下面将结合附图详细描述本公开的实施方式。
图1是示出根据本公开的示例实施例的多连接下的切换通信的示图。
在无线局域网中,一个基本服务集(BSS)可以由接入点(AP:Access Point)以及与AP通信的一个或多个设备(non-AP STA,在本文中可以被称为“站点(STA:Station)”)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,也是无线网络的核心。AP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,non-AP STA(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(Access Point)和non-AP STA(Station)可以是支持多连接通信的设备,例如,可以被分别表示为AP MLD和non-AP STA MLD(multi-link device)。为了便于描述,在下文中,主要描述一个AP MLD与一个non-AP STA MLD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的接入点,non-AP STA MLD可以表示支持多连接通信的站点。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下的连接等或者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可以与多个其他的站点进行通信。
此外,虽然在图1中示出了第一连接Link 1至第三连接Link 3均属于同一个AP MLD,但是本公开的实施例不限于此,例如,第一连接Link 1至第三连接Link 3可以图1所示的AP MLD与其他AP MLD共享的连接。
此外,虽然在图1中示出了AP MLD与non-AP STA MLD之间的多个连 接的数量为三个,但是本公开的实施例不限于此,它们之间可以存着更多或更少的连接。
参照图1,non-AP STA MLD可以使用附属的站点(例如,STA1至STA3中的任意一个)的电源状态来动态改变其运行的连接。图1可以是示出具有将所有通信标识(TID:traffic identifier)映射到所有建立的连接的默认映射的单无线通信non-AP STA MLD的操作示例,其中,non-AP STA MLD的STA 1在Link 1上的操作改变为STA2在Link 2上的操作。TID可以对应不同的上层业务及QoS(服务质量:Quality of Service)需求。
当在Link1上操作时,non-AP STA MLD的STA1可以使用激活模式(active mode)或具有唤醒状态(awake state)的省电模式(power save mode)来从AP MLD获取业务单元(BU:buffer unit),并且可以使用具有休眠状态(doze state)的省电模式来节能。在此情况下,STA2和STA3可以处于休眠状态。
当在Link2上操作时,non-AP STA MLD的STA2可以使用激活模式或具有唤醒状态的省电模式来从AP MLD获取业务单元,并且可以使用具有休眠状态的省电模式来节能。在此情况下,STA1和STA3可以处于休眠状态。
此外,将理解,虽然图1中示出了non-AP STA MLD的附属站点从Link1切换到Link2的操作,但是本公开的实施例不限于此,例如,AP MLD的附属接入点也可以执行切换操作。
图1是示出了从Link1切换到Link2之后站点STA2的操作,下面将描述例如从Link1切换到Link2的动态切换的实施例。
图2是示出根据本公开的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设备,例如,AP MLD或non-AP STA MLD。图2所示的通信方法可以是由发送方执行的操作。发送方可以是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。
参照图2,在步骤210中,可以确定第一消息帧,其中,第一消息帧 包括指示动态连接切换的信息。根据本公开的实施例,第一消息帧为连接切换帧、数据帧或关联帧,然而,本公开不限于此,可以用于传输动态连接切换信息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: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,指示动态连接切换的信息可以是根据以下至少一项确定的:
多个连接中的每个连接下的接入时延时间;
每个连接下的负载情况;
将要发送的业务的需求。
在一个实施例中,多个连接中的每个连接下的接入时延时间可以指每个连接的接入时延时间,还可以指多个连接的平均接入时延时间。例如,每个连接下的负载情况可以指利用该连接进行通信的站点的数量。例如,将要发送的业务的需求可以指将要发送的业务的QoS的需求,例如,对传输业务的时延需求。
根据本公开的实施例,指示动态连接切换的信息可以包括将要切换到的连接的信息,例如,将要切换的连接的连接标识。此外,指示动态连接切换的信息还可以包括当前连接的信息以及连接切换的时延信息中的至少一项。例如,当前连接的信息可以指当前连接的连接标识,连接切换的时延信息可以指执行连接切换的时延值。更具体地,执行连接切换的时延值可以表示在接收到指示连接切换的帧之后,经过该时延值之后再进行切换操作。根据本公开的实施例,可以不包括该时延信息,或者该时延信息被设置为特定值(例如,0),从而指示在没有时延的情况下执行连接切换。根据本公开的实施例,该时延信息被设置为其他值,例如,5us,从而指示在接收到第一消息帧之后间隔5us之后执行连接切换。
结合图1,当从Link1切换到Link2时,指示动态连接切换的信息可 以包括将要切换到的连接Link2的连接标识,可选地,还可以包括当前连接Link1的连接标识和从Link1切换到Link2的时延值中的至少一项。
根据本公开的实施例,可以以信令形式将指示动态连接切换的信息携带在第一消息帧中。例如,第一消息帧可以是连接切换帧,并且指示动态连接切换的信息可以以以下面的表1所示的信息元素的形式包括在第一消息帧(即,连接切换帧)中。
表1.
Figure PCTCN2021072547-appb-000001
可以理解的是表格1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1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。
在表1中,元素标识(Element ID)和长度(Length)可以指示与该信息元素有关的标识及长度。当前连接标识(Current link ID)可以对应于当前连接的信息,切换连接标识(Transition link ID)可以对应于将要切换到的连接的信息,切换延时(Transition delay)可以对应于连接切换的时延信息。
根据本公开的实施例,第一消息帧还可以包括标识发送第一消息帧的设备处于节能状态的信息。例如,可以在第一消息帧(例如,连接切换帧)的MAC帧头中携带该信息。例如,标识发送第一消息帧的设备处于节能状态的信息可以对应于MAC帧头的电源管理(power management)域的PS(节能:power save)比特位。例如,可以通过将PS比特位设置为特定值(例如,1),从而在接收到针对第一消息帧的确认帧的情况下,发送第一消息帧的设备可以处于节能状态。换言之,如果接收到该确认帧,则表示接收到第一消息帧的接收方将会根据第一消息帧中的指示动态连接切换的信息来执行连接切换,因此当前连接下的发送方可以处于节能状态。此外,虽然在此描述了标识发送第一消息帧的设备处于节能状态的信息未 被标识在表1所示的信息元素中(即,标识发送第一消息帧的设备处于节能状态的信息与指示动态连接切换的信息被标识在第一消息帧的不同位置处),但是本公开的实施例不限于此,其他信息标识的方式可以包括在本公开的范围内。
根据本公开的实施例,指示动态连接切换的信息可以包括在第一消息帧的MAC帧头中,例如,可以在数据帧或关联帧的MAC帧头中携带指示动态连接切换的信息。在一个实施例中,发送方设备可以在传输的MPDU(MAC协议数据单元:MAC Protocol Data Unit)的MAC帧头中携带指示动态连接切换的信息。具体地,可以重利用MAC帧头中的控制域来标识将要进行切换的信息,例如,可以以表1所示的信息元素的形式来携带指示动态连接切换的信息,或者第一消息帧(例如,MAC帧头的控制域)可以携带将要切换到的连接的信息,此外,还可以携带当前连接的信息以及连接切换的时延信息中的至少一项。
在一个实施例中,可以在第一消息帧的MAC帧头中仅携带将要切换到的连接的信息。例如,第一消息帧(例如,MAC帧头)可以包括多个连接的连接组(Link set)信息,其中,连接组信息中的与将要切换到的连接相对应的比特被设置为第一值(例如,1),以指示切换到该连接。结合图1,可以利用具有三个比特位的连接组来表示三个连接(Link1至Link2),将要切换到的连接为Link2,例如,当连接组被表示为010时,可以指示将要切换到Link2。将理解,虽然在该实施例中,第一值被示出为1,但是本公开不限于此,其他值(例如,0)也是可行的。此外,将理解,连接组的这种方式也可以应用于表1所示的信息元素中,即,表1中的当前连接标识(Current link ID)和切换连接标识(Transition link ID)可以利用连接组的方式来替换。
根据本公开的实施例,可以在传输连接中标识将要切换的连接。结合图1,传输连接可以对应于当前连接Link1,将要切换的连接可以对应于将要切换到的连接Link2。
根据本公开的实施例,可以根据连接的平均接入时延或连接的负载情况,在传输连接生成连接切换帧,其中,连接切换帧中携带将要切换的连 接信息,例如,表1所示的信息元素;并且传输连接在切换完成后(即,接收到确认帧后)处于PS状态,例如,可以将切换消息帧的MAC帧头的电源管理域的PS比特位设置为“1”,标识其处于PS状态,当接收到确认帧后,传输连接下的发送方(例如,站点)可以休眠。可选地,在表1所述的信息元素中可以携带切换的时延值,但是时延值一般可以设置为“0”以指示在没有时延的情况下进行切换。在另一实施例中,AP也可以配置连接切换的时延值,作为示例,时延值可以被配置为5us。例如,当站点作为发送第一消息帧的发送方时,可以将切换的时延值默认地设置为0,或者可以从AP另外地接收配置的时延值。例如,AP作为发送第一消息帧的发送方时,AP可以直接在表1所示的信息元素中配置时延值。
根据本公开的实施例,传输连接的设备可以在传输的MPDU的MAC帧头中携带将要切换的传输连接指示,具体为重利用A-control域标识要该设备要进行连接切换,具体可以为表1所示的信息元素的格式,或者如上所述的连接组的格式。
在步骤220中,可以发送第一消息帧。当发送方向接收方发送了第一消息帧时,发送方可以接收来自接收方的确认帧。当发送方接收到确认帧时,可以确定接收方将执行连接切换操作,并且可以将当前连接处于休眠状态。
图2所示的通信方法仅是示例性的,本公开的实施例不限于此。在一个实施例中,图2所示的通信方法还可以包括以下至少一项:发送支持多连接操作的能力信息、发送支持动态连接切换的能力信息。多连接操作可以指示增强型多连接多无线通信(EMLMR:enhanced multi-link multi-radio)或增强型多连接单无线通信(EMLSR:enhanced multi-link single radio)。在发送方仅发送支持多连接操作的能力信息的情况下,发送方支持多连接操作可以隐含地标识发送方支持动态连接切换。也就是说,支持多连接操作的能力信息可以指示支持动态连接切换的能力信息。
根据本公开的实施例,站点与AP可以在初始关联的过程中,携带其支持多连接操作的能力信息值,具体为EMLMR或EMLSR;或者携带支持动态连接切换能力信息值,或者支持多连接操作隐含地标识其支持动态连接切换。
图3是示出根据本公开的示例实施例的另一通信方法的流程图。图3的流 程图可以是在接收方进行的操作,即,与图2所示的发起方的操作相对应的操作。
参照图3,在步骤310中,可以接收第一消息帧,其中,第一消息帧包括指示动态连接切换的信息。
类似于上文所述的实施例,指示动态连接切换的信息可以是根据以下至少一项确定的:多个连接中的每个连接下的接入时延时间;每个连接下的负载情况;将要发送的业务的需求。
根据实施例,指示动态连接切换的信息可以包括将要切换到的连接的信息,此外,还可以包括当前连接的信息以及连接切换的延时信息中的至少一项。将理解,第一消息帧以及指示动态连接切换的信息可以类似于图2的步骤210的描述,为了简明,在此省略重复的描述。
在步骤320中,可以基于第一消息帧,执行连接的切换操作。例如,根据第一消息帧中的信息,经过连接切换的时延信息所指示的时延时间之后,从当前连接切换到将要切换到连接。
在步骤330中,可以发送针对第一消息帧的确认帧,以使得发送方在接收到确认帧后将当前连接所对应的设备设置为休眠状态。
可以理解的是,图3所示的通信方法的流程图仅是示例性的,并且各个步骤可以按照与图3所示的顺序不同的顺序来执行,或者各个步骤可以串行或者并行地执行。
在一个实施例中,虽然未示出,但是图3所示的通信方法还可以包括:接收能力信息。例如,在接收方和发送方的关联阶段中,接收方可以接收从发送方发送的支持多连接操作的能力信息和/或交换支持动态连接切换的能力信息。根据实施例,多连接操作可以指示增强型多连接多无线通信(EMLMR)或增强型多连接单无线通信(EMLSR)。根据实施例,可以仅交换多连接操作的能力信息,该能力信息可以指示EMLMR或EMLSR,还可以隐含地标识其支持动态连接切换。
图4是示出根据本公开的示例实施例的通信设备400的框图。通信设备400可以包括处理模块410和通信模块420。
图4所示的通信设备400可以应用于发送方。在此情况下,处理模块 410可以被配置为:确定第一消息帧,其中,第一消息帧可以包括指示动态连接切换的信息;通信模块420可以被配置为:发送第一消息帧。此外,通信模块420可以向接收方发送支持多连接操作的能力信息和/或支持动态连接切换的能力信息,或者从接收方接收这样的能力信息。也就是说,在图4所示的通信设备400可以应用于发送方时,处理模块410和通信模块420可以执行参照图2描述的操作,为了简明,在此可以省略重复的描述。
图4所示的通信设备400可以应用于接收方。在此情况下,通信模块420可以被配置为:接收第一消息帧,其中,第一消息帧可以包括指示动态连接切换的信息;处理模块410可以被配置为:基于第一消息帧,执行连接的切换操作。此外,通信模块420可以向发送方发送支持多连接操作的能力信息和/或支持动态连接切换的能力信息,或者从发送方接收这样的能力信息。也就是说,在图4所示的通信设备400可以应用于接收方时,处理模块410和通信模块420可以执行参照图3描述的操作,为了简明,在此可以省略重复的描述。
将理解,图4的通信设备所涉及的第一消息帧、信息等内容可以类似于参照图2和/或表1所描述的实施例,为了简明,在此省略重复的描述。此外,图4所示的通信设备400仅是示例性的,本公开的实施例不限于此,例如,通信设备400还可以包括其他模块,例如,存储器模块等。此外,通信设备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,以支持各种功能。
