Abstract: Disclosed is a method by which a terminal decodes a codeword in a wireless communication system. Specifically, the method may comprise: receiving a plurality of codewords; and decoding the plurality codewords on the basis of successive interference cancellation (SIC). In particular, the SIC may be performed on the basis of a decoding policy for decoding the plurality of codewords. In particular, the decoding policy may be determined by a neural network trained on the basis of a state and a reward related to the plurality of codewords.

Abstract: The disclosure of the present invention proposes a wireless communication method. The method may comprise: performing a downlink (DL) reception on a DL resource; and performing an uplink (UL) transmission on a UL resource. The UL resource and the DL resource may use different numerologies each other. The numerologies may be defined by a subcarrier spacing and a cyclic prefix (CP) length.

Abstract: Provided are a method for performing a random access process in an unlicensed band, and a device using the same. The device receives a random access preamble (RAP) order instructing the transmission of a RAP. The device performs a clear channel assessment (CCA) in an unlicensed cell during an RAP window so as to transmit the RAP when the device succeeds in CCA.

Abstract: Disclosed are a method for transmitting and receiving an uplink demodulation reference signal (DMRS) in a wireless communication system, and an apparatus therefore. Particularly, a method by which a terminal transmits a DMRS in a wireless communication system comprises the steps of: receiving, from a base station, downlink control information (DCI) for physical uplink shared channel (PUSCH) scheduling; generating a DMRS sequence for the PUSCH; and mapping the DMRS sequence to a physical resource, wherein the DMRS sequence can be mapped with the spacing of a predetermined resource element (RE) within the symbol to which the DMRS sequence is mapped.

Abstract: The present disclosure provides a method for receiving a physical downlink shared channel (PDSCH) by a terminal in a wireless communication system. Specifically, the method may comprise: transmitting a physical random access channel (PRACH); monitoring a downlink control channel (DCI) for scheduling a PDSCH related to the PRACH; and receiving the PDSCH on the basis of the DCI, wherein the DCI is detected on the basis of a radio network temporary identifier (RNTI).

Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size, methods for determining the time when the adjusted contention window size is applied, methods for distinguishing between a collision and a channel error, and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when it is determined through the performed channel access procedure that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal through the unlicensed band; receiving hybrid automatic repeat and request acknowledgment (HARQ-ACK) information corresponding to the transmission burst; and adjusting the CWS using the number of DTX states in the HARQ-ACK information when the transmission burst is scheduled in a self-carrier scheduling scheme.
