应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。

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。
参与WLAN感知的WLAN设备可能包括如下角色(role)：
感知会话发起设备(Sensing Initiator)或称感知发起设备，发起感知会话(sensing session)并想要获知感知结果的设备；
感知会话响应设备(Sensing Responder)或称感知响应设备，参与sensing session的非Sensing Initiator的设备；
感知信号发送设备(Sensing Transmitter)或称感知发送设备，发起感知测量信号(sensing illumination signal)的设备；
感知信号接收设备(Sensing Receiver)或称感知接收设备，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；
感知会话参与设备(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，例如感知会话发起设备可以仅仅是感知会话发起设备，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。
例如，如图2中的A所示，STA1可以是感知会话发起设备(Sensing Initiator)，也可以是感知信号接收设备(Sensing Receiver)，还可以是感知处理设备(Sensing processor)；STA2可以是感知信号发送设备(Sensing Transmitter)。
又例如，如图2中的B所示，STA1可以是感知会话发起设备(Sensing Initiator)，也可以是感知信号发送设备(Sensing Transmitter)；STA2可以是感知信号接收设备(Sensing Receiver)，也可以是感知处理设备(Sensing processor)。
又例如，如图2中的C所示，STA1可以是感知会话发起设备(Sensing Initiator)，也可以是感知处理设备(Sensing processor)；STA2可以是感知信号接收设备(Sensing Receiver)；STA3可以是感知信号发送设备(Sensing Transmitter)。
又例如，如图2中的D所示，STA1可以是感知会话发起设备(Sensing Initiator)，也可以是感知信号接收设备(Sensing Receiver)，还可以是感知处理设备(Sensing processor)；STA2可以是感知信号发送设备(Sensing Transmitter)；STA3可以是感知信号发送设备(Sensing Transmitter)。
又例如，如图2中的E所示，STA1可以是感知会话发起设备(Sensing Initiator)，也可以是感知信号发送设备(Sensing Transmitter)，还可以是感知处理设备(Sensing processor)；STA2可以是感知信号接收设备(Sensing Receiver)；STA3可以是感知信号接收设备(Sensing Receiver)。
又例如，如图2中的F所示，STA1可以是感知会话发起设备(Sensing Initiator)；STA2可以是感知信号接收设备(Sensing Receiver)，也可以是感知处理设备(Sensing processor)；STA3可以是感知信号发送设备(Sensing Transmitter)；STA4可以是感知信号发送设备(Sensing Transmitter)。
又例如，如图2中的G所示，STA1可以是感知会话发起设备(Sensing Initiator)，也可以是感知信号发送设备(Sensing Transmitter)，还可以是感知信号接收设备(Sensing Receiver)，还可以是感知处理设备(Sensing processor)。

又例如，如图2中的J所示，STA1可以是感知会话发起设备(Sensing Initiator)，也可以是感知处理设备(Sensing processor)；STA2可以是感知信号发送设备(Sensing Transmitter)，也可以是感知信号接收设备(Sensing Receiver)；STA3可以是感知信号发送设备(Sensing Transmitter)，也可以是感知信号接收设备(Sensing Receiver)。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(包括感知信号发送设备和感知信号接收设备)，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，感知信号发送设备发送感知信号给感知信号接收设备。
感知上报阶段：上报测量结果，由应用场景决定，感知信号接收设备可能需要给感知会话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，感知信号接收设备上报感知测量结果，否则不上报感知测量结果。
感知会话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))。
在相关技术中，尚未讨论感知会话发起设备在发起感知会话时，具体的感知会话建立过程，例如，如何确定是否需要执行感知参数协商帧的交互流程，以及具体的感知会话结束流程，例如，是否执行感知参数释放的帧交互流程等。
有鉴于此，本申请实施例提供了一种感知会话建立的方法，感知会话发起设备可以根据待建立的目标感知会话的类型，确定执行的目标感知会话建立过程，例如，可以通过MLME-SAP接口服务原语指示目标感知会话的类型。以及提供了一种感知会话结束的方法，感知会话发起设备或感知会话响应设备可以根据待结束的感知会话的类型，确定执行的目标感知会话结束流程，例如，提供MLME-SAP接口原语指示待结束的目标感知会话的信息。
图3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，该方法200为感知会话建立的方法的示意性图。如图3所示，该方法200包括如下内容：
S210，感知会话发起设备根据待建立的目标感知会话的类型，执行目标感知会话建立流程。
在一些实施例中，目标感知会话的类型可以为成对协商(Pairwise negotiation)类型或称协商类型，或者，也可以为非成对协商类型或称非协商类型，例如随意(Opportunistic)类型，单站雷达(Monostatic radar)类型，或者，被动(Passive)类型。
应理解，对于非成对协商类型的感知会话，感知会话发起设备不需要进行感知会话参数的协商，即可执行感知测量。
例如，对于随意(Opportunistic)类型的感知会话，感知会话发起设备监听工作信道上的任何物理层协议数据单元(Physical Protocol Data Unit,PPDU)，进行测量。
例如，对于单站雷达(Monostatic radar)类型的感知会话，感知会话发起设备需要发送感知信号并接受该信号的反射信号，进行测量。
例如，对于被动(Passive)类型的感知会话，感知会话发起设备需要获取信标帧(Beacon)里的测量时间信息，并在该时间段监听其他STA所发送的用于感知的特定PPDU，进行测量。
应理解，本申请实施例可以适用于建立一个新的感知会话，或者，也可以适用于建立一个已有感知会话中新的测量建立，因此，在一些实施例中，S210可以替换为：
感知会话发起设备根据待建立的测量建立对应的感知会话的类型，执行目标感知会话建立流程。
也就是说，建立一个新的感知会话，或者，建立一个已有感知会话中的新的测量建立均可以根据感知会话的类型，执行相应的感知会话建立流程。即所述目标感知会话可以是新的感知会话，或者，也可以是已有的感知会话，或者说，已建立的感知会话。
例如，若所述目标感知会话为成对协商类型，所述感知会话发起设备为所述目标感知会话分配资源和/或向感知会话响应设备发送第一请求帧，所述第一请求帧用于请求进行所述目标感知会话的测量建立。
又例如，若目标感知会话为非成对协商类型，所述感知会话发起设备为所述非成对协商类型的感知会话分配资源。
在一些实施例中，所述感知会话发起设备为所述目标感知会话分配资源可以包括：所述感知会话发起设备为所述目标感知会话分配后续执行感知测量的资源，例如感知发送设备发送测量信号的资源，比如频率资源单元，空时流分配信息等。或者，也可以包括用于存储测量结果的存储资源，本申请并不限于此。
在一些实施例中，所述第一请求帧可以用于请求建立所述目标感知会话中的一个测量建立，或者多个测量建立。
在一些实施例中，所述第一请求帧或称测量建立请求帧。
在一些实施例中，所述感知会话发起设备通过媒体访问控制子层管理实体服务访问点(MAC sublayer management entity service access point，MLME-SAP)接口服务原语指示所述目标感知会话的类型。
在一些实施例中，所述目标感知会话的建立过程可以是基于该感知会话发起设备的上层应用的指示。例如，在确认需要建立目标感知会话时，该感知会话发起设备的上层应用调用站点管理实体(Station Management Entity，SME)提供的接口来发起感知会话建立流程，具体地，上层应用调用SME提供的接口，从而SME调用第一媒体访问控制子层管理实体服务访问点(MAC sublayer management entity service access point，MLME-SAP)接口原语实现感知会话的建立。
在一些实施例中，所述上层应用可以指MAC层之上的应用，例如Wi-Fi驱动程序或者wpa_supplicant工具类应用等。
在一些实施例中，所述第一MLME-SAP接口原语或称感知请求建立原语，记为MLME-SENSSETUP.request。
在一些实施例中，所述第一MLME-SAP接口原语用于指示目标感知会话的类型。或者，所述第一MLME-SAP接口原语用于指示根据目标感知会话的类型执行相应的感知会话建立流程。例如发起感知测量和/或发送第一请求帧。
在一些实施例中，所述第一MLME-SAP接口原语用于指示以下中的至少一项：
目标感知会话的类型，所述目标感知会话的会话标识，测量建立标识，测量的持续时长，测量的重复次数，测量的间隔时间，感知请求参数，其中，所述感知请求参数包括感知会话响应设备的身份标识，需要协商的感知会话的参数等。

MLME-SENSSETUP.request(

该感知会话发起设备的SME在第一MLME SAP接收原语中将目标感知会话的感知类型指示给该感知会话发起设备的媒体访问控制子层管理实体(MAC sublayer management entity，MLME)后，该MLME可以根据该目标感知会话的类型，执行相应的感知会话建立流程。
以下，结合目标感知会话的类型，对目标感知会话建立流程的具体实现进行说明。
实施例1：目标感知会话的类型为非成对协商类型。
例如，随意(Opportunistic)类型，单站雷达(Monostatic radar)类型或者被动(Passive)类型。
此情况下，该感知会话发起设备的MLME通知该感知会话发起设备的MAC子层为该类型的目 标感知会话所需资源，和/或该感知会话发起设备的MLME向该感知会话发送设备的SME发送第一指示信息，该第一指示信息用于指示该目标感知会话的建立结果，例如建立成功或失败。
在该实施例1中，感知会话发起设备可以是站点设备，例如，non-AP STA，或者，也可以是接入点设备。
在一些实施例中，该第一指示信息也可以通过MLME-SAP接口原语实现。记为MLME-SENSSETUP.confirm。

S302，感知会话发起设备的SME调用感知建立请求原语，指示该感知会话发起设备的MLME根据目标感知会话的类型，执行目标感知会话建立流程。
其中，感知建立请求原语可以用于指示待建立的目标感知会话的类型。
例如，若目标感知会话为非成对协商类型，该感知会话发起设备的MLME通知该感知会话发起设备的MAC子层为该类型的目标感知会话所需资源，和/或该感知会话发起设备的MLME向该感知会话发送设备的SME发送第一指示信息，该第一指示信息用于指示该目标感知会话的建立结果，例 如建立成功或失败。

以下，对所述第一请求帧和所述第一响应帧的帧格式设计进行说明。
应理解，图5至图8所示例的第一请求帧，所述第一响应帧的帧格式仅为示例，根据本申请示例的帧格式变换得到的其他帧格式均落入本申请的保护范围，本申请并不限于此。
在一些实施例中，所述第一请求帧通过动作帧(Action frame)或无确认动作帧(Action No Ack frame)实现。即测量建立请求帧可以通过Action frame或Action No Ack frame实现。
在一些实施例中，所述第一响应帧通过Action frame或Action No Ack frame实现。即测量建立响应帧可以通过Action frame或Action No Ack frame实现。
在一些实施例中，可以利用Action frame或Action No Ack frame中的至少一个字段指示该动作帧或无确认动作帧为测量建立请求帧或测量建立响应帧。
即所述第一请求帧和所述第一响应帧可以认为是感知动作帧。
在一些实施例中，所述Action frame或Action No Ack frame包括动作域字段，所述动作域字段包括动作类别(Category)字段、公共动作子类字段(Public Acton Field)和感知子类字段(SENS Subtype)，可以通过所述动作类别字段、所述公共动作子类字段和所述感知子类字段的取值联合指示该Action frame或Action No Ack frame为测量建立请求帧或测量建立响应帧。
作为示例，动作类别字段取值为4表示该帧为公共动作帧(Public Action frame)，公共动作子类字段为预留值(例如46～255范围内任意数值，以下，以46为例说明)表示该帧为感知动作帧，进一步通过感知子类的取值为指示该感知动作帧为测量建立请求帧或测量建立响应帧。
例如，感知子类的取值为第一值表示该感知动作帧为测量建立请求帧，感知子类的取值为第二值表示该感知动作帧为测量建立响应帧，其中，所述第一值和所述第二值不同。
作为示例，所述第一值为0，所述第二值为3。
图5是根据本申请一个实施例的测量建立请求帧的示意性帧格式图。在该帧格式中，动作类别字段取值为4表示该帧为公共动作帧(Public Action frame)，公共动作子类字段为46表示该帧为感知动作帧，感知子类取值为0指示该帧为测量建立请求帧。
在一些实施例中，如图5所示，所述测量建立请求帧还可以包括以下至少一个字段：
应理解，以下各个字段的含义和取值的对应关系仅为示例，只要保证每种含义对应唯一的取值即可，本申请并不限于此。
会话令牌(Dialog Token)字段：指示待建立的目标感知会话对应的会话标识。
感知参数字段，用于指示感知会话发起设备请求协商的感知会话参数。
在前述的情况1中，该会话令牌字段也可以用于指示测量建立的标识(Measurement Setup ID)。
感知建立命令(Setup Command)字段：用于指示采用强制方式建议等方式配置感知会话参数。
作为示例，取值为0表示强制(Demand)，取值为1表示建议(Suggest)。
重复次数(Number of Repetitions):用于指示测量的重复次数信息。
作为示例，取值为0表示无最大次数限制(此情况下，该测量只能被显式释放)，取值为1～255表示最大重复次数(此情况下，该测量可以被隐式释放，例如，达到最大重复次数后自动释放)。
另一种实施例为:该重复次数字段也可以替换为持续时间字段，用于指示测量的持续时间，或者，测量的结束时间。
作为示例，取值为0表示未设置结束时间(此情况下，该测量只能被显式释放)，取值为1～255指示以秒/分/时为单位的结束时间(此情况下，该测量可以被隐式释放，例如，达到所设置的结束时间后自动释放)。
该图5中的测量建立请求帧的帧格式可以适用于前述的情况1。
图6是根据本申请另一个实施例的测量建立请求帧的示意性帧格式图。在该帧格式中，动作类别字段取值为4表示该帧为公共动作帧(Public Action frame)，公共动作子类字段为46表示该帧为感知动作帧，感知子类取值为0指示该帧为测量建立请求帧。
与图5所示的测量建立请求帧的帧格式的区别在于，新增测量建立标识(Measurement Setup ID)字段指示测量建立标识。因此，该图6中的测量建立请求帧的帧格式可以适用于前述的情况2和情况3。
图7是根据本申请一个实施例的测量建立响应帧的示意性帧格式图。在该帧格式中，动作类别字段取值为4表示该帧为公共动作帧(Public Action frame)，公共动作子类字段为46表示该帧为感知动作帧，感知子类取值为3指示该帧为测量建立响应帧。
在一些实施例中，如图7所示，所述测量建立响应帧还可以包括以下至少一个字段：
会话令牌(Dialog Token)字段：指示测量建立的标识(Measurement Setup ID)。
在前述的情况1中，该会话令牌字段也可以用于指示测量建立的标识(Measurement Setup ID)。
测量信息字段，用于指示感知会话响应设备确定的感知会话参数。
该图7中的测量建立响应帧的帧格式可以适用于前述的情况1。
图8是根据本申请另一个实施例的测量建立响应帧的示意性帧格式图。在该帧格式中，动作类别字段取值为4表示该帧为公共动作帧(Public Action frame)，公共动作子类字段为46表示该帧为感知动作帧，感知子类取值为3指示该帧为测量建立响应帧。
与图7所示的测量建立响应帧的帧格式的区别在于，新增测量建立标识(Measurement Setup ID)字段指示测量建立标识。因此，该图8中的测量建立响应帧的帧格式可以适用于前述的情况2和情况3。
图9是根据本申请另一实施例的无线通信的方法400的示意性流程图，该方法400为结束感知会话的方法的示意性图。
如图9所示，该方法400包括如下内容：
S410，第一设备根据待结束的目标感知会话的类型，执行目标感知会话结束流程，其中，所述第一设备为感知会话发起设备或感知会话响应设备。
即感知会话结束流程可以是感知会话发起设备发起的，或者，也可以是感知会话响应设备发起的。
在一些实施例中，所述目标感知会话的类型可以为成对协商(Pairwise negotiation)类型，或者，也可以为非成对协商类型，例如随意(Opportunistic)类型，单站雷达(Monostatic radar)类型，或者，被动(Passive)类型。
应理解，本申请实施例可以适用于结束一个感知会话，或者，也可以适用于结束一个感知会话中的测量建立，因此，在一些实施例中，S410可以替换为：
感知会话发起设备根据待结束的测量建立对应的感知会话的类型，执行目标感知会话结束流程。
在一些实施例中，若所述目标感知会话为非成对协商类型，所述第一设备释放所述目标感知会话对应的目标资源。例如，释放为该目标感知会话分配的所有资源，比如存储资源或用于执行测量的资源等。

在一些实施例中，所述目标感知会话的结束流程可以是基于该第一设备的上层应用的指示，或称说，感知会话结束流程是上层应用触发的。例如，在需要结束目标感知会话时，第一设备的上层应用 可以调用SME提供的接口来发起感知会话结束流程，具体地，上层应用调用SME提供的接口，从而SME调用第三MLME-SAP接口原语来实现感知会话的结束。
在一些实施例中，所述上层应用可以指MAC层之上的应用，例如Wi-Fi驱动程序或者wpa_supplicant工具类应用等。
在一些实施例中，所述第三MLME-SAP接口原语或称感知结束请求原语或测量结束请求原语，记为MLME-SENSTEARDOWN.request。

测量建立标识列表(Measurement Setup ID list)字段:指示待释放的一个或多个测量建立的标识。
厂商自定义信息(VendorSpecificInfo)字段：指示厂商自定义信息。
在一些实施例中，该第一设备的SME在第三MLME SAP接收原语中将待结束的目标感知会话的信息指示给该第一设备的媒体访问控制子层管理实体(MAC sublayer management entity，MLME)后，该MLME可以根据该目标感知会话的类型，执行相应的感知会话结束流程。

在一些实施例中，所述Action frame或Action No Ack frame包括动作域字段，所述动作域字段包括动作类别(Category)字段、公共动作子类字段(Public Acton Field)和感知子类字段(SENS Subtype)，可以通过所述动作类别字段、所述公共动作子类字段和所述感知子类字段的取值联合指示该Action frame或Action No Ack frame为测量结束请求帧。
作为示例，动作类别字段取值为4表示该帧为公共动作帧(Public Action frame)，公共动作子类字段为预留值(例如46～255范围内任意数值，以下，以46为例说明)表示该帧为感知动作帧，进一步通过感知子类的取值为指示该动作帧为测量结束请求帧。
例如，感知子类的取值为第三值表示该动作帧为测量结束请求帧。作为示例，所述第三值为2。

图13是根据本申请另一个实施例的测量结束请求帧的示意性帧格式图。在该帧格式中，动作类别字段取值为4表示该帧为公共动作帧(Public Action frame)，公共动作子类字段为46表示该帧为感知动作帧，感知子类取值为2指示该帧为测量结束请求帧。
在一些实施例中，如图13所示，所述测量结束请求帧还可以包括以下至少一个字段：
会话令牌(Dialog Token)字段：指示待结束的目标感知会话对应的会话标识。

图14是根据本申请又一个实施例的测量结束请求帧的示意性帧格式图。在该帧格式中，动作类别字段取值为4表示该帧为公共动作帧(Public Action frame)，公共动作子类字段为46表示该帧为感知动作帧，感知子类取值为2指示该帧为测量结束请求帧。
在一些实施例中，如图14所示，所述测量结束请求帧还可以包括以下至少一个字段：
会话令牌(Dialog Token)字段：指示待结束的目标感知会话对应的会话标识。
测量建立数量(Number of Setups)字段：用于指示待结束的测量建立的数量信息。例如，取值为1～255表示要释放的建立的数量。可选的，取值为0表示释放所有建立的测量的资源。
测量建立标识列表(Measurement Setup ID list)字段:用于指示要释放的一个或多个测量建立的标识。可选地，测量建立数量取值为0时，该测量建立标识列表字段不存在。
在一些场景中，该图14中的测量建立请求帧的帧格式可以适用于前述的情况2-2和情况3-2。
