Abstract: The invention relates a user communication device for cellular communication with a base station and D2D communication with at least one user communication device. The user communication device comprises: a communication interface configured for cellular communication with the base station and D2D communication via a D2D communication channel between the user communication device and the user communication device, the D2D communication with the further user communication device comprises receiving channel state information from the further communication device, the channel state information comprises channel state information of a cellular communication channel between the further user communication device and the base station; and a processor configured to adapt a feedback vector on the basis of a quality measure of the D2D communication channel between the further user communication device and the user communication device and to provide information about the adapted feedback vector via the communication interface to the base station.
