下面参考附图对本公开实施例所提供的波束确定方法、装置、设备及存储介质进行详细描述。
图2为本公开实施例所提供的一种波束确定方法的流程示意图，该方法由基站执行，如图2所示，该波束确定方法可以包括以下步骤：
步骤201、接收至少一个终端设备上报的第一波束相关信息，该第一波束相关信息为终端设备与中继设备之间波束对应的相关信息。
本公开的方法可以应用于多用户场景(即多终端设备场景)中。其中，假设当前通信场景下存在有三个终端设备，分别为终端设备#1、终端设备#2、终端设备#3，则基站会接收到终端设备#1上报的第一波束相关信息、终端设备#2上报的第一波束相关信息以及终端设备#3上报的第一波束相关信息；其中，终端设备#1上报的第一波束相关信息具体为：终端设备#1与中继设备之间波束对应的相关信息；终端设备#2上报的第一波束相关信息具体为：终端设备#2与中继设备之间波束对应的相关信息；终端设备#3上报的第一波束相关信息具体为：终端设备#3与中继设备之间波束对应的相关信息。
以及，在本公开的一个实施例之中，上述第一波束相关信息可以指示以下至少之一：
终端设备与中继设备之间波束的波束方向；
终端设备与中继设备之间波束的波束质量。
该第一波束相关信息可以包括以下至少之一：
第一预编码矩阵标识(Precoding Matrix Indicator，PMI)，其中，所述第一PMI为所述终端设备与中继设备之间波束所对应的PMI；
第一PMI对应波束的质量指示信息；
所述终端设备与中继设备之间的波束所对应的波束测量信息，其中，所述波束测量信息包括波束测量参考信号的资源标识ID和/或波束测量参考信号对应的波束质量测量量。
具体的，在本公开的一个实施例之中，该第一波束相关信息可以包括：第一PMI和/或第一PMI对应波束的质量指示信息。其中，该第一PMI为：终端设备与中继设备之间波束所对应的PMI；该第一PMI可以指示终端设备与中继设备之间波束的波束方向；该第一PMI对应波束的质量指示信息可以指示终端设备与中继设备之间波束的波束质量；该第一PMI对应波束的质量指示信息可以包括以下至少一种：
第一PMI对应波束的参考信号接收功率(Reference Signal Receiving Power，RSRP)；
第一PMI对应波束的信噪比(Signal to Interference plus Noise Ratio，SINR)；
第一PMI对应波束的参考信号接收质量(Reference Signal Receiving Quality，RSRQ)；
第一PMI对应波束的接收信号强度指示(Received Signal Strength Indication，RSSI)。
或者，在本公开的另一个实施例之中，该第一波束相关信息可以包括：终端设备与中继设备之间波束所对应的波束测量信息；该波束测量信息可以包括：波束测量参考信号的资源标识(dentity，ID)和/或波束测量参考信号对应的波束质量测量量。其中，该波束测量参考信号的资源ID可以指示终端设备与中继设备之间波束的波束方向；该波束测量参考信号对应的波束质量测量量可以指示终端设备与中继设备之间波束的波束质量；该波束质量测量量可以包括RSRP、RSRQ、SINR、RSSI中的至少一种。
应当理解，第一波束相关信息可以包括第一PMI、第一PMI对应波束的质量指示信息、终端设备与中继设备之间波束所对应的波束测量信息中的一个或多个。并且其他波束相关信息也是可能的，本公开对此不作限制。
步骤202、基于第一波束相关信息获取波束确定信息，该波束确定信息用于确定目标波束，该目标波束为：中继设备向至少一个终端设备进行中继转发时所使用的波束。
其中，在本公开的一个实施例之中，上述的基于第一波束相关信息获取波束确定信息可以包括以下步骤：
步骤a、基于至少一个终端设备的第一波束相关信息确定至少一个终端设备与中继设备之间波束对 应的第一波束方向信息。
在本公开的一个实施例之中，该终端设备与中继设备之间波束对应的第一波束方向信息，包括：
终端设备与中继设备之间波束的第一维度角度值，该第一维度角度值为：终端设备与中继设备之间波束在第一维度上相对于参考方向的角度值；以及
终端设备与中继设备之间波束的第二维度角度值，该第二维度角度值为：终端设备与中继设备之间波束在第二维度上相对于参考方向的角度值。
其中，上述的第一维度与第二维度可以相互垂直，如第一维度可以为水平维，第二维度可以为垂直维。或者，如第一维度可以为竖直维，第二维度可以为水平维。以及，上述的参考方向例如可以是中继设备反射面的法线方向。然而，两个维度的其他位置关系也是可能的。
需要说明的是，上述确定出的终端设备与中继设备之间波束的第一维度角度值、第二维度角度值主要用于后续确定目标波束的波束方向。其中，由于在三维空间中，用两个维度的方向角就能确定出波束方向，因此本公开中仅确定出了第一维度角度值和第二维度角度值。但是，应当理解，本公开中的通过确定两个维度的角度值来确定目标波束的波束方向仅是一种示例，其他的通过确定多个维度(如三个维度的)的角度值来确定目标波束的波束方向也是可能的，本公开对此不作限制。
步骤b、针对至少一个终端设备分别设置第一加权值和第二加权值。
其中，在本公开的一个实施例之中，所述第一加权值和第二加权值均大于等于0且小于等于1，且所有终端设备的第一加权值相加之和为1，所有终端设备的第二加权值相加之和为1。
以及，在本公开的一个实施例之中，上述针对至少一个终端设备分别设置第一加权值和第二加权值可以包括：基于至少一个终端设备上报的第一波束相关信息来针对至少一个终端设备分别设置第一加权值和第二加权值；其中，所述终端设备上报的第一波束相关信息所指示的质量与所述终端设备的第一加权值和第二加权值呈正相关。也即是，当终端设备上报的第一波束相关信息所指示的质量越高(如终端设备上报的第一PMI对应波束的质量指示信息所指示的质量和/或终端设备上报的波束测量参考信号对应的波束质量测量量所指示的质量越高)时，为该终端设备设置的第一加权值和第二加权值越大。
示例的，假设当前通信场景中包括三个终端设备，分别为终端设备#1、终端设备#2、终端设备#3。且三个终端设备上报的第一波束相关信息均为第一PMI和第一PMI对应波束的质量指示信息；其中，若终端设备#1上报的第一PMI对应波束的质量指示信息所指示的质量高于终端设备#3上报的第一PMI对应波束的质量指示信息所指示的质量且高于终端设备#2上报的第一PMI对应波束的质量指示信息所指示的质量。则基站为终端设备#1设置的第一加权值应当大于为终端设备#3设置的第一加权值且大于为终端设备#2设置的第一加权值；以及，基站为终端设备#1设置的第二加权值应当大于为终端设备#3设置的第二加权值且大于为终端设备#2设置的第二加权值，例如，为终端设备#1、终端设备#2、终端设备#3设置的第一加权值可以分别为：0.5、0.2、0.3；为终端设备#1、终端设备#2、终端设备#3设置的第二加权值可以分别为：0.6、0.15、0.25。应理解，满足上述大小关系的其他第一加权值、第二加权值也是可能的。
或者，在本公开的另一个实施例之中，上述针对至少一个终端设备分别设置第一加权值和第二加权值可以包括：将上报的第一波束相关信息中所指示的质量最高的第一波束相关信息所对应的终端设备的第一加权值和第二加权值设置为1(如将上报的第一PMI对应波束的质量指示信息中所指示的质量最高的终端设备和/或上报的波束测量参考信号对应的波束质量测量量所指示的质量最高的终端设备的第一加权值和第二加权值设置为1)，其他终端设备的第一加权值和第二加权值设置为0。
示例的，假设当前通信场景中包括三个终端设备，分别为终端设备#1、终端设备#2、终端设备#3。且三个终端设备上报的第一波束相关信息均为第一PMI和第一PMI对应波束的质量指示信息；其中，若终端设备#1上报的第一PMI对应波束的质量指示信息所指示的质量高于终端设备#3上报的第一PMI对应波束的质量指示信息所指示的质量且高于终端设备#2上报的第一PMI对应波束的质量指示信息所指示的质量。则可以确定出终端设备#1与中继设备之间的波束的质量最高，此时基站为终端设备#1设置的第一加权值和第二加权值均可以为1，而为终端设备#2和终端设备#3设置的第一加权值和第二加权值可以均为0。
需要说明的是，在本公开的一个实施例之中，若当前通信场景仅包括一个终端设备，而不存在其他终端设备(即其他终端的数目为0)时，则上述步骤a中基站可以直接将该一个终端设备与中继设备之间波束的第一维度角度值、第二维度角度值确定为第一波束方向信息；以及，直接将该一个终端设备的第一加权值和第二加权值设置为1。
步骤c、将至少一个终端设备对应的第一波束方向信息、第一加权值和第二加权值确定为所述波束确定信息
综上所述，本公开提供的波束确定方法之中，基站会接收至少一个终端设备上报的第一波束相关信息，该第一波束相关信息为终端设备与中继设备之间波束对应的相关信息。之后，基站会基于第一波束相关信息获取波束确定信息，该波束确定信息用于确定目标波束，该目标波束为：中继设备向至少一个终端设备进行中继转发时所使用的波束。由此可知，本公开提供了一种波束确定方法，用于确定中继设备向至少一个终端设备转发基站发送的信号时所使用的目标波束，本公开的方法较为简洁，可以快速有效地确定多用户场景中的中继转发方向。并且，本公开在确定目标波束时，还会考虑到终端设备与中继设备之间波束的波束质量，以使得所确定出的目标波束的波束方向会无限接近于波束质量高的波束的方向，从而保证了所确定出目标波束的波束质量，由此，当中继设备基于目标波束向至少一个终端设备转发基站发送的信号时，可以确保转发精度，使得至少一个终端设备均可以精确接收到中继设备转发的信号，提高了信号传输精度。
图3为本公开实施例所提供的一种波束确定方法的流程示意图，该方法由基站执行，如图3所示，该波束确定方法可以包括以下步骤：
步骤301、基于波束确定信息确定目标波束，并向中继设备发送第二波束相关信息，该第二波束相关信息包括目标波束的相关信息。
其中，在本公开的一个实施例之中，基站确定出波束确定信息之后，可以先基于波束信息确定出目标波束，再向中继设备发送第二波束相关信息，以便中继设备可以直接基于第二波束相关信息来利用目标波束向至少一个终端设备转发基站发送的信号，而不需要中继设备自行确定目标波束，其中，基站发送的信号可以理解为：基站要向一个或多个终端设备发送的通信交互信号，该通信交互信号可以是由中继设备转发至一个或多个终端设备。
以及，在本公开的一个实施例之中，上述的基于波束确定信息确定目标波束的方法可以包括以下步骤：
步骤1、将至少一个终端设备与中继设备之间波束的第一维度角度值与至少一个终端设备的第一加权值的乘积求和得到目标波束的第一维度角度值。
示例的，假设当前通信场景中包括三个终端设备，分别为终端设备#1、终端设备#2、终端设备#3，其中，基站基于该三个终端设备上报的第一波束相关信息确定出终端设备#1、终端设备#2、终端设备#3与中继设备之间波束的第一维度角度值分别为：α 1，α 2，α 3；其中，针对终端设备#1、终端设备#2、终端设备#3设置的第一加权值分别为：c 1,c2 ,c 3∈[0,1]，c 1+c 2+c 3＝1；则计算出的目标波束的第一维度角度值可以为：c 1*α 1+c 2*α 2+c 3*α 3。
步骤2、将至少一个终端设备与中继设备之间波束的第二维度角度值与至少一个终端设备的第二加权值的乘积求和得到目标波束的第二维度角度值。
示例的，假设当前通信场景中包括三个终端设备，分别为终端设备#1、终端设备#2、终端设备#3，其中，基站基于该三个终端设备上报的第一波束相关信息确定出终端设备#1、终端设备#2、终端设备#3与中继设备之间波束的第二维度角度值分别为：β 1,β 2,β 3；其中，针对终端设备#1、终端设备#2、终端设备#3设置的第二加权值分别为：d 1,d 2,d 3∈[0,1]，d 1+d 2+d 3＝1；则计算出的目标波束的第二维度角度值可以为：d 1*β 1+d 2*β 2+d 3*β 3。
步骤3、基于目标波束的第一维度角度值和目标波束的第二维度角度值确定出目标波束。
则由上述步骤1-步骤3可知，基站具体是通过对各个终端设备与中继设备之间波束的波束方向分别加权后求和来确定出中继设备向至少一个终端设备转发信号时所使用的目标波束的波束方向的，而参 考上述步骤202的相关介绍可知，各个终端设备的加权值(即第一加权值和第二加权值)具体是和终端设备与中继设备之间波束的质量相关的，如各个终端设备的加权值可以是和终端设备与中继设备之间波束的质量相关呈正相关，或者，与中继设备之间波束的质量最高的终端设备的加权值为1，其他终端设备的加权值为0，由此可知，本公开中终端设备与中继设备之间波束的质量越高，该终端设备的加权值越大。基于此，当通过上述加权求和的方法确定目标波束的波束方向时，可以使得所确定出的目标波束的波束方向会无限接近于波束质量高的波束的方向，从而保证了所确定出目标波束的波束质量，由此，当中继设备基于目标波束向至少一个终端设备转发基站发送的信号时，可以确保转发精度，使得至少一个终端设备均可以精确接收到中继设备转发的信号，提高了信号传输精度。
进一步地，在本公开的一个实施例之中，上述的第二波束方向信息可以包括以下至少一种：
第二波束方向信息，所述第二波束方向信息包括目标波束的第一维度角度值和目标波束的第二维度角度值；
目标波束对应的波束索引，其中，该波束索引可以是基站与中继设备预先定义好的；
目标波束对应的参考信号的信息；
目标波束对应的所述中继设备的天线端口或天线单元的相位调整信息；其中，所述相位调整信息用于：基于所述相位调整信息调整所述中继设备的天线端口或天线单元能使得所述中继设备实现基于所述目标波束发射信号；
第二PMI，所述第二PMI为所述目标波束对应的PMI。
综上所述，本公开提供的波束确定方法之中，基站会获取到波束确定信息后，会基于该波束确定信息确定目标波束，并向中继设备发送第二波束相关信息，该第二波束相关信息包括目标波束的相关信息。由此可知，本公开提供了一种波束确定方法，用于确定中继设备向至少一个终端设备转发基站发送的信号时所使用的目标波束，本公开的方法较为简洁，可以快速有效地确定多用户场景中的中继转发方向。并且，本公开在确定目标波束时，还会考虑到终端设备与中继设备之间波束的波束质量，以使得所确定出的目标波束的波束方向会无限接近于波束质量高的波束的方向，从而保证了所确定出目标波束的波束质量，由此，当中继设备基于目标波束向至少一个终端设备转发基站发送的信号时，可以确保转发精度，使得至少一个终端设备均可以精确接收到中继设备转发的信号，提高了信号传输精度。
