A method performed in a device-to-device (D2D) enabled device, for transmitting discovery signals for enabling D2D communication establishment in a cellular communication system is disclosed. The method comprises assigning, by a controller of the device, a time in a periodic time schedule and at least a subcarrier among a plurality of subcarriers assigned for carrier for D2D communication of the communication system based on a dynamic rule for spreading timing and/or subcarrier selection for the discovery signal. Furthermore, the method comprises transmitting, by a transceiver of the device, the discovery signal according to the time and subcarrier assignment provided by the controller. |
