本公开实施例提供了一种通信方法、电子设备及存储介质，用以提供一种支持A-PPDU传输的机制。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
如图1中所示，本公开实施例提供了一种通信方法，可选地，所述方法可应用于接入点(Access Point，AP)设备；该方法可以包括以下步骤：
步骤101，确定第一无线帧，其中，所述第一无线帧包括第一标识信息，所述第一标识信息指示接入点设备所支持的发送聚合物理层协议数据单元A-PPDU的每个物理层协议数据单元PPDU的带宽信息；所述PPDU为所述接入点设备为站点设备分配的。
在无线局域网中，一个基本服务集(Basic Service Set，BSS)可以由AP以及与AP通信的一个或多个站点(Station，STA)构成。一个基本服务集可以通过其AP连接到分配系统(Distribution System，DS)，然后再接入到另一个基本服务集，构成扩展的服务集(Extended Service Set，ESS)。
可选地，AP例如具有无线至有线桥接(Bridging)功能的设备，AP负责将有线网络所提供的服务延伸至无线网络；STA例如具有无线网络接入功能的电子设备，提供帧传递(Frame Delivery)服务让信息得以传递。
在本公开实施例中，AP和STA可以为支持多连接的设备，例如，可以被分别表示为AP MLD和non-AP MLD。为了便于描述，在下文中，主要描述一个AP与一个STA在多连接下进行通信的示例，然而，本公开的示例实施例不限于此。
作为第一示例，参见图2以及图3，AP MLD可以表示支持多连接通信功能的接入点，non-AP MLD可以表示支持多连接通信功能的站点。
参照图2，AP MLD可以包括三个附属AP，如图2所示的AP1、AP2和AP3；每个AP可以分别工作在连接1、连接2以及连接3；non-AP MLD也可以工包括三个附属STA，如图2所示的STA1、STA2和STA3；STA1工作在连接1、STA2工作在连接2以及STA3工作在连接3。在图3的示例中，假设AP1与STA1通过对应的第一连接Link 1进行通信，类似地，AP2与STA2通过对应的第二连接Link 2进行通信，AP通过第三连接Link  3与STA3进行通信。此外，Link 1至Link 3可以分别是不同频率下的多个连接，例如，2.4GHz、5GHz、6GHz下的连接，或2.4GHz下的几个相同或不同带宽的连接。此外，在每个连接下可以存在多个信道。可以理解的是，图2所示的通信场景仅是示例性的，本公开构思不限于此，例如，AP MLD可以连接到多个(三个)non-AP MLD，或者在每个连接下，AP可以与多个其他类型的站点进行通信。
通常情况下，AP MLD和与其建立关联连接的non-AP MLD中的一些non-AP MLD能够支持的最大工作带宽不同。例如，AP MLD可能支持最大工作带宽320MHz或640MHz，而与AP MLD建立关联的一些non-AP MLD可能只支持最大工作带宽160MHz或80MHz，或者更小。也就是说，在AP MLD和non-AP MLD传输的PPDU具有不对称的工作带宽。在此情况下，为了更大化的利用AP MLD的能力，提高系统的吞吐量，可以传输A-PPDU。
本公开实施例中，第一无线帧例如包括信标(Beacon)帧和/或探测响应(Probe Response)帧，AP通过第一无线帧与STA建立初始关联(Association)，以实现将无线帧传输给STA。
AP在第一无线帧中携带第一标识信息，所述第一标识信息指示接入点设备所支持的发送聚合物理层协议数据单元A-PPDU的每个物理层协议数据单元PPDU的带宽信息；其中，A-PPDU包括多个PPDU，每个PPDU可能具有不同的带宽，相当于A-PPDU作为一个PPDU组合，而第一标识信息指示该PPDU组合里每个PPDU的带宽；作为第二示例，如图4所示，A-PPDU包括3个PPDU，带宽分别为：PPDU-1带宽为160MHz，其接收端可以为STA1；PPDU-2带宽为80MHz，其接收端可以为STA2，PPDU-3带宽为80MHz，其接收端可以为STA；第一标识信息可分别标识3个PPDU的带宽信息，同时也标识不同的PPDU的接收端为不同的STA。
其中，A-PPDU的每个PPDU的带宽可根据AP所支持的最大带宽确定；例如，在6GHz频谱下，AP支持最大320MHz带宽时，AP支持上下行接收A-PPDU中PPDU带宽的组合可以包括：(1) 80MHz+80MHz+160MHz；(2)80MHz+80MHz+80MHz+80MHz；(3)160+160MHz。又或者，在6GHz频谱下，当AP支持最大640MHz时，AP支持上下行接收A-PPDU中PPDU带宽的组合可以包括：(1)8*80MHz(2)4*160MHz(3)2*320MHz(4)320+2*160(5)3*160MHz+2*80MHz(6)2*160MHz+4*80MHz(7)160MHz+3*160组合；其中，“*”表示乘号。如上述某些组合也可能存在5GHz频谱下。
其中，所述PPDU为所述接入点设备为站点设备分配的，例如，为每个STA分配PPDU，而所分配的PPDU的带宽大于或等于对应的STA的最大工作带宽。
步骤102，发送所述第一无线帧。
例如，可以通过图3中多个连接中的任一连接向STA发送第一无线帧，使得STA可以获得关于A-PPDU的每个PPDU的带宽信息，例如根据每个PPDU的带宽信息确定AP为其分配的目标PPDU，接收所述目标PPDU，进而实现A-PPDU的传输。
本公开实施例中，确定并发送第一无线帧，其中，所述第一无线帧包括第一标识信息，所述第一标识信息指示接入点设备所支持的发送聚合物理层协议数据单元A-PPDU的每个物理层协议数据单元PPDU的带宽信息；所述PPDU为所述接入点设备为站点设备分配的。本公开实施例提供了一种支持A-PPDU传输的机制。
本公开实施例提供了一种通信方法，可选地，所述方法可应用于接入点设备；该方法可以包括以下步骤：
确定第一无线帧，其中，所述第一无线帧包括第一标识信息，所述第一标识信息指示接入点设备所支持的发送聚合物理层协议数据单元A-PPDU的每个物理层协议数据单元PPDU的带宽信息；所述PPDU为所述接入点设备为站点设备分配的；所述第一无线帧中还包括带宽标识信息，所述带宽标识信息指示所述接入点设备的最大工作带宽；
发送所述第一无线帧。
其中，所述第一无线帧中还包括带宽标识信息，所述带宽标识信息指示所述接入点设备的最大工作带宽，例如在不同频段下的最大工作带宽，以便STA获知AP的带宽能力信息。
可选地，所述带宽标识信息携带在所述第一无线帧的超高可靠性操作URH operation能力信息元素中。
本公开实施例中，所述方法还包括以下步骤：
接收所述站点设备发送的第二无线帧；其中，所述第二无线帧包括第二标识信息，所述第二标识信息指示所述站点设备所支持的最大工作带宽或可用工作带宽；
根据所述第二标识信息为所述站点设备分配所述PPDU；其中，为所述站点设备分配所述PPDU的覆盖带宽大于或等于所述站点设备所支持的最大工作带宽。
可选地，所述第二无线帧例如包括关联请求(Association Request)帧和/或探测请求(Probe Request)帧。例如，STA发送第二无线帧与接入点设备进行初始关联，且通过第二标识信息指示在所述站点设备所支持的最大工作带宽或可用工作带宽，即通过第二标识信息指示STA的带宽能力信息；带宽能力信息包括最大工作带宽或可用工作带宽；例如，STA支持最大工作带宽为160MHz，则其支持A-PPDU中为其配置PPDU为带宽为160MHz，或2个80MHz，则可用工作带宽包括160MHz以及80MHz。
AP根据其自身的最大工作带宽以及每个STA的最大工作带宽，为每个STA分配PPDU(或分配PPDU的带宽)，确保为一个STA分配的所有PPDU的覆盖带宽(覆盖带宽即为该STA分配的所有PPDU带宽之和)之和大于或等于所述站点设备所支持的最大工作带宽，以使得为该STA分配的PPDU带宽能覆盖该STA的最大工作带宽。
本公开实施例中，确定并发送第一无线帧，其中，所述第一无线帧包括第一标识信息，所述第一标识信息指示接入点设备所支持的发送聚合物 理层协议数据单元A-PPDU的每个物理层协议数据单元PPDU的带宽信息；所述PPDU为所述接入点设备为站点设备分配的。本公开实施例提供了一种支持A-PPDU传输的机制。
参见图5，本公开实施例提供了一种通信方法，可选地，所述方法可应用于STA，STA例如具有无线网络接入功能的电子设备，例如向用户提供语音和/或数据连通性的设备、具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。
该方法可以包括以下步骤：
步骤501，接收第一无线帧，其中，所述第一无线帧包括第一标识信息，所述第一标识信息指示接入点设备所支持的发送聚合物理层协议数据单元A-PPDU的每个物理层协议数据单元PPDU的带宽信息；所述PPDU为所述接入点设备为每个站点设备分配的。
其中，本公开实施例提供的通信方法的所应用WLAN的架构参考前述第一示例，在此不再赘述。
通常情况下，AP MLD和与其建立关联连接的non-AP MLD中的一些non-AP MLD能够支持的最大工作带宽不同。例如，AP MLD可能支持最大工作带宽320MHz或640MHz，而与AP MLD建立关联的一些non-AP MLD可能只支持最大工作带宽160MHz或80MHz，或者更小。也就是说，在AP MLD和non-AP MLD传输的PPDU具有不对称的工作带宽。在此情况下，为了更大化的利用AP MLD的能力，提高系统的吞吐量，可以传输A-PPDU。
本公开实施例中，第一无线帧例如包括信标(Beacon)帧和/或探测响应(Probe Response)帧，AP通过第一无线帧与STA建立初始关联(Association)，以实现将无线帧传输给STA。
STA获取第一无线帧中携带的第一标识信息，根据所述第一标识信息确定接入点设备所支持的发送聚合物理层协议数据单元A-PPDU的每个物理层协议数据单元PPDU的带宽信息；其中，A-PPDU包括多个PPDU，每个PPDU可能具有不同的带宽，相当于A-PPDU作为一个PPDU组合， 而第一标识信息指示该PPDU组合里每个PPDU的带宽；参见第二示例，如图4所示，A-PPDU包括3个PPDU，带宽分别为：PPDU-1带宽为160MHz，PPDU-2带宽为80MHz，PPDU-3带宽为80MHz，则第一标识信息可分别标识3个PPDU的带宽信息。
其中，A-PPDU的每个PPDU的带宽可根据AP所支持的最大带宽确定；例如，在AP支持最大320MHz带宽时，AP支持上下行接收A-PPDU中PPDU带宽的组合可以包括：(1)80MHz+80MHz+160MHz；(2)80MHz+80MHz+80MHz+80MHz；(3)160+160MHz。又或者，当AP支持最大640MHz时，AP支持上下行接收A-PPDU中PPDU带宽的组合可以包括：(1)8*80MHz(2)4*160MHz(3)2*320MHz(4)320+2*160(5)3*160MHz+2*80MHz(6)2*160MHz+4*80MHz(7)160MHz+3*160组合；其中，“*”表示乘号。
其中，所述PPDU为所述接入点设备为站点设备分配的，例如，为每个STA分配PPDU，而所分配的PPDU的带宽大于或等于对应的STA的最大工作带宽。
例如，STA可以通过图3中多个连接中的任一连接接收AP发送的第一无线帧，获得关于A-PPDU的每个PPDU的带宽信息，例如根据每个PPDU的带宽信息确定AP为其分配的目标PPDU，接收所述目标PPDU，进而实现A-PPDU的传输
