1. A method, comprising:
at a user equipment (UE) in a wireless network including a next generation NodeB (gNB):
determining a configuration for an uplink (UL) transmission resource with respect to a listen before talk (LBT) operation on an unlicensed spectrum; and
transmitting uplink control information (UCI) on the UL transmission resource based on the configuration subjected to the LBT operation, wherein the transmitting the UCI on the UL transmission resource includes transmitting the UCI during a shared channel occupancy time (COT) initiated by the gNB in an LBT carrier of a carrier aggregation (CA) for the LBT operation.
