Abstract: The invention relates to a device (10) for a cellular communications network (1000), wherein said device (10) includes at least a processor (12), a memory (14) and a transceiver (16) and is configurable to: determine (300) a parameter (P) which characterizes a relative velocity (v_rel) of said device (10) with respect to a base station (110) of said cellular communications network (1000), and to modify (302) a timing of at least one uplink transmission (ul) from said device (10) to said base station (110) depending on said parameter (P).

Abstract: Systems, methods, apparatuses, and computer program products for handover (HO) in long term evolution (LTE) air-to-ground (A2G) networks are provided. One method may include determining, by a terminal associated with an air-to-ground network, a distance from the terminal to at least one cell of the air-to-ground network. When the distance is less than a maximum distance limit, the method may comprise including at least one of an identity of the at least one cell, a signal strength of the at least one cell, or the distance, in a measurement report that is transmitted to the network.
