本公开实施例提供了一种通信方法及装置、电子设备及存储介质,用以提供一种NDPA帧的格式。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图1中所示,本公开实施例提供了一种通信方法,可选地,所述方法可应用于网络设备,所述网络设备为发起端(Sensing Initiator),所述发起端可以是无线局域网络感知测量过程的感知发射端(Sensing Transmitter)或不参与无线局域网络感知测量过程的设备。
该方法可以包括以下步骤:
步骤101,确定目标无线帧;其中,所述目标无线帧包括第一标识位,所述第一标识位指示所述目标无线帧的类型为无线局域网感知空数据包通告帧。
作为第一示例,参见图2至图4,首先介绍本公开实施例提供的通信方法所应用的WLAN Sensing的架构以及WLAN Sensing过程。
图2示出了一种WLAN Sensing的架构示意图;其中,感知发起端(Sensing Initiator)发起WLAN Sensing(例如,发起WLAN感知会话),可能存在着多个感知响应端(Sensing Responder,或感知接收端)对其响应,如图2中的响应端1、响应端2和响应端3所示。当感知发起端发起WLAN Sensing时,多个关联或者非关联的WLAN Sensing的感知响应端可以进行响应;如图2所示,响应端1、响应端2和响应端3可以分别与发起端具有关联关系(associated)或不具有关联关系(unassociated)。其中,“关联”可以指感知发起端与感知响应端之间建立了用于通信的关联连接,“非关联”可以指感知发起端与感知响应端之间未建立用于通信的关联连接。
参见图3,感知发起端与感知响应端之间通过通信连接通信,如通信连接S1所示;感知响应端之间通过通信连接S2通信。
其中,每个感知发起端可以是一个客户端(Client);每个感知响应端(在本示例中,即感知响应端1至感知响应端3)可以是一个站点设备(STA)。STA可以在WLAN感知过程中承担多个角色,例如,在WLAN感知过程中,感知发起者可能是感测发射器(Sensing Transmitter)、感知接收器(Sensing Receiver),或两者都是,或都不是。在WLAN感测过程中,感测响应端也可能是感测发射器、感测接收器或两者都是。
作为另一种架构,如图4所示,感知发起端、感知响应端还可以均为客户端,二者可以通过连接到同一AP进行通信;图4中Client1为感知发起端,Client2为感知响应端。
在WLAN感知过程中,发起端确定目标无线帧,在目标无线帧中携带第一标识位,第一标识位用于指示所述目标无线帧的类型为WLAN Sensing NDPA帧。在WLAN Sensing场景中,NDPA(Null Data Packet Announcement)帧用于指示响应端发送空数据包(NullDataPacket,NDP)。
作为第二示例,参见图5,图5示出了一种WLAN Sensing场景,可以包括以下过程:
Polling、UL Sensing Sounding、DL Sensing Sounding及Key Update,其中key update是指LTF(longtrainingfield)的随机密钥的更新,LTF是NDP帧的重要组成部分。
在Polling过程中,感知发起端AP执行对感知接收端STA1至STA5的轮询过程;且作为感知发射端(图5中Sensing Transmitters)的STA1至STA2,作为感知接收端(图5中Sensing Receivers)的STA3至STA4均启用CTS-to-self保护机制,同时也标识站点的存在。
在UL Sensing Sounding中,感知发起端AP对STA1与STA2执行感知探测;STA1至STA2分别发送空数据(Null Data Packet,NDP)帧,其中NDP包括短训练域(Short Training Field,STF)及长训练域(Long Training Field,LTF)。
在DL Sensing Sounding过程中,感知发起端AP向作为感知响应端的STA3与STA4发送目标无线帧,在目标无线帧中携带第一标识位,指示该无线帧为NDPA帧(即图4中:NDPA toSTA3-4),并发送NDP帧;STA3与STA4接收到目标无线帧之后,分别向AP发送NDP帧。
在Key Update流程中,感知发起端AP执行LTF信息更新。
在上述过程中,同作为感知响应端的STA5发送SIFS帧,SIFS用来间隔需要立即响应的帧,在帧交换顺序的两次传输之间使用最短间隔,可以防止其它正在等待介质的站点试图使用介质。
参见图6,作为另一种WLAN Sensing场景,可以包括以下过程:
UL Sensing Sounding、DL Sensing Sounding及Key Update。
在UL Sensing Sounding中,STA1发送目标无线帧,在目标无线帧中携带第一标识位,指示该无线帧为NDPA帧,并发送NDP帧。
在DL Sensing Sounding过程中,感知发起端AP向作为感知响应端的 STA1发送NDP帧。
在Key Update流程中,AP执行LTF信息更新。
步骤102,发送所述目标无线帧。
发起端向响应端发送所述目标无线帧,以指示响应端该无线帧的类型为NDPA帧,使得响应端根据NDPA帧向发起端发送NDP帧。
作为示例,目标无线帧可采用如以下表1中的形式标识所述第一标识位:
表1:
如表1中所示,可在目标无线帧中设置NDPA类型子字段,该字段占用2个比特(表1中所示为B0和B1),其不同值表示不同的NDPA帧变量;例如,“00”表示帧类型为VHT(Very High Throughput)NDPA帧,“01”表示帧类型为测距NDPA帧,“10”表示帧类型为HE(High-Efficiency)NDPA帧,“11”表示帧类型为无线局域网感知NDPA帧。
本公开实施例中,发起端确定目标无线帧并发送所述目标无线帧,所述目标无线帧包括第一标识位,所述第一标识位指示所述目标无线帧的类型为WLAN感知空数据包通告帧;本公开实施例提供了一种NDPA帧的格式,实现WLAN感知测量。
在一个可选实施例中,所述目标无线帧包括空数据包通告NDPA类型域,所述目标标识位携带在所述NDPA类型域中;例如,目标无线帧的格式如以下表2所示:
表2:
其中,目标无线帧包括NDPA类型域以及探测对话令牌号域;NDPA类型域包括2个比特,分别为B0以及B1;探测对话令牌号域包括6个比特,即B2以及B7。
在一个可选实施例中,所述目标无线帧包括探测对话令牌号域;
所述探测对话令牌号域中包括感知测量会话的会话标识以及所述感知测量会话包括的测量事件的事件标识;如以上表2中的示例所示,Sounding Dialog Token Number域包括6个比特位,其中每个值为感知测量会话ID与64取模值(mod运算);此外,由于每个测量会话可能包含多个测量事件,可能需要新增新的比特位来标识每个测量事件ID,例如新增6个比特位。
或用表2中所示6个比特位中的3个比特位标识测量会话ID,剩余3个比特位来标识测量事件ID。
可选地,Sounding Dialog Token Number值的可获取自Sensing Session Setup过程。
在一个可选实施例中,所述目标无线帧包括一个站点信息STA info域;
所述STA info域中包括关联标识符AID标识位或用户标识符UID标识位,所述AID标识位或UID标识位指示所述感知探测的响应端;AID表示关联标识符(Association Identifier),UID表示用户标识符(User Identifier)。
以非基于触发帧(Non-Triggered Based Sounding,Non-TB)的探测为例,例如DL sounding过程中,NDPA帧中可以只包含一个STA info子域,其包含的AID比特位或UID比特位,可以为2047,用于标识AP作为感知测量的响应端。
在一个可选实施例中,所述STA info域还包括序列验证码SAC(Sequence Authentication Code)标识位,所述SAC标识位指示所述目标无线帧使用加密的长训练域LTF(Long Training Field)。
在一个可选实施例中,所述目标无线帧的接入地址RA(Receiver Address)包括所述发起端的介质访问控制层MAC地址,即NDPA帧的RA为发起端的MAC地址。
在一个可选实施例中,所述目标无线帧包括至少一个STA info域;
所述STA info域中包括:所述发起端在关联过程中分配给响应端的AID标识位。以基于触发帧(TB sounding)的探测为例,例如UL sounding过程中,NDPA帧中可以可能包括一个或至少两个STA info子域,其包含的AID比特位为发起端(例如AP)在关联过程中分配给响应端(例如STA)的。
在一个可选实施例中,所述目标无线帧还包括:R2I NSS域、NSS repetition域、I2R NSS域及NSS repetition域中的至少一种。其中,R2I为由RSTA(Responding STA)发送到ISTA(initiating STA),I2R为由ISTA发送到RSTA;NSS指示空间流数(Number Of Spatial Stream), NSS repetition指示NSS重复次数。
在一个可选实施例中,所述目标无线帧的接收地址RA包括广播地址或单播地址;广播地址即面向所有响应端(例如STA)广播的地址,所述单播地址包括每个所述响应端的介质访问控制层MAC地址。
在一个可选实施例中,所述发送目标无线帧之后,所述方法还包括:
接收响应端发送的空数据包NDP;
或
向所述响应端发送触发帧,并接收所述响应端发送的NDP。
其中,对于Non-TB sounding的场景,响应端可在接收NDPA帧之后,直接向发起端发送DNP;对于TB sounding的场景,发起端在发送DNPA帧之后,向响应端发送触发帧,然后响应端基于所述触发帧向所述发起端发送NDP。
本公开实施例中,发起端确定目标无线帧并发送所述目标无线帧,所述目标无线帧包括第一标识位,所述第一标识位指示所述目标无线帧的类型为WLAN感知空数据包通告帧;本公开实施例提供了一种NDPA帧的格式,使得WLAN sensing机制得以应用,感知发起端以及响应端能够实现WLAN sensing并及时反馈测量事件结果,减小对其他设备的干扰。

无线帧接收模块901,用于接收目标无线帧,获取所述目标无线帧中携带的第一标识位,所述第一标识位指示所述目标无线帧的类型为无线局域网感知空数据包通告WLAN Sensing NDPA帧;
作为第一示例,参见图2至图4,首先介绍本公开实施例提供的通信方法所应用的WLAN Sensing的架构以及WLAN Sensing过程,具体内容参见前述实施例,在此不再赘述。
作为第二示例,参见图5至图6,示出了两种WLAN Sensing场景。
图5示出的WLAN Sensing场景,可以包括以下过程:
Polling、UL Sensing Sounding、DL Sensing Sounding及Key Update。
在Polling过程中,感知发起端AP执行对感知接收端STA1至STA5的轮询过程;且作为感知发射端(图5中Sensing Transmitters)的STA1至STA2,作为感知接收端(图5中Sensing Receivers)的STA3至STA4均启用CTS-to-self保护机制,同时也标识站点的存在。
在UL Sensing Sounding中,感知发起端AP对STA1与STA2执行感知探测;STA1至STA2分别发送空数据(Null Data Packet,NDP)帧,其中NDP包括短训练域(Short Training Field,STF)及长训练域(Long Training Field,LTF)。
在DL Sensing Sounding过程中,感知发起端AP向作为感知响应端的STA3与STA4发送目标无线帧,在目标无线帧中携带第一标识位,指示该无线帧为NDPA帧(即图4中:NDPA toSTA3-4),并发送NDP帧;感知响应端STA3与STA4接收到目标无线帧之后,分别向AP反馈NDP帧。
在Key Update流程中,感知发起端AP执行LTF信息更新。
在上述过程中,同作为感知响应端的STA5发送SIFS(Short Inter Frame Space)帧,SIFS用来间隔需要立即响应的帧,在帧交换顺序的两次传输之间使用最短间隔,可以防止其它正在等待介质的站点试图使用介质。
参见图6,作为另一种WLAN Sensing场景,可以包括以下过程:
UL Sensing Sounding、DL Sensing Sounding及Key Update。
在UL Sensing Sounding中,STA1发送目标无线帧(即NDPA帧),在目标无线帧中携带第一标识位,指示该无线帧为NDPA帧,并发送NDP帧。
在DL Sensing Sounding过程中,感知发起端AP向作为感知响应端的STA1发送NDP帧。
在Key Update流程中,AP执行LTF信息更新。

在一个可选实施例中,所述处理模块包括:
第一发送子模块,用于接收所述发起端发送的触发帧,并向所述发起端发送空数据包NDP;
或
