摘要： A process for cooperative aerial inter-antenna beamforming for communication between (a) multiple moving platforms, each platform having an aerial antenna mounted thereon, such that the aerial antennas have variable positions and orientations over time, and (b) at least one antenna mounted on user equipment having a lower altitude than the aerial antennas; the process involving transmitting data relating to the positions and orientations of the aerial antennas to a processing system, the processing system calculating and transmitting beamforming instructions to the aerial antennas, the aerial antennas thereby transmitting or receiving respective component signals for each user antenna, the component signals for each user antenna having essentially the same information content but differing in their phase and usually amplitude, so as to form a cooperative beam from the cooperative sum of the signals between the aerial antennas and the user antenna. A method of determining the position of a moving aerial antenna or antenna element mounted on at least one moving platform, such that the aerial antennas have variable positions and orientations over time, the method involving determining the phase difference yi, being a fraction of a wavelength between the values 0 and 1, between signals of known wavelength λi; transmitted between (a) i ground based transmitters which may be backhaul base stations, wherein i is at least three, the ground based transmitters having known position to within λi/10 and (b) the aerial antenna or antenna element, thereby establishing the distance from the base station to the aerial antenna or antenna element to be λi(ni+yi), wherein ni is an unknown integer; determining the position of the aerial antennas or antenna elements approximately by differential GPS or other methods to within a small number of wavelengths λi thereby establishing that ni can be one of a limited number of possible integer values for each signal; the number of base stations and their positions being sufficient to allow elimination of the possible values of ni that are inconsistent with the limited number of possible values for ni from the other ground based transmitters, until only one integer value for each ni is established; establishing the location of the aerial antenna or antenna element by triangulation of its known distance λi(ni+yi), from at least three ground based transmitters.

摘要： A method for maintaining a connection of mobile user equipment to a core network, and a communication network are disclosed. The method comprises the steps of providing a multi-channel communication link between a user equipment at a first location and a plurality of aerial vehicles, determining that the user equipment is moving whereby a loss of connectivity via the multi-channel communication link may occur, and subsequently, via a handover step, transferring communication between the user equipment and a core network from communication via the multi-channel communication link to communication via a single channel communication link provided by a respective aerial vehicle.
