WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD

摘要

To improve the channel estimation accuracy of "DL grant" that instructs data allocation of a downlink of R-PDCCH. A wireless communication apparatus according to an aspect of the invention includes a receiver that is configured to receive a control signal, and a blind decoder that is configured to perform a blind decoding of a plurality of adjacent physical resource blocks (PRBs) in which the same precoding is used in a unit of an RB group (RBG) that is composed of the plurality of PRBs, and to detect a resource area to which a control signal for the wireless communication apparatus that is included in the control signal is allocated.
