The O-RAN E2 Interface connects the Near-RT RIC to E2 nodes such as O-CU and O-DU functions.
It is the main interface used by xApps to monitor, control, and optimize RAN behavior on near-real-time timescales.
Used for
- RAN telemetry and measurements from E2 nodes.
- Near-real-time control actions from the Near-RT RIC.
- xApp-driven optimization use cases such as mobility, interference management, load balancing, and traffic steering.
Timing
E2 supports near-real-time control loops, commonly described as roughly 10 ms to 1 s.
