Original Abstract Submitted

there is provided mechanisms for transmitting reference signals via a meta-surface. a method is performed by a network node. the network node serving user equipment via at least one meta-surface over a radio propagation channel. the method comprises defining a set of reference signal indices based on number of beams in which a reference signal is to be transmitted and number of meta-surface configurations applicable to the at least one meta-surface. each of the meta-surface configurations represents a respective set of phase shifts as applied at the at least one meta-surface. the method comprises defining a mapping between the reference signal indices and the beams. the mapping defines which of the reference signal indices to be transmitted in which of the beams. the method comprises transmitting, in the beams and according to the mapping, the reference signal with the reference signal indices over the radio propagation channel.
