heal.abstract In this letter, the problem of optimal joint uplink power and subcarrier allocation in single-carrier frequency-division multiple access wireless networks with real-time services is addressed, via the introduction and adoption of a utility-based framework. A joint optimisation power and subcarrier allocation problem is formulated and the optimal power allocation is determined, while an iterative algorithm to realise the joint allocation is presented. Finally, numerical results are provided that demonstrate the effectiveness of the proposed approach in terms of power savings and user satisfaction. © 2011 Taylor & Francis. en
