附图说明
下面将对实施例或相关技术描述中所需要使用的附图作简单地介绍。根据下面参照附图的详细描述，可以更加清楚地理解本公开。
显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
发明人发现，有些终端有多套发射机，这些终端通过多套发射机的多个功率放大器相对于1套发射机的1个功率放大器可以实现更高的功率等级。
本公开实施例，终端在支持发射机切换、且采用1套发射机时的功率等级与采用多套发射机时的功率等级不同的情况下，向基站上报支持多种功率等级的能力信息，使得基站据此对终端的发射功率进行控制，提高上行覆盖范围。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地 描述。
图1示出本公开一些实施例的上报功率的方法的流程示意图。
如图1所示，该实施例的方法包括：步骤110-130a/b。
在步骤110，终端判断是否支持发射机切换。
终端判断是否支持发射机切换包括：如果终端同时支持采用1套发射机发射信号和采用多套发射机发射信号，判定支持发射机切换，否则，判定不支持发射机切换。
例如，如果终端同时支持采用1套发射机发射信号和采用2套发射机发射信号，判定支持发射机切换，否则，判定不支持发射机切换。
在步骤120，终端判断采用1套发射机时的功率等级与采用多套发射机时的功率等级是否相同。
例如，采用1套发射机(含1套功率放大器)时，可实现23dBm的功率等级(设为Power class 3)，采用2套发射机(含2套功率放大器)时，可实现23dBm+23dBm＝26dBm的功率等级(设为Power class2)，此时，判定采用1套发射机时的功率等级与采用2套发射机时的功率等级是不同的。其中，dBm的全称为“decibel relative to one milliwatt”，表示分贝毫瓦，dBm是一个指代功率的绝对值，而不同于dB只是一个相对值。
其中，功率等级表示功率放大器的最大能力，低于该功率等级的功率值该功率放大器也是可以实现的。
在步骤130a，终端在支持发射机切换、且采用1套发射机时的功率等级与采用多套发射机时的功率等级不同的情况下，向基站上报终端支持多种功率等级的能力信息。也即，多种功率等级的能力信息包括：采用1套发射机时的功率等级和采用多套发射机时的功率等级。
例如，终端在支持发射机切换、且采用1套发射机时的功率等级为23dBm、采用2套发射机时的功率等级为26dBm的情况下，向基站上报终端支持多种功率等级的能力信息。
此外，如果终端之前已经向基站上报过支持功率等级23dBm的能力信息，可以向基站新上报支持功率等级26dBm的能力信息。
在一些实施例中，所述终端支持多种功率等级的能力信息包括以下至少一项：支持发射机切换的每个频段组合的功率等级信息，支持发射机切换的每个频段组合内一个或多个频段的功率等级信息。
在步骤130b，终端在不支持发射机切换、或采用1套发射机时的功率等级与采用多套发射机时的功率等级相同的情况下，不向基站上报终端支持多种功率等级的能力信息，或 者，向基站上报终端支持一种功率等级的能力信息。
也即，支持多种功率等级的能力信息的上报终端是可以选择的。若终端支持发射机切换，且上报了支持多种功率等级的能力信息，则在“发射机切换”模式下，采用这套新上报的功率等级。若终端支持发射机切换，且没有上报支持多种功率等级的能力信息，则在“发射机切换”模式下，可以采用与“非发射机切换”模式下相同的能力等级。
在当前网络中，一些性能比较高端的终端有26dBm的功率放大器，然而，在当前网络中，还有很多性能比较中端的终端，这些终端仅有23dBm的功率放大器，但是，通过两个23dBm的功率放大器就可以实现23dBm+23dBm＝26dBm的高功率等级。
上述实施例，终端在支持发射机切换、且采用1套发射机时的功率等级与采用多套发射机时的功率等级不同的情况下，向基站上报支持多种功率等级的能力信息，使得基站据此对终端的发射功率进行控制，提高上行覆盖范围。
上述上报功率的方法可以应用于多频段组网的移动通信网络，根据需要，终端可以增加上报一套新的功率等级的能力信息。
图2示出本公开一些实施例的控制功率的方法的流程示意图。
如图2所示，该实施例的方法包括：步骤210-240。
在步骤210，基站接收终端上报的终端支持多种功率等级的能力信息。
终端支持多种功率等级的能力信息可以是一次上报的，也可以是分多次上报的。
在步骤220，基站根据能力信息，基于终端支持的多种功率等级，对终端的发射功率进行控制。
例如，基站在终端支持的多种功率等级相应的功率范围内，确定终端的发射功率，并通过发射功率控制信息通知终端。
在步骤230，终端接收基站基于能力信息发送的发射功率控制信息。
在步骤240，终端根据发射功率控制信息，选择采用1套发射机或多套发射机发射信号。
例如，如果基站指示终端发射功率为26dBm，并且终端的一套功率放大器的最大能力是23dBm，则终端采用两套发射机(包含2套功率放大器)实现26dBm的发射功率。又例如，如果基站指示终端发射功率为23dBm，则终端采用1套发射机就可以实现23dBm的发射功率。
上述实施例，基站接收终端上报的支持多种功率等级的能力信息，使得基站据此对终端的发射功率进行控制，提高上行覆盖范围。
