Beam management procedure in a communications network

Abstract:

There is provided mechanisms for a beam management procedure in a communications network. A method is performed by a first radio transceiver device. The method comprises transmitting, in at least one directional transmit beam, a reference signal to a second radio transceiver device as part of the beam management procedure. More than one occurrence of the reference signal is transmitted within one single OFDM symbol. One occurrence for each of two polarizations of the reference signal is transmitted in each of the at least one directional transmit beam within the one single OFDM symbol.
