FRAME STRUCTURE FOR LICENSED ASSISTED ACCESS IN WIRELESS COMMUNICATION SYSTEM, METHOD AND APPARATUS USING THE FRAME STRUCTURE

摘要

Provided are a frame structure for licensed assisted access (LAA) in a wireless communication system, and a method and an apparatus using the frame structure, in which uplink resources and downlink resources can be efficiently configured even when carrier aggregation between a serving cell in a licensed band and a serving cell in an unlicensed band is configured. A communication method for a base station in a wireless communication system supporting carrier aggregation between a serving cell in a licensed band and a serving cell in an unlicensed band may comprise the steps of: determining an uplink-downlink configuration to be applied to a serving cell in an unlicensed band based on at least one of a ratio between an uplink and a downlink and the number of changes therebetween in a radio frame; transmitting information about the determined uplink-downlink configuration to a terminal; and performing uplink reception and downlink transmission based on the uplink-downlink configuration.
