This paper intends to adopt interference alignment (IA) for improving the energy efficiency (EE) of both the device-to-device (D2D) and cellular links in a D2D multiple-input and multiple-output (MIMO) downlink underlaying cellular network. Due to the strong cross-tier interference, the EE optimization problem becomes NP-hard and computationally difficult… CONTINUE READING
