The present disclosure relates to user communication devices and communication network devices, both arranged to support grouping of user communication devices in a communication network. One example user communication device determines a neighbor user communication device set comprising the user communication device and neighbor user communication devices, and determines, by communicating with the neighbor user communication devices of the neighbor user communication device set via D2D communication, a user communication device group that the user communication device joins. The communication network device receives information on a plurality of user communication device groups, determined by user communication devices in the communication network, and executes clustering on the plurality of user communication device groups.

Devices and methods arranged to support user communication device grouping in a communication network

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.
