Description

一种终端设备 技术领域
本发明涉及一种通信设备，特别涉及一种终端设备。
背景技术
长期演进(Long Term Evolution，简写为：LTE)通信技术在全球已经较为普及，但是，现代移动通信标准继续需要提高数据的传输速率。对于终端设备来说，例如，手机或具有通信功能的平板电脑等，其中一个重要的提高数据传输速率的方式是载波聚合(Carrier Aggregation，简写为：CA)。载波聚合允许单个的终端设备将多个成员载波(Component Carrier，简写为：CC)聚合在一起，实现最大的传输带宽，以达到最大的传输速率。
参见表1，表1描述了在无线通讯环境下使用的成员载波的频率带宽。在实际通信过程中，一个支持CDMA、GSM、LTE和/或LTE-Advanced的终端设备可能同时使用一个或多个成员载波进行数据传输。表1中左边的第一列表示每个成员载波的代号，第二列和第三列表示每个相应成员载波的上行和下行频率带宽，第四列表示相应的每个成员载波的双工模式。在非载波聚合的场景下，终端设备用单个成员载波进行通信；在载波聚合的场景下，终端设备可能聚合多个成员载波进行通信，予以提高终端设备的数据传输速率。

参见附图1，附图1描述了现有技术中，支持载波聚合的终端设备常用的射频前端电路。该射频前端电路包括双频合路器2，四工器3和四工器4；其中，双频合路器2一端连接到天线1，双频合路器2用于频带间载波聚合，并将合成后的信号通过天线1发送出去；四工器3和四工器4用于频带内载波聚合，并将合成后的信号发送至双频合路器2，双频合路器2进一步对四工器3和四工器4传输来的信号进行频带间载波聚合，并将聚合后的信号通过天线1发送出去。
由于双频合路器1本身具有插损，特别的，在处理高频信号的情况下，插损极大。另外，对于同时支持频带内载波聚合和频带间载波聚合的射频前端电路而言，待发送信号面临四工器3或四工器4及双频合路器2带来的二级插损，当终端设备工作在非载波聚合模式下时，其传输的信号会遭受插损带来的巨大影响，进而降低信号传输质量，导致数据传输时间过长，最终影响用户体验。
发明内容

本发明实施例提供一种终端设备，包括，控制电路5和天线1，终端设备还包括：合路器2，天线开关6，信号切换开关3和信号切换开关4，控制电路5分别和天线开关6，信号切换开关3和信号切换开关4连接；信号切换开关3的输出端口E连接到天线开关6的输入端口A；信号切换开关3的输出端口D连接到合路器2的输入端口Z4，信号切换开关4的输出端口Y连接到天线开关6的输入端口C；信号切换开关4的输出端口X连接到合路器2的输入端口Z4； 天线开关6的输出端Z2连接到所述天线1；天线开关6的输入端口A连接到信号切换开关3的输出端口E；天线开关6的输入端口C连接到信号切换开关4的输出端口Y；天线开关6的输入端口B连接到合路器2的输出端口Z3。
本发明实施例识别终端设备工作在非载波聚合模式时，通过为传输信号建立一条不经过具有高插损器件的通路，能够有效避免插损问题，提高信号传输质量。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。
图1为现有技术中，支持载波聚合的终端设备常用的射频前端电路结构示意图；
图2为本发明实施例提供的一种终端设备结构示意图；
图3为本发明实施例提供的另一种终端设备结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其它实施例，都属于本发明保护的范围。
实施例一
参考附图2，其为本发明提供的第一个实施例。如附图2所示，终端设备包括，控制电路5和天线1，终端设备还包括：合路器2，天线开关6，四工器3和四工器4；控制电路5分别和天线开关6，四工器3和四工器4连接；天线开关6的输出端Z2连接到天线1，天线开关6的输入端口A连接四工器3的输出端口Z，天线开关6的输入端口C连接四工器4的输出端口Z1，天线开关6的输入端口B连接所述合路器2的输出端口Z3；合路器2的输入端口Z5连接到四工器3的输出端口Z；合路器2的输入端口Z4连接到四工器4的输出端口Z1。
本发明实施例识别终端设备工作在非载波聚合模式时，通过为待传信号建立一条不经过具有高插损器件的通路，能够有效避免插损问题，提高信号传输 质量。
需要说明的是，合路器2可以为双频合路器或三频合路器。
还需要说明的是，合路器2的输入端口Z5和输入端口Z4可以集成为一个端口。
本实施例既可以用在终端设备处于载波聚合的场景下，也可以用在终端设备处于非载波聚合的场景下。现在举例说明如下：
具体的，当终端设备处于载波聚合的场景下时，控制电路5识别终端设备处于载波聚合工作模式，并且需要进行频带间载波聚合时，控制天线开关6接通端口B，使四工器3和四工器4各自接受到的信号能够送到双频合路器2处进行频带间载波聚合，聚合后的信号通过天线开关6到达天线1，并经过天线1发射出去。
当终端设备处于非载波聚合的场景下时，控制电路5识别终端设备处于非载波聚合工作模式，控制天线开关6接通端口A或C，四工器3或四工器4接受到的信号能够通过天线开关6直接到达天线1，并经过天线1发射出去，这样避免了，当终端设备在非载波聚合工作模式时，信号依然需要通过双频合路器2的问题，避免了双频合路器2带来的插损的问题。此处，需要说明的是，四工器3或四工器4可以根据实际的需要，接受不同频段的信号，例如，可以设置四工器3专用于接收高频信号，四工器4专门用于接收低频信号。此处，还需要说明的是，高频信号和低频信号是一个相对的概念，本发明并不加以限定，以本领域技术人员的通常使用常识为参考。
参考表1的载波频率，例如，四工器3接收到载波频率为3400KHZ的上行载波信号，控制电路5识别终端设备处于非载波聚合工作模式，则控制天线开关6接通端口A，载波信号则可以直接经过天线开关6到达天线1，并经过天线1发射出去。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
实施例二
参考附图3，其为本发明提供的另一个实施例。如附图3所示，终端设备包括，
控制电路5和天线1，终端设备还包括：合路器2，天线开关6，信号切换开关3和信号切换开关4，控制电路5分别和天线开关6，信号切换开关3和信号切换开关4连接；信号切换开关3的输出端口E连接到天线开关6的输入端口A；信号切换开关3的输出端口D连接到合路器2的输入端口Z4，信号切换开关4的输出端口Y连接到天线开关6的输入端口C；信号切换开关4的输出端口X连接到合路器2的输入端口Z4；天线开关6的输出端Z2连接到所述天线1；天线开关6的输入端口A连接到信号切换开关3的输出端口E；天线开关6的输入端口C连接到信号切换开关4的输出端口Y；天线开关6的输入端口B连接到合路器2的输出端口Z3。
本发明实施例识别终端设备工作在非载波聚合模式时，通过为待传信号建立一条不经过具有高插损器件的通路，能够有效避免插损问题，提高信号传输质量。
需要说明的是合路器2可以为双频合路器或三频合路器。
还需要说明的是，信号切换开关3和信号切换开关4均为双刀多掷开关。
本实施例既可以用在终端设备处于载波聚合的场景下，也可以用在终端设备处于非载波聚合的场景下。现在举例说明如下：
具体的，本实施例提供的射频前端电路的工作环境如附图3所揭示，包括：天线1，天线开关6，控制电路5，双频合路器2，双刀多掷开关3和双刀多掷开关4。控制电路5在本实施例中的作用包括控制天线开关6和双刀多掷开关3和双刀多掷开关4；双频合路器2用于对双刀多掷开关3和双刀多掷开关4处传输过来的信号进行合路处理。
参考表1的载波频率，举例对本实施例进行说明。若双刀多掷开关3的输入接口G，H，I，J，K，L，M和N设置接收高频信号，双刀多掷开关4的输入接口O，P，Q，R，S，T，U和V设置接收低频信号，需要注意的是：本实施例中，所谓的高频信号和低频信号是一个相对的概念，并无绝对的数值予以区分，在实际使用环境中，设计人员可以根据实际情况设置双刀多掷开关3和双刀多掷开关4的频率工作范围。
当终端设备处于载波聚合的场景下时，例如，双刀多掷开关3的K输入端口接收到频率为2300KHZ的载波信号，双刀多掷开关4的U端口接收到频率为840KHZ的载波信号，
控制电路5识别终端设备处于载波聚合工作模式，并且载波信号需要进行频带间载波聚合时，控制电路5控制天线开关6接通端口B，并且控制电路5控制双刀多掷开关3接通其输出端口D和输入端口K的连接，控制电路5还控制双刀多掷开关4接通其输出端口X和输入端口U的连接，使得两路载波信号能够达到双频合路器2，并在双频合路器2处进行载波聚合，被聚合后的信号通过天线开关端口B，到达天线1，进而被发送出去。
当终端设备处于非载波聚合的场景下时，例如，双刀多掷开关3的K输入端口接收到频率为2300KHZ的载波信号，控制电路5识别终端设备处于非载波聚合工作模式，载波信号无需进行频带间载波聚合时，控制电路5控制天线开关6接通端口A，控制电路5还控制双刀多掷开关3接通其输出端口E和输入端口K的连接，这样，载波信号直接通过双刀多掷开关3接通其输出端口E，经过天线开关端口A，到达天线1，进而被发送出去。如此，该信号在非载波聚合的工作模式下，旁路掉了双频合路器带来的插损，保证了信号的质量。上述描述的双刀多掷开关3的工作模式同样适用双刀多掷开关4。
另外还需要说明的是：上述实施例中的双频合路器2可以改成为三频合路器。若改为三频合路器的话，则相应的，需要适配三个双刀多掷开关，每个双刀多掷开关可以设置为接收不同频率的信号，例如，可以设置第一个双刀多掷开关接收低频信号，第二个双刀多掷开关接收中频信号，第三个双刀多掷开关接收高频信号。同样的，低频信号，中频信号和高频信号都是相对的概念，在实际使用环境中，设计人员可以根据实际情况设置。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
