Title:
COMMUNICATION METHOD IN MOBILE COMMUNICATION SYSTEM USING UNLICENSED FREQUENCY BAND, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/072816
Kind Code:
A3
Abstract:
The present disclosures provides a method in a communication system for scheduling, by a base station, a terminal which uses an unlicensed band channel, comprising: a step in which a base station transmits scheduling information with respect to an unlicensed band to a terminal through a licensed band channel in a first subframe; a step in which the base station performs a search for the unlicensed band channel; and a step in which, if the search for the unlicensed band channel is successful, downlink data is transmitted to the terminal through the unlicensed band channel on the basis of the scheduling information.
