Claim 0:
1. An apparatus configured to be employed for a UE (User Equipment), comprising:
a memory interface; and
processing circuitry coupled to the memory interface and configured to cause the 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, the one or more configuration parameters indicating 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 based on the one or more configuration parameters; and
determine one or more CSI parameters based on measurements of the configurable density CSI-RS from the set of REs;
wherein the one or more configuration parameters are provided per CSI- RS resource configuration.
