1. A method of performing a random access of a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), configuration information related to the random access;
identifying whether the random access is triggered to transmit a message related to a common control channel (CCCH) or to transmit a message related to a dedicated control channel (DCCH):
in case that the random access is triggered to transmit the message related to the DCCH, identifying whether a two-step random access procedure is allowed for the DCCH based on the configuration information; and
in case that the two-step random access procedure is allowed for the DCCH, performing, the two-step random access procedure.
