Description

一种用于多天线的信号发送方法及装置
本申请要求于2015年08月31日提交中国专利局、申请号为201510548295.0、发明名称为“一种用于多天线的信号发送方法及装置”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
本申请涉及移动通信领域,特别是涉及一种用于多天线的信号发送方法及装置。
背景技术
在移动通信技术领域,可用的频谱资源是有限的,为了提高频谱资源的利用率,引入了多天线技术。
多天线的天馈***一般由多列双极化天线组成;在通信过程中,需要将多个逻辑通道的信号映射到双极化天线的端口上,通过双极化天线将信号传输至接收端。
在现有技术中,逻辑通道到双极化天线的层映射方式采用循环延迟分集(Cyclic Delay Diversity,简称CDD)技术。但是,CDD技术中,由于天线发送信号的时间点不一致,并且天线与用户设备之间的信道状态随时间变化而变化,导致每个天线发送信号时的信道状态不一致,容易形成不平坦的衰落,即在某些地方会形成深度衰落,导致发送信号的性能增益不稳定。
为了提高发送信号的性能增益的稳定性,可以采用多个天线同时发送不同逻辑端口(port)的信号。但是,多个天线同时发送的不同逻辑端口的信号,在被用户设备接收时,可能产生相互干扰。如何降低这种干扰, 是亟待解决的问题。

为使本申请的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本申请作进一步详细的说明。
图1为本申请实施例的双极化天线结构示意图。如图1所示,所述多天线包括8列双极化天线。所述8列双极化天线依次为第一列双极化天线01、第二列双极化天线02、第三列双极化天线03、第四列双极化天线04、第五列双极化天线05、第六列双极化天线06、第七列双极化天线07、第八列双极化天线08。所述8列双极化天线共包括16个天线。
本申请实施例中,可以采用所述8列双极化天线同时发送两个逻辑端口(第一逻辑端口和第二逻辑端口)的信号。第一逻辑端口和第二逻辑端口同时使用所述8列双极化天线发送信号。
所述16个天线可以分为第一组天线、第二组天线、第三组天线和第四组天线。
图2为本申请实施例1的第一组天线和第二组天线的结构示意图。如图2所示,所述第一组天线可以包括第一天线011、第二天线021、第三天线031、第四天线041。所述第二组天线可以包括第五天线051、第六天线061、第七天线071、第八天线081。

图2和图3所示天线中,所述第一组天线中的天线和所述第三组天线中的天线分别依次归属于所述第一列双极化天线01、第二列双极化天线02、第三列双极化天线03、第四列双极化天线04。所述第二组天线中的天线和所述第四组天线中的天线分别依次归属于所述第五列双极化天线05、 第六列双极化天线06、第七列双极化天线07、第八列双极化天线08。
本申请实施例中,可以将所述第一组天线与所述第二组天线的极化方向称为第一极化方向,所述第三组天线与所述第四组天线的极化方向称为第二极化方向,所述第一极化方向与所述第二极化方向正交。
图4为本申请的用于多天线的信号发送方法实施例1的流程图。如图4所示,所述方法可以包括:
步骤401:获取第一逻辑端口的信号在所述第一组天线中依次对应的第一天线的加权权值w0,第二天线的加权权值w1,第三天线的加权权值w2,第四天线的加权权值w3
实际应用中,可以采用现有技术中的方式确定第一组天线中的各个天线的加权权值。当第一组天线中四个天线的加权权值确定以后,可以根据第一组天线中四个天线的加权权值,确定第一逻辑端口的信号对应的另外十二个天线的权值,并且可以确定第二逻辑端口的信号对应的十六个天线的权值。
步骤402:确定所述第一逻辑端口的信号在所述第二组天线中依次对应的第五天线的加权权值为w3,第六天线的加权权值为w2,第七天线的加权权值为w1,第八天线的加权权值为w0
步骤403:确定所述第一逻辑端口的信号在所述第三组天线中依次对应的第九天线的加权权值为w0,第十天线的加权权值为w1,第十一天线的加权权值为w2,第十二天线的加权权值为w3
步骤404:确定所述第一逻辑端口的信号在所述第四组天线中依次对应的第十三天线的加权权值为w3,第十四天线的加权权值为w2,第十五 天线的加权权值为w1,第十六天线的加权权值为w0
通过上述步骤,可以得到第一逻辑端口的信号的加权权值矩阵W0
W0=[w0 w1 w2 w3 w3 w2 w1 w0 w0 w1 w2 w3 w3 w2 w1 w0]
矩阵W0中的16个加权权值从左至右分别与第一至第十六天线相对应。
步骤405:确定第二逻辑端口的信号在所述第一组天线中依次对应的第一天线的加权权值为w3,第二天线的加权权值为w2,第三天线的加权权值为w1,第四天线的加权权值为w0
步骤406:确定所述第二逻辑端口的信号在所述第二组天线中依次对应的第五天线的加权权值为w0,第六天线的加权权值为w1,第七天线的加权权值为w2,第八天线的加权权值为w3
步骤407:确定所述第二逻辑端口的信号在所述第一组天线中依次对应的第九天线的加权权值为w3,第十天线的加权权值为w2,第十一天线的加权权值为w1,第十二天线的加权权值为w0
步骤408:确定所述第二逻辑端口的信号在所述第四组天线中依次对应的第十三天线的加权权值为w0,第十四天线的加权权值为w1,第十五天线的加权权值为w2,第十六天线的加权权值为w3
通过上述步骤,可以得到第二逻辑端口的信号的加权权值矩阵W1
W1=[w3 w2 w1 w0 w0 w1 w2 w3 w3 w2 w1 w0 w0 w1 w2 w3]
矩阵W1中的16个加权权值从左至右分别与第一至第十六天线相对应。
步骤409:对于所述第一逻辑端口的信号,为第m组天线的加权权值 添加负号;
添加负号后,可以使得对应的天线发送的信号的方向变为原方向的反方向。
步骤410:对于所述第二逻辑端口的信号,为第n组天线的加权权值添加负号;其中,m与n的差的绝对值为2;
本申请实施例中,由于天线被划分成四组,所以m的取值为大于或等于1且小于或等于4的整数,n的取值也为大于或等于1且小于或等于4的整数。当m与n的差的绝对值为2时,可以包括以下情况:m=4,n=2;或者,m=3,n=1;或者,m=2,n=4;或者,m=1,n=3。
步骤411:采用所述16个天线中每个天线对应的权值发送所述第一逻辑端口的信号与所述第二逻辑端口的信号。
下面以m=4,n=2的情况,说明本实施例的原理。
当对于所述第一逻辑端口的信号,为第4组天线的加权权值添加负号后,可以得到第一逻辑端口的信号的加权权值矩阵W0变为
W0=[w0 w1 w2 w3 w3 w2 w1 w0 w0 w1 w2 w3 -w3 -w2 -w1 -w0]。
当对于所述第二逻辑端口的信号,为第2组天线的加权权值添加负号后,可以得到第二逻辑端口的信号的加权权值矩阵W1变为
W1=[w3 w2 w1 w0 -w0 -w1 -w2 -w3 w3 w2 w1 w0 w0 w1 w2 w3]。
对于双极化天线,可以将每组的四个天线的信号等效成一个信号。
图5为本申请的用于多天线的信号发送方法实施例1中第一逻辑端口 的信号的等效图。图5中,第一组天线的等效信号为P01,第二组天线的等效信号为P01,第三组天线的等效信号为P02,由于第四组天线的权值具有负号,因此第四组天线的等效信号为-P02。对于图5中的等效信号,进一步合成时,第三组天线与第四组天线的等效信号由于方向相反,大小相等,将被抵消,第一组天线与第二组天线的等效信号由于方向相同,大小相等,将被叠加。叠加后的等效信号理论上可以是2P01
图6为本申请的用于多天线的信号发送方法实施例1中第二逻辑端口的信号的等效图。
图6中,第一组天线的等效信号为P11,由于第二组天线的权值具有负号,因此第二组天线的等效信号-P11,第三组天线的等效信号为P12,第四组天线的等效信号为P12。对于图6中的等效信号,进一步合成时,第一组天线与第二组天线的等效信号由于方向相反,大小相等,将被抵消,第三组天线与第四组天线的等效信号由于方向相同,大小相等,将被叠加。叠加后的等效信号理论上可以是2P12
图7为本申请的用于多天线的信号发送方法实施例1中第一逻辑端口和第二逻辑端口的信号进一步合成后的等效图。如图7所示,最终合成的等效信号为2倍的P01和2倍的P12。由上述推导过程以及图7可以看出,合成后的等效信号中,第一逻辑端口的等效信号P01与第二逻辑端口的等效信号P12,相互正交。因此可以降低用户设备接收信号时,第一逻辑端口的信号与第二逻辑端口的信号产生的相互干扰。
综上所述,本实施例中,通过根据第一组天线中的天线对应于第一逻辑信号的加权权值,确定第一逻辑端口的信号对应的另外十二个天线的权 值,确定第二逻辑端口的信号对应的十六个天线的权值;对于所述第一逻辑端口的信号,为第m组天线的加权权值添加负号;对于所述第二逻辑端口的信号,为第n组天线的加权权值添加负号;其中,m与n的差的绝对值为2;可以使得第一逻辑端口的等效信号与第二逻辑端口的等效信号相互正交,进而降低多个天线同时发送的不同逻辑端口的信号在被用户设备接收时产生的相互干扰。
实际应用中,为了使双极化天线上发送的信号的功率尽量大,达到功率满发的状态,还可以设置w0,w1,w2,w3之间的数值关系,使得所述w0的平方与所述w3的平方之和等于1,所述w1的平方与所述w2的平方之和等于1。
实际应用中,所述第一逻辑端口的信号与所述第二逻辑端口的信号可以为小区专有导频信号(Cell-specific Reference Signal,CRS)。
本申请还提供了另一种用于多天线的信号发送方法。所述多天线包括8列双极化天线,所述8列双极化天线共包括16个天线,所述双极化天线中的一个天线的极化方向为第一极化方向,另一个天线的极化方向为第二极化方向,所述第一极化方向与所述第二极化方向正交。
本实施例中的双极化天线结构与图1所示结构相同。所述16个天线可以分为第一组天线、第二组天线、第三组天线和第四组天线。其中,所述第一组天线包括所述第一列双极化天线01和第二列双极化天线02,所述第二组天线包括所述第三列双极化天线03和第四列双极化天线04,所述第三组天线包括所述第五列双极化天线05和第六列双极化天线06,所述 第四组天线包括所述第七列双极化天线07和第八列双极化天线08。本实施例中,第一逻辑端口使用所述第一组天线和第三组天线发送信号,第二逻辑端口使用所述第二组天线和第四组天线发送信号。
图8为本申请的用于多天线的信号发送方法实施例2的流程图。如图8所示,所述方法可以包括:
步骤801:获取第一逻辑端口的信号对应的加权权值w1
可以采用现有技术的方法确定第一逻辑端口的信号对应的加权权值w1
步骤802:确定第一组天线和第三组天线中每个天线的加权权值为w1
可以得到第一逻辑端口的信号的加权权值矩阵为,
W1=[w1 w1 0 0 w1 w1 0 0 w1 w1 0 0 w1 w1 0 0]。
矩阵W1中的16个加权权值从左至右分别与第一至第十六天线相对应。
其中,由于第一逻辑端口并不使用所述第二组天线和第四组天线发送信号,因此所述第二组天线和第四组天线对应位置的加权权值为0。
步骤803:获取第二逻辑端口的信号对应的加权权值w2
可以采用现有技术的方法确定第二逻辑端口的信号对应的加权权值w2
步骤804:确定第二组天线和第四组天线中每个天线的加权权值为w2
可以得到第二逻辑端口的信号的加权权值矩阵为,
W2=[0 0 w2 w2 0 0 w2 w2 0 0 w2 w2 0 0 w2 w2]。
矩阵W2中的16个加权权值从左至右分别与第一至第十六天线相对 应。
其中,由于第二逻辑端口并不使用所述第一组天线和第三组天线发送信号,因此所述第一组天线和第三组天线对应位置的加权权值为0。
步骤805:改变所述第一组天线中部分天线的加权权值的相位符号,以使所述第一组天线合成的信号的方向为所述第一极化方向;
本实施例中,可以将图1中的双极化天线中由左下指向右上的方向作为第一极化方向,将图1中的双极化天线中由右下指向左上的方向作为第二极化方向。
图9为本申请用于多天线的信号发送方法实施例2中天线的加权权值的相位符号改变之前,第一逻辑端口的信号与天线的权值的对应关系示意图。
为了使所述第一组天线合成的信号的方向为所述第一极化方向,可以有多种相位符号改变方式。例如,可以改变天线9的信号的相位符号,使天线9的信号与天线10的信号方向相反,或者,可以改变天线10的信号的相位符号,使天线10的信号与天线9的信号方向相反。
假设改变改变天线10的信号的相位符号,则第一逻辑端口的信号的加权权值矩阵变为,
W1=[w1 w1 0 0 w1 w1 0 0 w1 -w1 0 0 w1 w1 0 0]
步骤806:改变所述第三组天线中部分天线的加权权值的相位符号,以使所述第三组天线合成的信号的方向为所述第二极化方向;
与步骤805原理相同,假设改变天线5的信号的相位符号,则第一逻辑端口的信号的加权权值矩阵进一步变为,
W1=[w1 w1 0 0 -w1 w1 0 0 w1 -w1 0 0 w1 w1 0 0]
步骤807:改变所述第二组天线中部分天线的加权权值的相位符号,以使所述第二组天线合成的信号的方向为所述第一极化方向;
第二组天线与第四组天线中发送的为第二逻辑端口的信号。
图10为本申请用于多天线的信号发送方法实施例2中天线的加权权值的相位符号改变之前,第二逻辑端口的信号与天线的权值的对应关系示意图。
与步骤805原理相同,改变天线11或天线12的相位符号均可以使所述第二组天线合成的信号的方向为所述第一极化方向。
假设,改变天线11的相位符号,则第二逻辑端口的信号的加权权值矩阵变为,
W2=[0 0 w2 w2 0 0 w2 w2 0 0 w2 -w2 0 0 w2 w2]。
步骤808:改变所述第四组天线中部分天线的加权权值的相位符号,以使所述第四组天线合成的信号的方向为第三极化方向,所述第三极化方向与所述第一极化方向相反;
本实施例中,由于所述第一极化方向为左下指向右上,则所述第三极化方向为右上指向左下,因此,需要将天线7和天线8的相位符号改变,并且将天线15与天线16中的一个天线的相位符号改变。
假设,改变天线7、天线8、天线16的相位符号,则第二逻辑端口的信号的加权权值矩阵进一步变为,
W2=[0 0 w2 w2 0 0 -w2 -w2 0 0 w2 -w2 0 0 w2 -w2]。
步骤809:采用所述16个天线中每个天线对应的权值发送所述第一逻 辑端口的信号与所述第二逻辑端口的信号。
图11为本申请用于多天线的信号发送方法实施例2中第一逻辑端口的信号的等效图。如图11所示,等效后第一逻辑端口的信号为第一极化方向的信号P11和第二极化方向的信号P12
图12为本申请用于多天线的信号发送方法实施例2中第二逻辑端口的信号的等效图。如图12所示,等效后第一逻辑端口的信号为第一极化方向的信号P21和第三极化方向的信号P22
将图11中的等效信号进一步合成,可以得到向上的第一逻辑端口信号,将图12中的等效信号进一步合成,可以得到向右的第二逻辑端口信号。因此,最终合成后的第一逻辑端口的等效信号与第二逻辑端口的等效信号,两者相互正交。
综上所述,本实施例中,通过获取第一逻辑端口的信号对应的加权权值w1,将第一逻辑端口的信号对应的8个天线的权值均设置为w1,获取第二逻辑端口的信号对应的加权权值w2,将第二逻辑端口的信号对应的8个天线的权值均设置为w2;改变所述第一组天线中部分天线的加权权值的相位符号,以使所述第一组天线合成的信号的方向为所述第一极化方向;改变所述第三组天线中部分天线的加权权值的相位符号,以使所述第三组天线合成的信号的方向为所述第二极化方向;改变所述第二组天线中部分天线的加权权值的相位符号,以使所述第二组天线合成的信号的方向为所述第一极化方向;改变所述第四组天线中部分天线的加权权值的相位符号,以使所述第四组天线合成的信号的方向为第三极化方向,所述第三极化方向与所述第一极化方向相反;可以使得第一逻辑端口的等效信号与第二逻 辑端口的等效信号相互正交,进而降低多个天线同时发送的不同逻辑端口的信号在被用户设备接收时产生的相互干扰。
实际应用中,为了使双极化天线上发送的信号的功率尽量大,达到功率满发的状态,可以使得所述w1与w2的值均为1。
实际应用中,所述第一逻辑端口的信号与所述第二逻辑端口的信号为小区专有导频信号(Cell-specific Reference Signal,CRS)。
本申请还提供了一种用于多天线的信号发送装置。所述多天线包括8列双极化天线,所述8列双极化天线共包括16个天线,其特征在于,第一逻辑端口和第二逻辑端口同时使用所述8列双极化天线发送信号,所述16个天线分为第一组天线、第二组天线、第三组天线和第四组天线,所述第一组天线与所述第二组天线的极化方向为第一极化方向,所述第三组天线与所述第四组天线的极化方向为第二极化方向,所述第一极化方向与所述第二极化方向正交;所述8列双极化天线依次为第一列双极化天线、第二列双极化天线、第三列双极化天线、第四列双极化天线、第五列双极化天线、第六列双极化天线、第七列双极化天线、第八列双极化天线;所述第一组天线中的天线和所述第三组天线中的天线分别依次归属于所述第一列双极化天线、第二列双极化天线、第三列双极化天线、第四列双极化天线;所述第二组天线中的天线和所述第四组天线中的天线分别依次归属于所述第五列双极化天线、第六列双极化天线、第七列双极化天线、第八列双极化天线。
