Abstract: A method for transmitting uplink control information at a communication apparatus in a time division duplex (TDD) wireless communication system. The method according to one embodiment includes receiving at least one physical downlink control channel (PDCCH) or at least one physical downlink shared channel (PDSCH); and generating reception response information for the at least one PDCCH or the at least one PDSCH. When the reception response information and channel status information are configured to be transmitted in a same subframe, if a certain condition is satisfied, the reception response information and the channel status information are transmitted together using a first physical uplink control channel (PUCCH) format. The certain condition includes a first condition of a single PDCCH transmission only on a primary cell (PCell) that has a downlink assignment index (DAI) initial value and indicates a semi-persistent scheduling (SPS) release being present.

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.
