Abstract: Efficient radio resource allocation algorithm is proposed in this paper. Proportional fair algorithm gives favorable performance compared to two classical algorithms max-C/I and RR. But PF algorithm does not consider QoS parameters while allocating resources to the users. Moreover with less transmission power utilization Fairness disappears in PF algorithm. A PFQoS-Centric is proposed in this paper. PFQoS-Centric gives better performance. In this proposed algorithm Data rate fairness and Allocation Fairness increase with increase in time jitter threshold values or increase in number of active users increases. Thus Data rate fairness and Allocation fairness is becoming more as compared to that of proportional algorithm. Here Throughput is also maintained during increase in fairness. QoS parameters like Data rate Fairness, Allocation Fairness Delay is most important for next generation of mobile communication. Propose Algorithm (PFQoS-Centric) gives guarantee to satisfy the QoS parameters.
