METHOD AND APPARATUS FOR TRANSMITTING RECEPTION ACKNOWLEDGEMENT IN WIRELESS COMMUNICATION SYSTEM

摘要

Provided are a method and apparatus for transmitting acknowledgement/not-acknowledgement (ACK/NACK) of a terminal in a carrier aggregation system, and the method comprises the following steps: setting first and second control regions as search spaces for a specific cell; detecting scheduling information with respect to the specific cell from the first control region and/or second control region; receiving a data channel from the specific cell on the basis of the scheduling information; and transmitting ACK/NACK indicating reception acknowledgement for the data channel, wherein, when the scheduling information is detected from the first control region, the ACK/NACK is transmitted using a wireless resource linked to another wireless resource through which the scheduling information is received, and when the scheduling information is detected from the second control region, the ACK/NACK is transmitted using a wireless resource preset on the basis of an upper layer signal.
