1. A method implemented in a radio node, the method comprising:
determining: (i) a maximum channel occupancy time (MCOT) value; and (ii) at least one listen-before-talk (LBT) parameter setting for one or more LBT parameters, wherein at least one of the MCOT value and the at least one LBT parameter setting is determined based on an energy detection (ED) threshold value used to access a channel in an unlicensed spectrum; and
performing a LBT procedure to gain access to the channel and a transmission on the channel according to the at least one LBT parameter setting and the MCOT value.
