背景技术
在卫星通信场景中，无线电导航系统(radio navigation satellite system，RNSS)中的卫星可以播发无线电导航信号，终端设备在捕获到足够数量卫星播发的无线电导航信号后能够自主完成测距、定位。卫星无线电测定业务(radio determination satellite service，RDSS)是北斗卫星导航系统的独有服务功能，可以通过卫星信号提供双向短报文服务。例如：终端设备可以通过RDSS发射链路向卫星发送消息，卫星将接收到的消息转发至地面站，以及可以基于RDSS接收链路解析地面站通过卫星转发的消息。
对于终端设备来说RDSS和RNSS最大的区别在于RDSS有发射链路，并且由于发射的信号需要和卫星进行通信，因此对发射功率有较高的要求。目前，一种实现是通过有源收发天线完成对RDSS信号的发送，以使发送的信号达到发射功率要求。然而，有源天线需要额外的电源模块和信号放大模块，对于体积较小的手机等终端设备显然并不适用。

具体实施方式
图1为本申请实施例提供的一种可能的应用场景示意图。该应用场景中包括卫星、地面站和终端设备。在该应用场景中，终端设备可以发送上行信号至卫星，卫星转发该上行信号到地面站，地面站可以发送下行信号到卫星，卫星再将该下行信号转发至终端设备。示例性的，在该应用场景中，卫星定位系统和卫星通信系统可以同时存在，卫星可以播发卫星定位系统的信号(如无线电导航信号)，终端设备可以基于卫星定位系统的信号完成测距、定位。终端设备也可以基于卫星完成卫星通信系统的信号的发送和接收，与卫星地面站进行通信。需要说明的是，本申请实施例中不限定图1所示应用场景中卫星、地面站和终端设备的个数。
可选的，卫星定位系统可以但不限于为卫星无线电导航系统(radio navigation satellite system，RNSS)，RNSS可以播发卫星无线电导航信号，终端设备在捕捉到足够的卫星数后可以自主完成测距、定位。卫星通信系统可以但不限于为卫星无线电测定系统(radio determination satellite system，RDSS)，RDSS是北斗卫星导航系统的服务功能，可以提供双向短报文信息服务(即卫星通信功能)。
RNSS基本工作过程可以参照图2所示：终端设备可以通过RNSS接收链路接收来自多个卫星的无线电导航信号完成定位(如基于接收的来自多个卫星的无线电导航信号，确定多个卫星的位置和终端设备分别与多个卫星的距离，从而确定终端设备的位置)。RDSS基本工作过程可以参照图3所示：用户需要通信服务时，利用终端设备的RDSS发射链路通过上行链路发送信号至卫星，卫星通过下行链路转发至地面站。地面站接收卫星信号，处理用户信息后通过上行链路发送至卫星。然后卫星通过下行链路向终端设备转发通信信息，终端设备通过RDSS接收链路接收通信信息。
上述终端设备，又可以称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。例如，终端设备可以包括具有无线连接功能的手持式设备、车载设备等。目前，终端设备可以是：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备、消费终端(如手表、手环等)、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)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，或智慧家庭(smart home)中的无线终端等。
参照图4所示，为RDSS发射(transport，TX)链路示意图，包括天线、RDSS TX射频(radio frequency，RF)前端、RDSS TX载波调制模块、RDSS TX滤波/数字数据转换器(digital data converter，DDC)模块、RDSS TX扩频模块和RDSS信道编码模块。
其中，上述RDSS TX载波调制模块、RDSS TX滤波/数字数据转换器(digital data converter，DDC)模块、RDSS TX扩频模块和RDSS信道编码模块可以构成RDSS基带信号处理单元。
RDSS信道编码模块，可用于对待发送的信息进行信道编码，即对用户编辑的待发送报文所对应的原始信息比特(bit)流进行信道编码，以确保接收端通过对应信道译码获得预设的信道编码增益。
RDSS TX扩频模块，可用于对信道编码后得到的符号数据进行扩频调制处理。
RDSS TX滤波/DDC等模块，可用于对调制好的信号频谱进行整形滤波，消除码间干扰，并进行频点搬移，将信号频谱的中心频点搬移到指定的发射频段上。
RDSS TX载波调制模块：对完成滤波的信号进行载波调制，将信号调制到某个中频上。
RDSS TX RF前端，也可以称为RDSS发射通路，可用于针对完成中频载波调制的信号进行数模转换(digital analog converte，DAC)得到模拟信号，并依赖射频前端电路对该模拟信号上变频至发射频率，经过功率放大器(power amplifier，PA)，放大至预定功率强度后通过天线完成信号的发射。
对于终端设备来说RDSS和RNSS最大的区别在于RDSS有发射链路，并且由于发射的信号需要和卫星进行通信，因此对发射功率有较高的要求，通常要求终端设备发射信号的等效全向辐射功率(equivalent isotropically radiated power，EIRP)值应不小于3.5分贝瓦(dBW)且不大于19dBW。对于手机等终端设备来说，即使是最低的3.5dBW EIRP值也需要很强的PA才能达到，因此如何提高发射信号的功率对手机等终端设备来说是非常重要的诉求。而采用有源天线需要额外的电源模块和信号放大模块，对于体积较小的手机等终端设备显然也并不适用。
鉴于此，本申请实施例提供了一种收发装置及终端设备，用以提升终端设备卫星通信信号的发射功率，降低终端设备对功放(如PA)等硬件的需求，从而减少终端设备的设计难度。
另外，需要理解的是，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第一天线和第二天线，并不是表示这两个天线对应的优先级或者重要程度等的不同。
本申请实施例中，对于名词的数目，除非特别说明，表示“单数名词或复数名词”，即"一个或多个”。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，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：单独存在A，同时存在A和B，单独存在B的情况，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。例如，A/B，表示：A或B。“以下至少一项(个)”或其类似表达，是指的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)，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。
如图5所示，为本申请实施例提供的一种收发装置示意图，该装置包括N个第一卫星通信系统发射通路、N个第一卫星定位系统接收通路和N个第一天线，N个第一天线分别与N个第一卫星通信系统发射通路和N个第一卫星定位系统接收通路一一连接，N为大于或等于1的整数；N个第一天线中的每个第一天线，用于发送连接的第一卫星通信系统发射通路的信号，或用于将来自卫星定位系统的信号发送至连接的第一卫星定位系统接收通路。这样第一卫星通信系统发射通路和第一卫星定位系统接收通路可以共用天线，可以减少收发装置中天线的数量，从而减少收发装置的体积，降低收发装置的系统集成成本。
在一些实施中，卫星通信系统发射通路可以为RDSS发射通路，卫星定位系统接收通路可以为RNSS接收通路，也即第一卫星通信系统发射通路为第一RDSS发射通路，第一卫星定位系统接收通路为第一RNSS接收通路。在以下的描述中，为方便描述，仅以卫星通信系统发射通路为RDSS发射通路，卫星定位系统接收通路为RNSS接收通路为例进行说明。
RDSS发射通路可以包括以下至少一项：数模转换器、滤波器、混频器、本地振荡器、增益控制器、功率放大器。RDSS发射通路可以实现对RDSS信号的以下中至少一项处理：数模转换、滤波、变频、功率增益控制、功率放大等处理。
RNSS接收通路可以包括以下至少一项：滤波器、低噪音放大器、混频器、本地振荡器、可变增益放大器、模数转换器。RNSS接收通路可以实现对RNSS信号的以下中至少一项处理：滤波、信号放大、变频、模数转换等处理。
其中，数模转换器可以通过数字模拟转换器(digital-to-analog converter，DAC)实现，该DAC完成数字信号到模拟信号的转换。
模数转换器可以通过模拟数字转换器(analog-to-digital converter，ADC)实现，该ADC完成模拟信号到数字信号的转换。
滤波器可以通过低通滤波器(low pass filter，LPF)、声表面波滤波器(surface acoustic wave，SAW)等实现，用于完成信号的滤波，以抑制非必要信号(如干扰信号)对链路的影响，提升通路性能，滤波器可复用。
混频器可以通过MIXER实现，该MIXER可以用于和本地振荡器(local oscillator，LO)一起更改信号频率。比如：可以用于完成RDSS发射通路的上变频，或者用于完成RNSS接收通路的下变频。
增益控制器可以通过脉冲功率放大器(pulse power amplifier，PPA)实现，该PPA可用于控制发射链路的输出信号功率。
功率放大器可以通过PA实现，该PA可用于实现发射通路的射频信号放大。
可变增益放大器可以通过可变增益放大器(variable-gain amplifier，VGA)实现，VGC可以用于对输入信号的自动增益控制。
低噪音放大器可以通过低噪音放大器(low noise amplifier，LNA)实现，LNA可以用于放大RNSS接收信号，降低噪声干扰。其中，在芯片上设置的LNA可以称为了内部LNA(internal LNA，iLNA)。
应理解，上述器件的实现方式仅为示例，还可以通过其他具体器件实现，本申请不再一一列举。
在一种可能的实施中，该收发装置还可以包括N个第一开关，N个第一天线分别通过N个第一开关与N个第一卫星通信系统发射通路和N个第一卫星定位系统接收通路一一连接，其中第一开关可以为单刀双掷开关。
以第一RDSS发射通路包括DAC、LPF、MIXER、LO、PPA、PA，第一RNSS接收通路包括SAW、LNA、iLNA、MIXER、LO、LPF、VGA、ADC，收发装置包括2(N＝2)个第一天线、2个第一开关、2个第一RDSS发射通路和2个第一RNSS接收通路为例进行说明，收发装置可以如图6所示。其中，每个第一开关可以包括第一端、第二端和第三端，第一端与第一天线连接，第二端与第一RDSS发射通路连接，第三端与第一RNSS接收通路连接；当第一端和第二端连接时，第一天线与第一RDSS发射通路连接；当第一端和第三端连接时，第一天线与第一RNSS接收通路连接。也就是说，第一RDSS发射通路和第一RNSS接收通路可以通过第一开关共用第一天线。以第一天线1通过第一开关1分别与第一RDSS发射通路1和第一RNSS接收通路1连接为例，第一开关1与第一天线1连接的端可以理解为第一端，与第一RDSS发射通路1连接的端可以理解为第二端，与第一RNSS接收通路1连接的端可以理解为第三端。
另外，因为RDSS的接收频点和发射频点分别为2.4GHz和1.6GHz，而RNSS的L1频段天线、L2频段天线和L5频段天线所对应的频段分别为1.559-1.610GHz、1.215-1.300GHz、1.164-1.215GHz，与RDSS的发射频点相近，因此在本申请实施例中，可以复用第一RNSS接收通路的天线完成RDSS信号的发射，也即在N小于或等于3时，N个第一天线为RNSS的L1频段天线、L2频段天线和L5频段天线中的N个。作为一种示例，如图6所示，在N为2时，2个第一天线可以分别为RNSS的L1频段天线和L5频段天线。
可以理解的，为了进一步提高收发装置的集成度，减少收发装置的体积，如图7所示，N个第一RDSS发射通路可以连接同一RDSS基带信号处理单元，N个第一RDSS发射通路由同一RDSS基带信 号处理单元提供信号。类似的，N个第一RNSS接收通路可以连接同一RNSS基带信号处理单元，由RNSS基带信号处理单元对N个第一RNSS接收通路接收到的RNSS信号进行处理。其中，RNSS基带处理单元主要负责L1/L5频点RNSS基带信号的处理，在RNSS基带处理单元中可以包括数字前端(digital front-end(，DFE)、捕获模块(acquisition module，ACQ)、跟踪模块(tracking module，TRK)等子模块。RDSS基带处理单元主要负责多天线RDSS基带信号的处理，包含接收和发射两部分，其中接收处理流程和RNSS基带处理单元类似但增加了多天线并行处理，发射包含多路RDSS信号组装、整形滤波、插值滤波等流程。
在一些实施例中，为了保证多个第一RDSS发射通路发射信号的同步性，如图7所示，N个第一RDSS发射通路可以连接同一LO，由同一LO为多个N个第一RDSS发射通路提供时钟信号。另外，为了进一步提高收发装置的集成度，LO还可以与N个第一RNSS接收通路连接，并可以通过分频的形式分别向N个第一RDSS发射通路和N个第一RNSS接收通路提供时钟信号。
需要理解的是，上述LO也可以替换为锁相环(phase locking loop，PLL)，由PLL向通过分频的形式分别向N个第一RDSS发射通路和N个第一RNSS接收通路提供时钟信号(也可以称为LO信号)。
在一些实施中，为了避免RDSS信号发射期间，因为第一RNSS接收通路的天线被第一RDSS发射通路使用，无法接收RNSS信号，收发装置还可以包括不与RDSS发射通路共用天线的RNSS接收通路，如包括O个第二RNSS接收通路，O为大于或等于0的整数。如图8所示的收发装置，在图7所示的收发装置的基础上收发装置还包括1个(O＝1)不与RDSS发射通路共用天线的第二RNSS接收通路和第三天线。采用图8所示的收发装置能够支持RNSS接收通路(如第二RNSS接收通路1)和RDSS发射通路(如第一RDSS发射通路1和第一RDSS发射通路2)同时工作，在RDSS发射通路工作期间，RNSS接收通路也能正常接收RNSS信号以确保不失定位。
另外，为了进一步降低对PA的需求，增加RDSS信号的发射强度，该收发装置还可以包括M个第二RDSS发射通路和M个第二天线，M个第二天线与所述M个第二RDSS发射通路一一连接，M为大于或等于1的整数。M个第二天线中的每个第二天线，用于发送连接的第二RDSS发射通路的信号。
以M等于1为例，作为一种示例：收发装置可以如图9所示，包括共用第一天线(L1频段天线)的第一RDSS发射通路1和第一RNSS接收通路1，以及单独与第二天线1(如另一个L1频段天线)连接的第二RDSS发射通路1、单独与第三天线1(L5频段天线)连接的第二RNSS接收通路2。
另外，为了保证多个第一RDSS发射通路发射信号的同步性，如图9和图10所示，N(图9和图10中以N为1为例)个第一RDSS发射通路和M(图9和图10中以M为1为例)个第二RDSS发射通路可以连接同一LO，由同一LO为N个第一RDSS发射通路和M个第二发射通路提供时钟信号。
此外，为了进一步提高收发装置的集成度，如图10所示，N个第一RNSS接收通路和O(图10中以O为1为例)个第二RNSS接收通路，还可以与N个第一RDSS发射通路和M个第二RDSS发射通路共用同一LO，LO可以通过分频的形式分别向N个第一RDSS发射通路+M个第二RDSS发射通路，以及N个第一RNSS接收通路+O个第二RNSS接收通路提供时钟信号。
参照如图11所示的RDSS信号发射示意图，在本申请实施例中，n(n为N或者N+M)个RDSS发射通路所连接的n个天线，可以通过波束成型等技术向特定卫星(如卫星1)发射RDSS信号(即RDSS的信号)，能够增加RDSS信号发射增益，相对于现有单个RDSS发射通路的发射方式，能够进一步降低RDSS发射通路对PA的需求，达到RDSS信号发射所需的EIRP值。在图11所示的RDSS TX链路包括双RDSS发射通路双天线的情况下，相对于如图4所示的RDSS TX链路，可稳定提升信号灵敏度2-3db。
基于同一技术构思，如图12所示，本申请实施例还提供一种终端设备1200，包括处理器1210，以及如图5-9任一附图所示的收发装置1220，处理器1210和收发装置1220之间相互耦合。收发装置1220可用于接收来自该终端设备之外的其它设备(如卫星、基站等)的信号并传输至处理器1210或将来自处理器1210的信号发送给该终端设备之外的其它设备。
可选的，终端设备1200还可以包括存储器1230，用于存储处理器1210执行的指令或存储处理器1210运行指令所需要的输入数据或存储处理器1210运行指令后产生的数据。存储器1230可以是物理上独立的单元，也可以与处理器1210耦合，或者处理器1210包括该存储器1230。
本申请实施例中不限定上述处理器1210、收发装置1220以及存储器1230之间的具体连接介质。本申请实施例在图12中以处理器1210、收发装置1220以及存储器1230之间通过总线连接为例，总线 在图12中以粗线表示，其连接方式，仅是进行示意性说明，并不引以为限。总线可以分为地址总线、数据总线、控制总线等。为便于表示，图12中仅用一条粗线表示，但并不表示仅有一根总线或一种类型的总线。
在本申请中，应该理解到，所揭露的设备，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元或单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性或其它的形式。
在本申请实施例中的各功能单元可以集成在一个处理单元中，或者各个单元也可以均是独立的物理模块。
所述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本申请的技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备，例如可以是个人计算机，服务器，或者网络设备等，或处理器(processor)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：通用串行总线闪存盘(universal serial bus flash drive)、移动硬盘、只读存储器(read-only memory，ROM)、随机存取存储器(random access memory，RAM)、磁碟或者光盘等各种可以存储程序代码的介质。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请实施例进行各种改动和变型而不脱离本申请实施例的精神和范围。这样，倘若本申请实施例的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
