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, on an unlicensed carrier and from a base station, a downlink signal including Listen-Before-Talk (LBT) parameters, the downlink signal being a non-physical layer signal. The UE performs an LBT operation based on the LBT parameters. The UE transmits an uplink signal to the base station when the LBT operation is successful.

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 detects a discovery reference signal on an unlicensed carrier. The UE determines timing information of a base station based on a location of the discovery reference signal in a transmission opportunity window of the base station. The UE determines resource elements of a down link control channel transmitted by the base station based on the timing information. The UE decodes the down link control channel.
