Description

一种降低PA的功耗的方法及设备 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种降低PA的功耗的方法及设备。
背景技术
通信设备的射频模块中包含有功率放大器(Power Amplifier，PA)，该PA具有对信号的功率进行放大的特性。
目前，为了保证PA的线性，一般会将PA偏置在一个较宽的工作区域；而这种状态下PA的静态功耗会很高，其自身功耗在通信设备功耗中所占的比重较大；并且通信设备中，除PA外的其余模块大多为高集成度的射频集成电路，其功耗受功能及性能的设计约束可调整优化的空间不大；因此为满足节能减排目标及提升产品竞争力，可以在保证产品性能的前提下，降低射频模块中的PA的功耗，从而达到降低通信设备功耗的目的。
现有技术中，可以将射频模块中的PA的发射功率区分为大、中、小三个发射功率等级，并按照大、中、小发射功率提供不同的偏置漏流，以根据不同的发射功率适当调整射频模块中的PA的功耗。此外为了保证通信传输系统的可靠性，需要保证PA的性能以及最大发射功率时的峰均比回退，因此PA的漏压需始终保持在最大发射功率的偏置值上。
但是，由于现有技术中，当通信传输系统中的不需要使用最大发射功率时，PA的漏压也要保持在最大值，因此PA的功耗依然很大；并且，由于发射功率等级划分数量有限，且需要考虑射频模块中各器件的批次性的个体差异，因此会造成一定的漏流设计冗余，造成不必要的功耗浪费。
发明内容
本申请提供一种降低PA的功耗的方法及设备，可以针对不同批次的器件，最大限度的降低PA的功耗。
为达到上述目的，本申请采用如下技术方案：
本申请的第一方面，提供一种降低PA的功耗的方法，站点A中包含有PA，本申请的方法可以包括：站点A接收站点B发送的第一链路状态指示，该第一链路状态指示包含站点A到站点B的链路状态的参数；若第一链路状态指示包含的参数大于第一阈值，站点A则调低PA的漏压，以降低PA的功耗。本申请中，站点A可以根据接收的第一链路状态指示调低PA的漏压，以降低PA的功耗。由于第一链路状态指示用于表征链路状态的质量，当第一链路状态指示包含的参数大于第一阈值时，站点A调低PA的漏压，便可以在保证通信系统的可靠性的情况下，进一步的降低PA的功耗；并且，由于站 点A可以实时监控通信系统的链路状态，因此站点A可以在保证通信系统的可靠性的情况下，在不同的发射功率下针对不同批次的器件，通过实时监控的链路状态最大限度的调低PA的漏压，实现最大限度的降低PA的功耗。
结合第一方面，在本申请的一种可能的实现方式中，第一链路状态指示包括均方误差(Mean Square Error，MSE)、矢量幅度误差(Error Vector Magnitude，EVM)和信噪比(Signal Noise Ratio，SNR)中的任一个。其中，MSE、EVM和SNR中的任一个均可以表征信号传输时的链路状态的质量。
结合第一方面和上述可能的实现方式，在本申请的另一种可能的实现方式中，站点A可以通过周期性的接收站点B发送的链路状态指示，实时地监控站点A到站点B的链路状态的质量。站点A可以根据周期性接收的链路状态指示，确定是否继续调低PA的漏压。本申请的方法还可以包括：站点A接收站点B发送的第二链路状态指示，该第二链路状态指示包含站点A到站点B的链路状态的参数；若第二链路状态指示包含的参数小于第一阈值且大于第二阈值(第二阈值小于第一阈值)，站点A则停止调低PA的漏压。其中，由于站点A在调低PA的漏压的过程中，可以实时监测链路状态的质量，使得第二链路状态指示包含的参数始终在第一阈值与第二阈值之间，如此便可以在保证通信系统的可靠性的同时，最大限度的降低PA的漏压，实现最大限度的降低PA的功耗。
结合第一方面和上述可能的实现方式，在本申请的另一种可能的实现方式中，当站点A接收的第一链路状态指示包含的参数小于第二阈值时，则表征站点A与站点B之间信号传输时的链路状态的质量较差。为了保证信号能够正常传输，站点A可以调高PA的漏压。本申请的方法还可以包括：若第一链路状态指示包含的参数小于第二阈值，站点A则调高PA的漏压，第二阈值小于第一阈值。其中，由于站点A调高PA的漏压后，可以保证接收的第一链路状态指示包含的参数大于第二阈值，因此站点A调高PA的漏压后，保证了通信系统的可靠性。
结合第一方面和上述可能的实现方式，在本申请的另一种可能的实现方式中，站点A可以根据周期性接收的链路状态指示，确定是否继续调高PA的漏压。本申请的方法还可以包括：站点A接收站点B发送的第三链路状态指示，该第三链路状态指示包含站点A到站点B的链路状态的参数；若第三链路状态指示包含的参数大于第二阈值，则停止调高PA的漏压。其中，由于站点A调高PA的漏压后，第三链路状态指示包含的参数大于第二阈值且小于第一阈值，因此本发明实施例提供的方法，既保证了通信系统的可靠性，又避免了调高PA的漏压后导致PA的漏压太高，使得PA的功耗过大的问题，即该方法也达到了最大限度的降低PA的功耗的目的。
本申请的第二方面，提供一种降低PA的功耗的设备，该降低PA的功耗的设备中包含有PA，本申请的降低PA的功耗的设备可以包括：接收单元和调整单元。其中，接收单元，用于接收站点B发送的第一链路状态指示，该第一链路状态指示包含降低PA的功耗的设备到站点B的链路状态的参数。 调整单元，用于若第一链路状态指示包含的参数大于第一阈值，则调低PA的漏压，以降低PA的功耗。
结合第二方面，在本申请的一种可能的实现方式中，第一链路状态指示包括MSE、EVM和SNR中的任一个。
结合第二方面和上述可能的实现方式，在本申请的另一种可能的实现方式中，上述接收单元，还用于接收站点B发送的第二链路状态指示，该第二链路状态指示包含降低PA的功耗的设备到站点B的链路状态的参数。本申请中的降低PA的功耗的设备还可以包括：第一停止单元。其中，第一停止单元，用于若第二链路状态指示包含的参数小于第一阈值且大于第二阈值，则停止调低PA的漏压，第二阈值小于第一阈值。
结合第二方面和上述可能的实现方式，在本申请的另一种可能的实现方式中，上述调整单元，还用于若第一链路状态指示包含的参数小于第二阈值，则调高PA的漏压，第二阈值小于第一阈值。
结合第二方面和上述可能的实现方式，在本申请的另一种可能的实现方式中，上述接收单元，还用于接收站点B发送的第三链路状态指示，该第三链路状态指示包含降低PA的功耗的设备到站点B的链路状态的参数。本申请中的降低PA的功耗的设备还可以包括：第二停止单元。其中，第二停止单元，用于若第三链路状态指示包含的参数大于第二阈值且小于第一阈值，则停止调高PA的漏压。

本申请的第三方面，提供一种降低PA的功耗的设备，该降低PA的功耗的设备可以包括：处理器、存储器和通信接口。其中，存储器用于存储计算机执行指令，处理器、通信接口与存储器通过总线连接，当降低PA的功耗的设备运行时，处理器执行存储器存储的计算机执行指令，以使降低PA的功耗的设备执行如第一方面以及第一方面的各种可选方式所述的降低PA的功耗的方法。

具体的，本发明实施例中，ODU 03为站点A的射频模块，ODU 03中包含有PA。如图2所示，ODU 03可以包括：中央处理器(Central Processing Unit，CPU)001、变频器002、可变增益放大器(Variable Gain Amplifier，VGA)003、电源模块004和PA 005。其中，CPU 001可以通过线缆与电源模块004 连接；CPU 001和变频器002均可以通过线缆与IDU 02连接(图中未画出)；变频器002、VGA 003、电源模块004和PA 005通过线缆连接；PA 005可以线缆与天线01连接(图中未画出)。
其中，CPU 001是ODU 03的控制中心，其可以负责状态监控(例如，电压、电流和温度等)，可以根据当前状态(如天气、环境等影响链路质量的状态)调整发射功率，可以控制电源模块004调压，可以与IDU 02通信，以及对接收的命令进行处理。例如，CPU 001可以接收IDU 02发送的调压命令，以及对该调压命令进行解析处理。
变频器002是一种信号变频单元，其将IDU 02发送的低频模拟信号上变频至微波频段，通过达到合适的信号频率，使信号能够从天线辐射的设备。
VGA 003是一种调整信号大小的设备，通常站点A中包含多级放大电路(如VGA 003和PA 005)。
电源模块004可以为ODU 03中的各个模块或单元提供供电(例如为PA提供供电)，其电压可编程。
PA 005是一种能输出大功率信号的放大电路，其可以对信号的功率进行放大处理，使得输出端可以提升发射功率，从而调整信号的覆盖范围。
基于图1所示的通信系统以及图2中ODU 03的各模块或组成部分，本发明实施例提供一种降低PA的功耗的方法，该方法对通过调低PA的漏压以降低射频模块的PA的功耗的过程，进行了详细的介绍。具体的，如图3所示，该降低PA的功耗的方法可以包括S301和S302：
S301、站点A接收站点B发送的第一链路状态指示。
其中，第一链路状态指示包含站点A到站点B的链路状态的参数。第一链路状态指示是一种反馈点到点(如站点A到站点B)之间的链路状态的质量的信息，其包含的参数的数值越大，表明链路状态的质量越好。
本发明实施例中，站点A可以在与站点B通信连接后，与站点B进行信息交互。具体的，站点A的ODU 03可以通过天线01向站点B发送信号；站点B对接收的信号进行解析处理，并根据解析的结果得到第一链路状态指示的参数，然后以信息(如第一链路状态指示)的形式将第一链路状态指示的参数传输至站点A的IDU 02。
示例性的，站点A接收站点B发送的第一链路状态指示的具体实现方式可以为：站点A的IDU 02可以对信号进行调制处理，得到低频模拟信号，并将该低频模拟信号传输至ODU 03；ODU 03中的变频器002对信号进行变频处理，得到高频信号，ODU 03中的VGA 003对信号幅度进行调整；ODU 03中的CPU 001根据当前状态(如天气、环境等影响链路质量的状态)，确定链路配置信息(如发射功率以及带宽等)，并以确定的链路配置信息、通过天线01将放大的高频信号发送至站点B；站点B接收到站点A发送的信号后，对信号进行解析处理，并根据解析的结果得到第一链路状态指示的参数，然后站点B以信息(如第一链路状态指示)的形式将第一链路状态指示的参数传输至站点A；站点A的天线01接收第一链路状态指示，并通过ODU 03将第 一链路状态指示传输至IDU 02。
例如，站点B向站点A回传信息时，该信息包括业务信息以及非业务信息，该非业务信息中包括网络管理信息、控制信息、监控信息以及告警信息等，网络管理信息中包括第一链路状态指示。
例如，本发明实施例中的第一链路状态指示可以包括MSE、EVM和SNR中的任一个。MSE、EVM和SNR中的任一个均可以表征信号传输时的链路状态的质量。
S302、若第一链路状态指示包含的参数大于第一阈值，站点A则调低PA的漏压，以降低PA的功耗。
其中，第一阈值为预先设定的用于判定是否调压的门限值(即调压判定门限)，当第一链路状态指示包含的参数大于第一阈值时，则表征信号传输时的链路状态的质量较好，此时如果降低PA的漏压，仍然可以保证信号能够正常传输。
示例性的，此处仅以第一链路状态指示包含的参数为MSE为例，对站点A调低PA的漏压的过程进行说明。具体的，站点A的IDU 02接收到第一链路状态指示后，判断第一链路状态指示包含的参数MSE是否大于第一阈值；若IDU 02判断MSE大于第一阈值，则向ODU 03中的CPU 001下发降压命令；CPU 001在接收到降压命令后，对降压命令进行解析处理，然后控制电源模块004降低其自身的参考电压，以降低PA 005的漏压(即PA 005的供电电压)。其中，CPU 001通过降低电源模块004的参考电压，每次降低的PA005的漏压的幅度值由站点A预先设定的。
例如，假设站点A中的PA 005的当前漏压为6V，站点A预先设定的第一阈值为8，站点A预先设定的每次降低PA 005的漏压的幅度值为0.05V。站点A的IDU 02接收的第一链路状态指示包含的参数为9，IDU 02判断第一链路状态指示包含的参数大于第一阈值，则向CPU 001下发降压命令；CPU001在接收到降压命令后，对降压命令进行解析处理，然后通过控制电源模块004，将PA 005的漏压调低至6V-0.05V(即5.95V)。
由于现有技术中，仅是设置PA的三个等级的发射功率的漏流，而并未对PA的漏压进行调整，因此降低PA的功耗的降幅有限；而本发明实施例中，可以在每个发射功率下针对不同批次的器件，通过链路状态指示最大限度的调低PA的漏压，实现最大限度的降低PA的功耗。
例如，现有技术中，对于不同批次的PA而言，性能较好的PA需要800mA的漏流可以正常工作，而性能较差的PA则需要1000mA的漏流才可以正常工作，为了保证通信系统的可靠性，电源模块提供的漏流为1000mA，此时对于性能较好的PA则会造成漏流的冗余，造成不必要的功耗浪费。
而本发明实施例中，在每个发射功率下，无需考虑器件的批次性的个体差异，只要实时监控通信系统的链路状态，并根据第一链路状态指示调低PA的漏压，便可以在保证通信系统的可靠性的情况下，进一步的降低PA的功耗。
示例性的，如图4(a)所示，为现有技术中PA的三个等级的发射功率 与PA的功耗的关系实例示意图。PA的三个等级中的小发射功率下，PA的功耗为1，PA的三个等级中的中发射功率下，PA的功耗为2，PA的三个等级中的大发射功率下，PA的功耗为3。
如图4(b)所示，为本发明实施例提供的一种降低PA的功耗的方法的效果示意图。其中，图4(b)中的加粗曲线为本发明实施例中的各个发射功率与PA的功耗的关系示意图。
由图4(b)可知，在相同的发射功率下，本发明实施例中的PA的功耗小于现有技术中的PA的功耗，图4(b)中的阴影部分为本发明实施例降低PA的功耗的幅度。因此，本发明实施例提供的降低PA的功耗的方法，进一步的降低了PA的功耗。
本发明实施例提供一种降低PA的功耗的方法，站点A可以根据接收的第一链路状态指示调低PA的漏压，以降低PA的功耗。由于第一链路状态指示用于表征链路状态的质量，当第一链路状态指示包含的参数大于第一阈值时，站点A调低PA的漏压，便可以在保证通信系统的可靠性的情况下，进一步的降低PA的功耗；并且，由于站点A可以实时监控通信系统的链路状态，因此站点A可以在保证通信系统的可靠性的情况下，在不同的发射功率下针对不同批次的器件，通过实时监控的链路状态最大限度的调低PA的漏压，实现最大限度的降低PA的功耗。
当然，本发明实施例中，站点A可以通过周期性的接收站点B发送的链路状态指示，实时地监控站点A到站点B的链路状态的质量。站点A可以根据周期性接收的链路状态指示，确定是否继续调低PA的漏压。具体的，如图5所示，其示出了本发明实施例提供的另一种降低PA的功耗的方法，与图3所示的降低PA的功耗的方法相比，主要是在S302之后增加了S501和S502，在此只对不同的地方进行详细说明，参见图5，该降低PA的功耗的方法包括：
S301、站点A接收站点B发送的第一链路状态指示。
其中，第一链路状态指示包含站点A到站点B的链路状态的参数。
S302、若第一链路状态指示包含的参数大于第一阈值，站点A则调低PA的漏压，以降低PA的功耗。
S501、站点A接收站点B发送的第二链路状态指示。
其中，第二链路状态指示包含站点A到站点B的链路状态的参数。
本发明实施例中，站点A可以在调低PA的漏压的同时，接收站点B发送的第二链路状态指示，第二链路状态指示用于表征调低PA的漏压后，站点A到站点B的链路状态的质量。
例如，本发明实施例中的第二链路状态指示也可以包括MSE、EVM和SNR中的任一个。
需要说明的是，“站点A接收站点B发送的第二链路状态指示的具体实现方式”与“站点A接收站点B发送的第一链路状态指示的具体实现方式”相同，可以参见上述实施例中的具体描述，此处不再进行赘述。
S502、若第二链路状态指示包含的参数小于第一阈值且大于第二阈值， 站点A则停止调低PA的漏压。
其中，第二阈值小于第一阈值。第二阈值为预先设定的用于判定是否继续调压的门限值(即调压防抖门限)。当第二链路状态指示包含的参数小于第二阈值时，则表征信号传输时的链路状态的质量较差，便不能保证信号能够正常传输。
本发明实施例中，站点A可以周期性的接收站点B发送的链路状态指示，当站点A的CPU 001通过控制电源模块004，以调低PA 005的漏压后，站点A的IDU 02接收第二链路状态指示，并判断第二链路状态指示包含的参数是否小于第一阈值且大于第二阈值。当IDU 02判断第二链路状态指示包含的参数大于第一阈值时，则继续向CPU 001发送降压命令；当IDU 02判断第二链路状态指示包含的参数小于第一阈值且大于第二阈值时，则向CPU 001发送停止降压命令。
示例性的，当站点A的IDU 02判断第二链路状态指示包含的参数大于第一阈值时，则继续向CPU 001发送降压命令，使得CPU 001通过控制电源模块004，继续调低PA 005的漏压；并且，IDU 02周期性的接收第二链路状态指示，并判断第二链路状态指示包含的参数是否小于第一阈值且大于第二阈值，直到IDU 02判断接收的链路状态指示包含的参数小于第一阈值且大于第二阈值，才向CPU 001发送停止降压命令；CPU 001在接收到停止降压命令后，对该停止降压命令进行解析处理，然后通过控制停止降低电源模块004的电压，以停止调低PA 005的漏压。
例如，假设站点A预先设定的第二阈值为7。站点A的CPU 001通过控制电源模块004，将PA 005的漏压调低至5.95V；站点A的IDU 02周期性的接收第二链路状态指示，此时的第二链路状态指示包含的参数为8.5，IDU 02判断第二链路状态指示包含的参数大于第一阈值8，则继续向CPU 001下发降压命令；CPU 001在接收到降压命令后，对降压命令进行解析处理，然后通过控制电源模块004，将PA 005的漏压调低至5.95V-0.05V(即5.9V)；站点A的IDU 02周期性的接收第二链路状态指示，此时的第二链路状态指示包含的参数为7.5，IDU 02判断第二链路状态指示包含的参数小于第一阈值8且大于第二阈值7，则向CPU 001下发停止降压命令；CPU 001在接收到停止降压命令后，对该停止降压命令进行解析处理，然后通过控制停止降低电源模块004的电压，以停止调低PA 005的漏压。
由于站点A在调低PA的漏压的过程中，可以实时监测链路状态的质量，使得第二链路状态指示包含的参数始终在第一阈值与第二阈值之间，如此便可以在保证通信系统的可靠性的同时，最大限度的降低PA的漏压，实现最大限度的降低PA的功耗。
可以理解的是，对于不同批次的器件而言，其中性能较好的一部分器件，站点A调低PA的漏压的幅度较大；而其中性能较差的一部分器件，站点A调低PA的漏压的幅度较小。
需要说明的是，本发明实施例中S501与S302同时执行。
进一步的，当站点A接收的第一链路状态指示包含的参数小于第二阈值时，则表征站点A与站点B之间信号传输时的链路状态的质量较差。为了保证信号能够正常传输，站点A可以调高PA的漏压。本发明实施例还提供一种降低PA的功耗的方法，具体的，如图6所示，该降低PA的功耗的方法包括：
S301、站点A接收站点B发送的第一链路状态指示。
其中，第一链路状态指示包含站点A到站点B的链路状态的参数。
S601、若第一链路状态指示包含的参数小于第二阈值，站点A则调高PA的漏压。
其中，第二阈值小于第一阈值。当第一链路状态指示包含的参数小于第二阈值时，则表征信号传输时的链路状态的质量较差，为了保证信号能够正常传输，站点A可以调高PA的漏压，以提高通信系统的可靠性。
示例性的，受天气、环境等的影响，导致站点A与站点B之间的链路状态的质量较差，站点B向站点A发送的第一链路状态指示包含的参数则小于第二阈值。
本发明实施例中，站点A的IDU 02接收到第一链路状态指示后，判断第一链路状态指示包含的参数是否小于第二阈值；当IDU 02判断第一链路状态指示包含的参数小于第二阈值时，则向ODU 03中的CPU 001下发升压命令；CPU 001在接收到升压命令后，对升压命令进行解析处理，然后控制电源模块004调高其自身的参考电压，以调高PA 005的漏压。
当然，本发明实施例中，站点A可以根据周期性接收的链路状态指示，确定是否继续调高PA的漏压。具体的，如图7所示，其示出了本发明实施例提供的另一种降低PA的功耗的方法，与图6所示的降低PA的功耗的方法相比，主要是在S601之后增加了S701和S702，在此只对不同的地方进行详细说明，参见图7，该降低PA的功耗的方法包括：
S301、站点A接收站点B发送的第一链路状态指示。
其中，第一链路状态指示包含站点A到站点B的链路状态的参数。
S601、若第一链路状态指示包含的参数小于第二阈值，站点A则调高PA的漏压。
其中，第二阈值小于第一阈值。
S701、站点A接收站点B发送的第三链路状态指示。
其中，第三链路状态指示包含站点A到站点B的链路状态的参数。
本发明实施例中，站点A可以在调低PA的漏压的同时，接收站点B发送的第二链路状态指示，第三链路状态指示用于表征调高PA的漏压后，站点A到站点B的链路状态的质量。
例如，本发明实施例中的第三链路状态指示也可以包括MSE、EVM和SNR中的任一个。
需要说明的是，“站点A接收站点B发送的第三链路状态指示的具体实现方式”与“站点A接收站点B发送的第一链路状态指示的具体实现方式” 相同，可以参见上述实施例中的具体描述，此处不再进行赘述。
S702、若第三链路状态指示包含的参数大于第二阈值且小于第一阈值，站点A则停止调高PA的漏压。
其中，当第三链路状态指示包含的参数大于第二阈值时，则表征站点A调高PA的漏压后，站点A与站点B之间的链路状态的质量较好，信号能够正常传输。此时如果继续调高PA的漏压，则会导致PA的功耗增大。
本发明实施例中，当站点A的CPU 001通过控制电源模块004，以调高PA 005的漏压的同时，站点A的IDU 02接收第三链路状态指示，并判断第三链路状态指示包含的参数是否大于第二阈值且小于第一阈值。当IDU 02判断第三链路状态指示包含的参数大于第二阈值且小于第一阈值时，则向CPU001发送停止升压命令；CPU 001在接收到停止升压命令后，对该停止升压命令进行解析处理，然后通过控制停止升高电源模块004的电压，以停止调高PA 005的漏压。
由于站点A调高PA的漏压后，第三链路状态指示包含的参数大于第二阈值且小于第一阈值，因此本发明实施例提供的方法，既保证了通信系统的可靠性，又避免了调高PA的漏压后导致PA的漏压太高，使得PA的功耗过大的问题，即该方法也达到了最大限度的降低PA的功耗的目的。
需要说明的是，本发明实施例中S601与S701同时执行。
