    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 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.

    Abstract: RADIO RESOURCE CONTROL-SERVICE DATA UNIT RECEPTION A method for processing a received communication (80) which includes periodic transmissions of a set of information segments. A first transmission of the set of information segments is received and processed to identify each of the 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), subsequent transmissions (85) of the set of information segment 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 all segments of the set have been stored.
