附图说明

图9是根据本公开的实施例示出的一种用于接收状态反馈的装置的示意框图。
具体实施方式
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，而不是全部的实施例。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。
图1是根据本公开的实施例示出的一种接收状态反馈方法的示意流程图。本公开实施例所示的接收状态反馈方法，可以适用于Wi-Fi网络中的接收端，其中，所述接收端可以是无线接入点(Access Point，简称AP)，例如路由器，所述接收端也可以是站点(Station，简称STA)，例如手机，平板电脑，可穿戴设备等电子设备。例如在无线接入点向站点发送数据帧时，无线接入点作为传输端，站点作为接收端，而在站点向无线接入点发送数据帧时，站点作为传输端，无线接入点作为接收端。
如图1所示，所述接收状态反馈方法可以包括以下步骤：
在步骤S1中，接收传输端在n个频段同时发送的数据帧，其中，n＞1；
在步骤S2中，根据在所述n个频段接收数据帧的接收状态生成反馈信息帧，其中，所述反馈信息帧包括至少n组预设比特位，所述n组预设比特位用于指示在所述n个频段接收数据帧的接收状态；
在步骤S3中，向所述传输端发送所述反馈信息帧。
在一个实施例中，传输端可以在n个频段聚合的情况下，在n个频段同时向接收端发送数据帧，例如传输端需要向接收端发送一个视频，可以将该视频划分为n个部分，然后同时在n个频段发送n个部分，则n个部分可以一起被发送给接收端，并且每个部分相对于原视频而言数据量较小，因此在每个频段下传输所需的时间较少，从而可以更快地将完整个视频发送给接收端，其中，n个频段包括但不限于2.4GHz频段，5.8GHz频段，6-7GHz频段。并且在每个频段发送的数据帧可以是不同的，据此，可以提高数据帧的收发速度，也可以在每个频段发送相同的数据帧，据此，可以提高接收端接收数据帧的成功率。
图2是相关技术中接收端向传输端反馈的信息的示意图。
在相关技术中，传输端在同一时刻下只在一个频段向接收端发送数据帧，如图2所示，接收端向传输端反馈的信息中包括FC(frame control，帧控制)字段，RA(receiver address，接收地址)字段，TA(transmitter address，传输地址)字段，FCS(frame check sequence，校验序列)字段。
具体地，相关技术中的接收端在FC字段中记载对于数据帧的接收状态，从而使得传输端接收到反馈的信息后，可以基于FC字段确定接收端对于数据帧的接收状态。但是，由于FC字段的比特位有限，而且FC字段还需要记载其他信息，所以现有 技术中在FC字段中记载接收状态的方式，只能记载很少的信息，仅适用于传输端在同一时刻下只在一个频段向接收端发送数据帧的情况(所要的比特位较少)，并不适用于传输端在n个频段同时向接收端发送数据帧的情况(所要的比特位较多)。
根据本公开的实施例，传输端在n个频段同时向接收端发送数据帧，接收端可以在n个频段同时接收传输端所发送的数据帧，进而基于在n个频段中每个频段对于数据帧的接收状态，可以生成包括至少n组预设比特位的反馈信息帧，在反馈信息帧中的n组预设比特位记载在n个频段中每个频段对于数据帧的接收状态，从而使得传输端可以确定接收端对于n个频段中每个频段的数据帧的接收状态。
传输端根据确定的接收状态，可以确定后续操作，例如确定接收端在某个频段下接收数据帧失败，那么后续可以重新向接收端发送该数据帧。
图3是根据本公开的实施例示出的一种反馈信息帧的示意图。
如图3所示，每组预设比特位可以包括一个预设比特位，那么反馈信息帧可以包括n个预设比特位，每个预设比特位的值可以是“0”或“1”，其中，可以用1表示对于数据帧的接收状态为成功(例如接收到数据帧)，用0表示对于数据帧的接收状态为失败(例如未接收到数据帧)，进而可以通过n个预设比特位指示在n个频段接收数据帧的接收状态。
例如可以通过第i个预设比特位表示在第i个频段(例如标识或序号为i的频段)接收数据帧的接收状态，如图3所示，第1个预设比特位值为0，可以表示在第1个频段接收数据帧的接收状态为失败，第2个预设比特位值为1，可以表示在第2个频段接收数据帧的接收状态为成功，第3个预设比特位值为0，可以表示在第3个频段接收数据帧的接收状态为失败，以此类推，通过n个预设比特位即可指示在n个频段接收数据帧的接收状态。进而接收端在接收到该反馈数据帧后，可以根据n个预设比特位即可指示在n个频段接收数据帧的接收状态。
更进一步地，在n组预设比特位的长度小于8的整数倍时，可以补充值为0的额外比特位，使得预设比特位与额外比特位之和等于8的整数倍，也即使得预设比特位和额外比特位之和为字节长度的整数倍，并且反馈信息帧中其他字段也为字节长度的整数倍，因此便于进行传输。例如在图2所示的实施例中，n组预设比特位的长度为3，用于指示在3个频段接收数据帧的接收状态，其长度为3，小于8的整数倍，可以补充5个额外比特位，例如n组预设比特位具体为“010”，补充的额外比特位为 “00000”，那么预设比特位和额外比特位连起来就是“01000000”，指示在第1频段、第3频段下的数据帧的接收状态为失败，而在第2频段下的数据帧的接收状态为成功。
需要说明的是，n组预设比特位可以如图3所示位于TA字段和FCS字段之间，也可以根据需要设置位移其他位置。
并且反馈信息帧中除了可以如图3所示包括FC字段，RA字段，TA字段和FCS字段，也可以根据需要在反馈信息帧中配置其他字段。
其中，FC字段可以用于指示反馈信息帧的类型等信息，RA字段可以指示接收反馈信息帧的设备的接收地址，TA字段可以指示接收发送反馈信息帧的设备的发送地址，例如接收端向传输端发送该反馈信息帧，那么RA字段可以记载传输端的地址，TA字段可以记载接收端的地址，FCS字段则可以起到校验的作用。
可选地，每组预设比特位包括一个预设比特位，n个所述预设比特位中第i个预设比特位用于指示在所述n个频段中第i个频段接收数据帧的接收状态，1≤i≤n。
在一个实施例中，接收端和传输端可以预先约定反馈信息帧中n个预设比特位中第i个预设比特位的值与n个频段中第i个频段接收数据帧的接收状态相关联，进而接收端可以通过n个预设比特位中第i个预设比特位向传输端指示在n个频段中第i个频段接收数据帧的接收状态，例如图3所示，第1个预设比特位用于指示在第1个频段接收数据帧的接收状态，第2个预设比特位用于指示在第2个频段接收数据帧的接收状态，第3个预设比特位用于指示在第3个频段接收数据帧的接收状态。
据此，可以通过n个预设比特位来指示在n个频段中接收数据帧的接收状态，从而n组预设比特位仅包括n个预设比特位，进而使得反馈信息帧包含的预设比特位较少，有利于减少反馈信息帧的数据量，以便降低接收端向传输端发送反馈信息帧的通信负担。
可选地，所述数据帧包括k段子数据帧，所述接收端分k次发送所述k段子数据帧；
其中，每组预设比特位包括k个预设比特位，在所述n组预设比特位中的第i组预设比特位中，所述k个预设比特位用于指示在所述n个频段中第i个频段接收所述k段子数据帧的接收状态，k＞1，1≤i≤n。
图4是根据本公开的实施例示出的另一种反馈信息帧的示意图。
在一个实施例中，传输端可以将在每个频段下发送的数据帧都划分为k段子数据帧，然后在每个频段都分k次向接收端发送k段子数据帧，而在每个频段发送子数据帧的动作是同时的。
在这种情况下，接收端生成的反馈信息帧中，每组预设比特位可以包括k个预设比特位，然后通过n组预设比特位中的第i组预设比特位中的k个预设比特位，指示在n个频段中第i个频段接收k段子数据帧的接收状态，以便传输端能够基于反馈信息帧确定接收端对于n个频段中每个频段下子数据帧的接收状态。
例如传输端在每个频段下发送的数据帧都包括2个子数据帧，那么图4所示，k每组预设比特位包括2个预设比特位，也即k＝2，其中，第1组预设比特位中的第1个预设比特位为0，表示在第1个频段下接收第1个字数据帧的接收状态为接收失败，第2组预设比特位中的第2个预设比特位为1，表示在第2个频段下接收第2个字数据帧的接收状态为接收成功。
需要说明的是，数据帧包括的k段子数据帧，具体的k值可以由传输端和接收端协商确定，也可以是传输端或接收端的用户预先设定的。
可选地，每组预设比特位中的第一部分预设比特(可以称作traffic identifier，简称TID)位用于指示接收数据帧所在的目标频段信息，每组预设比特位中的第二部分预设比特位用于指示在所述目标频段接收数据帧的接收状态。
图5是根据本公开的实施例示出的又一种反馈信息帧的示意图。
在一个实施例中，可以将每组预设比特位划分为两部分，通过其中的第一部分预设比特位指示接收数据帧所在的目标频段信息，通过其中的第二部分预设比特位指示在目标频段接收数据帧的接收状态，在这种情况下，可以不限于通过第i组预设比特位指示第i个频段接收数据帧的接收状态，而是可以通过任一组预设比特位指示第i个频段接收数据帧的接收状态，提高了设置反馈信息帧的灵活度。
例如图5所示，第一部分预设比特位和第二部分预设比特位可以分别包括1个预设比特位，其中，第1组预设比特位中的第一部分预设比特位值为1，可以表示接收数据帧所在的目标频段为第2个频段，并且第1组预设比特位中的第二部分预设比特位值为0，可以表示在目标频段(第2个频段)接收数据帧的接收状态为失败，相应地，第2组预设比特位中的第一部分预设比特位值为0，可以表示接收数据帧所在的目标频段为第1个频段，并且第2组预设比特位中的第二部分预设比特位值为1， 可以表示在目标频段(第1个频段)接收数据帧的接收状态为成功。
可选地，所述数据帧包括k段子数据帧，所述接收端分k次发送所述k段子数据帧；
其中，所述第一部分预设比特位包括p个预设比特位，所述第二部分预设比特位包括k个预设比特位，k＞1，p≥1。
图6是根据本公开的实施例示出的又一种反馈信息帧的示意图。
在一个实施例中，传输端可以将在每个频段下发送的数据帧都划分为k段子数据帧，然后在每个频段都分k次向接收端发送k段子数据帧，而在每个频段发送子数据帧的动作是同时的。
在这种情况下，接收端生成的反馈信息帧中，第一部分预设比特位包括p个预设比特位，第二部分预设比特位包括k个预设比特位，也即通过p个预设比特位指示接收数据帧所在的目标频段信息，通过k个预设比特位指示在目标频段接收数据帧的接收状态。
例如图6所示，第一部分预设比特位包括1个预设比特位，第二部分预设比特位包括2个预设比特位，其中，第1组预设比特位中的第一部分预设比特位值为1，可以表示接收数据帧所在的目标频段为第2个频段，并且第1组预设比特位的第二部分预设比特位中的第1个预设比特位值为0，可以表示在目标频段(第2个频段)接收第一个子数据帧的接收状态为失败，相应地，第2组预设比特位中的第一部分预设比特位值为0，可以表示接收数据帧所在的目标频段为第1个频段，并且第2组预设比特位的第二部分预设比特位中的第2个预设比特位值为1，可以表示在目标频段(第1个频段)接收低2个子数据帧的接收状态为成功。
图7是根据本公开的实施例示出的另一种接收状态反馈方法的示意流程图。如图7所示，所述接收传输端在n个频段同时发送的数据帧包括：
在步骤S11中，接收m个传输端在n个频段同时发送的数据帧，m＞1；
其中，不同的所述传输端在不同的所述频段发送数据帧；所述反馈信息帧还包括接收地址字段，所述接收地址字段为与所述m个传输端的地址相关联的组播地址。
在一个实施例中，传输端在n个频段同时向接收端发送数据，可以是指m个传输端在n个频段同时向接收端发送数据帧，其中，m＞1，具体地，可以是m＝n，或者 m＞n，或者m＜n，并且不同的传输端在不同的频段发送数据帧，据此，可以避免不同的传输端在同一个频段同时发送数据帧，而导致接收端不能正确解码在该频段接收的数据帧。
在这种情况下，接收端向传输端发送反馈信息帧，就需要在反馈信息帧中记载m个传输端的信息，具体可以记载组播地址比特位，而组播地址比特位与m个传输端是相关的，例如可以对m个传输端的地址进行编码得到组播地址比特位，然后将组播地址比特位记载在RA字段中，最后将反馈信息帧发送给m个传输端中的每个传输端。
传输端在接收到反馈信息帧后，通过解析RA字段中的组播地址比特位，可以确定出该反馈信息帧是否是发给自己的，若不是，则可以忽略该反馈信息帧，若是，则可以根据该反馈信息帧中的n组预设比特位确定接收端在n个频段接收数据帧的接收状态。
需要说明的是，当仅有一个传输端在n个频段同时发送数据帧时，接收端生成的反馈信息帧中也可以包括接收地址字段，所述接收地址字段与在n个频段同时发送数据帧的传输端的地址相关联。
可选地，所述接收端和所述传输端中一个为无线接入点，另一个为站点。
在一个实施例中，在无线接入点向站点发送数据帧时，无线接入点作为传输端，站点作为接收端，而在站点向无线接入点发送数据帧时，站点作为传输端，无线接入点作为接收端。
可选地，所述n个频段包括以下至少之一：
2.4GHz频段，5.8GHz频段，6-7GHz频段。
需要说明的是，所述n个频段并不限于上述3个频段，可以根据需要进行设置。
与前述的接收状态反馈方法的实施例相对应，本公开还提供了接收状态反馈装置的实施例。
图8是根据本公开的实施例示出的一种接收状态反馈装置的示意框图。本公开实施例所示的接收状态反馈方法，可以适用于Wi-Fi网络中的接收端，其中，所述接收端可以是无线接入点，例如路由器，所述接收端也可以是站点，例如手机，平板电脑，可穿戴设备等电子设备。

接收模块1，被配置为接收传输端在n个频段同时发送的数据帧，其中，n＞1；

发送模块3，被配置为向所述传输端发送所述反馈信息帧。
可选地，每组预设比特位包括一个预设比特位，n个所述预设比特位中第i个预设比特位用于指示在所述n个频段中第i个频段接收数据帧的接收状态，1≤i≤n。
可选地，所述数据帧包括k段子数据帧，所述接收端分k次发送所述k段子数据帧；
其中，每组预设比特位包括k个预设比特位，在所述n组预设比特位中的第i组预设比特位中，所述k个预设比特位用于指示在所述n个频段中第i个频段接收所述k段子数据帧的接收状态，k＞1，1≤i≤n。
