Abstract
Disclosed relates to a method, device, and system for performing downlink transmission. Specifically, the disclosed relates to a method including when the downlink signal includes a physical downlink shared channel (PDSCH) and a channel in the specific cell is sensed to be idle for a first predefined interval, wherein the processor performs backoff after the second predefined time in order to perform the downlink transmission, and when the downlink transmission includes a Discovery Reference Signal (DRS) and the channel in the specific cell is sensed to be idle for a second predefined interval, performing the downlink transmission immediately after the second predefined interval, and a device and system therefor.
