技术领域
本发明实施例涉及通信技术，尤其涉及一种无线通信方法和设备。
背景技术
在无线局域网(WLAN)通信标准802.11ac及更早无线保真(Wireless Fidelity，简称WiFi)标准中，站点(Station，简称STA)或接入点(Access Point，简称AP)发送数据时，会在该数据的MAC头中设置响应该数据的确认策略。接收该数据的接收端根据该确认策略进行相应响应。
在新一代的WLAN通信标准802.11ax中，引进了正交频分多址接入技术(orthogonal frequency division multiple access，简称OFDMA)。多站点在不同子信道接收或发送数据。对于下行数据传输(AP向站点发送数据)，AP利用OFDMA技术在不同正交子信道上传输数据给多个站点，多站点通过上行OFDMA回复块确认(Block acknowledgement，简称BA)或确认(Acknowledgement，简称ACK)，以响应接收到的数据。对于上行数据传输(站点向AP发送数据)，AP先发送触发帧，该触发帧用于使多站点同步发送数据，多站点接收到该触发帧后，通过OFDMA在不同的正交子信道传输数据给AP，AP接收到多站点同时传输的数据时，可以以OFDMA BA或ACK形式进行确认。
其中，多个STA利用OFDMA技术在相应子信道上传输聚合MAC协议数据单元(aggregate MAC protocol data unit，简称A-MPDU)，A-MPDU由MAC服务数据单元(MAC service data unit，简称MSDU)或聚合MAC服务 数据单元(aggregate-MSDU，简称A-MSDU)前添加MAC头封装而成的MPDU聚合而成，A-MPDU包含的MSDU或A-MSDU只能对应一种通信标示符(traffic identifier，简称TID)的业务，其TID值位于每个MPDU的MAC头中的服务质量(Quality of Service，简称QoS)控制字段中。在增强分布式信道接入(enhanced distributed channel access，简称EDCA)机制中，有4种接入类别(access category，简称AC)，分别为背景(Background，简称BK)，尽力而为(best effort，简称BE)，视频(video，简称VI)和话音(voice，简称VO)，每种AC包含2种TID值的业务，即共有8种TID值业务。每个站点的缓冲储存有限的TID值业务。上行OFMDA数据传输中，根据传输机会(transmit opportunity，简称TXOP)的接入类别以及TXOP共享机制，站点选择一个TID的业务的MSDU进行封装成MPDU，进一步聚合而成A-MPDU。图1为上行OFDMA数据传输示意图，如图1所示，STA2传输的A-MPDU需要的传输时间最长，由于多个站点传输的数据需要在时间上对齐，因此其他站点需用填充(pad)比特进行对齐，以保证图1所示的数据仅包含一种TID值的业务。
上述过程中，多站点与AP在相同时间段内进行通信的数据(A-MPDU)只能包含一种TID业务，因此，当各个站点需要传输的一种TID业务的数据的时间不同时，需要使用填充比特以保证多个站点传输的数据在时间上对齐，这样的传输方式会造成资源浪费，然而，对于无线局域网通信标准的不断发展，为了更好利用资源，需要允许多站点与AP在相同时间段内进行通信的数据(A-MPDU)包含多TID的业务，因此要重新设计确认流程，以及相应的帧结构。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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作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。
图2为本发明各实施例的一种应用场景示意图，如图2所示，本发明各实施例的应用场景可以包括多个AP和多个STA，其中，一个AP可以与多个STA建立无线连接，AP可以接入网络，具体的，STA可以是手机、平板电脑等终端设备。本发明各实施例涉及的方法为STA与AP进行数据传输过程中的确认机制。
本发明权利要求书中和发明内容中的块确认请求帧即为下述实施例中的MU-Multi-TID BAR帧或Multi-TID BAR帧或BAR帧。本发明权利要求和发明内容中的块确认帧即为下述实施例中的Multi-TID BA帧或BA帧或多站点多TID块确认帧(Multi-TID M-BA帧)。本发明权利要求书中和发明内容中的块确认请求触发帧即为下述实施例中的MU-Multi-TID BAR Poll帧。还需要说明的是本发明中下行或上行聚合数据帧包括的MSDU可以替换为聚合MSDU(A-MSDU)、MSDU分片或聚合MSDU分片(A-MSDU分片)，其均可以利用本发明实施例的方法实现数据确认机制。
图3为本发明无线局域网中的通信方法实施例一的示意图，如图3所示，本实施例的示意图具体为下行聚合数据帧的传输，具体的，AP通过OFDMA技术在相同时隙不同子信道上向4个STA发送下行聚合数据帧，例如，AP可以通过信道1传输下行聚合数据帧给STA1，而通过信道2传输下行聚合数据帧给STA2，通过信道3传输下行聚合数据帧给STA3，通过信道4传输下行聚合数据帧给STA4，发给各个STA的下行聚合数据帧的确认策略可以不同也可以相同，且发给各STA的下行聚合数据帧可以是单TID也可以是多TID。
具体的，在下行聚合数据帧的MAC头中的QoS控制字段(QoS control field)里的比特5-6(比特位是从0开始)的确认策略(Acknowledgement， ACK Policy)子字段里设置响应该下行聚合数据帧的确认策略。该确认策略子字段含有2比特，包含4种确认策略。其中，“00”表示正常ACK或隐式的块确认(Block acknowledgement，简称BA)请求，具体的，若发送的下行聚合数据帧是非多个MPDU聚合A-MPDU时，则接收端响应ACK，或者QoS+CF-ACK帧，若发送的下行聚合数据帧是A-MPDU时，则接收端响应BA。“10”表示该发送的数据不需确认。“01”表示非显式ACK或节能轮询(Power-Save Multi-Poll，简称PSMP)下的调度ACK。“11”表示BA，接收端接收到数据后，除了记录接收状态不做任何立即响应，该接收端会期待后面接收一个BA请求帧(BA request，简称BAR)或一个确认策略为“00”的A-MPDU数据，然后再响应BA。
本实施例以AP发送给部分STA的下行聚合数据帧的确认策略设置为BA“11”，部分STA的下行聚合数据帧的确认策略设置为“00”，本实施例仅以此做示意性解释说明，并不以此作为限制。具体的，AP发送给STA1的下行聚合数据帧为单TID的A-MPDU，确认策略为“00”，AP发送给STA2的下行聚合数据帧为多TID的A-MPDU，确认策略为“00”，AP发给STA3的下行聚合数据帧为多TID的A-MPDU，确认策略为“11”，AP发给STA4的下行聚合数据帧为单TID的A-MPDU，确认策略为“11”。那么，如图3所示，STA1和STA2收到AP发送的下行聚合数据帧后，通过OFDMA分别发送BA确认帧和Multi-TID BA确认帧，在另一个时隙，AP发送MU-Multi-TID BAR帧触发STA3和STA4发送确认帧，STA3和STA4收到MU-Multi-TID BAR帧后通OFDMA分别发送Multi-TID BA确认帧和BA确认帧。
与图3所示示意图不同，AP发送给各STA的下行聚合数据帧的确认策略均为BA“11”，图4为本发明无线局域网中的通信方法实施例二的示意图，如图4所示，AP通过下行OFDMA发送下行聚合数据帧给4个STA，4个STA收到下行聚合数据帧后，均不立即响应确认帧，而是等到AP发送MU-Multi-TID BAR帧后再回复确认帧，这里假设每个STA收到的下行聚合数据帧均是由多TID的MSDU封装成的MPDU聚合而成，那么4个STA在另一个时隙通过上行OFDMA同时反馈Multi-TID BA。
下面对图3和图4中的MU-Multi-TID BAR的具体结构进行解释说明。
需要说明的是本发明实施例中的“中文/中文”、“英文/英文”表示或的意思，例如时长/身份表示时长或身份。本发明实施例中的“中文/英文”则表示中文对应的英文。
图5为本发明一种MU-Multi-TID BAR帧结构的示意图，如图5所示，该MU-Multi-TID BAR帧具体包括帧控制(frame control)字段，时长/身份(Duration/ID)字段，接收地址(receive address，RA)字段，发送地址(transmit address，TA)字段，BAR控制(BAR control)字段，站点1触发信息(trigger info for STA1)字段，站点1的BAR信息(BAR info for STA1)字段，……，站点n触发信息(trigger info for STAn)字段，站点n的BAR信息(BAR info for STAn)字段，以及帧校验(frame check sequence，FCS)字段。其中，接收地址RA为广播地址。
进一步的，每个站点的BAR信息字段包括通信标识符字段和重复的BA的起始控制序列字段，通信标识符字段(TID info)结构具体如图6所示，图6为本发明通信标识符字段的结构示意图，如图6所示，通信标识符字段包括TID位图(TID bitmap)字段，可选的还可以包括保留(Reservesd)字段，其中，由于有8中TID值业务，所以，这里可以设计TID位图(TID bitmap)字段为8比特，每一个比特与一种TID值对应，每个比特位有两种状态值，该状态值用于指示下行聚合数据帧的TID是否包括比特位对应的通信标识符，例如，第一个比特位与TID 0对应，第二个比特位与TID 1对应，依次类推，第8个比特位与TID 7对应，比特位为1用于表示包括，比特位为0用于表示不包括，那么，若TID位图(TID bitmap)字段具体为“10100000”，则表示下行聚合数据帧中含有TID 0和TID 2的MSDU。
进一步的，上述起始序列控制字段(Starting sequence control)包括多个TID的起始序列控制字段，如图7所示，图7为本发明起始序列控制字段的结构示意图，具体的可以包括TID 0的起始序列控制字段(Starting sequence control for TID 0),……,TIDn的起始序列控制字段(Starting sequence control for TIDn),以上述举例做进一步解释说明，即通信标识符字段中的TID位图(TID bitmap)字段为“10100000”，那么起始序列控制字段包括TID 0的起始序列控制字段和TID 2的起始序列控制字段。进一步的，每一个TID的起始序列控制字段可以如图8所示，图8为本发明一个TID的起始序列控制字 段的结构示意图，如图8所示，包括保留(Reserved)字段和起始序列号(starting sequence number)字段，其中起始序列号指示待确认的A-MPDU的其中一个TID的第一个MPDU包含的MSDU的序列号。
进一步的，图9为本发明MU-Multi-TID BAR帧中的BAR控制字段的结构示意图，如图9所示，BAR控制字段可以包括块确认/确认策略位(BA/ACK policy)字段，多个-通信标识符位(Multi-Traffic Identifier，简称Multi-TID)字段，压缩位图位(compress bitmap)字段，保留(Reserved)字段，和通信标识符/通信标识符个数(Traffic Identifier/Number Traffic Identifier，TID/Num TIDs)字段。
其中，BAR控制字段中的保留(Reserved)字段和可重用的其他字段中的1比特或多比特中任意一个或其组合，可以用于指示触发的上行多站点传输的物理层汇聚过程协议数据单元(physical layer convergence procedure protocol data unit，简称PPDU)所需的最长时间或上行多站点传输的PPDU的最长长度，例如使用8比特指示PPDU长度。可选的，在BAR控制字段中，可以使用Multi-TID字段,compress bitmap字段和组播重传字段(Groupcast with retries，简称GCR)的3比特组合指示的保留比特指示该新BAR帧类型，即增加一种新的BAR帧类型：多站点Multi-TID BAR，另一种方式是通过BAR控制字段中的保留位指示该BAR帧类型为多站点Multi-TID BAR帧。站点可以通过BAR帧类型指示比特位(Multi-TID字段，compressed bitmap字段和GCR字段的组合比特或者BAR控制字段中保留位)获知BAR帧类型，其中，当指示BAR帧为Multi-TID BAR帧或多站点Multi-TID BAR时，TID/Num TID字段表示通信标识符个数，否则表示通信标识符，具体的，当具有多个通信标识符时，TID/Num TID字段表示通信标识符个数，当仅具有一个通信标识符时，TID/Num TID字段表示该通信标识符。
进一步的，对于资源分配方式可以包括集中式资源分配和分布式资源分配。集中式资源分配具体指给多个站点联合进行资源指示，资源指示信息放在公有域，具体的实现方式可以为，BAR控制字段中还可以包括联合资源指示信息，用于给多个站点联合进行资源指示，可选的可以包括上行传输的保护间隔(guard interval，GI)，带宽(bandwidth，BW)，高效信令长训练字段(High efficiency long training field，HE-LTF)的数目，HE-LTF类型。分 布式资源分配具体指给多个站点独立进行资源指示，资源指示信息分别放在每个站点信息中，具体的实现方式可以为，将每个站点的资源指示信息放在每个站点触发信息(trigger info for STAn)字段。
进一步的，每个站点触发信息字段还可以包括站点的关联标识(association identifier，简称AID)，发送功率，空间流数，调制与编码策略(Modulation and Coding Scheme，简称MCS)，编码类型，是否使用时分空时码(STBC)指示以及是否使用波束成型技术(beamforming)指示等参数中的一个或多个。
图10为本发明另一种MU-Multi-TID BAR帧结构的示意图，如图10所示，该MU-Multi-TID BAR帧具体包括帧控制(frame control)字段，时长/身份(Duration/ID)字段，接收地址(receive address，RA)字段，发送地址(transmit address，TA)字段，公有(common)字段，站点1触发信息(trigger info for STA1)字段，站点1的BAR控制(BAR control for STA1)字段，站点1的BAR信息(BAR info for STA1)字段，……，站点n触发信息(trigger info for STAn)字段，站点n的BAR控制(BAR control for STAn)字段，站点n的BAR信息(BAR info for STAn)字段，以及帧校验(frame check sequence，FCS)字段。其中，接收地址RA为广播地址。公有(common)字段包括TID个数字段，用于指示所有站点的TID个数的和。
其中，对于每个站点的BAR控制字段中的TID个数/TID值字段指示该站点下的TID个数/TID值，BAR信息字段包括因多TID出现的重复通信标识符信息字段和起始序列控制字段，具体的BAR信息(BAR info)字段可以如图11所示，图11为本发明BAR信息字段的结构示意图，如图11所示，BAR信息字段包括TID 0的信息(per TID 0info)字段，TID 0的起始序列控制(starting sequence control for TID1)字段，……，TIDn的信息(per TIDn info)字段，TIDn的起始序列控制(starting sequence control for TIDn)字段。其中，每一个TID的信息字段可以包括站点的AID字段，保留字段，以及TID字段，具体的结构可以参见图12，图12为本发明一个TID的信息字段的结构示意图。
进一步的，对于资源分配方式可以包括集中式资源分配和分布式资源分配。集中式资源分配具体指给多个站点联合进行资源指示，资源指示信息放 在公有域，具体的实现方式可以为，公有(common)信息字段中包括联合资源指示信息，用于给多个站点联合进行资源指示，可选的还可以包括触发的上行多站点传输的物理层汇聚过程协议数据单元(physical layer convergence procedure protocol data unit，PPDU)所需的最长时间或上行多站点传输的PPDU最长长度，例如使用8比特指示PPDU长度，上行传输的保护间隔(guard interval，GI)，带宽(bandwidth，BW)，高效信令长训练字段(High efficiency long training field，HE-LTF)的数目，HE-LTF类型等。分布式资源分配具体指给多个站点独立进行资源指示，资源指示信息分别放在每个站点信息中，具体的实现方式可以为，将每个站点的资源指示信息放在每个站点触发信息(trigger info for STAn)字段。
进一步的，每个站点触发信息字段还可以包括站点的关联标识(association identifier，简称AID)，发送功率，空间流数，调制与编码策略(Modulation and Coding Scheme，简称MCS)，编码类型，是否使用时分空时码(STBC)指示以及是否使用波束成型技术(beamforming)指示等参数中的一个或多个。
需要说明的是，本发明实施例具体示出了两种MU-Multi-TID BAR帧结构，然而本发明并不以此限制，具体的，根据上述图5和图10的两种结构，可以将字段进行重新组合，以获取更多帧体结构，本发明实施例此处不作一一说明。
图5和图10给出了多站点多TID的BAR帧结构，上述帧结构也可以退化为单站点多TID的BAR帧，该多个单站点多TID的BAR帧通过正交子信道同时发送，达到多站点多TID的BAR功能。
其中，OFDMA Multi-TID BAR帧结构如图26所示，为上述提到的确认方式(1)中在正交子信道上传输的BAR帧的变体，以支持对多TID的聚合数据帧A-MPDU的确认请求。该Multi-TID BAR帧结构类型可以通过BAR控制字段中的保留比特指示，也可以通过多TID字段(multi-TID)，压缩位图字段(compress bitmap)，组播重传字段(Groupcast with retries，简称GCR)的3比特组合指示的保留位指示。即本实施例可以通过上述字段增加一种BAR帧类型。为了支持每个用户发送的上行数据帧为多通信标识符数据帧，本发明提出OFDMA多TID块确认请求帧(OFDMA Multi-TID BAR帧)结 构，如图26所示，该OFDMA Multi-TID BAR帧具体包括帧控制字段(Frame Control)，时长/ID字段(duration/ID)，接收地址字段(RA)，发送地址字段(TA)，BAR控制字段(BAR Control)，每个TID信息(Per TID Info，也可以称为Per AID Info)字段，块确认起始序列控制字段和帧校验序列字段(FCS，frame check sequence)。
具体的，每个TID信息(Per TID Info，也可以称为Per AID Info)字段包括TID位图字段。其中TID位图字段指示该站点发送A-MPDU含有的多个TID，该TID位图字段的具体解释可以参见上述实施例中的TID位图字段的具体解释。比如说，A-MPDU中，则TID位图为“1001000”。后面紧跟对应置“1”的多个TID的起始序列控制字段(BA starting sequence control)。其中，每个起始序列控制字段包括每个TID的MSDU的起始序列号。
图13为本发明无线局域网中的通信方法实施例三的示意图，如图13所示，本实施例与图3所示实施例的区别在于，AP发送的不是MU-Multi-TID BAR帧，而是通过下行OFDMA发送多个Multi-TID BAR帧。具体的，如图13所示，AP通过下行OFDMA发送下行聚合数据帧给4个站点，与图3假设相同，即AP发送给STA1的下行聚合数据帧为单TID的A-MPDU，确认策略为“00”，AP发送给STA2的下行聚合数据帧为多TID的A-MPDU，确认策略为“00”，AP发给STA3的下行聚合数据帧为多TID的A-MPDU，确认策略为“11”，AP发给STA4的下行聚合数据帧为单TID的A-MPDU，确认策略为“11”，STA1和STA2收到AP发送的下行聚合数据帧后，通过OFDMA分别发送BA确认帧和Multi-TID BA确认帧，在另一个时隙，AP通过OFDMA的形式分别发送Multi-TID BAR帧和BAR帧触发STA3和STA4发送确认帧，STA3和STA4收到Multi-TID BAR帧和BAR帧后通OFDMA分别发送Multi-TID BA确认帧和BA确认帧。其中站点STA回复确认帧(Multi-TID BA确认帧或BA确认帧)采用的参数可以和接收到的Multi-TID BAR或BAR采用的参数一样，比如资源指示信息、MSC等。
图14为本发明无线局域网中的通信方法实施例四的示意图，如图14所示，本实施例与图4所示实施例的区别在于，AP发送的不是MU-Multi-TID BAR帧，而是通过下行OFDMA发送多个Multi-TID BAR帧。具体的，如图14所示，AP通过下行OFDMA发送下行聚合数据帧给4个站点，与图4假 设相同，即各下行聚合数据帧的确认策略均为BA“11”，并且每个下行聚合数据帧均是由多个TID的MSDU封装成的MPDU聚合而成，4个STA收到下行聚合数据帧后，均不立即响应确认帧，在另一个时隙，AP通过OFDMA发送Multi-TID BAR帧(指的是单站点的)触发多站点同时通过OFDMA发送确认帧，由于多站点收到的下行聚合数据帧均为多TID的A-MPDU，因此该确认帧需引入在PSMP中使用的Multi-TID BA帧。需要说明的是，此时下行OFDMA Multi-TID BAR帧不需要携带单播触发信息，包括资源分配指示信息(该资源分配指示信息用来指示多个站点分别在哪个子信道上回复确认帧)，以及指示站点采用哪种MCS，GI，编码类型参数。本实施例的站点回复确认帧采用的参数可以和接收到的Multi-TID BAR参数一样，比如站点1在子信道2收到发给自己的Multi-TID BAR，该Multi-TID BAR采用MCS 2，那么该站点同样在子信道2上回复Multi-TID BA，并且采用MCS 2。
需要说明的是，图13和图14的方案也适用于AP给所有接收站点发送单TID的A-MPDU，当确认策略为“11”时，AP可以通过OFDMA的形式发送给各站点发送BAR，站点采用同样的参数通过OFDMA回复BA。
图15为本发明无线通信方法的一种信令流程图，本实施例具体为下行方向的无线通信方法的信令流程图，本实施例的信令流程图包括AP和多个STA，如图15所示，本实施例的方法包括：
S101、AP在相同时隙不同子信道上向各STA发送下行聚合数据帧。
其中，各下行聚合数据帧可以包括多个通信标识符的MSDU。各下行聚合数据帧还携带有确认策略信息。
S102、接收到确认策略信息为“00”的下行聚合数据帧的STA根据下行聚合数据帧的接收状态向AP回复Multi-TID BA帧或BA帧。
S103、AP广播发送MU-Multi-TID BAR帧。
具体的，AP根据各下行聚合数据帧的确认策略信息生成MU-Multi-TID BAR帧，具体的，AP根据确认策略信息为“11”的下行聚合数据帧生成MU-Multi-TID BAR帧，其中，该MU-Multi-TID BAR帧的具体结构可以如图5或图10所示，该MU-Multi-TID BAR帧携带有需要发送BAR的STA的信息和该STA的下行聚合数据帧中的通信标识符信息。之后执行S104。
S103’、AP利用OFDMA在相同时隙不同子信道上向STA发送 Multi-TID BAR帧。
具体的，S103’是S103的另一中可实现的方式，之后执行S104’。
S104、接收到确认策略信息为“11”的下行聚合数据帧的STA根据下行聚合数据帧的接收状态和MU-Multi-TID BAR帧分别向AP回复Multi-TID BA帧或BA帧。
S104’、接收到确认策略信息为“11”的下行聚合数据帧的STA根据下行聚合数据帧的接收状态和Multi-TID BAR帧分别向AP回复Multi-TID BA帧或BA帧。
本实施例，AP可以通过OFDMA在相同时隙不同子信道上向多个STA发送下行聚合数据帧，该下行聚合数据帧可以包括多个通信标识符的MSDU，AP可以通过发送MU-Multi-TID BAR帧或利用OFDMA分别向STA发送Multi-TID BAR帧，从而使得STA根据AP指示正确完成对接收到的数据帧的确认。上述各实施例均为下行方向的数据传输确认机制，而对于上行方向的数据传输确认机制具体将在下述实施例中解释说明。
图16为本发明无线局域网中的通信方法实施例五的示意图，如图16所示，本实施例的示意图具体为上行数据帧的传输，具体的，AP通过触发(Trigger)帧触发多站点通过上行OFDMA在相同时隙发送上行数据帧(Data)，这里假设多个站点发送的上行数据帧(A-MPDU)的确认策略都设置为BA“11”，也就是说，AP收到多站点发送的上行数据帧后，不会立即响应确认帧，而是等到站点发送BAR帧后再回复BA确认帧。其中，各下行聚合数据帧(A-MPDU)均是由多TID的MSDU封装成的MPDU聚合而成的。可以理解的，也可以部分站点把其发送的下行聚合数据帧(A-MPDU)的确认策略设置为BA“11”，此处以上行数据帧的确认策略均为BA“11”举例说明，如图16所示，AP在等待站点发送BAR帧时，可以广播发送MU-Multi-TID BAR Poll帧，该MU-Multi-TID BAR Poll帧可以用于触发多站点以上行MU-MIMO或上行OFDMA形式在相同时隙发送各站点的Multi-TID BAR，AP在收到多站点发送的Multi-TID BAR后，发送多站点多TID确认帧对收到的OFDMA数据进行确认，该OFDMA数据包括各站点的上行数据帧。
进一步的，本发明的MU-Multi-TID BAR poll帧具体可以为触发帧的一 种，在触发帧类型添加一类MU-Multi-TID BAR poll的帧。可选地，对于MU-Multi-TID BAR poll帧可以简化相应的参数，由于MU-Multi-TID BAR poll触发的固定大小的Multi-TID BAR类型帧，因此诸如PPDU长度，HE-LTF数目，HE-LTF类型，资源分配指示都可以采用默认值，每个站点信息中的发送功率，空间流数，编码类型也可以采用默认值。图17为本发明MU-Multi-TID BAR poll帧的结构示意图，如图17所示，该MU-Multi-TID BAR poll帧包括帧控制(frame control)字段，时长(Duration)字段，接收地址(receive address，RA)字段，发送地址(transmit address，TA)字段，关联标识符集合(AID set)字段，以及帧校验(frame check sequence，FCS)字段，其中，在帧控制字段(frame control)增加一种MU-Multi-TID BAR poll的子类型，或者其他保留字段或者可用字段里增加该MU-Multi-TID BAR poll的子类型。关联标识符集合(AID set)字段里包含多个AID，用来指示哪些站点收到该MU-Multi-TID BAR poll帧后通过OFDMA发送Multi-TID BAR，并且按照AID的顺序采用默认大小的子信道传输Multi-TID BAR。
需要说明的是，上述仅以各下行聚合数据帧(A-MPDU)均是由多TID的MSDU封装成的MPDU聚合而成的作举例说明，本发明实施例并不以此作为限制，具体的，部分站点发送的下行聚合数据帧(A-MPDU)也可以是单TID，那么AP发送MU-Multi-TID BAR poll后，相应站点回复BAR，相同时隙，另外部分站点回复Multi-TID BAR，BAR和Multi-TID BAR触发AP回复多站点多TID确认帧。
需要说明的是，当所有站点发送的都是单TID的A-MPDU数据，AP发送的MU Multi-TID BAR poll(此时，也可称为MU BAR poll)，站点回复BAR，多站点的BAR触发AP回复多站点确认帧。总之，上述针对于MU Multi-TID BAR poll设计的通信流程也适合单TID。
可选的，图18为本发明无线局域网中的通信方法实施例六的示意图，如图18所示，本实施例的示意图具体为上行数据帧的传输，与图16所示实施例不同的是，本实施例中的Multi-TID BAR、BAR均可以和其他上行数据帧或其他MAC帧通过OFDMA混传，具体的，AP可以发送一随机竞争的触发帧，各站点收到该随机竞争的触发帧后，通过退避竞争信道，然后发送相应的业务，例如Multi-TID BAR、上行数据帧和缓冲业务汇报buffer report。进 一步，AP可选地在该随机竞争的触发帧中指示哪些业务参与此竞争，在哪些子信道上发送相应的业务等。
可选的，图19为本发明无线局域网中的通信方法实施例七的示意图，如图19所示，本实施例的示意图具体为上行数据帧的传输，与图16所示实施例不同的是，本实施是通过多个站点中其中一个站点发送Multi-TID BAR，利用该Multi-TID BAR触发对所有站点的上行数据帧进行确认。具体的，如图19所示，各站点通过OFDMA在相同时隙向AP发送上行数据帧，之后，在另一个时隙，其中一个站点向AP发送Multi-TID BAR，该Multi-TID BAR可以指示AP该Multi-TID BAR是触发对多个站点的上行数据帧的确认，具体的，可以在该Multi-TID BAR中通过特定比特对AP进行指示，例如，在该Multi-TID BAR中的BAR控制字段中的保留位，可使用1位比特或者多位比特指示该Multi-TID BAR是触发AP对多个站点的上行数据帧的确认。当然可以理解的也可以使用其他比特为来指示该Multi-TID BAR是触发AP对多个站点的上行数据帧的确认。AP接收到该Multi-TID BAR后，可以通过OFDMA或MU-MIMO对多站点发送的上行数据帧进行确认。
需要说明的是，本发明上述实施例中的AP对上行数据帧的确认，或STA对下行聚合数据帧的确认，均是指接收端(AP或STA)对是否正确接收数据的响应。
需要说明的是，上述仅以各上行聚合数据帧(A-MPDU)均是由多TID的MSDU封装成的MPDU聚合而成的作举例说明，本发明实施例并不以此作为限制，具体的，部分站点发送的上行聚合数据帧(A-MPDU)也可以是单TID的A-MPDU数据，那么单个站点发送Multi-TID BAR触发AP回复多站点多TID确认帧。进一步需要说明的是，当所有站点发送上行聚合数据帧(A-MPDU)都是单TID的A-MPDU数据，单个站点发送BAR触发AP回复多站点确认帧。总之，上述针对于Multi-TID BAR设计的通信流程也适合单TID。
图20为本发明无线通信方法的另一种信令流程图，本实施例具体为上行方向的无线通信方法的信令流程图，本实施例的信令流程图包括AP和多个STA，如图20所示，本实施例的方法包括：
S201、AP广播发送上行数据触发帧。
S202、各STA根据上行数据触发帧在相同时隙不同子信道上发送上行数据帧。
各上行数据帧包括确认策略信息。本实施例以策略信息均为“11”做举例说明。
S203、AP根据上行数据帧的策略信息生成MU-Multi-TID BAR poll帧。
S204、AP广播发送MU-Multi-TID BAR poll帧。
执行S204后执行S205。
S204’、AP广播发送随机竞争触发帧。
具体的，S204’是S204的另一种可实现的方式，执行S204’后执行S205’。
S204”、一个STA向AP发送Multi-TID BAR帧，该Multi-TID BAR帧用于指示AP对所有STA的上行数据帧进行确认。
具体的，S204”是S204的另一种可实现的方式。
S205、各STA在相同时隙不同子信道上向AP发送Multi-TID BAR帧。
S205’、STA通过竞争退避的方式向AP发送Multi-TID BAR帧。
S206、AP对各STA发送的上行数据帧进行确认，发送块确认帧。
本实施例，STA可以通过OFDMA在相同时隙不同子信道上向AP发送上行聚合数据帧，该上行聚合数据帧可以包括多个通信标识符的MSDU，AP可以通过发送MU-Multi-TID BAR poll帧或发送随机竞争触发帧，从而使得STA发送Multi-TID BAR帧，进而正确完成对接收到的数据帧的确认。
本发明上述实施例中的确认帧的具体结构可以如下图所示的帧结构。
图21为本发明一种Multi-TID M-BA帧结构的示意图，为了支持每个用户发送的上行数据帧为多通信标识符数据帧，本发明提出多站点多TID块确认帧(Multi-TID M-BA帧)结构，如图21所示，该Multi-TID M-BA帧具体包括帧控制字段(Control frame)，时长/ID字段(duration/ID)，接收地址字段(RA)，发送地址字段(TA)，BA控制字段(BA Control)，BA/ACK信息字段(BA/ACK Info)和帧校验序列字段(FCS，frame check sequence)。
具体的，AP接收到多个站点发送上行数据帧(OFDMA数据帧或者多用户MU-MIMO数据帧)，AP会对多个站点发送上行数据帧进行确认，具体存在以下2种确认方式：(1)OFDMA ACK：AP通过OFDMA的形式回复确认帧，即在各正交子信道上传输ACK或BA，其中ACK是对单个MPDU (MAC protocol data unite)数据帧确认，而BA是对A-MPDU(aggregate MPDU)数据帧确认。(2)Multi-TID M-BA：AP把串联的确认帧广播给多个站点，即如图21所示的Multi-TID M-BA帧结构，其中BA控制字段包括BA/ACK确认策略(BA/ACK policy)，多TID字段用于指示是否为多TID(multi-TID)，压缩位图字段用于指示是否为压缩位图(compress bitmap)，组播重传(Groupcast with retries，简称GCR)字段，保留比特(reserved)字段和TID信息(TID info)字段，其中TID信息字段用来指示存在多少个BA/ACK信息。
其中，OFDMA Multi-TID BA帧结构如图24所示，为上述提到的确认方式(1)中在正交子信道上传输的BA帧的变体，以支持对多TID的聚合数据帧A-MPDU进行确认。该Multi-TID BA帧结构类型可以通过BA控制字段中的保留比特指示，也可以通过多TID字段(multi-TID)，压缩位图字段(compress bitmap)，组播重传字段(Groupcast with retries，简称GCR)的3比特组合指示的保留位指示。即本实施例可以通过上述字段增加一种BA帧类型。为了支持每个用户发送的上行数据帧为多通信标识符数据帧，本发明提出OFDMA多TID块确认帧(OFDMA Multi-TID BA帧)结构，如图24所示，该OFDMA Multi-TID BA帧具体包括帧控制字段(Frame Control)，时长/ID字段(duration/ID)，接收地址字段(RA)，发送地址字段(TA)，BA控制字段(BA Control)，BA/Ack信息字段(BA/Ack Info)和帧校验序列字段(FCS，frame check sequence)。
具体的，BA/Ack信息字段具体可以包括每个TID信息(Per TID Info，也可以称为Per AID Info)字段、BA/ACK指示位图字段和TID位图字段，可选的包括起始序列控制(BA starting sequence control)字段和BA位图(BA bitmap)字段。其中TID位图字段指示该站点发送A-MPDU含有的多个TID，该TID位图字段的具体解释可以参见上述实施例中的TID位图字段的具体解释。具体来讲，若站点发送的A-MPDU含有多个TID的MSDU，每类TID的MSDU分2种，一种是该类TID的MSDU只有一个，简称单MSDU，另一种是该类TID的MSDU多于一个，简称多MSDU。图19中TID位图指示该A-MPDU中正确接收到的单MSDU对应的TID和至少正确接收到一个的多MSDU对应的TID(或多MSDU对应的TID)，比如说，A-MPDU中还 有TID 0和TID 3的MSDU，则TID位图为“1001000”。对于单MSDU或全部正确接收到的多MSDU回复ACK，后面可以没有起始序列控制字段(BA starting sequence control)和BA位图字段(BA bitmap)，对于至少正确接收到一个MSDU的多MSDU(不包括全部正确接收到的多MSDU)或多MSDU(不包括全部正确接收到的多MSDU)回复BA，后面紧跟起始序列控制字段(BA starting sequence control)和BA位图字段(BA bitmap)。BA/ACK指示位图字段指示上述单MSDU或多MSDU对应的确认类型是ACK还是BA。其中，起始序列控制字段是多MSDU对应的第一个MSDU的序列号。
其中，Multi-TID M-BA帧结构类型可以通过BA控制字段中的保留比特指示，也可以通过多TID字段(multi-TID)，压缩位图字段(compress bitmap)，组播重传字段(Groupcast with retries，简称GCR)的3比特组合指示的保留位指示。即本实施例可以通过上述字段增加一种BA帧类型。
具体的，BA/ACK信息字段(BA/ACK Info)可为多个，每一个BA/ACK信息对应一个站点，其中，BA/ACK信息字段具体可以包括每个TID信息(Per TID Info，也可以称为Per AID Info)字段、BA/ACK指示位图字段和TID位图字段，可选的包括起始序列控制(BA starting sequence control)字段和BA位图(BA bitmap)字段。其中TID位图字段指示该站点发送A-MPDU含有的多个TID，该TID位图字段的具体解释可以参见上述实施例中的TID位图字段的具体解释。具体来讲，若站点发送的A-MPDU含有多个TID的MSDU，每类TID的MSDU分2种，一种是该类TID的MSDU只有一个，简称单MSDU，另一种是该类TID的MSDU多于一个，简称多MSDU。图19中TID位图指示该A-MPDU中正确接收到的单MSDU对应的TID和至少正确接收到一个的多MSDU对应的TID(或多MSDU对应的TID)，对于单MSDU或全部正确接收到的多MSDU回复ACK，后面可以没有起始序列控制字段(BA starting sequence control)和BA位图字段(BA bitmap)，对于至少正确接收到一个MSDU的多MSDU(不包括全部正确接收到的多MSDU)或多MSDU(不包括全部正确接收到的多MSDU)回复BA，后面紧跟起始序列控制字段(BA starting sequence control)和BA位图字段(BA bitmap)。BA/ACK指示位图字段指示上述单MSDU或多MSDU对应的确认类型是ACK还是BA。其中，起始序列控制字段是多MSDU对应的第一个MSDU 的序列号。
另一种实施方式具体为：AP可以使用多站点块确认帧(Multi-STA BA，简称M-BA)帧对接收到的上行多站点数据进行确认，M-BA帧同样包括帧控制字段，时长/ID字段，接收地址字段，发送地址字段，BA控制字段，BA/ACK信息字段和帧校验序列字段。与图21的区别在于1.每个TID信息(Per TID Info，也可以称为Per AID Info)字段包括AID，BA/ACK指示位，TID等子字段。2.该M-BA帧不包括图21所示的BA/ACK指示位位图和TID位图等字段。此时该M-BA不支持对站点发送的多TID聚合数据帧进行确认。
本发明结合M-BA帧，提出如图25所示的多TID多站点确认帧(Multi-TID M-BA)。与图21的区别在于，通过Per TID Info字段的至少1比特指示待确认的站点所发送的聚合数据帧是单TID还是多TID的，如果该比特位指示多TID，则BA/ACK指示位图字段和TID位图字段出现在Per TID Info字段后面，然后再紧跟多个重复的块确认起始序列控制字段和块确认位图字段，具体来说，当某个TID对应多MSDU时，则紧跟对应的块确认起始序列控制字段和块确认位图字段，当多个TID都对应多MSDU时，则紧跟该多个TID的块确认起始序列控制字段和块确认位图字段，当对该TID的MSDU回复ACK时，则后面不会出现该TID的块确认起始序列控制字段和块确认位图字段。如果该比特位指示单TID，则此时该站点对应的BA/ACK信息字段不包括BA/ACK指示位图字段和TID位图字段，与M-BA帧中的站点的BA/ACK info字段结构一样。
Per TID Info字段的至少1比特指示待确认的站点所发送的聚合数据帧是单TID还是多TID的实施方式可以为
1.图25所示的Per TID Info字段中的TID子字段中的1比特位。
2.图25所示的Per TID Info字段中的TID子字段的一个特殊的TID值。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，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/确认信息为待确认的站点所发送的聚合数据帧是否为多TID。
上述实施例不限于每个子信道都发下行或上行聚合数据帧，也可以部分子信道发送的是非聚合数据帧。实施例提到的MU Multi-TID BAR，MU Multi-TID BAR poll帧的名字不限于此，举例说，也可以分别称为为Multi-STA Multi-TID BAR，Multi-STA Multi-TID BAR poll帧。
另外，上述实施例中提到的多站点多TID BAR帧，OFDMA多TID BAR帧，多站点多TID BA，OFDMA多TID BA帧中新增的字段的字节数可以为1个字节或多个字节。
另外，上述实施例中提到的多站点多TID BAR帧，OFDMA多TID BAR帧，多站点多TID BA，OFDMA多TID BA帧中新增的BA/ACK指示位图字段和TID位图字段也可以位于块确认位图字段之后，BA/ACK指示位图字段和TID位图字段的位置可以互换。
