Abstract: For supporting a new radio access technology (new RAT, or NR), a frame structure for the new RAT may be configured. A network node configures a frame in which a first cyclic prefix (CP) is allocated to a first symbol in every 0.5 ms and a second CP is allocated to remaining symbols in every 0.5 ms. In this case, a length of the first CP is longer than a length of the second CP.

Abstract: The present invention relates to a wireless communication system and provides a method and a device for same. The method comprises the steps of: receiving information about SPS transmission periods; confirming information about the number of SPS repetitions; and receiving SPS data, which is newly and repeatedly transmitted in every SPS transmission period, on the basis of the SPS transmission periods and the number of the SPS repetitions, wherein, if the SPS transmission periods are greater than the number of the SPS repetitions, a frequency band in which the SPS data is received is maintained to be the same in every SPS transmission period and, if the SPS transmission periods are smaller than the number of the SPS repetitions, the frequency band in which the SPS data is received is switched in every SPS transmission period.

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.

Abstract: A network node in a new radio access technology (RAT) configures a fixed resource on which transmission direction is fixed and a flexible resource on which transmission direction is changeable, and transmits a single channel which is mapped to the fixed resource and the flexible resource. The single channel may be divided into a first mini channel which is mapped to the fixed resource and a second mini channel which is mapped to the flexible resource.
