Abstract: Spatial and antenna information of a UAV is determined. Using at least the spatial and antenna information, a set of candidate transmission-reception beam pairs is determined, each pair between one of a set of one or more antenna panels in the UAV and one of multiple TRPs, wherein one or more of the multiple TRPs includes a receiver-only antenna panel that is oriented upward. Beam sweeping is configured to be performed for the set of candidate transmission-reception beam pairs. Based on results of the beam sweeping, a transmission-reception beam pair of the set of candidate transmission-reception beam pairs is selected to be used for uplink communication(s) from the UAV to a determined TRP in the determined best transmission-reception beam pair. The UAV may send the spatial and antenna information toward a wireless communication network including the multiple TRPs, and may send this periodically or based on thresholds.
