技术领域
本公开涉及通信技术领域，特别涉及一种接收模式调整方法、无线链路质量确定方法及终端。
背景技术
在第五代(5Generation，5G)系统中，要求用户设备工作在一些特定的频段时如2.6GHz、3.5GHz和4.8GHz时必须支持接收天线数为4。但某些场景下接收天线数为2基本可以满足需求，例如，下行信息为小数据包的情况，此时采用2天线接收方式就能够满足需求如业务服务质量(Quality of Service，QoS)需求；如果用户设备仍采用4天线接收下行信息，则将导致用户设备耗费不必要的电量，不利于用户设备节省电能。
而在无线链路监听(Radio link monitoring，RLM)和链路恢复(Link Recovery)过程中，UE的激活天线数或者激活天线面板(panel)数保持不变，例如，无法增加接收天线数或者panel数，从而无法改善RLM和Link Recovery的性能。
发明内容

A12、如果所述无线链路质量满足目标门限(例如假想PDCCH的2％误块率(Block Error Ratio，BLER)对应的无线链路质量)，则物理层向高层(RRC层)上报无线链路同步(In-Sync，IS)；
只要有一个RS满足条件就上报IS。

A16、否则，宣告无线链路失败(Radio Link Failure)；
若出现无线链路失败，则需要进行RRC重建。
A2、链路恢复(Link Recovery)过程

需要说明的是，所有RS都满足条件才上报OOS。
P14、如果连续上报OOS数量超过一个阈值N310，则启动T310计数器；
P15、如果在T310计数器运行期间，连续上报的IS数量达到一定的阈值N311，则停止T310计数器(此时仍保持RRC连接)；
P16、否则，宣告无线链路失败(Radio Link Failure)；
在宣告无线链路失败后，则进行RRC重建。
例如，在此种情况下，链路恢复的具体实现流程为：
P21、每个time instance，终端的物理层通过第二模式测量网络设备的高层信令发送的参数失败检测资源(failureDetectionResources)指示的至少一个RS，以评估无线链路质量；
需要说明的是，该RS可以是SSB或者CSI-RS，或者二者的混合。
P22、如果所述无线链路质量无法满足目标门限(例如假想PDCCH的5％BLER对应的无线链路质量)，则物理层向高层(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。
P23、如果物理层上报的beam failure instance达到预设次数，声明波束失 败(beam failure)；
P24、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CSI-RS资源索引(CSI-RS Resource Index，CRI)/层1参考信号接收功率(Layer1Reference Signal Received Power，L1-RSRP)或同步信号块资源索引(SSBRI)/L1-RSRP给MAC层；
P25、高层选择满足门限的RS以及对应的物理随机接入信道(Physical Random Access Channel，PRACH)资源；
P26、UE向基站发送(或重新发送)波束失败恢复请求(beam failure recovery request)；
P27、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)；
P28、UE接收到response，则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。
需要说明的是，此种实现方式直接通过预设接收模式进行RLM过程和/或链路恢复过程，可以改善RLM或链路恢复的性能，提高通信可靠性。
