BASE STATION APPARATUS, MOBILE TERMINAL APPARATUS AND COMMUNICATION CONTROL METHOD

摘要

This invention is directed to provision of a base station apparatus, a mobile terminal apparatus and a communication control method whereby a control that is applicable to interferences in a heterogeneous network can be performed and the next generation mobile communication system can be supported. An offset is added to the reception power of a signal transmitted from a base station apparatus (B1) of a picocell (C1) to a mobile terminal apparatus (UE), so that the reception power to which the offset has been added becomes greater than the reception power of a signal transmitted from a base station apparatus (B2) of a macrocell (C2) to the mobile terminal apparatus (UE), with the result that it becomes possible to determine, from among mobile terminal apparatuses (UE) belonging to the picocell (C1), the mobile terminal apparatus (UE) for which the reception power of the signal transmitted from the base station apparatus (B2) to the mobile terminal apparatus (UE) is greater than the reception power of any other signal transmitted to the mobile terminal apparatus (UE). This determined mobile terminal apparatus is scheduled in accordance with a blank resource established in a downstream radio frame of the base station apparatus (B2).
