Claim 0:
1. A method of decoding a coded video bitstream implemented by a video decoder, comprising:
receiving the coded video bitstream comprising coded data of a mixed intra random access point (TRAP) 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-IRAP sub-picture having a trailing NAL unit type;
obtaining a reference picture list (RPL) for the second sub-picture, from the coded data;
decoding the second sub-picture using the RPL; and
generating the mixed IRAP picture based on the second sub-picture as decoded.
