Abstract: A method and apparatus for determining a length of a physical downlink shared channel (PDSCH) (or, a partial subframe) in a wireless communication system is provided. A user equipment (UE) detects at least one of starting orthogonal frequency division multiplexing (OFDM) symbol or ending OFDM symbol of a PDSCH in an unlicensed carrier, and determines the length of the PDSCH in the unlicensed carrier based on the at least one of the starting OFDM symbol or the ending OFDM symbol of the PDSCH in the unlicensed carrier. The UE may detect the at least one of starting OFDM symbol or ending OFDM symbol based on a physical downlink control channel (PDCCH) or a reference signal (RS) pattern.

Abstract: Provided are a method and a device whereby a synchronization signal is transmitted and received. One embodiment of the present invention involves using one of a plurality of cells (first cell hereinbelow) in order to transmit synchronization signal setting information of a cell (second cell hereinbelow) set in an unlicensed band of the plurality of cells. The synchronization signal is transmitted on the second cell, based on the synchronization signal setting information. The synchronization signal is used in order to acquire time and frequency synchronization with the second cell.
