Abstract: Un método para detectar y corregir errores de transmisión en un sistema de comunicaciones inalámbricas (600), en que el método comprende: (a) recibir una pluralidad de bloques de datos por medio de una primera transmisión (620), incluyendo cada bloque de datos un único número de secuencia de transmisión (TSN); (b) determinar que un bloque de datos que tenga una TSN esperada no ha sido recibido por medio de una primera transmisión (620); caracterizado por (c) generar un mensaje de informe de estado de TSN (625) que identifica una TSN que falte, correspondiente al bloque de datos que no fue recibido por medio de la primera transmisión (620), incluyendo el mensaje de informe de estado de TSN (625) un primer conjunto de bits usado para identificar la TSN que falta, y un segundo conjunto de bits usado para identificar una cola de reordenación particular (610), ala cual esté destinada la TSN que falta: (d) retransmitir un bloque de datos que incluye la TSN que falta, por medio de una segunda transmisión (630) en respuesta al mensaje de informe de estado de TSN (625); y (e) colocar el bloque de datos retransmitido en un lugar específico en la cola de reordenación particular (610), designado por el segundo conjunto de bits del mensaje de informe de estado de TSN (625),

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 th e status PDU is coupled with the MAC layer reset. The RNC generates a message with a MAC reset indication (16). Following the MAC layer reset all PDUs stored in the UE MAC layer reordering buffers (22) are flushed to RLC entiti es (24) and then processed by RLC entities prior to the generation of a PDU status report (26). 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 (28), missing PDUs are realized and retransmitted to the UE (30).

More particularly, memory will be shared among the MAC reordering buffers and the RLC reception buffers.

Abstract: A METHOD FOR MULTIPLEXED SCHEDULING OF INFORMATION BLOCKS FROM MULTIPLE SOURCES ON A SINGLE COMMUNICATION CHANNEL DIVIDED INTO MULTIPLE ADDRESS POSITIONS (150). THE INFORMATION BLOCK FROM EACH SOURCE HAS A REPETITION PERIOD AND IS DIVIDED INTO A NUMBER OF SEGMENTS. THE METHOD INCLUDES DETERMINING THE TOTAL NUMBER OF POSITIONS ON THE CHANNEL TO BE SCHEDULED (101); MAPPING POSITIONS IN A NON-SEQUENTIAL ORDER CORRESPONDING TO NODES IN ABINARY TREE (103), WHEREBY EACH LAYER OF THE BINARY TREE CORRESPONDS TO A REPETITION PERIOD; ORDERING THE BLOCKS BY REPETITION PERIOD (106), STARTING WITH THE SMALLEST REPETITION PERIOD; ASSIGNING INFORMATION SEGMENTS OF EACH BLOCK TO UNASSIGNED POSITIONS; AND MARKING (107) AS ASSIGNED ALL CHILD NODES OF THE ASSIGNED POSITIONS NODE IN THE LAYER CORRESPONDING TO THE REPETITION PERIOD .

Abstract: A method for receiving a segmented communication begins by periodically transmitting the segmented communication. The segmented communication is received and each segment of the segmented communication is examined to determine if the segment is valid. If the segment is valid, then the segment is stored. If the segment is invalid, then the invalid segment is identified. The segmented communication is retransmitted and received. Only the identified invalid segments of the retransmitted communication are examined to determine if the previously invalid segments are now valid.

Abstract: Un sistema y método que mejoran la performance de un sistema de transmisión inalámbrica mediante el uso inteligente del control del flujo de datos entre un controlador de red de radio (RNC) y un Nodo B. El sistema monitorea determinados criterios y, de ser necesario, aumenta o reduce en forma adaptativa, el flujo de datos entre el RNC y el Nodo B. Esto mejora la performance del sistema de transmisión permitiendo que los datos re-transmitidos, los procedimientos de senalización y otros datos, sean recibidos exitosamente a una velocidad mayor, minimizando la cantidad de datos bufferizados en el Nodo B. El control de flujo es realizado para reducir la bufferización en el Nodo B ante la degradación de calidades de canal, y con anterioridad a una transferencia de Canal Compartido de Enlace Descendente de Alta Velocidad (HS-DSCH).

Abstract: A system and method which improve the performance of a wireless transmission system by intelligent use of the control of the flow of data between a radio network controller (RNC) and a Node B. The system monitors certain criteria and, if necessary, adaptively increases or decreases the data flow between the RNC and the Node B. This improves the performance of the transmission system by allowing retransmitted data, signaling procedures and other data to be successfully received at a faster rate, by minimizing the amount of data buffered in the Node B. Flow control is exerted to reduce buffering in the Node B upon degradation of channel qualities, and prior to a High Speed Downlink Shared Channel (HS-DSCH) handover.

Abstract: The present invention relates to efficient recovery of High Speed Downlink Packet Access (HSDPA) data following handover. The present invention discloses a method and system for the UE to perform a serial of actions in order to reduce the latency and potentially prevent loss 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 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 signaled 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.
