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。在感知测量中，AP和STA中的一者可以作为发送方(transmitter)发送用于感知测量的消息帧(例如，NDP(空数据包：null data packet)帧)，另一者可以作为接收方(receiver)接收用于感知测量的消息帧(例如，NDP帧)，从而完成具体的感知测量事件并获得测量结果。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。将理解，以上描述的WLAN感知的过程仅是示例性的，可以省略其中的一些阶段，或者其中的一些阶段可以被合并或拆分。
此外，在WLAN感知的技术中，提出了基于触发(TB：trigger-based)的感知测量以及非基于触发(Non-TB)的感知测量。在TB感知测量中，AP可以为发起方，例如，在WLAN感知测量建立中，AP可以作为发起方发起感知测量建立，STA作为响应方响应AP发起的感知测量建立。在Non-TB感知测量中，站点(STA)可以为发起方，例如，站点发送空数据包声明(NDPA，Null Data Packet Announcement)帧给AP进行感知测量，为上行或下行感知测量，或二者共存。
在常规的TB感知测量和Non-TB感知测量中，AP或STA作为发起方发起 感知测量，其可以为用于感知测量的消息帧(例如，NDP帧)的发送方或接收方；此外，在AP发起响应方-响应方(responder对responder)的感知测量中，AP可能既不是NDP帧的接收方，也不是NDP帧的发送方，或AP可以作为NDP帧的接收方(与Non-TB感知测量和Non-TB感知测量中的上行感知测量相同)，或AP可能需要接收感知测量报告。然而，目前的WLAN感知测量机制在感知测量建立过程中缺乏相应的信令来进行明确规定。
有鉴于此，根据本公开的实施例的构思提供了一种用于感知测量建立的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设备(AP)。换言之，图2所示的通信方法可以应用于WLAN感知的发起方(AP)。
参照图2，在步骤210中，确定无线帧，其中，无线帧可以包括接入点设备设置的感知测量参数信息。
在本公开的实施例中，确定无线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无线帧：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无线帧，对此本公开实施例不作具体限制。例如，作为非限制性的实施例，可以根据在感知测量建立之前执行的感知测量会话建立过程中交换的、发起方和接收方支持的感知操作参数能力信息来确定无线帧，例如，确定无线帧中的各种感知测量参数信息。
根据本公开的实施例，无线帧可以是各种类型的帧，例如但不限于，无线帧可以是感知测量建立请求帧。换言之，图2所示的通信方法可以是在感知测量建立过程中执行的通信方法。
在步骤220中，可以发送无线帧。例如，发起方AP可以向响应方STA发送步骤210中确定的无线帧，使得响应方STA获得AP设置的感知测量参数信息。
根据本公开的各种实施例，无线帧可以包括AP设置的各种感知测量参数信息。
在本公开的一个实施例中，提供了一种用于感知测量建立的通信方法，感知测量建立请求帧中可以包括第一标识位，其中，第一标识位可以用于标识接入点设备发起响应方-响应方的感知测量建立，其中，发起响应方-响应方的感知测量建立可以指由作为响应方的站点设备发送用于感知测量的消息帧。例如，用于感知测量的消息帧可以是NDP帧，例如，NDP帧可以包括执行WLAN感知测量所需的工作参数，诸如，空间流数量、NDP帧的工作带宽、长训练域(LTF，long training field)、数据包扩展域(PE，packet extension)等。然而，本公开不限于此，携带有执行WLAN感知测量所需的工作参数的其他帧也是可行的。
作为非限制性实施例，AP可以利用至少一个比特位来设置第一标识位，例如，当第一标识位被设置为特定值(例如但不限于“1”)时，第一标识位可以标识AP发起响应方-响应方的感知测量建立。即，AP可以在无线帧(例如，感知测量建立请求帧)中将第一标识位设置为特定值以标识：在AP发起的感知测量建立中，响应方(STA)作为发送方来发送NDP帧以执行具体的感知测量事件。
根据参照图1描述的实施例，在TB感知测量中，由AP作为发起方发起感知测量建立，在本实施例中，AP可以在无线帧(例如，感知测量建立请求帧)中设置第一标识位以标识AP在TB感知测量中进一步发起响应方-响应方的感知测量建立。
在本公开的一个实施例中，提供了一种用于感知测量建立的通信方法，感知测量建立请求帧中可以包括感知接收方标识位，其中，在感知接收方标识位被设置为第一值(例如但不限于“1”)的情况下，标识接入点设备作为接收方接收用于感知测量的消息帧(例如，NDP帧)。也就是说，AP可以在无线帧(例如，感知测量建立请求帧)中设置感知接收方标识位，以标识在发起的感知测量建立中AP可以接收其中的一个响应方(STA)发送的NDP帧。
在本公开的一个实施例中，提供了一种用于感知测量建立的通信方法，感知测量建立请求帧中可以包括感知测量报告标识位。感知测量报告标识 位用于标识AP是否接收感知测量结果的报告。例如，在感知测量报告标识位被设置为第二值(例如但不限于“1”)的情况下，标识接入点设备接收感知测量报告；在感知测量报告标识位被设置为第三值(例如但不限于“0”)的情况下，标识接入点设备不接收感知测量报告。例如，当AP在无线帧(例如，感知测量建立请求帧)中将感知测量报告标识位设置为AP接收感知测量报告时，标识AP可以接收响应方-响应方的NDP感知测量报告，并且在感知测量报告过程中，可以由AP发起感知测量报告请求帧或由响应方直接发起感知测量报告，从而AP可以获得感知测量结果。
在本公开的一个实施例中，提供了一种用于感知测量建立的通信方法，感知测量建立请求帧中可以包括第二标识位，其中，第二标识位用于标识站点设备在感知测量过程中为发送方或者接收方。站点设备(STA)可以是与AP进行感知测量建立的响应方，AP可以在无线帧(例如，感知测量建立请求帧)中利用第二标识位来标识STA是用于感知测量的消息帧(例如，NDP帧)的发送方还是接收方。
例如，第二标识位可以具有一个或更多个比特位，以用于标识一个或更多个STA是NDP帧的发送方还是接收方。在一个感知测量过程(或称为感知测量事件)中，可以仅存在一个NDP帧的发送方，但可以存在一个或更多个NDP帧的接收方。
作为一个可选择的实施例，感知测量建立请求帧还可以包括STA的标识符，例如，可以利用AID或UID来标识STA。AID可以表示与AP建立关联通信的STA的标识符，UID可以表示与AP未建立关联通信的STA的标识符。此外，可选择地，STA的标识符AID或UID可以被包括在第二标识位中，例如，可以利用第二标识位的部分比特位来标识AID或UID，并且利用第二标识位的另一部分比特位来标识相应STA是NDP帧的发送方还是接收方。然而本公开不限于此，STA的标识符AID或UID可以在无线帧(例如，感知测量建立请求帧)中与第二标识位分开标识，但是可以与第二标识位一一对应。
在本公开的一个实施例中，提供了一种用于感知测量建立的通信方法， 感知测量建立请求帧中可以包括感知测量建立标识符。感知测量建立标识符用于标识AP发起的感知测量建立过程。可选择地，AP可以标识在与感知测量建立标识符对应的感知测量建立过程中，STA是作为发送方还是接收方参与感知测量。例如，在站点设备为发送方的情况下，标识在与感知测量建立标识符对应的感知测量事件中，站点设备发送用于感知测量的消息帧(例如，NDP帧)；例如，在站点设备为接收方的情况下，标识在与感知测量建立标识符对应的感知测量事件中，站点设备接收用于感知测量的消息帧(例如，NDP帧)。
在上述各实施例中，分别单独地描述了无线帧(例如，感知测量建立请求帧)中包括的AP设置的各种感知测量参数信息。将理解，可以对上述各实施例中的内容进行各种组合。此外，上述各实施例中的内容仅是示例性的，无线帧还可以包括其他各种信息。
例如，在本公开提供的一种用于感知测量建立的通信方法中，AP设置的各种感知测量参数信息可以以感知测量参数信息元素(Sensing Measurement Parameters element)的格式被包括在无线帧(例如，感知测量建立请求帧)中。作为非限制性的实施例，感知测量参数信息元素的格式可以如下面的表1所示。
表1.感知测量参数信息元素的格式
Figure PCTCN2022091201-appb-000001
在表1中，元素标识(Element ID)可以标识感知测量参数信息元素，长度(Length)可以标识感知测量参数信息元素的长度，元素标识扩展(Element ID Extension)可以标识感知测量参数信息元素的扩展。
此外，STA发送方/接收方(STA receiver/transmitter)可以对应于参照上文的实施例描述的第二标识位，用于标识STA在感知测量过程中为发送方或者接收方。感知测量建立标识符(Sensing Measurement setup ID)可以对应于参照上文的实施例描述的感知测量建立标识符。虽然在表1中 仅示出了一个STA发送方/接收方(STA receiver/transmitter)和一个感知测量建立标识符(Sensing Measurement setup ID)，但是本公开不限于此，可以在表1中包括更多个STA发送方/接收方(STA receiver/transmitter)和更多个感知测量建立标识符(Sensing Measurement setup ID)。
此外，表1中的感知测量参数域(Sensing Measurement Parameters)可以具有如下面的表2所示的格式。
表2.感知测量参数域的格式
Figure PCTCN2022091201-appb-000002
表2中的感知发送方(Sensing Transmitter)可以标识AP是否作为发送方来发送用于感知测量的消息帧(例如，NDP帧)。例如，当感知发送方(Sensing transmitter)被设置为特定值(例如但不限于“1”)时，AP在发起的感知测量建立中可以作为发送方来发送NDP帧；当感知发送方(Sensing transmitter)被设置为另一特定值(例如但不限于“0”)时，AP在发起的感知测量建立中不作为发送方来发送NDP帧。
表2中的感知接收方(Sensing Receiver)可以对应于参照上文的实施例描述的感知接收方标识位，用于标识AP是否作为接收方接收用于感知测量的消息帧(例如，NDP帧)。例如，当感知接收方(Sensing Receiver)被设置为特定值(例如但不限于“1”)时，AP在发起的感知测量建立中可以作为接收方来接收NDP帧；当感知接收方(Sensing Receiver)被设置为另一特定值(例如但不限于“0”或者保留位)时，AP在发起的感知测量建立中不作为接收方来接收NDP帧。
表2中的测量报告类型(Measurement Report Type)可以用于标识感知测量事件的测量结果的类型。例如但不限于，测量报告类型(Measurement Report Type)可以被设置为信道状态信息(CSI，channel state information)，即，AP可以接收CSI作为测量结果。如果AP是作为NDP帧的接收方参与感知测量事件，则测量报告类型(Measurement Report Type)可以被设置为保留位。
表2中的响应方-响应方感知测量建立(Responder to Responder Measurement Setup)可以对应于参照上文的实施例描述的第一标识位，用于标识AP是否发起响应方-响应方的感知测量建立。例如，当响应方-响应方 感知测量建立(Responder to Responder Measurement Setup)被设置为例如但不限于“1”时，可以标识AP发起响应方-响应方的感知测量建立；当响应方-响应方感知测量建立(Responder to Responder Measurement Setup)被设置为例如但不限于“0”时，可以标识AP不发起响应方-响应方的感知测量建立。
表2中的感知测量报告(Measurement Report)可以对应于参照上文的实施例描述的感知测量报告标识位，用于标识AP是否从响应方STA接收感知测量报告。例如，当感知测量报告(Measurement Report)被设置为例如但不限于“1”时，AP接收感知测量报告；当感知测量报告(Measurement Report)被设置为例如但不限于“0”时，AP不接收感知测量报告。
虽然参照表1和表2描述了无线帧(例如，感知测量建立请求帧)可以包括的各种感知测量参数信息，但是并不表示无线帧(例如，感知测量建立请求帧)必须包括表1和表2中所示的全部内容。例如，AP可以根据例如AP和STA的硬件能力等信息省略其中的部分内容，或者还可以包括更多其他内容。
根据本公开的实施例，AP在感知测量建立过程中发送感知测量建立请求帧给STA，其中，STA为响应方。在感知测量建立请求帧中，可以携带至少一个标识位，标识AP发起responder对responder的测量事件建立过程，例如，AP可以设置其感知测量参数信息域(例如，表2)中的“Sensing Receiver”比特位为“1”，标识AP在测量事件中接收其中的一个响应方(STA)发送的NDP帧。
根据本公开的实施例，AP在感知测量参数信息域(例如，表2)中将另一个比特位(例如，感知测量报告标识位(Measurement Report))设置为“1”，标识AP可以接收responder对responder中的NDP感知测量报告，其中，可以由AP发起感知测量报告请求帧或由响应方直接发起感知测量报告；设置为“0”，标识其不接收感知测量报告。
根据本公开的实施例，AP在感知测量建立请求帧中可能还包括其他的标识位，例如，第二标识位(表1中的STA receiver/transmitter)，用于标识与AP建立感知测量过程的STA在responder对responder感知测量过程中为 NDP帧的发送方或接收方，如果STA为发送方，则STA在与测量建立标识符对应的感知测量事件中发送NDP帧，如果STA为接收方，则STA在与测量建立标识符对应的的感知测量事件中接收NDP帧。根据本公开的实施例，在一个感知测量事件中，即，与一个感知建立标识对应的感知测量中，可以只存在一个responder对responder感知测量NDP帧的发送方，但是可以存在多个NDP帧的接收方。
图3是示出根据示例实施例的另一通信方法的流程图。图3所示的通信方法可以应用于站点设备(STA)。
参照图3，在步骤310中，STA从接入点设备(AP)接收无线帧，其中，无线帧可以包括接入点设备设置的感知测量参数信息。
可选择地，无线帧可以为感知测量建立请求帧。
可选择地，无线帧可以包括第一标识位，其中，第一标识位用于标识接入点设备发起响应方-响应方的感知测量建立。发起响应方-响应方的感知测量建立可以指由作为响应方的站点设备发送用于感知测量的消息帧(例如，NDP帧)。由于AP可能在无线帧中携带关于多个站点设备的参数信息，因此，发起的响应方-响应方的感知测量建立中的“作为响应方的站点设备”可以是接收到无线帧的站点设备(即，执行图3所示的通信方法的STA)，也可以是除接收到无线帧的站点设备外的其他站点设备。
可选择地，无线帧可以包括感知接收方标识位，其中，在感知接收方标识位被设置为第一值的情况下，标识接入点设备作为接收方接收用于感知测量的消息帧(例如，NDP帧)。
可选择地，无线帧可以包括感知测量报告标识位，其中，在感知测量报告标识位被设置为第二值的情况下，标识接入点设备接收感知测量报告；在感知测量报告标识位被设置为第三值的情况下，标识接入点设备不接收感知测量报告。
可选择地，无线帧可以包括第二标识位，其中，第二标识位用于标识站点设备在感知测量过程中为发送方或者接收方。由于AP可能在无线帧中携带关于多个站点设备的参数信息，因此，无线帧可以包括多个第二标识位，除了标识接收到无线帧的站点设备(即，执行图3所示的通信方法 的STA)是作为发送方还是接收方之外，还可以标识其他站点设备是作为发送方还是接收方。
可选择地，无线帧可以包括感知测量建立标识符。例如，在站点设备为发送方(例如，第二标识位标识站点设备为发送方)的情况下，标识在与感知测量建立标识符对应的感知测量事件中，站点设备发送用于感知测量的消息帧。例如，在站点设备为接收方(例如，第二标识位标识站点设备为发送方)的情况下，标识在与感知测量建立标识符对应的感知测量事件中，站点设备接收用于感知测量的消息帧。
上文已经参照各种实施例以及表1和表2具体描述了无线帧、感知测量参数信息、第一标识位、感知接收方标识位、感知测量报告标识位、第二标识位、感知测量建立标识符，因此为了简明，在此省略重复的描述。
在步骤320中，STA基于无线帧发送响应帧。可选择地，当STA接收到的无线帧为感知测量建立请求帧时，STA发送的响应帧可以是感知测量建立响应帧。例如，STA可以解析无线帧，以获得由AP设置的感知测量参数信息，并且可以在回复的响应帧中标识是否接受这样的感知测量参数信息。当STA接受无线帧中的感知测量参数信息时，可以在响应帧中直接标识“接受”；当STA不接受无线帧中的感知测量参数信息时，可以在响应帧中以例如表1和表2的方式来标识STA可支持的感知测量参数信息。这样，AP和STA可以在感知测量建立过程中进行感知测量参数信息的协商，完成满足各种需求的感知测量建立。
根据本公开的实施例的通信方法完善了感知会话建立过程中的信令机制(例如，完善了AP发起响应方-响应方的感知测量建立的信令格式)，使之能够适用于WLAN感知测量。
图4是示出根据示例实施例的通信装置的框图。图4的通信装置400可以包括处理模块410和收发模块420。在本公开的一个实施例，图4所示的通信装置400可以应用于接入点设备；在本公开的另一实施例中，图4所示的通信装置400可以应用于站点设备。
在图4所示的通信装置400可以应用于接入点设备的情况下，处理模块410可以被配置为：确定无线帧，其中，无线帧包括接入点设备设置的感 知测量参数信息；收发模块420可以被配置为：发送无线帧。也就是说，图4所示的通信装置400可以执行参照图2描述的通信方法。此外，上文参照各种实施例以及表1和表2具体描述的无线帧、感知测量参数信息、第一标识位、感知接收方标识位、感知测量报告标识位、第二标识位、感知测量建立标识符等内容可以应用于此，为了避免冗余，在此省略重复的描述。
在图4所示的通信装置400可以应用于站点设备的情况下，收发模块420可以被配置为：从接入点设备接收无线帧，其中，无线帧包括接入点设备设置的感知测量参数信息；处理模块410可以被配置为：基于无线帧控制响应帧的发送。也就是说，图4所示的通信装置400可以执行参照图3描述的通信方法。此外，上文参照各种实施例以及表1和表2具体描述的无线帧、感知测量参数信息、第一标识位、感知接收方标识位、感知测量报告标识位、第二标识位、感知测量建立标识符等内容可以应用于此，为了避免冗余，在此省略重复的描述。
将理解，图4所示的通信装置400仅是示例性的，本公开的实施例不限于此，例如，通信装置400还可以包括其他模块，例如，存储器模块等。此外，通信装置400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。

应该理解的是，虽然附图的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，其可以以其他的顺序执行。此外，附图的流程图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，其执行顺序也不必然是依次进行，而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
