A method of efficiently processing a random access response message, when a terminal (or user equipment) performs random access, is disclosed. After the terminal transmits a random access preamble to a base station, the terminal may receive a random access response message having a format of medium access control protocol data unit (MAC PDU) including only a backoff indicator subheader in a MAC header of the MAC PDU, from the base station in response to the random access preamble. As described above, the terminal, which has received the random access response message including only a backoff indicator subheader in the MAC header of the MAC PDU, may consider a random access response reception procedure not successful and may perform a subsequent procedure for a random access responses reception failure.
