具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能组件划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的组件划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本申请提供了一种终端设备及其控制方法、计算机可读存储介质，通过信号检测组件能够对通过耦合器从天线获取到的干扰信号进行检测，从而获取到各个射频链路的干扰信号强度值，进而通过控制组件根据该干扰信号强度值确定射频链路的受干扰程度，即，能够了解到各个射频链路所受到干扰的程度影响，从而可根据此影响情况从全部射频链路中 选择出合适的射频链路作为主集接收通道，因此，能够提高终端设备在多通道工作模式下的抗干扰能力，改善终端设备的通信能力，进而提升终端设备的吞吐性能。
下面结合附图，对本申请实施例作进一步阐述。
如图1所示，图1是本申请一个实施例提供的终端设备的示意图。
在图1的示例中，该终端设备包括两个射频链路100，射频链路100包括天线110、耦合器120和被设置成检测干扰信号的功率强度的信号检测组件130，耦合器120设置有第一信号端IN、第二信号端OUT、第一耦合端CPL和第二耦合端TERM，信号检测组件130设置有信号输入端T1和信号输出端T2，第二信号端OUT与天线110连接，第二耦合端TERM与信号输入端T1连接；
控制组件200，分别与第一信号端IN、第一耦合端CPL和信号输出端T2连接，被设置成根据由信号检测组件130发送的干扰信号强度值确定射频链路100的受干扰程度，并且被设置成根据各个射频链路100的受干扰程度从两个射频链路100中选择作为主集接收通道的射频链路100，其中，干扰信号强度值由信号检测组件130对通过耦合器120从天线110获取到的干扰信号进行检测而得到。
应当说明的是，由于两个射频链路100的结构及工作方式等均是相同的，为免冗余，在图1中仅示出其中一个射频链路100的具体结构，相应地，另一射频链路100(即图1中所示的BLOCK与天线110所组合形成的结构)的具体结构也可由此得到。
在一实施例中，通过信号检测组件130能够对通过耦合器120从天线110获取到的干扰信号进行检测，从而获取到各个射频链路100的干扰信号强度值，由于射频链路100的干扰信号强度值与其受干扰程度相关，即，干扰信号强度值越大，射频链路100所受到的干扰程度越大，因此可以根据该干扰信号强度值确定射频链路100的受干扰程度，当确定各个射频链路100所受到干扰的程度影响后，可以根据此影响情况从全部射频链路100中选择出合适的射频链路100作为主集接收通道，因此能够提高终端设备在多通道工作模式下的抗干扰能力，改善终端设备的通信能力，进而提升终端设备的吞吐性能。
在一实施例中，“主集接收”与“分集接收”是本领域的两个技术术语，作为主集接收通道的射频链路100中的天线110，主要负责射频信号的发送和接收，相应地，作为分集接收通道的射频链路100中的天线110，一般只负责接收信号而不发送信号，最终基站会把从两个通道所收到的信号进行合并处理，可见，当根据各个射频链路100的受干扰程度所选出的射频链路100被确定为主集通道进行接收时，由于改善了该天线110所受到的干扰，因此其能够对信号执行完整的发送和接收流程，从而能够提高终端设备在多通道工作模式下的抗干扰能力，进而也能够使基站获得相应增益。
在一实施例中，终端设备可以但不限于是5G终端设备，也可以是与5G终端设备相关联的产品，比如5G网络外围设备、5G网络模组、5G网络芯片、5G网络数据平台、移动宽带产品或者物联网产品等，并且无论是5G终端设备还是与5G终端设备相关联的产品，均能够支持在非独立组网(Non-Standalone，NSA)或独立组网(Standalone，SA)模式下进行设置，也能够在所有支持探测参考信号(Sounding Reference Signal，SRS)的场景下进行设置；或者，终端设备也可以是无线网络下的客户前置设备(Customer Premise Equipment，CPE)，即为无线路由器设备。
在一实施例中，根据终端设备在实际中不同场景下的应用情况，射频链路100的数量 也可设置为大于两个的任意值，这在本实施例中并未限制。
在一实施例中，控制组件200，可以具体被设置成根据各个射频链路100的受干扰程度从两个射频链路100中确定受干扰程度最大的射频链路100，并从两个射频链路100中选择除受干扰程度最大的射频链路100之外的任意一条射频链路100作为主集接收通道的射频链路100。由于受干扰程度最大的射频链路100会显著影响到天线110的性能，因此可以确定其不适宜作为主集接收通道，进而从两个射频链路100中去除受干扰程度最大的射频链路100并从剩下的射频链路100中选取相应的射频链路100，则可以将受干扰较小的天线110所对应的射频链路100设置为主集接收通道，进而能够提高终端设备在多通道工作模式下的抗干扰能力，并且提升终端设备的吞吐性能。
在一实施例中，控制组件200，也可以具体被设置成根据各个射频链路100的受干扰程度从两个射频链路100中选择受干扰程度最小的射频链路100作为主集接收通道的射频链路100。受干扰程度最小的射频链路100所对应的天线110受干扰程度也最小，因此，该射频链路100适宜作为主集接收通道，能够提高终端设备在多通道工作模式下的抗干扰能力，进而提升终端设备的吞吐性能。
在一实施例中，耦合器120的型号与规格不受限制，可以根据实际情况进行选取，但无论如何，耦合器120可以切换到获取天线110信号的耦合模式，此时其信号流向依次经过：天线110、第二信号端OUT、第二耦合端TERM、信号输入端T1、信号输出端T2和控制组件200，在这一过程中，也存在部分信号通过第一耦合端CPL直接回到控制组件200的情况，但不影响对于天线110信号的检测；另外，耦合器120也可以切换到发射天线110信号的耦合模式，此时其信号流向依次经过：控制组件200、第一信号端IN、第二信号端OUT和天线110；可见，本实施例不仅可以用于获取天线110信号以对其进行检测，同时还可以耦合输出天线110信号，因此具有一定的多用性，可以提升移动终端的使用效果。
在一实施例中，终端设备还设置有链路开关，该链路开关设置有与控制组件200连接的链路开关输入端、分别与各射频链路100连接的链路开关输出端以及与控制组件200连接的链路控制端，当控制组件200根据各个射频链路100的受干扰程度从两个射频链路100中选择作为主集接收通道的射频链路100后，则只需通过控制链路控制端开启相应的链路开关输出端，即能够实现作为主集接收通道的射频链路100的导通切换，应当说明的是，在实际应用中，链路开关可以设置有多个，通过多个链路开关也能够实现将作为主集接收通道的射频链路100进行导通切换，其基本原理与上述实施例是相同的，为免冗余，在此不作赘述。
在一实施例中，终端设备还设置有功率放大器，该功率放大器与控制组件200连接，当所获取的天线110信号出现失真时，通过功率放大器能够将作为主集接收通道的射频链路100所对应的天线110信号进行功率放大，从而提升作为主集接收通道的射频链路100的通信效果，进而提升终端设备的吞吐性能。
在一实施例中，控制组件200设置有射频输入端和反馈输出端，其中，射频输入端连接于第一信号端，信号输出端连接于反馈输出端，通过射频输入端能够与耦合器之间实现信号传输，通过反馈输入端能够获取来自信号输出端的干扰信号强度值，可见，设置射频输入端和反馈输出端可以使得控制组件200能够更加稳定可靠地进行工作，有利于提升其工作稳定性。
如图2所示，图2是本申请另一个实施例提供的终端设备的示意图。
在图2的示例中，信号检测组件包括被设置成对通过耦合器120从天线110获取到的干扰信号进行滤波的滤波模块131和被设置成对经过滤波的干扰信号进行信号强度检测的检测模块132；滤波模块131设置有滤波输入端A1和滤波输出端A2，检测模块132设置有检测输入端B1和检测输出端B2，滤波输入端A1连接信号输入端T1，滤波输出端A2连接检测输入端B1，检测输出端B2连接信号输出端T2。
在一实施例中，滤波模块131通过滤波输入端A1获取到相应的干扰信号并能够对干扰信号进行滤波，进而通过滤波输出端A2输出滤波后的干扰信号，由于滤波后的干扰信号中的杂质成分基本被滤除，因此滤波后的干扰信号的性能会更加稳定，当检测模块132接收滤波后的干扰信号并对其进行检测，则能够稳定测出干扰信号强度值，即，能够准确可靠的了解天线110中的受干扰情况，以便于控制组件200能够准确地从两个射频链路100中选择作为主集接收通道的射频链路100。
在一实施例中，滤波模块131可以采用各种型号或规格的滤波器，检测模块132可以是被设置成对经过滤波后的干扰信号进行功率检波的相关电路，即，通过功率检波能够将经过滤波后的干扰信号进行数字化处理，从而获得与其对应的数字信号，通过数字信号则能够直接获取其信号强度，另外，检测模块132还可以包括放大电路，比如，在获得所述的数字信号之后，若经过转换的数字信号的增益、功率等出现失真，则检测模块132可以将数字信号进行放大再供给控制组件200，以便于控制组件200更容易识别放大后的数字信号并根据其确定射频链路100的受干扰程度。
如图3所示，图3是本申请另一个实施例提供的终端设备的示意图。
在图3的示例中，滤波模块131的数量为多个，并且各个滤波模块131具有不同的滤波频段；信号检测组件还包括第一开关140，第一开关140设置有第一开关输入端D1、第一开关输出端D2和第一控制端，第一开关输入端D1连接信号输入端T1，第一控制端连接控制组件200，第一开关输出端D2的数量和滤波模块131的数量相一致，第一开关输出端D2连接滤波输入端A1。
在一实施例中，控制组件200通过第一信号端IN或第一耦合端CPL可以获取到天线110中干扰信号的频段信息，并通过第一控制端将该信息反馈至与该信息对应的第一开关140，同时仅控制该第一开关140打开，则对应滤波频段的滤波模块131实现导通从而对干扰信号进行滤波输出，可见，第一开关140可以看作为具有多个开关端口的导通元件，通过此种控制方式可以仅控制相应滤波频段的滤波模块131打开，不会出现滤波模块131误打开的情况，即，不会对除干扰信号之外的其它信号进行无用过滤，能够保证输出稳定可靠的经过滤波的干扰信号。
在一实施例中，信号检测组件还包括第二开关150，第二开关150设置有第二开关输入端C1、第二开关输出端C2和第二控制端，第二开关输出端C2连接检测输入端B1，第二控制端连接控制组件200，第二开关输入端C1的数量和滤波模块131的数量相一致，第二开关输入端C1连接滤波输出端A2，其中，该第二开关150相对于第一开关140可以单独设置，也可以与第一开关140配合设置在滤波模块131两端，对于第二开关150所取得的技术效果而言是一致的，比如，在图3的示例中，除了设置有第一开关140，还设置有第二开关150，当对应滤波频段的滤波模块131实现导通从而对干扰信号进行滤波输出， 可以控制与该滤波模块131对应的第二开关输入端C1导通，从而将经过滤波后的干扰信号输出到检测模块132，通过此种控制方式可以仅控制经过滤波的干扰信号只会从其对应频段的滤波输出端A2所输出，不会出现经过滤波后的干扰信号误输出的情况，使得检测模块132能够稳定获取经过滤波的干扰信号。
在一实施例中，控制第一开关140打开及对应的滤波模块131实现滤波的时机可以设定为在天线110信号工作及传输过程中的特定间隔，比如5G中NR模式下的时隙，这样的检测方式对于天线110信号的工作及传输不会造成过大的影响，或者，本领域技术人员也可以根据实际情况自行设定相应时机以控制第一开关140打开及对应的滤波模块131实现滤波。
如图4所示，图4是本申请另一个实施例提供的终端设备的示意图。
在图4的示例中，射频链路100还包括第三开关160，第一耦合端CPL通过第三开关160连接控制组件200。
在一实施例中，第三开关160可以是单刀双掷开关，此时第三开关160设置有第三开关输入端和能够进行切换的第三开关输出端，第三开关输入端连接到第一耦合端CPL；当耦合器120处于发送天线信号的耦合模式下时，第三开关输出端连接控制组件200，起到辅助耦合作用，另一种情况下，当耦合器120处于接收天线信号的耦合模式下时，第三开关输出端被切换到通过负载连接到地，从而实现阻抗匹配，也可以防止从第二信号端所输入的天线信号中部分被第一耦合端CPL所接收，以免其影响干扰信号的检测精度。
在一实施例中，第三开关160还可以是各种型号的继电器，继电器设置有触点开关，该触点开关一端连接第一耦合端CPL，另一端可以在连接负载与连接控制组件200之间进行切换，也能够起到与上述实施例相同的作用，在此不作赘述。
在一实施例中，射频链路100还可以包括第四开关170，第二耦合端TERM通过第四开关170连接信号输入端T1，其中，该第四开关170相对于第三开关160可以单独设置，也可以与第三开关160配合设置在耦合器120两端，对于第四开关170所取得的技术效果而言是一致的，比如，在图4的示例中，除了设置有第三开关160，还设置有第四开关170，第三开关160也可以是单刀双掷开关或各种型号的继电器，当第四开关170为单刀双掷开关，此时第四开关170设置有第四开关输入端和能够进行切换的第四开关输出端，第四开关输入端连接到第二耦合端TERM；当耦合器120处于发送天线信号的耦合模式下时，此时不用于获取并检测天线信号，则第四开关输出端连接通过负载连接到地，从而实现阻抗匹配，也可以防止从第一信号端IN所输出的天线信号中部分被第二耦合端TERM所接收，以免其影响天线信号的发射强度，另一种情况下，当耦合器120处于接收天线信号的耦合模式下时，第四开关输出端被切换到连接信号输入端T1，起到辅助耦合作用，应当说明的是，第一耦合端CPL或第二耦合端TERM可以根据射频链路100的实际情况来各自适应性地调整阻抗匹配，这在本实施例中并未限制。
在一实施例中，通过设置第三开关160或/和第四开关170就能够辅助射频链路100进行工作，可见，本实施例中无需在射频链路100中添加额外的有源器件或/和无源器件进行辅助，这样既能够减少额外器件可能会带来的插损，同时也相对节省了射频链路100的材料成本。
参照图5，图5是本申请另一个实施例提供的终端设备300的示意图。
如图5所示，该终端设备300包括：一个或多个控制处理器和存储器，图6中以一个控制处理器及一个存储器为例。
控制处理器和存储器可以通过总线或者其他方式连接，图6中以通过总线连接为例。
存储器作为一种非暂态计算机可读存储介质，可用于存储非暂态软件程序以及非暂态性计算机可执行程序。此外，存储器可以包括高速随机存取存储器，还可以包括非暂态存储器，例如至少一个磁盘存储器件、闪存器件、或其他非暂态固态存储器件。在一些实施方式中，存储器可包括相对于控制处理器远程设置的远程存储器，这些远程存储器可以通过网络连接至该控制处理器。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
本申请实施例描述的终端设备300以及应用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，本领域技术人员可知，随着终端设备300的演变和新应用场景的出现，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。
本领域技术人员可以理解的是，图5中示出的终端设备300并不构成对本申请实施例的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
在图5所示的终端设备300中，可通过其存储器内部所存储的指令，由控制处理器基于该指令进行执行相应的终端设备300控制方法。
由于本实施例中的终端设备300与上述各实施例中的终端设备300属于同一发明构思，因此本实施例中的终端设备300的具体实施方式，可以参照上述各实施例中的终端设备300的具体实施例，为避免冗余，本实施例的终端设备300的具体实施方式在此不再赘述。
基于上述终端设备300的结构，提出本申请的终端设备300控制方法的各个实施例。
如图6所示，图6是本申请一个实施例提供的终端设备控制方法的流程图，该终端设备控制方法可以应用于如图1或图5所示的终端设备，该方法包括但不限于：
步骤S100,针对各个射频链路，获取由信号检测组件发送的干扰信号强度值，并根据干扰信号强度值确定当前射频链路的受干扰程度，其中，干扰信号强度值由信号检测组件对通过耦合器从天线获取到的干扰信号进行检测而得到；
步骤S200,根据各个射频链路的受干扰程度从至少两个射频链路中选择作为主集接收通道的射频链路。
在一实施例中，针对各个射频链路，通过信号检测组件能够对通过耦合器从天线获取到的干扰信号进行检测，从而获取到各个射频链路的干扰信号强度值，进而通过控制组件根据该干扰信号强度值确定射频链路的受干扰程度，即，能够了解到各个射频链路所受到干扰的程度影响，从而可根据此影响情况从全部射频链路中选择出合适的射频链路作为主集接收通道，因此，能够提高终端设备在多通道工作模式下的抗干扰能力，改善终端设备的通信能力，进而提升终端设备的吞吐性能。
值得注意的是，从至少两个射频链路中选择作为主集接收通道的射频链路之后，该终端设备仍然会依靠所有射频链路同时工作以实现通信，即，本实施例主要是通过减小作为主集接收通道的射频链路所受到的干扰以提高终端设备在多通道工作模式下的抗干扰能力，相比于相关技术中的采用算法使得互扰频段分时工作的方式，本实施例中的终端设备能够维持在多通道工作模式下进行工作，从而能够具有更强的通信传输能力和更高的吞吐 性能。
需要说明的是，由于本实施例中的终端设备控制方法与上述图1及图6实施例中的终端设备属于同一发明构思，因此本实施例中的终端设备控制方法的其它具体实施方式，可以参照上述实施例中的终端设备的具体实施例，为避免冗余，本实施例的终端设备控制方法的其它具体实施方式在此不再赘述。
如图7所示，步骤S200还包括但不限于：
步骤S210，根据各个射频链路的受干扰程度从至少两个射频链路中确定受干扰程度最大的射频链路，并从至少两个射频链路中选择除受干扰程度最大的射频链路之外的任意一条射频链路作为主集接收通道的射频链路。
在一实施例中，由于受干扰程度最大的射频链路会显著影响到天线的性能，因此可以确定其不适宜作为主集接收通道，进而从两个射频链路中去除受干扰程度最大的射频链路并从剩下的射频链路中选取相应的射频链路，则可以将受干扰较小的天线所对应的射频链路设置为主集接收通道，进而能够提高终端设备在多通道工作模式下的抗干扰能力，并且提升终端设备的吞吐性能。
如图8所示，步骤S200还包括但不限于：
步骤S220，根据各个射频链路的受干扰程度从至少两个射频链路中选择受干扰程度最小的射频链路作为主集接收通道的射频链路。
在一实施例中，受干扰程度最小的射频链路所对应的天线受干扰程度也最小，因此，该射频链路适宜作为主集接收通道，能够提高终端设备在多通道工作模式下的抗干扰能力，进而提升终端设备的吞吐性能。
如图9所示，在该终端设备控制方法还可以应用于如图2至图5中任一所示的终端设备的情况下，步骤S100还包括但不限于：
步骤S110，根据通过耦合器从天线获取到的干扰信号确定干扰信号所处频段；
步骤S120，根据干扰信号所处频段从多个滤波模块中确定与干扰信号匹配的目标滤波模块；
步骤S130，控制第一开关和第二开关选通目标滤波模块。
步骤S140，获取由检测模块发送的干扰信号强度值，干扰信号强度值由检测模块对经过目标滤波模块的干扰信号进行信号强度检测而得到。
在一实施例中，在确定干扰信号所处频段后，进而能够从多个滤波模块中确定与干扰信号匹配的目标滤波模块，从而能够对应控制第一开关和第二开关的相应端口打开，使得只有经过目标滤波模块的信号能够进行导通(包括输入信号及输出信号)，可以避免天线中其它信号对于干扰信号检测所带来的影响，从而使得针对干扰信号的检测精度大大提高。
此外，本申请的一个实施例还提供了一种计算机可读存储介质，该计算机可读存储介质存储有计算机可执行指令，该计算机可执行指令被一个处理器或控制器执行，例如，被上述节点实施例中的一个处理器执行，可使得上述处理器执行上述实施例中的终端设备控制方法，例如，执行以上描述的图6中的方法步骤S100至S200、图7中的方法步骤S210、图8中的方法步骤S220或图9中的方法步骤S110至S140。
本申请实施例包括：终端设备包括至少两个射频链路，射频链路包括天线、耦合器和被设置成检测干扰信号的功率强度的信号检测组件，耦合器设置有第一信号端、第二信号 端、第一耦合端和第二耦合端，信号检测组件设置有信号输入端和信号输出端，第二信号端与天线连接，第二耦合端与信号输入端连接；以及控制组件，分别与第一信号端、第一耦合端和信号输出端连接，被设置成根据由信号检测组件发送的干扰信号强度值确定射频链路的受干扰程度，并且被设置成根据各个射频链路的受干扰程度从至少两个射频链路中选择作为主集接收通道的射频链路，其中，干扰信号强度值由信号检测组件对通过耦合器从天线获取到的干扰信号进行检测而得到。本申请实施例中，通过信号检测组件能够对通过耦合器从天线获取到的干扰信号进行检测，从而获取到各个射频链路的干扰信号强度值，进而通过控制组件根据该干扰信号强度值确定射频链路的受干扰程度，即，能够了解到各个射频链路所受到干扰的程度影响，从而可根据此影响情况从全部射频链路中选择出合适的射频链路作为主集接收通道，因此，能够提高终端设备在多通道工作模式下的抗干扰能力，改善终端设备的通信能力，进而提升终端设备的吞吐性能。
