LTE Small cell deployed with zero-touch

− Small cell discovers SC GW and establishes connectivity

− Small cell auto-sets radio parameters such as PCI and frequency

− Small cell identifies 3G macro for CSFB

Handovers both directions between macro and small cell

− No manual configuration on macro cell or small cell

− Macro-cell initiated handovers based on system-information

reading with gaps

− Handover in presence of confusion helps high density small cells!

− Small-cell initiated handovers based on Network Listen, UE ANR

and UE measurements
