Abstract :
A downlink control channel is proposed for mobile backhaul in hierarchical telecommunications network. The mobile backhaul will suffer from degradation of performance caused by fast variation of channel. To cope with this deterioration, we propose to use FDM-type control channel and precoding 4 antennas for beamforming. The first OFDM symbol is common control field which having resource index of the following control channel. Simulation result shows that the proposed control channel has better performance than that of LTE if the precoding matrix is appropriately selected.
