Abstract
Interference suppression by beam forming is achieved even in an FDD (Frequency Division Duplex) system. A base station deviceperforms communication based on FDD. The base station deviceincludes a downlink signal reception unitthat receives a downlink signal transmitted from another base station device. The base station deviceperforms a beam forming process for directing a null beam to an arrival direction of the downlink signal from the another base station device, by using transmission path information between the base station device and the another base station device, the information being available from the downlink signal received by the downlink signal reception unit
