1. An apparatus for wireless communications at a relay device, comprising:
at least one processor;
at least one memory coupled with the at least one processor; and
instructions stored in the at least one memory and executable by the at least one processor to cause the apparatus to:
receive control signaling indicating a channel occupancy time allocated for a first wireless device or a second wireless device and indicating a set of energy patterns, each energy pattern of the set of energy patterns comprising an on-off pattern including one or more on durations associated with a first energy level and one or more off durations associated with a second energy level;
receive a first signal comprising a first indication that the first wireless device or the second wireless device is occupying a channel in an unlicensed radio frequency spectrum band, wherein the first indication is based at least in part on the first signal having a first energy pattern of the set of energy patterns;
perform, by the relay device and based at least in part on receiving the first indication, a listen before talk procedure on the channel during the channel occupancy time allocated for the first wireless device or the second wireless device, wherein the channel is occupied by the first wireless device or the second wireless device during the channel occupancy time; and
relay signals between the first wireless device and the second wireless device over the channel during the channel occupancy time based at least in part on the relay device passing the listen before talk procedure and based at least in part on the first indication.
