Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, one or more downlink reference signals on an unlicensed carrier. The UE determines that the base station occupies the unlicensed carrier for a predetermined first channel occupancy time based on the one or more downlink reference signals. The UE receives, on the unlicensed carrier and in the predetermined first channel occupancy time, a control burst including a plurality of down link control channels. The UE attempts to decode a first down link control channel directed to the UE from the control burst.

Abstract: A method executed by a User Equipment (UE) operating in a Frame-Based Equipment (FBE) mode is provided. The method includes the following steps: determining a starting time and a periodicity of a first Fixed Frame Period (FFP) of a cell on an operating channel of an unlicensed band; determining a starting time and a periodicity of a second FFP for initiating an uplink transmission to the cell; performing a Listen-Before-Talk (LBT) procedure on the operating channel of the unlicensed band; and performing the uplink transmission to the cell using a first uplink resource in the second FFP in response to the LBT procedure indicating that the operating channel of the unlicensed band is clear.
