Abstract

The present invention provides a mobile terminal apparatus, a base station apparatus, and a communication control method, which allow control suitable for interference reduction in a layered network such as HetNet, and which support a next-generation mobile communication system. A mobile terminal apparatus has a receiving section (103) that receives radio frames of a lower cell, in which a protected subframe, the transmission of which by a higher cell is suppressed, and a non-protected subframe, the transmission of which by the higher cell is not suppressed, coexist, a measurement section (112) that measures reception quality from reference signals multiplexed individually on the protected subframe and the non-protected subframe, a feedback information reduction section (114) that calculates a difference value between the reception quality of the protected subframe and the reception quality of the non-protected subframe, and a transmission section (103) that reports reception quality information of the protected subframe, and the difference value calculated in the feedback information reduction section (114), to a base station apparatus (20B).
