O-RAN RU IPs, M-Plane Software and System Development Environment (SDE)

RF DSP offers O-RAN Radio Unit (O-RU) IP cores that implements the low PHY baseband functions of the eNB/gNB base station and 7.2x split eCPRI/O-RAN fronthaul interface with an O-RAN Distributed Unit (O-DU) which implements the high PHY. This O-RU IP includes:

• O-RAN fronthaul eCPRI/RoE over IP and UDP, supporting 2T2R to 64T 64R massive MIMO.

• Multiple bands and component carriers, mixed numerology, optional carrier combining with NR + LTE+, LTE-M/NB-IoT and NR mixed numerology support, all with real-time C-plane control.

• FFT/IFFT and PRACH U-plane processing, IQ compression and decompression (block floating point, block scaling and mu-law, static or dynamic), optional beamforming, optional O-RAN Category B.

• Embedded software processing of PTP 1588 messages and S-plane reference designs.

• Packet classification of M-plane messages and API to M-plane software.

• IQ interfaces: to Ethernet fronthaul, DUC/DDC and RF transceivers

• Processor interface: for M-plane external CPU processing

• Radio clock interface: 100Hz radio frame clock input. Optional 100Hz radio frame clock output from the S-plane reference hardware circuit.

• Optional features and extension types, design services for customization and porting available
