Abstract: The present invention relates to a method for receiving a downlink control signal in a TDD-based wireless communication system, and to an apparatus therefor. The method comprises receiving a downlink signal via a downlink interval in a specific frame including the downlink interval, a guard interval and an uplink interval. A combination of the downlink interval, the guard interval and the uplink interval is given using configuration information on the specific subframe. When the configuration information is given such that the length of the downlink interval is larger than a specific value, detecting a first type of PDCCH is performed in the specific subframe. When the configuration information is given such that the length of the downlink interval is equal to or smaller than the specific value, detecting the first type of PDCCH is skipped in the specific subframe.

Abstract: 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.
