When the transmission collides, the CW is increased exponentially, and the final value does not exceed CWmax. When the transmission is successful, the CW value is reset to CWmin.

Description

竞争传输方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种竞争传输方法及装置。
背景技术
目前，随着更多的人使用无线局域网(Wireless Local，简称为WLAN)进行数据通信，WLAN网络负载也在不断加重，且随着用户数目的增多，WLAN网络的效率会出现明显下降的趋势，单纯提高速率并不能解决该问题，多用户并行传输作为解决网络效率的一种备选技术，引起了广泛关注和研究。现有技术中，多用户并行传输技术包括多用户多入多出(multi-user Multiple Input Multiple Output，简称为MU-MIMO)技术(空域多址)，正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)技术(频域多址)等。
WLAN中，一个接入站点(access point，简称为AP)以及与该AP相关联的多个非接入站点(non-AP Station，简称为non-AP STA)组成了一个基本服务集(basic service set，简称为BSS)，如图1所示。WLAN中的多用户并行传输一般为多个non-AP STA同时向AP发送数据，一般称这种为上行多用户(uplink multi-user，简称为UL MU)传输，或者AP同时给多个non-AP STA发送数据，称之为下行多用户(downlink multi-user，简称为DL MU)传输，典型的上下行多用户传输帧交换序列如图2所示。
现有方案中，UL MU传输需要AP进行触发，例如AP可以发送触发帧来触发，或者AP采用在无线帧中携带触发信息域的无线帧的方式触发。触发帧或者携带触发信息域的无线帧中携带了站点的调度信息，如站点的标识信息、站点进行上行传输所使用的时间和频率资源信息、站点的时频偏校准信息、站点上行传输的数据包长度等。AP发送触发帧或携带触发信息域的无线帧之后，站点接收触发帧或携带触发信息域的无线帧，如果自己的标识信息携带在其中，则表示自己被调度在本次UL MU传输中，若自己有待发送数据，则进行准备，并按照AP所指示的时频偏校准信息进行同步，在所分配的时间和频率资源上进行发送。
现有技术中，具有服务质量(Quality of Service，简称为QoS)的WLAN系统的数据发送方式分为竞争发送和非竞争发送。其中，竞争发送机制是指增强型分布信道接入机制(enhanced distributed channel access，简称为EDCA)，即业务流数据具有优先级属性，业务流的每个数据包都根据其优先级映射到4个接入类别(Access Category，简称为AC)队列中的某一个队列中排队等待传输。每个AC都具有一组竞争参数，竞争参数包括帧间间隔(arbitration interframe space，简称为AIFS)、占用信道传输机会的最大时长，竞争窗口的最大值(Contention Window max，简称为CWmax)和最小值CWmin。不同的AC的竞争参数取值不同，从而体现了AC的优先级。非竞争发送机制是指混合控制信道接入(HCF controlled channel access，简称为HCCA)，使用非竞争发送机制发送的业务流的数据包，不主动竞争信道，而是当站点收到AP发送的轮询帧后，将数据包发送给AP。
4个AC进行竞争发送，具体来说竞争的过程是，对于每个AC，站点都将CW窗的初始值设置为CWmin，并在[0,CWmin]中随机选择一个整数，用该值设置回退计时器Backoff timer。站点监听信道，当信道空闲满足该AC的帧间间隔AIFS时长时，站点进行随机回退，每听到一个时隙空闲，则Backoff timer减一，当Backoff timer减到0，该AC获得传输机会，并发送数据。当传输发生碰撞，CW要以指数增加，并且最终值不超过CWmax，当传输成功，CW值重置为CWmin。控制帧和管理帧并非数据帧，现有技术中常常规定控制帧和管理帧采用特定的AC进行发送。
现有技术中，触发帧可以采用预定发送时刻的方式发送，或者采用竞争的方式进行发送，例如，可以令站点上报自己各AC的缓存队列长度，AP侧获得站点侧的AC队列的缓存数据长度后，上行AC队列在AP侧也参与竞争，如果上行某个AC竞争成功，则发送该AC队列的触发帧，触发UL MU传输。
然而，采用竞争方式发送触发帧后，站点按照触发帧的指示进行了UL MU传输，站点侧和AP侧的上行AC队列的CW取值和Backoff timer应该如何处理，相关技术并没有给出解决方案。
针对相关技术中，采用竞争方式发送触发帧后，站点侧和AP侧的上行AC队列的CW取值和Backoff timer应该如何处理的问题，还未提出有效的解决方案。

需要说明的是，上述各个模块是可以通过软件或硬件来实现的，对于后者，可以通过以下方式实现，但不限于此：上述各个模块均位于同一处理器中；或者，上述各个模块分别位于第一处理器、第二处理器和第三处理器…中。
针对相关技术中存在的上述问题，下面结合具体的可选实施例进行说明。
实施例一
AP和STA建立的业务流的数据发送方式有两种，非竞争方式发送和竞争方式发送。对于竞争方式发送，数据进入AC队列排队等待竞争发送。图13是根据本发明实施例的AP为站点建立上行AC队列示例图之一，如图13所示，AP侧收集与其关联的一个或多个STA上报 的自己的四个AC队列的缓存队列长度信息，AC优先级顺序由低到高依次是AC-BK(background)，AC-BE(best effort)，AC-VI(video)，AC-VO(voice)。AP侧建立四个上行AC队列，各STA属于相同AC队列的数据进入同一队列排队等待发送。四个AC队列与AP本身的四个下行AC队列同时进行竞争。对于非竞争方式发送的业务流，STA也可以上报非竞争方式发送的一个或多个业务流的缓存队列长度给AP。
上行AC之一，例如是AC-VO竞争成功，则AP发送触发帧或携带触发信息域的帧。AP在触发帧或触发信息域内调度STA1～STA4进行上行多用户数据传输，AP在触发帧内指定STA1～STA4所发送的数据是AC-VO队列的数据。
STA1～STA4收到触发帧，根据触发帧内的调度信息和时频偏校准信息进行上行多用户传输。AP指定了发送的数据是AC-VO队列的数据，则STA1～STA4均需发送AC-VO队列的数据。
AP也可以分别指示每个STA所发送的数据的AC队列，例如指示STA1发送AC-VO，STA2和STA3发送AC-BE，STA4发送AC-VI。则收到触发帧后，STA1发送AC-VO队列的数据，STA2和STA3发送AC-BE队列的数据，STA4发送AC-VI队列的数据。
AP收到上行多用户数据，成功完成校验和解调，则将AP侧的上行AC-VO队列的竞争窗口重置为初始值CWmin。
AP对收到的上行多用户数据发送确认帧给站点，站点收到确认帧，则将自己的AC-VO队列的竞争窗口重置为初始值CWmin，将AC-VO队列的回退计时器清零。
AP收到STA1～STA4发送的数据，AP根据数据包数量调整自己这一侧的上行AC-VO缓存队列长度参数；如果STA1～STA4在上行数据中携带了当前自己一个或多个接入类别缓存队列长度，则AP根据站点提供的信息将AP侧相应的上行AC的缓存队列长度参数更新。
实施例二
AP侧收集与其关联的一个或多个STA上报的自己的四个AC队列的缓存队列长度信息，四个队列分别是AC-BK(background)，AC-BE(best effort)，AC-VI(video)，AC-VO(voice)。AP侧建立四个上行AC队列，各STA属于相同AC队列的数据进入同一队列排队等待发送。四个AC队列与AP本身的四个下行AC队列同时进行竞争。
上行AC-VO竞争成功，则AP发送触发帧或携带触发信息域的无线帧。AP在触发帧内调度STA1～STA4进行上行多用户数据传输，AP在触发帧内指定STA1～STA4所发送的数据是AC-VO队列的数据。
STA1～STA4收到触发帧，根据触发帧内的调度信息和时频偏校准信息进行上行多用户传输。AP指定了发送的数据是AC-VO队列的数据，STA1～STA4可以发送任意AC队列的数据，且保证至少包括AC-VO队列的数据。
AP也可以分别指示每个STA所发送的数据的AC队列，例如指示STA1发送AC-VO， STA2发送AC-BE，STA3和STA4发送AC-VI。则收到触发帧后，STA1至少发送AC-VO队列的数据，STA2至少发送AC-BE队列的数据，STA3和STA4至少发送AC-VI队列的数据。除上述指定AC队列的数据外，各STA还可以发送其他任意AC队列的数据。
AP收到上行多用户数据，成功完成校验和解调，则将AP侧的上行AC-VO队列的竞争窗口重置为初始值CWmin。
AP对收到的上行多用户数据发送确认帧给站点，站点收到确认帧，则将自己所传输的数据对应的AC队列的竞争窗口重置为初始值CWmin，将AC队列的回退计时器清零。
AP收到STA1～STA4发送的数据，AP调整自己这一侧的上行AC-VO缓存队列长度参数以及其他收到的数据对应的上行AC的缓存队列长度参数；如果STA1～STA4在上行数据中携带当前自己一个或多个接入类别缓存队列长度，则AP根据站点提供的信息将AP侧相应的上行AC的缓存队列长度参数更新。
实施例三
AP侧收集与其关联的一个或多个STA上报的自己的四个AC队列的缓存队列长度信息，四个队列分别是AC-BK(background)，AC-BE(best effort)，AC-VI(video)，AC-VO(voice)。AP侧建立四个上行AC队列，各STA属于相同AC队列的数据进入同一队列排队等待发送。四个AC队列与AP本身的四个下行AC队列同时进行竞争。
上行AC之一，例如是AC-VO竞争成功，则AP按照AC-VO的竞争参数进行触发帧的发送。
AP在触发帧内调度STA1～STA4进行上行多用户数据传输，AP在触发帧内不指定STA1～STA4所发送的数据的AC。
STA1～STA4收到触发帧，根据触发帧内的调度信息和时频偏校准信息进行上行多用户传输。由于AP没有指定发送的AC队列，STA1～STA4可以在A-MPDU中发送任意AC队列的数据。
或者，AP在触发帧内指定STA1～STA4所发送的数据的AC是AC-VO，但STA1～STA4收到触发帧，可以在A-MPDU中发送任意AC队列的数据。
或者，AP可以分别指示每个STA所发送的数据的AC队列，例如指示STA1发送AC-VO，STA2发送AC-BE，STA3和STA4发送AC-VI，但收到触发帧后，各STA发送任意AC队列的数据。
AP收到上行多用户数据，成功完成校验和解调，则将相应的AP侧的上行AC队列的竞争窗口重置为初始值CWmin。
AP对收到的上行多用户数据发送确认帧给站点，站点收到确认帧，则将自己所传输的数据对应的AC队列的竞争窗口重置为初始值CWmin，将AC队列的回退计时器清零。
AP收到STA1～STA4发送的数据，AP调整自己这一侧的收到的数据对应的上行AC的缓存队列长度参数；如果STA1～STA4在上行数据中携带当前自己一个或多个接入类别缓存队列长度，则AP根据站点提供的信息将AP侧相应的上行AC的缓存队列长度参数更新。
实施例四
AP侧收集与其关联的一个或多个STA上报的自己的四个AC队列的缓存队列长度信息，AP侧建立四个上行AC队列，四个AC队列与AP本身的四个下行AC队列同时进行竞争。
上行AC之一，例如是AC-BE竞争成功，则AP发送触发帧或携带触发信息域的帧。AP在触发帧或携带触发信息域的无线帧内调度STA1～STA4进行上行多用户数据传输，AP在触发帧内指示允许接入的AC是AC-BE。
STA1～STA4收到触发帧后，允许发送AC优先级等于或者高于AC-BE的队列的数据，即STA1～STA4可以发送AC-BE，AC-VI和AC-VO队列的数据。
AP也可以分别指示每个STA所发送的数据的AC队列，例如指示STA1发送AC-VO，STA2发送AC-BE，STA3和STA4发送AC-VI。则收到触发帧后，STA1允许发送AC-VO队列的数据，STA2允许发送AC-BE，AC-VI和AC-VO队列的数据，STA3和STA4允许发送AC-VI和AC-VO队列的数据。
AP收到上行多用户数据，成功完成校验和解调，则将AP侧的上行AC-BE队列的竞争窗口重置为初始值CWmin。
AP对收到的上行多用户数据发送确认帧给站点，站点收到确认帧，则将自己所传输的数据对应的AC队列的竞争窗口重置为初始值CWmin，将AC队列的回退计时器清零。
AP收到STA1～STA4发送的数据，AP根据数据包数量调整自己这一侧的上行AC缓存队列长度参数；如果STA1～STA4在上行数据中携带了当前自己一个或多个接入类别缓存队列长度，则AP根据站点提供的信息将AP侧相应的上行AC的缓存队列长度参数更新。
实施例五
图14是根据本发明实施例的AP为站点建立上行AC队列示例图之二，如图14所示，AP侧仅建立一个上行队列，各STA的所有AC的数据全部进入该队列等待竞争发送。此上行队列具有系统预先配置的竞争参数，当竞争成功，AP发送触发帧，触发上行多用户传输。
STA1～STA4收到触发帧，根据触发帧内的调度信息和时频偏校准信息进行上行多用户传输。AP指定STA1～STA4的当前上行多用户传输的AC是AC-VO，或者为每个站点分别指定了上行多用户传输的AC，站点被指定发送的AC队列中没有缓存数据，则可以发送其他AC队列中的缓存数据，如果站点的四个AC的缓存队列中都没有待发送数据时，站点可以发送采用非竞争方式进行发送的业务流的数据。
站点进行上行数据传输，AP收到站点发送的上行数据，成功完成校验和解调，则将相应的AP侧的上行AC队列的竞争窗口重置为初始值CWmin。
AP收到STA1～STA4发送的数据，如果STA1～STA4在上行数据中携带当前自己一个或多个接入类别缓存队列长度，则AP根据站点提供的信息将AP侧相应的上行AC的缓存队列长度参数更新。
实施例六
AP在系统信息中指示一个或多个触发帧或者含有触发信息域的无线帧的发送时刻，在预定时刻到达时发送触发帧或含有触发信息域的无线帧。
AP收集STA上报的非竞争方式发送的业务流的缓存队列长度。AP在触发帧或携带触发信息域的无线帧中指定站点进行上行多用户传输的数据是采用非竞争方式进行发送的业务流的数据。此时，在触发帧或携带触发信息域的无线帧中携带的不是AC标识，而是采用非竞争方式进行发送的业务流的标识。
站点收到触发帧或携带触发信息域的无线帧，则发送采用非竞争方式进行发送的业务流的数据。如果站点此时没有采用非竞争方式进行发送的业务流的数据，则站点可以发送任意AC队列的数据。
实施例七
AP在系统信息中指示一个或多个触发帧或者含有触发信息域的无线帧的发送时刻，在预定时刻到达时发送触发帧或含有触发信息域的无线帧。站点在预定时刻没有收到接收AP发送的触发帧或携带触发信息域的无线帧，站点可以使用任意接入类别竞争到的发送机会发送采用非竞争方式进行发送的业务流的数据。
实施例八
AP侧收集与其关联的一个或多个STA上报的自己的四个AC队列的缓存队列长度信息，四个队列分别是AC-BK(background)，AC-BE(best effort)，AC-VI(video)，AC-VO(voice)。AP侧建立四个上行AC队列，各STA属于相同AC队列的数据进入同一队列排队等待发送。四个AC队列与AP本身的四个下行AC队列同时进行竞争。或者，AP侧建立一个上行AC队列，所有STA的所有AC队列的数据都进入该队列等待竞争发送。
上行AC竞争成功，AP发送触发帧或者带有触发信息域的帧，触发STA1～STA4进行上行多用户传输，AP在触发帧或者携带触发信息域的无线帧中指示STA1～STA4发送AC-VI的数据，则上述站点发送AC-VI的数据，或者，可以发送AC-VI和优先级高于AC-VI的AC，即AC-VO的数据。且在上述两种发送情况下，默认总可以发送采用非竞争方式进行发送的业务流的数据。可以将采用非竞争方式进行发送的业务流看作最高优先级，在任何情况下总可以进行发送。
AP也可以分别指示每个STA所发送的数据的AC队列，例如指示STA1发送AC-VO，STA2发送AC-BE，STA3和STA4发送AC-VI。则收到触发帧后，STA1发送AC-VO队列的数据，STA2和STA3发送AC-BE队列的数据或者优先级高于AC-BE的数据，STA4发送AC-VI 队列的数据，或者优先级高于AC-VI的数据。且在上述发送情况下，各站点还可以发送采用非竞争方式进行发送的业务流的数据。
站点进行上行数据传输，AP收到站点发送的上行数据，成功完成校验和解调，则将相应的AP侧的上行AC队列的竞争窗口重置为初始值CWmin。
AP收到STA1～STA4发送的数据，根据收到的数据包数量情况将相应的上行AC以及上行非竞争方式发送的业务流的缓存队列长度参数进行更新。如果STA1～STA4在上行数据中携带当前自己一个或多个接入类别缓存队列长度，以及非竞争方式发送的业务流的缓存队列长度参数，则AP根据站点提供的信息将AP侧相应的上行AC的缓存队列长度参数更新。
实施例九
AP发送触发帧或者带有触发信息域的帧，触发STA1～STA4进行上行多用户传输，AP在触发帧或者携带触发信息域的无线帧中指示STA1～STA4发送AC-VI的数据，则上述站点发送AC-VI的数据，或者，可以发送AC-VI和优先级高于AC-VI的AC，即AC-VO的数据。且在上述两种发送情况下，站点还应至少发送采用非竞争方式进行发送的业务流的数据(该队列没有待传输数据时可以不发)。
AP也可以分别指示每个STA所发送的数据的AC队列，例如指示STA1发送AC-VO，STA2发送AC-BE，STA3和STA4发送AC-VI。则收到触发帧后，STA1发送AC-VO队列的数据，STA2和STA3发送AC-BE队列的数据或者优先级高于AC-BE的数据，STA4发送AC-VI队列的数据，或者优先级高于AC-VI的数据。且在上述发送情况下，各站点至少发送采用非竞争方式进行发送的业务流的数据。
站点进行上行数据传输，AP收到站点发送的上行数据，成功完成校验和解调，则将相应的AP侧的上行AC队列的竞争窗口重置为初始值CWmin。
AP收到STA1～STA4发送的数据，根据收到的数据包数量情况将相应的上行AC以及上行非竞争方式发送的业务流的缓存队列长度参数进行更新。如果STA1～STA4在上行数据中携带当前自己一个或多个接入类别缓存队列长度，以及非竞争方式发送的业务流的缓存队列长度参数，则AP根据站点提供的信息将AP侧相应的上行AC的缓存队列长度参数更新。
实施例十
AP发送触发帧或者带有触发信息域的帧，触发STA1～STA4进行上行多用户传输，AP在触发帧或者携带触发信息域的无线帧中指示STA1～STA4发送AC-VI的数据，则上述站点优先发送AC-VI的数据，如果将AC-VI队列缓存的数据全部打包进MAC层协议数据单元后，还未达到AP指定的上行传输的数据包的包长，站点可以继续将其他AC队列的数据打包进入当前MAC层协议数据单元，或者将采用非竞争方式进行发送的业务流的数据打包进入当前MAC层协议数据单元。
AP也可以分别指示每个STA所发送的数据的AC队列，例如指示STA1发送AC-VO， STA2发送AC-BE，STA3和STA4发送AC-VI。则收到触发帧后，STA1优先发送AC-VO队列的数据，STA2和STA3优先发送AC-BE队列的数据，STA4优先发送AC-VI队列的数据。如果优先AC队列缓存的数据全部打包进MAC层协议数据单元后，还未达到AP指定的上行传输的数据包的包长，站点可以继续将其他AC队列的数据打包进入当前MAC层协议数据单元，或者将采用非竞争方式进行发送的业务流的数据打包进入当前MAC层协议数据单元。
站点进行上行数据传输，AP收到站点发送的上行数据，成功完成校验和解调，则将相应的AP侧的上行AC队列的竞争窗口重置为初始值CWmin。
AP收到STA1～STA4发送的数据，根据收到的数据包数量情况将相应的上行AC以及上行非竞争方式发送的业务流的缓存队列长度参数进行更新。如果STA1～STA4在上行数据中携带当前自己一个或多个接入类别缓存队列长度，以及非竞争方式发送的业务流的缓存队列长度参数，则AP根据站点提供的信息将AP侧相应的上行AC的缓存队列长度参数更新。
综上所述，通过本发明，能够使得在进行由AP触发的上行多用户传输时站点侧的竞争参数根据数据发送状态及时进行调整，从而反映信道的忙闲状态，并且使得站点侧与AP侧的站点的同一队列的竞争参数能够保持同步，为整个网络的站点之间的竞争提供了较好的公平性。
