METHOD AND DEVICE FOR TRANSMITTING UPLINK ACKNOWLEDGEMENT INFORMATION IN A WIRELESS COMMUNICATION SYSTEM SUPPORTING MULTIPLE CARRIERS

摘要

The present invention relates to a wireless communication system, and more particularly, to a method and device for transmitting uplink acknowledgement information in a wireless communication system supporting multiple carriers. A method for a terminal for transmitting uplink acknowledgement information in a wireless communication system supporting multiple carriers according to one embodiment of the present invention includes: receiving downlink control information including downlink assignment index (DAI) information representing a combination of the number of downlink control channels (n total ) and a priority value (n index ); and transmitting the uplink acknowledgement information on the basis of the number of downlink control channels (n total ) and the priority value (n index ) that the DAI information represents. Here, the DAI information includes at least one DAI value, in which varying combinations of the number of downlink control channels (n total ) and the priority value (n index ) are overlapped and mapped.
