通信装置
本申请要求于2018年1月31日提交中国专利局、申请号为2018101000702，发明名称为“通信装置”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
本发明涉及通信技术领域，特别涉及多天线技术。
背景技术
随着长期演进(Long Term Evolution，LTE)和第五代(5G，5th Generation)网络不断发展，多天线技术被提出，例如多输入多输出(multiple input multiple output，MIMO)技术。采用多天线技术能够有效提高系统容量，对于下行多发，可以利用基站侧多个发射通道和天线阵列赋型波束以实现体现发射出的信号分别指向不同的终端用户从而提升下行的容量；对于上行的多收，会提升基站的解调灵敏度从而提升上行容量，也可以根据终端发射过来的信号进行上行接收的赋型波束以达到只接收终端发射过来方向的信号并抑制周围其它信号的干扰进一步提升上行系统容量。
多天线技术在提高系统容量的同时，也给运营商带来了功耗的增加，采用多天线技术时如何降低系统功耗是一个亟待解决的问题。
发明内容
本申请实施例提供一种通信装置，可以在采用多天线技术时降低系统的功耗。
第一方面，本发明实施例提供了一种通信装置，包括相位校正单元、第一射频通道、第一模拟电桥、第二射频通道和第二模拟电桥，该第一模拟电桥包括第一输入端和至少两个第一输出端，该第一输入端与该第一射频通道相连，每个该第一输出端连接至一个第一天线阵列；第一输出端与第一天线阵列之间的连接关系可以是直接连接，也可以为间接连接，间接连接是指在第一输出端和第一天线阵列之间设置其它器件，通过其它器件连接在第一输出端和第一天线阵列之间。第一输出端和第一天线阵列之间是一一对应的连接关系，不同的第一输出端所对应连接的第一天线阵列也是不同的。该第二模拟电桥包括第二输入端和至少两个第二输出端，该第二输入端与该第二射频通道相连，每个该第二输出端连接至一个第二天线阵列；第二输出端和第二阵列天线之间的连接方式可以与第一输出端和第一天线阵列之间的连接方式相同。

本申请通过第一模拟电桥和第二模拟电桥的设置，使得第一射频通道和第二射频通道 的信号分别经过第一模拟电桥和第二模拟电桥后，被分为至少两个第一分信号和至少两个第二分信号，并利用相位校正单元对信号的相位调整，使得至少两个第一分信号分别驱动至少两个第一天线阵列，至少两个第二分信号分别驱动至少两个第二天线阵列，这样一个射频通道的信号可以分解为至少两路信号并能够驱动至少两个天线阵列，因此，本申请提供的通信装置中的射频通道和对应覆盖的天线阵列的数量比为1：N，N大于等于2，可以实现在射频通道数量少的情况下，能够覆盖更多的天线阵列，射频通道少，能耗就低，具有节能的效果。一种实施方式中，该通信装置为RRU，第一、第二天线阵列不包含在通信装置中。
一种实施方式中，该通信装置还包括：天线单元，该天线单元包括该至少两个该第一天线阵列和该至少两个该第二天线阵列。本实施例具体保护一种RRU和天线组合成的通信装置，即通信装置除了包括相位校正单元、第一射频通道、第一模拟电桥、第二射频通道和第二模拟电桥，还包括第一、第二天线阵列。
第二方面，本申请实施例提供的通信装置包括天线单元、第一模拟电桥和第二模拟电桥，该天线单元包括至少两个第一天线阵列和至少两个第二天线阵列；该第一模拟电桥包括第一输入端和至少两个第一输出端，该第一输入端与第一射频通道相连，每个该第一输出端连接至一个该第一天线阵列；该第二模拟电桥包括第二输入端和至少两个第二输出端，该第二输入端与第二射频通道相连，每个该第二输出端连接至一个该第二天线阵列；
第一信号通过该第一射频通道发送至该第一输入端，通过该第一模拟电桥分成至少两路第一分信号，该至少两路第一分信号分别从该至少两个第一输出端输出到至少两个该第一天线阵列；第二信号通过该第二射频通道发送至该第二输入端，通过该第二模拟电桥分成至少两路第二分信号，该至少两路第二分信号分别从该至少两个第二输出端输出到至少两个该第二天线阵列；该至少两路第一分信号中的第一路第一分信号和该至少两路第二分信号中的第一路第二分信号通过耦合器被耦合至该相位校正单元，该相位校正单元将调整后的信号发送至对应的射频通道，以使该第一路第一分信号和该第一路第二分信号的相位相同。
具体而言，本实施方式所涉及的通信装置为一种天线系统，不包括第一射频通道和第二射频通道，只包括天线单元、第一模拟电桥和第二模拟电桥。天线系统中的第一模拟电桥的一个输入端的第一信号可以被分为至少两路第一分信号，这样一路输入信号可以输送至至少两个天线阵列，具有节能功效。
一种实施方式中，该相位校正单元将调整后的信号发送至对应的射频通道，包括：
该相位校正单元调整该第一信号并将调整后的该第一信号发送至该第一射频通道；或者，该相位校正单元调整该第二信号并将调整后的该第二信号发送至该第二射频通道；或者，该相位校正单元调整该第一信号和该第二信号，并将调整后的该第一信号发送至该第一射频通道，将调整后的该第二信号发送至该第二射频通道。上述实施方式包括三种具体的实施例，其一为相位校正单元调整第一信号，并将调整后的信号发给第一射频通道，不限定相位校正单元是否调整第二信号；其二为相位校正单元调整第二信号，并将调整后的信号发给第二射频通道，不限定相位校正单元是否调整第一信号；其三为相位校正单元即调整第一信号又调整第二信号，并将调整后的信号发给第一射频通道和第二射频通道。本 实施方式限定了相位校正单元对信号进行相位校正的具体方式。
一种实施方式中，该相位校正单元周期性地对第一信号和第二信号中进行相位调整，周期性地发送调整后的信号至对应的射频通道。周期性地调整是指相位校正单元每一次调整相位之间间隔预设的时间，形成调节周期，调节周期的设置受到通信装置所处的环境温度、湿度、地埋位置等因素影响。通信装置在出厂之前，就设置好调节周期，通信装置应用在通信设备中，通信设备内可以设置计时单元，计时单元可以为硬件，例如计时器芯片，也可以通过软件来实现。计时单元用于设置调节周期，并将调节周期信号传送至相位校正单元。本实施方式采用周期性地调整相位，使得通信装置的更具节能性。
一种实施方式中，该第一路第一分信号和该至少两路第一分信号中的第二路第一分信号之间相位差为第一预设值；该第一路第二分信号和该至少两路第二分信号中的第二路第二分信号之间的相位差为第二预设值。
具体而言，该至少两个第一输出端之其中一个为第一端口，该至少两个第一输出端之其中另一个为第二端口，该第一路第一分信号从该第一端口输出，该第二路第一分信号从该第二端口输出；该第一端口与第一路第一移相器相连，该第一路第一移相器用于调整该第一路第一分信号，以使该第一路第一分信号和该第二路第一分信号之间的相位差至该第一预设值；和/或该第二端口与第二路第一移相器相连，该第二路第一移相器用于调整该第二路第一分信号，以使该第一路第一分信号和该第二路第一分信号之间的相位差至该第一预设值。概括而言，第一端口和第二端口可以分别都设置移相器，也可以只在其中一个端口处设置移相器。
相似地，该至少两个第二输出端之其中一个为第三端口，该至少两个第二输出端之其中另一个为第四端口，该第一路第二分信号从该第三端口输出，该第二路第二分信号从该第四端口输出；该第三端口与第一路第二移相器相连，该第一路第二移相器用于调整该第一路第二分信号，以使该第一路第二分信号和该第二路第二分信号之间的相位差至该第一预设值；和/或该第四端口与第二路第二移相器相连，该第二路第二移相器用于调整该第二路第二分信号，以使该第一路第二分信号和该第二路第二分信号之间的相位差至该第二预设值。概括而言，第三端口和第四端口可以分别都设置移相器，也可以只在其中一个端口处设置移相器。
具体而言，通过预期相位差(即第一预设值和第二预设值)，使得所有射频通道对应的天线阵列合成的波束的垂直指向与关闭射频通道前相同，从而没有改变小区。不改变小区，避免了UE切换或者重新接入，保证了用户体验。
该第一预设值和/或第二预设值可以为90度，在第一分信号之间形成相位差，可以保证天线的辐射性能。
一种实施方式中，该第一预设值与该第二预设值相同，换言之，第一分信号之间的相位差和第二分信号之间的相位差是一致的，均为同样的预设值，有利于通信装置的天线阵列覆盖信号的规律性和稳定性。
上述第一移相器和第二移相器可以为固定移相器或者可调移相器，可以为单独电子器件，也可以与其它元件集成在一起，例如集成在耦合器中的移相单元。然而，调节相位差不限于通过移相器，本申请实施例还可以通过其它的方式实现，例如：模拟电桥本身就可 以输出端口的相位差，即利用电桥内的电路架构实现至少一个第一输出端和至少一个第二输出端的相位差。
一种实施方式中，该第一输入端与第一功率放大器相连，该第一功率放大器用于放大该第一信号；该第二输入端与第二功率放大器相连，该第二功率放大器用于放大该第二信号。第一功率放大器即可以设置在第一射频通道中，也可以设置在第一射频通道和第一模拟电桥之间。相似地，第二输入端也可以设置功率放大器。功率放大器用于对射频信号功率放大，可以提升天线阵列辐射的信号强度。
一种实施方式中，该第一模拟电桥和/或该第二模拟电桥是单个模拟电桥或者模拟电桥组。本实施方式包括三种具体实施例，第一实施例为：第一模拟电桥是单个模拟电桥或者模拟电桥组；第二实施例为：该第二模拟电桥是单个模拟电桥或者模拟电桥组；第三实施例为：该第一模拟电桥和该第二模拟电桥均是单个模拟电桥或者模拟电桥组。
为了方便理解，一种具体实施方式中，该第一输出端的数量为两个，该两个第一输出端分别为第一端口和第二端口，该第二输出端的数量为两个，该两个第二输出端分别为第三端口和第四端口，该相位校正单元将调整后的信号发送至对应的射频通道后，对应的射频通道指第一射频通道和第二射频通道，该第一端口的该第一分信号的相位和该第三端口的该第二分信号的相位相同。本实施例提供了一分为二的第一模拟电桥和第二模拟电桥的设计，即每个射频通道对应驱动两个天线阵列。信号处理的更容易，相位校正单元也比较容易选择信号来校正，相位校正单元可以参考第一端口和第三端口耦合回的信号，或者相位校正单元也可以参考第二端口和第四端口耦合回的信号。第一、第二、第三、第四端口均连接至相位校正单元，相位校正单元根据需要选择两路信号做调节。相位校正单元与第一射频通道和第二射频通道电连接，用于将调整后的信号输送至第一射频通道和第二射频通道。
一种实施方式中，该第二端口的该第一分信号的相位和该第四端口的该第二分信号的相位相同。
一种实施方式中，通信装置具有至少两个射频通道，第一模拟电桥和第二模拟电桥的输入端的数量也是至少两个，形成多射频通道至天线阵列一对一驱动的关系。具体而言，该第一输入端、该第一射频通道和该第一输出端的数量均为N，N大于等于2，所有的该第一射频通道均打开的状态下，该第一射频通道、该第一输入端和该第一输出端一一对应连接形成N路并列的第一信号支路。
相应地，该第二输入端、该第二射频通道和该第二输出端的数量均为N，N大于等于2，所有的该第二射频通道均打开的状态下，该第二射频通道、该第二输入端和该第二输出端一一对应连接形成N路并列的第二信号支路。
具体而言，通信装置还包括信号处理单元，所有的该第一射频通道均打开的状态下，该信号处理单元对所有的该第一射频通道的信号进行预加权处理，以实现该N个第一射频通道的信号分别从该N路并列的第一信号支路传送至不同的天线阵列。所有的该第二射频通道均打开的状态下，该信号处理单元对所有的该第二射频通道的信号进行预加权处理，以实现该N个第二射频通道的信号分别从该N路并列的第二信号支路传送至不同的天线阵列。
该信号处理单元通过反补电桥的方式对该第一射频通道的信号进行预加权处理，反补电桥是第一模拟电桥的逆矩阵，举例说明，一种实施方式中，返补电桥的算法如下：
该第一模拟电桥的信号的映射阵列为：

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
本申请实施例的技术方案可以适用于如图1所述的系统10。该系统包括射频装置101和天线装置102，射频装置101和天线装置102连接。
射频装置101可以用于将接收到的数字信号转换成射频信号，将射频信号发送至天线装置102，或者从天线装置102接收射频信号，并将射频信号转换成数字信号，并传送至基带控制单元。天线装置102可以将接收到的射频信号发射出去或者接收外界的射频信号并传送至射频装置101。
图1中的射频装置101和天线装置102物理上可以分开，例如，射频装置101可以是射频拉远单元(radio remote unit，RRU)或者射频单元(radio frequency unit，RFU)，天线装置可以是多根天线，该多根天线可以布局在一副天线罩内。射频装置101和天线装置102物理上可以集成在一起，例如，系统10可以是有源天线单元(Active Antenna Unit，AAU)。
图2是一种实施方式中的系统10的示意图，包括射频装置101和天线装置102。射频装置101可以包括收发器，收发器可以为发射机TX和接收机RX。请参阅图2，一种实施方式中，发射机TX包括依次电连接的调制器11、上变频器12、功率放大器13、带通滤波器14，可选的，调制器11和上变频器12分别与一个振荡器15连接。基带控制单元发送的基带信号进入射频装置101后，依次经过调制器11、上变频器12、功率放大器13和带通滤波器14后，发送给天线装置102。接收机RX包括依次电连接的带通滤波器16、低噪放大器17、下变频器18和解调制器19，可选的，下变频器18和解调制器19分别与一个振荡器15连接。如图2所示，调制器11和解调制器19连接一个振荡器15，上变频器12和下变频器18连接一个振荡器15，需要说明的是，这仅仅是一个示例，调制器11和解调制器19可以连接不同的振荡器，上变频器12和下变频器18可以连接不同的振荡器，本申请实施例对此不作限定。天线信号进入射频装置101后，依次经过带通滤波器16、低噪放大器17、下变频器18和解调制器19后形成基带信号发送给基带控制单元。需要说明的是，图2仅仅是射频装置101和天线装置102的一种示例，本申请实施例中，射频装置101中的电子器件、电子器件的数量以及电子器件之间的连接关系不限于此。
图3a是一种实施方式中的系统10的示意图。射频装置101可以包括多个射频通道，例如射频通道1011，1012，1013和1014。该多个射频通道可以分别进行接收和/或发送以实现射频装置的多收多发。例如：2T2R的射频装置可以包括2个射频通道，该2个射频通道可以进行接收和/或发送以实现射频装置的2发2收。需要说明的是，这里射频通道可以指射频装置中的电路通道，例如如图2所示收发器中的电路通道，该电路通道可以包括例如图2所示的电路架构中的一个或者多个电子器件，多个射频通道可以共用电路通道，也 可以每个射频通道都包括单独的电路通道。或者，这里的射频通道可以指射频装置中的逻辑通道，该逻辑通道中可以完成基带信号与射频信号的转换。
天线装置102可以包括多个天线阵列，例如天线阵列1021，1022，1023和1024。这里一个天线阵列可以称为一根天线。每个射频通道与一个对应的天线阵列连接，每个射频通道可以将射频信号发送至一个对应的天线阵列，由该对应的天线阵列发射到空中。例如，如图3a所示，射频通道1011与天线阵列1021连接，射频通道1011可以将射频信号发送至天线阵列1021；射频通道1012与天线阵列1022连接，射频通道1012将射频信号发送至天线阵列1022；射频通道1013与天线阵列1023连接，射频通道1013将射频信号发送至天线阵列1023；射频通道1014与天线阵列1024连接，射频通道1014将射频信号发送至天线阵列1024。
每个天线阵列由一个或者多个天线阵子组成。需要说明的是，射频通道与对应的天线阵列连接，可以表示该射频通道与该天线阵列中的每个天线阵子相连接；射频通道将射频信号发送至对应的天线阵列，可以表示该射频通道将射频信号发送至该天线阵列中的每个天线阵子。该射频通道将射频信号发送至该天线阵列，可以理解为射频信号经过射频通道发送至天线阵列，或者表述为射频通道驱动该天线阵列。1个天线阵列包括N(N为大于等于1的整数)个天线阵子，也可以表示为1个射频通道驱动N天线阵子或者简称为1驱N。
例如，结合图3a和图3b，以天线阵列1021为例进行说明。图3b中，天线阵子A1和天线阵子B1形成正负45度交叉极化方向布置，同样地，天线阵子A2和天线阵子B2形成正负45度交叉极化方向布置；天线阵子A3和天线阵子B3亦形成正负45度交叉极化方向布置。天线阵子A1、A2、A3共同形成一个天线阵列，天线阵子B1、B2、B3共同形成另一个天线阵列，这两个不同的天线阵列可以由不同的射频通道驱动。天线阵列1021可以由天线阵子A1、A2、A3共同形成，射频通道1011与天线阵列1021相连接，即射频通道1011与天线阵子A1，天线阵子A2和天线阵子A3相连接。天线阵列1022，1023，1024与天线阵列1021类似，在此不再赘述。
如图3a所示，射频通道和天线阵列连接形成一一对应的架构，例如，射频通道1011与天线阵列1021对应，射频通道1012与天线阵列1022对应。在系统10中，每个射频通道都会产生一定的功耗，射频通道的数量越多，系统的功耗越大。当用户容量需求较大，可以开启所有或者多个射频通道；当用户容量需求较小时，仍然开启所有或者多个射频通道会带来不必要的功耗，此时需要一种能够降低功耗的方法。一种解决方式是选择关闭部分射频通道。但是，由于射频通道与天线阵列的一一对应的关系，当关闭其中部分射频通道时，该部分射频通道对应的天线阵列也随之关闭。天线阵列的数量会影响系统的覆盖性能，在系统保持相同的功率下，天线阵列越多，系统的覆盖越好；反之，天线阵列越少，系统的覆盖越差。故该解决方式虽然通过关闭射频通道实现了降低功耗，但是导致系统的覆盖性能明显下降。
基于上述问题，本申请实施例提出了一种能够降低功耗的方案。当系统10的容量需求较小时，可以关闭部分射频通道，改变射频通道与天线阵列之间的一一对应关系，不关闭该部分射频通道对应的天线阵列，从而既能降低系统功耗，又不会使得覆盖明显下降。
下面具体对本申请中的方案进行介绍。
如图4和图5所示，为本申请实施例提供的一种实施方式中的系统10。图4中示意出的射频装置101可以实现图2和图3a中射频装置101的相同或者类似的功能，图4中示意出的射频装置101包括相位校正单元20、第一射频通道30和第二射频通道50，第一射频通道30和第二射频通道50可以实现图3a中射频通道1011、1012、1013或者1014的相同或者类似的功能。
图4中示意出的天线装置102可以实现图2和图3a中天线装置102的相同或者类似的功能。图4中示意出的天线装置102包括多个第一天线阵列71和多个第二天线阵列72，第一天线阵列71和第二天线阵列72可以实现图3a中天线阵列1021、1022、1023或者1024的相同或者类似的功能。
与图3a中有所不同，图4中射频通道与天线阵列之间并非一一对应的关系。图4示意出的系统10还包括电桥单元103。电桥单元103包括第一模拟电桥40和第二模拟电桥60。
所述第一模拟电桥40包括第一输入端41和至少两个第一输出端42，所述第一输入端41与所述第一射频通道30相连，每个所述第一输出端42连接至一个第一天线阵列71。第一输出端42和第一天线阵列71之间是一一对应的连接关系，不同的第一输出端42连接到不同的第一天线阵列71，形成多路并列的天线架构。
所述第二模拟电桥60包括第二输入端61和至少两个第二输出端62，所述第二输入端62与所述第二射频通道50相连，每个所述第二输出端62连接至一个第二天线阵列72；第二输出端62和第二天线阵列72之间是一一对应的连接关系，不同的第二输出端62连接到不同的第二天线阵列72，形成多路并列的天线架构。
需要说明的是，第一输出端42与第一天线阵列71之间可以直接连接，也可以间接连接，间接连接时，第一输出端42和第一天线阵列71之间可以设置其它器件。第二输出端62与第二天线阵列72之间可以直接连接，也可以间接连接，间接连接时，第一输出端42和第一天线阵列71之间可以设置其它器件。
本实施方式中，通信装置从信号源(例如:基带控制单元)接收第一信号和第二信号。第一信号通过所述第一射频通道30发送至所述第一输入端41，通过第一输入端41进入第一模拟电桥40后，第一信号通过所述第一模拟电桥40分成至少两路第一分信号，所述至少两路第一分信号分别从所述至少两个第一输出端42输出到至少两个所述第一天线阵列71；第二信号通过所述第二射频通道50发送至所述第二输入端61，通过第二输入端61进入第二模拟电桥60后，第二信号通过所述第二模拟电桥60分成至少两路第二分信号，所述至少两路第二分信号分别从所述至少两个第二输出端62输出到至少两个所述第二天线阵列72。
所述至少两路第一分信号中的第一路第一分信号和所述至少两路第二分信号中的第一路第二分信号通过耦合器80被耦合至所述相位校正单元20。一个耦合器80位于所述第一路第一分信号对应的第一输出端，和第一路第一分信号对应的第一天线阵列之间；另一个耦合器80位于所述第一路第二分信号对应的第二输出端，和第一路第二分信号对应的第二天线阵列之间。此处所述第一路第一分信号可以为至少两路第一分信号中的任意一路，同样，第一路第二分信号可以为至少两路第二分信号中的任意一路。
相位较正单元20参考第一路第一分信号和第一路第二分信号的相位，对输入射频通道的信号的相位做调整，所述相位校正单元20将调整后的信号发送至对应的射频通道，以使所述第一路第一分信号和所述第一路第二分信号的相位相同。
通过模拟电桥和相位校正单元的设置，使得一个射频通道的信号可以分解为至少两路信号并能够驱动至少两个天线阵列，具体地，射频通道和对应覆盖的天线阵列的数量比为1：N，N大于等于2，可以实现利用较少的射频通道驱动较多的天线阵列。通过减少射频通道的数量而不减少天线阵列的数量以降低系统功耗，却保证系统的覆盖性能不会明显下降。
一种实施方式中，所述相位校正单元20将调整后的信号发送至对应的射频通道，包括：
所述相位校正单元20调整所述第一信号并将调整后的所述第一信号发送至所述第一射频通道30；或者
所述相位校正单元20调整所述第二信号并将调整后的所述第二信号发送至所述第二射频通道50；或者
所述相位校正单元20调整所述第一信号和所述第二信号，并将调整后的所述第一信号发送至所述第一射频通道30，将调整后的所述第二信号发送至所述第二射频通道50，即相位校正单元即调整第一信号又调整第二信号，并将调整后的信号发给第一射频通道30和第二射频通道50。
本实施方式限定了相位校正单元对信号进行相位校正的具体方式，可以根据不同的使用环境或需求对相位校正单元做设置，对应执行上述相应的校正方式，从而能够实现灵活进行相位校正
一种实施方式中，所述相位校正单元20周期性地对第一信号和第二信号中进行相位调整，发送调整后的信号至对应的射频通道。周期性地调整是指相位校正单元每一次调整相位之间间隔预设的时间，形成调节周期。调节周期的设置可以受到系统10所处的环境，例如温度、湿度、地理位置等因素影响，在不同的环境，例如温度、湿度、地理位置下，系统10可以设置不同的调节周期；或者，调节周期可以是固定的，例如射频装置101在出厂之前，就设置好调节周期。调节周期可以通过在射频装置101内设置计时单元来实现，计时单元可以为硬件，例如计时器芯片，计时单元也可以通过软件来实现。计时单元用于设置调节周期，并将调节周期信号传送至相位校正单元20。本实施方式采用周期性地调整相位，一方面避免过于频繁得进行相位校正，节约资源；另一方面避免经过过长时间，第一分信号或者第二分信号的相位发生变化导致第一路第一分信号和第一路第二分信号的相位不相同，而影响系统10的性能，例如覆盖或者容量。
一种实施方式中，所述第一路第一分信号和所述至少两路第一分信号中的第二路第一分信号之间相位差为第一预设值；所述第一路第二分信号和所述至少两路第二分信号中的第二路第二分信号之间的相位差为第二预设值。
这里第二路第一分信号可以是所述至少两路第一分信号中除了第一路第一分信号以外的任意一路。也就是说，所述至少两路第一分信号中每一路与所述第一路第一分信号之间均可以有预设的相位差，所述至少两路第一分信号中每一路与所述第一路第一分信号之间的预设的相位差可以相同或者不同。例如，第一路第一分信号与其他路第一分信号之间的 相位差均为90度；或者，第一路第一分信号与其他路第一分信号之间的相位差分别是90度，180度，270度···。所述第一路第二分信号和所述至少两路第二分信号中的第二路第二分信号之间的相位差为第二预设值与上类似，在此不再赘述。
所述第一预设值可以通过第一模拟电桥40来实现，所述第二预设值可以通过第二模拟电桥60来实现。例如第一模拟电桥40为90度的2输入2输出的模拟电桥，第一信号经过第一模拟电桥后，输出的两路第一分信号之间具有90度的相位差。
通过第一预设值和第二预设值，使得所述至少两个所述第一天线阵列71和所述至少两个所述第二天线阵列72在只有射频通道30和射频通道50(关闭部分射频通道后)的驱动合成的波束的垂直指向，和每个第一天线阵列71和每个第二天线阵列72分别由一个射频通道驱动下(关闭射频通道前)合成的波束的垂直指向相同。从而关闭射频通道前后，小区没有发生变化，避免了UE切换或者重新接入，保证了用户体验。
请参阅图5，具体而言，所述至少两个第一输出端42之其中一个为第一端口421，所述至少两个第一输出端42之其中另一个为第二端口422，所述第一路第一分信号从所述第一端口421输出，所述第二路第一分信号从所述第二端口422输出；所述第一端口421与第一路第一移相器91相连，所述第一路第一移相器91用于调整所述第一路第一分信号，以使所述第一路第一分信号和所述第二路第一分信号之间的相位差至所述第一预设值；和/或所述第二端口422与第二路第一移相器相连92，所述第二路第一移相器92用于调整所述第二路第一分信号，以使所述第一路第一分信号和所述第二路第一分信号之间的相位差至所述第一预设值。
也就是说，第一端口421和第二端口422可以分别设置移相器91和移相器92，移相器91对第一路第一分信号进行相位调整，移相器92对第二路第一分信号进行相位调整，从而使得第一路第一分信号和第二路第一分信号之间的相位差至所述第一预设值；或者，可以只在第一端口421处设置移相器91，移相器91对第一路第一分信号进行相位调整，第二路第一分信号不进行相位调整，从而使第一路第一分信号和第二路第一分信号之间的相位差至所述第一预设值；或者，可以只在第二端口422处设置移相器92，移相器92对第二路第一分信号进行相位调整，第一路第一分信号不进行相位调整，从而使第一路第一分信号和第二路第一分信号之间的相位差至所述第一预设值。概括而言，要调整两路第一分信号之间的相位差，可以分别用移相器调整两路第一分信号，或者可以只用移相器调整其中一路第一分信号。
相似地，所述至少两个第二输出端62之其中一个为第三端口621，所述至少两个第二输出端62之其中另一个为第四端口622，所述第一路第二分信号从所述第三端口621输出，所述第二路第二分信号从所述第四端口622输出；所述第三端口621与第一路第二移相器93相连，所述第一路第二移相器93用于调整所述第一路第二分信号，以使所述第一路第二分信号和所述第二路第二分信号之间的相位差至所述第一预设值；和/或所述第四端口622与第二路第二移相器94相连，所述第二路第二移相器94用于调整所述第二路第二分信号，以使所述第一路第二分信号和所述第二路第二分信号之间的相位差至所述第二预设值。
也就是说，第三端口621和第四端口622可以分别设置移相器93和移相器94，移相器93对第一路第二分信号进行相位调整，移相器94对第二路第二分信号进行相位调整， 从而使得第一路第二分信号和第二路第二分信号之间的相位差至所述第二预设值；或者，可以只在第三端口621处设置移相器93，移相器93对第一路第二分信号进行相位调整，第二路第二分信号不进行相位调整，从而使第一路第二分信号和第二路第二分信号之间的相位差至所述第二预设值；或者，可以只在第四端口622处设置移相器94，移相器94对第二路第二分信号进行相位调整，第一路第二分信号不进行相位调整，从而使第一路第二分信号和第二路第二分信号之间的相位差至所述第二预设值。概括而言，要调整两路第二分信号之间的相位差，可以分别用移相器调整两路第二分信号，或者可以只用移相器调整其中一路第二分信号。
一种实施方式中，所述第一预设值与所述第二预设值相同。具体可以包括以下两种情况：
(1)至少两路第一分信号中的每一路与所述第一路第一分信号之间的相位差相同，为第一预设值，至少两路第二分信号中的每一路与所述第一路第二分信号之间的相位差相同，为第二预设值，第一预设值与第二预设值相同。例如，第一路第一分信号与其他路第一分信号之间的相位差均为90度，第一路第二分信号与其他路第二分信号之间的相位差也为90度。
(2)至少两个第一分信号中的每一路与所述第一路第一分信号之间均有相位差，但该相位差不同；至少两个第二分信号中的每一路与所述第一路第二分信号之间均有相位差，但该相位差不同；但是至少两个第一分信号中的每一路与所述第一路第一分信号之间相位差的集合与至少两个第二分信号中的每一路与所述第一路第二分信号之间相位差的集合是相同的。例如，第一路第一分信号与其他路第一分信号之间的相位差分别是90度，180度，270度···；第一路第二分信号与其他路第二分信号之间的相位差同样分别是90度，180度，270度···。
由于第一路第一分信号和第一路第二分信号的相位相同，通过所述第一预设值与所述第二预设值相同，使得其他路第一分信号的相位的集合和其他路第二分信号的相位的集合是相同的，也就是说，多路第一分信号和多路第二分信号是对应相同的。例如第一路第一分信号和第一路第二分信号的相位均是0度，其他路第一分信号的相位是90度，180度，270度···，其他路第二分信号的相位是90度，180度，270度···。这样能够提高系统10的规律性和稳定性，更好得控制多个第一天线阵列和多个第二天线阵列合成的波束的垂直指向与关闭射频通道前相同，以实现关闭射频通道前后小区没有发生变化。避免UE切换或者重新接入，保证了用户体验。
上述移相器可以为固定移相器或者可调移相器，可以为单独电子器件，也可以与其它元件集成在一起，例如集成在耦合器中的移相单元，或者集成在模拟电桥中。然而，调节相位差不限于通过移相器，本申请实施例还可以通过其它的方式实现，例如：模拟电桥本身就可以输出端口的相位差，即利用电桥内的电路架构实现至少一个第一输出端和至少一个第二输出端的相位差。
如图5所示，一种实施方式中，所述第一输入端41与第一功率放大器411相连，所述第一功率放大器411用于放大所述第一信号；所述第二输入端61与第二功率放大器611相连，所述第二功率放大器611用于放大所述第二信号。第一功率放大器411即可以设置在 第一射频通道30内，也可以设置在第一射频通道30和第一模拟电桥40之间。功率放大器用于对射频信号功率放大，可以提升信号强度。
一种实施方式中，所述第一模拟电桥40和/或所述第二模拟电桥60是单个模拟电桥或者模拟电桥组。本实施方式包括三种，第一：第一模拟电桥40是单个模拟电桥或者模拟电桥组；第二：所述第二模拟电桥60是单个模拟电桥或者模拟电桥组；第三：所述第一模拟电桥40和所述第二模拟电桥60均是单个模拟电桥或者模拟电桥组。
需要说明的是，为了描述方便，图4和图5以2个射频通道，电桥单元103包括2个模拟电桥为例进行了说明，实现中，可以有1个，2个或者以上的射频通道，电桥单元103可以包括1个模拟电桥，或者2个以上的模拟电桥。当电桥单元103包括2个以上的模拟电桥时，每个模拟电桥的输出的多路信号中的任意一路被耦合回相位校正单元20，相位校正单元20会调整所述2个以上模拟电桥对应的输出端的信号中的一个或者多个，以使所述2个以上模拟电桥的输出端的多路信号中的对应一路的相位相同；并且所述2个以上模拟电桥中的每个模拟电桥的1个或者多个输出端都具有移相器，以使每个模拟电桥输出端的信号的相位的集合相同，使得最终所有射频通道对应的天线阵列合成的波束的垂直指向与关闭射频通道之前，所述天线阵列合成的波束的垂直指向相同，从而关闭射频通道前后不改变小区。
当电桥单元103只有1个模拟电桥时，射频装置101可以不包括相位校正单元20，所述1个模拟电桥的1个或者多个输出端具有移相器，以使所述1个模拟电桥输出的多路信号形成预设的相位差。
图6是一种实施方式中的系统10的示意图。
图6中的系统10采用了上述图4或者图5中的模拟电桥的设计，当系统10容量需求较大时，需要开启所有射频通道，使所有射频通道与天线阵列形成一一对应的关系，从而能够发送或者接收较多的信息。由于模拟电桥的性能，从模拟电桥的一个输入端输入的信号会分成至少两路分别从模拟电桥的输出端输出，无法与天线阵列形成一一对应的关系。图6示出的系统10能够在引入模拟电桥时，使得射频通道与天线阵列仍然保持一一对应。
需要说明的是，本实施方式中，采用4个射频通道，2个两路输入两路输出的模拟电桥以及4个天线阵列的架构作为例子来说明。实际应用中，射频通道的数量，电桥装置中模拟电桥的输入端数量之和，输出端数量之和，以及天线阵列的数量相同即可。射频通道和天线阵列可以为1个或者多个，例如1个，2个，3个或者更多。模拟电桥可以为1个或者多个，例如1个，2个，3个或者更多。本申请实施例对此不做限定。
图6示意出的射频装置101包括两个第一射频通道30，两个第二射频通道50，信号处理单元412，信号处理单元612和相位校正单元20。
图6中示意出的电桥装置103包括第一模拟电桥40和第二模拟电桥60，第一模拟电桥40包括两个第一输入端41和两个第一输出端42，所述两个第一输出端42为第一端口421和第二端口422。第二模拟电桥60包括两个第二输入端61和两个第二输出端62，所述两个第二输出端62为第三端口621的信号和第四端口622；电桥装置103还包括放大器，耦合器，移相器。两个第一输入端41和两个第二输入端61均设有功率放大器411。两个第一输出端42和两个第二输出端62均设置耦合器80。
图6中示意出的天线装置包括两个第一天线阵列71和两个第二天线阵列72。
需要说明的是，图6中示意出的与图4或者图5相同标号的装置或者组件可以实现与图4或者图5中相同或者类似的功能。
本实施方式中，每个模拟电桥都包括两个输入端和两个输出端。四个射频通道分别驱动四个天线阵列，且通过四路独立的信号支路实现一对一的驱动，如图6中带箭头的虚线所标示的方向为信号的流向，包括四条接近平行的虚线。具体地，所述第一射频通道30、所述第一输入端41和所述第一输出端42一一对应连接形成两路并列的第一信号支路。所有的所述第二射频通道50均打开的状态下，所述第二射频通道50、所述第二输入端61和所述第二输出端62一一对应连接形成两路并列的第二信号支路。
当所述两个第一射频通道均打开的状态下，所述信号处理单元对412所有的所述第一射频通道30的信号进行预加权处理，以实现所述两个第一射频通道30的信号分别从所述两路并列的第一信号支路传送至不同的第一天线阵列71。当所述两个第二射频通道50均打开的状态下，所述信号处理单元612对所有的所述第二射频通道50的信号进行预加权处理，以实现所述两个第二射频通道50的信号分别从所述两路并列的第二信号支路传送至不同的第二天线阵列72。信号处理单元412、612可以通过软件来实现，或者可以为硬体电路架构。
一种实施方式中，所述信号处理单元412、612通过反补电桥的方式对所述第一射频通道30和第二射频通道50的信号进行预加权处理，所述信号处理单元412、612的反补电桥分别是第一模拟电桥40和第二模拟电桥60的逆矩阵，举例说明，一种实施方式中，反补电桥的算法如下：
所述第一模拟电桥40的矩阵为：
Figure PCTCN2019073228-appb-000005
其中，j为复数。
反补电桥的信号的矩阵为第一模拟电桥40的逆矩阵，为：
Figure PCTCN2019073228-appb-000006
通过所述反补电桥预加权前的所述第一模拟电桥40输出信号中的一路信号表达为：
Figure PCTCN2019073228-appb-000007
通过所述反补电桥预加权后的所述第一射频通道30的输入信号，即对应上述第一模拟
电桥40的一路输出信号的输入信号为：
Figure PCTCN2019073228-appb-000008
可见，通过反补电桥预加权后，每一个信号支路中的射频通道输入的信号与模拟电桥输出的信号是一致的，实现了每一路信号支路的输入端和输出端的信号的一致性。
需要说明的是，实现中，第一模拟电桥40和第二模拟电桥60的矩阵可以有除了上述举例中的其他形式，本申请实施例对此不作限定。
相位校正单元20可以参考第一端口421和第三端口621耦合回的信号，或者相位校正单元20也可以参考第二端口422和第四端口622耦合回的信号。第一、第二、第三、第四端口均可以连接至相位校正单元20，相位校正单元20参考第一、第二、第三、第四端口信号的相位对输入两个第一射频通道30的信号和输入两个第二射频通道50的信号做调节，并将调整后的信号发送至对应的射频通道(指两个第一射频通道30和两个第二射频通道50)，调整后，第一、第二、第三、第四端口输出的信号的相位对齐。本实施方式中，相位校正单元20可以参考第一、第二、第三、第四端口的所有信号对输入射频通道的信号进行相位调节，使得这四个端口的信号的相位对齐一个统一的相位值。也可以只参考第一、第二、第三、第四端口其中三个端口的信号对输入射频通道的信号进行相位调节，使所参考的三个端口的信号的相位以另一个端口的相位值为基准进行对齐。
相位校正单元20对信号进行校正的细节与图4所示的实施方式可以是一致的，不再赘述。
图7是本申请另一实施例提供系统10的示意图。
本实施方式与图6所示的实施方式的区别在于，本实施方式中，通信装置关闭了两个射频通道，即第一射频通道30和第二射频通道50的数量均为一个，相应地，第一模拟电桥40的第一输入端41和第二模拟电桥60的第二输入端61的数量也均为一个，但是第一模拟电桥40和第二模拟电桥60的输出端并未关闭，即仍然具有两个第一输出端42和两个第二输出端62，天线阵列也未关闭，即仍然具有两个第一天线阵列711和两个第二天线阵列72。本实施方式实现了一路输入信号驱动两路天线阵列，如图7中带箭头的虚线所标示的方向为信号的流向。关闭了两个射频通道，可以起到节能的作用，但是本实施方式中，依然使用四个天线阵列(两个第一天线阵列711和两个第二天线阵列72)完成信号的发射，天线系统的覆盖性能并未明显降低。
本实施方式通过第一模拟电桥40和第二模拟电桥60的设置，使得第一射频通道30和第二射频通道50的信号分别经过第一模拟电桥40和第二模拟电桥60后，被分为两个第一分信号和两个第二分信号，并利用相位校正单元20对信号的相位调整，使得两个第一分信号分别驱动两个第一天线阵列71，两个第二分信号分别驱动两个第二天线阵列72，这样一个射频通道的信号可以分解为至少两路信号并能够发送至至少两个天线阵列。可以实现 用较少的射频通道驱动较多的驱动天线阵列，降低系统10的功耗，实现节能。
本实施方式中，两个第一输出端42和两个第二输出端62均设置耦合器80，即通信装置包括4个耦合器80，两个第一输出端42和两个第二输出端62输出的信号均通过耦合器80后再输送至第一天线阵列71和第二天线阵列72。通信装置还包括两个移相器90，分别设置在其中一个第一输出端42和其中一个第二输出端62。移相器90的设置用于改变信号的相位，使得两个第一输出端42处的信号的相位差为第一预设值，及使得两个第二输出端62处的信号的相位差为第二预设值。第一预设值和第二预设值可以相等。
图6和图7以2输入2输出的模拟电桥为例，实现中该模拟电桥可以N路输入，M路输出，M大于等于N；该模拟电桥可以是单个电桥或者模拟电桥组，下面示意出了一种模拟电桥组的结构。
请参阅图8，模拟电桥组103包括四个电桥，分别为第一电桥40a、第二电桥40b、第二电桥60a和第四电桥60b，从第一电桥40a的一个输入端41输入的信号i0进入第一电桥40a后，分为两路信号i1和i2。其中第一路信号i1从第一电桥40a输出并从第二电桥40b的输入端进入第二电桥40b。第一路信号i1在第二电桥40b内分别两路信号i3和i4，因此，第二电桥40b的第一输出端421输出信号i3，第二电桥40b的第二输出端422输出信号i4。其中第二路信号i2从第一电桥40a输出并从第四电桥60b的输入端进入第四电桥60b。第二路信号i2在第四电桥60b内分别两路信号i5和i6，因此，第四电桥60b的第一输出端621输出信号i5，第四电桥60b的第二输出端622输出信号i6。这样，一个信号i0从模拟电桥组103输入，可以分解为四个输出信号i3、i4、i5、i6。
结合上述图4至图8中任一幅图的描述，本申请实施例提供了以下通信装置：
本申请实施例提供了一种通信装置，该通信装置包括射频装置101和电桥单元103。该通信装置可以是RRU、RFU或者其他具备能够完成数字信号或者中频信号与射频信号之间的转换的装置。
