本公开实施例提供了一种WLAN感知方法及装置、电子设备及存储介质，用以解决STA作为感知发起端，造成频谱资源浪费以及时延增加的问题。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
如图1中所示，本公开实施例提供了一种WLAN感知方法，可选地，所述方法可应用于接入点设备AP，所述方法包括以下步骤：
步骤101，接收发起端设备发送的感知会话建立发起消息帧。
作为第一示例，参见图2至图4，首先介绍本公开实施例提供的WLAN感知方法所应用的WLAN Sensing的架构以及WLAN Sensing过程。
图2示出了一种WLAN Sensing的架构示意图；其中，感知发起端发起WLAN Sensing(例如，发起WLAN感知会话)，可能存在着多个感知响应端(Sensing Responder，或感知接收端)对其响应，如图2中的响应端1、响应端2和响应端3所示。当感知发起端发起WLAN Sensing时，多个关联或者非关联的WLAN Sensing的感知响应端可以进行响应。
参见图3，感知发起端与感知响应端之间通过通信连接通信，如通信连接S1所示；感知响应端之间通过通信连接S2通信。
其中，每个感知发起端可以是一个客户端(Client)；每个感知响应端(在本示例中，即感知响应端1至感知响应端3)可以是一个站点设备(STA)。STA可以在WLAN感知过程中承担多个角色，例如，在WLAN感知过程中，感知发起者可能是感测发射器(Sensing Transmitter)、 感知接收器(Sensing Receiver)，或两者都是，或都不是。在WLAN感测过程中，感测响应端也可能是感测发射器、感测接收器或两者都是。
作为另一种架构，如图4所示，感知发起端、感知响应端还可以均为客户端，二者可以通过连接到同一AP进行通信；图4中Client1为感知发起端，Client2为感知响应端。
在WLAN感知过程中，发起端设备(例如为STA)可以向AP发送感知会话建立发起消息帧，所述感知会话建立发起消息帧用于发起感知会话，感知会话建立发起消息帧例如为Sensing Session setuprequest；AP接收所述感知会话建立发起消息帧，并根据感知会话建立发起消息帧，代理发起端设备进行感知测量。
步骤102，响应于所述感知会话建立发起消息帧，建立与第一站点设备STA之间的无线局域网WLAN感知测量。
AP响应所述感知会话建立发起消息帧，建立与第一站点设备STA之间的WLAN感知测量；第一STA即感知测量的响应端，这样，WLAN感知过程中，在发起端设备为STA的情况下，由于STA无法与响应端进行一对多通信，而AP代理发起端设备进行感知测量可以实现一对多通信，减少STA作为发起端进行WLAN感知时造成的频谱资源浪费以及时延。
本公开实施例中，AP接收发起端设备发送的感知会话建立发起消息帧，并响应于所述感知会话建立发起消息帧，建立与第一站点设备STA之间的无线局域网WLAN感知测量；通过AP代理发起端设备进行WLAN感知测量，实现STA作为发起端时与响应端之间的一对多通信。本公开实施例解决了STA作为感知发起端，造成频谱资源浪费以及时延增加的问题。
作为第二示例，参见图5，图5示出了本公开实施例的一种应用场景；其中，STA作为SensingInitiator，AP作为代理端(proxy)与STA1至STAn进行多连接下的WLAN感知测量；STA1至STAn为感知会话的响应端。如图5中所示，主要包括以下步骤：
第1步，STA向AP发送感知会话建立发起消息(Sensing Session setup  request)；
第2步，AP反馈ACK消息。
此后，AP执行第3-1步以及3-2步，分别与多个STA之间建立WLAN感知测量(Sensing measurement setup)。
第4步，AP向STA发送感知会话建立响应(Sensing session setup response)。
第5步，AP与多个响应端之间进行感知测量并生成测量报告(Measurement procedure and measurement report)。
第6步，AP向STA发送测量报告。
在一个可选实施例中，所述接收发起端设备发送的感知会话建立发起消息帧之后，所述方法包括：
向所述发起端设备反馈确认ACK消息，所述ACK消息指示所述AP接收到所述感知会话建立发起消息帧。
在AP接收到感知会话建立发起消息帧之后，向发起端设备反馈确认ACK消息，如图5中第2步所示，AP向发起端设备反馈确认ACK消息，ACK消息标识AP已接收到发起端设备发送的感知会话建立发起消息帧。
在一个可选实施例中，所述感知会话建立发起消息帧中包括第一参数信息，所述第一参数信息包括以下至少一项：
带宽信息、NSS数量信息、周期信息、测量设备信息、指示所述AP接收反馈消息的第一超时信息、指示所述AP发送响应消息的第二超时信息、感知类型信息、指示所述发起端设备是否参与感知测量的第一指示信息。
其中，带宽信息指示WLAN感知测量所需要的带宽，例如在7GHz以下的频谱，带宽为20MHz、40MHz、80MHz、160MHz或320MHz等等，在60GHz频谱中，带宽为2160MHz、4320MHZ、6480MHz或8640MHz等等；NSS指示WLAN感知测量的空间流数(Number Of Spatial Stream)，其中标识发送或接收的NDP(Nulldatapacket)的空间流数量，例如NSS 为2或3等等；周期信息指示WLAN感知测量的测量周期的信息；第一超时信息指示所述AP接收反馈消息的时间信息，在第一超时信息内的时间里，AP接收反馈消息；可选地，上述参数可以来自于上层应用的指示。例如为20秒左右。
第二超时信息指示所述AP发送响应消息的超时信息；在第二超时信息指示的时间内，AP发送响应消息；可选地，第二超时信息可由AP设定。例如为200毫秒；可选地，第二超时信息小于第一超时信息。
感知类型信息指示本次WLAN感知为上行感知或下行感知，即TB-based基于触发感知测量或Non-TBbased基于非触发感知测量。
第一指示信息指示所述发起端设备是否参与感知测量，也即所述发起端设备也可以参与所述WLAN感知测量。
在一个可选实施例中，在所述第一参数信息包括所述感知类型信息的情况下，所述响应于所述感知会话建立发起消息帧，建立与第一站点设备STA之间的无线局域网WLAN感知测量，包括：
根据所述感知类型信息中指示的感知测量类型，建立与第一STA之间的WLAN感知测量；所述感知类型包括上行感知或下行感知。
可选地，若感知类型为下行感知，则感知测量完成之后，发起端设备向每个第一STA分别发送空数据包通告(Null Data Packet Announcement，NDPA)帧，并向第一STA发送NDP，发送trigger帧接收第一STA的测量感知反馈或第一STA根据NDPA帧中的资源反馈测量感知反馈；若感知类型为上行感知，则感知测量完成之后，发起端设备向每个第一STA分别发送NDPA帧之后再第一STA分别发送触发帧，并接收第一STA发送NDP。
在一个可选实施例中，在所述第一参数信息包括所述第一指示信息的情况下，且所述第一指示信息指示所述发起端设备参与感知测量，则第一STA包括所述发起端设备，作为第三示例，参见图6，图6示出了本公开 实施例的另一种应用场景；其中，STA作为Sensing Initiator，AP作为代理端(proxy)与STA1至STAn进行多连接下的WLAN感知测量；STA1至STAn为感知会话的响应端，且STA也作为响应端参与感知测量。如图6中所示，主要包括以下步骤：
第1步，STA向AP发送感知会话建立发起消息(Sensing Session setup request)；
第2步，AP反馈ACK消息。
此后，AP执行第3-1步以及3-2步，分别与多个STA(STA1-STAn)之间建立WLAN感知测量(Sensing measurement setup)。
以及，AP执行第3-3步，与发起端STA之间建立WLAN感知测量。
第4步，AP向STA发送感知会话建立响应(Sensing session setupresponse)。
第5步，AP与多个响应端之间进行感知测量并生成测量报告(Measurement procedure and measurement report)。
第6步，AP向STA发送测量报告。
在一个可选实施例中，所述建立与第一站点设备STA之间的无线局域网WLAN感知测量之后，所述方法包括：
向所述发起端设备发送感知会话响应；本公开实施例中，感知会话响应也可以是感知会话建立响应(Sensing session setupresponse)，如图5、图6中的第4步所示；
所述感知会话响应包括：状态标识码、时间同步功能参数和/或指示所述第一STA接收测量报告的时间信息。
其中，状态标识码(Status Code)用于指示AP的状态，例如：
所述状态标识码为第一参数值时指示所述AP接受所述感知会话建立发起消息帧以及所述第一参数信息；例如，第一参数值为“11”标识AP接受感知会话建立发起消息帧，且接收第一参数信息中STA感知测量的参数配置。
所述状态标识码为第二参数值时指示所述AP可执行所述WLAN感知测量且所述WLAN感知测量包括第二参数信息；例如，第二参数值为“10”标识AP可进行WLAN sensing测量，但携带了其他的第二参数信息，第二参数信息例如满足第一参数信息中参数配置要求的其他参数配置情况。例如，第一参数信息中对带宽的要求为20M，而第二参数信息中提供的带宽为40M，则AP可进行WLAN sensing测量且提供了新的参数配置情况。
所述状态标识码为第三参数值时指示所述AP拒绝执行所述WLAN感知测量，例如第三参数值为“00”标识AP无法进行WLAN sensing测量，例如无法满足第一参数信息的要求。
可选地，所述时间同步功能参数(Time Synchronization Function，TSF)指示所述发起端设备进入省电状态，并在进入苏醒态(awake)接收所述AP发送的所述测量报告；AP需反馈TSF参数信息给STA，以便STA在接收到ACK帧后能够进入PS状态，且在后续苏醒接收AP反馈的测量报告。
在一个可选实施例中，所述向所述发起端设备发送感知会话响应之后，所述方法包括：
执行所述WLAN感知测量，并生成所述测量报告；如图5、图6中的第5步所示，AP与多个响应端之间进行感知测量并生成测量报告；
向所述发起端设备发送所述测量报告，如图5、图6中的第6步所示，AP向STA发送测量报告。
在一个可选实施例中，所述感知会话建立发起消息帧中包括所述感知会话建立发起消息帧的第一标识，用于标识本次感知会话；可选地，所述第一标识可以是上层应用(例如APP)的标识。
在一个可选实施例中，所述AP为所述发起端设备的建立关联AP或 非关联AP。
如图2所示，响应端1、响应端2和响应端3可以分别与发起端具有关联关系(associated)或不具有关联关系(unassociated)。其中，“关联”可以指感知发起端与感知响应端之间建立了用于通信的关联连接，“非关联”可以指感知发起端与感知响应端之间未建立用于通信的关联连接。
本公开实施例中，AP接收发起端设备发送的感知会话建立发起消息帧，并响应于所述感知会话建立发起消息帧，建立与第一站点设备STA之间的无线局域网WLAN感知测量；通过AP代理发起端设备进行WLAN感知测量，实现STA作为发起端时与响应端之间的一对多通信。
如图7所示，本公开实施例还提供了一种WLAN感知方法，可选地，所述方法可应用于发起端(即感知发起端)，所述方法包括以下步骤：
步骤701，确定感知会话建立发起消息帧。
作为第一示例，参见图2至图4，介绍本公开实施例提供的WLAN感知方法所应用的WLAN Sensing的架构以及WLAN Sensing过程，具体内容参见前述实施例，在此不再赘述。

步骤702，向接入点设备AP发送感知会话建立发起消息帧，指示所述AP建立与第一站点设备STA之间的无线局域网WLAN感知测量。
发起端设备向AP发送感知会话建立发起消息帧，使得AP建立与第一站点设备STA之间的WLAN感知测量；第一STA即感知测量的响应端，这样，WLAN感知过程中，在发起端设备为STA的情况下，由于STA无法与响应端进行一对多通信，而AP代理发起端设备进行感知测量可以实现一对多通信，减少STA作为发起端进行WLAN感知时造成的频谱资 源浪费以及时延。
本公开实施例中，发起端设备确定并向AP发送感知会话建立发起消息帧，指示AP建立与第一站点设备STA之间的无线局域网WLAN感知测量；通过AP代理发起端设备进行WLAN感知测量，实现STA作为发起端时与响应端之间的一对多通信。本公开实施例解决了STA作为感知发起端，造成频谱资源浪费以及时延增加的问题。
