Abstract  Abstract

A method and apparatus for cell update while in a Cell_FACH state is disclosed. After selecting the target cell, system information including the high speed downlink shared channel (HS-DSCH) common system information is read from the target cell. The radio network temporary identity (RNTI) received at the source cell is cleared and the variable HS_DSCH_RECEPTION is set to TRUE. The HS-DSCH Media Access Control (MAC-hs) entity is configured based on the HS-DSCH common system information. High speed downlink packet access (HSDPA) transmissions are then received at the target cell. A CELL UPDATE message is sent to notify of cell changes. HSDPA transmission may be received using a common H-RNTI broadcast in system information, a H-RNTI retained when requested in a CELL UPDATE message, or a temporary identity that is a subset of the U-RNTI. The MAC-hs entity may be reset.
