Abstract
Method for D2D communication in a wireless device comprising receiving a D2D communication from another wireless device, the D2D communication comprising a first detection sequence of a plurality of detection sequences. Each detection sequence is associated with a respective different radio access technology or service type so that the first detection sequence identifies a radio access technology or service type associated with the D2D communication. The method also comprises selecting a transmission procedure for a D2D transmission from the second wireless device based on the first detection sequence, and performing the D2D transmission using the selected transmission procedure.
