Abstract
A method in a first user equipment for adjusting a beacon signal to be detected by at least one second user equipment in a wireless telecommunications network is provided. The beacon signal is transmitted in order to enable an establishment of Device-to-Device, D2D, communication between the first user equipment and the at least one second user equipment. The method is characterized in that the method comprises adjusting, prior to transmitting the beacon signal, the transmit power of the beacon signal based on a requirement of an application in the first user equipment for which the D2D communication is to be established.A user equipment, a network node, and a method in a network node for enabling a D2D communication between a first user equipment and at least one second user equipment are also provided.
