具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：无线局域网(wireless local area network，WLAN)系统，可选地，本申请实施例还可以应用于其他系统中，例如，长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。
以下仅以WLAN系统为例，描述本申请实施例的应用场景以及本申请实施例的方法。
具体而言，本申请实施例可以应用于无线局域网(Wireless Local Area Network， WLAN)，并且本申请实施例可以适用于WLAN当前采用的国际电工电子工程学会(institute of electrical and electronics engineers，IEEE)802.11系列协议中的任意一种协议。WLAN可以包括一个或多个基本服务集(basic service set，BSS)，基本服务集中的网络节点包括接入点(access point，AP)和站点(station，STA)。IEEE 802.11ad在原有的BSS基础上，引入个人基本服务集(personal basic service set，PBSS)和个人基本服务集控制节点(PBSS control point，PCP)。每个个人基本服务集可以包含一个AP/PCP和多个关联于该AP/PCP的站点。应理解，本申请实施例中与站点通信的设备可以是AP也可以是PCP，为了简便下文中仅以AP与站点通信为例进行描述，PCP与站点通信的行为与此类似。
应理解，本申请实施例中，第一设备和/或第二设备可以是WLAN中STA，该STA也可以称为系统、用户单元、接入终端、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理、用户装置或用户设备(user equipment，UE)。STA可以为无线通讯芯片、无线传感器或无线通信终端。例如，STA可以为支持WiFi通讯功能的移动电话、支持WiFi通讯功能的平板电脑、支持WiFi通讯功能的机顶盒、支持WiFi通讯功能的智能电视、支持WiFi通讯功能的智能可穿戴设备、支持WiFi通讯功能的车载通信设备和支持WiFi通讯功能的计算机。可选地，STA可以支持802.11ax、802.11ac、802.11ad、802.11ay、802.11n、802.11g、802.11b及802.11a等多种WLAN制式。
另外，本申请实施例中，第一设备和/或第二设备也可以是WLAN中AP，该AP可以用于与接入终端通过无线局域网进行通信，并将接入终端的数据传输至网络侧，或将来自网络侧的数据传输至接入终端。AP也称之为无线访问接入点或热点等。AP可以是移动用户进入有线网络的接入点，主要部署于家庭、大楼内部以及园区内部，典型覆盖半径为几十米至上百米，当然，也可以部署于户外。AP相当于一个连接有线网和无线网的桥梁，其主要作用是将各个无线网络客户端连接到一起，然后将无线网络接入以太网。具体地，AP可以是带有无线保真(Wireless Fidelity，WiFi)芯片的终端设备或者网络设备。可选地，AP可以为支持802.11ax制式的设备，进一步可选地，该AP可以支持802.11ax、802.11ac、802.11ad、802.11ay、802.11n、802.11g、802.11b及802.11a等多种WLAN制式。
在本申请实施例中，第一设备或第二设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是AP或STA，或者，是AP或STA中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于：磁存储器件(例如，硬盘、软 盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1示出了根据本申请实施例的应用场景的示意图。如图1所示的场景系统可以是WLAN系统，图1的WLAN系统可以是由多个基本服务集(basic service set，BSS)构成的WLAN场景，该WLAN系统可以包括一个或多个AP，以及一个或多个STA，图1以两个AP(AP 1和AP 2)和四个STA(STA 1和STA 2)为例，其中，AP与AP、AP与STA、STA与STA之间可以通过各种标准进行无线通信。
应理解，本文所涉及的通信可以是直接通信，也可以是间接通信，本申请实施例对此不作限定。例如，假设STA 3不属于AP 1的基本服务集合，AP 1可以先将信息发送给AP 2，再由AP 2将该信息发送给STA 3，从而实现AP 1和STA 3之间的间接通信。同理，STA 1与STA 4也可以通过AP 1或AP 2进行间接通信，此处不再赘述。
上述提到的基本服务集合是802.11局域网的基本组成部分，一个BSS包括一个接入点(access point，AP)和若干个站点(station，STA)，所有的STA在本BSS内都可以直接通信，但在和本BSS之外的STA进行通信时，都需要通过本BSS的AP。
图2是本申请实施例的多频段通信的方法200的示例性流程图。应理解，图2所示的方法中的第一设备可以对应于图1所示的系统100中的AP或STA，第二设备也可以对应于图1所示的AP或STA。
S210，第一设备接收第二设备发送的第一帧，所述第一帧携带用于请求在至少两个频段上进行认证、连接或重新连接的请求信息。
其中，所述至少两个频段可以是多个频段中的至少两个频段，例如，所述至少两个频段可以包括2.4GHz、5GHz、60GHz和6GHz中的一个或多个频段，或者，所述至少两个频段也可以包括两个或多个相同频段，例如，所述至少两个频段可以包括两个或多个2.4GHz，或者所述至少两个频段也可以包括两个或多个5GHz、两个或多个60GHz、两个或多个6GHz，这里不再赘述。此外，所述至少两个频段也可以包括其他的频段，本申请实施例对此不作限定。
可选地，所述第一帧可以为认证帧(authentication frame)、连接请求帧(association request frame)或重新连接请求帧(reassociation request frame)。
例如，当所述第一帧携带用于请求在至少两个频段上进行认证的请求信息时，所述第一帧可以为认证帧；当所述第一帧携带用于请求在至少两个频段上进行连接的请求信息时，所述第一帧可以为连接请求帧；当所述第一帧携带用于请求在至少两个频段上进行重新连接的请求信息时，所述第一帧可以为重新连接请求帧。
在一种可能的实现方式中，所述第二设备可以通过所述请求信息向所述第一设备请求同时在所述至少两个频段上进行认证、连接或重新连接。
应理解，上述同时在所述至少两个频段上进行认证、连接或重新连接可以是指：所述第二设备可以通过所述请求信息，请求所述第一设备在接收到所述第一帧后，可以根据所述请求信息的请求在至少两频段上进行认证、连接或重新连接。即根据所述请求信息，通 过一次交互，就可以实现在至少两个频段上进行认证、连接或重新连接。
例如，以所述请求信息请求在至少两个频段上进行认证为例，所述第二设备向所述第一设备发送所述第一帧，所述第一帧可以携带用于请求在至少两个频段上进行认证的请求信息，相应地，所述第一设备接收到所述第一帧后，可以根据所述请求信息的请求在至少两频段上进行认证，即通过所述第一帧，就可以实现在至少两个频段上进行认证。所述请求信息请求在至少两个频段上进行连接或重新连接的过程与此类似，这里不再赘述。
在一种可能的实现方式中，所述请求信息可以包括至少两个请求位，所述至少两个请求位可以与所述至少两个频段一一对应，每个所述请求位可以用于请求在对应频段上进行认证、连接或重新连接。
例如，所述至少两个频段可以包括2.4GHz、5GHz和60GHz，此时，所述请求信息可以包括三个请求位，所述三个请求位可以与2.4GHz、5GHz和60GHz一一对应。其中，所述三个请求位中的一个可以与2.4GHz对应，用于请求在2.4GHz上进行认证、连接或重新连接；所述三个请求位中的另一个可以与5GHz对应，用于请求在5GHz上进行认证、连接或重新连接；所述三个请求位中的再一个可以与60GHz对应，用于请求在60GHz上进行认证、连接或重新连接。
可选地，所述请求位可以包括至少一个比特位。
例如，所述请求位可以与2.4GHz对应，所述请求位可以包括一个比特位，此时，若所述请求位为1，则所述请求位用于请求在2.4GHz上进行认证、连接或重新连接；若所述请求位为0，则所述请求位未请求在2.4GHz上进行认证、连接或重新连接。
应理解，所述请求信息可以仅用于请求所述至少两个频段中的部分频段。
例如，所述至少两个频段可以包括2.4GHz、5GHz和60GHz，所述请求信息可以仅用于请求在2.4GHz和5GHz上进行认证、连接或重新连接。可选地，此时，2.4GHz和5GHz对应的所述请求位可以为1，60GHz对应的所述请求位可以为0。
在一种可能的实现方式中，所述第一帧可以包括至少两个第一元素，每个所述第一元素携带一个频段的所述请求位。
例如，所述至少两个频段可以包括2.4GHz、5GHz和60GHz，此时，所述第一帧可以包括两个第一元素，其中的一个第一元素可以与2.4GHz对应，用于携带2.4GHz的所述请求位，其中的另一个第一元素可以与5GHz对应，用于携带5GHz的所述请求位，其中的再一个第一元素可以与60GHz对应，用于携带60GHz的所述请求位。
可选地，2.4GHz对应的所述请求位和5GHz对应的所述请求位可以为1，用于请求在2.4GHz和5GHz上进行认证、连接或重新连接，60GHz对应的所述请求位可以为0，所述60GHz对应的请求位未请求在60GHz上进行认证、连接或重新连接。此时，所述60GHz对应的所述第一元素携带的信息可以用于指示所述第二设备在60GHz上的传输能力。
在一种可能的实现方式中，所述第一元素可以为多频段元素(multi-band element)。
可选地，如图3所示，当所述第一元素为多频段元素时，所述请求位可以位于多频段元素中的多频段控制域(multi-band control field)中的保留位中，或者所述请求位可以位于多频段元素中的多频段连接能力域(multi-band connection capability field)中，或者所述请求位可以位于保留位中或多频段元素中的新增的域中。
在另一种可能的实现方式中，所述第一元素可以为邻居报告元素(neighbor report  element)。
