Claim 15:
16. A non-transitory machine readable medium comprising instructions that, when executed, cause a User Equipment (UE) to:
receive a configuration message that comprises 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 configuration message comprises indications of 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;
receive the configurable density CSI-RS from the set of REs; and, measure the configurable density CSI-RS to determine one or more CSI parameters;
wherein the one or more configuration parameters are provided per CSI-RS resource configuration.
