In Soft Handover

1
In soft handover, UE will make multiple radio links with cells in active set. In R99 case, UE will send and receive data on all radio links. UE will send and receive signaling over SRB with all cells. RNC will send same data to UE from all active cells ad UE will combine data from all cells using max ratio combination. Therefore, In DT we observe only one message on DL of every kind such as measurement control message which contain either combination of neighbors of all cells or neighbor of only best cell depending on switch setting.

In soft handover, UE will make multiple radio links with cells in active set. In R99 case, UE will send and receive data on all radio links. UE will send and receive signaling over SRB with all cells. RN will send same data to UE from all active cells ad UE will com!ine data from all cells using ma" ratio com!ination.#herefore, In $# we o!serve onl% one message on $& of ever% kind such as measurement control message which contain either com!ination of neigh!ors of all cells or neigh!or of onl% !est cell depending on switch setting.
