为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
WLAN Sensing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。也即，WLAN Sensing通过无线信号来对周围环境进行测量和感知，从而可以完成室内是否有人入侵、移动、跌倒等的检测，姿势识别以及空间三维图像建立等诸多功能。
为便于理解本申请实施例的技术方案，以下对本申请相关WLAN感知进行说明。
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)，发起感知会话(sensing session)并想要获知感知结果的设备；
感知响应设备(Sensing Responder)，参与sensing session的非Sensing Initiator的设备；
感知发送设备(Sensing Transmitter)，发起感知测量信号(sensing illumination signal)的设备；
感知接收设备(Sensing Receiver)，接收感知测量信号(sensing illumination signal)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)，包括感知会话发起设备，感知信号发送设备和感知信号接收设备。
WLAN终端在一个感知会话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。
在一些实施例中，可以具有多种感知类型(Sensing Type)。例如，基于信道状态信息(Channel State Information，CSI)的感知类型，即CSI-based Sensing，该感知类型是通过处理接收到的感知测量信号的CSI获得sensing测量结果。又例如，基于反射信号的感知类型，即Radar-based Sensing，该感知类型是通过处理接收到的感知测量信号的反射信号获得sensing测量结果。
WLAN感知会话包括以下一个或多个阶段：会话建立、感知测量、感知上报、会话终止。
会话建立阶段：建立感知会话，确定感知会话参与者及其角色(包括感知发送设备和感知接收设备)，决定感知会话相关的操作参数，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接收设备。
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发起设备上报测量结果。
会话终止阶段：终端停止测量，终止感知会话。
在感知会话建立时，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)。
感知测量结果的数据量通常比较大，例如一次测量的信道状态信息(Channel State Information，CSI)数据可能达到4K～40K比特，为了降低上报感知测量结果导致的网络负载，可以设置测量阈值，当本次感知测量结果与上次的感知测量结果的变化量小于该测量阈值时，感知接收设备上报感知测量结果，否则不上报感知测量结果。
感知发起设备可以设置多组测量参数，一组测量参数(用测量设置标识(Measurment Setup ID)来标识，可以等价于突发信号组(Burst Group))可以应用于多次测量(用测量实例标识(Measurement Instance ID)来标识，可以等价于突发信号(Burst))。
感知测量是WLAN感知的一个核心步骤，然而，具体如何配置针对感知测量的测量信息是一项急需解决的问题。
WLAN Sensing采用成对(Pairwise)的方式进行，并且包含以下两个标识(ID)，用于区分建立(Setup)和测量(measurement)实例：
1)测量建立标识(Measurement Setup ID)，测量建立标识可用于识别感知测量实例中使用的属性，测量建立在协商阶段分别提供给每个响应设备，测量建立标识在共享相同测量实例的响应程序中设置为相同的值。
2)测量实例标识(Measurement Instance ID)，测量实例标识根据测量建立标识唯一标识感知测量实例，测量实例标识用于识别属于同一感知测量实例的帧。
值得注意的是，如图2所示，在一个测量建立标识(Measurement Setup ID)下，可以有不同的测量实例(Measurement Instance)，这些Measurement Instance可以采用不同的测量方式，例如参与测量的设备不同，测量采用的参数也可以不同，等等。
如图2所示，感知发起设备可以设置多组测量参数，一组测量参数(用Measurment Setup ID来标识，可以等价于突发信号组(Burst Group))可以应用于多次测量(用Measurement Instance ID来标识，可以等价于突发信号(Burst))。
为便于更好的理解本申请实施例，对本申请相关的非基于触发的(non-TB)测距(Ranging)进行说明。
non-TB Ranging是在一对设备(ISTA和RSTA)之间进行测距。在设置好的测量窗口，ISTA通过测距(Ranging)无数据的物理层协议数据单元宣告(null data physical layer protocol data unit announcement，NDPA)+ISTA至RSTA(I2R)无数据的物理层协议数据单元(null data physical layer protocol data unit，NDP)发起测量，然后RSTA发送RSTA至ISTA(R2I)NDP进行测量。根据ISTA和RSTA的设置，测量报告阶段(Measurement Reporting phase)可以是图3的单向R2I位置测量报告(Location Measurement Report，LMR)，也可以是图4双向的LMR(R2I LMR+I2R LMR)。
现阶段，WLAN Sensing机制只提出了成对进行感知建立(Sensing Setup)，感知测量(Sensing Measurement)以及感知上报(Sensing Reporting)，以上各个阶段具体如何实现及帧结构如何设计，是一个亟待解决的问题。此外，上述non-TB Ranging只适用于WLAN设备之间进行测距，不支持802.11bf标准中定义的WLAN Sensing，因此有必要以802.11az non-TB Ranging协议为基础设计适用于802.11bf的non-TB Sensing协议和帧结构。
基于上述问题，本申请提出了一种感知测量的方案，对于单向发送NDP，可以通过NDPA指示发送NDP的设备，对于双向发送NDP，能够通过NDPA指示发送NDP的顺序，从而，可以实现non-TB感知测量，在符合成对(Pairwise)感知测量的前提下，提升了感知测量的灵活性。
以下通过具体实施例详述本申请的技术方案。
图5是根据本申请实施例的无线通信的方法200的示意性流程图，如图5所示，该无线通信的方法200可以包括如下内容中的至少部分内容：
S210，第一设备向第二设备发送NDPA；其中，该NDPA包括第一信息，该第一信息用于指示以下之一：单向发送NDP或双向发送NDP；发送该NDPA的设备先发送NDP或接收该NDPA的设备先发送NDP；单向发送NDP，且发送该NDPA的设备发送NDP，接收该NDPA的设备不发送NDP；双向发送NDP，且发送该NDPA的设备先发送NDP，接收该NDPA的设备后发送NDP；双向发送NDP，且接收该NDPA的设备先发送NDP，发送该NDPA的设备后发送NDP；单向发送NDP，且发送该NDPA的设备不发送NDP，接收该NDPA的设备发送NDP；
S220，该第二设备接收该第一设备发送的该NDPA。
在本申请实施例中，对于单向发送NDP，可以通过NDPA指示发送NDP的设备，对于双向发送NDP，能够通过NDPA指示发送NDP的顺序，从而，可以实现non-TB感知测量，在符合成对(Pairwise)感知测量的前提下，提升了感知测量的灵活性。
在一些实施例中，该第一设备为感知发送设备(Sensing Transmitter)，且该第二设备为感知接收设备(Sensing Receiver)；或者，该第一设备为感知接收设备(Sensing Receiver)，且该第二设备为感知发送设备(Sensing Transmitter)。
在一些实施例中，该第一设备也可以为感知发起设备或感知响应设备，
在一些实施例中，该第一信息可以占用1比特，设置为0表示单向发送NDP，设置为1表示双向发送NDP。或者，设置为1表示单向发送NDP，设置为0表示双向发送NDP。本申请对此并不限定。
在一些实施例中，在双向发送NDP的情况下，该第一信息可以占用1比特，设置为0表示发送该NDPA的设备先发送NDP，设置为1表示接收该NDPA的设备先发送NDP。或者，设置为1表示发送该NDPA的设备先发送NDP，设置为0表示接收该NDPA的设备先发送NDP。本申请对此并不限定。
在一些实施例中，该第一信息可以占用2比特，设置为00表示单向发送NDP，且发送该NDPA的设备发送NDP，接收该NDPA的设备不发送NDP；设置为01表示双向发送NDP，且发送该NDPA的设备先发送NDP，接收该NDPA的设备后发送NDP；设置为10表示双向发送NDP，且接收该NDPA的设备先发送NDP，发送该NDPA的设备后发送NDP；设置为11表示单向发送NDP，且发送该NDPA的设备不发送NDP，接收该NDPA的设备发送NDP。当然，该第一信息也可以占用更多的比特，以及通过设置于此不同的取值指示上述信息，本申请对此并不限定。
在一些实施例中，该第一信息为承载该NDPA的帧中的NDP顺序(NDP Order)字段。
在一些实施例中，承载该NDPA的帧包括通用信息字段和站点信息字段，其中，该通用信息字段包括第一字段和该NDP顺序字段，该第一字段用于指示本次测量为非基于触发的感知测量，该站点信息字段包括第二字段和第三字段，该第二字段用于指示下行测量的NDP的空时流(spatial-time stream)数量，该第三字段用于指示下行测量的NDP的长训练域(Long Training Field，LTF)符号的重复数量。
在一些实施例中，该第一字段为基于触发/非基于触发的(TB/non-TB)字段，该TB/non-TB字段用于指示本次测量为TB或non-TB类型，如该TB/non-TB字段占用1比特，取值为0指示本次测量为TB类型，取值为1指示本次测量为non-TB类型。
在一些实施例中，该第二字段为下行NDP空时流(DL N_STS)字段，该DL N_STS字段占用4比特，用于指示下行测量的NDP的空时流(spatial-time stream)数量。
在一些实施例中，该第三字段为下行重复(DL Rep)字段，该DL Rep字段占用4比特，用于指示下行测量的NDP的LTF符号的重复数量。
在一些实施例中，承载该NDPA的帧可以是NDPA帧或感知宣告帧(Sensing Announcement)。当然，承载该NDPA的帧也可以是其他帧，本申请对此并不限定。
在一些实施例中，在承载NDPA的帧为感知宣告帧的情况下，如图6所示，定义了感知控制帧:一种新的控制帧，帧类型(Type)为1表示该帧为控制帧，帧子类型(Subtype)值为5表示该帧为扩展控制帧，控制帧扩展(Control Frame Extension)值为11(可以为11～15中任一值)表示该帧为感知控制帧，感知子类型(Sensing Subtype)值为1(可以为0～15中任一值)表示该帧为感知宣告帧(Sensing Announcement)。
如图6所示，感知宣告帧中的通用信息字段包括TB/non-TB字段和NDP顺序字段。
TB/non-TB字段用于指示本次测量为TB或non-TB类型。可选地，可由是否有触发感知轮询(TF SENS Poll)来判定。
NDP顺序字段占用2比特，具体的，NDP顺序＝00:单向发送NDP，发送NDPA的设备发送NDP，接收NDPA的设备不发送NDP；NDP顺序＝01:双向发送NDP，发送NDPA的设备先发送NDP，接收NDPA的设备后发送NDP；NDP顺序＝10:双向发送NDP，接收NDPA的设备先发送NDP，发送NDPA的设备后发送NDP；或者NDP顺序＝10为预留值(reserved)；NDP顺序＝11:单向发送NDP，发送NDPA的设备不发送NDP，接收NDPA的设备发送NDP。
例如，在感知建立(Sensing Setup)时如果设定一个设备只能是感知发送设备(Sensing Transmitter)，另一个设备只能是感知接收设备(Sensing Receiver)，那么只能单向发送NDP，此时NDP顺序字段设为00。
如图6所示，感知宣告帧中的站点信息字段包括DL N_STS字段和DL Rep字段，其中，DL N_STS字段占用4比特，用于指示下行测量的NDP的空时流(spatial-time stream)数量；DL Rep字段占用4比特，用于指示下行测量的NDP的LTF符号的重复数量。
在一些实施例中，该NDPA对应的测量实例中执行的感知测量包括以下至少之一：上行感知测量，下行感知测量，双向感知测量。
在一些实施例中，如果在感知建立(Sensing Setup)阶段设置了设备既支持发送(TX)又支持接收(RX)，那么在不同的测量实例中，可以通过NDPA帧的NDP顺序字段灵活指示某个测量实例仅做上行感知测量或下行感知测量或双向感知测量等。
在一些实施例中，在感知测量阶段，只进行单向感知测量(Sensing Measurement)，感知发送设备(Sensing Transmitter)发送NDPA+NDP。
在一些实施例中，在感知测量阶段，进行双向感知测量(Sensing Measurement)，先获得信道的设备先发送NDPA+NDP。
在一些实施例中，在感知测量阶段，进行双向感知测量(Sensing Measurement)，强制AP先发送NDPA+NDP。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持双向感知测量的情况下，由AP发送NDPA。也即，在该NDPA对应的测量实例在感知建立阶段设置为支持双向感知测量的情况下，总是由AP发送NDPA。
在一些实施例中，该NDPA对应的测量实例在感知建立阶段设置为：AP发送NDPA，且Non-AP STA等待AP发送的NDPA。也即，在感知建立阶段设置强制规则：在感知建立阶段设置了双向感知测量的测量实例中，必须由AP发送NDPA帧，Non-AP STA需要等待AP发送的NDPA帧，无需信令指示。
具体例如，如图7所示，进入感知测量阶段(Sensing Measurement phase)时，Non-AP STA不可以首先发送NDPA帧开启感知测量(Sensing Measurement)，而是要等待AP发送NDPA帧来开启感知测量(Sensing Measurement)。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持双向感知测量的情况下，由先获取信道使用权的设备发送NDPA。例如，先获得信道使用权(Contention based access)的设备先发送NDPA。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持双向感知测量的情况下，也可以默认发送NDPA的设备先发送NDP，接收NDPA的设备后发送NDP。
具体例如，如图8所示，如果AP先获得信道使用权，那么由AP发送NDPA，且AP先发送NDP进行感知测量(Sensing Measurement)，然后Non-AP STA发送NDP进行感知测量(Sensing Measurement)。
具体又例如，如图9所示，如果Non-AP STA先获得信道使用权，那么由Non-AP STA发送NDPA，且Non-AP STA先发送NDP进行感知测量(Sensing Measurement)，然后AP发送NDP进行感知测量(Sensing Measurement)。
需要说明的是，在上述图8和图9中，默认发送NDPA帧的设备在短帧间间隔(Short Interframe Space，SIFS)时间之后直接发送NDP进行感知测量，然后另一个设备在SIFS时间之后再发NDP进行反向的感知测量。但NDP的发送顺序可以不限定为发送NDPA帧的设备先发送NDP，还可以通过NDPA帧中的NDP顺序字段来指示后面两个NDP帧的发送顺序。
例如，在上述图8和图9中，该第一信息可以指示：双向发送NDP，且发送NDPA的设备先发送NDP，接收NDPA的设备后发送NDP。
具体例如，如图10所示，如果AP先获得信道使用权，那么由AP发送NDPA，该第一信息可以指示：双向发送NDP，且接收NDPA的设备先发送NDP，发送NDPA的设备后发送NDP，也即，Non-AP STA先发送NDP进行感知测量(Sensing Measurement)，然后AP发送NDP进行感知测量(Sensing Measurement)。
具体又例如，如图11所示，如果Non-AP STA先获得信道使用权，那么由Non-AP STA发送NDPA，该第一信息可以指示：双向发送NDP，且接收NDPA的设备先发送NDP，发送NDPA的设备后发送NDP，也即，且AP先发送NDP进行感知测量(Sensing Measurement)，然后Non-AP STA发送NDP进行感知测量(Sensing Measurement)。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持双向感知测量的情况下，该NDPA对应的测量实例在感知建立阶段配置有第二信息，其中，该第二信息用于指示由AP发送NDPA，或者，该第二信息用于指示由先获取信道使用权的设备发送NDPA。
在一些实施例中，该第二信息为第一帧中的NDPA发送者(NDPA Sender)字段，其中，该第一帧为感知建立请求帧(Sensing Setup Request frame)或感知建立响应帧(Sensing Setup Response frame)。
在一些实施例中，该第一帧包括动作域，该动作域包括感知响应设备信息字段，该感知响应设备信息字段包括该NDPA发送者(NDPA Sender)字段。
具体例如，当NDPA发送者＝0，先获得信道使用权的设备(无论AP还是STA)先发送NDPA；当NDPA发送者＝1，则采用由AP发送NDPA帧，Non-AP STA需要等待AP发送的NDPA帧。或者，当NDPA发送者＝1，先获得信道使用权的设备(无论AP还是STA)先发送NDPA；当NDPA发送者＝0，则采用由AP发送NDPA帧，Non-AP STA需要等待AP发送的NDPA帧。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持双向感知测量的情况下，AP在感知建立阶段设置为允许作为感知发送设备(Sensing Transmitter)和感知接收设备(Sensing Receiver)，Non-AP STA在感知建立阶段设置为允许作为感知发送设备(Sensing Transmitter)和感知接收设备(Sensing Receiver)。也即，如果某个测量实例在感知建立阶段的设置为：AP既可以是感知发送设备(Sensing Transmitter)又可以是感知接收设备(Sensing Receiver)，那么同样Non-AP STA也既可以是感知发送设备(Sensing Transmitter)又可以是感知接收设备(Sensing Receiver)。
在一些实施例中，该第一设备根据该第一信息向该第二设备发送NDP，和/或，该第一设备根据该第一信息接收该第二设备发送的NDP。
在一些实施例中，在感知上报阶段，只进行了单向感知测量(Sensing Measurement)，感知发起设备(Sensing Initiator)是感知发送设备(Sensing Transmitter)，感知接收设备(Sensing Receiver)需要发送感知测量报告(Sensing Report)给感知发送设备(Sensing Transmitter)。
在一些实施例中，在感知上报阶段，只进行了单向感知测量(Sensing Measurement)，感知发起设备(Sensing Initiator)是感知接收设备(Sensing Receiver)，感知接收设备(Sensing Receiver)不需要发送感知测量报告(Sensing Report)。
在一些实施例中，在感知上报阶段，只进行了单向感知测量(Sensing Measurement)，感知发起设备(Sensing Initiator)未参与感知测量(Sensing Measurement)，感知接收设备(Sensing Receiver)是Non-AP STA，那么Non-AP STA需要发送感知测量报告(Sensing Report)给AP，AP再将感知测量报告(Sensing Report)发给感知发起设备(Sensing Initiator)。
在一些实施例中，在感知上报阶段，只进行了单向感知测量(Sensing Measurement)，感知发起设备(Sensing Initiator)未参与感知测量(Sensing Measurement)，感知接收设备(Sensing Receiver)是AP，那么AP直接将感知测量报告(Sensing Report)发给感知发起设备(Sensing Initiator)。
在一些实施例中，在感知上报阶段，进行了双向感知测量(Sensing Measurement)，感知发起设备(Sensing Initiator)是AP且参与了感知测量(Sensing Measurement)，那么Non-AP STA需要发送感知测量报告(Sensing Report)给AP。
在一些实施例中，在感知上报阶段，进行了双向感知测量(Sensing Measurement)，感知发起设备(Sensing Initiator)是Non-AP STA且参与了感知测量(Sensing Measurement)，那么AP需要发送感知测量报告(Sensing Report)给STA。
在一些实施例中，在感知上报阶段，进行了双向感知测量(Sensing Measurement)，感知发起设备(Sensing Initiator)未参与感知测量(Sensing Measurement)，那么Non-AP STA需要发送感知测量报告(Sensing Report)给AP，AP再将感知测量报告(Sensing Report)发给感知发起设备(Sensing Initiator)。
在一些实施例中，感知测量结果要发给发送感知建立请求(Sensing Setup Request)的设备：
如果Sensing Initiator参与Sensing Measurement，那么Sensing Initiator发送Sensing Setup Request，感知测量结果会反馈给Sensing Initiator；
如果Sensing Initiator不参与Sensing Measurement，那么由AP代理发送Sensing Setup Request，感知测量结果会发送给AP然后由反馈给Sensing Initiator。
在一些实施例中，在感知发起设备未参与感知测量的情况下，该感知发起设备通过AP获取感知测量结果。例如，该感知发起设备(Sensing Initiator)为Non-AP STA，且该感知发起设备触发建立了AP与至少一个Non-AP STA之间的感知会话。
在一些实施例中，在感知发起设备未参与感知测量的情况下，在该第一设备为AP，且该第二设备为Non-AP STA的情况下，该第一设备接收该第二设备发送的感知测量结果。
在一些实施例中，在感知发起设备未参与感知测量，以及在该第一设备为AP，且该第二设备为Non-AP STA的情况下，该第一设备接收该感知发起设备发送的感知发起请求(Sensing Initiating Request)；该第一设备向至少一个Non-AP STA发送感知建立请求，其中，该至少一个Non-AP STA 包括该第二设备；该第一设备接收该至少一个Non-AP STA发送的感知建立响应；该第一设备向该感知发起设备发送感知发起响应(Sensing Initiating Response)。
在一些实施例中，在感知发起设备未参与感知测量的情况下，在该第一设备为Non-AP STA，且该第二设备为AP的情况下，该第一设备向该第二设备发送感知测量结果。
在一些实施例中，在感知发起设备未参与感知测量，以及在该第一设备为Non-AP STA，且该第二设备为AP的情况下，该第一设备接收该第二设备发送的感知建立请求；该第一设备向该第二设备发送感知建立响应。
具体例如，如果感知发起设备(Sensing Initiator)未参与感知测量(Sensing Measurement)，那么感知发起设备(Sensing Initiator)是Non-AP STA。如图12和图13所示，首先STA 2需要发送感知测量结果(Sensing Report)给AP，然后AP将感知测量结果(Sensing Report)发送给感知发起设备(STA 1)。
在一些实施例中，在感知发起设备参与了感知测量，且该第一设备为该感知发起设备的情况下，该第一设备接收该第二设备发送的感知测量结果。进一步地，该第一设备不向该第二设备发送感知测量结果。
在一些实施例中，在感知发起设备参与了感知测量，且该第一设备为该感知发起设备的情况下，该第一设备向至少一个Non-AP STA发送感知建立请求，其中，该至少一个Non-AP STA包括该第二设备；以及该第一设备接收该至少一个Non-AP STA发送的感知建立响应。
在一些实施例中，在感知发起设备参与了感知测量，且该第二设备为该感知发起设备的情况下，该第一设备向该第二设备发送感知测量结果。
在一些实施例中，在感知发起设备参与了感知测量，且该第二设备为该感知发起设备的情况下，该第一设备接收该第二设备发送的感知建立请求；以及该第一设备向该第二设备发送感知建立响应。
具体例如，如果感知发起设备(Sensing Initiator)参与了感知测量(Sensing Measurement)，如图14所示，如果AP是Sensing Initiator，那么STA需要发送感知测量结果(Sensing Report)给AP，但AP不需要发送感知测量结果(Sensing Report)给STA。
具体例如，如果感知发起设备(Sensing Initiator)参与了感知测量(Sensing Measurement)，如图15所示，如果STA是Sensing Initiator，那么AP需要发送感知测量结果(Sensing Report)给STA，但STA不需要发送感知测量结果(Sensing Report)给AP。
在一些实施例中，该感知建立请求通过感知建立请求帧发送，其中，该感知建立请求帧包括动作域，该动作域包括感知响应设备信息字段，该感知响应设备信息字段包括NDPA发送者字段，该NDPA发送者字段的取值用于指示由AP发送NDPA，或者，该NDPA发送者字段的取值用于指示由先获取信道使用权的设备发送NDPA。
具体例如，如图16所示，定义了感知动作帧(Sensing Action frame):一种新的动作帧(Action frame)或无确认动作帧(Action No Ack)，动作类别(Category)为4表示该帧为公共动作帧(Public Action frame)，公共动作子类(Public Acton Field)值为46表示该帧为感知动作帧(可以用46～255范围内任意数值来表示该帧为感知动作帧)，感知子类(Sensing Subtype)值为2(可以用0～255范围内任意数值)指示为感知建立请求帧(Sensing Setup Request frame)。

在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持单向感知测量的情况下，由感知发送设备发送NDPA。
具体的，如果仅支持单向的感知测量，意味着在AP与Non-AP STA之中，其中一个仅支持感知发送设备(Sensing Transmitter)，另一个仅支持感知接收设备(Sensing Receiver)。
在一些实施例中，感知发送设备(Sensing Transmitter)获得信道使用权后(Contention based access)，可以直接发送NDPA+NDP进行单向的Sensing Measurement。即默认发送NDPA帧的设备在SIFS时间之后直接发送NDP进行单向的感知测量。
具体例如，如图20所示，如果某个测量实例(Measurement Instance)在感知建立(Sensing Setup)阶段的设置为：AP是感知发送设备(Sensing Transmitter)，Non-AP STA是感知接收设备(Sensing Receiver)，那么AP发送NDPA+NDP进行感知测量(sensing measurement)。
在一些实施例中，感知发送设备(Sensing Transmitter)获得信道使用权后(Contention based access)，感知发送设备可以直接发送NDPA，然后，感知发送设备和/或感知接收设备根据第一信息确定是否发送NDP。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持单向感知测量的情况下，以及在该第一信息指示发送该NDPA的设备发送NDP，且接收该NDPA的设备不发送NDP的情况下，该第一设备向该第二设备发送NDP。
具体又例如，如图21所示，如果某个测量实例(Measurement Instance)在感知建立(Sensing Setup)阶段的设置为：Non-AP STA是感知发送设备(Sensing Transmitter)，AP是感知接收设备(Sensing Receiver)，那么Non-AP STA发送NDPA+NDP进行感知测量(sensing measurement)。
具体例如，如图20所示，如果某个测量实例(Measurement Instance)在感知建立(Sensing Setup)阶段的设置为：AP是感知发送设备(Sensing Transmitter)，Non-AP STA是感知接收设备(Sensing Receiver)，那么AP发送NDPA，以及第一信息指示：单向发送NDP，且发送NDPA的设备发送NDP，接收NDPA的设备不发送NDP，此种情况下，AP发送NDP进行感知测量(sensing measurement)。
具体又例如，如图21所示，如果某个测量实例(Measurement Instance)在感知建立(Sensing Setup)阶段的设置为：Non-AP STA是感知发送设备(Sensing Transmitter)，AP是感知接收设备(Sensing Receiver)，那么Non-AP STA发送NDPA，以及第一信息指示：单向发送NDP，且发送NDPA的设备发送NDP，接收NDPA的设备不发送NDP，此种情况下，Non-AP STA发送NDP进行感知测量(sensing measurement)。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持单向感知测量的情况下，以及在该第一信息指示发送该NDPA的设备不发送NDP，且接收该NDPA的设备发送NDP的情况下，该第一设备接收该第二设备发送的NDP。
具体例如，如图22所示，如果某个测量实例(Measurement Instance)在感知建立(Sensing Setup)阶段的设置为：AP是感知发送设备(Sensing Transmitter)，Non-AP STA是感知接收设备(Sensing Receiver)，那么AP发送NDPA，以及第一信息指示：单向发送NDP，且发送NDPA的设备不发送NDP，接收NDPA的设备发送NDP，此种情况下，Non-AP STA发送NDP进行感知测量(sensing measurement)。
具体又例如，如图23所示，如果某个测量实例(Measurement Instance)在感知建立(Sensing Setup)阶段的设置为：Non-AP STA是感知发送设备(Sensing Transmitter)，AP是感知接收设备(Sensing Receiver)，那么Non-AP STA发送NDPA，以及第一信息指示：单向发送NDP，且发送NDPA的设备不发送NDP，接收NDPA的设备发送NDP，此种情况下，AP发送NDP进行感知测量(sensing measurement)。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持单向感知测量的情况下，以及在该第一设备为该感知发起设备的情况下，该第一设备接收该第二设备发送的感知测量结果。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持单向感知测量的情况下，以及在该第一设备为该感知发起设备的情况下，该第一设备不向该第二设备发送感知测量结果。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持单向感知测量的情况下，以及在该第二设备为该感知发起设备的情况下，该第一设备向该第二设备发送感知测量结果。
具体例如，如图24所示，在感知发起设备(Sensing Initiator)参与了感知测量(Sensing Measurement)的情况下，对于单向感知测量，如果感知发送设备(Sensing Transmitter)(AP or STA)是感知发起设备(Sensing Initiator)，感知接收设备(Sensing Receiver)不需要发感知报告(Sensing Report)给Sensing Initiator，因为Sensing Initiator可通过NDP直接获得感知结果。感知接收设备(Sensing Receiver)(STA or AP)需要发送感知报告(Sensing Report)给感知发送设备(Sensing Transmitter)，感知发送设备(Sensing Transmitter)可通过感知报告(Sensing Report)获得感知结果。
具体例如，如图25所示，在感知发起设备(Sensing Initiator)未参与感知测量(Sensing Measurement)的情况下，对于单向感知测量，感知发起设备(Sensing Initiator)是Non-AP STA(即STA1)，如图25所示，感知接收设备(Sensing Receiver)是Non-AP STA(即STA2)，那么STA2将感知报告(Sensing Report)发送给AP，AP再将感知报告(Sensing Report)转发给Sensing Initiator(即STA1)。
具体又例如，如图26所示，在感知发起设备(Sensing Initiator)未参与感知测量(Sensing Measurement)的情况下，对于单向感知测量，感知发起设备(Sensing Initiator)是Non-AP STA(即STA1)，如图26所示，感知接收设备(Sensing Receiver)是AP，那么AP将感知报告(Sensing Report)直接发送给感知发起设备(Sensing Initiator)(即STA1)。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持单向感知测量的情况下，以及在该第一设备为该感知发起设备的情况下，该第一设备向该第二设备发送感知建立请求；该第一设备接收该第二设备发送的感知建立响应。
在一些实施例中，在该NDPA对应的测量实例在感知建立阶段设置为支持单向感知测量的情况下，以及在该第二设备为该感知发起设备的情况下，该第一设备接收该第二设备发送的感知建立请求；该第一设备向该第二设备发送感知建立响应。
在一些实施例中，如果只有1对设备参与感知测量(Sensing Measurement)，在感知建立阶段(Sensing Setup phase)，1对设备中的一个是感知发起设备(Sensing Initiator)，另一个是感知响应设备(Sensing Responder)。如图27所示，在这种场景下，无论Sensing Initiator和Sensing Responder是AP还是STA，均由Sensing Initiator发送感知建立请求帧(Sensing Setup Request frame)发起感知建立(Sensing Setup)，然后Sensing Responder回复感知建立响应(Sensing Setup Response frame)完成感知建立阶段(Sensing Setup phase)。
在一些实施例中，在感知建立阶段(Sensing Setup phase)，如果有多对设备参与感知测量(Sensing Measurement)，且感知发起设备(Sensing Initiator)能够参与所有的感知测量(Sensing Measurement)或者感知测量实例(Sensing Measurement Instance)，那么意味着该感知发起设备(Sensing Initiator)是AP。如图28所示，在这种场景下，AP(Sensing Initiator)可以与各个STA(Sensing Responder 1～N)分别一对一的进行Sensing Setup，以符合成对(Pairwise)的感知(sensing)规则。
在一些实施例中，在感知建立阶段(Sensing Setup phase)，如果有多对设备参与感知测量(Sensing Measurement)，且感知发起设备(Sensing Initiator)不参与或参与部分感知测量(Sensing Measurement)或者感知测量实例(Sensing Measurement Instance)，那么意味着该感知发起设备(Sensing Initiator)是Non-AP STA(即STA1)。如图29所示，在这种场景下，STA1可以发送感知发起请求帧(Sensing Initialing Request frame)给AP(即感知响应设备1)，让AP去跟各个参与感知测量(Sensing Measurement)的感知响应设备(Sensing Responder)(2～N或者也可以包括Sensing Initiator)进行一对一的感知建立(Sensing Setup)，最后AP将Sensing Setup的结果通过感知发起响应帧(Sensing Initiating Response frame)反馈给Sensing Initiator。
在一些实施例中，感知测量结果通过感知报告帧(Sensing Report frame)发送。具体的，如图30所示，定义了感知动作帧(Sensing Action frame)：一种新的动作帧(Action frame)或无确认动作帧(Action No Ack)，动作类别(Category)为4表示该帧为公共动作帧(Public Action frame)，公共动作子类(Public Acton Field)值为46表示该帧为感知动作帧(可以用46～255范围内任意数值来表示该帧为感知动作帧)，感知子类(Sensing Subtype)值为6(可以用0～255范围内任意数值)指示为感知上报帧(Sensing Report frame)。

本申请实施例中，当有多个设备参与感知测量时，根据感知发起设备(Sensing Initiator)是否参与后续的感知测量(Sensing Measurement)，设计了感知发起设备(Sensing Initiator)直接与至少一个感知响应设备(Sensing Responder)进行成对(Pairwise)的感知建立(Sensing Setup)的机制和感知发起设备(Sensing Initiator)请求AP代理与各个感知响应设备(Sensing Responder)进行成对(Pairwise)的感知建立(Sensing Setup)的机制。在符合成对(Pairwise)的感知规则的前提下，提升了感知建立(Sensing Setup)的效率。
本申请实施例中，当参与感知测量的设备既支持发送(Transmit)又支持接收(Receive)时，设计了双向的感知测量(Sensing Measurement)机制，同时设计的NDPA帧还可以指示某个感知测量实例(Sensing Measurement Instance)执行单向Sensing Measurement还是双向Sensing Measurement。此外，NDPA帧可以指示单向Sensing Measurement时由谁发送NDP，且还可以指示在执行双向Sensing Measurement时NDP的发送顺序。提升了感知测量的灵活度。
因此，本申请实施例中，对于单向发送NDP，可以通过NDPA指示发送NDP的设备，对于双向发送NDP，能够通过NDPA指示发送NDP的顺序，从而，可以实现non-TB感知测量，在符合成对(Pairwise)感知测量的前提下，提升了感知建立的效率和感知测量的灵活性。
