Abstract: A method for operating an access node includes sending, to a user equipment (UE), a frequency domain density reduction rate indicator and a frequency shift index indicator for one or more channel state indicator reference signal (CSI-RS) resources, wherein the frequency domain density reduction rate indicator indicates a number of physical resource blocks (PRBs) skipped between successive CSI-RS transmissions and the frequency shift index indicator indicates a shift of a CSI-RS starting PRB.
