Abstract

D2D (device to device, D2D) communication is one of the key technologies in 5G wireless networks, which is very effective in improving the network resource utilization and reducing the latency of proximity communication. However, D2D short-range communication technology can bring interference to cellular systems while improving spectrum resource utilization. In this paper, we propose a joint power control and channel selection communication resource allocation scheme with the aim of maximizing system throughput while reducing inter-user interference. First, all optimal transmit power finite sets are derived using convex function theory under the constraint of ensuring the QoS (quality-of-service, QoS) of system users; then, the classical KM (Kuhn-Munkres, KM) algorithm is used to match the best multiplexed subcarriers for D2D users to maximize the system throughput after multiplexing. The simulation results show that the proposed algorithm can effectively improve the system performance.
