LTE Rel 10 Features and Beyond

Subject: LTE-A and 5G
Category: Emerging Techniques
Duration: 1 day

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

Fundamentals of E-UTRA Rel. 10 PHY Enhancements

● Clustered SCFDMA for uplink in Rel. 10
● Bandwidth extension by carrier aggregation (use of component carriers)
● Processing of Component carriers
● Enhanced Downlink MIMO (for up to 8 antennas)
● Additional Downlink MIMO reference symbols for higher order MIMO (CSI-RS, DM-RS)
● New UL MIMO schemes (SU-MIMO for PUSCH and TX Diversity for PUCCH)

E-UTRA Rel. 10 Protocols and Procedures

● Protocol stack for Carrier Aggregation
● CA procedures (addition and release, activation and deactivation of component carrier)
● Primary and Secondary Component Carriers for Downlink OFDMA and Uplink SCFDMA
● Idle and Connected mode issues (System info acquisition and RRC signaling for CA usage, RRC idle-to-connected state change and HO timing requirements)
● CA challenges (scheduling and Handover aspects)
● MAC issues with relation to CA: user data allocation and signaling aspects (including cross carrier scheduling)
● Additional L1 signaling formats (PUCCH format 3 and DCI format 4)

E-UTRA Release 11 and Beyond Features

● Cooperative Multipoint Transmission/Reception
● CoMP downlink and uplink scenarios
● Mobile Type Communications (MTC) concept and possible services
● Mobile Relays concept
