Description

一种功率放大器控制装置及方法
本申请要求于2014年12月2日提交中国专利局、申请号为201410720344.X、发明名称为“一种功率放大器控制装置及方法”的国内申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及基站设备控制技术领域，更具体地说，涉及一种功率放大器控制装置及方法。
背景技术
LTE(Long Term Evolution，长期演进)是3GPP网络UMTS(Universal Mobile Telecommunications System，通用移动通信***)的演进网络，它改进并增强了3G的空中接入技术，采用OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)和MIMO(Multiple-Input Multiple-Output，多输入多输出)作为其无线网络演进的技术。
为了满足LTE通信制式下数据业务的增长，同时提高频谱利用效率，运营商通过重整已有GSM(Global System for Mobile Communication，全球移动通信***)制式下的频谱加快LTE部署。例如，运营商在1800MHz通常有比较丰富的频谱，随着LTE 1800MHz的终端产业链成熟已日趋成熟，运营商会降低GSM 1800配置，在1800频段清理10M(兆)或是15M带宽给LTE通信制式下的数据业务使用，以使GSM通信制式和LTE通信制式共享1800频段。
对于这样多通信制式共享频段来说，多采用多模基站对共享频段进行部署，使GSM通信制式和LTE通信制式共享MSR基站的射频模块，以支持后续网络持续演尽，从而降低站点成本。但由于GSM通信制式和LTE通信制式共享同一个射频模块，导致原先针对单通信制式设计的控制射频模块中功率放大器的方法不再适用于多种通信制式下对功率放大器的控制，因此急需为多通信制式提供一种功率放大器控制方法，以降低多模基站的能耗。

附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中 所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为现有技术中单天线口导频图案的子帧的示意图；
图2为本发明实施例提供的功率放大器控制装置的一种结构示意图；
图3为本发明实施例提供的GSM通信制式和LTE通信制式的时隙结构示意图；
图4为本发明实施例提供的数据发送情况示意图；
图5为本发明实施例提供的LTE通信制式和UMTS通信制式的时隙结构示意图；
图6为本发明实施例提供的功率放大器控制装置的另一种结构示意图；
图7为本发明实施例提供的功率放大器控制方法的流程图；
图8为本发明实施例提供的多模基站的结构示意图。
具体实施方式
目前多模基站可以应用于多种通信制式下，以多模基站应用于GSM通信制式和LTE通信制式为例，GSM通信制式下的最小数据发送单位为时隙，其时长为(15/26)ms。当多模基站应用于GSM通信制式下时，多模基站可以根据时隙上是否有数据发送对功率放大器进行控制。比如8个时隙中只有1个时隙上有数据发送，其它7个时隙上无数据发送，则多模基站可以控制在有数据发送的时隙内控制功率放大器开启，相应的在无数据发送的时隙内控制功率放大器关闭，即在GSM通信制式下多模基站控制功率放大器的开启和关闭动作在时隙级时间内完成，以节省时隙空闲时功率放大器为保持线性工作区固定偏置电压消耗的能耗。
LTE通信制式下的最小数据发送单位为符号，其时长为(0.5/7)ms，当多模基站应用于LTE通信制式下时，多模基站动态检测哪些符号上没有数据发送，并在这些没有数据发送的符号的时长内关闭功率放大器，而在有数据发送的符号的时长内开启功率放大器。以单天线口导频图案的子帧为例，如 图1所示，图1中R0表示有数据发送，则在图1所示的子帧中符号#1、#2、#3、#5、#6时长内可以关闭功率放大器。
由上述分析可以看出，多模基站在每种通信制式下采用各自的最小数据发送单位的时长控制功率放大器的关闭和开启，而每种通信制式下最小数据发送单位的时长不同，因此多模基站中原先针对单通信制式设计的控制射频模块中功率放大器的方法不再适用于多种通信制式下对功率放大器的控制。
为解决这一问题，本发明实施例提供的功率放大器控制装置及方法的核心思想则是获取每种通信制式下最小数据发送单位的时长，并选取较小的时长为基准控制功率放大器的关闭和开启。
为了使本领域技术人员更好地理解本发明，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图2，其示出了本发明实施例提供的一种功率放大器控制装置的一种结构，应用于多模基站中，该多模基站应用于第一通信制式和第二通信制式下，且第一通信制式和第二通信制式不同，其中图2所示的功率放大器控制装置可以包括：第一获取单元11、第一判断单元12、第二判断单元13、第二获取单元14和第一控制单元15。其中，
第一获取单元11，用于获取多模基站在第一通信制式下的第一业务情况以及多模基站在第二通信制式下的第二业务情况。
其中第一通信制式和第二通信制式为多模基站应用的两种通信基准，如前述GSM通信制式和LTE通信制式，为了能够在第一通信制式和第二通信制式下控制功率放大器，首先需要获取多模基站在第一通信制式下的第一业务情况以及在第二通信制式下的第二业务情况，第一业务情况和第二业务情况可以表明是否有数据发送，进而可以以是否有数据发送来控制功率放大器的关闭和开启。
在本发明实施中，第一获取单元11可以以数据采样结果作为表明业务情况的一种方式，例如第一获取单元11可以从当前第一通信制式下的第一发送单位的初始时刻开始，在第一预设时间段内对第一发送单位进行数据采样， 获取表明第一业务情况的第一数据采样结果。相应的第一获取单元11可以从当前第二通信制式下的第二发送单位的初始时刻开始，在第二预设时间段内对第二发送单位进行数据采样，获取表明第二业务情况的第二数据采样结果。
其中第一预设时间段和第二预设时间段是可以保证第一获取单元11能够采集足够的数据来表明当前在第一发送单位和第二发送单位上的业务情况的数据采样结果，第一获取单元11所设置的采样时间，具体可以根据多模基站对业务情况判断的精准度来设置。
第一判断单元12，用于依据第一业务情况判断当前的第一发送单位上是否有数据发送，其中第一发送单位是第一通信制式下的最小数据发送单位。
以第一通信制式为GSM通信制式为例，第一发送单位为时隙。当依据第一业务情况判断出当前的第一发送单位上有数据发送，功率放大器控制装置需要开启功率放大器来发送数据。当依据第一业务情况判断出当前的第一发送单位上无数据发送时，功率放大器控制装置需要进一步判断第二通信制式下的第二发送单位上是否有数据发送，然后依据第二发送单位上是否有数据发送的判断结果控制功率放大器的开启和关闭。
在第一业务情况采用第一数据采样结果表示的情况下，第一判断单元12判断当前的第一发送单位上是否有数据发送的可行方式是：判断第一数据采样结果中从初始时刻开始的连续N次采样到的数据是否为0，即从初始时刻开始在连续采样N次所得到的每个数据是否都为0，如果每个数据都是0则说明第一发送单位上无数据发送；如果有任意一个数据不是0则说明第一发送单位上有数据发送。
第二判断单元13，用于依据第二业务情况判断当前的第二发送单位上是否有数据发送，其中第二发送单位是第二通信制式下的最小数据发送单位。
以第二通信制式为LTE通信制式为例，第二发送单位为符号。当依据第二业务情况判断出当前的第二发送单位上有数据发送，功率放大器控制装置需要开启功率放大器来发送数据。当依据第二业务情况判断出当前的第二发送单位上无数据发送时，功率放大器控制装置可以关闭功率放大器来降低多模基站的功耗。
在第二业务情况采用第二数据采样结果表示的情况下，第二判断单元13判断当前的第二发送单位上是否有数据发送的可行方式是：判断第二数据采 样结果中从初始时刻开始的连续N次采样到的数据是否为0，即从初始时刻开始在连续采样N次所得到的每个数据是否都为0，如果每个数据都是0则说明第二发送单位上无数据发送；如果有任意一个数据不是0则说明第二发送单位上有数据发送。
第二获取单元14，用于当第一发送单位上无数据发送且第二发送单位上无数据发送时，获取第一发送单位的时长和第二发送单位的时长中较小的时长。
第一控制单元15，用于以所获取的时长为基准，关闭功率放大器。
以上述GSM通信制式和LTE通信制式为例，GSM通信制式和LTE通信制式的时隙结构如图3所示，其中G表示GSM通信制式，L表示LTE通信制式，其中1LTE时隙包括8个符号，GSM通信制式下最小数据发送单位——时隙的时长(15/26)ms是LTE通信制式下最小数据发送单位——符号(0.5/7)ms的8.08倍，且多模基站中功率放大器具备符号级关断的能力，因此在本发明实施例中功率放大器控制装置可考虑以LTE通信制式下的符号为最小粒度控制功率放大器的开启和关闭，即在开启和关闭功率放大器的时长最长为LTE通信制式下的符号的时长。这样当第一发送单位上无数据发送且第二发送单位上无数据发送时，第二获取单元14所获取的时长则是LTE通信制式下最小数据发送单位——符号(0.5/7)ms，第一控制单元15以(0.5/7)ms为基准关闭功率放大器。
与图3所示的时隙结构相对应，数据发送情况可以以电平高低表示，例如图4所示，图4中横坐标表示时长，纵坐标表示数据发送情况，其中电平1表示无数据发送，电平0表示有数据发送，当GSM通信制式下的时隙上有数据发送或LTE通信制式下的符号上有数据发送时，则控制功率放大器(PA)开启，否则控制功率放大器关闭，如图4中的PA OFF表示功率放大器关闭。
在以图4所示电平高低表示数据发送情况时，第一控制单元15可以将图4所示的每种通信制式下的表示数据发送情况的电平作为设置在多模基站的与门的输入信号，由与门的输出信号控制功率放大器。其控制原理是：当电平表示至少一个通信制式有数据发送时，与门输出控制功率放大器开启的输出信号；当电平表示多模基站下的所有通信制式均无数据发送时，与门输出控制功率放大器关闭的输出信号，具体的是：当与门的输出信号为1时，表 示所有通信制式下均无数据发送，则控制功率放大器关闭；当与门的输出信号为0时，表示至少一个通信制式下有数据发送，则控制功率放大器开启。
从上述图4以及图4所对应的逻辑运算方式可以看出，本发明实施例中对功率放大器的控制需要满足的条件是：当多模基站下的至少一个通信制式有数据发送时，控制功率放大器开启；当多模基站下的所有通信制式均无数据发送时，控制功率放大器关闭。因此在满足上述控制功率放大器的条件下，在本发明实施例中还可以采用其他的逻辑运算方式来控制功率放大器的开启和关闭，对此本发明实施例不再一一列举。
此外本发明实施例提供的功率放大器控制装置还可以应用于两种通信制式为LTE通信制式和UMTS(Universal Mobile Telecommunications System，通用移动通信***)通信制式的多模基站中，LTE通信制式和UMTS通信制式的时隙结构如图5所示，U表示GSM通信制式，L表示LTE通信制式，其中1LTE时隙包括8个符号，UMTS通信制式下每个时隙长度10ms/15约为667us，大约是LTE通信制式下的符号的9.3倍，因此在两种通信制式下均无数据发送时，可考虑以LTE通信制式下的符号为最小粒度控制功率放大器的开启和关闭。
需要说明的是，由于UMTS采用码分复用的传输方式且导频信道一直传输发送，在当前传统多模基站架构下，导频和数据采用同一功率放大器，则功率放大器不能单独按照数据传输进行关闭和开启。对于数据和导频采用分离功放承载的多模基站架构来说，则可按照本发明实施例提供的功率放大器方法，按照两个通信制式下数据发送情况，动态关闭和开启承载数据业务的功率放大器。
应用上述技术方案，功率放大器控制装置可以在第一通信制式下的第一发送单位上无数据发送，且在第二通信制式下的第二发送单位上无数据发送时，获取第一发送单位的时长和所述第二发送单位的时长中较小的时长，并以所获取的时长为基准，关闭功率放大器，使多模基站可以在多种通信制式下控制功率放大器的关闭，降低多模基站的能耗。
在上述图2基础上，本发明实施例提供的功率放大器控制装置还可以包括第二控制单元16，如图6所示，其中第二控制单元，用于当第一发送单位上有数据发送或者第二发送单位上有数据发送时，开启功率放大器。
此外在本发明实施例中，第一控制单元15以所获取的时长为基准关闭功率放大器的一种可行方式是：控制功率放大器关闭的时长小于所获取的时长。例如在以LTE通信制式下的符号为最小粒度控制功率放大器的开启和关闭时，第一控制单元15可以以小于LTE通信制式下的符号的时长为关闭时长控制功率放大器关闭。
另一种可行方式是：第一控制单元15还可以预先设置的功率放大器的关闭时长，由第一控制单元15中的比较子单元将预先设置的功率放大器的关闭时长与所获取的时长进行比较，当关闭时长小于等于所获取的时长时，第一控制单元15中的第一控制子单元控制功率放大器在关闭时长内处于关闭状态，否则当关闭时长大于所获取的时长时，第一控制单元15中的第二控制子单元控制功率放大器在所获取的时长内处于关闭状态。
其中预先设置的关闭时长为关闭功率放大器的情况下并不影响多模基站数据发送的时长，对此本发明实施例并不限定其具体数值。
与上述装置实施例相对应，本发明实施例还提供一种功率放大器控制方法。请参阅图7，其示出了本发明实施例提供的一种功率放大器控制方法，应用于多模基站中，该多模基站应用于第一通信制式和第二通信制式下，且第一通信制式和第二通信制式不同，其中图7所示的功率放大器控制方法可以包括以下步骤：
101：获取多模基站在第一通信制式下的第一业务情况以及多模基站在第二通信制式下的第二业务情况。
其中第一通信制式和第二通信制式为多模基站应用的两种通信基准，如前述GSM通信制式和LTE通信制式，为了能够在第一通信制式和第二通信制式下控制功率放大器，首先需要获取多模基站在第一通信制式下的第一业务情况以及在第二通信制式下的第二业务情况，而第一业务情况和第二业务情况可以表明是否有数据发送，进而可以以是否有数据发送来控制功率放大器的关闭和开启。
在本发明实施中，多模基站可以以数据采样结果作为表明业务情况的一种方式，例如多模基站可以从当前第一通信制式下的第一发送单位的初始时刻开始，在第一预设时间段内对第一发送单位进行数据采样，获取表明第一 业务情况的第一数据采样结果。相应的多模基站可以从当前第二通信制式下的第二发送单位的初始时刻开始，在第二预设时间段内对第二发送单位进行数据采样，获取表明第二业务情况的第二数据采样结果。
其中第一预设时间段和第二预设时间段是可以保证多模基站能够采集足够的数据来表明当前在第一发送单位和第二发送单位上的业务情况的数据采样结果，多模基站所设置的采样时间，具体可以根据多模基站对业务情况判断的精准度来设置。
102：依据第一业务情况判断当前的第一发送单位上是否有数据发送，如果是，执行步骤106；如果否，执行步骤103。
其中第一发送单位是第一通信制式下的最小数据发送单位，以第一通信制式为GSM通信制式为例，第一发送单位为时隙。当依据第一业务情况判断出当前的第一发送单位上有数据发送，多模基站需要开启功率放大器来发送数据。当依据第一业务情况判断出当前的第一发送单位上无数据发送时，多模基站需要进一步判断第二通信制式下的第二发送单位上是否有数据发送，然后依据第二发送单位上是否有数据发送的判断结果控制功率放大器的开启和关闭。
在第一业务情况采用第一数据采样结果表示的情况下，判断当前的第一发送单位上是否有数据发送的可行方式是：判断第一数据采样结果中从初始时刻开始的连续N次采样到的数据是否为0，即从初始时刻开始在连续采样N次所得到的每个数据是否都为0，如果每个数据都是0则说明第一发送单位上无数据发送；如果有任意一个数据不是0则说明第一发送单位上有数据发送。
103：依据第二业务情况判断当前的第二发送单位上是否有数据发送，如果是，执行步骤104，如果否，执行步骤106。
其中第二发送单位是第二通信制式下的最小数据发送单位，以第二通信制式为LTE通信制式为例，第二发送单位为符号。当依据第二业务情况判断出当前的第二发送单位上有数据发送，多模基站需要开启功率放大器来发送数据。当依据第二业务情况判断出当前的第二发送单位上无数据发送时，多模基站可以关闭功率放大器来降低多模基站的功耗。
在第二业务情况采用第二数据采样结果表示的情况下，判断当前的第二发送单位上是否有数据发送的可行方式是：判断第二数据采样结果中从初始 时刻开始的连续N次采样到的数据是否为0，即从初始时刻开始在连续采样N次所得到的每个数据是否都为0，如果每个数据都是0则说明第二发送单位上无数据发送；如果有任意一个数据不是0则说明第二发送单位上有数据发送。
104：获取第一发送单位的时长和第二发送单位的时长中较小的时长。
105：以所获取的时长为基准，关闭功率放大器。
以图3所示的上述GSM通信制式和LTE通信制式的时隙结构为例，其中1LTE时隙包括8个符号，GSM通信制式下最小数据发送单位——时隙的时长(15/26)ms是LTE通信制式下最小数据发送单位——符号(0.5/7)ms的8.08倍，且多模基站中功率放大器具备符号级关断的能力，因此在本发明实施例中多模基站可考虑以LTE通信制式下的符号为最小粒度控制功率放大器的开启和关闭，即在开启和关闭功率放大器的时长最长为LTE通信制式下的符号的时长。即当GSM通信制式和LTE通信制式下无数据发送时，多模基站获取的时长为LTE通信制式下最小数据发送单位——符号(0.5/7)ms，以该(0.5/7)ms为基准关闭功率放大器。
与图3所示的时隙结构相对应，数据发送情况可以以电平高低表示，例如图4所示，图4中横坐标表示时长，纵坐标表示数据发送情况，其中电平1表示无数据发送，电平0表示有数据发送，当GSM通信制式下的时隙上有数据发送或LTE通信制式下的符号上有数据发送时，则多模基站控制功率放大器(PA)开启，否则控制功率放大器关闭，如图4中的PA OFF表示功率放大器关闭。
多模基站在以图4所示电平高低表示数据发送情况时，多模基站可以将图4所示的每种通信制式下的表示数据发送情况的电平作为设置在多模基站的与门的输入信号，由与门的输出信号控制功率放大器。其控制原理是：当电平表示至少一个通信制式有数据发送时，与门输出控制功率放大器开启的输出信号；当电平表示多模基站下的所有通信制式均无数据发送时，与门输出控制功率放大器关闭的输出信号，具体的是：当与门的输出信号为1时，表示所有通信制式下均无数据发送，则控制功率放大器关闭；当与门的输出信号为0时，表示至少一个通信制式下有数据发送，则控制功率放大器开启。
从上述图4以及图4所对应的逻辑运算方式可以看出，本发明实施例中对功率放大器的控制需要满足的条件是：当多模基站下的至少一个通信制式 有数据发送时，控制功率放大器开启；当多模基站下的所有通信制式均无数据发送时，控制功率放大器关闭。因此在满足上述控制功率放大器的条件下，在本发明实施例中还可以采用其他的逻辑运算方式来控制功率放大器的开启和关闭，对此本发明实施例不再一一列举。
此外本发明实施例提供的功率放大器控制方法还可以应用于两种通信制式为LTE通信制式和UMTS通信制式的多模基站中，LTE通信制式和UMTS通信制式的时隙结构如图5所示，U表示GSM通信制式，L表示LTE通信制式，其中1LTE时隙包括8个符号，UMTS通信制式下每个时隙长度10ms/15约为667us，大约是LTE通信制式下的符号的9.3倍，因此在两种通信制式下均无数据发送时，可考虑以LTE通信制式下的符号为最小粒度控制功率放大器的开启和关闭。
需要说明的是，由于UMTS采用码分复用的传输方式且导频信道一直传输发送，在当前传统多模基站架构下，导频和数据采用同一功率放大器，则功率放大器不能单独按照数据传输进行关闭和开启。对于数据和导频采用分离功放承载的多模基站架构来说，则可按照本发明实施例提供的功率放大器方法，按照两个通信制式下数据发送情况，动态关闭和开启承载数据业务的功率放大器。
106：开启功率放大器。其中开启功率放大器是在第一发送单位上有数据发送或者第二发送单位上有数据发送时开启。
应用上述技术方案，多模基站可以在第一通信制式下的第一发送单位上无数据发送，且在第二通信制式下的第二发送单位上无数据发送时，获取第一发送单位的时长和所述第二发送单位的时长中较小的时长，并以所获取的时长为基准，关闭功率放大器，使多模基站可以在多种通信制式下控制功率放大器的关闭，降低多模基站的能耗。
进一步在本发明实施例中以所获取的时长为基准关闭功率放大器的一种可行方式是：控制功率放大器关闭的时长小于所获取的时长。例如在以LTE通信制式下的符号为最小粒度控制功率放大器的开启和关闭时，可以以小于LTE通信制式下的符号的时长为关闭时长控制功率放大器关闭。
另一种可行方式是：将预先设置的功率放大器的关闭时长与步骤104中所获取的时长进行比较，当关闭时长小于等于所获取的时长时，控制功率放 大器在关闭时长内处于关闭状态；当关闭时长大于所获取的时长时，控制功率放大器在所获取的时长内处于关闭状态。其中预先设置的关闭时长为关闭功率放大器的情况下并不影响多模基站数据发送的时长，对此本发明实施例并不限定其具体数值。
此外本发明实施例还提供一种多模基站，该多模基站应用于第一通信制式和第二通信制式下，且所述第一通信制式和所述第二通信制式不同，如图8所示多模基站20在硬件上可包括CPU(Central Processing Unit，中央处理器)21和存储器22。其中,CPU21通过运行存储在存储器22内的软件程序23至少可执行如下步骤：
获取所述多模基站在所述第一通信制式下的第一业务情况以及所述多模基站在所述第二通信制式下的第二业务情况；
依据所述第一业务情况判断当前的第一发送单位上是否有数据发送，其中所述第一发送单位是所述第一通信制式下的最小数据发送单位；
依据所述第二业务情况判断当前的第二发送单位上是否有数据发送，其中所述第二发送单位是所述第二通信制式下的最小数据发送单位；
当所述第一发送单位上无数据发送且所述第二发送单位上无数据发送时，获取所述第一发送单位的时长和所述第二发送单位的时长中较小的时长；
以所获取的时长为基准，关闭所述功率放大器；
当所述第一发送单位上有数据发送或者所述第二发送单位上有数据发送时，开启所述功率放大器。
对于方法实施例而言，由于其基本相应于装置实施例，所以相关之处参见方法实施例的部分说明即可。以上所描述的装置实施例仅仅是示意性的，其中所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多种网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。本领域普通技术人员在不付出创造性劳动的情况下，即可以理解并实施。
在本申请所提供的几个实施例中，应该理解到，所揭露的装置和方法，在没有超过本申请的精神和范围内，可以通过其他的方式实现。当前的实施例只是一种示范性的例子，不应该作为限制，所给出的具体内容不应该限制 本申请的目的。例如，所述单元或子单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多种单元或多种子单元结合一起。另外，多种单元可以或组件可以结合或者可以集成到另一个***，或一些特征可以忽略，或不执行。
以上所述仅是本发明的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
