13. A mobile communication system, which 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, comprising:
-
a D2D communication terminal that is a user terminal which performs the D2D communication; and a base station that assigns a radio resource to be used in the D2D communication to the D2D communication terminal, wherein in response to detection of interference power, the D2D communication terminal transmits interference information on interference to the base station. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
