IMS 2014: Super High Bit Rate Radio Access Technologies for Small Cells Using Higher Frequency Bands

This paper overviews super high bit rate radio access technologies using higher frequency bands for future radio access for 5G. In small cells using higher frequency bands based on the Phantom Cell concept in which radio links for the control (C)-plane and user (U)-plane are separately connected to a macro cell and small cell, radio access technologies employing Massive Multiple-Input Multiple-Output (MIMO) are described that achieve super high bit rate transmission.
