## Abstract

Device to Device (D2D) communication underlying cellular communication can improve the utilization efficiency of resources, and the cellular user equipment (C-UE) can utilize the rental resources for D2D user equipment (D-UE) to obtain revenue. In 5g communication, non-orthogonal multiple access (NOMA) is another promising technology. In this paper, cellular users can choose to apply orthogonal multiple access (OMA) mode or NOMA mode to rent their own resources to get the maximum benefit. We proposed a dual-arm bandit machine model to solve this mode selection game and proved the effectiveness of our scheme through simulation results.
