1. A decoding method, comprising:
determining a reference picture list for a target sub-picture of a target picture; and
performing decoding on the target sub-picture using the reference picture list for the target sub-picture,
wherein whether a common reference picture list is shared for all sub-pictures including the target sub-picture in the target picture is determined,
the common reference picture list is configured and used as the reference picture list for the target sub-picture in a case that it is determined that the common reference picture list is shared for all sub-pictures including the target sub-picture in the target picture, and
a scale value is derived in a configuration for the reference picture list for the target sub-picture in a case that a first scale of the target sub-picture and a second scale of a reference picture of the target sub-picture are different from each other.
