LTE Advanced and the Radio Interface

Course Description

LTE Advanced introduces features in the network such as Carrier Aggregation, Self Optimized Networks (SON), Coordinated Multi Point (COMP), Heterogenous Network, enhanced Inter Cell Interference Coordination, eICIC, Enhanced MIMO Support and Relay Architecture.

The course "LTE Advanced and the Radio Interface" combines a thorough analyzis of the E-UTRA (LTE Radio Interface) with a careful description of all the new features of LTE Advanced.

One of the most important parts of the LTE is the E-UTRAN protocol Architecture which is analyzed in-depth as is also the Layer 1 information Processing.

The new modulation schemes and methods are discussed by studying OFDM and MIMO in E-UTRA. The Synchronization & Network Access and the Downlink and Uplink Transmission Procedures are also described
