Abstract:
The blind decoding method disclosed herein is a blind decoding method to allow a user terminal to blind-decode downlink control information that is transmitted from a radio base station using at least one of a legacy PDCCH and an enhanced PDCCH that is frequency-division-multiplexed with a PDSCH, and includes the steps in which the radio base station reports information for configuring a number of candidates, which information is used to configure numbers of search space candidates for the legacy PDCCH and numbers of search space candidates for the enhanced PDCCH, to the user terminal, and the user terminal blind-decodes the downlink control information based on the numbers of search space candidates for the legacy PDCCH and the numbers of search space candidates for the enhanced PDCCH that are configured based on the candidate quantity configuration information.
