There is provided mechanisms for beam management. A method is performed by a radio transceiver device. The method comprises performing a beam management procedure by simultaneously transmitting a first reference signal in a first set of beams and a second reference signal in a second set of beams. The first set of beams is transmitted at a first antenna array of the radio transceiver device and in a first polarization. The second set of beams is transmitted at a second antenna array of the radio transceiver device and in a second polarization.
