Tell Me How Does Soft/softer Handover Work? |
|
Answer» ★ Soft/softer handover down-link: UE rake receiver performs maximum ratio combining, i.e. UE COMBINES multi-path signals and FORM a stronger SIGNAL. ★ Soft handover up-link: RNC performs selection combining, i.e. RNC SELECTS the better signal coming from multiple NodeB. ★ Softer handover up-link: NodeB performs maximum ratio combining, i.e. NodeB rake receiver combines signals from different paths and forms a stronger signal ★ Soft/softer handover down-link: UE rake receiver performs maximum ratio combining, i.e. UE combines multi-path signals and form a stronger signal. ★ Soft handover up-link: RNC performs selection combining, i.e. RNC selects the better signal coming from multiple NodeB. ★ Softer handover up-link: NodeB performs maximum ratio combining, i.e. NodeB rake receiver combines signals from different paths and forms a stronger signal |
