Abstract:
Apparatus, methods, and computer-readable media are disclosed herein for facilitating spatial misalignment tracking for OAM beams in millimeter wave and higher frequency bands. An example method for wireless communication at a first communication device includes receiving, from a second communication device, a first misalignment tracking RS and a second misalignment tracking RS for an OAM transmission. The example method also includes determining a misalignment based on the first misalignment tracking RS, the second misalignment tracking RS, and using a subset of antenna elements of an antenna array of the first communication device. Additionally, the example method includes adjusting reception of a subsequent OAM transmission from the second communication device at the antenna array of the first communication device.
