In some aspects, a user equipment (UE) may identify a channel sensing mode, from one or more channel sensing modes for sensing channel availability of a sidelink channel, for a communication on the sidelink channel, each of the one or more channel sensing modes associated with a set of resources. The UE may transmit, using resources selected from the set of resources associated with the channel sensing mode, the communication on the sidelink channel in accordance with the channel sensing mode. Numerous other aspects are provided.
