具体实施方式
提供以下参照附图的描述，以帮助全面理解由所附权利要求及其等同物 限定的本公开的各种实施例。本公开的各种实施例包括各种具体细节，但是这些具体细节仅被认为是示例性的。此外，为了清楚和简洁，可以省略对公知的技术、功能和构造的描述。
在本公开中使用的术语和词语不限于书面含义，而是仅被发明人所使用，以能够清楚和一致的理解本公开。因此，对于本领域技术人员而言，提供本公开的各种实施例的描述仅是为了说明的目的，而不是为了限制的目的。
应当理解，除非上下文另外清楚地指出，否则这里使用的单数形式“一”、“一个”、“所述”和“该”也可以包括复数形式。应该进一步理解的是，本公开中使用的措辞“包括”是指存在所描述的特征、整数、步骤、操作、元件和/或组件，但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。
将理解的是，尽管术语“第一”、“第二”等在本文中可以用于描述各种元素，但是这些元素不应受这些术语的限制。这些术语仅用于将一个元素与另一个元素区分开。因此，在不脱离示例实施例的教导的情况下，下面讨论的第一元素可以被称为第二元素。
应该理解，当元件被称为“连接”或“耦接”到另一元件时，它可以直接连接或耦接到其他元件，或者也可以存在中间元件。此外，这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的术语“和/或”或者表述“……中的至少一个/至少一者”包括一个或多个相关列出的项目的任何和所有组合。
除非另外定义，这里使用的所有术语(包括技术术语和科学术语)，具有与本公开所属领域中的普通技术人员的一般理解相同的意义。
图1是示出WLAN感知的示例性方式。
WLAN感知的流程可以是：发起方(initiator)发起WLAN感知(例如，发起WLAN感知会话)，可能存在着多个响应方(responder)对其进行响应，具体的可能方式可以如图1中的(a)、(b)和(c)所示。
参照图1中的(a)，当WLAN感知发起方(例如，客户端(client))发起WLAN感知时，多个关联或者非关联的WLAN感知响应方(例如，三个接入点(AP，access point))可以进行响应。这里的“关联”可以指发起方与响应方之间建立了用于通信的关联连接，“非关联”可以指发起方与响应方之 间未建立用于通信的关联连接。
作为示例，客户端(client)可以包括但不限于：蜂窝电话、智能电话、可穿戴设备、计算机、个人数字助理(PDA)、个人通信系统(PCS)设备、个人信息管理器(PIM)、个人导航设备(PND)、全球定位系统、多媒体设备、物联网(IoT)设备等。
AP可以是用于无线网络的无线交换机，也可以是无线网络的接入设备。AP可以包括软件应用和/或电路，以使无线网络中的其他类型节点可以通过AP与无线网络外部及内部进行通信。作为示例，AP可以是配备有Wi-Fi(Wireless Fidelity，无线保真)芯片的终端设备或网络设备。
图1中的(b)与图1中的(a)相似，但是在图1中的(b)中，各个响应方(AP)之间可以进行通信。
参照图1中的(c)，WLAN感知发起方和WLAN感知的响应方均可以是客户端，并且二者可以通过连接到同一AP进行通信。
虽然在图1中的(a)、(b)和(c)中示出了，客户端作为发起方，AP作为响应方，然而本公开不限于此。例如，在本公开的各种实施例中，AP可以作为发起方，客户端可以作为响应方。此外，在本公开的各种实施例中，客户端也可以被称为非AP的站点(non-AP STA)，简称为“站点(STA)”。此外，发起方和响应方的数目不受限于图1中的(a)、(b)和(c)所示。
作为说明性的实施例，WLAN感知的过程可以包括：WLAN感知会话(session)建立、WLAN感知测量建立以及WLAN感知测量终止。在WLAN感知会话建立中，与感知会话相关联的操作参数可以被确定，并在设备之间进行交换。在WLAN感知测量建立中，可以执行感知测量和/或测量结果的报告，因此WLAN感知测量建立也可以被称为WLAN感知测量过程。在WLAN感知测量终止中，设备停止执行测量并且终止感知会话。
此外，在WLAN感知的技术中，提出了基于触发(TB-based)的感知方式以及非基于触发(Non-TB based)的感知方式。例如，TB-based的感知方式是基于空数据包声明(NDPA，Null Data Packet Announcement)帧及触发帧(trigger)触发的形式，AP作为发起方；Non-TB based的感知方式是基于NDPA的形式，站点(STA)作为发起方。此外，TB-based的感知方式以及Non-TB based的感知方式均以空数据包(NDP，Null Data Packet)帧作为感知测量帧参与感知测量。
在TB-based的场景中，NDP帧均是参与感知测量的感知测量帧。在Non-TB based的场景中，可能为了维护协议完成性，在上行感知测量(UL sounding)或下行感知测量(DL sounding)中会发送不参与感知测量的UL NDP帧或DL NDP帧。
在目前的研究中，NDP帧中的长训练域(LTF，long training field)主要用于信道的测量，在感知测量过程中也会重用LTF来进行感知测量。然而，目前对于Non-TB based的感知方式及TB-based的感知方式，缺乏关于NDP帧中的LTF的明确规定，所以需要进行信令的增强。
有鉴于此，根据本公开的实施例的构思提供了一种通信方法和通信装置。
图2是示出根据示例实施例的通信方法的流程图。图2所示的通信方法可以应用于接入点(AP)，也可以应用于非接入点的站点(简称为：站点“STA”)。
参照图2，在步骤210中，确定第一消息帧，其中，第一消息帧可以包括第一子域，其中，第一子域用于标识第二消息帧中的长训练域(LTF)的信息，其中，长训练域用于信道的测量；在步骤220中，发送第一消息帧。
在本公开的实施例中，确定第一消息帧的方式可以有很多种，例如：可以根据以下的至少一种情况来生成或配置第一消息帧：信道状态、网络情况、负载情况、发送/接收设备的硬件能力、业务类型、相关协议规定；对此本公开实施例不作具体限制。在本公开的实施例中，还可以从外部设备获取该第一消息帧，对此本公开实施例不作具体限制。
在本公开的实施例中，第一消息帧可以是NDPA帧或感知测量触发帧(在下文也可以简称为“触发帧”)。第二消息帧可以携带有长训练域，例如，在下文中，为了描述的方便，以NDP帧作为第二消息帧的示例，然而，本公开不限于此，其他携带LTF的帧也是可行的。下面的表1和表2示出了仅作为示例性的两种NDP帧的格式。
表1：HE探测(sounding)NDP帧格式
Figure PCTCN2022087170-appb-000001
表2：HE测距(Ranging)NDP帧格式
Figure PCTCN2022087170-appb-000002
表1示出了HE(高效，High Efficiency)探测NDP帧格式，表2示出了HE测距NDP帧格式。表1中的“HE-LTF”和表2中的“HE-LTF 1”至“HE-LTF n”可以指上述实施例中的第二消息帧中的长训练域。此外，参照表1和表2，NDP帧还可以包括：传统短训练域(L-STF)、传统长训练域(L-LTF)、传统信令域(L-SIG)、重复传统信令域(RL-SIG)、HE信令域(HE-SIG-A)和HE短训练域(HE-STF)、以及数据包扩展域(PE，packet extension)等，然而，这仅是示例性的，本公开不限于此。
将理解，虽然在上述表1和表2中指出了可用的NDP帧的格式，然而者仅是示例性的，本公开不限于此，例如，EHT(极高吞吐量，Extreme High-Throughput)探测NDP帧等也适用于本公开的各种示例实施例。
根据本公开的实施例，第一消息帧中的第一子域可以是长训练域重复(LTF repetition)子域，其用于标识第二消息帧中的LTF的数量。换言之，可以在第一消息帧(NDPA帧或感知测量触发帧)中标识第二消息帧(NDP帧)中的LTF(如表1中的“HE-LTF”和表2中的“HE-LTF 1”至“HE-LTF n”)的信息(例如，LTF的数量)。第一子域(即，LTF repetition子域)能够增加信噪比(SNR)，这对于感知测量应用是非常重要的。此外，预先在第一消息帧中标识出第二消息帧中的LTF的信息(例如，LTF的数量)有利于在感知测量过程中保证信令的安全接收和正确解析，例如，保证LTF的安全，从而能够在信道估计中进行一致性检查，以检测安全攻击。
在本公开的实施例中，可以基于感知方式(TB-based或Non-TB based)或者第二消息帧(NDP帧)是否参与感知测量，来设置/确定第一子域的值(即， LTF的数量)。
根据本公开的实施例，第一消息帧(NDPA帧或感知测量触发帧)可以包括第二子域，其中，第二子域可以用于标识第一子域要应用于的设备的标识符，并且，第二子域可以与第一子域相对应。例如，第一消息帧中可以包括一个或更多个第一子域及其各自对应的第二子域，从而可以标识一个或更多个设备的第二消息帧中的LTF的信息。
例如，在第一子域要应用于站点(STA)的情况下，该标识符可以标识站点(STA)，例如，该标识符可以为AID或UID。AID可以表示与AP建立了关联通信的站点的标识符，UID表示与AP未建立关联通信的站点的标识符。例如，在第一子域要应用于接入点(AP)的情况下，该标识符可以标识接入点(AP)，例如，该标识符可以为特殊AID，例如但不限于，利用值为0的特殊AID来标识AP。
此外，在一个可选择的实施例中，第一消息帧(NDPA帧或感知测量触发帧)可以包括站点信息(STA info)域，上述的第一子域和第二子域可以包括在站点信息域中。例如，在站点信息域中可以包含LTF重复(LTF repetition)子域，其标识在感知测量中NDP帧包含的LTF的数量。此外，LTF repetition子域可以与STA的标识符对应，其中，标识符可以为AID(建立关联)或UID(未建立关联)。例如，在Non-TB based的感知测量中，则对应的站点信息域可能用于AP，则AID可能为特殊的AID，例如为0。
根据本公开的实施例的通信方法，完善了在感知测量过程中对LTF数量的定义，使之适应WLAN感知测量的需求。
图3是示出根据示例实施例的TB-based的感知方式下的流程图。
根据本公开的实施例，在基于触发的感知测量过程中(即，在TB-based的感知方式中)，第二消息帧(例如，NDP帧)可以参与感知测量并且第一消息帧(例如，NDPA帧或感知测量触发帧)可以标识第二消息帧中的LTF的数量至少为1。
在TB-based的感知方式中，WLAN感知测量过程可以包括轮询、测量以及反馈三个环节。在轮询环节，发起方(AP)可以发送轮询(poll)帧以检查响应方(一个或更多个STA)的可用性；如果STA可用，其可以报告响应帧(例如，CTS-to-self)。在测量环节中可以采用NDPA探测方式(在下文可以称为 “NDPA sounding”或“NDPA探测”)和/或TF(触发帧，trigger frame)探测方式(在下文可以称为“TF sounding”或“TF探测”)。在反馈环节中，可以反馈感知测量结果，例如，信道状态信息(CSI，channel state information)。图3的(a)示出了NDPA探测的流程图，图3的(b)示出了TF探测的流程图。
参照图3的(a)，在NDPA探测的情况下，发起方(AP)可以向响应方(STA)发送NDPA帧以及NDP帧，其中，NDPA帧可以对应于上述实施例中的第一消息帧，NDP帧可以对应于上述实施例中的第二消息帧。NDPA帧可以标识NDP帧中的LTF的数量。响应方(STA)可以接收NDPA帧和NDP帧，并且利用NDP帧进行WLAN感知测量，然后向发起方(AP)报告感知测量结果(例如，CSI)。例如，响应方(STA)可以解析NDPA帧获知所标识的NDP帧中的LTF的数量，并且可以解析NDP帧，检查接收到的NDP帧中的LTF的数量是否与NDPA帧中所标识的数量相同。这里，NDP帧可以参与感知测量，因此，NDPA帧中所标识的数量可以被设置为至少为1。
在一个可选择的实施例中，在图3的(a)中，NDPA帧还可以包括发起方(AP)的标识符(例如，特殊AID)，以标识NDPA帧中所标识的LTF的数量应用于AP(例如，应用于AP发送的NDP帧)。
参照图3的(b)，在TF探测的情况下，发起方(AP)可以向响应方(STA)发送触发帧(即，感知测量触发帧)，然后响应方(STA)可以向发起方(AP)发送NDP帧，从而发起方(AP)可以利用NDP帧进行WLAN感知测量。触发帧(即，感知测量触发帧)可以对应于上述实施例中的第一消息帧，NDP帧可以对应于上述实施例中的第二消息帧。触发帧(即，感知测量触发帧)可以标识NDP帧中的LTF的数量。响应方(STA)可以解析触发帧(即，感知测量触发帧)获知所标识的NDP帧中的LTF的数量，并且可以将所标识数量的LTF包括在NDP帧中，发起方(AP)可以在接收到NDP帧时检查NDP帧中的LTF的数量是否与NDPA帧的第一子域所标识的数量相同。这里，NDP帧可以参与感知测量，因此，NDPA帧中所标识的数量可以被设置为至少为1。
在一个可选择的实施例中，在图3的(b)中，触发帧(即，感知测量触发帧)还可以包括响应方(STA)的标识符(AID或UID)，以标识NDPA帧中所标识的LTF的数量应用于STA(例如，应用于STA发送的NDP帧)。
虽然在图3的(a)和(b)中仅示出了一个响应方(STA)，然而，本公开不限于此，可以存在一个或更多个响应方(STA)。在此情况下，针对一个或 更多个响应方(STA)中的每一者，在NDPA帧或触发帧中，分别标识NDP帧中的LTF的数量以及所标识的LTF的数量所应用于的设备的标识符。
例如，在参照图3的(a)和(b)描述的TB-based感知测量流程中，不管是在NDPA帧还是在触发帧中可以至少包含一个站点信息域，其中，站点信息域可以包含LTF重复(LTF repetition)子域，其设置的数量可以至少为1，以标识后续参与感知测量的NDP帧中的LTF的数量。
图4是示出根据示例实施例的Non-TB based的感知方式下的流程图。
根据本公开的实施例，在非基于触发的感知测量过程中(即，在Non-TB based的感知方式中)，在第二消息帧(例如，NDP帧)参与感知测量的情况下，第一消息帧(例如，NDPA帧)可以标识第二消息帧中的LTF的数量至少为1；在第二消息帧(例如，NDP帧)不参与感知测量的情况下，第一子域(例如，NDPA帧)可以标识第二消息帧中的LTF的数量为1。然而，本公开不限于此，可以根据第二消息帧是否参与感知测量将第一消息帧中所标识的LTF的数量设置为不同的值，例如，参与感知测量的情况下的所标识的LTF的数量可以被设置为大于不参与参照测量的情况下的所标识的LTF的数量。
在Non-TB based的感知方式中，站点(STA)发送NDPA帧给AP进行感知测量过程。例如，在Non-TB based的感知方式中，WLAN感知测量过程可以包括上行感知测量(也可以称为上行探测“UL sounding”)或下行感知测量(也可以称为下行探测“DL sounding”)，或二者共存。图4的(a)示出了上行探测的流程图，图4的(b)示出了下行探测的流程图。
参照图4的(a)，上行探测可以包括：发起方(STA)向响应方(AP)发送NDPA帧和NDP帧(示出为“UL NDP”)，AP利用UL NDP执行WLAN感知测量。此外，AP在从STA接收到NDP帧之后，也会发送NDP帧(示出为“DL NDP”)，但是该NDP帧(DL NDP帧)不用于WLAN感知测量，而仅是为了标识其从STA接收到NDPA帧和NDP帧。这里，NDPA帧可以对应于上述实施例中的第一消息帧，UL NDP和DL NDP可以对应于上述实施例中的第二消息帧。在上行探测中，发起方(STA)发送的UL NDP参与感知测量，因此，针对发起方(STA)，NDPA帧中的所标识的LTF的数量可以被设置为至少为1；然而，响应方(AP)发送的DL NDP不参与感知测量，因此，针对响应方(AP)，NDPA帧中所标识的LTF的数量可以被设置 为1。
在一个可选择的实施例中，在图4的(a)中，NDPA帧可以包括关于STA的站点信息域以及关于AP的站点信息域，其中，关于STA的站点信息域可以包括：UL NDP中的LTF数量以及STA的标识符(例如，AID或UID)；关于AP的站点信息域可以包括：DL NDP中的LTF数量以及AP的标识符(例如，特殊AID)。
参照图4的(b)，下行探测可以包括：发起方(STA)向响应方(AP)发送NDPA帧和NDP帧(示出为“UL NDP”)，AP向STA发送NDP帧(示出为“DL NDP”)，从而STA利用接收到的NDP帧进行WLAN感知测量，但是STA发送的NDP帧(UL NDP)不用于WLAN感知测量，而仅是为了协议的完整性的目的。这里，NDPA帧可以对应于上述实施例中的第一消息帧，UL NDP和DL NDP可以对应于上述实施例中的第二消息帧。在下行探测中，发起方(STA)发送的UL NDP不参与感知测量，因此，针对发起方(STA)，NDPA帧中所标识的LTF的数量可以被设置为1；然而，响应方(AP)发送的DL NDP参与感知测量，因此，针对响应方(AP)，NDPA帧中所标识的LTF的数量可以被设置为至少为1。
在一个可选择的实施例中，NDPA帧可以包括关于STA的站点信息域以及关于AP的站点信息域，其中，关于STA的站点信息域可以包括：UL NDP中的LTF数量以及STA的标识符(例如，AID或UID)；关于AP的站点信息域可以包括：DL NDP中的LTF数量的信息以及AP的标识符(例如，特殊AID)。
例如，在参照图4的(a)和(b)的Non-TB based的感知流程中，如果NDP帧参与感知测量，则NDPA帧的站点信息域中的LTF重复(LTF repetition)子域所标识的数量可以被设置为至少为1；如果NDP帧不参与感知测量，则NDPA帧的站点信息域中的LTF重复(LTF repetition)子域所标识的数量可以被设置为1。
根据本公开的实施例，NDP帧的LTF数量(例如，LTF重复(LTF repetition)子域)可以被包括在NDPA帧(Non-TB based或TB-based)或感知测量触发帧(TB-based)中，从而可以为参与测量的STA或AP分配感知测量资源，而不是被包括在轮询帧或感知测量报告帧。这样可以在NDPA帧或感知测量触发帧中明确地标识随后传输的NDP帧中的LTF的数量，有助于信令的安 全接收和正确解析。
根据本公开的实施例的通信方法，完善了在Non-TB based的感知方式及TB-based的感知方式下对LTF数量的定义，使之适应WLAN感知测量的需求。
图5是示出根据示例实施例的另一通信方法的流程图。图5所示的通信方法可以应用于接入点(AP)，也可以应用于非接入点的站点(简称为：站点“STA”)。
参照图5，在步骤510中，可以接收第一消息帧，其中，第一消息帧可以包括第一子域，其中，第一子域用于标识第二消息帧中的长训练域的信息，其中，长训练域用于信道的测量；在步骤520中，可以解析第一消息帧，更具体地，可以基于第一消息帧获得第二消息帧中的长训练域的信息。
根据本公开的实施例，第一消息帧可以为NDPA帧或者感知测量触发帧。
根据本公开的实施例，第二消息帧可以为NDP帧。
根据本公开的实施例，第一子域可以为长训练域重复子域，用于标识第二消息帧中的长训练域的数量。
根据本公开的实施例，第一消息帧可以包括第二子域，其中，第二子域用于标识第一子域要应用于的设备的标识符，其中，第二子域与第一子域相对应。
根据本公开的实施例，在基于触发的感知测量过程中，第二消息帧可以参与感知测量并且第一子域所标识的数量可以被设置为至少为1。
根据本公开的实施例，在非基于触发的感知测量过程中，在第二消息帧参与感知测量的情况下，第一子域所标识的数量可以被设置为至少为1；在第二消息帧不参与感知测量的情况下，第一子域所标识的数量可以被设置为1。
关于第一消息帧、第二消息帧、NDPA帧、感知测量触发帧、第一子域、第二子域等的描述可以类似于上文各种实施例中的描述，为了简明，在此省略重复的描述。

在图6所示的通信装置600可以应用于发送第一消息帧的设备(AP或者STA)，在此情况下，处理模块610可以被配置为：确定第一消息帧，其中，第一消息帧可以包括第一子域，其中，第一子域用于标识第二消息帧中的长训练域的信息，其中，长训练域用于信道的测量；收发模块620可以被配置为：发送第一消息帧。也就是说，图6所示的通信装置600可以执行参照图2描述的通信方法以及图3和图4中由发送NDPA帧或触发帧的设备执行的操作，并且参照表1和表2等描述的实施例可以应用于此，为了避免冗余，在此省略重复的描述。
在图6所示的通信装置600可以应用于接收第一消息帧的情况下，收发模块620可以被配置为：接收第一消息帧，其中，第一消息帧包括第一子域，其中，第一子域用于标识第二消息帧中的长训练域的信息，其中，长训练域用于信道的测量；处理模块610可以被配置为：基于第一消息帧获得第二消息帧中的长训练域的信息。也就是说，图6所示的通信装置600可以执行参照图5描述的通信方法图3和图4中由接收NDPA帧或触发帧的设备执行的操作，并且参照表1和表2描述的实施例可以应用于此，为了避免冗余，在此省略重复的描述。
将理解，图6所示的通信装置600仅是示例性的，本公开的实施例不限于此，例如，通信装置600还可以包括其他模块，例如，存储器模块等。此外，通信装置600中的各个模块可以组合成更复杂的模块，或者可以划分为更多单独的模块。
