Claim 16:
17. A decoding device, comprising:
a receiver configured to receive a coded video bitstream containing:
coded data of a mixed intra random access point (IRAP) picture including a first sub-picture and a second sub-picture, wherein the first sub-picture and the second sub-picture are each capable of including more than one slice, and wherein the first sub-picture is an TRAP sub-picture having an instantaneous decoding refresh (IDR) network abstraction layer (NAL) unit type or a clean random access (CRA) NAL unit type and the second sub-picture is a non-TRAP sub-picture having a trailing NAL unit type; and
coded data of a reference picture list (RPL) for the second sub-picture;

a memory coupled to the receiver, the memory storing instructions; and
a processor coupled to the memory, the processor configured to execute the instructions to cause the decoding device to:
decode the second sub-picture using the RPL; and
generate the mixed TRAP picture based on the second sub-picture as decoded.
