description There is disclosed a method of operating a user equipment in a NR radio access network, wherein the method comprises receiving channel state information reference signaling, CSI-RS, in a CSI-RS pattern. The CSI-RS pattern represents a distribution of subcarriers for carrying CSI-RS over a range of numbered subcarriers, and comprises a first subpattern and a second subpattern. The CSI-RS pattern is based on received first configuration information and received second configuration information. Further, the first configuration information indicates the first subpattern of subcarriers starting at a first starting subcarrier with even number, and the second configuration information indicates the second subpattern starting at a second starting subcarrier with an odd number. The disclosure also pertains to related methods and devices.
