Abstract: To enhance fairness between users with different data rate requirements in resource allocation process, this paper extends the proportional fair (PF) algorithm, proposes a packet scheduling algorithm for the third generation partnership project (3GPP) long term evolution (LTE) uplink systems. The algorithm allocates resources to users according to their data rate requirements. The weight factor in the algorithm updates in every scheduling process, so that users with high data rate requirement but in bad instantaneous channel state will not be allocated excessive resource. Simulation results show that the proposed algorithm has a better performance in fairness between different users than PF algorithm.
