Abstract: A point cloud data transmission method according to embodiments comprises the steps of: encoding geometry data of point cloud data; encoding attribute data of the point cloud data on the basis of the geometry data; and transmitting the encoded geometry data, the encoded attribute data, and signaling data. The step of encoding the geometry data may comprise the steps of: dividing the geometry data into a plurality of compression units; generating, for each compression unit, a prediction tree on the basis of the geometry data within each compression unit; and compressing the geometry data within the compression unit by performing prediction on the basis of the prediction tree.
