Description

波束域的划分方法及装置、存储介质及电子装置
本公开要求于2021年10月29日提交中国专利局、申请号为202111277675.7、发明名称“波束域的划分方法及装置、存储介质及电子装置技”的中国专利申请的优先权,以及要求于2021年12月10日提交中国专利局、申请号为202111511099.8、发明名称“波束域的划分方法及装置、存储介质及电子装置”的中国专利申请的优先权,其全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信领域,具体而言,涉及一种波束域的划分方法及装置、存储介质及电子装置。
背景技术
在无线通信系统中,多用户多入多出(Multiple User Multiple Input MultipleOutput,简称为MU-MIMO)在相同的时频资源上利用空间复用技术进行多个用户的数据传输,显著提高了系统的吞吐量。随着人们对传输速率和服务质量越来越高的要求,在当下的5G新无线(New Radio,简称为NR)和将来的6G中,MU-MIMO将会受到越来越多的关注。
然而,MU-MIMO利用空间复用技术区分多个用户的多流数据时,理论是需要各个用户的信道具有较好的正交性。但是,实际的传输环境中,根据无线通信传输的空间多样性、随机性,不同的用户则有着不同的衰落信道特性,是无法保证用户信道相互正交,相互无干扰的。因此需要尽可能的选择空间域上相关度较小的用户进行配对传输,以获得最好的空间复用增益。如果能将空间域进行一些网格化的划分,基于栅格化机制进行一些用户配对,用户调度等等,将极大的降低搜索复杂度,提高复用增益。
另外,在定位系统中或探测系统中,基于栅格化机制同样可以降低实现复杂度,提高检测性能。
在当前的一些文献中,有对空间的栅格化操作,大都是基于预置波束进行划分,或者基于测量参数进行划分,划分精度不够高,或者划分不够准确,或者重叠划分,使用时需要搜索,复杂度高。
针对相关技术中,传统方法采用预置波束对空间域进行栅格化操作,导致划分精度较低的问题,目前尚未提出有效的解决方案。
因此,有必要对相关技术予以改良以克服相关技术中的所述缺陷。

在本实施例中提供了一种波束域的划分方法,图2是根据本公开实施例的波束域的划分方法的流程图,该流程包括如下步骤:
步骤S202,获取第一组测量数据;
步骤S204,为所述第一组测量数据中的每一测量数据分配第一标签,并通过所述第一标签为所述每一测量数据在空间域中划分所述每一测量数据对应的波束域,其中,所述第一组测量数据中的不同测量数据对应不同的第一标签,所述波束域用于指示所述空间域在进行网 格化的过程中划分的栅格;
步骤S206,将具有所述第一标签的第一组测量数据输入神经网络模型中进行模型训练,得到波束域划分模型;
步骤S208,通过所述波束域划分模型确定第二组测量数据中的每一测量数据对应的第二标签,以根据所述第二标签确定所述第二组测量数据中的每一测量数据在所述空间域中的目标波束域。
通过上述步骤,获取第一组测量数据,并为第一组测量数据中的每一测量数据分配第一标签,进而通过第一标签为每一测量数据在空间域中划分每一测量数据对应的波束域,随后将具有第一标签的第一组测量数据输入神经网络模型中进行模型训练,得到波束域划分模型;通过波束域划分模型确定第二组测量数据中的每一测量数据对应的第二标签,以根据第二标签确定第二组测量数据中的每一测量数据在空间域中的目标波束域。采用上述技术方案,解决了传统方法采用预置波束对空间域进行栅格化操作,导致划分精度较低的问题。进而采用上述技术方案,利用神经网络进行波束域栅格划分,能够学习更复杂的更真实的空间域,使得栅格划分更准确可靠。
进一步地,上述通过所述波束域划分模型确定第二组测量数据中的每一测量数据对应的第二标签,通过以下方式实现:在所述波束域划分模型中确定第一测量数据与第二测量数据的相似度大于预设阈值的情况下,将所述第一测量数据的第一标签确定为所述第二测量数据的第二标签,其中,所述第一组测量数据包括:第一测量数据,所述第二组测量数据包括:第二测量数据;在所述波束域划分模型中确定第二测量数据与所述第一组测量数据中的每一测量数据的相似度都小于所述预设阈值的情况下,为所述第二测量数据分配第二标签,其中,所述第二标签与所述第一组测量数据的第一标签不同。
为了更好的理解上述步骤,以下举例进行说明,假设现在有100个测量数据,需要放入空间域中的栅格中,传统的方法先将空间域划分成固定数量的多个栅格,需要说明的是,一个栅格为一个波束域,不同的栅格存放不同特征的测量数据,进而将100个测量数据根据特征的不同,存放在空间域中固定数量的栅格中。但此种方法,由于空间域已经预先划分好了,所以划分的精度不够高,可能会存在相似度不是很高的两组测量数据放在同一个栅格,即同一个波束域中。
为了解决上述问题,本公开先从100个数据中挑选出特征相似度不高的多个测量数据,假设为5个测量数据(相当于上述实施例中的第一组测量数据),为这5个测量数据分配5个不同的标签1、2、3、4、5(相当于上述实施例中的第一标签),将这5个测量数据分别按照对应的标签划分在空间域中5个不同的波束域,将这5个测量数据存放入这5个对应的波束域中,例如测量数据A在波束域1中,测量数据B在波束域2中,测量数据C在波束域3中,测量数据D在波束域4中,测量数据E在波束域5中。进而将这五个测量数据与波束域的对应关系输入到神经网络模型中进行训练,神经网络模型会学习到测量数据的特征和波束域的对应关系,最后得到波束域划分模型。
需要说明的是,100个数据中还剩下95个数据(相当于上述实施例中的第二组测量数据),将这95个测量数据中的每一个测量数据都输入到波束域划分模型中,假设先将这95个测量数据中的测量数据F输入到波束域划分模型,进而波束域划分模型会将测量数据F的特征与测量数据A-E的特征进行对比,当测量数据F的特征与测量数据A-E中每一个测量数据的特 征相似度都没有达到预设阈值的情况下,波束域划分模型为测量数据F分配一个新的标签(相当于上述实施例中的第二标签),例如6,并根据这个新的标签在空间域中划分新的波束域6,进而可以将测量数据F存放在波束域6中。当测量数据F的特征与测量数据A-E中其中一个测量数据的特征相似度达到预设阈值,例如测量数据F的特征与测量数据A的特征相似度达到预设阈值,波束域划分模型会输出测量数据A的标签,进而可以将测量数据F存放在波束域1中。进而波束域划分模型可以不断的根据新来的测量数据,在空间域中划分波束域。
进一步的,根据所述第二标签确定所述第二组测量数据中的每一测量数据在所述空间域中的目标波束域,可以通过以下方式实现:将所述第二标签中当前待划分波束域的第二标签与多个所述第一标签一一进行比对;在多个所述第一标签中存在与所述当前待划分波束域的第二标签相同的第一标签的情况下,获取与所述当前待划分波束域的第二标签相同的第一标签所对应的第一测量数据,并将所述当前待划分波束域的第二标签对应的测量数据分配至所述第一测量数据的波束域中;在多个所述第一标签中不存在与所述当前待划分波束域的第二标签相同的第一标签的情况下,根据所述当前待划分波束域的第二标签为所述当前待划分波束域的第二标签对应的测量数据在所述空间域中划分目标波束域。
也就是说,将第二组测量数据输入到波束域划分模型以后,会得到多个第二标签,进而需要将这多个第二标签中的每一个当前待划分波束域的第二标签与第一组测量数据中的多个第一标签进行比对。为了更好的理解,举例进行说明,第一测量数据中有5个测量数据,分别有5个第一标签,1、2、3、4、5。第二组测量数据中有2个测量数据,输入到波束域划分模型以后,得到2个第二标签,假设得到的标签为5、6。将这2个第二标签与5个第一标签进行对比。从对比结果可知,这2个第二标签中存在一个标签与5个第一标签中的一个标签相同,进而将第二组测量数据中标签5对应的测试数据,存放在原有的标签5对应的波束域5中。而对于标签6,在这5个第一标签中都没有,进而需要根据标签6在空间域中新划分一个波束域,将标签6对应的测量数据存放在新划分的标签6对应的波束域6中。
需要说明的是,为了让波束域划分模型知道测量数据6是存放在波束域6中的,进而需要将测量数据6对应波束域6的关系输入到波束域划分模型中,让波束域划分模型重新训练。具体的,可以通过以下方式实现:将所述当前待划分波束域的第二标签对应的测量数据添加到所述波束域划分模型进行模型训练,得到目标波束域划分模型;将所述波束域划分模型替换为所述目标波束域划分模型。
进一步地,为了更好的理解波束域划分模型是如何训练出来的,具体的,需要对具有所述第一标签的第一组测量数据中的每一测量数据进行特征提取,以得到所述每一测量数据的多维特征数据;将所述每一测量数据的多维特征数据的格式转化为目标格式,其中,所述目标格式为所述神经网络模型所匹配的格式;将具有所述目标格式的所述每一测量数据的多维特征数据输入所述神经网络模型中进行模型训练,得到波束域划分模型。
也就是说,需要从第一组测量数据中的每一个测量数据中提取对应的多维特征数据,并且将多维特征数据与第一标签的对应关系输入到神经网络模型中进行训练,进而才可以确定波束域划分模型,让波束域划分模型知道哪一个测量数据对应哪一个波束域。
进一步地,将具有所述第一标签的第一组测量数据输入神经网络模型中进行模型训练,得到波束域划分模型,还通过以下方式实现:将具有所述第一标签的第一组测量数据划分为训练集数据和测试集数据;将所述训练集数据输入所述神经网络模型中进行模型训练,得到 第一神经网络模型;将所述测试集数据输入所述第一神经网络模型中,得到第一测试结果;在所述第一测试结果满足预设条件的情况下,将所述第一神经网络模型确定为波束域划分模型;在所述第一测试结果不满足预设条件的情况下,通过调整所述神经网络模型的参数配置再次进行模型训练。
需要说明的是,通过调整所述神经网络模型的参数配置再次进行模型训练,需要调整神经网络模型的参数配置,并将训练集数据添加到调整后的神经网络模型中进行训练,得到第二神经网络模型;将所述测试集数据输入所述第二神经网络模型中,得到第二测试结果;并在第二测试结果满足预设条件的情况下,将所述第二神经网络模型确定为波束域划分模型。
需要说明的是,参数配置包括:迭代次数、神经网络层数、神经元数,激活函数。需要说明的是,在一个可选的实施例中,还可以直接对第三组测量数据进行数据预处理,得到数据预处理后的第三组测量数据,其中,所述第三组测量数据包括:所述第一组测量数据,所述第二组测量数据;将所述数据预处理后的第三组测量数据通过聚类算法进行聚类处理,得到第三标签;通过所述第三标签为所述第三组测量数据中的每一测量数据在空间域中划分所述每一测量数据对应的波束域。
也就是说,可以直接将第一组测量数据与第二组测量数据一起通过聚类算法确定第一组测量数据和第二组测量数据中每一个测量数据对应的第三标签,并通过第三标签在空间域中划分对应的波束域,将每一个测量数据保存进划分好的波束域中。
显然,上述所描述的实施例仅仅是本公开一部分的实施例,而不是全部的实施例。为了更好的理解上述波束域的划分方法,以下结合实施例对上述过程进行说明,但不用于限定本公开实施例的技术方案,具体地:
需要说明的是。本公开适用于无线通信系统,尤其是长期演进(Long Term Evolution,简称为LTE)和5G NR无线通信系统中利用MUMIMO进行数据传输时的用户选择、用户调度,或者在单用户多入多出(Single User Multiple Input Multiple Output,简称为SU-MIMO)传输中,最优波束的选择领域。
本公开实施例提出了一种基于机器学习的波束域栅格划分方法,使得可以构建更复杂更真实的空间域,使得栅格划分更准确可靠,主要分为基于神经网络的波束域划分方法和基于聚类的波束域划分方法。
其中,基于神经网络的波束域划分方法主要分为四个阶段:数据初始收集与预处理、模型训练模块、在线检测模块、反馈优化模块。图3是根据本公开实施例的基于神经网络的波束域划分方法的示意图,如图3所示。
一、数据初始收集与预处理
数据初始收集与预处理模块包括:数据收集、筛选处理、自动标签处理、数据预处理模块。
a.数据收集
在初始阶段,收集一段时间的用户数据(相当于上述实施例中的测量数据),包含但不限于基站侧测量的信道探测参考信号(Sounding Reference Signal,简称为SRS)信道响应、信号与干扰加噪声比(Signal to Interference plus Noise Ratio,简称为SINR)值,预编码矩阵指示(Precoding Matrix Indicator,简称为PMI)值,信道质量指示(Channel Quality Indicator,简称为CQI)值,波达方向(Direction of Arrival,简称为DOA)值 等等,根据实际的机器学习的输入数据设计而定。
b.筛选处理
本模块的目的主要是去除掉一些异常数据,使得训练样本数据尽可能的是真实有效的用户业务数据。筛选准则包含但不限于根据SINR,将SINR较低的数据滤除掉。
c.自动标签处理
根据实际基站的覆盖范围,预置波束域栅格表。一般基站是三扇区覆盖,水平辐射范围为正负60度,下倾角一般在正负15度范围,按照水平和垂直5度的步长进行划分。图4是根据本公开实施例的波束域与标签的对应关系示意图,则二维的预置波束域划分为如下图4所示。
如果有上报的DOA测量量,则利用上报的DOA值,如果没有,根据SRS信道估计值及天线阵列模式,计算垂直向和水平向的协方差矩阵,将协方差矩阵变换到角度域估计垂直向和水平向角度。根据估计出的垂直和水平向角度,判断归属预置波束域栅格的哪个栅格,进行标签的设置,这样训练用户数据与标签就建立起一一对应关系。可以利用预置波束域栅格里的标签,也可以重新设置标签,也可以利用垂直和水平向角度的组合作为标签。本模块的目的,一是在数据样本不够覆盖整个栅格时,尽可能选择收集波束域栅格零散分布的栅格数据作为训练样本,如图4中灰色的栅格所示;二是在给预测的新类标定标签。
d.数据预处理
提取多维数据特征,将数据预处理为机器学习所需要的数据格式。其中多维数据特征包括:
(1)SRS信道协方差矩阵:表征了用户的垂直向信息和水平向信息;
(2)SINR:表征了覆盖信息,用户所处的区域位置;
(3)PMI:表征了用户的波束方向信息;
(4)CQI:表征了信道质量信息;
(5)DOA:表征了用户的垂直向信息和水平向信息;
需要说明的是,可实现的多维数据特征可由上述的一种或多种组合构成。包含但不限于以下组合:
(1)利用SRS信道协方差矩阵,包含但不限于以下几种格式:
1)SRS信道协方差矩阵的第一列。
2)SRS信道垂直向协方差矩阵的第一列、SRS信道水平向协方差矩阵的第一列。或者垂直向和水平向可以分开训练检测,之后将检测结果进行并集处理。
3)垂直向协方差矩阵的能量谱,水平向协方差矩阵的能量谱。
4)垂直向协方差矩阵的能量谱,垂直向能量谱的峰值位置,水平向协方差矩阵的能量谱,水平向能量谱的峰值位置。
5)赋形权值向量最大能量方向的垂直向分量的能量谱,赋形权值向量最大能量方向的水平向分量的能量谱。
6)赋形权值向量最大能量方向的垂直向分量的能量谱,垂直向能量谱的峰值位置,赋形权值向量最大能量方向的水平向分量的能量谱,水平向能量谱的峰值位置。
(2)SRS信道协方差矩阵与SINR组合,可学习预测不同覆盖下的空间波束域;
(3)SRS信道协方差矩阵与CQI组合,可学习预测不同覆盖下的空间波束域;
(4)SRS信道协方差矩阵与PMI组合,可提高学习预测准确度;
(5)SRS信道协方差矩阵与DOA组合,可提高学习预测准确度。
二、模型训练模块
基于神经网络的模型训练模块主要分两个阶段:初始训练阶段、迭代训练阶段。其中,
初始训练阶段:将初始预处理好的多维特征集数据分为两部分:训练集和测试集。把训练集输入到神经网络中进行训练,得到合适的模型参数,然后利用测试集进行模型的测试,得到测试结果;不断调整和优化模型参数,一直达到比较满意的测试结果为止,保存训练好的模型参数。
迭代训练阶段:如果未知位置用户的信道数据在线检测出来的归属各个波束域的匹配概率都低于某一个阈值,比如β,那么会被判为新的波束域,保存当前用户的数据,进行模型的重新训练和优化。以此类推,这样不断扩大数据样本集,能够使网络模型不断优化,检测出更多的波束域。
三、在线检测模块
将未知位置的用户的数据,进行同样的数据预处理,获取多维特征集,输入到训练好的神经网络(相当于上述波束域划分模型)中进行在线检测,给出预设匹配概率,概率最大的为最终检测结果,进而可以实时地进行在线检测。
四、反馈优化模块
未知位置的用户数据的检测结果,如果被判别为新的波束域,则对数据进行收集并进行标签处理,将其加入到训练集中,用于迭代训练,优化模型。

为了使本申请的目的、技术方案更加清楚,下面结合具体实施例对本申请做进行详细描述。
实施例1
以NR上行SRS信道为例。
假设NR上行SRS占用32个资源块(Resource Block,简称为RB),2RB绑定,用户端4端口,接收基站天线数为64,正负45度极化,垂直向阵子数N=4,水平向阵子数M=8。多用户位置位于(x=100,y=[-100 100],z=0)范围内。图6是根据本公开实施例的构建的多用户场景示意图(一),(用户在y--100和y-100之间随机分布)。
本实施例进行波束域划分方法采用图3所示的四个阶段:数据初始收集与预处理、模型训练模块、在线检测模块、反馈优化模块。
一、数据初始收集与预处理
数据初始收集与预处理模块包括:数据收集、筛选处理、自动标签处理、数据预处理模 块。
a.数据收集
在初始阶段,收集一段时间的用户数据,本实施例中收集的是基站测量的SRS信道响应和SINR值。
b.筛选处理
本模块的目的主要是去除掉一些异常数据,使得训练样本数据尽可能的是真实有效的用户业务数据。本实施例中,将SINR低于-10dB的数据进行滤除。
c.自动标签处理
根据实际基站的覆盖范围,预置波束域栅格表。一般基站是三扇区覆盖,水平辐射范围为正负60度,下倾角一般在正负15度范围,按照水平和垂直5度的步长进行划分。则二维的预置波束域划分为如图4所示。根据估计出的垂直和水平向角度,判断归属预置波束域栅格的哪个栅格,进行标签的设置,这样训练用户数据与标签就建立起一一对应关系。
本实施例中,根据SRS信道估计值及天线阵列模式,计算垂直向协方差矩阵R v和水平向的协方差矩阵R h。将R v变换到角度域后,在角度域搜索峰值,根据峰值位置计算垂直角度θ。将R h变换到角度域后,在角度域搜索峰值,根据峰值位置计算水平角度

根据估计的用户的垂直和水平角度
Figure PCTCN2022124391-appb-000002
判断其落在哪个栅格的角度范围内,结合预置波束域栅格表,进行标签的设置,这样训练用户数据与标签就建立起一一对应关系。本实施例中,利用的预置波束域栅格里的标签,即图4所示的有底色的数字标号。
d.数据预处理
提取多维数据特征,将数据预处理为机器学习所需要的数据格式。本实施例中,采用的SRS信道协方差矩阵的第一列。
SRS信道协方差矩阵Rx=E[H*H H],其中,H表示SRS信道响应,() H表示共轭转置。则神经网络或聚类算法的输入数据格式为Rx的第一列向量。由于目前应用的机器学习要求输入是实数,且输入值需要归一化,因此构造的输入特征数据格式为:
[real(normRx);imag(normRx)] H
其中,Rx1=Rx(:,1);k mod=max(|Rx1|);normRx=Rx1/k mod;输入特征数据的行数为样本数,列数为特征数。
二、模型训练模块
基于神经网络的学习训练模块主要分两个阶段:初始训练阶段、迭代训练阶段。
初始训练阶段:将初始预处理好的多维特征集数据分为两部分:训练集和测试集。把训练集输入到神经网络中进行训练,得到合适的模型参数,然后利用测试集进行模型的测试,得到测试结果;不断调整和优化模型参数,一直达到比较满意的测试结果为止,保存训练好的模型参数。
迭代训练阶段:如果未知位置用户的信道数据在线检测出来的归属各个波束域的匹配概率都低于某一个阈值,比如β=0.35,那么会被判为新的波束域,保存当前用户的信道数据,进行模型的重新训练和优化。以此类推,这样不断扩大数据样本集,能够使网络模型不断优 化,检测出更多的波束域。
三、在线检测模块
将未知位置的用户的信道数据,进行同样的数据预处理,获取多维特征集,输入到训练好的神经网络中进行在线检测,给出预设匹配概率,概率最大的为最终检测结果。本实施例中,基于神经网络的空间波束域划分预测准确率达95%以上。
四、反馈优化模块
根据未知位置的用户数据的检测结果,如果被判别为新的波束域,则对数据进行收集并进行标签处理,将其加入到训练集中,用于迭代训练,优化模型。
本实施例采用神经网络模型为全链接四层神经网络,一个输入层,两个隐层,一个输出层,采用的优化器是随机梯度下降(Stochastic Gradient Descent,简称为SGD),激活函数是Logistic。图7是根据本公开实施例中采用的全链接神经网络示意图。
实施例2
以NR上行SRS信道为例。
假设NR上行SRS占用104个RB,2RB绑定,用户端4端口,接收基站天线数为64,正负45度极化,垂直向阵子数N=4,水平向阵子数M=8。
图8是根据本公开实施例中构建的多用户场景示意图(二)。基于聚类算法的输入数据特征集也可以有多种,本实施例中采用的是信道协方差矩阵的第一列。
SRS信道协方差矩阵Rx=E[H*H H],其中,H表示SRS信道响应,() H表示共轭转置。由于目前应用的机器学习要求输入是实数,且输入值需要归一化,因此构造的输入特征数据格式为:
[real(normRx);imag(normRx)] H
其中,Rx1=Rx(:,1);k mod=max(|Rx1|);normRx=Rx1/k mod;输入特征数据的行数为样本数,列数为特征数。
本实施例中采用的是sklearn.cluster.KMeans及Bio.Cluste.kcluster模块来实现聚类算法,从而实现不同用户的波束域的划分。图9是根据本公开实施例中基于聚类的波束域划分结果示意图(横轴为样本数,纵轴为标签号,灰度深浅为聚类标识,同一灰度代表同一类,划分准确率为100%)。
另外,聚类方法和基于神经网络的方法可以联合使用,在聚类的先验结果上,进一步利用神经网络进行更精准的波束域划分。
与现有技术相比,本公开的有益效果如下:(1)在无线通信系统中的MU-MIMO技术中,基于机器学习进行空间波束域划分,更贴合实际的多变复杂的环境,有助提高配对成功率。(2)在线检测用户归属波束域,根据检测结果迭代训练检测,不断扩大训练数据集,易于实现,且可提高检测性能。(3)基于空间波束域的划分,空间特性统计,在应用MU-MIMO技术中,有助于降低用户配对复杂度,扩大用户配对选择范围,易选择到最优组合,获得最佳的配对增益。(4)通过对空间波束域的划分,在应用MU-MIMO技术中,有助于降低用户调度复 杂度。(5)本公开提取的多维特征集,易于计算,便于硬件实现。
此外,本申请实施例上述技术方案,可以进行空间波束域划分,对用户进行归属波束域检测,在MU-MIMO技术中,可以应用于多用户配对,多用户调度,提高MU-MIMO传输性能。在SU传输中,有助于最优波束的选择。在定位系统中,可以缩小定位区域,降低定位复杂度。在探测系统或监测系统中,在对目标的跟踪探测中,空间栅格化有助于降低复杂度,提高检测性能。
需要说明的是,本申请实施例在MU-MIMO场景,可以基于机器学习的用户选择、用户调度、多用户扎堆判断;在SU-MIMO场景,会涉及到空间最优波束域选择;在其他场景,比如定位系统中,探测系统中,监测系统中,也会涉及到空间域划分。
