TERMINAL, METHOD WHEREBY TERMINAL TRANSMITS RESPONSE INFORMATION ON DOWNLINK DATA, BASE STATION, AND METHOD WHEREBY BASE STATION INDICATES TRANSMISSION OF RESPONSE INFORMATION ON DOWNLINK DATA

摘要

The method whereby a terminal, which communicates with a base station by using a plurality of serving cells, transmits response information on downlink data according to one embodiment of the present invention comprises the steps of: receiving control information via a physical downlink control channel (PDCCH) or an enhanced PDCCH (EPDCCH) in at least one downlink serving cell among the plurality of serving cells and receiving downlink data via a physical downlink shared channel (PDSCH); determining an uplink serving cell, which is to transmit response information on the downlink data, on the basis of the control information; and transmitting the response information on the downlink data via the determined uplink serving cell.
