Claim 17:
18. A non-transitory machine readable medium comprising instructions that, when executed, cause a base station to:
transmit 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 configurable density CSI-RS, wherein the one or more configuration parameters indicate a density of CSI-RS resource per Physical Resource Block (PRB) per CSI-RS AP and a PRB offset;
determine a set of REs (Resource Elements) for the one or more CSI-RS APs of the configurable density CSI-RS based on the one or more configuration parameters; and
transmit the configurable density CSI-RS for the one or more CSI-RS APs via the determined set of REs; and
wherein the one or more configuration parameters are provided per CSI-RS resource configuration.
