Until recently, link adaptation and resource allocation for communication system relied extensively on the spectral efficiency as an optimization criterion. With the emergence of the Energy Efficiency (EE) as a key system design criterion, resource allocation based on EE is becoming of great interest. In this paper, the authors propose an optimal EE-based resource allocation method for the Scalar Broadcast Channel (BC-S). They introduce their EE framework, which includes an EE metric as well as a realistic power consumption model for the base station, and utilize this framework for formulating their EE-based optimization problem subject to a power as well as fairness constraints.
