1. A method for performing a random access in a terminal of a wireless communication system, the method comprising:
transmitting a random access preamble to a base station;
receiving a first signal through a first channel from the base station;
determining that an identifier is used in the first signal;
after determining that the identifier is used in the first signal, obtaining a first message from the first signal; and
receiving a second message through a second channel based on the first signal,
wherein the second message comprises a first random access response for the terminal and information which indicates that the second message comprises a second random access response,
wherein the information consists of a single bit, and
wherein a first value of the single bit indicates that the second message comprises the second random access response.
