Classification: CPC H | IPC H

Claim 0:
1. An Open Radio Access Network, O-RAN, comprising:
a fronthaul, FH, interface over which an O-RAN Distributed Unit, O-DU, and an O-RAN Radio Unit, O-RU, communicate with one another and exchange O-RAN standard defined user-plane, U-plane, packets and control-place, C-Plane, packets,
wherein said fronthaul interface carries control and management information via management-pane (M-Plane) message exchange, and timing synchronization is achieved in accordance with synchronization-plane (S-Plane) procedures, and
wherein said O-RAN accommodates communications via 2G and 3G based mobile networks, wherein said O-DU for a 2G based mobile network comprises modules for functions:
(a) TCH (Traffic Channel)/CCH (Control Channel) for generation/reception;
(b) encoding/decoding and interleaving/de-interleaving;
(c) burst handling, multiplexing/de-multiplexing;
(d) encoding and modulation/demodulation functions;
(e) additional DFE (digital front end) functions; and
(f) FH interface functions and real time control; and, wherein said O-DU for a 3G based mobile network comprises modules for functions,
(a) TCH/CCH generation/reception;
(b) Forward Error Correction (FEC) encoding/decoding;
(c) interleaving/de-interleaving, spreading/de-spreading, scrambling de-scrambling;
(d) modulation and filtering/filtering-demodulation functions;
(e) processing to convert to frequency domain and target sample rate and additional DFE functions; and
(f) FH interface functions and real time control.
