Abstract
Disclosed is a method for transmitting an uplink signal by a terminal in a non-licensed band. In particular, the method comprises: performing a clear channel assessment (CCA) on the non-licensed band; and transmitting the uplink signal on a specific slot on the basis of the result of performing the CCA, wherein when the specific slot is a random access channel (RACH) slot, the uplink signal is transmitted on the basis of a default timing advanced (TA) value for RACH signal transmission.
