1. A device for coding point cloud data, the device comprising:
a memory configured to store point cloud data; and
a processing system comprising one or more processors implemented in circuitry, the processing system being configured to:
determine that inter prediction data is coded for point data of a current node of an octree of the point cloud data;
in response to the inter prediction data being coded for the point data of the current node, avoid coding a single occupancy value for the point data of the current node, the single occupancy value indicating whether only a single sub-node of the current node includes one or more points; and
code the point data of the current node using the inter prediction data.
