uint8_t | ud_iq_width:4 |
uint8_t | ud_comp_meth:4 |
This parameter defines the compression method and IQ bit width for the user data in the data section. This field is absent from U-Plane messages when the static IQ format and compression method is configured via the M-Plane. In this way a single compression method and IQ bit width is provided (per UL and DL, per LTE and NR) without adding more overhead to U-Plane messages.

uint8_t ud_iq_width |
Bit width of each I and each Q 16 for udIqWidth=0, otherwise equals udIqWidth e.g. udIqWidth = 0000b means I and Q are each 16 bits wide; e.g. udIQWidth = 0001b means I and Q are each 1 bit wide; e.g. udIqWidth = 1111b means I and Q are each 15 bits wide
