Downlink Resource Allocation and Power Control for Device-to-Device Communication Underlaying Cellular Networks

This letter investigates the resource allocation and power control for both device-to-device (D2D) pairs and cellular users (CUs) in D2D communication underlaying single-cell cellular networks, where multiple D2D pairs can share the same resources with CUs. Our goal is to maximize the sum rate of D2D pairs subject to the rate requirements for all CUs and power requirements for both D2D pairs and the base station. We first give the optimal conditions for the resource allocation of D2D pairs and power control of CUs and then propose an iterative resource allocation and power control algorithm. Numerical results show that the proposed algorithm achieves higher sum rate of D2D pairs than the existing schemes.
