HANDLING CELL RESELECTIONS AND STATE TRANSITIONS FOR HIGH-SPEED DOWNLINK PACKET ACCESS

摘要

A WIRELESS TRANSMIT RECEIVE UNIT (WTRU) (110) IS CONFIGURED TO OPERATE IN AN HIGH SPEED DATA PACKET ACCESS (HSDPA) MODE IN A CELL AND/OR STATE AND TO CLEAR HSDPA RESOURCES WHEN MOVING OUT OF THE CELL AND/OR STATE. THE WTRU (110) IS CONFIGURED TO CLEAR HSDPA RESOURCES WHEN CONDITIONS TO PERFORM HIGH SPEED DOWNLINK SHARED CHANNEL RECEPTION ARE NOT MET. IN PARTICULAR, A NEW VARIABLE CALLED HS_DSCH_RESEPTION_GENERAL IS SET TO FALSE IF A NEW CELL FOLLOWING A CELL RESELECTION OR A NEW STATE FOLLOWING A STATE TRANSITION DOES NOT SUPPORT HS_DSCH_ RECEPTION. STOP HS_SCCH RECEPTION. STOP HS-DSCH RECEPTION. CLEAR RNTI. RESET MAC_HS. RELEASE HARQ RESOURSCES. SET HS_DSCH_RESEPTION_GENERAL TO TRUE IF HS_DSCH IS ONGOING. CELL_FACH, CELL_PCH, URA_PCH AND CELL_DCH.
