Abstract:
1. A mobile terminal apparatus comprising: a receiver that receives configured to receive a protected subframe in a victim cell corresponding to a subframe with reduced transmission power in an aggressor cell, and a non-protected subframe in the victim cell corresponding to a subframe with unreduced transmission power in the aggressor cell, CRS (Cell-specific Reference Signal) being multiplexed on each of the subframes including the protected subframe and the non-protected subframe, CSI-RS (Channel State Information-Reference Signal) being multiplexed on the protected subframe or the non-protected subframe in a predetermined cycle, and the CRS and the CSI-RS being reference signals; a measurement circuit that measures channel quality from the reference signals multiplexed individually on the protected subframe and the non-protected subframe; and a transmitter that notifies a base station apparatus of two types of channel quality information of the protected subframe and the non-protected subframe, measured by the measurement circuit.
