Spectrum-Aware Energy Efficiency Analysis in <i>K</i>-tier 5G HetNets

In future multi-tier cellular networks, cognitive radio (CR) compatible with device-to-device (D2D) communication can be an aid to enhance system spectral efficiency (SE) and energy efficiency (EE). Users in proximity can establish a direct connection with D2D communication and bypass the base stati...
