1. A device for encoding point cloud data, the device comprising:
a memory to store the point cloud data; and
one or more processors coupled to the memory and implemented in circuitry, the one or more processors configured to:
determine that occupied child nodes of a node form a single plane perpendicular to a first axis of a coordinate system, wherein the first axis is a horizontal axis and the occupied child nodes contain points represented by the point cloud data;
determine, from a plurality of contexts consisting of 8 contexts, a context for a horizontal plane position of the node, wherein the horizontal plane position indicates a position of the plane perpendicular to the first axis;
perform arithmetic encoding on a syntax element indicating the horizontal plane position using the determined context; and
based on the determination that the occupied child nodes of the node form the plane perpendicular to the first axis, not encoding of child nodes that are not in the plane perpendicular to the first axis.
