Abstract
Abstract The power distribution of terminal direct communication (D2D communication) in 5G communication technology is a hot topic in recent research. In order to improve system capacity and spectrum utilization, this paper combines millimeter wave and D2D communication technology, which is aimed at 28GHz frequency band uplink. The D2D resource allocation in the road and downlink cellular networks is studied, and the total system throughput is maximized to optimize the algorithm. First, the admission set corresponding to each D2D pair is derived. Secondly, considering the power control of each D2D to the user and the cellular user, the throughput in the uplink and downlink is respectively determined. Finally, the D2D is guaranteed. The cellular user channel is assigned to the D2D pair on the premise of maximizing the total throughput. On the surface of the simulation results, the proposed scheme can significantly improve the throughput of the system.
