There is provided a method and user equipment (UE) for supporting device to device (D2D) communication, for example side link communication, of wireless devices. At least one of the source UE or the destination UE is out of synchronization. Side link (SL) communication information (e.g. SL sync signal, SL timing request message, SL-data, special sync signal) may be blindly and repeatedly transmitted until the source UE receives a response from the destination UE.
