A method for geolocating an item of user equipment located at a given altitude, receiving a plurality of radio beams emitted in at least a first and a second propagation direction by at least one antenna of a first base station and by at least one antenna of a second base station, respectively, in at least a third and a fourth propagation direction is disclosed. The method involves: obtaining a power measured by the item of terminal equipment for radio beams emitted by the first base station; calculating at least one item of information per base station, representative of a ratio or of a difference between a first and a second power of each set of measured powers; and determining a position of the item of user equipment at the given altitude.

Method for geolocating an item of user equipment, device, item of user equipment, base station, system and computer program corresponding thereto

A method and device are disclosed for controlling a data-transmission mode used by a vehicle to communicate. In one aspect, the control method includes selectively activating, when a predefined condition C1 or C2 is met, a full-duplex data-transmission mode at a first vehicle to communicate with a second vehicle and with a base station of a network to which the first vehicle is connected.
