Abstract
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.

Claim
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), wherein the data comprises an HS-DSCH medium access control (MAC-ehs) protocol data unit (PDU), and wherein the MAC-ehs PDU comprises a reordering PDU; and
sending the data to a next processing entity without performing reordering of reordering PDUs if a condition has been met, wherein the sending bypasses a reordering entity, and wherein the next processing entity is a demultiplexing entity.
2. The method of claim 1, wherein the WTRU is in one of a Cell_FACH state, a Cell_PCH state, or a URA_PCH state.
3. The method of claim 1, wherein each MAC-ehs PDU is received more than once and each MAC-ehs PDU retransmission is completed before starting reception of a subsequent MAC-ehs PDU.
4. The method of claim 1, wherein the condition has been met if the data is from a certain priority queue.
5. The method of claim 1, wherein the condition has been met if the received MAC-ehs PDU is associated with a common HS-DSCH radio network temporary identity (H-RNTI).
6. The method of claim 1, wherein the condition has been met if the data is from a certain logical channel.
7. The method of claim 6, wherein the certain logical channel is one of a broadcast control channel (BCCH) or a paging control channel (PCCH).
8. The method of claim 1, wherein the received MAC-ehs PDU is received while the WTRU is in one of a Cell_FACH state, Cell_PCH state, or URA_PCH state, and further comprising setting an initial value of a next_expected_TSN to a lower edge of a receive window (RcvWindow_UpperEdge?RECEIVE_WINDOW_SIZE+1).
9. A wireless transmit/receive unit (WTRU) comprising:
a transceiver; and
a processor configured to:
receive data via a high speed downlink shared channel (HS-DSCH), wherein the data comprises an HS-DSCH medium access control (MAC-ehs) protocol data unit (PDU), and wherein the MAC-ehs PDU comprises a reordering PDU; and
send the data to a next processing entity without performing reordering of reordering PDUs if a condition has been met, wherein the sending bypasses a reordering entity, and wherein the next processing entity is a demultiplexing entity.
10. The WTRU of claim 9, wherein the WTRU is in one of a Cell_FACH state, a Cell_PCH state, or a URA_PCH state.
11. The WTRU of claim 9, wherein each MAC-ehs PDU is transmitted more than once and each MAC-ehs PDU retransmission is completed before starting transmission of a subsequent MAC-ehs PDU.
12. The WTRU of claim 9, wherein the condition has been met if the data is from a certain priority queue.
13. The WTRU of claim 9, wherein the condition has been met if the received MAC-ehs PDU is associated with a common HS-DSCH radio network temporary identity (H-RNTI).
14. The WTRU of claim 9, wherein the condition has been met if the data is from a certain logical channel.
15. The WTRU of claim 14, wherein the certain logical channel is one of a broadcast control channel (BCCH) or a paging control channel (PCCH).
16. The WTRU of claim 9, wherein the received MAC-ehs PDU is received while the (WTRU) is in one of a Cell_FACH state, Cell_PCH state, or URA_PCH state, and further comprising setting an initial value of a next_expected_TSN to a lower edge of a receive window (RcvWindow_UpperEdge?RECEIVE_WINDOW_SIZE+1).
