METHOD AND APPARATUS FOR BEAMFORMING, DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2024/026639

A1

Provided in the present disclosure are a method and apparatus for beamforming, a device, and a storage medium. The method comprises: determining a first beamforming vector corresponding to each array unit in a transmitting array of a transmitting end, wherein a first beamforming vector is used for adjusting the transmitting beam direction of the array unit, such that the direction of the beam transmitted by each array unit is adjustable; determining a second beamforming vector corresponding to each array unit, the second beamforming vector being used for forming an orbital angular momentum (OAM) beam; and performing beamforming on a transmitted signal on the basis of the first beamforming vector and the second beamforming vector. According to the method provided by the present disclosure, transmitting beam divergence is prevented and the divergence angle of the transmitting beam is reduced, such that the problem that "due to the divergence characteristic of an OAM beam, receiving end UCA arrays of different sizes must be designed for different transmission distances" is prevented. Meanwhile, manufacturing costs are reduced, and the problem that an OAM system cannot be remotely transmitted due to the divergence angle is also solved.
