Configuring a sidelink hybrid automatic repeat request

An apparatus comprising a first sidelink device, the apparatus further comprising:

• a transceiver that:
• communicates with a second sidelink device using a first sidelink communication interface, wherein the second sidelink device communicates with a third sidelink device using a second sidelink communication interface;
• and
• transmits a sidelink hybrid automatic repeat request configuration to the second sidelink device via the first sidelink communication interface;
• wherein the sidelink hybrid automatic repeat request configuration comprises a sidelink hybrid automatic repeat request feedback enable indicator, a sidelink hybrid automatic repeat request feedback disable indicator, sidelink hybrid automatic repeat request feedback options, a minimum communication range value, a cast type, a group size, a reflective indicator, a non-reflective indicator, or some combination thereof.
