The present invention is designed to prevent the decrease of capacity even when the ratio of uplink subframes and downlink subframes is changed in each component carrier in TDD carrier aggregation. With the radio communication method according to the present invention, a radio base station apparatus generates a downlink control channel signal containing downlink control information including carrier indicator field information, and transmits the downlink control channel signal to a user terminal, and the user terminal receives the downlink control channel signal and executes signal processing with respect to the downlink signal in accordance with the downlink control information. In this case, the carrier indicator field information is information which associates a carrier index and the number of subframes to schedule victim subframes. |
