Abstract :
The first step of evolving WCDMA towards higher data rates is discussed. It is shown how techniques such as fast link adaptation, fast hybrid ARQ and fast scheduling, among others, can be applied to WCDMA, leading to increased throughput, lower delays, and downlink peak rates in the order of 10 Mbit/s. Through system simulations, the packet-data performance of such an evolved WCDMA system is illustrated
