Abstract
Provided is a relay station that is capable of improving PDSCH channel estimation accuracy, even in a case where a DL grant is provided that gives instructions for downlink data allocation for R-PDCCH. In this device, a signal separation unit (203) receives, of the control information and data and reference signals sent from a base station (100), the reference signals disposed in a first region and a second region within a pre-coding RB group (PRG) comprising one or more PRBs of the plurality of PRBs constituting a divided frequency region; the control information disposed in the first region; and the data disposed in the second region. A demodulation unit (204) demodulates the data on the basis of the reference signals. The demodulation unit (204) demodulates the data using the reference signals disposed in the second region.
