其中,本申请实施例中的AP和STA在结构上可以包括:介质访问控制层(media access control,MAC)和物理层(physical,PHY)。AP与STA可以通过物理层协议数据单元(PHY Protocol Data Unit,PPDU)进行PPDU传输,且当AP与STA使用的无线通信协议不同时,PPDU的帧结构也会有所不同。
在通信过程中,第一站点可以向第二站点汇报控制信息(control information),该控制信息承载在HT控制字段中。该第一站点可以是AP或者non-AP站点,该第二站点也可以是AP或者non-AP站点。该汇报可以是主动(unsolicited)汇报,也可以是索取式(solicited)汇报。
该HT控制字段可以携带在第一帧(例如,服务质量(quality of sevice,QoS)数据(data)帧,服务质量空(QoS Null)帧和管理帧)中,用于携带一些控制信息。如图2所示的本申请实施例提供的高吞吐率控制字段携带在服务质量数据帧中的格式示意图,在QoS数据帧中有一个HT控制字段,它通过帧控制(Frame Control)字段指示是否存在该HT控制字段。 HT控制字段的长度为4个字节。HT控制字段有三种类型,通过B0和B1比特进行区分。如图3所示的本申请实施例提供的高吞吐率控制字段的格式示意图,当B0=0时,对应的HT控制字段为高吞吐率(high throughput,HT)类型的HT控制字段;当B0=1,B1=0时,对应的HT控制字段为非常高吞吐量(very high throughput,VHT)类型的HT控制字段;当B0=1,B1=1时,对应的HT控制字段为高效率(high efficiency,HE)类型的HT控制字段。
其中,HE类型的HT控制字段中的B2-B31部分称作聚合控制(A-control)字段(subfield)。如图4所示的本申请实施例提供的一种聚合控制字段的格式示意图,聚合控制字段中包括控制列表(Control List)和填充(Padding)部分。其中,控制列表的长度可变,其包括一个或者多个控制子字段(Control subfield);填充部分包括0个或更多的比特。如图5所示的本申请实施例提供的聚合控制字段中的一个控制子字段的格式示意图,一个控制子字段包括一个4比特的控制标识(Control ID)和控制信息(Control Information)。该控制标识用于标识控制信息。控制标识和其对应的控制信息的长度如下表1所示:
表1
Figure PCTCN2022093067-appb-000001
在表1中,4个比特的控制标识可以用于标识16种类型的控制信息。其中,控制标识为 0-6分别用于标识7种HE以及HE之前的控制信息;控制标识7,8,10分别用于标识3种EHT的控制信息;控制标识为9,11-14保留(另一种说法是7-9分别用于标识3种EHT的控制信息,10-14保留);控制标识为15,用于指示忽略该聚合控制字段中该控制标识之后的比特,该控制标识对应的控制信息占26个比特,即忽略该聚合控制字段中该控制标识对应的控制信息。其中,控制标识为15(即“1111”),其对应的控制信息也设置为全1。
目前IEEE802.11be中已经新增一部分类型的控制信息,而表1中只剩余5种控制标识尚未使用。后续11be标准中可能会引入更多类型的控制信息,这样就有必要对目前的控制信息的类型进行扩展,以满足11be以及下一代标准中需要引入更多类型的控制信息的需求。
在本申请的一个实施例中,如图6所示的本申请实施例提供的一种扩展控制信息的类型的示意图,可以将上述表1中的控制标识为15对应的控制信息(“第一控制信息”)改为用于指示该第一控制信息包括扩展控制子字段,其中,第一控制信息为m个比特,m=26。上述规则主要针对第一帧的接收站点,即第二站点,是EHT站点或EHT的下一代站点。即当该第一帧发给HE站点时,保持之前的规则不变,即该控制标识用于指示该控制标识之后的比特可以忽略。当该第一帧发送给EHT站点或EHT的下一代站点的时候,表示是对控制标识的扩展。该控制标识对应的第一控制信息的格式如图7所示。第一控制信息中包括扩展控制列表(Extended Control List)和Padding部分,其中扩展控制列表包括一个或多个扩展控制子字段(Extended Control subfield);Padding部分包含0个或多个比特。Padding部分如果存在的话,其位于最后一个扩展控制子字段的后面,使得第一控制信息的长度为26比特。第二站点是EHT站点或EHT的下一代站点的时候,解析到该控制标识为15,则获取扩展控制子字段中的控制信息。
如图8所示的本申请实施例提供的扩展控制列表中的一个扩展控制子字段的格式示意图,该扩展控制子字段包括扩展控制标识(Extended Control ID)和控制信息(“第二控制信息”),其中,扩展控制标识为某一特定长度,例如可以为4~6个比特的其中之一,第二控制信息的长度可变。该扩展控制标识用于标识第二控制信息的类型。示例性地,第一控制信息和第二控制信息仅用于区分:第一控制信息是表1中的控制标识对应的控制信息,第二控制信息是指扩展控制标识对应的控制信息,第一控制信息和第二控制信息均是用作不同用途的控制功能,其控制信息的类型不同而已。
下面实施例还提供一种扩展控制信息的类型的方法,该方法中第一站点可以提供更多类型的控制信息,且第一控制信息的长度可变,从而可以灵活地聚合其它类型的控制信息;第二站点在接收到第一帧时,获取到第一控制子字段,可以解读该第一控制子字段的第一控制信息包括扩展控制子字段,从而获取扩展控制子字段中的第二控制信息。
如图9所示,为本申请实施例提供的一种通信方法的流程示意图,该方法可以包括以下步骤:
S901.第一站点生成第一帧。
该第一站点可以是AP或者non-AP站点。该第一帧可以是上述QoS数据帧、QoS空帧、或管理帧等。
其中,该第一帧包括HT控制字段。当HT控制字段中的B0=1,B1=1时,HT控制字段中的B2-B31称为聚合控制字段。如图10所示的本申请实施例提供的又一种聚合控制字段的格式示意图,聚合控制字段包括第一控制子字段。其中,第一控制子字段包括控制标识以及与该控制标识对应的控制信息(“第一控制信息”)。该第一控制信息包括扩展控制子字段列表(Extended Control subfield list)和填充部分。其中,该扩展控制子字段列表包括一个或多个 扩展控制子字段,如图11所示的本申请实施例提供的一个扩展控制子字段的格式示意图,扩展控制子字段包括扩展控制标识(Extended Control ID)和该扩展控制标识对应的控制信息(“第二控制信息”),该扩展控制标识用于标识所述第二控制信息的类型。
示例性地,当该第一控制子字段中的控制标识为第一值时,用于指示该控制标识对应的第一控制信息包括扩展控制子字段列表和填充部分。示例性地,该第一值可以是9~15中的一个值。可以任意选取9~15中的一个值,也可以是固定选取9~15中的一个值。其中,9~14,或者9,11-14为当前尚未被使用的控制标识(即表1中保留的控制标识)。
示例性地,上述第一控制信息和第二控制信息仅用于区分:第一控制信息是上述表1中的除第一值以外的控制标识对应的控制信息,第二控制信息是扩展控制标识对应的控制信息,第一控制信息和第二控制信息均是用作不同用途的控制功能,其控制信息的类型不同而已。
从而针对上述表1中剩余的控制标识不足的情况,本实施例可以通过第一控制子字段结合扩展控制标识字段来扩展出更多类型的控制信息。在下面的实施例中以Control ID=15为例描述本实施例的方案。当第一值为其它尚未被使用的控制标识的时候有少许不同,会在后面加以说明。
上述扩展控制标识是新增字段,可以包括4~6个比特。当扩展控制标识为4,5或6比特的情况下,分别扩展出来的控制信息的类型可以多达16,32或64种。下面实施例中以扩展控制标识为4比特为例进行介绍,实际实现中也可以采用其它长度。
在本实施例中,以Control ID=15为例,控制标识、扩展控制标识和其对应的控制信息的长度如下表2所示:
表2
Figure PCTCN2022093067-appb-000002
在表2中,扩展控制标识为4比特,从而可以扩展16种类型的第二控制信息。其中,第 二控制信息的长度由扩展控制标识确定。
在本实施例中,图10中的第一控制信息的长度是可变的。具体地,在图11所示的一个扩展控制子字段的格式示意图中,由于第一控制信息包括扩展控制子字段,第一控制信息为m个比特,则m<26,m为正整数。进一步地,假设扩展控制子字段中的扩展控制标识为n个比特,则n≤m<26。或者,假设扩展控制子字段中的扩展控制标识为n个比特,第一控制信息包括x个扩展控制子字段,扩展控制子字段的长度为l x,则x*(n+l x)<26,其中,n,x为正整数,x=1,2,…。由于第二控制子字段中的第一控制信息的长度是可变的,从而如图10所示,该聚合控制字段中除了包括该第一控制子字段,还可以聚合一个或多个第二控制子字段(如图10所示,聚合控制字段还包括第二控制子字段1、第二控制字段2等)。其中,该第一控制子字段与第二控制子字段的区别在于,该第一控制子字段中的控制信息子字段包括扩展控制子字段列表和填充部分。而第二控制子字段的控制信息子字段包括固定长度的特定控制信息。
示例性地,由于该第一控制子字段的第一控制信息中包括扩展控制子字段列表,其长度可变,因此,如图10所示,当该第一控制子字段与一个或多个第二控制子字段聚合的时候,第一控制子字段位于聚合控制字段中所有第二控制子字段之后,是聚合控制字段的最后一个控制子字段。换句话说,如果该第一控制子字段后面还有其它控制子字段的话是不可行的。因为该第一控制子字段是变长的,第二站点无法确定该第一控制子字段在哪里结束,从而无法对聚合控制字段进行正确解读。
另外,由于将Control ID=15规定为对控制标识进行扩展,不再包含聚合控制字段中的控制标识之后的后续比特可以忽略的含义。因此需要使用一个特定的扩展控制标识来指示第二站点(EHT站点、或ETH站点及ETH的下一代站点)可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特。本实施例中,当扩展控制标识为第二值时,用于指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特。后续比特可以包括聚合控制字段中的扩展控制标识子字段之后的部分或所有比特。
示例性地,如表2所示,可以使用扩展控制标识为全1来指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特。从而可以把聚合控制字段中的扩展控制标识子字段之后的后续比特也全部设置为全1,这样所使用的序列跟HE站点使用的比特是相同的(全1序列),方便实现。当然,聚合控制字段中的扩展控制标识子字段之后的后续比特设置为全1之外的其它序列也是可以的。当扩展控制标识为4比特的情况下,对应地就是使用Extended Control ID=15来指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特;当扩展控制标识为5比特的情况下,对应地就是使用Extended Control ID=31来指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特;当扩展控制标识为6比特的情况下,对应地就是使用Extended Control ID=63来指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特。当然,该第二值也可以取其它值来指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特,本申请不作限定。
由于只有当聚合控制字段中没有任何一个第二控制子字段或者扩展控制子字段需要承载的情况下,才会指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特。因此当使用Extended Control ID=15来指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特的情况下,在一个实现中,该第一控制子字段可以是聚合控制字段中的第一个控制子字段,扩展控制标识位于第二控制信息的开始部分。在另一个实现中, 该第一控制子字段可以是聚合控制字段中的唯一的一个控制子字段,扩展控制标识位于第二控制信息的开始部分。
上文中主要以Control ID=15来指示控制信息类型的扩展,此外也可以使用其它保留的控制标识(例如Control ID=14)来指示控制信息类型的扩展。其中,使用Control ID=15,相当于复用了表1中的Control ID=15,即节省了一个控制标识。但是它需要使用一个特定的扩展控制标识来指示第二站点可以忽略聚合控制字段中的扩展控制标识子字段之后的后续比特。也就是说第二站点要联合Control ID=15和扩展控制标识来知道后续比特可以忽略。而如果采用其它保留的控制标识(例如Control ID=14)来指示控制信息类型的扩展,第二站点可以采用和HE站点一样的方式来判断聚合控制字段中的扩展控制标识子字段之后的后续比特可以忽略,即通过读取Control ID=15就可以确定聚合控制字段中的扩展控制标识子字段之后的后续比特可以忽略。
另外,当该第一控制子字段中的扩展控制子字段列表没有把聚合控制字段中剩余比特使用完时,需要填充一些比特来使得聚合控制字段长度为30比特。在本实施例中,Padding部分位于扩展控制子字段列表之后,换句话说位于最后一个扩展控制子字段中的第二控制信息之后。
在一个实现中,将Padding部分设置为全0序列,实现方便。然而,是否可以采用全0序列来设置Padding部分取决于Extended Control ID=0对应的第二控制信息的长度。如图12和图13所示的本申请实施例提供的第二站点解读的两种第一控制子字段的格式示意图,如果该第一控制子字段中承载了一个Extended Control subfield x,Extended Control ID=x对应的第二控制信息为空,则第二站点无法区分它是属于图12和图13中的哪一种,存在解读模糊性。假设扩展控制标识为n比特,Extended Control ID=0对应的第二控制信息子字段的长度为m比特。由于Extended Control ID=x对应的第二控制信息可能为0比特,所以Extended Control subfield x最小的长度为n。当n+n+m<=26的时候就会存在以上解读模糊性。要想消除以上的解读模糊性,则设置2*n+m>26,即m>26-2*n。当n=4的情况下,m>18;当n=5的情况下,m>16;当n=6的情况下,m>14。
因此,当Extended Control ID=0对应的第二控制信息子字段的长度大于18的情况下,可以使用全0来设置Padding部分。
在另一个实现中,也可以使用全1序列来设置Padding部分。这样,也与前述使用控制的控制标识为全1来指示聚合控制字段中的扩展控制标识子字段之后的后续比特可以忽略是对应的。
以上针对Padding部分的设计是基于如图7所示的结构来介绍的,即Padding部分属于第一控制子字段中的控制信息的一部分。但是还有一种理解方式是当聚合控制字段中出现该第一控制子字段的情况下如果需要在聚合控制字段结尾进行Padding的话,该Padding部分不属于该第一控制子字段的一部分,即图7中不再包括Padding部分。应理解这只是描述上的一种变化,并不改变Padding序列的设计以及其功能。如果本申请方案中Padding部分为全1序列或者y个1加任意比特的情况下,这就意味这聚合控制字段的Padding部分有两种设置方式。如果聚合控制字段中不包含该第一控制子字段,则Padding部分为全0序列;如果聚合控制字段中包含该第一控制子字段,则Padding部分为全1序列或者y个1加任意比特。其中,y为正整数。
S902.第一站点向第二站点发送第一帧。
第二站点也可以是AP或者non-AP站点。第二站点接收该第一帧,
S903.第二站点接收到第一帧后,获取扩展控制子字段中的第二控制信息。
第二站点接收到第一帧后,解析该第一帧。该第一帧包括聚合控制字段,该聚合控制字段包括第一控制子字段。当第二站点获取到该第一控制子字段时,第二站点会进一步解析扩展控制子字段中的扩展控制标识,来确定扩展控制标识对应的第二控制信息的类型,从而可以获取更多类型的控制信息。
进一步地,当该第二站点解析到该第一控制子字段中的控制标识为第一值,则可以识别该第一控制子字段中的第一控制信息包括扩展控制子字段列表。从而第二站点会进一步解析扩展控制子字段中的扩展控制标识,来确定扩展控制标识对应的第二控制信息的类型,从而可以获取更多类型的控制信息。
示例性的,该第二站点可以为EHT站点,当该EHT站点解析其中一个扩展控制标识为第二值时,该EHT站点忽略聚合控制字段中该扩展控制标识之后的比特。该第二值可以为15,31或63中的一个值。其中,该第一控制子字段为聚合控制字段中的第一个控制子字段,该扩展控制标识位于第二控制信息的开始部分;或者,该第一控制子字段为聚合控制字段中的唯一的控制子字段,该扩展控制标识位于第二控制信息的开始部分。
示例性的,该第二站点可以为EHT的下一代站点,当该EHT的下一代站点解析其中一个扩展控制标识为第二值时,该EHT的下一代站点忽略聚合控制字段中该扩展控制标识之后的比特。该第二值可以为15,31或63中的一个值。其中,该第一控制子字段为聚合控制字段中的第一个控制子字段,该扩展控制标识位于第二控制信息的开始部分;或者,该第一控制子字段为聚合控制字段中的唯一的控制子字段,该扩展控制标识位于第二控制信息的开始部分。
根据本申请实施例提供的一种通信方法,该方法中第一站点可以提供更多类型的控制信息,且第一控制信息的长度可变,从而可以灵活地聚合其它类型的控制信息;第二站点在接收到第一帧时,获取到第一控制子字段,可以解读该第一控制子字段的第一控制信息包括扩展控制子字段,从而获取扩展控制子字段中的第二控制信息。
