When a Universal Terrestrial Radio Access Network (UTRAN) receives an indication on Layer 3 (L3) (an L1/L2 indication is also possible) from the User Equipment (UE) that it is switching the High Speed-Data Shared Channel (HS-DSCH) reception to another cell in the active set (AS), the UTRAN sends a reconfiguration message to the UE via the target cell using a pre-configured configuration that UE has taken into use. The message can only include an indication that the pre-defined configuration can be used further by the UE or that a complete new configuration is to be used, e.g., using new HARQ info or even a hard handover (HHO) to another frequency. After receiving the configuration message, the UE responds with a normal reconfiguration complete message.
