随着正交频分多址(Orthogonal Frequency Division Multiple Access，简称OFDMA)技术的发展，目前的无线通信系统已经能够支持多个站点(Station，简称STA)同时进行数据传输。当多个STA通过OFDMA技术向接入点(Access Point，简称AP)发送信息时，该信息可以为控制帧，管理帧，也可为普通数据帧。AP可以以多用户-块确认(Multi-Block Acknowledgement，简称M-BA)帧结构的形式向多个站点广播确认，图1为现有技术中提供的M-BA帧结构示意图，如图1所示，其中，M-BA帧包括：至少一个块确认/确认信息，现有技术中每一个块确认/确认信息是给一个STA发送确认的，通常如果AP只是向一个STA发送的单个媒体接入控制层协议数据单元(medium access control protocol data unit，简称MPDU)进行确认，那么块确认/确认信息则是确认信息，如果AP只是向一个STA发送的聚合媒体接入控制层协议数据单元(aggregate medium access control protocol data unit，简称A-MPDU)进行确认，那么块确认/确认信息则是块确认信息。每个块确认/确认信息中都包括有一个关联标识(Association Identifier，简称AID)，每个AID是AP向STA分配的唯一标识，该标识用于标识STA。它表示该确认信息是AP发送给AID所标识的STA，其中，AP是在与STA建立关联时，向STA分配AID的。
现有技术中，AP与多个STA通过OFDMA建立关联过程为：首先，AP广播下行触发帧(Downlink Trigger)，该下行触发帧通过资源分配指示比特 来指示哪些子信道用于多个STA发送关联请求消息，其次，多个STA通过一定的随机退避算法竞争可以使用的子信道，并向AP发送关联请求消息，AP若予以M-BA形式向多个STA发送关联确认消息时，存在下面的问题：由于AP与多个STA之间还没有建立关联，那么这时AP并不知道每个STA的AID。
因此，AP通过M-BA形式是无法向多个STA发送关联确认消息的，从而无法建立AP与STA之间的关联，进而降低通信可靠性。

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
本发明实施例基于无线局域网络(Wireless Local Area Networks,简称WLAN)技术，本发明实施例的应用场景为：AP与STA在进行通信之前，AP需要与STA之间建立关联，而建立关联的重要环节则是STA要获得AP为它分配的AID，该AID用于唯一标识STA。通常情况下，AP会接收多个STA发送的关联请求消息，这多个STA发送关联请求消息是可以基于OFDMA技术，AP向多个STA发送关联确认消息的方式可以分为两种：一、OFDMA确认，即在各个正交子信道上向多个站点发送确认ACK或者块确认BA，其中ACK是针对单个媒体访问控制协议数据单元(Media Access Control Protocol Data Unit，简称MPDU)进行确认的，而BA是针对聚合-媒体访问控制协议数据单元(Aggregate-Media Access Control Protocol Data Unit，简称A-MPDU)进行确认的。二、M-BA帧确认，它是一种广播消息，即AP通过M-BA帧将对多个STA发送的确认，广播发送给各个STA。如图1所示，M-BA帧包括：控制帧(Control frame)，时长/标识(duration/ID)，接收地址(Receive Address，简称RA)，发送地址(Transmit Address，简称TA)，块确认控制(BA Control)，块确认/确认信息(Block Acknowledgement/Acknowledgement Information，简称BA/ACK Info)和帧校验序列(Frame Check Sequence，简称FCS)。其中，块确认控制包括块确认/确认策略(BA/ACK policy)，多个-通信标识符(Multi-Traffic Identifier，简称Multi-TID)，压缩位图(compress bitmap)，组播重传(Groupcast with retries，简称GCR)，保留(Reserved)字段和通信标识符_信息(Traffic Identifier_Information，简称TID_info)，其中TID info用来指示存在多少个BA/ACK Info；进一步地，BA/ACK Info包括：每个通信标识符信息(Per Traffic Identifier Information，简称Per TID Info)，当BA/ACK Info为BA Info时，则BA/ACK Info还包括块确认起始序列控制(Block Acknowledgement Starting Sequence Control)和块确认位图(Block Acknowledgement bitmap)。更进一步的，在Per TID Info的前11比特设置有STA的AID，用来指示AP要将确认发送给哪个站点。第12比特为块确认/确认指示(BA/ACK Indication)，第13～16比特为通信标识 符TID。下面具体介绍AP与STA之间的关联建立方法：
图2为本发明一实施例提供的关联的建立方法的流程图，该方法的执行主体为AP，如图2所示，该方法具体包括如下流程：
S201：接入点AP广播触发帧，触发帧用于指示至少一个可使用的子信道，并触发多个第一站点STA同时进行上行数据传输；
具体的，这里的第一STA为与AP还未建立关联的STA，通常AP广播的触发帧可以通过资源分配指示比特指示哪些STA在哪些可使用的子信道上传输数据，也可以通过资源分配指示比特指示哪些可使用的子信道用于多个第一STA随机竞争使用，以便多个第一STA通过一定的随机避退算法竞争可使用的子信道。由于AP和第一STA之间还没有建立关联，因此，这里的触发帧只能是后者，即它通过资源指示比特指示至少一个可使用的子信道用于多个STA随机竞争使用，这里多个第一STA同时传输上行数据的方式可以为OFDMA方式。
S202：AP接收多个第一STA中的每个第一STA在对应的可使用的子信道上发送的关联请求消息，关联请求消息包括第一STA的媒体访问控制(Media Access Control，简称MAC)地址；
具体地，当AP发送触发帧，并触发帧中资源指示比特中指示哪些子信道可用来多个第一STA竞争子信道，接收到该触发帧的第一STA通过可使用的子信道发送关联请求消息，比如：STA1和STA2在子信道8上发送，当然，关联请求消息中会携带第一STA的MAC地址。
S203：AP广播多用户-块确认M-BA帧，M-BA帧包括至少一个关联确认信息，关联确认信息为关于关联请求消息的确认信息；其中，若触发帧包括AP分配给每个可使用的子信道的临时标识，则关联确认信息包括至少一个第二STA的MAC地址，以使每个第二STA确定关联确认信息为AP发送给自己的确认信息，并将对应的可使用的子信道的临时标识作为自己的第一AID，第二STA为所述AP成功接收到的所述关联请求消息对应的第一STA，否则，关联确认信息包括至少一个第二STA的MAC地址和AP分配给第二STA的第一AID；
具体地，这里的关联确认信息对应于图1中的块确认/确认信息，不过，本发明实施例中的块确认信息与现有技术有所不同，本发明实施例中的块确 认信息指的是一条关联确认信息可以同时给多个第一STA进行确认，也可以给一个第一STA进行确认，进一步地，AP接收同一子信道上发送的关联请求消息时，通常成功接收信噪比最高的信号，比如：STA1和STA2都在子信道8上发送关联请求消息，但是STA1发送的消息的信噪比要高于STA2，这时AP通过只能接收到STA1的消息。根据触发帧所包括的内容不同，可以分为以下两种情况：
一、若触发帧包括AP分配给每个可使用的竞争子信道的临时标识，那么对于接收到触发帧的第一STA来讲，它便获知了可使用的竞争子信道的临时标识，这种情况下，当该第一STA竞争到子信道后，则获得子信道的临时标识，并默认该临时标识为自己的第一AID，这种情况下，关联确认信息可以只包括至少一个第二STA的MAC地址，那么当某个第一STA接收到M-BA帧后，如果在某个关联确认信息BA/ACK Info中读取到了自己的MAC地址，则说明该关联确认信息BA/ACK Info是对自己发送的关联请求消息进行确认的，这时这个第一STA即为第二STA，它将当初发送关联请求消息使用的竞争子信道的临时标识作为自己的第一关联标识AID，该实施例中的第二STA为AP成功接收到的关联请求消息对应的第一STA。
可选地，该M-BA帧中还包括：第二STA对应的所述可使用的子信道的临时标识。即，即使AP当初在触发帧中已经广播过每个可使用的子信道的临时标识，但是它为了确保期间，会再在M-BA帧中携带第二STA对应的所述可使用的子信道的临时标识。
二、若触发帧中没有包括AP分配给每个可使用的子信道的临时标识，则关联确认信息包括至少一个第二STA的MAC地址和AP分配给第二STA的第一AID。这种情况下，当某个第一STA读取到M-BA帧中某个关联确认信息包括有自己的MAC地址，则说明该关联确认信息是对自己发送的关联请求消息进行确认的，它会获取包含自己MAC地址的关联确认信息所包括的第一AID。
值得说明的是，本发明实施例中的第一AID相当于AP分配给第二STA的一个临时标识。
S204：AP根据第一AID向对应的第二STA发送关联响应消息，其中，关联响应消息用于指示第二STA与AP之间关联建立成功，关联响应消息包 括：第二AID，所述第二AID用于标识所述第二STA，所述第二AID与所述第一AID相同或者不同。
具体地，在步骤S203中，AP广播的M-BA帧只是一个包括关联确认信息的帧，但是，AP除了需要向第二STA发送AID外，它还需要将其他的信息，比如：增强的分布式信道访问(Enhanced Distributed Channel Access，简称EDCA)参数，20/40基本服务集(Basic Service Set，简称BSS)BSS共存等，当然，由于在发送完M-BA帧之后，有可能会出现当前AP取消了一些关联STA，当取消之后，该STA的AID就可以撤销，AP为了便于管理，比如：希望分配给各个STA的AID可以是连续的，基于这种情况，AP可能会对当初分给第二STA的第一AID进行调整，即重新分配给第二STA一个第二AID，因此上述的第一AID称为AP分配给第二STA的临时标识。当然，这里的第二AID也有可能是与第一AID是相同的。
本发明实施例提供一种关联的建立方法，包括：接入点AP广播触发帧，AP接收至少一个多个第一站点STA中的每个第一STA在对应的可使用的子信道上发送的关联请求消息，AP广播多用户-块确认M-BA帧，M-BA帧包括至少一个关联确认信息，关联确认信息为关于关联请求消息的确认信息；其中，若触发帧包括AP分配给每个可使用的竞争子信道的临时标识，则关联确认信息包括至少一个第二STA的MAC地址，以使每个第二STA将对应的可使用的竞争子信道的临时标识作为自己的第一关联标识AID，否则，关联确认信息包括至少一个第二STA的MAC地址和AP分配给第二STA的第一AID，AP通过下行OFDMA方式向发送给第二STA发送关联响应消息，并通过下行OFDMA的资源指示比特指示与第一AID相对应的STA在某个子信道接收关联响应。这里的某个子信道是当前任一个可使用的子信道，通常AP会选择较优的子信道向该STA发送关联响应消息，其中，关联响应消息用于指示第二STA与AP之间关联建立成功。由于AP在M-BA帧中某个关联确认信息包括有第二STA的MAC地址，因此，只要第二STA读取到了自己的MAC地址，则说明该关联确认信息是对自己发送的关联请求进行确认的，进而实现AP与STA之间的关联，保证了通信的可靠性。
由于通常一个M-BA帧中可以包括至少一个关联确认信息，也可以包括普通确认信息，该普通确认信息不是针对关联请求消息的确认信息，那么如 何区别M-BA帧中的确认信息是关联确认信息还是普通确认信息，下面进行具体介绍：
一种可选方式，若触发帧包括AP分配给每个可使用的子信道的临时标识，则所述关联确认信息还包括：所述第二STA对应的所述可使用的子信道的临时标识，临时标识还用于表示所述关联确认信息为关于所述关联请求消息的确认信息。下面所有的附图中的块确认/确认信息即为本发明实施例的关联确认信息，图3A为本发明一实施例提供的M-BA帧结构示意图一，如图3A所示，在块确认/确认信息中的每个通信标识符信息中包括有临时标识，具体地，由于通常情况下，AP广播的M-BA帧中的块确认/确认信息BA/ACK Info不一定是关联确认信息，可能会是普通确认信息，那么对于第一STA来讲，在接收到触发帧时，它就知道可使用的子信道的临时标识，并将该临时标识作为自己的第一AID，因此，在接收到M-BA帧时，它只要识别出在某个块确认/确认信息中存在这个临时标识，它就可以确定该块确认/确认信息是关联确认信息。进一步地，如图3A所示，该块确认/确认信息还包括MAC地址，那么第一STA还可以通过MAC地址进一步确定块确认/确认信息是否是发送给自己的。图3B为本发明一实施例提供的M-BA帧结构示意图二，图3B中的每个通信标识符信息中包括有4比特的MAC地址，当第一STA接收到触发帧时，它就知道可使用的子信道的临时标识，并将该临时标识作为自己的第一AID，因此，在接收到M-BA帧时，它只要识别出在某个块确认/确认信息中存在这个临时标识，它就可以确定该块确认/确认信息是关联确认信息，进一步地，并且根据临时标识可以确定该块确认/确认信息是AP发送给它的，更进一步地，可以通过4比特的MAC地址与自己的MAC地址的比对，确定该块确认/确认信息是AP发送给它的。
另一种可选方式，所述M-BA帧关联确认信息还包括：哑关联标识符，所述哑关联标识符用于表示所述关联确认信息为关于所述关联请求消息的确认信息。其中，哑关联标识符可以用11比特个0来表示，也可以是AP指定的某个特殊的标识符。具体地，图4为本发明一实施例提供的M-BA帧结构示意图三，如图4所示，该哑关联标识符位于每个通信标识符信息中，占用11比特位，它可以使用特殊的AID来表示，比如：用11比特个0来表示，当第一STA接收到触发帧M-BA帧，当第一STA确定某个块确认/确认信息 存在该哑关联标识符时，则第一STA确定该块确认/确认信息为关联确认信息，进一步地，如图4所示，M-BA中的MAC地址位于每个通信标识符信息之后，占用6个字节，对于M-BA帧存在的两种情况，临时标识或者第一AID可以位于MAC地址之后，占用2个字节。
上述所述M-BA对关联请求确认的方法还可以拓展到除对普通数据帧确认以外的确认，比如对探测(sounding)的波束成型矩阵反馈帧的确认，对认证请求的确认。此时，每个通信标示符字段里的前11比特哑关联标识符用于表示所述确认信息为关于所述除对普通数据帧确认以外的确认信息。每个通信标识符字段里后面5比特可以重新定义，可以用来指示该确认信息是对哪类帧进行确认和每个通信标识符字段后面紧跟的长度，这里的长度可以以1字节单位，也可以2字节单位。比如，用5比特中的2比特指示4种确认信息的类型，用5比特中的3比特指示每个通信标识符字段后面紧跟的长度。对于对探测(sounding)的波束成型矩阵反馈帧的确认，每个通信标识符字段后面紧跟2字节的段确认位图(Segment ACK Bitmap)。
再一种可选方式，所述关联确认信息中的特殊通信标识符TID还用于所述关联确认信息为关于所述关联请求消息的确认信息。图5为本发明一实施例提供的M-BA帧结构示意图四，如图5所示，通常在每个通信标识符信息中的第13-16比特位处填写的是TID，然而，基于增强的分布式信道访问(Enhanced Distributed Channel Access，简称EDCA)技术，M-BA帧中的TID通常为8种，而这8种只需要占用3比特就可以了，然而，每个通信标识符信息中的TID分配了4个比特位，因此，值为0-7的TID可以指示正常的TID，值为8-15的TID即为特殊的TID，因此，可以通过特殊的TID来表示块确认/确认信息为关于关联请求消息的确认信息。进一步地，M-BA中的MAC地址位于每个通信标识符信息之后，占用6个字节，而当触发帧中包括AP分配给每个可使用的子信道的临时标识，因此在MAC地址之后可以没有临时标识。
再一种可选方式，所述关联确认信息中的通信标识符TID中的1比特还用于指示所述关联确认信息为关于所述关联请求消息的确认信息。图23为本发明一实施例提供的M-BA帧结构示意图八，如图23所示，通常在每个通信标识符信息中的第13-16比特位处填写的是TID，然而，基于增强的分布式 信道访问(Enhanced Distributed Channel Access，简称EDCA)技术，M-BA帧中的TID通常为8种，而指示这8种TID只需要占用3比特。然而，每个通信标识符信息中的TID分配了4个比特位，因此，TID中的3个比特可以仍作为指示对应要确认的MAC帧的TID。因此，可以通过TID里另外一个比特来表示所述块确认/确认信息为关于关联请求消息的确认信息，该一个比特为图23中的关联确认指示比特。较优的实施方式，该比特为TID的最后一个比特，可理解的是，该比特可以位于所述每个通信标识符信息中第13-16比特中的任意一个比特。
具体地，所述关联确认指示比特的取值具体如下：比如将该比特置1，表示块确认/确认信息为关于关联请求消息的确认信息，否则，表示块确认/确认信息不是关于关联请求消息的确认信息。进一步地，M-BA中的MAC地址位于每个通信标识符信息之后，占用6个字节。此时，每个通信标识符字段里的AID子字段里填写的是AP给成功发送关联请求的站点分配的第一AID。需要说明的是，第一AID的名称可以为Pre-AID或其他类似的名称。
进一步地，由于一个M-BA帧中某个BA/ACK Info可能包括有对多个未关联STA发送的关联请求的确认，即M-BA帧中包括有一个BA/ACK Info，该BA/ACK Info中包括对多个未关联STA发送的关联请求消息的确认，图6为本发明一实施例提供的M-BA帧结构示意图五，如图6所示，该M-BA帧中包括一个BA/ACK Info，该BA/ACK Info中包括有多个MAC地址和与该MAC地址对应的临时标识或者第一AID，那么如何确定AP通过同一条关联确认信息向多少个STA进行确认，下面进行具体介绍可以通过以下方式确认：
一、所述关联确认信息中的特殊通信标识符TID或TID的全部4比特表示所述AP通过同一条所述关联确认信息向多少个第二STA进行确认。这种方法不适用于特殊TID用于表示关联确认信息为关于所述关联请求消息的确认信息的情况，除此之外，均可以使用这种方式来表示。比如：TID值为8，则对应该条关联确认信息向1个STA发送确认，TID值为9，则对应该条关联确认信息向2个STA发送确认等。可选的，TID的全部4比特用来指示该条关联确认信息向多少个STA发送确认。
另一种实施方式是，特殊通信标识符TID的范围或TID的全部4比特也可以用来指示该关联请求确认信息里每个通信标识符信息后面紧跟多少个字 节信息，比如以2字节为单位。
二、M-BA帧还包括：统计标识符，所述统计标识符表示所述AP通过同一条所述关联确认信息向多少个第二STA进行确认。一方面，该统计标识符可以位于每个通信标识符信息之后，AP可以为该统计标识符固定分配几个比特位。另一方法，块确认起始序列位于每个通信标识符信息之后，所述统计标识符占用所述M-BA帧中的块确认起始序列控制中所保留的比特位。图7为本发明一实施例提供块确认起始序列控制字段的示意图，如图7所示，该块确认起始序列控制包括4个保留比特位和起始序列号，因此，当起始序列号为特殊的起始序列号，比如全0,那么可以利用保留的比特位来填写统计标识符。值得说明的是，该统计标识符还可以位于M-BA帧的其他位置，本发明对此不做限制。
需要说明的是，本发明实施例中，每个通信标识符信息之后，若跟MAC地址，或者还包括临时标识/第一AID，或者是多个MAC地址，多个临时标识/第一AID。此时需要通过填0来保证上述内容所需的比特数是8的倍数，即以1字节为单位，或者也可以以10字节为单位。
图8为本发明另一实施例提供的一种关联的建立方法的流程图，该方法的执行主体为第一STA，其中该方法具体包括如下流程：
S801：第一站点STA接收接入点AP广播的触发帧，所述触发帧用于指示至少一个可使用的子信道，并触发多个第一站点STA同时进行上行数据传输；
具体地，这里的第一STA为未与AP建立关联的STA，通常AP广播的触发帧可以通过资源分配指示比特指示哪些STA在哪些可使用的信道上传输数据，也可以通过资源分配指示比特指示哪些可使用的信道用于多个第一STA随机竞争使用，以便第一STA通过一定的随机避退算法竞争可使用的信道。由于AP和第一STA之间还没有建立关联，因此，这里的触发帧只能是后者，即它用于指示至少一个可使用的信道。
S802：第一STA在对应的可使用的信道上发送关联请求消息，关联请求消息包括第一STA的媒体访问控制MAC地址；
S803：第一STA接收AP广播的多用户-块确认M-BA帧，所述M-BA帧包括至少一个关联确认信息，所述关联确认信息为关于所述关联请求消息 的确认信息；
S804：若触发帧包括AP分配给每个可使用的子信道的临时标识，则M-BA帧包括至少一个第二STA的MAC地址；若第一STA查找第一STA的MAC地址在M-BA帧中，则第一STA确定关联确认信息为AP发送给自己的确认信息，并将对应的可使用的子信道的临时标识作为自己的第一AID；若触发帧没有包括AP分配给每个可使用的子信道的临时标识，则M-BA帧包括至少一个第二STA的MAC地址和AP分配给第二STA的第一AID，若第一STA查找第一STA的MAC地址在M-BA帧中，则第一STA获取第一STA的MAC地址所对应的第一AID，第二STA为AP成功接收到的关联请求消息对应的STA；
具体地，对于第一STA来讲，当它确定M-BA帧为关联请求消息之后，则会在M-BA帧中查找是否有自己的MAC地址，如果发现存在，则说明MAC地址所在的那个确认信息是AP发送给自己的，那么这时存在两种情况，一、若触发帧包括AP分配给每个可使用的子信道的临时标识，则第一STA在接收到触发帧时，已经将该临时标识默认为自己的第一AID，这里的第一AID可以看作是AP分配给第一STA的临时标识，因为，第一STA还没有接收到AP发送给它的关联响应消息，所以，AP分配给它的真实AID(即下面会提到的第二AID)有可能会与第一AID不同，当然，若触发帧包括AP分配给每个可使用的子信道的临时标识，则M-BA帧也可以包括：第二STA对应的所述可使用的子信道的临时标识。二、若触发帧没有包括AP分配给每个可使用的子信道的临时标识，则M-BA帧包括至少一个第二STA的MAC地址和AP分配给第二STA的第一AID，若第一STA查找第一STA的MAC地址在M-BA帧中，则第一STA获取第一STA的MAC地址所对应的第一AID。
具体地，对于第一STA来讲，首先通过M-BA帧中块确认/确认信息中的每个通信标识符中临时标识，或哑关联标识，或特殊TID，或TID中的1比特判断块确认/确认信息是否是关于关联请求消息的确认信息。然后通过每个通信标识符后面跟的MAC地址判断该块确认/确认信息是否是给自己发送的关联请求进行确认的。
S805：第一STA接收AP根据第一AID发送的关联响应消息，其中，关联响应消息用于指示第一STA与AP之间关联建立成功，关联响应消息包括： 第二AID，第二AID用于标识第一STA，第二AID与第一AID相同或者不同。
具体地，由于S804步骤中假设AP成功接收到了第一STA发送的关联请求消息，因此，在S805步骤中，是第一STA接收AP根据第一AID通过OFDMA发送的关联响应消息，其中，关联响应消息所包括的第二AID即为AP分配给它最终真实的AID，以后AP可以通过第二AID与第一STA进行通信。
本发明实施例提供一种关联的建立方法，包括：第一站点STA接收接入点AP广播的触发帧，第一STA接收AP广播的多用户-块确认M-BA帧，若触发帧包括AP分配给每个可使用的子信道的临时标识，则M-BA帧包括至少一个第二STA的MAC地址；若第一STA查找第一STA的MAC地址在M-BA帧中，则第一STA确定关联确认信息为AP发送给自己的确认信息，并将对应的可使用的子信道的临时标识作为自己的第一AID；若触发帧没有包括AP分配给每个可使用的子信道的临时标识，则M-BA帧包括至少一个第二STA的MAC地址和AP分配给第二STA的第一AID，若第一STA查找第一STA的MAC地址在M-BA帧中，则第一STA获取第一STA的MAC地址所对应的第一AID，第二STA为AP成功接收到的关联请求消息对应的STA，第一STA接收AP根据第一AID通过OFDMA发送的关联响应消息，关联响应消息包括第二AID，由于AP在M-BA帧的关联确认信息中携带了MAC地址，因此，只要第一STA读取到了自己的MAC地址，则可以确认该关联确认信息中存在AP发送给它的确认信息，并且获得第一AID，最后再获得第二AID，进而实现AP与STA之间的关联，保证了通信的可靠性。
由于通常一个M-BA帧中可以包括至少一个关联确认信息，也可以包括普通确认信息，该普通确认信息不是针对关联请求消息的确认信息，那么如何区别M-BA帧中的确认信息是关联确认信息还是普通确认信息，下面进行具体介绍：
一、若触发帧包括AP分配给每个可使用的子信道的临时标识，则所述关联确认信息还包括：所述第二STA对应的所述可使用的子信道的临时标识，临时标识还用于表示所述关联确认信息为关于所述关联请求消息的确认信息。这种情况下，由于第一STA已将它当时发送关联请求消息所用的竞争子信道 的临时标识默认为自己的第一AID，因此，当该第一AID接收到M-BA帧后，若读取到M-BA帧中某个BA/ACK Info含有它获取到的默认临时标识，则表明该某个BA/ACK Info为关联确认信息，如图3A所示，第一STA读取每个通信标识符信息之后的MAC地址，然后再判断这个MAC地址是否为自己的MAC地址，若是，则表明AP成功接收到了第一STA的关联请求消息。若该M-BA帧还包括它所对应的可使用的信道的临时标识，则第一STA除了通过MAC地址判断确认信息是否发送给自己，还可以进一步通过临时标识来确认信息是否发送给自己。
二、所述关联确认信息还包括：哑关联标识符，所述哑关联标识符用于表示所述关联确认信息为关于所述关联请求消息的确认信息，其中，哑关联标识符可以用11比特个0来表示，也可以是AP指定的某个特殊的标识符。如图4所示，当第一STA接收到M-BA帧后，如果读取到了哑关联标识符，则认为该M-BA帧中该BA/ACK Info为关联确认信息，并且第一STA读取每个通信标识符信息之后的MAC地址，然后，再判断这个MAC地址是否为自己的MAC地址。若是，则表明AP成功接收到了第一STA的关联请求消息。
三、所述关联确认信息还包括：特殊TID，所述特殊TID用于表示所述关联确认信息为关于所述关联请求消息的确认信息，其中，基于增强的分布式信道访问(Enhanced Distributed Channel Access，简称EDCA)技术，M-BA帧中的TID通常为8种，而这8种只需要占用3比特就可以了，然而，每个通信标识符信息中的TID分配了4个比特位，因此，值为0-7的TID可以指示正常的TID，值为8-15的TID即为特殊的TID，因此，特殊的TID可表示块确认/确认信息为关于关联请求消息的确认信息。如图5所示，当第一STA接收到M-BA帧后，如果读取到了特殊TID，则认为该M-BA帧中该BA/ACK Info为关联确认信息，并且第一STA读取每个通信标识符信息之后的MAC地址，然后，再判断这个MAC地址是否为自己的MAC地址。若是，则表明AP成功接收到了第一STA的关联请求消息。
四、所述关联确认信息还包括：关联确认指示，所述关联确认指示为每个通信标识符字段里的TID子字段的1比特，用于表示所述关联确认信息为关于所述关联请求消息的确认信息，如图23所示，当第一STA接收到M-BA帧后，如果读取到了关联确认指示，若该比特指示为关联确认信息，则认为 该M-BA帧中该BA/ACK Info为关联确认信息，并且第一STA读取每个通信标识符信息之后的MAC地址，然后，再判断这个MAC地址是否为自己的MAC地址。若是，则表明AP成功接收到了第一STA的关联请求消息。同时该STA也获取了AP通过M-BA在每个通信标识符字段里的AID子字段中分配的第一AID。
进一步地，由于一个M-BA帧中的某个BA/ACK Info可能包括对多个未关联STA发送的的关联请求的确认，即M-BA帧中包括有一个BA/ACK Info，该BA/ACK Info包括对多个未关联STA发送的关联请求的确认，如图6所示，该M-BA帧中包括一个BA/ACK Info，该块确认信息中包括有多个MAC地址和与该MAC地址对应的临时标识或者第一AID，那么如何确定AP通过同一条关联确认信息向多少个STA进行确认，下面进行具体介绍可以通过以下方式确认：
一、所述关联确认信息中的特殊通信标识符TID或TID的全部4比特表示所述AP通过同一条所述关联确认信息向多少个第二STA进行确认。当然，这种情况不能基于上述第三种情况。
二、M-BA帧还包括：统计标识符，所述统计标识符表示所述AP通过同一条所述关联确认信息向多少个第二STA进行确认。其中，所述统计标识符位于所述M-BA帧中的每个通信标识符信息之后。或者，所述统计标识符占用所述M-BA帧中的块确认起始序列控制中所保留的比特位。
需要说明的是，本发明实施例中，每个通信标识符信息之后，若跟MAC地址，或者还包括临时标识/第一AID，或者是多个MAC地址，多个临时标识/第一AID。此时需要通过填0来保证上述内容所需的比特数是8的倍数，即以字节为单位，或者也可以以10字节为单位。
下面介绍关联的建立过程：
图9为本发明一实施例提供的发送关联请求消息和关联确认消息的示意图，这里的关联确认消息可以理解为包括有至少一个关联确认信息的M-BA帧，如图9所示，AP广播触发帧，该触发帧指示可使用的信道为子信道1至子信道9，其中，STA1和STA2通过子信道8发送各自的关联请求消息，然后，AP广播M-BA帧，M-BA帧包括至少一个关联确认信息，关联确认信息为关于关联请求消息的确认信息，这时STA1在读取某个关联确认信息后， 查找到了自己的MAC地址，STA1确定AP已经成功接收到了它所发送的关联请求消息，该M-BA帧中包括有对它的确认信息，并且获得第一AID。
通常，当STA接收到AP向它发送的关联响应消息之后，可以向AP发送一个上行确认消息，图10为本发明一实施例提供的发送关联响应消息和确认消息的示意图，如图10所示，AP通过下行OFDMA向STA1发送关联响应消息，下行OFMDA中的资源指示比特通过临时标识(第一AID)指示STA1在某个子信道接收关联响应，图10所示，该子信道为子信道8，可以理解的是，该子信道选择方法取决于STA1在哪个子信道上接收较优。
图11为本发明再一实施例提供的一种关联的建立方法的流程图，该方法的执行主体为AP，其中该方法具体包括如下流程：
S1101：接入点AP接收至少一个第一站点STA中的每个第一STA发送的关联请求消息，关联请求消息包括第一STA生成的令牌标识，令牌标识用于唯一标识第一STA；
S1102：AP广播多用户-块确认M-BA帧，所述M-BA帧包括至少一个关联确认信息，所述关联确认信息为关于所述关联请求消息的确认信息；其中，关联确认信息包括至少一个第二STA的令牌标识和AP向第二STA分配的第一关联标识AID，以使第二STA根据令牌标识获取第一AID，第二STA为AP成功接收到的关联请求消息对应的第一STA；
S1103：AP根据第一AID向对应的第二STA发送关联响应消息，其中，关联响应消息用于指示第二STA与AP之间关联建立成功，关联响应消息包括：第二AID，第二AID用于标识第二STA，第二AID与第一AID相同或者不同。
具体地，AP根据第一AID通过OFDMA方式向对应的第二STA发送关联响应消息，通常每个第一STA生成的令牌标识占用11比特位，因此，一般它们互不相同，当AP接收到第一STA发送的关联请求消息后，则会获得每个第一STA的令牌标识，由于该令牌标识有可能会存在与AP已将向其他关联的STA的AID相同，因此，这时，AP会对每个第一STA分配一个第一AID，并广播M-BA帧，关联确认信息中包括至少一个第二STA的令牌标识和AP向第二STA分配的第一关联标识AID，当某个第一STA查找到了自己的令牌标识，则说明AP接收到了它的关联请求消息，并且可以继续读取 M-BA帧，获得第一AID。最后，AP根据第一AID通过OFDMA向对应的第二STA发送关联响应消息，其中，关联响应消息用于指示第二STA与AP之间关联建立成功，关联响应消息包括：第二AID。
本发明实施例提供一种关联的建立方法，该方法中AP根据第一STA的令牌标识为第一STA分配了第一AID，那么第一STA只要读取到自己的令牌标识就可以获得第一AID，最后，AP再根据第一AID为第一STA分配了第二AID，从而实现AP与第一STA之间的关联，进而保证通信的可靠性。
进一步地，上述关联请求消息还包括第一STA的MAC地址。因此，关联确认信息还可以包括第二STA的MAC地址。图12本发明一实施例提供的M-BA帧结构示意图六，如图12所示，该M-BA帧中包括令牌标识，以及第一AID，其中，令牌标识还有一个作用，就是它可以表示它所在的关联确认信息为关于关联请求消息的确认信息，可选地，还包括MAC地址。图13本发明一实施例提供的M-BA帧结构示意图七，如图13所示，该M-BA帧中包括多个令牌标识，以及多个第一AID，以及哑关联标识符，这里的哑关联标识符用于标识它所在的关联确认信息为关于关联请求消息的确认信息。其中，哑关联标识符可以用11比特个0来表示，也可以是AP指定的某个特殊的标识符。可选地，还可以包括多个MAC地址。
需要说明的是，本发明实施例中，每个通信标识符信息之后，若包括令牌标识和第一AID，可选包括MAC地址，或者多个令牌标识和多个第一AID，可选包括多个MAC地址，此时需要通过填0来保证上述内容所需的比特数是8的倍数，即以字节为单位，或者也可以以10字节为单位。
更进一步地，可以通过M-BA帧中某个关联确认信息的令牌标识，确定该关联确认信息为关于所述关联请求消息的确认信息，也可以哑关联标识符，或者特殊通信标识符TID来表示M-BA帧为关联请求消息的确认信息。具体和上述实施例中的方式相同，在此不再赘述。
更进一步地，可以通过M-BA帧中某个关联确认信息的通信标识符TID中的1比特关联确认指示，确定该关联确认信息为关于所述关联请求消息的确认信息。
可选地，所述关联确认信息中的特殊通信标识符TID或TID的全部4比特表示所述AP通过同一条所述关联确认信息向多少个第二STA进行确认。
可选地，所述关联确认信息还包括：统计标识符，统计标识符表示所述AP通过同一条所述关联确认信息向多少个第二STA进行确认。所述统计标识符位于所述关联确认信息中的每个通信标识符信息之后，或者所述统计标识符占用所述关联确认信息中的块确认起始序列控制中所保留的比特位。具体和上述实施例中的方式相同，在此不再赘述。
图14为本发明又一实施例提供的一种关联的建立方法的流程图，该方法的执行主体为第一STA，该方法具体包括如下流程：
S1401：第一站点STA生成令牌标识，令牌标识用于唯一标识第一STA；
S1402：第一STA向接入点AP发送关联请求消息，关联请求消息包括第一STA生成的令牌标识；
S1403：第一STA接收AP广播的多用户-块确认M-BA帧，所述M-BA帧包括至少一个关联确认信息，所述关联确认信息为关于所述关联请求消息的确认信息，其中，关联确认信息包括至少一个第二STA的令牌标识和AP向第二STA分配的第一关联标识AID，第二STA为AP成功接收到的关联请求消息对应的STA；
S1404：若第一STA查找自己的令牌标识在M-BA帧中，则获取自己的令牌标识所在的关联确认信息的第一AID；
S1405：第一STA接收AP根据第一AID发送的关联响应消息，其中，关联响应消息用于指示第一STA与所述AP之间关联建立成功，关联响应消息包括：第二AID，所述第二AID用于标识第一STA，第二AID与第一AID相同或者不同。
具体地，第一STA生成的令牌标识占用11比特位，第一STA接收AP发送得M-BA帧时，首先查看自己的令牌标识是否在该M-BA帧中某个BA/ACK Info中每个通信标识符信息中，如果在的话，则第一STA继续读取在每个通信标识符信息之后的第一AID，该第一AID是AP分配给自己的，然后，第一STA接收AP通过OFDMA方式根据第一AID发送的关联响应消息，其中，关联响应消息用于指示第一STA与所述AP之间关联建立成功，关联响应消息包括：第二AID，所述第二AID用于标识第一STA，第二AID与第一AID相同或者不同。
本发明实施例提供一种关联的建立方法，该方法中第一STA生成令牌标 识，以使AP根据第一STA的令牌标识为第一STA分配了第一AID，那么第一STA只要读取到自己的令牌标识就可以获得第一AID，此时第一STA转换成第二STA。最后，AP再根据第一AID通过OFDMA向第二STA发送关联响应，并为其分配了第二AID，从而实现AP与第一STA之间的关联，进而保证通信的可靠性。
进一步地，上述关联请求消息还包括第一STA的MAC地址。因此，所述关联确认信息还包括所述第二STA的MAC地址。
更进一步地，可以通过M-BA帧中某个关联确认信息的令牌标识，确定该关联确认信息为关于所述关联请求消息的确认信息，也可以哑关联标识符，或者特殊通信标识符TID来表示M-BA帧为关联请求消息的确认信息。具体和上述实施例中的方式相同，在此不再赘述。
更进一步地，可以通过M-BA帧中某个关联确认信息的通信标识符TID中的1比特关联确认指示，确定该关联确认信息为关于所述关联请求消息的确认信息。
