Abstract
The present invention is designed to reduce interference from a macro base station to a small transmission power node. The present invention is characterized in providing a micro base station which forms, in a macro cell where a macro base station transmits a signal to a macro terminal, a micro cell where the micro base station transmits a signal to a micro terminal under control with low power, and this micro base station generates a PDCCH which includes downlink or uplink resource allocation information, and, in a non-transmission period in which the macro base station stops transmitting signals while leaving minimal quality measurement signals, shifts the transmission starting symbol of the PDCCH to a position where the PDCCH does not overlap the quality measurement signals.
