Claim 22:
23. A device for encoding a point cloud, the device comprising:
a memory configured to store at least a portion of the point cloud; and
one or more processors implemented in circuitry and configured to:
obtain a value of a secondary residual for geometry coding a current predictive tree node of the point cloud; and
encode the value of the secondary residual, wherein, to encode the value, the one or more processors are configured to:
encode, using a first set of context-adaptive binary arithmetic coding (CABAC) contexts, prefix bins of a syntax element, the syntax element having a value that specifies an absolute value of the value of the secondary residual; and
encode, using a second set of CABAC contexts that is different than the first set of contexts, suffix bins of the syntax element.
