1. A device comprising:
a memory configured to store point cloud data; and
one or more processors coupled to the memory and implemented in circuitry, the one or more processors configured to:
obtain a value for a first laser, the value for the first laser indicating a number of probes in an azimuth direction of the first laser;
decode a syntax element for a second laser, wherein the syntax element for the second laser indicates a difference between the value for the first laser and a value for the second laser, the value for the second laser indicating a number of probes in the azimuth direction of the second laser;
determine the value for the second laser indicating the number of probes in the azimuth direction of the second laser based on the first value and the indication of the difference between the value for the first laser and the value for the second laser; and
decode a point of the point cloud data based on the number of probes in the azimuth direction of the second laser.
