Document Type and Number:
WIPO Patent Application WO/2021/029638
Kind Code:
A1
Abstract:
The present embodiments relate to a method and a device for transmitting or receiving data in an unlicensed band. One embodiment provides a method for transmitting or receiving data in an unlicensed band by a terminal, the method comprising the steps of: receiving configuration information including a parameter for configuring multiple resource block sets in an unlicensed band from a base station; identifying the multiple resource block sets on the basis of the configuration information; and transmitting or receiving data to or from the base station through at least one resource block set determined on the basis of a result which is obtained by performing listen before talk (LBT) on each of the multiple resource block sets, and is received from the base station.
