Joint Resource Allocation and Mode Selection for Device-to-Device Communication Underlying Cellular Networks

Device to device (D2D) communication has recently been established in the literature as an effective means increase frequency spectrum and enhance efficiency of energy consumption future cellular systems. However, certain issues, resulting from reusing resources same cell, have caused serious perturbations. We study issues pertaining D2D communication, such dual mode selection, channel allocation power control, aiming at maximization overall throughput system, while time ensuring that generated interference is kept minimized. This NP-Hard problem decomposes optimization into two layers: inner layer, where DQN algorithm used indicator optimal transmission should be allocated pairs accordance with their operation, outer strategic decisions, which use how allocate channels, are made. proved superiority proposed scheme, terms both system performance, through simulating experiments involving different scenarios.
