摘要： The present invention is designed to provide highly efficient small cell radio access. Local stations (20) transmit small cell-specific DISCOVERY SIGNALS, and a mobile terminal apparatus (10) receives MEASUREMENT CONFIGURATION, in which a DS reception control signal is contained, from a macro station (30). The mobile terminal apparatus (10) receives the DISCOVERY SIGNALS based on control information reported by the MEASUREMENT CONFIGURATION. The macro station (30) selects local stations whose CSI information is to be fed back, based on DISCOVERY SIGNAL MEASUREMENT reports, and reports RRC CONNECTION RECONFIGURATION, in which local station information for feeding back CSI information is contained, to the mobile terminal apparatus (10).
