Radio link control forward compatibility for multicast messages or broadcast messages

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

• one or more memories storing processor-readable code;
• and
• one or more processors coupled with the one or more memories and operable to cause the UE to:
• receive, from a network entity, a multicast message or a broadcast message having a radio link control (RLC) format associated with an RLC acknowledged mode (RLC-AM);
• decode the multicast message or the broadcast message to identify information associated with the RLC-AM;
• and
• operate in accordance with the RLC-AM in association with one or more bits associated with the RLC-AM in a header of the multicast message or the broadcast message.
