SIGNAL TRANSMISSION AND RECEPTION METHOD IN WIRELESS COMMUNICATION SYSTEM SUPPORTING CARRIER AGGREGATION, AND DEVICE FOR SAME

摘要

The present invention relates to a signal transmission and reception method and device using a plurality of cells of a terminal in a wireless communication system supporting a carrier aggregation. Particularly, the signal transmission and reception method comprises the steps of: receiving transmission control information for a primary cell (PCell) and a secondary cell (SCell) according to uplink-downlink configurations different from each other; transmitting and receiving a signal in a specific time period according to the transmission control information; and performing a signal transmission and reception operation according to a pre-defined configuration when a signal transmission in a specific time period is not indicated in the transmission control information.
