<P>PROBLEM TO BE SOLVED: To provide a method and communication apparatus for handling a contention-based random access procedure in UE (user equipment) of a wireless communication system, so as to appropriately terminate retransmission of a scheduled transmission message for preventing uplink transmission of other UE from being interfered. Ž<P>SOLUTION: The method includes the steps of: sending a scheduled transmission message, which applies an HARQ (hybrid automatic repeat request) process for transmission; starting a contention resolution timer and monitoring a PDCCH (physical downlink control channel); and eliminating the content of a buffer of the HARQ process when a contention result of the contention-based random access procedure is determined, to terminate the retransmission of the scheduled transmission message.
