Abstract  Abstract

PROBLEM TO BE SOLVED: To properly transmit/receive a CSI-RS even when the number of the CSI-RSs increases depending on increase in the number of antennas.

SOLUTION: A base station device (20) transmitting CSI-RSs to a mobile terminal device (10A) which can receive CSI-RSs for measuring channel status from a plurality of antennas and to a mobile terminal device (10B) which can receive the CSI-RSs from antennas where the number of the antennas is smaller than that of the mobile terminal device (10A) comprises: a CSI-RS allocation part (211) allocating the CSI-RSs for the number of the antennas handled by the mobile terminal device (10A) to radio resources; and a transmission/reception part notifying the mobile terminal device (10A) of the resources to which the CSI-RSs are allocated and notifying the mobile terminal device (10B) that part of the resources are resources to be muted in notifying of the resources to which the CSI-RSs are allocated.
