Many wireless operators are indeed rolling out 3G cellular networks to meet demand for data services; the cdma2000 systems has already been deployed in Asia and North America, and the WCDMA systems are gaining wider acceptance in Japan and started deployment in Europe. However, the prices for high-speed data service are still high. For inexpensive data service, the 3G systems must be evolved toward (1) increasing user data throughput and efficiency of the air interface while managing mobility in outdoor environment and (2) providing truly packet-switched air interface while allowing for concurrent services of voice and data. To address the demand, the two 3G standardization bodies responded with evolved 3G specifications, known as 1XEV-DV and HSDPA.

The 3G evolution aims at taking advantage of the interplay between physical layer technology (link adaptation and hybrid-ARQ) and MAC layer packet scheduling. However, an optimal design across physical and MAC layers opens many new system issues. To address these issues, this panel, consisting of experts in HSDPA and 1XEV-DV technologies, will discuss the following: (1) capacity and data throughput improvement: assessment methodology and predicted improvement; (2) the key enabling technologies: adaptive modulation-and-coding, hybrid-ARQ, packet scheduling, multiple antenna (multiplexing vs. diversity); (3) advanced receiver: interference cancellation, equalization; (4) radio access network technology: fast cell switching, packet routing; (5) inter-working between MAC-layer error control and link-layer error control; (6) TCP/IP over wireless packet channel, seamless roaming to/from WLAN. We expect that the discussions will give perspectives on fundamental issues and check common understanding between two different standards and between mobile and network equipment developers.
