以下结合图1介绍本申请实施例提供的射频装置的控制方法。
如图1所示，该射频装置的控制方法包括以下步骤101和步骤102。
步骤101，在第一发射电路工作且第二发射电路空闲的情况下，获取所述第一发射电路和所述第二发射电路各自的温度信息。
其中，所述第一发射电路和所述第二发射电路分别用于支持两种网络的射频信号的发射处理。
本申请中的射频装置支持双连接模式，其中，双连接模式可以包括演进型通用移动通信系统陆地无线接入网EUTRA新无线电NR-双连接Dual Connectivity(EN-DC)模式，或NR EUTRA-Dual Connectivity(NE-DC)模式，或下一代Next Generation EN-DC(NGEN-DC)模式等。因此该射频装置的硬件可以包括分别支持两种网络(如LTE网络和NR网络)的发射通路，即包括第一发射电路、第二发射电路这两个发射电路。当射频装置处于双连接模式时，可以 分别通过这两个发射电路对两种不同网络的射频信号进行发射处理。当射频装置处于单连接模式时，射频装置可能对NR网络的射频信号进行发射处理，也可能对LTE网络的射频信号进行发射处理。其中，上述两种不同网络的射频信号可以都为高频信号、都为中频信号、或者都为低频信号。上述两个发射电路与上述两种不同网络的射频信号具有对应关系，该对应关系是由驱动配置的，因此，基于与射频装置建立通信连接的基站类型(NR基站或LTE基站)，射频装置中的第一发射电路工作或第二发射电路工作，而两个发射电路中的另一个发射电路处于空闲状态。当射频装置长时间处于单连接模式时，一个发射电路可能因持续工作而温度上升，影响器件性能，导致器件的发射指标如邻道泄漏抑制比(Adjacent Channel Leakage Power Ratio,ACLR)、误差矢量幅度(Error Vector Magnitude,EVM)等变差。因此可以通过执行步骤101和步骤102来解决这个问题。
在本申请实施例中，在第一发射电路工作且第二发射电路空闲的情况下，可以获取这两个发射电路各自的温度信息，后续基于该温度信息来确定是否执行步骤102。具体的，第一发射电路可以包括第一功率放大器(Power amplifier,PA)模组和第一电源，第二发射电路可也包括第二功率放大器模组和第二电源，其中，第一PA模组、第二PA模组分别用于对第一网络(如NR网络)的射频信号、第二网络(如LTE网络)的射频信号进行功率放大处理，第一电源、第二电源分别用于为第一PA模组、第二PA模组提供电源。可理解的，第一PA模组、第二PA模组可以为多频多模功率放大器(Multi band multi mode power amplifier，MMPA)、集成双工器的功率放大器模组(Power amplifier module integrated duplexer，PAMid)，也可以为内置低噪声放大器的PAMid(即LPAMid)，第一电源、第二电源可以为直流变直流(DirectCurrent/DirectCurrent，DC/DC)电源，也可以为其他类型电源，本申请不作限制。可理解的，由于第一发射电路工作时，第一PA模组和第一电源均可能因为持续工作而温度上升，因此可以通过获取第一PA模组和第一电源的温度来获得第一发射电路的温度信息。也就是说，获取第一发射电路的温度信息可以包括：获取第一PA模组的第一温度和第一电源的第二温度。相应的，获取第二发射电路的温度信息可以包括：获取第二PA模组的第三温度和第二电源的第四温度。这样，可以监控发射电路中包括的多个电子器件的温度状态，来确定该发射电路中工作的电子器件是否发热严重，对射频装置的通信性能产生较大影响。对功率放大器模组、为功率放大器模组提供电能的电源均进行温度监控，有利于增加获得的温度信息的可靠性，并且可根据多个温度灵活调整后续步骤102中的温度差条件，提高发射电路的切换策略的实用性和灵活度。
在一种实施例中，可以通过温度检测模块来获得上述第一温度至第四温度。该温度检测模块可以包括热敏电阻，具体的，上述第一PA模组、第一电源、第二PA模组和第二电源附近可以均放置一个热敏电阻，每个热敏电阻处于分压电路中，通过获得该热敏电阻两端的电压，可以获得上述第一温度至第四温度。
在一种可能的实施例中，上述射频装置中的第一发射电路和第二发射电路在射频装置中的放置位置满足距离条件，即两个发射电路之间的距离大于距离阈值。在这种情况下，当一个发射电路工作时，若该发射电路因持续工作而温度上升，散发热量时，不会导致另一个发射电路也受影响发热，也就是说，第一发射电路和第二发射电路在布局上具有一定距离，不在同一个受热区域。这样，可以保证第一发射电路和第二发射电路的温度信息能满足下述步骤102中的温度差条件，从而实现利用空闲且温度较低的第二发射电路来代替温度较高的第二发射电路工作，缓解射频装置的发热问题，降低器件发射性能的恶化程度。
在本申请实施例中，由于第一发射电路工作而第二发射电路空闲，因此可确定射频装置 工作于单连接模式，且用于发射第一网络的射频信号。该射频电路中还包括两个天线和开关，其中，两个发射电路与两个天线分别对应，开关用于选择导通发射通路与天线之间的通路。当射频装置工作于双连接模式时，第一发射电路与第一天线之间的通路被导通，第二发射电路与第二天线之间的通路也被导通。在本申请中，射频装置工作于单连接模式且第一发射电路工作，因此开关可以用于选择导通第一发射电路与第一天线之间的通路，也就是说，第一网络的射频信号经第一发射电路中的第一PA模组进行功率放大后，可通过第一天线发射出去。
步骤102，在所述第一发射电路与所述第二发射电路的温度信息满足温度差条件的情况下，控制所述第二发射电路代替所述第一发射电路工作。
在一种可能的实施例中，上述温度差条件可以包括：上述第一PA模组的第一温度与上述第二PA模组的第三温度之间的温度差大于第一阈值，或者，上述第一电源的第二温度与上述第二电源的第四温度之间的温度差大于第二阈值。该第一阈值和第二阈值可以根据经验值设定，可以为固定的值，也可以根据射频装置的表面温度进行调整，例如当射频装置(或包括该射频装置的电子设备)的表面温度较高时，第一阈值(和第二阈值)设为稍大的值，当该表面温度特别高时，降低第一阈值(和第二阈值)。
在一种实施例中，由于第一发射电路工作时，开关导通第一PA模组和第一天线之间的通路，因此，当控制第二发射电路代替第一发射电路工作时，开关可以导通第二PA模组和第一天线之间的通路。因为不同天线(即上述第一天线和第二天线)所处位置的空间信道质量不一样，在固定使用场景空间信道质量不发生变化的情况下，让第二发射电路对第一网络的射频信号进行功率放大处理后依然通过第一天线发射出去，可以使得发射出去的信号质量不产生较大变化。这样，在第二天线所处位置的空间信道质量比第一天线所处位置的空间信道质量差时，可以避免因切换发射电路导致射频装置的发射性能进一步恶化。可选的，若确定第二天线所处位置的空间信道质量比第一天线所处位置的空间信道质量好，也可以控制开关导通第二PA模组与第二天线之间的通路，以实现第二发射电路代替第一发射电路工作。
可理解的，当第一发射电路因持续工作而温度上升，第二发射电路空闲且温度较低，且两个发射电路的温度信息满足温度差条件时，通过控制第二发射电路代替第一发射电路工作，可以使得第二发射电路正常工作来保证射频装置对第一网络的射频信号的正常发射处理，且第一发射电路可以加快散热使温度降低，因而可缓解第一发射电路持续工作导致的局部发热现象，避免射频装置的发射性能的进一步恶化，提高通信质量。
进一步的，若上述第二发射电路持续工作后温度上升，第一发射电路散热后温度下降，第二发射电路与第一发射电路的温度信息再次满足上述温度差条件，那么，可以控制第一发射电路代替第二发射电路工作。可理解的，当射频装置持续处于该单连接模式时，可能出现第一发射电路和第二发射电路的温度信息多次满足上述温度差条件的情况，因而第一发射电路和第二发射电路可以来回交替工作，以实现改善因单一发射电路持续工作温度升高导致的发射性能变差的情况，均衡射频装置的发热区域，提高通信质量和用户体验。
在一种可能的实施例中，上述第一发射电路工作而第二发射电路空闲时，上述开关可选择导通第一发射电路与第一天线之间的通路；当第一发射电路和第二发射电路的温度信息满足温度差条件，上述第二发射电路代替第一发射电路工作，上述开关选择导通第二发射电路与第一天线之间的通路。为了保证第二发射电路通过第一天线发射的射频信号与第一发射电路通过第一天线发射的射频信号的质量尽量接近，在本申请中，第二发射电路到第一天线的路径损耗与第一发射电路到第一天线的路径损耗应满足损耗条件，示例性的，该损耗条件可 以包括：上述两个路径损耗的差值小于预设阈值，该预设阈值可以根据实际发射电路中的器件参数和/或上行通信场景的通信质量要求等确定，本申请不作限制。可理解的，上述第一发射电路、第二发射电路、第一天线不特指射频装置中的具体器件，而只是用于区分不同的概念。因此，若射频装置中包括发射电路A、发射电路B、天线1、天线2，那么在本实施例中，发射电路A和发射电路B分别到天线1的路径损耗满足损耗条件，发射电路A和发射电路B分别到天线2的路径损耗也满足损耗条件。这样，可以在射频装置处于单连接模式且单一发射电路持续工作发热严重时，采取本申请提供的方法来使得另一空闲的发射电路代替发热严重的发射电路工作，以实现缓解局部发热的同时，保证发射的信号质量不因发射电路的切换而发生较大改变。
具体的，上述第一发射电路到第一天线的路径损耗与第二发射电路到第一天线的路径损耗满足损耗条件，可以是指上述第一PA模组到第一天线的端口的路径损耗，与上述第二PA模组到第一天线的端口的路径损耗满足损耗条件。也就是说，两个发射电路中各自的功率放大器模组到同一天线的同一端口的路径损耗相差不大。
本申请实施例中，在射频装置包括的第一发射电路持续工作而第二发射电路空闲时，持续监控这两个发射电路的温度信息，以确定是否出现单一发射电路发热严重的情况。当两个发射电路的温度信息满足温度差条件时，控制第二发射电路代替第一发射电路工作，即通过两个发射电路的温度差确定第一发射电路发热严重，则将工作的发射电路从第一发射电路切换为第二发射电路工作，这样，可以利用第二发射电路来保证射频信号的正常发射，且使第一发射电路通过散热降低温度，改善因发射通路温度上升导致的器件发射性能恶化的情况，缓解射频装置的局部发热问题，提高上行通信质量和通信性能，提高用户体验。
应该理解的是，虽然图1的流程图中的各个步骤按照箭头的指示依次显示但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，其可以以其他的顺序执行。而且，该图中的至少部分步骤可以包括多个子步骤或者多个阶段,这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，其执行顺序也不必然是依次进行，而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
以下将结合具体的应用场景介绍本申请实施例提供的射频装置的控制方法。
在该应用场景下，本申请提供的射频装置的结构示意图如图2所示，该射频装置包括的上述第一发射电路、第二发射电路可以分别是图2中的发射电路1、发射电路2。其中，每个发射电路均包括各自的功率放大器模组和电源，也即上述第一PA模组、第一电源、第二PA模组、第二电源可以分别是图2中的PAMiD1、DC/DC1、PAMiD2、DC/DC2。上述温度检测模块可以包括图2中的四个热敏电阻NTC1_0、NTC1_1、NTC2_0、NTC2_1，这些热敏电阻可分别用于检测PAMiD1、DC/DC1、PAMiD2、DC/DC2的温度。射频装置还可以包括开关SWITCH和两个天线ANT1、ANT2。该射频装置还可以包括射频芯片RF IC，用于将基带信号进行调制，得到射频信号后传输给第一发射电路和/或第二发射电路进行处理。可理解的，该射频装置还可以包括滤波器等电子器件，本申请中未在图2中示出。图2所示的射频装置可以工作于双连接模式，也可以工作于单连接模式。而执行本申请提供的射频装置的控制方法时，射频装置工作于单连接模式，如图3所示，此时上述方法包括以下步骤：
步骤301，射频装置中的发射电路1工作而发射电路2空闲。
其中，如图4所示，开关SWITCH选择导通发射电路1包括的PAMiD1与天线ANT1之 间的通路1(如图4中实线所示)，而发射电路2包括的PAMiD2与天线ANT2之间的通路2(如图4中虚线所示)未被导通。
步骤302，发射电路1工作使得温度上升，获取发射电路1和发射电路2的温度信息。
其中，发射电路1的温度信息包括PAMiD1、DC/DC1的温度，发射电路2的温度信息包括PAMiD2、DC/DC2的温度。
步骤303，判断发射电路1和发射电路2的温度信息是否满足温度差条件。若否，返回步骤301，若是，执行步骤304。
具体的，可以基于PAMiD1与PAMiD2的温度得到温度差X，基于DC/DC1与DC/DC2的温度得到温度差Y，当X>a或者Y>b时，确定满足温度差条件，其中，X和Y均为绝对值，a和b分别为上述第一阈值、第二阈值，可根据需要设定。
步骤304，控制发射电路2工作，发射电路1空闲。
此时，如图5所示，开关SWITCH选择导通发射电路2包括的PAMiD2与天线ANT1之间的通路3(如图5中实线所示)。
步骤305，发射电路2工作使得温度上升，获取发射电路1和发射电路2的温度信息。
其中，可以持续监测获得PAMiD1、DC/DC1、PAMiD2、DC/DC2的温度，来获得发射电路1和发射电路2的温度信息。
步骤306，判断发射电路1和发射电路2的温度信息是否满足温度差条件。若否，返回步骤304，若是，返回步骤301。
此时，可以继续获得PAMiD1与PAMiD2的温度差X，DC/DC1与DC/DC2的温度Y，并判断是否满足：X>a或者Y>b。根据判断结果确定后续执行步骤。若满足判断条件，则说明此时又出现单一发射电路发热且满足温度差条件的情况，需要再次进行发射电路的切换，缓解发热。
这样，在射频装置持续处于单连接模式且与上述第一网络(如NR网络或LTE网络)的基站进行通信的情况下，射频装置中的两个发射电路可以来回交替工作，以使得射频装置中的发射电路不会因工作导致温度上升超出限制，从而改善原有的单一发射电路工作导致器件发射性能恶化的情况，缓解射频装置的局部发热问题，提高上行通信质量，提高用户体验。
