There is provided mechanisms for a radio transceiver device to participate in beam management. A method is performed by the radio transceiver device. The method comprises receiving a reference signal from another radio transceiver device as part of participating in the beam management. The reference signal occupies time/frequency resources that extend over a frequency interval. The reference signal is simultaneously received in a set of beams where each beam has a unique frequency dependent phase shift such that all beams in the set of beams point in mutually different directions and each beam covers its own part of the frequency interval.
