1. A method for beam management comprising:
obtaining, by a Light Detection and Radar (LIDAR) sensor having one or more LiDAR cameras performing ray-tracing, out-of-band infrared measurements of a surrounding environment; and
selecting, by a base station, a transmission and reception beam pair for use in the surrounding environment from a plurality of available transmission and reception beam pairs responsive to the out-of-band measurements of the surrounding environment by:
pre-computing beam assignments over a three-dimensional (3D) grid of possible transmission and reception positions within a 3D model of reflected power modelled as a combination of specular reflection and diffuse scattering within the surrounding environment; and
fulfilling a beam assignment request via a table lookup of a lookup table specifying paths for the transmission and reception beam pairs.
