Description

一种终端设备
本申请要求在2018年1月10日提交中国专利局、申请号为201810023903.X、发明名称为“一种终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种终端设备。
背景技术
载波聚合是LTE-A中的关键技术。为了满足单用户峰值速率和系统容量提升的要求，一种最直接的办法就是增加系统传输带宽。因此LTE-Advanced系统引入一项增加传输带宽的技术，也就是载波聚合(Carrier Aggregation，CA)。CA技术可以将2～5个LTE成员载波(ComponentCarrier，CC)聚合在一起，实现最大100MHz的传输带宽，有效提高了上下行传输速率。终端设备根据自己的能力大小决定最多可以同时利用几个载波进行上下行传输。
目前实现载波聚合通常会使用四工器或者六工器。四工器具有四个单向端口，一个双向端口。四个单向端口分别接通两路发射通路，两路接收通路，一个双向端口用于将两个频段的载波合路，并将接收的载波聚合信号分离，所以可以支持两个频段的载波同时工作，进而可以实现2CC的CA。类似的，六工器具有六个单向端口，一个双向端口。六个单向端口分别接通三路发射通路、三路接收通路，所以可以支持三个频段的载波同时工作，进而可以实现3CC的CA。
但是，采用传统的四工器或者六工器实现载波聚合时，经常会导致射频前端的插损较大，使得射频接收的传导性能降低，且实现载波聚合的成本较高。
因此，目前亟需一种终端设备，在提高通信质量的同时，降低成本，提 高产品竞争力。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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描述。
本申请实施例提供的一种终端设备的结构示意图。该终端设备例如可以是移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(英文：Personal Communication Service；简称：PCS)电话、无绳电话、会话发起协议(英 文：Session Initiation Protocol；简称：SIP)话机、无线本地环路(英文：Wireless Local Loop；简称：WLL)站、个人数字助理(英文：Personal Digital Assistant；简称：PDA)等设备。无线终端设备也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)。
请参考图1所示，为本申请实施例提供的一种终端设备的结构图。需要说明的是，在图1中的实施例中，第一发射支路以2个为例，多个第一发射支路的情况与此类似，在此不再赘述。
终端设备包括：第一天线101、第二天线102、与第一天线101电连接的第一通道、与第二天线102电连接的第二通道；
所述第一通道包括至少两条第一发射支路112-113，第一发射支路112-113用于通过第一天线101发送实现载波聚合的载波信号；
所述第二通道包括与第二天线102电连接的接收支路122及与接收支路122电连接的接收滤波器123，接收支路122用于通过第二天线102接收载波聚合信号，接收滤波器123用于对所述载波聚合信号进行滤波，得到实现载波聚合的载波信号。
接收滤波器123为带通滤波器。接收滤波器123允许通过的载波的频段与接收支路122所接收的载波的频段一致。
在具体实施过程中，所述第一通道包括开关电路104，开关电路104的一端述第一天线101电连接，开关电路104的另一端与第一发射支路112-113电连接；
开关电路104可以具有多个输入端口和一个输出端口。所述多个输入端口用于导通第一发射支路112-113中相同频段的发射支路。所述输入端口的数量根据实际需求来定，例如，实际需求可能只需要实现2个频段的载波聚合即可，所以如果是实现2个频段的下行载波聚合的话，那么就只需要同时 导通两个频段中的一个频段的发射支路即可，此时，开关电路104只要具有2个输入端口即可。在实际运用中，为了便于后续载波聚合的数量的扩展，开关电路104的输入端口的数量可以设计多个候选输入端口。一个输出端口与第一天线101或第一天线101的后端电路连接。
一种可能的实现方式，所述终端设备还包括：控制器，用于控制所述开关电路的另一端与第一发射支路112-113之间的导通状态。
第一天线101和第二天线102可以包括天线本体和天线后端电路，当然，第一天线101和第二天线102也可以只是天线本体。第一天线101和第二天线102可以用于将载波调制信号辐射至空间中及接收空间中的电磁波。
可选的，如图1所示，本实施例中的终端设备还可以包括射频集成电路(英文：Radio Frequency Integrated Circuit，简称：RFIC)。当然，在实际运用中，RFIC可以是单独的元器件。RFIC用于将上行数据调制在载波上，形成载波调制信号，以及用于将接收到的载波调制信号进行解调，获得下行数据。
第一发射支路112-113中包括发射滤波器212-213，发射滤波器212-213的一端与开关电路104的另一端电连接，发射滤波器212-213的另一端与射频芯片103电连接。发射滤波器为带通滤波器。发射滤波器允许通过的载波的频段与该发射支路所发射的载波的频段一致。第一发射支路112包括一个发射滤波器212，发射滤波器212允许第一频段的载波通过，所以第一发射支路112用于发射第一频段的载波调制信号。第一发射支路113包括一个发射滤波器213，发射滤波器213允许第二频段的载波通过，所以第一发射支路113用于发射第二频段的载波调制信号。所述第一频段和所述第二频段为实现载波聚合的载波信号。所述第一频段和所述第二频段互不相同。
如图2所示，本申请实施例中，第一发射支路112-114中包括发射滤波器212-214，发射滤波器212-214的一端与开关电路104的另一端电连接，发射滤波器212-214的另一端与射频芯片103电连接。发射滤波器为带通滤波器。发射滤波器允许通过的载波的频段与该发射支路所发射的载波的频段一 致。
一种可能的实现方式，第一发射支路114包括所述第一频段和所述第二频段的二合一发射滤波器214，所以第一发射支路允许所述第一频段和所述第二频段的载波通过。
另一种可能的实现方式，第一发射支路114中包括2个独立的发射滤波器通过双工器与开关电路104的另一端电连接，用于实现上行载波聚合。此处的双工器用于将所述第一频段和所述第二频段的载波合路为一个频段的载波。
需要说明的是第一发射支路114可以根据实际需要进行添加或删除，或用户只需要下行载波聚合，可以不设置第一发射支路114，若需要进行上行载波聚合，可以添加第一发射支路114，在此不做限定。
综上所述，当发射滤波器均为独立的滤波器时，第一发射支路的个数与载波聚合的频段数相同。当发射滤波器中包括多合一滤波器和/或二合一滤波器时，第一发射支路的个数大于载波聚合的频段数相同。如果发射滤波器可以实现将所有载波聚合的频点数合一的滤波器时，发射滤波器可以为一个。
需要说明的是，两个频段互不相同指的是两个频段所覆盖的频率范围不重叠，而两个频段所覆盖的频率宽度可以相同，也可不同。举例来说，第一频段的频率范围为780MHz至800MHz，频率宽度为20MHz。第二频段的频率范围为960MHz至980MHz，频率宽度为20MHz。
接收支路122及与接收支路122电连接的接收滤波器123，接收支路122用于接收载波聚合信号，接收滤波器123用于将所述载波聚合信号过滤为实现载波聚合的各载波信号。例如，接收支路122接收所述载波聚合的第一频段和第二频段的载波聚合信号，接收滤波器123可以为二合一的接收滤波器，将所述载波聚合信号第一频段的载波信号和第二频段的载波信号分别传输至射频芯片。
为提升接收性能，通过第一天线和第二天线同时接收所述载波聚合的载波信号，用于获得增强的所述载波信号。具体的，可以通过接收支路和第一 发射支路接收到所述载波聚合的所述第一频段或所述第二频段的载波信号。
在具体实施过程中，可以在至少一条第一发射支路中包括双工器，所述双工器的一端与所述开关电路的另一端电连接，所述双工器的另一端与射频芯片电连接；所述至少一条第一发射支路还用于接收载波聚合的载波信号。
一种可能的实现方式，所述终端设备还包括：巴伦；
所述巴伦的第一输入端与所述至少一条第一发射支路中的双工器电连接，所述巴伦的第二输入端与所述第二通道中的接收滤波器电连接，所述巴伦的输出端与射频芯片103电连接；
所述巴伦，用于将所述至少一条第一发射支路和所述第二通道接收的实现载波聚合的同一载波信号合并为增强的载波信号。
当然，也可以在多个第一发射支路中包括双工器，用于获得多个增强的所述载波聚合的载波信号。具体过程与获得一个增强的载波信号类似，在此不再赘述。
由上面描述可以看出，本申请实施例中采用发射滤波器，用于发射载波聚合的载波信号，增加一个第二天线，所述第二天线包括接收滤波器，用于接收所述载波聚合信号，实现上行CA或下行CA；避免使用四工器等高成本元件，结构简单，设计难度小。并且在所述第二通道中，避免使用开关电路，减少插损，提升通信性能。
本申请实施例中的终端设备可以通过以下方式发射和接收所述单载波信号：
所述第一发射支路还用于接收单载波信号；所述单载波信号与至少一个所述载波聚合的载波信号的频段重叠。
例如，若确定所述单载波信号的发射频段与所述载波聚合的第一频段的发射频段相同，则通过第一发射支路112发射所述单载波信号。
一种可能的实现方式，如图3所示，所述第一通道还包括第二发射支路115，第二发射支路115与开关电路104的另一端电连接，第二发射支路115用于发送单载波信号。
接收支路122还用于接收单载波信号；所述单载波信号与至少一个所述载波聚合的载波信号的频段重叠。
例如，若确定所述载波聚合的第一频段的接收频段与所述非载波聚合的接收频段重叠，则将所述接收支路122用于接收所述单载波信号；具体的，可以通过所述接收支路122中的接收滤波器接收所述单载波信号，并通过可以接收所述频段的接收滤波器的输出端口传输至射频芯片103。
一种可能的实现方式，第二发射支路115包括双工器；所述双工器的一端与所述开关电路的另一端电连接，所述双工器的另一端与射频芯片103电连接，第二发射支路115还用于接收单载波信号。
例如，若确定所述载波聚合中的所有频段的接收频段与所述单载波信号的接收频段互不相同，则通过第一天线101接收所述单载波信号，并通过第二发射支路115中的双工器，传输所述单载波信号至射频芯片。
一种可能的实现方式，所述终端设备还包括：控制器，用于控制所述开关电路的另一端与第一发射支路112-113及第二发射支路115之间的导通状态。
由上可以看出，本申请实施例，不仅可以实现CA，还可以通过导通一个频段的第一发射支路或第二发射支路和接收支路，实现单载波的数据传输。因此，本发明实施例中的终端设备可以兼容单载波传输和CA传输。
可选的，所述第一发射支路或所述第二发射支路还包括功率放大器(英文：Power Amplifier，简称：PA)。PA设置在射频芯片103和发射滤波器之间。
在具体实施过程中，所述第一发射支路中的发射滤波器和/或双工器通过功率放大器与射频芯片103电连接；所述第二发射支路中的双工器通过所述功率放大器与射频芯片103电连接。
PA用于对射频芯片103调制成的载波调制信号进行功率放大，以达到需求的发射功率。
以上举例描述了第一发射支路、第二发射支路和接收支路可能的构成， 在实际运用中，第一发射支路、第二发射支路和接收支路还可以包括其它元器件，只要不影响CA即可。
可选的，为了保证整个通路的可靠性要求，第一发射支路和第二发射支路上的发射滤波器的功率承受能力容限需要满足该第一发射支路和第二发射支路的发射功率要求。举例来说，第一发射支路的发射功率需要达到50瓦(W)，那么第一发射支路对应的发射滤波器的功率承受能力容限就需要达到50W。
以下将举两个具体的实例来说明本发明实施例中终端设备的实施过程。
请参考图2所示，在本实施例中，第一接收支路112-114中包括发射滤波器212-214，假设载波聚合的2个频段分别为B1频段和B3频段。在B1频段的单载波的情况下，开关电路104的输入端口与B1频段对应的第一发射支路112导通，接收支路接收B1频段。而在B3频段的单载波的情况下，开关电路的输入端口与B3频段对应的第一发射支路113导通，接收支路接收B1频段。假设在某一时刻，基站下发指示信息给终端设备，指示B1频段为主频段，B1频段和B3频段为下行CA时，第一天线101中的开关电路104的输入端口导通第一发射支路112，进而通过第一天线101发射B1频段的载波信号，第二天线102的接收支路122接收B1频段和B3频段的载波聚合的载波信号。再例如，假设在某一时刻，基站下发指示信息给终端设备，指示B1频段为主频段，B1频段和B3频段为上行CA时，开关电路104的输入端口导通第一发射支路114，进而通过第一天线101发射B1频段和B3频段的载波聚合的载波信号，第二天线102的接收支路122接收B1频段的载波信号。

举例来说，终端设备以图2所示的结构为例，假设当前终端设备工作在单载波模式，且使用的是B1频段的载波。那么基站可以通过B1频段的载波下发指示信息给终端设备。指示信息指示使用B1频段和B3频段进行下行CA。终端设备的所述处理器或者所述控制器解析指示信息，获知需要使用B1频段和B3频段进行下行CA。因此所述控制器就控制开关电路104的输入端口导通B1频段或B3频段对应的第一发射支路。通过第二天线接收所述B1频段和B3频段。
至于具体是第一发射支路为接收B1频段或B3频段，可以任选一个，还可以是在指示信息中还可以指示步骤101中的至少两个频段中的主频段，那么同时导通的第一发射支路即为主频段对应的第一发射支路。在本例中，假设指示B1频段为主频段，那么同时导通的为B1频段的第一发射支路。
如果指示信息指示的是B1频段和B3频段做上行CA时，所述控制器控制开关电路的输入端口导通B1频段和B3频段合频后对应的第一发射支路114。在图2所示的例子中，B1频段和B3频段使用的是二合一发射滤波器，所以对应的均为发射支路。因此，最终同时导通的是B1频段和B3频段合频后第一发射支路以及接收支路。
在实际运用中，所述步骤一还有另一种实施方式，详细来说，所述步骤一包括：根据实际需求确定所述至少两个频段。举例来说，假设当前终端设备需要传输的数据较大，所以确定需要进行上行CA，然后根据需要的传输带宽确定需要哪几个频段进行上行CA。其余与网络侧设备发送指示信息的情况类似，所以不再赘述。
