Zusammenfassung:	There is provided mechanisms for determining direction of a second radio transceiver device with respect to a first radio transceiver device. The first radio transceiver device is configured to communicate with beams in a beam set. A method is performed by a processing unit. The method comprises obtaining a vector of radio parameter measurements from measurements performed on a radio link between the first radio transceiver device and the second radio transceiver device for one and the same location of the second radio transceiver device. The vector comprises a radio parameter measurement per each beam in the beam set. The method comprises determining the direction of the second radio transceiver device with respect to the first radio transceiver device by comparing the vector of radio parameter measurements to a set of candidate direction profiles.
