1. A method in a user device for scheduling an uplink transmission with a base station that communicates with the user device via a shared carrier, the method comprising:
receiving, by the user device and from the base station, a configuration that indicates (i) a first channel access procedure for the user device to perform prior to transmitting the uplink transmission and (ii) at least one time-frequency resource at an occasion at which the user device is to transmit the uplink transmission;
initiating, by the user device, the first channel access procedure;
receiving, by the user device and from the base station via the shared carrier, a signal indicating at least a portion of a channel occupancy time (COT) during which the shared carrier is available to the base station; and
performing, by the user device, a second channel access procedure before transmitting the uplink transmission when the occasion is within the COT.
 
15. A user device for scheduling an uplink transmission with a base station that communicates with the user device via a shared carrier, the user device configured to:
receive, from the base station, a configuration that indicates (i) a first channel access procedure for the user device to perform prior to transmitting the uplink transmission and (ii) at least one time-frequency resource at an occasion at which the user device is to transmit the uplink transmission;
initiate the first channel access procedure;
receive, from the base station via the shared carrier, a signal indicating at least a portion of a channel occupancy time (COT) during which the shared carrier is available to the base station; and
perform a second channel access procedure before transmitting the uplink transmission when the occasion is within the COT.
