背景技术
随着终端2048×1080分辨率(2048×1080 resolution，2K)视频和增强现实(augmented reality，AR)技术的发展与应用，视频流量的提升对移动智能终端的数据传输速率要求越来越高，无线保真(Wireless-Fidelity，WiFi)作为终端的主要流量接口之一，在室内应用场景下承担了大部分视频和AR流量传输，终端对WiFi流量要求日趋高涨。
相关技术中，双频无线路由器已经普及，双频无线路由器采用两种不同的工作频段，例如2.4G频段和5G频段，分别用两个不同服务集标识(Service Set Identifier，SSID)，不同终端分别通过2.4G或5G连接到路由器进行通信。相关技术中的终端在与路由器进行数据传输时只能单独关联一个工作频段，即只能单独关联2.4G或单独关联5G。也就是说，在环境中存在两个独立可连接SSID时，终端只能二选一进行通信，没有达到路由-终端的最大信道容量，极大浪费频谱资源。
发明内容
本公开提供一种终端及数据传输方法，以解决相关技术中在环境中存在两个独立可连接SSID，终端只能二选一进行通信的问题。

第二方面，本公开实施例提供一种数据传输方法，应用于第一终端，第一终端为上述的终端，包括：
建立第一终端与第一对端间的第一无线链路，以及，建立第一终端与第二对端间的第二无线链路；
通过第一通路和第一无线链路，在第一终端与第一对端间收发第一数据，以及，通过第二通路和第二无线链路，在第一终端与第二对端间收发第二数据。
第三方面，本公开实施例提供一种第一终端，第一终端为上述的终端，包括：
建立模块，用于建立第一终端与第一对端间的第一无线链路，以及，建立第一终端与第二对端间的第二无线链路；
收发模块，用于通过第一通路和第一无线链路，在第一终端与第一对端间收发第一数据，以及，通过第二通路和第二无线链路，在第一终端与第二对端间收发第二数据。
本公开实施例中，第一频段的射频信号和第二频段的射频信号可以分别通过第一通路和第二通路进行传输，并通过合路器能够实现第一通路和第二通路中射频信号上分别与天线之间的传输并避免两者之间的相互影响，从而能够实现第一频段和第二频段的发射和接收同时传输互不影响，实现两个通路可同时进行数据传输，即双频发射和接收之间互不影响。

在从信号调制模块30到合路器20的方向上，第二通路50中串接有工作频段为第二频段的第二收发机51。
本公开实施例中，终端可以包括天线10、合路器20、信号调制模块30以及第一通路40和第二通路50，其中，第一通路40可以包括第一收发器41，第二通路50可以包括第二收发器51；这里，天线10接收第一频段的射频信号，第一频段的射频信号经由合路器20传输至第一通路40，通过第一通路40中的第一收发器41将第一频段的射频信号进行变频和解调处理后，通过第一通路40传输至信号调制模块30；信号调制模块30将第一频段的射频信号传输至第一通路40，经由第一收发器41对第一频段的射频信号进行调制和变频处理后，通过第一通路40传输至合路器20，经由合路器20传输至天线，通过天线发射；同理地，天线10接收第二频段的射频信号，第二频段的 射频信号经由合路器20传输至第二通路50，通过第二通路50中的二收发器51将第二频段的射频信号进行变频和解调处理后，通过第二通路50传输至信号调制模块30；信号调制模块30将第二频段的射频信号传输至第二通路50，经由第二收发器51对第二频段的射频信号进行调制和变频处理后，通过第二通路50传输至合路器20，经由合路器20传输至天线10。其中，信号调制模块30可以为调制解调器(Modem)。
本公开实施例中，第一频段的射频信号和第二频段的射频信号可以分别通过第一通路40和第二通路50进行传输，并通过合路器20能够实现第一通路40和第二通路50中射频信号上分别与天线10之间的传输并避免两者之间的相互影响，从而能够实现第一频段和第二频段的发射和接收同时传输互不影响，实现两个通路可同时进行数据传输，即双频发射和接收之间互不影响。
可选地，在本公开一些实施例中，第一频段和第二频段均为WiFi射频信号的工作频段。有利地，本公开实施例中，第一频段可以为2.4G频段和5G频段中的一个，第二频段为2.4G频段和5G频段中的另一个。这样，由于2.4G频段和5G频段分属不同频段且相隔较远，可以很好共存，能够确保2.4G频段和5G频段的发射/接收(transmitting/receiving，TX/RX)同时传输互不影响。
其中，本公开实施例中，终端可以基于第一频段和第二频段分别与其他对端建立无线链路，并通过建立的无线链路分别与其他对端之间实现单独收发数据。例如，在一可选示例中，在一第一接入点具备工作频段为第一频段的第一接口和工作频段为第二频段的第二接口时，第一接口和第二接口分别为不同的对端，终端可以基于第一频段与第一接口建立第一无线链路，基于第二频段与第二接口建立第二无线链路。这里，可以实现终端同时独立关联第一接入点的双频SSID，从而对传输速率的提升。可选地，该第一接入点可以为路由器。
再例如，在一可选示例中，终端可以基于第一频段与第二接入点建立第一无线链路，同时，可以以终端作为接入点，基于第二频段与其他终端建立第二无线链路。这里，第二接入点和其他终端分别为不同的对端，终端可以通过将数据分开放在两个不同频段上传输，实现数据同时且互不影响地传输。 举例而言，第二接入点可以为路由器，此时，以终端作为接入点即可以为终端开启热点，也即，终端可以通过第一频段与路由器关联实现终端联网，并传输联网数据，同时可以通过采用第二频段开启热点组建局域网，实现终端与其他终端建立连接，并实现数据传输，例如，其他终端可以基于第二频段实现联网，或者，例如，其他终端可以基于第二频段实现终端投屏至其他终端。
在本公开一些可选的实施例中，为避免第一频段的射频信号在传输过程中发生信号波形变形，如图1和图2所示，第一通路40中还可以串接有带通频段为第一频段的第一带通滤波器42，第一带通滤波器42串接于第一收发机41与合路器20之间；从而利于抑制第一频段的射频信号在第一通路40中的传输干扰。
在本公开一些可选的实施例中，为避免第二频段的射频信号在传输过程中发生信号波形变形，如图1和图2所示，第二通路50中还可以串接有带通频段为第二频段的第二带通滤波器52，第二带通滤波器52串接于第二收发机51与合路器20之间；从而利于抑制第二频段的射频信号在第二通路50中的传输干扰。
可选地，请参见图2，在本公开一些实施例中，信号调制模块30可以包括：第一调制解调单元31，第一调制解调单元31与第一收发机41连接，用于对第一频段的射频信号进行调制处理或解调处理；以及，第二调制解调单元32，第二调制解调单元32与第二收发机51连接，用于对第二频段的射频信号进行调制处理或解调处理。这里，第一收发器41可以通过IQ线(即正交调制信号线)与第一调制解调单元31连接，在第一频段的射频信号经第一收发器41进行调制和变频处理后传输至第一调制解调单元31，通过第一调制解调单元31将接收的信号经模数转换器(Analog-to-Digital Converter，ADC)变换成数字信号，再进行数据解码，并最终呈现为软件可解析的表示协议数据单元(Presentation Protocol Data Unit，PPDU)帧进入七层模型(Open System Interconnection，OSI)，从而解析出媒体访问控制(Media Access Control，MAC)地址，得到互联网协议(Internet Protocol，IP)地址，其中，第一频段的射频信号的发射链路与第一频段的射频信号的接收链路相反，不再赘述；第二收 发器51可以通过IQ线与第二调制解调单元32连接，在第二频段的射频信号经第二收发器51进行调制和变频处理后传输至第二调制解调单元32，通过第二调制解调单元32将接收的信号变换成数字信号，再进数据解码，并最终呈现为软件可解析的PPDU帧进入七层模型，从而解析出MAC地址，得到IP地址，其中，第二频段的射频信号的发射链路与第二频段的射频信号的接收链路相反，不再赘述。
另外，本公开实施例中，该终端可以为手机或平板电脑。当然，该终端并不局限于手机和平板电脑，其可以为膝上型电脑(Laptop Computer)或个人数字助理(Personal Digital Assistant，PDA)等电子设备。
