具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。

请参考图1，其示出了本申请一个实施例提供的无线通信系统的示意图。如图1所示，该无线通信系统可以包括：接入点(Access Point，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之间通信，或者STA与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 of Things，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(45GHz、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，45GHz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。

一、WLAN感知(WLAN Sensing)及参与者
WLAN感知是指通过测量WLAN信号经过人或物散射和/或反射的变化来感知环境中的人或物的方法和应用。参与感知的WLAN终端可能有感知测量发起者，感知测量响应者，感知信号发送者，感知信号接收者等角色。在一些实施例中，参与WLAN感知的设备包括：感知发起设备(即感知测量发起者)和感知响应设备(即感知测量响应者)。或者，参与WLAN感知的设备包括：感知发送设备(即感知信号发送者)和感知接收设备(即感知信号接收者)。
图2的(1)至(6)示出了本申请一个示例性实施例提供的6种基于感知信号进行WLAN感知的典型场景。
在示例性实施例中，WLAN感知可以是一个站点将感知信号发送给另一个站点的单向交互过程。如图2的(1)所示，WLAN感知是站点2将感知信号发送给站点1。
在示例性实施例中，WLAN感知可以是两个站点之间的交互过程。如图2的(2)所示，WLAN感知是站点1向站点2发送感知信号、站点2向站点1发送测量结果。
在示例性实施例中，WLAN感知可以是多个单向信息交互过程的组合。如图2的(3)所示，WLAN感知是站点3将感知信号发送至站点2，站点2将测量配置发送至站点1。
在示例性实施例中，WLAN感知可以是多个站点分别向同一个站点发送感知信号。如图2的(4)所示，WLAN感知是站点2和站点3分别向站点1发送感知信号。
在示例性实施例中，WLAN感知可以是一个站点与其他多个站点分别进行信息交互。如图2的(5)所示，WLAN感知是站点1将感知信号分别发送至站点2和站点3，站点2和站点3分别将测量配置发送至站点1。
在示例性实施例中，如图2的(6)所示，WLAN感知是多个站点(如站点3和站点4)分别将感知信号发送至站点2，站点2将测量结果发送至站点1。
图3的(1)至(4)示出了本申请一个示例性实施例提供的4种基于感知信号以及反射信号进行WLAN感知的典型场景。
在示例性实施例中，如图3的(1)所示，站点1发出的感知信号碰到感知对象，感知对象反射感知信号，站点1接收反射信号。
在示例性实施例中，如图3的(2)所示，站点2发出的感知信号碰到感知对象，感知对象反射感知信号，站点2接收反射信号。
在示例性实施例中，如图3的(3)所示，站点1和站点2分别发出的感知信号都碰到了感知对象，感知对象分别反射站点1和站点2发出的感知信号，站点1和站点2分别接收感知对象反射的信号，站点2将测量结果发送至站点1(即站点之间同步共享测量结果)。
在示例性实施例中，如图3的(4)所示，站点3和站点2分别发出的感知信号都碰到了感知对象， 感知对象分别反射站点3和站点2发出的感知信号，站点3和站点2分别接收感知对象反射的信号，站点3将测量结果分别发送至站点1和站点2、站点2也将测量结果发送至站点1(即站点之间同步共享测量结果)。
二、WLAN感知测量总体流程
如图4所示，WLAN感知测量包括以下一个或多个阶段：感知发现阶段41、测量建立阶段42、感知测量阶段43、感知上报阶段44以及测量终止阶段45。同一个WLAN终端在一个感知测量中可能有一个或多个角色，例如感知发起设备可以仅仅是感知发起设备，也可以成为感知发送设备，也可以成为感知接收设备，还可以同时是感知发送设备和感知接收设备。
感知发现阶段：用于发起感知测量。
测量建立阶段：建立感知测量，确定感知测量参与设备及其角色(包括感知发送设备和感知接收设备)，决定感知测量相关的操作参数，并且可选的在终端之间交互该参数。
感知测量阶段：实施感知测量，感知发送设备发送感知信号给感知信号接收者。
感知上报阶段：上报测量结果，由应用场景决定，感知接收设备可能需要给感知测量发起设备上报测量结果。
测量终止阶段：终端停止测量，终止感知测量。
三、WLAN感知测量参数协商
如图5所示，感知测量建立时，终端间可能需要一一协商感知角色和操作参数，或者终端声明自身的角色和操作参数(例如通过信标帧或者其他特殊帧)。如感知站点(Sens STA)1、感知站点2和感知站点3通过感知请求和感知响应，协商感知角色和操作参数。可选地，感知站点1为感知发起设备或感知发送设备，感知站点2为感知响应设备或感知接收设备，感知站点3为感知响应设备或感知发送设备。
四、测量设置与测量实例
如图6所示，感知测量发起者可以设置多组测量参数61，一组测量参数(用Measurment Setup ID(测量设置ID)61来标识，可以等价于Burst Group)可以应用于多次测量(用Measurement Instance ID来标识，可以等价于Burst)。
五、non-TB(Non-Trigger Based，非基于触发的)测量流程
在一些实施例中，如图7所示，只有一对设备进行感知测量，即采用non-TB测量流程。感知发起设备发送NDPA帧(NDP Announcement，测量宣告帧)来宣告测量开始，在SIFS时间后发送I2R(Initiator to Responder，发起设备到响应设备)NDP帧；感知响应设备接收该NDP帧并在SIFS时间后发送R2I(Responder to Initiator，响应设备到发起设备)NDP帧。根据测量设置中确定的角色，两个设备进行不同的处理。若感知发起设备仅是感知信号发送设备，则感知响应设备仅是感知信号接收设备，该情况下感知响应设备接收到I2R NDP帧后产生感知测量结果。若感知发起设备仅是感知信号接收设备，则感知响应设备仅是感知信号发送设备，该情况下感知发起设备接收到R2I NDP帧后产生感知测量结果。若感知发起设备既是感知信号发送设备又是感知信号接收设备，则感知响应设备也既是感知信号接收设备又是感知信号发送设备，该情况下两者(即感知发起设备和感知响应设备)都可以产生感知测量结果。
六、TB(Trigger Based，基于触发的)测量流程
在一些实施例中，如图8所示，有多个(多于两个)设备参与感知测量，为提高效率，一般采用TB测量流程。在轮询(Polling)阶段，AP发送轮询触发帧(Sensing Polling TF)来探测感知参与设备是否参与感知测量。在触发帧测量(TF sounding)阶段，AP发送触发帧触发站点发送NDP帧。在NDPA测量(NDPA sounding)阶段，AP发送NDPA帧和NDP帧。
在一些实施例中，如图9所示，感知发送设备发送NDP帧后发送反馈触发帧，感知信号接收设备接收该触发帧后给感知信号发送设备上报测量结果。
在感知测量中，测量结果是由感知发起设备显式请求(如由感知反馈请求帧或者感知上报触发帧触发)或者隐式请求上报(如由NDP触发)的。测量结果可以立即上报(immediate report)或者延迟上报(delayed report)，延迟上报一般由感知发起设备显式请求。
本申请实施例涉及的一些名词介绍如下：
关联标识符(Association Identifier，AID)：用于标识跟接入点建立关联后的终端。
媒体访问控制(Medium Access Control，MAC)：媒体访问控制协议，或媒体访问控制地址的简称。

参与WLAN感知的WLAN设备可能包括如下角色(role)：
感知发起设备(Sensing Initiator)，发起感知测量(sensing measurement)并想要获知感知结果的设备；

感知处理设备(Sensing processor)，处理感知测量结果的设备；
感知参与设备(Sensing Participant)，包括感知发起设备、感知信号发送设备和感知信号接收设备。
WLAN终端在一个感知测量中可能有一个或多个角色，例如感知发起设备可以仅仅是感知发起设备，也可以成为感知信号发送设备，也可以成为感知信号接收设备，还可以同时是感知信号发送设备和感知信号接收设备。
请参考图10，其示出了本申请一个实施例提供的感知测量方法的流程图。该方法可以包括如下步骤(1001～1002)：
步骤1001，代理发起设备向代理响应设备发送代理请求帧，代理请求帧用于请求代理响应设备代理执行感知测量。
在一些实施例中，代理发起设备通过向代理响应设备发送代理请求帧，代理响应设备在接收到代理请求帧之后发起感知测量。也即，代理发起设备通过代理响应设备发起感知测量。
在一些实施例中，代理发起设备需要给代理响应设备指示感知需求信息，代理响应设备从而根据感知需求信息生成对应的感知测量设置信息，并找到合适的感知响应设备建立感知测量过程。可选地，代理请求帧中携带的信息即为感知需求信息。
可选地，感知测量是WLAN感知。
在一些实施例中，代理发起设备可以是智能手机、可穿戴设备等感知测量功能欠佳的设备；代理响应设备可以是无线路由器等感知测量功能较佳的设备。
当然，代理发起设备还可以是PC(Personal Computer，个人计算机)、平板电脑、智能电视、智能机器人等终端设备，本申请实施例对此不作具体限定。代理响应设备还可以是微型基站、可移动基站、电视等设备，本申请实施例对此不作具体限定。
步骤1002，代理发起设备接收代理响应设备发送的代理响应帧。
本申请可以在代理发起设备发起请求后，由代理响应设备代理执行感知测量过程，然后向代理发起设备上报感知测量的测量结果。
综上所述，本申请实施例提供的技术方案中，代理发起设备通过向代理响应设备发送代理请求帧，以使得代理响应设备根据该代理请求帧发起感知测量，使得代理发起设备无需亲自发起感知测量，从而降低了对代理发起设备的设备参数的要求，扩展了感知测量的应用范围。
在一些实施例中，代理请求帧通过字段(如字段的值)携带信息。其中，字段也可以称为指示位。
在一些实施例中，如图11所示，代理请求帧为一种新的行动帧(Action frame)或无确认行动帧(Action No Ack)。其中，行动类别(Category)字段的值为4，表示该帧为公共行动帧(Public Action frame)；公共行动子类(Public Acton Field)字段的值为53(公共行动子类的值可以为51～255范围内的任意数值)表示该帧为代理请求帧。
在一些实施例中，代理请求帧是受保护的帧。可选地，代理请求帧中的行动类别字段的值为9，表示该帧为受保护的双重公共行动帧类型(Protected Dual of Public Action)；公共行动子类字段的值为33(公共行动子类的值可以为33～255范围内的任意数值)表示该帧为受保护的感知代理请求帧。
在一些实施例中，代理请求帧携带有如下信息中的至少一种：
(1)是否要求代理响应设备获取感知测量的感知测量结果
在一些实施例中，代理发起设备若需要代理响应设备获取感知测量结果，则需要在向代理响应设备发送的代理请求帧中携带表示“要求代理响应设备获取感知测量的感知测量结果”的信息。可选地，代理响应设备在获取到感知测量结果后，再将感知测量结果发送给代理发起设备。
在一些实施例中，感知信号接收设备在感知测量过程中所产生的测量结果可以不直接使用IEEE 802.11协议的帧来进行传输，而是交由感知信号接收设备中的上层应用进行处理后、使用上层通信协议或者带外方式进行传输。这样，代理响应设备可能无法获取感知测量的感知测量结果。因而，代理发起设备可以不需要代理响应设备获取感知测量结果。若代理发起设备不需要代理响应设备获取感知测量结果，则需要在向代理响应设备发送的代理请求帧中携带表示“不要求代理响应设备获取感知测量的感知测量结果”的信息。
在一些实施例中，如图11所示，通过是否获取测量结果(Obtain Report)指示位，指示是否要求代理响应设备获取感知测量的感知测量结果。在一些实施例中，是否获取测量结果指示位的值若为1，表示要求代理响应设备获取感知测量的感知测量结果；是否获取测量结果指示位的值若为0，表示不要求代理响应设备获取感知测量的感知测量结果。在一些实施例中，是否获取测量结果指示位的值若为0，表示要求代理响应设备获取感知测量的感知测量结果；是否获取测量结果指示位的值若为1，表示不要求代理响应设备获取感知测量的感知测量结果。
在一些实施例中，代理请求帧可以隐式地指示“要求代理响应设备获取感知测量的感知测量结果”的信息。例如，代理请求帧中若没有表示“是否要求代理响应设备获取感知测量的感知测量结果”的显示指示信息，即表示“要求代理响应设备获取感知测量的感知测量结果”；这种情况下，只有在代理请求帧中显示地指示“不要求代理响应设备获取感知测量的感知测量结果”，才能够表示不要求代理响应设备获取感知测量的感知测量结果。
在一些实施例中，代理请求帧可以隐式地指示“不要求代理响应设备获取感知测量的感知测量结果”的信息。例如，代理请求帧中若没有表示“是否要求代理响应设备获取感知测量的感知测量结果”的显示指示信息，即表示“不要求代理响应设备获取感知测量的感知测量结果”；这种情况下，只有在代理请求帧中显示地指示“要求代理响应设备获取感知测量的感知测量结果”，才能够表示要求代理响应设备获取感知测量的感知测量结果。
(2)对感知测量结果的精度要求
在一些实施例中，从多个精度等级中确定一个精度等级，并将该精度等级作为对感知测量结果的精度要求。可选地，精度可以按照高精度、中等精度、低精度划分为三个精度等级。
当然，精度等级还可以按照其他形式进行划分，本申请实施例对精度等级的数量、精度等级的划分方式不作具体限定。
在一些实施例中，如图11所示，通过精度要求(Accuracy Class)字段指示对感知测量结果的精度要求。例如，精度分为高精度、中等精度、低精度划分为三个精度等级。在一些实施例中，精度要求字段的值为0表示高精度，精度要求字段的值为1表示中等精度，精度要求字段的值为2表示低精度。在另一些实施例中，精度要求字段的值为0表示低精度，精度要求字段的值为1表示中等精度，精度要求字段的值为2表示高精度。
在一些实施例中，对感知测量结果的精度要求，可以根据代理发起设备对感知测量的需求确定。例如，在人体运动较为激烈的体感游戏场景中，代理发起设备需要通过感知测量获取人体的位置和运动情况以调整游戏节奏，则代理发起设备对感知测量结果的精度要求就会较高(如设置为上述的高精度)。又例如，若宠物主想要了解家中的宠物猫是在家，较低的测量精度就可以获取到较为准确的结果(即宠物猫是否在家)，那么代理发起设备对感知测量结果的精度要求可以设置得较低(如设置为上述的低精度)。
(3)代理发起设备在感知测量中的角色
代理发起设备可以参与感知测量，也可以不参与感知测量。在一些实施例中，代理发起设备在感知测量中的角色包括如下任意一种：
感知信号发送设备；
感知信号接收设备；
感知信号发送设备和感知信号接收设备；
未指定角色(not specified)；
不参与感知测量。
在一些实施例中，代理发起设备通过代理请求帧指示自身在感知测量中的具体角色，如代理发起设备指示自身在感知测量中是感知信号发送设备、还是感知信号接收设备、还是感知信号发送设备和感知信号接收设备、还是不参与感知测量，代理响应设备发起感知测量设置时按该指示执行。
在一些实施例中，代理发起设备未在代理请求帧指示自身在感知测量中的具体角色，或者对于自身在感知测量中的指示为“未指定角色”，则表示代理发起设备对自身在感知测量中的具体角色不作具体要求，而是由代理响应设备决定代理发起设备在感知测量中承担哪种角色。也即，未指定角色可以指没有指定代理发起设备作为感知信号发送设备、也没有指定代理发起设备作为感知信号接收设备、也没有指定代理发起设备作为感知信号发送设备和感知信号接收设备、也没有指定代理发起设备不参与感知测量；而是由代 理响应设备决定代理发起设备在感知测量中是作为感知信号发送设备，还是作为感知信号接收设备，还是作为感知信号发送设备和感知信号接收设备，还是不参与感知测量。其中，不参与感知测量是指不作为感知信号发送设备和/或感知信号接收设备参与感知测量。
可选地，在代理发起设备不参与感知测量的情况下，由代理响应设备发起感知测量设置时不会包含该代理发起设备。
在一些实施例中，如图11所示，通过角色字段指示代理发起设备在感知测量中的角色。
在一些实施例中，角色字段的值为0，表示代理发起设备在感知测量中作为感知信号发送设备(sensing transmitter)；角色字段的值为1，表示代理发起设备在感知测量中作为感知信号接收设备(sensing receiver)；角色字段的值为2，表示代理发起设备在感知测量中作为感知信号发送设备和感知信号接收设备(sensing transmitter and receiver)；角色字段的值为3，表示代理发起设备可以在感知测量中参与感知测量但不指定具体角色，即由代理响应设备决定代理发起设备在感知测量中是哪种角色；角色字段的值为4，表示代理发起设备不参与感知测量(not participate)。
在另一些实施例中，角色字段的值为4，表示代理发起设备在感知测量中作为感知信号发送设备；角色字段的值为3，表示代理发起设备在感知测量中作为感知信号接收设备；角色字段的值为2，表示代理发起设备在感知测量中作为感知信号发送设备和感知信号接收设备；角色字段的值为1，表示代理发起设备在感知测量中可以参与感知测量但不指定具体角色，即由代理响应设备决定代理发起设备在感知测量中是哪种角色；角色字段的值为0，表示代理发起设备不参与感知测量。
(4)是否要求在不同的感知测量实例中的感知信号发送设备和感知信号接收设备保持一致
在一些实施例中，感知信号发送设备和感知信号接收设备是否保持一致，是指不同感知测量实例中的感知信号发送设备是否相同、不同感知测量实例中的感知信号接收设备是否相同。例如，若每个感知测量实例中都是STA1和STA2这两个站点作为感知信号发送设备，则意味着在不同的感知测量实例中的感知信号发送设备保持一致；若每个感知测量实例中都是STA1、STA3和STA4这三个站点作为感知信号接收设备，则意味着在不同的感知测量实例中的感知信号接收设备保持一致。又例如，若感知测量实例1中是STA1和STA2这两个站点作为感知信号发送设备、而感知测量实例2中仅由STA1这一个站点作为感知信号发送设备，则意味着在感知测量实例1和感知测量实例2中感知信号发送设备不一致；若感知测量实例1中是STA1和STA3这两个站点作为感知信号接收设备、而感知测量实例2中是STA3和STA4这两个站点作为感知信号接收设备，STA2在感知测量实例2不参与测量，则意味着在感知测量实例1和感知测量实例2中感知信号接收设备不一致。
在一些实施例中，如图11所示，通过固定感知信号发送和接收设备(Fixed TX-RX)字段，指示是否要求在不同的感知测量实例中的感知信号发送设备和感知信号接收设备保持一致。在一些实施例中，固定感知信号发送和接收设备字段的值为1，表示要求在不同的感知测量实例中的感知信号发送设备和感知信号接收设备保持一致；固定感知信号发送和接收设备字段的值为0，表示不要求在不同的感知测量实例中的感知信号发送设备和感知信号接收设备保持一致。在另一些实施例中，固定感知信号发送和接收设备字段的值为0，表示要求在不同的感知测量实例中的感知信号发送设备和感知信号接收设备保持一致；固定感知信号发送和接收设备字段的值为1，表示不要求在不同的感知测量实例中的感知信号发送设备和感知信号接收设备保持一致。
(5)是否要求在感知测量中使用受保护的管理帧
通过对帧信息进行加密可以保护管理帧，从而提升针对管理帧的数据传输的隐私性和安全性。在一些实施例中，代理请求帧可以指示感知测量中使用的管理帧是否需要加密。
在无线通信过程中，数据帧一般为受保护(即经过加密)的帧；控制帧一般不进行保护(即不加密)；而对于管理帧，可以进行保护也可以不保护。可见，数据帧、控制帧是否需要保护一般是确定的，管理帧是否需要保护是不太确定的，因而需要通过代理请求帧指示管理帧是否需要受保护。
在一些实施例中，如图11所示，通过是否保护(Protected)字段指示是否要求在感知测量中使用受保护的管理帧。在一些实施例中，是否保护字段的值为1，表示要求在感知测量中使用受保护的管理帧；是否保护字段的值为0，表示不要求在感知测量中使用受保护的管理帧。在另一些实施例中，是否保护字段的值为0，表示要求在感知测量中使用受保护的管理帧；是否保护字段的值为1，表示不要求在感知测量中使用受保护的管理帧。
(6)感知测量结果的类型
可选地，通过代理请求帧指示感知参与设备通过感知测量需要获取的感知测量结果的类型。
在一些实施例中，感知测量结果的类型包括：信道状态信息(CSI，Channel State Information)、信道状态信息中的幅度信息(CSI Amplitude only)、信道状态信息中的相位信息(CSI Phase only)、波束信噪比、信号到达角度信息(AoA，Angle of Arrival)、信号出发角度信息(AoD，Angle of Departure)、多普勒信息(Doppler) 等等。可选地，信道状态信息包括信道频率响应(CFR，Channel Frequency Response)。
在一些实施例中，如图11所示，通过测量结果类型(Measurement Report Type)字段指示请求代理建立的测量设置中的感知测量结果的类型。在一种实施例中，测量结果类型字段的值为0，表示感知测量结果的类型为信道状态信息；测量结果类型字段的值为1，表示感知测量结果的类型为波束信噪比(beam SNR)；测量结果类型字段的值为2，表示感知测量结果的类型为仅为信道状态信息中的幅度信息；测量结果类型字段的值为3，表示感知测量结果的类型为仅为信道状态信息中的相位信息；测量结果类型字段的值为4，表示感知测量结果的类型为仅为信号到达角度信息；测量结果类型字段的值为5，表示感知测量结果的类型为仅为信号出发角度信息；测量结果类型字段的值为6，表示感知测量结果的类型为仅为CSI和信号到达角度信息；测量结果类型字段的值为7，表示感知测量结果的类型为仅为CSI和信号出发角度信息；测量结果类型字段的值为8，表示感知测量结果的类型为仅为表示多普勒信息。可选地，测量结果类型字段9～255范围内的取值保留。
其中，测量结果类型字段所述数值仅是一个示例性介绍，其也可以设置为其它值，只要保证每一种感知测量结果的类型对应的值与其它感知测量结果的类型的值不同即可。例如，测量结果类型字段的值2可以表示信道状态信息；测量结果类型字段的值1可以表示波束信噪比；再例如，测量结果类型字段的值8可以表示信道状态信息；测量结果类型字段的值15可以表示波束信噪比等等。
(7)感知测量的测量频次
在一些实施例中，代理请求帧中可以指示感知测量的测量频次，即指示多长时间进行一次感知测量。可选地，一次感知测量即为一个感知测量实例。
其中，测量频次可以是固定数值，也可以是按需设定的。可选地，测量频次的具体数值可以由相关人员进行设定，也可以由代理发起设备根据需求自动确定，本申请实施例对此不作具体限定。
在一些实施例中，在对感知测量结果的精度要求较高的情况下，测量频次可以设置得较高；在对感知测量结果的精度要求较低的情况下，测量频次可以设置得较低。
在一些实施例中，如图11所示，通过测量频次(Measurement Periodicity)字段指示要求的感知测量的测量频次。在一些实施例中，测量频次字段的值为1，表示感知测量的测量频次为1赫兹(即每秒1次)；测量频次字段的值为2，表示感知测量的测量频次为2赫兹(即每秒2次)；测量频次字段的值为100，表示感知测量的测量频次为100赫兹(即每秒100次)等等，以此类推。
(8)代理响应设备上报感知测量结果的频次
在一些实施例中，代理发起设备可以通过代理请求帧，指示/请求代理响应设备上报感知测量结果的频次，即告知代理响应设备每执行多少次感知测量，代理发起设备就会请求一次感知测量结果，或者代理响应设备主动上报一次感知测量结果。这样，代理响应设备就可以按照代理发起设备指示/请求的频次分配和释放合适的缓存资源。
在一些实施例中，如图11所示，通过上报频次(Report Periodicity)字段指示向代理响应设备请求上报感知测量结果的频次。在一些实施例中，上报频次字段的值为1，表示每1个感知测量实例请求一次感知测量结果；上报频次字段的值为2，表示每2个感知测量实例请求一次感知测量结果；上报频次字段的值为3，表示每3个感知测量实例请求一次感知测量结果，以此类推。
在一些实施例中，对于手势识别或者心跳检测，感知测量实例之间的时间间隔比较小，代理发起设备可能无法保证在每个感知测量实例完成后都能竞争到传输机会来请求代理响应设备发送感知测量结果，这样就要求代理响应设备能够对感知测量结果进行缓存。单个感知测量结果的大小可能是几百字节到几万字节，但是缓存的容量是有限的，所以代理发起设备需要及时获取代理响应设备所缓存的数据；并且，为了及时地产生最终的感知结果，代理发起设备也需要及时获取到感知测量结果，因此可以通过代理请求帧指示向代理响应设备请求上报感知测量结果的频次，从而在使得感知测量结果上报较为顺利的前提下，保证上报的感知测量结果的时效性。
(9)感知测量的测量持续时长
在一些实施例中，代理请求帧可以指示感知测量开始后的持续测量时长，即指示感知测量开始后多长时间结束感知测量。
在一些实施例中，如图11所示，通过测量时长(Measurement Duration)字段：指示要求的感知测量的测量持续的时长，即多久之后结束相应的感知过程。在一些实施例中，时长单位为分钟，测量时长字段的值为1，表示感知测量的测量持续时长为1分钟；测量时长字段的值为2，表示感知测量的测量持续时长为2分钟，依此类推。在另一些实施例中，时长单位为分钟，测量时长字段的值为1，表示感知测量的测量持续时长为1分钟；测量时长字段的值为2，表示感知测量的测量持续时长为2分钟；测量时长字段的值为3，表示感知测量的测量持续时长为4分钟；测量时长字段的值为4，表示感知测量的测量持续时长为8分钟；测量时长字段的值为5，表示感知测量的测量持续时长为16分钟等等，本申请实施例对此不 作具体限定。
(10)参与感知测量的感知参与设备的最小数量
在一些实施例中，感知参与设备越多，感知测量结果越精确。因而，代理发起设备可以根据对感知测量结果的精度要求，通过代理请求帧指示参与感知测量的感知参与设备的最小数量，从而保证感知测量结果的精确性。
在一些实施例中，如图11所示，通过最小感知响应设备数量(Min Responder Number)字段，指示参与感知测量的感知参与设备的最小数量。
(11)指定参与感知测量的感知参与设备的设备信息
在一些实施例中，感知参与设备的设备信息能够影响感知测量结果的准确性以及感知测量的效率。因而，代理请求帧可以指示部分或全部感知参与设备的设备信息。
可选地，设备信息包括：MAC地址、感知参与设备在感知测量中的角色、感知过程中是否使用受保护的管理帧等。在一些实施例中，设备信息还可以包括设备型号、天线数量等。
在一些实施例中，如图11所示，通过感知响应设备列表(Required Responder List)字段：指示指定的感知参与设备的信息。
在一些实施例中，如图11所示，代理请求帧还包括以下字段：
感知需求信息(Sensing Requirement)字段：指示对请求代理建立的测量设置的要求。
控制域(Control)字段：指示后续一个或多个字段(如测量频次字段、上报频次字段、测量时长字段、最小感知响应设备数量字段、感知响应设备列表等)是否存在。
测量频次是否存在(Measurement Periodicity Present)指示位：指示后面的测量频次字段是否存在。在一些实施例中，测量频次是否存在指示位的值若为1，表示后面的测量频次字段存在；测量频次是否存在指示位的值若为0，表示后面的测量频次字段不存在。在另一些实施例中，测量频次是否存在指示位的值若为0，表示后面的测量频次字段存在；测量频次是否存在指示位的值若为1，表示后面的测量频次字段不存在。
上报频次是否存在(Report Periodicity Present)指示位：指示后面的上报频次字段是否存在。在一些实施例中，上报频次是否存在指示位的值若为1，表示后面的上报频次字段存在；上报频次是否存在指示位的值若为0，表示后面的上报频次字段不存在。在另一些实施例中，上报频次是否存在指示位的值若为0，表示后面的上报频次字段存在；上报频次是否存在指示位的值若为1，表示后面的上报频次字段不存在。
测量时长是否存在(Measurement Duration Present)指示位：指示后面的测量时长字段是否存在。在一些实施例中，测量时长是否存在指示位的值若为1，表示后面的测量时长字段存在；测量时长是否存在指示位的值若为0，表示后面的测量时长字段不存在。在另一些实施例中，测量时长是否存在指示位的值若为0，表示后面的测量时长字段存在；测量时长是否存在指示位的值若为1，表示后面的测量时长字段不存在。
最小感知响应设备数量是否存在(Min Responder Number Present)指示位：指示后面的最小感知响应设备数量字段是否存在。在一些实施例中，最小感知响应设备数量是否存在指示位的值若为1，表示后面的最小感知响应设备数量字段存在；最小感知响应设备数量是否存在指示位的值若为0，表示后面的最小感知响应设备数量字段不存在。在另一些实施例中，最小感知响应设备数量是否存在指示位的值若为0，表示后面的最小感知响应设备数量字段存在；最小感知响应设备数量是否存在指示位的值若为1，表示后面的最小感知响应设备数量字段不存在。
感知响应设备列表是否存在(Required Responder List Present)指示位：指示后面的感知响应设备列表字段是否存在。在一些实施例中，感知响应设备列表是否存在指示位的值若为1，表示后面的感知响应设备列表字段存在；感知响应设备列表是否存在指示位的值若为0，表示后面的感知响应设备列表字段不存在。在另一些实施例中，感知响应设备列表是否存在指示位的值若为0，表示后面的感知响应设备列表字段存在；感知响应设备列表是否存在指示位的值若为1，表示后面的感知响应设备列表字段不存在。
在一些实施例中，代理响应帧(SBP response frame)通过字段(如字段的值)携带信息。
在一些实施例中，如图12所示，代理响应帧是一种行动帧或无确认行动帧。其中，行动类别字段的值为4表示该帧为公共行动帧，公共行动子类字段的值为54(公共行动子类字段的取值可以为51～255范围内的任意数值)表示该帧为代理响应帧。
在另一些实施例中，受保护的代理响应帧是一种行动帧或无确认行动帧，行动类别为9表示该帧为受保护的双重公共行动帧类型，公共行动子类值为34(公共行动子类字段的取值可以为33～255范围内的任意数值)表示该帧为受保护的代理响应帧。
在一些实施例中，代理响应帧携带有如下信息中的至少一种：感知测量的测量设置标识(mesurement  setup ID)；感知测量的测量开始时间。
在一些实施例中，代理响应帧中包括测量设置标识字段，用于指示将要建立的感知测量的测量设置标识。
在一些实施例中，代理响应帧中包括测量开始时间(Measurement Start Time)字段，用于指示感知测量的测量开始时间，即第一个感知测量实例的开始时间。在一些实施例中，代理发起设备不参与感知测量，无法直接获取感知测量实例的开始时间，也不能按指定的频次来请求上报感知测量结果。因此代理响应设备可以在代理响应帧中指示测量开始时间。
在一些实施例中，测量开始时间可以设置为目标时间的部分TSF(partial TSF，部分定时同步功能)值，或目标时间与当前时间的偏移值。其中TSF可以表示时间同步功能(timing synchronization function)，部分TSF可以表示同步时间值的截断数据。例如从TSF定时器的64比特中，去除最高有效的38比特和最低有效的10比特。
在一些实施例中，代理响应帧中还包括状态码(Status Code)字段，用于表示感知代理请求是否成功。可选地，状态码字段若为0，指示代理发起设备的感知代理请求成功，即代理响应设备接受代理发起设备的感知代理请求；状态码字段若为1，指示代理发起设备的感知代理请求失败，即代理响应设备拒绝感知代理请求且无原因；状态码字段若为113，指示因无足够数量的感知参与设备而拒绝感知代理请求(可以用113～65535范围内的任一数值表示因无足够数量的感知参与设备而拒绝感知代理请求)。其中，本字段所述数值仅是一个示例性介绍，其也可以设置为其它值，只要保证每一种状态码字段的值与其它状态码字段的值不同即可。
可选地，当状态码字段指示代理发起设备的感知代理请求成功时，测量设置标识字段存在；否则测量设置标识字段不存在。
可选地，当状态码字段指示成功时，测量开始时间字段存在；否则测量开始时间字段不存在。
在一些实施例中，代理响应帧是代理响应设备在发起感知测量的测量设置之前发送的。
在一些实施例中，如图13所示，代理发起设备请求代理响应设备建立代理的感知测量(如WLAN感知)，代理响应设备可以在发起感知测量设置之前给代理发起设备发送代理响应帧。代理响应设备可以与关联的站点(associated STA)建立感知测量设置。可选地，通过关联标识符标识与代理响应设备建立关联后的设备。
在一些实施例中，如图14所示，代理发起设备请求代理响应设备建立代理的感知测量(如WLAN感知)，代理响应设备可以在发起感知测量设置之前给代理发起设备发送代理响应帧。代理响应设备可以与关联的站点和/或未关联的站点(unassociated STA)建立感知测量设置。例如，如图14所示，代理响应设备2为未关联的站点，在代理响应设备与之建立感知测量设置之前，代理响应设备2需要先发送感知测量设置查询帧(MS Query)给代理响应设备。
其中，关联的站点是指与代理响应设备之间存在通信连接(如网络连接)的站点，未关联的站点是指与代理响应设备之间没有建立通信连接的站点。例如，若代理响应设备为无线路由器，则其关联的站点可以是与无线路由器之间存在网络连接的智能电视、感知测量传感器、智能手机等设备，该无线路由器的关联站点还可以是与该无线路由器存在通信连接的其他无线路由器。
在一些实施例中，代理响应帧是代理响应设备在完成感知测量的测量设置之后发送的。
在一些实施例中，如图15所示，代理发起设备请求代理响应设备建立代理的感知测量(如WLAN感知)，代理响应设备可以在完成感知测量设置之后给代理发起设备发送代理响应帧。
在一些实施例中，代理响应帧是代理响应设备在发起感知测量的测量设置之后发送的。
在一些实施例中，如图16所示，代理发起设备请求代理响应设备建立代理的感知测量(如WLAN感知)，代理响应设备可以在发起感知测量设置之后给代理发起设备发送代理响应帧。
在一些实施例中，代理请求帧的发送时刻和代理响应帧的接收时刻之间的时长小于或等于第一时间间隔。
可选地，第一时间间隔为超时时长(timeout)；可选地，超时时长是预定义的超时时长(Predefined timeout)。如图13至16所示，代理请求帧的发送时刻和代理响应帧的接收时刻之间的时长小于或等于超时时长T1。
在一些实施例中，如图13至16所示，对于一个感知测量设置请求以及与这一个感知测量设置请求对应的感知测量设置响应，该感知测量设置请求的发送时刻和感知测量设置响应的接收时刻之间的时长也是小于或等于超时时长T1。也即，感知测量设置请求的和感知测量设置响应对应的超时时长，与代理请求帧和代理响应帧对应的超时时长相同。
可选地，如图14所示，感知测量设置请求的和感知测量设置响应对应的超时时长、感知测量设备查 询帧和感知测量设置请求对应的超时时长、代理请求帧和代理响应帧对应的超时时长相同。
在一些实施例中，代理发起设备向代理响应设备发送感知能力信息，和/或，代理发起设备接收代理响应设备发送的感知能力信息。
在能力交换(即能力交互)阶段，设备可以在感知能力信息(如通过图17所示的扩展的能力元素(Extended Capabilities element))中指示设备自身的感知能力(essential sensing capabilities)。
在一些实施例中，如图17所示，感知能力信息携带有如下信息中的至少一种：支持代理的感知测量；支持的同时运行的测量设置的最大数量。其中，对于non-AP STA，支持代理的感知测量的含义为支持该设备作为代理发起设备；对于AP STA。支持代理的感知测量的含义为支持作为代理响应设备。
可选地，如图17所示，感知能力信息还可以携带有信息用于指示设备支持代理的感知测量(如WLAN感知)。例如，通过将感知能力信息中“是否支持代理的感知测量”的字段的值设置为第一取值(第一取值表示支持代理的感知测量)，指示代理发起设备或代理请求设备支持代理的感知测量。
在一些实施例中，在能力交换(即能力交互)阶段，设备在感知能力元素中指示自身具体的感知能力(detailed sensing capabilities)。如图18所示，感知能力元素可以指示设备是否支持感知信号发送设备的角色、和/或是否支持感知信号接收设备的角色、和/或是否支持感知发起设备的角色、和/或是否支持基于触发帧的感知响应设备的角色、和/或是否支持非基于触发帧的感知响应设备的角色、和/或是否支持基于阈值的感知测量、和/或是否支持上报测量结果、和/或是否支持作为感知发起设备接收合并的感知测量结果、和/或是否支持作为感知信号接收设备上报合并的感知测量结果、和/或可以同时运行的测量设置的最大数量。
不同的站点可以同时运行的测量设置的最大数量可能不同。例如，AP可能支持同时运行4个不同的测量设置，STA1可能仅支持2个，那么AP跟STA1之间仅能建立2个同时运行的不同的测量设置。又例如AP可能支持同时运行8个不同的测量设置，STA2可能仅支持1个，那么AP跟STA1之间仅能建立1个运行中的测量设置。
在一些实施例中，由于设备自身能力限制，或用户设置限制，或存储资源限制，或电能限制等原因，站点可以同时运行的测量设置的数量存在一定限制。可选地，AP和/或STA2在已有运行中的测量设置的数量达到该限制数量的情况下，不应当尝试跟对方建立新的不同的测量设置。例如AP不应当在测量实例中的轮询触发帧(TF Poll)中指示将要与STA2建立新的不同的测量设置，STA2也不应当发送测量设置查询帧(Measurement Setup Query)和/或测量设置请求帧(Measurement Setup Request)来尝试与AP建立新的不同的测量设置。
在一些实施例中，扩展的能力元素可以携带于信标帧(Beacon)、和/或探测请求帧(Probe Request)、和/或探测响应帧(Probe Response)、和/或关联请求帧(Association Request)、和/或关联响应帧(Association Response)、和/或重关联请求帧(Reassociation Request)、和/或重关联响应帧(Reassociation Response)中。
在一些实施例中，感知能力元素可以携带于信标帧、和/或探测请求帧、和/或探测响应帧、和/或关联请求帧、和/或关联响应帧、和/或重关联请求帧、和/或重关联响应帧、和/或测量设置查询帧中。
上文仅从代理发起设备和代理响应设备交互的角度，对本申请技术方案进行了介绍说明。上述有关代理发起设备执行的步骤，可单独实现为代理发起设备侧的感知测量方法；上述有关代理响应设备执行的步骤，可单独实现为代理响应设备侧的感知测量方法。
在一些实施例中，如图19所示，本申请实施例还提供了一种能力交互方法，该方法包括如下步骤(1901)：
步骤1901，向第二通信设备发送感知能力信息，感知能力信息携带有如下信息中的至少一种：是否支持代理的感知测量；支持的同时运行的测量设置的最大数量。
可选地，如图17所示，第一通信设备通过其感知能力信息中“是否支持代理的感知测量”字段，指示第一通信设备是否支持代理的感知测量。例如，若“是否支持代理的感知测量”字段的值为1，表示第一通信设备支持代理的感知测量；若“是否支持代理的感知测量”字段的值为0，表示第一通信设备不支持代理的感知测量。
其中，对于non-AP STA，是否支持代理的感知测量的含义为是否支持该设备作为代理发起设备；对于AP STA。是否支持代理的感知测量的含义为是否支持作为代理响应设备。
