下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。
需要说明的是,本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。同时描述的“第一”、“第二”描述的对象可以相同,也可以不同。
本申请实施例的技术方案可以应用于各种通信系统,例如:无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)或其他通信系统等。
示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括接入点(Access Point,AP)110,以及通过接入点110接入网络的站点(STATION,STA)120。
在一些场景中,AP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)。
通信系统100中的通信可以是AP与non-AP STA之间的通信,也可以是non-AP STA与non-AP STA之间的通信,或者STA和peer STA之间的通信,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。
在一些实施例中,non-AP STA可以支持802.11be制式。non-AP STA也可以支持802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等多种当前以及未来的802.11家族的无线局域网(wireless local area networks,WLAN)制式。
在一些实施例中,AP可以为支持802.11be制式的设备。AP也可以为支持802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等多种当前以及未来的802.11家族的WLAN制式的设备。
在本申请实施例中,STA可以是支持WLAN/WiFi技术的手机(Mobile Phone)、平板电脑(Pad)、电脑、虚拟现实(Virtual Reality,VR)设备、增强现实(Augmented Reality,AR)设备、工业控制(industrial control)中的无线设备、机顶盒、无人驾驶(self driving)中的无线设备、车载通信设备、远程医疗(remote medical)中的无线设备、智能电网(smart grid)中的无线设备、运输安全(transportation safety)中的无线设备、智慧城市(smart city)中的无线设备或智慧家庭(smart home)中的无线设备、无线通信芯片/ASIC/SOC/等。
WLAN技术可支持频段可以包括但不限于:低频段(例如2.4GHz、5GHz、6GHz)、高频段(例如60GHz)。
图1示例性地示出了一个AP STA和两个non-AP STA,在一些实施方式中,该通信系统100可以包括多个AP STA以及包括其它数量的non-AP STA,本申请实施例对此不做限定。
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。
应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。
在本申请实施例的描述中,术语“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。
为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,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。
感知发起设备(Sensing Initiator)可以发起1个WLAN感知步骤(WLAN sensing procedure),主要包含以下步骤中的1个或多个:感知会话设置(sensing session setup),感知测量设置(sensing measurement setup),感知测量实例(sensing measurement instance),感知测量设置终止(sensing measurement setup termination)和感知会话终止(sensing session termination)。
其中感知会话(sensing session)是1个感知发起设备(Sensing Initiator)与1个感知响应设备(Sensing responder)之间建立的,即在不考虑点对点点(P2P,Point to Point)Sensing的情况下,AP与1个STA建立1个sensing session,使用MAC地址和/或AID/UID来标记1个具体地sensing session;
1个感知发起设备(Sensing Initiator)与1个感知响应设备(Sensing responder)之间可能建立多个感知测量实例(sensing measurement实例),每个sensing measurement实例可以使用测量设置标识(Measurement Setup ID)来标记。
针对感知测量设置和终止机制,本申请实施例提出了不同的改变感知发起设备和感知响应设备角色的方式,并提出了不同角色发起感知测量设置终止的方式。
本申请实施例提出一种通信方法,图2是根据本申请实施例的一种通信方法200的示意性流程图,该方法可以应用于图1所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S210:第一设备发送第一信息帧,该第一信息帧用于分配第一测量设置标识。
本申请实施例,通过第一设备发送的第一信息帧来分配第一测量设置标识,提供了明确的测量设置标识分配方案。
具体地,上述第一测量设置标识可以是一种Measurement Setup ID,第一设备发送用于分配Measurement Setup ID的第一信息帧的过程,也可以称为第一设备进行Measurement Setup ID分配的过程,还可以称为第一设备进行感知测量设置的过程等。
上述第一设备发送的第一信息帧可以为感知测量设置请求帧(Sensing Measurement Setup Request frame),也可以为感知测量设置响应帧(Sensing Measurement Setup Response frame),第一设备可以在感知测量设置请求帧或感知测量设置响应帧中携带其分配的测量设置标识(Measurement Setup ID)。
发送感知测量设置请求帧的设备可以称为感知发起设备,感知发起设备可以接收对端(即感知响应设备)发送的感知测量设置响应帧。感知发起设备可以在感知测量设置请求帧中其携带分配的测量设置标识,相应地,该感知发起设备接收的感知测量设置响应帧中,可以不携带测量设置标识;也就是说,这种情况下感知发起设备作为分配测量设置标识的设备。或者,感知发起设备可以在感 知测量设置请求帧中不携带测量设置标识,相应地,该感知发起设备接收的感知测量设置响应帧中可以携带感知响应设备所分配的测量设置标识;也就是说,这种情况下感知响应设备作为分配测量设置标识的设备。
以AP设备和STA设备之间建立感知为例。例如,STA可以向AP发送感知测量设置请求帧,并在该感知测量设置请求帧中携带STA分配的测量设置标识;AP向STA反馈感知测量设置响应帧,该感知测量设置响应帧中不携带测量设置标识。又如,STA可以向AP发送感知测量设置请求帧,该感知测量设置请求帧中不携带测量设置标识;AP向STA反馈感知测量设置响应帧,并在该感知测量设置响应帧中携带AP分配的测量设置标识。又如,AP可以向STA发送感知测量设置请求帧,并在该感知测量设置请求帧中携带AP分配的测量设置标识;STA向AP反馈感知测量设置响应帧,该感知测量设置响应帧中不携带测量设置标识。以上情况仅为举例,本申请不排除其他场景。
例如,第一设备向第二设备发送感知测量设置请求帧(也可称为第一信息帧),在感知测量设置请求帧中携带第一设备分配的测量设置标识;第一设备从第二设备接收感知测量设置响应帧(也可称为第二信息帧),感知测量设置响应帧中不携带测量设置标识。第一设备的角色为感知发起设备,第二设备的角色为感知响应设备。其中,第一设备可以为AP,第二设备可以为STA;或者,第一设备可以为STA,第二设备可以为AP。
又如,第一设备从第二设备接收感知测量设置请求帧(也可称为第二信息帧),该感知测量设置请求帧中不携带测量设置标识;第一设备向第二设备发送感知测量设置响应帧(也可称为第一信息帧),感知测量设置响应帧中携带第二设备分配的测量设置标识。第一设备的角色为感知响应设备,第二设备的角色为感知发起设备。其中,第一设备可以为AP,第二设备可以为STA;或者,第一设备可以为STA,第二设备可以为AP。
在上述示例中,第一设备的角色和/或第二设备的角色可以在感知测量设置阶段确定。相应地,第一设备的角色和/或第二设备的角色在单个感知会话中可变。
或者,第一设备的角色和/或第二设备的角色在感知会话设置阶段确定。相应地,第一设备的角色和/或第二设备的角色在单个感知会话中不可变。
图3A和图3B分别对应根据单个感知会话中设备的角色(包括感知发起设备和感知响应设备)是否可变,测量设置标识分配的两种实现方式。
在图3A中,感知发起设备(Sensing Initiator)和感知响应设备(Sensing Responder)角色在感知测量设置(Sensing Measurement Setup)时确定。
具体地,感知会话设置(Sensing Session Setup)时不确定感知发起设备和感知响应设备的角色,感知发起设备和感知响应设备的角色在Sensing Measurement Setup时确定,那么Sensing Initiator和Sensing Responder的角色在单个感知会话(Sensing Session)中是可变的。
在图3A中,Sensing Session Setup是成对的(基于Pairwise的),本实施例涉及的Sensing Session是AP与单个STA之间成对建立的。图3A中以AP分别与STA 1、STA 2以及STA 3进行Sensing Session Setup为例,介绍Measurement Setup ID设置与感知发起设备之间的联系,包括以下步骤:
1)第一设备(具体如AP)作为感知发起设备与第二设备(如STA 1和STA 2)进行Measurement Setup ID=1的设置,STA 1和STA 2作为感知响应设备;
2)第一设备(如AP)作为感知发起设备与第二设备(如STA 1和STA 2)进行Measurement Setup ID=2的设置,STA 1和STA 2作为感知响应设备;
3)第一设备(具体如STA 1)作为感知发起设备与AP进行Measurement Setup ID=x的设置,第二设备(如AP)作为感知响应设备。可以看出,在本步骤中,AP和STA 1的角色发生了改变,AP由原来的感知发起设备改变为感知响应设备,STA 1由原来的感知响应设备改变为感知发起设备。
由于Measurement Setup ID=1和Measurement Setup ID=2中均有STA 1,因此STA 1可以将x设置为3,避免Measurement Setup ID冲突。
4)第一设备(具体如STA 2)作为感知发起设备与AP进行Measurement Setup ID=y的设置,第二设备(如AP)作为感知响应设备。可以看出,在本步骤中,STA 2的角色发生了改变,由原来的感知响应设备改变为感知发起设备。
由于Measurement Setup ID=3是STA 1与AP之间单独建立的,所以STA 2并不知道Measurement Setup ID=3是否可用,如果STA 2将y设置为3,就会发生Measurement Setup ID冲突。为了解决Measurement Setup ID冲突的问题,AP可以采用STA 2分配的Measurement Setup ID=3、以及STA 2的信息来唯一标识该Measurement Setup;其中,STA 2的信息可以包括STA 2的 MAC地址、关联的标识符(AID,Association Identifier)和未关联的标识符(UID,Unassociation Identifier)中的至少一项。关于Measurement Setup ID冲突的问题,本申请还提出其他的冲突解决方案,后续将进一步介绍。
5)如果STA 1不参与感知测量(Sensing Measurement),那么STA 1可以请求AP作为其代理与其他的STA进行感知测量。例如,STA 1作为感知代理(SBP,Sensing By Proxy)请求(requesting)STA,向AP发送SBP请求帧,请求AP与STA 3进行感知测量。此时,AP作为感知发起设备与STA 3进行Measurement Setup ID的设置,STA 3作为感知响应设备。在本步骤中,Measurement Setup ID由AP设置;由于所有的Measurement Setup ID均在AP与另一端之间设置(也就是AP知晓已经存在的Measurement Setup ID),因此AP在当前设置Measurement Setup ID时能够避开已经存在的Measurement Setup ID,从而避免Measurement Setup ID发生冲突。例如,在本示例中,AP设置Measurement Setup ID=5。这种情况下,AP即为上述第一设备。
6)如果STA2不参与感知测量(Sensing Measurement),那么STA 2可以请求AP作为其代理与其他的STA进行感知测量。例如,STA 2作为SBP requesting STA,向AP发送SBP请求帧,请求AP与STA 3进行感知测量。此时,AP作为感知发起设备与STA 3进行Measurement Setup ID的设置,STA 3作为感知响应设备。基于与上述步骤5)中同样的原因,AP在设置时能够避免Measurement Setup ID发生冲突。例如,在本示例中,AP设置Measurement Setup ID=6。这种情况下,AP即为上述第一设备。
需要强调的是,上述步骤1)至步骤6)中的编号仅用于方便说明,并不用于限制步骤之间的时间顺序。
值得注意的是,在图3A所示的方案中,由于感知发起设备的角色在感知会话中根据不同的Sensing Measurement ID可以发生变化,因此基于触发的(TB,Trigger Based)会话和非基于触发的(non-TB)会话可以同时存在于同一个感知会话中。
在图3B中,感知发起设备(Sensing Initiator)和感知响应设备(Sensing Responder)角色在感知会话设置(Sensing Session Setup)时确定。
具体地,感知发起设备和感知响应设备的角色在Sensing Session Setup时确定,感知发起设备和感知响应设备的角色在感知测量设置(Sensing Measurement Setup)时不可变。如果需要改变角色,需要先终止已经建立的相关感知会话,再重新建立新的感知会话。
例如,第一设备的角色和/或第二设备的角色在感知会话设置阶段确定,包括:
在初始感知会话被终止且当前感知会话被建立的情况下,第一设备的角色和/或第二设备的角色在当前感知会话的感知会话设置阶段确定;其中,初始感知会话为所述当前感知会话之前的感知会话。
具体地,例如,在初始感知会话中,第一设备的角色为感知响应设备,第二设备的角色为感知发起设备;在终止初始感知会话、并建立当前感知会话时,重新确定或改变第一设备的角色和/或第二设备的角色(如将第一设备的角色改变为感知发起设备,将第二设备的角色改变为感知响应设备)。又如,在初始感知会话中,第一设备的角色为感知发起设备,第二设备的角色为感知响应设备;在终止初始感知会话、并建立当前感知会话时,重新确定或改变第一设备的角色和/或第二设备的角色(如将第一设备的角色改变为感知响应设备,将第二设备的角色改变为感知发起设备)。其中,上述第一设备可以为AP,第二设备可以为STA;或者,第一设备可以为STA,第二设备可以为AP。
在图3B中,Sensing Session Setup是成对的(基于Pairwise的),本实施例涉及的Sensing Session是AP与单个STA之间成对建立的。图3A中以AP分别与STA 1、STA 2以及STA 3进行Sensing Session Setup为例,介绍Measurement Setup ID设置与感知发起设备之间的联系,包括以下步骤:
1)AP与STA 1,STA 2和STA 3在Sensing Session Setup建立时,确定设备的角色,设定Sensing Initiator=AP。
2)第一设备(具体如AP)作为感知发起设备与第二设备(如STA 1和STA 2)进行Measurement Setup ID=1的设置,STA 1和STA 2作为感知响应设备。
3)第一设备(具体如AP)作为感知发起设备与第二设备(如STA 1和STA 2)进行Measurement Setup ID=2的设置,STA 1和STA 2作为感知响应设备。
4)如果希望改变设备的角色,把STA 1设置为感知发起设备,需要先终止AP与STA 1之间已经建立的感知会话(Sensing Session),然后AP与STA 1之间重新进行感知会话设置(Sensing Session Setup),设定Sensing Initiator=STA 1;STA 1作为感知发起设备与AP进行Measurement  Setup ID=x的设置,AP作为感知响应设备。这种情况下,上述STA 1即为上述第一设备,由STA1进行与AP之间的感知会话设置。
由于Measurement Setup ID=1和Measurement Setup ID=2中均有STA 1,因此STA 1可以将x设置为3,避免Measurement Setup ID冲突。
5)如果希望改变设备的角色,把STA 2设置为感知发起设备,需要先终止AP与STA 2之间已经建立的感知会话,然后AP与STA 2之间重新进行感知会话设置,设定Sensing Initiator=STA2;STA 2作为感知发起设备与AP进行Measurement Setup ID=y的设置,AP作为感知响应设备。这种情况下,上述STA 2即为上述第一设备,由STA 2进行与AP之间的感知会话设置。
由于Measurement Setup ID=3是STA 1与AP之间单独建立的,所以STA 2并不知道Measurement Setup ID=3是不是可用,如果STA 2将y设置为3,就会发生Measurement Setup ID冲突。为了解决Measurement Setup ID冲突的问题,AP可以采用STA 2分配的Measurement Setup ID=3、以及STA 2的信息来唯一标识该Measurement Setup;其中,STA 2的信息可以包括STA 2的MAC地址、AID和UID中的至少一项。关于Measurement Setup ID冲突的问题,本申请还提出其他的冲突解决方案,后续将进一步介绍。
6)如果STA 1不参与感知测量(Sensing Measurement),那么STA 1可以请求AP作为其代理与其他的STA进行感知测量。例如,STA 1作为感知代理(SBP,Sensing By Proxy)请求(requesting)STA,向AP发送SBP请求帧,请求AP与STA 3进行感知测量。此时,AP作为感知发起设备与STA 3进行Measurement Setup ID的设置,STA 3作为感知响应设备。在本步骤中,Measurement Setup ID由AP设置;由于所有的Measurement Setup ID均在AP与另一端之间设置(也就是AP知晓已经存在的Measurement Setup ID),因此AP在当前设置Measurement Setup ID时能够避开已经存在的Measurement Setup ID,从而避免Measurement Setup ID发生冲突。例如,在本示例中,AP设置Measurement Setup ID=5。这种情况下,AP即为上述第一设备。
7)如果STA2不参与感知测量(Sensing Measurement),那么STA 2可以请求AP作为其代理与其他的STA进行感知测量。例如,STA 2作为SBP requesting STA,向AP发送SBP请求帧,请求AP与STA 3进行感知测量。此时,AP作为感知发起设备与STA 3进行Measurement Setup ID的设置,STA 3作为感知响应设备。基于与上述步骤5)中同样的原因,AP在设置时能够避免Measurement Setup ID发生冲突。例如,在本示例中,AP设置Measurement Setup ID=6。这种情况下,AP即为上述第一设备。
需要强调的是,上述步骤1)至步骤7)中的编号仅用于方便说明,并不用于限制步骤之间的时间顺序。
值得注意的是,在图3B所示的方案中,由于感知发起设备的角色在一个感知会话中不可更改,因此基于触发的(TB,Trigger Based)会话和非基于触发的(non-TB)会话不可以同时存在于同一个感知会话中。
前述内容参照图3A和3B介绍了感知发起设备与感知响应设备之间进行Sensing Measurement Setup(分配Measurement Setup ID)的方式,针对在同一个感知会话中感知发起设备与感知响应设备角色是否可变,分别介绍了两种不同的方式。其中涉及到Measurement Setup ID冲突的问题,针对该问题,以下详细介绍。
例如,如果由AP分配测量设置标识,则接收第一测量设置标识的第二设备可以采用该第一测量设置标识来唯一标识该测量设置。进一步地,如果测量设置标识还可以由STA分配,则接收第一测量设置标识的第二设备可以采用该第一测量设置标识、以及第一设备的信息来唯一标识该测量设置。其中,第一设备的信息可以包括第一设备的MAC地址/AID/UID。
举例一:
在可以由AP或STA分配测量设置标识的情况下(也就是不限制分配测量设置标识的主体),如果由第一设备向第二设备发送用于分配测量设置标识的第一信息帧,则该第一测量设置标识及第一设备的信息可以用于供第二设备唯一标识该测量设置;其中,
第二设备包括接收该第一信息帧的设备;
第一设备的信息包括第一设备的MAC地址、AID和UID中的至少一项。第一设备的信息可以携带在上述第一信息帧中,如在第一信息帧的用于携带第一设备的MAC地址的字段和/或用于携带第一设备的AID和/或UID的字段中携带。
例如,使用<Initiator MAC地址/AID/UID,Measurement Setup ID>元组来标记1个measurement setup。
对于感知发起设备来说,其分配的Measurement Setup ID自身是可以分辨的;但是对于感知响应设备来说,当不同的感知发起设备分配的Measurement Setup ID出现重复时,感知响应设备需要区分重复的这些Measurement Setup ID具体对应的是哪个感知发起设备分配的。因此,可以将感知发起设备的MAC地址/AID/UID和该感知发起设备所分配的Measurement Setup ID结合形成<Initiator MAC地址/AID/UID,Measurement Setup ID>元组,来标记1个具体的Measurement Setup;对于感知发起设备来说就不会出现Measurement Setup ID重复无法分辨的问题,因此可以采用其分配的Measurement Setup ID来标记该Measurement Setup。
例如,对于图2A步骤3)中STA 1建立的Measurement Setup ID值为x标识的Measurement Setup,AP使用<AID=1,Measurement Setup ID=x>元组来唯一标识。STA 1的AID=1。
又如,对于图2A步骤4)中STA 2建立的Measurement Setup ID值为y标识的Measurement Setup,AP使用<AID=2,Measurement Setup ID=y>元组来唯一标识。STA 2的AID=2。
可见,即使x=y,AP也可以分辨出STA 1与STA 2所分配的Measurement Setup ID,从而避免了Measurement Setup ID冲突。
举例二:
在仅可以由AP分配测量设置标识的情况下,如果由第一设备向第二设备发送用于分配测量设置标识的第一信息帧,则该第一测量设置标识用于供第二设备唯一标识该测量设置。
例如,如果限制Measurement Setup ID始终由AP来分配,AP可以将与STA 1之间的Measurement Setup的Measurement Setup ID和与STA 2之间的Measurement Setup的Measurement Setup ID设置为不同值,从而避免Measurement Setup ID冲突,例如将前述两个Measurement Setup ID分别设置为x=3,y=4。
由上述两种方式可见,如果Measurement Setup ID始终由AP来分配,则两端设备都可以仅通过Measurement Setup ID来分辨Measurement Setup;如果Measurement Setup ID可以由AP或STA分配,则分配Measurement Setup ID的设备可以仅通过Measurement Setup ID来分辨Measurement Setup,对端设备则需要通过Measurement Setup ID和分配设备的信息所构成的元组来分辨Measurement Setup。
以下介绍上述感知测量设置请求帧(Measurement Setup Request frame)和感知测量设置响应帧(Sensing Measurement Setup Response frame)的帧结构,以及采用该感知测量设置请求帧和感知测量设置响应帧分配测量设置标识的具体实施方式。
图4A是根据本申请实施例的一种感知测量设置请求帧的帧结构示意图。
在一些实施方式中,感知测量设置请求帧包括第一指示字段和/或第一测量设置标识字段;其中,
第一指示字段,用于指示该感知测量设置请求帧中是否包含第一测量设置标识字段;
第一测量设置标识字段,用于携带第一测量设置标识。
上述第一指示字段可以为图4A中的是否存在测量设置标识子域(Measurement Setup ID Present subfield),上述测量设置标识字段可以为图4A中的测量设置标识子域(Measurement Setup ID subfield)。Measurement Setup ID Present subfield用于指示Measurement Setup ID subfield是否存在,例如,Measurement Setup ID Present=0代表Sensing Measurement Setup Request frame帧中不存在Measurement Setup ID subfield;Measurement Setup ID Present=1代表Sensing Measurement Setup Request frame帧中存在Measurement Setup ID subfield。Measurement Setup ID subfield中携带测量设置标识。
如果感知发起设备分配了感知测量设置,则其发送的感知测量设置请求帧中包括Measurement Setup ID subfield,且Measurement Setup ID subfield中携带该感知发起设备所分配的Measurement Setup ID。如果感知发起设备没有分配感知测量设置,则其发送的感知测量设置请求帧中不包括Measurement Setup ID subfield。
进一步地,感知测量设置请求帧中还可以包括用于指示是否允许感知响应设备发起感知测量设置终止的字段,如图4A中的是否允许响应设备发起感知测量设置终止子域(Sensing Measurement Setup Termination from Responder subfield)。例如,Sensing Measurement Setup Termination from Responder=1,代表允许感知响应设备发起感知测量设置终止;Sensing Measurement Setup Termination from Responder=0,代表不允许感知响应设备发起感知测量设置终止。后续感知测量设置终止过程中,感知响应设备可以根据该设置发起/不发起感知设置终止过程。
如图4A所示,上述Measurement Setup ID Present subfield和Sensing Measurement Setup  Termination from Responder subfield可以包含在感知测量设置请求帧中的控制域中。
如果4A所示,上述Measurement Setup ID Present subfield及Sensing Measurement Setup Termination from Responder subfield的长度可以分别为1比特,Measurement Setup ID subfield的长度可以为8比特或0比特。
进一步地,感知测量设置请求帧中还包含用于携带发送该帧的设备(如上述第一设备)的MAC地址的字段,例如MAC地址字段,该MAC地址字段可以在感知测量设置请求帧的MAC帧头中,例如图4A所示的MAC帧头中的地址1/地址2/地址3为上述MAC地址字段。
图4B是根据本申请实施例的另一种感知测量设置请求帧的帧结构示意图。图4B所示的感知测量设置请求帧中可以包含用于携带发送该帧的设备(如上述第一设备)的AID和/或UID的字段,如图4B所示的AID/UID域(AID/UID filed)。如果感知测量设置请求帧由STA发送,其可以显示地包含1个AID/UID filed用于指示STA的AID/UID;收到该感知测量设置请求帧的AP可以结合该Measurement Setup ID和该STA的AID/UID共同来标记1个Measurement Setup(ID),从而避免不同的STA作为感知发起设备分配的Measurement Setup ID发生冲突。如图4B所示,AID/UID filed可以包含在感知测量设置请求帧的动作域中,其长度可以为2个字节。图4B所示的感知测量设置请求帧的其他结构与图4A所示相同,在此不再赘述。
图5是根据本申请实施例的一种感知测量设置响应帧的帧结构示意图。
在一些实施方式中,感知测量设置响应帧包括第三指示字段和/或第三测量设置标识字段;其中,
第三指示字段,用于指示该感知测量设置响应帧中是否包含该第三测量设置标识字段;
第三测量设置标识字段,用于携带第一测量设置标识。
在一些实施方式中,上述感知测量设置响应帧可以包括响应控制字段,该响应控制字段中包括上述第三指示字段。
上述第一指示字段可以为图5中的是否存在测量设置标识子域(Measurement Setup ID Present subfield),上述测量设置标识字段可以为图5中的测量设置标识域(Measurement Setup ID field)。Measurement Setup ID Present subfield用于指示Measurement Setup ID field是否存在,例如,Measurement Setup ID Present=0代表Sensing Measurement Setup Request frame帧中不存在Measurement Setup ID field;Measurement Setup ID Present=1代表Sensing Measurement Setup Request frame帧中存在Measurement Setup ID field。Measurement Setup ID field中携带测量设置标识。
如果感知响应设备分配了感知测量设置,则其发送的感知测量设置响应帧中包括Measurement Setup ID field,且Measurement Setup ID field中携带该感知响应设备所分配的Measurement Setup ID。如果感知响应设备没有分配感知测量设置,则其发送的感知测量设置响应帧中不包括Measurement Setup ID field。
如图5所示,上述Measurement Setup ID Present subfield可以包含在感知测量设置响应帧的响应控制域(Response Control field)中。
如图5所示,上述Measurement Setup ID Present subfield的长度可以为1比特;Response Control field的长度可以为1个字节,包括Measurement Setup ID Present subfield和7个比特的保留子域(Reserved);Measurement Setup ID field的长度可以为1字节或0字节。
结合上述感知测量设置请求帧和感知测量设置响应帧,以下举几个具体示例。
示例1:
如图6A和6B分别显示了示例1的两种实现方式。
AP作为感知发起设备进行感知测量设置,AP发送感知测量设置请求帧,其中的Measurement Setup ID Present subfield置为1,并在Measurement Setup ID subfield中携带AP分配的Measurement Setup ID(如分配Measurement Setup ID=m)。
STA作为感知响应设备,收到感知测量设置请求帧后,回复感知测量设置响应帧,其中的Measurement Setup ID Present subfield置为0。
以图6A为例,如果采用上述第一种Measurement Setup ID冲突解决方式,即在可以由AP或STA分配测量设置标识的情况下,STA可以通过AP分配的Measurement Setup ID及AP的MAC地址/AID/UID来唯一标识该测量设置。例如,STA通过<AID=0,Measurement Setup ID=m>元组来唯一标识该测量设置,其中AID=0为STA的AID。
以图6B为例,如果采用上述第二种Measurement Setup ID冲突解决方式,即始终由AP分配测 量设置标识,则AP在分配时就能够保证不发生Measurement Setup ID冲突,因此STA可以通过AP分配的Measurement Setup ID值m来唯一标识该Measurement Setup。
示例2.1:
如图6C显示了示例2.1的实现方式。
STA作为感知发起设备进行感知测量设置,STA发送感知测量设置请求帧,其中的Measurement Setup ID Present subfield置为1,并在Measurement Setup ID subfield中携带STA分配的Measurement Setup ID。
AP作为感知响应设备,收到感知测量设置请求帧后,需要结合STA的MAC地址/AID/UID组成<initiator MAC Address/AID/UID,Measurement Setup ID>来标记1个具体的测量设置。
AP回复感知测量设置响应帧,其中的Measurement Setup ID Present subfield置为0。
示例2.1中,采用了上述第一种Measurement Setup ID冲突解决方式,即在可以由AP或STA分配测量设置标识的情况下,AP可以通过STA分配的Measurement Setup ID及STA的MAC地址/AID/UID来唯一标识该测量设置。
示例2.2:
如图6D显示了示例2.2的实现方式。
STA作为感知发起设备,STA发送感知测量设置请求帧,其中的Measurement Setup ID Present subfield置为0,那么感知测量设置请求帧中不携带Measurement Setup ID,表明Measurement Setup ID由AP分配。
AP作为感知响应设备,收到感知测量设置请求帧后,AP回复感知测量设置响应帧,其中的Measurement Setup ID Present subfield置为,并在Measurement Setup ID field中携带AP分配的Measurement Setup ID。
示例2.2中,采用了上述第二种Measurement Setup ID冲突解决方式,即始终由AP分配测量设置标识。
在一些实施方式中,可以由STA向AP发送SBP请求帧(SBP Request frame),用于请求AP作为该STA的代理与感知响应设备进行感知测量。SBP请求帧由STA发送,接收者为AP,目的请求AP作为感知代理(sensing proxy)为其进行无线局域网感知(WLAN Sensing,Wireless Local Area Network Sensing)。发送该SBP请求帧的STA不参与感知测量,AP为感知发起设备,其它参与感知测量的STA(s)为感知响应设备。
例如,上述第一设备在发送感知测量设置请求帧之前,可以包括:
第一设备从第一STA接收第二信息帧,该第二信息帧用于请求第一设备作为第一STA的代理进行感知测量。其中,第一设备可以为AP设备,第二信息帧可以SBP请求帧。
SBP请求帧包括以下至少一项:
测量实例周期字段,用于携带请求第一设备代理感知时的测量周期;
测量实例持续时间字段,用于携带请求所述第一设备代理感知时的测量时长;
基于CSI的测量结果字段,用于指示请求所述第一设备代理感知时所需要的感知测量结果类型是否为CSI信息;
基于波束SNR的测量结果字段,用于指示请求所述第一设备代理感知时所需要的感知测量结果类型是否为波束SNR信息;
响应设备数量字段,用于指示参与测量设置并进行感知测量的感知响应设备的数量;
是否存在响应设备信息列表字段,用于指示所述SBP请求帧中是否包含响应设备信息列表;
响应设备信息列表字段,用于携带一个或多个感知响应设备的信息。
图7是根据本申请实施例的一种SBP请求帧结构示意图,如图7所示:
上述测量实例周期字段可以为Measurement Instance Period subfeild,用于指示请求AP代理感知时的测量周期。
上述测量实例持续时间字段可以为Measurement Instance Duration subfeild,用于指示请求AP代理会话时的测量时长。
上述基于CSI的测量结果字段可以为CSI Based Result subfeild,用于指示请求AP代理会话时所需要的感知测量结果类型(Sensing Measurement Result Type)是否为CSI信息。例如,CSI Based Result subfeild长度可以为1个比特,取值为1时代表请求测量的结果是基于CSI的,取值为0时代表请求测量的结果不是基于CSI的;或者,取值为0时代表请求测量的结果是基于CSI的,取值为1时代表请求测量的结果不是基于CSI的。
上述基于波束SNR的测量结果字段可以为Beam SNR Based Result subfeild,用于指示请求AP代理会话时所需要的感知测量结果类型是否Beam SNR信息。例如,Beam SNR Based Result subfeild长度可以为1个比特,取值为1时代表请求测量的结果是基于Beam SNR信息的,取值为0时代表请求测量的结果不是基于Beam SNR信息的;或者,取值为0时代表请求测量的结果是基于Beam SNR信息的,取值为1时代表请求测量的结果不是基于Beam SNR信息的。
上述响应设备数量字段可以为Number of Responders field,用于指示有多少个感知响应设备参与测量设置并进行感知测量。
上述是否存在响应设备信息列表字段可以为Responder Info List Present subfeild,用于指示SBP请求帧中是否包含响应设备信息列表字段(如图7中的Responder Info List field)。例如,Responder Info List Present=1代表SBP请求帧中包含Responder Info List field,Responder Info List Present=0代表SBP请求帧中不包含Responder Info List field;或者,Responder Info List Present=0代表SBP请求帧中包含Responder Info List field,Responder Info List Present=1代表SBP请求帧中不包含Responder Info List field。
上述响应设备信息列表字段可以为Responder Info List field;例如,当当Responder Info List Present=1时,Responder Info List field包含1个或多个感知响应设备的AID/UID子域(Responder AID/UID subfields);且Responder AID/UID subfields的数目由Number of Responders指示。
值得注意的是,在STA只指示AP需要多少个感知响应设备参与感知测量的情况下,Number of Responders指示感知响应设备的数量,Responder Info List不存在。在STA指示AP具体需要哪些感知响应设备参与感知测量的情况下,Number of Responders指示Sensing Responders数量,且Responder Info List指示各个感知响应设备的标识符。
如图7所示,SBP请求帧可以包括MAC帧头和MAC帧体。其中,MAC帧头可以包括帧控制字段、时长字段、地址1字段、地址2字段、地址3字段、序列控制字段、高吞吐控制字段。MAC帧体可以包括动作域字段、多个元素字段和帧校验字段。其中,动作域字段可以包括动作类别域(长度可以为1字节,取值可以为4)、公共动作子类域(长度可以为1字节,取值可以为46)、会话令牌域(长度可以为1字节)、感知子类域(长度可以为1字节,取值可以为2)、感知测量设置命令域(长度可以为1字节)、会话(SENS)参数(SENS Parameters)域(长度可以为3字节)、响应设备数量域(长度可以为1字节)、是否存在响应设备信息列表域(长度可以为1字节)、响应设备信息列表域(长度可变)。其中,SENS参数域可以包括上述Measurement Instance Period subfeild(长度可以为16比特)、Measurement Instance Duration subfeild(长度可以为4比特)、CSI Based Result subfeild(长度可以为1比特)、Beam SNR Based Result subfeild(长度可以为1比特)和保留子域(长度可以为2比特)。
以上实施例实现了在不同阶段(感知会话设置时/感知测量设置时)改变Sensing Initiator和Sensing Responder角色的方法。并且,针对non-AP STA作为感知发起设备分配Measurement Setup ID可能造成的Measurement Setup ID冲突的问题,提出了两种冲突解决方案,包括采用<initiator MAC地址/AID/UID,Measurement Setup ID>标记具体的测量设置或者测量设置标识的方式,以及始终由AP分配Measurement Setup ID的方式。
本申请实施例还提出一种通信方法,用于实现终止感知测量设置,本申请实施例提出了不同角色发起感知测量设置终止(Sensing Measurement Setup Termination)的方案并设计了相关的限制规则,使得感知测量设置终止方式更加灵活且合理。以下参照附图详细介绍。
图8是根据本申请实施例的一种通信方法800实现流程图,包括:
S810:第三设备发送第三信息帧,该第三信息帧用于指示终止/拒绝终止感知测量设置。
在一些实施方式中,上述第三信息帧包括感知测量设置终止帧(Sensing Measurement Setup Termination)。
上述S810之前还可以包括:第三设备接收第四信息帧,该第四信息帧用于请求终止感知测量设置。
在一些实施方式中,上述第四信息帧包括感知测量设置终止请求帧(Sensing Measurement Setup Termination Request)。
按照发起感知测量设置终止的角色不同以及是否允许感知响应设备发起感知测量设置终止请求,分为以下几种方案:
方案1:感知发起设备发起感知测量设置终止。
在本方案中,感知发起设备向感知响应设备发送感知测量设置终止帧,无须感知响应设备同意 即可终止相关Sensing Measurement Setup。
如9A所示,如果定义感知测量设置终止帧为需要确认的帧类型(Action),那么感知响应设备可以发送Ack帧确认,以确认感知发起设备发起的感知测量设置终止(Sensing Measurement Setup Termination)。
如图9B所示,如果定义感知测量设置终止帧为不需要确认的帧类型(Action No Ack),那么感知响应设备不发送任何帧,默认执行Sensing Measurement Setup Termination。
感知发起设备发送的感知测量设置终止帧可以携带终止感知测量设置的原因,以利于感知响应设备下一步进行通信/感知调度。
方案2:感知响应设备发起感知测量设置终止。
方案2分为两种方式,第一种方式为默认感知响应设备可以发起终止感知测量设置的请求,但仍由感知发起设备决定是否终止感知测量设置。第二种方式为感知响应设备按照指示来发起终止感知测量设置的请求。以下分别介绍上述两种方式:
方案2的方式一:
在该方式下,默认感知响应设备可以发起终止感知测量设置的请求,但仍由感知发起设备决定是否终止感知测量设置。
如图10A所示,感知响应设备发送感知测量设置终止请求帧,主动请求终止感知测量设置,感知响应设备回复感知测量设置终止帧,处理该请求,如终止(也就是接受终止请求),或者拒绝终止(也就是拒绝终止请求)。
其中感知测量设置终止请求帧的帧类型优选为Action No Ack帧类型,但本申请对此不做限制。
感知响应设备发送的感知测量设置终止请求帧可以携带终止感知测量设置的原因,感知发起设备回复的感知测量设置终止帧也可以指示接受/拒绝终止感知测量设置。
方案2的方式二:
感知响应设备按指示决定是否发起感知测量设置终止请求。
在上述介绍感知测量设置的实施方式中,介绍了感知发起设备和感知响应设备进行感知测量设置时,明确指示是否允许感知响应设备发起感知测量设置终止请求。
例如,通过在感知测量设置请求帧(Sensing Measurement Setup Request frame)中包含用于指示是否允许感知响应设备发起感知测量设置终止的字段(如Sensing Measurement Setup Termination from Responder subfield)。例如,如果Sensing Measurement Setup Termination from Responder=1,表示允许感知响应设备发起感知测量设置终止请求(但仍由感知发起设备决定是否终止感知测量设置);如果Sensing Measurement Setup Termination from Responder=0,表示不允许感知响应设备发起感知测量设置终止请求。注,也可取值相反,如0表示允许,1表示不允许。
按照该设置,感知响应设备可以发起/不发起感知测量设置终止请求。如果感知响应设备可以发起感知测量设置终止请求,后续流程与上述方案2的方式一相同,在此不再赘述。
如果感知响应设备不可以发起感知测量设置终止请求,仅由感知发起设备发起感知测量设置终止,则与上述方案1相同,在此不再赘述。
方案3:感知响应设备发起感知测量设置终止。
在本方案中,感知响应设备向感知发起设备发送感知测量设置终止帧,无须感知响应设备同意即可终止相关Sensing Measurement Setup。
如图10B所示,如果定义感知测量设置终止帧为需要确认的帧类型(Action),那么感知发起设备可以发送Ack帧或其他帧,以确认感知响应设备发起的感知测量设置终止(Sensing Measurement Setup Termination)。
如图10C所示,如果定义感知测量设置终止帧为不需要确认的帧类型(Action No Ack),那么感知发起设备不发送任何帧,默认执行Sensing Measurement Setup Termination。
感知响应设备发送的感知测量设置终止帧可以携带终止感知测量设置的原因,如携带在Reason Code field中,以利于感知发起设备下一步进行通信/感知调度。
以上介绍了感知测量设置终止过程的流程,以下介绍该流程中使用的感知测量设置终止请求帧(Sensing Measurement Setup Termination Request frame)和感知测量设置终止帧(Sensing Measurement Setup Termination frame)
图11A是根据申请实施例的一种感知测量设置终止请求帧的帧结构示意图。感知测量设置终止请求帧由感知响应设备发送,用于指示请求终止某个测量设置。
感知响应设备请求终止测量设置时,在一些实施方式中,可以在感知测量设置终止请求帧中指 示请求终止测量设置的原因,如在图11A中包括原因代码域(Reason Code),用于指示请求终止测量设置的原因。原因代码的长度可以为1个字节。
请求终止感知测量设置的原因可以包括以下至少之一:
自身电量低;
自身有较多缓存的上行数据需要发送;
自身将开启点对点通信。
例如,Reason Code取值为0表示自身电量较低;取值为1表示为了省电不再参与感知测量;取值为2表示自身有较多缓存的上行数据要发送,不再参与感知测量;取值为3表示自身将开启点对点通信(P2P),不再参与测量;4~255保留。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,只要保证每一种原因代码对应的值与其它原因代码的值不同即可。
如图11A所示,感知测量设置终止请求帧中可以包含是否存在原因代码字段(子域),用于指示感知测量设置终止请求帧中是否存在上述原因代码域。例如,是否存在原因代码子域取值为1,代表感知测量设置终止请求帧中存在原因代码域;是否存在原因代码子域取值为0,代表感知测量设置终止请求帧中不存在原因代码域。前述内容仅为举例,也可以采用1代表不存在,0代表存在。
图11B是根据申请实施例的另一种感知测量设置终止请求帧的帧结构示意图。与图11A不同的是,图11B所示的测量设置终止请求帧格式可以用于指示请求终止一个或多个测量设置。
例如,感知测量设置终止请求帧还包括以下至少一项:
测量设置数量字段,用于指示请求终止感知测量设置的数量;
测量设置标识列表字段,用于携带一个或多个感知测量设置的标识。
其中,测量设置标识列表字段包括一个或多个第二测量设置标识字段,每个测量设置标识字段用于携带一个感知测量设置的标识。
如图11B所示,上述测量设置数量字段可以为测量设置数量域;测量设置标识列表字段可以为测量设置标识列表域,其中包含一个或多个测量设置标识子域,每个测量设置标识子域携带一个请求终止的感知测量设置的标识。
测量设置标识列表域包含的测量设置标识子域的数量由测量设置数量域指示。例如,图11B中,测量设置数量域取值为N,则测量设置标识列表域中包含N个测量设置标识子域。
图11B所示帧结构中的其他内容与图11A相同,在此不再赘述。
图12A是根据申请实施例的一种感知测量设置终止帧的帧结构示意图。感知测量设置终止帧由感知发起设备发送,用于指示终止某个测量设置。
感知发起设备终止测量设置时,在一些实施方式中,可以指示接受/拒绝感知响应设备终止测量设置的请求,可以指示终止测量设置的原因,如在图12A中包括原因代码域(Reason Code),用于终止测量设置的原因。原因代码的长度可以为1个字节。
请求终止感知测量设置的原因可以包括以下至少之一:
上层应用指示终止感知测量设置;
感知响应设备请求终止感知测量设置。
例如,Reason Code取值为0表示上层应用指示的终止;取值为1表示感知响应设备请求的终止;2~255保留。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,只要保证每一种原因代码对应的值与其它原因代码的值不同即可。
感知响应设备接收到指示终止测量设置的感知测量设置终止帧后,终止所指示的测量设置;接收到指示拒绝终止测量设置的感知测量设置终止帧后,不得终止所指示的测量设置。
如图12A所示,感知测量设置终止帧中可以包括命令代码字段(如图12A中的命令代码子域),该命令代码子域可以包含在感知测量设置终止帧的命令代码域中。命令代码子域的长度可以为1个比特,示例性的,0表示终止测量设置,1表示拒绝终止测量设置;或者,1表示终止测量设置,0表示拒绝终止测量设置。
指示终止测量设置或拒绝终止测量设置。示例性的,0表示终止测量设置,1表示拒绝终止测量设置;或者,1表示终止测量设置,0表示拒绝终止测量设置。
进一步地,感知测量设置终止帧中还可以包括是否存在命令代码字段和是否存在原因代码字段。如图12A所示,感知测量设置终止帧包括命令和原因代码控制域,该命令和原因代码控制域包括是否存在命令代码子域和是否存在原因代码子域,分别用于指示感知测量设置终止帧中是否存在命令代码和原因代码。例如,是否存在命令代码子域取值为1时,代表感知测量设置终止帧中存在命令代码,取值为0时代表感知测量设置终止帧中不存在命令代码;或者,1表示不存在,0表示 存在。又如,是否存在原因代码子域取值为1时,代表感知测量设置终止帧中存在原因代码,取值为0时代表感知测量设置终止帧中不存在原因代码;或者,1表示不存在,0表示存在。
图12B是根据申请实施例的另一种感知测量设置终止帧的帧结构示意图。与图12A不同的是,图12B所示的测量设置终止帧格式可以用于指示终止一个或多个测量设置。
例如,感知测量设置终止帧还包括以下至少一项:
测量设置数量字段,用于指示终止感知测量设置的数量;
测量设置标识列表字段,用于携带一个或多个感知测量设置的标识。
其中,测量设置标识列表字段包括一个或多个第二测量设置标识字段,每个测量设置标识字段用于携带一个感知测量设置的标识。
如图12B所示,上述测量设置数量字段可以为测量设置数量域;测量设置标识列表字段可以为测量设置标识列表域,其中包含一个或多个测量设置标识子域,每个测量设置标识子域携带一个终止的感知测量设置的标识。
测量设置标识列表域包含的测量设置标识子域的数量由测量设置数量域指示。例如,图12B中,测量设置数量域取值为N,则测量设置标识列表域中包含N个测量设置标识子域。
图12B所示帧结构中的其他内容与图12A相同,在此不再赘述。
结合上述感知测量设置终止请求帧和感知测量设置终止帧,以下举几个具体示例。
示例1:
感知发起设备主动发送感知测量设置终止帧,感知测量设置终止帧可以携带Command Code,在Command Code中指示终止感知测量设置;也可以不携带Command Code,发送感知测量设置终止帧即表示指示终止感知测量设置。
如果Command Code指示终止感知测量设置,那么感知测量设置终止帧可以携带Reason Code,在Reason Code中指示终止感知测量设置的原因;也可以不携带Reason Code,无需指示终止感知测量设置的原因。
