1. A method for a User Equipment (UE), the method comprising:
receiving a system information block (SIB) via radio resource control (RRC) signaling, the SIB comprising a listen before talk (LBT) configuration element, the LBT configuration element including a transmission configuration indicator (TCI) state parameter indicating potential TCI states;
receiving a Downlink Control Information (DCI) message, the DCI message indicating an enabled TCI state for a channel occupancy time (COT), the enabled TCI state associated with one of the potential TCI states;
decoding the DCI message and determining the enabled TCI state for the COT; and
applying the enabled TCI state for the COT as indicated in the DCI message.
