“…In this case, BM can be translated to the traditional satellite acquisition and tracking operations, which were developed for years targeting satellite-on-the-move terminals or more recently LEO connectivity. Such systems rely on the combination of open-loop techniques to roughly estimate the position of the targeted satellite and closed-loop solutions to refine the beam pointing [5]. Open-loop techniques use geolocation, satellite ephemeris and inertial sensors, whereas for closed-loop, the transmission of a reference signal is used to perform any kind of sequential scanning [6].…”

This work reviews the beam management framework of New Radio, identifies the challenges to be addressed for a proper operation in non-terrestrial network and numerically evaluates its suitability for satellite beam selection, satellite tracking and satellite acquisition in the case of LEO constellations. It reveals that satellite beam selection and satellite tracking can be performed efficiently, while acquisition times are in the range of a few to tenths of seconds, in the case that no GNSS and ephemeris information is exploited, as considered in future 3GPP releases towards 6G. These delays may be acceptable for a pure initial acquisition, but new solutions are needed for efficient satellite handovers or idle mode operation.
