Transmitting resource collision indication on sidelink feedback channel

A first user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• identify a collision on a victim resource based at least in part on an aggressor reservation transmitted by a second UE;
• and
• transmit, to the second UE via a sidelink feedback channel, a resource collision indication that indicates at least one of the victim resource or the aggressor reservation, wherein the resource collision indication is multiplexed on one or more resources that are useable for sidelink feedback.

A first user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive, from a second UE via a sidelink feedback channel, a resource collision indication that indicates at least one of a victim resource or an aggressor reservation transmitted by the first UE, wherein the resource collision indication is multiplexed on one or more resources that are useable for sidelink feedback;
• and
• perform an action based at least in part on the resource collision indication.
