Abstract :
The 3G UMTS is currently undergoing inherent changes. The expected release 5&6 of UMTS will contain a new set of features known collectively as high speed downlink packet access (HSDPA). In this paper, we propose two packet scheduling algorithms for HSDPA, shortest queue first (SQF) and longest queue first (LQF), to provide priority scheduling between services of different quality of service (QoS) classes and fairness between users within the same class. Simulation results show that the proposed algorithms meet QoS requirements of different traffic classes, with the SQF algorithm having a better performance compared to the LQF algorithm.
