1. A method for performing random access procedure by a user equipment in a wireless communication system, the method comprising:

  • transmitting a preamble for random access to a base station;

    receiving a random access response message through a Physical Downlink Shared CHannel (PDSCH) from the base station after the preamble is transmitted; and

    performing an operation according to only the random access response message if downlink information is received through a PDSCH at a Transmission Time Interval (TTI) or subframe during which the random access response message is received,wherein the random access response message is indicated by a Physical Downlink Control CHannel (PDCCH) masked with a Random Access-Radio Network Temporary Identity (RA-RNTI), and the downlink information is indicated by a PDCCH masked with a Cell-RNTI (C-RNTI).
