图1示出了本申请一个示例性实施例提供的WLAN系统的框图。该WLAN系统包括：接入点(AccessPoint，AP)和站点(Station，STA)。
在一些场景中，AP可以或称AP STA，即在某种意义上来说，AP也是一种STA。在一些场景中，STA或称非AP STA(non-AP STA)。
在一些实施例中，STA可以包括AP STA和non-AP STA。
通信系统中的通信可以是AP与non-AP STA之间通信，也可以是non-AP STA与non-AP STA之前通信，或者STA和peer STA之间通信，其中，peer STA可以指与STA对端通信的设备，例如，peer STA可能为AP，也可能为non-AP STA。
AP相当于一个连接有线网和无线网的桥梁，主要作用是将各个无线网络客户端连接到一起，然后将无线网络接入以太网。AP设备可以是带有无线保真(Wireless-Fidelity，WiFi)芯片的终端设备(如手机)或者网络设备(如路由器)。
应理解，STA在通信系统中的角色不是绝对的，例如，在一些场景中，手机连接路由的时候，手机是non-AP STA,手机作为其他手机的热点的情况下，手机充当了AP的角色。
AP和non-AP STA可以是应用于车联网中的设备，物联网(Internet ofThings，IoT)中的物联网节点、传感器等，智慧家居中的智能摄像头，智能遥控器，智能水表电表等，以及智慧城市中的传感器等。

WLAN技术可支持频段可以包括但不限于：低频段(2.4GHz、5GHz、6GHz)、高频段(60GHz)。
站点和接入点之间存在一个或多个链路。
在一些实施例中，站点和接入点支持多频段通信，例如，同时在2.4GHz，5GHz，6GHz以及60GHz频段上进行通信，或者同时在同一频段(或不同频段)的不同信道上通信，提高设备之间的通信吞吐量和/或可靠性。这种设备通常称为多频段设备，或称为多链路设备(Multi-Link Device，MLD)，有时也称为多链路实体或多频段实体。多链路设备可以是接入点设备，也可以是站点设备。如果多链路设备是接入点设备，则多链路设备中包含一个或多个AP；如果多链路设备是站点设备，则多链路设备中包含一个或多个non-AP STA。
包括一个或多个AP的多链路设备或称AP，包括一个或多个non-AP STA的多链路设备或称Non-AP，在申请实施例中，Non-AP可以称为STA。
在本申请实施例中，AP可以包括多个AP，Non-AP包括多个STA，AP中的AP和Non-AP中的STA之间可以形成多条链路，AP中的AP和Non-AP中的对应STA之间可以通过对应的链路进行数据通信。
AP是一种部署在无线局域网中用以为STA提供无线通信功能的设备。站点0可以包括：用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、用户代理或用户装置。可选地，站点10还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digita1Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，本申请实施例对此并不限定。

又由于感知和通信在整个WLAN系统中可能同时存在，需要考虑它们互相影响可能导致的用户体验下降，例如视频数据负载较高时如果进行感知测量则可能导致视频卡顿，所以也需要进行相应处理。如图18所示：

图19示出了本申请一个示例性实施例提供的异常处理方法的流程图。本实施例以该方法由站点管理实体和上层应用执行来举例说明。该方法包括：
步骤802：感知发起设备接收第一感知响应设备发送的状态变化信息；
第一感知响应设备在自身操作模式发生变化时，向站点管理设备发送状态变化信息。也即，状态变化信息是第一感知响应设备在自身操作模式发生变化时发送的。

综上所述，本实施例提供的方法，通过在站点管理实体监测到感知响应设备的状态变化信息满足第一上报条件的情况下，向上层应用上报异常状态，使得上层应用能够感知和处理异常状态，及时暂停/结束/更新感知测量设置，从而实现对异常状态的处理。
图20示出了本申请一个示例性实施例提供的异常处理方法的流程图。本实施例以该方法由站点管理实体和上层应用执行来举例说明。该方法包括：
步骤902：站点管理实体在感知测量的状态参数满足第二上报条件的情况下，生成异常状态；
示意性的，第二上报条件包括如下四种条件中的任意一种：
·参与测量的感知响应设备的数量小于所述上层应用指定的最小数量；
·参与测量的感知响应设备的数量小于所述上层应用指定的最小数量，且存在至少一个第二感知响应设备，第二感知响应设备是用于替换第一感知响应设备的设备；
·参与测量的感知响应设备的数量小于所述上层应用指定的最小数量，且不存在至少一个所述第二感知响应设备；
·BSS负载达到阈值。
在站点损坏，或站点电量不足，或站点因用户操作而主动跟AP解除关联，或站点离开BSS覆盖范围而解除关联的情况下，感知响应设备变少，感知发起设备中的站点管理实体检测出感知响应设备变少。
其中，BSS负载采用如下指标中的至少一种指示：

·测距占用率；
测距占用的时间在测算总时间中的比率。

相应的，上述阈值通常是一个阈值或多个阈值的组合。比如，上述阈值可能都包括以下阈值中的至少一个：信道利用率阈值、可用的准入时间阈值、感知占用率阈值、测距占用率阈值、感知和测距占用率阈值。
步骤904：站点管理实体通过第六接口，向上层应用上报异常状态。
示意性的，异常状态包括如下至少一种：

结束第一感知响应设备的感知测量设置；
与第二感知响应设备建立感知测量设置，第二感知响应设备是用于替换第一感知响应设备的设备。
综上所述，本实施例提供的方法，通过在站点管理实体监测到BSS负载满足第二上报条件的情况下，向上层应用上报异常状态，使得上层应用能够感知和处理异常状态，及时暂停/结束/更新感知测量设置，从而实现对异常状态的处理。
示例一：感知响应设备数目变少；
在一些实施例中，上层应用(例如步态识别应用)需要多个感知响应设备参与感知测量才能得到精度足够的测量结果，而在运行中某个或某些第一感知响应设备可能出现异常(例如：站点损坏，或站点电量不足，或站点因用户操作而主动跟AP解除关联，或站点离开BSS覆盖范围而解除关联)而不能继续参与测量，导致参与测量的总站点数目变少，以致无法满足上层应用的精度要求。
因此，上层应用通过前述用于建立测量设置的第一接口给感知发起设备的SME指示参与感知测量的设备的最小数目。在参与测量的总站点数目变少时，感知发起设备的SME需要通过前述上报执行状态的第六接口给上层应用指示测量设置标识符和异常状态的错误代码(具体为发生站点数目减少)：
如果上层应用没有指定参与测量的具体站点，且如果有一个或多个可替换的站点，感知发起设备的SME可以不用通知上层应用，而自动使用可替换的站点。也即，SME通过建立测量设置的接口指示感知发起设备与可替换的站点建立相应的感知测量设置。其中，被替换的站点即为第一感知响应设备；可替换的站点即为第二感知响应设备。
如果上层应用指定了参与测量的具体站点，且如果有一个或多个可替换的站点，感知发起设备的SME还可以给上层应用指示有一个或多个可替换的站点，上层应用可以自动确认使用可替换的站点；也可以提示用户，让用户确认是否使用可替换的站点。如果用户确认使用，则使用所述可替换的站点；如果用户确认不使用，则通过结束测量设置的第二接口指示感知发起设备与该感知测量设置所涉及的所有感知响应设 备结束该感知测量设置。
如果上层应用没有指定参与测量的具体站点，或者，如果上层应用指定参与测量的具体站点且没有可替换的站点，上层应用可以自动确认继续进行测量，或者自动结束该感知测量设置，并通过上报执行状态的第六接口给上层应用指示测量设置标识符和错误代码(具体为因站点数目减少导致自动结束测量)，也可以提示用户，让用户确认是否忽略该异常而继续进行测量。如果用户确认继续，则继续测量；如果用户确认不继续，则通过结束测量设置的第二接口指示感知发起设备与该感知测量设置所涉及的所有感知响应设备结束该感知测量设置。
示例二：感知响应设备操作模式变化；
当第一感知响应设备出现电量不足但想延长工作时，会进行操作模式(OM，Operating Mode)变化(降低带宽和/或减少能支持的发送空域流数目和/或减少能支持的接收空域流数目)来达到延长工作时长的效果。操作模式变化后可能会对感知过程产生影响，例如带宽越小感知结果的量化误差越大，空域流数目越小感知结果的CSI矩阵维度降低，导致感知的准确性降低。
感知响应设备(例如non-AP STA)在其自身操作模式发生变化时，会给感知发起设备(例如AP)发送操作模式通知(OMN，Operating Mode Notification)或者操作模式指示(OMI，Operating Mode Indication),感知发起设备收到后通过上报执行状态的接口给上层应用指示测量设置标识符、错误代码(具体为站点操作模式变化)和相关信息(包括相应感知响应设备的标识符，和/或变化后能支持的最大带宽，和/或变化后能支持的最大发送空域流数目，和/或变化后能支持的最大接收空域流数目)。其中，OMN可以是OMN帧，也可以是携带OMN元素的其他帧。其中，OMI是携带有操作模式控制子字段(OM Control subfield)和/或EHT操作模式控制子字段(EHTOM Control subfield)的帧。
上层应用可以自动确认继续使用该站点。示意性的，若变化后能支持的最大带宽和能支持的最大发送空域流数目和能支持的最大接收空域流数目仍能满足上层应用指示的相关精度需求则无需更多处理；若不能满足，则通过结束测量设置的接口指示感知发起设备与该感知响应设备结束相应的感知测量设置，然后通过建立测量设置的接口指示感知发起设备与该感知响应设备建立更新的测量设置，更新的测量设置可以包括更新的感知带宽，和/或更新的感知发送空时流数目，和/或更新的感知接收空时流数目，和/或更新的感知角色。
上层应用也可以自动结束该测量设置，比如通过结束测量设置的接口指示感知发起设备与该感知测量设置所涉及的所有感知响应设备结束该感知测量设置)，并通过上报执行状态的接口给上层应用指示测量设置标识符和错误代码，该错误的代码为因站点操作模式变化导致自动结束测量。
上层应用也可以提示用户。让用户确认是否继续该测量；如果用户确认是，则更新测量设置如前述；如果用户确认否，则结束测量设置如前述。
示例三：BSS负载太高；
在一个示例中，AP通过测算信道利用率、可用的准入时间等指标能够判断BSS负载情况，在写字楼、商场、体育场、展览馆等区域可能容易出现BSS负载比较高的情况。为了优先保证通信的用户体验，当BSS负载比较高时需要对感知测量进行相应的调整，例如暂停或结束感知测量设置，又例如降低周期性感知测量的频次。
AP还可以计算感知占用率、测距占用率、感知和测距占用率等指标来辅助决策处理负载较高时对感知的处理。也即，BSS负载还可以采用感知占用率、测距占用率、感知和测距占用率等指标来衡量。
感知发起设备的SME在判断BSS负载较高时，通过上报执行状态的接口给上层应用指示测量设置标识符、错误代码(具体为BSS过载)和/或BSS负载信息(例如信道利用率，和/或可用的准入时间，和/或感知占用率，和/或测距占用率,和/或感知和测距占用率)。
当BSS负载低于第一预设阈值时，上层应用可以自动确认继续进行感知测量；
当BSS负载高于第一预设阈值时，上层应用可以自动降低周期性感知测量的频次，更新测量设置比如，通过结束测量设置的接口指示感知发起设备与该感知测量设置所涉及的所有感知响应设备结束该感知测量设置，然后通过建立测量设置的接口指示感知发起设备与该感知响应设备建立更新的测量设置。上层应用也可以提示用户让用户确认是否降低周期性感知测量的频次。如果用户选择是，则更新测量设置如前述；如果用户选择否，则通过结束测量设置的接口指示感知发起设备与该感知测量设置所涉及的所有感知响应设备结束该感知测量设置。
当负载高于第二预设阈值时，上层应用可以自动确认暂停测量设置，比如通过暂停测量设置的接口指示感知发起设备与该感知测量设置所涉及的所有感知响应设备暂停该感知测量设置，也可以提示用户让用户确认是否暂停测量设置(暂停该感知测量设置如前述)。
若一段时间之后，BSS负载降低，即当负载低于第三预设阈值时，上层应用可以自动确认恢复测量设置。比如，上层应用通过恢复测量设置的接口指示感知发起设备与该感知测量设置所涉及的所有感知响应 设备恢复该感知测量设置，也可以提示用户让用户确认是否恢复测量设置(恢复该感知测量设置如前述)。
当负载高于第四预设阈值时，上层应用可以自动确认结束测量设置，比如上层应用通过结束测量设置的接口指示感知发起设备与该感知测量设置所涉及的所有感知响应设备结束该感知测量设置，也可以提示用户让用户确认是否结束测量设置(结束该感知测量设置如前述)。
