determine a reference duration of a channel occupancy time (COT) for each subband of at least one subband, the reference duration being based at least in part on a subcarrier spacing (SCS) and based on reception of a physical downlink shared channel (PDSCH) transmission that is non-punctured in a corresponding subband; and
update a contention window (CW) based at least in part on reception of the PDSCH transmission during the reference duration.
