Abstract

本申请实施例涉及确定配置参数的方法、终端设备和网络设备。该方法包括：接收网络设备发送的多层码本中每层码本的配置参数，该多层码本的配置参数中存在至少一种配置参数在不同层码本中设置为不相同，其中，该每层码本的配置参数包括以下参数中的至少一种：该每层码本的空间域离散傅里叶变换DFT向量的个数、该每层码本的频域DFT向量的个数、该每层码本的加权系数矩阵中最大非零元素的个数、该每层码本的加权系数矩阵的量化精度以及该每层码本的不同量化精度的个数，该量化精度包括幅度的量化精度和/或相位的量化精度。本申请实施例的确定配置参数的方法、终端设备和网络设备，能够降低多层码本的开销，进而提高系统效率。
