本申请实施例中,"预定义"可以通过在设备(例如,包括接入点和站点)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现,本申请对于其具体的实现方式不做限定。比如预定义可以是指协议中定义的。
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。
WiFi Sensing是由802.11bf标准提出的一种802.11协议的功能增强,其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。
以下是WiFi Sensing的几种典型的应用场景以及相关的参数。
1、室内感知(Room Sensing):
低频:室内是否有人检测,室内人数检测,定位活动的人,检测人的运动等。
2、姿势识别(Gesture Recognition):
高频:短距离可以检测手指移动(<0.5m),中距离可以检测手部移动(0.5m~2m),长距离可以检测身体移动(2m~7m);面部/身体识别(<1m)等。
低频:智能家居设备控制-姿势检测(<3m)。
3、医疗(Health Care)
高频:喷嚏感知(<10m);
低频:跌倒检测(<10m);远程诊断,例如呼吸速率和心率诊断(<5m)等。
4、三维图像创建(3D Vision)
高频:使用多个STA感知并创建环境的三维图像。
5、车内感知(In car sensing)
高频:司机疲劳识别(<3m);
低频:车内乘客检测(<5m)。
在WiFi Sensing中可以具有多个WiFi Sensing角色(role)如下:
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。
在一些情况中,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,基于反射波的感知类型,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波获得sensing测量结果。
图2示出了一种Wi-Fi sensing过程的示意性图。如图2所示,Wi-Fi sensing过程可以包括如下阶段:
1、能力发现(Discovery)阶段
在该阶段,Sensing Initiator与Sensing Responder进行Wi-Fi Sensing能力信息的交换。
2、设置(set)阶段
在该set阶段,建立Sensing Session、指示Sensing Session中的Sensing Transmitter与Sensing Receiver的角色、以及设置其他感知会话传输参数等。
3、测量阶段(Measurement exchange)
Sensing Session中的Sensing Transmitter发送感知测量信号给Sensing Session中的Sensing Receiver,Sensing Receiver反馈测量结果等。
4、解除阶段(Teardown)
停止在上述阶段中所建立的Sensing Session。
通过上述应用场景可知,802.11bf支持高频以及低频频带上的WiFi Sensing。对于支持低频频带(例如,2.4GHz,5GHz或6GHz)的设备,则需要在低频频带上执行Wi-Fi sensing过程,对于支持高频频带(例如,60GHz)的设备,需要在高频频带上执行Wi-Fi sensing过程,对于同时支持低频频带和高频频带的设备,则需要在低频频带和高频频带上均执行Wi-Fi sensing过程。
如图3所示,仅支持低频频带的设备(例如STA 2)需要在低频频带上执行Wi-Fi sensing过程;仅支持高频频带的设备(例如STA 3)需要在高频频带上执行Wi-Fi sensing过程;同时支持低频频带与高频频带的设备(例如STA 4)则需要在低频和高频上分别执行Wi-Fi sensing过程,因此,Wi-Fi sensing过程有待优化。
另外,在一些场景中,Wi-Fi Sensing中可能存在多个设备(例如多个AP或多个Sensing Responders)或多基础服务集(Basic Service Set)(即multiple BSSID set)的场景,此情况下,如何进行Sensing 能力发现和设置也是个问题。
如图4所示场景中,多AP中的每个AP(AP1和AP2)均需要分别与STA1进行sensing能力发现和设置,该Wi-Fi sensing过程有待优化。
图5是根据本申请实施例的无线通信的方法20的示意性交互图,如图5所示,该方法20可以包括如下至少部分内容:
S201,第一设备在第一频带上发送第一信息,所述第一信息包括目标设备在至少一个频带上的感知能力信息。
可选地,在一些实施例中,所述第一设备在第一频带上发送第一信息可以包括:
所述第一设备在第一频带上通过组播或单播方式向至少一个第三设备发送所述第一信息。
在一些实施例中,所述第一设备为AP,或者STA。
在一些实施例中,所述第三设备为STA,或者AP。
在一些实施例中,所述第一设备可以在感知发现过程中发送所述第一信息。
在一些实施例中,所述第一设备为感知发现设备,即Sensing Initiator。
在本申请一些实施例中,所述第一信息包括所述第一设备在多个频带上的感知能力信息。
因此,第一设备通过在一个频带上携带该第一设备在多个频段上的感知能力信息,这样,该第一设备可以不必在多个频带上均执行感知能力发现过程,而是在一个频带上即可完成在多个频带上的感知能力发现过程,能够降低感知能力发现的信令开销。
在一些实施例中,所述多个频带包括所述第一频带。
在一些实施例中,所述第一频带为低频频带,例如2.4GHz,或5GHz,或6GHz,第一设备在低频频带上发送感知能力信息能够避免在高频频带采用定向波束扫描发射方式进行感知能力发现的耗时耗能问题。
在一些实施例中,所述第一设备在多个频带上的感知能力信息包括以下中的至少一项:
第一指示信息,用于指示所述第一设备是否具备在多个频带上的感知能力;
所述第一设备支持的感知频带信息;
所述第一设备支持的感知角色信息;
所述第一设备支持的感知类型信息。
在一些实施例中,所述感知角色信息包括以下中的至少一种:
感知发起设备,感知响应设备,感知发送设备,感知接收设备,感知处理设备。
在一些实施例中,所述感知类型信息包括以下中的至少一种:
基于信道状态信息CSI的感知(即CSI-based Sensing),基于反射波的感知(即Radar-based Sensing)。
其中,上述感知角色信息和感知类型信息的具体说明参考前文的相关描述,这里不再赘述。
在一些实施例中,所述第一设备支持的感知角色信息包括一组感知角色信息,所述一组感知角色信息对应所述第一设备所支持的每个感知频带。
也就是说,所述第一设备所支持的每个感知频带可以对应相同的感知角色信息。
在另一些实施例中,所述第一设备支持的感知角色信息包括所述第一设备在支持的每个感知频带上所支持的感知角色信息。也就是说,所述第一设备所支持的每个感知频带可以对应独立的感知角色信息。可选地,所述第一设备在每个感知频带上所支持的感知角色可以相同,或者也可以不同。
在一些实施例中,所述第一设备支持的感知类型信息包括一组感知类型信息,所述一组感知类型信息对应所述第一设备所支持的每个感知频带。也就是说,所述第一设备所支持的每个感知频带可以对应相同的感知类型信息。
在另一些实施例中,所述第一设备支持的感知类型信息包括所述第一设备在支持的每个感知频带上所支持的感知类型信息。也就是说,所述第一设备所支持的每个感知频带可以对应独立的感知类型信息。可选地,所述第一设备在每个感知频带上所支持的感知类型可以相同,或者也可以不同。
在又一些实施例中,所述第一设备支持的感知类型信息包括所述第一设备在支持的部分感知频带上所支持的感知类型信息。
例如,所述第一设备支持的感知类型信息可以包括所述第一设备在支持的高频频带上所支持的感知类型信息,不包括所述第一设备在支持的低频频带上所支持的感知类型信息。
由于低频信号的反射能力强,多径效应明显,不适合采用Radar-based Sensing的感知类型,也就是说,低频频带可能不支持Radar-based Sensing类型,因此,第一设备支持的感知类型信息可以不包括低频频带对应的感知类型信息。
应理解,在本申请实施例中,所述第一信息可以通过用于第一设备和第三设备进行通信的任一种 帧发送,本申请对此不作限定。
以下,结合具体场景,说明第一设备在多个频带上的感知能力信息的具体承载方式。
在一些实施例中,所述第一设备为接入点AP,第三设备为STA,所述第一设备在多个频带上的感知能力信息通过以下中的至少一种帧发送:
信标(Beacon)帧,探测响应(Probe Response)帧,关联响应(Association Response)帧。
在一些实施例中,所述第一信息可以在感知能力发现过程中发送。
如图6所示,所述第一设备为AP,所述第一设备为感知发起设备,则AP可以通过Beacon、Probe Response和Association Response中的至少一种帧发送给STA。STA接收到上述帧的至少一个帧时,可以获知AP在多个频带上的感知能力信息。
类似地,STA可以在向AP发送的请求帧中携带该STA在多个频带上的感知能力信息,从而AP可以获知STA在多个频带上的感知能力信息。例如,STA可以向AP发送关联请求帧,请求与AP进行关联,同时告知AP该STA在多个频带上的感知能力信息。
在另一些实施例中,所述第一设备为STA,第三设备为AP,所述第一设备在多个频带上的感知能力信息通过以下中的至少一种帧发送:
探测请求(Probe Request)帧,关联请求(Association Request)帧。
如图7所示,所述第一设备为STA,STA为感知发起设备,则STA可以通过Probe Request和Association Request中的至少一种帧向AP发送STA在多个频带上的感知能力信息。AP接收到上述帧的至少一个帧时,可以获知STA在多个频带上的感知能力信息。
如前所述,AP可以在向STA发送的帧中携带AP在多个频带上的感知能力信息,从而能够实现二者在多个频带上的感知能力信息的交互。
在一些实施例中,可以在Beacon帧、广播(broadcast)Probe Response帧、Probe Request帧和Probe Response帧、(Re)Association Request帧和(Re)Association Response帧中增加感知能力元素(Sensing Capabilities element),用于承载第一设备在多个频带上的感知能力信息。在另一些实施例中,也可以在其它相关帧结构中添加Sensing Capabilities element,或者,也可以在现有的帧结构的预留位中添加感知能力域(Sensing Capabilities field),用于承载上述第一信息,本申请实施例对于所述第一信息在帧中的承载方式不作具体限定。
图8是根据本申请一个实施例的Sensing Capabilities element的格式示意图。
如图8所示,该Sensing Capabilities element可以包括如下字段:元素(element)ID,长度(length)和感知能力(Sensing Capabilities)字段。
可选地,element ID字段所占的字节数可以为1个字节,length字段所占的字节数可以为1个字节,Sensing Capabilities字段所占的字节数可以根据所承载的内容确定,本申请对此不作限定。
继续见图8,Sensing Capabilities字段可以包括支持的感知频带(Sensing band support)字段,支持的感知角色(Sensing roles support)字段和支持的感知类型(Sensing type support)字段。
在一些实施例中,支持的感知频带字段可以采用比特位图(bitmap)方式指示第一设备所支持的感知频带。
作为示例,支持的感知频带字段占1个字节,8个比特,其中,该8个比特中的N个比特对应N个感知频带,其中,N表示感知频带的总个数。例如,若感知频带有2.4GHz,5GHz,6GHz和60GHz四种,则N可以为4,该N个比特中的每个比特对应一个感知频带,每个比特的取值用于指示第一设备是否支持对应的感知频带。假设B7~B4分别对应2.4GHz,5GHz,6GHz和60GHz,若B7~B4的取值为1101,则表示第一设备支持的感知频带为2.4GHz,5GHz和60GHz。
在一些实施例中,如图8所示,支持的感知角色字段可以包括第一设备在每个支持的感知频带上所支持的感知角色。此情况下,第一设备在每个支持的感知频带上所支持的感知角色可以相同,或者也可以不同。
在一些实施例中,如图8所示,支持的感知类型字段可以包括第一设备在每个支持的感知频带上所支持的感知类型。此情况下,第一设备在每个支持的感知频带上所支持的感知类型可以相同,或者也可以不同。
可选地,所述第一设备在每个支持的感知频带上所支持的感知角色字段所占的字节数可以为1个字节,或者其他字节数,本申请对此不作限定。
在一些实施例中,第一设备在每个支持的感知频带上所支持的感知角色字段可以采用比特位图方式指示第一设备在每个感知频带上所支持的感知角色。
作为示例,第一设备在每个支持的感知频带上所支持的感知角色字段占1个字节,8个比特,其中,该8个比特中的M个比特对应M种感知角色。例如,如图8所示,若感知角色有感知发起设备, 感知响应设备,感知发送设备,感知接收设备,则M为4,该4个比特中的每个比特对应一个感知角色,每个比特的取值用于指示是否支持对应的感知角色,例如,取值为1表示支持,取值为0表示不支持。假设B7~B4分别对应感知发起设备,感知响应设备,感知发送设备,感知接收设备,若B7~B3的取值为1010,则表示第一设备所支持的感知角色为感知发起设备和感知发送设备。
可选地,所述第一设备在每个支持的感知频带上所支持的感知类型字段所占的字节数可以为1个字节,或者其他字节数,本申请对此不作限定。
在一些实施例中,第一设备在每个支持的感知频带上所支持的感知类型字段可以采用比特位图方式指示第一设备在每个感知频带上所支持的感知类型。
作为示例,第一设备在每个支持的感知频带上所支持的感知类型字段占1个字节,8个比特,其中,该8个比特中的K个比特对应K种感知类型。例如,如图8所示,若感知类型有CSI-based Sensing和Radar-based Sensing,则K可以为2,该2个比特中的每个比特对应一个感知类型,每个比特的取值用于指示第一设备在感知频带上是否支持对应的感知类型,例如,取值为1表示支持,取值为0表示不支持。假设B7~B6分别对应CSI-based Sensing和Radar-based Sensing,若B7~B6的取值为10,则表示第一设备所支持的感知类型为CSI-based Sensing。
图9是根据本申请另一实施例的Sensing Capabilities element的格式示意图。
与图8所示的Sensing Capabilities element的格式的区别在于,在图9所示的Sensing Capabilities element的格式中,第一设备支持的感知类型信息可以只包括第一设备在支持的部分频带上所支持的感知类型信息,例如只包括第一设备在支持的高频频带上所支持的感知类型信息。
图10是根据本申请又一实施例的Sensing Capabilities element的格式示意图。
与图8所示的Sensing Capabilities element的格式的区别在于,在图10所示的Sensing Capabilities element的格式中,第一设备在支持的感知频带上所支持的感知角色和感知类型信息相同,即Sensing Capabilities element可以指包括一个感知角色字段和一个感知类型字段。
图11是根据本申请又一实施例的Sensing Capabilities element的格式示意图。
与图10所示的Sensing Capabilities element的格式的区别在于,在图11所示的Sensing Capabilities element的格式中,可以不包括第一设备所支持的感知频带字段,此情况下,Sensing Capabilities element中的感知角色信息和感知类型信息可以对应所述第一设备的工作频段。
需要说明的是,图8至图11示例的是在帧中通过新增Sensing Capabilities element的方式指示第一设备在多个频带上的感知能力信息,在其他实施例中,也通过新增Sensing Capabilities field的方式指示第一设备在多个频带上的感知能力信息,本申请对于该第一设备在多个频带上的感知能力信息的具体承载方式不作限定。
综上,第一设备可以向其他设备发送该第一设备在工作频段上的感知能力信息,或者也可以发送第一设备在多个频带上的感知能力信息,该第一设备在多个频带上的感知能力信息可以相同,或者也可以不同。
在本申请另一些实施例中,所述第一信息包括至少一个第二设备在至少一个频带上的感知能力信息。
在一些实施例中,所述第一设备为第一AP,所述至少一个第二设备包括所述第一AP邻近的至少一个第二AP。即第一AP可以携带其他AP的感知能力信息进行感知能力发现。这样,STA可以不必与所有的AP进行交互即可获取多个AP的感知能力信息,从而能够加快多AP部署场景中的感知能力发现过程。
在一些实施例中,AP之间可以在需要进行其他信息交互时,同时交互各自的感知能力信息。
在一些实施例中,所述至少一个第二设备在至少一个频带上的感知能力信息包括以下中的至少一项:
第二指示信息,用于指示所述至少一个第二设备是否具备在多个频带上的感知能力;
每个第二设备支持的感知频带信息;
所述每个第二设备支持的感知角色信息;
所述每个第二设备支持的感知类型信息。
在一些实施例中,所述第二指示信息可以通过bitmap方式指示所述至少一个第二设备是否具有在多个频带上的感知能力。例如,第二指示信息包括K个比特,对应K个第二设备,每个第二设备对应一个比特,每个比特的取值用于指示对应的第二设备是否具有在多个频带上的感知能力。
在一些实施例中,所述第二设备支持的感知角色信息包括一组感知角色信息,所述一组感知能力信息对应所述第二设备所支持的每个感知频带。也就是说,所述第二设备所支持的每个感知频带可以对应相同的感知角色信息。
在又一些实施例中,所述第二设备支持的感知角色信息包括所述第二设备在支持的每个感知频带上所支持的感知角色信息。也就是说,所述第二设备所支持的每个感知频带可以对应独立的感知角色信息。可选地,所述第二设备在每个感知频带上所支持的感知角色可以相同,或者也可以不同。
应理解,不同的第二设备所支持的感知角色信息可以相同,或者也可以不同。
在一些实施例中,所述第二设备支持的感知类型信息包括一组感知类型信息,所述一组感知类型信息对应所述第二设备所支持的每个感知频带。也就是说,所述第二设备所支持的每个感知频带可以对应相同的感知类型信息。
在另一些实施例中,所述第二设备支持的感知类型信息包括所述第二设备在支持的每个感知频带上所支持的感知类型信息。也就是说,所述第二设备所支持的每个感知频带可以对应独立的感知类型信息。可选地,所述第二设备在每个感知频带上所支持的感知类型可以相同,或者也可以不同。
在又一些实施例中,所述第二设备支持的感知类型信息包括所述第二设备在支持的部分感知频带上所支持的感知类型信息。例如,所述第二设备支持的感知类型信息可以包括所述第二设备在支持的高频频带上所支持的感知类型信息,不包括所述第二设备在支持的低频频带上所支持的感知类型信息。
应理解,不同的第二设备所支持的感知类型信息可以相同,或者也可以不同。
以下,结合具体场景,说明所述至少一个第二设备在至少一个频带上的感知能力信息的具体承载方式。
在一些实施例中,所述第一设备为AP,所述至少一个第二设备在至少一个频带上的感知能力信息通过以下中的至少一种帧发送:
信标(Beacon)帧,探测响应(Probe Response)帧。
如图12所示,第一设备为AP1,AP1可以获取邻近AP,例如AP2在至少一个频带上的感知能力信息,进一步地,在感知能力发现过程发送给STA。
例如,AP1作为感知发起设备发起感知能力发现过程时,可以通过Beacon帧或者Probe Response携带邻近AP的感知能力信息,这样,STA不必接收所有AP的Beacon(或者,与所有AP交互Probe Request/Probe Response后),即可获知其周边AP的感知能力信息,通过接收一个AP发送的Beacon帧或Probe Response帧获知其周边AP的感知能力信息,有利于加快多AP部署环境中感知能力发现过程。
在一些实施例中,所述至少一个第二设备在至少一个频带上的感知能力信息通过降低邻近报告(Reduced Neighbor Report,RNR)元素携带。
作为一个示例,所述至少一个第二设备在至少一个频带上的感知能力信息承载于Beacon帧和/或Probe Response帧的RNR element中的信标预定传送时间(Target Beacon Transmission Time,TBTT)信息集(Information set)域中。
图13示出了通过RNR element中的TBTT Information set filed承载邻近AP在至少一个频带上的感知能力信息的一例示意性格式图。
如图13所示,RNR element可以包括如下字段:element ID,length和邻近AP信息域(Neighbor AP Information Fields)。
作为示例,上述各个字段分别对应的字节数为1、1、6。
其中,Neighbor AP Information Fields包括如下字段:TBTT信息头(Information header),操作类别(Operating Class),信道号(Channel Number),TBTT Information set。
作为示例,上述各个字段分别对应的字节数为2、1、1和可变字节数(variable)
其中,TBTT Information set可以包括如下字段:
邻近AP TBTT偏移(offset),BSSID(可选),(short)SSID,BSS参数,20MHz PSD,多链路设备(Multi-Link Device,MLD)参数。
在一些实施例中,可以将邻近AP在至少一个频带上的感知能力信息添加到RNR element中的TBTT Information Set field内的MLD参数子域(subfield)后,例如,在MLD参数子域后新增感知能力(Sensing Capabilities)子域,用于承载邻近AP在至少一个频带上的感知能力信息。
应理解,在本申请实施例中,所述邻近AP在至少一个频带上的感知能力信息可以为邻近AP在单个频带上的感知能力信息,例如在工作频段上的感知能力信息,或者也可以为邻近AP在多个频带上的感知能力信息,本申请对此不作限定。
当邻近AP在至少一个频带上的感知能力信息为邻近AP在单个频带上的感知能力信息时,对于每个邻近AP而言,该邻近AP在单个频带上的感知能力信息的格式可以参考图11所示的Sensing Capabilities的格式。当邻近AP在至少一个频带上的感知能力信息为邻近AP在多个频带上的感知能 力信息时,对于每个邻近AP而言,该邻近AP在多个频带上的感知能力信息的格式可以参考图8-10中所示的Sensing Capabilities的格式,为了简洁,这里不再赘述。
与前述实施例类似,可以通过在帧中新增Sensing Capabilities element的方式指示所述至少一个第二设备在至少一个频带上的感知能力信息,也通过新增Sensing Capabilities field的方式指示至少一个第二设备在至少一个频带上的感知能力信息,本申请对于所述至少一个第二设备在至少一个频带上的感知能力信息的具体承载方式不作限定。
在本申请又一些实施例中,所述第一信息包括所述第一设备的非传输(nontransimitted)BSS在至少一个频带上的感知能力信息。
在一些实施例中,所述第一设备的nontransimitted BSS又称为虚拟BSS,第一设备的虚拟BSS可以为一个或多个。所述第一设备的传输(transimitted)BSS为第一设备用于发起感知能力发现的BSS。
在一些实施例中,所述第一设备的nontransimitted BSS在至少一个频带上的感知能力信息包括以下中的至少一项:

在一些实施例中,所述第一设备的每个nontransimitted BSS对应一个第三指示信息,用于指示该nontransimitted BSS是否具备在多个频带上的感知能力。
在另一些实施例中,所述第一设备的所有nontransimitted BSS对应一个第三指示信息,用于指示所有nontransimitted BSS是否具备在多个频带上的感知能力。
在一些实施例中,所述第一设备的非传输BSS支持的感知频带信息包括一组感知频带信息,所述一组感知频带信息对应所述第一设备的每个nontransimitted BSS。
也就是说,所述第一设备的每个nontransimitted BSS对应相同的感知频带信息。
在另一些实施例中,所述第一设备的非传输BSS支持的感知频带信息包括所述第一设备的每个非传输BSS分别支持的感知频带信息。
也就是说,所述第一设备的每个nontransimitted BSS对应独立的感知频带信息。
可选地,所述第一设备的每个nontransimitted BSS对应感知频带信息可以相同,或者也可以不同。
在一些实施例中,所述第一设备的nontransimitted BSS支持的感知角色信息包括一组感知角色信息,所述一组感知角色信息对应所述第一设备的每个nontransimitted BSS。
也就是说,所述第一设备的每个nontransimitted BSS对应相同的感知角色信息。
在另一些实施例中,所述第一设备的非传输BSS支持的感知角色信息包括所述第一设备的每个nontransimitted BSS所支持的感知角色信息。
也就是说,所述第一设备的每个nontransimitted BSS可以对应独立的感知角色信息。
可选地,所述第一设备的每个nontransimitted BSS对应的感知角色可以相同,或者也可以不同。
在一些实施例中,所述第一设备的nontransimitted BSS支持的感知类型信息包括一组感知类型信息,所述一组感知类型信息对应所述第一设备的每个nontransimitted BSS。
也就是说,所述第一设备的每个nontransimitted BSS对应相同的感知类型信息。
在另一些实施例中,所述第一设备的非传输BSS支持的感知类型信息包括所述第一设备的每个nontransimitted BSS所支持的感知类型信息。
也就是说,所述第一设备的每个nontransimitted BSS可以对应独立的感知类型信息。
可选地,所述第一设备的每个nontransimitted BSS对应的感知类型可以相同,或者也可以不同。
在一些实施例中,所述第一设备的nontransimitted BSS在支持的每个感知频带上所支持的感知角色信息相同,或者也可以不同。
在一些实施例中,所述第一设备的nontransimitted BSS在支持的每个感知频带上所支持的感知类型信息相同,或者也可以不同。
综上,所述第一设备的nontransimitted BSS支持的感知频带信息可以是设备粒度的,即所述第一设备的所有nontransimitted BSS对应相同的感知频带信息,或者也可以是nontransimitted BSS粒度的,即第一设备的每个nontransimitted BSS对应独立的感知频带信息。
所述第一设备的nontransimitted BSS支持的感知角色信息可以是设备粒度的,即所述第一设备的所有nontransimitted BSS对应相同的感知角色信息,或者也可以是nontransimitted BSS粒度的,即第一设备的每个nontransimitted BSS对应独立的感知角色信息。
从另一角度来说,所述第一设备的nontransimitted BSS支持的感知角色信息可以是感知频带粒度 的,例如,第一设备的nontransimitted BSS所支持的每个感知频带对应独立的感知角色,或者,第一设备的nontransimitted BSS所支持的每个感知频带对应相同的感知角色。
所述第一设备的nontransimitted BSS支持的感知类型信息可以是设备粒度的,即所述第一设备的所有nontransimitted BSS对应相同的感知类型信息,或者也可以是nontransimitted BSS粒度的,即第一设备的每个nontransimitted BSS对应独立的感知类型信息。
从另一角度来说,所述第一设备的nontransimitted BSS支持的感知类型信息可以是感知频带粒度的,例如,第一设备的nontransimitted BSS所支持的每个感知频带对应独立的感知类型,或者,第一设备的nontransimitted BSS所支持的每个感知频带对应相同感知类型。
以下,结合具体场景,说明所述第一设备的nontransimitted BSS在至少一个频带上的感知能力信息的具体承载方式。
在一些实施例中,所述第一设备的nontransimitted BSS在至少一个频带上的感知能力信息承载于多基础参数集标识(Multi-BSSID)element中的transimitted BSSID element中。
在一些实施例中,所述第一设备为AP,所述第一设备的nontransimitted BSS在至少一个频带上的感知能力信息通过以下至少一种帧发送:
信标(Beacon)帧,探测响应(Probe Response)帧。
例如,承载于Beacon帧或Probe Response帧中的Multi-BSSID element的transimitted BSSID中。
应理解,本申请实施例的Beacon帧可以为DMG Beacon帧。
如图14所示,第一设备为AP,AP的Multi-BSSID set包括transimitted BSSID1和nontransimitted BSSID2,其中,该nontransimitted BSSID2为该AP的虚拟BSS,该AP的transimitted BSSID1可以作为感知发起设备发起感知能力发现过程。进一步地可以在感知能力发现过程向STA发送的帧中携带nontransimitted BSSID2在至少一个频带上的感知能力信息。例如,在Beacon帧和/或Probe Response帧中携带nontransimitted BSSID2在至少一个频带上的感知能力信息,能够高效对Multi-BSSID set中的nontransimitted BSSID的感知能力进行发现。
图15是根据本申请一个实施例的Multi-BSSID element的格式示意图。
如图15所示,该Multi-BSSID element可以包括如下字段:element ID,length、最大BSSID指示(MaxBSSID indicator)、至少一个非传输BSSID描述子元素(nontransimitted BSSID profile subelement)、供应商指定子元素(Vendor Specific subelment)(如果存在)字段。
进一步地,nontransimitted BSSID profile subelement可以包括如下字段:
Subelement ID,Length和数据(data)。
其中,data字段可以包括如下字段:
非传输BSSID能力元素(nontransimitted BSSID Capability element),SSID element,多BSSID索引元素(Multiple BSSID-Index element)、至少一个元素(element),非继承元素(Non Inheritance element)(如果存在)。
在一些实施例中,如图15所示,可以在Multi-BSSID element中的每个nontransimitted BSSID profile subelement中增加Sensing Capabilities element,用于指示每个nontransimitted BSSID在至少一个频带上的感知能力信息。即每个nontransimitted BSSID对应独立的感知能力信息。
在另一些实施例中,如图16所示,可以在Multi-BSSID element中增加Sensing Capabilities element,用于指示所有nontransimitted BSSID的感知能力信息。即所有nontransimitted BSSID对应相同的感知能力信息。
应理解,在本申请实施例中,所述第一设备的nontransimitted BSS在至少一个频带上的感知能力信息可以为第一设备的nontransimitted BSS在单个频带上的感知能力信息,例如在工作频段上的感知能力信息,或者也可以为第一设备的nontransimitted BSS在多个频带上的感知能力信息。
需要说明的是,当第一设备的nontransimitted BSS在至少一个频带上的感知能力信息为第一设备的nontransimitted BSS在单个频带上的感知能力信息时,对于第一设备的每个nontransimitted BSS而言,该每个nontransimitted BSS在单个频带上的感知能力信息的格式可以参考图11所示的Sensing Capabilities的格式。当第一设备的nontransimitted BSS在至少一个频带上的感知能力信息为在第一设备的nontransimitted BSS在多个频带上的感知能力信息时,对于每个nontransimitted BSS而言,该每个nontransimitted BSS在多个频带上的感知能力信息的格式可以参考图8-10中所示的Sensing Capabilities的格式,为了简洁,这里不再赘述。
与前述实施例类似,可以通过在帧中新增Sensing Capabilities element的方式指示所述第一设备的nontransimitted BSS在至少一个频带上的感知能力信息,也通过新增Sensing Capabilities field的方式指示第一设备的nontransimitted BSS在至少一个频带上的感知能力信息,本申请对于该第一设备的 nontransimitted BSS在至少一个频带上的感知能力信息的具体承载方式不作限定。
综合前述实施例,第一设备在第一频带(例如低频频带)上进行感知能力发现时携带该第一设备在多个频带上(例如高频频带和低频频带)的感知能力信息,从而设备之间在一个频段上即可完成多个频带上的感知能力发现,降低了感知能力发现的开销。
另外,第一设备还可以携带其他设备在至少一个频带上的感知能力信息,例如在多AP场景下,一个AP既可以携带周边AP在一个频带上的感知能力信息,又可以携带周边AP在多个频带上的感知能力信息,有利于加快STA对AP的感知能力发现的过程。
此外,第一设备的Multi-BSSID set中的transmitted BSSID通过Multi-BSSID element携带nontransmitted BSSID在至少一个频带上的感知能力信息,这样,在第一设备具有Multi-BSSID set场景中,赋予了nontransmitted BSSID的感知能力发现的功能。
图17是根据本申请另一实施例的无线通信的方法30的示意性交互图,如图17所示,该方法可以包括如下至少部分内容:
S310,感知发起设备向感知响应设备发送第二信息,所述第二信息用于建立至少一个感知会话。
在一些实施例中,所述感知发起设备为AP,所述感知响应设备为STA。
在另一些实施例中,所述感知发起设备为STA,所述感知响应设备为AP。
在本申请一些实施例中,在S310之前,所述方法30还包括:
S301,感知发起设备和感知响应设备交互第一信息。
其中,所述感知发起设备和所述感知响应设备之间交互的第一信息的具体内容参考方法20中第一信息的相关实现,为了简洁,这里不再赘述。
作为示例,所述感知发起设备为AP,所述感知响应设备为STA,所述AP发送给STA的第一信息可以包括AP在多个频带上的感知能力信息,或者也可以包括邻近AP在至少一个频带上的感知能力信息,或者也可以包括AP的nontransmitted BSSID在至少一个频带上的感知能力信息等。STA发送给AP的感知能力信息可以包括该STA在多个频带上的感知能力信息。
在一些实施例中,所述第二信息包括以下信息中的至少一种:
所述至少一个感知会话的排序;
所述至少一个感知会话的感知频带信息;
所述至少一个感知会话的时间信息;
所述至少一个感知会话中的每个感知会话中的感知角色信息;

所述至少一个感知会话的用于感知测量的感知信道信息;
第四指示信息,所述第四指示信息用于指示是否需要对第三信息进行确认,其中,所述第三信息为所述第二信息的响应信息。
在一些实施例中,所述至少一个感知会话的排序可以为所述至少一个感知会话分别对应的编号,或者也可以用于指示所述至少一个感知会话的优先级顺序,即需要优先建立哪个感知会话。
在一些实施例中,所述第二信息可以不包括所述至少一个感知会话的感知频带信息,此情况下,可以认为所述至少一个感知会话对应的感知频带为该感知发起设备的工作频带。
在一些实施例中,所述第二信息也可以包括至少一个感知会话对应的多个感知频带。
在一些实施例中,所述至少一个感知会话的时间信息包括所述至少一个感知会话分别对应的开始时间和持续时间。

在一些实施例中,所述感知信道信息包括以下中的至少一种:
感知信道的编号、感知信道的信道带宽。
在本申请一些实施例中,所述第四指示信息所指示的内容可以根据感知会话的场景确定。例如,感知发起设备可以根据所述至少一个感知会话中的每个感知会话中的感知角色信息,确定所述第四指示信息所指示的内容。
在一些场景中,由于一个Sensing session中的Sensing Initiator可以不是Sensing Transmitter或Sensing Receiver,那么当建立Sensing session时,若有Sensing Transmitter或Sensing Receiver拒绝了Sensing Initiator建立Sensing session的请求,而该Sensing session中的其他Sensing role并不知道此情况,而会继续执行后续的感知测量阶段,导致不必要的信令开销。在本申请实施例中,感知发起设备可以指示感应响应设备对感应会话设置进行确认,以保证Sensing session中的各个Sensing role对于该Sensing session的建立的理解一致。
作为示例,若根据所述至少一个感知会话中的感知角色信息确定所述感知发起设备为所述至少一个感知会话中的唯一的感知发送设备,则确定所述第四指示信息指示不需要对所述第三信息进行确认。
作为示例,若根据所述至少一个感知会话中的感知角色信息确定所述感知发起设备为所述至少一个感知会话中的唯一的感知接收设备,则确定所述第四指示信息指示不需要对所述第三信息进行确认。
作为示例,若根据所述至少一个感知会话中的感知角色信息确定所述感知发起设备不是所述至少一个感知会话中的唯一的感知发送设备,确定所述第四指示信息指示需要对所述第三信息进行确认。
作为示例,若根据所述至少一个感知会话中的感知角色信息确定所述感知发起设备不是所述至少一个感知会话中的唯一的感知接收设备,确定所述第四指示信息指示需要对所述第三信息进行确认。
在一些实施例中,所述第二信息承载在感知请求(Sensing Request)帧中。此情况下,所述感应发起设备可以为AP或STA。
图18是感应发起设备通过Sensing Request帧发送第二信息,进行感知设置的示意性交互图。
在另一些实施例中,所述第二信息承载在关联请求(Association Request)帧中。即可以通过关联过程进行感知设置(Sensing set)。此情况下,所述感应发起设备可以为STA。
图19是感应发起设备通过Association Request帧发送第二信息,进行感知设置的示意性交互图。
在本申请一些实施例中,如图17所示,所述方法30还包括:
S320,感知响应设备向感知发起设备回复第三信息,该第三信息为所述第二信息的响应信息。
可选地,在一些实施例中,所述第三信息包括以下中的至少一种:
所述至少一个感知会话的排序;
所述至少一个感知会话的感知状态信息,用于指示所述感知响应设备是否同意建立感知会话。
在一些实施例中,所述至少一个感知会话的感知状态信息包括一个感知状态信息,所述一个感知状态信息用于指示感知响应设备是否同意建立所有感知会话。
在另一些实施例中,所述至少一个感知会话的感知状态信息包括至少一个感知状态信息,每个感知状态信息对应一个感知会话,每个感知状态信息用于指示感知响应设备是否同意建立对应的感知会话。例如,每个感知会话对应1比特的感知状态指示信息,该1比特的感知状态指示信息的取值用于指示是否同意建立该感知会话,例如,取值为1表示同意,取值为0表示不同意。
在一些实施例中,所述第三信息承载在感知响应(Sensing Response)帧中。此情况下,所述感知响应设备可以为AP或STA。
例如,当第二信息通过Sensing Request发送时,感知响应设备可以通过Sensing Response帧回复第三信息。
在另一些实施例中,所述第三信息承载在关联响应(Association Response)帧中。此情况下,所述感知响应设备可以为AP。
例如,当第二信息通过Association Request发送时,感知响应设备可以通过Association Response帧回复第三信息。
以下,以通过Sensing Request帧发送第二信息,通过Sensing Response帧回复第三信息为例进行说明,但本申请并不限于此。
在本申请一些实施例中,感知响应设备的数量可以为一个,记为场景一,即一对一的感知设置场景,此情况下,感知发起设备可以通过单播方式向感知响应设备发送所述第二信息。
在本申请另一些实施例中,感知响应设备的数量可以为多个,记为场景二,即一对多的感知设置,此情况下,感知发起设备可以通过单播方式或者组播方式发送所述第二信息。
对于场景二,若所述第二信息可以是通过组播方式发送的,则所述多个感知响应设备回复所述第三信息可以包括如下几种方式:
方式1:所述多个感知响应设备基于轮训帧(Poll)回复所述第三信息;
方式2:所述多个感知响应设备基于触发帧(Trigger)同时回复所述第三信息;
方式3:所述多个感知响应设备按照特定回复顺序依次回复所述第三信息;
对于场景二,若第二信息可以是通过单播方式发送的,则感知响应设备可以依次对单播接收到的第二信息进行回复。
以下结合图20至图23,以一个感知发起设备,两个感知响应设备为例说明感知请求帧和感知响应帧的发送方式。
如图20所示,感知发起设备可以通过组播方式向感知响应设备1和感知响应设备2发送感知请求帧进行感知设置,其中,感知请求帧包括前文所述的第二信息。
进一步地,感知响应设备1和感知响应设备2可以基于感知发起设备发送的Poll帧回复感知响应帧。
如图21所示,感知发起设备可以通过组播方式向感知响应设备1和感知响应设备2发送感知请求帧进行感知设置,其中,感知请求帧包括前文所述的第二信息。
进一步地,感知响应设备1和感知响应设备2可以基于感知发起设备发送的Trigger帧同时回复感知响应帧。
如图22所示,感知发起设备可以通过组播方式向感知响应设备1和感知响应设备2发送感知请求帧进行感知设置,其中,感知请求帧包括前文所述的第二信息。
可选地,所述感知请求帧中还可以包括感知响应帧的回复顺序,例如感知响应设备1先回复,感知响应设备2后回复。
进一步地,感知响应设备1和感知响应设备2可以根据感知发起设备指示的回复顺序依次进行感知响应帧的回复。
如图23所示,感知发起设备可以通过单播方式依次向感知响应设备1和感知响应设备2发送感知请求帧进行感知设置,其中,感知请求帧包括前文所述的第二信息。
则感知响应设备1和感知响应设备2可以依次对感知发起设备发送的感知请求帧进行感知响应帧的回复。
在本申请一些实施例中,如图17所示,所述方法30还包括:
S330,所述感知发起设备向感知响应设备发送第四信息,所述第四信息为对所述第三信息的确认信息。
在一些实施例中,所述第四信息承载于感应确认(Sensing Confirm)帧中。
在一些实施例中,所述感知发起设备可以在第四指示信息指示需要对第三信息进行确认的情况下,向感知响应设备回复第四信息。
在另一些实施例中,所述感知发起设备无论什么情况,都对第三信息进行确认。
在又一些实施例中,所述感知发起设备可以在存在被拒绝建立的感知会话的情况下,向被拒绝的感知会话中的感知角色所关联的设备进行确认。
在本申请一些实施例中,所述第四信息包括以下信息中的至少一种:
所述至少一个感知会话的排序;
所述至少一个感知会话对应的感知状态信息;
所述感知响应设备同意建立的目标感知会话的会话建立相关信息。
在一些实施例中,所述至少一个感知会话对应的感状态信息可以通过bitmap方式指示。例如,所述第四信息包括第一比特位图,所述第一比特位图包括P个比特对应P个感知会话,P为请求建立的感知会话的总数,每个比特对应一个感知会话,每个比特的取值用于指示是否同意建立对应的感知会话。
在一些实施例中,所述目标感知会话的会话建立相关信息包括以下中的至少一项:
所述目标感知会话的感知频带信息;
所述目标感知会话的时间信息;
所述目标感知会话中的每个感知会话中的感知角色信息;
所述目标感知会话的测量反馈类型;
所述目标感知会话的用于感知测量的感知信道信息。
可选地,所述目标感知会话的会话建立相关信息可以与感知请求帧中所携带的感知会话的会话建立相关信息相同,或者也可以与感知请求帧中所携带的感知会话的会话建立相关信息不同。
可选地,在同意建立的目标感知会话的会话建立相关信息与感知请求帧中所携带的感知会话的会话建立相关信息相同时,该第四信息中可以不包括目标感知会话的会话建立相关信息。
在一些实施例中,所述S330可以具体包括:
所述感知发起设备向所有感知响应设备均发送所述第四信息。
在另一些实施例中,所述S330可以具体包括:
所述感知发起设备向至少一个第一感知响应设备发送第四信息,其中,所述至少一个第一感知设备包括拒绝建立的感知会话所关联的感知响应设备。
感知发起设备通过向被拒绝建立的感知会话所关联的感知响应设备发送第四信息,从而这些感知响应设备可以获知被拒绝建立的感知会话的信息,从而能够避免被拒绝建立会话的感知响应设备继续执行后续的感知测量阶段,导致不必要的信令开销。
以下结合具体场景,说明感应设置过程的具体实现。
在一些场景中,如图24所示,待建立的Sensing Session为:Sensing Responder 1向Sensing Responder 2发送感知测量信号。
对于该Sensing Session,Sensing Initiator不是唯一的感知接收设备,则Sensing Initiator可以设置第四指示信息指示需要对第三信息进行确认,例如第四指示信息为1比特的会话确认指示,取值为1表示需要确认,取值为0表示不需要确认。
进一步地,Sensing Initiator通过向感知响应设备1和感知响应设备2发送Sensing Request帧请求建立该Sensing Session。
Sensing Responder 1和Sensing Responder 2可以向Sensing Initiator发送Sensing Response帧,Sensing Response帧的发送方式参考前述实施例的相关描述,这里不再赘述。
若Sensing Responder 1接受建立Sensing Session,而Sensing Responder 2拒绝建立该Sensing Session,则Sensing Responder 1没必要向Sensing Responder 2发送感知测量信号,但此时Sensing Responder 1并不知道Sensing Responder 2拒绝建立Sensing Session,所以需要Sensing Initiator进行sensing协商确认。
在一些实现方式中,Sensing Initiator发送Sensing Confirm帧给所有的Sensing Responder,进一步地,Sensing Responder 1根据Sensing Confirm帧中的感知会话的感知状态指示确定是否发送感知测量信号。
在另一些实现方式中,Sensing Session被拒绝,对于Sensing Responder 2是知道的,但是Sensing Responder 1并不知道,因此Sensing Initiator发送Sensing Confirm帧给Sensing Responder 1,在该Sensing Confirm帧中携带该Sensing Session的感知状态信息,从而Sensing Responder 1根据Sensing Confirm帧中的该Sensing Session的感知状态信息确定是否发送感知测量信号。
例如,Sensing Responder 1可以不必在该Sensing Session内向Sensing Responder 2发送感知测量信号,例如,可进入休眠或处于其它工作模式,Sensing Responder 2也可以不必在该Sensing Session对应的时间内保持接收感知测量信号,例如,可进入休眠或处于其它工作模式。
以下,结合具体实施例,说明第二信息、第三信息和第四信息在帧中的具体承载方式。
在一些实施例中,所述第二信息通过Sensing Request帧承载。例如,可以在Sensing Request帧中新增Sensing Request element,用于承载第二信息。或者也可以在Sensing Request帧中新增Sensing Request field,用于承载第二信息。
图25是通过Sensing Request帧携带Sensing Request element的格式示意图。
如图25所示,该Sensing Request element可以包括如下字段:element ID,length和感知请求(Sensing Request)字段。
可选地,element ID字段所占的字节数可以为1个字节,length字段所占的字节数可以为1个字节,Sensing Request字段所占的字节数可以根据所承载的内容确定,本申请对此不作限定。
继续参见图25,Sensing Request字段可以包括k个感知会话(Sensing Session)字段,最多承载k个Sensing Session的会话建立相关信息,其中,k为正整数。
在一些实施例中,每个Sensing Session字段可以包括如下字段:
会话次序(Session Order)、会话的开始时间(Start Time)、会话的持续时间(Duration)、感应信道(Sensing Channel)、感应会话中的Sensing Transmitter,感应会话中的Sensing Receiver,感应会话中的Sensing Processer,反馈类型(Feedback Type)、会话确认指示(Session Confirmed),用于指示是否需要进行会话确认。
在一些实施例中,感知会话字段中的感知角色字段可以包括感知角色对应的ID字段,用于承载该感知会话中的每个感知角色的ID。
应理解,图25所示格式中,感知会话中的各个感知角色字段所占的字节数仅为示意,例如,感知发送设备字段可以占m个字节,最多承载m个感知发送设备的ID,感知接收设备字段可以占n个字节,最多承载m个感知接收设备的ID,感知处理设备字段占x个字节,最多承载x个感知处理设备的ID,其中,m,n,x可以相同或不同。
在另一些实施例中,感知会话字段中的感知角色字段可以包括感知角色对应的数量字段和感知角 色对应的ID字段,用于承载该感知会话中的每个感知角色的数量以及ID。此情况下,每个感知角色字段所占的字节数可以是根据感知会话的场景确定。
可选地,上述各个字段所占的字节数可以为1、4、2、1、1、1、1、1、1、1、1、1,本申请对此不作限定。
在图25所示例的Sensing Request element中,可以不包括感知会话对应的感知频带信息,此情况下,可以认为感知会话对应的感知频带为该Sensing Initiator的工作频带。
图26是通过Sensing Request帧携带Sensing Request element的另一格式示意图。
与图25所示的格式的区别在于,每个Sensing Session字段还可以包括对应的感知频带字段。
在一些实施例中,所述第三信息通过Sensing Response帧承载。例如,可以在Sensing Response帧中新增Sensing Response element,用于承载第三信息。或者也可以在Sensing Response帧中新增Sensing Response field,用于承载第三信息。图27是通过Sensing Response帧携带Sensing Response element的格式示意图。
如图27所示,该Sensing Response element可以包括如下字段:element ID,length和感知响应(Sensing Response)字段。
可选地,element ID字段所占的字节数可以为1个字节,length字段所占的字节数可以为1个字节,Sensing Response字段所占的字节数可以根据所承载的内容确定,本申请对此不作限定。
继续参见图27,Sensing Response字段可以包括Sensing Session字段。
在一些实施例中,每个Sensing Session字段可以包括如下字段:
会话次序(Session Order)、会话的感知状态(Sensing Status),例如Sensing Status为1比特,该1比特取值为1表示接受,取值为0表示拒绝。
在图27所示例的Sensing Response element中,可以不包括感知会话对应的感知频带信息。
应理解,以上仅示例了通过Sensing Request帧和Sensing Response帧携带第二信息和第三信息的格式图,通过Association Request帧和Association Response帧携带第二信息和第三信息时,格式类似,为了简洁,这里不再赘述。
在一些实施例中,所述第四信息通过Sensing Confirm帧承载。例如,可以在Sensing Confirm帧中新增Sensing Confirm element,用于承载第四信息,或者也可以在Sensing Confirm帧中新增Sensing Confirm field,用于承载第四信息。
图28是通过Sensing Confirm帧携带Sensing Confirm element的格式示意图。
如图28所示,该Sensing Confirm element可以包括如下字段:element ID,length和感知确认(Sensing Confirm)字段。
可选地,element ID字段所占的字节数可以为1个字节,length字段所占的字节数可以为1个字节,Sensing Confirm字段所占的字节数可以根据所承载的内容确定,本申请对此不作限定。
继续参见图28,Sensing Confirm字段可以包括至少一个感知会话(Sensing Session)字段。
其中,至少一个Sensing Session字段可以用于承载同意建立的感知会话的会话建立相关信息。
例如,感知会话a和感知会话b是同意建立的感知会话,则可以在Sensing Confirm帧中携带感知会话a和感知会话b的会话建立相关信息。
在一些实施例中,每个Sensing Session字段可以包括如下字段:
会话次序(Session Order)、会话的开始时间(Start Time)、会话的持续时间(Duration)、感应信道(Sensing Channel)、感应会话中的Sensing Transmitter,感应会话中的Sensing Receiver,感应会话中的Sensing Processer,反馈类型(Feedback Type)。
可选地,上述各个字段所占的字节数可以为1、4、2、1、1、1、1、1、1、1、1,本申请对此不作限定。
在一些实施例中,感知会话字段中的感知角色字段可以包括感知角色对应的ID字段,用于承载同意建立的感知会话中的每个感知角色的ID。
在另一些实施例中,感知会话字段中的感知角色字段可以包括感知角色对应的数量字段和感知角色对应的ID字段,用于承载该感知会话中的每个感知角色的数量以及ID。此情况下,每个感知角色字段所占的字节数可以是根据感知会话的场景确定。
应理解,图28所示格式中,感知会话中的各个感知角色字段所占的字节数仅为示意,例如,感知发送设备字段可以占m个字节,最多承载m个感知发送设备的ID,感知接收设备字段可以占n个字节,最多承载m个感知接收设备的ID,感知处理设备字段占x个字节,最多承载x个感知处理设备的ID,其中,m,n,x可以相同或不同。
需要说明的是,若同意建立的感知会话对应的会话建立相关信息和请求建立的感知会话对应的会 话建立相关信息相同,该Sensing Confirm帧中可以只包括同意建立的感知会话的会话次序,不包括会话建立相关信息,从而能够降低Sensing Confirm帧的开销。
在图28所示例的Sensing Confirm element中,可以不包括感知会话对应的感知频带信息,此情况下,可以认为感知会话对应的感知频带为该Sensing Initiator的工作频带。
图29是通过Sensing Confirm帧携带Sensing Confirm element的另一格式示意图。
与图28所示的格式的区别在于,每个Sensing Session字段还可以包括对应的感知频带字段。
在一些实施例中,所述第四信息通过Sensing Confirm帧承载。例如,可以在Sensing Confirm帧中新增Sensing Confirm element,用于承载第四信息。或者也可以在Sensing Confirm帧中新增Sensing Confirm field,用于承载第四信息。
综上,本申请实施例通过设计一个Sensing Initiator与多个Sensing Responder之间进行感知设置的过程,可以加快一对多的感知设置的过程。此外,针对STA是Sensing Initiator的情况,可以将感知设置过程与设备的关联过程融合,有利于降低了信令开销并加快了感知设置的过程。
并且,针对具有多个Sensing Responder的场景,当存在Sensing Responder拒绝建立Sensing session时,那么对应的Sensing Transmitter和/或Sensing Receive无法获知Sensing设置的结果,仍在拒绝的Sensing session内保持唤醒状态,造成了时间和电量的浪费。本申请实施例通过设计Sensing Initiator根据会话的场景确定是否需要确认感知设置结果的机制,加快感知设置确认的过程。并且通过对会话的感知设置结果进行确认,能够使得被拒绝的对应的Sensing session的Sensing Transmitter和/或Sensing Receive可以获知Sensing设置的结果,这样,Sensing Transmitter和/或Sensing Receive可以在Sensing session的持续时间内进入非工作模式,例如休眠模式,从而能够降低电量的消耗。
