Underlay in-band device-to-device (D2D) multicast communication, where the\nsame content is disseminated via direct links in a group, has the potential to\nimprove the spectral and energy efficiencies of cellular networks. However,\nmost of the existing approaches for this problem only address either spectral\nefficiency (SE) or energy efficiency (EE). We study the tradeoff between SE and\nEE in a single cell D2D integrated cellular network, where multiple D2D\nmulticast groups (MGs) may share the uplink channel with multiple cellular\nusers (CUs). We formulate the EE maximization problem with constraint on SE and\nmaximum available transmission power. A power allocation algorithm is proposed\nto solve this problem and its efficacy is demonstrated via extensive numerical\nsimulations. The tradeoff between SE and EE as a function of density of D2D\nMGs, and maximum transmission power of a MG is characterized.\n
