具体实施方式
本领域技术人员理解，现有技术提供的Wi-Fi传输方案无法支持RTA应用。
本申请发明人经研究发现，尽管Wi-Fi传输时延长的原因有多种，但其中一个原因在于数据分组持续时长(packet duration)的空口时间(air time)过长。为了能够按时传输RTA分组，实现RTA通信，当数据分组时长过长时应可以被要求中断。
本发明实施例提供一种信令传输方法，包括：配置指示信令，所述指示信令用于通知指示信令接收方动态地中止当前传输的数据包；发送所述指示信令。通过本发明实施例设置指示信令，可以使得接收到所述指示信令的终端中止当前传输的数据包，从而使得指示信令发送方可以快速取得发送机会以传输高时效性数据分组，有利于降低时延，为传输高时效性数据分组(例如，RTA分组)提供可行方案。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例的一种信令传输方法的流程示意图。所述信令传输方法可以由WLAN接入点(Access Point，简称AP)或站点执行。具体而言，所述信令传输方法可以包括以下步骤：
步骤S101，配置指示信令，所述指示信令用于通知指示信令接收方动态地中止当前传输的数据包；
步骤S102，发送所述指示信令。
更具体而言，AP和站点(Station，简称STA)可以使用相同身份识别码形成基本服务集(Basic Service Set，简称BSS)。BSS内的终端可以基于相同的服务集标识符(Service Set Identifier，简称SSID)进行通信。
在步骤S101中，当BSS内传输高时效性数据分组(例如，RTA分组)时，AP和站点可以在数据传输过程中，通过配置指示信令以动态地中止当前传输的较长数据包，减小数据分组长空口占用时长导致的时延，达到传输高时效性数据分组(例如，RTA分组)的目的。需要说明的是，对比现有技术，所述中断机制使得高时效性数据分组 因空口占用时长导致的时延可以变短。
在具体实施中，如果AP或站点需要传输RTA分组或其他高时效性数据分组，即待传输的数据分组为RTA分组或其他高时效性数据分组时，当发现第一链路空口正被某个时长过长的数据分组或是一组总时长过长的连续传输数据分组占用时，那么AP或站点可以在第二链路配置指示信令，以指示接收方(也可以称为指示信令接收方)动态地中止当前第一链路传输的数据包。
在步骤S102中，AP或站点可以发送所述指示信令。需要说明的是，所述指示信令可以是在不同于所述数据接收方传输当前传输的数据包所在链路的其他链路传输的。例如，所述指示信令是在第二链路传输的，所述当前传输的数据包是在第一链路传输的，所述第二链路指的是与第一链路不同的其他链路。在一个实施例中，所述第二链路可以为控制链路，通常仅传输控制信令。
进一步，接收到所述指示信令的AP或站点，即指示信令接收方可以在提取出所述指示信令之后，如果当前正在传输数据包(例如，聚合数据包)，则可以中断对所述正在传输的数据包的传输。
在一个实施例中，所述指示信令可以包括链路标识(也可称为链路编号或链路索引)，所述链路标识用于指向执行所述指示信令的终端所在的链路。该链路标识为发送所述指示信令的终端确定的，使得接收到所述指示信令的终端确定是否中止正在传输的数据包。处于该链路标识对应的链路上，且正在传输数据包的AP或站点，在接收到所述指示信令后，可以中止正在传输的数据包。如果所述指示信令可以包括链路标识，那么工作于该标识对应的链路上的AP或站点可以中止或中断对所述正在传输数据包的传输。
例如，多链路***中包括第一链路、第二链路和第三链路，假设第二链路为控制链路，通常仅传输控制信令，第一链路和第三链路为数据链路，可以传输数据包，在此条件下，当所述指示信令包括第一链路的标识时，工作于第一链路的AP或站点接收到该指示信令时， 可以中断当前传输的数据包；当所述指示信令包括第一链路的标识时，工作于第三链路的AP或站点接收到该指示信令时，可以丢弃该指示信令，不中断当前传输的数据包。
进一步，如果当前未传输数据包，则可以缩短此后传输的数据包，以满足所述高时效性数据分组的传输要求。
在一个实施例中，在发出包含所述指示信令之后，AP或站点还可以侦测所述指示信令接收方是否已中止对所述当前传输的数据包的发送。如果侦测结果表示所述指示信令接收方已中止对所述当前传输的数据包的发送，那么该AP或站点可以发送高时效性数据分组，进行高时效性通信，所述发送高时效性数据分组，可以是无需竞争或是采用较短的竞争窗口来取得发送机会。
在另一个实施例中，所述AP或站点可以在发出所述指示信令之后，接收所述指示信令接收方发送的指示反馈信令。其中，所述指示信令与指示反馈信令可以是数据帧，也可以是信号序列。在具体实施中，响应于所述指示信令，所述指示信令接收方可以发送所述指示反馈信令，所述指示反馈信令可以用于表示所述指示信令接收方即将停止或已停止对所述当前传输的数据包的发送。
在具体实施中，所述指示信令和/或指示反馈信令为数据帧时，可以用于通知指示信令接收方动态地中止当前传输的数据包，进一步，还可以携带链路标识。所述指示信令和/或指示反馈信令为信号序列(例如，单音调(tone))时，可以用于通知指示信令接收方动态地中止当前传输的数据包，也可以结合其他信令帧或特殊格式，从而可以包括所述链路标识。
在所述AP或站点在接收到所述指示反馈信令之后，可以在第一链路中确认原发送数据分组已停止后进行高时效性数据分组的传输。
图2是本发明实施例的一种信令接收方法的流程示意图。所述信令接收方法可以由接收到所述指示信令的数据接收方执行，所述数据 接收方可以是AP，也可以是站点。
具体而言，所述信令接收方法可以包括以下步骤：
步骤S201，接收指示信令，所述指示信令用于通知指示信令接收方动态地中止当前传输的数据包；
步骤S202，提取出所述指示信令。
更具体而言，在步骤S201中，AP或站点(可以称为指示信令接收方)可以接收指示信令。所述指示信令是其他站点或其他AP发出的，可以用于通知指示信令接收方动态地中止当前传输的数据包。
在一个实施例中，所述指示信令可以是其他站点或其他AP确定其待传输数据分组为RTA分组时配置的。
在步骤S202中，所述指示信令接收方可以提取出所述指示信令。
在具体实施中，所述指示信令接收方能够一并在多个链路/信道上进行数据收发。在此条件下，所述指示信令可以是在第二链路接收的。所述第二链路是不同于传输所述当前传输的数据包的第一链路的链路。也即，所述第一链路是所述指示信令接收方传输所述当前传输的数据包所在的链路。
如果所述指示信令接收方当前传输的数据包的时长较长，且恰好在所述其他链路接收到所述指示信令，那么所述指示信令接收方可以中断对所述当前传输的数据包的传输。
具体而言，当所述当前传输的数据包为包含多个数据分组的聚合数据包时，所述指示信令接收方可以中断当前传输的数据分组，并暂停传输除所述当前传输的数据分组之外的其他数据分组。
或者，当所述第二数据包为包含多个数据分组的聚合数据包时，所述AP或站点可以在传输完毕所述当前传输的数据分组后，暂停传输除所述当前传输的数据分组之外的其他数据分组。
在具体实施中，所述指示信令可以包括：链路标识，所述链路标 识可以用于指向执行所述指示信令的指示信令接收方所在的链路。
进一步，所述指示信令接收方可以发送指示反馈信令。所述AP或站点可以接收到指示反馈信令，所述指示反馈信令可以用于指示数据接收方接收到所述指示信令，并且即将停止或已停止对所述当前传输的数据包的发送。其中，所述指示反馈信令可以是数据帧，也可以是信号序列。
下面以典型应用场景为例进行阐述。
AP或站点可以发送指示信令。参考图3，图3是图1所示实施例的一种具体实施方式的流程示意图。其中，AP或站点可以在多个链路(例如多个传输信道)中传输数据分组和信令分组。图3示出的传输信道数量为2，分别为信道1和信道2。
继续参考图3，AP或站点可以在信道1中，发送聚合数据包。其接收方在成功接收所述聚合数据包之后，可以发送块确认(Block Acknowledgement)，AP或站点可以接收该块确认。在具体实施中，所述聚合数据包为聚合介质访问控制协议数据单元(Aggregated MAC Protocol Data Unit，简称AMPDU)，所述聚合数据包中的单个数据包可以为介质访问控制协议数据单元(MAC Protocol Data Unit，简称MPDU)。
在AP或站点传输聚合数据包期间，如果其他数据发送方(例如，具有RTA分组发送需求的站点或AP)产生待传输数据，且所述待传输数据为RTA分组或其他高时效性数据分组，那么其他数据发送方可以在信道2上发送指示信令，所述指示信令用于通知指示信令接收方动态地中止当前传输的数据包。如果所述AP或站点在信道1发送所述聚合数据包时，从信道2接收到所述指示信令(图中采用竖直虚线示意性地表示接收成功时刻)，那么所述AP或站点可以在传输完所述当前传输的数据包(即图中标记A的数据包)后，暂停传输除所述当前传输的数据分组之外的其他数据包(即图中标记为中断传输的数据包)。
进一步，所述AP或站点在收到所述指示信令后，还可以在信道2发送指示反馈信令，所述指示反馈信令用于表示所述指示信令接收方即将停止或已停止对所述当前传输的数据包的发送。所述其他数据发送方一旦接收到所述指示反馈信令，就可以在信道1进行RTA通信或其他高时效性数据分组通信。
本领域技术人员理解，尽管图未示出，但是当所述AP或站点在信道1发送所述聚合数据包时，又从信道2接收到所述其他数据发送方发送的指示信令时，所述AP或站点也可以在中断当前传输的数据包后，暂停传输除所述当前传输的数据包之外的其他数据包。
需要说明的是，发送所述指示信令的信道除采用其他传输信道外，还可以采用其他频段或其他链路。此外，接收到所述指示信令的站点或AP也可以不发送所述指示反馈信令，而是由具有RTA分组或其他高时效性数据分组的发送需求者自动检测，在确认聚合数据包的传输已中断后，所述具有RTA分组发送需求者可以进行RTA分组或其他高时效性数据分组传输。
需要说明的是，在图3中，所述指示信令和/或所述指示反馈信令均为数据帧。在实际应用中，所述指示信令和/或所述指示反馈信令可以为信号序列，图3中未示出。
本领域技术人员理解，所述步骤S201至步骤S202可以视为与上述图1所示实施例所述步骤S101至步骤S102相呼应的执行步骤，两者在具体的实现原理和逻辑上是相辅相成的。因而，关于信令接收方法以及术语可以参考图1所示实施例的相关描述，这里不再赘述。
由上，通过本发明实施例提供的技术方案，可以基于所述指示信令中止正在传输的数据包，缩短数据包占用的空口时间，有利于降低时延，为传输RTA分组或其他具有高时效性要求的数据分组提供可行方案。
