Claim 6:
7. A user equipment (UE), comprising:
a transceiver configured to connect to a primary serving cell (PCell) operating on a licensed frequency spectrum, connect to a secondary serving cell (SCell) operating on an unlicensed frequency spectrum, to monitor the SCell, to receive a discovery signal on the SCell, and to receive a channel state information reference signal (CSI-RS) on the SCell during discovery signal occasions; and
a processor configured to determine an idle status of the SCell, wherein the transceiver is further configured to transmit data on the SCell based on the idle status of the SCell, and to drop a configured sounding reference signal (SRS) transmission based on a carrier sense multiple access with collision avoidance (CSMA/CA) function.
