1. An apparatus for wireless communications implemented by a user equipment (UE), comprising:
a processor; and
memory coupled with the processor, wherein the memory comprises instructions
executable by the processor to cause the apparatus to:
perform one or more channel measurements of a shared frequency channel;
obtain a channel busy ratio based at least in part on comparing the one or more channel measurements with a threshold, the threshold based at least in part on a type of a listen-before-talk procedure associated with obtaining access to the shared frequency channel for a slot for transmitting a sidelink channel transmission;
perform the listen-before-talk procedure to obtain access to the shared frequency channel for the slot, wherein determining to perform the listen-before-talk procedure is based at least in part on a value of the channel busy ratio;
and
transmit the sidelink channel transmission in the slot based at least in part on a result of the listen-before-talk procedure.
