Description

This course provides a comprehensive technical overview of the structure and operation of the UMTS air interface protocol stack. Detailed description of WCDMA FDD technology and its use in UMTS networks. We will dedicatedly learn the basics of UMTS air interface in detail. In doing so, we are covering the Frequency Bands: ITU Regions. Mobile Frequencies.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 AttributesPower 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 UMTS in 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 ProcedureSynchronization and Random Access: Downlink Timing, Cell Search Procedure, and Random Access.Idle Mode: PLMN Selection, Cell Selection and Reselection, System Information, Mobility Management, Paging, Cell Reselection between GERAN and UTRAN.Handover: Cell Sets and Measurements, Soft/Softer Handover, Events, Signalling, Time Offset, Handover between GERAN and UTRAN, Hard Handover.
