在本公开实施例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实施例。在本公开实施例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。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开实施例涉及的执行主体包括但不限于：无线通信网络尤其是Wi-Fi网络如IEEE802.11a/b/g/n/ac标准下，以及下一代Wi-Fi网络中802.11be标准下的网络设备，其中，网络设备包括但不限于：Wi-Fi路由器等无线(AP，Access Point)接入点设备、无线站点(STA，Station)、用户终端、用户节点、移动终端或平板电脑等。
本公开实施例的一个应用场景为，目前，Wi-Fi技术中没有建立采用HARQ技术进行数据传输与反馈的机制。
如图1所示，本示例性实施例提供一种数据传输方法，数据传输方法可以应用于无线通信的数据帧发送端，即请求端，所述方法包括：
步骤101：生成重传反馈机制建立的请求帧，发送所述请求帧；
步骤102：接收基于所述请求帧返回的重传反馈建立的响应帧，其中，所述响应帧包含有进行重传反馈的第一配置信息。
这里，重传反馈机制包括混合自动重传请求(HARQ，Hybrid Automatic Repeat reQuest)反馈机制。请求帧可以用于在Wi-Fi通信中，发起符合HARQ传输机制要求的数据传输。
可以由Wi-Fi通信中的发送数据帧的一端，即请求端，发送请求帧。由接收数据帧的一端，即响应端，接收该请求帧，并根据该请求帧返回响应 帧。请求端和响应端可以是无线STA或无线AP等Wi-Fi通信设备。请求端和响应端之间可以基于现有的Wi-Fi协议和后续进行所述请求帧的收发。
请求帧可以用于指示响应端采用HARQ传输机制与请求端进行数据传输。响应端可以根据请求帧的格式或标识位等确定采用HARQ传输机制与请求端进行数据传输。
如图2所示的请求端和响应端的交互示意图，其中，请求端为无线站点SAT1，响应端为无线站点SAT2。如图2所示，首先由请求端发送请求帧；响应端接收到所述请求帧后，根据请求帧向请求端发送响应帧。
第一配置信息可以用于指示重传反馈的传输资源、格式等信息。其中，重传反馈可以是确认/非确认(ACK/NACK)信息，可以采用位图等形式反馈数据帧的接收情况。
HARQ传输机制进行重传反馈的步骤，如图2所示，可以包括：
步骤21：请求端发送请求帧；
步骤22：响应端根据请求帧内容返回响应帧；
步骤23：请求端发送数据帧；
步骤24：响应端根据数据帧的接收情况发送重传反馈。
接收到重传反馈后，请求端可以重传根据重传反馈确定的未成功接收的数据帧；响应端采用重发的数据帧进行解析或合并解析。
通过请求帧和响应帧在请求端和响应端之间建立重传反馈连接，一方面，响应帧提供了重传反馈的配置信息，为请求端处理重传反馈提供指示，提高请求端处理重传反馈的效率；另一方面，通过建立重传反馈连接，可以为后续数据重传提供重传依据，提高数据传输纠错能力。
在一个实施例中，所述第一配置信息包括以下至少之一：所述重传反馈的反馈方式信息，其中，所述反馈方式信息，用于指示进行基于数据帧和/或基于数据块的接收反馈；所述重传反馈的资源信息，其中，所述资源信息包括：时间信息和/或频段信息；触发所述重传反馈的触发帧信息，其中，所述触发帧信息至少包含：触发帧的发送方式和/或发送时间信息。
这里，重传反馈的反馈方式信息可以用于向请求端指示重传反馈的反馈形式。其中，基于数据帧的接收反馈，可以是针对单个数据帧的反馈；例如：针对单数据帧的反馈。基于数据块的接收反馈，可以是分别针对连续数据帧中多个子数据帧的反馈，可以采用位图等形式指示连续数据帧中 每个子数据帧的接收情况。可以在位图中用“1”表示对应的子数据帧成功接收，用“0”表示对应的子数据帧未成功接收。请求帧中请求发送的数据类型如果是连续数据帧，则响应端可以采用基于数据块的接收反馈，进行重传反馈。通过请求帧建立连续数据帧的HARQ传输机制，并实现基于数据块的接收反馈对连续数据帧进行重传反馈。
响应端可以根据请求帧中请求的数据帧类型，确定反馈方式信息。当请求帧请求发送单数据帧时，反馈方式信息可以指示进行基于数据帧的接收反馈。当请求帧请求发送连续数据帧时，反馈方式信息可以指示进行基于数据块的接收反馈。
当所述反馈方式信息指示进行基于数据帧的接收反馈时，请求端可以根据接收的重传反馈确定单个数据帧的接收情况；当所述反馈方式信息指示进行基于数据块的接收反馈时，请求端根据接收的重传反馈确定连续数据帧中多个子数据帧的接收情况。
重传反馈的资源信息可以用于向请求端指示重传反馈的传输资源。
重传反馈的资源信息中的时间信息可以是传输重传反馈的时域资源。重传反馈的资源信息中的频段信息可以是传输重传反馈的频域资源。请求端可以在资源信息指示的传输重传反馈的时域和/或频域资源上，接收响应端发送的重传反馈。
重传反馈也可以采用触发帧的方式进行触发，请求端可以发送触发帧触发响应端发送重传反馈。响应端可以通过响应帧指示请求端发送触发帧的发送方式和/或发送时间信息。请求端根据该触发帧的发送方式和/或发送时间信息发送触发帧，触发响应端发送重传反馈。
第一配置信息提供了重传反馈的传输资源、反馈内容和触发方式等，如此，请求端可以根据第一配置信息提供的指示信息触发、接收和解码重传反馈提高请求端处理重传反馈的效率。
在一个实施例中，所述方法还包括：根据所述第一配置信息，接收所述重传反馈。
请求端在接收到响应帧后，向响应端发送数据帧。响应端接收到数据帧后，将接收结果通过重传反馈向请求端进行反馈。
请求端可以根据第一配置信息指示的资源，或采用第一配置信息指示的接收方式等接收重传反馈。
在一个实施例中，所述根据所述第一配置信息，接收所述重传反馈，包括：在所述资源信息指示的时间和/或频率上接收所述重传反馈。
重传反馈的资源信息中的时间信息可以是传输重传反馈的时域资源。重传反馈的资源信息中的频段信息可以是传输重传反馈的频域资源。请求端可以在重传反馈的资源信息指示的传输重传反馈的时域和/或频域上，接收响应端发送的重传反馈。如此，可以准确接收重传反馈。
在一个实施例中，所述在根据所述资源信息指示的时间上接收所述重传反馈，包括：在发送数据帧之后的第一个信标帧后，接收所述重传反馈。
无线STA或无线AP等Wi-Fi通信设备会周期性地向外发送信标帧，用于同步或指示无线网络的存在。
这里，所述资源信息指示的时间可以是发送数据帧之后的第一个信标帧。请求端可以在发送数据帧之后的第一个信标帧后接收重传反馈。
在一个实施例中，所述在发送数据帧之后的第一个信标帧后，接收所述重传反馈，包括：在发送所述数据帧之后的所述第一个信标帧后，发送所述触发帧；接收基于所述触发帧触发的所述重传反馈。
具体的，如图2所示，请求端可以在数据帧发送完后的第一个信标帧后，采用触发的方式触发响应端发送重传反馈。触发的方式可以通过向响应端发送触发帧。触发帧的内容可以预先在请求端和响应端之间商定。
响应端接收到触发帧后，可以根据第一配置信息中的重传反馈传输资源向请求端发送重传反馈。
在一个实施例中，所述触发帧的发送方式：包括：竞争发送所述触发帧或在预设时间点发送所述触发帧。
竞争发送可以指采用分布式控制功能(DCF，Distributed control function)，在确定传输所述触发帧的信道空闲时，发送所述触发帧。请求端可以侦听用于发送触发帧的信道，当信道中的链路处于闲置状态，并在等待可能出现报文间隔时间后，发送触发帧。
请求端也可以预设时间点，在预设时间点发送所述触发帧，触发响应端发送重传反馈。
在一个实施例中，所述请求帧包括：请求进行数据帧传输的第二配置信息。
请求端需要向响应端发送数据帧，在发送数据帧之前，可以通过请求 帧向响应端发送请求进行数据帧传输的第二配置信息。

其中，所述通信时长为：所述请求帧的传输时长、和所述响应帧的传输时长、和数据帧的传输时长、和N个预定类型帧间间隔时长相加之和，其中，N为不小于2的正整数。
这里，可以由进行数据帧传输的两端以外的STA或AP等Wi-Fi设备，执行所述数据传输方法的步骤。
在Wi-Fi通信数据帧传输中，由发送数据帧的一端，即请求端，发送请求帧。由接收数据帧的一端，即响应端，接收该请求帧，并根据该请求帧返回响应帧。接收到重传反馈后，请求端可以重传根据重传反馈确定的未成功接收的数据帧；响应端采用重发的数据帧进行解析或合并解析。
Wi-Fi技术对物理层上来说，所有的发送都是广播，单播与否只是在链路层以上分辨的。发送请求帧的时候，可以通过请求帧中的第一持续信息位告诉接收到请求帧的STA，在未来的一段时间内，链路被占用，以完成整个通信过程。这样，其它STA在此期间就不会发送数据干扰本次的通信。其中，第一持续信息位指示的时间也可以称为持续时间(Duration)。
在整个HARQ传输机制的数据传输过程中，请求端需要发送请求帧，接收响应帧和发送数据帧。因此，可以将请求帧的传输时长、响应帧的传输时长和数据帧的传输时长，以及请求帧、响应帧、数据帧之间的2个间隔时长确定为请求端占用信道的最小持续时间。可以将占用信道的最小持续时间确定为持续时间，也可以通过加入间隔时长的方法增加持续时间。预定类型帧间间隔时长可以是短帧间间隔时长。其中，请求帧中可以设置第一持续信息位，用于指示请求端占用信道时长。

在请求端和响应端占用信道的通信时长内，其它Wi-Fi设备不能占用信道。通信时长可以根据请求帧的第一持续信息位和响应帧的第二持续信息位，确定请求端和响应端占用信道的通信时长。
可以去请求端和响应端占用信道的通信时长的最大值，作为其他STA不占用信道的时间。其他STA不占用信道的时间可以是：所述请求帧的传输时长、和所述响应帧的传输时长、和数据帧的传输时长、和至少2个预定类型帧间间隔时长相加之和。预定类型帧间间隔时长可以是短帧间间隔时长。
如此，可以保证在请求端和响应端进行整个HARQ传输期间，其他STA不占用信道。提高数据传输稳定性。
由于HARQ传输机制采用延时的重传反馈，因此，通信时长中可以不包含重传反馈的传输时长。
以下结合上述任意实施例提供一个具体示例：
1、STA在发送数据之前，如需建立HARQ机制进行数据帧的反馈，则发送HARQ机制建立请求帧，其建立流程图如图2所示：

整个HARQ建立请求帧隐含的标识了接收数据帧的确认/数据块确认(ACK/Block ACK)的方式为延迟的ACK，具体接收时延在HARQ建立响应帧中做出规定。
HARQ的持续(duration)字段的设置为：自身时长，加上将要发送数据帧时长(单数据帧/连续数据帧)，再加上响应帧时长，最后加上2SIFS
2、回复HARQ机制建立响应消息帧。
