There is provided mechanisms for beam management. A method is performed by a network node. The method comprises performing abeam management procedure for terminal devices served by the network node. The method comprises transmitting, during a first part of the beam management procedure, a reference signal so as to enable each of the terminal devices participating in the beam management procedure to identify in which beam in a first set of beams, in which the reference signal is transmitted from the network node, the reference signal is received with highest received power. The method comprises transmitting, during a second part of the beam management procedure, the reference signal so as to enable each of the terminal devices to identify in which beam in a second set of beams, in which the reference signal is received from the network node by the terminal devices, the reference signal is received with highest received power. The method comprises transmitting, during a third part of the beam management procedure, the reference signal so as to enable each of the terminal devices participating in the beam management procedure to identify for which beam in a third set of beams, in which the reference signal is transmitted from the network node, the reference signal is received with highest received power. There is one respective third set of beams for each respective beam in the first set of beams. The third part of the beam management procedure is performed for each respective third set of beams. The second part is performed before the third part at least for one of the respective third set of beams.
