Duration: 1 day

Course outline:

LTE, SON and HetNets Introduction

● Features of LTE Releases and main radio parameters
● LTE / LTE-Advanced network architecture (UE, eNB, HeNB, RN, MME, S-GW, P-GW, HSS, etc.)
● Heterogeneous Networks (HetNets) in the context of SON
● SON concept and background (SON drivers, expected benefits and challenges)
● SON areas (self-configuration, self-optimization and self-healing)


● Importance of Multi-RAT SON approach
● Cross technology SON (including high level architecture)
● Example algorithms: Multi-RAT ES and MLB
● Example antenna based SON architecture for Multi-RAT base station

E-UTRA Rel. 10 Home eNBs, HetNets and SON

● LTE HeNB architecture possibilities (HeNB, HeNB GW and SeGW)
● Access control and CSG management (types of cells: open, hybrid and closed)
● Heterogeneous Network (HetNet) concept (Macro, Pico, Femto cells and relays)
● Interference scenarios
● LTE inter cell interference coordination (ICIC) in time and frequency

LTE Advanced and HetNet Deployment

● Backward compatibility to LTE Rel. 8 requirements
● Transparency of Relay nodes (and RNs deployment issues)
● Migration from LTE Rel. 8 to LTE Advanced Rel. 10
● HetNet deployment
