• UMTS Bands - WCDMA: Multiple Access, Duplex Division, 3G Radio Spectrum, WCDMA Overview, Main Principles, Advantages and Problems, Spreading Process, Channellisation, Scrambling, Filtering, and Modulation, Code Requirements, frame structure in UMTS.

• Quality of Service: QoS Architecture, UMTS QoS Classes, Sources of Service Attributes, UMTS Bearer Service Attributes, RAB Service Attributes, Radio Bearer Service Attributes, RAN Access, and CN Bearer Service Attributes

• Power Control: Open-loop Power Control, Inner-loop Power Control, Outer-Loop Power control, Power Control in Soft Handover.

• Multipath Propagation: Short- and Long-time Delay Profile, Rake Receiver, Downlink Open-loop Transmit Diversity, Downlink Closed-loop Transmit Diversity.

• Modulation Techniques and Coding: Basic Modulation Techniques, UMTS Modulation, Adaptive Modulation and Coding.

• Channel structure of UMTSin uplink and downlink both- Logical, Transport & physical Channels and their mapping, Description, and also understand the functionality of every channel.

• RRC States In UMTS; Architecture and Procedure

• Synchronization and Random Access: Downlink Timing, Cell Search Procedure, and Random Access.
