    Abstract: 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.

    Abstract: Provided are methods for transmitting and receiving uplink data, a user equipment and a base station. The method for transmitting uplink data by a user equipment includes: transmitting to a base station a scheduling request (SR); receiving, from the base station, an uplink grant indicating scheduling information for transmitting uplink data, wherein the scheduling information is allocated by the base station according to a volume of the uplink data, the volume being determined by the SR; and transmitting to the base station the uplink data by employing the scheduling information. In this way, the present invention reduces power consumption and time delay during an uplink data transmission process.
