Implementation of downlink control channels for millimeter wave mobile hotspot network system

Currently, the need of high speed data rate services at mobile group vehicles moving at high speed has been increased. In ETRI (Electronics and Telecommunications Research Institute), we have been designing and developing a new wireless mobile backhaul system, Mobile Hotspot Network (MHN) system, which can support over 1Gbps data rate services for mobile group vehicles moving at high speed over 400km/h at KTX (Korea Train Express) train. In this paper, resource allocations and procedures of downlink control channels of MHN system are introduced. Performances of the downlink control channels are verified by computer simulation. Furthermore, implementtations of the downlink control channels are described. We have developed the MHN test-bed system and had a target to demonstrate the real time performance of the MHN system in the outdoor environment at the end of 2015. Outdoor demonstration will be done in subway at line 8 subway in Seoul, Korea.
