When the 5G NR standard is supported the control data interface is 40 bits with the fields shown in the following table for LDPC encode.
| Field | Bits | Range | Description |
|---|---|---|---|
| max_schedule | 39:38 | 0 to 3 |
Maximum number of blocks that can be interleaved by the LDPC encoder while processing this block. 0 = Default scheduling behavior. See LDPC Block Interleaving for details. |
| mb | 37:32 | 4 to 46 | Number of parity bits as a multiple of Z (Z*mb), thereby controlling code rate. |
| id | 31:24 | 0 to 255 | External block identifier to be passed through to status output. |
| 23:9 | - | Reserved | |
| bg | 8:6 | 0 to 4 | Base graph |
| z_set | 5:3 | 0 to 7 | Base graph cyclic shift set |
| z_j | 2:0 | 0 to 7 | Lifting factor (Z) j component 1 |
