Improved Joint Resource and Power Allocation Algorithm with QoS Provisioning

Abstract

This work revisits the resource and power assignment problem of maximizing the spectral efficiency of a wireless system subject to user satisfaction constraints in multi-service scenarios. Two limitations of the state-of-the-art solution are shown, which are: 1) the use of estimated throughput to determine the priority between user equipments; and 2) infeasible solutions are not treated. Thus, two improvements to deal with those limitations are proposed without increasing the computational complexity. Simulation results show that the algorithm with the proposed improvements achieves better performance and deals with infeasible solutions.
