This application provides a channel estimation method, apparatus, storage medium, and program product. The method includes: estimating the angle of a base station and a first scattering object surrounding the base station using a discrete Fourier transform algorithm to determine first angle information; designing a codebook-based transmit beamforming matrix based on the first angle information; and transmitting an uplink pilot signal to the base station based on the codebook-based transmit beamforming matrix. The solution of this application, based on the determined angle information, designs a codebook-based transmit beamforming matrix, improving the accuracy of uplink channel estimation and overcoming the limitations of channel estimation in traditional MIMO-OFDM systems.
