D2D, communication between the first user equipment and the at least one second user equipment,
characterized in that the method comprises
determining a requirement of an application in the first user equipment for which the D2D communication is to be established;
and

adjusting, prior to transmitting the beacon signal, the transmit power of the beacon signal based on the requirement,
wherein the requirement comprises a required data transfer rate of the application.
