    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: User equipment, apparatus and method perform dual connectivity with a first base station acting as a master base station and a second base station acting as a secondary base station, transmit to the master base station capability information indicating that the user equipment supports a function of skipping a random access procedure, and receive from the master base station, a message instructing to change the secondary base station from the second base station to a third base station. The message includes information indicating that random access procedure for the third base station is skipped and an including an uplink grant indicating radio resources allocated by the third base station and a timing advance (TA) value to be applied to an uplink transmission to the third base station. The user equipment transmits the uplink transmission to the third base station by using the uplink radio resources indicated by the uplink grant.
