Abstract

In WCDMA, uplink radio resources are shared by multiple users and the radio resource management (RRM) is done at the UTRAN (UMTS Terrestrial Radio Access Network). In this paper, the link and system performance of the WCDMA uplink is evaluated using different techniques such as retransmissions with incremental redundancy (IR), short frame durations and fast scheduling. It is seen that the radio link efficiency can be improved using IR, while the traffic delays can be reduced and cell throughput can be enhanced by using fast scheduling and short frame durations.
