METHOD AND DEVICE OF TRANSMITTING A PLURALITY OF RECEPTION CONFIRMATION INFORMATION

摘要

The present invention relates to a method and device of transmitting acknowledgement/not-acknowledgement (ACK/NACK) of a terminal set having a plurality of serving cells in a wireless communication system. The method includes: receiving a first physical downlink control channel (PDCCH) and a second PDCCH through at least one serving cell among the plurality of serving cells; receiving a first physical downlink shared channel (PDSCH) scheduled by the first PDCCH; receiving a second PDSCH scheduled by the second PDCCH; allocating a first physical uplink control channel (PUCCH) resource on the basis of the lowest index of a control channel element (CCE) through which the first PDCCH is transmitted; allocating a second PUCCH resource on the basis of the lowest index of the CCE through which the second PDCCH is transmitted; and transmitting ACK/NACK on the first PDSCH and the second PDSCH through a serving cell linked with a serving cell receiving the first PDCCH and the second PDCCH. A transmission resource transmitting the ACK/NACK is selected from the first PUCCH resource and the second PUCCH resource.
