HSUPA HARQ (soft combining)

It provide robustness againt occasional transmission errors. A similar scheme as for HSDPA

One main difference compared to HSDPA from the use of soft handover in uplink.
When UE is in soft handover, HARQ is terminated in multiple cells.

It is possible that few NodeB has not received data correctly and some NodeB has received correctly. So If the UE receives an ACK from at least one of the NodeBs, the UE consider the data to be successfully received.
