1. A transmitting node for wireless communication, comprising:

one or more memories; and

one or more processors, coupled to the one or more memories, configured to cause the transmitting node to:

perform a directional listen-before-talk (LBT) using a sensing beam;

start a channel occupancy time (COT) after the directional LBT based at least in part on a time stamp corresponding to the start of the COT; and

perform, to a receiving node, during the COT, after a pause corresponding to the time stamp and after an observation window corresponding to a counter initiated by the transmitting node, one or more transmissions during the COT using one or more transmit beams that are included in the sensing beam.
