User terminal, the processor and the communication control method

The user terminal according to the embodiment, performs a D2D communication is a communication directly between terminals, performs cellular communication with the base station. The D2D communication is performed using a portion of the uplink radio resource of the cellular communication. Said user terminal, when a timing advance value used to adjust the uplink transmission timing in said cellular communication is received from the base station, the timing advance value, the adjustment of the transmission timing in the uplink, the D2D communication a control unit that applies common to the adjustment of the transmission timing in. The control unit, using the scheduled radio resources by the base station as a radio resource of the D2D communication. .FIELD 9
