然而，在5G或更高端的通信网络中，为了提高信号的处理效率，其上行信号对应的上行(Upload，UL)调制方式通常采用正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)，通过正交频分复用技术生成的上行信号的峰均比较高，其上行信号的峰均比可以高达8dB～12dB，该上行信号的峰均比较4G网络中的上行信号的峰均比提高至少3dB。而且，在5G或更高端的通信网络中，为了满足覆盖范围，终端设备的功率放大器的最大发射功率必须相应的提高，这样，终端设备的耗电自然会大大增加，待机时长会明显下降；同时，为了保持发射信号质量，终端设备的功率放大器必须在功率回退的状态下工作，而功率回退又会带来效率的降低，因此，在确保信号质量的前提下，需要尽可能高的提高功率放大器的效率，而如何提高终端设备的发射效率，同时控制终端设备的功耗，成为无线通信网络的关键技术。

为了使本技术领域的人员更好地理解本申请中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
实施例一
在5G网络中，毫米波(Millimeter Wave)将会成为重要的通信频段，毫米波频段具有大量可用频谱资源，能够满足移动通信日益增长的业务流量需求。此外，由于毫米波的波长较短，根据天线理论，毫米波系统的天线尺寸也可以较小，这样，可以使得能够在小范围空间中放置多根天线，有利于大规模天线阵列系统(Massive MIMO)在现实系统中的应用。虽然毫米波系统存在信道路径衰落过大的缺点，但可以利用大规模天线所提供的波束赋形技术(Beam Forming)来弥补毫米波信道路径衰落过大的缺点，从而为毫米波技术应用于移动通信提供了可能。波束赋形技术可以改善天线的方向性，从而获得更明显的阵列增益。因此，波束赋形技术在扩大覆盖范围、改善边缘吞吐量以及干扰抑止等方面都有很大的优势。基于上述内容，对于终端设备的射频前端，可以结合天线系统的波束赋形的技术特点(即方向性好、天线阵列的阵列增益高)，在完成和基站握手通信的情况下，通过提高天线阵列的阵列增益，从而降低终端设备的发射功率，达到节电的目的。本申请实施例提供一种基于毫米波通信的射频系统，如图1所示，该射频系统包括陶赫蒂Doherty功放单元100、天线阵列单元200和微控制单元MCU300，其中：
如图2所示，Doherty功放单元100可以是通过将2路功率放大器组成 Doherty结构的功率放大单元，Doherty功放单元100中可以包括一个主放大器103和一个峰值放大器104(或辅放大器)。功率放大器可以包括多个不同的类别，如A类放大器、B类放大器和AB类放大器等，其中的A类放大器是一种完全的线性放大形式的放大器，在A类放大器工作时，晶体管的正负通道不论有或没有信号都处于常开状态，其失真率极低。B类放大器为线性放大器，B类放大器在工作时，晶体管的正负通道通常处于关闭状态，除非有信号输入时晶体管的正负通道才会打开，即在正相信号输入时只有正相通道工作，负相通道关闭，两个通道不会同时工作，因此在没有信号的部分，完全没有功率损失。AB类放大器是兼容A类放大器与B类放大器的优势的一种放大器，当没有信号或信号非常小时，晶体管的正负通道常开，当信号是正相信号时，负相通道在信号变强前还是常开的，在信号转强后负通道关闭，当信号是负相信号时，正负通道的工作刚好相反，AB类功率放大器相对于它的效率比以及保真度而言，都优于A类放大器和B类放大器。主放大器103可以为B类放大器或者AB类放大器，峰值放大器(即图2中的104)可以为C类放大器。主放大器103可以一直处于工作状态，峰值放大器104只有到设定的峰值才工作(峰值放大器也称为peak amplifier)。此外，主放大器103和峰值放大器104的饱和功率不相等，主放大器103和峰值放大器104的饱和功率的比值可以为1:2或1:3等。
通过Doherty功放单元100中的Doherty结构，可以大大提高深度回退情况下的发射系统的发射效率，而且，还可以自适应的满足不同等级的发射功率需求，从而实现全功率等级下功率放大器都能够维持在较高的效率下工作。
如图1或图2所示，天线阵列单元200中可以包括多个天线阵子201，天线阵列单元200可以实现波束赋形，波束赋形可以是通过调整天线阵列中每个天线阵子201的加权系数产生具有指向性的波束，从而能够获得明显的阵列增益的过程，因此，波束赋形技术在扩大覆盖范围、改善边缘吞吐量以及干扰抑止等方面有很大的优势。
微控制单元MCU300可以是发送控制指令的组件单元，微控制单元MCU300中可以预先设置有天线阵列单元200和Doherty功放单元100之间协调控制的算法，微控制单元MCU300可以基于该算法发出天线阵列单元200 和/或Doherty功放单元100的控制指令，以控制Doherty功放单元100的输出功率和天线阵列单元200的辐射方向。
如图1或图2所示，为了达到微控制单元MCU300对天线阵列单元200和Doherty功放单元100的协调控制，可以将Doherty功放单元100的控制端和天线阵列单元200的控制端分别与MCU300相连接，同时，Doherty功放单元100的输出端与天线阵列单元200的输入端相连接，这样，微控制单元MCU300可以分别将相应的控制指令发送给Doherty功放单元100和天线阵列单元200，通过控制指令可以控制天线阵列单元200中各个天线的辐射方向，通过控制天线阵列的辐射方向，以及结合波束赋形技术可以调整天线阵列单元200的阵列增益，从而降低射频系统的发射功率，达到节省电量的目的。
此外，为了从根本上控制Doherty功放单元100的输出功率，可以将Doherty功放单元100设置为由多个功率放大器组成的功放单元，具体地，如图2所示，Doherty功放单元100可以由二路功率放大器组成，其中的功率放大器可以是指在给定失真率条件下，能产生最大功率输出以驱动某一负载的放大器，功率放大器可以包括多种，本申请实施例中，二路功率放大器中可以包括主放大器103和峰值放大器104，主放大器103可以为B类放大器或者AB类放大器，峰值放大器104可以为C类放大器等，功率放大器的具体结构可以根据实际情况设定，本申请实施例对此不做限定。此外，根据Doherty结构的功率放大单元的结构特性，Doherty功放单元100中的主放大器103后面包括四分之一波长阻抗线是阻抗变换，目的是在辅助功率放大器工作时，起到将主放大器103的视在阻抗减小的作用，从而保证峰值放大器104工作时和后面的电路组成的有源负载阻抗变低，这样主放大器103输出电流就变大。由于主放大器103连接有四分之一波长阻抗线，为了使两个功率放大器输出同相，在峰值放大器前面也需要设置90°相移。由于微控制单元MCU300可以控制Doherty功放单元100的输出功率，因此，如果想要精准控制Doherty功放单元100的输出功率，就需要对Doherty功放单元100中的二路功率放大器中的一路或二路功率放大器分别进行控制，为此，可以为每路功率放大器均串联一个开关控制器102，即如图2中的第一开关控制器1021和第二开 关控制器1022，这样，微控制单元MCU300可以通过控制Doherty功放单元100中开关控制器102的开启与闭合，控制Doherty功放单元100的发射功率。
在实际应用中，Doherty功放单元和天线阵列单元200通过微控制单元MCU300实现自适应控制，即在移动终端(如手机或平板电脑等终端设备等)和网络侧设备400(如基站等)进行握手通信后，天线阵列单元200通过波束赋形技术可以增强天线阵列单元200中的天线在某方向上的阵列增益，然后，就可以通过控制开关控制器102的开启与闭合，来实现降低Doherty功放单元100的发射功率。例如，微控制单元MCU300控制天线阵列单元200中天线的方向，并在没到达某一个方向时可以基于波束赋形对天线进行阵列增益，如果在某一个方向上，天线阵列单元200的阵列增益变大，则微控制单元MCU300可以向Doherty功放单元100发送控制信号，该控制信号中可以包括开启和/或关闭哪个或哪些开关控制器102，Doherty功放单元100接收到该控制信号后，可以根据控制信号中的内容指示相应的开关控制器102开启或关闭，从而使得射频系统具备最优的发射功率和辐射方向性，减少电量的损耗。
本申请实施例提供一种基于毫米波通信的射频系统包括Doherty功放单元、天线阵列单元和微控制单元MCU，其中：Doherty功放单元的输出端与天线阵列单元的输入端相连接，Doherty功放单元的控制端和天线阵列单元的控制端分别与MCU相连接，该MCU控制天线阵列单元中天线的辐射方向，Doherty功放单元由二路功率放大器组成，二路功率放大器的饱和功率不相等，且每路功率放大器均串联有开关控制器，MCU通过控制Doherty功放单元中开关控制器的开启与闭合，控制Doherty功放单元的发射功率，这样，通过上述射频系统的结构，可以通过控制Doherty功放单元中开关控制器的开启与闭合，来控制Doherty功放单元的发射功率，实现在确保信号质量的前提下，尽可能高的提高功率放大器的效率，同时，通过控制Doherty功放单元的发射功率进而控制射频系统的发射功耗，可以增加移动终端的待机时长。
实施例二
本申请实施例提供又一种基于毫米波通信的射频系统。该基于毫米波通 信的射频系统包含了图1～图2所示的基于毫米波通信的射频系统的全部功能单元，并在其基础上，对其进行了改进，改进内容如下：
如图3所示，基于Doherty结构的功率放大单元的特性，上述二路功率放大器中可以包括主放大器103、峰值放大器104，其中，主放大器103与峰值放大器104并联，且主放大器103与峰值放大器104的饱和功率的比值可以为1:2。另外，主放大器103和峰值放大器104可以组成2路Doherty功放(此时，与主放大器103连接的第一开关控制器1021处于闭合状态，与峰值放大器104连接的第二开关控制器1022也处于闭合状态)，上述组成的2路Doherty功放可以用于大功率发射的情况下，此时，可以利用2路Doherty功放回退的高效率特性，可以大大提升大功率发射情况下的效率值，如图4所示。另外，当与主放大器103连接的第一开关控制器1021处于闭合状态，而与峰值放大器104连接的第二开关控制器1022处于开启状态时，Doherty功放单元100可以形成单功放链路，该单功放链路可以用于低功率等级的发射需求，可以大幅度提高低功率等级的效率值。此外，当与主放大器103连接的第一开关控制器1021处于开启状态，而与峰值放大器104连接的第二开关控制器1022处于闭合状态时，Doherty功放单元100可以形成单功放链路，该单功放链路可以用于中等功率等级的发射需求，可以大幅度提高中等功率等级的效率值。其中，主放大器103可以工作在AB类状态，主放大器103可以保持常开状态。峰值放大器104工作在C类状态，峰值放大器104在低功率下可以关闭，当输出功率升高到一定数值后才会开启。其中的主放大器103可以负责低功率放大，峰值放大器104可以负责峰值功率放大等。
此外，如图3所示，考虑到Doherty功放单元100由二路功率放大器组成，为了使得输入到Doherty功放单元100中的功率分配均匀，可以在Doherty功放单元100的输入端连接二功分器101，这样，二功分器101可以分别与Doherty功放单元100中的每路功率放大器相连接，从而实现将输入信号一分为二的目的，二功分器101的功率分配比可以根据需求灵活设置，即如果主放大器103与峰值放大器104的饱和功率的比值为1:2，则二功分器的功率分配比可以采用1:2的分配方式。通过上述二功分器101可以将输入的功率分配成2个部分，分别输入到每一路功率放大器中，同时，每一路功率放大器 连接有开关控制器102，通过开关控制器102还可以控制相应功率放大器的功率传输与处理，另外，二功分器101的输出端口之间可以保证一定的隔离度和功率损耗，从而可以尽最大可能减少功率的损耗。
另外，如图3所示，该射频系统还包括多个四分之一波长阻抗线，四分之一波长阻抗线可以实现阻抗变换，即将偏置电路的低阻变换为高阻，从而达到高频隔离的目的。基于四分之一波长阻抗线的作用，以及Doherty结构的功放单元的特性，四分之一波长阻抗线可以分别设置于主放大器103的输出端和峰值放大器104的输入端，即主放大器103的输出端设置有第一四分之一波长阻抗线，如图3中的Z 01，峰值放大器104的输入端设置有第三四分之一波长阻抗线，如图3中的Z 03，另外，主放大器103的输出端通过第一四分之一波长阻抗线Z 01与峰值放大器104的输出端连接后还与第二四分之一波长阻抗线(如图3中的Z 02)相连接，其中，四分之一波长阻抗线分别放到两路功率放大器的输入输出端，四分之一波长阻抗线放置在输入端可以起到相位平衡的作用，四分之一波长阻抗线放置在输出端可以起到阻抗牵引和匹配的作用，而且，Z 03可以是50欧姆阻抗的特征网络，而Z 01可以是70.7欧姆特征阻抗网络，而Z 02可以是40.8欧姆特征阻抗网络。
此外，Doherty功放单元100中可以包括两个电源，即第一电源Vcc1和第二电源Vcc2，其中，主放大器103可以连接于第一电源Vcc1，峰值放大器104可以连接于第二电源Vcc2。射频系统中还可以包括多个APT电路，即第一APT电路和第二APT电路，第一APT电路和第二APT电路相互独立，两个独立的APT电路可以分别实现APT功能，从而提高功率放大器的发射效率，其中，第一电源Vcc1还可以连接于第一APT电路，第二电源Vcc2可以连接于第二APT电路。
另外，天线阵列单元200中可以包括多个天线阵子201，其中的天线阵子201可以通过匹配网络合成公共接口，并通过合成的公共接口与Doherty功放单元100的输出端相连接。
如图5所示，天线阵列单元200由m×n个天线阵子201组成，其中的n表示n行，m表示m列。m×n个天线阵子201通过匹配网络合成一个公共的port口，通过同一个port口和Doherty功放单元100的输出端相连接。MUC 通过控制端分别和Doherty功放单元100以及天线阵列单元200相连接，实现协同控制。
在实际应用中，如图6所示，在移动终端和网络侧设备400进行握手通信后，天线阵列单元200通过波束赋形技术可以增强天线阵列单元200中的天线在某方向上的阵列增益，然后，就可以通过控制开关控制器102的开启与闭合，来实现降低Doherty功放单元100的发射功率，从而使得射频系统具备最优的发射功率和辐射方向性，减少电量的损耗。
本申请实施例提供一种基于毫米波通信的射频系统包括Doherty功放单元、天线阵列单元和微控制单元MCU，其中：Doherty功放单元的输出端与天线阵列单元的输入端相连接，Doherty功放单元的控制端和天线阵列单元的控制端分别与MCU相连接，该MCU控制天线阵列单元中天线的辐射方向，Doherty功放单元由二路功率放大器组成，二路功率放大器的饱和功率不相等，且每路功率放大器均串联有开关控制器，MCU通过控制Doherty功放单元中开关控制器的开启与闭合，控制Doherty功放单元的发射功率，这样，通过上述射频系统的结构，可以通过控制Doherty功放单元中开关控制器的开启与闭合，来控制Doherty功放单元的发射功率，实现在确保信号质量的前提下，尽可能高的提高功率放大器的效率，同时，通过控制Doherty功放单元的发射功率进而控制射频系统的发射功耗，可以增加移动终端的待机时长。
实施例三
如图7所示，本申请实施例提供一种发射功率的调整方法，该方法的执行主体可以为移动终端，该移动终端中可以包含基于毫米波通信的射频系统，其中，该移动终端可以如手机、平板电脑等，该移动终端可以为用户使用的移动终端。该方法可以应用于对移动终端中射频系统的发射功率进行调整等处理中。该方法具体可以包括以下步骤：
在步骤S702中，根据网络侧设备的下行信号，确定与该下行信号对应的电平信息。
其中，网络侧设备400可以是用于与移动终端(如手机或平板电脑等终端设备)通信的设备，网络侧设备400可以是全球移动通信系统(Global System  of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)或接入点，或者车载设备、可穿戴设备，未来5G网络中的网络侧设备400或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的网络侧设备400等。
在实施中，移动终端与网络侧设备400建立通信连接后，移动终端可以接收网络侧设备400发送的下行信号，为了更好的控制波束赋形，可以将接收的下行信号转换为电平的数值信息，每个电平的数值可以对应一个功率值，用于显示当前的下行信号的信号强度。由于天线收发信号是互异的过程，所以，可以利用接收的下行信号对应的电平信号的信息作为波束赋形的控制依据，以改善发射性能。
在步骤S704中，基于上述电平信息，调整该移动终端中基于毫米波通信的射频系统中天线阵列的方向。
在实施中，移动终端接收到下行信号，并将该下行信号转换为电平信息后，可以记录该下行信号对应的电平信息，可以将该电平信息与上一次接收到的下行信号对应的电平信息或基准电平信息进行对比，确定本次获取的电平信息中的电平值相较于上一次获取的电平信息或基准电平信息中的电平值增大还是减小，可以根据增大或减小的结果，相应的调整上述射频系统中天线阵列单元200中的各个天线阵子201的方向，例如，如果上一次获取的电平信息或基准电平信息中的电平值增大，则可以继续保持当前的移动方向，调整该射频系统中天线阵列的方向，如果上一次获取的电平信息或基准电平信息中的电平值减小，则可以向与当前的移动方向相反的方向，调整该射频系统中天线阵列的方向等。
在步骤S706中，如果调整天线阵列的方向后，接收的网络侧设备400的下行信号对应的电平值增大，则通过该射频系统中MCU控制该射频系统中Doherty功放单元降低发射功率。
在实施中，在移动终端和网络侧设备400建立通信的过程中，移动终端 可以通过改变天线阵列单元200发出的波束的方向，从而找到接收的下行信号对应的电平的最大值(即波束方向就是网络侧设备400的天线方向)，确定天线阵列单元200发出的波束方向后，便可通过调节天线阵列的波束宽度，使得发射信号更集中，从而提高天线阵列在此方向上的阵列增益。在优化了天线阵列单元200中的天线的方向性和波束宽度后，微控制单元MCU300便可以根据预设定的自适应算法，控制Doherty功放单元100中的二个开关控制器102的通断情况，从而，同步控制天线阵列单元200中功率放大器的工作状态，以此来降低移动终端的发射功率，从而实现最优的效率值。
本申请实施例提供一种发射功率的调整方法，该方法可以应用于基于毫米波通信的射频系统，该射频系统可以包括Doherty功放单元、天线阵列单元和微控制单元MCU，其中：Doherty功放单元的输出端与天线阵列单元的输入端相连接，Doherty功放单元的控制端和天线阵列单元的控制端分别与MCU相连接，该MCU控制天线阵列单元中天线的辐射方向，Doherty功放单元由二路功率放大器组成，二路功率放大器的饱和功率不相等，且每路功率放大器均串联有开关控制器，MCU通过控制Doherty功放单元中开关控制器的开启与闭合，控制Doherty功放单元的发射功率，这样，通过上述射频系统的结构，可以通过控制Doherty功放单元中开关控制器的开启与闭合，来控制Doherty功放单元的发射功率，实现在确保信号质量的前提下，尽可能高的提高功率放大器的效率，同时，通过控制Doherty功放单元的发射功率进而控制射频系统的发射功耗，可以增加移动终端的待机时长。
实施例四
如图8所示，本申请实施例提供一种发射功率的调整方法，该方法的执行主体可以为移动终端，该移动终端中可以包含如上述实施例一和实施例二中的基于毫米波通信的射频系统，其中，该移动终端可以如手机、平板电脑等，该移动终端可以为用户使用的移动终端。该方法可以应用于对移动终端中射频系统的发射功率进行调整等处理中。该方法具体可以包括以下步骤：
在步骤S802中，根据网络侧设备400的下行信号，确定与该下行信号对应的电平信息。
在步骤S804中，基于上述电平信息，调整该移动终端中基于毫米波通信的射频系统中天线阵列的方向。
在步骤S806中，如果调整天线阵列的方向后，接收的网络侧设备400的下行信号对应的电平值增大，则通过该射频系统中MCU控制该射频系统中Doherty功放单元降低发射功率。
上述步骤S802～步骤S806的步骤内容分别与上述实施例三中的步骤S702～步骤S706的步骤内容相同，步骤S802～步骤S806的具体处理过程可以分别参见上述步骤S702～步骤S706的相关内容，在此不再赘述。
在步骤S808中，如果调整天线阵列的方向后，接收的网络侧设备400的下行信号对应的电平值减小，则调整该射频系统中天线阵列的方向。
在实施中，在移动终端和网络侧设备400建立通信的过程中，如果调整天线阵列的方向后，接收的网络侧设备400的下行信号对应的电平值减小，则表明当前天线阵列单元200发出的波束在当前方向上的阵列增益并没有提高，此时，可以继续调整该射频系统中天线阵列的方向，找到接收的下行信号对应的电平的最大值(即波束方向就是网络侧设备400的天线方向)。确定天线阵列单元200发出的波束方向后，便可通过调节天线阵列的波束宽度，使得发射信号更集中。同时，微控制单元MCU300可以根据预设定的自适应算法，控制Doherty功放单元100中的二个开关控制器102的通断情况，从而，同步控制天线阵列单元200中功率放大器的工作状态，以此来降低移动终端的发射功率，实现最优的效率值。
本申请实施例提供一种发射功率的调整方法，该方法可以应用于基于毫米波通信的射频系统，该射频系统可以包括Doherty功放单元、天线阵列单元和微控制单元MCU，其中：Doherty功放单元的输出端与天线阵列单元的输入端相连接，Doherty功放单元的控制端和天线阵列单元的控制端分别与MCU相连接，该MCU控制天线阵列单元中天线的辐射方向，Doherty功放单元由二路功率放大器组成，二路功率放大器的饱和功率不相等，且每路功率放大器均串联有开关控制器，MCU通过控制Doherty功放单元中开关控制器的开启与闭合，控制Doherty功放单元的发射功率，这样，通过上述射频系统的结构，可以通过控制Doherty功放单元中开关控制器的开启与闭合， 来控制Doherty功放单元的发射功率，实现在确保信号质量的前提下，尽可能高的提高功率放大器的效率，同时，通过控制Doherty功放单元的发射功率进而控制射频系统的发射功耗，可以增加移动终端的待机时长。
