FIELD: wireless communication.
SUBSTANCE: method, for use in a network node, transmitting reference information of channel state information (CSI-RS) comprises steps, at which: transmitting (1714) to wireless device indication of subset of physical resource blocks (PRB), which wireless device must use to measure CSI-RS, wherein each CSI-RS is associated with an antenna port, wherein the PRB subset comprises a subset of all PRBs in the system bandwidth, wherein indicating a subset of the PRB, which wireless device is to use to measure CSI-RS, comprises a density value and a comb offset; and transmitting (1716) CSI-RS over said subset of PRB.
EFFECT: technical result consists in reducing CSI-RS losses and facilitating more CSI-RS configurations with 32 ports.
