摘要： A system (Fig. 4) and method (50) which permit the RNC to control purging of data buffered in the Node B. The RNC monitors for a triggering event, which initiates the purging process. The RNC then informs the Node B of the need to purge data by transmitting a purge command (54), which prompts the Node B to delete at least a portion of buffered data. The purge command (54) can include instructions for the Node B to purge all data for a particular UE, data in one or several user priority transmission queues or in one or more logical channels in the Node B, depending upon the particular data purge triggering event realized in the RNC.

摘要： 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.

摘要： A method for multiplexed scheduling of information blocks from multiple sources on a single communication channel divided into multiple address positions. 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 coresponding to nodes in a binary tree (103); whereby each layer of the binary tree corresponds to a repetition period; ordering the blocks by repetition period, starting with the smallest repetition period; assigning information segments of each block to unassigned positions (106); and marking as assigned all child nodes of the assigned position node in the layer corresponding to the repetition period (107).

摘要： 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 (14). PDU status may be signaled for each radio link controller 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).

摘要： A wireless communication system is configured to monitor transmission sequence numbers (TSNs) assigned to protocol data units (PDUs) processed by the system. The system includes at least one user equipment (UE) (605) having, a queue, and a Node B (615) in communication with the UE. The UE determines that a data block having an expected TSN was not received, and generates a TSN status report message (625). The Node B retransmits a data block (630) including the expected TSN to the UE in response to the TSN status report message. The retransmitted data block is placed in a specific location in the queue designated by the TSN status report message.

摘要： A wireless communication method system for detecting and correcting transmission errors. The system includes at least one Wireless Transmit/Receive Unit (WTRU) in communication with a Node B. At step 405 the Node B sends a transmission signal (including a protocol data unit (PDU)) to the WTRU. The WTRU generates a Revert Message having a first field and a second field to indicate whether the transmission signal was successfully received at the WTRU. The WTRU transmits the Revert Message to the Node B. The Node B receives the first field (step 410) and the second field (step 420) and determines the contents (steps 415 and 425). The Node B compares the contents of the first field to the contents of the second field (step 430). The Node B resends the transmission signal to the WTRU if the contents of the first and second fields are not logically consistent (step 450).
