Description

通信方法和通信设备 技术领域
本公开涉及通信领域,更具体地说,涉及多连接下的通信方法和通信设备。
背景技术
目前的Wi-Fi技术所研究的范围为:320MHz的带宽传输、多个频段的聚合及协同等,期望能够相对于现有的标准提高至少四倍的速率以及吞吐量,其主要的应用场景为视频传输、AR(Augmented Reality,增强现实)、VR(Virtual Reality,虚拟现实)等。
多个频段的聚合及协同是指设备间同时在2.4GHz、5GHz及6GHz的频段下进行通信,对于设备间同时在多个频段下通信需要定义新的MAC(Media Access Control,介质访问控制)机制来进行管理。此外,还期望多频段的聚合及协同能够支持低时延传输。
目前多频段的聚合及系统技术中将支持的最大带宽为320MHz(160MHz+160MHz),此外还可能会支持240MHz(160MHz+80MHz)及其它带宽。
在目前的技术中,站点(STA:Station)和接入点(AP:Access Point)可以是多连接设备(MLD:multi-link device),即,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。因此,在目前的技术中,STA与AP之间可以存在多个连接,并且正在对这两种设备在多连接下的通信进行研究。当站点接入网络后,会接收到每个连接下分配的IP地址,但是由于站点只在一个连接下与AP建立了初始关联,因此还需要在多个连接下给站点分配IP地址,这样分配IP地址占用的无线资源时间较长,不利于频谱的高效利用。

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。
一种相关技术中,为了使得站点能够快速的接入到网络,可以采用了 FILS(快速初始连接建立:fast initial link setup)机制,FILS机制包含IP地址的预配置机制。这种FILS机制中的IP地址预分配机制只能满足单连接下的需求。
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,或者2.4GHz、5GHz或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。在下文中,为了便于描述,non-AP STA、站点、站点设备可以互换地使用。
根据本公开的示例实施例,可以提供能够在多个连接下为站点分配IP地址的FILS机制。
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设备。
参照图2,在步骤210中,可以确定第一消息帧。其中,第一消息帧包括用于指示站点设备请求快速初始连接建立(FILS)IP地址配置的信息。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:支持多连接通信的站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,站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。
根据本公开的示例实施例,用于指示站点设备请求快速初始连接建立(FILS)IP地址配置的信息可以包括FILS IP地址分配信息元素,其用于标 识站点设备请求的IP地址的类型信息。作为示例,FILS IP地址分配信息元素可以被定义为如下面的表1至表3所示。
表1.FILS IP地址分配信息元素(FILS IP Address Assignment element)
Figure PCTCN2021070950-appb-000001
在表1中,请求的IP地址数据(IP Address Data)域可以被定义为如下面的表2所示。
表2.请求的IP地址数据(IP Address Data field for request)
Figure PCTCN2021070950-appb-000002
在表2中,IP地址请求控制(IP Address Request Control)子域可以被定义为如下面的表3所示。
表3.IP地址请求控制子域(IP Address Request Control subfield)
Figure PCTCN2021070950-appb-000003
在表3中,IPv4子域可以被设置为不同的值,以指示站点对IPv4地址的请求,例如,IPv4子域可以被设置为0,以指示站点不请求IPv4地址;IPv4子域可以被设置为1(保留);IPv4子域可以被设置为2,以指示站点请求新IPv4地址;IPv4子域可以被设置为3,以指示请求以元素形式存在的IPv4地址。根据本公开的实施例,当IPv4子域被设置为请求特定的IPv4地址时,表2中的Requested IPv4 Address(4字节)可以携带non-AP STA正在请求的特定IPv4地址类型。
在表3中,IPv6子域可以被设置为不同的值,以指示站点对IPv6地址的请求,例如,IPv6子域可以被设置为0,以指示站点不请求IPv6地址;IPv6子域可以被设置为1(保留);IPv6子域可以被设置为2,以指示站点请求新IPv6地址;IPv6子域可以被设置为3,以指示请求以元素形式存在的IPv6地址。根据本公开的实施例,当IPv6子域被设置为请求特定的IPv6地址时,表2中的Requested IPv6 Address(16字节)可以携带non-AP STA正在请求的特定IPv6 地址类型。
在表3中,如果站点请求一个或多个DNS服务器地址,则DNS Server Address Request(DNS服务器地址请求)子域可以被设置为1。请求的DNS服务器的类型可以对应于请求的IP地址的类型。例如,如果请求IPv4和IPv6二者,则可以将DNS Server Address Request设置为1,来请求针对这两种类型的DNS服务器地址。
将理解的是,以上关于表3所描述的各个子域的设置值仅是示例性的,而不是对本公开的示例实施例的限制,可以标识站点设备请求的IP地址的类型的其他值也包括在本公开的范围内。
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1至表3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。
根据本公开的实施例,用于指示站点设备请求快速初始连接建立(FILS)IP地址配置的信息(例如,FILS IP地址分配信息元素)可以是MLD级信息元素,用于指示接入点设备为站点设备的多个连接分配一个IP地址。也就是说,在FILS IP地址分配信息元素为MLD级信息元素的情况下,站点设备的多个连接可以共用一个IP地址。在一个实施例中,在MLD级信息元素的情况下,单个FILS IP地址分配信息元素)可以被封装在第一消息帧中,例如,FILS IP地址分配信息元素以独立的信息元素形式被封装在关联请求(association request)帧或重关联请求(re-association request)帧中。在另一个实施例中,在MLD级信息元素的情况下,FILS IP地址分配信息元素可以被封装在多连接探测请求(ML probe request)帧中。多连接探测请求帧可以包括如下面的表4所示的ML信息元素(ML element)。
表4.多连接信息元素(Multi-Link(ML)Element)
Figure PCTCN2021070950-appb-000004
参照表4,在MLD级信息元素的情况下,FILS IP地址分配信息元素可以被封装在多连接探测请求帧的公共信息(Common Info)子域的中。也就是说,FILS IP地址分配信息元素不是以单独的信息元素的形式存在于第一消息帧(例如,多连接探测请求帧)中,而是被嵌入在另一信息元素(ML信息元素)中。
根据本公开的实施例,用于指示站点设备请求快速初始连接建立(FILS)IP地址配置的信息可以为连接级信息元素,用于指示接入点设备为站点设备的多个连接分别分配对应的IP地址。也就是说,站点设备的多个连接中的每个连接均可以具有其IP地址。多个连接中的各个连接所对应的IP地址的类型可以相同或者不同。在此情况下,用于指示站点设备请求快速初始连接建立(FILS)IP地址配置的信息还可以包括与站点设备的多个连接中的每个连接相对应的连接标识,并且FILS IP地址分配信息元素与每个连接的连接标识相对应。也就是说,可以利用“FILS IP地址分配信息元素+连接标识”来标识每个连接的IP地址请求。
在本公开的一个实施例中,在连接级信息元素的情况下,“FILS IP地址分配信息元素+连接标识”可以封装在表4所示的“连接信息(Link Info)”子域中。
此外,可以理解的是表4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4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2,在步骤22中,可以发送第一消息帧。例如,站点设备可以在多个连接中的任意连接下向接入点设备发送携带参照表1至表4描述的信息的第一消息帧,以向接入点设备请求IP地址。
可以理解的是,图2所示的通信方法所包括的步骤仅是示例性的,本公开的实施例不限于此。例如,图2所示的通信方法还可以包括:发送第二消息帧,其中,第二消息帧包括站点设备支持FILS IP地址配置的信息。例如,第二消息帧可以携带指示站点设备支持FILS IP地址配置的标识位。 也就是说,第二消息帧可以携带设备支持FILS功能的标识位。根据实施例,第二消息帧可以为探测请求帧或多连接探测请求帧。作为示例,第二消息帧可以是在第一消息帧之前发送的。
图2所示的通信方法可以在多个连接下为站点分配IP地址,提高频谱的利用率。
图3是示出根据示例实施例的站点设备向接入点设备请求FILS IP地址配置的示图。
参照图3,在操作310中,站点设备可以向接入点设备发送第二消息帧,并且在第二消息帧中携带站点设备支持FILS IP地址配置的信息,例如,第二消息帧可以是探测请求帧或多连接探测请求帧。
在操作320中,站点设备可以从接入点设备接收反馈帧,例如,探测响应帧或多连接探测响应帧。可选地,在反馈帧(例如,探测响应帧或多连接探测响应帧)中可以携带接入点设备支持FILS IP地址配置的信息。
在操作330中,站点设备可以向接入点设备发送第一消息帧,并且在第一消息帧中携带用于指示站点设备请求快速初始连接建立FILS IP地址配置的信息。例如,第一消息帧可以是关联请求帧或重关联请求帧。操作330可以类似于图2的通信方法。
在操作340中,站点设备可以从接入点设备接收反馈帧,例如,关联响应帧或重关联响应帧,从而站点设备可以与接入点设备建立关联连接。
随后,站点设备可以与接入点设备执行其他通信操作,例如,基于密钥的认证操作。
在操作350中,站点设备可以从接入点设备接收分配的IP地址。
将理解,图3所示的站点设备与接入点设备的交互通信仅是示例性的,而不是对本公开的实施例的限制。在实施例中,可以省略或合并图3所示的部分操作,例如,可以省略操作310和操作320,或者接入点设备支持FILS功能的标识位可以不被携带在操作320中的反馈帧(例如,探测响应帧或多连接探测响应帧)中,而是携带在操作340的反馈帧(例如,关联响应帧或重关联响应帧)中。在实施例中,图3所示的交互通信还可以包括认证操作,或者接入点设备与上层的交互操作。
图3所示的通信方法可以在站点设备与接入点设备建立关联连接的过程中交互关于FILS的信息,随后(例如,在认证操作之后)可以进行FILS IP地址的分配,这样可以节省信令,提高无线通信效率。
图4是示出根据本公开的实施例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支持多连接通信的接入点设备。
参照图4,在步骤410中,接入点设备可以从站点设备接收第一消息帧,其中,第一消息帧可以包括用于指示支持多连接通信的站点设备请求快速初始连接建立FILS IP地址配置的信息。
根据实施例,该信息可以包括FILS IP地址分配信息元素,用于标识站点设备请求的IP地址的类型信息。FILS IP地址分配信息元素可以类似于上述参照表1至表3的描述,为了简明,在此省略重复的描述。
根据实施例,该信息为MLD级信息元素,用于指示接入点设备为站点设备的多个连接分配一个IP地址。
根据实施例,该信息为连接级信息元素,用于指示接入点设备为所述站点设备的多个连接分别分配对应的IP地址。在此情况下,该信息还可以包括:与站点设备的多个连接中的每个连接相对应的连接标识,其中,FILS IP地址分配信息元素与每个连接的连接标识相对应。
根据实施例,第一消息帧可以为关联请求帧、重关联请求帧或多连接探测请求帧。
根据实施例,在该信息为MLD级信息元素情况下,FILS IP地址分配信息元素可以包括在所述关联请求帧或所述重关联请求帧中。
根据实施例,多连接探测请求帧包括如表4所示的多连接信息元素,其中,用于指示支持多连接通信的站点设备请求快速初始连接建立FILS IP地址配置的信息可以包括在多连接信息元素中。
根据实施例,在该信息为MLD级信息元素情况下,FILS IP地址分配信息元素包括在多连接信息元素的公共信息子域中。
根据实施例,在该信息为连接级信息元素情况下,FILS IP地址分配信息元素以及对应的连接标识可以包括在多连接信息元素的连接信息子域中。
在步骤420中,接入点设备可以基于第一消息帧为站点设备分配IP地址。例如,如果第一消息帧中的信息指示MLD级信息元素,接入点设备可以为站点设备的多个连接分配共享的一个IP地址;如果第一消息帧中的信息指示连接级信息元素,接入点设备可以为站点设备的多个连接分别分配对应的IP地址。为多个连接分配的各IP地址可以具有相同或不同的类型。
根据本公开的实施例,步骤420可以包括:响应于站点设备具有增强型多连接多无线通信(EMLMR:enhanced multi-link multi-radio)功能,接入点设备为站点设备的多个连接分别分配对应的IP地址。在该实施例中,接入点设备可以从站点设备发送的能力信息中获取站点设备是否具有EMLMR功能。
根据本公开的实施例,步骤420可以包括:响应于所述站点设备具有增强型多连接单无线通信(EMLSR:enhanced multi-link single-radio)功能,所述接入点设备为站点设备的多个连接分配一个IP地址。在该实施例中,接入点设备可以从站点设备发送的能力信息中获取站点设备是否具有EMLSR功能。
可以理解的是,图4所示的通信方法所包括的步骤仅是示例性的,本公开的实施例不限于此。例如,图4所示的通信方法还可以包括:发送第三消息帧,其中,第三消息帧可以包括指示接入点设备支持请求的FILS IP地址配置的信息。也就是说,第三消息帧可以包括接入点设备支持FILS功能的标识位。根据实施例,第三消息帧可以为关联响应帧、重关联响应帧或多连接探测响应帧。作为示例,可以在步骤420执行之前发送第三消息帧。
图4所示的通信方法可以在多个连接下为站点分配IP地址,提高频谱的利用率。
图5是示出根据示例实施例的接入点设备与站点设备交互通信的示图。
参照图5,在操作510中,接入点设备可以广播信标(beacon)帧,站点设备可以接收广播的信标帧。
在操作520中,接入点设备可以从站点设备接收第一消息帧(例如, 关联请求帧或重关联请求帧),其中,第一消息帧可以用于指示支持多连接通信的站点设备请求快速初始连接建立FILS IP地址配置的信息。该操作520可以类似于图4所示的步骤410,为了简明,在此省略重复的描述。
在操作530中,接入点设备可以向站点设备发送第三消息帧,其中,第三消息帧可以包括指示接入点设备支持请求的FILS IP地址配置的信息。也就是说,第三消息帧可以携带指示接入点设备支持FILS功能的标识位。
随后,接入点设备可以与站点设备执行其他通信操作(例如,基于密钥的认证操作),或者接入点设备可以执行与上层的通信操作。
在操作540中,接入点设备可以向站点设备发送分配的IP地址。该操作540可以类似于图4的步骤420,为了简明,在此省略重复的描述。
将理解,图5所示的接入点设备与站点设备交互通信的操作仅是示例性的,而不是对本公开的实施例的限制。在实施例中,可以省略或合并图5所示的部分操作,或者还可以包括更多其他的操作。
图5所示的通信方法可以在站点设备与接入点设备建立关联连接的过程中交互关于FILS的信息,随后(例如,在认证操作之后)可以进行FILS IP地址的分配,这样可以节省信令,提高无线通信效率。
在本公开的实施例中,站点可以在ML探测请求帧、关联请求帧或重关联请求帧中携带FILS IP地址分配信息元素。例如,可以将FILS IP地址分配信息元素封装在关联请求帧或重关联请求帧中,标识FILS IP地址分配元素为MLD级,即,AP可以在每个连接下分配相同类型的IP地址。再例如,FILS IP地址分配信息元素封装在ML信息元素中,以MLD级或连接级(link级)的信息元素出现。如参照表4的描述,当以MLD级的形式出现时,FILS IP地址分配信息元素可以封装在公共信息子域中;当以连接级信息元素的形式出现时,AP可以为每个连接分配不同的IP地址,并且“连接标识(link ID)+FILS IP地址分配信息元素”可以封装在连接信息子域中。
在本公开的实施例中,可以考虑站点的EMLMR及EMLSR功能。AP可以根据站点的能力信息值,如果站点为EMLMR站点,AP可以为其在每个连接下分配IP地址;如果站点为EMLSR站点,由于EMLSR站点在某一时刻只能进行单连接的通信,所以AP可以只为其分配一个IP地址,这样分配 IP地址可在每个连接下复用。
图6是示出根据实施例的通信设备的框图。通信设备600可以包括处理模块610和通信模块620。
在一个实施例中,通信设备600可以应用于支持多连接通信的站点设备。在此情况下,处理模块610可以被配置为:确定第一消息帧,其中,第一消息帧可以包括用于指示站点设备请求快速初始连接建立FILS IP地址配置的信息;通信模块620可以被配置为:发送第一消息帧。

在通信设备600应用于支持多连接通信的接入点设备的情况下,通信设备600可以执行参照图4描述的通信方法以及图3和图5中由接入点设备执行的操作,为了简明,在此省略重复的描述。
根据本公开的示例实施例的通信设备600可以在多个连接下为站点分配IP地址,提高频谱的利用率,并且可以节省信令,提高无线通信效率。
此外,图6所示的通信设备600仅是示例性的,本公开的实施例不限于此,例如,通信设备600还可以包括其他模块,例如,存储器模块等。此外,通信设备600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。
