    Abstract: A system and a method is disclosed for selecting at least one vertical precoding vector of a three-dimensional Multiple Input Multiple Output (3D-MIMO) configuration based on Channel State Information-Reference Signal (CSI-RS) information that is feedback from a wireless terminal device to an evolved Node B (eNB). The 3D-MIMO CSI-RS process is configured for a plurality of CSI-RS ports in which the plurality of CSI-RS ports that are grouped into a plurality of CSI-RS port groups and in which corresponds to the 3D arrangement of antennas. CSI configuration information for the different CSI-RS port groups can be a time-domain-based CSI-RS process, a frequency-domain-based CSI-RS process, a code-domain-based CSI-RS process, or a combination thereof. CSI-RS information is measured for each CSI-RS group and feedback for selection of the at least one vertical precoding vector.
