Course outline:

Introduction to LTE Advanced

● Evolution path of 3GPP LTE systems (standardization time plan in 3GPP)
● Features of LTE releases
● Requirements and performance targets of LTE Advanced and its relation to requirements of IMT Advanced for 4G systems
● Identified IMT-Advanced spectrum allocations
● Release 8 and 9 air interface features

EPS Network Architecture Improvements

● Release 8 nodes and interfaces (UE, eNB, MME, SGW, PGW)
● Release 9 scenarios (MBMS, Positioning)
● Release 10 enhancements in EPS (added Relays and enhanced Home eNodeB)

E-UTRA Rel. 9 Features

● Multimedia Broadcast Multicast Service (MBMS)
● MBMS architecture and PHY issues
● Self-organizing and self-optimizing networks (SON)
● SON architecture and functionalities
● LTE Positioning concept, architecture and possible location services

E-UTRA Rel. 10 PHY Enhancements

● Multicarrier transmission (OFDM/OFDMA/SCFDMA)
● Refreshment of the Rel. 8 E-UTRA (including protocol stacks, downlink and uplink radio frames, PHY channels and signals)
● Clustered SCFDMA for uplink in Rel. 10
● Bandwidth extension by carrier aggregation (use of component carriers)
● Processing of Component carriers
● Various scenarios of carrier aggregation
● RF aspects related to carrier aggregation
● Enhanced Downlink MIMO (for up to 8 antennas)
● Additional Downlink MIMO reference symbols for higher order MIMO (CSI-RS, DM-RS)
● Processing chain for DL MIMO (and comparison to Rel. 8 processing chain)
● New UL MIMO schemes (SU-MIMO for PUSCH and TX Diversity for PUCCH)
● Processing chain for UL MIMO (and comparison to Rel. 8 processing chains)
