Abstract: Techniques discussed herein can facilitate reduced density CSI (Channel State Information)-RS (Reference Signals). One example embodiment can be employed at a UE (User Equipment) and can comprise processing circuitry configured to: process one or more configuration messages that comprise one or more configuration parameters for one or more CSI (Channel State Information)-RS (Reference Signal) APs (Antenna Ports) of a reduced density CSI-RS, wherein the one or more configuration parameters indicate a PRB (Physical Resource Block) decimation and a PRB offset; determine a set of REs (Resource Elements) for the one or more CSI-RS APs of the reduced density CSI-RS based on the one or more configuration parameters; measure the reduced density CSI-RS from the set of REs to determine one or more CSI parameters.
