Technique for rotating multi-sector antennas on aircrafts

Abstract

A technique for rotating one or more multi-sector antennas mounted on unmanned aircrafts of a radio access network, RAN, is described. Each of the multi-sector antennas comprises multiple sectors. The multiple sectors of each of the multi-sector antennas are configured to provide radio access to radio devices in different azimuthal directions that are changeable relative to the aircraft and fixed relative to each other when rotating the respective one of the multi-sector antennas. As to a method aspect of the technique, the at least one or each of the aircrafts of the RAN determines signal strengths of radio signals exchanged between a first radio device and at least two of the multiple sectors of the multi-sector antenna mounted on the respective one of the aircrafts. Based on the determined signal strengths, a first azimuthal direction is computed for providing radio access to the first radio device. A first sector of the multiple sectors of the multi-sector antenna mounted on the respective one of the aircrafts is rotated in the computed first azimuthal direction.
