Abstract:
Provided are a method for operating a terminal in a carrier aggregation system and an apparatus using said method. Downlink control information (DCI) including a downlink assignment index (DAI) is received via an enhanced physical downlink control channel (E-PDCCH). The DCI received via the E-PDCCH includes an additional field which does not exist in the DCI received via a physical downlink control channel (PDCCH). If the DAI value is larger than 1, the additional field is used in selecting one of a plurality of PUCCH resources set by the upper layer, and the one resource is used in transmitting ACK/NACK.
