Energy- and Spectral-Efficiency Trade-Off for D2D-Multicasts in Underlay Cellular Networks
Energy- and Spectral-Efficiency Trade-Off for D2D-Multicasts in Underlay Cellular Networks
Underlay in-band device-to-device (D2D) multicast communication, where the same content is disseminated via direct links in a group, has the potential to improve the spectral and energy efficiencies of cellular networks. However, most of the existing approaches for this problem only address either spectral efficiency (SE) or energy efficiency (EE). …
