的参考信号。
在一些实现方式中，第一参数用于指示以下一种或多种：第一部分参考信号所关联的波束的标识信息，第一部分参考信号所关联的波束关联的非竞争随机接入资源。
例如，第一参数用于指示第一部分参考信号所关联的波束的标识信息。又例如，第一参数用于指示第一部分参考信号所关联的波束关联的非竞争随机接入资源。又例如，第一参数用于指示第一部分参考信号所关联的波束的标识信息以及对应波束关联的非竞争随机接入资源。
在一些实现方式中，第一部分参考信号所关联的波束的标识信息可以包括一个或多个波束的标识信息。其中，波束的标识信息例如可以包括SSB波束标识或者CSI-RS波束标识。
在一些实现方式中，第一部分参考信号所关联的波束可以包括一个或多个波束，相应地，第一参数还用于指示一个或多个波束关联的非竞争随机接入资源。
在一些实现方式中，若第一部分参考信号中指示的参考信号所关联的波束中第一波束的测量结果大于第一阈值，则第一操作包括基于第一波束关联的第一非竞争随机接入资源发起随机接入过程；和/或若第一部分参考信号中指示的参考信号所关联的任意一个波束的测量结果均小于或等于第一阈值，则第一操作包括基于竞争随机接入资源发起随机接入过程。
在一些实现方式中，上述第一部分参考信号中指示的参考信号所关联的波束中可能包含一个或多个波束的测量结果大于第一阈值，此时，测量结果大于第一阈值的波束可以包括第一波束。也即是说，第一部分参考信号中指示的参考信号所关联的波束中第一波束的测量结果大于第一阈值，可以理解为第一部分参考信号中指示的参考信号所关联的波束中存在一个或多个波束的测量结果大于第一阈值。
在一些实现方式中，上述第一部分参考信号中指示的参考信号所关联的任意一个波束的测量结果均小于或等于第一阈值，或者说，上述第一部分参考信号中指示的全部参考信号所关联的波束的测量结果 均小于或等于第一阈值。
在本申请实施例中，对第一波束的测量结果不作限定。在一些实现方式中，测量结果对应的测量量可以为RSRP，又称“RSRP测量结果”。例如，RSRP测量结果可以为L1-RSRP测量结果。在另一些实现方式中，测量结果对应的测量量可以为SINR，又称“SINR测量结果”。例如，SINR测量结果可以为L1-SINR测量结果。在另一些实现方式中，测量结果对应的测量量可以为RSRQ，又称“RSRQ测量结果”。例如，RSRQ测量结果可以为L1-RSRQ测量结果。
在方案2配置方式1下，不论是基于非AI的波束管理功能还是基于AI的波束管理功能，波束失败后终端设备的行为保持一致，有利于简化波束失败后终端设备的行为，即：不用为基于AI的波束管理功能单独引入一套新的波束失败恢复操作机制。
在方案2配置方式2中，第一参数用于指示第一部分参考信号以及第二部分参考信号，此时，第一部分参考信号以及第二部分参考信号组成的集合为第一参考信号集合，其中，终端设备需要实际测量第一部分参考信号，终端设备不需要实际测量第二部分参考信号。
在一些实现方式中，第二部分参考信号的测量结果可以基于AI的波束预测功能确定。
在一些场景中，第一部分参考信号关联的波束可以属于集合B(Set B)，第二部分参考信号关联的波束可以属于集合A(Set A)，基于Set B中波束的测量结果(即实际测量结果)可以预测得到Set A中全部或者部分波束的测量结果。
在方案2配置方式2中，第一网络设备配置的第一参考信号集合中不全都是终端设备可实际测量的参考信号，换句话说，在一次配置过程中，第一网络设备配置给终端设备的波束失败恢复配置涉及的全部参考信号中的第一部分参考信号为终端设备可实际测量的参考信号，而第二部分参考信号为终端设备不需要实际测量的参考信号。如上文所述，第二部分参考信号可以是基于AI功能预测测量结果的参考信号，因此，实际上第一网络设备不发送第二部分参考信号，或者第一网络设备按照比发送第一部分参考信号更长的周期发送第二部分参考信号，都可以节约第一网络设备发送部分参考信号的功耗。对于终端设备而言，也不用实际测量这部分参考信号，一定程度也可以节省能耗。
在本申请实施例中，对第一网络设备不发送第二部分参考信号的场景不作限定。例如，在没有开启AI波束预测功能监测的情况下，第一网络设备不发送第二部分参考信号。
在本申请实施例中，对第一网络设备按照比发送第一部分参考信号更长的周期发送第二部分参考信号所适用的场景不作限定。例如，在用于AI波束预测功能监测目的的场景下，第一部分参考信号发送周期为80ms，而第二部分参考信号发送周期为480ms。通常，除了性能监测任务导致的周期性实际测量第二部分参考信号场景外，第二部分参考信号的测量结果都是通过AI功能预测过程获得的。
另一方面，相比基于非AI的波束失败恢复功能，第一网络设备可以为基于AI的波束失败恢复功能配置更少的需要终端设备实际测量的参考信号，但由于基于AI的波束失败恢复功能引入了基于AI的波束预测功能，因此，基于AI的波束失败恢复功能可以在测量较少参考信号的条件下实现不错的波束失败恢复功能，体现了AI技术的优势。
如上文所述，第一参数用于指示第一部分参考信号以及第二部分参考信号，在一些实现方式中，第一参数用于指示以下一种或多种：第一部分参考信号所关联的波束的标识信息；第一部分参考信号所关联的波束关联的非竞争随机接入资源；第二部分参考信号所关联的波束的标识信息；第二部分参考信号所关联的波束关联的非竞争随机接入资源，其中，关于波束的标识信息的介绍可以参见上文。
在本申请实施例中，第一参数用于指示上述信息中的某一种。例如，第一参数用于指示第一部分参考信号所关联的波束的标识信息。又例如，第一参数用于指示第一部分参考信号所关联的波束关联的非竞争随机接入资源。又例如，第一参数用于指示第二部分参考信号所关联的波束的标识信息。又例如，第一参数用于指示第二部分参考信号所关联的波束关联的非竞争随机接入资源。
在本申请实施例中，第一参数用于指示上述信息中任意几种信息。例如，第一参数用于指示：第一部分参考信号所关联的波束的标识信息；第一部分参考信号所关联的波束关联的非竞争随机接入资源；第二部分参考信号所关联的波束的标识信息；第二部分参考信号所关联的波束关联的非竞争随机接入资源。又例如，第一参数用于指示：第一部分参考信号所关联的波束的标识信息；第一部分参考信号所关联的波束关联的非竞争随机接入资源。又例如，第一参数用于指示：第二部分参考信号所关联的波束的标识信息；第二部分参考信号所关联的波束关联的非竞争随机接入资源。又例如，第一参数用于指示：第一部分参考信号所关联的波束的标识信息；第一部分参考信号所关联的波束关联的非竞争随机接入资源；第二部分参考信号所关联的波束的标识信息。又例如，第一参数用于指示：第一部分参考信号所关联的波束的标识信息；第一部分参考信号所关联的波束关联的非竞争随机接入资源；第二部分参考信号所关联的波束关联的非竞争随机接入资源。在本申请实施例中对第一参数所指示的上述信息的组合方式不作限定。
如上文所述，若第一参数用于指示第一部分参考信号以及第二部分参考信号，在一些实现方式中，第一操作包括基于以下一种或多种信息，确定不需要终端设备实际测量的参考信号中部分参考信号或全部参考信号所关联的波束的测量结果：需要终端设备实际测量的参考信号中全部参考信号所关联的波束的测量结果；需要终端设备实际测量的参考信号中部分参考信号所关联的波束的测量结果；需要终端设备实际测量的参考信号中全部参考信号所关联的波束的标识信息；需要终端设备实际测量的参考信号中部分参考信号所关联的波束的标识信息；不需要终端设备实际测量的参考信号所关联的波束的标识信息；其中，需要终端设备实际测量的参考信号包括第一部分参考信号，不需要终端设备实际测量的参考信号包括第二部分参考信号。
在本申请实施例中，对上述需要终端设备实际测量的参考信号不作限定。在一些实现方式中，需要终端设备实际测量的参考信号包括第一部分参考信号，可以理解为需要终端设备实际测量的参考信号为第一部分参考信号。
例如，第一网络设备配置的需要终端设备实际测量的参考信号即为基于AI的波束失败恢复功能中需要终端设备实际测量的参考信号(即第一部分参考信号)。假设第一网络设备为终端设备配置的需要终端设备实际测量的参考信号包含SSB波束标识1对应的参考信号，SSB波束标识3对应的参考信号，以及通过SSB波束标识5对应的参考信号，此时，第一部分参考信号包含的参考信号即为SSB波束标识1对应的参考信号，SSB波束标识3对应的参考信号，以及通过SSB波束标识5对应的参考信号。因此，第一部分参考信号是需要终端设备实际测量的参考信号中的全部参考信号。
在另一些实现方式中，需要终端设备实际测量的参考信号包括第一部分参考信号，可以理解为第一部分参考信号为第一网络设备为终端设备配置的需要终端设备实际测量的参考信号中的部分参考信号。
例如，第一网络设备配置的需要终端设备实际测量的参考信号包括基于非AI的波束失败恢复功能(即传统的波束失败恢复功能)中需要终端设备实际测量的参考信号，而基于AI的波束失败恢复功能(即第一部分参考信号)中需要终端设备实际测量的参考信号可以是基于非AI的波束失败恢复功能中需要终端设备实际测量的参考信号中的部分参考信号。
又例如，第一网络设备配置的需要终端设备实际测量的参考信号包括层3(或层1)测量配置中指示的需要终端设备实际测量的参考信号，而基于AI的波束失败恢复功能(即第一部分参考信号)中需要终端设备实际测量的参考信号可以是层3(或层1)测量配置中指示的需要终端设备实际测量的参考信号中的部分参考信号。

需要说明的是，上文以示例1～示例6为例介绍了本申请实施例中的第一操作。在本申请实施例中，对第一操作的实现方式不作限定，第一操作还可以有其他的实现方式。
例如，上述需要终端设备实际测量的参考信号中部分参考信号可以为第一部分参考信号，相应地，示例6中的第一操作可以理解为：基于第一部分参考信号所关联的波束的测量结果，第一部分参考信号所关联的波束的标识信息，第二部分参考信号所关联的波束的标识信息，确定第二部分参考信号所关联的波束的测量结果。示例3中的第一操作可以理解为：基于第一部分参考信号所关联的波束的测量结果，确定第二部分参考信号所关联的波束的测量结果。
又例如，第一操作还可以包括：基于第一部分参考信号所关联的波束的测量结果，第二部分参考信号所关联的波束的标识信息，确定第二部分参考信号所关联的波束的测量结果。
又例如，第一操作还可以包括：基于第一部分参考信号所关联的波束的测量结果，不需要终端设备实际测量的参考信号所关联的波束的标识信息，确定不需要终端设备实际测量的参考信号所关联的波束的测量结果。
又例如，第一操作还可以包括：基于第一部分参考信号所关联的波束的测量结果，第一部分参考信号所关联的波束的标识信息，不需要终端设备实际测量的参考信号所关联的波束的标识信息，确定不需要终端设备实际测量的参考信号所关联的波束的测量结果。
在一些实现方式中，若终端设备获取了波束失败恢复配置所配置的全部参考信号对应的波束的测量结果，即第一部分参考信号对应的波束的测量结果以及第二部分参考信号对应的波束的测量结果，则上述方法还包括：终端设备执行以下一种或多种操作。
例如，终端设备执行：如果第一部分参考信号对应的波束的测量结果以及第二部分参考信号对应的波束的测量结果中存在至少一个参考信号对应的波束的测量结果大于第一阈值，则终端设备选择测量结果大于第一阈值的波束关联的非竞争随机接入资源发起随机接入过程。在发起非竞争随机接入过程后，如果成功接收到第一网络设备的响应，则终端设备认为波束失败恢复成功。
又例如，终端设备执行：如果波束失败恢复配置所配置的全部参考信号(例如第一部分参考信号以及第二部分参考信号)对应的波束的测量结果均小于或等于第一阈值，则终端设备选择一个波束并发起基于竞争随机接入资源的随机接入过程。在发起竞争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功。
又例如，如果第一部分参考信号对应的波束的测量结果以及第二部分参考信号对应的波束的测量结果中存在至少一个参考信号对应的波束的测量结果大于第一阈值，则终端设备选择测量结果大于第一阈值的波束关联的非竞争随机接入资源发起随机接入过程。在发起非竞争随机接入过程后，如果成功接收到第一网络设备的响应，则终端设备认为波束失败恢复成功。
以及如果波束失败恢复配置所配置的全部参考信号(例如第一部分参考信号以及第二部分参考信号)对应的波束的测量结果均小于或等于第一阈值，则终端设备选择一个波束并发起基于竞争随机接入资源的随机接入过程。在发起竞争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功。
一方面，本申请实施例允许第一网络设备配置的波束失败恢复配置中涉及的参考信号不一定都是终端设备可实际测量的参考信号，可以节约第一网络设备发送实际测量参考信号的资源，换句话说，相比基于非AI的波束失败恢复机制，第一网络设备可以为基于AI的波束失败恢复机制配置更少的需要终端设备实际测量的参考信号资源，但由于波束失败恢复机制引入了基于AI的波束预测功能，基于AI的波束失败恢复机制可以在测量较少参考信号的条件下实现不错的波束失败恢复功能，体现了AI技术的优势。
另一方面，在本申请实施例中，若波束失败恢复配置涉及第二部分参考信号(即不需要终端设备实际测量的参考信号)，则终端设备可以通过推理获得第二部分参考信号对应的测量结果，其中，确定第 二部分参考信号对应的测量结果的过程相对简单。
如上文所述，第二部分参考信号可以是基于第一参数指示的，此时，第二部分参考信号所关联的波束关联的非竞争随机接入资源均能用于波束失败恢复。在另一些实现方式中，第二部分参考信号所关联的波束关联的非竞争随机接入资源是否能用于波束失败恢复，可以基于第一条件确定。下文先介绍本申请实施例的第一条件。
在一些实现方式中，第一条件包括以下一种：目标波束集指示的全部波束的测量结果均大于第二阈值；目标波束集指示的全部波束中测量结果最好的前K个波束的测量结果均大于第二阈值；与测量结果预测相关的AI功能仍然处于激活状态。
在一些实现方式中，第一条件包括与测量结果预测相关的AI功能仍然处于激活状态(或者说，与测量结果预测相关的AI功能处于激活状态)，其中，与测量结果相关的AI功能可以理解为基于AI的波束管理功能和/或基于AI的波束失败恢复功能。
在一些实现方式中，以测量结果为RSRP测量结果为例，目标波束集指示的全部波束的测量结果均大于第二阈值，可以包括目标波束集指示的全部波束的RSRP测量结果均大于第二阈值。其中，第二阈值可以是通过波束失败恢复配置所配置的或者通过协议定义过程配置的。
在本申请实施例中，对第二阈值不作限定。在一些实现方式中，第二阈值可以与第一阈值为相同的阈值，以简化波束失败恢复配置。在另一些实现中，第二阈值可以与第一阈值为不同的阈值(即相互独立的配置)，有助于提高第二阈值设置的灵活性。
在一些实现方式中，目标波束集指示的全部波束中测量结果最好的前K个波束的测量结果均大于第二阈值，其中，K为大于或等于1的正整数。也即是说，目标波束集中波束集合1中波束的测量结果均大于第二阈值，波束集合1中波束的测量结果均大于或等于目标波束集中除波束集合1中波束之外的其他波束对应的测量结果。
以测量结果为RSRP测量结果为例，目标波束集指示的全部波束中测量结果最好的前K个波束的RSRP测量结果均大于第二阈值。
在本申请实施例中，对第二阈值不作限定。在一些实现方式中，第二阈值可以与第一阈值为相同的阈值，或者说，第一阈值以及第二阈值通过波束失败恢复配置中相同的参数配置，以简化波束失败恢复配置。在另一些实现中，第二阈值可以与第一阈值为不同的阈值，或者说，第一阈值以及第二阈值通过波束失败恢复配置中不同的参数配置，有助于提高第二阈值设置的灵活性。
在本申请实施例中，对目标波束集不作限定。在一些实现方式中，上述目标波束集包括以下一种：需要终端设备实际测量的参考信号中全部参考信号所关联的波束；第一部分参考信号中全部参考信号所关联的波束；需要终端设备实际测量的参考信号中部分参考信号所关联的波束；第一波束集合。其中，关于需要终端设备实际测量的参考信号，第一部分参考信号以及第二部分参考信号可以参见上文的介绍。
在一些实现方式中，目标波束集包括需要终端设备实际测量的参考信号中部分参考信号所关联的波束，其中，部分参考信号所关联的波束的测量结果能用于推理获得第二部分参考信号所关联的波束的测量结果。
在一些实现方式中，第一波束集合为第一网络设备通过波束失败恢复配置为终端设备配置的或者通过层3或层1测量配置为终端设备配置的。在本申请实施例中，如果第一波束集合为第一网络设备通过波束失败恢复配置为终端设备配置的，则承载第一波束集合的参数与承载第一部分参考信号的参数以及承载第二部分参考信号的参数都不同，或者说，指示第一波束集合的参数、指示第一部分参考信号的参数以及指示第二部分参考信号的参数均为不同的参数。
在一些场景中，目标波束集可以是预先约定的。例如，可以通过协议预定。因此，目标波束集又称为“约定的波束集合”。
为了便于理解，下文结合示例7～示例10介绍本申请实施例的目标波束集。假设第一参考信号集合中第一部分参考信号包含通过SSB波束标识1指示的参考信号以及通过SSB波束标识3指示的参考信号。第一网络设备通过层3(或层1)测量配置或者通过波束失败恢复配置所配置的需要终端设备实际测量的参考信号对应的波束包括：通过SSB波束标识1指示的波束、通过SSB波束标识3指示的波束、通过SSB波束标识5指示的波束以及通过SSB波束标识7指示的波束。
另外，第一参考信号集合中第二部分参考信号包含通过SSB波束标识2指示的参考信号以及通过SSB波束标识4指示的参考信号。第一网络设备通过层3(或层1)测量配置或者通过波束失败恢复配置所配置的不需要终端设备实际测量的参考信号对应的波束包括通过SSB波束标识2指示的波束、通过SSB波束标识4指示的波束、通过SSB波束标识6指示的波束以及通过SSB波束标识8指示的波束。
需要说明的是，为了后续描述，下文将“SSB波束标识n指示的波束”简称为SSB波束n，其中，n的取值为正整数。
示例7：若目标波束集包括需要终端设备实际测量的参考信号中全部参考信号所关联的波束，则目标波束集包括SSB波束1、SSB波束3、SSB波束5以及SSB波束7。
示例8：若目标波束集包括第一部分参考信号对应的全部波束，则目标波束集包括SSB波束1以及SSB波束3。
示例9：若目标波束集包括需要终端设备实际测量的参考信号中部分参考信号所关联的波束，则目标波束集包括SSB波束1、SSB波束3以及SSB波束5。这是由于第二部分参考信号对应的波束包括SSB波束2以及SSB波束4，如果想要推理获得第二部分参考信号对应的波束的测量结果，则需要将SSB波束1的测量结果、SSB波束3的测量结果以及SSB波束5的测量结果作为AI模型输入。
示例10：若目标波束集包括第一波束集合，例如，第一波束集合包含SSB波束1以及SSB波束7。
一方面，本申请实施例的方案允许网络设备配置的波束失败恢复配置中涉及的参考信号不一定都是终端设备可实际测量的参考信号可以节约网络设备发送实际测量参考信号的资源，换句话说，相比基于非AI的波束失败恢复机制，网络设备可以为基于AI的波束失败恢复机制配置更少的需要终端设备实际测量的参考信号资源，但由于波束失败恢复机制引入了基于AI的波束预测功能，基于AI的波束失败恢复机制可以在测量较少参考信号的条件下实现不错的波束失败恢复功能，体现了AI技术的优势。
另一方面，能否通过AI功能推理过程获得第二部分参考信号对应的测量结果不仅取决于波束失败恢复配置是否涉及第二部分参考信号，还取决于第一条件是否满足，这样做的好处在于避免在精度较差的条件下执行AI推理过程，有助于提高基于AI的波束失败恢复功能的性能。否则，在第一条件不满足时仍然执行AI推理过程，得到精度不高的第二部分参考信号对应的测量结果反而会影响波束失败恢复功能整体的性能，所以，通过判断第一条件来决定是否执行AI推理过程有利于保障基于AI的波束失败恢复功能的整体性能。
上文介绍了本申请实施例中的第一条件，下文结合本申请实施例的方案分别介绍满足第一条件或不满足第一条件时的第一操作。
基于上文的介绍可知，在满足第一条件的情况下，第二部分参考信号所关联的波束关联的非竞争随机接入资源均能用于波束失败恢复(准确来说，在满足第一条件的情况下，第二部分参考信号所关联的波束关联的非竞争随机接入资源可以当做波束失败恢复过程的候选资源，实际能不能使用需要取决于第二部分参考信号所关联的波束的测量结果是否大于前述第一阈值)，此时，终端设备执行的第一操作与未引入第一条件时终端设备执行的第一操作类似，具体可以参见前文的介绍，例如，结合示例1～示例6所介绍的第一操作。
在一些实现方式中，在满足第一条件的情况下，若第二波束的测量结果大于第一阈值，则第一操作包括基于第二波束关联的第二非竞争随机接入资源发起随机接入过程，其中，第二波束为第一部分参考信号所关联的波束中的一个波束或者第二波束为第二部分参考信号所关联的波束中的一个波束；和/或
若第三波束的测量结果小于或等于第一阈值，则第一操作包括基于竞争随机接入资源发起随机接入过程，其中，第三波束为第一部分参考信号所关联的波束中的任意一个波束或者第三波束为第二部分参考信号所关联的波束中的任意一个波束。
也即是说，若终端设备获取了波束失败恢复配置所配置的全部参考信号对应的波束的测量结果(即第一部分参考信号对应的波束的测量结果以及第二部分参考信号对应的波束的测量结果)，则终端设备可以继续执行以下中的一种或多种操作。
例如，终端设备执行：以测量结果为RSRP测量结果为例，如果第一部分参考信号对应的波束的RSRP测量结果以及第二部分参考信号对应的波束的RSRP测量结果中存在至少一个参考信号对应的波束的RSRP测量结果大于波束失败恢复配置中包含的第一阈值，则终端设备选择上述波束的RSRP测量结果大于第一阈值的波束关联的非竞争随机接入资源发起随机接入过程。在发起非竞争随机接入过程后，如果成功接收到第一网络设备的响应，则终端设备认为波束失败恢复成功。
相反地，如果第一网络设备配置的波束失败恢复配置所配置的全部参考信号对应的波束的RSRP测量结果均小于或等于波束失败恢复配置中包含的第一阈值，则终端设备可以选择一个波束并发起基于竞争随机接入资源的随机接入过程。在发起竞争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功。其中，本申请实施例对终端设备选择波束的方式不作限定，可以取决于终端设备的实现。
又例如，终端设备执行：以测量结果为RSRP测量结果为例，如果第一部分参考信号对应的波束的RSRP测量结果以及第二部分参考信号对应的波束的RSRP测量结果中存在至少一个参考信号对应的波束的RSRP测量结果大于波束失败恢复配置中包含的第一阈值，则终端设备选择上述波束的RSRP测量结果大于第一阈值的波束关联的非竞争随机接入资源发起随机接入过程。在发起非竞争随机接入过程后， 如果成功接收到第一网络设备的响应，则终端设备认为波束失败恢复成功。
又例如，终端设备执行：如果第一网络设备配置的波束失败恢复配置所配置的全部参考信号对应的波束的RSRP测量结果均小于或等于波束失败恢复配置中包含的第一阈值，则终端设备可以选择一个波束并发起基于竞争随机接入资源的随机接入过程。在发起竞争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功。其中，本申请实施例对终端设备选择波束的方式不作限定，可以取决于终端设备的实现。
在另一些实现方式中，若不满足第一条件，则不执行上文介绍的第一操作(例如，结合示例1～示例6所介绍的第一操作)。或者说，第一操作在不满足第一条件的情况下不执行或者停止执行(例如，终端设备也可能在波束失败事件发生前激活AI预测功能，便于终端设备在发生波束失败事件后且第一条件满足时快速推理获得第二部分参考信号对应的波束的测量结果)。其中，不满足第一条件用于指示第二部分参考信号所关联的波束关联的非竞争随机接入资源不能用于波束失败恢复。也就是说，此时，只有第一部分参考信号所关联的波束关联的非竞争随机接入资源会用于波束失败恢复过程。
在一些实现方式中，在不满足第一条件的情况下，若第一部分参考信号所关联的波束中第四波束的测量结果大于第一阈值，则第一操作包括基于第四波束关联的第三非竞争随机接入资源发起随机接入过程；和/或，若第一部分参考信号所关联的波束的测量结果小于或等于第一阈值，则第一操作包括基于第一部分参考信号所关联的波束中的某一波束关联的竞争随机接入资源发起随机接入过程。
以测量结果为RSRP测量结果为例，如果第一条件不满足，终端设备通过测量过程获得全部需要终端设备实际测量的参考信号对应的波束的RSRP测量结果，其中，需要终端设备实际测量的参考信号包括第一部分参考信号对应的波束的RSRP测量结果。
通过上述方式，终端设备在获取了第一部分参考信号对应的波束的RSRP测量结果之后，可以继续执行以下一种或多种操作。
例如，终端设备执行：如果第一部分参考信号对应的波束的RSRP测量结果中存在至少一个参考信号对应的波束的RSRP测量结果大于第一阈值，则终端设备选择RSRP测量结果大于第一阈值的波束关联的非竞争随机接入资源发起随机接入过程。在发起非竞争随机接入过程后，如果成功接收到第一网络设备的响应，则终端设备认为波束失败恢复成功。
以及如果第一部分参考信号对应的波束的RSRP测量结果均小于或等于第一阈值，则终端设备选择一个波束并发起基于竞争随机接入资源的随机接入过程。在发起竞争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功。其中终端设备选择波束的方式可以取决于终端设备实现。
又例如，终端设备执行：如果第一部分参考信号对应的波束的RSRP测量结果中存在至少一个参考信号对应的波束的RSRP测量结果大于第一阈值，则终端设备选择RSRP测量结果大于第一阈值的波束关联的非竞争随机接入资源发起随机接入过程。在发起非竞争随机接入过程后，如果成功接收到第一网络设备的响应，则终端设备认为波束失败恢复成功。
又例如，终端设备执行：如果第一部分参考信号对应的波束的RSRP测量结果均小于或等于第一阈值，则终端设备选择一个波束并发起基于竞争随机接入资源的随机接入过程。在发起竞争随机接入过程后，如果成功完成竞争解决，则终端设备认为波束失败恢复成功。其中终端设备选择波束的方式可以取决于终端设备实现。
在一些实现方式中，上述方法还包括：若发生第一事件，终端设备执行第二操作，第二操作包括：终端设备停止基于AI的波束管理功能；和/或波束失败恢复成功后，终端设备回退到基于非AI的波束管理功能。
在一些实现方式中，若终端设备检测到波束失败事件发生后，可能说明基于AI的波束管理功能所述选择的波束性能较差，此时，终端设备可以停止基于AI的波束管理功能。
在一些实现方式中，若终端设备检测到波束失败事件发生后，可能说明基于AI的波束管理功能所述选择的波束性能较差，此时，终端设备可以回退到基于非AI的波束管理功能进行波束测量和反馈。
在一些实现方式中，若终端设备检测到波束失败事件发生后，可能说明基于AI的波束管理功能所述选择的波束性能较差，此时，终端设备可以停止基于AI的波束管理功能，并执行波束失败恢复操作。在波束失败恢复操作成功后，终端设备可以回退到基于非AI的波束管理功能进行波束测量和反馈。
在一些实现方式中，在第一波束失败事件发生之前发生了第二波束失败事件，上述方法还包括：若发生第一波束失败事件，且第一波束失败事件发生时刻与第二波束失败事件发生时刻之间的时间间隔小于第一时间阈值，终端设备执行第三操作，其中，第三操作包括以下一种或多种：终端设备停止基于AI的波束管理功能；波束失败恢复执行成功后，终端设备向第一网络设备发送第一信息；波束失败恢复执行成功后，终端设备回退到基于非AI的波束管理功能。第一时间阈值通过以下一种或多种方式配置给终端设备：专用信令方式；系统广播消息方式；协议预定义方式。
在一些实现方式中，第二波束失败事件为第一波束失败事件的上一次波束失败事件。当然，在本申请实施例中，第二波束失败事件与第一波束失败事件之间可以间隔一次或多次波束失败事件。
以第三操作包括终端设备停止基于AI的波束管理功能为例，若发生第二波束失败事件之后又发生第一波束失败事件，可能说明基于AI的波束管理功能所选择的波束的性能较差，此时，终端设备停止基于AI的波束管理功能。
以第三操作包括终端设备向第一网络设备发送第一信息为例，终端设备向第一网络设备发送第一信息，可以替换为终端设备向服务小区发送第一信息。
在本申请实施例中，若发生第二波束失败事件之后又发生第一波束失败事件，可能说明基于AI的波束管理功能所选择的波束的性能较差，此时，终端设备可以通过第一信息向第一网络设备指示终端设备检测到第一波束失败事件。
以第三操作包括波束失败恢复执行成功后，终端设备回退到基于非AI的波束管理功能为例，若发生第二波束失败事件之后又发生第一波束失败事件，可能说明基于AI的波束管理功能所选择的波束的性能较差，此时，在波束失败恢复执行成功后，终端设备回退到基于非AI的波束管理功能。
在本申请实施例中，上文介绍的第三操作可以相互独立使用，或者上文介绍的第三操作可以相互结合使用。
例如，发生第一波束失败事件时，终端设备可以停止基于AI的波束管理功能，并在波束失败恢复操作成功后，向服务小区发送第一信息，以指示终端设备检测到第一波束失败事件。
又例如，发生第一波束失败事件时，终端设备可以停止基于AI的波束管理功能。并在波束失败恢复操作成功后，回退到基于非AI的波束管理功能进行波束测量和反馈。
又例如，发生第一波束失败事件时，终端设备可以触发波束失败恢复操作，并在波束失败恢复操作成功后，终端设备向服务小区发送第一信息，以指示终端设备检测到第一波束失败事件。同时，在波束失败恢复操作成功后，终端设备可以回退到基于非AI的波束管理功能进行波束测量和反馈。
又例如，终端设备检测到第一波束失败事件，并判断波束失败发生时，终端设备停止基于AI的波束管理功能。之后，若波束失败恢复操作成功，终端设备向服务小区发送第一信息，以指示终端设备检测到第一波束失败事件。同时，波束失败恢复操作成功后，终端设备回退到基于非AI的波束管理功能进行波束测量和反馈。
在一些实现方式中，若发生第一波束失败事件，且波束失败恢复执行失败，可以执行操作1～操作3中的一种或多种。例如，可以执行操作1。又例如，可以执行操作2。又例如，可以执行操作3。又例如，可以执行操作1以及操作2。又例如，可以执行操作1以及操作3。又例如，可以执行操作2以及操作3。又例如，可以执行操作1，操作2以及操作3。
操作1：触发连接重建立过程，终端设备可以向第二网络设备发送第一MAC CE(又称“第一MAC CE信息”)，第一MAC CE用于指示终端设备波束失败恢复执行失败。
也即是说，若终端设备检测到波束失败事件发生且波束失败恢复操作失败，则终端设备执行如下行为：触发连接重建立过程，向连接重建立过程选择的小区发送第一MAC CE，第一MAC CE用于指示终端设备发生了波束失败恢复操作失败。
在一些实现方式中，第一MAC CE信息可以包括第四信息和/或第一小区标识信息。其中，第四信息用于指示终端设备发生了波束失败恢复操作失败。第一小区标识信息用于指示发生波束失败恢复操作失败事件的小区。例如：第一小区标识信息通过CGI或者(PCI+频点信息)或服务小区标识(serving cell index)指示。
在一些实现方式中，第一MAC CE信息与连接重建立请求消息一起发送。如此，终端设备可以尽早通知连接重建立过程选择的小区触发连接重建立的具体原因。传统的连接重建立请求消息包含的连接重建立触发原因(ReestablishmentCause)非常的少(见下文代码中所示的重配失败(reconfigurationFailure)，切换失败(handoverFailure)以及其他失败(otherFailure)这三个原因)，受限于连接重建立请求消息承载的比特数。而直接扩展重建立请求消息来进一步指示终端设备触发连接重建立的具体原因信息所对传统通信过程改动较大。因此，本申请实施例提出通过MAC层定义的第一MAC CE来承载连接重建立请求消息所无法承载的终端设备触发连接重建立的具体原因信息，从而让终端设备连接重建立过程选择的小区在收到连接重建立请求消息的同时收到第一MAC CE，以辅助第二网络设备判断是回复连接重建立消息还是连接建立消息。
ReestablishmentCause::＝ENUMERATED{reconfigurationFailure,handoverFailure,otherFailure,spare1}
当然，在本申请实施例中，第一MAC CE与连接重建立请求消息分开发送，以提高传输第一MAC CE的灵活性。
在一些实现方式中，第二网络设备为通过连接重建立过程选择的网络设备。第二网络设备可能与第 一网络设备为不同的网络设备，当然，在本申请实施例中，第一网络设备可以与第二网络设备为相同的网络设备。
操作2：触发连接重建立过程，终端设备向第二网络设备发送连接重建立完成消息，且连接重建立完成消息包括第二信息，第二信息用于指示终端设备波束失败恢复执行失败。其中，第二网络设备为通过连接重建立过程选择的网络设备。
也即是说，终端设备检测到波束失败事件发生且波束失败恢复操作失败，终端设备执行如下行为：触发连接重建立过程，向连接重建立过程选择的小区(即第二网络设备)发送连接重建立完成消息且连接重建立完成消息包括第二信息，以指示终端设备发生了波束失败恢复操作失败。
该方式下，终端设备向连接重建立过程选择的小区发送连接重建立请求消息，接着网络设备回复终端设备连接重建立消息。之后，终端设备可以向连接重建立过程选择的小区发送连接重建立完成消息其中，连接重建立完成消息包括第二信息，以指示终端设备发生了波束失败恢复操作失败。
在一些实现方式中，第二信息还包括第二小区标识信息，其中，第二小区标识信息用于指示发生波束失败恢复操作失败事件的小区。例如，第二小区标识信息可以通过CGI或者(PCI+频点信息)或服务小区标识(serving cell index)指示。
在本申请实施例中，通过在连接重建立完成消息中携带第二信息，可以让第二网络设备知道终端设备触发连接重建立的具体原因，即终端设备发生了波束失败恢复操作失败。这样一来，第二网络设备可以考虑去激活基于AI的波束管理功能(也就是回退到使用基于非AI的波束管理功能)，避免基于AI的波束管理功能给系统带来更长时间的性能下降。
在一些实现方式中，第二网络设备为通过连接重建立过程选择的网络设备。第二网络设备可能与第一网络设备为不同的网络设备，当然，在本申请实施例中，第一网络设备可以与第二网络设备为相同的网络设备。
操作3：触发连接重建立过程，终端设备向第二网络设备发送连接建立完成消息，且连接建立完成消息包括第三信息，第三信息用于指示终端设备波束失败恢复执行失败。其中，第二网络设备为通过连接重建立过程选择的网络设备。
也即是说，终端设备检测到波束失败事件发生且波束失败恢复操作失败，终端设备执行如下行为：触发连接重建立过程，向连接重建立过程选择的小区(即第二网络设备)发送连接重建立请求消息，相应地，连接重建立过程选择的小区向终端设备回复的是连接建立消息(对应重建立回退场景)，则终端设备向连接重建立过程选择的小区发送连接建立完成消息，其中，连接建立完成消息包括第三信息，以指示终端设备发生了波束失败恢复操作失败。
在一些实现方式中，第三信息还包括第三小区标识信息，第三小区标识信息用于指示发生波束失败恢复操作失败事件的小区。例如，第三小区标识信息通过CGI或者(PCI+频点信息)或服务小区标识(serving cell index)指示。
在本申请实施例中，通过在连接重建立完成消息中携带第三信息，可以让第二网络设备知道终端设备触发连接重建立的具体原因，即终端设备发生了波束失败恢复操作失败。这样一来，第二网络设备可以考虑去激活基于AI的波束管理功能(也就是回退到使用基于非AI的波束管理功能)，避免基于AI的波束管理功能给系统带来更长时间的性能下降。
在一些实现方式中，第二网络设备为通过连接重建立过程选择的网络设备。第二网络设备可能与第一网络设备为不同的网络设备，当然，在本申请实施例中，第一网络设备可以与第二网络设备为相同的网络设备。

需要说明的是，上述操作2与操作3并不是互斥的方案，而是一种方案的两个不同分支，操作2针对的是终端设备向网络设备发送连接重建立请求消息，相应地，第二网络设备回复连接重建立消息的分 支。而操作3针对的是终端设备向第二网络设备发送连接重建立请求消息，相应地，第二网络设备回复连接建立消息的分支。
