具体实施方式
以下结合说明书附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本申请，并不用于限定本申请，并且在不冲突的情况下，本发明的各实施例及实施例中的特征可以相互组合。
本发明实施例提供一种控制下行数据发射功率的方法。
参照图1，图1为本发明实施例的控制下行数据发射功率的方法的流程示意图。在本实施例中，所述控制下行数据发射功率的方法包括：
步骤S10、在接收到下行数据的发送指令时，确定基站发送下行数据的调制方式。
本步骤S10中，所述确定基站发送下行数据的调制方式可以为：获取基站当前的配置信息，根据所述配置信息确定基站发送下行数据的调制方式。所述基站的配置信息包括：下行数据的调制方式、下行数据的标准发射功率值、下行数据的资源占用信息。
步骤S20、根据所述调制方式确定基站本次发送下行数据的发射功率增加值。
参见图2，图2为图1中步骤S20的实现流程示意图。本步骤S20可以包 括：
步骤S21、根据所述调制方式计算对应的标准发射功率值星座图判决区域上限的提升能量值。
步骤S22、根据所述提升能量值确定基站本次发送下行数据的发射功率增加值。
本步骤S22中，所述本次发送下行数据的发射功率增加值小于所述提升能量值。
步骤S30、确定所述调制方式对应的标准发射功率值与所述发射功率增加值相加的总发射功率值作为基站本次发送下行数据的发射功率值。
本实施例中控制下行数据发射功率的方法可以例如由基站控制器执行，或者也可以由另外设置的专用实体来执行，本发明实施例对此不作限定。
上述实施例中，所述调制方式包括：BPSK调制方式、QPSK调制方式、QAM调制方式等调制方式，其中QAM调制方式包括有16QAM调制方式和64QAM调制方式。上述实施例中，基站发送下行数据的调制方式不同，其标准发射功率星座图判决区域上限的提升能量值不同，因此本次发送下行数据的发射功率增加值的最大值也不同，但最终确定的发射功率增加值可能相同也可能不同；因此最终确定的基站本次发送下行数据的发射功率可能相同也可能不同。例如当采用64QAM调制方式，对应的标准发射功率星座图判决区域上限的提升能量值为：min(20log10(2/1)，20log10(4/3)，20log10(6/5))＝1.58dB，则本次下行数据实际的发射功能值在标准发射功率值的基础上增加的功率值应当小于1.58dB，即所述本次发送下行数据的发射功率增加值应当小于1.58dB。因此基站本次发送下行数据的实际发射功率值大小为：实际发射功率值＜标准发射功率值+1.58dB。当采用16QAM调制方式，对应的标准发射功率星座图判决区域上限的提升能量值为：min(20log10(2/1))＝6.02dB，则本次下行数据实际的发射功能值在标准发射功率值的基础上增加的功率值应当小于6.02dB，即所述本次发送下行数据的发射功率增加值应当小于6.02dB。因此基站本次发送下行数据的实际发射功率值大小为：实际发射功率值＜标准发射功率值+6.02dB。当采用QPSK调制方式，对应的标准发射功率星座图判决区域上限的提升能量值没有限制，因此则基站本次下行数据实际的发射功能值在标准发射功率值的基础上增加的功率值也没有限制，即所述基站本次的发射功率增加值的大小没有限制，可以根据需要在标准发射功率值的基础上增加任意值。本发明实施例采用其他调制方式原理同上，同样是根据调制方式对应的标准发射功率星座图判决区域上限的提升能量值，确定基站本次的 发射功率增加值，该基站本次的发射功率增加值小于对应的标准发射功率星座图判决区域上限的提升能量值，在此不再逐个详细描述。
以上实施例所提出的控制下行数据发射功率的方法，通过在接收到下行数据的发送指令时，确定基站发送下行数据的调制方式；根据所述调制方式确定基站本次发送下行数据的发射功率增加值；确定所述调制方式对应的标准发射功率值与所述发射功率增加值相加的总发射功率值作为基站本次发送下行数据的发射功率值方式，相比现有技术中以标准发射功率值发送下行数据的方式，提高了下行数据发射功率的利用率，提升了系统性能，同时提升了用户的体验效果。
本发明实施例进一步提供一种控制下行数据发射功率的装置。参照图3，图3为本发明实施例的控制下行数据发射功率的装置的功能模块示意图。在本实施例中，所述控制下行数据发射功率的装置100包括：调制方式确定模块110、发射功率增加值确定模块120、发射功率确定模块130。其中所述调制方式确定模块110设置为在接收到下行数据的发送指令时，确定基站发送下行数据的调制方式。所述发射功率确定模块120设置为根据所述调制方式确定基站本次发送下行数据的发射功率增加值。所述发射功率确定模块130设置为确定所述调制方式对应的标准发射功率值与所述发射功率增加值相加的总发射功率值作为基站本次发送下行数据的发射功率值。
上述实施例中，所述调制方式确定模块110可以用于获取基站当前的配置信息，根据所述配置信息确定基站发送下行数据的调制方式。所述基站的配置信息包括：下行数据的调制方式、下行数据的标准发射功率值、下行数据的资源占用信息。
参见图4，图4是图3中发射功率增加值确定模块的功能模块示意图。所述发射功率增加值确定模块120包括：提升能量值计算单元121、发射功率增加值确定单元122。其中，所述提升能量值计算单元121设置为根据所述调制方式计算对应的标准发射功率值星座图判决区域上限的提升能量值。所述发射功率增加值确定单元122设置为根据所述提升能量值确定基站本次发送下行数据的发射功率增加值。
上述实施例中，所述基站本次发送下行数据的发射功率增加值小于所述提升能量值。所述调制方式包括：BPSK调制方式、QPSK调制方式、QAM调制方式等调制方式，其中QAM调制方式包括有16QAM调制方式和64QAM调制方式。上述实施例中，基站发送下行数据的调制方式不同，其标准发射功率星座图判决区域上限的提升能量值不同，因此基站本次发送下行数据的 发射功率增加值的最大值也不同，但最终确定的发射功率增加值可能相同也可能不同；因此最终确定的基站本次发送下行数据的发射功率可能相同也可能不同。例如当采用64QAM调制方式，对应的标准发射功率星座图判决区域上限的提升能量值为：min(20log10(2/1)，20log10(4/3)，20log10(6/5))＝1.58dB，则基站本次下行数据实际的发射功能值在标准发射功率值的基础上增加的功率值应当小于1.58dB，即所述基站本次发送下行数据的发射功率增加值应当小于1.58dB。因此基站本次发送下行数据的实际发射功率值大小为：实际发射功率值＜标准发射功率值+1.58dB。当采用16QAM调制方式，对应的标准发射功率星座图判决区域上限的提升能量值为：min(20log10(2/1))＝6.02dB，则基站本次下行数据实际的发射功能值在标准发射功率值的基础上增加的功率值应当小于6.02dB，即所述基站本次发送下行数据的发射功率增加值应当小于6.02dB。因此基站本次发送下行数据的实际发射功率值大小为：实际发射功率值＜标准发射功率值+6.02dB。当采用QPSK调制方式，对应的标准发射功率星座图判决区域上限的提升能量值没有限制，因此则基站本次下行数据实际的发射功能值在标准发射功率值的基础上增加的功率值也没有限制，即所述基站本次的发射功率增加值的大小没有限制，可以根据需要在标准发射功率值的基础上增加任意值。本发明实施例采用其他调制方式原理同上，同样是根据调制方式对应的标准发射功率星座图判决区域上限的提升能量值，确定基站本次的发射功率增加值，该基站本次的发射功率增加值小于对应的标准发射功率星座图判决区域上限的提升能量值，在此不再逐个详细描述。
上述实施例所提出的控制下行数据发射功率的装置100，通过调制方式确定模块110在接收到下行数据的发送指令时，确定基站发送下行数据的调制方式；发射功率增加值确定模块120根据所述调制方式确定基站本次发送下行数据的发射功率增加值；发射功率确定模块130确定所述调制方式对应的标准发射功率值与所述发射功率增加值相加的总发射功率值作为基站本次发送下行数据的发射功率值方式，相比现有技术中以标准发射功率值发送下行数据的方式，提高了下行数据发射功率的利用率，提升了系统性能，同时提升了用户的体验效果。
本发明实施例还提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令在由处理器执行时用于执行上述实施例中所述的方法。
本文是参照根据本发明实施例的方法、设备和计算机程序产品的流程图 和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
