Abstract
Even if the number of CSI-RSs increases with the increase of antennas, the CSI-RSs are properly transmitted and received. The mobile terminal device 10A capable of receiving CSI-RS for measuring channel conditions from a plurality of antennas, and the mobile terminal device 10B capable of receiving CSI-RS from a smaller number of antennas than the mobile terminal device. In the base station apparatus 20 for transmitting an RS, a CSI-RS allocator 211 for allocating CSI-RSs corresponding to the number of antennas corresponding to the number of antennas by the mobile terminal apparatus 10A to the radio resource, and the mobile terminal apparatus 10A. ), A transmission / reception unit for notifying a resource to which the CSI-RS is allocated, and for notifying the mobile terminal device 10B of a resource to which the CSI-RS is allocated, notifies a part of the resource as a muted resource. .
