<P>PROBLEM TO BE SOLVED: To provide a radio communication method in the case a macro base station and a micro base station are regarded as a plurality of transmission points, and downlink communication is performed from the plurality of transmission points by use of a plurality of carriers. <P>SOLUTION: In a radio communication method according to the invention, a micro base station (20) determines whether or not a macro base station (10) forming a macro cell will transmit a non-data signal which is at least one of a synchronization signal, a notification signal, a reference signal for measuring, and a downlink control signal from the micro base station by use of a capacity carrier (ST102), if it is determined that the non-data signal will be transmitted from the micro base station, the macro base station will transmit instruction information indicating transmission start of the non-data signal to the micro base station (20) by use of the capacity carrier (ST103), and the micro base station (20) will start transmitting the non-data signal by use of the capacity carrier on the basis of the instruction information from the macro base station (10) (ST104). <P>COPYRIGHT: (C)2013,JPO&INPIT |
