1. A method of transmitting uplink data in a wireless communication system, the method comprising:

  • receiving in a terminal from a network, preamble information generated by the network, wherein the preamble information is received via dedicated signaling in downlink,wherein the received preamble information is either a dedicated preamble or an index of the dedicated preamble, and wherein the preamble information is used for performing a random access channel (RACH) procedure, andwherein the dedicated preamble is used for a specific terminal;

    transmitting from the terminal to the network, the dedicated preamble on a random access channel (RACH) in uplink;

    uplinkreceiving in the terminal, a random access response in response to the transmitted dedicated preamble, wherein the random access response includes at least one of time information for a handover operation, an uplink grant for the handover operation, time information for a downlink data arrival, or a random access preamble identifier; and

    transmitting the uplink data to the network using the uplink grant included in the random access response.
