Multi-mode precoding matrix information report for orbital angular momentum based communication system

A method for wireless communication, comprising:

• transmitting a configuration indicating a set of orbital angular momentum modes for joint reporting, wherein at least one of the set of orbital angular momentum modes is associated with transmission via two or more of a plurality of sets of antennas arranged in a plurality of concentric circular arrays;
• receiving a report indicating precoding information for each of at least two or more orbital angular momentum modes of the set of orbital angular momentum modes, wherein a first portion of the precoding information comprises one or more first parameters common to the set of orbital angular momentum modes and a second portion of the precoding information comprises one or more second parameters for respective ones of the at least two or more orbital angular momentum modes of the set of orbital angular momentum modes;
• and
• transmitting a transmission via one or more of the set of orbital angular momentum modes based at least in part on receiving the report indicating the precoding information.
