1. A method for point cloud decoding, the method being performed by at least one processor, and the method comprising:
receiving, from a bitstream, multiple partitions of a point cloud, the multiple partitions comprising a first partition and a second partition;
determining, for each of the multiple partitions into which the point cloud is partitioned, a maximum number of tiles in a frame used to pack a respective one of the multiple partitions, among a group of frames, the maximum number of tiles for the first partition being different than the maximum number of tiles for the second partition; and
decoding the point cloud based on a packing of each of the multiple partitions into the maximum number of tiles obtained for a respective one of the multiple partitions, in each of the group of frames, wherein the packing is based on each of the maximum number of tiles for the first partition and the maximum number of tiles for the second partition not being shared by any of the multiple partitions and remaining the same for all frames in the group of frames.
