Abstract: Provided is an access method using carrier sensing in a communication system. A random access method according to an embodiment of the present invention includes performing sensing with respect to a carrier in a first part of a radio slot, and transmitting preemptive occupation signals for the carrier through the carrier in a second part after the first part of the radio slot when the carrier is in a non-occupied state based on the sensing result in the first part. Accordingly, in the random access method according to the present invention, efficient random access may be made possible even when there are access requests from a large number of terminals in a narrow frequency band in a communication system.
