    Abstract: A method for decoding a channel code by a communication apparatus in a wireless communication system is disclosed. The method includes determining whether a cyclic redundancy check (CRC) of a block including a codeword having a first quality of service (QoS) has been decoded successfully by decoding the codeword having the first QoS, and if the CRC of the block has been decoded successfully, decoding a first codeword corresponding to the codeword having the first QoS, and determining whether a transport block (TB) CRC has been decoded successfully by checking the TB CRC.

    Abstract: The document relates to a method for performing communication using multiple transmission time interval (TTI) structures in a wireless communication system. In this method, a terminal transmits and receives a signal through a resource region in which a first subframe corresponding to a TTI (short TTI) of a first length and a second subframe corresponding to a TTI (short TTI) of a second length longer than the first length are multiplexed in a frequency divisional multiplexing (FDM) manner, and when a second link direction of a signal transmitted through the second subframe in a specific time interval is different from a first link direction of a signal transmitted through the first subframe, the specific time interval of the second subframe is not used for signal transmission in the second link direction.
