Abstract: A radio communication system is provided with a high-power base station, a radio terminal which is located within a macro cell formed by the high-power base station, and a low-power base station which has a lower transmission output power than the high-power base station. The low-power base station sends, to the high-power base station, control information needed for the radio communication between the radio terminal and the low-power base station; the high-power base station sends, to the radio terminal, the control information received from the low-power base station; and the radio terminal performs radio communication with the low-power base station by using the control information received from the high-power base station.

Abstract: A UE 100-1 and a UE 200-2 perform D2D communication that is direct device to device communication. The UE 100-1 transmits a D2D termination preliminary notification indicating that termination of the D2D communication is wished to the UE 100-2 during the D2D communication. The UE 100-1 terminates the D2D communication after transmitting the D2D termination preliminary notification.

Abstract: A mobile communication system supports cellular communication in which data communication is performed between a network and a user terminal and D2D communication in which data communication is directly performed among two or more user terminals. The D2D communication is performed by using a part of the uplink radio resources of the cellular communication. The uplink radio resources include a specific radio resource that is used in the transmission of a predetermined uplink signal in the cellular communication. The use of the specific radio resource in the D2D communication is regulated.

Abstract: When a UE 100-2 (a reception-side UE) that performs D2D communication by using UL radio resource switches communication modes between cellular communication and the D2D communication, if DL subframe in which data reception of the cellular communication should be performed and the UL subframe in which data reception of the D2D communication should be performed at least partially overlap on a time axis, then the UE 100-2 performs data reception in one subframe, out of the overlapping two subframes.

Abstract: A mobile communication system comprises: a user terminal that receives a desired wave signal from a serving cell while receiving an interference wave signal from a neighboring cell adjacent to the serving cell; and a base station that manages the serving cell. The base station comprises: a controller that generates an interference replica signal corresponding to the interference wave signal and superposes the interference replica signal on the desired wave signal; and a transmitter that transmits the desired wave signal superposed with the interference replica signal to the user terminal. The controller generates the interference replica signal such that the interference replica signal cancels the interference wave signal in a location of the user terminal. The interference replica signal acts as a disturbing signal, which disturbs demodulation of the desired wave signal, in a location other than the location of the user terminal.
