Radio base station apparatus and mobile terminal apparatus

Abstract

The present invention provides a radio base station apparatus and a mobile terminal apparatus that can realize efficient reception control when a plurality of mobile communication systems coexist. The radio base station apparatus allocates a control signal of the mobile communication system having a relatively wide system band composed of component carriers to at least two component carriers in a decoding unit composed of a plurality of data blocks, the mobile terminal apparatus corresponding to the mobile communication system receives the control signal, the mobile terminal apparatus demodulates the control signal in a decoding unit composed of a plurality of data blocks and determines whether or not the control signal is directed to the mobile terminal apparatus.
