Description

通信方法及电子设备、存储介质 技术领域
本公开实施例涉及移动通信技术领域，具体而言，本公开实施例涉及一种通信方法及电子设备、存储介质。
背景技术
随着移动通信技术的迅速发展，无线保真(Wireless Fidelity，Wi-Fi)技术在传输速率以及吞吐量等方面已经取得了巨大的进步。目前，Wi-Fi技术所研究的内容例如320Mhz的带宽传输、多个频段的聚合及协同等，其主要的应用场景例如视频传输、增强现实(Augmented Reality，AR)、虚拟现实(Virtual Reality，VR)等。
具体地，多个频段的聚合及协同是指设备之间同时在2.4GHz、5.8GHz、6GHz及其他频段下进行通信，对于设备之间同时在多个频段下通信的场景，还需要定义新的介质访问控制(Media Access Control，MAC)机制来进行管理。此外，多频段的聚合及协同有望能够支持低时延传输。
目前，多频段的聚合及协同技术中，将支持的最大带宽为320MHz(160MHz+160MHz)，此外，还可能会支持240MHz(160MHz+80MHz)及现有标准支持的其它带宽。
在目前所研究的Wi-Fi技术中，多连接接入点设备(Access Point Multi-Link Device，AP MLD)可能删除其附属AP；因此，需要提供一种删除附属AP的实现方式，以完善附属AP的管控机制。

本公开实施例提供了一种通信方法及电子设备、存储介质，用以提供一种删除附属AP的实现方式。
其中，方法和电子设备、装置是基于同一申请构思的，由于方法和电子设备、装置解决问题的原理相似，因此方法和电子设备、装置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，所述方法可应用于电子设备，所述电子设设备可以是多连接接入点设备AP MLD，该方法可以包括以下步骤：
步骤101，确定第一无线帧；其中，所述第一无线帧中包括至少一个第一标识位，所述第一标识位指示对应的目标通信连接所属的附属AP将被删除。
通常情况下，多连接接入点设备(Access Point Multi-Link Device，AP MLD)可以随时删除其附属AP；例如，AP MLD确定删除附属AP-1之后，确定第一无线帧，所述第一无线帧可以是基本服务集切换管理请求(Basic Service Set Transition ManagementRequest，BTM Request)帧，例如AP MLD主动发送所述BTM Request帧，或响应于BSS转换管理查询帧而发送；AP MLD在第一无线帧中携带第一标识位，通过第一标识位指示目标通信连接所述的附属AP将会被删除(to-be-removed)。
具体地，目标通信连接为待删除的附属AP的通信连接，这样，通过第一标识位指示附属AP将被删除，以指示该附属AP将被删除；例如，第一标识位可以是连接位图Link Bitmap域中的指示位，将Link Bitmap域设置为2个字节，则可包括16个Link Bitmap指示位(即第一标识位)，标识附属AP支持16个link；其中，Link Bitmap指示位为“1”标识其对应的通信连接(即目标通信连接)将会被删除。
步骤102，在所述附属AP的至少一个通信连接下，发送所述第一无线帧。
其中，所述第一无线帧中包括一个或至少两个第一标识位，每个第一标识位可以分别标识一个通信连接；这样，AP MLD可以在一个通信连接下发送所述第一无线帧，通过发送一个第一无线帧指示多个通信连接将被删除，以节省信令消息，减少对网络资源的占用；AP MLD还可以在至少两个通信连接下发送所述第一无线帧。
本公开实施例中，AP MLD确定第一无线帧，并在所述附属AP的至 少一个通信连接下，发送所述第一无线帧；其中，所述第一无线帧中包括至少一个第一标识位，所述第一标识位指示对应的目标通信连接所属的附属AP将被删除；本公开实施例提供了一种删除附属AP的具体方式，以完善附属AP的管控机制。
如图2所示，本公开实施例提供了一种通信方法，可选地，所述方法可应用于电子设备，所述电子设设备可以是多连接接入点设备AP MLD，该方法包括：
步骤201，在第一无线帧中设置第一标识域，将第一标识位携带在所述第一标识域中；其中，所述第一无线帧中包括至少一个第一标识位，所述第一标识位指示对应的目标通信连接所属的附属AP将被删除；
步骤202，在所述附属AP的至少一个通信连接下，发送所述第一无线帧。
其中，所述第一无线帧可以是BTM Request帧，例如AP MLD主动发送所述BTM Request帧，或响应于BSS转换管理查询帧而发送；AP MLD在BTM Request帧中新增第一标识域，在第一标识域中携带第一标识位；例如，第一标识域为Link Bitmap域，第一标识位为Link Bitmap域中的指示位，将Link Bitmap域设置为2个字节，则可包括16个Link Bitmap指示位(即第一标识位)，标识附属AP支持16个link；其中，Link Bitmap指示位为“1”标识其对应的通信连接(即目标通信连接)将会被删除。作为第一示例，本公开实施例提供的BTM Request帧的动作域的格式如以下表1所示：
表1：
Figure PCTCN2022106310-appb-000001
Figure PCTCN2022106310-appb-000002
其中，如表1所示，在BTM Request帧中新增Link Bitmap域，将Link Bitmap域设置为2个字节或字节数可变；当Link Bitmap域设置为2个字节，则可包括16个Link Bitmap指示位，即第一标识位。
本公开实施例提供了一种通信方法，可选地，所述方法可应用于电子设备，所述电子设设备可以是多连接接入点设备AP MLD，该方法包括：
在第一无线帧中设置第一标识域，将第一标识位携带在所述第一标识域中；在所述第一无线帧中的第二标识域中设置第一子域，所述第一子域中的标识位指示所述第一标识域是否存在；
其中，所述第一无线帧中包括至少一个第一标识位，所述第一标识位指示对应的目标通信连接所属的附属AP将被删除；
在所述附属AP的至少一个通信连接下，发送所述第一无线帧。
其中，除在第一无线帧中新增第一标识域之外，还在第一无线帧的第二标识域中新增第一子域，通过第一子域指示所述第一标识域是否存在于第一无线帧中；参考上述第一示例，第一无线帧可以是基本服务集切换管理请求BTM Request帧，所述第二标识域可以是表1中的请求模式Request Mode域；在第一无线帧的第二标识域中新增第一子域，通过第一子域指示Link Bitmap域是否存在，作为第二示例，参见表2，所述第一子域包括即将删除连接Link Removal Imminent子域，则Request Mode域的格式如以下表2所示：
表2：
Figure PCTCN2022106310-appb-000003
如表2中所示，Link Removal Imminent子域占据一个比特位，Link removal imminent子域设置为“1”，则标识所述第一标识域存在于BTM Request帧中。
本公开实施例提供了一种通信方法，可选地，所述方法可应用于电子设备，所述电子设设备可以是多连接接入点设备AP MLD，该方法可以包括以下步骤：
确定第一无线帧；其中，所述第一无线帧中包括至少一个第一标识位，所述第一标识位指示对应的目标通信连接所属的附属AP将被删除
在所述附属AP的至少一个具有不支持预设功能的站点设备legacy STA的通信连接下，发送所述第一无线帧。
其中，预设功能例如802.11be协议所支持的功能；为了保证legacy STA能够解除关联，AP MLD需在已建立关联的连接下，且这个关联连接有legacy STA的情况下，发送第一无线帧，以避免legacy STA无法解除与待删除的附属AP之间的关联。
在一个可选实施例中，所述方法还包括：
在扩展能力Extended Capabilities信息元素中携带第二标识位，所述第二标识位指示所述AP MLD支持删除附属AP的能力信息。
其中，AP(例如所述AP MLD)及STA可以在Extended Capabilities中新增第二标识位，通过第二标识位标识其是否支持删除附属AP的能力；或AP及STA使用现有Extended Capabilities中的BTM(Basic Service Set Transition Management)信息位标识其是否支持删除附属AP的能力。
本公开实施例中，AP MLD确定第一无线帧，并在所述附属AP的至少一个通信连接下，发送所述第一无线帧；其中，所述第一无线帧中包括至少一个第一标识位，所述第一标识位指示对应的目标通信连接所属的附属AP将被删除。
参见图3，本公开实施例提供了一种通信方法，可选地，所述方法可应用于多连接站点设备Non-AP MLD，该方法可以包括以下步骤：
步骤301，在多连接接入点设备AP MLD的至少一个通信连接下，接收第一无线帧；其中，所述第一无线帧中包括至少一个第一标识位，所述第一标识位指示对应的目标通信连接将被删除，所述目标通信连接为所述AP MLD的待删除附属AP的通信连接。
通常情况下，AP MLD可以随时删除其附属AP；例如AP MLD主动发送所述BTM Request帧，或响应于BSS转换管理查询帧而发送；AP MLD在第一无线帧中携带第一标识位，通过第一标识位指示目标通信连接所述的附属AP将会被删除(to-be-removed)。
具体地，目标通信连接为待删除的附属AP的通信连接，这样，通过第一标识位指示附属AP将被删除，以指示该附属AP将被删除；例如，第一标识位可以是连接位图Link Bitmap域中的指示位，将Link Bitmap域设置为2个字节，则可包括16个Link Bitmap指示位(即第一标识位)，标识附属AP支持16个link；其中，Link Bitmap指示位为“1”标识其对 应的通信连接(即目标通信连接)将会被删除。
其中，所述第一无线帧中包括一个或至少两个第一标识位，每个第一标识位可以分别标识一个通信连接；这样，Non-AP MLD可以在一个通信连接下接收所述第一无线帧，通过接收一个第一无线帧确定多个通信连接将被删除，以节省信令消息，减少对网络资源的占用；Non-AP MLD还可以在至少两个通信连接下接收所述第一无线帧。
步骤302，根据所述第一标识位，解除与所述目标通信连接的关联。
Non-AP MLD根据第一标识位，确定待删除的目标通信连接，并解除与目标通信连接的关联。
在一个可选实施例中，所述第一无线帧中包括第一标识域，所述第一标识位携带在所述第一标识域中；
在一个可选实施例中，所述第一无线帧中的第二标识域中包括第一子域，所述第一子域中的标识位指示所述第一标识域是否存在。
在一个可选实施例中，所述第一标识域包括连接位图Link Bitmap域。
在一个可选实施例中，所述第一无线帧包括基本服务集切换管理请求BTM Request帧；
所述第二标识域包括请求模式Request Mode域；和/或
所述第一子域包括即将删除连接Link Removal Imminent子域。
在一个可选实施例中，所述方法还包括：
在扩展能力Extended Capabilities信息元素中携带第二标识位，所述第二标识位指示所述AP MLD支持删除附属AP的能力信息。
STA可以在第二无线帧的Extended Capabilities中新增第二标识位，通过第二标识位标识其是否支持删除附属AP的能力，第二无线帧可以是携带Extended Capabilities的无线帧；或STA使用现有Extended Capabilities中的BTM(Basic Service Set Transition Management)信息位标识其是否支持删除附属AP的能力。
在一个可选实施例中，所述方法还包括：
获取第一无线帧的解除关联计时Disassociation Timer域的时间信息， 根据所述时间信息确定每个所述目标通信连接被删除的时间；
或
获取减少邻居报告RNR信息元素中的目标信标传输时间偏移TBTT offset信息；
根据所述TBTT offset信息以及所述第一标识位，确定每个所述目标通信连接被删除的时间。
其中，如前述表1所示，第一无线帧包括解除关联计时Disassociation Timer域，Disassociation Timer域指示AP MLD向该Non-AP MLD发出Disassociation帧的时间，即Disassociation Timer域为发送第一无线帧的连接删除附属AP的等待时长；例如，Disassociation Timer域设置为目标信标传输时间(Target Beacon Transmission Time，TBTT)时间的个数，标识打算Disassociation帧之前的信标传输次数，即发送多少个TBTT beacon帧后，AP MLD会在当前连接下发送Disassociation帧，删除当前连接，则Non-AP MLD根据TBTT时间的个数，确定对应的每个所述目标通信连接被删除的时间，在所述目标通信连接被删除后，解除与目标通信连接的关联。
此外，Non-AP MLD还可以获取减少邻居报告RNR信息元素中的目标信标传输时间偏移TBTT offset信息；以第一标识域包括Link Bitmap域为例，被删除的通信连接的第一标识位将会被置“1”(或“0”)，Non-AP MLD根据第一标识位确定将被删除的其他连接，然后根据每个连接的TBTT offset时间确定该连接被删除的时间；或者，每个将被删除的连接具有一个Disassociation Timer域，Non-AP MLD统计包括多少个Disassociation Timer域，将TBTT offset时间除以Disassociation Timer域的个数，得到每个连接的TBTT offset时间，进而确定该连接被删除的时间。
本公开实施例中，Non-AP MLD在多连接接入点设备AP MLD的至少一个通信连接下，接收第一无线帧；根据所述第一标识位，解除与所述目标通信连接的关联；其中，所述第一无线帧中包括至少一个第一标识位， 所述第一标识位指示对应的目标通信连接所属的附属AP将被删除。

需要说明的是，本公开上述的计算机可读介质可以是计算机可读信号介质或者计算机可读存储介质或者是上述两者的任意组合。计算机可读存储介质例如可以是——但不限于——电、磁、光、电磁、红外线、或半导体的系统、装置或器件，或者任意以上的组合。计算机可读存储介质的更具体的例子可以包括但不限于：具有一个或多个导线的电连接、便携式计算机磁盘、硬盘、随机访问存储器(RAM)、只读存储器(ROM)、可擦式可编程只读存储器(EPROM或闪存)、光纤、便携式紧凑磁盘只读存储器(CD-ROM)、光存储器件、磁存储器件、或者上述的任意合适的组合。在本公开中，计算机可读存储介质可以是任何包含或存储程序的有形介质，该程序可以被指令执行系统、装置或者器件使用或者与其结合使用。而在本公开中，计算机可读信号介质可以包括在基带中或者作为载波一部分传播的数据信号，其中承载了计算机可读的程序代码。这种传播的数据信号可以采用多种形式，包括但不限于电磁信号、光信号或上述的任意合适的组合。计算机可读信号介质还可以是计算机可读存储介质以外的任何计算机可读介质，该计算机可读信号介质可以发送、传播或者传输用于由指令执行系统、装置或者器件使用或者与其结合使用的程序。计算机可读介质上包含的程序代码可以用任何适当的介质传输，包括但不限于：电线、光缆、RF(射频)等等，或者上述的任意合适的组合。
上述计算机可读介质可以是上述电子设备中所包含的；也可以是单独存在，而未装配入该电子设备中。
上述计算机可读介质承载有一个或者多个程序，当上述一个或者多个程序被该电子设备执行时，使得该电子设备执行上述实施例所示的方法。
根据本公开的一个方面，提供了一种计算机程序产品或计算机程序，该计算机程序产品或计算机程序包括计算机指令，该计算机指令存储在计算机可读存储介质中。计算机设备的处理器从计算机可读存储介质读取该计算机指令，处理器执行该计算机指令，使得该计算机设备执行上述各种可选实现方式中提供的方法。
可以以一种或多种程序设计语言或其组合来编写用于执行本公开的操作的计算机程序代码，上述程序设计语言包括面向对象的程序设计语言 —诸如Java、Smalltalk、C++，还包括常规的过程式程序设计语言—诸如“C”语言或类似的程序设计语言。程序代码可以完全地在用户计算机上执行、部分地在用户计算机上执行、作为一个独立的软件包执行、部分在用户计算机上部分在远程计算机上执行、或者完全在远程计算机或服务器上执行。在涉及远程计算机的情形中，远程计算机可以通过任意种类的网络——包括局域网(LAN)或广域网(WAN)—连接到用户计算机，或者，可以连接到外部计算机(例如利用因特网服务提供商来通过因特网连接)。
附图中的流程图和框图，图示了按照本公开各种实施例的系统、方法和计算机程序产品的可能实现的体系架构、功能和操作。在这点上，流程图或框图中的每个方框可以代表一个模块、程序段、或代码的一部分，该模块、程序段、或代码的一部分包含一个或多个用于实现规定的逻辑功能的可执行指令。也应当注意，在有些作为替换的实现中，方框中所标注的功能也可以以不同于附图中所标注的顺序发生。例如，两个接连地表示的方框实际上可以基本并行地执行，它们有时也可以按相反的顺序执行，这依所涉及的功能而定。也要注意的是，框图和/或流程图中的每个方框、以及框图和/或流程图中的方框的组合，可以用执行规定的功能或操作的专用的基于硬件的系统来实现，或者可以用专用硬件与计算机指令的组合来实现。
描述于本公开实施例中所涉及到的模块可以通过软件的方式实现，也可以通过硬件的方式来实现。其中，模块的名称在某种情况下并不构成对该模块本身的限定，例如，A模块还可以被描述为“用于执行B操作的A模块”。
以上描述仅为本公开的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本公开中所涉及的公开范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离上述公开构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本公开中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
