N2 - Power management and energy-aware communications systems have become increasingly important in mobile computing as well as mobile communications. In future wireless communication systems, the energy efficiency of terminals and base stations has to be improved significantly. Therefore, we propose a new utility function, which is the difference of the capacity and a weighted power cost term. The generally used individual power constraint is removed. Next, the utility region for single-antenna and multi-antenna multiple access channels is characterized. We show using basic principles that the single-input single-output (SISO) multiple-access channel (MAC) utility region is convex and provide a closed form expression for its Pareto boundary. We need the Pareto boundary to compute efficient operating points. Furthermore, the extension to multiple antenna channels is indicated by an iterative algorithm for weighted sum utility maximization in multiple-input single-output (MISO) and multiple-input multiple-output (MIMO) MAC. All discussed results are illustrated by numerical simulations.
