Beamforming method, network device, terminal, and storage medium

A network device, comprising a first memory, a first processor, and a program stored in the first memory and executable by the first processor which, when executed by the first processor, causes the first processor to perform a beamforming method comprising:

• acquiring Direction of Arrival (DOA) information;
• obtaining a first beamforming weight WDOA in a first polarized antenna direction according to the DOA information;
• acquiring precoding matrix indicator information;
• obtaining a precoding index value according to the precoding matrix indicator information;
• generating a precoding vector according to the precoding index value and the number of layers of transmitted data, and calculating a complex phase angle of the precoding vector to obtain a phase difference φ (ilayer) between the first polarized antenna direction and a second polarized antenna direction according to the precoding index value, wherein ilayer is the number of layers of the transmitted data;
• obtaining a second beamforming weight {tilde over (W)}DOA in the second polarized antenna direction according to the first beamforming weight WDOA and the phase difference φ (ilayer);
• and
• producing a formed beam according to the first beamforming weight and the second beamforming weight.
