Energy-Efficiency Based Resource Allocation for the Scalar Broadcast Channel

Free registration required

Executive Summary

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.
