Abstract: A method for channel sensing in an unlicensed band and transmitting downlink signals in a wireless communication system is disclosed. The method is performed by a transmission node configured to transmit the downlink signal after the channel sensing. The method includes sensing a channel scheduled to transmit downlink signals on a secondary cell (S-Cell) in the unlicensed band, and if the channel scheduled to transmit the downlink signals is determined to be in an unoccupied state according to the channel sensing, transmitting the downlink signals through a secondary cell (S-Cell) transmission structure having a boundary of a transmission unit shifted by a specific time index from a boundary of a transmission unit of a primary cell (P-Cell) transmission structure. The specific time index may be selected from among a plurality of candidate time indexes.

Abstract: The present invention relates to methods for efficiently relaying device to device (D2D) data utilizing a relay terminal (rUE) in a wireless access system supporting D2D communication, and apparatuses for supporting the methods. As one example of the present invention, a method for relaying D2D data by a relay terminal in a wireless access system supporting D2D communication may comprise the steps of: receiving a scheduling allocation (SA) signal for allocating a resource area where the D2D data are transmitted; receiving at least one D2D data; and relaying, from among the at least one D2D data, only the first D2D data received from a terminal out of coverage. The first D2D data among the at least one D2D data can be detected on the basis of a SA signal and a medium access control header relating to the at least one D2D data.
