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IEEE802.11be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，现有的IEEE802.11标准中，设备接收ACK的最短时长为一个短帧间间隔(SIFS，short inter-frame space)，在2.4GHz下为SIFS为10us，在5GHz频段下SIFS为16us。由于数据帧接收端处理速度的原因，数据帧接收端可能无法在10us或16us之内完成数据帧解码，并将数据帧的接收反馈信息发送给数据帧发送端。
如图1所示，本示例性实施例提供一种接收反馈信息传输配置方法，接收反馈信息传输配置方法可以应用于无线通信的数据帧发送端，所述方法包括：
步骤101：生成针对采用多个传输频段传输数据帧的请求发送帧，其中，所述请求发送帧包括：反馈资源信息，其中，所述反馈资源信息，用于指示数据帧接收端传输接收反馈信息的传输资源；
步骤102：发送所述请求发送帧。
这里，无线通信可以是采用IEEE802.11be等标准的Wi-Fi通信；数据帧发送端和数据帧接收端可以是Wi-Fi通信中的无线站点(STA，Station) 等。数据帧可以是在多个传输频段中的各传输频段中分别进行传输的数据帧。数据帧可以是媒体存取控制协议数据帧(MPDU，Media Access Control Protocol Data Unit)或聚合媒体存取控制协议数据帧(A-MPDU，Aggregation Media Access Control Protocol Data Unit)等。
多个传输频段可以是多个Wi-Fi工作频段，如2.4GHz、5.8GHz及6-7GHz等；也可以是传输频段占用的带宽的频率范围。其中，各传输频段占用的带宽的频率范围可以属于同一个Wi-Fi工作频段，也可以属于不同Wi-Fi工作频段。
数据帧由数据帧发送端利用多个传输频段进行发送，并由数据帧接收端进行接收。数据帧接收端可以是Wi-Fi通信中的无线站点等。这里，多个传输频段的频率覆盖范围不同，多个传输频段可以同时进行数据帧的传输，进而提高数据帧的传输速率，提高数据帧传输效率。
接收反馈信息可以是用于反馈数据帧接收状况的确认(ACK)或非确认(NACK)，也可以是用于反馈连续数据帧接收状况的块确认(Block ACK)信息等。
在进行数据传输前，数据帧发送端和数据帧接收端首先会根据传输协议进行握手，握手流程可包括：由数据帧发送端发送请求发送帧(RTS，Request To Send)，表明数据帧发送端要向数据帧接收端发送数据帧。数据帧接收端接收到请求发送帧后向数据帧发送端发送允许发送帧(CTS，Clear To Send)。
这里，可以在请求发送帧中携带反馈资源信息，用于向数据帧接收端指示传输接收反馈信息的传输资源。其中，传输资源可以是用于传输接收反馈信息的时域资源和/或频域资源，传输资源信息也可以是发送数据帧频段中的一个频段中的时域资源和/或时频资源。示例性的，反馈资源信息指示的时域资源可以是数据帧接收端接收数据帧并且完成解调及解码等处理 后的时间段。如此，可以减少发送接收反馈信息时，数据帧接收端没有完成数据帧解码的情况。
数据帧接收端在接收到请求发送帧中携带的反馈资源信息后，接收数据帧，对数据帧进行解调及解码等处理。确定数据帧的接收状况，并利用反馈资源信息指示的传输资源向数据帧发送端发送接收反馈信息。
如此，采用反馈资源信息指示传输接收反馈信息的传输资源，一方面，发送方通过所述请求发送帧的发送实现根据实际情况调整传输资源，提高接收反馈信息传输资源配置的灵活性。另一方面，不再采用固定的时间和/或频段发送接收反馈信息，可以减少发送接收反馈信息时，数据帧没有完成解码的情况，提高接收反馈信息的准确性。
在一个实施例中，所述反馈资源信息，包括以下至少之一：反馈频段信息，用于指示数据帧接收端传输所述接收反馈信息的反馈传输频段；反馈时间区间信息，用于指示所述数据帧接收端传输所述接收反馈信息的反馈时间区间。
这里，反馈传输频段可以是多个传输频段中的一个频段。反馈传输频段可以在传输完数据帧后用于传输接收反馈信息。反馈传输频段可以是多个传输频段中的一个频段。反馈传输频段可以在传输完数据帧后，用于传输接收反馈信息。
反馈时间区间可以是在数据帧接收端完成数据帧解码后的时间段。如此，可以在确定数据帧接收状况后再发送接收反馈信息，减少接收反馈信息出现错误的几率。
在一个实施例中，所述传输所述接收反馈信息的反馈时间区间，包括：所述数据帧发送后的1个点协调功能帧间间隔时长(PIFS，Point coordination function Inter Frame Space)至100毫秒。
数据帧可以包括单播数据帧和连续数据帧。当数据帧为连续数据帧时， 数据帧发送后的1个点协调功能帧间间隔时长至100毫秒可以是连续数据帧的最后一个子数据帧发送后的1个点协调功能帧间间隔时长至100毫秒。
短帧间间隔(SIFS，Short Inter-Frame space)用于间隔一次数据传输中各个帧，如间隔数据帧，ACK帧等。相关技术在数据帧和接收反馈信息之间仅间隔一个SIFC，数据帧接收端没有足够的时间完成数据帧的解析，从而无法发送可以反应数据帧真实接收状况的接收反馈信息。相对于短帧间间隔，Wi-Fi通信中还包括点协调功能帧间间隔，点协调功能帧间间隔通常用于具有点协调功能(PCF Point coordination function)的无线访问节点(AP)，具有PCF的AP通常间隔一个点协调功能帧间间隔时长访问信道。。PIFS时长的是SIFS时长加一个时隙时间(Slot Time)。这里，在数据帧后间隔1个点协调功能帧间间隔再发送接收反馈信息，可以为数据帧接收端提供较为充足的时间进行解码等处理，从而数据帧接收端可以发送反应数据帧真实接收状况的接收反馈信息。因此，在数据帧发送后的1个点协调功能帧间间隔时长至100毫秒这个时间段内发送接收反馈信息，可以减少数据帧没有完成解码，从而接收反馈信息出现错误的几率。100毫秒的最长时间限制，可以提供反馈时间上限，提高接收反馈信息反馈的效率。
在一个实施例中，所述方法还包括：根据反馈资源信息，接收数据帧接收端发送的所述接收反馈信息。
所述根据反馈资源信息，接收数据帧接收端发送的所述接收反馈信息，包括：
利用所述反馈资源信息指示的反馈传输资源，接收数据帧接收端发送的所述接收反馈信息。
数据帧接收端在接收到请求发送帧中携带的反馈资源信息后，接收数据帧，对数据帧进行解调、解码等处理。确定数据帧的接收状况，并利用反馈资源信息指示的传输资源向数据帧发送端发送接收反馈信息。
在一个实施例中，在发送所述请求发送帧之前，所述方法还包括：根据每个所述传输频段的负载情况，确定传输所述接收反馈信息的所述反馈传输频段。
在利用多个传输频段传输数据帧时，各个传输频段的负载可能不相同。示例性的，可以采用负载较小的传输接收反馈信息。
根据每个所述传输频段传输所述数据帧的收发时间划分，数据帧的传输可以分为同步传输和异步传输。示例性的，同步传输如图2a所示，各传输频段的数据帧的发送时间和到达接收端的时间均相同。异步传输如图2b至图2d所示，异步传输有三种情况：
第一种：如图2b所示，各传输频段数据帧的发送时间相同，到达接收端的时间不相同。
第二种：如图2c所示，各传输频段数据帧的发送时间不相同，到达接收端的时间也不相同。
第三种：如图2d所示，各传输频段数据帧的发送时间不相同，到达接收端的时间相同。数据帧到达接收端的时间可以由发送端根据数据帧的发送时间和数据帧长度等确定。
在一个实施例中，所述根据每个所述传输频段的负载情况，确定传输所述接收反馈信息的所述反馈传输频段，包括以下至少之一：
将负载值最低的所述传输频段，确定为所述反馈传输频段；
将建立连接的无线站点数量最少的所述传输频段，确定为所述反馈传输频段。
每个传输频段都有一个负载(Load)值，可以通过读取负载值等方式确定传输频段的负载情况。由于传输接收反馈信息需要占用一定的资源，因此，可以在负载最低的传输频段传输接收反馈信息，如此，可以充分利用低负载的传输频段，相对于采用负载高的传输频段发送数据，一方面能 够不用进行负载排队，能够及时传输；另一方面，负载较低的传输频率允许较低的码率，能够通过低码率确保传输质量。
与传输频段建立关联连接的无线站点数量越多，则传输频段出现较高负载的概率越大；与传输频段建立关联的无线站点数量越少，则传输频段出现较高负载的概率相对较小；因此，可以在建立关联的无线站点数量最少的传输频段传输接收反馈信息，提高在低负载传输频段进行接收反馈信息传输的概率，提高传输频段的利用效率。
在一个实施例中，所述方法还包括：利用所述多个传输频段传输所述数据帧；所述数据帧包含的持续时间域指示的持续时间包括：所述数据帧的传输时长且不包括接收反馈信息的传输时长。
这里，数据帧发送端可以采用多个传输频段发送数据帧。数据帧接收端可以在多个传输频段接收数据帧。由于接收反馈信息利用请求发送帧中指定的反馈资源进行传输。因此，数据帧的持续时间域(Duration)可以不包括接收反馈信息的传输时长。
在一个实施例中，当所述数据帧为单播数据帧时，所述数据帧的传输时长包括：单个所述单播数据帧的传输时长；
当所述数据帧为连续数据帧时，所述数据帧的传输时长包括：所述连续数据帧所包含的n个子数据帧的传输时长与n-1个短帧间间隔之和，其中，n为等于或大于2的正整数，其中，所述短帧间间隔位于相邻两个所述子数据帧之间。
数据帧可以包括单播数据帧和连续数据帧。这里，单播数据帧传输是指将数据封装在一个数据帧中传输的形式，一个单播数据帧具有一个接收反馈信息。连续数据帧传输是指将数据封装在多个子数据帧中并按序传输的形式，连续数据帧可以采用块接收反馈信息(Block ACK)的形式进行接收反馈，块接收反馈信息可以采用包括多个反馈信息，每个反馈信息分别 用于指示每个子数据帧的接收状况。
当数据帧为单播数据帧时，持续时间域指示的数据帧传输时长可以是单播数据帧的传输时长。当数据帧为连续数据帧时，持续时间域指示的数据帧传输时长可以是连续数据帧中每个子数据帧的传输时长与各子数据帧之间短帧间间隔之和。
