Abstract

Device-to-Device (D2D) communication appears to be a promising component in 5G networks because of its increased spectral efficiency and reduced communication delay. But it also causes the co-channel interference to cellular networks. In this paper, we propose a new power control and resource scheduling scheme by taking into account the fairness, quality-of-service (QoS) requirements to deal with the issue of co-channel interference. The objective of our work is to maximize the sum of all users logarithmic utility functions. This is a NP-hard problem. We decomposed the optimization problem into two main subproblems. The first one is the problem of power control for a single D2D pair and its possible reuse candidates to maximize the overall throughput while ensuring signal-to-noise-and-interference (SINR) requirements of both D2D pair and its reuse candidates. The second one is the problem of Proportional Fair Scheduling (PFS) of resource for multiple D2D pairs and cellular users with a view to improving the system Fairness. We propose to use the Hungarian algorithm to address this issue. Simulation results showed that the proposed algorithm could significantly improve the system performance in terms of the system fairness and the overall system throughput while satisfying the QoS requirements of both D2D and cellular links.
