目前并行多用户数据传输技术包括：空域多址(multi-user MIMO，简称为MU-MIMO)技术，正交频分多址(Orthogonal Frequency Division Multiple Access，简称为OFDMA)技术，以及码分域多址(Interleave-Division Multiple-Access，简称为IDMA)技术。
图1是根据相关技术中WLAN基本服务集BSS结构示意图，如图1所示，在WLAN中，一个接入点站点(Access Point，简称为AP)以及与该AP相关联的多个非接入点站点(non-AP Station，简称为non-AP STA)组成了一个基本服务集(Basic Service Set，简称BSS)。
WLAN中所说的并行多用户数据传输一般为多个次节点同时向主节点发送数据，一般称这种为上行多用户(Uplink Multi-User,简称为UL MU)，或者主节点同时给多个次节点发送数据，称之为下行多用户(Downlink Multi-User,简称为DL MU)。通常，主节点为AP或特殊能力non-AP STA，次节点为一般non-AP STA。
在相关技术中，UL MU传输所需的媒介资源由主节点来获取，然后主节点发送调度和信令指示触发上行多用户传输，从而解决上行多用户之间的干扰和同步问题。这样，即使多个non-AP STAs可以互相进行UL MU传输，其资源也是只能够由主节点来进行分配，不能充分利用资源。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本实施例提供了一种无线局域网络站点共享资源的方法，图2是根据本发明实施例的无线局域网络站点共享资源的方法的流程图一，如图2所示，该方法包括以下步骤：
步骤S202：主节点接收持有方节点发送的无线帧，其中，该持有方节点为获取到传输机会(Transmission Opportunity，简称为TXOP)的次节点，该无线帧中携带有上行多用户共享信息；为了更好的进行说明，将获取到传输机会并发送无线帧的该次节点称为持有方节点。
步骤S204：主节点向该持有方节点发送响应于该无线帧的反馈帧，其中，反馈帧中携带有共享次节点的多用户信息，其中，共享次节点为与持有方节点进行上行多用户共享传输的一个或多个次节点。
在上述步骤中，采用了持有方节点获取到传输机会之后，共享给其他的次节点的方式。从而将持有方节点竞争到的资源将进行多用户传输，相比于在相关技术中进行多用户共享传输的资源仅仅依靠主节点来进行分配的技术方案，频谱效率得到了提高。
上述实施例及可选的实施方式是从主节点的角度来进行的描述，下面从持有方节点的角度进行描述。
本发明实施例还提供了一种无线局域网络站点共享资源的方法，图3是根据本发明实施例的无线局域网络站点共享资源的方法的流程示意图二，如图3所示，该流程包括如下步骤：
步骤S302：次节点获取到传输机会，获得传输机会的节点称为持有方节点；
步骤S304：持有方节点向主节点发送无线帧，其中，无线帧中携带有上行多用户共享信息；
步骤S306：持有方节点接收主节点响应于无线帧发送的反馈帧，其中，反馈帧中携带有共享次节点的多用户信息，其中，共享次节点为与持有方节点进行上行多用户共享传输的一个或多个次节点。
上述实施例及可选的实施方式是从主节点和持有方节点的角度来进行的描述，下面从共享次节点的角度进行描述。
本实施例还提供了一种无线局域网络站点共享资源的方法，图4是根据发明实施例的无线局域网络站点共享资源的方法的流程图三，如图4所示，该流程包括如下步骤：

步骤S404：该共享次节点和持有方节点向该主节点并行发送上行数据帧。
通过上述步骤S402和步骤S404之后，主节点就可以向共享次节点通知进行上行多用户共享传输了，在一个可选实施例中，共享次节点可以自行决定不进行上行多用户共享传输。在另一个可选实施中，共享次节点进行了上行多用户共享传输，那么，主节点就接收到了持有方节点和共享次节点并行发送的上行数据帧。
在共享传输中，有可能出现上行数据帧出错的情况，在本实施例中还提供了几种可选的处理方式：
处理方式一：在共享次节点向主节点发送的上行数据帧错误时，主节点向共享次节点发送错误指示信息，其中，错误指示信息用于指示共享次节点进行错误恢复传输；
处理方式二：在持有方节点向主节点发送的上行数据帧错误时，主节点向持有方节点发送错误指示信息，其中，错误指示信息用于指示持有方节点进行错误恢复传输；
处理方式三：在持有方节点向主节点发送的上行数据帧错误时，持有方节点等待错误恢复时间之后进行错误恢复传输过程。
在上述处理方式三中，错误恢复时间可以是一个预先设置的经验值，在一个可选的实施例中，错误恢复时间可以为持有方节点在确定上行数据帧为错误后检测信道的时间。

反馈帧包括帧头、帧体、帧校验部分。
帧头部分包含有：时间长度指示Duration域可以用于指示下次上行无线帧发送的时间长度或持有方节点获取的传输机会的剩余时间信息；发送地址域指示了发送该反馈帧的设备的地址信息；接收地址指示了该反馈帧的接收方，在本发明优选实施方式中，该域设为广播或多播组地址时，用于指示期望多个节点接收该反馈帧；帧控制域包含有帧类型指示，是否有数据缓存待发的指示等信息。
此外，帧体又包括确认/寻呼控制字段和N个多用户控制/确认信息字段，其中每个多用户控制/确认信息字段对应一个节点。每个多用户控制/确认信息字段可以有多种格式，图11是根据本发明可选实施例的多用户控制/确认信息字段的格式示意图，如图11所示，一个反馈帧中可以包含多种格式的多用户控制/确认信息字段。
图11a所例示的多用户控制/确认信息字段格式中包括：
指示了所对应的次节点的用户标识，具体的可以是节点的关联标识(association identify，AID)。寻呼指示，该指示设为真时，表示站点在接下来的上行多用户无线帧中可以进行发送，设为假则不能发送。发送参数指示，可以包括频率资源，流数等指示。数据流标识及确认信息序列控制信息，用于指示是对相应节点的那个数据流的那些序号的数据单元的确认或错误指示。确认信息或错误指示信息，用于对正确的帧接收进行确认，或者当数据发送错误时，用于指示对应发送节点数据发送错误。
图11b所示的多用户控制/确认信息字段格式中可以包括：用户标识、发送参数指示、寻呼指示、数据流标识及确认信息序列控制信息，以及发送调整参数信息。其中发送调整参数信息用于指示对应次节点，在下次发送时，调制发送的功率、时延、频率偏移、以及进行链路自适应，调整调制与编码策略(Modulation and Coding Scheme，简称为MCS)，从而与其他次节点的上行发送保持同步并互不干扰。
实施例二
一个支持多用户传输的AP建立一个BSS，多个non-AP STA与AP进行了关联认证过程，组成一个基本服务集合BSS。在上述关联过程中，AP与站点交互能力信息，其中包括是否支持上行多用户传输能力的指示，本实施例中假设关联站点STA1～3支持上行多用户数据发送，且STA1～3分别与AP进行管理帧交互，达成支持上行多用户共享传输的协商。
图12是根据本发明可选实施例的站点竞争资源进行上行多用户共享示意图一；图12示出了一个STA1竞争到传输机会TXOP，共享进行上行多用户传输的例子。
1.STA1竞争发送上行数据帧1，且在发送的数据帧的帧头部分携带上行多用户共享信息，具体的包括，使能下次传输进行上行多用户共享，指示持有方节点STA1下次发送的无线帧的传输参数信息，具体的，包括发送时间长度信息，STA1发送占用的频率资源、使用的流数等信息。
2.AP收到STA1的数据帧，若该数据帧中使能下次传输进行上行多用户共享，则AP发送多用户响应帧(multi-user block ACK，MU-BA)，使用一个多用户控制/确认字段对STA1数据进行确认，该字段可使用图11中的(a)格式；同时携带针对STA2，STA3的多用户控制/确认字段，其格式可以为图11中的(b)格式，寻呼STA2和STA3进行下一次的多用户并行传输，且在对应的信息字段中指示发送参数(该参数限制STA2、3的发送时长、频率资源、流数，避免相互干扰)、调整参数(功率、频偏、时延调整、链路自适应反馈信息)等信息。
3.STA2和STA3收到反馈帧MU-BA中的多用户控制/确认信息后，确认自己被寻呼进行上行多用户共享传输，则STA2、3按照反馈帧中指示的参数和STA1进行并行传输，例如进行上行OFDMA传输。其中STA1发送的数据中可以继续携带上行多用户共享信息，继续使能下次上行多用户共享传输。
4.AP收到步骤3中发送的上行多用户数据帧后，若STA1的数据帧中的上行多用户共享信息指示了继续使能上行多用户共享，则AP发送反馈帧，对STA1、2、3的数据进行确认并继续寻呼STA2、3进行下一次传输。此时，反馈帧携带的STA1、2、3的多用户控制/确认字段，其格式可以为图11中的(a)格式，对数据进行确认的同时，并利用寻呼指示，指示是否允许下次传输。
需要注意的是反馈帧中必须包含针对STA1的多用户控制/确认字段，且一直允许STA1进行上行传输。当STA1发送的上行多用户共享信息指示不使能下次多用户共享时，AP不能在发送的反馈帧中继续寻呼STA2、3，但是可以对STA2、3的上次发送的数据进行确认。
另外AP发送的反馈帧中的发送参数应与该反馈帧对应的STA1的数据帧中携带的发送参数保持一致或不冲突。具体的，AP在反馈帧中确定的下一帧发送时长应与STA1指示的发送时长相同；AP在反馈帧中指示的STA2、3的频率资源、流数等信息应与STA1占用的频率资源、流数正交互不干扰。
另外，AP在一个TXOP内首次寻呼一个共享站点时，可以指示发送的频率资源、流数等参数和调整参数，非首次寻呼时，则可以不携带这些信息，这些站点按照首次指示的参数进行发送。
实施例三
图13是根据本发明可选实施例的站点竞争资源进行上行多用户共享示意图二，图13示出了一个STA1竞争到TXOP，共享进行上行多用户传输的例子。
1.STA1竞争发送上行数据帧1，且在发送的数据帧的帧头部分携带上行多用户共享信息，具体的包括，使能下次传输进行上行多用户共享，指示持有方节点STA1获取的TXOP的剩余时间信息。
2.AP收到STA1的数据帧，若该数据帧中使能上行多用户共享，则AP发送多用户响应帧(MU-BA)，使用一个多用户控制/确认字段对STA1数据进行确认，该字段可使用图11中的(a)格式；同时携带针对STA 2，STA3的多用户控制/确认字段，其格式可以为图11中的(b)格式，寻呼STA2和STA3进行下一次的多用户并行传输。其中AP确定并指示各个站点的发送参数，例如指示了下次上行多用户传输的发送时长信息，并确定每个站点的发送的频率资源、流数。
3.STA2和STA3收到反馈帧MU-BA中的多用户控制/确认信息后，确认自己被寻呼进行上行多用户共享传输，则STA2、3按照反馈帧中指示的参数和STA1进行并行传输，例如进行上行MU-MIMO传输。
4.AP收到步骤3中发送的上行多用户数据帧后，若STA1获取的传输机会足够进行下一次多用户传输过程，则AP发送反馈帧，对STA1、2、3的数据进行确认并继续寻呼下一次传输。此时，反馈帧携带的STA1、2、3的多用户控制/确认字段，其格式可以为图11中的(a)格式，对数据进行确认的同时，并利用寻呼指示，指示是否允许下次传输。
需要注意的是反馈帧中必须包含针对STA1的多用户控制/确认字段，且一直允许STA1进行上行传输。AP要保证所有的传输在TXOP结束前完成。
另外AP发送的反馈帧中的发送参数可以由AP根据各个站点的情况决定。具体的，AP在反馈帧中通知下一帧发送时长，STA1、2、3的频率资源、流数，所有站点按照AP指示的参数进行发送。
实施例四
图14是根据本发明可选实施例的共享次节点数据发送错误的恢复过程示意图，如图14所示的，站点STA1竞争到TXOP，共享进行上行多用户传输时，共享次节点的数据发送错误时的错误恢复过程。
STA1和STA2、3进行上行多用户发送给AP，其中共享次节点STA2的数据发送错误，STA1、STA3的数据发送正确。AP在发送反馈帧时，携带对STA1和STA3的确认信息，并携带对STA2的错误指示信息，并指示继续进行上行多用户传输。则STA1、STA2、STA3继续并行传输给AP，其中STA2可以进行重传恢复。综上所述，共享次节点(例如STA2)要等待AP发送错误指示才可以进行重传恢复。另外，AP在反馈帧中发送错误指示给STA2的同时也可以指示发送参数和/或调整参数信息。
若STA1在发送的无线帧中，指示了不使能上行多用户共享，则即使共享次节点的数据发送错误，AP也不能发送错误指示触发共享次节点的重传恢复。
实施例五
图15是根据本发明可选实施例的持有方节点数据发送错误的恢复过程示意图一，如图15所示，站点STA1竞争到TXOP，共享进行上行多用户传输时，持有方节点的数据发送错误时的错误恢复过程。
STA1和STA2、3进行上行多用户发送给AP，其中STA1的数据发送错误，STA2、STA3的数据发送正确。AP可以在短帧间间隔(short interframe space，SIFS)后发送反馈帧，该帧中携带对STA2和STA3的确认信息，同时可以指示STA2、3不能继续进行上行多用户传输，并携带对STA1的错误指示信息。STA1在收到错误指示后立即进行重传恢复。
AP可以主动发送错误指示给持有方节点，触发持有方节点进行重传恢复。另外，AP发送的反馈帧中必须包含针对STA1的信息字段，不可以只携带STA2和STA3的确认信息。
实施例六
图16是根据本发明可选实施例的持有方节点数据发送错误的恢复过程示意图二，如图16所示，站点STA1竞争到TXOP，共享进行上行多用户传输时，持有方节点的数据发送错误时的错误恢复过程。
STA1和STA2、3进行上行多用户发送给AP，其中STA1的数据发送错误，STA2、STA3的数据发送正确。此时AP不发送反馈帧，等待STA1自动进行重传恢复，STA1在发送完成后，没有收到AP的正确反馈，则STA1等待错误恢复时间Δt，若此时间内判断信道为空闲，则Δt后进行重传恢复。
若在Δt时间内，STA1检测到了AP针对自己的错误指示，则STA1可以在收到错误指示后进行错误恢复。
所述Δt时间为协议预定义的时间，是指当发送站点发送错误后进行重传恢复的时间，具体的可以为点协调帧间间隔，point(coordination function)interframe space，简称PIFS时间；或者PIFS时间加上等待应答超时时间，所述等待应答超时时间等于PIFS时间加上接收开始延迟时间。
AP收到STA1的重传恢复帧，可以在发送的MU-BA帧中对STA2和STA3的上一次发送的数据帧进行确认。共享次节点在持有方节点的TXOP内，不能自行进行错误恢复或发送，只有当收到AP的指示后才可以发送上行帧。
实施例七
图17是根据本发明可选实施例的所有节点数据发送错误的恢复过程示意图，如图17所示，站点STA1竞争到TXOP，共享进行上行多用户传输时，持有方节点的数据发送错误时的错误恢复过程。
STA1和STA2、3进行上行多用户发送给AP，所有节点的的数据发送错误。此时AP不发送反馈帧，等待STA1自动进行重传恢复，STA1在发送完成后，没有收到AP的正确反馈，则STA1等待错误恢复时间Δt，若此时间内判断信道为空闲，则Δt后进行重传恢复。
AP收到STA1的重传恢复帧，可以在发送的MU-BA帧中对STA2和STA3的上一次发送的数据帧进行确认。共享次节点在持有方节点的TXOP内，不能自行进行错误恢复或发送，只有当收到AP的指示后才可以发送上行帧。
实施例八
本实施例说明携带上行多用户共享信息的无线帧及主节点发送的反馈帧的示例。
携带上行多用户共享信息的无线帧可以是持有方节点发送的数据帧，主节点发送的反馈帧帧类型可以是块应答帧。如实施例2-7所述。
图18是根据本发明可选实施例的携带多用户共享信息的无线帧及其反馈帧的示意图；图19是根据本发明可选实施例的携带多用户共享信息的无线帧及其反馈帧的示意图，如图18，图19所示，携带上行多用户共享信息的无线帧也可以是STA1发送的特殊RTS帧，或者其他控制/管理帧。主节点发送的反馈帧可以是一个或多个串行或并 行发送的无线帧，帧类型可以是CTS帧，或者其他控制/管理帧，或者上述帧的组合形式。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
