1. A method for determining a transmission array of an orbital angular momentum (OAM) system, performed by a transmitter, comprising:
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;
transmitting, sequentially by the transmission array of the OAM system, a plurality of second reference signals; wherein the plurality of second reference signals are respectively and sequentially received by a plurality of receiving arrays of the receiver and are configured to cause the receiver to determine a second target signal from the plurality of second reference signals and determine a receiving array corresponding to the second target signal as a receiving array of the OAM system.
