  • IEEE 802.11bf is a new generation wireless standard that focuses on the perception of passive objects (that is, the target does not carry any equipment). 11bf estimates the corresponding parameters (such as speed, distance, angle, etc.) of the target and subsequent actions based on the received signal. /behavior recognition. 802.11bf includes two major categories of standards: low frequency (sub7GHz, implementation mainly relies on 11ac, 11ax, 11be and next generation standards) and high frequency (60GHz, implementation mainly relies on 11ad, 11ay and next generation standards). The technical solution of this application can be applied to high frequencies (11ad/DMG, 11ay/EDMG) and low frequencies (standards corresponding to sub7GHz).
  • DMG/EDMG Due to the stronger attenuation of high-frequency electromagnetic waves themselves, existing high-frequency standards DMG/EDMG generally use directional beams for transmission and reception, which is quite different from the standards in low-frequency sub7GHz. But compared with low frequency, high frequency has a larger bandwidth, higher carrier frequency, and better perceptual performance. Directional transmission can also provide some angle information and reduce certain interference, helping to enhance perception performance.
  • the high frequency (11ad, 11ay) of 802.11bf supports monostatic, bistatic and multistatic sensing modes.
  • the monostatic mode is a spontaneous and self-receiving sensing mode, that is, the same device is used for transmitting and receiving. In this mode, transmitting and receiving are located in the same device at the same time, which can achieve better (time, frequency) synchronization and better perception performance.
  • Dual-base mode is a sensing mode in which the transmitter and receiver are separated. It can also be called passive sensing, that is, the transmitter and the receiver are two independent devices. In this mode, transmitting and receiving do not exist in the same device, and perceived performance may be potentially affected (out of sync).

参见图1，图1是本申请实施例提供的一种系统架构图。如图1所示，该系统架构包括至少2个WLAN设备(如图1中以包括一个AP和3个STA作为举例说明)，其中一个WLAN设备可以进行自发自收感知(如STA)，其他WLAN设备(如AP)向进行自发自收感知的WLAN设备请求感知结果。其中，WLAN设备可以支持WLAN通信协议。
本申请中，实现本申请方法的装置可以是WLAN中的PCP/AP或STA，或者是，安装在PCP/AP或STA中的芯片或处理系统。
PCP/AP是一种具有无线通信功能的装置，支持采用WLAN协议进行通信，具有与WLAN网络中其他设备(比如站点或其他接入点)通信的功能，当然，还可以具有与其他设备通信的功能。在WLAN系统中，接入点可以称为接入点站点(AP STA)。该具有无线通信功能的装置可以为一个整机的设备，还可以是安装在整机设备中的芯片或处理系统等，安装这些芯片或处理系统的设备可以在芯片或处理系统的控制下，实现本申请实施例的方法和功能。本申请实施例中的PCP/AP是为STA提供服务的装置，可以支持802.11系列协议。例如，AP可以为通信服务器、路由器、交换机、网桥等通信实体；PCP/AP可以包括各种形式的宏基站，微基站，中继站等，当然PCP/AP还可以为这些各种形式的设备中的芯片和处理系统，从而 实现本申请实施例的方法和功能。

下面首先介绍本申请实施例中所涉及的术语和技术特征。
一、802.11bf
IEEE 802.11bf是关注无源物体(即目标不携带任何设备)感知的新一代无线标准，11bf基于接收到的信号，对于目标进行相应的参数(如速度，距离，角度等)估计及后续的动作/行为识别。802.11bf包含低频(sub7GHz，实现方式主要依托11ac，11ax，11be及下一代等标准)和高频(60GHz，实现方式主要依托11ad，11ay及下一代等标准)两个大类标准。本申请的技术方案可以适用于在高频(11ad/DMG，11ay/EDMG)，也可以适用于低频(sub7GHz对应的标准)上。
由于高频电磁波自身的衰减更强，现有高频标准DMG/EDMG一般使用定向波束进行发送接收，这一点与低频sub7GHz中的标准区别较大。但是相对于低频，高频具有更大的带宽，更高的载频，感知性能较好。定向发送也可以提供一些角度信息，并且可以减少一定的干扰，有助于感知性能的增强。
802.11bf的高频(11ad，11ay)支持单基地(monostatic)，双基地(bistatic)和多基地(multistatic)感知模式。
单基地模式是一种自发自收的感知模式，即发射和接收使用同一个设备。该模式下，发射和接收同时位于同一设备之中，可以实现较好的(时间、频率)同步，感知性能较好。
双基地模式是一种收发分置的感知模式，也可以称为被动感知，即发射和接收为两个独立工作的设备。该模式下，发射和接收并不存在同一设备之中，感知性能潜在会收到(不同步)的影响。
多基地模式是一种一/多发多收，或者多发一/多收的感知模式。该模式下存在多个设备联合工作，相当于多个单/双基地模式的混合工作模式。
二、802.11ad/ay中的信标间隔(beacon interval，BI)
在802.11ad/ay中，时间轴被划分成各个BI。图2为信标间隔BI的结构示意图，如图2所示，信标间隔分为信标头指示(beacon header indication，BHI)和数据传输间隔(data transmission interval，DTI)。其中，BHI中又包括信标传输间隔(beacon transmission interval，BTI)、关联-波束赋形训练(association beamforming training，A-BFT)以及公告传输间隔(announcement transmission interval，ATI)。
具体地，PCP/AP会在BTI中按照扇区编号发送多个信标(beacon)帧，用于下行扇区扫描；A-BFT用于STA进行关联，以及上行扇区扫描；ATI用于PCP/AP向STA轮询缓存数据 信息以及向STA分配数据传输间隔(data transmission interval，DTI)中的资源。整个DTI会被分为若干个子区间，子区间会根据接入的形式分为基于竞争接入区间(contention based access period，CBAP)和服务区间(service period，SP)，后者是进行调度传输，无需进行竞争。
三、基于DMG Beacon的被动感知
AP首先在Beacon中携带一个sensing short capability element，表明AP支持passive被动感知。如果环境中的STA想要利用AP发送的Beacon信息进行感知，可以向AP发送信息请求Information request帧，请求AP发送Beacon的相关信息。AP通过information response帧向STA发送Beacon的发送信息(如发送时间，发送波束方向等)。STA可以通过这些信息，接收AP发送的Beacon，并根据Beacon的发送信息进行被动感知。
四、SSW帧和Short SSW帧
802.11ad中的波束训练主要在关联波束赋形训练(Association BFT，A-BFT)期间进行。首先，在BTI阶段，PCP/AP在各个方向上发送Beacon帧，该帧中的A-BFT Length字段指示了A-BFT阶段的时隙总长度，收到该帧的STAs会在接下来的A-BFT阶段随机选择[0，A-BFT Length-1]中的一个时隙接入，然后用定向天线依次发送SSW帧(即RXSS)，此时，PCP/AP会用准全向天线接收来自各个方向的波束并记录STAs的最佳发射波束。随后，进入扇区级扫描反馈阶段(SSW Feedback)，此时PCP/AP会以定向波束向STAs反馈上一阶段(RSS)的训练信息，反馈信息是按照扇区质量进行排序的发起方发送扇区列表，并且包含上一阶段应答方的最佳扇区，此时应答方处于准全向接收模式。最后，进入扇区扫描确认(SSW ACK)阶段，其中在数据传输阶段(DTI)之前做SLS时可以不存在SSW ACK阶段，在DTI阶段做SLS则需要有SSW ACK阶段。在SSW ACK阶段，STAs反馈按照质量排序的应答方发送扇区列表。
此外，为了满足更多用户的接入训练需求，在802.11ay中新加入了EDGM STA类型，与802.11ad中传统DGM STA不同的是，其可在A-BFT阶段所规划的A-BFT slot中既可以传输SSW帧也可以传输Short SSW帧，Short SSW帧相比于SSW帧，其帧长更短，可以让EDGM STA在一个slot中传输更多。
图3是本申请实施例提供的一种自发自收感知方法的流程示意图。该自发自收感知方法可以应用于如图1所示的通信系统中，其中，第一设备可以是如图1所示的PCP/AP，或者，该第一设备可以是如图1所示的STA。如图1所示，该方法包括：
101、第一设备基于第一帧结构进行自发自收感知，获得第一感知结果。
102、第二设备向第一设备发送第一请求帧，该第一请求帧用于请求获取自发自收感知结果。相应的，第一设备接收该第一请求帧。
103、第一设备根据第一请求帧，向第二设备发送第一响应帧，该第一响应帧包括第一感知结果。相应的，第二设备接收该第一响应帧。
其中，第一设备可以是PCP/AP或者STA，若第一设备为PCP/AP，该第一帧结构包括以下中的一种：DMG信标帧、数据帧或者BRP；若第一设备为STA，该第一帧结构为以下中的一种：扇区扫描SSW、Short SSW、BRP或者数据帧。其中，第一帧结构后面可以携带训练字段(Training Field，TRN)，该TRN由于会进行扫描，更有助于感知。
示例性的，当PCP/AP具备自发自收感知能力时，可以基于DMG信标帧Beacon、数据帧或BRP进行自发自收感知，获得第一感知结果。当STA具备自发自收感知能力时，可以 基于SSW、Short SSW、数据帧或BRP进行自发自收感知，获得第一感知结果。

在该种可能的实现方式中，第二设备可以进行被动感知，也可以不进行被动感知，即自发自收感知与被动感知并不绑定，提高自发自收感知方式的灵活性。
图4是本申请实施例提供的另一种自发自收感知方法的流程示意图。图4中的方法流程为图3中的方法的一种可能的实现方式。如图4所示，该方法包括：
201、第一设备通过第三信息宣称具备自发自收感知能力，通过第四信息宣称具备被动感知能力。
在一些实施方式中，第一设备发送第三信息和第四信息，该第三信息用于宣称第一设备具备自发自收感知能力，或者，该第三信息用于指示该第一设备支持自发自收感知。该第四信息用于宣称第一设备具备被动感知能力，或者，该第四信息用于指示该第一设备支持被动感知，其他设备可以向该第一设备请求发送波束信息和位置信息。第一设备可以是通过广播、组播或单播的方式发送该第三信息和第四信息。相应的，第二设备接收该第三信息和第四信息。

本申请实施例中，通过在Short Sensing Capabilities字段中新添加一个Monostatic Sensing Support子字段，用来明确AP是否支持自发自收感知。如果Passive Sensing Support为1，且Monostatic Sensing Support为1，该比特位组合表示AP可以支持Beacon Passive Sensing且可以提供基于Beacon的自发自收感知结果。可理解，新增加Monostatic Sensing Support子字段之后，Short Sensing Capabilities中的sensing support字段用于表示支持除被动感知和自发自收感知外的任何一种感知模式。
在第二种可选的实施方式中，第一设备是PCP/AP，该PCP/AP基于数据帧进行自发自收感知，即第一帧结构为数据帧。
在一种可能的实现方式中，该PCP/AP可以在第二帧结构的DMG Short Sensing Capability Element字段宣称其具备自发自收感知能力。可选的，该第二帧结构可以是关联申请帧(Association Request Frame)，关联响应帧(Association Response Frame),再关联申请 (Reassociation Request Frame),再关联响应帧(Reassociation Response Frame),DMG Beacon帧，信息请求帧(Information Request Frame)，信息响应帧(Information Response Frame)，数据帧、探测请求帧(Probe Request)，探测响应帧(Probe Response)等帧。具体可选的，该第三信息和第四信息可以包含于DMG Short Sensing Capability Element的Short Sensing Capabilities字段中，具体可以参照第一种可选的实施方式中。
在另一种可能的实现方式中，还可以在DMG信标帧Beacon的Extended Schedule element的对应Allocation field中，采用至少1个bit，指示该Allocation是用于/支持被动感知Passive sensing和自发自收感知monostatic sensing，即第二帧结构为DMG信标帧。如图5d和图5e所示，为Allocation field的两种结构示意图，如图所示，可以采用Allocation Control subfield中的reserved bit承载第三信息和第四信息。可以理解的是，PCP/AP也可以通过DMG Short Sensing Capability Element宣称该PCP/AP支持被动感知Passive sensing，而通过Beacon的Extended Schedule element的对应Allocation field中的bit指示该Allocation支持自发自收感知。

可选的，STA可以在A-BFT过程中发送SSW或者Short SSW，可以使用SSW或者Short SSW的预留比特指示STA支持自发自收感知，或者指示STA具备自发自收感知能力。如图5f所示，为本申请提供的SSW的结构示意图，可以采用该SSW的SSW Feedback字段中的预留比特位指示该STA支持自发自收感知，或指示STA具备自发自收感知能力。如图5g所示，为本申请提供的Short SSW的结构示意图，可以采用该Short SSW中的预留比特位指示 该STA支持自发自收感知，或指示STA具备自发自收感知能力。即通过SSW或者Short SSW中的预留比特位承载或表示第三信息。
在第四种可选的实施方式中，第一设备为STA，该STA基于数据帧进行自发自收感知，即第一帧结构为数据帧。

可选的，STA可以在A-BFT过程中发送SSW帧或者Short SSW帧，可以使用SSW帧或者Short SSW帧的预留比特指示STA支持自发自收感知，或指示STA具备自发自收感知能力。如图5f所示，为本申请提供的SSW的结构示意图，可以采用该SSW的SSW Feedback字段中的预留比特位指示该STA支持自发自收感知，或指示STA具备自发自收感知能力。如图5g所示，为本申请提供的Short SSW的结构示意图，可以采用该Short SSW中的预留比特位指示该STA支持自发自收感知，或指示STA具备自发自收感知能力。
在一种可能的实现方式中，也可以在数据帧中加入至少一个bit来指示该STA支持被动感知Passive sensing和自发自收感知monostatic sensing，或指示STA具备被动感知能力和自发自收感知能力，即第二帧结构为数据帧，比如可以在PHY header或MAC header的任意至少一个reserved bit承载第三信息和第四信息。可以理解的是，STA也可以通过DMG Short Sensing Capability Element宣称该STA支持Passive sensing，而通过数据帧中加入的一个bit来指示该STA支持自发自收感知。
202、第二设备向第一设备发送第一信息和第二信息，该第一信息用于请求第一设备进行自发自收感知，第二信息用于请求获取目标波束信息和目标位置信息，目标波束信息为第一设备发送第一帧结构的波束信息，目标位置信息为第一设备发送第一帧结构的位置信息。相应的，第一设备接收该第一信息和第二信息。
203、第一设备根据第一信息，基于第一帧结构进行自发自收感知，获得第一感知结果。
204、第二设备向第一设备发送第一请求帧，该第一请求帧用于请求获取自发自收感知结果。相应的，第一设备接收该第一请求帧。
205、第一设备向第二设备发送第一响应帧，该第一响应帧包括第一感知结果。相应的，第二设备接收该第一响应帧。
206、第一设备根据第二信息，发送目标波束信息和目标位置信息
207、第二设备根据目标波束信息和目标位置信息，基于第一帧结构进行被动感知。
208、第二设备根据目标波束信息和目标位置信息，解析第一感知结果。
在一些实施例中，第二设备解析第二帧结构中的相关信息，比如第三信息和第四信息，该第二设备通过第三信息确定第一设备支持自发自收感知，该第二设备可以通过第一信息向第一设备请求其进行自发自收感知。第二设备通过第四信息确定第一设备支持被动感知，该 第二设备可以通过第二信息向第一设备请求目标波束信息和目标位置信息，可理解的是，为了便于第二设备解析第一设备的自发自收感知结果，该第二设备也需要向第一设备请求目标波束信息和目标位置信息。
示例性的，第一信息和第二信息可以包含于信息请求information request帧中，例如，第一信息和第二信息分别包含于information request帧的不同元素中，或者，第一信息和第二信息也可以包含于information request帧的被动感知信息元素(例如：DMG Passive Sensing Beacon Info element/DMG Passive Sensing SSW Info element/DMG Passive Sensing Short SSW Info element/DMG Passive Sensing Info element)中，或者，第一信息和所述第二信息可以分别包含于不同请求帧中，比如第二信息包含于information request帧中，而第一信息包含于另一个请求帧中(如DMG Sensing Measurement Setup Request/DMG Sensing Measurement Instance Request/DMG Sensing Request)，本申请不作限定。
具体可选的，第二设备向第一设备发送information request帧，请求第一设备自身的目标位置信息(包括发送第一帧结构时的朝向姿态信息)和第一设备发送第一帧结构的目标波束信息(包括波束水平方向，垂直方向，波束水平宽度，波束垂直宽度，波束增益等信息)，以利用第一设备后续发送的第一帧结构进行被动感知passive sensing。除此之外，第二设备还可以同时请求第一设备后续在发送第一帧结构时利用第一帧结构进行自发自收感知。待感知完成后，第二设备可以向第一设备请求基于第一帧结构的自发自收感知monostatic sensing的第一感知结果，可理解的是，第二设备请求的第一设备自身的目标位置信息和发送第一帧结构的目标波束信息也可以用于解读或解析第一感知结果。
示例性的，以第一设备为AP或PCP，第二设备为STA，第一帧结构为Beacon作为举例进行说明，STA可以通过Information request帧中包含的DMG Passive Sensing Beacon Info element来请求AP发送Beacon的目标波束信息和AP的目标位置信息等信息。AP会向STA发送Information response帧，该Information response帧中包含DMG Passive Sensing Beacon Info element(描述Beacon的发送时间和AP位置等信息)和一或多个DMG Beacon Sector Descriptors elements(描述Beacon发送的波束信息等信息)。
本申请实施例中，用于请求AP进行自发自收感知的第一信息可以包含于Information request帧的DMG Passive Sensing Beacon Info Element中，即DMG Passive Sensing Beacon Info Element额外包含一个指示信息(即第一信息)来请求AP基于Beacon进行自发自收感知。如图5h所示，即是DMG Passive Sensing Beacon Info Element的结构示意图，本申请的第一信息可以包含于Beacon Info Control字段中，当然也可以是包含于DMG Passive Sensing Beacon Info Element的其他字段中。示例性的，如图5i所示，为Beacon Info Control字段的一种可能的结构示意图，在该Beacon Info Control字段中增加一个比特Monostatic Sensing request用于请求AP进行自发自收感知，即Monostatic Sensing request包含第一信息，第一信息承载在Monostatic Sensing request中。示例性的，如图5j所示，为Beacon Info Control字段的另一种可能的结构示意图，与图5i相比，在图5j中，该Beacon Info Control字段包括The Next Beacon字段，该字段用于指示AP后续发送的目标波束信息是用于描述本次BTI中的Beacon或者是下次BTI中的Beacon，可理解，图5j中的比特Monostatic Sensing request也是用于请求AP进行自发自收感知，即Monostatic Sensing request包含第一信息，第一信息承载在Monostatic Sensing request中。
STA通过Information request帧请求了AP关于其自身的目标位置信息和发送Beacon的目标波束的相关信息，并且在该Information request帧中同时请求AP基于Beacon进行自发 自收的感知。
此时，基于AP发送的目标位置信息和发送Beacon的目标波束的相关信息，STA通过AP发送的Beacon进行被动感知，AP在STA请求下基于Beacon进行自发自收的感知。后续STA，可以向AP请求基于Beacon的自发自收感知结果，即第一感知结果，AP通过第一响应帧反馈第一感知结果，STA收到第一感知结果之后联合被动感知结果进行分析。
可选的，用于承载第一信息的monostatic sensing request bit还可以出现在一个新的element之中。即此时的information request帧包含两个element，一个element请求passive sensing相关信息(即DMG Passive Sensing Beacon Info Element)，一个element请求自发自收感知。
需要声明的是，以上请求目标波束信息和目标位置信息与请求AP进行自发自收感知还可以分开两个帧实现，即通过information request/response来交互Beacon的发送波束信息和AP的目标位置信息，STA通过另一个请求帧(如DMG Sensing Measurement Setup Request/DMG Sensing Measurement Instance Request/DMG Sensing Request)请求AP基于Beacon进行自发自收感知，相应的，AP基于该另一个请求帧对应的响应帧反馈自发自收感知结果。可理解，若第一帧结构为BRP，则上述交互流程中的Beacon可被替换为BRP。
类似的，自发自收感知设备为STA，即第一设备为STA，第二设备为AP或PCP，可以采用对应的流程完成相关信息请求反馈的交互。可理解，当自发自收感知设备为STA，Information Request/Response帧中会包含对应的DMG Passive Sensing(SSW/Short SSW/BRP)Info element。对应的，该element中的信息主要用来描述A-BFT中STA发送SSW/Short SSW/BRP的信息。可以在DMG Passive Sensing(SSW/Short SSW/BRP)Info element中增加一比特Monostatic Sensing request用于请求STA进行自发自收感知，该比特可以位于(SSW/Short SSW/BRP)Info Control字段中，或者，也可以是Information Request帧中包括DMG Passive Sensing(SSW/Short SSW/BRP)Info element和另外一个element，该另外一个element包含比特Monostatic Sensing request，用于请求STA进行自发自收感知，或者，还可以是采用Information Request帧请求STA发送SSW/Short SSW/BRP的目标波束信息和STA的目标位置信息，AP通过另一个请求帧(如DMG Sensing Measurement Setup Request/DMG Sensing Measurement Instance Request/DMG Sensing Request)请求STA基于(SSW/Short SSW/BRP)进行自发自收感知。
可以理解的是，如果是PCP/AP或者STA是基于数据帧进行自发自收感知和被动感知，Information Request/Response帧中会包含对应的DMG Passive Sensing(Data PPDU)Info element。对应的，该element中的信息主要用来描述PCP/AP或者STA发送数据帧Data PPDU的相关信息，具体交互流程可以参照前述实施例的描述，在此不再赘述。
第一设备向第二设备发送第一帧结构的目标波束信息和发送第一帧结构时第一设备的目标位置信息，可以被用以同时解读被动感知passive sensing和自发自收感知monostatic sensing的结果。提升了感知效率，并节省了位置信息和波束发送信息交互overhead。并且同时实现了基于同一个Beacon/SSW/Short SSW/数据帧的passive sensing和monostatic sensing，增加了同一个时刻的感知分集增益，相较于独立进行的方式，可以提升感知的性能。
图6是本申请实施例提供的又一种自发自收感知方法的流程示意图。图6中的方法流程为图3中的方法的一种可能的实现方式。如图6所示，该方法包括：
301、第一设备通过第五信息宣称第一设备基于第一帧结构进行自发自收感知。
302、第一设备基于第一帧结构进行自发自收感知，获得第一感知结果。
303、第二设备向第一设备发送第一请求帧，第一请求帧用于请求获取自发自收感知结果。

305、第二设向第一设备发送第二请求帧，第二请求帧用于请求获取目标波束信息和目标位置信息。
306、第一设备向第二设备发送目标波束信息和目标位置信息，所述目标波束信息为所述第一设备发送所述第一帧结构的波束信息，所述目标位置信息为所述第一设备发送所述第一帧结构时的位置信息。

其中，第二设备可以通过第一请求帧向第一设备请求获取自发自收感知结果，该第一设备通过第一响应帧将自发自收感知的第一感知结果发送给第二设备。可选的，该第一请求帧还用于请求获取目标波束信息和目标位置信息，示例性的，该第一请求帧可以是Information Request帧。可选的，第一请求帧可以是用于请求获取自发自收感知结果，第二设备通过第二请求帧请求获取目标波束信息和目标位置信息，示例性的，该第一请求帧可以是DMG Sensing Poll帧，该第二请求帧可以是Information Request帧。进一步，第二设备根据所获取的目标波束信息和目标位置信息对第一设备的第一感知结果进行解析。
在一些可选的方式中，上述第五信息可以包含于第三帧结构中；若第一设备为PCP或AP，该第三帧结构为以下中的一项或多项：关联申请帧，关联响应帧，再关联申请帧，再关联响应帧，DMG信标帧，信息请求帧，信息响应帧、探测请求帧(Probe Request)，探测响应帧(Probe Response)或数据帧等等。若第一设备为STA，第三帧结构为以下中的一项或多项：关联申请帧，关联响应帧，再关联申请帧，再关联响应帧，信息请求帧，信息响应帧，探测请求帧(Probe Request)，探测响应帧(Probe Response)，SSW帧，Short SSW帧或数据帧等等。
