A method for orbital angular momentum (OAM) beam communication includes: transmitting a reference signal (RS) to a receiver; receiving feedback information provided by the receiver based on the RS; determining a weight vector corresponding to the transmitter based on the information, in which, the weight vector adjusts a divergence angle of an OAM beam transmitted by the transmitter; determining an OAM signal to be transmitted, and adjusting a divergence angle of the OAM signal to be transmitted based on the weight vector to obtain an adjusted OAM beam; transmitting the adjusted OAM beam.

Method and apparatus for OAM beam communication

A method for determining a transmission array of an orbital angular momentum (OAM) system, performed by a transmitter, that can include determining a plurality of transmission arrays from a first concentric circular array of the transmitter, transmitting, respectively and sequentially by the plurality of transmission arrays, a first reference signal to a receiver, and receiving first target index information from the receiver, and determining the transmission array of the OAM system based on the first target index information.
