具体地，本发明实施例中的数据接收端可以为接入点AP，多用户数据发送端可以为站点STAs，那么，该数据可以为多用户数据发送端STAs向AP同时上行发送的数据；而且该用户数据发送端可以同时发送多个数据帧，可以所有用户数据发送端都同时发送多个数据帧；本发明各实施例但不限于AP和STAs，可以适用于其它所有点对多点通信(Peer to Multi-Peer，P2MP)的双方设备。
步骤S202：根据所述数据的接收状态生成组块确认消息帧，所述组块确认消息帧包含组信息标识以及数据接收状态信息，所述组信息标识用于指示所述组块确认消息帧对应预设的同属一组的多用户数据发送端，所述数据接收状态信息用于指示对所述同属一组的各个用户数据发送端的数据接收状态，包括对所述至少一个用户数据发送端同时发送的多个数据帧的接收状态；
具体地，一个组块确认消息帧对应同属一组的多用户数据发送端，通过该组块确认消息帧中的组信息标识来指示该组块确认消息帧对应的同属一组的多用户数据发送端，说明该组消息确认帧中的确认数据是为了发送给对应的同属一组的多用户数据发送端，该确认数据可以通过组块确认消息帧中 的数据接收状态信息来说明，指示该同属一组的各个用户数据发送端的数据接收状态，例如指示哪个多用户数据发送端的数据接收失败，哪个多用户数据发送端的数据接收成功等，并且针对某用户数据发送端同时发送多个数据帧的情况，该数据接收状态还包括对该用户数据发送端同时发送的多个数据帧的接收状态。
步骤S204：向所述多用户数据发送端发送所述组块确认消息帧。
具体地，数据接收端将生成的组块确认消息帧广播发送给多用户数据发送端后，该组块确认消息帧对应的多用户数据发送端将解析该组块确认消息帧，获知自身发送的数据是否被正确接收。
进一步地，如图3示出的本发明提供的另一实施例的数据传输方法的流程示意图，该方法包括：
步骤S300：将所述多用户数据发送端进行分组；
具体地，本发明实施例中数据接收端在根据数据的接收状态生成组块确认消息帧之前，还可以与多用户数据发送端进行协商，根据实际的通信环境将多用户数据发送端进行分组；例如数据接收端为AP，多用户数据发送端为STAs时，AP可以根据各个STAs运行时的干扰值进行分组，比如将相互干扰值较低的分为一组，将相互干扰值较高的分为另一组，等等。
步骤S302：针对每组多用户数据发送端生成各自对应的组信息标识和组内位置信息；
具体地，该组信息标识是用于指示该组中的各个用户数据发送端所属的组，本发明各个实施例中的组信息标识可以为组播地址信息、组号信息或广播地址信息，或者上述信息的任意组合，等等；该组内位置信息用于指示该组中的各个用户数据发送端所在的组内位置，比如AP将4个STAs分为同一组，那么还为该4个STAs分配组内位置信息，以指示哪些个STAs为第一个、第二个、第三个和第四个STAs。
步骤S304：向所述多用户数据发送端对应分配所述组信息标识和组内位置信息；或向所述多用户数据发送端对应分配所述组信息标识和关联标识；
具体地，该多用户数据发送端接收到被分配的组信息标识可获知自身所属的组；接收到的组内位置信息或者关联标识，可以获知自身在所属组中的 组内位置。
步骤S306：同时接收多用户数据发送端同时发送的数据；
步骤S308：根据所述数据的接收状态生成组块确认消息帧；
步骤S310：向所述多用户数据发送端发送所述组块确认消息帧。
具体地，步骤S306至S310可以参考上述图2实施例中的步骤S200至S204；当该多用户数据发送端接收到自身对应的组块确认消息帧后，将解析该组块确认消息帧，然后根据自身对应的组内位置，获知自身发送的数据是否被正确接收，并且在知道自身发送的数据没有被正确接收后，重新向数据接收端发送该数据。
再进一步地，本发明实施例中的数据接收状态信息用于指示对所述同属一组的各个用户数据发送端的数据接收状态，具体可以包括：当所述同属一组的多用户数据发送端的数据被正确接收，则在所述数据接收状态信息中对应设置第一预设值；当所述同属一组的多用户数据发送端的数据未被正确接收，则在所述数据接收状态信息中对应设置第二预设值。该第一预设值可以为“1”，该第二预设值可以为“0”；或者反过来，该第一预设值为“0”，该第二预设值为“1”，只要通信双方协商规定好即可。
再进一步地，本发明实施例中的组块确认消息帧还可以包括所述组内位置信息或关联标识，该组块确认消息帧中的组内位置信息或关联标识用于指示该同属一组的各个用户数据发送端识别出各自对应的数据接收状态信息；该数据接收状态信息通过位图信息Bitmap的方式来设置；该位图信息与本发明实施例中的组内位置信息相对应，以指示所述同属一组的各个用户数据发送端的数据接收状态。下面结合2种本发明实施例提供的组块确认消息帧格式的结构，来进行举例说明：
1、如图4所示的本发明提供的组块确认消息帧格式的结构示意图，该组块确认消息帧可以包括：帧控制、时长/标识、组信息标识、发送源地址、组内位置信息、位图信息以及帧校验序列；
具体地，该组信息标识可供用户数据发送端(如站点设备)寻址使用；该组块确认消息帧中的组内位置信息用于指示该同属一组的各个用户数据发送端识别出各自对应的数据接收状态信息；该组内位置信息可以与该位图 信息结合在一起，比如组内位置信息为“00000110”，那么指示该组中位置为6的用户数据发送端；若位图信息为“1111111100111111”，那么指示该位置为6的用户数据发送端同时发送的16个数据帧中，第8和第7个数据帧没有被数据接收端正确接收；若位图信息为“1”，则表明该用户数据发送端发送了1个数据帧，并且被数据接收端正确接收。那么该组的各个设备接收并解析该组块确认消息帧后，将获知自身发送的数据是否被正确接收，并且该用户数据发送端将向数据接收端重新发送第8和第7个数据帧；
可理解的是，当多用户数据发送端解析组块确认消息帧中的组信息标识，发现该组信息标识与被分配的组号信息相一致时，则进一步解析该组块确认消息帧中的源地址，否则不接受该组块确认消息帧，抛弃该组块确认消息帧。该组中有多少个用户数据发送端，那么图4在发送源地址与帧校验序列之间就包括多少个组内位置信息和位图信息，即每个组内位置信息和位图信息可对应一个用户数据发送端。
2、如图5所示的本发明提供的另一实施例的组块确认消息帧格式的结构示意图，该组块确认消息帧可以包括：帧控制、时长/标识、组信息标识、发送源地址、关联标识(AID)、位图信息以及帧校验序列；
具体地，该关联标识用于指示该同属一组的各个用户数据发送端识别出各自对应的数据接收状态信息；该关联标识可以与该位图信息结合在一起，比如关联标识为“0000000000000011”，那么指示该组中关联标识的值为3的用户数据发送端；若位图信息为“1111111100111111”，那么指示关联标识值为3的用户数据发送端同时发送的16个数据帧中，第8和第7个数据帧没有被数据接收端正确接收；若位图信息为“0”，则表明该用户数据发送端发送了1个数据帧，并且没有被数据接收端正确接收。那么该组的各个设备接收并解析该组块确认消息帧后，将获知自身发送的数据是否被正确接收，并且该用户数据发送端将向数据接收端重新发送第8和第7个数据帧；
可理解的是，当多用户数据发送端解析组块确认消息帧中的组播地址信息，发现该组播地址信息与被分配的组播地址信息相一致时，则进一步解析该组块确认消息帧中的源地址，否则不接受该组块确认消息帧，抛弃该组块确认消息帧。该组中有多少个用户数据发送端，那么图5在发送源地址与帧校验序列之间就包括多少个关联标识和位图信息，即每个关联标识和位图信 息可对应一个用户数据发送端。
需要说明的是，本发明各个实施例中的组信息标识可以为如下任意一项：
以组信息标识为组号信息为例进行说明，比如该组号信息为“00000011”，那么指示为该组为第3组；
以组信息标识为组播地址信息为例进行说明，比如该组播地址信息可以为6个字节的地址信息，类似于MAC地址，来表示所属的组；
以组信息标识为组号信息和组播地址信息为例进行说明，即，也可以将组号信息与组播地址信息这两个域进行结合，生成一个新的信息，以指示组块确认消息帧对应同属一组的多用户数据发送端，本发明不进行限定。同样地，上述实施例中的组信息标识也可以为广播地址信息，或该广播地址信息与组号信息或组播地址信息的任意组合，这里不再赘述。
需要说明的是，图4或图5中，位图信息不限于1个字节或2个字节，可以根据具体实际情况由数据接收端进行动态设置，比如当数据接收端为接入点设备，用户数据发送端为站点设备时，接入点设备给站点设备分配的传输机会(Transmission Opportunity，TXOP)是一定的，与每个站点设备的调试与编码(Modulation and Coding Scheme，MCS)方式也是一定的，那么就能够算出站点设备所连续发送数据帧的个数，从而设置位图信息的比特位。
需要说明的是，本发明实施例的无线通信方法无需考虑兼容的问题，因为老的站点STA能够通过ACK的物理头部分解析到整个帧的时长，所以符合现有的随机退避机制；对于新的ACK帧格式，可以通过MAC帧头的Frame control域的Type以及Subtype子域来进行定义封装，其具体表示如下：

下面相应地，结合图6示出的本发明提供的另一实施例的数据传输方法的流程示意图，从多用户数据发送端来描述本发明的技术方案，该方法包括：

步骤S604：当解析所述组块确认消息帧中的组信息标识，确认接收所述组块确认消息帧后，解析所述组块确认消息帧中的数据接收状态信息，获取本端对应的数据接收状态。
具体地，获取本端对应的数据接收状态之后，还包括：根据本端对应的数据接收状态，对未被正确接收的数据进行重新发送。
进一步地，本发明实施例中在步骤S702之前，还可以包括接收所述数据接收端分配的组信息标识和组内位置信息或接收所述数据接收端分配的组信息标识和关联标识；在步骤S702接收所述数据接收端反馈的组块确认消息帧之后，步骤S704解析所述组块确认消息帧中的数据接收状态信息之前，还可以包括：解析所述组块确认消息帧中的组信息标识，当解析的组信息标识与所述分配的组信息标识相同时，则确认接收所述组块确认消息帧。
再进一步地，本发明实施例中的组块确认消息帧还可以包括该组内位置信息，在确认接收该组块确认消息帧之后，解析该组块确认消息帧中的数据接收状态信息，获取本端对应的数据接收状态之前，还包括：
根据所述数据接收端分配的组内位置信息，解析所述组块确认消息帧中的组内位置信息，获取本端对应的数据接收状态信息；
并且，数据接收状态信息可以通过位图信息的方式来设置；该位图信息用于指示该同属一组的各个用户数据发送端的多个数据帧的接收状态，该解析该组块确认消息帧中的数据接收状态信息，获取本端对应的数据接收状态包括：从获取的本端对应的数据接收状态信息中解析本端对应的位图信息，获取本端同时发送多个数据帧对应的数据接收状态。
具体地，参考图4，假设A用户数据发送端接收到数据接收端分配的组内位置信息为“00000110”，即表明组内位置为6，那么A用户数据发送端确认接收组块确认消息帧后，将解析该组块确认消息帧中的组内位置信息，找到“00000110”的组内位置信息对应的数据接收状态信息，比如为“1111111100111111”的位图信息，那么可获知同时发送的16个数据帧中，第8和第7个数据帧没有被数据接收端正确接收，需要重新这两个数据帧。
再进一步地，本发明实施例中的组块确认消息帧还可以包括关联标识，该确认接收该组块确认消息帧之后，解析该组块确认消息帧中的数据接收状态信息，获取本端对应的数据接收状态之前，还包括：根据该数据接收端分配的关联标识，解析该组块确认消息帧中的关联标识，获取本端对应的数据接收状态信息；
并且，该数据接收状态信息通过位图信息的方式来设置；该位图信息用于指示该同属一组的各个用户数据发送端的多个数据帧的接收状态，该解析该组块确认消息帧中的数据接收状态信息，获取本端对应的数据接收状态包括：从获取的本端对应的数据接收状态信息中解析本端对应的位图信息，获取本端同时发送多个数据帧对应的数据接收状态。
具体地，参考图5，假设B用户数据发送端接收到数据接收端分配的关联标识为“0000000000000011”，即表明关联标识的值为3，那么B用户数据发送端确认接收组块确认消息帧后，将解析该组块确认消息帧中的关联标识，找到“0000000000000011”的关联标识对应的数据接收状态信息，比如为“1111111100111111”的位图信息，那么可获知同时发送的16个数据帧中，第8和第7个数据帧没有被数据接收端正确接收，需要重新这两个数据帧。
具体地，多用户数据发送端侧的实现过程，具体可以对应参考上述图1至图5实施例的描述，这里不再赘述。
通过实施本发明实施例，预先将站点设备进行分组，根据数据的接收状态生成组块确认消息帧，以指示对每组站点设备各自发送数据的接收状态，减少了双方进行数据通信时发送的ACK帧数量，解决了现有技术中通过有序的回复ACK帧给用户设备而造成的不利于频谱的有效利用，以及不利于用户设备的省电的技术问题，大大提高了频谱的有效利用率，同时利于用户设备省电。
