COMMUNICATION METHOD OF TERMINAL IN CARRIER AGGREGATION SYSTEM, AND TERMINAL

摘要

The present invention provides a communication method of a terminal in a carrier aggregation system. The method comprises the steps of: determining indexes relative to a plurality of downlink component carriers and a plurality of uplink component carriers; receiving, from a base station, downlink control information through at least one downlink component carrier among the plurality of downlink component carriers; and transmitting an uplink signal to the base station through an uplink component carrier determined on the basis of the downlink control information, wherein the downlink control information includes an index that indicates the uplink component carrier which transmits the uplink signal among the plurality of uplink component carriers.
