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: determining indexes relative to a plurality of downlink component carriers and a plurality of uplink component carriers; receiving, from a base station, DCI 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 DCI, wherein the DCI includes an index that indicates the uplink component carrier which transmits the uplink signal among the plurality of uplink component carriers.
