1. A transmitter node for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to cause the transmitter node to:
determine one or more transmit beams to use for transmissions during a channel occupancy time (COT), wherein a transmit beam, of the one or more transmit beams, is associated with a first energy detection threshold (EDT);
configure a sensing beam associated with a directional listen-before-talk (LBT) procedure, wherein the sensing beam covers the one or more transmit beams, and wherein the sensing beam is associated with a second EDT that is based at least in part on an effective isotropic radiated power (EIRP) associated with the transmissions during the COT; and
transmit using the one or more transmit beams during the COT, wherein the COT is initiated based at least in part on a success of the directional LBT procedure using the sensing beam.
