Description

射频电路和控制方法
本申请要求于2021年05月11日提交中国国家知识产权局、申请号为202110512135.6、申请名称为“射频电路和控制方法”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
本申请涉及终端技术领域，尤其涉及一种射频电路和控制方法。
背景技术
目前，第五代移动通信技术(5th-generation，5G)网络可以采用两种组网方式进行通信。两种组网方式分别为非独立组网(non-standalone，NSA)和独立组网(standalone，SA)。具体的，当双模5G手机支持NSA和SA两种模态时，双模5G手机可以通过多种方式实现通信。通信方式包括：5G新空口(new radio，NR)通信、长期演进(long term evolution，LTE)通信，以及LTE和NR的双连接(EUTRA-NR dual connectivity，ENDC)通信。在NR频段，双模5G手机还需要支持NR的1发4收(1T4R)的探测参考信号(sounding reference signal，SRS)天线轮流发射。
现有设计中，当NR需要4*4的多输入多输出(multiple-input multiple-output，MIMO)通信，LTE需要2*2 MIMO时，双模5G手机中包括6根天线。
但是，双模5G手机中的天线数量多，占用的空间大。

具体实施方式
为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一设备和第二设备仅仅是为了区分不同的设备，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
需要说明的是，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例的射频电路可以应用于具有通信功能的电子设备中。电子设备包括终端设备，终端设备也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、智能电视、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city) 中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
目前，NR通信需要4*4 MIMO，LTE需要2*2 MIMO。当终端设备支持NSA模态和SA模态时，终端设备需要支持LTE通信和NR通信，以及LTE和NR的双连接(EUTRA-NR dual connectivity，ENDC)通信。因此，终端设备中通常包括6根天线。
示例性的，图1为可能的实现中一种射频电路的结构示意图。如图1所示，射频电路中包括：射频收发器101、控制器102、开关一103、开关二104、天线一105、天线二106、天线三107、天线四108、天线五109和天线六110。
其中，射频收发器101用于输出LTE信号和/或NR信号，以及对一个或多个天线接收的LTE信号和/或NR信号进行信号处理。信号处理包括但不限于变频、解调和模数转换等。射频收发器101包括6个端口，其中，第一端口101A用于发射和接收LTE信号；第二端口101B用于接收LTE信号；第三端口101C用于发射和接收NR信号；第四端口101D用于接收NR信号；第五端口101E用于接收NR信号；第六端口101F用于接收NR信号。
控制器102用于控制开关一103和开关二104的设置，进而控制天线一105或天线二106发射LTE信号，以及控制天线三107、天线四108、天线五109或天线六110发射NR信号。
开关一103包括4个端口。开关一103的第一端口103A和第二端口103B分别与射频收发器101的第一端口101A和第二端口101B连接；开关一103的第三端口103C和第四端口103D分别与天线一105和天线二106连接。

开关一103和开关二104均与控制器102连接。
天线一105和天线二106用于发射和/或接收LTE信号。天线三107、天线四108、天线五109和天线六110用于发射和/或接收NR信号。
可能的实现方式一中，天线一105和天线二106的天线支持的频段范围均为824兆赫兹(MHz)-2170MHz，天线三107、天线四108、天线五109和天线六110支持的频段范围均为2496MHz-2690MHz。
可能的实现方式二中，天线一105和天线二106的天线支持的频段范围均为1710MHz-2690MHz，天线三107、天线四108、天线五109和天线六110支持的频段范围均为3300MHz-5000MHz。
可能的实现方式三中，天线一105和天线二106的天线支持的频段范围均为1710MHz-2690MHz，天线三107、天线四108、天线五109和天线六110支持的频段范围均为730MHz-803MHz。
上述射频电路，可以实现LTE通信、NR通信和ENDC通信。
控制器102通过控制开关一103的端口之间的连接，实现LTE通信。示例性的， 控制器102可以控制开关一103的第一端口103A和第二端口103B分别与开关一103的第三端口103C和第四端口103D连接。这样，射频收发器101的第一端口101A输出的LTE信号，经开关一103在天线一105发射。天线一105接收的LTE信号经开关一103从射频收发器101的第一端口101A进入射频收发器101中。天线二106接收的LTE信号经开关一103从射频收发器101的第二端口101B进入射频收发器101中。
控制器102通过控制开关二104的端口之间的连接，实现NR通信。示例性的，控制器102可以控制开关二104的第一端口104A、第二端口104B、第三端口104C和第四端口104D分别与开关二104的第五端口104E、第六端口104F、第七端口104G和第八端口104H连接。这样，射频收发器101的第三端口101C输出的NR信号，经开关二104在天线三107发射。天线三107接收的LTE信号经开关二104从射频收发器101的第三端口101C进入射频收发器101中。天线四108接收的LTE信号经开关二104从射频收发器101的第四端口101D进入射频收发器101中。天线五109接收的LTE信号经开关二104从射频收发器101的第五端口101E进入射频收发器101中。天线六110接收的LTE信号经开关二104从射频收发器101的第六端口101F进入射频收发器101中。
LTE通信和NR通信使用的开关和天线不同，当终端设备处于ENDC通信时，LTE信号和NR信号互不干扰。
但是，上述射频电路中包括6根天线，天线数量多，占用的空间大。
有鉴于此，本申请实施例提出一种射频电路，通过改变开关的端口连接实现天线共用，在一根天线上同时接收LTE信号和NR信号，进而减少天线数量，缩小天线占用的空间，降低终端设备的体积。
为了便于理解，示例的给出部分与本申请实施例相关概念的说明以供参考。
1、LTE信号：是指根据LTE系列通信协议而发送的信号。LTE信号包括但不限于：通过LTE物理下行链路共享信道(PDSCH)或LTE物理上行链路共享信道(PU-SCH)发送的LTE数据信号、通过LTE物理下行控制信道(PDCCH)或LTE增强PDCCH(enhanced PDCCH，ePDCCH)或LTE物理上行控制信道(PUCCH)发送的LTE控制信号、以及LTE参考信号(例如，信道状态信息参考信号(CSI-RS)、公共参考信号(CRS)、解调参考符号(demodulationreference symbols，DMRS)、主同步信号和辅同步信号等)，还有通过LTE物理广播信道(PBCH)、LTE无线资源控制(RRC)高层协议和/或LTE媒体接入控制(MAC)控制元素(CE)传送的LTE信号。

需要说明的是，NR控制信号指根据NR系列通信协议发送的任何控制信号。NR控制信号包括但不限于：RRC信号、MAC控制元素(CE)和下行控制信息(DCI)；通过PBCH和剩余最小系统信息(RMSI)传送的控制信号；还有任何其他小区特定的、组特定的和/或UE特定的控制信号。RMSI可以包括不在PBCH中发送的特定最小系 统信息。可以通过PDSCH来发送RMSI。可以由通过PDCCH中的公共搜索空间发送的DCI消息来识别发送RMSI的PDSCH资源。DCI消息可以由具有由公共RNTI例如系统信息RNTI(system information RNTI，SI-RNTI)进行CRC加扰。
3、天线：一种变换器。天线用于将射频信号转换为相应波长的电磁波并辐射至空中，和/或，用于接收电磁波并将其转换为相应的射频信号。可以理解的是，同一天线既可以发射射频信号，也可以接收射频信号。射频信号可以包括LTE信号和NR信号等。
4、射频收发器：用于输出射频信号以及对天线接收的射频信号进行信号处理。信号处理包括但不限于变频、解调和模数转换等。射频收发器可以包括：频分双工器(frequency-division duplex，FDD)、时分双工器(time-division duplex，TDD)、开关和/或合路器等。FDD和TDD均用于分离通路中发射信号和接收信号，降低发射信号和接收信号之间的干扰。开关和合路器均可以将一路信号分为两路信号，方便后续将不同的信号分开及处理。本申请实施例对射频信号的处理过程不做限定和说明。

开关用于将射频收发器201的第二端口201B一路接收的LTE信号和接收的NR信号分为两路，方便后续将接收的LTE信号和接收的NR信号分开及处理。开关和合路器的作用相同，可能实现的方式中，开关可以用合路器代替。

在NR通信中的天线配置可以参照上述ENDC通信中发射和/或接收NR信号时的天线配置，NR通信中的第九开关、第十开关、第十一开关和第十二开关的连接方式与上述ENDC通信中发射和/或接收NR信号时的连接方式类似，此处不再赘述。
综上，图30所示的射频电路中，终端设备通过5根天线，以及改变第九开关、第十开关、第十一开关和/或第十二开关的连接方式，实现LTE通信、SRS轮发和ENDC通信，实现SA和NSA的双模功能。天线数量减少，缩小天线占用的空间，降低终端设备的体积。终端设备还可以选择合适的天线发射LTE信号，改善吞吐率。并且在SRS轮发或NR通信时，不会影响LTE信号的发射。
