Abstract
Systems and methods may facilitate initial establishment and/or handover of an air-to-ground (ATG) communication link between an aircraft and a ground-based cellular communication network (e.g., a 5G network). The systems and methods may be particularly applicable for an aircraft having a user equipment (UE) antenna that uses narrow beamforming to connect to a cell of a base station (gNB). The UE identifies candidate cells based upon the location of the UE and locations and orientations of cells in the network, identifies a cell having a higher likelihood of connection success compare to other cells, and directs a beam to the chosen cell. The systems and methods may enable the UE to create neighbor lists in real time based upon the UE location, and may prevent blind searching normally associated with narrow beamforming methods.
