Abstract: A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC layer reset. UE generation of the status PDU is coupled with the MAC layer reset. The RNC generates a 5 message with a MAC reset indication. Following the MAC layer reset all PDUs stored in the UE MAC layer reordering buffers are flushed to RLC entities and then processed by RLC entities prior to the generation of a PDU status report. The PDU status report provides to the RNC the status of all successfully received PDUs. Upon reception of a PDU status report in the RNC missing PDUs are 10 realized and retransmitted to the UE. 12 RECOGNIZE THE NEED TO RESET MAC LAYER INFORM NODE B OF SERVING 14~ HS-DSCH CELL CHANGE 18 _ -- ___I_ UE RRC RECEIVES AND CHECKS RRC MESSAGE INFORM UE OF MAC LAYER WHETHER A MAC LAYER MAC LAYER RESET RESET INDICATOR IS SET RESET INDICATOR , 16 UERRC INFORMS THE MAC 20 LAYER TO RESET MAC LAYER RESETS AND 22 FLUSHES REORDERING BUFFERS RLC INSTANCES PROCESS -24 FLUSHED DATA 28 RLC GENERATES AND SENDS PDU STATUS PDU STATUS REPORT STATUS REPORT OF PDUs PROCESSED 26 MISSING PDUS TRANSMITTED 30 TO THE UE

Abstract: The present invention is a method and system for the User Equipment to perfo rm a series of actions in order to reduce the latency and potentially to preven t loss of packet data unit transmission during the serving HS-DSCH cell change procedure. A new criterion is introduced for the UE generating status report of the PDUs as soon as possible following notification of the cell change indicated by the RRC procedure to more efficiently recover source NODE B buffered data (14). PDU status may be signaled for each radio link controlle r associated with the HS-DSCH transport channel (20). Furthermore, upon Inter Node B serving HS-DSCH cell change the SRNC may wait for PDU status report before initiating transmission of new data in target cell (26).

Abstract: The present invention allows for effective sharing of the hardware memory of a wireless transmit receive unit (WTRU). The memory will be shared among various buffers of different entities. More particularly, memory will be shared among the MAC reordering buffers and the RLC reception buffers.

Abstract: A method for processing a received communication (80) which includes periodi c transmissions of a set of information segments. A first transmission of the set of information segments is received and processed to identify each of th e segments as valid or invalid (81). The valid segments (82) of the first set are then stored. Where all segments of the set are not stored (83), subseque nt transmissions (85) of the set of information segments are received and only those segments not previously stored are processed to identify each such segment as valid or invalid. The valid segments so identified (81) are then stored (82). Subsequent transmissions (85) are repeatedly received unless al l segments of the set have been stored.

Abstract: A system and method are disclosed for managing packet data units (PDUs) received by a Node B from a radio network controller (RNC) and stored in a buffer of the Node B while awaiting transmission to a user equipment (UE). A purge triggering event with respect to PDUs associated with the UE is detected at the RNC and the RNC transmits a purge message to the Node B requesting a purge of at least a portion of the PDUs associated with the UE from the Node B's buffer. The requested PDUs are then deleted from the Node B's buffer.

Abstract: A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC-hs layer reset. The RNC generates a radio resource control (RRC) message with a MAC-hs reset indication. The MAC reset indication requires the UE to flush buffers for configured HARQ processes, disassemble MAC protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data.
