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。

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是示出根据实施例的多连接下的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AP以及与AP通信的一个或多个站点(STA)构成。一个基本服务集可以通过其AP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。利用这种接入点AP,可以整合有线及无线网络。
AP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。在一些示例中,作为示例,AP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)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。
在本公开的示例实施例中,AP和STA可以支持多连接的设备,例如,可以被分别表示为AP MLD和non-AP STA MLD。为了便于描述,在下文中,主要描述一个AP与一个STA在多连接下进行通信的示例,然而,本公开的示例实施例不限于此。
在图1中,仅作为示例性的,AP MLD可以表示支持多连接通信功能的接入点,non-AP STA MLD可以表示支持多连接通信功能的站点。参照图1,AP MLD可以工作在三个连接下,如图1所示的附属AP1、AP2和AP3,non-AP STA MLD也可以工作在三个连接下,如图1所示的附属STA1、STA2和STA3。在图1的示例中,假设AP1与STA1通过对应的第一连接Link 1进行通信,类似地,AP2和AP3分别通过第二连接Link 2和第三连接Link 3与STA2和STA3进行通信。此外,Link 1至Link 3可以是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。然而,应该理解的是,图1所示的通 信场景仅是示例性的,本发明构思不限于此,例如,AP MLD可以连接到多个non-AP STA MLD,或者在每个连接下,AP可以与多个其他类型的站点进行通信。
为了提高传输效率,non-AP STA MLD可以支持通道直接链路建立(TDLS,tunneled direct link setup)功能。如图2所示,示出了根据实施例的通道直接链路建立(TDLS)的示例性示图。
参照图2,可以在第一多连接站点设备non-AP STA MLD 1与第二多连接站点设备non-AP STA MLD 2之间实现通道直接链路建立(TDLS),从而可以在他们之间直接进行通信(例如,数据的传输),而不需要经过多连接接入点设备AP MLD。将理解,虽然在图2中示出了,第一多连接站点设备non-AP STA MLD 1以及第二多连接站点设备non-AP STA MLD 2均连接到了同一多连接接入点设备AP MLD,但是本公开不限于此,例如,non-AP STA MLD 1和non-AP STA MLD 2可以分别连接到不同的AP MLD。
第一多连接站点设备non-AP STA MLD 1和第二多连接站点设备non-AP STA MLD 2中的一者可以作为TDLS的发起方来执行TDLS发现请求(TDLS discovery request),另一者可以作为TDLS的响应方来执行TDLS发现响应(TDLS discovery response),然后经过TDLS建立的过程在他们之间建立通道直接链路。例如,TDLS建立的过程可以包括:TDLS建立请求(TDLS setup request)、TDLS建立响应(TDLS setup response)以及TDLS建立确认(TDLS setup confirm)。
然而,802.11be设备支持多连接通信,现有的TDLS标准只支持单连接建立,且只支持单连接建立再进行通信,如non-AP STA MLD与AP MLD完成多连接建立后,然后如要进行TDLS通信,按照现有的标准需在每个连接下发送TDLS discovery request帧,这样TDLS连接的时间过长,不利于频谱利用。
图3是示出根据实施例的多连接下的通信方法的流程图。图3所示的通信方法可以应用于TDLS发起方。TDLS发起方可以是支持多连接通信的站点(例如,图2中的第一多连接站点设备non-AP STA MLD 1)中的任意附属站点。
参照图3,在步骤310中,在多连接中的一个连接下确定第一消息帧。根据本公开的实施例,第一消息帧可以包括用于在多连接中的至少一个连接下实现通道直接链路建立(TDLS)功能的信息(为了便于描述,在下 文称为“TDLS信息”)。
在本公开的实施例中,多连接可以是指TDLS发起方能够支持的、用于在不同频带下进行通信的多个连接(例如,图1中的Link 1、Link 2和Link 3)。仅作为描述性示例,第一消息帧可以是TDLS发现请求帧,然而本公开不限于此,其他能够用于发起TDLS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: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,TDLS发起方可以通过在第一消息帧(例如,TDLS发现请求帧)携带TDLS信息,能够在一个连接下建立至少一个连接(一个或更多个)连接下的TDLS,在下文为了便于描述,可以将这样的至少一个连接称为至少一个TDLS连接。为此,TDLS信息可以携带与将要实现TDLS的至少一个连接(至少一个TDLS连接)有关的信息。
可以通过信息元素的形式,在第一消息帧(例如,TDLS发现请求帧)中携带TDLS信息,然而,本公开不限于此,可以以任何其他可行的方式来携带TDLS信息。在下文中,为了便于描述,以信息元素的形式来描述TDLS信息。
根据本公开的实施例,第一消息帧(例如,TDLS发现请求帧)可以包括连接标识符(link identifier)信息元素,其格式可以如下面表1所示。
表1.连接标识符(link identifier)信息元素的格式
Figure PCTCN2021109052-appb-000001
参照表1,连接标识符信息元素可以包括:标识连接标识符信息元素的元素标识(Element ID)、表示连接标识符信息元素的长度信息的长度域(Length)、以及与至少一个TDLS连接对应的TDLS信息。虽然在表1中示出了与两个TDLS连接对应的TDLS信息,但是本公开不限于此,可以根据需要实现TDLS的连接的数量而不同地改变表1中的TDLS信息。
根据本公开的实施例,TDLS信息可以包括:在至少一个TDLS连接中的每个连接下的TDLS发起方的MAC地址(例如,表1中的TDLS initiator STA  MAC address1、TDLS initiator STA MAC address2)以及TDLS响应方的MAC地址(例如,表1中的TDLS responder STA MAC address1、TDLS responder STA MAC address2)。
每个附属于同一个non-AP STA MLD的STA在每个连接下具有唯一的MAC地址。可以通过携带TDLS发起方和响应方的MAC地址,来指示TDLS连接。
根据本公开的实施例,TDLS信息可以包括:与至少一个TDLS连接分别对应的基本服务集标识符或者连接标识,例如,表1中的BSSID1/Link ID1、BSSID2/Link ID2。
基本服务集标识符(BSSID)可以表示:在至少一个TDLS连接中的每个连接下的TDLS发起方所属基本服务集(BSS)的标识符。每个附属于同一个AP MLD的AP具有唯一的BSSID,与该AP连接的站点可以对应于其BSSID。换言之,基本服务集标识符(BSSID)可以表示在相应连接下与TDLS发起方关联的AP的BSSID。因此,可以通过携带至少一个基本服务集标识符(BSSID1、BSSID2)来标识至少一个TDLS连接。
连接标识(Link ID)可以具有多个比特位,以标识工作频谱、带宽/信道和/或BSSID的组合信息。可以通过携带至少一个连接标识(Link ID1、Link ID2)来标识至少一个TDLS连接。
不同的附属STA(例如,附属于不同non-AP STA MLD的附属STA)可能被分配相同的MAC地址,因此,为了能够清楚的指示TDLS的发起方和响应方以保证有效地实现TDLS功能,除了携带每个TDLS连接下的TDLS发起方的MAC地址和TDLS响应方的MAC地址,还可以携带与相应TDLS连接对应的基本服务集标识符或者连接标识。
根据本公开的实施例,在至少一个TDLS连接中的至少一部分连接下的TDLS信息可以被包括在连接标识符信息元素中。
在本公开的一个实施例中,可以如表1所示重定义连接标识符信息元素,以将至少一个TDLS连接中的所有连接所对应的TDLS信息(例如,TDLS发起方的MAC地址以及TDLS响应方的MAC地址、和/或BSSID/Link ID)携带在连接标识符信息元素中。所有TDLS连接的信息都可以携带在同一信息元素中,可以以简单的编解码方式来进行信息传输。
在本公开的一个实施例中,连接标识符信息元素可以仅包括一部分 TDLS连接的信息(例如,可以仅包括一个TDLS连接下的TDLS发起方的MAC地址以及TDLS响应方的MAC地址、和/或BSSID/Link ID),而其他TDLS连接的信息可以携带在第一消息帧的其他位置中。例如,第一消息帧可以包括多连接(ML)信息元素,在至少一个TDLS连接中的至少一部分连接下的TDLS信息可以被包括在第一消息帧的多连接信息元素中。也就是说,部分TDLS连接的信息可以携带在连接标识符信息元素,部分TDLS连接的信息可以携带在ML信息元素中。在此情况下,当第一消息帧以TDLS发现请求帧来实现时,其可以具有下面表2所示的格式。
表2.TDLS发现请求帧的定义
Figure PCTCN2021109052-appb-000002
在表2中,Order(顺序)可以标识各个信息域(Information)在TDLS发现请求帧中的顺序。Category(类别)域可以标识各种管理动作的机制,例如,当其被设置为特定值(例如但不限于,12)时,可以标识TDLS机制。TDLS action(TDLS动作)域可以被设置为各种值以区分不同的TDLS动作,例如,当其被设置为特定值(例如,但不限于“10”)时,可以标识TDLS发现请求。Dialog token(对话令牌)域可以用于将TDLS发现响应帧与TDLS发现请求帧进行匹配。连接标识符信息元素/用于多连接的连接标识符信息元素(Link identifier element/Link identifier element for multi-link)可以如上所述包括部分TDLS连接的信息(例如,一个TDLS连接的信息)。Multi-band(多带宽)域可以根据源语的设置选择性地存在。ML信息元素可以如上所述包括部分TDLS连接的信息(例如,除了连接标识符信息元素所包括的部分TDLS连接的信息之外的其他TDLS连接的信息),例如,可以在ML信息元素的per-STA配置信息(per-STA profile)中至少包括相应TDLS连接下的TDLS响应方的MAC地址和/或连接标识(Link ID),然而本公开不限于 此,还可以包括TDLS发起方的MAC地址和/或连接标识(Link ID)等。
在表2中,连接标识符信息元素/用于多连接的连接标识符信息元素(Link identifier element/Link identifier element for multi-link)可以保持原有格式,例如,包括一个TDLS连接的信息,而其他TDLS连接的信息可以携带在ML信息元素中。这样的设计可以增加系统的兼容性和灵活性。
以表1和表2所示的连接标识符信息元素和/或ML信息元素携带的TDLS信息仅是示例性的,本公开不限于此。例如,TDLS信息可以具有不同于表1和表2所示的内容。例如,在本公开的一个可选实施例中,TDLS信息可以包括:AP MLD MAC地址(AP MLD MAC address)、连接位图标识(Link bitmap)、TDLS发起方多连接站点设备的MAC地址(TDLS initiator non-AP STA MLD MAC address)和TDLS响应方多连接站点设备的MAC地址(TDLS responder non-AP STA MLD address)。在此情况下,TDLS信息可以携带在具有如下面的表3所示的格式的连接标识符信息元素中。
表3.连接标识符信息元素的格式
Figure PCTCN2021109052-appb-000003
在表3中,连接位图标识(Link bitmap)可以被设置为特定值(例如但不限于,“1”)以标识要建立TDLS连接。
通过以如表3所示的连接标识符信息元素携带TDLS信息,可以在连接到同一AP MLD的两个non-AP STA MLD(如图2所示的non-AP STA MLD1和non-AP STA MLD2)之间建立TDLS连接,并且所建立的TDLS连接可以对应于两个non-AP STA MLD所支持的多个连接。通过表3所示的TDLS信息,可以快速地、更简单地实现TDLS连接。
表3所示的格式仅是示例性的,而不是对本公开的限制,可以对表3进行各种变形。例如,表3中可以包括:多个AP MLD MAC地址、多个TDLS发起方non-AP STA MLD MAC地址以及多个TDLS响应方non-AP SAT MLD MAC地址。换言之,可以在连接到不同AP MLD的non-AP STA MLD之间建立TDLS连接。此外,可以理解的是表1至表3所示的每一个元素都是独立存在的,这些元素被示例性的列在同一张表格中,但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值,是不依 赖于表格中任何其他元素值。因此本领域内技术人员可以理解,本公开表格中的每一个元素的取值都是一个独立的实施例。
继续参照图3,在步骤320中,可以发送第一消息帧。附属于同一个non-AP STA MLD的任意STA可以在任一连接下发送第一消息帧(TDLS发现请求帧)。例如,可以在步骤310中的确定第一消息帧的连接下发送第一消息帧,然而本公开不限于此,可以在不同于步骤310中的确定第一消息帧的连接的其他连接下发送第一消息帧。
根据本公开的实施例的多连接下的通信方法,在non-AP STA MLD与AP MLD完成了多连接建立之后,如果需要在多连接下进行TDLS通信,则不需要在每个连接下发送TDLS发现请求帧,而是可以在一个连接下通过一个TDLS发现请求帧建立至少一个连接(优选地,多个连接)下的TDLS,从而缩短TDLS连接建立的时间,实现频谱的有效利用,以及利于设备省电。
图4是示出根据实施例的多连接下的另一通信方法的流程图。图4所示的通信方法可以应用于TDLS响应方。TDLS响应方可以响应于图3的第一消息帧(TDLS发现请求帧)而与TDLS发起方进行TDLS通信的站点(例如,图2中的第二多连接站点设备non-AP STA MLD 2)中的任意附属站点)。在一个实施例中,如图2所示,TDLS响应方可以与TDLS发起方连接到同一AP MLD;在另一实施例中,TDLS响应方可以与TDLS发起方连接到不同的AP MLD。
参照图4,在步骤410中,在多连接中的一个连接下接收第一消息帧,其中,第一消息帧可以包括用于在多连接中的至少一个连接下实现通道直接链路建立(TDLS)功能的信息,即,TDLS信息。
根据本公开的实施例,TDLS信息可以包括:与至少一个连接分别对应的基本服务集标识符或者连接标识。
根据本公开的实施例,TDLS信息包括:在至少一个连接中的每个连接下的TDLS发起方的MAC地址以及TDLS响应方的MAC地址。
根据本公开的实施例,基本服务集标识符表示:在至少一个连接中的相应连接下的TDLS发起方所属基本服务集的标识符。
根据本公开的实施例,第一消息帧包括连接标识符信息元素,其中,在至少一个连接中的至少一部分连接下的TDLS信息被包括在连接标识符信息元素中。
根据本公开的实施例,第一消息帧包括多连接信息元素,其中,在至 少一个连接中的至少一部分连接下的TDLS信息被包括在第一消息帧的多连接信息元素中。
图4中的第一消息帧、TDLS信息、连接标识符信息元素、多连接信息元素可以类似于参照图3以及表1至表3描述的实施例,在此省略重复的描述以避免冗余。
在步骤420中,可以基于第一消息帧执行通信操作。例如,TDLS响应方可以基于第一消息帧中携带的TDLS信息与TDLS发起方在相应连接下建立并开始TDLS通信操作。
图5是示出根据本公开的实施例的通信装置500的框图。
参照图5,通信装置500可以包括处理模块510和收发模块520。图5所示的通信装置可以应用于TDLS发起方或者TDLS响应方。
在图5所示的通信装置500应用于TDLS发起方的情况下,处理模块510可以被配置为:在多连接中的一个连接下确定第一消息帧,其中,第一消息帧包括用于在多连接中的至少一个连接下实现通道直接链路建立(TDLS)功能的信息;收发模块520可以被配置为:发送第一消息帧。在此情况下,通信装置500可以执行参照图3所描述的通信方法,并且第一消息帧以及其中包括的信息可以类似于参照表1至表3描述的实施例,在此省略重复的描述以避免冗余。
在图5所示的通信装置应用于TDLS响应方的情况下,收发模块520可以被配置为:在多连接中的一个连接下接收第一消息帧,其中,第一消息帧包括用于在多连接中的至少一个连接下实现通道直接链路建立(TDLS)功能的信息;处理模块510可以被配置为:基于第一消息帧控制通信操作的执行。在此情况下,通信装置500可以执行参照图4所描述的通信方法,并且第一消息帧以及其中包括的信息可以类似于参照表1至表3描述的实施例,为了简明,在此省略重复的描述。
此外,图5所示的通信装置500仅是示例性的,本公开的实施例不限于此,例如,通信装置500还可以包括其他模块,例如,存储器模块等。此外,通信装置500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。
根据本公开的实施例的多连接下的通信方法和通信装置能够在多连 接通信中应用TDLS机制,提高频谱利用率。

应该理解的是,虽然附图的流程图中的各个步骤按照箭头的指示依次显示,但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明,这些步骤的执行并没有严格的顺序限制,其可以以其他的顺序执行。此外,附图的流程图中的至少一部分步骤可以包括多个子步骤或者多个阶段,这些子步骤或者阶段并不必然是在同一时刻执行完成, 而是可以在不同的时刻执行,其执行顺序也不必然是依次进行,而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
虽然已经参照本公开的某些实施例示出和描述了本公开,但是本领域技术人员将理解,在不脱离本公开的范围的情况下,可以在形式和细节上进行各种改变。因此,本公开的范围不应被限定为受限于实施例,而是应由所附权利要求及其等同物限定。
