WCDMA evolved - high-speed data access

To meet future demands for improved uplink packet data performance, WCDMA is continuously evolving. In Rel5, HSDPA was introduced, providing substantial downlink improvements, and in Rel6, the enhanced uplink will be an integral part of the specifications. The paper describes the principles behind HSDPA and enhanced uplink and how they are integrated into WCDMA. Simulation results exemplify the performance gains possible.
