Claim 20:
21. A base station for enhanced channel occupancy sharing for random access, RA, and physical uplink control channel, PUCCH in an unlicensed spectrum, the base station comprising:
processing circuitry configured to:
receive, from a wireless device, a first transmission on a channel in the unlicensed spectrum, the first transmission associated with a procedure;
based on the first transmission, determine a maximum channel occupancy time, MCOT, duration, the MCOT duration being associated with a first channel sensing procedure performed by the wireless device, the MCOT duration comprising an amount of time during which the wireless device and the base station can transmit on the channel in the unlicensed spectrum;
determine if the MCOT duration has expired;
prior to transmitting a second transmission to the wireless device, determine to perform a second channel sensing procedure based on the determination regarding the MCOT duration's expiration;
transmit the second transmission to the wireless device, the second transmission comprising a first listen-before-talk, LBT, scheme for a third transmission associated with the procedure.
