Power Control and Resource Allocation for Device-to-Device Communications in Cellular Networks

Device-to-device (D2D) communications in cellular networks will improve traditional cellular systems in many ways. By allowing user equipment (UE) in proximity to communicate through direct links, the transmitter would be able to transmit with lower power while the receiver could still receive better-quality signals. Both spectrum and energy eciency can be signicantly increased. Moreover, D2D comm…
