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)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是用于无线网络的无线交换机，也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，AP可以作为发起方，客户端可以作为响应方。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。
发起方发起的WLAN感知会话(即，WLAN感知的过程)可以包括：WLAN感知会话的建立、WLAN感知测量的建立、以及WLAN感知测量的终止等。
在WLAN感知会话的建立中，感知会话被建立，并且与感知会话相关联的操作参数被确定，并在设备(发起方和响应方)之间进行交换。在WLAN感知测量的建立中，可以建立一个感知测量过程，并且在感知测量过程中执行感知测量。在WLAN感知测量的终止中，设备停止执行测量并且终止感知会话。
在一个感知会话中，可以进行一次或更多次感知测量的建立(即，建立一个或更多个感知测量过程)，每个感知测量过程可以包含至少一个感知测量事件。在每个感知测量事件中，可以在发起方与响应方之间进行感知测量。在这里，发起方可以发起感知测量事件并且接收感知测量反馈，响应方可以向发起方反馈感知测量的结果。例如，感知测量反馈可以在每个感知测量事件之后进行，称为及时反馈，或者在所有或部分感知测量事件完成后反馈感知测量的结果，称为延时反馈。
对于延时反馈，来自感知响应方的多个感知测量建立的感知测量结果可以包含在用于延迟报告的单个测量报告帧中。根据本公开的实施例，单个测量报告帧所包含的多个感知测量结果中的每一者可以包含信道状态信息 (CSI，channel state information)信息。例如，发起方可以支持从响应方发送的单个测量报告帧中获得多个感知测量结果，和/或响应方可以支持缓存多个感知测量结果并在单个测量报告帧中将其发送给发起方。也就是说，多个感知测量结果可以聚合在一个测量报告帧中进行反馈，但是目前缺乏发起方如何激活响应方发送测量报告帧的机制。
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，以至少解决上述技术问题。
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是由WLAN感知测量的发起方执行的方法。
参照图2，在步骤210中，可以确定触发帧，其中，该触发帧可以包括需要反馈感知测量结果的多个感知测量事件的信息，其中，多个感知测量事件对应于至少一个感知测量过程。换言之，触发帧中的信息可以指示针对至少一个感知测量过程的多个感知测量事件进行反馈。此外，在下文中，为了便于描述，感知测量结果可以被简称为“测量结果”。
在本公开的实施例中，确定触发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触发帧：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触发帧，对此本公开实施例不作具体限制。此外，虽然在本公开的实施例中，以触发帧的方式来触发对测量结果的反馈，然而本公开不限于此，例如，可以以其他消息帧的方式来请求反馈测量结果，例如，步骤210中的触发帧可以被替换为，例如，测量报告请求帧。
在步骤220中，可以发送触发帧。例如，发起方可以将触发帧(或测量报告请求帧)发送到响应方，以指示响应方对触发帧中所标识的多个感知测量事件的测量结果(CSI)进行反馈。
本公开的一个实施例，步骤210中所确定的触发帧可以对应于延迟反馈操作，并且发送触发帧的设备(发起方)支持延迟反馈操作，并且该支持是在感知测量会话建立过程(例如，参照图1描述的实施例中的“WLAN感知会话的建立”)中确定的。例如，发送触发帧的设备(发起方)对于延迟反馈操作的支持能力可以在感知测量参数信息元素中进行标识，需在 感知测量会话建立过程中确定。
本公开的一个实施例，步骤210中所确定的触发帧中的信息可以包括：分别与至少一个感知测量过程对应的至少一个感知测量建立标识符、以及多个感知测量事件中的与每个感知测量建立标识符对应的至少一个感知测量事件的标识符。至少一个感知测量建立标识符可以对应于至少一个感知测量过程，每个感知测量过程可以包括至少一个(一个或更多个)感知测量事件。可以以不同的方式来标识与每个感知测量建立标识符对应的至少一个感知测量事件。
本公开的一个实施例，步骤210中所确定的触发帧中的信息可以包括：分别与至少一个感知测量过程对应的至少一个感知测量建立标识符、以及多个感知测量事件中的与每个感知测量建立标识符对应的至少一个感知测量事件的标识符。其中，与每个感知测量建立标识符对应的至少一个感知测量事件的标识符可以包括：分别与至少一个感知测量事件对应的至少一个感知测量事件报告标识符。
在本公开的实施例中，触发帧中的信息可以指示针对一个感知测量过程中的多个感知测量事件的进行反馈。在此情况下，在一个测量过程中可以包含多个感知测量事件，并且多个感知测量事件的测量结果可以为延时反馈，那么触发帧(测量报告请求帧)的格式可以为下面的表1所示。
表1
Measurement setup ID Instance ID1 report Instance ID2 report …
在表1中，Measurement setup ID可以指触发帧中的感知测量建立标识符，用于标识感知测量过程。Instance ID1 report和Instance ID2 report等可以分别指与感知测量建立标识符对应的第一感知测量事件和第二感知测量事件的标识符。也就是说，对应于感知测量建立标识符Measurement setup ID的感知测量过程可以包括第一感知测量事件、第二感知测量事件等，当触发帧中包含如表1所示的信息时，可以指需要针对该感知测量过程中的第一感知测量事件、第二感知测量事件等反馈测量结果(例如，指示反馈每个感知测量事件的CSI)。
在本公开的实施例中，触发帧中的信息可以指示针对多个感知测量过程中的多个感知测量事件的进行反馈。在此情况下，多个感知测量过程可以包含多个感知测量事件，每个感知测量过程可以包括至少一个感知测量事件， 触发帧(测量报告请求帧)的格式可以为下面的表2所示。
表2
Figure PCTCN2021135850-appb-000001
在表2中，Measurement setup ID1、Measurement setup ID2等可以指触发帧中的感知测量建立标识符，用于标识第一感知测量过程、第二感知测量过程等。与Measurement setup ID1对应的Instance ID11 report和Instance ID12report等可以指与感知测量建立标识符Measurement setup ID1(第一感知测量过程)对应的第一感知测量事件和第二感知测量事件的标识符；与Measurement setup ID2对应的Instance ID21 report等可以指与感知测量建立标识符Measurement setup ID2(第二感知测量过程)对应的感知测量事件的标识符。也就是说，对应于感知测量建立标识符Measurement setup ID1的第一感知测量过程可以包括两个或更多个感知测量事件，对应于感知测量建立标识符的Measurement setup ID2的感知测量过程可以包括一个或更多个感知测量事件等，当触发帧中包含如表2所示的信息时，可以指需要针对第一感知测量过程中的第一感知测量事件、第二感知测量事件等以及第二感知测量过程中的感知测量事件等反馈测量结果(例如，指示反馈每个感知测量事件的CSI)。
根据本公开的一个实施例，可以以不同于表1和表2的方式来标识与每个感知测量建立标识符对应的至少一个感知测量事件的标识符。
步骤210中所确定的触发帧中的信息可以包括：分别与至少一个感知测量过程对应的至少一个感知测量建立标识符、以及多个感知测量事件中的与每个感知测量建立标识符对应的至少一个感知测量事件的标识符。其中，与每个感知测量建立标识符对应的至少一个感知测量事件的标识符可以包括：感知测量事件起始报告标识符以及感知测量事件数量，其中，感知测量事件起始报告标识符用于指示需要反馈测量结果的起始感知测量事件，感知测量事件数量用于指示自起始感知测量事件起之后的感知测量事件的数量。
例如，当触发帧中的信息可以指示针对一个感知测量过程中的多个感知测量事件的进行反馈时，触发帧(测量报告请求帧)的格式可以为下面的表3所示。为了简明，在下文描述中，省略与表1和表2相同的标识符的描述。
表3
Measurement setup ID Instance ID starting report Number of instance
参照表3，Instance ID starting report可以指感知测量事件起始报告标识符，Number of instance可以指感知测量事件数量。例如，当触发帧包含如表3所示的信息时，可以指示响应方针对与感知测量建立标识符Measurement setup ID对应的连续的多个感知测量事件进行测量结果(例如，CSI)的反馈。例如，连续的多个感知测量事件的起始感知测量事件可以由Instance ID starting report来标识，number of instance标识接下来的测量事件的数量。例如，当Instance ID starting report标识对应于该感知测量过程中的第一感知测量事件，并且number of instance标识的数量为2时，可以指示对该感知测量过程中的第一感知测量事件至第三感知测量事件反馈测量结果。
例如，当触发帧中的信息可以指示针对多个感知测量过程中的多个感知测量事件的进行反馈时，触发帧(测量报告请求帧)的格式可以为下面的表4所示。
表4
Figure PCTCN2021135850-appb-000002
参照表4，示出了与两个(或更多个)感知测量过程对应的感知测量建立标识符Measurement setup ID1和Measurement setup ID2等，以及与每个感知测量建立标识符对应的感知测量事件起始报告标识符(Instance ID starting report)和感知测量事件数量(Number of instance)。Measurement setup ID1和Measurement setup ID2中的感知测量事件起始报告标识符(Instance ID starting report)和感知测量事件数量(Number of instance)可以不同，然而，本公开不限于此。
表4中的感知测量建立标识符Measurement setup ID1和Measurement setup ID2及其对应的感知测量事件起始报告标识符(Instance ID starting report)和感知测量事件数量(Number of instance)可以类似于表3，在此省略重复的描述以避免冗余。
此外，虽然在表3和表4中示出了，每个感知测量建立标识符仅包含一个感知测量事件起始报告标识符(Instance ID starting report)及其对应的感知测量事件数量(Number of instance)，然而，本公开不限于此。例如， 每个感知测量建立标识符可以包含更多个不同的感知测量事件起始报告标识符及其各自对应的感知测量事件数量。
将理解，表1至表4所示的触发帧的格式(触发帧所包括的信息)仅是示例性的，本公开不限于此。可以省略表1至表4中的部分内容，例如，在表4中，当Measurement setup ID1和Measurement setup ID2对应的感知测量事件起始报告标识符和感知测量事件数量相同时，可以以一个感知测量事件起始报告标识符及其感知测量事件数量来标识与Measurement setup ID1和Measurement setup ID2二者对应的感知测量事件；或者可以合并表1至表4中的部分内容，例如，在表3或者表4中，对于Measurement setup ID1可以利用表1所示的格式来标识至少一个感知测量事件，而对于Measurement setup ID2可以利用表3所示的格式来标识至少一个感知测量事件；或者表1至表4还可以包括其他更多内容。
根据本公开的一个实施例，图2所示的通信方法可以由接入点设备(AP)来执行，例如，确定以及发送触发帧的设备(发起方)可以为接入点设备(AP)。在此情况下，触发帧中的信息除了包括参照表1至表4描述的任意实施例中所示的信息外，还可以包括：参与至少一个感知测量过程的一个或更多个站点的标识符。也就是说，接入点设备可以将触发帧发送到多个站点，以指示多个站点反馈多个感知测量事件的测量结果(例如，CSI)。
可以以不同的方式来标识参与至少一个感知测量过程的一个或更多个站点。根据本公开的实施例，触发帧中包括的一个或更多个站点的标识符可以包括以下至少一项：
与接入点设备建立关联通信的站点的标识符(AID)；
与接入点设备未建立关联通信的站点的标识符(UID)；
站点的MAC(Media Access Control，介质访问控制)地址。
例如，在发送触发帧的设备(发起方)为接入点设备并且指示一个站点的情况下，上述表1至表4可以分别变形为下面的表5至表8。
表5
AID/UID/MAC Measurement setup ID Instance ID1 report Instance ID2 report …
表6

表7
AID/UID/MAC Measurement setup ID Instance ID starting report Number of instance
表8
Figure PCTCN2021135850-appb-000004
在表5至表8中，除了还包括标识站点的AID/UID/MAC之外，其他内容与表1至表4相同，在此省略重复的描述以避免冗余。
然而，表5至表8所示的触发帧仅是示例性的，本公开不限于此。
根据本公开的实一个施例，触发帧中的信息除了包括参照表5至表8描述的任意实施例中所示的信息外，还可以包括：反馈每个感知测量事件的感知测量结果分配的通信资源单元(RU，radio unit)。对于不同的感知测量事件的反馈，AP为反馈感知测量事件分配的RU的大小可以不同，也可以相同。通过在触发帧中设置反馈每个感知测量事件所需的RU，可以合理地分配通信资源，使得接收方可以利用设置的RU对相应的感知测量事件进行反馈，避免设备间的干扰。
例如，在发送触发帧的设备(发起方)为接入点设备并且指示一个或更多个站点同时反馈多个测量结果的情况下，触发帧可以具有下面的表9至表12所示的格式。

Figure PCTCN2021135850-appb-000010
在表9至表12中，示出了AP指示至少一个站点反馈测量结果的示例(例如，表9和表11对应于一个站点的情况，表10和表12对应于两个站点的情况)。此外，虽然在表9至表12中示出了每个站点对应一个感知测量建立标识符，但是本公开不限于此，每个站点可以对应更多个感知测量建立标识符。另外，在表10至表12中示出了，RU与感知测量建立标识符相对应(例如，RU for measurement setup ID、RU for measurement setup ID1、RU for measurement setup ID2等)，其可以表示针对与相应的感知测量建立标识符对应的感知测量事件分配的RU是相同的。然而，本公开不限于此，例如，针对各个感知测量事件分配的RU可以是不同的，例如，表10至表12中的RU可以被设置为与感知测量事件相对应(例如，可以与表9中所示的RU for Instance ID1、RU for Instance ID2等类似)。
根据本公开的一个实施例，，图2所示的通信方法可以由非接入点设备(non-AP，例如，图1中的客户端)执行，例如，确定以及发送触发帧的设备(发起方)可以为非接入点设备。在此情况下，由于非接入点设备的能力限制，非接入点设备仅能向一个响应方发送如表1至表4所示的触发帧，以及从其接收针对多个感知测量事件的反馈(CSI)。
根据本公开的实施例的图2所示的通信方法以及参照表1至表12描述的触发帧可以触发包括多个测量结果的测量报告帧的发送，节省资源开销。

根据本公开的一个实施例，所接收的触发帧中的信息可以包括：分别与至少一个感知测量过程对应的至少一个感知测量建立标识符、以及多个感知测量事件中的与每个感知测量建立标识符对应的至少一个感知测量事件的标识符。其中，与每个感知测量建立标识符对应的至少一个感知测量事件的标识符可以包括：分别与至少一个感知测量事件对应的至少一个感知测量事件报告标识符。

根据本公开的一个实施例，触发帧中的信息除了包括参照表5至表8描述的任意实施例中所示的信息外，还可以包括：反馈每个感知测量事件的感知测量结果分配的通信资源单元，例如，如表9至表12中的任意实施例所述。
根据本公开的实施例，触发帧对应于延迟反馈操作，并且接收触发帧的设备支持延迟反馈操作，并且该支持是在感知测量会话建立过程中确定的。
上文参照表1至表12描述的触发帧及其包括的信息的实施例可以应用于此，为了简明，在此省略重复的描述。
根据本公开的实施例的图3所示的通信方法以及参照表1至表12描述 的触发帧可以触发包括多个测量结果的测量报告帧的发送，节省资源开销。
