除非另外定义,这里使用的所有术语(包括技术术语和科学术语),具有与本公开所属领域中的普通技术人员的一般理解相同的意义。
图1是示出无线通信场景的示例性示图。
在无线局域网中,一个基本服务集(BSS)可以由多个站点(STA:station)构成。STA可以包括接入点(AP:Access Point)设备以及与AP设备通信的一个或多个非AP(non-AP)设备。一个基本服务集可以通过其AP设备连接到分配系统DS(Distribution System),然后再接入到另一个基本服务集,构成扩展的服务集ESS(Extended Service Set)。
AP设备是用于无线网络的无线交换机,也是无线网络的核心。AP设备可以用作无线基站,主要是用来连接无线网络及有线网络的桥接器。利用这种AP设备,可以整合有线及无线网络。
作为示例,AP设备可以包括软件应用和/或电路,以使无线网络中的其他类型节点可以通过AP与无线网络外部及内部进行通信。例如,AP设备可以是配备有Wi-Fi(Wireless Fidelity,无线保真)芯片的终端设备或网络设备。
作为示例,non-AP设备可以包括但不限于:蜂窝电话、智能电话、可穿戴设备、计算机、个人数字助理(PDA)、个人通信系统(PCS)设备、个人信息管理器(PIM)、个人导航设备(PND)、全球定位系统、多媒体设备、物联网(IoT)设备等。
虽然在图1中示出了一个AP设备与三个non-AP设备(non-AP 1、non-AP 2、non-AP 3)进行通信,但是这仅是示例性的,本公开的实施例不限于此,例如,AP设备和non-AP设备可以具有任何数量和/或任何类型。
在本公开的示例实施例中,AP设备和non-AP设备可以是多连接设备(MLD:multi-link device),例如,可以被分别表示为AP MLD和non-AP STA MLD。也就是说,即,AP MLD和non-AP STA MLD支持在同一时刻能够在多连接下同时发送和/或接收的功能。例如,AP MLD与non-AP STA MLD之间可以存在处于不同频率下的多个连接,例如,2.4GHz、5GHz、6GHz下的连接等,或2.4GHz、5GHz、6GHz下的几个相同或不同带宽的连接。此外,在每个连接下可以存在多个信道。根据本公开的实施例提供的通信方法和通信装置可以应用于AP MLD与non-AP STA MLD之间的通信,即,可以应用于多连接通信环境。
在目前的无线通信技术中,不仅可以使用现有的QAM调制方式,例 如,1k QAM等,还期望采用4k QAM(也可以称为4096-QAM)的调制方式。此外,还在正交频分多址(OFDMA:Orthogonal Frequency Division Multiple Access)中定义了单资源单元(在下文可以利用“RU”来表示)和复合资源单元(在下文可以利用“MRU”来表示)。
在现有技术中,当最大支持1k QAM时,支持的RU可以为:26-tone(子载波)、52-tone、106-tone、242-tone、484-tone、996-tone及2*996-tone,此外,考虑到硬件的差异性,所以对1k QAM是否能够应用到小于242-tone的RU(例如,26-tone、52-tone、106-tone)的能力进行了标识。然而,在目前的技术中,最大可以支持4k QAM并且既可以应用单资源单元(RU)也可以应用复合资源单元(MRU),其中,小于242-tone的RU可以为:26-tone、52-tone、106-tone;并且小于242-tone的MRU可以为:52+26-tone、106+26-tone。考虑到非接入点的站点及接入点硬件的差异化,需要对4k是否能够应用到小于242-tone的RU&MRU做出标识,但现有技术仅能标识1k QAM以及单资源单元的情况,因此需要对此进行改进。在下文中,为了描述的简明,本公开的实施例集中描述了小于242-tone的RU&MRU以及1k QAM和4k QAM的示例,但是本公开不限制于此,例如,根据本公开的实施例提供的通信方法和通信装置也可以应用于其他类型的资源单元(例如,242-tone、484-tone、484+242-tone、996-tone、996+484-tone、996+484+242-tone、2*996-tone、2*996+484-tone、3*996-tone、3*996+484-tone、4*996-tone等)以及其他类型的QAM。此外,将理解,上述关于资源单元(RU和MRU)的数值示例仅是说明性的,而不是限制性的。
图2是示出根据本公开的示例实施例的通信方法的流程图。图2所示的通信方法可以是在发送方执行的方法,对应地,稍后参照图3描述的另一通信方法可以是在接收方执行的方法。根据实施例提供的图2和图3所示的方法可以应用于多连接通信,也就是说,发送方可以是上述的AP MLD和non-AP STA MLD中的一者,对应地,接收方可以是AP MLD和non-AP STA MLD中的另一者。然而,本公开不限于此,图2和图3所描述的通信方法也可以用于除了多连接通信之外的其他通信。
参照图2,在步骤210中,可以确定第一消息帧。在多连接通信的情况下,可以在发送方与接收方之间的多个连接中的任一连接下确定第一消息帧。根据本公开的实施例,确定第一消息帧的方式可以有很多种,例如:发送方可以根据以下的至少一种情况来生成第一消息帧:网络情况、负载情况、发送/接收设备的硬件能力、业务类型、相关协议规定;对此本公开实施例不作具体限制。在本公开的实施例中,发送方还可以从外部获取该第一消息帧,对此本公开实施例不作具体限制。
在发送方为AP MLD的情况下,第一消息帧可以是信标(beacon)帧、探测响应(probe response)帧、关联响应(association response)帧或者重关联响应(Re-association response)帧;在发送方为non-AP STA MLD的情况下,第一消息帧可以是探测请求(probe request)帧、关联请求(association request)帧或者重关联请求(Re-association request)帧。将理解,在此描述的第一消息帧的示例仅是说明性的,而不是对本公开的限制,其他类型的帧包含在本公开的范围内。
在本公开的实施例中,第一消息帧可以包括第一信息,其中,第一信息可以指示对于第一大小的单资源单元和/或复合资源单元应用于第一类型的QAM的支持能力。在下文中,第一类型的QAM的示例可以是4096-QAM,也就是说,第一信息可以指示对于第一大小的单资源单元和/或复合资源单元应用于4096-QAM的支持能力。根据本公开的实施例,第一大小的单资源单元和/或复合资源单元可以为小于242-tone的资源单元。根据实施例,复合资源单元可以由单类型的资源单元组成。在一个实施例中,复合资源单元可以由两个特定的单类型的资源单元组成,且与带宽相关。例如,复合资源单元可以至少包括:第一单类型的资源单元和第二单类型的资源单元,其中,第一单类型的资源单元与第二单类型的资源单元具有不同数量的子载波(tone)。也就是说,复合资源单元可以由至少两种不同的单类型的资源单元组成。根据本公开的实施例,小于242-tone的单资源单元(RU)可以为26-tone、52-tone、106-tone,小于242-tone的复合资源单元(MRU)可以为52+26-tone、106+26-tone。将理解,在此描述的RU和MRU的数值示例仅是说明性的,而不是限制性的,其他可行的RU和 MRU也包含在本公开的范围内。
在本公开的另一实施例中,第一消息帧可以包括第二信息,其中,第二信息可以指示对于第一大小的单资源单元和/或复合资源单元应用于第二类型的QAM的支持能力。在下文中,第二类型的QAM的示例可以是1024-QAM,也就是说,第二信息可以指示对于第一大小的单资源单元和/或复合资源单元应用于1024-QAM的支持能力。此外,类似于上文的描述,小于242-tone的单资源单元(RU)可以为26-tone、52-tone、106-tone,小于242-tone的复合资源单元(MRU)可以为52+26-tone、106+26-tone。
将理解,根据发送方设备的配置(例如,硬件和/或软件配置),第一消息帧可以携带第一信息和第二信息二者、也可以携带第一信息和第二信息中的一者。根据本公开的实施例,在第一信息被设置为支持第一大小的单资源单元和/或复合资源单元应用于4096-QAM的情况下,第二信息可以被设置为支持第一大小的单资源单元和/或复合资源单元应用于1024-QAM。在此情况下,可以考虑省略第二信息(针对1024-QAM),也可以不省略。
此外,根据本公开的实施例,第一信息(针对4096-QAM)和/或第二信息(针对1024-QAM)可以包括在第一消息帧的极高吞吐量(EHT)物理层(PHY)能力信息(例如,EHT PHY能力信息元素)中。
如上文所描述的实施例,在发送方为AP MLD的情况下,第一消息帧可以是信标帧、探测响应帧、关联响应帧或者重关联响应帧。在此情况下,EHT PHY能力信息可以封装在AP MLD将要发送的上述帧中。例如,以第一消息帧为信标帧作为示例进行描述,EHT PHY能力信息在信标帧的帧体(frame body)中的顺序(order)号可以为90,然而,这仅是示例性的,本公开不限于此。此外,如上文所描述的实施例,在发送方为non-AP STA MLD的情况下,第一消息帧可以是探测请求帧、关联请求帧或者重关联请求帧。在此情况下EHT PHY能力信息可以封装在non-AP STA MLD将要发送的上述帧中。
例如,可以在EHT PHY能力信息元素中标识第一信息和/或第二信息。然而,这仅是示例性描述,本公开不限于此,也可以在其他信息元素中携 带第一信息和/或第二信息。稍后将参照表1至表4对第一信息和第二信息进行详细描述。
首先参照表1和表2详细描述第一信息(针对4096-QAM)的实施例。
根据本公开的实施例,第一信息可以包括第一标识和第二标识。第一标识可以指示对于第一大小的单资源单元和复合资源单元应用于4096-QAM接收的支持能力;第二标识可以指示对于第一大小的单资源单元和复合资源单元应用于4096-QAM发送的支持能力。以第一大小的单资源单元和复合资源单元为小于242-tone的资源单元作为示例进行描述,第一信息可以如下面的表1所示。
表1
Rx 4096-QAM<242-tone support Tx 4096-QAM<242-tone support
参照表1,作为示例,Rx 4096-QAM<242-tone support可以对应于第一标识,以指示对于第一大小的单资源单元和/或复合资源单元应用于4096-QAM接收的支持能力。例如,Rx 4096-QAM<242-tone support可以指示小于242-tone的单资源单元和/或小于242-tone的复合资源单元应用于4096-QAM接收的支持能力。在该第一标识(Rx 4096-QAM<242-tone support)被设置为第一值(例如,“1”)的情况下,可以指示发送方支持将小于242-tone的单资源单元和/或复合资源单元应用于4096-QAM接收。在该第一标识(Rx 4096-QAM<242-tone support)被设置为第二值(例如,“0”)的情况下,可以指示发送方不支持将小于242-tone的单资源单元和/或复合资源单元应用于4096-QAM接收。
参照表1,作为示例,Tx 4096-QAM<242-tone support可以对应于第二标识,以指示对于第一大小的单资源单元和复合资源单元应用于4096-QAM发送的支持能力。例如,Tx 4096-QAM<242-tone support可以指示小于242-tone的单资源单元和小于242-tone的复合资源单元应用于4096-QAM发送的支持能力。在该第二标识(Tx 4096-QAM<242-tone support)被设置为第一值(例如,“1”)的情况下,可以指示发送方支持将小于242-tone的单资源单元和复合资源单元应用于4096-QAM发送。在该第二标识(Tx 4096-QAM<242-tone support)被设置为第二值(例如,“0”)的情况下,可以指示发送方不支持将小于242-tone的单资源单元 和复合资源单元应用于4096-QAM发送。根据本公开的实施例,在发送方为接入点(例如,AP MLD)的情况下,第二标识(Tx 4096-QAM<242-tone support)可以保留(reserved),这是因为可以默认AP MLD支持全功能,即,支持所有功能。
根据本公开的实施例,可以利用一个比特位一起标识RU以及MRU的情况,即,表1中的第一标识和第二标识均可以具有一个比特位。具体地,Rx 4096-QAM<242-tone support可以被设置为“0”,以标识不支持小于242-tone的子载波(例如,26-tone、52-tone、52+26-tone、106-tone、106+26-tone)用于4096-QAM(4k QAM)接收,而被设置为“1”时,标识支持;Tx 4096-QAM<242-tone support可以被设置为“0”,以标识不支持小于242-tone的子载波(例如,26-tone、52-tone、52+26-tone、106-tone、106+26-tone)用于4096-QAM(4k QAM)发送(针对AP MLD侧,Tx 4096-QAM<242-tone support保留),而被设置为“1”时,标识支持。
也就是说,在参照表1描述的实施例中,针对4096-QAM接收,可以仅利用第一标识(例如,具有一个比特位的Rx 4096-QAM<242-tone support)同时指示小于242-tone的单资源单元和小于242-tone的复合资源单元的支持能力;针对4096-QAM发送,可以利用第二标识(例如,具有一个比特位的Tx 4096-QAM<242-tone support)同时指示小于242-tone的单资源单元和小于242-tone的复合资源单元的支持能力。
将理解,上述第一标识和第二标识具有一个比特位的示例仅是为了说明,而不是对本公开的限制。例如,第一标识和第二标识均可以具有多个比特位,以指示选择性地支持小于242-tone的资源单元之中的哪种资源单元应用于4096-QAM。例如,多个比特位可以分别与小于242-tone的单资源单元和小于242-tone的复合资源单元相对应。以第一标识作为示例进行描述,第一标识(Rx 4096-QAM<242-tone support)可以具有三个比特位,当第一标识被设置为001时,可以指示将26-tone用于4096-QAM接收;当第一标识设置为011时,可以指示将52-tone用于4096-QAM接收;当第一标识设置为010时,可以指示将106-tone用于4096-QAM接收;当第一标识设置为100时,可以指示将26-52-tone用于4096-QAM接收;当第 一标识设置为101时,可以指示将106-52-tone用于4096-QAM接收。将理解,上述设置方式仅是示例性的,本公开不限于此,例如,当第一标识可以被设置为111时,可以指示所有小于242-tone的单资源单元和复合资源单元均可以应用于4096-QAM接收。此外,上述第一标识的设置示例也可以应用于第二标识,为了简明,在此省略重复的描述。
此外,参照上述的实施例,第一信息可以包括在EHT PHY能力信息中,因此,表1所示的第一标识(Rx 4096-QAM<242-tone support)和第二标识(Tx 4096-QAM<242-tone support)可以是EHT PHY能力信息中的标识位,并且EHT PHY能力信息可以被封装在如上所述的第一消息帧中。
根据本公开的另一实施例,第一信息可以包括第三标识和第四标识。在该实施例中,第三标识和第四标识均可以包括多个比特位(例如,至少两个比特位)。例如,第三标识中的至少一个比特位可以指示对于第一大小的单资源单元应用于4096-QAM接收的支持能力,第三标识中的至少一个比特位可以指示对于第一大小的复合资源单元应用于4096-QAM接收的支持能力,第四标识中的至少一个比特位可以指示对于第一大小的单资源单元应用于4096-QAM发送的支持能力,第四标识中的至少一个比特位可以指示对于第一大小的复合资源单元应用于4096-QAM发送的支持能力。以第一大小的单资源单元和复合资源单元为小于242-tone的资源单元作为示例进行描述,第一信息可以如下面的表2所示。

参照表2,第一信息的第三标识可以包括Rx 4096-QAM<242-tone RU support和Rx 4096-QAM<242-tone MRU support。为了描述的简明,第三标识可以被定义为具有两个比特位,并且这两个比特位可以分别对应于表2的Rx 4096-QAM<242-tone RU support和Rx 4096-QAM<242-tone MRU support。然而,本公开的实施例不限于此,第三标识可以具有更多个比特位。例如,第三标识中的Rx 4096-QAM<242-tone RU support可以具有多个比特位,以指示选择性地支持小于242-tone的单资源单元之中的哪种资源单元应用于4096-QAM接收。例如,第三标识中的Rx  4096-QAM<242-tone MRU support可以具有多个比特位,以指示选择性地支持小于242-tone的复合资源单元之中的哪种资源单元应用于4096-QAM接收。
第三标识的至少一个比特位(例如,对应于Rx 4096-QAM<242-tone RU support的比特位)可以指示小于242-tone的单资源单元(例如,26-tone、52-tone、106-tone)应用于4096-QAM接收的支持能力。在Rx 4096-QAM<242-tone RU support被设置为第三值(例如,1)的情况下,可以指示支持;而被设置为第四值(例如,0)的情况下,可以指示不支持。
第三标识的至少一个比特位(例如,对应于Rx 4096-QAM<242-tone MRU support的比特位)可以指示小于242-tone的复合资源单元(例如,52+26-tone、106+26-tone)应用于4096-QAM接收的支持能力。在Rx 4096-QAM<242-tone MRU support被设置为第三值(例如,1)的情况下,可以指示支持;而被设置为第四值(例如,0)的情况下,可以指示不支持。
也就是说,针对4096-QAM接收,第三标识可以具有多个比特位以将RU和MRU分开进行标识。
参照表2,第一信息的第四标识可以包括Tx 4096-QAM<242-tone RU support和Tx 4096-QAM<242-tone MRU support。为了描述的简明,第四标识可以被定义为具有两个比特位,并且这两个比特位可以分别对应于表2的Tx 4096-QAM<242-tone RU support和Tx 4096-QAM<242-tone MRU support。然而,本公开的实施例不限于此,第四标识可以具有更多个比特位。例如,第四标识中的Tx 4096-QAM<242-tone RU support可以具有多个比特位,以指示选择性地支持小于242-tone的单资源单元之中的哪种资源单元应用于4096-QAM发送。例如,第四标识中的Tx 4096-QAM<242-tone MRU support可以具有多个比特位,以指示选择性地支持小于242-tone的复合资源单元之中的哪种资源单元应用于4096-QAM发送。
第四标识的至少一个比特位(例如,对应于Tx 4096-QAM<242-tone  RU support的比特位)可以指示小于242-tone的单资源单元(例如,26-tone、52-tone、106-tone)应用于4096-QAM发送的支持能力。在Tx 4096-QAM<242-tone RU support被设置为第三值(例如,1)的情况下,可以指示支持;而被设置为第四值(例如,0)的情况下,可以指示不支持。
第四标识的至少一个比特位(例如,对应于Tx 4096-QAM<242-tone MRU support的比特位)可以指示小于242-tone的复合资源单元(例如,52+26-tone、106+26-tone)应用于4096-QAM发送的支持能力。在Tx 4096-QAM<242-tone MRU support被设置为第三值(例如,1)的情况下,可以指示支持;而被设置为第四值(例如,0)的情况下,可以指示不支持。
也就是说,针对4096-QAM发送,第四标识可以具有多个比特位以将RU和MRU分开进行标识。
此外,根据本公开的实施例,在发送方为接入点(例如,AP MLD)的情况下,第四标识(Tx 4096-QAM<242-tone RU support以及Tx 4096-QAM<242-tone MRU support)可以保留。
根据本公开的实施例,可以利用两个比特位分别标识RU以及MRU的情况。具体包括:Rx 4096-QAM<242-tone RU support的子域设置以及Rx 4096-QAM<242-tone MRU support子域的设置;Tx 4096-QAM<242-tone RU support的子域设置以及Tx 4096-QAM<242-tone MRU support子域的设置。将理解,第三标识和第四标识均具有两个比特位的示例仅是为了说明,而不是对本公开的限制。
此外,参照上述的实施例,第一信息可以包括在EHT PHY能力信息中,因此,表2所示的第三标识(Rx 4096-QAM<242-tone RU support以及Rx 4096-QAM<242-tone MRU support)和第四标识(Tx 4096-QAM<242-tone RU support以及Tx 4096-QAM<242-tone MRU support)可以是EHT PHY能力信息中的标识位,并且EHT PHY能力信息可以被封装在如上所述的第一消息帧中。
接下来参照表3和表4详细描述第二信息(针对1024-QAM)的实施 例。
根据本公开的实施例,第二信息可以包括第五标识和第六标识。第五标识可以指示对于第一大小的单资源单元和复合资源单元应用于1024-QAM接收的支持能力;第六标识可以指示对于第一大小的单资源单元和复合资源单元应用于1024-QAM发送的支持能力。以第一大小的单资源单元和复合资源单元为小于242-tone的资源单元作为示例进行描述,第二信息可以如下面的表3所示。
表3
Rx 1024-QAM<242-tone support Tx 1024-QAM<242-tone support
参照表3,作为示例,Rx 1024-QAM<242-tone support可以对应于第五标识,以指示对于小于242-tone的单资源单元和复合资源单元应用于1024-QAM接收的支持能力。作为示例,Tx 1024-QAM<242-tone support可以对应于第六标识,以指示对于小于242-tone的单资源单元和复合资源单元应用于1024-QAM发送的支持能力。除了QAM的类型不同之外,表3所示的第五标识和第六标识的值设置方式可以分别类似于表1所示第一标识和第二标识的值设置方式,为了简明在此省略重复的描述。根据本公开的实施例,在发送方为接入点(例如,AP MLD)的情况下,第六标识(Tx 1024-QAM<242-tone support)可以保留,这是因为可以默认AP MLD支持全功能,即,支持所有功能。
也就是说,在参照表3描述的实施例中,针对1024-QAM接收,可以仅利用第五标识(例如,具有一个比特位的Rx 1024-QAM<242-tone support)同时指示小于242-tone的单资源单元和复合资源单元的支持能力;针对1024-QAM发送,可以利用第六标识(例如,具有一个比特位的Tx 1024-QAM<242-tone support)同时指示小于242-tone的单资源单元和复合资源单元的支持能力。将理解,第五标识和第六标识具有一个比特位的示例仅是为了说明,而不是对本公开的限制。例如,第五标识和第六标识均可以具有多个比特位,以指示选择性地支持小于242-tone的资源单元之中的哪种资源单元用于1024-QAM,除了QAM的类型不同之外,上述参照表1描述的关于第一标识和第二标识具有多个比特位的实施例可以类似地应用于表3,为了简明,在此省略重复的描述。
此外,参照上述的实施例,第二信息可以包括在EHT PHY能力信息中,因此,表3所示的第五标识(Rx 1024-QAM<242-tone support)和第六标识(Tx 1024-QAM<242-tone support)可以是EHT PHY能力信息中的标识位,并且EHT PHY能力信息可以被封装在如上所述的第一消息帧中。

Figure PCTCN2021078228-appb-000002
参照表4,Rx 1024-QAM<242-tone RU support和Rx 1024-QAM<242-tone MRU support可以对应于第二信息的第七标识,也就是说,针对1024-QAM接收,第七标识可以具有多个比特位以将RU和MRU分开进行标识。在表4中,Tx 1024-QAM<242-tone RU support和Tx 1024-QAM<242-tone MRU support可以对应于第二信息的第八标识,也就是说,针对1024-QAM发送,第八标识可以具有多个比特位以将RU和MRU分开进行标识。为了描述的简明,第七标识和第八标识均可以被定义为具有两个比特位,即,表4所示的每个子域可以具有1个比特位。然而,本公开的实施例不限于此,第七标识和第八标识均可以具有更多个比特位。除了QAM的类型不同之外,表4所示的第七标识和第八标识的值设置方式可以分别类似于表2所示的第三标识和第四标识的值设置方式,为了简明在此省略重复的描述。根据本公开的实施例,在发送方为接入点(例如,AP MLD)的情况下,第八标识(Tx 1024-QAM<242-tone RU support 和Tx 1024-QAM<242-tone MRU support)可以保留。
根据本公开的实施例,可以利用两个比特位分别标识RU以及MRU的情况。具体包括:Rx 1024-QAM<242-tone RU support的子域设置以及Rx 1024-QAM<242-tone MRU support子域的设置;Tx 1024-QAM<242-tone RU support的子域设置以及Tx 1024-QAM<242-tone MRU support子域的设置。将理解,表4所示的第七标识和第八标识均具有两个比特位的示例仅是为了说明,而不是对本公开的限制。例如,第七标识中的Rx 1024-QAM<242-tone RU support可以具有多个比特位,以指示选择性地支持小于242-tone的单资源单元之中的哪种资源单元应用于1024-QAM接收。例如,第七标识中的Rx 1024-QAM<242-tone MRU support可以具有多个比特位,以指示选择性地支持小于242-tone的复合资源单元之中的哪种资源单元用于1024-QAM接收。类似地,第八标识中的Tx 1024-QAM<242-tone RU support和Tx 1024-QAM<242-tone MRU support均可以具有多个比特位。
此外,参照上述的实施例,第二信息可以包括在EHT PHY能力信息中,因此,表4所示的第七标识(Rx 1024-QAM<242-tone RU support以及Rx 1024-QAM<242-tone MRU support)和第八标识(Tx 1024-QAM<242-tone RU support以及Tx 1024-QAM<242-tone MRU support)可以是EHT PHY能力信息中的标识位,并且EHT PHY能力信息可以被封装在如上所述的第一消息帧中。
此外,在表4所示的实施例中,针对单资源单元(RU)的情况,可以重用第一消息帧的高效(HE)PHY能力信息元素来指示第七标识中的Rx 1024-QAM<242-tone RU support以及第八标识中的1024-QAM<242-tone RU support。也就是说,第七标识的多个比特位可以被分别包括在不同的能力信息元素中(例如,第七标识的Rx 1024-QAM<242-tone MRU support所对应的比特位可以被包括在EHT PHY能力信息中,而第七标识的Rx 1024-QAM<242-tone RU support所对应于的比特位可以被包括在HE PHY能力信息中。类似地,第八标识的多个比特位可以被分别包括在不同的能力信息元素中,为了简明,在此省略 重复的描述。
此外,在根据例如表1和表2将第一信息设置为支持第一大小的单资源单元和/或复合资源单元应用于4096-QAM的情况下,表3和表4所示的第二信息可以被设置为支持第一大小的单资源单元和/或复合资源单元应用于1024-QAM。也就是说,针对4096-QAM接收和发送,支持4096-QAM的标识也可以间接地标识支持1024-QAM。
此外,作为示例,第一消息帧的第一信息除了指示对于第一大小的单资源单元和/或复合资源单元应用于4096-QAM的支持能力之外,还可以同时指示对于第一大小的单资源单元和/或复合资源单元应用于1024-QAM的支持能力。在此情况下,表1所示的第一信息可以改变为表5,或者第一信息可以包括表1的信和表5的信息二者。此外,表5所示的信息可以包括在第一消息帧的EHT PHY能力信息元素中。

参照表5,Rx 4096-QAM&1024-QAM<242-tone support所对应的标识可以指示小于242-tone的资源单元(包括RU和MRU)用于4096-QAM和1024-QAM接收的支持能力。例如,如果该标识被设置为1,则指示支持所有小于242-tone的资源单元包括RU和MRU)用于4096-QAM和1024-QAM接收;如果该标识被设置为0,则指示不支持。
