1. A three-dimensional data encoding method, comprising:
generating first control information common to a plurality of subspaces;
encoding the plurality of subspaces included in a current space in which a plurality of three-dimensional points are included; and
generating a bitstream including the first control information and a plurality of encoded data respectively corresponding to the plurality of subspaces,
wherein the first control information includes information about the plurality of subspaces respectively associated with a plurality of identifiers,
each of headers of the plurality of encoded data includes information identifying a corresponding subspace, and
the headers are provided in the plurality of encoded data in one-to-one correspondence.
