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).

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: 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 an d 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 unassigne d positions (106); and marking as assigned all child nodes of the assigned position node in the layer corresponding to the repetition period (107).

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) (12) and a Node B (54). The system monitors certain criteria and, if necessary, adaptively increases or decreases the data flow between the RNC (12) and the Node B (54). 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 (54). Flow control is exerted to reduce buffering in the Node B (54) upon degradation of channel qualities, and prior to a High Speed Downlink Shared Channel (HS-DSCH) handover.

Abstract: A SYSTEM AND METHOD 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 , WHICH PROMPTS THE NODE B TO DELETE AT LEAST A PORTION OF BUFFERED DATA. THE PURGE COMMAND 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.

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.
