本公开实施例提供了一种WLAN感知测量方法及装置、电子设备及存储介质，用以提供一种参与感知测量的NDP帧的格式，以实现协作性的WLAN感知测量。
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感知测量方法，可选地，所述方法可应用于电子设备，所述电子设备可以是感知发起端，该方法可以包括以下步骤：
步骤101，发送空数据包通告NDPA帧，在所述NDPA帧中携带发射端的第一标识和/或接收端的第二标识；
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感知测量方法所应用的WLAN Sensing的架构以及WLAN Sensing过程。
图2示出了一种WLAN Sensing(过程)的架构示意图；其中，感知发起端Sensing Initiator(或发起端Initiator)发起WLAN Sensing感知测量(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)或响应端对其响应，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(Station，STA)或接入点设备(Access Point，AP)。此外，STA和AP可以在WLAN感知过程中承担多个角色；例如，在WLAN感知过程中，STA还可以作为感知发起者，感知发起者可能是感知发射端(Sensing Transmitter)、感知接收端(Sensing Receiver)，或两者都是，或都不是。在WLAN感知过程中，感知响应端也可能是感知发射端、感知接收端或两者都是。
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接入点设备(AP)进行通信；图4中Client1为感知发起端，Client2为感知响应端。
在协作性的感知测量场景中，AP作为Initiator与感知响应端建立感知测量，同时，也允许STA作为Transmitter发送参与感知测量的NDP帧至参与感知测量的其他STA和AP；具体地，作为第二示例，参见图5和图6，示出了协作性的感知测量的第一个实例；其中，图5中为测量信号传输过程，作为感知发起端的AP同时作为感知发射端；发起端传输信号，作为感知接收端的感知响应端1、感知响应端2接收信号；且发起端到两个响应端之间的信道可用。图6中为测量结果反馈过程，两个响应端分别将测量结果反馈给发起端。
作为第三示例，参见图7和图8，示出了协作性的感知测量的第二个实例；其中，图7中为测量信号传输过程，作为感知发射端的响应端1传输信号，作为感知接收端的感知发起端、感知响应端2接收信号；且响应端1到发起端、响应端1到响应端2之间的信道可用。图8中为测量结果反馈过程，响应端2将测量结果反馈给发起端。
在协作性的感知测量场景中，发起端首先发送空数据包通告(Null Data Packet Announcement，NDPA)帧，在所述NDPA帧中携带发射端的第一标识和/或接收端的第二标识，以图5中的实例为例，则NDPA帧中携带AP和响应端1、响应端2的标识信息。
步骤102，发送第一空数据包NDP帧，指示所述发射端在第二NDP帧中携带所述第二标识以及所述发起端的第三标识并发送所述第二NDP帧。
在发送NDPA帧之后，发起端发送第一NDP帧，第一NDP帧的接收方包括发射端和接收端；第一NDP帧指示所述发射端发送第二NDP帧，并在第二NDP中携带所述第二标识以及所述发起端的第三标识；可选地，第一NDP帧不参与感知测量过程。
作为第四示例，本公开实施例提供的WLAN感知测量方法的WLAN Sensing过程如图9所示，其中，AP为感知发起端，STA1为感知发射端，STA2为感知响应端(感知接收端)；
其中，第1步，AP首先向STA1和STA2分别发送NDPA帧，在所述NDPA帧中携带STA1的第一标识和/或STA2的第二标识。
第2步，AP向STA1和STA2分别发送第一NDP帧。
第3步，STA1分别向AP和STA2发送第二NDP帧，第二NDP帧中携带STA2的第二标识以及AP的第三标识。
参见图10，第3步的信号传输场景如图10中Q1中的场景所示，由STA1分别传输至AP以及STA2。
第4步，后续AP向STA2发送请求消息(request)，例如感知测量请求等；
第5步，STA2向AP反馈响应消息(response)，例如感知测量结果。
参见图10，第3步的信号传输场景如图10中Q2中的场景所示，感知测量结果由STA2直接传输至AP；关于STA 1的感知测量结果，通常情况下，AP不需要来自STA 1的明确的感知测量报告。若需要，则STA 1可在传输第一NDP帧之后传输，然后AP向STA2发送请求，由STA 2反馈在STA2的测量结果时，同时反馈STA 1的测量结果；如图10中箭 头S所示，STA1将测量结果发送至STA2，由STA2代为传输至AP。
本公开实施例中，发起端发送空数据包通告NDPA帧，在所述NDPA帧中携带发射端的第一标识和/或接收端的第二标识；然后发送第一空数据包NDP帧，指示所述发射端在第二NDP帧中携带所述第二标识以及所述发起端的第三标识并发送所述第二NDP帧，第二NDP帧参与感知测量，且第二NDP帧中包括所述第二标识以及所述第三标识。本公开实施例提供了一种参与感知测量的NDP帧的格式，以实现协作性的WLAN感知测量。
