B) When Call Re-establishment in WCDMA is activated and after RL failure or an RLC unrecoverable error, the UE goes to idle mode.
C) When Call Re-establishment in WCDMA is activated and after RL failure or an RLC unrecoverable error, the UE selects a new cell using the soft handover procedure.
D) Call Re-establishment in WCDMA targets RL failures or RLC errors in the DL.
