Abstract

The purpose of the present invention is to enable adjustment of the number of blind decoding operations, by enabling a suitable number of search space candidates to be set for when expanded PDCCH are used in addition to existing PDCCH. This blind decoding method whereby a user terminal blind decodes downlink control information sent from a wireless base station device by using at least either existing PDCCH or expanded PDCCH that are frequency-division multiplied with PDSCH, has: a step in which the wireless base station notifies the user terminal of the candidate number setting information used for setting the number of search space candidates for existing PDCCH and the number of search space candidates for the expanded PDCCH; and a step in which the user terminal blind decodes the downlink control information, on the basis of the number of search base candidates for the existing PDCCH and the number of search space candidates for the expanded PDCCH, set on the basis of the candidate number setting information.
