技术领域
本申请属于通感一体化技术领域，具体涉及一种波束恢复方法、装置及终端。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)的第15版(Release 15，R15)协议规范中新空口(New Radio，NR)波束失败检测和恢复流程如下：
1、每个运行实例(time instance)，物理层测量高层信令发送的参数failureDetectionResources指示的至少一个参考信号(Reference Signal，RS)，推算出对应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的接收块误码率(block error rate，BLER)性能；
RS可以是同步信号和物理广播信道(Synchronization Signal and PBCH block，SSB)信号或者信道状态信息参考信号(Channel-State-Information Reference Signal，CSI-RS)或者二者的混合。
2、如果BLER性能高于目标BLER门限如10％，则物理层向高层(媒体接入控制(Medium Access Control，MAC)层)上报波束失败实例(beam failure instance)；
所有RS都满足条件才上报beam failure instance。
3、如果物理层上报的beam failure instance达到预设次数，声明beam failure；
4、用户设备(User Equipment，UE)搜索候选RS，如果找到了满足门限的RS，UE上报满足门限的CRI/L1-RSRP或SSBRI/L1-RSRP给MAC层；
5、MAC层选择满足门限的RS以及对应的物理随机接入信道(Physical Random Access Channel，PRACH)资源；
6、UE向基站发送(或重新发送)波束失败恢复请求(beam failure recovery request)；
7、如果基站收到了beam failure recovery request，则在对应的资源上通过PDCCH发送响应(response)；
8、UE接收到response，则链路恢复(Link Recovery)成功；若beam failure recovery request达到最大次数仍未收到response，则Link Recovery失败。
但是目前的波束恢复流程不适用于通感一体化的场景。
