What is the formula to calculate the values of my I and Q in IQ packets?

Hi all, I need to know how we calculate the IQ values of our captured packets. In my case, 5g nr packets with no compression is used.

Assuming that it is, here is the relevant function from epan/dissectors/packet-oran.c

/* Special case for uncompressed/16-bit value */

static float uncompressed_to_float(guint32 h)

{

gint16 i16 = h & 0x0000ffff;

return ((float)i16) / 0x7fff;

}
