Abstract
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.
