METHOD, DEVICE, AND SYSTEM FOR TRANSMITTING SIGNALS IN UNLICENSED BAND

WIPO Patent Application WO/2017/078463

A1

The present invention relates to a method, a device, and a system for transmitting downlink signals. In particular, the present invention relates to a method, and a device and system for same, the method comprising the steps of: monitoring a first common control channel indicating the DL interval of SF #(n-1) and SF #n; monitoring a second common control channel indicating the DL interval of SF #n and SF #(n+1); and performing a downlink reception process in SF #n on the basis of the result of the detection of the first and second common control channels, wherein if the detection of the first common control channel fails, if the detection of the second common control channel succeeds, and if the DL interval of SF #n is a part of SF #n, only the detection process of a first physical channel/signal is permitted in SF #n and the first physical channel/signal includes a discovery reference signal (DRS).
