TECHNOLOGY FOCUS

Wireless broadband internet access providing IP based services to mobile users is growing rapidly worldwide. 3GPP Long Term Evolution is the new UMTS standard making use of latest technologies such as OFDMA/SC-FDMA based access, frequency based scheduling, MIMO and higher order modulation. LTE promises to deliver peak data rates of up to 300Mbps in the downlink and up to 75Mbps in the uplink, as well as faster response through reduced latency while keeping deployment cost and terminal complexity at a low level. The scalable OFDM technology (ranging from 1.4MHz up to 20MHz) allows a flexible spectrum allocation in existing and new 3G frequency bands. LTE is the natural evolution of GSM/EDGE and UMTS/HSPA network technologies. 3GPP has completed the standardisation; extensive trials are under preparation while services are expected to start around 2010.

COURSE CONTENT

This course provides 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 introduces basic principles of the OFDM/SC-FDMA based physical layer and MIMO antenna technologies. Next different procedures as link adaptation, radio resource management as well as scheduling algorithms using the shared channel concept are introduced and related up- and downlink control signaling is looked at. The course also provides a short overview about the LTE architecture with the different network entities and interfaces of the Evolved Packet Core as well as the underlying QoS concept. The RRC, PDCP, RLC and MAC protocol are explained in detail with an overview about the various channels defined at the different layer. Eventually exemplary procedures are presented as initial access, connection setup, bearer configuration and handover.
