METHODS AND APPARATUS FOR REORDERING DATA IN AN EVOLVED HIGH SPEED PACKET ACCESS SYSTEM

摘要

Method and apparatus for receiving high speed downlink shared channel (HS-DSCH) transmissions are disclosed. An HS-DSCH medium access control (MAC-ehs) entity receives MAC-ehs protocol data units (PDUs) via a high speed downlink shared channel (HS-DSCH) while in one of Cell_FACH, Cell_PCH, and URA_PCH states. The reordering PDUs included in the MAC-ehs PDUs may be sent to a next processing entity without performing reordering of the PDUs. A certain reordering queue may enter a suspend state upon occurrence of a triggering event and MAC-ehs PDUs distributed to the reordering queue in the suspend state may be forwarded to the next processing entity without performing reordering. MAC-ehs reset procedure may be extended for a certain transmission such that the MAC-ehs reset is performed after receiving a MAC-ehs PDU in a target cell.

1. A method for a wireless transmit/receive unit (WTRU) to process data, the method comprising:
receiving data via a high speed downlink shared channel (HS-DSCH); and sending the data to a next processing entity without performing reordering of the reordering PDUs if a condition has been met.
