METHOD AND APPARATUS FOR REORDERING UPLINK DATA PACKETS USING TRANSMISSION SEQUENCE NUMBERS AND TIME STAMPS IN A MOBILE COMMUNICATION SYSTEM

摘要

ABSTRACT OF THE DISCLOSURE A method and apparatus for reordering data sent from a user equipment (UE). The UE assigns transmission sequence numbers (TSNs) to medium access control (MAC)-e protocol data units (PDUs) through an enhanced uplink dedicated channel (E-DCH). A Node B assigns, to received PDUs, time stamps (TSs) indicating time points when the PDUs are received. Using the TSNs and the TSs, a radio network controller (RNC) solves a problem of PDU disorder due to hybrid automatic retransmission request (HARQ) operations and transfer delay between the Node B and the RNC, and reorders the PDUs.
