Claim 13:
14. The apparatus of claim 7, wherein the processing circuitry is further configured to renumber the one or more CSI-RS APs such that the processing circuitry is configured to map the configurable density CSI-RS for one CSI-RS AP to a first RE of an associated RE pair of an associated CDM (Code Division Multiplexing) group and to map, to a second RE of the associated RE pair of the associated CDM group, the configurable density CSI-RS for an additional CSI-RS AP, wherein that CSI-RS AP and the additional CSI-RS AP are associated with a common beam, wherein that CSI-RS is associated with a first polarization of the common beam and the additional CSI-RS AP is associated with a distinct second polarization of the common beam.
