Abstract: In this paper, we propose a resource allocation scheme for managing interference in device to device (D2D) communication, aiming to address the issue of inter-user interference caused by the multiplexing of cellular network resources. The proposed scheme is based on K-means and Gale-Shapley stable matching algorithm. By analyzing the signal to interference plus noise ratio (SINR) formula, K-means clustering algorithm is used to group users, reduce the interference between users, and achieve multiple to one resource reuse. To improve communication system capacity and ensure fairness among users, GaleShapley stable matching algorithm is used to realize channel resource sharing within the user groups. Simulation results show that the system interference is reduced by 10% to 30% compared to the greedy graphical coloring resource allocation algorithm, while maintaining stable system capacity.
