Description

数据帧传输方法、电子设备及存储介质 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数据帧传输方法、电子设备及存储介质。
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超高可靠性(Ultra High Reliability，UHR)，其愿景为提高无线局域网(Wireless Local Area Networks，WLAN)连接的可靠性、减少延迟、提高可管理性、在不同信噪比(Signal to Noise Ratio，SNR)级别下增加吞吐量并降低设备级功耗等。并且，在UHR中，为了提高系统的吞吐量，提出了在sub7GHz(吉赫兹)与45GHz和/或60GHz频段下同时进行通信的方式。
在UHR中，低时延业务传输机制将会进一步增强，且支持多连接场景。因此，需要提供一种序列号空间(Sequence Number Space，SNS)在多连接场景下的实现方式，以支持UHR。
发明内容
本公开实施例提供了一种数据帧传输方法、电子设备及存储介质，以提供一种SNS在多连接场景下的实现方式，以支持UHR。
一方面，本公开实施例提供了一种数据帧传输方法，应用于站点设备STA，所述方法包括：

在第二时刻，向第二AP发送第二数据帧；其中，第一AP与所述第 二AP维持同一个序列号空间SNS。
另一方面，本公开实施例还提供了一种数据帧传输方法，应用于接入点设备AP组，所述接入点设备组包括第一AP以及第二AP，所述方法包括：
在第一时刻，所述第一AP接收站点设备STA发送的第一数据帧；
在第二时刻，所述第二AP接收STA发送的第二数据帧；
其中，第一AP与所述第二AP维持同一个序列号空间SNS。
另一方面，本公开实施例还提供了一种电子设备，所述电子设备为站点设备STA，所述电子设备包括：

本公开实施例还提供了一种电子设备，包括存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序，处理器执行程序时实现如本公开实施例中一个或多个所述的方法。
本公开实施例还提供了一种计算机可读存储介质，该计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现如本公开实施例中一个或多个所述的方法。
本公开实施例中，STA在第一时刻，向第一AP发送第一数据帧；在第二时刻，向第二AP发送第二数据帧。其中，第一AP与所述第二AP维持同一个序列号空间SNS，这样，当STA发送单独寻址的QoS数据帧以确定QoS数据帧的序列号时，可以根据数据帧的序列号是否连续，确定是否出现数据帧丢失的情况，实现数据传输无缝衔接。
本公开实施例附加的方面和优点将在下面的描述中部分给出，这些将从下面的描述中变得明显，或通过本公开的实践了解到。

在本公开实施例中，使用的术语是仅仅出于描述特定实施例的目的，而 非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也是旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。术语“多个”是指两个或两个以上，鉴于此，本公开实施例中也可以将“多个”理解为“至少两个”。

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开实施例提供了一种数据帧传输方法、电子设备及存储介质，用以提供一种SNS在多连接场景下的实现方式，以支持UHR。
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数据帧传输方法，可选地，所述方法可应用于站点设备(Station，STA)；可选地，本公开实施例中，接入点(Access Point，AP)P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；站点设备(Station，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。
在无线局域网中，一个基本服务集(Basic Service Sets 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)。作为第一示例，参见图2，AP1与STA1构成了BSS1，AP2与STA2构成了BSS2；两个及两个以上的BSS的覆盖范围重叠，则形成重叠基本服务集(Overlapping Basic Service Sets Basic Service Set，BSS，OBSS)，如图2中，BSS1与BSS2重叠形成OBSS。
可选地，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；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3，AP MLD可以包括三个附属AP，如图3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。
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。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。
参见图1，该方法可以包括以下步骤：
步骤101，在第一时刻，向第一接入点设备AP发送第一数据帧；
步骤102，在第二时刻，向第二AP发送第二数据帧；其中，第一AP与所述第二AP维持同一个序列号空间SNS。
其中，第一数据帧和第二数据帧可以为聚合MSDU(Aggregation of the MSDUs，A-MSDU)中的MSDU；具体地，MSDU为MAC服务数据单元(MAC Service Data Unit，MSDU)，通常在介质接入控制层(Medium Access Control，MAC)，基于第一数据帧和第二数据帧具有相同的接收端地址(Receive Address，RA)以及发送端地址(Transmit Address，TA)和服务类型，将第一数据帧和第二数据帧(以及其他MSDU)聚合为一个较大的载荷形成A-MSDU，即将多个MSDU组合成一个数据帧，共享一个MAC头部。
可选地，第一数据帧和第二数据帧可以分别为服务质量(Quality of Service，QoS)数据帧。第一时刻与第二时刻可以相同也可以不同。
在第一时刻，STA向第一AP发送第一数据帧；在第二时刻，向第二AP发送第二数据帧；第一AP与第二AP可以工作在不同的连接下或相同的连接下。其中，第一AP与所述第二AP维持同一个序列号空间SNS，这样，对于STA与多个AP之间的数据传输，采用一个SNS，所寻址的数据帧的序列号为同一个序列号空间下的SN，在多连接通信的场景下，确保数据帧的有序传输。
例如，在STA由第一AP切换至第二AP的场景中，例如STA与其关联的AP通信状况发生变化时，则可以切换到另一个AP进行通信，使得数据传输不断流。其中，第一AP与所述第二AP维持同一个序列号空间SNS，这样，当STA发送单独寻址的数据帧以确定数据帧的序列号时，可以根据数据帧在两个AP分别工作的连接下的序列号，确定序列号SN是否连续，避免在切换过程中出现数据帧丢失的情况，实现数据无缝衔接。
可以理解的是，本公开实施例中，所述AP可以是AP MLD；为了便于说明，后续以AP介绍，但这并不构成对本公开实施例的限制。
具体地，仍以切换过程为例，STA向第一AP发送第一QoS数据帧，同时向第二AP发送第二QoS数据帧；第一QoS数据帧和第二QoS数据 帧具有相同的RA以及TA和服务类型。STA确定第一QoS数据帧的序列号1，并确定第二QoS数据帧的序列号2，所述第一AP与所述第二AP维持同一个序列号空间SNS；这样，在寻址时，基于同一个SNS，在两个连接下所确定的序列号1与序列号2连续，则可确定切换过程中未出现数据帧丢失的情况，STA成功由第一AP切换至第二AP。反之，所确定的序列号1与序列号2不连续，则可确定切换过程中出现数据帧丢失的情况。
本公开实施例中，STA在第一时刻，向第一AP发送第一数据帧；在第二时刻，向第二AP发送第二数据帧。其中，第一AP与所述第二AP维持同一个序列号空间SNS，这样，当STA发送单独寻址的QoS数据帧以确定QoS数据帧的序列号时，可以根据数据帧的序列号是否连续，确定是否出现数据帧丢失的情况，实现数据传输无缝衔接。本公开实施例提供了一种SNS在多连接场景下的实现方式，以支持UHR。
本公开实施例提供了一种数据帧传输方法，应用于站点设备，所述方法包括：
在第一时刻，向第一接入点设备AP发送第一数据帧；
在第二时刻，向第二AP发送第二数据帧；其中，第一AP与所述第二AP维持同一个序列号空间SNS。
其中，所述第一数据帧与所述第二数据帧在所述SNS中的索引包括：数据帧的第一发送地址以及第一接收地址；第一AP及第二AP可工作在不同的连接下，二者维持同一个序列号空间SNS，且数据帧对应的索引为(第一发送地址，第一接收地址)，以便根据索引对数据帧进行寻址。
本公开实施例提供了一种数据帧传输方法，应用于站点设备，所述方法包括：
在第一时刻，向第一接入点设备AP发送第一数据帧；
在第二时刻，向第二AP发送第二数据帧；其中，第一AP与所述第二AP维持同一个序列号空间SNS。
其中，所述第一数据帧与所述第二数据帧在所述SNS中的索引包括：数据帧的第一发送地址以及第一接收地址；第一AP及第二AP可工作在不同的连接下，二者维持同一个序列号空间SNS，且数据帧对应的索引为(第一发送地址，第一接收地址)，以便根据索引对数据帧进行寻址。
其中，所述第一接收地址包括传输标识(Traffic Identifier，TID)，TID用于标识在多条连接上传输的同一类型的数据流，例如TID中第i位置1，则表示在多条连接上传输TID为第i个比特位对应的TID的数据流。通过TID作为接收端地址，可识别第一数据帧与所述第二数据帧的数据接收端是否传输相同类型的数据流；这样，即使第一AP和第二AP可以工作在不同的连接下，接收端根据每个MSDU帧头携带的序列号(Sequence Number，SN)对多条链路上接收的相同TID的数据包按照SN进行排序,以便完整接收所有数据帧。
本公开实施例提供了一种数据帧传输方法，应用于站点设备，所述方法包括：
在第一时刻，向第一接入点设备AP发送第一数据帧；
在第二时刻，向第二AP发送第二数据帧；其中，第一AP与所述第二AP维持同一个序列号空间SNS。
其中，所述第一数据帧与所述第二数据帧在所述SNS中的索引包括：数据帧的第一发送地址以及第一接收地址。第一AP及第二AP维持同一个序列号空间SNS，且数据帧对应的索引为(第一发送地址，第一接收地址)，第一发送地址即发送端地址，例如发送端的MAC地址；第一接收地址即接收端地址，例如TID，以便根据索引对数据帧进行寻址。
具体地，数据帧对应的索引可以包括以下情况一或情况二：
情况一：所述第一接收地址包括TID；
所述第一发送地址包括所述STA的MAC地址，通过STA的MAC地址作为发送端地址，可识别第一数据帧与所述第二数据帧的数据发送端是否为同一个STA。
作为第二示例，当所述STA传输数据帧至多个AP时，SNS空间如以下表1所示：
表1：
Figure PCTCN2022139090-appb-000001
其中，SNSID为13时，SNS类型为单独寻址的QoS数据，适用的场景为STA传输数据帧至多个AP，此种场景下，索引为(地址1标识的STA所属的MAC/MLD MAC地址，TID)，地址1标识的STA所属的MAC/MLD MAC地址即所述STA的MAC地址。
情况二：至少两个所述AP协同向所述STA传输数据，所述第一发送地址包括每个所述AP的第一组MAC地址；所述第一组MAC地址包括在关联过程中，为所述AP分配的MAC地址。
可以理解的是，本公开实施例中的“协同”是指同时处于两个或以上工作状态内，共同执行某个操作；例如第一AP工作在连接1中，处于工作状态1；第二AP工作在连接2中，处于工作状态2；处于工作状态1的第一AP向STA发送数据，处于工作状态2的第二AP向STA发送数据，即可理解为“两个所述AP协同向所述STA传输数据”；也就是说，第一AP与第二AP分别向STA传输数据的操作不一定在时间上同步进行。

所述第一AP与所述第二AP维持同一个序列号空间SNS。
其中，本公开实施例提供的数据帧传输方法的所应用WLAN Sensing的架构以及WLAN Sensing过程参考前述第一示例，在此不再赘述。
其中，第一数据帧和第二数据帧可以为聚合MSDU(Aggregation of the MSDUs，A-MSDU)中的MSDU；具体地，MSDU为MAC服务数据单元(MAC Service Data Unit，MSDU)，通常在介质接入控制层(Medium Access Control，MAC)，基于第一数据帧和第二数据帧具有相同的接收 端地址(Receive Address，RA)以及发送端地址(Transmit Address，TA)和服务类型，将第一数据帧和第二数据帧(以及其他MSDU)聚合为一个较大的载荷形成A-MSDU，即将多个MSDU组合成一个数据帧，共享一个MAC头部。
可选地，第一数据帧和第二数据帧可以分别为服务质量(Quality of Service，QoS)数据帧。第一时刻与第二时刻可以相同也可以不同。
在第一时刻，第一AP接收第一数据帧；在第二时刻，第二AP接收第二数据帧；第一AP与第二AP可以工作在不同的连接下或相同的连接下。其中，第一AP与所述第二AP维持同一个序列号空间SNS，这样，对于STA与多个AP之间的数据传输，采用一个SNS，所寻址的数据帧的序列号为同一个序列号空间下的SN，在多连接通信的场景下，确保数据帧的有序传输。
例如，在STA由第一AP切换至第二AP的场景中，例如STA与其关联的AP通信状况发生变化时，则可以切换到另一个AP进行通信，使得数据传输不断流。其中，第一AP与所述第二AP维持同一个序列号空间SNS，这样，当STA发送单独寻址的数据帧以确定数据帧的序列号时，可以根据数据帧在两个AP分别工作的连接下的序列号，确定序列号SN是否连续，避免在切换过程中出现数据帧丢失的情况，实现数据无缝衔接。
具体地，仍以切换过程为例，STA向第一AP发送第一QoS数据帧，同时向第二AP发送第二QoS数据帧；第一QoS数据帧和第二QoS数据帧具有相同的RA以及TA和服务类型。STA确定第一QoS数据帧的序列号1，并确定第二QoS数据帧的序列号2，所述第一AP与所述第二AP维持同一个序列号空间SNS；这样，在寻址时，基于同一个SNS，在两个连接下所确定的序列号1与序列号2连续，则可确定切换过程中未出现数据帧丢失的情况，STA成功由第一AP切换至第二AP。反之，所确定的序列号1与序列号2不连续，则可确定切换过程中出现数据帧丢失的情况。
本公开实施例中，在第一时刻，第一AP接收第一数据帧；在第二时刻，第二AP接收第二数据帧。其中，第一AP与所述第二AP维持同一 个序列号空间SNS，这样，当STA发送单独寻址的QoS数据帧以确定QoS数据帧的序列号时，可以根据数据帧的序列号是否连续，确定是否出现数据帧丢失的情况，实现数据传输无缝衔接。本公开实施例提供了一种SNS在多连接场景下的实现方式，以支持UHR。
