Abstract

本申请实施例公开了一种通信装置。该通信装置可以包括第一收发信机、第二收发信机以及功率放大器，其中，第一收发信机和第二收发信机可以分别与功率放大器连接。这样，当确定网络负载较低时，可以关闭该通信装置中的任意一个收发信机。由于该被关闭的收发信机不再继续产生功耗，也就降低了该通信装置整体的功耗，达到节能的效果。而且，在关闭通信装置中的电子器件时，可以不关闭功率放大器，该功率放大器依然可以从未关闭的收发信机中接收到相应的射频信号进行功率放大以及相应的射频信号发送，这使得系统的信道容量基本保持不变，并且天线增益并没有得到降低，从而使得网络信号的覆盖范围也没有发生降低。

Description

一种通信装置
本申请要求于2019年9月30日提交中国国家知识产权局、申请号为201910944620.3、发明名称为“一种通信装置”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
本申请涉及通信技术领域，尤其是涉及一种通信装置。
背景技术
随着长期演进(long term evolution，LTE)、第五代移动通信技术(5th generation mobile networks，5G)移动通信网络的不断发展，多天线技术，例如多输入多输出(multiple-input multiple-output，MIMO)技术逐渐成为移动通信的核心技术，并被运营商进行重点部署。其中，多天线技术，是指在发射端和接收端分别使用多个发射天线和/或多个接收天线，并利用发射端的多个天线进行信号发送和/或利用接收端的多个天线进行信号接收。这不仅可以改善信号的通信质量，而且，通过多个天线收发信号，可以在不增加频谱资源和天线发射功率的情况下，成倍的提高系统信道容量。
但是，多天线技术在改善信号的通信质量以及提高系统信道容量的同时，也给运营商带来了功耗较高的问题，因此，在应用多天线技术时降低系统功耗是非常有必要的。
发明内容
为了解决上述问题，本申请实施例提供了一种通信装置，以使得在应用多天线技术时可以基于该通信装置降低系统功耗，实现节能。
第一方面，本申请实施例提供了一种通信装置，该通信装置可以包括第一收发信机、第二收发信机以及第一功率放大器；其中，该第一收发信机与第二收发信机可以分别与该第一功率放大器连接。在该实施方式中，在利用该通信装置实现多天线技术的应用时，若系统当前的网络负载较低，需要对系统进行节能，则可以关闭该通信装置中的第一收发信机或者第二收发信机，由于关闭了该通信装置中的其中一个收发信机，该被关闭的收发信机不再继续产生功耗，也就降低了该通信装置整体的功耗，从而在应用多天线技术时可以降低系统的功耗，达到节能的效果；同时，该通信装置中的其中一个收发信机关闭后，第一功率放大器依然可以从未关闭的收发信机中接收到相应的射频信号进行功率放大以及相应的射频信号发送，这使得系统的信道容量基本保持不变，并且天线增益并没有得到降低，从而使得网络信号的覆盖范围也没有发生降低。
在一种可能的实施方式中，该通信装置还可以包括第二功率放大器，其中，第一收发信机与第二收发信机可以分别与第二功率放大器连接。在该实施方式中，对于通信装置中的每个功率放大器，均可以与多个收发信机连接，比如，当通信装置还包括第二功率放大器时，该第二功率放大器还可以与第一收发信机与第二收发信机连接。这样，与第一功率 放大器类似，当与第二功率放大器连接的第一收发信机或者第二收发信机关闭时，第二功率放大器依然可以接收到来自未关闭的收发信机的射频信号，从而在通过收发信机实现系统节能时，系统的信道容量可以基本保持不变，并且网络信号的覆盖范围也没有发生降低。
在进一步可能的实施方式中，通信装置还包括第一电桥；其中，该第一收发信机与第一电桥的第一端口连接；所述第二收发信机与所述第一电桥的第二端口连接；所述第一电桥的第三端口与所述第一功率放大器连接；所述第一电桥的第四端口与所述第二功率放大器连接；所述第一电桥的第一端口分别与所述第一电桥的第三端口以及所述第一电桥的第四端口连接，所述第一电桥的第二端口分别与所述第一电桥的第三端口以及所述第一电桥的第四端口连接。在该实施方式中，通信装置可以包括至少两个功率放大器，并且，每个收发信机均可以通过电桥与两个功率放大器之间进行连接。这样，当关闭通信装置中的任一个收发信机，剩余收发信机也可以通过两个功率放大器实现信号输出，从而在实现系统节能的同时，也能使得系统的信道容量以及网络信号的覆盖范围没有得到降低。
在一种可能的实施方式中，所述通信装置还包括第一处理器，所述第一处理器分别与所述第一收发信机和所述第二收发信机连接；所述第一处理器，用于根据第一加权矩阵对第一基带信号和第二基带信号分别进行加权求和处理，得到第三基带信号和第四基带信号，其中，所述第三基带信号输出给所述第一收发信机，所述第四基带信号输出给所述第二收发信机；所述第一加权矩阵为所述第一电桥的电桥矩阵的逆矩阵。在该实施方式中，通过增加第一处理器来对输出给收发信机的基带信号进行加权处理，可以使得收发信机与功率放大器之间具有一一对应的关系，即每个功率放大器所接收到的射频信号可以是一个收发信机所输出的射频信号，而不是多个收发信机所输出的射频信号的混合。
在一些可能的实施方式中，所述通信装置还包括第三收发信机、第四收发信机、第三功率放大器、第四功率放大器、第二电桥、第三电桥和第四电桥；所述第一收发信机与第二电桥的第一端口连接，所述第二电桥的第三端口与所述第一电桥的第一端口连接；所述第二收发信机与所述第三电桥的第一端口连接，所述第三电桥的第三端口与所述第一电桥的第二端口连接；所述第三收发信机与所述第二电桥的第二端口连接，所述第二电桥的第四端口与所述第四电桥的第一端口连接；所述第四收发信机与所述第三电桥的第二端口连接，所述第三电桥的第四端口与所述第四电桥的第二端口连接；所述第四电桥的第三端口与所述第三功率放大器连接，所述第四电桥的第四端口与所述第四功率放大器连接；所述第二电桥的第一端口分别与所述第二电桥的第三端口以及所述第二电桥的第四端口连接，所述第二电桥的第二端口分别与所述第二电桥的第三端口以及所述第二电桥的第四端口连接；所述第三电桥的第一端口分别与所述第三电桥的第三端口以及所述第三电桥的第四端口连接，所述第三电桥的第二端口分别与所述第三电桥的第三端口以及所述第三电桥的第四端口连接；所述第四电桥的第一端口分别与所述第四电桥的第三端口以及所述第四电桥的第四端口连接，所述第四电桥的第二端口分别与所述第四电桥的第三端口以及所述第四电桥的第四端口连接。在该实施方式中，通信装置中的四个收发信机以及四个功率放大器可以通过四个电桥进行连接，并且，基于该四个电桥，每个功率放大器所接收到的射频信号可以是四个收发信机所输出射频信号的混合，即每个功率放大器可以同时与四个收发信 机连接，并接收到四个收发信机所接收到的射频信号。这样，即使其中一个至三个收发信机被关闭以节省系统能耗，每个功率放大器均可以接收到剩余收发信机所发送的射频信号，从而使得系统的信道容量以及网络信号的覆盖范围也没有得到降低。
在一些可能的是实施方式中，所述通信装置还包括第一开关和第二开关；所述第三电桥的第三端口连接所述第一开关的一端，所述第一开关的另一端连接所述第一电桥的第二端口；所述第二电桥的第四端口连接所述第二开关的一端，所述第二开关的另一端连接所述第四电桥的第一端口；当所述第二收发信机和所述第三收发信机关闭时，或，当所述第一收发信机和所述第四收发信机关闭时，所述第一开关和所述第二开关断开。在该实施方式中，可以进一步在电桥之间设置连接开关，以使得当四个收发信机的其中两个收发信机关闭时，每个功率放大器均可以接收到一个收发信机输出的射频信号，并且，其中两个功率放大器所接收到的射频信号为同一个收发信机所输出的射频信号，另两个功率放大器所接收到的射频信号为另一个收发信机所输出的射频信号。实际应用中，当系统需要节能时，可以断开在四个电桥之间所设置的连接开关，并关闭相应的收发信机，以节省系统能耗。
在一些可能的实施方式中，所述通信装置还包括第三开关；所述第二收发信机通过所述第三开关与所述第一功率放大器连接。在该实施方式中，在第二收发信机与第一功率放大器之间可以设置有第三开关，当系统基于节能的需要关闭第一收发信机时，可以将第三开关闭合，这样，第二收发信机可以与第一功率放大器连接，从而可以使得第一功率放大器依然可以接收到第二收发信机所输出的射频信号，以便在实现节能的同时也不会降低系统的信道容量以及网络信号的覆盖范围。
在一些可能的实施方式中，所述通信装置为远端射频单元RRU。
在一些可能的实施方式中，所述通信装置还包括第一组天线，所述第一功率放大器与第一组天线连接。在该实施方式中，通信装置可以利用该第一组天线对第一功率放大器所放大的射频信号进行信号发送，也可以利用该第一组天线接收客户端(如用户设备等)发送的信号，并通过该第一功率放大器对其进行功率放大。

在一些可能的实施方式中，所述第一电桥的第一端口和所述第一电桥的第二端口为输入端；所述第一电桥的第三端口和所述第一电桥的第四端口为输出端。在该实施方式中，当通信装置向客户端发送射频信号时，第一收发信机所输出的射频信号可以通过第一端口输入至第一电桥，并通过第三端口输出值第一功率放大器，以便由第一功率放大器对其进行功率放大后进行信号发送；类似的，第二收发信机可以通过第二端口输入至第一电桥，并通过第四端口输出至第二功率放大器进行功率放大，进而进行信号发送。

在一些可能的实施方式中，所述第一电桥的第一端口、所述第一电桥的第二端口、所述第二电桥的第一端口、所述第二电桥的第二端口、所述第三电桥的第一端口、所述第三电桥的第二端口、所述第四电桥的第一端口、所述第四电桥的第二端口均为输入端；所述第一电桥的第三端口、所述第一电桥的第四端口、所述第二电桥的第三端口、所述第二电桥的第四端口、所述第三电桥的第三端口、所述第三电桥的第四端口、所述第四电桥的第三端口、所述第四电桥的第四端口均为输出端。在该实施方式中，当通信装置向客户端发送射频信号时，各个电桥的第一端口以及第二端口可以作为输入端，收发信机所输出的射频信号可以通过各个电桥的第一端口或者第二端口输出的电桥中，并通过相应电桥的第三端口或者第四端口输出至功率放大器，以便于功率放大器对其进行功率放大后完成信号发 送。

具体实施方式
参阅图1，本申请实施例的技术方案可以适用于图1所示的通信系统。在该通信系统，可以包括基带装置101、射频装置102以及天线装置103。其中，基带装置101与射频装置102相连，射频装置102与天线装置103连接。该通信系统可以是基站。
基带装置101主要用于对通信协议以及通信数据进行处理，以及对整个基站进行控制，执行软件程序，处理软件程序的数据。基带装置101中的芯片可以包括基带处理器和中央处理器，基带处理器主要用于对通信协议以及通信数据进行处理，中央处理器主要用于对整个终端设备进行控制，执行软件程序，处理软件程序的数据。或者，基带装置101中的处理器可以集成基带处理器和中央处理器的功能，本领域技术人员可以理解，基带处理器和中央处理器也可以是各自独立的处理器，通过总线等技术互联。本领域技术人员可以理解，基带装置101可以包括多个基带处理器以适应不同的网络制式，基带装置101可以包括多个中央处理器以增强其处理能力。所述基带处理器也可以表述为基带处理电路或者基带处理芯片。所述中央处理器也可以表述为中央处理电路或者中央处理芯片。对通信协议以及通信数据进行处理的功能可以内置在处理器中，也可以以软件程序的形式存储在存储器中，由处理器执行软件程序以实现基带处理功能。例如，基带装置可以是基带单元(base band unit,BBU)。
射频装置102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103，或者从天线装置103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103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102。
其中，射频装置102可以包括多个射频通道。需要说明的是，这里射频通道可以指射频装置102中的电路通道，该电路通道可以包括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。
逻辑通道也可以称为收发器、收发单元、收发机、收发装置、射频通道、收发信机等。可选的，可以将收发单元中用于实现接收功能的器件视为接收单元，将收发单元中用于实 现发送功能的器件视为发送单元，即收发单元包括接收单元和发送单元，接收单元也可以称为接收机、输入口、接收电路等，发送单元可以称为发射机、发射器或者发射电路等。射频装置102和天线装置103物理上可以分开。例如，射频装置102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103可以是多根天线，该多根天线可以布局在一副天线罩内。当然，射频装置102和天线装置103物理上也可以集成在一起。例如，系统可以是有源天线单元(Active Antenna Unit，AAU)。
天线装置103可以包括多个天线阵列。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。每个天线阵列可以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。
需要说明的是，上述介绍中，将基带装置可以处理的信号称为基带信号，实现中可能是数字基带信号或者数字中频信号，或者是其他信号，本申请实施例对此不做限定，将射频装置处理得到的信号或者从天线接收的信号称为射频信号，随着无线通信技术的发展，射频装置处理得到的信号或者从天线接收到的信号可能是其他信号，本申请实施例对此不作限定。
实际应用中，可以采用多天线技术(如MIMO技术)实现上述通信系统。其中，多天线技术可以支持多用户配对，即在同一块时频资源上可以支持多个用户同时进行数据流传输。以应用MIMO技术为例，射频模块可以包括多个收发信机(transceiver，简称TRX)，相应的，每个TRX与功率放大器(power amplifier，PA)之间进行一对一连接，如TRX1与PA1一对一连接等。假设当前需要发送信号，数据流在经过TRX的中射频处理后，可以输入至PA中进行功率放大，再依次传输至带通滤波器以及天线装置，使得数据流被传输至MIMO客户端。其中，射频模块所包含的TRX数目决定了网络的配对能力。通常情况下，射频模块的TRX数目越多，网络配对的能力越强，也即可以同时支持更多的用户使用相同的时频资源来传输数据流。
但是，多个TRX与PA在运行时所产生的功耗通常较高，尤其是当网络负载较低时，网络的实际配对用户较少，但仍然会使用所有的TRX以及PA，即所有的TRX以及PA均处于高功耗的运行状态，这就产生了不必要的功耗浪费。
为此，本申请实施例提供了一种通信装置，以使得在应用多天线技术时可以基于该通信装置降低系统功耗，达到节能效果。具体的，如所示，该通信装置可以应用于图1所示的通信系统中，该通信装置可以包括第一收发信机11、第二收发信机12以及第一功率放大器13，其中，第一收发信机11和第二收发信机12可以分别与第一功率放大器13连接。
本申请实施例中的连接，可以理解为直接连接(即中间可以没有其它元器件实现连接)，也可以是间接连接(即中间可以是通过其它元器件实现连接，如电桥、开关等)。值得注意的是，当收发信机与功率放大器之间的开关没有闭合的时候，也可以是认为收发信机与功率放大器连接。
另外，收发信机与功率放大器连接，还可以理解为，基带信号在经过收发信机的射频处理后，所得到的射频信号可以传输至功率放大器。需要说明的是，第一收发信机11和第二收发信机12可以分别与第一功率放大器13连接，信号可以同时通过第一收发信机11与第二收发信机12传输至功率放大器，也可以是不同时传输至功率放大器。例如，T1时刻，第一信号可以通过第一收发信机11传输至第一功率放大器13，T2时刻(不等于T1时刻)，第二信号可以通过第二收发信机12传输至第一功率放大器13；或者，第一信号在通过第一收发信机11传输至第一功率放大器13的同时，第二信号也通过第二收发信机12传输至第一功率放大器13。
这样，当确定网络负载较低时，多余的收发信机可以结束运行，因此可以关闭该通信装置中的任意一个收发信机，如可以关闭第一收发信机11或者第二收发信机12。可以理解，在基于该通信装置实现多天线技术的应用过程中，由于关闭了该通信装置中的其中一个收发信机，该被关闭的收发信机不再继续产生功耗，也就降低了该通信装置整体的功耗，从而在应用多天线技术时可以降低系统的功耗，达到节能的效果。而且，在关闭通信装置中的电子器件时，是对与功率放大器相连的其中一个收发信机进行关闭，而可以不关闭功率放大器，该功率放大器依然可以从未关闭的收发信机中接收到相应的射频信号进行功率放大以及相应的射频信号发送，这使得系统的信道容量基本保持不变，并且天线增益并没有得到降低，从而使得网络信号的覆盖范围也没有发生降低。
可选的，当上述通信装置应用于图1所示的通信系统中时，如图3所示，射频装置102可以包括第一收发信机11、第二收发信机12，天线装置103可以包括功率放大器13、带通滤波器14(当然，在其它实施方式中，也可以不包括带通滤波器14以及天线15)。其中，第一收发信机11与第二收发信机12分别与功率放大器连接13，功率放大器13与带通滤波器14连接，带通滤波器14与天线15连接。在一些可能的实施方式中，第一收发信机11可以包括电连接的调制器111、上变频器112、振荡器113、下变频器114和解调制器115。其中，调制器111和解调制器115连接一个振荡器113，上变频器112和下变频器114连接一个振荡器113，需要说明的是，这仅仅是一个示例，调制器111和解调制器115可以连接不同的振荡器，上变频器112和下变频器114可以连接不同的振荡器，本申请实施例对此不作限定。基带控制单元发送的基带信号进入第一收发信机11后，依次经过调制器111、上变频器112、功率放大器13和带通滤波器14后，发送给天线装置103。相应的，天线信号从天线装置103依次经过带通滤波器14、功率放大器13、下变频器114和解调制器115后形成基带信号发送给基带控制单元。类似的，第二收发信机12可以包括电连接的调制器121、上变频器122、振荡器123、下变频器124和解调制器125。其中，调制器121和解调制器125连接一个振荡器123，上变频器112和下变频器114连接一个振荡器123。需要说明的是，图3仅仅作为一种示例进行说明，实际应用中，射频装置102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。
对于图1所示的通信系统，若确定当前网络负载较小，则可以关闭系统中的第一收发信机11(当然，也可以是关闭系统中的第二收发信机12，此处以关闭第一收发信机11为例进行说明)，使得系统中第一收发信机11结束运行，而第二收发信机12继续运行并与功率放大器13协同完成射频信号的发送与接收。由于该系统中的第一收发信机11结束运行，该第一收发信机11可以停止产生能耗，从而也就降低了系统的功耗，达到了节能的效果。同时，该系统中的功率放大器13并没有关闭，依然可以从第二收发信机12中接收到数据流进行相应的功率放大以及信号发送，因此，系统的信道容量基本保持不变，并且天线增益并没有得到降低，从而在实现降低系统的功耗的同时，也没有降低网络信号的覆盖范围以及系统的信道容量。
下面具体对本申请中的技术方案进行详细介绍。
如图4所示，为本申请实施例所提供的通信装置。该通信装置所包括的第一收发信机11和第二收发信机12在分别与第一功率放大器13连接的同时，还可以分别与第二功率放大器43连接。其中，图4所示的收发信机以及功率放大器可以与图2所示的收发信机以及功率放大器具有相同或者相似的功能。数据流1在经过第一收发信机11的中射频处理后，可以分别进入第一功率放大器13以及第二功率放大器43中进行功率放大，并经过与第一功率放大器13连接的天线1传输至第一客户端(如传输至用户设备等)，经过与第二功率放大器43连接的天线2传输至第二客户端；类似的，数据流2在经过第二收发信机12的中射频处理后，同样可以分别接入第一功率放大器13以及第二功率放大器43中进行功率放大，并分别经过与第一功率放大器13连接的天线1传输至第一客户端，经过与第一功率放大器43连接的天线2传输至第二客户端。进一步的，该第一功率放大器13还可以与第一组天线(图4中未示出)连接，该第一组天线包括第一发射天线以及第一接收天线；该第二功率放大器43还可以与第二组天线(图4中未示出)连接，该第二组天线包括第二发射天线以及第二接收天线。
值得注意的是，基于图4所示的通信装置，天线1或者天线2所发送的射频信号为多路数据流对应的混合射频信号，比如，天线1向第一客户端发送的射频信号，为集成数据流1以及数据流2所得到的混合射频信号，则，第一客户端或者第二客户端在接收到该混合射频信号后，可以对该混合射频信号进行相应解调，分别得到数据流1对应的信号以及数据流2对应的信号。
这样，当确定网络负载较低时，比如，当前仅有第一客户端存在与系统的通信需求时，可以关闭第二客户端对应的第二收发信机12。可以理解，在关闭第二收发信机12后，该第二收发信机12不再产生功耗，相应的，系统的功耗可以得以降低；同时，第一功率放大器13与第二功率放大器43仍然继续运行，从而没有降低系统的网络信号覆盖范围以及系统的信道容量。
进一步的，第一收发信机11以及第二收发信机12可以通过电桥分别与第一功率放大器13以及第二功率放大器43进行连接，如图5所示。具体的，第一收发信机11可以与第 一电桥50的第一端口51连接，第二收发信机12可以与第一电桥50的第二端口52连接，该第一电桥50的第三端口53可以与第一功率放大器13连接，第一电桥50的第四端口54可以与第二功率放大器43连接，并且，该第一电桥50的第一端口51可以分别与第一电桥50的第三端口53以及第四端口54连接，第一电桥50的第二端口52可以分别与第一电桥50的第三端口53以及第四端口54连接。
当第一收发信机11以及第二收发信机12运行时，若系统当前向用户设备(客户端)发送通信数据，则第一收发信机11所接收到的数据流可以通过第一电桥50的第一端口51进入电桥，并分别从第三端口53流入第一功率放大器13，以及从第四端口54流入第二功率放大器43；类似的，第二收发信机12所接收到的数据流可以通过第一电桥50的第二端口52进入电桥，并分别从第三端口53流入第一功率放大器13，以及从第四端口54流入第二功率放大器43。此时，第一电桥50的第一端口51以及第二端口52为输入端，第一电桥50的第三端口53以及第四端口54为输出端。
而若系统当前为接收用户设备发送的通信数据，则第一功率放大器13所接收到的数据流可以第一电桥50的第三端口53流入第一电桥50，并从第一端口51流入第一收发信机11，从第二端口52流入第二收发信机12；类似的，第二功率放大器43所接收到的数据流可以第一电桥50的第四端口54流入第一电桥50，并从第一端口51流入第一收发信机11，从第二端口52流入第二收发信机12。此时，第一电桥50的第一端口51以及第二端口52为输出端，第一电桥50的第三端口53以及第四端口54为输入端。
而当系统确定当前网络负载较低或者系统被通知当前网络负载较低时，可以关闭第一收发信机11或者第二收发信机12。其中，对于具体判决关闭哪个收发信机，可以根据收发信机与用户设备(客户端)之间的配对情况进行确定。比如，若第一收发信机11当前不存在与其配对的用户设备，则可以关闭第一收发信机11，而第二收发信机12可以继续为与其配对的用户设备进行数据处理和传输。这样，在关闭第一收发信机11实现节能的同时，由于第一功率放大器13以及第二功率放大器43并未关闭，因此，系统的信道容量以及网络信号覆盖范围并没有得到降低。
图2以及图5所示的通信装置中，是以包含2个收发信机为了进行示例性说明。实际应用中，该通信装置所包含的收发信机可以N个，N为大于等于1的整数，例如N是64，则，在实现对系统进行节能时，可以通过上述过程，以两个收发信机为单位，关闭64个收发信机中的32个收发信机，而对于剩余的32个收发信机中的每个收发信机，均可以与两个功率放大器进行连接，从而实现系统的节能。当然，所关闭的收发信机不限于32个，比如，也可以是关闭其中的16个、20个收发信机等，其中，在不降低系统信道容量以及网络信号的覆盖范围的情况下，对于包含64个收发信机的系统，其所关闭的收发信机的数量不大于32。
实际应用中，若多个收发信机与同一个功率放大器之间通过电桥进行连接，则在系统向用户设备发送通信数据时，每个功率放大器所接收到的信号混合了多个收发信机所输出信号，比如，当第一收发信机11与第二收发信机同时运行时，第一收发信机11以及第二收发信机12所输出的射频信号均传输至功率放大器13，使得功率放大器所接收到的射频 信号为多个收发信机输出射频信号进行混合所得到的射频信号。为此，本实施例中，还可以为发送给收发信机基站信号进行一定的加权求和处理，以使得收发信机与功率放大器之间建立一一对应的关系。具体的，在图5所示的通信装置的基础上还可以进一步增加第一处理器10，得到如图6所示的系统。在该系统中，第一处理器10可以分别与第一收发信机11以及第二收发信机12连接。其中，第一处理器10，可以利用第一加权矩阵对要传输至第一收发信机11的第一基带信号进行加权求和处理，得到相应的第三基带信号，并利用该第一加权矩阵对要传输至第二收发信机12的第二基带信号进行加权求和处理，得到第四基带信号，而该第一加权矩阵为第一电桥50的电桥矩阵的逆矩阵。然后，第三基带信号输出给第一收发信机11，而第四基带信号输出给第二收发信机12。
例如，第一加权矩阵具体可以是：
Figure PCTCN2020103072-appb-000001
其中，j为复数。
第一电桥50的电桥矩阵为该第一加权矩阵的逆矩阵，为：
Figure PCTCN2020103072-appb-000002
以X0表征第一基带信号，X1表征第二基带信号，Y0和Y1分别表征第一电桥50输出的两路不同射频信号，则：
Figure PCTCN2020103072-appb-000003
可见，通过第一处理器对第一基带信号以及第二基带信号进行加权求和处理后，每个功率放大器所接收到的信号为单个收发信机所输出的射频信号，而可以不是多个射频信号的混合，从而实现了每一路信号的输入以及输出信号的一致性。
类似的，当系统接收用户设备发送的信号时，还可以利用处理器(为便于与第一处理器10区分，以下称之为第四处理器)对收发信机输出的信号进行加权求和处理。具体的，系统可以包括第四处理器，该第四处理器同样分别与第一收发信机11以及第二收发信机12连接，并且，可以利用第四加权矩阵对第一收发信机11输出的第一基带信号进行加权求和处理，得到相应的第三基带信号，并利用该第四加权矩阵对第二收发信机12输出的第二基带信号进行加权求和处理，得到相应的第四基带信号，该第四加权矩阵为该第一电桥50的电桥矩阵的逆矩阵。实际应用中，上述第一处理器10与第四处理器可以是同一处理器。
可选的，在本申请实施例中，处理器可以与存储器耦合，执行存储器中的程序或者指令，完成加权求和的处理，或者存储器可以存储加权矩阵的信息，处理器可以读取存储器中存储的加权矩阵的信息，完成加权求和的处理。在一些可能的实施方式，上述第一处理器具体可以在基带处理单元(Building Base band Unite，BBU)中，而集成该BBU的系统可以是基站等，可选的，BBU中还包括存储器。或者第一处理器可以位于射频装置102中，可选的，射频装置102中还包括存储器。
对于包含64个收发信机的系统，采用上述实施方式，可以将系统由64收发信机运行的状态切换至32个收发信机运行的状态。但是，在另一些可能的实施方式中，还可以进一步将系统由64个收发信机运行的状态切换至16个收发信机运行的状态。具体的，下面以系统包括4个收发信机为例进行举例说明，参阅图5所示的系统。
图7所示的通信装置中，包括4个收发信机，分别为第一收发信机11、第二收发信机12、第三收发信机23、第四收发信机24，还包括4个功率放大器，分别为第一功率放大器13、第二功率放大器43、第三功率放大器130以及第四功率放大器430，还包括4电桥，分别为电桥50、电桥60、电桥70以及电桥80。其中，如图7所示，各个电子器件的相互之间的连接关系为：第一收发信机11与第二电桥60的第一端口61连接，第二电桥60的第三端口63与第一电桥50的第一端口51连接；第二收发信机12与第三电桥70的第一端口71连接，第三电桥70的第三端口73与第一电桥50的第二端口52连接；第三收发信机23与第二电桥60的第二端口62连接，第二电桥60的第四端口64与第四电桥80的第一端口81连接；第四收发信机24与第三电桥70的第二端口72连接，第三电桥70的第四端口74与第四电桥80的第二端口82连接；第四电桥80的第三端口83与第三功率放大器23连接，第四电桥80的第四端口84与第四功率放大器24连接；第二电桥60的第一端口61分别与第二电桥60的第三端口63以及第二电桥60的第四端口64连接，第二电桥60的第二端口62分别与第二电桥60的第三端口63以及第二电桥60的第四端口64连接；第三电桥70的第一端口71分别与第三电桥70的第三端口73以及第三电桥70的第四端口74连接，第三电桥70的第二端口72分别与第三电桥70的第三端口73以及第三电桥70的第四端口74连接；第四电桥80的第一端口81分别与第四电桥80的第三端口83以及第四电桥80的第四端口84连接，第四电桥80的第二端口82分别与第四电桥80的第三端口83以及第四电桥80的第四端口84连接。
进一步的，该第一功率放大器13还可以与第一组天线(图7中未示出)连接该第一组天线包括第一发射天线以及第一接收天线；该第二功率放大器43还可以与第二组天线(图7中未示出)连接该第二组天线包括第二发射天线以及第二接收天线；该第三功率放大器130还可以与第三组天线(图7中未示出)连接该第三组天线包括第三发射天线以及第三接收天线；该第四功率放大器430还可以与第四组天线(图7中未示出)连接该第四组天线包括第四发射天线以及第四接收天线。
当系统中的各个收发信机均处于运行状态时，若系统当前向用户设备发送通信数据，以第三收发信机23为例(其它收发信机类似)，第三收发信机23接收到的数据流可以通过第二电桥60的第二端口62流入第二电桥60，由于第二端口62分别与第三端口63和第四 端口64连接，因此，数据流可以从第二端口分别达到第三端口63以及第四端口64；然后，第三端口63与第一电桥50的第一端口51连接，而第一端口51分别与第三端口53以及第四端口54连接，因此，第三端口63处的数据流可以依次经过第一端口51、第三端口53流入第一功率放大器11，经过第一端口51、第三端口53流入第二功率放大器12，并且，第三端口63与第四电桥80的第一端口81连接，而第一端口81分别与第三端口83以及第四端口84连接，因此，第三端口63处的数据流还可以依次经过第一端口81、第三端口83流入第三功率放大器23，经过第一端口81、第四端口84流入第四功率放大器24。即，每个收发信机所接收到的数据流最终都可以分别流入这4个功率放大器，相应的，每个功率放大器所接收到的数据流也即为集成这四个收发信机所接收到的数据流所得到的混合数据流。
此时，第一端口51、第二端口52、第一端口61、第二端口62、第一端口71、第二端口72、第一端口81以及第二端口82均为数据流的输入端，而第三端口53、第四端口54、第三端口63、第四端口64、第三端口73、第四端口74、第三端口83以及第四端口84均为数据流的输出端。
反之，若系统当前接收用户设备发送通信数据时，仍以第一功率放大器13接收到用户设备的通信数据为例(其它功率放大器类似)，第一功率放大器13可以将数据流通过第一电桥50的第三端口53流入第一电桥，并依次经过第一端口51、第三端口63以及第一端口61流入第一收发信机11，经过第一端口51、第三端口63以及第二端口62流入第三收发信机23，经过第二端口52、第三端口73以及第一端口71流入第二收发信机12，经过第二端口52、第三端口73以及第二端口72流入第四收发信机24。
此时，第一端口51、第二端口52、第一端口61、第二端口62、第一端口71、第二端口72、第一端口81以及第二端口82均为数据流的输出端，而第三端口53、第四端口54、第三端口63、第四端口64、第三端口73、第四端口74、第三端口83以及第四端口84均为数据流的输入端。
这样，当系统确定网络负载较低或者系统被通知网络负载较低时，可以关闭当前不存在用户设备与之配对的收发信机，比如，假设当前只有第一收发信机11存在用户设备与之配对，则可以关闭第二收发信机12、第三收发信机23以及第四收发信机24。值得注意的是，系统在因第二收发信机12、第三收发信机23以及第四收发信机24被关闭而实现节能的同时，由于第一收发信机11所接收到的数据流可以分别流入四个功率放大器，从而经由各个功率放大器以及相应的天线装置发送出去，这使得系统的信道容量以及网路信号的覆盖范围并没有得到降低。
实际应用中，若系统中包含64个收发信机，则可以采用上述实施方式，关闭64个收发信机中的48个收发信机，将系统由64收发信机运行的状态切换至16个收发信机运行的状态。当然，系统所关闭的收发信机的数量也可以根据实际应用的需要自行判决，比如，也可以是仅仅关闭20个、32个收发信机等。其中，在不降低系统信道容量以及网络信号的覆盖范围的情况下，对于包含64个收发信机的系统，其所关闭的收发信机的数量不大于48。
在一些可能的实施方式中，当图7所示的系统，在实现不降低系统信道容量以及网络信号的覆盖范围的情况下，关闭部分收发信机时，其可以进一步采用图8所示的结构。如图8所示，该系统还可以进一步包括第一开关S1以及第二开关S2。其中，第三电桥70的第三端口73连接第一开关S1的一端，该第一开关S1的另一端与第一电桥50的第二端口连接；同时，第二电桥60的第四端口64连接第二开关S2的一端，该第二开关S2的另一端可以连接第四电桥80的第一端口81，如图7所示。这样，当关闭图8中的第一收发信机11以及第四收发信机24时，可以断开该第一开关S1以及第二开关S2。此时，当系统向用户设备发送通信数据时，第二收发信机12所接收到的数据流可以依次经过第二电桥60的第二端口62、第三端口63、第一端口51以及第三端口53，流入至第一功率放大器13中进行功率放大以及后续的射频信号发送，同时，也依次经过第二电桥60的第二端口62、第三端口63、第一端口51以及第四端口54，流入至第二功率放大器43中进行功率放大以及后续的射频信号发送。即，未关闭的收发信机所接收到的数据流可以分别流入两个功率放大器中进行功率放大以及信号输出。其中，与第二收发信机12类似，第三收发信机23所接收到的数据流可以分别流入第三功率放大器130和第四功率放大器430。值得注意的是，即使关闭第一收发信机11以及第四收发信机24，图8所示的系统中的各个功率放大器仍然继续运行，因此，并没有降低系统的信道容量以及网络信号的覆盖范围。
当然，对于图8所示的系统，当需要关闭收发信机时，也可以是关闭第二收发信机12以及第三收发信机23，并可以断开第一开关S1以及第二开关S2，其与关闭第一收发信机11以及第四收发信机24类似，在此不做赘述。
进一步的，与图6所示的包含第一处理器10的通信装置类似，对于图7或者图8所示的通信装置，在其基础上还可以增加第二处理器20，以使得各路信号的输入和输出的相位一致。具体的，在一种可能的实施方式中，包括第二处理器20的通信装置可以如图9所示。在图9所示的通信装置中，第二处理器20可以分别与第一收发信机11、第二收发信机12、第三收发信机23以及第四收发信机24连接。当系统需要向用户设备发送通信数据时，第二处理器20，可以利用第二加权矩阵对需要传输至第一收发信机11的第一基带信号进行加权求和处理，得到相应的第五基带信号，并且，所得到的第五基带信号输出给第一收发信机11；利用第二加权矩阵对需要传输至第二收发信机12的第二基带信号进行加权求和处理，得到相应的第六基带信号，并且，所得到的第六基带信号输出给第二收发信机12；利用第二加权矩阵对需要传输至第三收发信机23的第三基带信号进行加权求和处理，得到相应的第七基带信号，并且，所得到的第七基带信号输出给第三收发信机23；利用第二加权矩阵对需要传输至第四收发信机24的第四基带信号进行加权求和处理，得到相应的第八基带信号，并且，所得到的第八基带信号输出给第四收发信机24。其中，上述第二加权矩阵为第三加权矩阵的逆矩阵，而第三加权矩阵为根据第一电桥50的电桥矩阵、第二电桥60的电桥矩阵、第三电桥70的电桥矩阵、第四电桥80的电桥矩阵以及各个电桥之间的连接关系进行确定所得到的组合电桥矩阵。
举例来说，第一电桥50、第二电桥60、第三电桥70以及第四电桥80的电桥矩阵依次为：
Figure PCTCN2020103072-appb-000004
以及
Figure PCTCN2020103072-appb-000005
则，根据这四个电桥的电桥矩阵以及各个电桥之间的连接所确定出的组合电桥矩阵(即为上述第三加权矩阵)可以为：
Figure PCTCN2020103072-appb-000006
而第二加权矩阵即为该第三加权矩阵的逆矩阵。
本实施例中，通过第二处理器对第一基带信号至第四基带信号进行加权求和处理后，每个功率放大器所接收到的信号为单个收发信机所输出的射频信号，而可以不是多个射频信号的混合，从而实现了每一路信号的输入以及输出信号的一致性。
类似的，当系统接收用户设备发送的信号时，还可以利用处理器(为便于与第一处理器20区分，以下称之为第五处理器)对收发信机输出的信号进行加权求和处理。具体的，系统可以包括第五处理器，该第五处理器同样分别与第一收发信机11、第二收发信机12、第三收发信机23以及第四收发信机24连接，并且，可以利用第五加权矩阵对第一收发信机11输出的第一基带信号进行加权求和处理，得到相应的第五基带信号，对第二收发信机12输出的第二基带信号进行加权求和处理，得到相应的第六基带信号，对第三收发信机23输出的第三基带信号进行加权求和处理，得到相应的第七基带信号，对第四收发信机24输出的第四基带信号进行加权求和处理，得到相应的第八基带信号。上述第五加权矩阵为第六加权矩阵的逆矩阵，而第六加权矩阵为根据第一电桥50的电桥矩阵、第二电桥60的电桥矩阵、第三电桥70的电桥矩阵、第四电桥80的电桥矩阵以及各个电桥之间的连接关系进行确定所得到的组合电桥矩阵。
图5至图9所示的系统中，收发信机与功率放大器之间是通过电桥进行连接，而在另一些可能的实施方式中，收发信机与功率放大器之间也可以是采用开关进行连接。具体的，在一种示例中，第一收发信机11可以与第一功率放大器13连接，而第二收发信机12可以通过第三开关与该第一功率放大器13连接。这样，当需要关闭第二收发信机12以实现系统节能时，可以闭合该第三开关，使得第二收发信机12与第一功率放大器13连接。这样，第二收发信机12所接收到的数据流可以流入至第一功率放大器13中，使得第一功率放大器13可以继续运行并完成该路的信号发送，从而使得系统的信道容量以及网络信号覆盖范围未得到降低。
为了便于理解，下面对于收发信机与功率放大器之间采用开关连接的具体实现过程进行举例说明。如图10所示的通信装置(以系统发送数据为例)，该通信装置中所包括的收发信机以及功率放大器与图4至图9所示的通信装置中的收发信机以及功率放大器具有相同或者相似的功能。其中，第一收发信机11与第一功率放大器13连接，同时，第一收发信机11通过开关S3与第二功率放大器43连接，第二收发信机12与第二功率放大器43连接，第二收发信机12通过开关S4与第一功率放大器13连接。基于如图10所示的结构，通常情况下，当第一收发信机11与第二收发信机12运行时，开关S3以及开关S4可以断开，则第一收发信机11可以仅向第一功率放大器13发送射频信号，而第二收发信机12可 以仅向第二功率放大器43发送射频信号；当需要降低系统的功耗时，可以关闭第一收发信机11，并闭合开关S4，这样第二收发信机12可以同时与第一功率放大器13以及第二功率放大器43连接，以实现系统节能的同时，系统的信道容量以及网络信号的覆盖范围也没有得到降低。同理，当关闭第二收发信机12时，可以闭合开关S3，这样第一收发信机11可以同时与第一功率放大器13以及第二功率放大器43连接。
