Claim 0:
1. A method performed by a wireless device for enhanced channel occupancy sharing for random access, RA, and physical uplink control channel, PUCCH, in an unlicensed spectrum, the method comprising:
for a first transmission of a procedure, selecting a first channel sensing procedure for determining availability of a channel in the unlicensed spectrum;
based on the first channel sensing procedure, determining that the channel in the unlicensed spectrum is available;
in response to determining that the channel in the unlicensed spectrum is available:
determining a maximum channel occupancy time, MCOT, duration associated with the first channel sensing procedure, the MCOT duration comprising an amount of time in which the wireless device and a network node are allowed to transmit on the channel in the unlicensed spectrum for the procedure;
transmitting the first transmission during the MCOT duration;
receiving a second transmission from the network node, the second transmission comprising a first listen-before-talk, LBT, scheme for a third transmission associated with the procedure;
determining a second channel sensing procedure for a second transmission; and
updating the MCOT duration based on the second channel sensing procedure for the third transmission.
