Control method for device-to-device communication

A control method for device-to-device (D2D) communication between a first piece of user equipment (UE) present in a first cell and a second piece of UE present in a second cell, comprising:

• measuring, at each of a first base station managing the first cell and a second base station managing the second cell, a cell load of the base station;
• exchanging, at the first base station and the second base station, the cell load information for D2D communication;
• selecting, at each of the first base station and the second base station, any one of an overlay-based resource allocation method and an underlay-based resource allocation method on the basis of the measured cell load of the base station;
• and
• allocating, at each of the first base station and the second base station, resources on the basis of the selected resource allocation method.

A control method for device-to-device (D2D) communication performed in a base station, comprising:

• receiving location information about each piece of user equipment (UE) from a plurality of pieces of UE;
• performing power control for D2D communication on the basis of the location information about the respective pieces of UE;
• and
• transmitting power control information to pieces of D2D communication UE that are pieces of UE between which a D2D communication link will be set among the plurality of pieces of UE.
