1. A network node for beam management, the network node comprising processing circuitry, the processing circuitry being configured to cause the network node to:
perform a beam management procedure for terminal devices served by the network node, wherein performing the beam management procedure comprises:
transmitting, during a first part of the beam management procedure, a first reference signal so as to enable more than one of the terminal devices participating in the beam management procedure to identify in which beam, in a first set of beams in which the first reference signal is transmitted from the network node, the first reference signal is received with highest received power, for reporting in a respective first report;
transmitting, during a second part of the beam management procedure, distinct from the first part, a second reference signal so as to enable the more than one of the terminal devices to identify in which beam, in a second set of beams in which the second reference signal is received from the network node by the terminal devices, the second reference signal is received with highest received power; and
transmitting, during a third part of the beam management procedure, a third reference signal so as to enable the more than one of the terminal devices participating in the beam management procedure to identify for which beam, in a third set of beams in which the third reference signal is received, by each respective more than one of the terminal devices, with highest received power,
wherein there is one respective third set of beams for each respective beam in the first set of beams identified in the respective first reports, wherein the third part of the beam management procedure is performed for at least one beam in each respective third set of beams, and wherein the second part is performed before the third part for each respective more than one of the terminal devices.
