Description

本申请涉及通信技术,尤其涉及一种通信方法、设备及系统。
随着无线通信业务的飞速发展,通信网络中可能出现长距离传输,为保证通信的稳定性,可在长距离传输的节点之间增加一个或多个中继节点,形成包含中继节点的传输网络。中继节点在传输网络中工作时,由中继节点(Relay)接收上层中继节点或根接入点(Root Access Point,简称Root AP)发送的数据,并将该数据转发给下层Relay或站点(Station,简称STA)。
上述数据传输过程时,发出数据的上层节点均需进行信道竞争,当成功竞争信道后将数据发出,为提高传输效率,现有的中继通信方法中,引入了传输机会(Transmit Opportunity,简称TXOP)共享机制,Root AP将数据传输给Relay后,通过指示可使Relay继续使用Root AP竞争到的TXOP,将数据转发给下层STA,从而降低了部分数据延迟。但是上述中继通信方法仅适用于单用户数据通信的情况,当存在多用户均需收发数据的情况时,TXOP共享机制仅能用于一个数据传输过程中,无法使多用户同时使用TXOP,需为每一用户在不同时刻分别发送数据,数据传输效率仍然较低。

本申请实施例提供一种通信方法、设备及系统,用于解决当通信系统中存在根据接收到的传输机会共享指示进行数据发送时,多个用户无法同时使用TXOP,导致数据传输效率仍然较低的问题。
中继通信的系统架构中共有3类节点:根接入点(Root Access Point,简称Root AP),中继(Relay),以及站点(Station,简称STA)。上述各节点具体可以为服务器、基站、工作站、计算机、网关、手机、笔记本电脑等设备。当两个节点之间距离较长时,在两个节点之间增加Relay节点,可用于实现将上级站点节点发送的数据转发给下级站点节点,确保数据传输的稳定性,其中Relay的上级站点节点即为根接入点,Relay的下级站点节点即为普通站点。示例性的,STA可直接关联在Root AP上,也可关联在Relay上。可选的,Relay可以关联在Root AP上;也可以关联在Relay上,组成一个多级中继,在多级Relay结构中,一个Relay的上级Relay其作用相当于一个Root AP,一个Relay的下级Relay,其作用相当于一个STA。一个Root AP的下级可以关联多个Relay和多个STA,一个Relay的下级可以关联多个STA。
下面结合采用具体的实施例,对本申请实施例提供的通信方法进行详细说明。
图1为应用本申请实施例提供的通信方法的系统架构示意图。如图1所示,中继通信的系统架构包括:一个根接入点Root AP,三个中继Relay(Relay1、Relay3和Relay7)和6个站点STA(STA2、STA4、STA5、STA6、STA8和STA9);其中,Relay1、STA2、Relay3直接与Root AP关联,作为Root AP的下一级;STA4和STA5直接与Relay1关联,作为Relay1的下一级;STA6和Relay7直接与Relay3关联,作为Relay3的下一级;STA8和STA9直接与Relay7关联,作为Relay7的下一级。以上系统架构仅为用于说明本申请实施例而提供的一种系统架构的实现方式,而并非对本申请实施例提供的通信方法的应用场景的限制。
其中,Relay内部包含3个部分:中继站点(relay STA)、中继功能(relay function)和中继接入点(relay AP)。中继功能代表中继内部用于实现中继功能的模块。图2为应用本申请实施例提供的通信方法的中继设备的结构示意图。如图2所示,其中relay STA作为上层基本服务集合(Basic Service Set,简称BSS)中的节点,同Root AP或者上一层Relay进行传输通信,而relay AP作为下层BSS的节点,
同与其关联的Relay或者STA进行传输通信。relay function的作用是relay STA和relay AP的桥梁,并且与逻辑链路层相连,进行Relay功能的实现。在现有技术中,当由Root AP直接将数据包发送给距离较远的STA时,可先由Root AP将数据包发送给Relay,Relay内部的relay STA接收该数据包,并将该数据包通过relay function转发给relay AP,再由relay AP将数据包发送给STA,以提高数据包传输的稳定性。
下面在上述系统架构的基础上,以具体地实施例对本申请的技术方案以及本申请的技术方案如何实现进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。
一方面,Relay用于实现将Root AP发送的数据转发给STA。
图3为本申请实施例提供的通信方法实施例一的信令流程图。图4为图3所示实施例一的数据传输示意图。如图3和图4所示,本方法包括:
S301、发送第一数据包;
具体的,第一设备发送第一数据包,第一数据包包括传输机会共享指示信息、少一个第一数据以及各第一数据的接收地址和目的地址,传输机会共享指示信息用于指示接收地址对应的设备在第一设备的传输机会内进行数据传输。中继设备接收第一设备发送的第一数据包。
S302、发送第二数据包;
具体的,中继设备根据传输机会共享指示信息,发送第二数据包,其中,第二数据包包括至少一个第一数据,以及各第一数据的目的地址,第二数据包的格式为多用户格式。目的地址对应的设备接收第二数据包。
在图3和图4中,以Root AP为第一设备,STA为目的设备,Relay接收来自Root AP的第一数据包,并将第二数据包转发给两个STA为例进行说明。图4中示出各设备发出的数据。
具体的,在S301中,第一设备发送第一数据包,Relay接收第一设备发送的第一数据包。其中,第一设备可以为Root AP或STA。当第一设备为Root AP时,第一数据包为下行数据帧,第一数据包中的传输机会共享指示信息为Root AP竞争到的信道的信息;当第一设备为STA时,第一数据包为上行数据帧,第一数据包中的传输机会共享指示信息为STA竞争到的信道的信息。第一设备通过信道竞争,竞争得到数据传输机会,为使数据能够较快的转发给目的设备,第一设备将自身竞争到的传输机会分享给Relay,从而使得Relay可根据共享的传输机会,直接进行数据传输。第一数据包还包括至少一个第一数据,以及各第一数据的接收地址和目的地址,第一数据即为希望中继设备转发的数据,接收地址为负责转发第一数据的设备,即Relay,目的地址即为最终接收第一数据的设备,即STA。
可选的,在Relay接收第一数据包之前,Relay判断第一数据包中的接收地址中是否存在Relay的标识,若有,则接收,若没有则说明第一数据包中没有需要Relay转发的数据,也可判断第一数据包中的目的地址中是否包括Relay的标识,若没有则说明没有发送给Relay的数据。
可选的,Relay的标识可以采用Relay STA在所在BSS的关联标识(Association Identifier,简称AID),AP会为BSS内的各设备分配各自的关联标识。可选的,AID可根据各设备的身份标识、媒体接入控制(Media Access Control,简称MAC)地址、IP地址等生成。
具体的,在S302中,Relay根据第一设备竞争到的传输机会,发送第二数据包。其中第二数据包中包括第一数据包中读取的第一数据以及第一数据的目的地址,由于第一数据的目的地址为多个,若逐个发送,数据传输效率依然较低。为提高数据传输效率,将第二数据包的格式设置为多用户格式(Multiple User Format,简称MU format)。多用户格式的数据包如下所示。
多用户格式的数据包包含传统前导码、高效前导码,和承载着MAC帧的数据字段,传统前导码包括传统短训练字段(Legacy Short Training Field,简称L-STF),传统长训练字段(Legacy Long Training Field,简称L-LTF)和传统信令字段(Legacy Signal Field,简称L-SIG)。传统前导码用来保证数据包的兼容性,使得以前版本标准的STA也可以读懂传统前导码部分。多用户格式的数据包还包括传统信令字段的重复(Repeated L-SIG)、高效信令字段A、高效信令字段B、高效短训练序列和高效长训练序列。其中,Repeated L-SIG通过重复特性,用于进行自动检测以及对L-SIG鲁棒性的增强;高效信令字段A(High Efficient Signal Field A,简称HE-SIG-A),用来承载基本服务集颜色(Basic Service Set Color,简称BSS Color)、空间复用参数、传输机会时长(Transmit Opportunity Duration,简称TXOP Duration)等信令信息。高效信令字段B(High Efficient Signal Field B,简称HE-SIG-B),用来承载本BSS内多个STA的资源调度信息。高效短训练序列(High Efficient Short Training Field,简称HE-STF)和高效长训练序列(High Efficient Long Training Field,简称HE-LTF),分别用来进行多输入多输出(Multiple Input Multiple Output,简称MIMO)的自动增益控制(Automatic Gain Control,简称AGC)和信道测量。其中HE-LTF字段可能包含多个HE-LTF符号,用来进行多个空时流上的信道测量。最后是数据Data部分,用来承载MAC帧。
可选的,本申请实施例中的多用户格式存在正交频分多址(Orthogonal Frequency Division Multiple Access,简称OFDMA)和多用户输入输出(Multiple User Multiple Input Multiple Ouput,简称MU-MIMO)两种不同的多用户传输形式,以及两者的混合。在OFDMA传输中,对于某一个STA,其HE-STF,HE-LTF和Data会处在整个带宽内的某一个子带中,并根据资源调度信息的不同,以不同的格式分布在不同的位置。对于MU-MIMO,其HE-STF,HE-LTF和Data会处在多个空间流中的一部分空间流中,同样根据资源调度信息的不同,以不同的格式分布在不同的位置。
通过将第二数据包以多用户的形式打包,并将第二数据包发送出去,系统架构中的各设备可帧听第二数据包,检测第二数据包中是否包含自己的AID,当包含则接收第二数据包中与自己AID对应的数据部分,当不包含,则不接收。从而使得多个用户可同时接收到数据,实现了多用户的数据的同时发送和接收,提高了传输效率。图3和图4中示例性的以两个第一数据的目的地址为例,对本申请实施例进行说明,而并非对本申请实施例中的待转发数据的目的设备的数目的限制。当第一数据数量越多,本申请实施例提高传输效率的效果越明显。
本申请实施例提供的通信方法,通过接收传输机会共享指示信息,根据传输机会共享指示信息,将需要转发给多个设备的第一数据以多用户格式进行转发,实现了多用户的数据的同时发送和接收,提高了中继通信系统中的数据传输效率。
可选的,各设备为确认发出的数据包被目的设备正常接收,在发送数据包的同时,还可同时发送确认请求信息,向目的设备索取确认帧,或将确认请求信息集成在数据包中,当接收到目的设备发送的确认帧时,则确认发出的数据包被正常接收。
进一步的,在上述实施例的基础上,第二数据包还包括至少一个第二数据,以及各第二数据的目的地址。
示例性的,中继设备在接收到第一数据,向第一数据的目的地址对应的目的设备,即图4中的STA4和STA5,进行数据转发时,还可在第二数据包中增加其他数据,记为第二数据,第二数据的目的地址可以为第一设备,还可以为其他与Relay关联的STA,例如,可在图1所示系统架构中,在中继1的下级增加一个站点10,站点10与站点4、站点5并列。图5为本申请实施例提供的通信方法实施例二的数据传输示意图。如图5所示,Relay发送的第二数据包中包括第二数据和从Root AP发送的第一数据包中接收到的第一数据,Relay利用多用户格式,可同时实现第一数据和第二数据的发送。可选的,Relay也可采用单用户传输格式单独发送第二数据。
当将第二数据放入第二数据包中发送给Relay的上级设备Root AP时,需在第二数据包中设置Root AP的标识。可选的,Relay在同Root AP关联或者交互Relay功能信息时,向Root AP分配AID。则当Relay发送多用户格式的第二数据包时,若Root AP在第二数据包的HE-SIG-B中读取到了自己的AID,则进行数据的接收。可选的,将一个预留的或者称作特殊的固定的AID作为Relay进行下行多用户传输时Root AP的AID。则当Relay发送多用户格式的第二数据包时,若Root AP在第二数据包的HE-SIG-B中读取到了该预留AID,则进行数据的接收。
可选的,考虑到现有的节能机制,Root AP正常情况下所接收的数据都是上行数据,若Root AP收到下行数据包,则可以选择进行休眠,直到该数据包结束。在应用本申请实施例提供的通信方法时,Root AP有接收多用户下行传输数据的可能,因此若Root AP收到下行数据包,则需要确认是否有自己的AID,若有自己的AID,则不休眠。
可选的,在上述任一实施例中,当第一设备为STA,例如为图1中的STA4,Relay用于将STA4发送的数据包转发给Root AP,或者同时转发给Root AP与STA5,仍可应用本申请实施例提供的通信方法,本申请对此不再赘述。以下各实施例中均仅以Relay转发来自Root AP的数据包为例。
进一步的,在上述任一实施例的基础上,第一数据包中还包括如下中的至少一项:共享传输节点集、共享传输帧类型集、共享传输业务类型集。S302中的发送第二数据包,具体包括:
根据共享传输设备集、共享传输帧类型集、共享传输业务类型集中的至少一项,以及传输机会共享指示信息,生成并发送第二数据包。
其中,共享传输节点集中包括至少一个设备的标识,指示允许根据传输机会共享指示信息向共享传输设备集中的设备进行数据传输;
共享传输帧类型集,表示允许根据传输机会共享指示信息传输的帧类型的集合;
共享传输业务类型集,表示允许根据传输机会共享指示传输的业务类型的集合。
示例性的,现有的TXOP共享机制控制Relay仅用于转发Root AP发来的数据包,也就是需要Relay转发的数据包。本申请实施例中,通过在第一数据包中携带共享传输帧类型集,指示允许Relay转发的帧的类型,使得Relay可根据需求在第二数据包携带除第一数据以外的其他数据,例如图5中所示的第二据帧。示例性的,第二数据帧可以为Relay向Root AP发送确认帧或其他上行帧,Relay向Relay进行站点到站点(Device to Device,简称D2D)的传输或者发送relay AP所在BSS的管理帧。
示例性的,共享传输帧类型集可利用比特位图表示,每一个比特代表一个帧类别,若置1,则表示在共享TXOP时,允许传输该类别的帧,若置0,则不允许传该类别的帧,帧类别包括但不限于以下几种:
1、向目的STA发送除转发数据以外的其他数据;
2、向其他STA(非待转发数据的目的设备)发送数据;
3、向其他STA(非待转发数据信息的目的设备)发送触发帧索取数据;
4、向Root AP发送除确认帧以外的其他帧;
5、向Root AP发送触发帧,触发除确认帧以外的其他帧。
示例性的,STA在将TXOP共享给Relay时,也可以指示Relay允许采用TXOP共享机制传输的帧类别,其包括但不限于:
1、向自己发送除确认帧以外的其他帧;
2、向其他STA发送数据;
3、向其他STA发送触发帧,触发其进行传输;
4、向Root AP发送除待转发数据的其他数据。
可选的,还可在第一数据包中携带共享传输节点集。Root AP在共享TXOP时,也可以以携带共享传输节点集的方式,对多个目的STA分别指示,指示Relay允许使用共享TXOP给哪几个STA转发数据。
可选的,还可在第一数据包中携带共享传输业务类型集。业务类型包括语音(Voice),视频(Video),尽力(Best Effort)等。其中有些业务对延迟很敏感,比如Voice,而有些业务对延迟不是很敏感,比如Best Effort。因此,可以针对不同的业务分别指示是否允许Relay使用TXOP共享机制来转发数据给目的STA/Root AP。
通过限制Relay允许传输的帧类别、目的STA以及业务类型,有助于TXOP的授予者,即第一设备,更好的掌控TXOP的使用方式,使得更需要传输的数据类别得以传输,降低时延敏感业务的时延。
进一步的,在上述任一实施例的基础上,传输机会共享指示信息包括信道信息和/或有效时长信息;S302中的发送第二数据包,具体包括:
根据信道信息和/或所述有效时长信息,发送第二数据包。
示例性的,在上述各实施例中,第一设备将获得的TXOP在全部带宽范围内授予给Relay,Relay可以在全部或者部分带宽上传输数据,当完成转发数据和获得确认帧的交互之后,则结束TXOP。
可选的,为提高信道利用率,可以在给Relay发送数据包时,指示Relay可以允许使用的信道/资源块,而其他的信道/资源块,Root AP可以继续利用。图6为本申请实施例提供的通信方法实施例三的数据传输示意图。如图6所示,Root AP在发送第一数据包时,采用多用户格式同时发送数据给Relay1以及和Relay1同级的STA2和Relay3,并在第一数据包中指示允许Relay1使用信道2,而Root AP会继续使用信道1。则从图6中可以看出,Relay1采用信道2发送第二数据包,转发数据给STA4和STA5;与此同时STA2和Relay3利用信道1向Root AP发送确认帧。
可选的,除了在频域上指示Relay可以采用的信道/资源块,第一设备在指示TXOP共享时,也可以同时指示Relay允许使用共享TXOP的时间,在该时间之后,Root AP继续使用该TXOP。同样如图6所示,Root AP指示Relay使用TXOP的截止时间,则在截止时间之后,Root AP再继续传输其他数据帧。
可选的,还可以并行的或串行的将TXOP分送给多个Relay。并行是指将不同的信道/资源块分配给不同的Relay,而串行则是指,在不同的时间段将TXOP共享给不同的Relay,可以采用周期性的时间指示,也可以对每个Relay分别指示各个Relay共享TXOP的时间。
图7为本申请实施例提供的通信方法实施例四的数据传输示意图。如图7所示,当传输机会共享指示信息中包括有效时长信息时,S302中的发送第二数据包,包括:
在接收到第一设备发送的同步帧后,根据有效时长信息,发送第二数据包。
示例性的,Root AP为每个Relay设置有效时长信息,即共享时间,同时在每个Relay的共享时间结束后,向下一个Relay发送一个同步帧(SYNC),指示下一个Relay开始使用共享的TXOP。示例性的,当Root AP的下一级关联有4个Relay,分别记为Relay1、Relay2、Relay3和Relay4,各个Relay下关联有站点。如图7所示,Root AP将信道1同时授予Relay1和Relay2,将信道2同时授予Relay3和Relay4,并为Relay1、Relay2、Relay3和Relay4分别指示了有效时长信息。例如,在信道1内,Relay1先在Relay1的共享时间内进行数据转发,然后,当Relay1的共享时间结束后,Root AP向Relay2发送同步帧,指示Relay2开始使用信道1,进行数据转发。
可选的,还可将一段时间分配给多个Relay,由多个Relay进行信道竞争,获取共享TXOP的使用权。
图8为本申请实施例提供的通信方法实施例五的数据传输示意图。如图8所示,当传输机会共享指示信息中包括信道信息时,第一数据包中还包括信标帧(Beacon),信标帧中包括限制接口窗口信息;限制接口窗口信息用于指示第一数据的目的地址对应的设备在限制接口窗口内,竞争信道信息指示的信道。
在S302发送第二数据包之前,具体包括:
根据限制接口窗口信息,确定限制接口窗口;在限制接口窗口内,确认竞争到信道信息指示的信道。
示例性的,Root AP通过Relay中的Relay STA的AID,指示限制接入窗口(Restricted Access Window,简称RAW)的类型为TXOP共享RAW,允许Relay STA对应的Relay AP在窗口时隙当中通过回退(backoff)来竞争信道,而不是允许Relay STA部分传输数据。当然,Root AP也可以直接跨BSS给多个Relay AP分配AID,直接采用Relay AP的AID。Root AP在限制接入窗口1中发送了第一数据包,包括给两个Relay1、Relay2和STA3发送的数据,并在限制接入窗口2中指示两个Relay可以在限制接入窗口2中进行回退竞争信道。未竞争到信道的设备在该限制接入窗口内可以进入节能模式。
可选的,可以在信标帧中通过相应的信息元素(Information Element,简称IE)来携带限制接口窗口信息RAW,如下所示。
其中,RAW控制中包含RAW的类型指示,RAW Slot定义允许该TXOP共享的时长;RAW开始时间指示允许TXOP共享开始的时间;Relay ID指示允许采用该窗口进行竞争的Relay的AID,可以采用Relay的Relay STA AID,也可以直接使用Relay AP的AID;信道指示指示Relay可以使用的信道和资源块。
TXOP共享的时频资源指示可以使TXOP共享更加灵活,也可以使Root AP同时分享TXOP给多个Relay,并允许Root AP继续使用该TXOP,提高了调度的灵活性,提升了系统信息传输的效率。
可选的,在上述任一实施例的基础上,Root AP确定Relay接收到第一数据包的方式,包括显式确认和隐式确认两种。
可选的,当为显式确认时,图9为本申请实施例提供的通信方法实施例六的数据传输示意图。如图9所示,在S302发送第二数据包之前,还包括:
中继设备接收第一设备发送的第一确认请求信息;
其中,第二数据包还包括根据第一确认请求信息发送的确认信息。
示例性的,第一确认请求信息集成在第一数据包中,还可以单独以第一数据帧的形式发送,Relay
根据第一确认请求信息发送的确认信息可以单独发送,也可集成在第二数据包中。
进一步的,如图9所示,第二数据包还包括第二确认请求信息;
中继设备在S302发送第二数据包之后,还包括:
中继设备接收第二数据包中的各目的地址对应的设备,根据第二确认请求信息发送的确认帧。
示例性的,第二数据包中还包括第二确认请求信息,第二确认请求信息中包括站点4和站点5的AID,从而使得站点4和站点5可在检测到自己的AID后,根据第二确认请求信息向Relay发送确认帧。可选的,当第二数据包中还包括第二数据时,根接入点在第二数据包中检测到自己的AID后,根据第二确认请求信息向Relay发送确认帧。
可选的,当为隐式确认时,一种可行的隐式确认方式:
第一设备侦听确认接收地址对应的设备发送的第二数据包中包括所有第一数据的目的地址。
具体的,当Root AP向Relay发送第一数据包后,Relay根据第一数据包中的第一数据,将其进行转发,因此,当Root AP检测到Relay转发的第二数据包时,可认为Relay已成功接收到第一数据包。故无需由Relay专门向Root AP发送确认帧。示例性的,Root AP检测第二数据包中包括的所有第一数据的目的地址,是否包括所有第一数据包中的第一设备的目的地址,若有缺少,则认为存在部分待转发未被Relay接收的第一数据。
另一种可行的隐式确认方式:
第一数据的媒体接入控制帧的高吞吐量控制字段承载有标识清单,标识清单包含成功接收到的所有第一数据的目的地址。
具体的,第二数据包中包括的Relay成功接收到的所有第一数据,当Relay利用多用户格式的第二数据包向多个目的STA发送数据,在HE-SIG-B中会携带目STA的AID,当Root AP发现目的STA的AID时,则认为之前发送的下行数据被正确接收,否则认为发送失败。若Relay采用频分多址接入(Frequency Division Multiple Access,简称FDMA),且第二数据包中不存在HE-SIG-B时,则在其为每个STA传输的第一数据中携带Relay成功接收的数据的AID清单(list),不仅包含每个STA自己的AID,还包含其他STA的AID,例如在图3中,若采用FDMA,在分别发送给STA4和STA5的数据中,分别携带STA4和STA5的AID。当Root AP收到任何一个数据,都可以得知之前发送的数据包中的数据是否有正确接收。该方法同样可以用于非FDMA的场景,对于图3至图9中的多用户格式的第二数据包,同样可以在MAC帧头中携带AID清单,本申请方案对AID清单所处于的数据包的格式不做限制。
示例性的,AID list可以存储在MAC帧头的高吞吐量控制(High Throughput Control,简称HTC)字段,可选的,可以利用HTC的新的一种变种高效聚合控制(High Efficient Aggregated Control,简称HE-A-Control)来承载一些控制信息。示例性的,如下所示,控制ID指示控制信令的类型。
AID list除了作为一个字段呈现,也可以专门设计一个MAC帧来承载AID list,接收地址设置成为广播地址。可选的,对于聚合MAC协议数据单元(Aggregated MAC Protocol Data Unit,简称A-MPDU),也就是多个MPDU(MAC帧)聚合起来的帧,若目的STA是多个,则可以在AID list中携带每个STA需要开始读取的MPDU的位置,也就是从第几个MPDU开始读取,A-MPDU的结构如下图所示:
同样,对于上行的TXOP共享,同样可以采用隐式确认机制。当Root AP向Relay发送触发帧,Relay向STA4和STA5转发触发帧,并将STA4和STA5根据触发帧发送的上行数据转发给Root AP时,Relay1在收到STA4和STA5的上行数据之后,不再回复确认帧给STA4和STA5,而是直接转发上行数据,当STA4和STA5发现Relay1的目的STA是Root AP时,则认为其传输给Relay的数据被正确接收。
隐式确认机制可以减少确认帧的开销,在多用户的情况下,设计隐式确认的机制,进一步提高系统效率。
可选的,在上述任一实施例的基础上,对传输机会的取回进行详细说明。
可选的,传输机会共享指示信息中包括传输机会共享截止时间。
可选的,在S302发送第二数据包之后,还包括:
中继设备接收第一设备发送的传输机会撤回指示;
中继设备根据传输机会撤回指示,终止传输机会共享。
可选的,在S302发送第二数据包之后,还包括:
中继设备向第一设备发送传输机会归还指示;
中继设备接收第一设备发送的非竞争截止指示;
中继设备根据非竞争截止指示,终止传输机会共享。
具体的,在第一设备将传输机会共享给中继设备后,第一设备可主动向中继设备发送撤回指示,以取回传输机会。可选的,还可由中继设备向第一设备发送触发帧形式的询问消息,使第一设备根据触发帧回复中继设备是否取回传输机会。也可由中继设备向第一设备发送归还指示,指示中继设备已经完成通信传输,可将传输机会归还,再由第一设备根据归还指示,确定是否收回。当第一设备确定收回时,向中继设备发送非竞争截止指示。
可选的,在上述任一实施例的基础上,第一数据包还包括传输机会二次共享指示标识,用于指示允许将传输机会二次共享。
具体的,第一设备可在第一数据包中携带二次共享指示指标,用于指示中继设备可将该传输机会进一步共享给其他设备。可选的,二次共享指示同样可以适用于逆向授予机制。
另一方面,结合Root AP以触发的形式向Relay索取数据帧或者向Relay和STA同时索取数据帧,对系统架构中的跨级数据传输进行详细说明。

具体的,在S1002中,Relay1在接收到第一数据包后,根据第一数据包中包括的第一目的地址,确定第二数据包,第二数据包中包括触发信息和第一目的地址STA4和STA5。Relay1在获取到第二数据包后发送第二数据包,以使STA4和STA5在接收到第二数据包后,根据第二数据包中的触发信息,向Relay1发送第一上行数据帧。
具体的,在S1003和S1004中,Relay1接收STA4和STA5发送的第一上行数据帧。并将各第一上行数据帧发送给Root AP,从而使得Root AP跨级获取到了数据。
可选的,在上述实施例的基础上,第一目的设备还包括中继设备Relay1;Root AP还向Relay1发送触发帧,同时向Relay1和关联在Relay1下的STA4和STA5索取数据。
根据Relay1向Root AP发送上行数据帧方式的不同,包括如下可行的实现方式:

图12为本申请实施例提供的通信方法实施例八的数据传输示意图,如图12所示,S1004发送上行数据帧之前,还包括:
中继设备根据触发信息,发送中继设备的第二上行数据帧。
具体的,中继设备在接收到触发信息时,立即响应。可选的,可在S1002发送第二数据包之前,发送中继设备的第二上行数据帧。可选的,也可将第二上行数据帧集成在第二数据包中,采用多用户格式进行发送。
另一种可行的实现方式:

具体的,中继设备在接收到触发信息时,没有立即响应。而是在接收到第一目的地址发送的第一上行数据帧之后,同时将第一上行数据帧和第二上行数据帧发送给第一设备。
进一步的,在图11、图12或图13所示实施例的基础上,第一数据包还包括触发信息的第三目的地址,第三目的地址为与第一设备关联且与中继设备同级的设备,示例性的,第三目的地址可以为图1中的STA2。

具体的,第一设备发送的触发信息,可同时向与第一设备关联的下级设备以及下下级设备索取数据,同时,通过发送时间信息,可指示各目的地址对应的设备发送上行触发帧的时间信息。示例性的,第一目的地址STA4和STA5提前将第一上行数据发送给Relay1,第二目的地址中继设备Relay1和第三目的地址STA2同时在时间信息指示的时刻向第一设备发送各自的上行数据帧,使得Root AP可在同一时间接收到第一、第二、第三上行数据帧。
图15示例性的在图13所示实施例的基础上,对本实施例进行说明。
通过允许Root AP跨级索取数据,进行统一控制,可以使得某些时延敏感业务可以更迅速的到达Root AP。

可选的,在上述任一实施例的基础上,第一数据包中还包括如下中的至少一项:共享传输节点集、共享传输帧类型集、共享传输业务类型集,与第一方面中相同,本申请对此不再赘述。
又一方面,Relay发送触发帧,同时向多个设备索取数据,索取到的数据可能为需要Relay转发的数据,多个设备可以为关联在Relay的不同侧的设备,也可以为未与Relay关联的设备。
图18为本申请实施例提供的通信方法实施例十三的流程示意图;图19为图18所示实施例十三的数据传输示意图。如图18和图19所示,该方法包括:

可选的,触发信息的第一目的地址还包括第二设备,第二设备与第一设备分别关联在Relay的不同侧,示例性的,第二设备可以为与Relay关联的STA。
可选的,触发信息的第一目的地址还包括未与Relay关联的设备,Relay可向未与Relay关联的设备发送触发帧以索取数据,还可通过向未与Relay关联的设备发送触发帧,以触发该未与Relay关联的设备向Relay发送关联申请信息,从而使Relay与该设备关联。
参考图19,Relay1同时向STA4、STA5和Root AP同时发送触发帧,索取数据帧。
进一步的,Relay1向STA4、STA5或Root AP索取到的数据帧可以为目的地址是Relay的数据帧,也可以是需要Relay转发的数据帧,在Relay接收到需要转发的数据帧之后,根据数据帧中的目的地址进行数据转发。
本申请实施例可以根据上述方法示例对中继设备、根节点设备、站点设备进行功能单元的划分,例如,可以对应各个功能划分各个功能单元,也可以将两个或两个以上的功能集成在一个处理单元中。
上述集成的单元既可以采用硬件的形式实现,也可以采用软件功能单元的形式实现。需要说明的是,本申请实施例中对单元的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。
