Fair resource scheduling on UMTS WCDMA DSCH

Resource scheduling for NRT packet data traffic on the downlink shared channel (DSCH) of a UMTS WCDMA network is the focus of this work. A Fair Resource Scheduling (FRS) approach is proposed. The scheme takes into account link conditions to enhance throughput and provides fair resource sharing among traffic flows. FRS includes service priority handling during admission and scheduling to provide service class differentiation. The performance of the proposed scheduling discipline is analyzed through dynamic simulations and compared with the performance of simple round robin (RR) and link status aware (LSA) schemes. The analysis indicates that fair resource scheduling (FRS) provides the required throughput and delay performance for packet data over the WCDMA downlink while ensuring fair service to backlogged flows.
