具体实施方式
提供以下参照附图的描述,以帮助全面理解由所附权利要求及其等同物限定的本公开的各种实施例。本公开的各种实施例包括各种具体细节,但是这些具体细节仅被认为是示例性的。此外,为了清楚和简洁,可以省略对公知的技术、功能和构造的描述。
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点。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,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。
在目前的无线通信中,要求AP MLD可以在任意时刻能够增加或删除其附属AP,根据本公开的实施例提供了用于实现AP MLD删除或增加附属AP(连接)的通信方法和通信装置。
图2是示出根据本公开实施例的多连接下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接入点,如图2所示的AP MLD。
参照图2,在步骤210中,确定第一消息帧,其中,第一消息帧包括与增加和/或删除至少一个连接有关的信息。根据本公开的实施例,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)帧等,然而,本公开不限于此,第一消息帧可以是例如新定义的动作帧。
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:接入点设备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,接入点设备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。
在本公开的实施例中,在与增加和/或删除至少一个连接有关的信息中,增加和/或删除至少一个连接可以指AP MLD增加和/或删除至少一个附属AP,例如,在图1中的AP1、AP2和AP3的基础上增加至少一个新的AP(其可以对应于新的连接),或者可以删除AP1、AP2和AP3中的至少一个。
在步骤220中,发送第一消息帧。例如,可以在AP MLD所支持的多个连接中的任意连接下发送第一消息帧,以通过携带在第一消息帧中的信息通知接收方(non-AP STA MLD)更改(增加和/或删除)了哪些连接,从而双方可以利用更改后的连接进行通信。
根据本公开的实施例,与增加和/或删除至少一个连接有关的信息可以以信息元素的形式携带在第一消息帧中,并通过广播的形式进行帧的发送。例如,携带在第一消息帧中的与增加和/或删除至少一个连接有关的信息可以具有多连接信息元素的形式。然而,本公开不限于此,可以以其他方式或其他类型的信息元素来携带该信息。在下文中,为了描述的方便,以多连接信息元素的形式作为示例,来描述与增加和/或删除至少一个连接有关的信息。下面将参照表1至表4对该信息进行详细描述。
仅作为示例性的,多连接信息元素可以具有如下面表1所示的格式。
表1.多连接信息元素的格式
Figure PCTCN2021107200-appb-000001
在表1中,元素标识(Element ID)可以被设置为特定值,以标识多连接信息元素;长度(Length)可以表示连接信息元素的长度信息;元素标识扩展(Element ID Extension)可选地存在,用于标识连接信息元素的扩展;多连接控制域(Multi-Link Control)、公共信息域(Common info)和连接信息域(Link Info)可以包括与增加和/或删除至少一个连接有关的信息。此外,表1所示的多连接信息元素仅是示例性的,本公开不限于此。
根据本公开的示例实施例,多连接控制域(Multi-Link Control)可以具有如下面表2所示的格式。
表2.多连接控制域的格式
Figure PCTCN2021107200-appb-000002
根据本公开的示例实施例,多连接信息元素可以包括用于标识重配置多连接信息元素的类型标识,例如,表2中的类型(Type)子域。类型标识(Type)可以用于区分多连接信息元素的各种变体,虽然在表2中示出了类型标识(Type)可以具有3比特位,但这仅是示例性的,而不是对本公开的限制,类型标识(Type)的比特位数可以根据通信环境或通信标准而改变。作为示例,当类型标识(Type)被设置为例如但不限于“0”时,可以标识基本(Basic)多连接信息元素;当类型标识(Type)被设置为例如但不限于“1”时,可以标识探测请求(Probe Request)多连接信息元素;当类型标识(Type)被设置为特定值(例如,在类型标识(Type)具有3比特位的情况下,类型标识(Type)被设置为“2-7”中的任意值)时,可以标识重配置多连接信息元素。
表2中的位图存在(Bitmap present)子域可以用于表示是否存在增加和/或删除的连接。然而,本公开不限于此,例如,位图存在(Bitmap present)子域还可以用于表示表1的公共信息中的各种子域是否存在。
此外,多连接控制域还可以包括一个(或更多个)保留(Reserved)位。
根据本公开的示例实施例,位图存在(Bitmap present)子域可以具有如下面表3所示的格式。
表3.Bitmap present的格式
Figure PCTCN2021107200-appb-000003
根据本公开的实施例,与增加和/或删除至少一个连接有关的信息可以包括MLD MAC地址存在标识,例如,表3中的MLD MAC地址存在(MLD MAC address present)子域。MLD MAC地址标识(MLD MAC address present)子域)可以用于指示MLD MAC地址在该信息(多连接信息元素)中的存在性。MLD MAC地址可以标识AP MLD的多连接设备MAC地址。根据实施例,一个多连接设备(例如,AP MLD)可以具有唯一的多连接设备MAC地址标识,以用于识别该多连接设备。MLD MAC地址存在标识(MLD MAC address present)可以根据是否存在增加和/或删除至少一个连接而被对应地设置。例如,可以基于将要在下文描述的增加连接存在(Add link present)子域、删除连接存在(Delete link present)子域,来设置MLD MAC地址存在标识(MLD MAC address present)。
例如,在存在增加的连接的情况下(例如,增加连接存在(Add link present)子域指示存在新增加的连接),MLD MAC地址存在标识(MLD MAC address present)可以被设置为第一值(例如但不限于“1”),以指示MLD MAC地址存在于与增加和/或删除至少一个连接有关的信息(多连接信息元素)中。在此情况下,由于新增加的连接将会用于在接入点与站点之间进行通信,因此,在多连接信息元素中需要携带MLD MAC地址,例如,该MLD MAC地址可以用于在新增加的连接下协商会话密钥。
例如,在仅存在删除的连接的情况下(例如,删除连接存在(Delete link present)子域指示存在将要被删除的连接,并且增加连接存在(Add link present)子域指示不存在新增加的连接),MLD MAC地址存在标识(MLD MAC address present)可以被设置为第二值(例如但不限于“0”),以指示MLD MAC地址不存在于与增加和/或删除至少一个连接有关的信息(多连接信息元素)中。在此情况下,由于删除的连接不再用于接入点与站点之间的通信,因此,在多连接信息元素中可以不携带MLD MAC地址,从而可以精简多连接信息元素中携带的内容,降低功耗。
根据本公开的实施例,与增加和/或删除至少一个连接有关的信息可以 包括第一标识和/或第二标识,例如,第一标识可以是表3中的增加连接存在(Add link present)子域,第二标识可以是表3中的删除连接存在(Delete link present)子域。具体地,第一标识(Add link present)可以用于标识新连接的增加,第二标识(Delete link present)可以用于标识已有连接的删除。
根据本公开的实施例,与增加和/或删除至少一个连接有关的信息可以包括第三标识和/或第四标识,例如,第三标识可以是表3中的连接数1(Link count 1)子域,第四标识可以是表3中的连接数2(Link count 2)。具体地,第三标识(Link count 1)可以用于标识增加的连接数量,第四标识(Link count 2)可以用于标识删除的连接数量。
根据本公开的实施例,可以利用表1的连接信息(Link Info)域来标识增加和/或删除的连接的信息。例如,连接信息(Link Info)域可以包括与增加和/或删除的连接相对应的连接标识(Link ID)。作为示例,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(basis service set identifier)的组合信息。例如,连接信息(Link Info)域可以包括与增加和/或删除的连接相对应的AP的MAC地址。此外,连接信息(Link Info)域还可以包括一个比特位,其用于标识当前的连接信息域所表示的连接是增加的连接还是删除的连接。
例如,第一标识(Add link present)可以利用一个比特位来标识,作为示例,如果其被设置为特定值(例如但不限于,“1”),则可以标识增加了新的连接,并且第三标识(Link count 1)可以标识增加连接的数量,增加的连接信息可以在连接信息(Link Info)域中进行标识。
例如,第二标识(Delete link present)可以利用一个比特位来标识,作为示例,如果其被设置为特定值(例如但不限于,“1”),则可以标识删除了已有的连接,并且第四标识(Link count 2)可以标识删除连接的数量,删除的连接的信息可以在连接信息(Link Info)域中进行标识。
在表3中,Link count子域(Link count 1和Link count 2)为可选存在。例如,可以省略Link count子域,在连接信息(Link Info)域中利用一个比特位来标识相应的连接为增加的连接或删除的连接。当存在Link count子域(Link count 1和Link count 2)时,Link count子域和连接信息(Link Info)域中的该一个比特位可以结合使用,以保证解码准确性,即,确保与增加和 /或删除至少一个连接有关的信息的准确性。在另一实施例中,如果连接信息(Link Info)域包括用于标识相应的连接为增加的连接或删除的连接的比特位,则可以第一标识(Add link present)和第二标识(Delete link present)也可以是可选存在的。
例如,如果存在删除的连接(不存在新增加的连接),则MLD MAC地址存在标识(MLD MAC address present)可以被设置为例如但不限于“0”,以标识MLD MAC地址不会出现在例如表1的公共信息(Common Info)域中,而在连接信息(Link Info)域中包括删除连接的Link ID/AP的MAC地址。
例如,如果存在增加的连接(不管是否存在删除的连接),则MLD MAC地址存在标识(MLD MAC address present)可以被设置为例如但不限于“1”,以标识MLD MAC地址会出现在公共信息(Common Info)域中,而在连接信息(Link Info)域中包括增加连接的Link ID/AP的MAC地址。根据本公开的实施例,当存在增加的连接的情况下,连接信息(Link Info)域可以包括在增加的连接下进行信息传输的信息。例如,连接信息(Link Info)域可以包括信标帧间隔等信息。
虽然在表3中示出了第一标识(Add link present)和第二标识(Delete link present)位于不同的子域,但是在另一实施例中,第一标识和第三标识可以被包括在同一域中,如下面的表4中的“Add link/Delete link present”所示。
表4.Bitmap present的格式
Figure PCTCN2021107200-appb-000004
参照表4,增加连接/删除连接存在(Add link/Delete link present)子域可以利用,例如但不限于,两个比特位来标识。作为非限制性实施例,当该子域被设置为“00”时,可以标识存在增加的连接(增加);当该子域被设置为“01”时,可以标识存在删除的连接(删除);当该子域被设置为“11”时,可以标识既存在增加的连接也存在删除的连接(增加&删除);并且类似于表3中描述的实施例,可以设置对应的连接数量(例如,Link cout 1、Link cout 2)。表4中的MLD MAC地址存在(MLD MAC address present)子域也可以类似于表3中描述的实施例,为了避免冗余,在此省略重复的描述。
虽然表3和表4中,Link cout 1和Link cout 2被示出在不同的子域中,但是二者也可以被包括在同一子域中。例如,在该子域中,可以利用较高比特位来标识增加的连接数量,利用较低比特位来标识删除的连接数量。
将理解,表1至表4所示的实施例仅是说明性的,而不是限制性的,可以在表1至表4中增加其他的内容或删除其中的部分内容,或者改变表1至表4中所包含内容的位置。此外,参照表1至表4描述的各个域或者子域的比特位数也仅是说明性的,而不是限制性的,可以根据实际应用来不同地改变相应的比特位数。
根据本公开的实施例,通过在第一消息帧(信标帧、探测响应帧、关联响应帧、重关联响应帧或其他新定义的动作帧)中封装携带有删除和/或增加附属AP(连接)的重配置多连接信息元素,并进行帧的发送,使得AP MLD能够在任意时刻删除和/或增加附属AP,提高频谱利用率、系统的灵活性。
图3是示出根据本公开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支持多连接通信的站点(non-AP STA 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与增加和/或删除至少一个连接有关的信息。
根据本公开的实施例,所述信息可以包括第一标识和/或第二标识,例如,表3中的Add link present子域、Delete link present子域或者表4中的Add link/Delete link present子域。其中,第一标识可以用于标识新连接的增加,第二标识可以用于标识已有连接的删除。
根据本公开的实施例,所述信息还可以包括第三标识和/或第四标识,例如,表3和表4中的Link count 1和Link count 2。其中,第三标识可以用于标识增加的连接数量,第四标识可以用于标识删除的连接数量。
根据本公开的实施例,第一标识和述第三标识可以被包括在同一域中,例如,表4中的Add link/Delete link present子域。
根据本公开的实施例,所述信息可以包括连接信息域,例如,表1中的Link Info域。该连接信息域可以用于标识增加和/或删除的连接的信息。
根据本公开的实施例,在存在增加的连接的情况下,连接信息域可以包括关于在增加的连接下进行信息传输的信息。
根据本公开的实施例,所述信息可以包括多连接设备MLD MAC地址存在标识,例如,表3和表4中的MLD MAC address present子域。其中,MLD MAC地址存在标识可以用于指示MLD MAC地址在所述信息中的存在性。
根据本公开的实施例,在存在增加的连接的情况下,MLD MAC地址存在标识可以被设置为第一值,以指示MLD MAC地址存在于所述信息中;在仅存在删除的连接的情况下,MLD MAC地址存在标识可以被设置为第二值,以指示MLD MAC地址不存在于所述信息中。
根据本公开的实施例,与增加和/或删除至少一个连接有关的信息可以具有多连接信息元素的形式,如表1所示。其中,多连接信息元素可以包括用于标识重配置多连接信息元素的类型标识。
上述参照表1至表4所描述的关于第一消息帧及其携带的信息的实施例可以应用于图3的通信方法中,为了避免冗余,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通信操作。例如,non-AP STA MLD可以基于第一消息帧中携带的信息来相应地增加连接,并且利用增加的连接与AP MLD进行通信(例如,传输数据、信号、密钥等)。例如,non-AP STA MLD可以基于第一消息帧中携带的信息来相应地删除连接,并且在随后的通信操作中不再利用已删除的连接。
图4是示出根据本公开的实施例的通信装置400的框图。
参照图4,通信装置400可以包括处理模块410和收发模块420。图4所示的通信装置可以应用于AP MLD或者non-AP STA MLD。
