Performance of downlink control channels for Mobile Hotspot Network system

Currently, the high speed data rate services for mobile group vehicles moving at high speed are acutely required. In ETRI (Electronics and Telecommunications Research Institute), we have been developing the Mobile Hotspot Network (MHN) system that can support over 1.2Gbps data rate services for mobile group vehicles moving at high speed over 400km/h, e.g., KTX, TGV, etc. In this paper, new frame structures and pilot patterns for FDD (Frequency Division Duplex) and TDD (Time Division Duplex) of MHN system are proposed. Furthermore, the physical downlink control channels are defined, and we show the structure of designed downlink control channels. We verified the performance of the downlink control channels by computer simulation. Currently, we are developing the test-bed of MHN system and having a target to demonstrate the real time performance of the MHN system on the outdoor environment in 2014. In this paper, we are focusing at the performance of MHN DL control channels. We also show the performance of these channels meet the required SNR.
