Version 3.0.0

OAI FlexRIC Integration

1. Installation of OAI and flexRIC
2. RRC Release xApp with documentation
3. Handover xApp with documentation
4. Multiple UE support
5. Channel Model Support (RFSim)

Secure Slicing xApp

1. Intrusion detection for malicious user equipment (UE).
2. Secure slicing capability for malicious UE containment.
3. Provided documentation for deploying and running the Secure Slicing xApp

Version 2.0.0

1. Support 4G and 5G NSA (with srsRAN-4G codebase)
2. Support Non-RT RIC
   • E2-like support for srsRAN
   • Lightweight implementation of E2 that does not use ASN.1 encoding and a simplified subscription process
   • SCTP-based connection between RAN and xApp, which is the same as E2
   • Supports control of PHY and MAC layers
3. E2-like xApps (Python-based)
   • Example machine learning xApp (ric-app-ml-e2like) which receives I/Q data from the RAN and sends control messages
   • Does not include model, but allows one to be easily dropped in
   • Interference classification xApp (ric-app-ic-e2like) which classifies interference through spectrograms and controls the RAN through uplink MCS
   • Includes trained model
   • Documentation provided for developing and deploying custom E2-like xApps
4. Multiple UE support ZMQ
