具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
本公开提供的数据传输方法应用于包括数据发送端和数据接收端的无线局域网通信系统中。数据发送端和数据接收端可为站点(Station，STA)或接入点(Access Point，AP)。数据发送端与数据接收端之间通过无线局域网执行数据的前向传输和回传。
其中，本公开中涉及的STA可以理解为是无线局域网中的用户终端，该用户终端可以称为用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、物联网(Internet of Things，IoT)客户端或者车载设备等。
本公开中涉及的AP指无线局域网用户终端接入网络的设备、路由器等。
相关技术中，STA和AP之间采用IEEE802.11标准进行数据包传输。目前，IEEE802.11成立了SG(study group)IEEE802.11be来研究下一代主流(802.11a/b/g/n/ac/ax)Wi-Fi技术，所研究的范围为：320MHz的带宽传输，多个频段的聚合及协同等，所提出的愿景相对于现有的IEEE802.11ax提高至少四倍的速率以及吞吐量。其主要的应用场景 为视频传输，AR、VR等。
其中，多个频段的聚合及协同是指同时在多个频段或同一频段中多个带宽进行数据传输，例如同时在2.4GHz、5.8GHz及6-7GHz三个频段下进行数据传输。同时在多个频段或同一频段中多个带宽中进行数据传输可以理解为是多连接数据传输。
本公开提供一种数据传输方法，数据发送端生成待传输数据帧，并在一个或多个频段中传输生成的数据帧，且一个或多个频段中每一频段具有相同的序列号，该相同的序列号(Sequence Number，SN)用于标识待传输的数据帧。本公开中，通过在一个或多个频段中传输生成的数据帧，并为每一频段分配用于标识数据帧的相同序列号，实现多连接数据传输，进而提高数据传输时的吞吐量，并提高频谱有效利用率。
图1是根据一示例性实施例示出的一种数据传输方法的流程图，如图1所示，数据传输方法用于数据发送端中，数据发送端可以是STA或AP，包括以下步骤。
在步骤S110中，生成待传输数据帧。
本公开中，待传输数据帧可为单数据帧或连续传输的多数据帧。
在步骤S120中，在一个或多个频段中传输数据帧。
本公开中，一个或多个频段中每一频段具有相同的序列号，序列号用于标识待传输数据帧。
本公开中，若待传输数据帧为单数据帧，则一个或多个频段中传输具有相同序列号的单数据帧的数据分块。若待传输数据帧为连续传输的多数据帧，则一个或多个频段中传输具有相同序列号的多数据帧的数据子帧，且每一数据子帧具有各自对应的子帧编号。
本公开中，一方面，传输单数据帧中各数据分块的频段为具有不同频率的多个频段。另一方面，传输单数据帧中各数据分块的频段为具有不同频率带宽的同一频段，每一频段中设置的带宽频率可相同或不同。例如，假设每一频段中设置的带宽频率不同，则在2.4GHz频段下设置的带宽频率为20MHz，在5.8GHz频段下设置的带宽频率为40MHz，在6-7GHz频段下设置的带宽频率为80MHz。或假设每一频段中设置的带宽频率相同，则在2.4GHz频段下、在5.8GHz频段下、在6-7GHz频段下设置的带宽频率均为20MHz、或40MHz、或80MHz。
本公开中，连续传输的多数据帧的数据子帧的频段为具有不同频率的多个频段，或连续传输的多数据帧的数据子帧的频段为具有不同频率带宽的同一频段，每一频段中设置的带宽频率可相同或不同。例如，假设每一频段中设置的带宽频率不同，则在2.4GHz频段下设置的带宽频率为20MHz，在5.8GHz频段下设置的带宽频率为40MHz，在6-7GHz 频段下设置的带宽频率为80MHz。或假设每一频段中设置的带宽频率相同，则在2.4GHz频段下、在5.8GHz频段下、在6-7GHz频段下设置的带宽频率均为20MHz、或40MHz、或80MHz。
本公开中，通过本公开的数据传输方法，满足多连接通信中为数据帧分配序列号的要求，也满足IEEE802.11be标准的需求，使得数据发送端与接收端之间实现多连接数据传输，提高系统在数据传输时的吞吐量。同时，减少了数据传输过程中占用频段或一个频段中不同带宽的时间，进而提高了频谱有效利用率。
图2是根据一示例性实施例示出的传输单数据帧中各数据分块的频段为具有不同频率的、多个频段的数据传输方法的流程图。如图2所示，数据传输方法用于数据发送端中，包括步骤S210至步骤S220。
在步骤S210中，生成待传输单数据帧。
在步骤S220中，在多个频段中按照频率高低顺序，顺序传输单数据帧中的各数据分块，不同的频段传输不同的数据分块。
本公开一示例中，假设数据发送端在三个频段中进行数据传输，每个频段的频率大小由低至高为2.4GHz、5.8GHz及6-7GHz。在这三个频段下数据发送端为每一频段设置相同的序列号1。由于在三个频段中进行数据传输，因此将单数据帧分为三个数据分块，那么每一数据分块的序列号均为1，并为每一数据分块编号，例如为：数据分块1、数据分块2及数据分块3。而数据分块编号、序列号的通过序列控制字段标注。如图3为序列控制字段标注数据分块编号及序列号的示意图，如图3所示，数据分块编号通过序列控制字段的前4个字节标注，序列号通过序列控制字段的5至12个字节标注。
本公开中可在多个频段中按照频率由高至低或由低至高的顺序，顺序传输单数据帧中具有编号的各数据分块。例如：在2.4GHz频段传输数据分块1，在5.8GHz频段传输数据分块2，在6-7GHz频段传输数据分块3。或在2.4GHz频段传输数据分块3，在5.8GHz频段传输数据分块2，在6-7GHz频段传输数据分块1。
一种实施方式中，数据接收端接收到数据发送端发送的数据分块后，对数据分块进行解码。在解码失败时会向数据发送端反馈数据分块解码失败反馈消息。数据分块解码失败反馈消息中包括有解码失败的数据分块初始传输的序列号。以使数据发送端在重传解码失败的数据分块至数据接收端时，携带初始传输的序列号。
在图2所示的传输单数据帧中各数据分块的频段为具有不同频率的、多个频段的数据传输方法中，还可包括如下步骤：
在步骤S230中，在接收到数据分块解码失败反馈时，重传解码失败的数据分块。
本公开中，重传的数据分块具有与初始传输数据分块相同的序列号。

本公开中，假设数据发送端在每一不同频率带宽中按照频率由高至低的顺序，顺序传输具有子帧编号的数据子帧，那么数据接收端在每一不同频率带宽中按照频率由高至低的顺序，顺序接收具有子帧编号的数据子帧。例如，数据发送端在2.41GHz～2.43GHz频率带宽传输第一部分数据子帧，在2.44GHz～2.46GHz频率带宽传输第二部分数据子帧，在2.47GHz～2.49GHz频率带宽传输第三部分数据子帧。那么数据接收端在2.41GHz～2.43GHz频率带宽接收第一部分数据子帧，在2.44GHz～2.46GHz频率带宽接收第二部分数据子帧，在2.47GHz～2.49GHz频率带宽传输第三接收数据子帧，并按照接收的每一部分数据子帧的顺序及每一部分数据子帧的编号顺序，顺序解码数据子帧。

在步骤S1230中，数据接收端若对数据帧解码失败，则发送数据帧解码失败反馈消息。数据发送端接收数据接收端发送的数据帧解码失败反馈消息。
本公开中，在数据帧解码失败时，根据解码失败的数据帧类型反馈对应的数据帧解码失败反馈消息。例如，在数据帧为单数据帧时，若数据接收端解码数据分块失败，则发送数据分块解码失败反馈消息至数据发送端。在数据帧为多数据帧时，若接收端解码数据子帧失败，则发送数据子帧解码失败反馈消息。
