    摘要: Provided are a method and apparatus for transmitting positive-acknowledgement (ACK)/negative-acknowledgement (NACK) in a time division duplex (TDD)-based wireless communication system. A user equipment receives an uplink grant which includes an uplink resource assignment and an uplink downlink assignment index (DAI), determines an ACK/NACK payload size on the basis of a value of the uplink DAI, and generates an ACK/NACK response for the at least one downlink transport block. The user equipment multiplexes the ACK/NACK response on an uplink transport block, and transmits the multiplexed ACK/NACK response.

    摘要: Provided are a method and a device for ACK/NACK transmission in a TDD (Time Division Duplex)-based wireless communication system. The terminal receives a SPS downlink transmission block on a physical downlink shared channel (PDSCH) without a physical downlink control channel (PDCCH), and receives a downlink transmission block on the PDSCH that is indicated by the PDCCH having a downlink assignment index (DAI). The terminal transmits a 2-bit ACK/NACK regarding the SPS downlink transmission block and the downlink transmission block on an uplink control channel.
