Abstract: Disclosed is a method which includes determining a traffic load situation and determine a category for the traffic load situation. The method also includes determining, based on the traffic load situation, one or more groups of digital to analog converters to be used, wherein the one or more groups have different resolutions for digital to analog conversions. The method may further include activating the determined one or more groups of digital to analog converters for transmitting signals. Additionally, the method may include transmitting the signals using multiple antennas.

Abstract: Methods and apparatuses for controlling radio resources of radio units in air-to-ground mobile communications systems that include at least an aircraft carrying a transceiver station and a ground basestation, apt to communicate with each other. The radio units are provided with beamforming and/or massive MEM antenna systems, and are controlled by the apparatuses using control data. The apparatuses are configured to receive flight data related to the aircraft, estimate a timed trajectory and a required data rate, as a function of the flight data. Then the apparatuses determine a sequence of control data for said antenna systems to form radio beams and/or connectivity spots directed towards said transceiver station, respectively to the ground basestation, while the allocated data rate is at least equal to the required data rate. The sequence of control data is then provided to respective antenna systems.
