1. A method for wireless communication, the method comprising:
receiving, by a receiving node, an orbital angular momentum (OAM) signal from a transmitting node;
determining, by the receiving node, one or more non-coaxial parameters according to the OAM signal by traversing a set of grid points corresponding to a non-coaxial parameter of the one or more non-coaxial parameters and selecting a value from the set of grid points for the non-coaxial parameter; and
selecting, by the receiving node, at least one beam from a plurality of beams for communication with the transmitting node according to the one or more non-coaxial parameters.
