چکیده
WCDMA, Packet data, HSDPA In this paper, the first step of evolving WCDMA beyond IMT-2000 is outlined and elaborated upon. 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 for best-effort services, lower delays, and downlink peak rates in the order of 10 Mbit/s. The end-to-end protocol architecture is discussed, and using protocol simulations the benefit of having a hybrid type II ARQ scheme in Node B is shown.

Today, 84% of all reported global cellular subscribers make calls via radio access technology specifi ed by the Third Generation Partnership Project (3GPP). This signifi es that WCDMA is the predominant thirdgeneration (3G) radio network technology, and as such, represents a substantial economy of scale. In addition, the recent introduction of high-speed packet access (HSPA, 3GPP Release 6) has...
