Method and device for transmitting discovery reference signal in wireless access system supporting unlicensed band
The present invention relates to a wireless access system supporting an unlicensed band, methods for configuring a discovery reference signal (DRS), methods for re-configuring subframes for same, methods for transmitting a DRS, and devices for supporting same. A method for a base station transmitting a discovery reference signal (DRS), according to one embodiment of the present invention, comprises: a step of configuring a DRS transmitted from an unlicensed band cell (Ucell) configured in an unlicensed band; and transmitting the configured DRS during a DRS opportunity, wherein the DRS includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a cell-specific reference signal (CRS), wherein the SSS is generated on the basis of a subframe (SF) number of a subframe in which the DRS opportunity has occurred, wherein the SSS is generated on the basis of a sequence corresponding to SF number 0 when the SF number is between SF numbers 0 to 4, and the SSS is generated on the basis of a sequence corresponding to SF number 5 when the SF number is between SF numbers 5 to 9.
