信号调节装置为表面电磁活跃的无线环境,该无线环境的每个部分都可以发射和接收电磁场,如果能够智能地控制这些电磁场,就有可能将能量集中在三维空间中进行传输和接收,提高能力效率并减小干扰。
以智能面板(Intelligent Surface)为例,智能面板又称为智能表面、可配置电磁表面(Reconfigurable Intelligent Surface,RIS)等,通过改变面板中的阵子(Intelligent Surface Element),或者称为可调控电磁单元的电磁特性,可以产生可调的辐射电场,获取所期望的辐射特性,从而能够在发射信号或者反射信号时,实现大规模多进多出(Multiple-In Multiple-Out,MIMO)的波束赋形效果。信号调节装置可以应用于无线通信、无线充电和遥感等不同场景,使得物理环境能够变得“智能”和交互式。理论上可以调控改变的电磁特性包括:相位特征Phase,幅度特征Amplitude,频率特性Frequency,极化特性Polarization,角动量Angular Momentum等等。因为智能面板具备了改变电磁特性的能力,电磁波能够根据我们期望的方式进行控制。
信号调节装置的主要应用是利用其反射效果辅助通信,改善覆盖或增加传输层数,其模型如图1所示。在相关技术中,若想要有效改变信号调节装置每个部分的电磁特性,需要准确获取基站与智能面板之间的信道信息以及智能面板与移动终端之间的信道信息,但是,由于信号调节装置的低成本要求,往往无法通过信号调节装置进行信道测量以得到对应的调控信息,如通过导频反馈测量,测量效率较低。
基于此,本申请实施例第一方面提供的调控方法、信息处理方法、信号调节装置、设备及介质,通过获取指示信息,根据指示信息,确定测量调控参数集合,根据测量调控信息,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量信号调节装置的目标调控信息。本申请实施例通过根据指示信息调控信号调节装置中的电磁单元的电磁特性,有效提高了信号调节装置的调控信息的测量效率。

其中,智能面板120的基本原理是,通过改变智能面板阵子,或者可调控电磁单元的电磁特性,产生可调的辐射电场,获取需要的辐射特性,在发射或者反射时,实现大规模多进多出(Multiple Input Multiple Output,MIMO)的波束赋形效果。理论上可以调控改变的电磁特性包括但不限于:相位特征、幅度特征、频率特性、极化特性和角动量。因为智能面板具备改变电磁特性的能力,使得电磁波能够根据用户期望的方式进行控制、具有非常广泛的应用前景。
需要说明的是,设置在智能面板120的电磁单元121的数量以及排列形式可以根据实际情况设置,本实施例对其不作具体限定。
本领域技术人员可以理解的是,基站110,是移动设备接入互联网的接口设备,也是无线电台站的一种形式,是指在一定的无线电覆盖区中,通过移动通信交换中心,与移动电话终端之间进行信息传递的无线电收发信电台。例如,可以是GSM***或CDMA中的基站(Base Transceiver Station,简称为“BTS”),可以是WCDMA***中的基站(NodeB,NB),可以是LTE***中的演进型基站(Evolutional Node B,eNodeB),可以是5G基站,还可以是后续演进的网络对应的基站。

需要说明的是,当需要对电磁单元的相位进行调整时,Φ为目标调控信息,Φ为与电磁单元维度相关的对角矩阵,对随电磁单元变化的角线元素不相等。智能面板有N个电磁单元,那么目标调控信息Φ的应该是具有N*N个元素的对角矩阵。举例来说,对于电磁单元维度为16*16的智能面板,共有256个电磁单元,目标调控信息Φ可以为256*256对角矩阵。
需要说明的是,根据智能面板能力,智能面板可以包括幅度调整部分和相位调整部分,或者只包含相位调整部分。Φ的维度可以为N×N,可以为N×nt,也可以为nt×r。

参照图2,在一些实施例中,本申请提供一种信息处理方法,应用于第一通信设备,方法包括:

步骤S1200,对目标基础矢量经过第二预设函数处理,得到目标调控信息。
基于前述介绍可以看出,如果获取准确的h2,k,H1,可以根据h2,k,H1确定智能面板上的相位调节矩阵Φ,相关技术的方法是分别测量h2,k,H1,然后基于其计算出最佳的目标调控信息Φ。在本申请一些实施例中,可以对第一信道信息和第二信道信息经过第一预设函数处理得到目标基础矢量,然后通过执行步骤S1200对目标基础矢量经过第二预设函数处理,得到目标调控信息。从而将分别测量h2,k,H1的技术问题转化为测量目标基础矢量的技术问题,由于不需要执行相关技术中的获取第一通信设备与智能面板之间的信道信息以及获取智能面板与第二通信设备之间的信道信息的操作,因此能够避免由于智能面板的低成本要求而导致的无法通过智能面板进行信道信息的测量的问题,从而可以充分发挥智能面板的性能。

在一些实施例中,第一通信设备可以与第二通信设备进行信息交互,以根据第二通信设备的反馈信息获取目标基础矢量以计算第一矢量,其中,第一矢量用于表征第一信道的左奇异矢量信息和第二信道的右奇异矢量信息之间的差异信息,第一信道为第一通信设备和智能面板之间的信道,第二信道为智能面板和第二通信设备之间的信道。具体地,第一通信设备能够与第二通信设备进行信息交互,可以主动向第二通信设备发送信息,也可以被动接收来自第二通信设备处所发送的信息,还可以主要要求第二通信设备发送所需要的信息,如本实施例中,第一通信设备可以获取来自第二通信设备所发送的反馈信息获取目标基础矢量以计算第一矢量,其中,第一矢量用于表征第一信道的左奇异矢量信息和第二信道的右奇异矢量

步骤S1220,根据目标基础矢量、权值系数和第一矢量函数,计算得到第一矢量;
步骤S1230,对第一矢量进行对角化处理得到目标调控信息。
在一些实施例中,第一通信设备可以利用从第二通信设备所获取的反馈信息测量得到目标基础矢量,以计算得到目标调控信息。可以理解的是,目标调控信息可以用于指示智能面板对所接收的信息的相位进行调整处理,或者可以用于指示智能面板对所接收的信息的幅度进行调整处理,或者可以用于指示智能面板对所接收的信息的频率进行调整处理,或者还可以用于指示智能面板对所接收的信息的极化进行调整处理,本实施例对目标调控信息不作具体限定。
在一些实施例中,第一通信设备可以向智能面板发送目标调控信息,使得智能面板根据目标调控信息对智能面板中的电磁单元进行调整。具体地,第一通信设备可以将根据目标基础矢量所得到目标调控信息向智能面板进行发送,以使智能面板根据该目标调控信息对智能面板中的电磁单元进行调整,由于本方案的实施例通过获取能够表征第一通信设备与智能面板之间的信道信息以及智能面板与第二通信设备之间的信道信息的差异信息的第一矢量,然后根据该第一矢量得到能够对智能面板中的电磁单元进行调整的目标调控信息,不需要执行相关技术中的获取第一通信设备与智能面板之间的信道信息以及获取智能面板与第二通信设备之间的信道信息的操作,因此能够避免由于智能面板的低成本要求而导致的无法通过智能面板进行信道信息的测量的问题,从而可以充分发挥智能面板的性能。
需要说明的是,智能面板根据目标调控信息对智能面板中的电磁单元的相位特征、幅度特征、频率特性、极化特性以及角动量等等电磁特性进行调整。
下面以一示例对步骤S1100和步骤S1200的处理过程进行详细说明。
在一些实施例中,可无需测量准确h2,k,H1,而是测量的第一信道的左奇异矢量信息和第二信道的右奇异矢量信息之间的差异信息,再通过差异信息计算得到目标调控信息。
在一些实施例中,可以对第二信道信息h2,k和第一信道信息H1分别进行奇异值分解,即有:
其中,v2,k为第二信道的右奇异矢量信息,u1为第一信道的左奇异矢量信息。
然后通过在一个测量调控参数集合中选择合适的目标调控信息Φ,智能面板根据目标调控信息Φ对电磁单元的相位进行调整可以最小化v2,k和u1两者的距离,从而可以使得智能面板的传输性能最佳。可以通过数学形式对选择合适的目标调控信息Φ的方法进行如下表示:
其中distance表示的是距离函数,其可以采用的数学中的多种距离定义,例如弦距离chord distance。
需要说明的是,第一预设函数可以是包含上述公式(1)、(2)和(3)的函数组;v2,k,u1可以是矢量;也可以是多个矢量张成的子空间(矩阵),本实施例对其不作具体限定。
需要说明的是,对于第一信道信息H1,可以通过第一通信设备(如基站)设置合适的预编码,以将公式(2)中的变成标量(如1),因此对于第一信道信息H1仅需考虑左奇异矢量信息u1。
在一些实施例中,本申请的设计思路是找到一个合适的目标调控信息Φ,使得第二信道信息h2,k的右奇异矢量v2,k,与第一信道信息H1的左奇异矢量u1相适配。原理上,如果我把Φ乘以第一信道信息H1看成是一个整体的话,这个整体越接近v2,k越好。那也就是说,如果我把H1分解之后,然后再在它的左边再乘以Φ,所以技术问题就可以转化成寻找一个比较合适的目标调控信息Φ,可以使v2,k和u1的距离尽可能的最小。因此,本申请实施例想要寻找一个比较合适的目标调控信息Φ,对于两段信道(第一信道和第二信道),本申请实施例不用把两段的信道都测出来,而是转换为要测出把v2,k和u1的差异信息,因为v2,k是u1旋转后要尽量靠近的一个目标(因为u1与目标调控信息Φ的乘积,其实就是对u1做了一个旋转)。
因此本技术方案的信息处理方法无需获取准确的h2,k,H1,只需获取v2,k和u1的差异信息,可以确定较佳的目标调控信息Φ,从而使得智能面板能够达到较佳的传输性能。
接下来说明如何获取v2,k和u1的差异信息。在一些实施例中,对于第二信道信息h2,k的右奇异矢量v2,k和第一信道信息H1的左奇异矢量u1,在数学上转换成目标基础矢量的加权的合并;在物理上,第二信道信息h2,k的右奇异矢量v2,k和第一信道信息H1的左奇异矢量u1实际是第一信道和第二信道形成的一条或多条路径的叠加。即目标基础矢量的数量与第一信道和第二信道形成的路径数量相关。
在一些实施例中,可对第一预设函数的处理过程进行进一步推导以及详细说明:
首先,根据无线信道的特征和天线的拓扑结构,把v2,k和u1分别进行分解处理,能够得到v2,k和u1的累加形式,如下公式所示:
其中,(:,l)表示第l列,和为基础矢量,需要说明的是,基础矢量可以是DFT矢量或者可以是DFT矢量的克罗内克积(Kronecker product)形式,本实施例对其不作具体限定。例如:线性阵列的电磁单元可以选取DFT矢量作为基础矢量;又例如:矩形的面阵可以选择DFT矢量的克罗内克积形式作为基础矢量。公式中和为复数形式的加权系数。
接着,反射面板上的相位调节矩阵可以描述为以下形式:
从相位调节矩阵的公式可以发现,相位调节矩阵(目标调节信息)Φ可以表示成v2,k(:,l),u1(:,l)的哈达玛积(hardamad product)构造的矢量的对角化形式。表示哈达玛积运算,diag表示对N维的矢量进行对角化处理得到一个对角矩阵,其对角线元素为该矢量中的元素。
可以定义矢量然后通过上述分析可以推导得到第一矢量C:
即通过执行步骤S1130,构建用于表征左奇异矢量信息和右奇异矢量信息之间的差异信息的第一矢量函数,在一些实施方式中,公式(7)即为第一矢量函数。
对上述公式进行分析可以发现,目标调节信息Φ可以表示成第一矢量C的对角化,第一矢量C可以表示为的线性合并形式。其中需要说明的是,如果和为DFT矢量或DFT矢量的克罗内克积,那么也为DFT矢量或DFT矢量的克罗内克积。v2,k和u1的差异信息可以表示成的线性合并形式,即当需要反馈v2,k和u1的差异信息时,可以转化为反馈及其线性合并的加权系数信息。因此,可以通过执行步骤S1140,将第一矢量函数对应的DFT矢量作为目标基础矢量,并通过执行步骤S1200,对目标基础矢量经过第二预设函数(第二预设函数可以是根据上述公式(6)得到的对应关系函数)处理,得到目标调控信息Φ。
例如,在一些实施例中,本申请提出的方法,可以将第一矢量设置成DFT矢量(或者多个DFT矢量的克罗内克积形式)的线性合并,以DFT矢量为例,第一矢量可以表示为:
其中Am为预设的加权系数,Xt为一个预设的集合,Am和Xt可以针对每个分别设置,进行联合的测量反馈。需要说明的是,对于不同的t,Xt存在交集。
即在本方案的实施例中,第一通信设备可以获取来自第二通信设备所发送的反馈信息,以得到第一矢量,该第一矢量用于表征第一信道的左奇异矢量信息和第二信道的右奇异矢量信息之间的差异信息,其中,第一信道为第一通信设备和智能面板之间的信道,第二信道为智能面板和第二通信设备之间的信道,然后第一通信设备可以利用第一矢量计算得到目标调控信息,再将目标调控信息向智能面板进行发送,以使智能面板根据该目标调控信息对智能面板中的电磁单元进行调整,由于本方案的实施例通过获取反馈信息,并利用计算能够表征
第一通信设备与智能面板之间的信道信息以及智能面板与第二通信设备之间的信道信息的差异信息的第一矢量,然后根据该第一矢量得到能够对智能面板中的电磁单元进行调整的目标调控信息,不需要执行相关技术中的获取第一通信设备与智能面板之间的信道信息以及获取智能面板与第二通信设备之间的信道信息的操作,因此能够避免由于智能面板的低成本要求而导致的无法通过智能面板进行信道信息的测量的问题,从而可以充分发挥智能面板的性能。
为了得到第一矢量C,需要通过导频测量以得到接下来说明如何测量反馈信息,以得到
如直接发送导频信息测量会导致导频资源开销大(第一通信设备需要发送大量的导频信息),测量效率低的问题。
例如,可设置T个相位调节矩阵(候选调控信息)并将构成一个集合其中,均是由N个矢量(包含候选基础矢量)进行对角化处理所得到。需要说明的是,T和N的数值可以根据应用场景需要进行预设定,本实施例对其不作具体限定。
然后,将构成的一个集合ξrs,其中ξrs由一组完备的DFT矢量或者其克罗内克积构造的矢量组成。
为了从集合中选择出合适的第一矢量,则需要T个导频资源,而每个导频资源采用一种智能面板上的相位调节矩阵,相位调节矩阵分别为接着基于T个导频资源进行测量和反馈,从而选择合适的
即在相关方法中,需要第一通信设备向第二通信设备发送T次导频,然后获取T个导频资源的反馈信息才能够测量出信息。
需要说明的是,中包含的DFT矢量是指矢量中元素模值相同,而且相邻元素的相位差为固定值的一类矢量。例如可以定义DFT矢量为:
需要说明的是,相邻的元素相位都相差一个固定值。
需要说明的是,在公式(9)中,N是DFT矢量的维度,O为过采样因子,例如:当把0至2π分成N份时,过采样因子为1,当把0至2π分成O*N份时,过采样因子为O;M为DFT矢量的索引,表示第m个DFT矢量。那么两个DFT矢量的克罗内克积形式可以表示为:
需要说明的是,DFT矢量的相位变化梯度的取值范围为0至2π,指定一个DFT矢量的维度和相位变化梯度可以确定一个DFT矢量。
需要说明的是,完备DFT矢量集合指的是m的取值为0至(O*N-1);还可以推广到m1和m2的取值情形,即T=O*N,或者是T=O1*O2*N1*N2。
需要说明的是,DFT矢量的相位取值在0~2π之间,是一个有限的集合,DFT矢量的相位取值与电磁单元的方向相关。在一些实施例中,DFT矢量的相位取值在0~2π之间分成多少份取决于***要求的精度。理论上,DFT矢量的相位取值在0~2π之间可以分成无穷多份,此时***精度高;DFT矢量的相位取值在0~2π之间也可以分成较少份数,比如2份或者4
份,此时***精度较低。
在一些实施例中,DFT矢量的相位取值在0~2π之间分成多少份是与电磁单元的数量相关。比如智能面板的水平方向有ND个电磁单元、垂直方向有ND个电磁单元,可对水平方向和垂直方向两个维度独立处理的,最后将水平方向的DFT矢量和垂直方向的DFT矢量做克罗内克积。以水平方向为例,水平方向上ND个电磁单元,则水平方向上DFT矢量的相位取值在0~2π之间需要分成ND*2份,以实现无损分解。例如,智能面板的水平方向有16个电磁单元、垂直方向有16个电磁单元,则DFT矢量的精度在水平方向上需要分成16×2份,在垂直方向上需要分成16×2份,即水平方向上对应有32个导频信息,垂直方向上对应有32个导频信息。这样,对于高频***,电磁单元数量多,如10000个,此时为了实现无损分解和合成,需要发送20000个导频信息,导频开销巨大。
从上述分析可以发现,这种方法在T的取值很大时,存在导频开销需要非常多的问题。例如在高频时智能面板的电磁单元的数量可以达到10000个以上,则需要几万个导频资源,导频开销非常大,并且导频需要在时间上采用不同的符号发送,全部发完才能找到合适目标矢量信息导致工作时会出现很大的延迟。
基于此,本申请实施例提供的调控方法,可通过获取指示信息,根据指示信息,确定测量调控参数集合,根据测量调控信息,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量信号调节装置的目标调控信息。本申请实施例通过根据指示信息调控信号调节装置中的电磁单元的电磁特性,有效提高了信号调节装置的调控信息的测量效率。
请参照图3,一种信号调节装置的调控方法,应用于信号调节装置,调控方法包括:
步骤S2100,获取指示信息;
步骤S2200,根据指示信息,确定测量调控参数集合,其中,测量调控参数集合包括多个信号调节装置的测量调控信息;
步骤S2300,根据测量调控信息,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量信号调节装置的目标调控信息。
在一些实施例中,可以将第一矢量设置成DFT矢量(或者多个DFT矢量的克罗内克积形式)的线性合并,以DFT矢量为例,第一矢量可以表示为:
其中Am为预设的加权系数,Xt为一个预设的集合,Am和Xt可以针对每个分别设置,进行联合的测量反馈。
需要说明的是,对于不同的t,Xt存在交集。
假设Am=1,即先测量选择目标基础矢量后再进行加权测量。实际操作中,可通过发送导频信息和获取反馈信息以获取的信息。在本实施的技术方案中,信号调节装置通过执行步骤S1100至步骤S1300,发送导频信息对第二通信设备进行测量,即使只包含一个DFT矢量分量,那么多个导频信息的测量结果中也会有多个测量结果是可以测量到不弱的接收功率。即本申请实施例根据测量调控参数集合对导频信息做预编码,如果第一矢量包含该测量调控参数集合中对应的DFT矢量,则接收端(第二通
信设备)应该能测到质量还不错的接收功率,因此,可利用指示信息合理配置测量调控参数集合,实现节省导频信息发送次数。相对于在相关技术中,如果的成分是稀疏的,则在T次测量中,能够收到不弱的接收功率的导频也是非常稀疏的,这实际上是对导频资源的一种浪费。而在智能面板应用中,一般来说智能面板的电磁单元(或称为阵元、阵子)数目较多,而且常用于高频情况,在高频情况下波长较短,可以部署更多的阵元,对于这种表征信道信息的其成分都是稀疏的,所以采用本实施的技术方案的方法,其导频利用率会更高。
需要说明的是,本申请实施例中并没有降低表示第一矢量的DFT矢量的个数,而是在反馈的时候通过“分组”的方式减少反馈时用到的导频数量。例如,如第一矢量中只包含16个DFT矢量(候选基础矢量)中的一个,相关技术中需要发送16次导频信息才能测试出第一矢量包含的是哪个DFT矢量,而采用本申请实施例“分组”后通过4次导频就能测试出第一矢量中包含的是哪个DFT矢量,提高了测量效率。并且,第一矢量中包含的DFT矢量越稀疏(越少),本申请实施例提高测量效率的效果越明显。
需要说明的是,步骤S2100至步骤S2300可以在智能面板的控制器中实现。步骤S2100中,信号调节装置可以获取来自外部设备的指示信息,例如,可以是来自第一通信设备(如基站)的指示信息,也可以是来自第二通信设备(如用户终端)的指示信息。显然的,外部设备也可以时其他网元,本申请实施例对此不作限定。
在一些实施例中,目标调控信息包括目标基础矢量。每一测量调控参数集合中的多个测量调控信息包含不同的候选基础矢量或不同的候选基础矢量组合;
对应的,步骤S2300,根据测量调控信息,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量信号调节装置的目标调控信息,包括:
步骤S2310,根据测量调控信息,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量并根据测量结果在多个候选基础矢量中确定至少一个目标基础矢量。
在一些实施例中,即本申请实施例根据测量调控参数集合对导频信息做预编码,如果第一矢量包含该测量调控参数集合中对应的DFT矢量,则接收端(第二通信设备)应该能测到质量还不错的接收功率,接收端将是否收到导频信息的反馈信息传输给第一通信设备,第一通信设备可根据接收到的反馈信息计算得到对应的DFT矢量,并将其作为第一矢量包含的目标基础矢量。可通过指示信息合理配置测量调控参数集合,实现节省导频信息发送次数。
在一些实施例中,测量调控参数集合可以是预存在信号调节装置中的,也可以是信号调节装置根据指示信息自动生成的。
在一些实施例中,信号调节装置预存有多个测量调控参数集合每个包括多个信号调节装置的测量调控信息例如多个调控参数集合分别为:
……
每个调控参数集合均为预设设置好的图样,对应一定的测试模型。第一通信设备发射导频信息,信号调节装置根据对应的调控参数集合反射导频信息到第二通信设备,第二通信设备将对导频信息的接收状态反馈到第一通信设备,第一通信设备再根据预设的图样对应计算出对应的目标基础矢量。在一些实施例中,测量调控参数集合是由第一通信设备发送给信号调节装置以存储在信号调节装置中的。
在一些实施例中,信号调节装置预存有多个测量调控参数集合,指示信息用于直接指示测量调控参数集合的索引信息;
对应的,根据指示信息,确定测量调控参数集合包括:
步骤S2210,根据指示信息,确定测量调控参数集合的索引信息;
步骤S2220,根据索引信息,从预存的多个测量调控参数集合中,确定对应的测量调控参数集合。
在一实施例中,智能面板保存有多个调控参数集合每个包括多个信号调节装置的测量调控信息例如多个调控参数集合分别为:
……
指示信息包括用于直接指示测量调控参数集合的索引信息。信号调节装置(如智能面板)接收到指示信息后,根据指示信息中索引信息找到预存的对应的测量调控参数集合。即是说,信号调节装置通过指示信息提前知道目标调控信息只存在于索引信息对应的调控参数集合中,相对于发送全部测量调控信息,可节省大量导频资源。
在一些实施例中,信号调节装置预存有多个测量调控参数集合和预设的对应关系表;
指示信息包括基础矢量先验信息,对应关系表包括基础矢量先验信息与多个测量调控参数集合的对应关系;
对应的,步骤S2200,根据指示信息,确定测量调控参数集合包括:
步骤S2230,根据基础矢量先验信息,查询对应关系表以确定对应的测量调控参数集合。
在一实施例中,智能面板保存有多个调控参数集合每个包括多个信号调节装置的测量调控信息例如多个调控参数集合分别为:
……
在一些实施例中,指示信息包括基础矢量先验信息,基础矢量先验信息可包括矢量数目
和/或矢量分布范围等,其中,矢量数目用于表征候选基础矢量的数量或数量范围,矢量分布范围用于表征候选基础矢量的分布范围。
具体的,例如基础矢量先验信息可包括矢量数目,即第一通信设备/第二通信设备可以通知信号调节装置目标基础矢量的矢量数目(数量),具体通知形式不限。矢量数目能够让信号调节装置知道我的到导频应该发多少个、如何发。例如,根据第一通信设备与信号调节装置的约定,矢量数目为1对应表示多径的数量只有一个,也就是目标基础矢量只有一个,则信号调节装置只发送目标基础矢量为1对应的调控参数集合即可,无需发送全部的测量调控信息。又如,基础矢量先验信息可包括矢量分布范围,根据前文可知,DFT矢量的相位分布范围是0到2π,在一些实施例中,DFT矢量的相位分布范围可能是更小的范围,例如0~2/π,这样信号调节装置无需发送全部矢量,只需发送匹配0~2/π相位分布范围的调控参数集合即可,无需发送全部的测量调控信息。
需要说明的是,第一矢量中含有的DFT矢量的数量(矢量数目)与信道路径的数量相关。在一些实施例中,DFT矢量的数量(矢量数目)与信道路径是一一对应的。例如,第一矢量中含有的DFT矢量的数量(矢量数目)为1,则信道路径的数量也为1(如只有一个LOS径);DFT矢量的数量(矢量数目)为2,则信道路径的数量也为2(如有一个LOS径和一个NLOS径(反射径))。
例如,智能面板可以根据矢量数目或矢量分布范围等先验信息从表二中确定调控参数集合
表二
由表二可知,当指示信息中包含指令基础矢量数目为1、基础矢量分布范围为2,则信号调节装置测量过程中对应发送的调控参数集合为以此类推。
在一些实施例中,指示信息包括基础矢量先验信息;
对应的,步骤S2200,根据指示信息,确定测量调控参数集合,包括:
步骤S2240,根据基础矢量先验信息,按照第一预设规则生成测量调控参数集合。
在一些实施例中,测量调控参数集合也可以是信号调节装置根据指示信息自动生成的。例如,信号调节装置可以预存测量调控参数集合的生成方法,根据基础矢量先验信息(如矢量数目和/或矢量分布范围等),生成对应的测量调控参数集合。
在一些实施例中,基础矢量先验信息包括矢量数目或矢量分布范围中的至少一个,其中,矢量数目用于表征候选基础矢量的数量或数量范围,矢量分布范围用于表征候选基础矢量的分布范围。第一预设规则包括:
测量调控参数集合中的测量调控信息的数量为N满足:
其中,Q为第二通信设备响应于导频信息的反馈信息的比特数,M为候选基础矢量的组合的可能性的数量。
如前述,每个调控参数集合均为预设设置好的图样,对应一定的测试模型。图样的设计可以根据所需的情况对应的分辨率设计。
以候选DFT矢量(候选基础矢量)总共有16个(如DFT矢量在0-2π之间被分为16份)为例,当矢量数目为1或2,即对应的图样需要包含矢量数目为1或2的所有测量调控信息。当矢量数目为1,即需要在16个DFT矢量中挑选1个作为目标基础矢量,包含的可能组合情况有种;当矢量数目为2,即需要在16个DFT矢量中挑选2个作为目标基础矢量,包含的可能组合情况有种;包含矢量数目为1或2的所有测量调控信息的组合情况M=16+120=136种。即是说,理论上发送导频信息的次数N(测量调控信息的数量N)需要能够覆盖136种情况。当反馈信息的比特数Q为1时,由于一个比特可表示两种状态,2的7次方为128,小于136,2的8次方为256,大于136,因此对应N可以取8,即测量调控信息的数量为N=8,发送8次导频信息即可满足测试得到目标基础矢量的要求,而无需发送136次导频信息。在另一些实施例中,如果可以确定136种情况种某一些情况时不可能出现的,可以排除掉,从而把包含矢量数目为1或2的所有测量调控信息的组合情况M控制在128种情况以内,则可以通过7次导频信息即可满足测试得到目标基础矢量的要求,即测量调控信息的数量为N=7。可以通过图样和先验信息(指示信息)的配合设计,实现减少测量调控信息的数量,从而减少发送导频的次数。此时,要求第二通信设备在导频信息的测量时间点,无论有没有接收到信号,都需要发送反馈信息给到第一通信设备。
在一些实施例中,当反馈信息的比特数Q为大于等于2的正整数时,由于反馈信息可以表示的状态有多个,这样需要的导频信息发送次数就更少了。例如,当Q为4时,测量调控信息的数量为N只需要满足即可,可实现更节约的导频开销。
在一些实施例中,反馈信息的比特数Q为1,反馈信息用于表征是否接收到导频信息;即1bit信息表征“是”或者“否”。
或者,
反馈信息为多比特,即Q为大于等于2的正整数,反馈信息可用于表征以下的一种或多种信息:是否接收到导频信息、接收到的导频信息的信号强度、接收到的导频信息的相位等。
在一些实施例中,第一矢量中包含的DFT矢量越稀疏(越少),本申请实施例提高测量效率的效果越明显。如前文,对于固定电磁单元数量的智能面板,决定了DFT矢量划分的精度,而DFT矢量划分的精度确定后,发送导频的数量取决于第一矢量中包含的DFT矢量的数量。例如,对于精度为16(如DFT矢量在0-2π之间被分为16份)的***,如果指示信息可确定包含的DFT矢量为1个,则可发送4个到导频信息可以确定该DFT矢量;如果指示信息可确定包含的DFT矢量为2个,则可发送8个到导频信息可以确定该DFT矢量。对于有1000个电磁单元的智能面板,如果指示信息可确定包含的DFT矢量为1个(此时对应的物理环境时路径数量为1,如第一通信设备和第二通信设备之间只有一条LOS径)当本来需要发送2000个导频信息,按本申请实施例的方法,可以发送11个导频信息即可,可大幅度减少导频开销,提高测量效率。
在一些实施例中,每一测量调控参数集合中的多个测量调控信息包含不同的候选基础矢量的线性合并组合。
在一些实施例中,本申请实施例根据测量调控信息包含不同的候选基础矢量的线性合并组合对导频信息做预编码,如果第一矢量包含该线性合并组合中对应的DFT矢量,则接收端(第二通信设备)应该能测到质量还不错的接收功率。每个调控参数集合均为预设设置好的图样指的是设计多个测量调控信息包含不同的候选基础矢量的线性合并组合,使得这些组合对应的反馈信息可以确定第一矢量中包含的DFT矢量。
在一些实施例中,每一测量调控参数集合中的测量调控信息的数量为N满足:
其中,Q为第二通信设备响应于导频信息的反馈信息的比特数,M为候选基础矢量的线性合并组合的可能性的数量。
测量调控信息的数量为N设计的方法如前述,在此不作赘述。
在一实施例中,参照图4,为预设设置好的图样,假设已知是非常稀疏的,且只包含1个DFT矢量(目标矢量信息),但具体的DFT矢量(目标矢量信息)是未知的。图4中的黑色方格表示DFT矢量(候选矢量信息)属于Xt集合(编号顺序从右向左),比如C1包括索引为1/2/3/5/9/10/11/15的DFT矢量(候选矢量信息)的线性合并组合,C2包括索引为1/2/4/5/7/8/11/14的DFT矢量(候选矢量信息)的线性合并组合,C3包括索引为1/3/4/5/6/8/10/13的DFT矢量(候选矢量信息)的线性合并组合,C4包括索引为1/2/3/4/6/7/9/12的DFT矢量(候选矢量信息)的线性合并组合。针对每个会有一个对应的基于其可以测量到一个接收功率的强度值的情况下。第二通信设备反馈有测量到信号或者没有测量到信号,第一通信设备会接收到4个导频的测量结果,通过这4个测量结果的状态,可以反推出所包含的是1个DFT矢量(目标矢量信息),且确定包含的目标矢量信息是哪一个。
示例性的,如图4预设设置好的图样,其中:
目标矢量信息包含DFT1时,其接收状态为C1、C2、C3、C4均收到信号,其它为0;
包含DFT2时,其接收状态为C1、C2、C4收到信号,其它为0;
包含DFT3时,其接收状态为C1、C3、C4收到信号,其它为0;
包含DFT4时,其接收状态为C2、C3、C4收到信号,其它为0;
包含DFT5时,其接收状态为C1、C2、C3收到信号,其它为0;
包含DFT6时,其接收状态为C3、C4收到信号,其它为0;
包含DFT7时,其接收状态为C2、C4收到信号,其它为0;
包含DFT8时,其接收状态为C2、C3收到信号,其它为0;
包含DFT9时,其接收状态为C1、C4收到信号,其它为0;
包含DFT10时,其接收状态为C1、C3收到信号,其它为0;
包含DFT11时,其接收状态为C1、C2收到信号,其它为0;
包含DFT12时,其接收状态为C4收到信号,其它为0;
包含DFT13时,其接收状态为C3收到信号,其它为0;
包含DFT14时,其接收状态为C2收到信号,其它为0;
包含DFT15时,其接收状态为C1收到信号,其它为0;
包含DFT16时,其接收状态为C1、C2、C3、C4均收到不到信号,或者说收到的信号均为0。
在一实施例中,参照图5,假设已知的包含2个DFT矢量(目标矢量信息)的线性组合,此时需要发送8个测量导频,针对每个会有一个对应的基于其可以测量到一个接收功率的强度值的情况下。第二通信设备反馈有测量到信号或者没有测量到信号,第一通信设备会接收到8个导频的测量结果,第一通信设备通过8个测量结果的状态可以反推出所包含的是2个DFT矢量(目标矢量信息)。
示例性的,如图5预设设置好的图样,其中,目标矢量信息包含DFT1和DFT2时,其接收状态为C1和C2收到信号,其它为0;包含DFT1和DFT3时,其接收状态为C1、C3收到信号,其它为0;包含DFT2和DFT3时,其接收状态为C1、C2、C3收到信号,其它为0;包含DFT1和DFT4时,其接收状态为C1、C2、C4收到信号,其它为0;包含DFT2和DFT4时,其接收状态为C2、C4收到信号,其它为0;包含DFT1和DFT5时,其接收状态为C1、C3、C4收到信号,其它为0;包含DFT4和DFT5时,其接收状态为C1、C2、C5收到信号,其它为0;包含DFT2和DFT5时,其接收状态为C1、C2、C3、C5收到信号,其它为0;以此类推。
在一些实施例中,参照前述公式(8),第一矢量可能是由多个DFT矢量合成的,需要进一步测量各DFT矢量合成对应的权值系数(加权系数)。可以在前述测量得到目标基础矢量后,在测量权值系数,这样会更准确。
在一些实施例中,目标调控信息还包括权值系数;
在一些实施例,步骤S2300中,根据测量调控信息,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量信号调节装置的目标调控信息,还包括:
步骤S2320,根据至少一个目标基础矢量,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量至少一个目标基础矢量对应的权值系数(加权系数)。
在一些实施例中,参照前述公式(8),在通过执行步骤S2310测量得到目标基础矢量后,可以进一步通过执行步骤S2320得到加权系数Am,以进一步计算得到第一矢量通常,计算第一矢量的步骤是在第一通信设备中执行。
在一些实施例中,步骤S2320,根据基础矢量,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量至少一个目标基础矢量对应的权值系数,包括:
步骤S2321,接收来自第一通信设备发送的至少一个目标基础矢量,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量至少一个目标基础矢量对应的权值系数。
在一些实施例中,第一通信设备通过前述方法测量得到目标基础矢量后,可以将目标基础矢量发送给信号调节装置,以使信号调节装置根据目标基础矢量调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,第二通信设备接收到导频信息后,将反馈信息发送给第一通信设备,以使第一通信设备测量该目标基础矢量对应的权

举例来说,总共有16个候选基础矢量,通过前述方法测量得到第5个DFT矢量和第10个DFT矢量为目标基础矢量。此时,可在第5个DFT矢量和第10个DFT矢量对应的波束上发送导频信息,当第二通信设备接收到导频信息后,将反馈信息发送给第一通信设备,以使第一通信设备根据反馈信息计算这两个目标基础矢量对应的权值系数。例如,可将反馈信息的信号强度作为权值系数。
需要说明的是,当只有一个目标基础矢量,则不需要测量加权系数,因为此时对应的第一矢量不是基础矢量的线性合并。
本申请实施例提供的调控方法,通过获取指示信息,根据指示信息,确定测量调控参数集合,根据测量调控信息,调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,以测量信号调节装置的目标调控信息。本申请实施例通过根据指示信息调控信号调节装置中的电磁单元的电磁特性,有效提高了信号调节装置的调控信息的测量效率。

请参照图7,在一些实施例中,步骤S3100,响应于信号调节装置发送的导频信息,发送反馈信息到第一通信设备,以测量信号调节装置的目标调控信息之前,还包括:
步骤S3200,接收来自第一通信设备的模式切换指令;
步骤S3300,根据模式切换指令进入测量状态,测量状态为:对导频信息均生成反馈信息,并发送反馈信息到第一通信设备。
在一些实施例中,由于第二通信设备在测量目标调控信息过程中,需要保持对导频信息的全反馈,增加第二通信设备的资源(如能耗资源、计算资源等)开销,因此,可通过模式切换指令对第二通信设备的反馈状态进行切换,即只有接收到切换指令,才进入到测量状态,以节省第二终端的资源开销。模式切换指令可以是来自第一通信设备的,也可以时来自其他
设备,本申请实施例对此不作限定。
请参照图8,在一些实施例中,步骤S3100,响应于信号调节装置发送的导频信息,发送反馈信息到第一通信设备,以测量信号调节装置的目标调控信息之前,还包括:
步骤S3400,发送指示信息到信号调节装置,以使信号调节装置确定测量调控参数集合。

本申请实施例提供的信息处理方法,通过在测量状态下,响应于信号调节装置发送的导频信息,发送反馈信息到第一通信设备,以测量信号调节装置的目标调控信息;其中,导频信息是信号调节装置通过执行如前述的信号调节装置的调控方法发送的。本申请实施例通过根据指示信息调控信号调节装置中的电磁单元的电磁特性,有效提高了信号调节装置的调控信息的测量效率。
另外,请参照图9,本申请实施例还提供一种信息处理方法,应用于第一通信设备,方法包括:
步骤S4100,发送导频信息,使得信号调节装置通过执行如前述的信号调节装置的调控方法反射导频信息到第二通信设备;例如,信号调节装置通过执行如前述步骤S2100至步骤S2300反射导频信息到第二通信设备;
步骤S4200,获取来自第二通信设备的反馈信息;
步骤S4300,根据反馈信息、测量调控参数集合及测量调控参数集合的设置图样,计算得到目标调控信息。
在一些实施例中,第一通信设备可以是基站,也可以是其他具有网络服务功能的设备,本申请实施例对此不作限定。本领域技术人员可以理解的是,基站是移动设备接入互联网的接口设备,也是无线电台站的一种形式,是指在一定的无线电覆盖区中,通过移动通信交换中心,与移动电话终端之间进行信息传递的无线电收发信电台。例如,可以是GSM***或CDMA中的基站(Base Transceiver Station,简称为“BTS”),可以是WCDMA***中的基站(NodeB,NB),可以是LTE***中的演进型基站(Evolutional Node B,eNodeB),可以是5G基站,还可以是后续演进的网络对应的基站。
在一些实施例中,第一通信设备发射导频信息,信号调节装置根据指示信息对应的调控参数集合反射导频信息到第二通信设备,第二通信设备响应于导频信息,将导频信息的接收状态通过反馈信息反馈到第一通信设备,第一通信设备再根据预设的图样对应计算出对应的目标基础矢量。第二通信设备在导频信息发送的时间点,无论第二通信设备有没有收到导频信息,均需要发送反馈信息给到第二通信设备。
在一些实施例中,步骤S4300,第一通信设备需要知道测量调控参数集合及测量调控参数集合的设置图样,才能根据接收到的来自第二通信设备的反馈信息,计算得到目标调控信息。
在一些实施例中,测量调控参数集合的设置图样可根据前述信号调节装置的调控方法中描述的图样设计方式生成,即使得每个调控参数集合均为预设设置好的图样,对应一定的测试模型。图样的设计可以根据所需的情况对应的分辨率设计,在此不作赘述。
在一些实施例中,测量调控参数集合是由第一通信设备发送给信号调节装置以存储在信
号调节装置中的。
在一些实施例中,目标调控信息包括目标基础矢量;测量调控参数集合中的多个测量调控信息包含不同的候选基础矢量或不同的候选基础矢量组合;

步骤S4310,根据反馈信息、测量调控参数集合及测量调控参数集合的设置图样,在多个候选基础矢量中确定至少一个目标基础矢量。
在一些实施例中,可以将第一矢量设置成DFT矢量(或者多个DFT矢量的克罗内克积形式)的线性合并,以DFT矢量为例,第一矢量可以表示为:
其中Am为预设的加权系数,Xt为一个预设的集合,Am和Xt可以针对每个分别设置,进行联合的测量反馈。
需要说明的是,对于不同的t,Xt存在交集。
假设Am=1,即先测量选择目标基础矢量后再进行加权测量。实际操作中,第一通信设备可通过发送导频信息和获取反馈信息以获取的信息。在本实施的技术方案中,信号调节装置通过执行前述步骤S1100至步骤S1300,反射导频信息对第二通信设备进行测量,即使只包含一个DFT矢量分量,那么多个导频信息的测量结果中也会有多个测量结果是可以测量到不弱的接收功率,第二通信设备在导频信息发送对应的时间点返回反馈信息给到第一通信设备。即本申请实施例根据测量调控参数集合对导频信息做预编码,如果第一矢量包含该测量调控参数集合中对应的DFT矢量,则接收端(第二通信设备)应该能测到质量还不错的接收功率,因此,第一通信设备可利用指示信息合理配置信号调节装置的测量调控参数集合,再根据述反馈信息、测量调控参数集合及测量调控参数集合的设置图样,在多个候选基础矢量中确定至少一个目标基础矢量。
请参照图10,在一些实施例中,步骤S4100,发送导频信息之前,还包括:

在一些实施例中,第一通信设备可以用于发送指示信息到信号调节装置,以使信号调节装置执行前述步骤以确定测量调控参数集合。例如,信号调节装置执行前述步骤S2100和步骤S2200以确定测量调控参数集合。
在一些实施例中,目标调控信息还包括权值系数;
对应的,根据反馈信息、测量调控参数集合及测量调控参数集合的设置图样,计算得到目标调控信息,还包括:
步骤S4311,发送导频信息,以使信号调节装置根据至少一个目标基础矢量,调控信号调节装置中的电磁单元的电磁特性,反射导频信息到第二通信设备;
步骤S4312,接收来自终端的反馈信息;
步骤S4313,根据反馈信息,计算至少一个目标基础矢量对应的权值系数。

步骤S4314,发送至少一个目标基础矢量到信号调节装置。
在一些实施例中,第一通信设备通过前述方法测量得到目标基础矢量后,可以将目标基础矢量发送给信号调节装置,以使信号调节装置根据目标基础矢量调控信号调节装置中的电磁单元的电磁特性,以使电磁单元反射导频信息到第二通信设备,第二通信设备接收到导频信息后,将反馈信息发送给第一通信设备,以使第一通信设备测量该目标基础矢量对应的权值系数。需要说明的是,测量权值系数过程中,反馈信息通常应当包含更为具体的信息,如接收的信号强度信息、相位信息等等。
举例来说,总共有16个候选基础矢量,通过前述方法测量得到第5个DFT矢量和第10个DFT矢量为目标基础矢量,第一通信设备可以发送两个目标基础矢量到信号调节装置。此时,第一通信设备发送导频信息,信号调节装置可根据目标基础矢量调控信号调节装置中的电磁单元的电磁特性,反射导频信息到第二通信设备,以实现在第5个DFT矢量和第10个DFT矢量对应的波束上发送导频信息。当第二通信设备接收到导频信息后,将反馈信息发送给第一通信设备,以使第一通信设备根据反馈信息计算这两个目标基础矢量对应的权值系数。例如,可将反馈信息的信号强度作为权值系数。
需要说明的是,当只有一个目标基础矢量,则不需要测量加权系数,因为此时对应的第一矢量不是基础矢量的线性合并。
在一些实施例中,参照前述公式(8),第一矢量可能是由多个DFT矢量合成的,需要进一步测量各DFT矢量合成对应的权值系数(加权系数)。可以在前述测量得到目标基础矢量后,再测量权值系数,这样会更准确。
在一些实施例中,参照前述公式(8),在通过执行步骤S4310测量得到目标基础矢量后,可以进一步通过执行步骤S4311至4313得到加权系数Am,以进一步计算得到第一矢量通常,计算第一矢量的步骤是在第一通信设备中执行。
