The objective of the invention is to suitably operate a virtual carrier to be used in an MTC by avoiding interferences from control signals and synchronization signals inserted in the data areas of subframes transmitted from a macro eNodeB.
The objective of the invention is to suitably operate, under a heterogeneous environment, a virtual carrier to be used in an MTC. A pico eNodeB places a virtual carrier in such a manner that avoids the positions of the central 72 subcarriers of a donor band, or the pico eNodeB stops the operation of the virtual carrier in a particular subframe or stops a control area (PDCCH_MTC) of the virtual carrier in such a manner that avoids a particular subframe, thereby avoiding interferences from control signals (BCH) and/or synchronization signals (PSS, SSS) inserted in the data areas (PDSCH) of subframes transmitted from a macro eNodeB.
