TECHNOLOGY FOCUS

World-wide, there is a rapid growth in wireless broadband internet access providing IP-based services to mobile users. 3GPP Long Term Evolution is the new UMTS standard that makes use of the latest technologies such as OFDMA/SC-FDMA based access, frequency-based scheduling, MIMO and higher-order modulation. LTE is expected to deliver peak data rates of up to 300Mbps in downlink and up to 75Mbps in uplink as well as faster response through reduced latency whilst at the same time keeping deployment cost and terminal complexity on a low level. Scalable OFDM technology (ranging from 1.4MHz to 20MHz) allows flexible spectrum allocation in existing and new 3G frequency bands. 3GPP has completed standardization and first networks are in commercial operation.

COURSE CONTENTS

This course will provide participants with an overview of the LTE physical layer, the protocol and the architecture as defined in the 36 series of 3GPP specification Release 8. The course will introduce the basic principles of the OFDM/SC-FDMA based physical layer and MIMO antenna technologies. As a next step, various procedures such as link adaptation, radio resource management and scheduling algorithms using the shared channel concept will be introduced and related up and downlink control signaling will be looked at. The course will also provide a short overview of the LTE architecture with the various network entities and interfaces of the Evolved Packet Core as well as the underlying QoS concept. RRC, PDCP, RLC and MAC protocols wil be explained in detail.
