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.

Abstract: The present invention relates to a method of avoiding collision in a. More specifically, the present invention relates to a method of effectively avoiding collision when resources are allocated to and used by substantial mobile terminals in a synchronous wireless distribution communication system. The method of avoiding collision includes: determining, by a terminal, a slot to be transmitted in a main frequency channel; in a slot prior to the determined slot, performing contention using a contention deputy channel having a different frequency from the main frequency channel; and using the selected slot of the main frequency channel when winning the contention.
