Abstract

A scan reporting method for an inactive secondary carrier in a wireless access system includes receiving, from a base station, a multicarrier advertisement (MC-ADV) message including reference carrier information, the reference carrier information indicating a carrier index of a reference carrier representing a carrier group, performing scanning of an assigned secondary carrier including at least one of an active secondary carrier and an inactive secondary carrier, and reporting, to the base station, the scan result of the inactive secondary carrier, wherein the scan result of a carrier corresponding to the lowest carrier index, of assigned secondary carriers linked to the reference carrier is reported to the base station.
