The WCDMA Air Interface
• Higher user peak data rates (several Mbps).
• Dynamic adaptation of user data rates (“bandwidth on demand”).
• Asymmetric uplink and downlink data rates to fit usual Packet-Switched (PS) traffic characteristics, e.g. web browsing, ftp downloads.
• Support of Quality of Service (QoS) differentiation, e.g. in terms of error rates and delay.
• Multiplexing of services with different quality and data rate requirements on a single connection.
• Improved spectrum efficiency (higher system throughput per unit of allocated frequency spectrum).
