at least one memory; and
at least one processor coupled to the at least one memory and configured to cause the sidelink device to:
transmit sidelink control information (SCI) reserving a set of resources for one or more retransmissions of a message, the set of resources identifying one or more reserved resources in a time domain;
identify a skipped transmission associated with one or more of the set of resources reserved by the sidelink device for the one or more retransmissions; and
transmit a cancelation indication including a backward indication indicating the skipped transmission after at least one of the one or more reserved resources has occurred, the cancelation indication indicating that the skipped transmission corresponds to a previous reserved resource that has already occurred in the time domain for the one or more retransmissions.
