The present document captures the findings of the study item "Study on 3D-channel model for Elevation Beamforming and FD-MIMO studies for LTE" [3] and aims to help TSG RAN WG1 to properly model and evaluate the performance of physical layer techniques using 3D channel models. This document relates to the 3GPP evaluation methodology and covers the modelling of the physical layer of both Mobile Equipment (ME) and Access Network (AN) of 3GPP systems. It intends to capture the scenarios relevant to 3D channel models and the modifications to the 3GPP evaluation methodology needed to support 3D channel modelling.
