1. A user communication device arranged to support grouping of user communication devices in a communication network, wherein the user communication device is configured to communicate with further user communication devices in the communication network via a device-to-device (D2D) communication, and wherein the user communication device is additionally configured to communicate with the further user communication devices via a communication network device, wherein the user communication device comprises at least one processor, wherein the at least one processor is configured to couple with a memory, read an instruction in the memory, and execute the following when supporting the grouping of user communication devices in the communication network:
determining a neighbor user communication device set comprising the user communication device and neighbor user communication devices, wherein the neighbor user communication devices are arranged to communicate in the communication network, and wherein the neighbor user communication devices are adjacent to the user communication device in the communication network; and
determining, by causing a transceiver to communicate with the neighbor user communication devices of the neighbor user communication device set via the D2D communication, among user communication devices of the neighbor user communication device set a user communication device group that the user communication device joins, wherein information on the user communication device group is provided to the communication network device, wherein the information on the user communication device group comprises a group aggregate covariance matrix, in which covariance matrixes of the user communication devices of the user communication device group are aggregated, and wherein each covariance matrix is a covariance matrix of a downlink channel between the respective user communication device of the user communication device group and the communication network device.
