Abstract
An LBT method and apparatus are disclosed for a WTRU and gNB. A method may comprise receiving a gNB beam direction schedule and an LBT measurement configuration. The WTRU may switch a receiver so as to receive a beam based on the beam direction schedule and monitor for a DCI. The WTRU may be configured to determine whether there is a transmission for the WTRU and if there is, the transmission may be received. The transmission may be a DCI for an uplink transmission of the WTRU. A WTRU may be configured to receive the gNB beam direction schedule and the LBT measurement configuration at a start of an MCOT.
