RAN intelligent controllers, xApps and rApps.

Technologies

• Near-real-time RIC and E2 A platform at 10 ms–1 s timescales that hosts xApps controlling RAN nodes over the E2 interface.
• E2 service models Standard data and control models for KPIs, RAN control and cell configuration exposed to xApps.
• xApps Applications for traffic steering, interference handling, slicing assurance and scheduling at near-real-time scale.
• Non-real-time RIC and A1 Policy and model management above 1 s timescales inside the SMO, sending guidance to the near-RT RIC over A1.
• rApps and the R1 interface Portable non-real-time applications for energy, planning and optimisation using SMO services over R1.
• Conflict mitigation between applications Detecting and resolving cases where two apps try to change the same parameter in opposite directions.
• RIC use cases Traffic steering, QoE optimisation, massive MIMO tuning, slice assurance and anomaly detection as defined use cases.
• Real-time control at the DU (dApps) Research into sub-10 ms control loops running next to the DU on live radio data.
