1. A method for performing a beam management procedure, the method being performed by a network node, the method comprising:
obtaining configuration information from a terminal device for which the network node provides network access, wherein the configuration information specifies that the terminal device is in need for evaluating different polarization states in different time units during the beam management procedure; and
performing the beam management procedure with the terminal device, wherein the beam management procedure involves the network node to, per slot, transmit reference signals according to a reference signal transmission scheme, and wherein the reference signal transmission scheme depends on the obtained configuration information.
