Abstract:
1. A mobile terminal apparatus comprising: a receiver that receives radio frames of a lower cell including a protected subframe being a subframe transmission from a higher cell that is inhibited and a non-protected subframe being a subframe transmission from the higher cell that is not inhibited; a measurement circuit that measures reception quality from reference signals multiplexed individually on the protected subframe and the non-protected subframe; a feedback information reduction that calculates a difference value between the reception quality of the protected subframe and the reception quality of the non-protected subframe; and a transmitter that notifies reception quality information of the protected subframe measured by the measurement circuit, and the difference value calculated by the feedback information reduction circuit to a base station apparatus for allocating radio resources to the mobile station, wherein, when the difference value calculated by the feedback information reduction circuit is lower than a threshold value, the transmitter notifies only the reception quality information of the protected subframe to the base station apparatus.
