Design of downlink control channels for MHN enhanced system

In spite of the high need for high data rate for users, there has been no wireless mobile backhaul system supporting 10Gbps data rate for fast moving group vehicle such as a subway and a train. In ETRI, we have been designing and developing MHN-E (Mobile Hotspot Network - Enhanced) system to meet the criteria which is focused on fast moving vehicle. MHN-E system supports up to 10Gbps downlink data transmission rate for fast moving group vehicle. Supported moving velocity is considered up to 500km/h. In this paper, downlink control channel structures of MHN-E system are described and their performances are shown.
