1. A method of encoding point cloud data by an apparatus, the method comprising:
encoding point cloud data in a slice; and
transmitting a bitstream containing the point cloud data,
wherein the slice is identified based on a slice identifier,
wherein the slice is included in a slice group as a sub-slice,
wherein the bitstream includes the slice identifier, slice reordering information for representing that the bitstream is sensitive to reordering for the point cloud data and node size information for representing a maximum node size related to the slice.
