at least one processor coupled to the memory and configured to:
transmit, to a receiver, a positive phase order orbital angular momentum (OAM) transmission on at least one beam;
transmit, to the receiver, a negative phase order OAM transmission on the at least one beam;
receive, from the receiver, a report indicating a relative phase difference between the positive phase order OAM transmission and the negative phase order OAM transmission; and
receive, from the receiver, a beam report indicating a strongest beam index m of the plurality of beams, wherein the strongest beam index m is based on channel quality,
