Title:
MULTI-MODE PRECODING MATRIX INFORMATION REPORT FOR ORBITAL ANGULAR MOMENTUM BASED COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/183469
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A receiving device may receive, from a transmitting device, a configuration indicating a set of orbital angular momentum modes for joint reporting, where 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 set of concentric circular arrays. The receiving device may transmit, to the transmitting device, areport indicating precoding information for each of at least a subset of the set of orbital angular momentum modes, where the precoding information includes one or more first parameters common to the set of orbital angular momentum modes and one or more second parameters for respective ones of the at least the subset of the set of orbital angular momentum modes.
