A Novel Radio Resource Management Approach for QoS Provisioning in Multi-Service Multi-Slot OFDMA Systems

In this paper, we propose a novel and efficient OFDMA radio resource management approach based on standard Linear Programming theory. Our approach overcomes the drawbacks of previously proposed algorithms by considering multiple service scenarios, multiple quality of service (QoS) parameters and use of multiple time slots per frame. Further, the algorithm has a considerably low complexity and is shown to be a generalization of many previously proposed algorithms. System simulations show that by using the proposed approach, the system performance is considerably enhanced.
