Abstract:
A method of transmitting a discovery reference signal (DRS) by a base station in a wireless access system supporting an unlicensed band, includes transmitting the DRS in a DRS occasion via the unlicensed band, wherein the DRS includes a secondary synchronization signal (SSS), wherein the DRS is transmitted in a subframe (SF) among SF #1, SF #2, SF #3, SF #4, SF #6, SF #7, SF #8, and SF #9, and wherein the SSS is generated based on a SSS sequence related to a SF number where the DRS occasion occurs.
