Abstract
A wireless communication system includes an upper transmission station and a lower transmission station, each serving as a transmission station, a terminal serving as a reception station. The upper transmission station allocates a downlink control channel for each terminal to part of a predetermined data-channel region ascribed to the lower transmission station based on a demodulation reference signal for each transmission station. Based on the allocation result, the lower transmission station allocates the downlink control channel for each terminal, which is disposed at art of the data-channel region thereof. The terminal decodes the downlink control channel based on the demodulation reference signal.
