Techniques for interference cancellation in sidelink communication

A method for wireless communication at a user equipment (UE), comprising:

• receiving inter-UE coordination message including sidelink assistance information, the sidelink assistance information including information associated with an interference condition;
• receiving a retransmission of the sidelink communication;
• and
• decoding the received retransmission of the sidelink communication based at least in part on the received inter-UE coordination message including the sidelink assistance information.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• generate sidelink assistance information based at least in part on an interference condition associated with an initial transmission of sidelink communication over a sidelink resource of a sidelink resource pool, the sidelink assistance information including information associated with the interference condition;
• and
• transmit an inter-UE coordination message including the generated sidelink assistance information.
