METHOD FOR TERMINAL CLUSTERING IN WIRELESS COMMUNICATION SYSTEM SUPPORTING DEVICE-TO-DEVICE COMMUNICATION AND APPARATUS THEREFOR

摘要

A method for terminal clustering in a wireless communication system which supports device-to-device communication and an apparatus therefor are disclosed. Particularly, a method for performing terminal clustering by a terminal in a wireless communication system which supports device-to-device (D2D) communication may comprise the steps of: determining an initial preference value; determining an initial preference triplet by performing an affinity propagation (AP) technique while increasing or decreasing the initial preference value; updating the preference triplet through a golden section search (GSS) technique on the basis of the initial preference triplet; determining, from the updated preference triplet, a final preference value for minimizing the energy consumption of all terminals; and determining a head terminal and member terminals belonging to the head terminal by performing the AP technique using the final preference value.
