Description

通信方法及装置、电子设备及存储介质 技术领域
本公开实施例涉及移动通信技术领域，具体而言，本公开实施例涉及一种通信方法及装置、电子设备及存储介质。
背景技术
随着移动通信技术的迅速发展，无线保真(Wireless Fidelity，Wi-Fi)技术在传输速率以及吞吐量等方面已经取得了巨大的进步。目前，Wi-Fi技术所研究的内容例如320Mhz的带宽传输、多个频段的聚合及协同等，其主要的应用场景例如视频传输、增强现实(Augmented Reality，AR)、虚拟现实(Virtual Reality，VR)等。
在目前所研究的Wi-Fi技术中，可能会支持无线局域网(Wireless Local Area Network，WLAN)感知(Sensing)技术。例如，在密集环境下(例如家庭环境及企业环境)的位置发现、接近检测(Proximity Detection)及存在检测(Presence Detection)等应用场景。在WLAN Sensing的过程中，站点设备(Station，STA)和接入点设备(Access Point，AP)的身份通常可以互换，例如二者均可以作为发起端设备(Sensing Initiator或Sensing Transmitter)；作为Sensing Initiator或Sensing Transmitter时，AP可以同时和多个STA进行通信，但STA不具备上述功能，只能与单个响应端(Sensing Responder)之间一对一通信，一方面造成频谱资源浪费，另一方面造成时延增加，对于时延要求较高的通信场景，可能无法满足时延要求。为了解决该问题，提出了用AP代理STA进行WLAN感知测量的方式；AP代理STA进行感知测量后，需要向STA反馈测量结果；因此，需要提供一种AP向STA反馈测量结果的方式。

本公开实施例提供了一种通信方法及装置、电子设备及存储介质，用以提供一种AP代理STA进行WLAN感知测量的场景中，AP向STA反馈测量结果的方式。
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通信方法，可选地，所述方法可应用于发起端设备，所述发起端设备可以是STA；为了便于说明，后续用requesting STA表示所述发起端设备，可以理解的是，这并不构成对本公开实施例的限定。
该方法可以包括以下步骤：
步骤101，发送第一无线帧；其中，所述第一无线帧中包括第一时间信息；所述第一时间信息指示代理接入点设备AP反馈感知测量结果的超时时间信息；所述感知测量结果包括代理AP代理所述发起端设备建立无线局域网WLAN感知测量的测量结果。
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通信 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(或发起端，即requesting STA)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)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(STA)或接入点设备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。
通常情况下，在作为Sensing Initiator或Sensing Transmitter时，STA不具备和多个接收端同时进行通信的功能，因此需要代理端设备(例如AP)代理STA进行感知测量。在AP代理requesting STA(即请求AP代理其进行感知测量的STA)进行感知测量的场景中，STA发送第一无线帧，在第一无线帧中指示AP向STA反馈测量结果的时间，即指示了requesting STA接收感知结果的时间；第一无线帧可以是代理感知(Sensing By Proxy，SBP)请求帧，或者在感知测量建立过程中与AP协商的消息帧。
具体地，所述第一无线帧中包括第一时间信息；所述第一时间信息指示代理接入点设备AP反馈感知测量结果的超时时间信息；所述感知测量 结果包括代理AP代理所述发起端设备建立无线局域网WLAN感知测量的测量结果；例如，超时时间信息可以是超时间隔元素(Timeout Interval Element，TIE)或时延元素(Timeout)；第一时间信息指示ProxyAP在完成代理感知测量之后，在第一时间信息所指示的时间内，将感知测量结果反馈给requesting STA，以满足requesting STA的时延需求，完善WLAN感知测量流程。
本公开实施例中，发起端设备发送第一无线帧，在第一无线帧中携带第一时间信息，所述第一时间信息指示代理AP反馈感知测量结果的超时时间信息。本公开实施例提供了一种AP代理STA进行WLAN感知测量的场景中反馈测量结果的方式。
在一个可选实施例中，所述第一时间信息包括：所述代理AP建立WLAN感知测量的时延信息，或所述代理AP反馈感知测量结果的超时时间信息。时延信息例如TIE元素，Requesting STA可在与proxy AP在建立代理感知测量的过程中，携带TIE元素；作为第二示例，TIE元素的帧格式如以下表1所示：
表1：
Figure PCTCN2022074835-appb-000001
表1中，TIE元素包括4个子元素，Element ID、Length、Timeout Interval type分别占据1个字节，Timeout Interval Value占据4个字节。
其中，Timeout Interval Type域指示Timeout Interval的类型，timeout interval value域指示timeout interval Type域的值。当类型指示第一时间信息(或requesting STA接收反馈结果的时间信息)的类型时，其指示第一时间信息的具体的时间，单位为时间单位(Time Unit，TU)。
如表2所示，timeout interval value内不同的值的含义如下：
表2：
Figure PCTCN2022074835-appb-000002
其中，以Timeout Interval Type为1为例，其指示重新关联期限间隔。Timeout Interval Type的值域的第5至255目前为保留状态，可以在其中选择一个值用来指示第一时间信息，例如选择5来标识。
如图5中所示，本公开实施例提供了一种通信方法，可选地，所述方法可应用于发起端设备，所述发起端设备可以是STA；为了便于说明，后续用requesting STA表示所述发起端设备。
该方法可以包括以下步骤：
步骤501，发送第一无线帧；其中，所述第一无线帧中包括第一时间信息；所述第一时间信息指示代理接入点设备AP反馈感知测量结果的超时时间信息；所述感知测量结果包括代理AP代理所述发起端设备建立无线局域网WLAN感知测量的测量结果。
在AP代理requesting STA(即请求AP代理其进行感知测量的STA)进行感知测量的场景中，STA发送第一无线帧，在第一无线帧中指示AP 向STA反馈测量结果的时间，即指示了requesting STA接收感知结果的时间；第一无线帧可以是感知代理(Sensing By Proxy，SBP)请求帧，或者在感知测量建立过程中与AP协商的消息帧。
具体地，所述第一无线帧中包括第一时间信息；所述第一时间信息指示代理接入点设备AP反馈感知测量结果的超时时间信息；所述感知测量结果包括代理AP代理所述发起端设备建立无线局域网WLAN感知测量的测量结果；第一时间信息指示AP在完成代理感知测量之后，在第一时间信息所指示的时间内，将感知测量结果反馈给requesting STA。
步骤502，接收第二无线帧；其中，所述第二无线帧中包括第二时间信息；所述第二时间信息指示所述代理AP反馈感知测量结果的时间信息；所述第二时间信息在所述第一时间信息的范围内。
可选地，第二无线帧可以是SBP response帧；Proxy AP根据第一时间信息，在回复给requesting STA的第二无线帧中携带第二时间信息；第二时间信息指示Proxy AP反馈感知测量结果的时间信息；其中，所述第二时间信息在所述第一时间信息的范围内，即Proxy AP在requesting STA指定的时间内反馈感知测量结果，以满足requesting STA的时延需求，完善WLAN感知测量流程。
可选地，本公开实施例中，所述第二时间信息包括时刻信息或时间区间信息。时刻信息即时间点信息，例如，Proxy AP在接收到第一无线帧之后即刻反馈感知测量结果；时间区间信息即时间段信息，例如，Proxy AP在接收到第一无线帧之后在时间区间内反馈感知测量结果。
可选地，本公开实施例中，在所述发起端设备与所述代理AP之间不存在通信连接的情况下，所述第二无线帧中还包括所述代理AP的时间同步功能参数TSF信息，即requesting STA未与proxy AP建立初始关联(关联即通信连接)，则第二无线帧中还包括proxy AP的间同步功能参数信息(Time Synchronization Function，TSF)信息，使得requesting STA与proxy AP保持时间同步。
在一个可选地实施例中，所述第一无线帧包括：代理感知请求帧或感知消息帧；例如，requesting STA参与感知测量，则requesting STA在代理感知请求帧SBP中携带第一时间信息；
若requesting STA未参与感知测量，则requesting STA在所述感知消息帧中携带第一时间信息，感知消息帧包括：所述代理AP代理所述发起端设备建立无WLAN感知测量过程中的消息帧。

通常情况下，在作为Sensing Initiator或Sensing Transmitter时，STA不具备和多个接收端同时进行通信的功能，因此需要代理端设备(例如AP)代理STA进行感知测量。在AP代理requesting STA(即请求AP代理其进行感知测量的STA)进行感知测量的场景中，AP接收STA发送第一无线帧，在第一无线帧中指示AP向STA反馈测量结果的时间，即指示了requesting STA接收感知结果的时间；第一无线帧可以是代理感知 (Sensing By Proxy，SBP)请求帧，或者在感知测量建立过程中与AP协商的消息帧。
具体地，所述第一无线帧中包括第一时间信息；所述第一时间信息指示代理接入点设备AP反馈感知测量结果的超时时间信息；所述感知测量结果包括代理AP代理所述发起端设备建立无线局域网WLAN感知测量的测量结果；例如，超时时间信息可以是TIE元素或Timeout元素；Proxy AP在完成代理感知测量之后，在第一时间信息所指示的时间内，将感知测量结果反馈给requesting STA，以满足requesting STA的时延需求，完善WLAN感知测量流程。
本公开实施例中，Proxy AP接收第一无线帧，获取第一无线帧中携带的第一时间信息，所述第一时间信息指示代理AP反馈感知测量结果的超时时间信息。本公开实施例提供了一种AP代理STA进行WLAN感知测量的场景中反馈测量结果的方式。
在一个可选实施例中，所述第一时间信息包括：所述代理AP建立WLAN感知测量的时延信息，或所述代理AP反馈感知测量结果的超时时间信息。时延信息例如TIE元素，Requesting STA可在与proxy AP在建立代理感知测量的过程中，携带TIE元素；作为第二示例，TIE元素的帧格式如以下表1所示：
