1. A first base station, comprising:
a reception unit configured to receive information indicating whether data to be transmitted from a second base station to a terminal exist from the second base station, when the data to be transmitted to the terminal are distributed by the second base station; and
a control unit configured to perform discontinuous reception (DRX) control for the terminal, when information indicating the data to be transmitted from the second base station to the terminal exist is received,
wherein the information indicating whether the data to be transmitted from the second base station to the terminal exist is represented by one bit and is transmitted being attached to the data to be distributed by the second base station, and
wherein the control unit is further configured to control transmission of downlink control information to prevent the terminal from transitioning to a DRX state.
