摘要

To provide a base station (eNB 2) including a scheduler (35) that monitors radio resources of each UE relevant to cellular communication in which CUEs (3A) perform radio communication via the base station itself and D2D communication in which DUEs (3B) directly perform radio communication without via the eNB. Further, when the DUE to be controlled shares the same radio resources with the CUE, the scheduler sets a control flag for controlling a transmission power amount in the D2D communication to ON, with respect to the DUE that performs the D2D communication. The scheduler also notifies to the DUE to be controlled by a DCI format added with a control flag. When the received control flag is ON, each DUE controls the transmission power so that the transmission power amount in the D2D communication becomes equal to or less than a threshold.
