According to this disclosure, a method by which a terminal performs LBT in a wireless access system supporting an unlicensed band and multiple carriers can comprise receiving, from a base station, each of uplink grants for scheduling uplink channels on two or more component carriers (CCs); randomly selecting a first CC on which a first LBT is to be performed from among the two or more CCs; performing the first LBT on the selected first CC; and performing a second LBT on the remaining CCs among the two or more CCs, wherein the first LBT can be a random back-off-based LBT for performing a random back-off by a random back-off counter value, and the second LBT can be a channel sensing-based LBT for sensing a channel during a predetermined time interval before uplink transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for performing LBT process on multiple carriers in wireless access system supporting unlicensed band","description":"The present invention relates to a wireless access system supporting an unlicensed band.
