1. A method for cell selection by an airborne UE, the method comprising:
receiving a first downlink signal comprising a first set of airborne UE parameters from a first cell, the first set of airborne UE parameters comprising a radiation center height of a first set of one or more antennas of the first cell, wherein the first set of airborne UE parameters are communicated via one or more information elements of a synchronization signal;
receiving a second downlink signal comprising a second set of airborne UE parameters from a second cell, the second set of airborne UE parameters comprising a radiation center height of a second set of one or more antennas of the second cell; and
based on a determination that the first set of airborne UE parameters, including the radiation center height, is preferable to the second set of airborne UE parameters, including the radiation center height, selecting the first cell for a wireless connection,
wherein the determination that the first set of airborne UE parameters is preferable to the second set of airborne UE parameters comprises determining that the radiation center height of the first set of one or more antennas is within a predetermined threshold of the radiation center height of the second set of one or more antennas and that a vertical beamwidth of the downlink signal radiation pattern associated with the first downlink signal is greater than the vertical beamwidth of the downlink signal radiation pattern associated with the second downlink signal.
