Abstract

See full text

Aspects of the present disclosure relate to utilizing an intelligent reflecting surface (IRS), a tracking algorithm, or both, to receive, calibrate, and maintain orbital angular momentum (OAM) signaling between wireless devices. The present disclosure describes a first wireless device transmitting spatial-multiple input-multiple output (MIMO) beams to the IRS such that reflected waves from the IRS form a spatial mixture of OAM modes. The IRS may reflect such OAM modes to a second wireless device for subsequent reflection (e.g., a second IRS), reception, calibration, and optimization. For example, the second wireless device may perform pattern recognition of the concentric OAM modes (e.g., by estimating ellipse geometry) to determine the modes of the OAM signaling. The second wireless device may also perform decorrelation, where small perturbations to the elliptical OAM geometry allow the second wireless device to perform one or more optimization techniques related to the OAM signaling.
