摘要：
A method and corresponding apparatus, where the apparatus transmits, to a user equipment (UE), downlink control information (DCI) including a downlink assignment index (DAI) through an enhanced physical downlink control channel (E-PDCCH). The DCI transmitted through the E-PDCCH includes an additional field which is not present in DCI transmitted through a physical downlink control channel (PDCCH). If the DAI value included in the DCI is greater than 1, the additional field is used to determine a single resource for the ACK/NACK among the plurality of PUCCH resources configured by a higher layer signal.
