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).

Abstract
A method for processing data in a wireless communication system is provided. The method includes receiving a first uplink scheduling command indicating a first radio resource, receiving a second uplink scheduling command indicating a second radio resource through a random access response, and stopping a procedure associated with the second uplink scheduling command when the first radio resource and the second radio resource collide.

7. An user equipment in a wireless communication system, the user equipment comprising:
-
a radio frequency (RF) module configured to transmit/receive a radio signal to/from a base station; a symbol generation module connected to the RF module and configured to generate Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbol to be transmitted to the base station; and a processor configured to control the RF module and the symbol generation module and to perform operations according to radio interface protocol, wherein the processor is configured to transmit a preamble for random access to the base station; receive a random access response message through a Physical Downlink Shared CHannel (PDSCH) from the base station after the preamble is transmitted; and perform 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). - View Dependent Claims (8, 9, 10, 11)
