下面结合附图对本申请所提供的上行MIMO传输的8天线端口多天线面板的码本确定方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种上行MIMO传输的8天线端口多天线面板的码本确定方法的流程示意图。如图2所示，该方法可以包括但不限于如下步骤：
S201，确定第一传输层的第一波束。
随着传输需求和传输场景的增强，上行传输可以支持增多的天线端口和上行传输层数即天线端口数量可以从4天线端口增多到最大8天线端口。
本申请实施例中，为了上行MIMO传输支持8天线端口的传输，在设计上行MIMO传输8天线端口多天线面板的码本，可以参考现有协议R15中下行类型I(DLType I)多天线面板的码本设计。由于现有协议R15中下行类型I(DLType I)多天线面板的码本设计仅支持传输层数为1层到4层。本申请实施例中提供的上行MIMO传输8天线端口多天线面板的码本，仅支持传输层数为1层到4层，也就是说，传输层数L为正整数，大于或者等于1且小于或者等于4。
本申请实施例中，可以预先确定第一传输层的第一波束v l,m。其中，波束的计算公式为：
Figure PCTCN2022120606-appb-000001
Figure PCTCN2022120606-appb-000002
其中，N 1、N 2分别是第一维度天线端口数和第二维度天线端口数，O 1、O 2分别是第一维度过采样值和第二维度过采样值。
S202，确定用于构建8天线端口码本时采用的码本系数，其中，码本系数包括第一共相位系数和天线面板间的补偿因子。
可选地，在多天线面板的情况下，码字系数包括共相位系数和天线面板的补偿因子。需要说明的是，在不同的天线结构下，对应的共相位系数不同。
每个天线面板包括第一极化方向和第二极化方向，可选地，确定第一极化方向上的共相位系数为1，确定第二极化方向上的共相位系数为
Figure PCTCN2022120606-appb-000003
可选地，第n g天线面板的面板间补偿因子为
Figure PCTCN2022120606-appb-000004
也就是说，第一个天线面板的面板间补偿因子可以为
Figure PCTCN2022120606-appb-000005
第二天线面板的面板间补偿因子为
Figure PCTCN2022120606-appb-000006
依次类推。
可选地，共相位系数可以采用如下公式确定：
Figure PCTCN2022120606-appb-000007
可选地，可以网络通过共相位系数的索引进行指示。
可选地，天线面板间补偿因子可以采用如下公式确定：
Figure PCTCN2022120606-appb-000008
可选地，可以网络通过天线面板间补偿因子的索引进行指示。
S203，根据第一波束和码本系数，确定8天线端口多天线面板L层的码字。
需要说明的是，L用于表示终端设备所支持的最大上行MIMO传输的传输层数，L的取值为正整数，L大于或者等于1且小于或者等于4。
可选地，根据所述第一波束和所述共相位系数，确定首个天线面板的8天线端口多天线面板L层 的第一码字。可选地，确定与所述第一波束正交的第二波束，根据第一共相位系数，确定可使码字正交的第二共相位系数。进一步地，根据第一波束和第二波束，以及第一共相位系数和第二共相位系数中的至少部分参数，确定首个天线面板的第一码字，也就是说，可以基于第一波束和第二波束，以及第一共相位系数和第二共相位系数中的部分参数或全部参数，确定首个天线面板的第一码字。可以理解的是，第一波束和第二波束为二维(2D)的离散傅里叶变换(Discrete Fourier Transform，DFT)波束。
在一些实现中，可以第一波束和第二波束，以及第一共相位系数和第二共相位系数，确定首个天线面板的第一码字，例如，将第一波束分别与第一共相位系数和第二共相位系数组合，以及将第二波束分别与第一共相位系数和第二共相位系数组合，得到首个天线面板的第一码字。
在又一些实现中，可以将第一波束与第一共相位系数组合，以及将第二波束与第一共相位系数组合，得到首个天线面板的第一码字。
在另一些实现中，可以将第一波束分别与第一共相位系数和第二共相位系数组合，得到首个天线面板的第一码字。
进一步地，根据首个天线面板的8天线端口多天线面板L层的第一码字和第n g个天线面板的面板间补偿因子，确定所述第n g个天线面板的所述8天线端口多天线面板L层的第二码字。其中，2≤n g≤N g，N g为天线面板的数量。
本申请实施例中可以基于第一传输层的第一波束和码本系数，构建高维度8天线端口多天线面板的传输码字，能够满足上行MIMO支持8天线端口多天线面板的1层至4层传输的需求，进而对上行MIMO技术进一步增强。
实现中可以将8天线端口分为1或2或4个端口组，其中，端口组可定义为面板或其他可能的定义，天线端口组内的天线端口相干传输，天线端口组间的天线端口可以相干或非相干传输。因此，可考虑下列多天线面板情况：
情况a1：天线端口组数为2，天线面板数为2，2个面板间相干传输。
情况a2：天线端口组数为2，天线面板数为2，2个面板间非相干传输。
情况b1：天线端口组数为4，天线面板数为4，4个面板间相干传输。
情况b2：天线端口组数为4，天线面板数为4，1个面板相干传输，另外3个面板间相干传输。
情况b3：天线端口组数为4，天线面板数为4，2个面板间相干传输，另外2个面板间相干传输。
情况b4：天线端口组数为4，天线面板数为4，4个面板间非相干传输。
可以对上述不同的情况进行归纳，得到下列三种多天线面板的相干传输方式：
传输方式1：天线面板间全相干传输，对应情况a1和情况b1。
传输方式2：天线面板间部分相干传输，对应情况b2，情况b3。
传输方式3：天线面板间非相干传输，对应情况a2，情况b4。
