  • Radar sensing is a wireless sensing technology. Radar consists of a transmitting antenna and a receiving antenna. The transmitting antenna sends electromagnetic waves, which are reflected when encountering the target, and the reflected waves are received by the receiving antenna. The radar system analyzes the characteristic information of the target, such as position, shape, motion characteristics and motion trajectory, through signal processing based on the changes in the transmitting and receiving waves. Radar sensing has many unique advantages. For example, radar is not affected by light brightness and has the ability to penetrate obstructions, which can better protect personal privacy; radar sensing has a longer distance and will not cause harm to humans and animals. The advantage of using radar technology to achieve perception is mainly reflected in the detection of motion.

图1为本申请实施例适用的一种应用场景的示意图。如图1所示，本申请提供的资源配置的方法适用于站点(station，STA)之间的数据通信，其中，站点可以是接入点(access point,AP)类的站点，也可以是非接入点类的站点(none access point station，non-AP STA)，分别简称为AP和非AP站点。具体地，本申请的方案适用于AP与一个或多个非AP站点之间的数据通信(例如，AP1与non-AP STA1、non-AP STA2之间的数据通信)，也适用于AP与AP之间的数据通信(例如，AP1与AP2之间的数据通信)，以及，non-AP STA与non-AP STA之间的数据通信(例如，non-AP STA2与non-AP STA3之间的数据通信)。
其中，接入点可以为终端(例如，手机)进入有线(或无线)网络的接入点，主要部署于家庭、大楼内部以及园区内部，典型覆盖半径为几十米至上百米，当然，也可以部署于户外。接入点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。
具体的，接入点可以是带有Wi-Fi芯片的终端或者网络设备，该网络设备可以为服务器、路由器、交换机、网桥、计算机、手机、中继站、车载设备、可穿戴设备、5G网络中的网络设备以及未来6G网络中的网络设备或者公用陆地移动通信网络(public land mobile network，PLMN)中的网络设备等，本申请实施例并不限定。接入点可以为支持Wi-Fi制式的设备。例如，接入点也可以支持802.11a、802.11b、802.11g、802.11n、802.11ac、802.11ax、802.11be、802.11ad、802.11ay等电气和电子工程师学会(Institute of Electrical and Electronics Engineers，IEEE)802.11家族的一种或多种标准。
非AP站点可以为无线通讯芯片、无线传感器或无线通信终端等，也可称为用户、用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。非AP站点可以是蜂窝电话、无绳电话、会话 启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、物联网设备、可穿戴设备、5G网络中的终端设备、未来6G网络中的终端设备或者PLMN中的终端设备等，本申请实施例对此并不限定。非AP站点可以为支持WLAN制式的设备。例如，非AP站点可以支持802.11a、802.11b、802.11g、802.11n、802.11ac、802.11ax、802.11be、802.11ad、802.11ay等IEEE 802.11家族的一种或多种标准。

雷达感知是一种无线感知技术，雷达由发射天线和接收天线组成，发射天线会发送电磁波，电磁波遇到目标会发生反射，反射波会被接收天线接收。雷达系统会根据发射波和接收波的变化，通过信号处理，分析出目标的特征信息，例如位置、形状、运动特性和运动轨迹等。雷达感知具有许多独特的优势，例如，雷达不受光线明暗的影响，具有穿透遮挡物的能力，可以更好地保护个人隐私；雷达感知的距离更远，不会对人和动物造成伤害。利用雷达技术实现感知的优势主要体现在对于运动的检测，通过对目标回波的多普勒效应来观测和解读目标的运动状态，如运动方向和运动速度。
在WLAN中引入感知技术具有很好的商业前景，无线感知(Wi-Fi sensing)技术可以应用在不同的场景中，例如，在体育运动中，可以通过这项技术检测人和球类的运动状态和运动轨迹。又如，在居家环境下，还可以做人体摔倒检测，用于预防老人摔倒。无线感知技术可以充分利用现存的WLAN网络资源，无需大量成本。在未来的密集部署的WLAN中，一个AP覆盖范围内有很多个non-AP STA，AP可以对每个non-AP STA进行合理的资源调度来提高系统的吞吐量、鲁棒性等。
802.11bf协议支持在Sub-7GHz频段和高频(例如，60GHz)频段实现感知。在Sub-7GHz频段，感知是通过对无线信道进行探测，估计信道状态信息(channel state information，CSI)，从而实现动作识别、运动轨迹追踪、摔倒检测等目的。在60GHz频段，感知是通过对环境进行定向波束扫描，得到距离多普勒谱(range doppler map，RD Map)来获取目标状态信息和环境信息。通过调节发射天线的相位，无线信号的能量会聚集在某一方向，形成一个指向性(或定向)波束(beam)。定向波束的波束宽度较窄，能量更集中，因此具有更高的天线增益，且减少了对其他接收信号的干扰。
下面对感知过程的一些概念进行简单介绍。
1.感知中的角色
WLAN感知技术中可以包括以下几种角色。应理解，在一些场景中，以下不同的角色可以由同一个设备执行。
1)感知发起端：发起一个感知过程的站点。
sensing initiator:a STA that initiates a WLAN sensing procedure.
2)感知响应端：参与一个由感知发起端发起的感知过程的站点。
sensing responder:a STA that participates in a WLAN sensing procedure initiated by a sensing initiator.
3)感知发送端：在感知过程内发送用于感知测量的物理层协议数据单元(physical protocol data unit,PPDU)的站点。
sensing transmitter:a STA that transmits PPDUs used for sensing measurements in a sensing procedure.
4)感知接收端：在感知过程内接收感知发送端发送的PPDU且进行感知测量的站点。
sensing receiver:a STA that receives PPDUs sent by a sensing transmitter and performs sensing measurements in a sensing procedure.
在SBP中，感知中的角色还包括：
5)代理感知发起端(SBP initiator)：发起一个代理感知过程的站点。
6)代理感知响应端(SBP responder)：参与一个由代理感知发起端发起的代理感知过程的站点，作为感知过程里的感知发起端。
2.感知过程
感知过程可以用于描述如何进行感知，感知过程可以包括以下5个步骤：
1)感知时段建立(sensing session setup)：表示站点间建立一个感知时段。感知相关的一些参数可以在这里交互(具体待定)。注意：感知时段是一个感知发起端和一个感知响应端达成的两站点间的协议。一个感知发起端可以与多个感知响应端保持感知时段，但仍然需要一个个建立，例如，通过正交频分多址接入(orthogonal frequency division multiple access，OFDMA)方式、多用户-多输入多输出(multi-user multiple-input multiple-output，MU-MIMO)方式等。感知时段也可以称为感知会话。
2)感知测量建立(sensing measurement setup)：用于感知发起端与响应端交换和统一某些在感知过程中需要使用的参数、属性等，例如，感知发起端、响应端的角色、测量反馈类型等参数，例如，响应端的角色可以包括感知发送端、感知接收端。感知测量建立可以简称为测量建立。感知测量建立可以通过感知测量建立标识(sensing measurement setup ID)进行标识。
3)感知测量实体(sensing measurement instance)：感知测量发生在感知测量实体中，一个感知测量实体中允许多个感知响应端的加入。感知测量实体建立又可以称为感知测量实例，感知测量实体可以简称为测量实体或实体。每一个感知测量实体可以通过感知测量实体标识(sensing measurement instance ID)进行标识。
4)感知测量建立终止(sensing measurement setup termination)：感知测量建立终止用于终于某个感知响应端对应的measurement setup的过程，终止后该感知响应端不再与对应的measurement setup绑定，但可以仍在感知时段中。感知测量建立终止可以简称为测量建立终止。
5)感知时段终止(sensing session termination)：表示感知时段的终止，站点不再参与感知测量等过程。
3.高频感知的类型
在IEEE 802.11bf协议里，一个感知会话由一个感知发起端(sensing initiator)发起，由一个或多个感知响应端(sensing responder)参与。协议里规定了五种高频感知的类型，分别是单站(monostatic)感知、双站(bistatic)感知、多站(multistatic)感知、单站协同(monostatic with coordination)感知和双站协同(bistatic with coordination)感知。
图2示出了上述五种高频感知的类型。其中，高频感知指的是IEEE 802.11bf协议里定义的DMG感知或EDMG感知。对于高频感知，当发送端和接收端是同一设备时，可以称为自发自收。当发送端和接收端是不同设备时，可以称为收发分置。在图2中，TX表示感知发送端(transmitter)，RX表示感知接收端(receiver)。
图2的(a)示出的是单站感知，如图2的(a)所示，在单站感知中，感知发起端既是感知发送端，也是感知接收端，它接收自己发送的感知PPDU进行感知测量，即自发自收。
图2的(b)和图2的(c)示出的是双站感知，如图2的(b)和(c)所示，在双站感知中，感知发起端和感知响应端分别承担感知发送端和感知接收端中的一个角色，即一发一收，感知发送端发送感知PPDU给感知接收端，由感知接收端进行感知测量。在图2的(b)中，感知发起端作为感知发送端，感知响应端作为感知接收端。在图2的(c)中，感知发起端作为感知接收端，感知响应端作为感知发送端。
图2的(d)示出的是多站感知，如图2的(d)所示，在多站感知中，感知发起端作为感知发送端，发送一个感知PPDU给多个感知响应端，即一发多收，这些感知响应端作为感知接收端进行感知测量。
图2的(e)示出的是单站协同感知，如图2的(e)所示，在单站协同感知中，感知发起端让一个或多个感知响应端做自发自收的感知测量。
图2的(f)、图2的(g)和图2的(h)示出的是双站协同感知。如图2的(f)、(g)和(h)所示，在双站协同感知中，感知发起端和多个感知响应端分别进行一发一收的感知测量。在图2的(f)中，感知发起端作为感知发送端，多个感知响应端分别作为感知接收端。在图2的(g)中，感知发起端作为感知接收端，多个感知响应端分别作为感知发送端。在图2的(h)中，一个感知响应端作为感知发送端，另一个感知响应端作为感知接收端，即作为TX的感知响应端发送感知PPDU给作为RX的另一个感知响应端，后者进行感知测量，之后会将测量结果反馈给感知发起端。此外，在图2的(h) 中，感知发起端既是感知发送端，也是感知接收端，一个感知响应端可以向感知发起端发送感知PPDU，该感知发起端也可以向另一个感知响应端发送感知PPDU。
由图2可以看出，在单站感知、双站感知中，感知发起端可以为AP或non-AP STA，感知响应端也可以为AP或non-AP STA，在多站感知、单站协同感知和双站协同感知中，感知发起端通常为AP，感知响应端通常为non-AP STA。
4.基于代理的感知(sensing by proxy，SBP)
基于代理的感知指的是，第一站点(例如，non-AP STA)可以请求第二站点(例如，AP)执行WLAN感知，并请求该第二站点将感知结果反馈给自己。这个发起SBP流程的站点(第一站点)被称为SBP发起端(SBP initiator)，被请求的站点(第二站点)作为代理(proxy)参与SBP，被请求的站点被称为SBP响应端(SBP responder)，同时被请求的站点也是SBP感知流程里的感知发起端(sensing initiator)，参与SBP响应端发起的感知流程的一方或多方为感知响应端。
5.高频感知中的SBP
对应于图2所示的高频感知的五种类型，高频感知中的SBP也可以分为五种类型，分别为单站SBP(SBP with monostatic)、双站SBP(SBP with bistatic)、多站SBP(SBP with multistatic)、单站协同SBP(SBP with monostatic with coordination)、双站协同SBP(SBP with bistatic with coordination)。与图2不同的是，在SBP中，SBP发起端可以请求SBP响应端执行感知流程，SBP响应端作为感知发起端，与感知响应端进行感知，感知发起端最终可以将感知结果反馈给SBP发起端。
图3示出了高频感知中基于代理的感知的五种类型。如图3所示，在任一种SBP类型中，SBP发起端和SBP响应端之间通过交互SBP请求帧和SBP响应帧，从而SBP响应端可以作为感知发起端，进一步，感知发起端可以将感知结果通过SBP报告帧反馈给SBP发起端。与图2类似，在图3中，TX表示感知发送端(transmitter)，RX表示感知接收端(receiver)。另外，在图3所示的高频SBP中，SBP发起端和SBP响应端是用于WLAN高频感知中的设备，其可以分别称为DMG SBP发起端和DMG SBP响应端。类似地，SBP请求帧、SBP响应帧、SBP报告帧、SBP终止帧是用于WLAN高频感知中的帧，分别又可以称为DMG SBP请求帧、DMG SBP响应帧、DMG SBP报告帧、DMG SBP终止帧。
图3的(a)示出的是单站SBP，与图2的(a)类似，在图3的(a)中，感知发起端既是感知发送端，也是感知接收端，它接收自己发送的感知PPDU进行感知测量，即自发自收。与图2的(a)不同的是，在图3的(a)中，感知发起端可以进一步将感知结果反馈给DMG SBP发起端。
图3的(b)和图3的(c)示出的是双站SBP，与图2的(b)类似，在图3的(b)中，感知发起端作为感知发送端，感知响应端作为感知接收端，感知接收端可以将感知结果反馈给感知发起端。与图2的(c)类似，在图3的(c)中，感知发起端作为感知接收端，感知响应端作为感知发送端。与图2的(b)、(c)不同的是，在图3的(b)、(c)中，感知发起端可以进一步将感知结果反馈给DMG SBP发起端。
图3的(d)示出的是多站SBP，与图2的(d)类似，在图3的(d)中，感知发起端作为感知发送端，发送一个感知PPDU给多个感知响应端，即一发多收，这些感知响应端作为感知接收端进行感知测量，这些感知接收端可以将感知结果反馈给感知发起端。与图2的(d)不同的是，在图3的(d)中，感知发起端可以进一步将感知结果反馈给DMG SBP发起端。
图3的(e)示出的是单站协同SBP，与图2的(e)类似，在图3的(e)中，感知发起端让一个或多个感知响应端做自发自收的感知测量，感知接收端可以将感知结果反馈给感知发起端。与图2的(e)不同的是，在这种SBP类型中，DMG SBP发起端还可以请求让感知发起端做自发自收的感知。此外，在图3的(e)中，感知发起端可以进一步将感知结果反馈给DMG SBP发起端。
图3的(f)、图3的(g)和图3的(h)示出的是双站协同SBP。与图2的(f)类似，在图3的(f)中，感知发起端作为感知发送端，多个感知响应端分别作为感知接收端。与图2的(g)类似，在图3的(g)中，感知发起端作为感知接收端，多个感知响应端分别作为感知发送端，感知接收端可以将感知结果反馈给感知发起端。与图2的(h)类似，在图3的(h)中，一个感知响应端作为感知发送端，另一个感知响应端作为感知接收端，即作为TX的感知响应端发送感知PPDU给作为RX的另一个感知响应端，后者进行感知测量，之后会将测量结果反馈给感知发起端。此外，在图3的(h)中，感知发起端既是感知发送端，也是感知接收端，一个感知响应端可以向感知发起端发送感知PPDU， 该感知发起端也可以向另一个感知响应端发送感知PPDU。与图2的(f)、(g)、(h)不同的是，在图3的(f)、(g)、(h)中，感知发起端可以进一步将感知结果反馈给DMG SBP发起端。
由图3可以看出，在单站SBP、双站SBP中，SBP发起端可以为AP或non-AP STA，SBP响应端(即感知发起端)可以为AP或non-AP STA，感知响应端也可以为AP或non-AP STA。在多站SBP、单站协同SBP和双站协同SBP中，SBP发起端通常为non-AP STA，SBP响应端(即感知发起端)通常为AP，感知响应端通常为non-AP STA。应理解，图3仅为本申请的应用场景的几种示例，并不构成本申请的限定。例如，在多站SBP、单站协同SBP和双站协同SBP中，SBP发起端也可以为AP，SBP响应端(即感知发起端)也可以为non-AP STA，感知响应端也可以为AP。
6.SBP流程
图4是一种SBP的流程示意图。图4示出的是IEEE 802.11bf协议中对Sub-7GHz频段定义的SBP的流程。如图4所示，该流程可以包括以下步骤。
S101，SBP发起端发送SBP请求(SBP request)帧给SBP响应端，该帧里包括SBP流程的配置参数。
S102，收到SBP请求帧后，SBP响应端会回复SBP响应(SBP response)帧。
如果SBP请求帧配置参数符合SBP响应端的设置，SBP响应帧会表示接受SBP请求，SBP建立成功，否则，拒绝SBP请求，SBP建立失败。
S101至S102可以称为SBP建立(SBP setup)阶段。当SBP建立成功后，SBP响应端作为感知发起端会向一个或多个感知响应端发起感知流程，该感知流程包括感知测量建立(sensing measurement setup)阶段和感知测量实体(sensing measurement instance)阶段。感知测量建立阶段包括S103至S104。
S103，SBP响应端向感知响应端发送感知测量建立请求(sensing measurement setup request)帧。
感知测量建立请求帧中包括感知测量建立标识(sensing measurement setup ID)和一个或多个感知测量建立参数元素(sensing measurement setup parameters element)。
S104，感知响应端向SBP响应端发送感知测量建立响应(sensing measurement setup response)帧。
感知测量建立响应帧中包括响应于感知测量建立请求的状态码(status code)和/或一个或多个感知测量建立参数元素(sensing measurement setup parameters element)。
S105，感知响应端和SBP响应端进行感知测量。
在Sub-7GHz频段进行的感知测量为基于触发(trigger based，TB)类型的感知测量。感知测量包括感知响应端和SBP响应端中的一端发送感知PPDU，另一端获得感知测量结果。如果感知响应端作为感知接收端获得感知测量结果，那么感知响应端可以将感知测量结果发给SBP响应端。
S106，SBP响应端在获得感知测量结果后，将感知测量结果通过SBP报告(SBP report)帧反馈给SBP发起端。
S106为SBP报告(SBP reporting)阶段。S107至S108为SBP终止(SBP termination)阶段，SBP可以由SBP发起端或SBP响应端任一方终止，通过发送SBP终止(SBP termination)帧。
S107，SBP发起端发送SBP终止帧，终止SBP流程。
S108，SBP响应端发送SBP终止帧，终止SBP流程。
图4所示的SBP流程主要针对Sub-7GHz频段设计的，然而，在高频感知中，发送和检测的是方向性的信号，对位置的变化和遮挡更加敏感，很有可能因为位置移动导致与感知发起端连接中断，如果沿用Sub-7GHz频段的流程的话，很可能会因为SBP响应端掌握的已知信息与SBP建立时的当下信息不符而导致额外的信令开销，降低SBP建立的成功率和效率。例如，在图4中，SBP响应端在接收到SBP请求帧后，会根据感知响应端的能力和信息回复是否接受SBP请求，但这些信息很可能是过时的或不准确的。比如，SBP响应端知道与自己关联的设备中有5个设备具备感知的能力，当SBP请求帧里要求4个感知响应端参与感知时，SBP响应端可以接受该请求。但是，在接受请求后，SBP响应端在后续的感知测量建立阶段，只能与2个感知设备建立感知测量，另外3个感知设备很可能因为位置移动了，或被物理遮挡了等原因没办法进行感知测量。这样的话，SBP响应端需要发送SBP终止帧来终止SBP流程，使得SBP建立失败。
有鉴于此，本申请提供一种感知的方法和通信装置，SBP响应端可以根据感知响应端感知测量建立的结果来确定是否接受SBP请求，在感知测量建立的结果为成功时，接受SBP请求，从而能够提高 SBP建立的成功率，进而提升感知效率。
在本申请中，消息可以理解为帧，消息中的信息或参数可以理解为帧中的字段(field)，或者说，消息中的信息或参数通过帧中的字段表示。此外，本申请中的字段指的是广义的字段，在一些情况下，字段又可以称为域、元素、子元素或子字段等。
图5是本申请实施例提供的一种感知的方法200的示意性流程图。图5可参考上述图1至图4中的描述。方法200可以用于DMG SBP建立阶段。

作为示例，第二消息可以为SBP响应帧(SBP response)，第一SBP是否建立成功的信息可以为SBP响应帧中的状态码(status code)字段。
可选地，第二消息还可以包括第一SBP的标识。例如，第一SBP的标识可以为对话令牌(dialog token)的值，对话令牌可以用于标记SBP请求，该对话令牌的值可以与SBP发起端在SBP请求帧中设置的对话令牌的值相同。
其中，第二消息根据第一消息确定。或者说，第二消息由第一消息确定。或者说，SBP响应端根据感知响应端是否接受第一感知测量建立来确定第一SBP建立是否成功。
例如，第一消息中包括感知响应端接受第一感知测量建立的信息，则第二消息包括第一SBP建立成功的信息。又如，第一消息中包括感知响应端拒绝第一感知测量建立的信息，则第二消息包括第一SBP建立失败的信息。
可选地，S210中的步骤可以由多个感知响应端执行，换言之，多个感知响应端可以均向同一个SBP响应端发送第一消息。这种情况下，第二消息根据第一消息确定，可以理解为，SBP响应端根据多个感知响应端是否接受第一感知测量建立来确定第一SBP是否建立成功。例如，当多个感知响应端中有X个感知响应端接受第一感知测量建立时，SBP响应端确定第一SBP建立成功，其中，X可以为预设值。
作为示例，该预设值可以在S210之前由SBP发起端向SBP响应端指示，也可以为协议预定义的方式。
可选地，在本申请中，感知响应端可以为AP，也可以为non-AP STA。类似地，SBP响应端可以为AP，也可以为non-AP STA。SBP发起端可以为AP，也可以为non-AP STA。SBP发起端、SBP响应端、感知响应端具体为AP或non-AP STA视感知类型而定，可以参考图3。
基于上述方案，SBP响应端可以根据感知测量建立的结果来确定是否SBP建立的结果，在感知测量建立的结果为成功时，发送SBP建立成功的信息，在感知测量建立结果为失败时，发送SBP建立失 败的信息，从而能够提高SBP建立的成功率，进而提升感知效率。
可选地，在S210之前，该方法200还包括：S230，SBP发起端向SBP响应端发送第三消息，相应地，SBP响应端接收来自SBP发起端的第三消息。
其中，第三消息用于请求建立第一SBP，或者说，第三消息用于发起第一SBP的建立。
其中，第三消息包括第一感知测量建立的配置参数。或者说，第三消息包括用于配置SBP中的感知测量建立的参数。或者说，第三消息包括不同感知类型的感知的参数，该感知类型可以为图3所示的任一种。
此外，感知测量建立的配置参数可以包括以下一种或多种参数：感知测量建立过程所需的参数、感知测量过程所需的参数、或感知测量完成后的反馈参数等。
作为示例，第三消息可以为SBP请求帧(SBP request)，第二消息可以视为第三消息的响应。
基于上述方案，SBP发起端可以在第三消息中请求感知测量建立的配置参数，进一步，SBP响应端可以根据该配置参数确定与感知响应端进行感知测量建立的参数，如此，使得SBP发起端可以更加灵活全面地控制和管理SBP流程。
可选地，第三消息还可以包括第一SBP的标识。例如，第一SBP的标识可以为对话令牌(dialog token)的值，对话令牌可以用于标记本次发起的SBP请求。
可选地，第三消息还可以包括第一感知测量建立的标识。换言之，第一感知测量建立的标识可以由SBP发起端确定，这种情况下，SBP发起端可以在第三消息中携带第一感知测量建立的标识，SBP响应端在第二消息中携带该第一感知测量建立的标识。
可选地，第一感知测量建立的标识由SBP响应端确定，在这种情况下，SBP发起端第三消息中可以不携带感知测量建立的标识，SBP响应端在确定第一感知测量建立的标识后，在第二消息中携带该第一感知测量建立的标识。
基于上述方案，感知测量建立标识可以由SBP发起端确定，也可以由SBP响应端确定，如此，能够提高SBP流程的灵活性。
可选地，在S230之后，且在S210之前，该方法200还包括：S240，SBP响应端向感知响应端发送第四消息，相应地，感知响应端接收来自SBP响应端的第四消息。
其中，第四消息用于请求发起第一感知测量建立。
其中，第四消息根据第三消息确定，或者说，第四消息包括第三消息中的部分信息。例如，第三消息中包括感知响应端#1为感知接收端，此时SBP响应端可以通过第四消息将感知响应端#1配置为感知接收端。又如，第三消息中包括感知响应端的个数为5，SBP响应端可以通过第四消息与5个感知响应端发起感知测量建立。
作为示例，第四消息可以为测量建立请求帧(measurement setup request)，第一消息可以视为第四消息的响应。
基于上述方案，SBP响应端可以根据SBP发起端发送的配置参数确定与感知响应端进行感知测量建立的参数，如此，使得SBP发起端可以更加灵活全面地控制和管理SBP流程。
可选地，若第一SBP建立失败，则第二消息还可以包括第一感知测量建立的建议参数，该建议参数可以理解为SBP响应端针对第一SBP可以接受的参数。例如，SBP请求帧中指示感知响应端的数量为5，SBP响应端在后续的感知测量建立阶段，只能与3个感知响应端建立感知测量，SBP响应端可以在第二消息中指示SBP建立失败，还可以携带信息指示感知响应端的建议数量为3。
应理解，在本申请方法200中，SBP发起端和SBP响应端可以是用于WLAN高频感知中的设备，其可以分别称为DMG SBP发起端和DMG SBP响应端。类似地，SBP请求帧、SBP响应帧是用于WLAN高频感知中的帧，其又可以称为DMG SBP请求帧、DMG SBP响应帧。可选地，本申请方法200也可以用于Sub-7GHz频段，不予限制。以下为了便于说明，以DMG SBP发起端、DMG SBP响应端、DMG SBP请求帧、DMG SBP响应帧为例进行说明。
下面对本申请提供的DMG SBP请求帧的配置参数进行详细说明，该配置参数可以包括SBP特有的参数和DMG感知通用参数至少一种。SBP特有的参数可以放在DMG SBP参数元素(DMG SBP Parameters element)中，DMG感知通用参数可以复用DMG感知已有的DMG感知测量建立元素(DMG Sensing Measurement Setup element)来表示，SBP特有的参数包括DMG SBP参数元素中的至少一个参 数，DMG感知通用参数包括DMG感知测量建立元素中的至少一个参数。
具体地，DMG SBP请求帧是一个动作(action)帧，由DMG SBP发起端发送给DMG SBP响应端，DMG SBP请求帧的动作字段(action field)可以包括如表1所示的至少一个字段。
表1
作为示例，S230中的“第一感知测量建立的配置参数”可以包括DMG SBP参数元素的至少一个字段、和/或DMG感知测量建立元素中的至少一个字段所携带的信息。
表2

表3


表4
应理解，在表4中，DMG TX-RX Pair 1至Q在DMG TX-RX对子元素的排序可以表示每个配对的感知测量顺序。即可以按照DMG TX-RX对1、DMG TX-RX对2、……、DMG TX-RX对Q依次进行感知测量。
表5
图6示出的是DMG感知测量建立元素的格式示意图。该DMG感知测量建立元素可以用于DMG感知测量建立中，如图6所示，该元素包括以下至少一个字段：元素标识(element ID)字段、长度(length)字段、元素标识扩展(element ID extension)字段、测量建立控制(measurement setup control)字段、报告类型(report type)字段、位置配置信息(location configuration information，LCI)字段、同伴方向(peer orientation)字段和可选的子元素(optional subelements)。其中，测量建立控制字段包括以下至少一个字段：感知类型(sensing type)字段、RX发起端(RX initator)字段、LCI出现(LCI present)字段、方向出现字段(orientation present)字段和预留(reserved)字段，所谓RX发起端，也就是作为感知接收端的发起者。
其中，感知类型字段用在DMG SBP请求帧中表示在DMG SBP请求过程中执行的感知类型。该字段共3比特，取值0至3已经定义，4-7为预留比特。表6为感知类型字段的含义。
表6
这里没有单站类型的指示，但是在SBP中，DMG SBP发起端可以请求进行单站SBP，所以可以有两种方式达到这个目的：一种方式是通过表2中的Monostatic field，另一种方式是在表6中，用数值4表示单站类型。
在上述DMG SBP请求帧的示例中，感知类型字段可以用于指示在DMG SBP请求过程中执行的感知类型。此外，对于单站类型，除了通过表6中的取值指示，还可以通过表2中的单站(monostatic)字段指示。换言之，感知类型字段或单站字段可以携带第七信息，第七信息用于指示SBP的类型为单站类型。此外，感知类型字段还可以携带第一信息或第四信息，第一信息用于指示SBP的类型为双站协同，第四信息用于指示SBP的类型为单站协同。
对于双站协同SBP类型，例如，如图3的(h)所示，感知响应端中有一部分作为感知发送端，另一部分作为感知接收端，本申请中，将作为感知发送端的感知响应端称为第一感知响应端，SBP发起端中指示的第一感知响应端可以为一个，也可以为多个。类似地，作为感知接收端的感知响应端可以称为第二感知响应端，SBP发起端中指示的第二感知响应端可以为一个，也可以为多个。因此，表2中的作为TX的DMG感知响应端地址字段、作为TX的DMG感知响应端的标识字段以及表3中的作为TX的DMG感知响应端的数量字段、作为TX的DMG感知响应端的数量的强制性字段、可参考的作为TX的DMG感知响应端的数量字段均可以视为第一感知响应端的信息，表2中的作为RX的DMG感知响应端地址字段、作为RX的DMG感知响应端的标识字段以及表3中的作为RX的DMG感知响应端的数量字段、作为RX的DMG感知响应端的数量的强制性字段、可参考的作为RX的DMG感知响应端的数量字段均可以视为第二感知响应端的信息，进一步，第一感知响应端和第二感知响应端的信息可以均称为第二信息。换言之，第二信息可以携带于多个字段。
基于上述方案，DMG SBP请求帧中可以指示作为感知发送端的感知响应端的信息和作为感知接收端的感知响应端的信息，使得双站协同感知类型中的感知响应端之间的感知可以实现，能够提高感知的效率。
此外，对于双站协同SBP类型，在表2中，DMG TX-RX对子元素用于指示指示发生在感知响应端之间的感知PPDU的发送方向，换言之，DMG TX-RX对子元素用于指示第一感知响应端和第二感知响应端之间的对应关系，根据DMG TX-RX对子元素，DMG SBP响应端可以获知作为TX的感知响应端所对应的作为RX的感知响应端。例如，DMG TX-RX对子元素中的DMG TX-RX对1字段为A和B，因此，DMG SBP响应端可以获知A为RX，B为TX，也就是发生在感知响应端之间的感知PPDU的发送方向为由B到A。本申请中，DMG TX-RX对子元素携带的信息可以称为第三信息。
基于上述方案，DMG SBP请求帧中可以指示感知响应端之间的感知PPDU的发送方向，使得双站协同感知类型中的感知响应端之间的感知可以实现，能够提高感知的效率。
对于单站协同类型，表2中的顺序测量字段可以用于指示多个感知响应端同时或者按顺序进行感知测量，表3中的感知发起端单站请求字段可以用于指示DMG SBP响应端是否作为感知响应端参与单站感知，顺序测量字段携带的信息可以称为第五信息，感知发起端单站请求字段携带的信息可以称为第六信息。
对于上述任一种感知类型，表2中的DMG SBP报告控制字段用来设置和感知结果的反馈相关的参数，DMG SBP报告控制字段承载的信息可以称为第八信息。具体地，如表5所示，第八信息可以包括以下至少一项：每次测量结束后反馈或者多次测量结束后反馈、每次反馈一个感知响应端的感知测量结果或者一次反馈多个感知响应端的感知测量结果、反馈报告是否包括感知响应端的位置信息、反馈报告是否包括感知响应端的天线方向、反馈报告是否包括感知测量的发生时间，每一项可以通过表5中的一个字段携带。
基于上述方案，DMG SBP发起端通过请求与感知结果的反馈相关的参数，使得DMG SBP发起端可以管理DMG SBP报告帧的内容和反馈方式，从而能够提高感知结果的反馈的灵活性，提高感知效率。
可选地，SBP响应端在向感知响应端发送第四消息时，第四消息可以包括DMG感知测量建立元素，通过DMG感知测量建立元素向感知响应端配置测量建立的参数。为了支持双站协同(bistatic with coordination)类型中感知响应端之间做感知测量(前文提到的TX-RX，或者R2R)，图6所示的DMG感知测量建立元素(DMG Sensing Measurement Setup element)中可以新增字段用来设定TX或RX角色，在DMG SBP响应端获得作为TX的感知响应端的列表和作为RX的感知响应端的列表后，DMG SBP响应端可以根据该列表将感知响应端分别设置为TX或RX。作为一种实现方式，DMG SBP响应端可以通过DMG感知测量建立元素中测量建立控制字段来携带TX或RX的信息，感知响应端可以通过该 信息来确定其为TX或RX。例如，图6中的B6和B7可以设置为DMG R2R TX字段和DMG R2R RX字段，每个字段分别使用一个比特，DMG R2R TX字段置1，表示该感知响应端作为TX，DMG R2R RX字段置1，表示该感知响应端作为RX。
可选地，SBP发起端可以在一次SBP请求中请求多种类型的感知，换言之，图3所示的不同类型的SBP可以同时存在。在这种情况中，DMG SBP请求帧中可以包括一个或多个DMG感知测量建立元素，其中，每个DMG感知测量建立元素可以用于建立一个感知测量，并且每个DMG感知测量建立元素对应一个感知类型，每个DMG感知测量建立元素的格式可以如图6所示。
此外，在上述情况中，如果DMG感知测量建立标识由DMG SBP发起端确定，那么表1中的DMG感知测量建立标识字段可以设置为保留值，进一步，可以通过DMG SBP请求帧中的DMG感知测量建立元素来携带DMG感知测量建立标识。具体地，感知测量建立元素携带DMG感知测量建立标识的实现方式可以为：为了标识每个感知测量，每个DMG感知测量建立元素可以包括一个DMG感知测量建立标识(DMG sensing measurement setup ID)字段，DMG感知测量建立标识字段用于指示DMG感知测量建立标识。示例性地，DMG感知测量建立标识字段的长度可以为1个字节，其位置可以位于图6所示的元素标识扩展字段和测量建立控制字段之间。
可选地，当DMG SBP请求帧中可以包括多个DMG感知测量建立元素时，DMG SBP请求帧中也可以包括多个DMG SBP参数元素，多个DMG感知测量建立元素和多个DMG SBP参数元素可以一一对应，并且一个DMG感知测量建立元素和一个DMG SBP参数元素对应一个感知测量。
作为示例，当请求多种感知类型时，SBP建立成功表示所请求的全部类型的感知测量建立成功，SBP建立失败可以表示无法全部建立所请求类型的感知测量。此外，在DMG SBP响应帧可以指示哪些类型建立成功，DMG SBP发起端可以进一步判断是否重新发送DMG SBP请求帧，携带能够建立成功的感知类型。
可选地，DMG SBP发起端可以利用DMG感知测量建立元素中的报告类型(Report Type)这一字段来请求测量报告的类型，DMG SBP响应端可以根据该字段的请求要求其他感知响应端反馈该类型的测量报告。例如，如图6所示，报告类型字段的长度为1个字节，其中的取值1-7可以分别表示的报告类型为：信道状态信息(channel state information,CSI)、DMG感知图像距离方向(DMG sensing image range direction)、DMG感知图像距离-多普勒(DMG sensing image range-doppler)、DMG感知图像距离-方向(DMG sensing image range-direction)、DMG感知图像多普勒-方向(DMG sensing image doppler-direction)、DMG感知图像距离-多普勒方向(DMG sensing image range-doppler direction)、目标(target)。
可选地，DMG感知测量建立元素还包括DMG感知调度子元素(DMG sensing scheduling subelement)，DMG感知调度子元素用来设置测量发生的时间、频率、周期、次数等。例如，DMG SBP发起端可以使用DMG感知调度子元素请求感知发生的测量时间，DMG SBP响应端可以根据这一时间设定与其他感知响应端进行感知测量建立。DMG感知调度子元素可以包括如表7所示的至少一个字段，每个字段的含义也如表7所示，在表7中，字段长度的单位为字节。
表7

下面对本申请提供的DMG SBP响应帧的建议参数进行详细说明，该建议参数可以包括SBP特有的参数和DMG感知通用参数中至少一种。SBP特有的参数可以放在DMG SBP参数元素(DMG SBP Parameters element)中，DMG感知通用参数可以复用DMG感知已有的DMG感知测量建立元素(DMG Sensing Measurement Setup element)来表示，SBP特有的参数包括DMG SBP参数元素中的至少一个参数，DMG感知通用参数包括DMG感知测量建立元素中的至少一个参数。
具体地，DMG SBP响应帧也是一个动作帧。由DMG SBP响应端发送给DMG SBP发起端，DMG SBP响应帧的动作字段(action field)可以包括如表8所示的至少一个字段。
表8

应理解，DMG SBP响应帧中的DMG SBP参数元素、DMG感知测量建立元素包括的字段及每个字段承载的内容，可以参考DMG SBP请求帧中的DMG SBP参数元素、DMG感知测量建立元素，在此不赘述。这些字段在DMG SBP请求帧中，表示DMG SBP发起端请求的配置参数，在DMG SBP响应帧中，表示DMG SBP响应端的建议参数。例如，DMG SBP请求帧里关于SBP报告控制字段的配置，指的是DMG SBP发起端请求DMG SBP响应端的配置，即DMG SBP响应端应该如何向DMG SBP发起端反馈报告。DMG SBP响应帧里关于SBP报告控制字段的设置，指的是DMG SBP响应端希望的配置，即DMG SBP响应端希望可以如何向DMG SBP发起端反馈报告。
还应理解，如果DMG感知测量建立标识由DMG SBP响应端确定，那么表8中的DMG感知测量建立标识字段可以设置为保留值，进一步，可以通过DMG SBP响应帧中的DMG感知测量建立元素来携带DMG感知测量建立标识。其中，感知测量建立元素携带DMG感知测量建立标识的方式可以为：为了标识每个感知测量，每个DMG感知测量建立元素可以包括一个DMG感知测量建立标识字段，DMG感知测量建立标识字段用于指示DMG感知测量建立标识。示例性地，DMG感知测量建立标识字段的长度可以为1个字节，其位置可以位于图6所示的元素标识扩展字段和测量建立控制字段之间。
此外，如果DMG感知测量建立标识由DMG SBP响应端确定，那么DMG SBP请求帧中的DMG感知测量建立标识字段可以设置为保留值。如果DMG感知测量建立标识由DMG SBP发起端确定，那么DMG SBP响应帧中的DMG感知测量建立标识字段可以设置为保留值或重复DMG SBP请求帧中的DMG感知测量建立标识字段的数值。
基于上述方案，若第一SBP建立失败，则第二消息还可以包括第一感知测量建立的建议参数，如此，DMG SBP发起端可以根据DMG SBP响应帧中的建议参数重新发起DMG SBP请求，进而能够提高SBP建立的成功率，提升感知效率。
图7是本申请实施例提供的一种感知的方法300的示意性流程图。图7可参考上述图1至图6中的描述。方法300可以用于SBP报告阶段。
S310，SBP响应端生成第五消息。
其中，第五消息用于报告感知响应端的感知测量结果，或者说，第五消息携带感知响应端的感知测量报告，或者说，第五消息携带SBP报告。
作为示例，第五消息可以为SBP报告帧(SBP report)。
可选地，第五消息包括第一SBP的标识，例如，第一SBP的标识可以为对话令牌(dialog token)的值，对话令牌可以用于标记SBP请求，该对话令牌的值可以与SBP发起端在SBP请求帧中设置的对话令牌的值相同。
其中，若SBP响应端为感知发送端或者SBP响应端不作为感知响应端，则SBP响应端可以从感知接收端接收感知测量结果，若SBP响应端为感知接收端，则SBP响应端可以根据接收到的感知PPDU获得感知测量结果，
S320，SBP响应端向SBP发起端发送第五消息，相应地，SBP发起端接收来自SBP响应端的第五消息。
其中，SBP报告帧的反馈方式和SBP报告帧携带的参数应当和SBP发起端请求的一致，或者应当和SBP发起端与响应端的协商结果一致。
可选地，第五消息可以根据方法200中的第八信息确定，换言之SBP响应端根据SBP发起端的请求，向SBP发起端反馈响应的感知测量结果，且该感知测量结果是与感知响应端的相关的结果。例如，第八信息指示反馈报告包括感知响应端的位置信息，则SBP响应端可以向感知响应端请求其位置信息，从而SBP响应端可以从感知响应端获得其位置信息，并向SBP发起端反馈相应的位置信息。
作为示例，SBP报告帧的反馈包括以下两种方式：
方式一、SBP响应端反馈单一感知响应端的测量结果。
例如，SBP响应端可以在获得任一个感知响应端的感知测量结果后，向SBP发起端发送SBP报告 帧。
可选地，在方式一中，S310之前，SBP发起端可以向SBP响应端发送第八信息，第八信息包括每次反馈一个感知响应端的感知测量结果的指示，具体可以参考方法200。
方式二：DMG SBP响应端反馈多个感知响应端的测量结果。
例如，SBP响应端可以在获得多个感知响应端的感知测量结果后，向SBP发起端发送SBP报告帧。
作为示例，在方式二中，SBP响应端可以通过聚合的MAC协议数据单元(aggregated MAC protocol data unit，A-MPDU)进行反馈。
可选地，在方式二中，S310之前，SBP发起端可以向SBP响应端发送第八信息，第八信息包括一次反馈多个感知响应端的感知测量结果的指示，具体可以参考方法200。
应理解，SBP报告帧携带的参数与哪种反馈方式无关。
基于上述方案，SBP响应端可以通过不同的方式向SBP发起端报告感知测量结果，从而能够提高感知结果的反馈的灵活性，提高感知效率。
应理解，在本申请方法300中，SBP发起端和SBP响应端可以是用于WLAN高频感知中的设备，其可以分别称为DMG SBP发起端和DMG SBP响应端。类似地，SBP报告帧是用于WLAN高频感知中的帧，其又可以称为DMG SBP报告帧。可选地，本申请方法300也可以用于Sub-7GHz频段，不予限制。以下为了便于说明，以DMG SBP发起端、DMG SBP响应端、DMG SBP报告帧为例进行说明。

可选地，DMG SBP响应端在发送DMG SBP报告帧时，可以根据DMG SBP请求帧的请求，携带对应感知响应端的位置配置信息(LCI)、MAC地址或标识(例如，AID或USID)、天线朝向、对应测量发生的时间戳(Timestamp)等一项或多项。这些信息可以通过DMG感知报告控制元素和DMG感知报告元素承载。
可选地，第五消息可以包括第九信息，第九信息用于指示感知测量结果对应的感知发送端和感知接收端。
具体地，对于bistatic with coordination感知类型中发生在感知响应端之间的感知测量的情况，DMG SBP Report帧可以指示该报告对应哪一个TX-RX pair。
作为一种实现方式，可以使用TX和RX的ID，即TX Sensing Responder ID和RX Sensing Responder ID，这两个ID可以放在DMG感知报告控制字段中。例如，继续如图8所示，在DMG感知报告控制字段还可以包括以下至少一项：TX感知响应端信息子字段和RX感知响应端信息子字段，其分别用于指示本次报告对应的作为TX的感知响应端的信息和作为RX的感知响应端的信息。作为示例，TX感知响应端信息子字段和RX感知响应端信息子字段可以分别包括8个字节，此时，DMG感知报告控制字段可以扩展为19个字节。图8给出了TX感知响应端信息子字段所包括的内容的示例，如图8所示，TX感知响应端信息子字段可以包括以下至少一项：TX感知响应端标识子字段、TX感知响应端LCI子字段、TX感知响应端天线方向子字段，分别占用1、2、5个字节。其中，TX感知响应端LCI、TX感知响应端天线方向为可选的子字段。对于RX感知响应端信息子字段，情况是类似的，在此不赘述。
应理解，LCI可以携带于DMG感知报告元素中，也可以携带于TX感知响应端信息字段，或RX感知响应端信息字段，本申请不予限制。
基于上述方案，针对感知响应端之间的感知测量，SBP响应端可以向SBP发起端报告R2R(即作为感知发送端的感知响应端和作为感知接收端的感知响应端之间)的测量结果，如此，可以降低DMG SBP报告的错误率，提升感知效率。
图9是本申请实施例提供的一种感知的方法400的示意性流程图。图9可参考上述图1至图8中的描述。方法400可以用于SBP终止阶段。方法400可以包括以下三种方式：
方式一、SBP响应端和SBP发起端通过定时器终止第一SBP。
S410-a，SBP响应端启动第一定时器，并设置第一定时器的起始时长为第一时长。相应地，SBP发起端可以启动第二定时器，并设置第二定时器的起始时长为第一时长。
作为示例，第一时长可以是预设时长，一种实现方式是，在S410之前由SBP发起端向SBP响应端指示第一时长，例如，方法200中的SBP请求帧中可以携带第十信息，第十信息指示第一时长，其中，第十信息可以携带于DMG SBP过期指数字段，如表3所示，DMG SBP过期指数和第一时长之间存在对应关系，通过DMG SBP过期指数可以确定第一时长。又一种实现方式为，协议中可以预定义第一时长。
其中，SBP响应端可以在以下任一种情况启动第一定时器：例如，在发送第二消息后，或者在收到第二消息的肯定应答(Acknowledgement，ACK)后，或者，在发送第一个SBP报告帧后。类似地，SBP发起端可以在以下任一种情况启动第二定时器：例如，在收到第二消息后，或者，在发送第二消息的ACK后，或者在收到第一个SBP报告帧后。
应理解，在方法400中，第二消息指示第一SBP建立成功。
S420-a，SBP响应端在第一定时器到期时终止第一SBP。相应地，SBP发起端可以在第二定时器SBP到期时终止第一SBP。
应理解，定时器到期(expire)，可以理解为定时器超时，或者定时器归零。
可选地，在SBP响应端与SBP发起端交互感知测量结果时以及在SBP响应端和感知响应端执行进行感知测量时，第一定时器和第二定时器可以暂停。
具体地，DMG SBP发起端和DMG SBP响应端各自设置一个倒计时时钟，DMG SBP发起端从收到携带Status Code＝SUCCESS的DMG SBP Response帧开始计时，DMG SBP响应端从收到Ack(对应DMG SBP Response帧，表示DMG SBP发起端收到了DMG SBP Response帧)开始计时，即从DMG SBP建立成功开始计时。当有感知测量发生或结果反馈时，计时暂停，否则计时持续，当计时归零，表示DMG SBP终止。倒计时的时间即为第一时长，可以在DMG SBP Setup阶段交互，使用DMG SBP过期指数字段指示。
基于上述方案，SBP响应端和SBP发起端可以通过定时器终止第一SBP，如此，可以省去SBP终止流程，能够减少信令开销。
方式二：SBP响应端和SBP发起端通过SBP终止帧终止第一SBP。
S410-b，SBP响应端向SBP发起端发送第六消息，第六消息用于终止第一SBP。
S420-b，SBP发起端向SBP响应端发送第七消息，第七消息用于终止第一SBP。
作为示例，第六消息和第七消息可以为SBP终止帧(SBP termination)。
可选地，第六消息或第七信息包括第十一信息，第十一信息用于指示终止所有双站协同类型的SBP，或用于指示终止所有单站类型的SBP。
应理解，在本申请方法400中，SBP发起端和SBP响应端可以是用于WLAN高频感知中的设备，其可以分别称为DMG SBP发起端和DMG SBP响应端。类似地，SBP终止帧是用于WLAN高频感知中的帧，其又可以称为DMG SBP终止帧。可选地，本申请方法400也可以用于Sub-7GHz频段，不予限制。以下为了便于说明，以DMG SBP发起端、DMG SBP响应端、DMG SBP终止帧为例进行说明。
具体地，DMG SBP发起端或DMG SBP响应端发送DMG SBP Termination帧，按照感知类型对DMG SBP感知执行终止。SBP终止帧可以包括如表10所示至少一个字段。
表10
DMG SBP终止控制字段可以包括以下至少一项：终止所有单站协同建立(terminate all coordinated monostatic setups)字段、终止所有双站建立(terminate all bistatic setups)字段、终止所有多站建立(terminate all mutistatic setups)字段、DMG SBP建立未成功(DMG SBP setup unsuccess)字段、预留(reserved)字段。然而，目前缺少两种感知类型的终止指示。因此，在本申请中，DMG SBP终止控制字段还可以包括终止所有双站协同建立(terminate all coordinated bistatic setups)字段和终止所有单站建立(terminate all monostatic setups)字段中的至少一个，这两个字段分别占用1比特，用于指示是否终止所有双站协同建立，以及，用于指示是否终止所有单站建立。DMG SBP终止控制字段的示意图具体如图10所示。终止所有双站协同建立字段、终止所有单站建立字段携带的信息可以为第十一信息。
方式三：通过最后一个报告指示SBP终止。
具体地，可以在DMG SBP报告帧使用一个bit表示最后一个报告，即Last SBP Report，DMG SBP发起端收到最后一个报告的指示后自动终止DMG SBP，DMG SBP响应端发送后最后一个报告的指示后自动终止DMG SBP。DMG SBP报告帧的内容和格式可以参考方法300。
应理解，方法300中的方式一至方式三可以单独实施，也可以在某些场景中相互结合，本申请不予限制。
还应理解，上述方法200、方法300、方法400可以单独实施，也可以相互结合，不予限制。
此外，本申请中的帧格式、字段名称和字段长度等仅为示例性说明，这些帧格式、字段名称和字 段长度等也可以是其他格式，只要可以携带或指示相应的信息即可，本申请对具体格式不作限定。例如，表3中的DMG SBP过期指数字段为4比特，然而，该字段的长度也可以为其他值，比如2比特或8比特等。另外，本申请中，任一表格中的字段并不是必选地，在一些情况下，本申请中提供的消息可以仅包括文中提出的部分字段。类似地，图6、图8、图10示出的字段也不是必选地，在一些情况下，可以仅包括图中所示的部分字段。
图11是本申请实施例提供的一种感知的方法500的示意性流程图。该方法500可以视为方法200、300、400的结合一种具体实现。方法500中未详细描述的内容可以参考方法200、300、400。
S501，DMG SBP发起端向DMG SBP响应端发送DMG SBP请求帧(第三消息的一例)，该帧包括关于DMG SBP流程的配置参数，该配置参数具体可以参考表1至表8。
S502，收到DMG SBP请求帧后，DMG SBP响应端向一个或多个感知响应端发送DMG感知测量建立请求帧(第四消息的一例)。
DMG感知测量建立请求帧中包括感知测量建立标识和一个或多个感知测量建立参数元素。
S503，一个或多个感知响应端向DMG SBP响应端发送DMG感知测量建立响应帧(第一消息的一例)。
每个DMG感知测量建立响应帧中包括响应于感知测量建立请求的状态码(status code)，指示该感知响应端对应的感知测量建立是否成功，DMG感知测量建立响应帧还可以包括一个或多个感知测量建立参数元素。
S504，DMG SBP响应端回复SBP响应(SBP response)帧(第二消息的一例)。
如果一个或多个DMG感知测量建立响应帧的结果符合DMG SBP发起端的中的配置参数，SBP响应帧中会携带接受SBP请求的状态码，即状态码＝success。否则，状态码＝fail，标识SBP建立失败。
S501至S504可以称为DMG SBP建立(DMG SBP setup)阶段和感知测量建立阶段。
S505，感知响应端和DMG SBP响应端进行感知测量。
感知测量包括感知响应端和DMG SBP响应端中的一端发送感知PPDU，另一端获得感知测量结果。如果感知响应端作为感知接收端获得感知测量结果，那么感知响应端可以将感知测量结果发给DMG SBP响应端。
S506，SBP响应端在获得感知测量结果后，将感知测量结果通过DMG SBP报告(DMG SBP report)帧反馈给DMG SBP发起端。
S506为DMG SBP报告阶段。S506的具体过程可以参考方法300。
在S506之后，DMG SBP发起端和DMG SBP响应端可以终止DMG SBP流程，具体参考方法400。图5示出的是方法400中的方式二，包括S507和S508。
S507，DMG SBP发起端发送DMG SBP终止帧，终止DMG SBP流程。
S508，DMG SBP响应端发送DMG SBP终止帧，终止DMG SBP流程。
