SYNCHRONIZATION METHOD FOR A DEVICE-TO-DEVICE DISCOVERY AND/OR A DEVICE-TO-DEVICE COMMUNICATION, USER EQUIPMENT, AND SYNCHRONIZATION CONTROL UNIT

摘要

To attain a synchronization for a device-to-device discovery and/or a device-to-device communication, a user equipment determines whether it is enabled to transmit a synchronization signal (65) for the device-to-device discovery and/or the device-to-device communication. The user equipment has a wireless interface configured for communication with a radio access network of a mobile communication network. The user equipment selectively transmits the synchronization signal (65) for the device-to-device discovery and/or the device-to-device communication over the wireless interface to at least one further user equipment.
