Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and apparatus for performing cell update (and cell reselection) while in a Cell_FACH state.

SOLUTION: After selecting a target cell system information is read from the target cell including high speed downlink shared channel (HS-DSCH) common system information. A radio network temporary identity (RNTI) received in a source cell is cleared and a variable HS_DSCH_RECEPTION is set to TRUE. An HS-DSCH medium access control (MAC-hs) entity is configured based on the HS-DSCH common system information. A CELL UPDATE message is sent to notify of a cell change. High speed downlink packet access (HSDPA) transmission may be received using a common H-RNTI broadcast in the system information a reserved H-RNTI as requested in the CELL UPDATE message or a temporary identity which is a subset of a U-RNTI. The MAC-hs entity may be reset.
