1. A method of wireless communication at a first device, comprising:
receiving, at the first device, an orbital angular momentum (OAM) waveform from a second device, wherein the OAM waveform is spatially misaligned with respect to the second device, and wherein a spatial misalignment of the OAM waveform comprises at least one of a non-parallel misalignment or a rotational misalignment;
sending, from the first device for the second device, a report based on the spatial misalignment, wherein the report includes at least one of spatial coordinates to correct the spatial misalignment or one or more channel measurements of the OAM waveform; and
receiving, at the first device, an adjusted OAM waveform from the second device, wherein the adjusted OAM waveform is spatially aligned with respect to the second device based on the report.
