Abstract: A method performed by a wireless device (110) includes, 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, it is determined that the channel in the unlicensed spectrum is available.

The wireless device transmits the first transmission during the MCOT duration and receives a second transmission from a network node (160). The second transmission includes a first listen-before-talk, LBT, scheme for a third transmission associated with the procedure.
