WCDMA uplink enhancements for high-speed data access

To meet future demands for improved uplink packet data performance, enhancements to the WCDMA uplink are part of Re16 of the specifications, with completion date at the end of 2004. The main targets are improved performance for packet data services in terms of reduced delays, improved availability of high data rates, and improved capacity. The paper gives an overview of the design targets, the basic principles, and how they are integrated into WCDMA. Simulation results are used to exemplify the performance gains brought by introducing these enhancements into WCDMA.
