1. A method for signaling in cast-type indication for a wireless communication system, the method comprising:
receiving, at a first user equipment (UE), a first stage sidelink control information (SCI) format from a second UE;
decoding the first stage SCI format;
determining a second stage SCI format using the decoded first stage SCI format;
receiving the second stage SCI format;
decoding the second stage SCI format; and
determining a sidelink feedback status using the second stage SCI format,
wherein the sidelink feedback status indicates whether sidelink feedback is enabled or not enabled, and wherein second stage SCI content includes a distance setting associated with a communication range between the first UE and the second UE.
