Abstract

A method and apparatus for serving high speed downlink shared channel (HS-DSCH) cell change is disclosed. A wireless transmission / reception unit (WTRU) sends a measurement report to transmission power control (TPC) when the signal strength of the target cell approaches the signal strength of the source cell. The RNC adds the target cell to the active set and sends preloaded pre-HS-DSCH configuration information for the target cell to the WTRU. The WTRU sends another measurement report when the signal strength of the target cell exceeds the signal strength of the source cell. The WTRU monitors the high-speed shared control channel (HS-SCCH) on the target cell based on the pre-loaded HS-DSCH configuration information and decodes the HS-SCCH transmission. The WTRU determines whether a MAC-hs / ehs reset is necessary and resets the MAC-hs / ehs entity before receiving an HS-DSCH transmission from the target cell if necessary.
