Abstract :
This paper addresses the problem of efficient scheduling of packet data users in a W-CDMA network. Two simple, centralised algorithms are described for the uplink, and their performance illustrated in the case of the FDD mode of UMTS, for a delay-tolerant service. Both algorithms are centralised schedulers that attempt to manage tightly the interference power in each cell. Simulation results illustrate the performance (delay, throughput) one might expect from such a system
