关联接入点设备的方法、装置及存储介质
本申请实施例要求于2020年3月24日提交的申请号为202010215260.6、发明名称为“关联接入点设备的方法、装置及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请实施例中。
技术领域
本申请实施例涉及通信技术领域，特别涉及一种关联接入点设备的方法、装置及存储介质。
背景技术
当前，802.11标准中正在针对802.11ax的下一代极高吞吐量(extremely high throughput，EHT)进行讨论，考虑引入更多的空间流。也即是，通过增加空间流来提升吞吐量。但是，为了支持更多的空间流，接入点设备需要安装更多的天线，然而，受限于接入点设备的产品规格和尺寸规模，在现有的接入点设备上安装更多的天线实现起来比较困难。
在相关技术中，提出了一种基于多天线面板的多输入多输出(multi input multi output，MIMO)技术，通过该技术可以将多个天线面板装配在一个接入点设备上，每个天线面板装配有多个天线，从而形成一个具有多天线面板的接入点设备。然而引入具有多天线面板的接入点设备之后，如何关联具有多天线面板的接入点设备，以充分利用多天线面板的能力，从而实现高效的数据传输，提高吞吐量是当前亟需解决的一个重要问题。
发明内容
本申请实施例提供了一种关联接入点设备的方法、装置及存储介质，能够关联具有多天线面板的接入点设备，并充分利用多天线面板的能力，以提高吞吐量。所述技术方案如下：
第一方面，提供了一种关联接入点设备的方法，第一接入点设备包括多个天线面板，所述多个天线面板中的每个天线面板上设置有多个天线，该方法包括：第一接入点设备通过该多个天线面板广播信标帧；第一接入点设备接收站点设备发送的关联请求帧，关联请求帧携带偏好面板信息，偏好面板信息用于指示一个或多个第一天线面板，第一天线面板是指期望第一接入点设备服务该站点设备时使用的天线面板，且偏好面板信息由该站点设备根据信标帧确定；第一接入点设备向该站点设备发送关联应答帧，以关联该站点设备与第一接入点设备，关联应答帧用于指示一个或多个第二天线面板，第二天线面板是指第一接入点设备服务站点设备时实际使用的天线面板，且该一个或多个第二天线面板由第一接入点设备根据偏好面板信息确定。
在本申请实施例中，第一接入点设备可以通过多个天线面板广播信标帧，可以周期性地广播，也可以定时广播。在第一接入点设备广播信标帧之后，附近的站点设备可以接收到该信标帧，之后，该站点设备可以向第一接入点设备发送关联请求帧，以请求关联第一接入点设备，并在关联过程中，向第一接入点设备提出天线面板建议，之后，第一接入点设备可以 通过关联应答帧回应该建议，并完成站点设备与第一接入点设备之间的关联。
由于应用场景中可能存在不支持多天线面板MIMO(multi panel MIMO，MP MIMO)的站点设备，为了能够兼容不支持MP MIMO的站点设备和支持MP MIMO的站点设备，在本申请实施例中，第一站点设备可以通过广播的信标帧来兼容这两种站点设备。
可选地，第一接入点设备通过多个天线面板广播信标帧，包括：第一接入点设备在第一时刻通过一个或多个第三天线面板广播第一信标帧，在第二时刻通过一个或多个第四天线面板广播第二信标帧，第一信标帧为不支持MP MIMO的信标帧，第二信标帧为支持MP MIMO的信标帧，第一时刻与第二时刻相同或不同，第三天线面板为该多个天线面板中的一个天线面板，该一个或多个第四天线面板为多个天线面板中除该一个或多个第三天线面板之外的天线面板；其中，第一信标帧携带第一基础服务集合的标识(basic service set identity，BSSID)，第一BSS是通过该一个或多个第三天线面板创建的，第二信标帧携带第二BSS的标识，第二BSS的标识与第一BSS的标识不同，第二BSS是通过该一个或多个第四天线面板创建的。
也即是，为了解决兼容性问题，本申请实施例设计了两种信标帧，第一信标帧可以为传统信标帧(legacy beacon)，用于兼容不支持MP MIMO的站点设备，第二信标帧为新定义的信标帧，用于兼容支持MP MIMO的站点设备，第二信标帧的帧格式与第一信标帧的帧格式可以不同。另外，广播这两种信标帧的天线面板不同，广播时间可以是同时广播或者时分方式广播。
在本申请实施例中，第一接入点设备通过该多个天线面板广播信标帧之后，站点设备可以根据接收到的信标帧确定偏好面板信息，并将偏好面板信息携带在关联请求帧中，将关联请求帧发送给第一接入点设备，以向第一接入点设备提出期望第一接入点设备服务该站点设备时使用的天线面板。由于站点设备可能接收到所有天线面板广播的信标帧，也可能仅接收到部分天线面板广播的信标帧，且各个天线面板广播的信标帧中携带的天线面板的相关信息可能不同。基于此，站点设备根据信标帧确定偏好面板信息的实现方式有多种，接下来介绍其中的两种实现方式。
第一种实现方式，第一接入点设备通过多个天线面板广播信标帧时，一个天线面板所广播的信标帧携带相应天线面板的相关信息，例如该天线面板的标识、当前是否服务其他站点设备等信息。站点设备在接收到该天线面板广播的信标帧之后，可以获知该天线面板的相关信息。而由于各个天线面板的发送角度、发送功率等可能存在不同，站点设备可能仅接收到部分天线面板广播的信标帧，即使站点设备接收到了所有天线面板广播的信标帧，站点设备也无法确定是否接收到了第一接入点设备的所有天线面板广播的信标帧，也无法确定是否所有天线面板均可为其服务。基于此，站点设备仅仅可以根据所接收到的各个信标帧中所携带的相应天线面板的信息，来确定偏好面板信息。
在本申请实施例中，站点设备可以根据所接收到的各个信标帧的信号能量、信号角度等，对相应的天线面板进行评估，从这些信标帧所对应的各个天线面板中选择出一个或多个第一天线面板，作为偏好面板。其中，第一天线面板是这些信标帧所对应的各个天线面板中的一个，第一天线面板是指期望第一接入点设备服务该站点设备时使用的天线面板。

可选地，关联请求帧还携带信号能量指示信息，信号能量指示信息用于指示站点设备通过一个或多个第一天线面板中每个第一天线面板接收到信标帧的信号能量。
第二种实现方式，第一接入点设备通过多个天线面板广播信标帧时，一个天线面板所广播的信标帧携带所有天线面板的相关信息，例如该多个天线面板中每个天线面板的标识、各个天线面板当前是否服务其他站点设备等信息。站点设备在接收到一个天线面板广播的信标帧之后，即可以获知所有天线面板的相关信息，也可以确定各个天线面板是否可为其服务。基于此，站点设备仅仅可以根据所接收到的信标帧中所携带的该多个天线面板的相关信息，来确定偏好面板信息。
可选地，偏好面板信息包括第一比特序列，第一比特序列包括多个第一比特位，该多个第一比特位与多个天线面板一一对应，每个第一比特位上的比特值用于指示对应的天线面板是否为第一天线面板。也即是，关联请求帧携带第一接入点设备上的多个天线面板的标识，并用不同的比特值指示各个天线面板是否为偏好面板。
可选地，在第二种实现方式中，关联请求帧还可以携带信号能量指示信息。信号能量指示信息可以包括该站点设备通过该多个天线面板中每个天线面板接收到的信标帧的信号能量，信号能量指示信息的携带方式可以参照第一种实现方式。
在本申请实施例中，第一接入点设备在接收到携带偏好面板信息的关联请求帧之后，可以对偏好面板信息所指示的一个或多个第一天线面板进行评估之后，确定该一个或多个第二天线面板。也即是，第一接入点设备向站点设备发送关联应答帧之前，还包括：第一接入点设备根据偏好面板信息确定服务面板信息，服务面板信息用于指示一个或多个第二天线面板；在该一个或多个第一天线面板与该一个或多个第二天线面板不同的情况下，关联应答帧携带服务面板信息。
可选地，服务面板信息包括该一个或多个第二天线面板的标识；或者，服务面板信息包括第二比特序列，第二比特序列包括多个第二比特位，该多个第二比特位与该多个天线面板一一对应，每个第二比特位上的比特值用于指示对应的天线面板是否为第二天线面板。
可选地，关联应答帧还携带天线数量指示信息，天线数量指示信息用于指示一个或多个第二天线面板中每个第二天线面板上的天线数量。也即是，第一接入点设备可以进一步地将每个第一天线面板上的天线数量携带在关联应答帧中，以告知站点设备，便于站点设备根据天线数量更准确地获知每个第一天线面板的详细信息，以对各个第一天线面板的传输能力进行评估，后续可以根据评估结果向第一接入点设备提出偏好建议，或者可以请求控制第一接入点设备上的天线面板开启或关闭等。
可选地，在服务面板信息包括第二比特序列的情况下，第一接入点设备还可以将自身包括的各个天线面板上的天线数量，携带在关联应答帧中。
在本申请实施例中，第一接入点设备向站点设备发送关联应答帧之后，第一接入点设备与该站点设备即关联完成。之后，第一接入点设备可以服务该站点设备，也即该站点设备可以通过第一接入点设备与其他设备进行数据传输。第一接入点设备可以向该站点设备转发数 据帧，或者，接收该站点设备发送的数据帧，并转发给其他设备。由于第一接入点设备包括多个天线面板，该多个天线面板传输数据帧的方式可以为多面板联合传输方式或者单面板传输方式，第一接入点设备可以将向站点设备传输数据帧的方式告知给站点设备，站点设备可以准确获知当前所接收的数据帧具体是第一接入点设备上哪些天线面板传输的，进而可以根据接收到的数据帧的信号功率对这些天线面板进行评估。
也即是，第一接入点设备向站点设备发送关联应答帧之后，还包括：第一接入点设备向站点设备发送数据帧，该数据帧携带传输方式指示信息，传输方式指示信息用于指示该数据帧的传输方式是多面板联合传输方式还是单面板传输方式，以及指示用于传输该数据帧的天线面板。
为了进一步地利用多天线面板的能力，本申请实施例还提供了一种声明设备上多面板开关状态的方法，以告知其他设备当前自身的面板开关状态，便于进行面板评估、信道测量等。其中，接入点设备可以声明自身包括的各个天线面板的开关状态，例如，第一接入点设备可以向站点设备声明，也可以广播声明，或者在第一接入点设备为接入点协作组中的主接入点设备时，主接入点设备还可以向从接入点设备声明，从接入点设备也可以向主接入点设备声明。如果站点设备也包括多个天线面板，站点设备也可以向第一接入点设备声明自身的包括的各个天线面板的开关状态。接下来以第一接入点设备向站点设备声明自身的包括的各个天线面板的开关状态为例，对本申请实施例提供的声明设备上多面板开关状态的方法进行介绍。
可选地，设备声明面板开关状态的声明信息类型可以有多种，声明信息类型可以为面板开关状态声明、多链路面板状态声明、基于持续时间的面板功率节省声明、基于模式的面板功率节省声明等类型。
需要说明的是，本申请实施例提供的声明设备上多面板开关状态的方法的实施前提是，收发双发具备动态增减多面板支持(dynamic addition-subtraction support,Dass)能力。其中，站点设备和第一接入点设备可以在关联阶段交互是否具备Dass能力，也即是，站点设备可以将是否具备Dass能力的指示信息携带在关联请求帧中，第一接入点设备可以将是否具备Dass能力的指示信息携带在关联应答帧中。主接入点设备和从接入点设备可以在加入协作组时交互是否具备Dass能力。

图3是本申请实施例提供的一种关联接入点设备的方法的流程图，该方法可以应用于第 一接入点设备，第一接入点设备包括多个天线面板，该多个天线面板中的每个天线面板上设置有多个天线。请参考图3，该方法包括如下步骤。
步骤301：第一接入点设备通过多个天线面板广播信标帧。
在本申请实施例中，图1所示的系统架构中包括一个或多个接入点设备，第一接入点设备为其中一个接入点设备。第一接入点设备可以通过多个天线面板广播信标帧，可以周期性地广播，也可以定时广播。
在第一接入点设备广播信标帧之后，附近的站点设备可以接收到该信标帧，之后，该站点设备可以向第一接入点设备发送关联请求帧，以请求关联第一接入点设备。
示例性地，假设第一接入点设备为无线接入点(access point，AP)设备，站点设备为手机，该无线AP可以向周围环境广播信标帧，以告知自身的存在，手机通过扫描接收到该信标帧，也即是发现该无线AP的存在，可以向该无线AP发送关联请求帧，以请求接入该无线网络。
由于应用场景中可能存在不支持MP MIMO的站点设备，为了能够兼容不支持MP MIMO的站点设备和支持MP MIMO的站点设备，在本申请实施例中，第一站点设备可以通过广播的信标帧来兼容这两种站点设备。
可选地，第一接入点设备可以在第一时刻通过一个或多个第三天线面板广播第一信标帧，在第二时刻通过一个或多个第四天线面板广播第二信标帧，第一信标帧为不支持MP MIMO的信标帧，第二信标帧为支持MP MIMO的信标帧，第一时刻与第二时刻相同或不同，第三天线面板为多个天线面板中的一个天线面板，该一个或多个第四天线面板为多个天线面板中除该一个或多个第三天线面板之外的天线面板。其中，第一信标帧携带第一BSS的标识，第一BSS是通过该一个或多个第三天线面板创建的，第二信标帧携带第二BSS的标识，第二BSS的标识为与第一BSS的标识不同，第二BSS是通过该一个或多个第四天线面板创建的。
在本申请实施例中，第一接入点设备可以通过发送不同的信标帧来兼容不同的站点设备，第一信标帧为不支持MP MIMO的信标帧，用于兼容不支持MP MIMO的站点设备，第二信标帧为支持MP MIMO的信标帧，用于兼容支持MP MIMO的站点设备。
需要说明的是，第一BSS和第二BSS为第一接入点设备通过不同的天线面板创建的两个虚拟小区，第一BSSID和第二BSSID为不同的两个媒体接入控制(media access control，MAC)地址，两个虚拟小区对外形成两个虚拟AP。由于第一接入点设备的多个天线面板的MAC地址可以相同或不同，如果该多个天线面板的MAC地址相同，第一BSSID可以为该MAC地址，也即是第一BSSID即为天线面板的MAC地址，第二BSSID为虚拟出的不同于该MAC地址的一个标识。如果该多个天线面板的MAC地址不同，第一BSSID可以为虚拟的一个MAC地址，第二BSSID为虚拟的另一个MAC地址，或者，可以选择一个第三天线面板的MAC地址作为第一BSSID，还可以选择一个第四天线面板的MAC地址作为第二BSSID。也即是，确定的BSSID可以是用真实的MAC地址，也可以用新生成的MAC地址。
另外，通常接入点设备本身装配有内置天线，接入点设备作为一个独立的设备本身就对应有一个MAC地址，在创建一个BSS时，可以通过接入点设备本身以及天线面板来创建，该BSS的标识如果为一个虚拟MAC地址，该虚拟MAC地址可以是根据接入点设备本身的MAC地址以及天线面板的MAC地址生成的。
其中，第一信标帧可以为传统信标帧，第二信标帧为新定义的信标帧，第二信标帧的帧 格式与第一信标帧的帧格式可以不同。
另外，如果第一时刻与第二时刻相同，站点设备可以通过解析接收到的信标帧，根据两种信标帧的帧格式不同，来确定接收到的信标帧为第一信标帧还是第二信标帧。其中，不支持MP MIMO的站点设备可以正确地解析第一信标帧，而无法解析第二信标帧，或者无法正确解析第二信标帧，即使这类站点设备按照错误解析的第二信标帧来请求关联第一接入点设备，第一接入点设备在接收到该关联请求帧之后，也会拒绝该关联请求。支持MP MIMO的站点设备可以正确地解析第二信标帧，也可以正确地解析第一信标帧，但是这类站点设备会根据帧格式区分出第一信标帧和第二信标帧，仅通过第二信标帧来请求关联第一接入点设备。
如果第一时刻与第二时刻不同，站点设备可以在第一次接收到信标帧之后，解析该信标帧，并记录接收时间，在成功通过该信标帧关联第一接入点设备，以及第二次接收到相同的信标帧之后，获知该信标帧的广播周期，之后，该站点设备可以根据广播周期来同步接收并解析该信标帧，而忽略与该广播周期不同步的其他信标帧。
图4是本申请实施例提供的一种接入点设备广播信标帧的示意图。参见图4，假设第一时刻与第二时刻不同，第一接入点设备可以在第一时刻通过天线面板1广播第一信标帧，在第二时刻通过天线面板2和天线面板3广播第二信标帧。
图5是本申请实施例提供的另一种接入点设备广播信标帧的示意图。参见图5，假设第一时刻与第二时刻相同，第一接入点设备可以在同一时刻通过天线面板1广播第一信标帧，并通过天线面板2和天线面板3广播第二信标帧。
步骤302：第一接入点设备接收站点设备发送的关联请求帧，该关联请求帧携带偏好面板信息，偏好面板信息用于指示一个或多个第一天线面板，第一天线面板是指期望第一接入点设备服务该站点设备时使用的天线面板。
在本申请实施例中，第一接入点设备通过多个天线面板广播信标帧之后，站点设备可以根据接收到的信标帧确定偏好面板信息，并将偏好面板信息携带在关联请求帧中，将关联请求帧发送给第一接入点设备，以向第一接入点设备提出期望第一接入点设备服务该站点设备时使用的天线面板。由于站点设备可能接收到所有天线面板广播的信标帧，也可能仅接收到部分天线面板广播的信标帧，且各个天线面板广播的信标帧中携带的天线面板的相关信息可能不同。基于此，站点设备根据信标帧确定偏好面板信息的实现方式有多种，接下来介绍其中的两种实现方式。
第一种实现方式，第一接入点设备通过多个天线面板广播信标帧时，一个天线面板所广播的信标帧携带相应天线面板的相关信息，例如该天线面板的标识、当前是否服务其他站点设备等信息。站点设备在接收到该天线面板广播的信标帧之后，可以获知该天线面板的相关信息。而由于各个天线面板的发送角度、发送功率等可能存在不同，站点设备可能仅接收到部分天线面板广播的信标帧，即使站点设备接收到了所有天线面板广播的信标帧，站点设备也无法确定是否接收到了第一接入点设备的所有天线面板广播的信标帧，也无法确定是否所有天线面板均可为其服务。基于此，站点设备仅仅可以根据所接收到的各个信标帧中所携带的相应天线面板的信息，来确定偏好面板信息。
在本申请实施例中，站点设备可以根据所接收到的各个信标帧的信号能量、信号角度等，对相应的天线面板进行评估，从这些信标帧所对应的各个天线面板中选择出一个或多个第一天线面板，作为偏好面板。其中，第一天线面板是这些信标帧所对应的各个天线面板中的一 个，第一天线面板是指期望第一接入点设备服务该站点设备时使用的天线面板。需要说明的是，具体的评估方法可以按照实际需求来设置，本申请实施例对此不作限定。
可选地，在本申请实施例中，偏好面板信息包括该一个或多个第一天线面板的标识，该一个或多个天线面板的标识在偏好面板信息中的顺序可以是任意一种顺序。
示例性地，由于在IEEE Std 802.11TM-2012的Table 8-22—Association Request frame body中定义了关联请求(association request)帧的帧体，其中定义了256个元素(element)，因此，在本申请实施例中，偏好面板信息的结构可以用元素的帧结构来设计。
图6是本申请实施例提供的一种偏好面板信息的结构示意图。参见图6，一个Octet(因特网标准使用八位组)为8比特，第一个Octet携带相应元素的标识(element ID，Ele ID)，第二个Octet携带相应元素的长度(length，L)，从第三个Octet开始携带偏好面板信息包括的一个或多个第一天线面板的标识，每个第一天线面板的标识所占的长度可以为一个Qctet，可以将一个第一天线面板称为一个偏好面板(perferred panel，Pref P)，偏好面板信息所包括的偏好面板的标识的个数等于评估之后选择出的偏好面板的个数。
可选地，在本申请实施例中，偏好面板信息包括第四比特序列，以及站点设备所接收到的各个信标帧对应的天线面板的标识，第四比特序列包括多个第四比特位，该多个第四比特位与站点设备所接收到的各个信标帧对应的天线面板一一对应，每个第四比特位上的比特值用于指示对应的天线面板是否为第一天线面板。
示例性地，偏好面板信息为一个元素，图7是本申请实施例提供的另一种偏好面板信息的结构示意图。参见图7，第三个Octet携带第四比特序列，第四比特序列可以称为多面板能力(Multi-panel capability，MP Capa)域，从第四个Octet开始携带站点设备所接收到的各个信标帧对应的天线面板的标识，每个天线面板的标识所占的长度可以为一个Qctet，偏好面板信息所包括的天线面板的标识的个数等于评估之后站点设备所接收到的信标帧的个数。
可选地，关联请求帧还可以携带信号能量指示信息，信号能量指示信息用于指示该站点设备通过一个或多个第一天线面板中每个第一天线面板接收到的信标帧的信号能量。
在本申请实施例中，信号能量指示信息包括该一个或多个第一天线面板中每个第一天线面板接收到的信标帧的信号能量，在偏好面板信息包括该一个或多个第一天线面板的标识的情况下，每个第一天线面板的标识之后可以紧跟相应的信号能量，或者，在最后一个天线面板的标识之后按照各个第一天线面板的顺序依次包括各个天线面板相应的信号能量。
示例性地，偏好面板信息和信号能量指示信息携带在一个元素中，图8是本申请实施例提供的另一种偏好面板信息的结构示意图。参见图8，从第三个Octet开始携带偏好面板信息包括的一个或多个第一天线面板的标识(P ID)，每个第一天线面板的标识之后可以紧跟相应的信号能量(receive signal strength indicator，RSSI)，也即是在图6的基础上，在每个偏好面板的标识之后紧跟相应的信号能量。
可选地，信号能量指示信息包括站点设备所接收到的各个信标帧对应的天线面板的信号能量，偏好面板信息包括第四比特序列的情况下，站点设备所接收到的各个信标帧对应的天线面板的标识之后可以紧跟相应的信号能量，或者，在最后一个天线面板的标识之后按照各个第四比特序列对应的天线面板的顺序依次包括相应的信号能量。
示例性地，如图9所示，可以在图7的基础上，在每个天线面板的标识之后紧跟相应的信号能量，得到偏好面板信息。
第二种实现方式，第一接入点设备通过多个天线面板广播信标帧时，一个天线面板所广播的信标帧携带所有天线面板的相关信息，例如该多个天线面板中每个天线面板的标识、各个天线面板当前是否服务其他站点设备等信息。站点设备在接收到一个天线面板广播的信标帧之后，即可以获知所有天线面板的相关信息，也可以确定各个天线面板是否可为其服务。基于此，站点设备仅仅可以根据所接收到的信标帧中所携带的该多个天线面板的相关信息，来确定偏好面板信息。
可选地，偏好面板信息包括第一比特序列，第一比特序列包括多个第一比特位，该多个第一比特位与该多个天线面板一一对应，每个第一比特位上的比特值用于指示对应的天线面板是否为第一天线面板。
示例性地，偏好面板信息为一个元素，图10是本申请实施例提供的又一种偏好面板信息的结构示意图。参见图10，第三个Octet携带第一比特序列，第一比特序列可以称为多面板能力域，第一比特序列所对应的各个天线面板的顺序可以与信标帧中各个天线面板的顺序相同。或者，信标帧中携带用于指示该多个天线面板的顺序的面板顺序信息，第一比特序列所对应的各个天线面板的顺序可以根据该面板顺序信息确定。
假设第一接入点设备包括三个天线面板，按顺序依次为天线面板1、天线面板2和天线面板3，站点设备所确定的第一天线面板为天线面板1和天线面板3，则第一比特序列可以为00000101，其中，后三个比特序列依次对应天线面板1、天线面板2和天线面板3，比特值为‘1’可以表示相应天线面板为第一天线面板，也即偏好面板，比特值为‘0’可以表示相应天线面板不是第一天线面板，也即不是偏好面板。
可选地，在第二种实现方式中，关联请求帧还可以携带信号能量指示信息。信号能量指示信息可以包括该站点设备通过该多个天线面板中每个天线面板接收到的信标帧的信号能量，信号能量指示信息的携带方式可以参照第一种实现方式。
示例性地，图11是本申请实施例提供的又一种偏好面板信息的结构示意图，参见图11，可以在图10的基础上，在第一比特序列，也即多面板能力域之后，按照第一比特序列中各个天线面板的顺序依次包括相应天线面板对应的信号能量。
步骤303：第一接入点设备向该站点设备发送关联应答帧，以关联该站点设备与第一接入点设备，该关联应答帧用于指示一个或多个第二天线面板，第二天线面板是指第一接入点设备服务该站点设备时实际使用的天线面板。
在本申请实施例中，第一接入点设备在接收到携带偏好面板信息的关联请求帧之后，可以根据该偏好面板信息，来确定一个或多个第二天线面板，第二天线面板是指第一接入点设备服务该站点设备时实际要使用的天线面板，并向站点设备发送关联应答帧，以向站点设备指示该一个或多个第二天线面板。也即是，站点设备向第一接入点设备提出偏好面板建议之后，第一接入点设备可以向站点设备回应该建议。
需要说明的是，第一接入点设备可以对偏好面板信息所指示的一个或多个第一天线面板进行评估之后，确定该一个或多个第二天线面板。
图12是本申请实施例提供一种的关联接入点设备的流程图。参见图12，站点(station，STA)设备可以在关联阶段向第一接入点(AP)设备发送关联请求帧，该关联请求帧携带偏好面板信息，第一接入点设备在接收到关联请求帧之后，可以向站点设备发送关联应答帧，且关联应答帧用于指示该一个或多个第二天线面板。
可选地，第一接入点设备在向该站点设备发送关联应答帧之前，可以根据偏好面板信息确定服务面板信息，服务面板信息用于指示一个或多个第二天线面板，在偏好面板信息所指示的一个或多个第一天线面板与该一个或多个第二天线面板不同的情况下，在关联应答帧中携带服务面板信息。可选地，在该一个或多个第一天线面板与该一个或多个第二天线面板相同的情况下，第一接入点设备可以不在关联应答帧中携带服务面板信息。
在本申请实施例中，第一接入点设备可以根据自身装配的各个天线面板的发射功率、发射角度，以及自身的天线面板之间的干扰关系、与其他设备的天线面板之间的干扰关系等，对偏好面板信息所指示的一个或多个第一天线面板进行评估，之后，从多个天线面板中选择出一个或多个第二天线面板，从而确定服务面板信息。需要说明的是，具体的评估方法也可以按照实际需求来设置，本申请实施例对此不作限定。
可选地，服务面板信息包括一个或多个第二天线面板的标识。或者，服务面板信息包括第二比特序列，第二比特序列包括多个第二比特位，该多个第二比特位与第一接入点设备包括的多个天线面板一一对应，每个第二比特位上的比特值用于指示对应的天线面板是否为第二天线面板。
示例性地，服务面板信息为一个元素，图13是本申请实施例提供的一种服务面板信息的结构示意图。参见图13，在服务面板信息包括一个或多个第二天线面板的标识的情况下，可以从第三个Octet开始携带服务面板信息包括的一个或多个第二天线面板的标识(panel ID)，每个第二天线面板的标识所占的长度可以为一个Qctet，可以将一个第二天线面板称为一个服务面板(serving panel，Serv P)，服务面板信息所包括的服务面板的标识的个数等于评估之后选择出的服务面板的个数。
示例性地，服务面板信息为一个元素，图14是本申请实施例提供的另一种服务面板信息的结构示意图。参见图14，在服务面板信息包括第二比特序列的情况下，第三个Octet携带第二比特序列，第二比特序列可以称为服务面板比特图(bitmap，Bitm)，第二比特序列所对应的各个天线面板的顺序可以与信标帧中各个天线面板的顺序相同。
可选地，关联应答帧还可以携带天线数量指示信息，天线数量指示信息用于指示该一个或多个第二天线面板中每个第二天线面板上的天线数量。也即是，第一接入点设备可以进一步地将每个第一天线面板上的天线数量携带在关联应答帧中，以告知站点设备，便于站点设备根据天线数量更准确地获知每个第一天线面板的详细信息，以对各个第一天线面板的传输能力进行评估，后续可以根据评估结果向第一接入点设备提出偏好建议，或者可以请求控制第一接入点设备上的天线面板开启或关闭等。
示例性地，天线数量指示信息为一个元素，图15是本申请实施例提供的一种天线数量指示信息的结构示意图。参见图15，第三个Octet携带第二天线面板的总个数(number，Num)，从第四个Octet开始，按照服务面板信息所包括各个第二天线面板的顺序，依次携带各个天线面板上的天线数量(antenna number，Ant Num)。
或者，也可以在图13的基础上，将各个第二天线面板上的天线数量紧跟在相应第二天线面板的标识之后。又或者，也可以在图13的基础上，将各个第二天线面板上的天线数量，按照服务面板信息所包括各个第二天线面板的顺序，携带在最后一个第二天线面板的标识之后。
可选地，在服务面板信息包括第二比特序列的情况下，第一接入点设备还可以将自身包括的各个天线面板上的天线数量，携带在关联应答帧中。
示例性地，可以在图14的基础上，按照第二比特序列包括的各个天线面板的顺序，将各个天线面板上的天线数量依次携带在第二比特序列之后。
在本申请实施例中，第一接入点设备向站点设备发送关联应答帧之后，第一接入点设备与该站点设备即关联完成。之后，第一接入点设备可以服务该站点设备，也即该站点设备可以通过第一接入点设备与其他设备进行数据传输。第一接入点设备可以向该站点设备转发数据帧，或者，接收该站点设备发送的数据帧，并转发给其他设备。
在本申请实施例中，由于第一接入点设备包括多个天线面板，该多个天线面板传输数据帧的方式可以为多面板联合传输方式或者单面板传输方式，第一接入点设备可以将向站点设备传输数据帧的方式告知给站点设备，站点设备可以准确获知当前所接收的数据帧具体是第一接入点设备上哪些天线面板传输的，进而可以根据接收到的数据帧的信号功率对这些天线面板进行评估，后续也可以根据评估结果向第一接入点设备提出偏好建议，或者也可以请求控制第一接入点设备上的天线面板开启或关闭等。需要说明的是，具体的评估方法也可以按照实际需求来设置，本申请实施例对此不作限定。
在一些实施例中，第一接入点设备可以向站点设备发送数据帧，该数据帧携带传输方式指示信息，传输方式指示信息用于指示该数据帧的传输方式是多面板联合传输方式还是单面板传输方式，以及指示用于传输该数据帧的天线面板。
可选地，传输方式指示信息包括第五比特序列，第五比特序列的长度可以根据第一接入点设备中最多可以装配的天线面板的个数确定。如果第一接入点设备中最多可以装配3个天线面板，那么第五比特序列的长度可以为2，如果第一接入点设备中最多可以装配6个天线面板，那么第五比特序列的长度可以为3。
假设第一接入点设备中最多可以装配3个天线面板，分别为天线面板1、天线面板2和天线面板3，第五比特序列的长度为2，如果第五比特序列的值为0，可以表示相应数据帧的传输方式为多面板联合传输方式，如果第五比特序列的值不为0，可以表示相应数据帧的传输方式为单面板传输方式。其中，如果第五比特序列的值为0，可以表示使用天线面板1、天线面板2和天线面板3进行多面板联合传输，如果第五比特序列的值为1、2或者3，可以分别表示使用天线面板1、天线面板2或天线面板3进行单面板传输。在另一些实施例中，如果第五比特序列的值不为0，也可以表示相应数据帧的传输方式为多面板联合传输方式，例如，定义第五比特序列的值为1时，表示相应数据帧的传输方式为天线面板1和天线面板2联合传输，定义第五比特序列的值为2时，表示相应数据帧的传输方式为天线面板1和天线面板3联合传输，定义第五比特序列的值为3时，表示相应数据帧的传输方式为天线面板2和天线面板3联合传输。也即是，天线面板1、天线面板2和天线面板3的3种不同组合，可以形成3种面板组合模式，如果第五比特序列的值为1、2或者3，可以分别表示使用相应面板组合模式进行多面板联合传输。
示例性地，假设第五比特序列的长度可以为2，也即包括两比特的数据，第一接入点设备可以在物理协议数据单元(physical protocol data unit,PPDU)帧中携带传输方式指示信息，也即携带两比特的第五比特序列，图16、17和18是本申请实施例提供的三种携带传输方式指示信息的数据帧的结构示意图。参见图16，可以在PPDU帧中的EHT-SIG-A中用两比特表示传输方式指示信息。参见图17，在图16的基础上，具体地可以在EHT-SIG-A中的BSS color(BSS Col，小区颜色)域中的LSB中用两比特携带传输方式指示信息。参见图18，可 以在PPDU帧中的通用信息域中的版本相关域(version dependent fields，Ver D F)中用两比特携带传输方式指示信息。可选地，也可以在MPDU(MAC PDU)帧中，也即是在PPDU帧中的Data字段中，用两比特携带传输方式指示信息，例如，可以在MPDU帧体的最开始的位置之前增加两比特位用于携带传输方式指示信息，又如，可以在帧控制域中用两比特(如第三和第四比特位)携带传输方式指示信息。
另外，需要说明的是，上述实施例中所涉及的站点设备通过第一接入点设备传输数据帧的实现方式中，是以站点设备均为支持MP MIMO的设备为前提进行介绍的，也即是不存在兼容性问题，在这种情况下，如果第一接入点设备上的多个天线面板的MAC地址不同，则第一接入点设备可以通过该多个天线面板虚拟出一个BSS，该BSS的标识(BSSID)为一个虚拟MAC地址，该多个天线面板共同使用该BSSID，用于对外体现为一个接入点设备，也即是，在站点设备接收到数据帧之后，通过BSSID获知当前通信对端为一个接入点设备。而每个天线面板有唯一的标识，也即各个天线面板的标识(panel ID，P ID)不同，数据帧携带的传输方式指示信息所指示的天线面板，用于指示站点设备获知所关联的接入点设备实际传输相应数据帧所使用的天线面板。另外，如果考虑上述兼容性的问题，上述实施例中所涉及的站点设备通过第一接入点设备传输数据帧的实现方式中，站点设备为支持MP MIMO的设备，第一接入点设备可以通过一个或多个第四天线面板虚拟出一个BSS，也即创建第二BSS，用于服务支持MP MIMO的站点设备。
为了进一步地利用多天线面板的能力，本申请实施例还提供了一种声明设备上多面板开关状态的方法，以告知其他设备当前自身的面板开关状态，便于进行面板评估、信道测量等。其中，接入点设备可以声明自身包括的各个天线面板的开关状态，例如，第一接入点设备可以向站点设备声明，也可以广播声明，或者在第一接入点设备为接入点协作组中的主接入点设备时，主接入点设备还可以向从接入点设备声明，从接入点设备也可以向主接入点设备声明。如果站点设备也包括多个天线面板，站点设备也可以向第一接入点设备声明自身的包括的各个天线面板的开关状态。
接下来以第一接入点设备向站点设备声明自身的包括的各个天线面板的开关状态为例，对本申请实施例提供的声明设备上多面板开关状态的方法进行介绍。

示例性地，图19是本申请实施例提供的一种接入点设备声明多面板开关状态的流程图。参见图19，站点设备(STA)可以向第一接入点设备发送面板状态获取请求帧，第一接入点设备(AP)可以向站点设备发送面板状态应答帧，以将自身包括的每个天线面板的开关状态告知该站点设备。
可选地，设备声明面板开关状态的声明信息类型可以有多种，声明信息类型可以为面板开关状态声明、多链路面板状态声明、基于持续时间的面板功率节省声明、基于模式的面板功率节省声明等类型。
需要说明的是，本申请实施例提供的声明设备上多面板开关状态的方法的实施前提是， 收发双发具备动态增减多面板支持(Dass)能力。其中，站点设备和第一接入点设备可以在关联阶段交互是否具备Dass能力，也即是，站点设备可以将是否具备Dass能力的指示信息携带在关联请求帧中，第一接入点设备可以将是否具备Dass能力的指示信息携带在关联应答帧中。主接入点设备和从接入点设备可以在加入协作组时交互是否具备Dass能力。
示例性地，参见图20，是否具备Dass能力的指示信息为一个元素，可以定义EHT能力元素，并在其中使用一个比特位表示本设备是否具备Dass能力，例如，该比特位1可以表示具有，为0表示不具有。
可选地，第一接入点设备向该站点设备发送关联应答帧之后，还可以主动向站点设备发送第一面板状态声明帧，第一面板状态声明帧携带第一面板状态信息，第一面板状态信息用于指示多个天线面板中每个天线面板的开关状态。
可选地，第一接入点设备向站点设备发送第一面板状态声明帧之后，还可以接收站点设备发送的声明确认帧，声明确认帧用于指示站点设备确认接收到第一面板状态声明帧。
示例性地，第一面板状态信息可以为一个元素。或者，在IEEE Std 802.11 TM-2012标准定义的元素全部已被使用的情况下，如图21所示，也可以在其中一个元素中定义子元素(subelement，Subele)，其中，长度表示该元素的总长度，包括子元素的长度，子元素的长度为可变长度，子元素部分可以根据子元素的标识不同来进行扩展，也即是在一个元素中扩展一个或多个子元素，每个子元素的标识不同，在元素不充足的情况下，可以定义一个子元素来表示第一面板状态信息。
由前述可知，设备声明面板开关状态的声明信息类型可以有多种，参见表1，表1中示出了定义的几种子元素以及每种子元素对应的声明信息类型，表1还示出了定义一个信息类型为声明的回复确认信息的子元素，用来表示声明确认帧，声明确认帧包括声明的回复确认信息。
