Abstract: The present invention is designed to reduce the decrease of uplink throughput in the event a user terminal connects with a plurality of radio base stations. A user terminal (20) according to an example of the present invention provides a user terminal to connect with a plurality of radio base stations including at least a first radio base station and a second radio base station, and this user terminal has a PH report generating section (411) that calculates the PH (Power Headroom) of each radio base station and generates PH reports, and a transmission section (203) that transmits either the PUSCH (Physical Uplink Shared Channel) bandwidth of the first radio base station, a PH report per resource block, or information about the transmission power density, and a PH report for the first radio base station, to the second radio base station.

Abstract: The present invention is designed so that, in a radio communication system in which a plurality of component carriers (CCs) are used in each small cell within a macro cell, the load of measurements, the amount of information to report and so on in user terminals are reduced. The macro base station of the present invention transmits, to a user terminal, measurement indication information that includes a measurement indication for the received power of a measurement signal of a specific CC in each small cell, and receives, from the user terminal, a measurement report that includes the received power of the measurement signal of the specific CC. Also, the macro base station calculates the received quality of the measurement signals of the plurality of CCs based on the received power of the measurement signal of the specific CC.
