具体实施方式
本申请实施例涉及的术语“第一”、“第二”等仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元。方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
应当理解，在本申请中，“至少一个(项)”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，用于描述关联对象的关联关系，表示可以存在三种关系，例如，“A和/或B”可以表示：只存在A，只存在B以及同时存在A和B三种情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，“a和b”，“a和c”，“b和c”，或“a和b和c”，其中a，b，c可以是单个，也可以是多个。
对于一个支持4G和5G双制式同时收发的终端设备来说，为了保证4G与5G通路上的射频器件可以同时工作，终端设备可以分别设置4G射频前端通路和5G射频前端通路。4G射频前端通路包括多个射频前端器件，例如多工器或滤波器等。5G射频前端通路包括多个射频前端器件，例如多工器或滤波器等。4G射频前端通路和5G射频前端通路相互独立，以支持不同频段的4G射频信号和不同频段的5G射频信号的发送。与分别设置4G射频前端通路的射频前端器件和5G射频前端通路的射频前端器件不同，本申请实施例提供的射频前端模块中设置有频段选择电路，通过该频段选择电路可以将相同频段的第一射频信号和第二射频信号路由至相同的滤波器和/或多工器，从而实现第一射频前端通路和第二射频前端通路共用滤波器和/或多工器，以减少射频前端的滤波器、多工器等器件，进而减少射频前端模块所占用的空间。其中，多工器可以包括双工器、三工器、或四工器等，本申请实施例的射频前端模块的具体结构可以参见下述实施例的解释说明。
本申请实施例所涉及的第一射频信号和第二射频信号可以是不同制式的射频信号，例如，第一射频信号为4G射频信号，第二射频信号为5G射频信号。第一射频信号和第二射频信号也可以是相同制式但频段不同的射频信号。第一射频信号和第二射频信号还可以是终端设备使用不同SIM与接入网设备通信的射频信号。
本申请实施例的5G射频信号的频段可以是Sub6G，即7.2GHz以下的频段。本申请 实施例的4G射频信号的频段可以是Sub3G，即3GHz以下的频段。由此可见，5G射频信号的频段和4G射频信号的频段存在重叠，即3GHz以下的频段重叠。3GHz以下的频段可以包括低频频段(low frequency band，LB)、中频频段(middle frequency band，MB)和高频频段(high frequency band，HB)。其中，LB为1000Mhz以下的频段，MB为1.7～2.3Ghz的频段，HB为2.3～2.7Ghz的频段。LB和MB可以构成LMB，MB和HB可以构成MHB。
为了方便描述，本申请实施例将2.7Ghz～7.2GHz称为5G高频频段。
5G频率范围被划分为不同频段，不同频段对应不同的频段号，例如，N41、N7等。4G频率范围被划分为不同频段，不同频段对应不同的频段号，例如，B41、B7等。N41和B41对应的频率范围相同。
上述LB可以包括N28A、B28A、N28B、B28B、N20、B20、N8、B8等。上述MB可以包括N1、B1、N3、B3等。上述HB可以包括N41、B41、N40、B40、N7、B7等。
一种示例，本申请实施例提供的射频前端模块可以应用于图1所示的通信系统中的终端设备3中，该通信系统可以为采用NSA模式部署的双连接的通信系统，例如，LTE-NR的双连接。LTE-NR的双连接可以包括EN-DC(E-UTRA-NR Dual Connectivity)、NGEN-DC(NG-RAN E-UTRA-NR Dual Connectivity)、或NE-DC(NR-E-UTRA Dual Connectivity)。
其中，EN-DC指核心网接入4G核心网(Evolved Packet Core，EPC)，4G基站作为主基站(Master eNB，MeNB)，5G基站作为辅基站(Secondary eNB，SeNB)。NGEN-DC指核心网接入5G核心网(5G Core，5GC)，4G基站作为MeNB，5G基站作为SeNB。NE-DC指核心网接入5GC，5G基站作为MeNB，4G基站作为SeNB。
需要说明的是，随着通信技术的发展，上述NSA模式部署的双连接还可以是其他的双连接形式，例如，NR和未来下一代通信技术(例如，6G)的双连接，或者，4G和未来下一代通信技术(例如，6G)的双连接等，本申请实施例不以LTE-NR的双连接作为限制。换言之，本申请实施例的射频前端模块可以应用于同时与不同制式的接入网设备通信的终端设备。
当然可以理解的，本申请实施例的射频前端模块也可以应用于同时与同一制式的不同接入网设备通信的终端设备。
如图1所示，该通信系统可以包含：终端设备3，接入网设备1和接入网设备2。其中，图1中的终端设备3是指具备双连接能力的终端设备，主要用于通过空口连接到运营商部署的至少一个接入网设备上接收网络服务。容易理解，具备支持双连接能力的终端设备通常需要设置有支持与两个相同或不同制式的接入网设备通信的两路射频收发通路。接入网设备主要用于实现无线协议栈功能、资源调度和无线资源管理、无线接入控制以及移动性管理功能等。
例如，在第5代(5th generation，5G)系统部署的第一阶段，往往会选择5G NR的非独立组网方式，例如基于option3x或option3架构的EN-DC通信系统。示例性地，在EN-DC通信系统中，接入网设备1可以为长期演进(long term evolution，LTE)系统中的演进型节点(evolved Node B，eNB)，接入网设备2可以为NR系统中g节点(gNode B，gNB)，终端设备可以同时与eNB和gNB通信。
其中，上述接入网设备可以为具有无线收发功能的接入网设备或设置于接入网设备中 的芯片。该接入网设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base stationcontroller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，homeevolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
上述终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、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、用户代理或用户装置。本申请的实施例中的终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmentedreality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(selfdriving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smartgrid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smartcity)中的无线终端、智慧家庭(smart home)中的无线终端、智能手表、智能手环，智能眼镜，以及其他运动配件或可穿戴设备等等。本申请的实施例对应用场景不做限定。
需要说明的是，图1仅为示例性架构图，除图1中所示功能单元之外，该通信系统还可以包括其他功能单元，本申请实施例对此不进行限定。
另一种示例，本申请实施例提供的射频前端模块还可以应用于与同一接入网设备中的不同小区通信的终端设备，换言之可以应用于与采用载波聚合(Carrier Aggregation，CA)技术的接入网设备通信的终端设备。例如，CA可以是LTE的CA，也可以是5G的CA，或者也可以是其他制式的CA，本申请实施例不作限定。
又一种示例，本申请实施例提供的射频前端模块还可以应用于多卡终端设备，例如，双卡双待(Dual Sim Dual Standby，DSDS)终端设备，或双卡双通(Dual Sim Dual active，DSDA)终端设备。以DSDS终端设备为例，该DSDS终端设备可以设置两张用户身份识别模块(subscriber identification modula，SIM)卡，并且这两张SIM卡均处于待机状态，用户可以使用两张SIM卡进行拨打、接听电话、收发短信和访问各种应用程序(例如，视频播放类应用程序、即时通信类应用程序、游戏类应用程序)等操作。其中，任意一个SIM卡也可以替换为嵌入式SIM(Embedded-SIM，eSIM)卡。举例而言，用户可以使用一个SIM卡与LTE系统的eNB通信，使用另一个SIM卡与NR系统的gNB通信。需要说明的是，对于DSDS，用户使用一个SIM卡访问游戏类应用程序，在访问游戏类应用程序过程中，终端设备接收到另一个SIM卡的语音业务请求，这时，终端设备的游戏类应用程序会中断与服务器的连接。而与DSDS不同，对于DSDA，在上述场景中，终端设备的游戏类应用程序不会中断与服务器的连接，用户可以使用两个SIM卡一边玩游戏一边进行语音业务。
下面结合图2对上述终端设备的各个构成部件进行具体的介绍。
示例性的，图2为本申请实施例提供的一种终端设备200的结构示意图，如图2所示，该终端设备200可以包括处理器210、射频前端模块(Radio Frequency Front End Module，RFFEM)220、射频前端供电模块230以及天线模块240。

基带是指用来合成即将发射的基带信号，或/和用于对接收到的基带信号进行解码。具体地说，就是发射时，基带把语音或其他数据信号编码成用来发射的基带信号(基带码)；接收时，把收到的基带信号(基带码)解码为语音或其他数据信号。基带可以包括编码器、解码器和基带处理器等部件。编码器用来合成即将发射的基带信号，解码器用于对接收到的基带信号进行解码。基带处理器可以为微处理器(MCU)，基带处理器可以用于控制编码器和解码器，例如，基带处理器可以用于完成编码和解码的调度，编码器和解码器之间的通信，以及外设驱动(可以通过向基带以外的部件发送使能信号，以使能基带以外的部件)等等。
调制解调处理器可以包括调制器和解调器。其中，调制器用于将待发送的基带信号调制成基带调制信号。解调器用于将接收的基带调制信号解调为基带信号。随后解调器将解调得到的基带信号传送至基带处理。基带信号经基带处理后，被传递给应用处理器。应用处理器通过音频设备(不限于扬声器，受话器等)输出声音信号，或通过显示屏194显示图像或视频。在一些实施例中，调制解调处理器可以是独立的器件。在另一些实施例中，调制解调处理器可以独立于处理器210，与射频前端模块220或其他功能模块设置在同一个器件中。
射频收发器用于将调制解调器输出的基带调制信号上变频为射频(Radio Frequency，RF)信号，并将RF信号输出至射频前端模块220，以便之后由天线模块240中的一个或多个天线发射。射频收发器还用于将通过天线模块240和射频前端模块220接收到的RF信号，下变频为基带调制信号，以便之后由调制解调器和基带进行处理。在一些实施例中，射频收发器可以是独立的器件。在另一些实施例中，射频收发器可以独立于处理器210，与射频前端模块220或其他功能模块设置在同一个器件中。
