How Does Soft/softer Handover Work?

1.	How Does Soft/softer Handover Work?
Answer» Soft/softer HANDOVER downlink: UE rake receiver PERFORMS maximum ratio combining, i.e. UE combines multi-path signals and form a stronger signal. Soft handover UPLINK: RNC performs selection combining, i.e. RNC selects the better signal coming from multiple NodeB. Softer handover uplink: NodeB performs maximum ratio combining, i.e. NodeB rake receiver combines signals from different PATHS and forms a stronger signal. Soft/softer handover downlink: UE rake receiver performs maximum ratio combining, i.e. UE combines multi-path signals and form a stronger signal.

Soft/softer HANDOVER downlink: UE rake receiver PERFORMS maximum ratio combining, i.e. UE combines multi-path signals and form a stronger signal.

Soft handover UPLINK: RNC performs selection combining, i.e. RNC selects the better signal coming from multiple NodeB.
Softer handover uplink: NodeB performs maximum ratio combining, i.e. NodeB rake receiver combines signals from different PATHS and forms a stronger signal.

Soft/softer handover downlink: UE rake receiver performs maximum ratio combining, i.e. UE combines multi-path signals and form a stronger signal.
