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. In response to determining that the channel in the unlicensed spectrum is available, a maximum channel occupancy time, MCOT, duration associated with the first channel sensing procedure is determined. The MCOT duration is 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. 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.
