Abstract: Discussed is a method for transmitting a discovery signal. The method is performed by a cell of a base station and includes transmitting, to a user equipment (UE), measurement configuration information including a sub-frame offset, wherein the sub-frame offset indicates an offset between a secondary synchronization signal (SSS) and a channel-state information reference signal (CSI-RS) in a discovery signal; transmitting the SSS in the discovery signal on a first sub-frame; and transmitting the CSI-RS on a second sub-frame which is determined based on the sub-frame offset and the first sub-frame for the SSS in the discovery signal.

Abstract: Provided are a method for transmitting data in an unlicensed band and a device using the same. A transmission node generates a signal to be transmitted in the unlicensed band, and performs listen before talk (LBT) according to the type of the generated signal. If a wireless medium is idle as a result of the LBT, the transmission node transmits the generated node in the unlicensed band.
