1. A device comprising:
a processor configured to:
receive, from a content server, a media presentation description (MPD) file;
determine, from the MPD file, a geometry-based point cloud compression (G-PCC) adaptation set, wherein the G-PCC adaptation set is an adaptation set associated with a G-PCC component;
determine a G-PCC tile identifier associated with a tile, wherein the G-PCC tile identifier is determined from:
a GPCCComponent descriptor associated with the G-PCC adaptation set, when the GPCCComponent descriptor is signaled at adaptation set level, and
a GPCCTileID descriptor associated with the G-PCC adaptation set, when all G-PCC components of the tile are available in one track;
request the G-PCC component using the G-PCC tile identifier associated with the tile; and
receive the G-PCC component.
