Energy Efficient Non-Orthogonal Multiple Access for Machine-to-Machine Communications

This letter investigates an uplink energy minimization problem for machine-to-machine communications with non-orthogonal multiple access. To solve this non-convex problem, we first prove that transmitting with minimum rate and full time is optimal. Then, the original problem can be transformed into...
