    IPC: H04W8/24

    Abstract: A terminal is disclosed that includes a processor that includes, in capability information, a separation class indicating a frequency separation between a lower edge of a component carrier with a lowest frequency for supported intra-band non-contiguous carrier aggregation and an upper edge of a component carrier with a highest frequency for the supported intra-band non-contiguous carrier aggregation. The terminal further includes a transmitter that transmits the capability information to a base station, where the separation class is indicated by an index to identify a class of the frequency separation. In other aspects, a transmission method and a radio communication system are also disclosed.

    Abstract: The present invention is designed so that, when a user terminal connects with a plurality of radio base stations, the decrease of uplink throughput is reduced. A user terminal according to an example of the present invention provides a user terminal (20) that connects with a plurality of radio base stations (10) including a first radio base station and a second radio base station, and this user terminal has a transmission section (203) that transmits uplink signals to each radio base station, a receiving section (203) that receives terminal-specific information with respect to the first radio base station, related to the maximum transmission power of the uplink signals, and a maximum transmission power setting section (406) that sets the maximum transmission power for the first radio base station based on the terminal-specific information with respect to the first radio base station.

    Abstract: A technique is provided that is for efficiently avoiding interference that occurs due to simultaneous communication with different radio systems. An aspect of the present invention relates to user equipment including a cellular communication controller that controls first radio communication with a cellular system, and a different radio system communication controller that controls second radio communication with a different radio system other than the cellular system, wherein the cellular communication controller reports, to the cellular system, interference notice indicating interference between the first radio communication and the second radio communication, based on information obtained in the first radio communication.
