Abstract: THE PRESENT INVENTION RELATES TO EFFICIENT RECOVERY OF HIGH SPEED DOWNLINK PACKET ACCESS (HSDPA) DATA FOLLOWING HANDOVER. THE PRESENT INVENTION DISCLOSES A METHOD (10) AND SYSTEM FOR THE UE TO PERFORM A SERIAL OF ACTIONS IN ORDER TO REDUCE THE LATENCY AND POTENTIALLY PREVENT LOSE OF PDU TRANSMISSION DURING THE SERVING HS-DSCH CELL CHANGE PROCEDURE. A NEW CRITERION IS INTRODUCED FOR UE GENERATION OF THE STATUS REPORT OF RLC PDU. THE UE GENERATES STATUS REPORT OF THE STATUS OF RLC PDU. THE UE GENERATES STATUS REPORT (STEP 20) OF THE PDUS AS SOON AS POSSIBLE FOLLOWING NOTIFICATION OF THE HS-DSCH CELL CHANGE INDICATED BY THE RRC PROCEDURE TO MORE EFFICIENTLY RECOVER SOURCE NODE B BUFFERED DATA. PDU STATUS MAY BE SIGNALLED FOR EACH AM RLC INSTANCE ASSOCIATED WITH THE HS-DSCH TRANSPORT CHANNEL. 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.FIG. 1

Abstract: The invention provides the (UE) and (RNC) reduce of transmission latency and potentially prevent loss of (PDU)s upon a MAC layer reset. UE generation of the status PDU is coupled with the MAC layer reset. The RNC generates a 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 realized and retransmitted to the UE.

Abstract: Un método de un Nodo B (104) para transferir datos en un sistema de comunicación inalámbrica, incluyendo el Nodo B una pluralidad de memorias intermedias de transmisión que tienen prioridades respectivas, comprendiendo el método los pasos de: recibir una pluralidad de bloques de datos; almacenar cada bloque de datos recibido en una memoria intermedia de transmisión que tiene una prioridad correspondiente a la prioridad del bloque de datos; transmitir los bloques de datos almacenados en las memorias intermedias de transmisión; recibir bloques (114) de datos marcados, en los que cada bloque de datos marcado es un bloque de datos que ha sido marcado después de una determinación de que no fue recibido satisfactoriamente por un equipo de usuario y necesita ser retransmitido; incrementar (116) la prioridad de cada bloque de datos marcado recibido; almacenar (116) cada bloque de datos marcado recibido en una memoria intermedia de transmisión que tiene una prioridad correspondiente a la prioridad incrementada del bloque de datos marcado; y transmitir (118) los bloques de datos almacenados en las memorias intermedias de transmisión, en los que los bloques de datos de una memoria intermedia de prioridad más alta son transmitidos antes de que los bloques de datos de una memoria intermedia de prioridad más baja.

Abstract: A system and method in accordance with the present invention reduce the amount of data that is stalled in a source Node B after a serving HS-DSCH cell change in a communication system that includes a serving RNC and at least one Node B. In a first embodiment, the RNC temporarily suspends data transmissions from the RNC to the Node B. In a second embodiment, the activation time is used in data scheduling. In a third embodiment, a more robust MCS level is selected. In a fourth embodiment flow control is employed for the data transmitted between the RNC and the Node B.

Abstract: The present invention is a method and system for the User Equipment to perform a series of actions in order to reduce the latency and potentially to prevent 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. PDU status may be signaled for each radio link controller associated with the HS-DSCH transport channel. 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.

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.
