Abstract:
The invention relates to a method (20) in a device-to-device, D2D, enabled user equipment (12) of a communication system (10). The D2D enabled user equipment (12) supports D2D-communication with another D2D-enabled user equipment (15). The communication system (10) comprises a base station (15) serving one or more cellular user equipment (14) unable to support D2D communication. The D2D enabled user equipment (2, 15) and the cellular user equipment (14) share the same communication resources. The method (20) comprises: receiving (21), from the base station (13), configuration parameters comprising information on a reference signal pattern for use by the D2D enabled user equipment (12), and transmitting (22), based on the configuration parameters, cellular reference signals, enabling the cellular user equipment (14) to measure and report, to the base station (13), channel information on a channel from the D2D enabled user equipment (12) to the cellular user equipment (14). The invention also relates to D2D user equipment, methods in a base station, base station, computer programs and computer program products.
