Provided are a base station apparatus, a mobile terminal apparatus and a communication control method capable of preventing the increase in amount of signaling for uplink scheduling when allocation resource blocks are allocated in a discontiguous manner. The base station apparatus (20) determines discontiguous allocation positions of a first cluster and a second cluster to a frequency band. The frequency band is divided per RBG of a relatively small size (2 RBs) and the RBG is composed of contiguous RBs. The base station apparatus (20) indicates the allocation positions of the first cluster and the second cluster to a mobile terminal apparatus (10) with use of a group number of RBG of a relatively large RBG size (4 RBs). |
