2.2.1. O-RAN IP Parameters
Create custom variations of your IP.
| Parameter Name | Values | Description |
|---|---|---|
| O-RAN Mode | O-DU or O-RU | Select O-RAN distributed unit (O-DU) or O-RAN radio unit (O-RU) . |
| RU category | A and B | RU category A and B are always on. |
| Maximum Ethernet frame size | 1500 or 9000 | Specify the maximum Ethernet frame size. When value is greater than 1500, you must supply the packet size. When you select 9000, the IP creates tx_c_size, tx_u_prbusize, and source_pkt_size signals in the transmitter application Interface and transport interface. |
| Numerology | Static or Dynamic | Select static or dynamic numerology subcarrier spacing (SCS). Dynamic numerology is compile-time configurable only. When you select Dynamic Numerology, the IP sets certain restrictions on the PCID and number of eAxCs it supports. For more information, refer to Static and Dynamic Numerology in O-RAN IP Functional Description. |
| Static subcarrier spacing value (kHz) | 15, 30, 60, 120, 240 | Select the SCS for static numerology. |
| Enable companding | Off or on | Turn on for compression and decompression for U-plane IQ data. |
| ulaw compression | Off or on | Turn on for µ-law compression and decompression for U-plane IQ data. This parameter is available when you turn on Enable companding. This parameter is unavailable when you turn off Enable companding. You can turn on either or both Block floating-point compression and ulaw compression |
| Block floating-point compression | Off or on | Turn on for block floating-point compression and decompression for U-plane IQ data. This parameter is available when you turn on Enable companding. This parameter is unavailable when you turn off Enable companding. You can turn on either or both Block floating-point compression and ulaw compression |
| Enable Digital Power Scaling | On or off | Digital power scaling is supported for block floating-point compression and decompression only. |
| Avalon Streaming data width | 128 when Enable companding is turned on. 64 when Enable companding is turned off. | Specify the Avalon streaming data width. |
| Enable C plane | Off or on | Turn on for the C-plane. |
| Enable U-plane Fragmentation | Off or on | Turn on for U-plane fragmentation. The ORAN Design Example does not support U-plane fragmentation. |
| Programmable U-Plane Fragmentation FIFO Depth | 512, 1024, 2048 | User configurable FIFO depth for U-plane fragmentation. |
| Enable C-plane Fragmentation | Off or on | Turn on for C-plane fragmentation. The ORAN Design Example does not support C-plane fragmentation. |
| Programmable C-Plane Fragmentation FIFO Depth | 512, 1024, 2048 | User configurable FIFO depth for C-plane fragmentation. |
| Fragmentation Supported Number of eAxC Channel(s) | 0x001 to 0x100 | Number of eAxC channels that the fragmentation supports. Set this parameter to the number of unique eAxC IDs you expect from the application layer. |
