摘要：
The present invention is designed to transmit and receive reference signals adequately even when the abundance ratio of reference signals in a predetermined period is increased. The present invention provides a base station apparatus that transmits CSI-RSs to the first mobile terminal apparatus which can receive CSI-RSs and to a second mobile terminal apparatus which can receive CSI-RSs that are set in a predetermined period at a lower abundance ratio than the first mobile terminal apparatus, and this base station apparatus allocates CSI-RSs to CSI-RS resource which can be muted at an abundance ratio which allows the first mobile terminal apparatus reception, reports the resources where CSI-RSs are allocated to the first mobile terminal apparatus, and, upon reporting the resources where CSI-RSs are allocated to the second mobile terminal apparatus, reports part of the resources as muted resources.
