具体实施方式

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。
在WLAN感知中，可以存在着感知会话(sensing session)建立以及感知测量建立两个阶段。感知会话是参与WLAN感知过程的感知发起方与感知响应方之间的协议。在WLAN感知过程的感知会话建立中，感知会话被建立，并且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。在感知测量建立中，可以执行感知测量和/或测量结果的报告。
不同的感知测量可能存在着不同的感知测量需求，感知会话建立的过程就是发起方和响应方感知操作参数能力信息交互的过程，从而在感知测量建立中基于交互的感知操作参数能力信息来建立满足不同的需求的感知测量。然而，在现有的标准中，对于设备支持何种感知操作参数能力以及以何种信令去标识感知操作参数能力信息，并没有定义，需加以增强。
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会话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用于感知会话建立的通信方法的流程图。图2所示的通信方法可以应用于WLAN感知的发起方或响应方，即，图2所示的通信方法可以由发起方或响应方来执行。
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 括执行通信方法的设备支持的感知操作参数能力信息。
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、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。
根据本公开的实施例，第一消息帧可以包括以下至少一项：
设备支持的带宽信息；
设备支持的空间流数量信息；
设备支持的调制与编码策略信息；
设备支持的接收和发送的能力信息。
下面分别在各个实施例中描述第一消息帧中所包括的各种信息。
在本公开的一个实施例中，设备支持的带宽信息可以包括：设备支持的用于感知测量的最小带宽信息和/或最大带宽信息。例如，最小带宽信息和/或最大带宽信息可以是在感知测量过程或者感知测量结果报告过程中使用的带宽。例如，可以依据设备支持的带宽信息来设计感知测量过程所使用的感知测量帧，例如，NDP(空数据分组：null data packet)帧。
作为非限制性实施例，最小带宽信息可以指20MHz，最大带宽信息可以指320MHz。然而，本公开不限于此，可以根据设备的硬件能力或相关协议/标准规定在20MHz、40MHz、80MHz、160MHz、320MHz等带宽大小之中确定最小带宽信息和/或最大带宽信息。此外，在第一消息帧中，可以利用一个比特位来标识设备支持的最小带宽信息(例如，20MHz)，例如，当该比特位被设置为第一值(例如但不限于，1)时，可以标识设备支持利用20MHz的最小带宽进行感知测量。然而，这仅是示例性的，本公开不限于此，例如，可以利用两个或更多个比特位来标识设备支持的最小带宽信息。此外，在第一消息帧中，可以利用多个比特位(例如，三个比特位)来标识设备支持的最大带宽信息(例如，320MHz)，例如，当三个比特位被设置为第二值(例如但不限于，111)时，可以标识设备支持利用320MHz的最大带宽进行感知测量。然而，这仅是示例性的，本公开不限于此，例如，可以利用更少或更多个比特位来标识设备支持的最大带宽信息。
在本公开的一个实施例中，设备支持的空间流数量信息可以包括：设备 支持的用于感知测量的最小空间流数量(NSS)和/或最大空间流数量。例如，最小NSS和/或最大NSS可以是在感知测量过程或者感知测量结果报告过程中使用的NSS。例如，可以依据设备支持的NSS来设计感知测量过程所使用的感知测量帧，例如，NDP帧。
作为非限制性实施例，最小NSS可以为1，最大NSS可以为16或者8，然而本公开不限于此，其他大小的NSS也包括在本公开的范围内。在第一消息帧中，可以利用一个比特位来标识支持的最小NSS，例如，当该比特位被设置为第一值(例如但不限于，1)时，可以标识设备支持最小利用1个NSS进行感知测量。然而，这仅是示例性的，本公开不限于此，例如，可以利用两个或更多个比特位来标识设备支持的最小NSS。在第一消息帧中，可以利用多个比特位(例如，四个比特位)来标识支持的最大NSS，例如，当四个比特位被设置为第三值(例如但不限于，1111)时，可以标识设备最大支持利用16个NSS进行感知测量；例如，当四个比特位被设置为第四值(例如但不限于，0111)时，可以标识设备最大支持利用8个NSS进行感知测量。然而，这仅是示例性的，本公开不限于此，例如，可以利用更少或更多个比特位来标识设备支持的最大NSS。
在本公开的一个实施例中，设备支持的调制与编码策略(MCS，modulation and coding scheme)信息可以与设备支持的带宽信息相关联。可以在第一消息帧中设置MCS的索引值，以标识设备在感知测量中可以支持使用的传输资源。例如，以索引值标识的MCS可以包括与传输资源对应的各种参数，例如，空间流数量、调制方式、速率等。不同带宽下的MCS可以不同，因此，第一消息帧中包括的MCS可以与设备支持的带宽相关联。
在本公开的一个实施例中，设备支持的接收和发送的能力信息可以指设备在不同的资源单元(RU)分配下对4096-QAM(正交幅度调制：QAM，Quadrature Amplitude Modulation)、1024-QAM、256-QAM、64-QAM、16-QAM、QBSK和/或BPSK接收和发送能力的支持。例如，设备支持的接收和发送的能力信息可以指设备在最小带宽(例如，20MHz)的情况下对4096-QAM、1024-QAM、256-QAM、64-QAM、16-QAM、QBSK和/或BPSK接收和发送能力的支持。然而，本公开不限于此，设备支持的接收和发送的能力信息也可以指设备在其他带宽下的各种调制方式的接收和发送能力。作为非限制性的实施例，RU可以为26-tone、52-tone、106-tone、52+26- tone、106+26-tone等各种大小的单资源单元(SRU)或复合资源单元(MRU)。例如，在第一消息帧中，可以通过设备支持的接收和发送的能力信息来标识设备是否支持4096-QAM的发送、4096-QAM的接收、1024-QAM的发送、1024-QAM的接收、256-QAM的发送、256-QAM的接收、64-QAM的发送、64-QAM的接收、16-QAM的发送、16-QAM的接收、QBSK的发送、QBSK的接收、BPSK的发送、和/或BPSK的接收。例如，可以利用一个或更多个比特位来标识设备支持的接收和发送的能力信息。例如，在设备为发起方的情况下，可以在第一消息帧中标识发起方支持4096-QAM的发送、1024-QAM的发送、256-QAM的发送、64-QAM的发送、16-QAM的发送、QBSK的发送、和/或BPSK的发送；在设备为响应方的情况下，可以在第一消息帧中标识发起方支持4096-QAM的接收、1024-QAM的接收、256-QAM的接收、64-QAM的接收、16-QAM的接收、QBSK的接收、和/或BPSK的接收。
在步骤220中，发送第一消息帧。在图2的通信方法应用于发起方的情况下，发起方可以在步骤220中向响应方发送第一消息帧，并且上述步骤210中第一消息帧包括的感知操作参数能力信息可以指发起方的感知操作参数能力。在图2的通信方法应用于响应方的情况下，响应方可以在步骤220中向发起方发送第一消息帧，并且上述步骤210中第一消息帧包括的感知操作参数能力信息可以指响应方的感知操作参数能力。
在本公开的实施例中，根据感知会话建立发生的通信阶段，第一消息帧可以具有不同的形式。例如，第一消息帧可以是探测或关联阶段中的帧，例如信标帧、关联请求帧、关联响应帧、探测响应帧；或者第一消息帧可以是新定义的感知会话建立(sensing session setup)帧或感知会话通知(sensing session Notification)帧等，例如，考虑到安全性和隐私性，第一消息帧可以是在发起方和响应方完成密钥协商后(例如，通过四步握手方式)发送的新定义的帧。稍后将结合图4至图6进行更详细的描述。
图3是示出根据示例实施例的发起方与接收方之间的交互通信的流程图。在图3中，作为非限制的实施例，发起方可以是AP，响应方可以是STA。
参照图3，发起方AP可以向响应方STA发送第一消息帧，其中，第一消息帧可以包括发起方AP支持的感知操作参数能力信息。例如，第一消息帧可以包括：发起方AP支持的带宽信息、发起方AP支持的空间流数量信息、发起方AP支持的调制与编码策略信息、以及发起方AP支持 的接收和发送的能力信息中的至少一项。响应方STA可以解析接收到的第一消息帧，并且获知发起方AP的感知操作参数能力信息。上文已经参照图2的各个实施例对带宽信息、空间流数量信息、调制与编码策略信息以及接收和发送的能力信息分别进行了描述，为了简明，在此省略重复的描述。此外，仅作为描述性的实施例，发起方AP支持的上述感知操作参数能力信息可以以感知会话信息元素的形式携带在第一消息帧中。
继续参照图3，响应方STA可以向发起方AP发送第二消息帧，其中，第二消息帧可以包括响应方STA支持的感知操作参数能力信息。例如，第一消息帧可以包括：响应方STA支持的带宽信息、响应方STA支持的空间流数量信息、响应方STA支持的调制与编码策略信息、以及响应方STA支持的接收和发送的能力信息中的至少一项。发起方AP可以解析接收到的第一消息帧，并且获知响应方STA的感知操作参数能力信息。上文已经参照图2的各个实施例对带宽信息、空间流数量信息、调制与编码策略信息以及接收和发送的能力信息分别进行了描述，为了简明，在此省略重复的描述。此外，仅作为描述性的实施例，响应方STA支持的上述感知操作参数能力信息可以以感知会话信息元素的形式携带在第二消息帧中。
发起方AP与响应方STA在感知测量会话建立的过程中，应向对方标识其支持的感知操作参数能力信息，从而可以在后续的感知测量过程或者感知测量结果报告过程中利用他们能力信息来实现不同需求的感知测量。
在本公开的实施例中，根据感知会话建立发生的通信阶段，第一消息帧和第二消息帧可以具有不同的形式。
图4示出了在AP发送信标(beacon)帧以在AP与STA之间建立关联连接时进行感知测量会话建立的交互通信的流程图。
参照图4，在S410中，AP可以向STA广播信标帧，并且信标帧可以包括AP支持的感知操作参数能力信息。换言之，信标帧可以对应于图2和图3中的第一消息帧。例如，信标帧可以包括：AP支持的带宽信息、AP支持的空间流数量信息、AP支持的调制与编码策略信息、以及AP支持的接收和发送的能力信息中的至少一项。可以在信标帧中对AP支持的感知操作参数能力信息进行加密，以保证通信安全性。STA可以解析接收到的信标帧，并且获知AP的感知操作参数能力信息。上文已经参照图2 的各个实施例对带宽信息、空间流数量信息、调制与编码策略信息以及接收和发送的能力信息分别进行了描述，为了简明，在此省略重复的描述。
在S420中，STA可以向AP发送关联请求帧，并且关联请求帧可以包括STA支持的感知操作参数能力信息。换言之，关联请求帧可以对应于图3中的第二消息帧。例如，关联请求帧可以包括：STA支持的带宽信息、STA支持的空间流数量信息、STA支持的调制与编码策略信息、以及STA支持的接收和发送的能力信息中的至少一项。AP可以解析接收到的关联请求帧，并且获知STA的感知操作参数能力信息。上文已经参照图2的各个实施例对带宽信息、空间流数量信息、调制与编码策略信息和接收和发送的能力信息分别进行了描述，为了简明，在此省略重复的描述。
在S430中，AP可以向STA发送关联响应帧，从而在AP与STA之间建立关联连接。
在图4中，AP和STA可以在建立关联阶段完成用于感知测量的感知操作参数能力信息的交换，从而能够节省信令并且适用于WLAN感知测量。此外，虽然图4中仅示出了一个STA，但这仅是为了描述的简洁，而不是对本公开的限制，例如，AP可以向多个STA广播信标帧，从而在与多个STA建立关联阶段实现感知会话建立过程中设备支持的感知操作参数的能力信息的交换。
图5示出了在STA发送探测请求(probe request)帧以在AP与STA之间建立关联连接时进行感知测量会话建立的交互通信的流程图。
参照图5，在S510中，STA可以向AP发送探测请求帧；在S520中，AP可以向STA回复探测响应(probe response)帧，并且探测响应帧可以包括AP支持的感知操作参数能力信息。换言之，探测响应帧可以对应于图2和图3中的第一消息帧。例如，探测响应帧可以包括：AP支持的带宽信息、AP支持的空间流数量信息、AP支持的调制与编码策略信息、以及AP支持的接收和发送的能力信息中的至少一项。STA可以解析接收到的探测响应帧，并且获知AP的感知操作参数能力信息。上文已经参照图2的各个实施例对带宽信息、空间流数量信息、调制与编码策略信息以及接收和发送的能力信息分别进行了描述，为了简明，在此省略重复的描述。
在S530中，STA可以向AP发送关联请求帧，并且关联请求帧可以包括STA支持的感知操作参数能力信息。换言之，关联请求帧可以对应 于图3中的第二消息帧。例如，关联请求帧可以包括：STA支持的带宽信息、STA支持的空间流数量信息、STA支持的调制与编码策略信息、以及STA支持的接收和发送的能力信息中的至少一项。AP可以解析接收到的关联请求帧，并且获知STA的感知操作参数能力信息。上文已经参照图2的各个实施例对带宽信息、空间流数量信息、调制与编码策略信息以及接收和发送的能力信息分别进行了描述，为了简明，在此省略重复的描述。
在S540中，AP可以向STA发送关联响应帧，从而在AP与STA之间建立关联连接。
在图5中，AP和STA可以在建立关联阶段完成用于感知测量的感知操作参数能力信息的交换，从而能够节省信令并且适用于WLAN感知测量。此外，将理解，虽然在图5中示出了，AP在探测响应帧中携带AP支持的感知操作参数能力信息，并且STA在关联请求帧中携带STA支持的感知操作参数能力信息，然而，这仅是示例性的，在可以保证通信的安全性的情况下，也可以在其他帧中携带各自的能力信息。
图6示出了在AP和STA完成了四步握手之后进行感知测量会话建立的交互通信的流程图。
参照图6，AP和STA可以通过S610至S640实现四步握手操作，从而完成设备间的密钥协商。
在S650中，AP可以向STA发送新定义的感知会话建立帧或者感知会话通知帧，并且感知会话建立帧或者感知会话通知帧可以包括AP支持的感知操作参数能力信息。换言之，感知会话建立帧或者感知会话通知帧可以对应于图2和图3中的第一消息帧。例如，感知会话建立帧或者感知会话通知帧可以包括：AP支持的带宽信息、AP支持的空间流数量信息、AP支持的调制与编码策略信息、以及AP支持的接收和发送的能力信息中的至少一项。STA可以解析接收到的感知会话建立帧或者感知会话通知帧，并且获知AP的感知操作参数能力信息。上文已经参照图2的各个实施例对带宽信息、空间流数量信息、调制与编码策略信息以及接收和发送的能力信息分别进行了描述，为了简明，在此省略重复的描述。

上文已经参照图2的各个实施例对带宽信息、空间流数量信息、调制与编码策略信息以及接收和发送的能力信息分别进行了描述，为了简明，在此省略重复的描述。
在步骤720中，基于第一消息帧执行关于感知测量的操作。例如，在图2的通信方法由发起方执行并且图7的通信方法可以由响应方执行的情况下，在步骤720中，响应方可以确定并且发送第二消息帧(如图3所描述的)，以使得发起方获得响应方支持的感知操作参数能力信息。例如，在图2的通信方法由响应方执行并且图7的通信方法可以由发起方执行的情况下，在步骤720中，发起方可以发起感知测量建立，从而在发起方与响应方之间执行感知测量操作和/或感知测量结果报告操作。
