Abstract
The present invention makes it possible to transmit and receive CSI-RSs adequately even when the number of CSI-RSs increase following the increase of antennas. The present invention provides a base station apparatus (20) that transmits CSI-RSs to a mobile terminal apparatus (10A) which is capable of receiving CSI-RSs for channel state measurement from a plurality of antennas and to a mobile terminal apparatus (10B) which is capable of receiving CSI-RSs from a smaller number of antennas than the mobile terminal apparatus and this base station apparatus has a CSI-RS allocation section (211) which allocates CSI-RSs for the number of antennas which the mobile terminal apparatus (10A) supports to radio resources and a transmitting/receiving section which reports to the mobile terminal apparatus (10A) the resources where the CSI-RSs are allocated and which upon reporting the resources where CSI-RSs are allocated to the mobile terminal apparatus (10B) reports part of the resources as resources to be muted.
