Abstract [en]

Network-assisted Device-to-Device (D2D) communicationis a promising technology for improving the performanceof proximity-based services. This paper demonstrates how D2Dcommunication can be used to improve the energy-efficiencyof cellular networks, leading to a greener system operationand a prolonged battery life of the mobile devices. Assuminga flexible TDD system, we develop optimal mode selectionpolicies for minimizing the energy cost (either from the systemor from the device perspective) while guaranteeing a certainrate requirement. The jointly optimal transmit power and timeallocation, as well as the optimal mode selection, is found bysolving a small convex optimization problem. Special attentionis given to the geometrical interpretation of the obtained results.We show that when network energy is the primary concern, D2Dmode is preferable in a large portion of the cell. When the deviceenergy consumption is most important, on the other hand, thearea where D2D mode is preferable shrinks and becomes close tocircular. Finally, we investigate how network parameters affectthe range where direct communication is preferred.
