Claim Text:
1. A radio base station forming a macro-cell to transmit a downlink signal including a data signal using a first carrier where a micro-base station that transmits a data signal using a second carrier associated with the first carrier is disposed in the macro-cell, comprising: a determination section that determines whether or not the micro-base station transmits a non-data signal that is at least one of a synchronization signal, a broadcast signal, a measurement reference signal and a downlink control signal using the second carrier; and a transmission section that transmits instruction information for instructing the micro-base station to start transmission of the non-data signal using the second carrier to the micro-base station when the determination section determines that the micro-base station transmits the non-data signal, wherein the determination section determines whether or not the micro-base station transmits the non-data signal non-periodically, and when the determination section determines that the micro-base station transmits the non-data signal non-periodically, the instruction information includes bit information for instructing a transmission start of the non-data signal.
