在本公开中使用的术语和词语不限于书面含义,而是仅被发明人所使用,以能够清楚和一致的理解本公开。因此,对于本领域技术人员而言,提供本公开的各种实施例的描述仅是为了说明的目的,而不是为了限制的目的。
应当理解,除非上下文另外清楚地指出,否则这里使用的单数形式“一”、“一个”、“所述”和“该”也可以包括复数形式。应该进一步理解的是,本公开中使用的措辞“包括”是指存在所描述的特征、整数、步骤、操作、元件和/或组件,但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。
将理解的是,尽管术语“第一”、“第二”等在本文中可以用于描述各种元素,但是这些元素不应受这些术语的限制。这些术语仅用于将一个元素与另一个元素区分开。因此,在不脱离示例实施例的教导的情况下,下面讨论的第一元素可以被称为第二元素。
应该理解,当元件被称为“连接”或“耦接”到另一元件时,它可以直接连接或耦接到其他元件,或者也可以存在中间元件。此外,这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的术语“和/或”或者表述“……中的至少一个/至少一者”包括一个或多个相关列出的项目的任何和所有组合。
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(或称为站点(STA)设备)构成。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,也是无线网络的接入设备。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,站点(STA)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设备与三个站点(STA)设备(STA1、STA2、STA3)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STA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设备和站点(STA)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。
non-AP STA MLD可以支持两种模式为EMLSR(增强型多连接单无线通信:enhanced–multilink single radio)及EMLMR(增强型多连接多无线通信:enhanced–multilink multi-radio),但non-AP STA MLD在某一时刻仅能保持一种模式。EMLSR是指non-AP STA MLD在某一时刻只能在一个连接下与AP MLD通信;EMLMR是指non-AP STA MLD在某一时刻在多个连接下与AP MLD通信。
在AP MLD与non-AP STA MLD之间进行多连接建立/关联过程中, non-AP STA MLD仅是在基本多连接(ML)信息元素中标识了其支持EMLSR和/或EMLMR,但具体在某一时刻在哪些连接下支持EMLSR或EMLMR,却没有做出明确的规定,所以需进行增强。
图2是示出根据实施例的通信方法的流程图。图2所示的通信方法可以应用于支持多连接通信的站点,即,non-AP STA MLD。
参照图2,在步骤210中,可以确定第一消息帧。在步骤220中,可以发送第一消息帧。
在本公开的实施例中,第一消息帧可以是,例如但不限于,增强型多连接操作模式通知帧(EML operating mode notification frame)。第一消息帧(增强型多连接操作模式通知帧)用于指示non-AP STA MLD的附属STA改变其操作模式。然而,本公开不限于此,能够携带指示操作模式的其他类型的帧也是可行的。
在本公开的实施例中,确定第一消息帧的方式可以有很多种,例如:可以根据以下的至少一种情况来生成第一消息帧:信道状态、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,还可以从外部设备获取该第一消息帧,对此本公开实施例不作具体限制。
根据本公开的实施例,所述第一消息帧包括:用于指示将要保持的操作模式的标识信息,其中,该标识信息对应于用于标识所述操作模式适用的连接的连接信息。
在本公开的一些示例实施例中,该标识信息可以被包括在第一消息帧中。
为了描述的方便,在下文中,以增强型多连接操作模式通知帧为例来描述第一消息帧。例如,标识信息和连接信息可以被携带在第一消息帧的行动域(Action field)中,如面的表1所示的格式。
表1.增强型多连接操作模式通知帧行动域
Order(顺序) Information(信息)
1 Category(类别)
2 EHT Action(EHT行动)
3 Dialog Token(对话令牌)
4 EML Control(EML控制)
5 Link set(连接组)
参照图1,顺序(Order)表示各个信息(Information)在第一消息帧中的位置顺序。仅作为描述性的示例,第一消息帧可以包括类别域、EHT行动域、对话令牌域、EML控制域、连接组域等。然而,本公开不限于此,可以从表1省略部分信息,或者可以包括更多其他信息。
表1中的“EML控制(EML Control)”域可以作为第一消息帧中包括的用于指示将要保持的操作模式的标识信息的示例。例如,EML控制域可以具有如下面的表2所示的格式。
表2.EML控制域的格式
Figure PCTCN2021112875-appb-000001
第一消息帧中包括的用于指示将要保持的操作模式的标识信息可以通过表2中的EMLSR模式子域和EMLMR模式子域来标识。
例如,如果EMLSR模式子域被设置为特定值(例如但不限于,1),则指示以EMLSR操作模式运行。在此情况下,EMLMR模式子域可以被位置为“0”。
例如,如果EMLMR模式子域被设置为特定值(例如但不限于,1),以指示以EMLMR操作模式运行。在此情况下,EMLSR模式子域可以被位置为“0”。
表1中的“连接组(Link set)”域可以作为第一消息帧中包括的用于标识所述操作模式适用的连接的连接信息的示例。换言之,第一消息帧中的连接信息可以表示连接组信息。该连接组信息包含多个比特位,并且多个比特位分别对应于non-AP STA MLD支持的多个连接标识信息。
根据本公开的实施例,在连接组信息(Link set)的至少一个比特位被设置为特定值的情况下,连接组信息(Link set)可以表示在与至少一个比特位对应的至少一个连接下保持由第一消息帧中的标识信息所指示的操作模式。
例如,如果non-AP STA MLD最大支持16个天线,则连接组信息(Link set)的长度可以为2个字节(16比特),并且如果连接组信息(Link set)的某个比特位或者某些比特位被设置为特定值(例如但不限于,1),则标识其为EMLSR或EMLMR连接,即,在被设置为特定值的连接下以表2 所定义的操作模式进行工作。
由于non-AP STA MLD在某一时刻只能保持一种模式,因此只需要一个Link set信息域,例如,在EML控制域中的EMLSR模式比特位或EMLMR模式比特位设置为“1”,则重用Link set信息域。例如,结合表1和表2,如果EMLMR模式子域被设置为“1”,EMLSR模式子域被设置为“0”,并且连接组信息被设置为“0000 0000 0000 0011”,则可以标识在与连接组信息中的最低两位对应的连接下将要保持EMLMR操作模式。
虽然在表2中示出了,连接信息可以利用Link set的方式来进行表示,但是本公开不限于此。例如,连接信息可以表示连接标识(Link ID)。即,表1中的顺序为“5”的Link set可以利用一个或多个Link ID来替换。每个连接标识(Link ID)可以具有多个比特位,以标识工作频谱、带宽/信道以及BSSID(基本服务集标识符,basis service set identifier)的组合信息。
连接信息中所标识的连接(Link set或者Link ID)可以是业务标识(TID)所映射到的连接。也就是说,可以在连接信息中所标识的连接(Link set或者Link ID)进行由TID标识的业务传输。
表1和表2所示的实施例可以使得non-AP STA MLD灵活地选择各个连接下的操作模式。例如,可以根据某些连接的负载均衡(load balance)等因素考量各个连接下的操作模式,从而确定第一消息帧中包括的标识信息和连接信息。
在表1和表2所示的实施例中,第一消息帧中的用于指示将要保持的操作模式的标识信息以及用于标识该操作模式适用的连接的连接信息可以位于第一消息帧的不同域中,然而本公开不限于此。
根据本公开的实施例,连接信息可以与用于指示将要保持的操作模式的标识信息位于第一消息帧的相同域中。例如,二者可以位于表1中的EML控制域中,在此情况下,EML控制域可以具有如下面的表3所示的格式。
表3.EML控制域的格式
Figure PCTCN2021112875-appb-000002
表3中的EMLSR模式子域和EMLMR模式子域可以类似于上述参照表2描述的实施例,为了简明,在此省略重复的描述。
表3中的“默认使用(Default use)”可以作为连接信息的示例。在该示例中,连接信息(Default use)可以具有单个比特位,用于表示由EMLSR模式子域和EMLMR模式子域所指示的操作模式适用于non-AP STA MLD标识的所有连接。
在EML控制域中利用一个比特位来标识EMLSR模式或EMLMR模式适用于在关联过程中或多连接建立过程中non-AP STA MLD标识的所有连接。例如,如果non-AP STA MLD与AP MLD在关联过程中或多连接建立过程中建立了两个连接或者更多个连接(例如,16个连接),并且默认使用(Default use)被设置为特定值(例如,1),则可以标识由表3中的EMLSR模式子域或EMLMR模式子域标识的操作模式可以适用于建立的所有的两个连接或者更多个连接(例如,16个连接)。在此情况下,可以从表1中省略Link set后Link ID,从而精简第一消息帧中携带的信息。
将理解,表3所示的实施例进行说明性的,本公开不限于此。例如,可以在表3所示的EML控制域中携带连接组(Link set),用于指示所建立的所有连接中的部分连接。
non-AP STA MLD可以将第一消息帧发送到AP MLD,如果AP MLD同意第一消息帧中设置的关于操作模式的标识信息和操作模式所适用的连接(连接信息),则non-AP STA MLD可以从AP MLD接收相应的反馈帧(或确认帧);如果AP MLD不同意第一消息帧中的设置,则non-AP STA MLD可以从AP MLD接收其推荐的操作模式和连接信息。也就是说,可以在non-AP STA MLD与AP MLD之间具体协商操作模式和所使用的连接。
在本公开的其他示例实施例中,标识信息可以不被包括在第一消息帧中。即,可以从第一消息帧省略连接信息(例如,从表1省略Link set,从表3省略Default use,而仅在第一消息帧(EML operating mode notification frame)中包含用于指示将要保持的操作模式的标识信息(例如,表2和表3中的EMLSR mode和EMLMR mode)。也就是说,在第一消息帧中可以不包含用于指示具体哪些连接将要保持相应的操作模式。
作为一个示例,连接信息可以被包括在多连接建立过程中传输的能力信息中。
例如,在操作模式为EMLMR模式的情况下,连接信息可以表示从多连接信息元素中的EML能力信息所标识的多个空间流中选择的连接。具体地 说,在EMLMR模式的情况下,可以使用(或参考)在多连接建立过程中的多连接信息元素中的EML能力信息(EML capabilities)子域中的EMLMR Rx NSS及EMLMR Tx NSS中的信息位(其可以分别标识接收方和发送方支持的连接数(空间流数量)),具体在哪些连接下进行EMLMR模式可以基于产品(例如,接收方和发送方的配置)来实现。例如,EML能力信息子域可以具有如下面的表4所示的格式。在该实施例中,可以从多连接建立过程中的表4所示的EMLMR Rx NSS及EMLMR Tx NSS标识的多个连接中选择合适的连接,以在EMLMR模式下进行通信。
表4.EML能力信息子域的格式
Figure PCTCN2021112875-appb-000003
例如,在操作模式为EMLSR模式的情况下,连接信息可以表示从EHT能力信息元素中的信息位所标识的调制与编码策略方式和空间流组中选择的连接。具体地说,在EMLSR模式的情况下,使用在多连接建立的过程中EHT能力信息元素中的信息位(Supported EHT-MCS and NSS Set(支持的EHT-MCS和NSS组)域)所标识的连接信息。即,可以从如下面的表5所标识的连接(每个连接对应每个MCS(调制与编码策略)方式)中选择合适的连接,以在EMLSR模式下进行通信,而怎样去选择哪些连接可以基于产品来实现。
表5.EHT-MCS映射(20MHz-Only STA)子域和基本EHT-MCS和NSS组(Basic EHT-MCS and NSS Set)域
Figure PCTCN2021112875-appb-000004
表5示出了在20MHz带宽下所支持的EHT-MCS和NSS组,其可以具体指示设备支持的用于发送和用于接收的EHT-MCS 0-13的组合以及空间流Nss的数量。然而,本公开不限于此,还可以包括80MHz带宽下、160MHz带宽下和/或320MHz带宽下的相似的信息。
多连接信息元素中的EML能力信息子域以及EHT能力信息元素中的信 息位(Supported EHT-MCS and NSS Set)可以在多连接过程中进行传输,例如,由AP MLD携带在信标帧、(重)关联响应帧、探测响应帧中,或者由non-AP STA MLD携带在(重)关联请求帧、探测请求帧中。
在本公开的其他示例实施例中,除了使用从表4和表5所示的信息来选择合适的连接之外,连接信息还可以是基于以下情况中的至少一种情况下被确定的:增加或删除的连接;或者non-AP STA MLD的站点将要切换到的基本服务集中的连接。
例如,在确定连接信息时,可以考虑从AP MLD删除的BSS中的连接、增加到AP MLD的BSS中的连接。例如,如果non-AP STA MLD处于删除或者增加BSS的情况,则可以也可以从所删除的连接之外的连接(即,所剩余的连接)、所增加的连接中选择合适的连接来进行相应操作模式下的通信。
此外,non-AP STA MLD可能存在切换到其他BSS的情况(例如,在与non-AP STA MLD关联的AP MLD内部进行BSS切换),在此情况下,例如,在确定连接信息时,还可以考虑所切换到的BSS中的连接,即,也可以从所切换到的BSS中的连接选择合适的连接来进行相应操作模式下的通信。
此外,将理解,可以在non-AP STA MLD标识的多个连接中的任意连接下执行图2中的步骤210和220。例如,参照图1,可以在Link 1下确定以及发送第一消息帧,并且第一消息帧中携带的信息可以指示本连接(Link 1)和/或其他连接(Link 2、Link3等)的操作模式。
图3是示出根据本公开的另一实施例的通信方法的流程图。图3所示的通信方法可以应用于支持多连接通信的接入点,即,AP MLD。
参照图3,在步骤310中,可以接收第一消息帧。其中,第一消息帧可以包括:用于指示将要保持的操作模式的标识信息,其中,标识信息对应于用于标识该操作模式适用的连接的连接信息。
根据本公开的实施例,该连接信息可以被包括在第一消息帧中,并且表示连接组信息,其中,该连接组信息包含多个比特位,多个比特位分别对应于与AP MLD关联的non-AP STA MLD支持的多个连接标识信息。例如,在该连接组信息的至少一个比特位被设置为特定值的情况下,该连接组信息表示在与至少一个比特位对应的至少一个连接下保持该操作模式。例如,该标识信息和所述连接信息位于该第一消息帧的不同域中。在 此情况下,第一消息帧、连接信息、标识信息可以类似于上述参照表1和表2描述的实施例,在此省略重复的描述以避免冗余。
根据本公开的实施例,该连接信息具有单个比特位,用于表示该操作模式适用于与AP MLD关联的non-AP STA MLD标识的所有连接。例如,该标识信息和该连接信息位于第一消息帧的相同域中。在此情况下,第一消息帧、连接信息、标识信息可以类似于上述参照表1和表3描述的实施例,在此省略重复的描述以避免冗余。
在步骤320中,可以基于第一消息帧执行通信操作。例如,如果AP MLD同意接收到的第一消息帧中设置的关于操作模式的标识信息和操作模式所适用的连接(连接信息),则AP MLD可以向non-AP STA MLD发送相应的反馈帧(或确认帧);如果AP MLD不同意第一消息帧中的设置,则AP MLD可以向non-AP STA MLD发送推荐的操作模式和连接信息。
此外,根据本公开的实施例,该连接信息可以被包括在多连接建立过程中传输的能力信息中。例如,在操作模式为EMLMR模式的情况下,该连接信息可以表示从多连接信息元素中的EML能力信息所标识的多个空间流中选择的连接;在操作模式为EMLSR模式的情况下,该连接信息可以表示从EHT能力信息元素中的信息位所标识的调制与编码策略方式和空间流组中选择的连接。
此外,根据本公开的实施例,该连接信息可以是基于以下情况中的至少一种情况下被确定的:增加或删除的连接;或者non-AP STA MLD的站点将要切换到的基本服务集中的连接。
图4是示出了根据实施例的通信装置400的框图。图4所示的通信装置400可以应用于non-AP STA MLD或者AP MLD。
在图4所示的通信装置400应用于non-AP STA MLD的情况下,处理模块410可以被配置为确定第一消息帧,其中,第一消息帧包括:用于指示将要保持的操作模式的标识信息,其中,标识信息对应于用于标识该操作模式适用的连接的连接信息;收发模块420可以被配置为发送第一消息帧。也就是说,在此情况下,通信装置400可以执行参照图2描述的通信方法,并且第一消息帧、连接信息、标识信息可以类似于参照表1至表5描述的实 施例,为了简明,在此省略重复的描述。
在图4所示的通信装置400应用于AP MLD的情况下,收发模块420可以被配置为接收第一消息帧,其中,第一消息帧包括:用于指示将要保持的操作模式的标识信息,其中,标识信息对应于用于标识该操作模式适用的连接的连接信息;处理模块410可以被配置为基于该第一消息帧控制通信操作的执行。也就是说,在此情况下,通信装置400可以执行参照图3所描述的通信方法,并且第一消息帧、连接信息、标识信息可以类似于参照表1至表5描述的实施例,为了简明,在此省略重复的描述。
此外,图4所示的通信装置400仅是示例性的,本公开的实施例不限于此,例如,通信装置400还可以包括其他模块,例如,存储器模块等。此外,通信装置400中的各个模块可以组合成更复杂的模块,或者可以划分为更多单独的模块。
